    Kuptsov, Dmitriy; Gurtov, Andrei

    Explosive growth of the Internet and lack of mechanisms that validate the authenticity of a packet source produced serious security and accounting issues. In this paper, we propose validating source addresses in LAN using Host Identity Protocol (HIP) deployed in a first-hop router. Compared to alternative solutions such as CGA, our approach is suitable both for IPv4 and IPv6. We have implemented SAVAH in Wi-Fi access points and evaluated its overhead for clients and the first-hop router.

    Full Text Available The paper presents a secure protocol for communication between host and NFC reader. The protocol protection scheme uses symmetric cipher with cyclic session key generation and provides confidentiality, integrity, end parties authentication and resistance to replay attacks. Deployment scenario in a typical electronic payment system is also presented.

    Full Text Available Electronic voting protocols proposed to date meet their properties based on Public Key Cryptography (PKC, which offers high flexibility through key agreement protocols and authentication mechanisms. However, when PKC is used, it is necessary to implement Certification Authority (CA to provide certificates which bind public keys to entities and enable verification of such public key bindings. Consequently, the components of the protocol increase notably. An alternative is to use Identity-Based Encryption (IBE. With this kind of cryptography, it is possible to have all the benefits offered by PKC, without neither the need of certificates nor all the core components of a Public Key Infrastructure (PKI. Considering the aforementioned, in this paper we propose an electronic voting protocol, which meets the privacy and robustness properties by using bilinear maps.

    Recently, Li et al. proposed a dynamic identity based authentication protocol for multi-server architecture. They claimed their protocol is secure and can withstand various attacks. But we found some security loopholes in the protocol. Accordingly, the current paper demonstrates that Li et al.'s protocol is vulnerable to the replay attack, the password guessing attack and the masquerade attack.

    2011-01-01

    It is established that a single quantum cryptography protocol usually cooperates with other cryptographic systems, such as an authentication system, in the real world. However, few protocols have been proposed on how to combine two or more quantum protocols. To fill this gap, we propose a composed quantum protocol, containing both quantum identity authentication and quantum key distribution, using squeezed states. Hence, not only the identity can be verified, but also a new private key can be generated by our new protocol. We also analyze the security under an optimal attack, and the efficiency, which is defined by the threshold of the tolerant error rate, using Gaussian error function. (general)

    Little is known about the response of arbuscular mycorrhizal fungal communities to ecosystem development. We use a long-term soil chronosequence that includes ecosystem progression and retrogression to quantify the importance of host plant identity as a factor driving fungal community composition during ecosystem development. We identified arbuscular mycorrhizal fungi and plant species from 50 individual roots from each of 10 sites spanning 5-120 000 yr of ecosystem age using terminal restriction fragment length polymorphism (T-RFLP), Sanger sequencing and pyrosequencing. Arbuscular mycorrhizal fungal communities were highly structured by ecosystem age. There was strong niche differentiation, with different groups of operational taxonomic units (OTUs) being characteristic of early succession, ecosystem progression and ecosystem retrogression. Fungal alpha diversity decreased with ecosystem age, whereas beta diversity was high at early stages and lower in subsequent stages. A total of 39% of the variance in fungal communities was explained by host plant and site age, 29% of which was attributed to host and the interaction between host and site (24% and 5%, respectively). The strong response of arbuscular mycorrhizal fungi to ecosystem development appears to be largely driven by plant host identity, supporting the concept that plant and fungal communities are tightly coupled rather than independently responding to habitat. © 2014 The Authors.

    Overqualification is a form of person-job misfit that is common among those who reside in a foreign country. It is associated with poor work-related well-being and can inhibit full adjustment to the host society. The goal of our study is to examine the impact of perceived overqualification on job satisfaction and career satisfaction among immigrants. Furthermore, we investigated immigrants' host national identity as a moderator of the impact of perceived overqualification on job satisfaction and career satisfaction. We analysed longitudinal online survey data from 124 Italian and Spanish immigrants who migrated to Germany between 2000 and 2014. Regression analyses show that perceived overqualification is negatively associated with job satisfaction six months later. Furthermore, host national identity moderates the association between perceived overqualification and job satisfaction: low overqualification is beneficial for job satisfaction whereas high overqualification is a threat for job satisfaction, especially for immigrants who identify strongly with the host society. We do not find corresponding direct and moderating effects on career satisfaction. We conclude that indicators of acculturation, such as host national identity, are worth considering in order to understand the impact of person-job misfit on work-related well-being among immigrants.

    We analyzed the problems of security of the information of the civil registries and identification at world level that are considered strategic. The objective is to adopt the appropriate security protocols in a conceptual model in the identity management for the Civil Registry of Ecuador. In this phase, the appropriate security protocols were determined in a Conceptual Model in Identity Management with Authentication, Authorization and Auditing (AAA). We used the deductive method and exploratory research to define the appropriate security protocols to be adopted in the identity model: IPSec, DNSsec, Radius, SSL, TLS, IEEE 802.1X EAP, Set. It was a prototype of the location of the security protocols adopted in the logical design of the technological infrastructure considering the conceptual model for Identity, Authentication, Authorization, and Audit management. It was concluded that the adopted protocols are appropriate for a distributed database and should have a direct relationship with the algorithms, which allows vulnerability and risk mitigation taking into account confidentiality, integrity and availability (CIA).

  11. Communities of Putative Ericoid Mycorrhizal Fungi Isolated from Alpine Dwarf Shrubs in Japan: Effects of Host Identity and Microhabitat.

    Dwarf shrubs of the family Ericaceae are common in arctic and alpine regions. Many of these plants are associated with ericoid mycorrhizal (ERM) fungi, which allow them to take nutrients and water from the soil under harsh environmental conditions and, thus, affect host plant survival. Despite the importance of ERM fungi to alpine plant communities, limited information is available on the effects of microhabitat and host identity on ERM fungal communities. We investigated the communities of putative ERM fungi isolated from five dwarf shrub species (Arcterica nana, Diapensia lapponica, Empetrum nigrum, Loiseleuria procumbens, and Vaccinium vitis-idaea) that co-occur in an alpine region of Japan, with reference to distinct microhabitats provided by large stone pine (Pinus pumila) shrubs (i.e. bare ground, the edge of stone pine shrubs, and the inside of stone pine shrubs). We obtained 703 fungal isolates from 222 individual plants. These isolates were classified into 55 operational taxonomic units (OTUs) based on the sequencing of internal transcribed spacer regions in ribosomal DNA. These putative ERM fungal communities were dominated by Helotiales fungi for all host species. Cistella and Trimmatostroma species, which have rarely been detected in ERM roots in previous studies, were abundant. ERM fungal communities were significantly different among microhabitats (R 2 =0.28), while the host effect explained less variance in the fungal communities after excluding the microhabitat effect (R 2 =0.17). Our results suggest that the host effect on ERM fungal communities is minor and the distributions of hosts and fungal communities may be assessed based on microhabitat conditions.

    Data communication in a computer network environment is facing serious security threats from numerous sources such as viruses, worms, Zombies etc. These threats can be broadly characterized as internal or external security threats. Internal threats are mainly attributed to sneaker-nets, utility modems and unauthorized users, which can be minimized by skillful network administration, password management and optimum usage policy definition. The external threats need more serious attention as these attacks are mostly coming from public networks such as Internet. Frequency and complexity of such attacks is much higher as compared to internal attacks. This paper presents a host based network layer screening of external and internal IP packets for logging, analyzing and real-time detection of possible IP spoofing and Denial of Service attacks. This work can also be used in tuning security rules definition for gateway firewalls. Software has been developed which intercepts IP traffic and analyses it with respect to integrity and origin of I P packet. The received IP packets are parsed and analyzed for possible signs of intrusion. The results show that by watching and categorizing composition of various transport protocol such as TCP, UDP, ICMP and others along with verifying the origin of received IP packet can help in devising real-time firewall rule and blocking possible external attack. This is highly desirable for fighting against zero day attacks and can result in a better Mean Time between Failures (MTBF) to increase the survivability of computer network. Used in a right context, packet screening and filtering can be a useful tool for provision of reliable and stable network services. (author)

  13. Metabolite comparisons and the identity of nutrients translocated from symbiotic algae to an animal host.

    2003-09-01

    Dinoflagellate algae of the genus Symbiodinium in symbiosis with marine animals release much of their photosynthetic carbon to the animal host. The compounds translocated to the host ('mobile compounds') were investigated by metabolite comparison as follows: a substrate was identified as a candidate mobile compound when comparable profiles of metabolites were generated from host metabolism of this substrate (supplied exogenously) and the endogenous mobile compounds. When the sea anemone Anemonia viridis was incubated with NaH14CO2 under photosynthesizing conditions, most of the radioactivity in the animal tissue was recovered from the low-molecular-mass fraction and distributed in the ratio 1:2:1 between the neutral, acidic and basic sub-fractions. Prominent 14C-labelled compounds included glucose, malate and glucose-6-phosphate. When the symbiosis was incubated with 14C-labelled glucose plus succinate or fumarate (but none of eight other substrate combinations tested), the 14C-labelled metabolites closely matched those obtained with NaH14CO2. These data suggest that glucose and succinate/fumarate (or metabolically allied compounds) may be important photosynthetic compounds transferred from the Symbiodinium cells to the tissues of A. viridis. Metabolite comparisons can be applied to study nutritional interactions in symbioses involving photosynthetic algae and, with appropriate modification, other associations between microorganisms and plants or animals.

    2013-10-01

    Two new species of diphyllidean cestodes of the genus Echinobothrium, each hosted by a different skate species in the Raja miraletus complex, are described. Echinobothrium mercedesae n. sp. is described from R. cf. miraletus 2 off Senegal. Echinobothrium yiae n. sp. is described from R. cf. miraletus 1 off South Africa. Both species are small worms that differ from their 29 described congeners in the combination of number of cephalic peduncle spines per column, hook formula, number and arrangement of testes, and arrangement of vitelline follicles. They are easily distinguished from one another in that whereas the vitelline follicles of E. yiae n. sp. are circumcortical, they are lateral in E. mercedesae n. sp., and also in number of cephalic peduncle spines per column (14-17 vs. 10-12). Echinobothrium yiae n. sp. is also unusual in that the cephalic peduncle spines stop short of the anterior margin of the peduncle. In addition, although the paucity of available material precluded their formal description, evidence of 2 additional new species parasitizing R. miraletus also from Senegal is presented. In combination these worms provide support for the interpretation that what is currently recognized as Raja miraletus actually consists of a complex of geographically restricted species, rather than a polymorphic species of multiple parapatric or allopatrically distributed populations. This interpretation is not only supported by previously published molecular data, but also by newly collected morphological data involving differences in the color patterns of disc ocelli among host specimens of the 3 forms available as a result of digital efforts to ensure the accuracy of host identifications, which are also presented here.

    Alexander (1954: 489) recorded a petrel (Aves: Procellariiformes) captured alive on board a ship in the Indian Ocean by Mr W.W.A. Phillips who, after removing some lice, liberated it the following morning. Alexander (1954) identified that petrel as the species "Pterodroma aterrima Bonaparte", now placed in the genus Pseudobulweria. The lice were kept in the collection of the then British Museum (Natural History), now the Natural History Museum, London, England. Jouanin (1955) published a new species of petrel from the Indian Ocean as Bulweria fallax. Jouanin (1957: 19) discussed the identity of the petrel identified by Alexander (1954) as Pterodroma aterrima, stating that the descriptive data given by Alexander (1954) did not clearly fit either P. aterrima or B. fallax. However, considering the geographical coordinates where the bird was captured, Jouanin (1957) believed it was more likely Bulweria fallax.

    Thirty-four patients with leukemia, two with lymphoma and 15 with aplastic anemia, were studied sequentially between 33 and 666 days after treatment with high-dose cyclophosphamide and/or total body irradiation and marrow transplantation from HLA-identical siblings. Peripheral blood mononuclear cells from patients and normals were tested for cell inhibition (CI) of cultured skin fibroblasts from patients and donors or unrelated individuals using the microcytotoxicity assay. In addition, blocking of Cl by factors in patient serum was studied. Twenty patients were tested three or more times during the first year, 15 patients were studied twice and 16 patients once. Results showed that during the first 2 mo postgrafting, mononuclear cells from 45% of the patients had neither Cl nor blocking activities, 50% had Cl and serum blocking, and 5% had Cl without blocking. As time after transplatation elapsed, the percentage of patients without Cl gradually increased, whereas the percentage of patients with Cl with or without blocking decreased. At the end of 1 yr, 89% of the patients showed neither Cl nor blocking compared with 11% who showed Cl and blocking. This trend was significant (p < 0.005). The results were in agreement with our previus conclusion that serum-blocking factors were not important in the maintenance of the stable chimeric state. Early after grafting, there was a suggestive correlation (p < 0.08) between the in vitro finding of Cl of host fibroblasts by chimeric cells and the in vivo finding of acute graft-vs-host disease. However, there was no evidence that presence or absence of serum-blocking factors early after grafting was correlated with presence or absence of graft-vs-host disease

    Full Text Available The sustainable development of the festival depends on the support and participation of residents and tourists. There are a number of practical and theoretical gaps regarding the hosts and guests in festival literature. This study attempts to fill the host–guest gap based on the theory of reasoned action to construct and exam a relationship model. Taking the 2016 Summer Festival during busy season as an example in Hualien, 1165 questionnaires were valid, and data were analyzed by SEM (structural equation modeling. Results showed that the hosts had higher perception than the guests in terms of the festival benefits, identity, and support. This study has two concept models: the guest model and the host model. In the host model, the local-development benefits have more positive relationships to affect the festival support and festival identity than the recreation-experience benefits. On the other hand, the recreation-experience benefits could affect the festival support, but the festival identity could not in the guest model. The results of this study indicate that the festival organizers or the public sectors must be pay attention to the viewpoints of the guests and hosts in order to achieve the sustainable development objectives.

  18. A Network Topology Control and Identity Authentication Protocol with Support for Movable Sensor Nodes.

    It is expected that in the near future wireless sensor network (WSNs) will be more widely used in the mobile environment, in applications such as Autonomous Underwater Vehicles (AUVs) for marine monitoring and mobile robots for environmental investigation. The sensor nodes' mobility can easily cause changes to the structure of a network topology, and lead to the decline in the amount of transmitted data, excessive energy consumption, and lack of security. To solve these problems, a kind of efficient Topology Control algorithm for node Mobility (TCM) is proposed. In the topology construction stage, an efficient clustering algorithm is adopted, which supports sensor node movement. It can ensure the balance of clustering, and reduce the energy consumption. In the topology maintenance stage, the digital signature authentication based on Error Correction Code (ECC) and the communication mechanism of soft handover are adopted. After verifying the legal identity of the mobile nodes, secure communications can be established, and this can increase the amount of data transmitted. Compared to some existing schemes, the proposed scheme has significant advantages regarding network topology stability, amounts of data transferred, lifetime and safety performance of the network.

    -specialized language in which it also serves a number of functions – some of which are quite fundamental to society as such. In other words, the lexeme identity is a polysemic word and has multiple, well, identities. Given that it appears to have a number of functions in a variety of registers, including terminologies...... in Academic English and more everyday-based English, identity as a lexeme is definitely worth having a look at. This paper presents a lexicological study of identity in which some of its senses are identified and their behaviors in actual discourse are observed. Drawing on data from the 2011 section...... of the Corpus of Contemporary American English, a behavioral profile of the distributional characteristics of identity is set up. Behavioral profiling is a lexicographical method developed by the corpus linguist Stefan Th. Gries which, by applying semantic ID tagging and statistical analysis, provides a fine...

    Despite significant differences in terms of medical training and health care context, the phenomenon of medical students' declining interest in family medicine has been well documented in North America and in many other developed countries as well. As part of a research program on family physicians' professional identity formation initiated in 2007, the purpose of the present investigation is to examine in-depth how family physicians construct their professional image in academic contexts; in other words, this study will allow us to identify and understand the processes whereby family physicians with an academic appointment seek to control the ideas others form about them as a professional group, i.e. impression management. The methodology consists of a multiple case study embedded in the perspective of institutional theory. Four international cases from Canada, France, Ireland and Spain will be conducted; the "case" is the medical school. Four levels of analysis will be considered: individual family physicians, interpersonal relationships, family physician professional group, and organization (medical school). Individual interviews and focus groups with academic family physicians will constitute the main technique for data generation, which will be complemented with a variety of documentary sources. Discourse techniques, more particularly rhetorical analysis, will be used to analyze the data gathered. Within- and cross-case analysis will then be performed. This empirical study is strongly grounded in theory and will contribute to the scant body of literature on family physicians' professional identity formation processes in medical schools. Findings will potentially have important implications for the practice of family medicine, medical education and health and educational policies.

    2017-06-01

    Despite evidence that large professional networks afford a host of financial and professional benefits, people vary in how motivated they are to build such networks. To help explain this variance, the present article moves beyond a rational self-interest account to examine the possibility that identity shapes individuals' intentions to network. Study 1 established a positive association between viewing professional networking as identity-congruent and the tendency to prioritize strengthening and expanding one's professional network. Study 2 revealed that manipulating the salience of the self affects networking intentions, but only among those high in networking identity-congruence. Study 3 further established causality by experimentally manipulating identity-congruence to increase networking intentions. Study 4 examined whether identity or self-interest is a better predictor of networking intentions, providing support for the former. These findings indicate that identity influences the networks people develop. Implications for research on the self, identity-based motivation, and professional networking are discussed.

  5. Constraints on the Nature and Distribution of Iridium Host Phases at the Cretaceous-Tertiary Boundary: Implications for Projectile Identity and dispersal on impact

    1997-01-01

    Among Cretaceous-Tertiary boundary sites worldwide, variations in the concentrations and ratios of elements commonly enriched in meteorites complicate traditional geochemical attempts at impactor identification. Yet they may provide constraints on the physical and chemical processes associated with large-body disruption and dispersal, as well as with diagenesis of projectile components. To this end, we continue our efforts to identify the mineral host-phases of projectile-derived elements, particularly for Ir, and to document their partitioning between crater deposits and ejecta resulting from the Chicxulub basin-forming impact. Building on earlier work, we used INAA to measure Ir concentrations in successively smaller splits of finely powdered impact melt breccia from the Chicxulub Crater in Mexico (sample Y6Nl9-R(b)), and K/T boundary fish clay from Stevns Klint, Denmark (sample FC-1, split from 40 kg of homogenized material intended as an analytical standard). Results for the Chicxulub sample show a heterogeneous Ir distribution and document that at least five discrete Ir-bearing host phases were isolated in subsequent splits, having Ir masses equivalent to pure Ir spheres from about 0.8 to about 3.5 mm in diameter. Three of these are within a sufficiently reduced mass of powder to warrant searching for them using backscattered electron microscopy. In contrast, successively smaller splits of the Stevns Klint fish clay show no statistically significant deviation from the reported value of 32 +/- 2 ng/g Ir, suggesting a uniform Ir host-phase distribution. For the smallest split obtained thus far (100 +/- 40 ng/g Ir), a pure Ir sphere of equivalent Ir mass would be <0.05 min in diameter. (n.b. Although homogenizing and sieving of FC-1 to <75 min obviously obscured variations in stratigraphic distribution, it is unlikely to have affected the size-frequency distribution of Ir host phases.) We previously identified micrometer-scale Ir host phases by electron

    The drastic decline in the abundance of Caribbean acroporid corals (Acropora cervicornis, A. palmata) has prompted the listing of this genus as threatened as well as the development of a regional propagation and restoration program. Using in situ underwater nurseries, we documented the influence of coral genotype and symbiont identity, colony size, and propagation method on the growth and branching patterns of staghorn corals in Florida and the Dominican Republic. Individual tracking of> 1700 nursery-grown staghorn fragments and colonies from 37 distinct genotypes (identified using microsatellites) in Florida and the Dominican Republic revealed a significant positive relationship between size and growth, but a decreasing rate of productivity with increasing size. Pruning vigor (enhanced growth after fragmentation) was documented even in colonies that lost 95% of their coral tissue/skeleton, indicating that high productivity can be maintained within nurseries by sequentially fragmenting corals. A significant effect of coral genotype was documented for corals grown in a common-garden setting, with fast-growing genotypes growing up to an order of magnitude faster than slow-growing genotypes. Algal-symbiont identity established using qPCR techniques showed that clade A (likely Symbiodinium A3) was the dominant symbiont type for all coral genotypes, except for one coral genotype in the DR and two in Florida that were dominated by clade C, with A- and C-dominated genotypes having similar growth rates. The threatened Caribbean staghorn coral is capable of extremely fast growth, with annual productivity rates exceeding 5 cm of new coral produced for every cm of existing coral. This species benefits from high fragment survivorship coupled by the pruning vigor experienced by the parent colonies after fragmentation. These life-history characteristics make A. cervicornis a successful candidate nursery species and provide optimism for the potential role that active propagation

Algal-symbiont identity established using qPCR techniques showed that clade A (likely Symbiodinium A3 was the dominant symbiont type for all coral genotypes, except for one coral genotype in the DR and two in Florida that were dominated by clade C, with A- and C-dominated genotypes having similar growth rates. CONCLUSION/SIGNIFICANCE: The threatened Caribbean staghorn coral is capable of extremely fast growth, with annual productivity rates exceeding 5 cm of new coral produced for every cm of existing coral. This species benefits from high fragment survivorship coupled by the pruning vigor experienced by the parent colonies after fragmentation. These life-history characteristics make A. cervicornis a successful candidate

    Chronic obstructive pulmonary disease (COPD) is a degenerative condition that can impair health-related quality of life (HRQoL). A number of self-management interventions, employing a variety of behavioural change techniques (BCTs), have been adopted to improve HRQoL for COPD patients. However, a lack of attention has been given to group management interventions with an emphasis on incorporating BCTs into rehabilitators' practice. This study aims to pilot and feasibly explore a social identity group management intervention, delivered by COPD rehabilitation staff to patients attending exercise pulmonary rehabilitation. Doing so will help inform the plausibility of the intervention before conducting a full trial to evaluate its effectiveness to improve HRQoL. This is a two-centre, randomised cross-over controlled trial. Two pulmonary rehabilitation centres based in the UK will be randomly allocated to two treatment arms (standard care and intervention). Outcome measurements relating to HRQoL and social identity will be completed pre- and post-exercise rehabilitation. Focus group interviews will be conducted at the end of exercise rehabilitation to capture participants' contextualised experiences of the intervention. COPD rehabilitators will undertake semi-structured interviews at the end of the trial to garner their holistic perspectives of intervention fidelity and implementation. This is the first study to adopt a social identity approach to develop a rehabilitator-led, group management intervention for COPD patients attending exercise pulmonary rehabilitation. The results of this study will provide evidence for the feasibility and sample size requirements to inform a larger study, which can ascertain the intervention's effectiveness for improving HRQoL for COPD patients.

    Full Text Available Often collective identities are classified depending on their contents and rarely depending on their forms. Differentiation between soft identity and hard identity is applied to diverse collective identities: religious, political, national, tribal ones, etc. This classification is made following the principal dimensions of collective identities: type of classification (univocal and exclusive or relative and contextual, the absence or presence of conflictsof loyalty, selective or totalitarian, objective or subjective conception, among others. The different characteristics analysed contribute to outlining an increasingly frequent type of identity: the authoritarian identity.

    The ternary commutator or ternutator, defined as the alternating sum of the product of three operators, has recently drawn much attention as an interesting structure generalizing the commutator. The ternutator satisfies cubic identities analogous to the quadratic Jacobi identity for the commutator. We present various forms of these identities and discuss the possibility of using them to define ternary algebras.

  12. Integrated Detection of Pathogens and Host Biomarkers for Wounds

    The increasing incidence and complications arising from combat wounds has necessitated a reassessment of methods for effective treatment. Infection, excessive inflammation, and incidence of drug-resistant organisms all contribute toward negative outcomes for afflicted individuals. The organisms and host processes involved in wound progression, however, are incompletely understood. We therefore set out, using our unique technical resources, to construct a profile of combat wounds which did or did not successfully resolve. We employed the Lawrence Livermore Microbial Detection Array and identified a number of nosocomial pathogens present in wound samples. Some of these identities corresponded with bacterial isolates previously cultured, while others were not obtained via standard microbiology. Further, we optimized proteomics protocols for the identification of host biomarkers indicative of various stages in wound progression. In combination with our pathogen data, our biomarker discovery efforts will provide a profile corresponding to wound complications, and will assist significantly in treatment of these complex cases.

It is important because it touches...... on the meaning of being a compassionate, good and skilled physician, making its relevance to person-centered medicine self-evident. Conclusion: Medical identity should be analyzed with reference to literature, philosophy and medical practice in order for the physician to exercise a reflective position...

  14. Identity paradoxes

    Directory of Open Access Journals (Sweden)

    Đurić Jelena

    2010-01-01

    Full Text Available The article considers paradoxical nature of identity that emerges from: 1 the very concept of identity whose abstract generality unites various and even opposite features; 2 the processual nature of reality that is easier to express in the poetical metaphors or abstract principles than in unambiguous conceptual networks; 3 the oppose relationship between being and knowledge, mind and matter, subject and object, self and personality. Entangled in the labyrinth which evade efforts to be conceptually defined, the modern thinking of identity moves towards abandoning the idea of “self” on behalf of the “ego” and towards the misapprehension of identity as being identical. This corresponds to the “time of the lost spirit” stretched between the simultaneous need to find an identity and to give it up.

  12. Identity, identity politics, and neoliberalism

    Wrenn Mary

    2014-01-01

    Full Text Available With the intensification of neoliberalism, it is useful to examine how some individuals might cope with the irrationality of the system. Neoliberalism cloaks the execution of the corporate agenda behind rhetorical manipulation that advocates for limited government. The corollary absence of government involvement on behalf of the citizenry writ large disarms the means of social redress for the individual. Democracy funded and fueled by corporate power thereby disenfranchises the individual, provoking some to search for empowerment through identity politics. The argument set forth suggests that individuals construct, reinforce, or escalate allegiance to identities as a coping mechanism, some of which manifest in violent identity politics.

  3. Temporal Progression of Retinal Progenitor Cell Identity: Implications in Cell Replacement Therapies

    Directory of Open Access Journals (Sweden)

    Awais Javed

    2017-12-01

    Full Text Available Retinal degenerative diseases, which lead to the death of rod and cone photoreceptor cells, are the leading cause of inherited vision loss worldwide. Induced pluripotent or embryonic stem cells (iPSCs/ESCs have been proposed as a possible source of new photoreceptors to restore vision in these conditions. The proof of concept studies carried out in mouse models of retinal degeneration over the past decade have highlighted several limitations for cell replacement in the retina, such as the low efficiency of cone photoreceptor production from stem cell cultures and the poor integration of grafted cells in the host retina. Current protocols to generate photoreceptors from stem cells are largely based on the use of extracellular factors. Although these factors are essential to induce the retinal progenitor cell (RPC fate from iPSCs/ESCs, developmental studies have shown that RPCs alter fate output as a function of time (i.e., their temporal identity to generate the seven major classes of retinal cell types, rather than spatial position. Surprisingly, current stem cell differentiation protocols largely ignore the intrinsic temporal identity of dividing RPCs, which we argue likely explains the low efficiency of cone production in such cultures. In this article, we briefly review the mechanisms regulating temporal identity in RPCs and discuss how they could be exploited to improve cone photoreceptor production for cell replacement therapies.

  4. Blind quantum computation with identity authentication

    Science.gov (United States)

    Li, Qin; Li, Zhulin; Chan, Wai Hong; Zhang, Shengyu; Liu, Chengdong

    2018-04-01

    Blind quantum computation (BQC) allows a client with relatively few quantum resources or poor quantum technologies to delegate his computational problem to a quantum server such that the client's input, output, and algorithm are kept private. However, all existing BQC protocols focus on correctness verification of quantum computation but neglect authentication of participants' identity which probably leads to man-in-the-middle attacks or denial-of-service attacks. In this work, we use quantum identification to overcome such two kinds of attack for BQC, which will be called QI-BQC. We propose two QI-BQC protocols based on a typical single-server BQC protocol and a double-server BQC protocol. The two protocols can ensure both data integrity and mutual identification between participants with the help of a third trusted party (TTP). In addition, an unjammable public channel between a client and a server which is indispensable in previous BQC protocols is unnecessary, although it is required between TTP and each participant at some instant. Furthermore, the method to achieve identity verification in the presented protocols is general and it can be applied to other similar BQC protocols.

  6. An SDN-Based Authentication Mechanism for Securing Neighbor Discovery Protocol in IPv6

    Directory of Open Access Journals (Sweden)

    Yiqin Lu

    2017-01-01

    Full Text Available The Neighbor Discovery Protocol (NDP is one of the main protocols in the Internet Protocol version 6 (IPv6 suite, and it provides many basic functions for the normal operation of IPv6 in a local area network (LAN, such as address autoconfiguration and address resolution. However, it has many vulnerabilities that can be used by malicious nodes to launch attacks, because the NDP messages are easily spoofed without protection. Surrounding this problem, many solutions have been proposed for securing NDP, but these solutions either proposed new protocols that need to be supported by all nodes or built mechanisms that require the cooperation of all nodes, which is inevitable in the traditional distributed networks. Nevertheless, Software-Defined Networking (SDN provides a new perspective to think about protecting NDP. In this paper, we proposed an SDN-based authentication mechanism to verify the identity of NDP packets transmitted in a LAN. Using the centralized control and programmability of SDN, it can effectively prevent the spoofing attacks and other derived attacks based on spoofing. In addition, this mechanism needs no additional protocol supporting or configuration at hosts and routers and does not introduce any dedicated devices.

  8. Identity-Based Authentication for Cloud Computing

    Science.gov (United States)

    Li, Hongwei; Dai, Yuanshun; Tian, Ling; Yang, Haomiao

    Cloud computing is a recently developed new technology for complex systems with massive-scale services sharing among numerous users. Therefore, authentication of both users and services is a significant issue for the trust and security of the cloud computing. SSL Authentication Protocol (SAP), once applied in cloud computing, will become so complicated that users will undergo a heavily loaded point both in computation and communication. This paper, based on the identity-based hierarchical model for cloud computing (IBHMCC) and its corresponding encryption and signature schemes, presented a new identity-based authentication protocol for cloud computing and services. Through simulation testing, it is shown that the authentication protocol is more lightweight and efficient than SAP, specially the more lightweight user side. Such merit of our model with great scalability is very suited to the massive-scale cloud.

    Full Text Available Abstract Background Second-generation drug-eluting stents (DES have raised the bar of clinical performance. These stents are mostly made from cobalt chromium alloy. A newer generation DES has been developed from platinum chromium alloy, but clinical data regarding the efficacy and safety of the platinum chromium-based everolimus-eluting stent (PtCr-EES is limited, with no comparison data against the cobalt chromium-based zotarolimus-eluting stent (CoCr-ZES. In addition, an antiplatelet regimen is an integral component of medical therapy after percutaneous coronary intervention (PCI. A 1-week duration of doubling the dose of clopidogrel (double-dose antiplatelet therapy (DDAT was shown to improve outcome at 1 month compared with conventional dose in acute coronary syndrome (ACS patients undergoing PCI. However in Asia, including Korea, the addition of cilostazol (triplet antiplatelet therapy (TAT is used more commonly than doubling the dose of clopidogrel in high-risk patients. Methods In the 'Harmonizing Optimal Strategy for Treatment of coronary artery stenosis - sAfety & effectiveneSS of drug-elUting stents & antiplatelet REgimen' (HOST-ASSURE trial, approximately 3,750 patients are being prospectively and randomly assigned in a 2 × 2 factorial design according to the type of stent (PtCr-EES vs CoCr-ZES and antiplatelet regimen (TAT vs DDAT. The first primary endpoint is target lesion failure at 1 year for the stent comparison, and the second primary endpoint is net clinical outcome at 1 month for comparison of antiplatelet therapy regimen. Discussion The HOST-ASSURE trial is the largest study yet performed to directly compare the efficacy and safety of the PtCr-EES versus CoCr-ZES in an 'all-comers' population. In addition, this study will also compare the clinical outcome of TAT versus DDAT for 1-month post PCI. Trial registration ClincalTrials.gov number NCT01267734.

    This paper reviews the empirical literature on identity work and identifies two distinct approaches to incorporating emotion. The majority of empirical studies use emotion to describe the experiences of identity work. In doing so, the authors (a) mention the emotions that people feel in situations...... that trigger identity work, (b) illustrate identity work as an emotional endeavour, and (c) describe the emotional impact of successful and unsuccessful identity work. There is also an emerging literature that examines the mutual constitution of emotions and identity work. These authors address emotional...... labour, affective social identification, emotional attachment and detachment, and humour when studying identity work. This paper suggests that, to understand better the relation between emotions and identity work, future research should examine the role of emotions in problematizing identity...

Phys. 40, 2419-2428 (1999)] to the specific identities for trigonometric KdV tau functions. Afterwards, we consider the Fay identity as a functional equation and provide a wide set of solutions of this equation. The main result of this paper is Theorem 3.4, where we generalize the identities from Mishev. An open problem is the transformation of the cubic identities from Mishev to the specific identities for elliptic KdV tau functions

    The design and implementation of a data communications protocol for the Intel Data Base Processor (DBP) is defined. The protocol is termed SPP (Service Port Protocol) since it enables data transfer between the host computer and the DBP service port. The protocol implementation is extensible in that it is explicitly layered and the protocol functionality is hierarchically organized. Extensive trace and performance capabilities have been supplied with the protocol software to permit optional efficient monitoring of the data transfer between the host and the Intel data base processor. Machine independence was considered to be an important attribute during the design and implementation of SPP. The protocol source is fully commented and is included in Appendix A of this report.

    Mancilla, Desla; Moczygemba, Jackie

    2009-09-16

    The crime of medical identity theft is a growing concern in healthcare institutions. A mixed-method study design including a two-stage electronic survey, telephone survey follow-up, and on-site observations was used to evaluate current practices in admitting and registration departments to reduce the occurrence of medical identity theft. Survey participants were chief compliance officers in acute healthcare organizations and members of the Health Care Compliance Association. Study results indicate variance in whether or how patient identity is confirmed in healthcare settings. The findings of this study suggest that information systems need to be designed for more efficient identity management. Admitting and registration staff must be trained, and compliance with medical identity theft policies and procedures must be monitored. Finally, biometric identity management solutions should be considered for stronger patient identification verification.

Using the construction of lesbian, gay, bisexual, and transgender (LGBT identities as an example, it establishes that identity, as it is lived and experienced, is not only multivalent, but also historically contingent. It then raises a number of points regarding the temporal locality of identity—the influence of time on issues of identity and understanding, its implications for legal interventions, social movement building, and paradigms of progressive change. As the title suggests, the paper asks us to consider the frame of identity over time.

    The study of multicultural identity has gained prominence in recent decades and will be even more urgent as the mobility of individuals and social groups becomes the 'new normal'. This paper reviews the state-of-the-art theoretical advancements and empirical discoveries of multicultural identity processes at the intrapersonal, interpersonal, and collective (e.g., organizational, societal) levels. First, biculturalism has more benefits for individuals' psychological and sociocultural adjustment than monoculturalism. Bicultural individuals' racial essentialist beliefs and Bicultural Identity Integration affect cultural frame switching, racial categorization, and creativity. Second, identity denial and identity-based discrimination by other people or groups threaten multicultural individuals' psychological health and performance. Third, multiculturalism and interculturalism policies are associated with different conceptions of and attitudes toward diversity, and have distinct outcomes for multicultural individuals and societies.

This is a rather technical question. In our...... everyday interactions, however, we do raise a number of personal identity questions that are quite distinct from it.

    Full Text Available At the time of globalization it is difficult to pretend avoiding music culture and identity from political, cultural and social developments. Thus, it is impossible for the music to be unshakable and to represent national identity by not taking and giving nothing to culture. The dynamics of life and the rapid development of technology make it impossible for the culture to remain unaffected in terms of sharing experiences social experiences. Culture represents our current course, both in terms of politics, also in the social and human aspects. Through the technology it is possible for our children to be equal with children of all other countries, to exchange information and to connect directly with all countries of the world. Musical education is one of the main factors of cultural development and preservation of national identity. Identity consists of everything we posses and reflect. We are those who distinguish from each other and have a common denominator compared to other nations.

    Identity attribution and enrichment is critical to many aspects of law-enforcement and intelligence gathering; this identity typically spans a number of domains in the natural-world such as biographic information (factual information – e.g. names, addresses), biometric information (e.g. fingerprints) and psychological information. In addition to these natural-world projections of identity, identity elements are projected in the cyber-world. Conversely, undesirable elements may use similar techniques to target individuals for spear-phishing attacks (or worse), and potential targets or their organizations may want to determine how to minimize the attack surface exposed. Our research has been exploring the construction of a mathematical model for identity that supports such holistic identities. The model captures the ways in which an identity is constructed through a combination of data elements (e.g. a username on a forum, an address, a telephone number). Some of these elements may allow new characteristics to be inferred, hence enriching the holistic view of the identity. An example use-case would be the inference of real names from usernames, the ‘path’ created by inferring new elements of identity is highlighted in the ‘critical information’ panel. Individual attribution exercises can be understood as paths through a number of elements. Intuitively the entire realizable ‘capability’ can be modeled as a directed graph, where the elements are nodes and the inferences are represented by links connecting one or more antecedents with a conclusion. The model can be operationalized with two levels of tool support described in this paper, the first is a working prototype, the second is expected to reach prototype by July 2013: Understanding the Model The tool allows a user to easily determine, given a particular set of inferences and attributes, which elements or inferences are of most value to an investigator (or an attacker). The tool is also able to take

  2. Improving an Anonymous and Provably Secure Authentication Protocol for a Mobile User

    2017-01-01

    Full Text Available Recently many authentication protocols using an extended chaotic map were suggested for a mobile user. Many researchers demonstrated that authentication protocol needs to provide key agreement, mutual authentication, and user anonymity between mobile user and server and resilience to many possible attacks. In this paper, we cautiously analyzed chaotic-map-based authentication scheme and proved that it is still insecure to off-line identity guessing, user and server impersonation, and on-line identity guessing attacks. To address these vulnerabilities, we proposed an improved protocol based on an extended chaotic map and a fuzzy extractor. We proved the security of the proposed protocol using a random oracle and AVISPA (Automated Validation of Internet Security Protocols and Applications tool. Furthermore, we present an informal security analysis to make sure that the improved protocol is invulnerable to possible attacks. The proposed protocol is also computationally efficient when compared to other previous protocols.

    The security of key exchange and secure channel protocols, such as TLS, has been studied intensively. However, only few works have considered what happens when the established keys are actually used—to run some protocol securely over the established “channel”. We call this a vertical protocol.......e., that the combination cannot introduce attacks that the individual protocols in isolation do not have. In this work, we prove a composability result in the symbolic model that allows for arbitrary vertical composition (including self-composition). It holds for protocols from any suite of channel and application...

    Full Text Available Emerging developments in communications and computing technology may transform the nature of human identity, in the process rendering obsolete the traditional philosophical and scientific frameworks for understanding the nature of individuals and groups.  Progress toward an evaluation of this possibility and an appropriate conceptual basis for analyzing it may be derived from two very different but ultimately connected social movements that promote this radical change. One is the governmentally supported exploration of Converging Technologies, based in the unification of nanoscience, biology, information science and cognitive science (NBIC. The other is the Transhumanist movement, which has been criticized as excessively radical yet is primarily conducted as a dignified intellectual discussion within a new school of philosophy about human enhancement.  Together, NBIC and Transhumanism suggest the immense transformative power of today’s technologies, through which individuals may explore multiple identities by means of online avatars, semi-autonomous intelligent agents, and other identity expansions.

    Within the background-field framework we present a path integral derivation of the splitting Ward identity for the one-particle irreducible effective action in the presence of an infrared regulator, and make connection with earlier works on the subject. The approach is general in the sense that it does not rely on how the splitting is performed. This identity is then used to address the problem of background dependence of the effective action at an arbitrary energy scale. We next introduce the modified master equation and emphasize its role in constraining the effective action. Finally, application to general gauge theories within the geometric approach is discussed.

  2. Language and Identity Explored

    2016-06-01

    Full Text Available The relationship between language and identity is widely discussed in applied linguistics, sociology, communications and other related scholarly fields. Furthermore, many researchers have focused on the post-Soviet region, which given its unique historical context allows for testing of this relationship. The widespread bilingualism as a result of historical russification and the linguistic transformations that occurred after the collapse of the Soviet Union make the region a ‘sociolinguistic playground’. Recent events in Ukraine have given grounds to further explore this relationship, now in attempt to link language and identity as potential forces for geopolitical change in the region. This paper presents an overview of existing research, theories, and opposing perspectives related to the relationship between language and identity, and considers complications such as historical russification, religious influence, socioeconomic factors, and education with regards to the Ukrainian and post-Soviet context.  I aim to illustrate the significance of language and its effects on socio-political change in the case of Ukraine, by presenting arguments and complications in support of the relationship between language and identity.

    Full Text Available This paper is a continuation of a study on regionalisation and family, within the project named Sociological Aspects of Multiculturality and Regionalisation and their influence on the development of AP Vojvodina and the Republic of Serbia. The author focuses her attention to operationalisation of the theoretical and methodological premises that were developed in the previous paper (Tripković, 2002: 111-127, which means that it represents the results of the second phase of the research plan. This phase includes adjusting of theoretical concepts to the fieldwork displaying the results of the research and the analysis of the findings that put a family in the context of confronting different identities, above all national and regional. As possible "identity difference" was emphasized in the research, theoretical and methodological apparatus was adjusted to this goal. That is why in this paper the replies of interviewees that can suggest or reject the assumption that their national identity can influence significantly the evaluation of identity specificities are presented and analyzed, concerning more or less visible aspects of family life, like welfare status, relations between spouses, respect to the elder, family harmony, number of children, connections with relatives, etc.

    Full Text Available The ambition of this issue of Portal is to reach across the methodological boundaries of history, politics, literature and geography to apply their complementary perspectives to the study of identity and its relation to space and place, an aim that involves attempting to identify the many different ways the notoriously slippery concepts of identity and geography may intersect. For this issue we have selected articles that cast a fresh perspective on two areas where identity and geography intersect: the construction of identity through the imaginative recreation of place in literature: Mapping Literary Spaces; and the study of the shifting relationships of centre and periphery, exclusion and inclusion in urban settings and geopolitical confrontations: Social and Political Peripheries. Gerard Toal has written that geography is not a noun but a verb: it does not describe what space is but studies what we do with space, imaginatively and politically. The articles in this issue illustrate the exercise of the literary and political imagination and the role of materiality and memory in the creation of geographic representation. They show too a new awareness of the centrality of space in the constitution of identities, and the need for a new geocritical reading of its discourse, as the interrelations of place and community are played out on the many scales of social and political life, from the local to the global.   The special issue is organised thus: Introduction Matthew Graves (Aix-Marseille University & Liz Rechniewski (Sydney University: “Imagining Geographies, Mapping Identities.” I.

  15. Rights of Identity

    Directory of Open Access Journals (Sweden)

    Daniel Kofman

    2017-01-01

    Full Text Available A person’s identity is their sense of who and what they are, of who stands in significant relations to them, and of what is valuable to them. This is inevitably very broad, an immediate implication of which is that the concept of identity taken alone cannot do significant normative work. In some cases a person’s identity is bound up with the evil that they do or wish to do, and cannot thereby give them any right to do it. In other cases very powerful elements of a person’s identity – such as their attachment to loved ones – is certainly related to important rights, but it is not entirely clear that one needs the concept of identity to explicate or justify these rights; the deep involvement of their identity is arguably a byproduct of other important values in these cases (such as love, and those values can do the grounding work of the rights by themselves and more simply and clearly. Nevertheless, when suitably qualified, a person’s identity is central to accounting for important political rights. These ranges from rights to participate in cultural practices of one’s group, which sometimes implies duties on governments to support minorities threatened with extinction, to – at the outer limit – rights to arrange political administration. These rights are connected to both autonomy and fairness. Cultural rights are often taken either to be opposed to autonomy, or at best instrumental to personal autonomy (by providing ‘options’, but in fact, the ideal of autonomy, expressed by Mill as being the author of one’s life, requires that one be in control of significant aspects of one’s identity. Significant aspects of one’s identity are collectively determined within a culture. Cultures are not static, and their development is particularly affected by political boundaries. A fundamental right of autonomy implies, therefore, that groups be allowed, within reasonable constraints of general feasibility and stability, to arrange

  16. Host age modulates within-host parasite competition.

    Izhar, Rony; Routtu, Jarkko; Ben-Ami, Frida

    2015-05-01

    In many host populations, one of the most striking differences among hosts is their age. While parasite prevalence differences in relation to host age are well known, little is known on how host age impacts ecological and evolutionary dynamics of diseases. Using two clones of the water flea Daphnia magna and two clones of its bacterial parasite Pasteuria ramosa, we examined how host age at exposure influences within-host parasite competition and virulence. We found that multiply-exposed hosts were more susceptible to infection and suffered higher mortality than singly-exposed hosts. Hosts oldest at exposure were least often infected and vice versa. Furthermore, we found that in young multiply-exposed hosts competition was weak, allowing coexistence and transmission of both parasite clones, whereas in older multiply-exposed hosts competitive exclusion was observed. Thus, age-dependent parasite exposure and host demography (age structure) could together play an important role in mediating parasite evolution. At the individual level, our results demonstrate a previously unnoticed interaction of the host's immune system with host age, suggesting that the specificity of immune function changes as hosts mature. Therefore, evolutionary models of parasite virulence might benefit from incorporating age-dependent epidemiological parameters. © 2015 The Author(s) Published by the Royal Society.

    Institute of Scientific and Technical Information of China (English)

    LI Xinghua; MA Jianfeng; SangJae Moon

    2005-01-01

    The Canetti-Krawczyk (CK) model is a formalism for the analysis of keyexchange protocols, which can guarantee many security properties for the protocols proved secure by this model. But we find this model lacks the ability to guarantee key generation center (KGC) forward secrecy, which is an important security property for key-agreement protocols based on Identity. The essential reason leading to this weakness is that it does not fully consider the attacker's capabilities. In this paper, the CK model is accordingly extended with a new additional attacker's capability of the KGC corruption in Identity-based systems, which enables it to support KGC forward secrecy.

  1. A Federated Digital Identity Management Approach for Business Processes

    Science.gov (United States)

    Bertino, Elisa; Ferrini, Rodolfo; Musci, Andrea; Paci, Federica; Steuer, Kevin J.

    Business processes have gained a lot of attention because of the pressing need for integrating existing resources and services to better fulfill customer needs. A key feature of business processes is that they are built from composable services, referred to as component services, that may belong to different domains. In such a context, flexible multi-domain identity management solutions are crucial for increased security and user-convenience. In particular, it is important that during the execution of a business process the component services be able to verify the identity of the client to check that it has the required permissions for accessing the services. To address the problem of multi-domain identity management, we propose a multi-factor identity attribute verification protocol for business processes that assures clients privacy and handles naming heterogeneity.

    Over the past few years, Session Initiation Protocol (SIP) is found as a substantial application-layer protocol for the multimedia services. It is extensively used for managing, altering, terminating and distributing the multimedia sessions. Authentication plays a pivotal role in SIP environment. Currently, Lu et al. presented an authentication protocol for SIP and profess that newly proposed protocol is protected against all the familiar attacks. However, the detailed analysis describes that the Lu et al.'s protocol is exposed against server masquerading attack and user's masquerading attack. Moreover, it also fails to protect the user's identity as well as it possesses incorrect login and authentication phase. In order to establish a suitable and efficient protocol, having ability to overcome all these discrepancies, a robust ECC-based novel mutual authentication mechanism with anonymity for SIP is presented in this manuscript. The improved protocol contains an explicit parameter for user to cope the issues of security and correctness and is found to be more secure and relatively effective to protect the user's privacy, user's masquerading and server masquerading as it is verified through the comprehensive formal and informal security analysis.

    Full Text Available Pathogens switching to new hosts can result in the emergence of new infectious diseases, and determining which species are likely to be sources of such host shifts is essential to understanding disease threats to both humans and wildlife. However, the factors that determine whether a pathogen can infect a novel host are poorly understood. We have examined the ability of three host-specific RNA-viruses (Drosophila sigma viruses from the family Rhabdoviridae to persist and replicate in 51 different species of Drosophilidae. Using a novel analytical approach we found that the host phylogeny could explain most of the variation in viral replication and persistence between different host species. This effect is partly driven by viruses reaching a higher titre in those novel hosts most closely related to the original host. However, there is also a strong effect of host phylogeny that is independent of the distance from the original host, with viral titres being similar in groups of related hosts. Most of this effect could be explained by variation in general susceptibility to all three sigma viruses, as there is a strong phylogenetic correlation in the titres of the three viruses. These results suggest that the source of new emerging diseases may often be predictable from the host phylogeny, but that the effect may be more complex than simply causing most host shifts to occur between closely related hosts.

    Willetts, Georgina; Clarke, David

    2014-04-01

    The profession of nursing continues to struggle with defining and clarifying its professional identity. The definitive recognition of nursing as a profession was the moving of training from the hospital apprentice model to the tertiary sector. However, this is only part of the story of professional identity in nursing. Once training finishes and enculturation into the workplace commences, professional identity becomes a complicated social activity. This paper proposes social identity theory as a valuable research framework to assist with clarifying and describing the professional identity of nurses. The paper outlines the key elements of a profession and then goes on to describe the main concepts of social identity theory. Lastly, a connection is made between the usefulness of using social identity theory in researching professional identity in nursing, recognizing the contextual nature of the social activity of the profession within its workplace environment. © 2013 Wiley Publishing Asia Pty Ltd.

    Full Text Available Literature can represent, on the one hand, the establishment of cultural and national identity, and, on the other hand, a constant indicator of the differences. Self-image and the image of the Other in literature is very important not only for understanding national character and preservation of cultural identity, but also for the release from ideological reading and stereotyping. Analyzing the image of the Other, research into the representation of the Balkans symbolically represents in the popular literature of the West, study of the cultural context and the processes that formed the writer’s perceptions that determine the establishment of stereotypes about Homo Balcanicus and many others, are all important tasks of imagological research, as well as the key research tasks conducted nowadays. In this paper we shall discuss some of these issues in the field of comparative literature.

    Full Text Available The article discusses the role of historical narratives in the formation of identity. Rüsen’s thesis on the contradiction of traditional historical identities that suggest an ethnocentric position with the processes of intercultural communication is analyzed. The potential of historical narratives in overcoming (or restricting ethnocentrism is considered. It is shown that ethnocentrism is constituted by kinds of the configuration of historical writing rather than by a subjective position of historical narrative authors. The types of stories suggest a the way of making history using only the criteria of success and failure in the interpretation of the past; b interpretation of history as teleological continuity; c merely the necessity to justify (to substantiate claims or to discredit something. It is alleged that the realization that the form of historical knowledge constructs, not discovers, can facilitate liberation from referential fallacy on the whole and enslavement by certain kinds of stories in particular. It is concluded that the recognition of the constitutive nature of historical narratives allows being independent from the traditional forms of historical knowledge and traditional ideas about their cultural value. In particular, it allows reconsidering the need to apply historical knowledge when constructing identity.

    Turban, Jack L; Ehrensaft, Diane

    2017-10-26

    Pediatric gender identity has gained increased attention over the past several years in the popular media, political arena, and medical literature. This article reviews terminology in this evolving field, traditional models of gender identity development and their limitations, epidemiology and natural history of cross-gender identification among children and adolescents, co-occurring conditions and behaviors, research into the biological and psychosocial determinants of cross-gender identification, and research into the options regarding and benefits of clinical approaches to gender incongruent youth. Based on a critical review of the extant literature, both theoretical and empirical, that addresses the issue of pediatric gender identity, the authors synthesized what is presently known and what is in need of further research in order to elucidate the developmental trajectory and clinical needs of gender diverse youth. The field of pediatric gender identity has evolved substantially over the past several years. New research suggests that cross-gender identification is prevalent (approximately 1% of youth). These youth suffer disproportionately high rates of anxiety, depression, and suicidality. Although research into the etiology of cross-gender identification is limited, emerging data have shown that affirmative treatment protocols may improve the high rates of mental health difficulties seen among these patients. The field of pediatric gender identity has evolved dramatically. Emerging data suggest that these patients' high rates of anxiety, depression, and suicidality appear to be improved with affirmative protocols, although future longitudinal data are needed. © 2017 Association for Child and Adolescent Mental Health.

    2011-06-01

    This study investigated the proposition that adolescence involves significant shifts in social identity as a function of changes in social context and cognitive style. Using an experimental design, we primed either peer or gender identity with a sample of 380 early- (12-13 years), mid- (15-16 years), and late-adolescents (18-20 years) and then measured the effect of the prime on self-stereotyping and ingroup favouritism. The findings showed significant differences in social identity across adolescent groups, in that social identity effects were relatively strong in early- and late-adolescents, particularly when peer group identity rather than gender identity was salient. While these effects were consistent with the experience of change in educational social context, differences in cognitive style were only weakly related to ingroup favouritism. The implications of the findings for theory and future research on social identity during adolescence are discussed. Crown Copyright © 2010. Published by Elsevier Ltd. All rights reserved.

    Science.gov (United States)

    Morris, Michael W; Carranza, Erica; Fox, Craig R

    2008-11-01

    Four studies investigated whether activating a social identity can lead group members to choose options that are labeled in words associated with that identity. When political identities were made salient, Republicans (but not Democrats) became more likely to choose the gamble or investment option labeled "conservative." This shift did not occur in a condition in which the same options were unlabeled. Thus, the mechanism underlying the effect appears to be not activated identity-related values prioritizing low risk, but rather activated identity-related language (the group label "conservative"). Indeed, when political identities were salient, Republicans favored options labeled "conservative" regardless of whether the options were low or high risk. Finally, requiring participants to explain the label "conservative" before making their choice did not diminish the effect, which suggests that it does not merely reflect inattention to content or construct accessibility. We discuss the implications of these results for the literatures on identity, priming, choice, politics, and marketing.

    2018-05-14

    The Internet of Things (IoT) introduces many new challenges which cannot be solved using traditional cloud and host computing models. A new architecture known as fog computing is emerging to address these technological and security gaps. Traditional security paradigms focused on providing perimeter-based protections and client/server point to point protocols (e.g., Transport Layer Security (TLS)) are no longer the best choices for addressing new security challenges in fog computing end devices, where energy and computational resources are limited. In this paper, we present a lightweight secure streaming protocol for the fog computing "Fog Node-End Device" layer. This protocol is lightweight, connectionless, supports broadcast and multicast operations, and is able to provide data source authentication, data integrity, and confidentiality. The protocol is based on simple and energy efficient cryptographic methods, such as Hash Message Authentication Codes (HMAC) and symmetrical ciphers, and uses modified User Datagram Protocol (UDP) packets to embed authentication data into streaming data. Data redundancy could be added to improve reliability in lossy networks. The experimental results summarized in this paper confirm that the proposed method efficiently uses energy and computational resources and at the same time provides security properties on par with the Datagram TLS (DTLS) standard.

    Berzonsky, M D

    1992-12-01

    This study examined the relationship between identity style and strategies used to cope with stressors that potentially threaten one's sense of identity. Identity style refers to differences in the way individuals construct and revise or maintain their sense of identity. An informational style involves actively seeking out, evaluating, and utilizing self-relevant information. A normative style highlights the expectations and standards of significant others. A diffuse/avoidant style is characterized by procrastination and situation-specific reactions. Late-adolescent college subjects were administered measures of identity style, ways of coping with academic stressors, and test anxiety. Within this self-as-student context, subjects with diffuse and normative identity styles employed avoidant-oriented coping strategies (wishful thinking, distancing, and tension reduction). An informational style was associated with deliberate, problem-focused coping. Findings are discussed in terms of a process model of identity development.

    The paper discusses the concept of identity in relation to management. We take our starting point in Wittgenstein’s concept language games. We argue that identity is a question of using linguistic tools to construct reality. Two elements of the language game metaphor are central here: rules...... and family resemblance. As such, managing identity in organizations is closely linked to rules and family resemblance. Organizations manage identity through the definition of norms and values for right or wrong, appropriate or inappropriate, to name but a few. Norms and values are important as reference...... points for constructing identities. Managing identity has become more important because the rules-of-the-game have become more unstable. Managing identity is important if the bonds between individuals and organizations are to be sustained. But this task is contradictory and paradoxical of its very nature...

Despite many technical proposals for creating and managing online identities, none has received widespread acceptance. Design and implementation of online identities that are socially acceptable on the Internet remains an open problem. This chapter discusses the interplay between online identities and social networking. Online social networks (OSNs) are growing at a rapid pace and has millions of members in them. While the recent trend is to create explicit OSNs such as Facebook and MySpace, we also have implicit OSNs such as interaction graphs created by email and instant messaging services. Explicit OSNs allow users to create profiles and use them to project their identities on the web. There are many interesting identity related issues in the context of social networking including how OSNs help and hinder the definition of online identities.

    Full Text Available The current dramatic increase of antibiotic resistant bacteria has revitalised the interest in bacteriophages as alternative antibacterial treatment. Meanwhile, the development of bioinformatics methods for analysing genomic data places high-throughput approaches for phage characterization within reach. Here, we present HostPhinder, a tool aimed at predicting the bacterial host of phages by examining the phage genome sequence. Using a reference database of 2196 phages with known hosts, HostPhinder predicts the host species of a query phage as the host of the most genomically similar reference phages. As a measure of genomic similarity the number of co-occurring k-mers (DNA sequences of length k is used. Using an independent evaluation set, HostPhinder was able to correctly predict host genus and species for 81% and 74% of the phages respectively, giving predictions for more phages than BLAST and significantly outperforming BLAST on phages for which both had predictions. HostPhinder predictions on phage draft genomes from the INTESTI phage cocktail corresponded well with the advertised targets of the cocktail. Our study indicates that for most phages genomic similarity correlates well with related bacterial hosts. HostPhinder is available as an interactive web service [1] and as a stand alone download from the Docker registry [2].

    Wireless mesh networks (WMNs) can act as a scalable backbone by connecting separate sensor networks and even by connecting WMNs to a wired network. The Hybrid Wireless Mesh Protocol (HWMP) is the default routing protocol for the 802.11s WMN. The routing protocol is one of the most important parts of the network, and it requires protection, especially in the wireless environment. The existing security protocols, such as the Broadcast Integrity Protocol (BIP), Counter with cipher block chaining message authentication code protocol (CCMP), Secure Hybrid Wireless Mesh Protocol (SHWMP), Identity Based Cryptography HWMP (IBC-HWMP), Elliptic Curve Digital Signature Algorithm HWMP (ECDSA-HWMP), and Watchdog-HWMP aim to protect the HWMP frames. In this paper, we have analyzed the vulnerabilities of the HWMP and developed security requirements to protect these identified vulnerabilities. We applied the security requirements to analyze the existing secure schemes for HWMP. The results of our analysis indicate that none of these protocols is able to satisfy all of the security requirements. We also present a quantitative complexity comparison among the protocols and an example of a security scheme for HWMP to demonstrate how the result of our research can be utilized. Our research results thus provide a tool for designing secure schemes for the HWMP.

    Adipose-derived mesenchymal stem cells (ADMSCs) are an ideal population for regenerative medical application. Both the isolation procedure and the culturing conditions are crucial steps, since low yield can limit further cell therapies, especially when minimal adipose tissue harvests are available for cell expansion. To date, a standardized procedure encompassing both isolation sites and expansion methods is missing, thus making the choice of the most appropriate conditions for the preparation of ADMSCs controversial, especially in view of the different applications needed. In this study, we compared the effects of three different commercial media (DMEM, aMEM, and EGM2), routinely used for ADMSCs expansion, and two supplements, FBS and human platelet lysate, recently proven to be an effective alternative to prevent xenogeneic antibody transfer and immune alloresponse in the host. Notably, all the conditions resulted in being safe for ADMSCs isolation and expansion with platelet lysate supplementation giving the highest isolation and proliferation rates, together with a commitment for osteogenic lineage. Then, we proved that the high ADMSC hematopoietic supportive potential is performed through a constant and abundant secretion of both GCSF and SCF. In conclusion, this study further expands the knowledge on ADMSCs, defining their identity definition and offers potential options for in vitro protocols for clinical production, especially related to HSC expansion without use of exogenous cytokines or genetic modifications.

    The deleterious and sometimes fatal outcomes of bacterial infectious diseases are the net result of the interactions between the pathogen and the host, and the genetically tractable fruit fly, Drosophila melanogaster, has emerged as a valuable tool for modeling the pathogen–host interactions of a wide variety of bacteria. These studies have revealed that there is a remarkable conservation of bacterial pathogenesis and host defence mechanisms between higher host organisms and Drosophila. This review presents an in-depth discussion of the Drosophila immune response, the Drosophila killing model, and the use of the model to examine bacterial–host interactions. The recent introduction of the Drosophila model into the oral microbiology field is discussed, specifically the use of the model to examine Porphyromonas gingivalis–host interactions, and finally the potential uses of this powerful model system to further elucidate oral bacterial-host interactions are addressed.

    Full Text Available Orientation: This study explored strategies for identity work that are central to the negotiation and regulation of employee work identity.Research purpose: The main aim of this study was to explore employee narratives and identify the strategies available to them in the process of identity work, as they defined themselves at work.Motivation for the study: As there is a scarcity of research on identity work in South Africa, this study wanted to advance knowledge about identity work and the strategies used for regulating and negotiating an identity at work by exploring these constructs in this context.Research design, approach and method: A qualitative research process formed the basis for this study. Nineteen employees from a global manufacturing company participated in two semi-structured in-depth interviews. Grounded theory was applied to analyse and interpret the data.Main findings: Nine strategies for identity work were identified and categorised into four broad themes (personal philosophies; relationships; career management and negotiating balance.Practical/managerial implications: Employees followed various strategies for defining themselves at work and this may have some implications for employee work engagement and productivity.Contribution/value-add: This study expands on current theoretical knowledge of identity work, and provides insights into the strategies people use to regulate and negotiate their identities at work.

    There is extensive evidence that social identities can shape people's attitudes and behavior, but what about sensory judgments? We examined the possibility that social identity concerns may also shape the judgment of non-social properties-namely, olfactory judgment. In two experiments, we presented Swiss and non-Swiss participants with the odor of chocolate, for which Switzerland is world-famous, and a control odor (popcorn). Swiss participants primed with Swiss identity reported the odor of chocolate (but not popcorn) as more intense than non-Swiss participants (Experiments 1 and 2) and than Swiss participants primed with individual identity or not primed (Experiment 2). The self-reported intensity of chocolate smell tended to increase as identity accessibility increased-but only among Swiss participants (Experiment 1). These results suggest that identity priming can counter-act classic sensory habituation effects, allowing identity-relevant smells to maintain their intensity after repeated presentations. This suggests that social identity dynamically influences sensory judgment. We discuss the potential implications for models of social identity and chemosensory perception.

  10. Host genetics affect microbial ecosystems via host immunity.

    Genetic evolution of multicellular organisms has occurred in response to environmental challenges, including competition for nutrients, climate change, physical and chemical stressors, and pathogens. However, fitness of an organism is dependent not only on defense efficacy, but also on the ability to take advantage of symbiotic organisms. Indeed, microbes not only encompass pathogenicity, but also enable efficient nutrient uptake from diets nondegradable by the host itself. Moreover, microbes play important roles in the development of host immunity. Here we review associations between specific host genes and variance in microbiota composition and compare with interactions between microbes and host immunity. Recent genome-wide association studies reveal that symbiosis between host and microbiota is the exquisite result of genetic coevolution. Moreover, a subset of microbes from human and mouse microbiota have been identified to interact with humoral and cellular immunity. Interestingly, microbes associated with both host genetics and host immunity are taxonomically related. Most involved are Bifidobacterium, Lactobacillus, and Akkermansia, which are dually associated with both host immunity and host genetics. We conclude that future therapeutics targeting microbiota in the context of chronic inflammatory diseases need to consider both immune and genetic host features associated with microbiota homeostasis.

  11. Nostalgia and lost identity.

    Nostalgia for the Soviet Union is a major social phenomenon in Russia today due to the irrevocable losses of the recent past in which Soviet citizens involuntarily became immigrants in their own country. With reference to discussions of nostalgia in philosophical and psychoanalytic literature, I suggest that nostalgia may represent either a defensive regression to the past or a progressive striving for wholeness through re-connecting with what has been lost in the service of a greater integration. I compare this with the processes of adaptation seen in immigrants and provide a clinical illustration of a young man coming to terms with loss and change in the post-Soviet era. When nostalgia is recognized as a legitimate emotional experience it may facilitate mourning and enable the integration of the past with the present and the development of a new identity. © 2013, The Society of Analytical Psychology.

  14. Creation, Identity and Reflection

    2015-05-01

    Full Text Available The paper “Creation, Identity and Reflection” approaches the identification in the “mirror” of reality with creation, in other words seeking the authors’ identity in the reflected images. Reflection means attempting to find oneself, the mirror being the main principle of creation. Many characters become interesting only when they step into the world beyond the mirror, when their faces are doubled by the other self or when their selves are returned by other characters. The narcissistic concept of the mirror, i.e. the reflection in the mirror and the representation of the mirror itself, is a recurrent one in literature, but the reflection of the self which is not the self (as it is a reflection does not necessarily appear in a mirror or in a photograph or portrait. Sometimes, the not-self is returned to the self by another person or character. As far as Oscar Wilde’s theories are concerned, the main idea is that people are interesting for their masks, not for their inner nature. What Wilde calls “inner nature” is the characters’ un-reflected self and the mask is the reflection, the self in the mirror. Some characters’ relationships develop within a fiction that they dramatically try to preserve and protect with the risk of suffering. They refuse to take off the masks which define them in the others’ minds and hearts; the narcissistic individuals (both artists and characters seek and love their own image which they project upon facts, thus creating a fictive realm.

    This study provided a descriptive and quantitative comparative analysis of data from an assessment protocol for adolescents referred clinically for gender identity disorder (n = 192; 105 boys, 87 girls) or transvestic fetishism (n = 137, all boys). The protocol included information on demographics, behavior problems, and psychosexual measures. Gender identity disorder and transvestic fetishism youth had high rates of general behavior problems and poor peer relations. On the psychosexual measures, gender identity disorder patients had considerably greater cross-gender behavior and gender dysphoria than did transvestic fetishism youth and other control youth. Male gender identity disorder patients classified as having a nonhomosexual sexual orientation (in relation to birth sex) reported more indicators of transvestic fetishism than did male gender identity disorder patients classified as having a homosexual sexual orientation (in relation to birth sex). The percentage of transvestic fetishism youth and male gender identity disorder patients with a nonhomosexual sexual orientation self-reported similar degrees of behaviors pertaining to transvestic fetishism. Last, male and female gender identity disorder patients with a homosexual sexual orientation had more recalled cross-gender behavior during childhood and more concurrent cross-gender behavior and gender dysphoria than did patients with a nonhomosexual sexual orientation. The authors discuss the clinical utility of their assessment protocol.

    Males and females differ in many ways and might present different opportunities and challenges to their parasites. In the same way that parasites adapt to the most common host type, they may adapt to the characteristics of the host sex they encounter most often. To explore this hypothesis, we characterized host sex-specific effects of the parasite Pasteuria ramosa, a bacterium evolving in naturally, strongly, female-biased populations of its host Daphnia magna. We show that the parasite proliferates more successfully in female hosts than in male hosts, even though males and females are genetically identical. In addition, when exposure occurred when hosts expressed a sexual dimorphism, females were more infected. In both host sexes, the parasite causes a similar reduction in longevity and leads to some level of castration. However, only in females does parasite-induced castration result in the gigantism that increases the carrying capacity for the proliferating parasite. We show that mature male and female Daphnia represent different environments and reveal one parasite-induced symptom (host castration), which leads to increased carrying capacity for parasite proliferation in female but not male hosts. We propose that parasite induced host castration is a property of parasites that evolved as an adaptation to specifically exploit female hosts.

    2016-03-04

    The Fermi National Accelerator Laboratory (FNAL) is facing the challenge of providing scientific data access and grid submission to scientific collaborations that span the globe but are hosted at FNAL. Users in these collaborations are currently required to register as an FNAL user and obtain FNAL credentials to access grid resources to perform their scientific computations. These requirements burden researchers with managing additional authentication credentials, and put additional load on FNAL for managing user identities. Our design integrates the existing InCommon federated identity infrastructure, CILogon Basic CA, and MyProxy with the FNAL grid submission system to provide secure access for users from diverse experiments and collab orations without requiring each user to have authentication credentials from FNAL. The design automates the handling of certificates so users do not need to manage them manually. Although the initial implementation is for FNAL's grid submission system, the design and the core of the implementation are general and could be applied to other distributed computing systems.

  14. Host Factors in Ebola Infection.

    2016-08-31

    Ebola virus (EBOV) emerged in West Africa in 2014 to devastating effect, and demonstrated that infection can cause a broad range of severe disease manifestations. As the virus itself was genetically similar to other Zaire ebolaviruses, the spectrum of pathology likely resulted from variable responses to infection in a large and genetically diverse population. This review comprehensively summarizes current knowledge of the host response to EBOV infection, including pathways hijacked by the virus to facilitate replication, host processes that contribute directly to pathogenesis, and host-pathogen interactions involved in subverting or antagonizing host antiviral immunity.

    This article is part of a Special Issue "Puberty and Adolescence".This article aims to provide an outline of what is currently known on trajectories, and contributing factors to gender identity development in adolescence. We give a historical overview of the concept of gender identity, and describe general identity development in adolescence, gender identity development in the general population and in gender variant youth. Possible psychosocial (such as child and parental characteristics) and biological factors (such as the effects of prenatal exposure to gonadal hormones and the role of genetics) contributing to a gender variant identity are discussed. Studies focusing on a number of psychosocial and biological factors separately, indicate that each of these factors influence gender identity formation, but little is known about the complex interplay between the factors, nor about the way individuals themselves contribute to the process. Research into normative and gender variant identity development of adolescents is clearly lagging behind. However, studies on persons with gender dysphoria and disorders of sex development, show that the period of adolescence, with its changing social environment and the onset of physical puberty, seems to be crucial for the development of a non-normative gender identity.

  4. STORYTELLING AND UNIVERSITY BRANDING IDENTITY

    2016-08-01

    Full Text Available The present article sets out to clarify the concepts of storytelling and branding, with a focus on university branding and visual identity – the latter being a vital element to a brand’s uniqueness. Storytelling is an important method of brand construction, and it entails a strong power of seduction. Branding is increasingly more about storytelling. Practically, a story is an image made up of facts, feelings and interpretations, which are often told to us solely by the university itself. As such, the brand appears on the market accompanied by its identity. Identity is what we aim to express with help of the brand. Implementing a system of visual identity that would help to harmoniously develop a university brand requires a handbook of visual identity. The present article aims to be a starting point for such a handbook serving the University of Bucharest, which currently does not own such a handbook

    Full Text Available The aim of this article is to understand the relationship between ethnic identity, victimization/witnessing community violence, ethnic discrimination, and aggression in a sample of university students living in the South East Region of Turkey. The participants were 263 university students of predominantly Kurdish ethnic origin. The results showed that males had higher levels of ethnic identity in the dimensions of exploration and commitment. Males also presented higher scores for witnessing community violence and lifetime exposure to ethnic discrimination. The most important predictor of participants’ ethnic identity was witnessing community violence. Participants who witnessed violent acts in their social environment had higher ethnic identity levels. Although the predictor variables could not explain an important part of the participants’ aggression levels, only perceived ethnic discrimination was positively related to aggressive behavior. The role of native language efficiency in ethnic identity is also discussed.

  6. HOST liner cyclic facilities

    Schultz, D.

    1983-01-01

    The HOST Liner Cyclic Program is utilizing two types of test apparatus, rectangular box rigs and a full annular rig. To date two quartz lamp cyclic box rigs have been tested and a third is to begin testing in late October 1983. The box rigs are used to evaluate 5x8 inch rectangular linear samples. A 21 inch diameter outer liner simulator is also being built up for testing beginning in April 1984. All rigs are atmospheric rigs. The first box rig, a three 6-kVA lamp installation, was operated under adverse conditions to determine feasibility of using quartz lamps for cyclic testing. This work was done in December 1981 and looked promising. The second box rig, again using three 6-kVA lamps, was operated to obtain instrumentation durability information and initial data input to a Finite Element Model. This limited test program was conducted in August 1983. Five test plates were run. Instrumentation consisted of strain gages, thermocouples and thermal paint. The strain gages were found to fail at 1200 F as expected though plates were heated to 1700 F. The third box rig, containing four 6-kVA lamps, is in build up for testing to begin in late October 1983. In addition to 33 percent greater power input, this rig has provision for 400 F backside line cooling air and a viewing port suitable for IR camera viewing. The casing is also water cooled for extended durability.

  7. [Tuberculosis in compromised hosts].

    2003-11-01

    Recent development of tuberculosis in Japan tends to converge on a specific high risk group. The proportion of tuberculosis developing particularly from the compromised hosts in the high risk group is especially high. At this symposium, therefore, we took up diabetes mellitus, gastrectomy, dialysis, AIDS and the elderly for discussion. Many new findings and useful reports for practical medical treatment are submitted; why these compromised hosts are predisposed to tuberculosis, tuberculosis diagnostic and remedial notes of those compromised hosts etc. It is an important question for the future to study how to prevent tuberculosis from these compromised hosts. 1. Tuberculosis in diabetes mellitus: aggravation and its immunological mechanism: Kazuyoshi KAWAKAMI (Department of Internal Medicine, Division of Infectious Diseases, Graduate School and Faculty of Medicine, University of the Ryukyus). It has been well documented that diabetes mellitus (DM) is a major aggravating factor in tuberculosis. The onset of this disease is more frequent in DM patients than in individuals with any underlying diseases. However, the precise mechanism of this finding remains to be fully understood. Earlier studies reported that the migration, phagocytosis and bactericidal activity of neutrophils are all impaired in DM patients, which is related to their reduced host defense to infection with extracellular bacteria, such as S. aureus and E. colli. Host defense to mycobacterial infection is largely mediated by cellular immunity, and Th1-related cytokines, such as IFN-gamma and IL-12, play a central role in this response. It is reported that serum level of these cytokines and their production by peripheral blood mononuclear cells (PBMC) are reduced in tuberculosis patients with DM, and this is supposed to be involved in the high incidence of tuberculosis in DM. Our study observed similar findings and furthermore indicated that IFN-gamma and IL-12 production by BCG-stimulated PBMC was lower

    Research purpose: The main aim of this study was to explore employee narratives and identify the strategies available to them in the process of identity work, as they defined themselves at work. Motivation for the study: As there is a scarcity of research on identity work in South Africa, this study wanted to advance knowledge about identity work and the strategies used for regulating and negotiating an identity at work by exploring these constructs in this context. Research design, approach and method: A qualitative research process formed the basis for this study. Nineteen employees from a global manufacturing company participated in two semi-structured in-depth interviews. Grounded theory was applied to analyse and interpret the data. Main findings: Nine strategies for identity work were identified and categorised into four broad themes (personal philosophies; relationships; career management and negotiating balance. Practical/managerial implications: Employees followed various strategies for defining themselves at work and this may have some implications for employee work engagement and productivity. Contribution/value-add: This study expands on current theoretical knowledge of identity work, and provides insights into the strategies people use to regulate and negotiate their identities at work.

  9. Quantum broadcast communication and authentication protocol with a quantum one-time pad

    2014-01-01

    A quantum broadcast communication and authentication protocol with a quantum one-time pad based on the Greenberger—Horne—Zeilinger state is proposed. A binary string is used to express the identity of the receiver, which is encoded as a single sequence of photons. The encoded photon sequence acts as a detection sequence and implements authentication. An XOR operation serves as a one-time pad and is used to ensure the security of the protocol. The binary string is reused even in a noisy channel and proves to be unconditionally secure. In contrast with the protocols proposed by Wang et al. [Chin. Phys. 16 1868 (2007)] and Yang et al. [Chin. Phys. B 19 070304 (2010)], the protocol in this study implements the identity authentication with a reusable binary string; no hash function or local unitary operation is used. The protocol in this study is also easier to implement and highly efficient without losing security. (general)

  10. Gender identity disorder.

    2006-05-01

    Gender Identity Disorder (GID) is a relatively rare condition of atypical gender development in which there is a psychological perception of self as masculine or feminine which is incongruent with ones phenotype. GID replaced the term Transsexualism in DSM-IV in 1994. The demographics of GID in Ireland have not been established. Since 2000 we have received 52 referrals of individuals with confirmed GID to our endocrine service for consideration for hormonal treatment (HT). Of the 52 patients 45 have male to female (MTF) GID (mean age 38.9 years) and 7 have female to male (FTM) GID (mean age 30.7 years). The age at presentation in this group is approximately 9 years older than in international series for both MTF (39 years v 30yrs) and FTM (31 yrs v 22yrs). The karyotype where analysed has been normal for their phenotypic sex. Twenty-three of the patients had received HT prior to attending our clinic that in only one case had been prescribed by a specialist. A number of patients had obtained HT via the internet or from overseas sources without medical review. Eighteen of the patients have been or are married and 14 of the group have children. The scale of referrals confirms that GID exists in the Irish population to a significant degree. Thus an appropriate care pathway for people with the condition needs to be established. This will facilitate optimum medical management of the patient group and a coherent approach to the many difficult social issues faced individuals with this disorder.

    Body Integrity Identity Disorder (BIID) is a rare, infrequently studied and highly secretive condition in which there is a mismatch between the mental body image and the physical body. Subjects suffering from BIID have an intense desire to amputate a major limb or severe the spinal cord in order to become paralyzed. Aim of the study is to broaden the knowledge of BIID amongst medical professionals, by describing all who deal with BIID. Somatic, psychiatric and BIID characteristic data were collected from 54 BIID individuals using a detailed questionnaire. Subsequently, data of different subtypes of BIID (i.e. wish for amputation or paralyzation) were evaluated. Finally, disruption in work, social and family life due to BIID in subjects with and without amputation were compared. Based on the subjects' reports we found that BIID has an onset in early childhood. The main rationale given for their desire for body modification is to feel complete or to feel satisfied inside. Somatic and severe psychiatric co-morbidity is unusual, but depressive symptoms and mood disorders can be present, possibly secondary to the enormous distress BIID puts upon a person. Amputation and paralyzation variant do not differ in any clinical variable. Surgery is found helpful in all subjects who underwent amputation and those subjects score significantly lower on a disability scale than BIID subjects without body modification. The amputation variant and paralyzation variant of BIID are to be considered as one of the same condition. Amputation of the healthy body part appears to result in remission of BIID and an impressive improvement of quality of life. Knowledge of and respect for the desires of BIID individuals are the first steps in providing care and may decrease the huge burden they experience.

    2008-10-01

    Sexuality is generally considered an important aspect of self-hood. Therefore, individuals who do not experience sexual attraction, and embrace an asexual identity are in a unique position to inform the social construction of sexuality. This study explores the experiences of asexual individuals utilizing open ended Internet survey data from 102 self-identified asexual people. In this paper I describe several distinct aspects of asexual identities: the meanings of sexual, and therefore, asexual behaviors, essentialist characterizations of asexuality, and lastly, interest in romance as a distinct dimension of sexuality. These findings have implications not only for asexual identities, but also for the connections of asexuality with other marginalized sexualities.

    Full Text Available The verse of holy Koran "verily the most honored of you in the sight of Allah is [he who is] the most virtuous of you" directly shows that in god's willing there is no superiority of a man or a group than others except those who have piety to god. In fact, the Islamic identity focuses on the superiority of piety among humans and does not focus on superiority of a man or a group that causes Islamic identity theoretically be against other competitive identities such as ethnic, global and national identity. Therefore, this research aims to study the relationship between Islamic identity and competitive identities (ethnic, national and global. In this way based on Sheldon Stryker theory and survey method, 431 students have elected and have analyzed. The results have shown that there was positive significant relationship between Islamic identity, national and ethnic identity, and negative significant relationship between Islamic identity and global identity. In addition, multivariate regression results have shown that the variables national and global identities have explained 45 percent of the variation of Islamic identity variable. The results shows that national and ethnic identity amplify the Islamic identity and they have positive relationship with it and in fact they are not a competitive identity for Islamic identity but global identity has negative relationship with Islamic identity and therefore it is a competitive identity for Islamic identity.

    Full Text Available To the problem of many recently proposed RFID authentication protocol was soon find security holes, we analyzed the main reason, which is that protocol design is not rigorous, and the correctness of the protocol cannot be guaranteed. To this end, authentication test method was adopted in the process of the formal analysis and strict proof to the proposed RFID protocol in this paper. Authentication Test is a new type of analysis and design method of security protocols based on Strand space model, and it can be used for most types of the security protocols. After analysis the security, the proposed protocol can meet the RFID security demand: information confidentiality, data integrity and identity authentication.

    The present publication surveys several applications of in silico (i.e., computational) toxicology approaches across different industries and institutions. It highlights the need to develop standardized protocols when conducting toxicity-related predictions. This contribution articulates the information needed for protocols to support in silico predictions for major toxicological endpoints of concern (e.g., genetic toxicity, carcinogenicity, acute toxicity, reproductive toxicity, developmental toxicity) across several industries and regulatory bodies. Such novel in silico toxicology (IST) protocols, when fully developed and implemented, will ensure in silico toxicological assessments are performed and evaluated in a consistent, reproducible, and well-documented manner across industries and regulatory bodies to support wider uptake and acceptance of the approaches. The development of IST protocols is an initiative developed through a collaboration among an international consortium to reflect the state-of-the-art in in silico toxicology for hazard identification and characterization. A general outline for describing the development of such protocols is included and it is based on in silico predictions and/or available experimental data for a defined series of relevant toxicological effects or mechanisms. The publication presents a novel approach for determining the reliability of in silico predictions alongside experimental data. In addition, we discuss how to determine the level of confidence in the assessment based on the relevance and reliability of the information. Copyright © 2018. Published by Elsevier Inc.

    To evaluate a whole body (WB) continuous-table-movement (CTM) MR protocol for the assessment of multiple myeloma (MM) in comparison to a step-by-step WB protocol. Eighteen patients with MM were examined at 1.5T using a WB CTM protocol (axial T2-w fs BLADE, T1-w GRE sequence) and a step-by-step WB protocol including coronal/sagittal T1-w SE and STIR sequences as reference. Protocol time was assessed. Image quality, artefacts, liver/spleen assessability, and the ability to depict bone marrow lesions less than or greater than 1 cm as well as diffuse infiltration and soft tissue lesions were rated. Potential changes in the Durie and Salmon Plus stage and the detectability of complications were assessed. Mean protocol time was 6:38 min (CTM) compared to 24:32 min (standard). Image quality was comparable. Artefacts were more prominent using the CTM protocol (P = 0.0039). Organ assessability was better using the CTM protocol (P < 0.001). Depiction of bone marrow and soft tissue lesions was identical without a staging shift. Vertebral fractures were not detected using the CTM protocol. The new protocol allows a higher patient throughput and facilitates the depiction of extramedullary lesions. However, as long as vertebral fractures are not detectable, the protocol cannot be safely used for clinical routine without the acquisition of an additional sagittal sequence. (orig.)

An authentication protocol suitable for the considered scenario which jointly employs the learning parity with noise (LPN problem and a paradigm of random selection is proposed. It is shown that the proposed protocol is secure against active attacking scenarios and so called GRS man-in-the-middle (MIM attacking scenarios. In comparison with the related previously reported authentication protocols the proposed one provides reduction of the implementation complexity and at least the same level of the cryptographic security.

    Internet of Things (IoT) is an arrangement of advancements that are between disciplinary. It is utilized to have compelling combination of both physical and computerized things. With IoT physical things can have personal virtual identities and participate in distributed computing. Realization of IoT needs the usage of sensors based on the sector for which IoT is integrated. For instance, in healthcare domain, IoT needs to have integration with wearable sensors used by patients. As sensor devices produce huge amount of data, often called big data, there should be efficient routing protocols in place. To the extent remote systems is worried there are some current protocols, for example, OLSR, DSR and AODV. It additionally tosses light into Trust based routing protocol for low-power and lossy systems (TRPL) for IoT. These are broadly utilized remote directing protocols. As IoT is developing round the corner, it is basic to investigate routing protocols that and evaluate their execution regarding throughput, end to end delay, and directing overhead. The execution experiences can help in settling on very much educated choices while incorporating remote systems with IoT. In this paper, we analyzed different routing protocols and their performance is compared. It is found that AODV showed better performance than other routing protocols aforementioned.

  10. The challenge of plural identity

    2005-01-01

    Full Text Available The complexity of collective existence is expressed through an awareness of its real identity, which then entails an appropriate attitude towards its own negativity. Within the hierarchically structured identity, different levels of its generality make it possible to consider them as factors of a plural reality. If negativity is raised to consciousness, then its dark side is dismantled. Thus, instead of being a factor of conflict, negativity becomes an element of complementariness and a factor in the construction of a shared identity at a higher level of generality.

  12. A Self-Stabilizing Synchronization Protocol for Arbitrary Digraphs

    Malekpour, Mahyar R.

    2011-01-01

    This paper presents a self-stabilizing distributed clock synchronization protocol in the absence of faults in the system. It is focused on the distributed clock synchronization of an arbitrary, non-partitioned digraph ranging from fully connected to 1-connected networks of nodes while allowing for differences in the network elements. This protocol does not rely on assumptions about the initial state of the system, other than the presence of at least one node, and no central clock or a centrally generated signal, pulse, or message is used. Nodes are anonymous, i.e., they do not have unique identities. There is no theoretical limit on the maximum number of participating nodes. The only constraint on the behavior of the node is that the interactions with other nodes are restricted to defined links and interfaces. This protocol deterministically converges within a time bound that is a linear function of the self-stabilization period. We present an outline of a deductive proof of the correctness of the protocol. A bounded model of the protocol was mechanically verified for a variety of topologies. Results of the mechanical proof of the correctness of the protocol are provided. The model checking results have verified the correctness of the protocol as they apply to the networks with unidirectional and bidirectional links. In addition, the results confirm the claims of determinism and linear convergence. As a result, we conjecture that the protocol solves the general case of this problem. We also present several variations of the protocol and discuss that this synchronization protocol is indeed an emergent system.

    When Bacillus subtilis is infected by bacteriophage SPO1, the phage directs the remodeling of the host cell, converting it into a factory for phage reproduction. Much synthesis of host DNA, RNA, and protein is shut off, and cell division is prevented. Here I describe the protocols by which we have demonstrated those processes, and identified the roles played by specific SPO1 gene products in causing those processes.

    On request of the Dutch ministry of Economic Affairs five institutes have collaborated to create a 'Protocol Monitoring Energy Conservation', a common method and database to calculate the amount of energy savings realised in past years. The institutes concerned are the Central Bureau of Statistics (CBS), the Netherlands Bureau for Economic Policy Analysis (CPB), the Energy research Centre of the Netherlands (ECN), the National Agency for Energy and Environment (Novem) and the Netherlands Institute of Public Health and the Environment (RIVM). The institutes have agreed upon a clear definition of energy use and energy savings. The demarcation with renewable energy, the saving effects of substitution between energy carriers and the role of import and export of energy have been elaborated. A decomposition method is used to split up the observed change in energy use in a number of effects, on a national and sectoral level. This method includes an analysis of growth effects, effects of structural changes in production and consumption activities and savings on end use or with more efficient conversion processes. To calculate these effects the total energy use is desegregated as much as possible. For each segment a reference energy use is calculated according to the trend in a variable which is supposed to be representative for the use without savings. The difference with the actual energy use is taken as the savings realised. Results are given for the sectors households, industry, agriculture, services and government, transportation and the energy sector; as well as a national figure. A special feature of the protocol method is the application of primary energy use figures in the determination of savings for end users. This means that the use of each energy carrier is increased with a certain amount, according to the conversion losses caused elsewhere in the energy system. The losses concern the base year energy sector and losses abroad for imports of secondary

    Safeguards instrumentation is increasingly being incorporated into remote monitoring applications. In the past, vendors of radiation monitoring instruments typically provided the tools for uploading the monitoring data to a host. However, the proprietary nature of communication protocols lends itself to increased computer support needs and increased installation expenses. As a result, a working group of suppliers and customers of radiation monitoring instruments defined an open network protocol for transferring packets on a local area network from radiation monitoring equipment to network hosts. The protocol was termed RadNet. While it is now primarily used for health physics instruments, RadNet's flexibility and strength make it ideal for remote monitoring of nuclear materials. The incorporation of standard, open protocols ensures that future work will not render present work obsolete; because RadNet utilizes standard Internet protocols, and is itself a non-proprietary standard. The use of industry standards also simplifies the development and implementation of ancillary services, e.g. E-main generation or even pager systems

    Ebola virus is an enveloped virus with filamentous structure and causes a severe hemorrhagic fever in human and nonhuman primates. Host cell entry is the first essential step in the viral life cycle, which has been extensively studied as one of the therapeutic targets. A virus factor of cell entry is a surface glycoprotein (GP), which is an only essential viral protein in the step, as well as the unique particle structure. The virus also interacts with a lot of host factors to successfully enter host cells. Ebola virus at first binds to cell surface proteins and internalizes into cells, followed by trafficking through endosomal vesicles to intracellular acidic compartments. There, host proteases process GPs, which can interact with an intracellular receptor. Then, under an appropriate circumstance, viral and endosomal membranes are fused, which is enhanced by major structural changes of GPs, to complete host cell entry. Recently the basic research of Ebola virus infection mechanism has markedly progressed, largely contributed by identification of host factors and detailed structural analyses of GPs. This article highlights the mechanism of Ebola virus host cell entry, including recent findings.

    2014-09-01

    Full Text Available Communicating parties inside computer networks use different kind of identifiers. Some of these identifiers are stable, e.g., logins used to access a specific service, some are only temporary, e.g., dynamically assigned IP addresses. This paper tackles several challenges of lawful interception that emerged in modern networks. The main contribution is the graph model that links identities learnt from various sources distributed in a network. The inferred identities result into an interception of more detailed data in conformance with the issued court order. The approach deals with network address translation, short-lived identifiers and simultaneous usage of different identities. The approach was evaluated to be viable during real network testing based on various means to learn identities of users connected to a network.

  1. Human Rights and Cultural Identity

    Directory of Open Access Journals (Sweden)

    John-Stewart Gordon

    2015-12-01

    Full Text Available Universal human rights and particular cultural identities, which are relativistic by nature, seem to stand in conflict with each other. It is commonly suggested that the relativistic natures of cultural identities undermine universal human rights and that human rights might compromise particular cultural identities in a globalised world. This article examines this supposed clash and suggests that it is possible to frame a human rights approach in such a way that it becomes the starting point and constraining framework for all non-deficient cultural identities. In other words, it is possible to depict human rights in a culturally sensitive way so that universal human rights can meet the demands of a moderate version of meta-ethical relativism which acknowledges a small universal core of objectively true or false moral statements and avers that, beyond that small core, all other moral statements are neither objectively true nor false.

  2. Science Identity in Informal Education

    Science.gov (United States)

    Schon, Jennifer A.

    The national drive to increase the number of students pursuing Science Technology, Engineering, and Math (STEM) careers has brought science identity into focus for educators, with the need to determine what encourages students to pursue and persist in STEM careers. Science identity, the degree to which students think someone like them could be a scientist is a potential indicator of students pursuing and persisting in STEM related fields. Science identity, as defined by Carlone and Johnson (2007) consists of three constructs: competence, performance, and recognition. Students need to feel like they are good at science, can perform it well, and that others recognize them for these achievements in order to develop a science identity. These constructs can be bolstered by student visitation to informal education centers. Informal education centers, such as outdoor science schools, museums, and various learning centers can have a positive impact on how students view themselves as scientists by exposing them to novel and unique learning opportunities unavailable in their school. Specifically, the University of Idaho's McCall Outdoor Science School (MOSS) focuses on providing K-12 students with the opportunity to learn about science with a place-based, hands-on, inquiry-based curriculum that hopes to foster science identity development. To understand the constructs that lead to science identity formation and the impact the MOSS program has on science identity development, several questions were explored examining how students define the constructs and if the MOSS program impacted how they rate themselves within each construct. A mixed-method research approach was used consisting of focus group interviews with students and pre, post, one-month posttests for visiting students to look at change in science identity over time. Results from confirmatory factor analysis indicate that the instrument created is a good fit for examining science identity and the associated

    Little, Miles; Paul, Kim; Jordens, Christopher F C; Sayers, Emma-Jane

    2002-01-01

    Personal identity is self-evidently important to us all. Identity is a philosophically complex subject, but there is some agreement that memory, embodiment and continuity are essential components. The sense of memory includes 'future memory', the kind of memory we would like to construct for ourselves as our lives proceed. While the sense of personal identity is internal to the individual, a sense of that person's identity exists in the minds of others. Extreme experiences threaten the element of continuity, because they may bring bodily changes as well as cognitive changes that challenge central values. Restoring or preserving continuity is a major task for survivors. The ways in which people experience discontinuity because of cancer illness, and the ways in which they manage this experience emerges from the narratives of the survivors of cancer and in the narratives of health care workers who look after them. People manage discontinuity by reference to stable 'anchor points' in their beliefs and values; by re-constructing versions of their pre-experience identities, drawing on past memory and finding ways to preserve a continuity between past memory, present experience and constructions of the future; by using the experience to develop established facets of identity; and by imbuing the experience with meaning and recognising the enlarged identity made possible by survival. Those who cannot achieve a sense of continuity may feel alienated from themselves, their friends and family. All these methods of management may be used by one person to negotiate the post-experience identity in its different social interactions. The experience of the survivor can be further understood by recognising the challenge posed by extreme experience to the sense of continuity of both embodied self and memory. A satisfactory discourse of survival has yet to enter the public domain. This lack adds to the burdens of survivors, including those who have survived cancer. Copyright 2002 John

  12. Insights into Host Cell Modulation and Induction of New Cells by the Corn Smut Ustilago maydis

    Directory of Open Access Journals (Sweden)

    Amey Redkar

    2017-05-01

    Full Text Available Many filamentous fungal pathogens induce drastic modulation of host cells causing abnormal infectious structures such as galls, or tumors that arise as a result of re-programming in the original developmental cell fate of a colonized host cell. Developmental consequences occur predominantly with biotrophic phytopathogens. This suggests that these host structures result as an outcome of efficient defense suppression and intimate fungal–host interaction to suit the pathogen’s needs for completion of its infection cycle. This mini-review mainly summarizes host cell re-programming that occurs in the Ustilago maydis – maize interaction, in which the pathogen deploys cell-type specific effector proteins with varying activities. The fungus senses the physiological status and identity of colonized host cells and re-directs the endogenous developmental program of its host. The disturbance of host cell physiology and cell fate leads to novel cell shapes, increased cell size, and/or the number of host cells. We particularly highlight the strategies of U. maydis to induce physiologically varied host organs to form the characteristic tumors in both vegetative and floral parts of maize.

  13. Model Additional Protocol

    International Nuclear Information System (INIS)

    Rockwood, Laura

    2001-01-01

    Since the end of the cold war a series of events has changed the circumstances and requirements of the safeguards system. The discovery of a clandestine nuclear weapons program in Iraq, the continuing difficulty in verifying the initial report of Democratic People's Republic of Korea upon entry into force of their safeguards agreement, and the decision of the South African Government to give up its nuclear weapons program and join the Treaty on the Non-Proliferation of Nuclear Weapons have all played a role in an ambitious effort by IAEA Member States and the Secretariat to strengthen the safeguards system. A major milestone in this effort was reached in May 1997 when the IAEA Board of Governors approved a Model Protocol Additional to Safeguards Agreements. The Model Additional Protocol was negotiated over a period of less than a year by an open-ended committee of the Board involving some 70 Member States and two regional inspectorates. The IAEA is now in the process of negotiating additional protocols, State by State, and implementing them. These additional protocols will provide the IAEA with rights of access to information about all activities related to the use of nuclear material in States with comprehensive safeguards agreements and greatly expanded physical access for IAEA inspectors to confirm or verify this information. In conjunction with this, the IAEA is working on the integration of these measures with those provided for in comprehensive safeguards agreements, with a view to maximizing the effectiveness and efficiency, within available resources, the implementation of safeguards. Details concerning the Model Additional Protocol are given. (author)

  14. Survival relative to new and ancestral host plants, phytoplasma infection, and genetic constitution in host races of a polyphagous insect disease vector

    Science.gov (United States)

    Maixner, Michael; Albert, Andreas; Johannesen, Jes

    2014-01-01

    Dissemination of vectorborne diseases depends strongly on the vector's host range and the pathogen's reservoir range. Because vectors interact with pathogens, the direction and strength of a vector's host shift is vital for understanding epidemiology and is embedded in the framework of ecological specialization. This study investigates survival in host-race evolution of a polyphagous insect disease vector, Hyalesthes obsoletus, whether survival is related to the direction of the host shift (from field bindweed to stinging nettle), the interaction with plant-specific strains of obligate vectored pathogens/symbionts (stolbur phytoplasma), and whether survival is related to genetic differentiation between the host races. We used a twice repeated, identical nested experimental design to study survival of the vector on alternative hosts and relative to infection status. Survival was tested with Kaplan–Meier analyses, while genetic differentiation between vector populations was quantified with microsatellite allele frequencies. We found significant direct effects of host plant (reduced survival on wrong hosts) and sex (males survive longer than females) in both host races and relative effects of host (nettle animals more affected than bindweed animals) and sex (males more affected than females). Survival of bindweed animals was significantly higher on symptomatic than nonsymptomatic field bindweed, but in the second experiment only. Infection potentially had a positive effect on survival in nettle animals but due to low infection rates the results remain suggestive. Genetic differentiation was not related to survival. Greater negative plant-transfer effect but no negative effect of stolbur in the derived host race suggests preadaptation to the new pathogen/symbiont strain before strong diversifying selection during the specialization process. Physiological maladaptation or failure to accept the ancestral plant will have similar consequences, namely positive assortative

  15. Resolving an identity crisis: Implicit drinking identity and implicit alcohol identity are related but not the same.

    Ramirez, Jason J; Olin, Cecilia C; Lindgren, Kristen P

    2017-09-01

    Two variations of the Implicit Association Test (IAT), the Drinking Identity IAT and the Alcohol Identity IAT, assess implicit associations held in memory between one's identity and alcohol-related constructs. Both have been shown to predict numerous drinking outcomes, but these IATs have never been directly compared to one another. The purpose of this study was to compare these IATs and evaluate their incremental predictive validity. US undergraduate students (N=64, 50% female, mean age=21.98years) completed the Drinking Identity IAT, the Alcohol Identity IAT, an explicit measure of drinking identity, as well as measures of typical alcohol consumption and hazardous drinking. When evaluated in separate regression models that controlled for explicit drinking identity, results indicated that the Drinking Identity IAT and the Alcohol Identity IAT were significant, positive predictors of typical alcohol consumption, and that the Drinking Identity IAT, but not the Alcohol Identity IAT, was a significant predictor of hazardous drinking. When evaluated in the same regression models, the Drinking Identity IAT, but not the Alcohol Identity IAT, was significantly associated with typical and hazardous drinking. These results suggest that the Drinking Identity IAT and Alcohol Identity IAT are related but not redundant. Moreover, given that the Drinking Identity IAT, but not the Alcohol Identity IAT, incrementally predicted variance in drinking outcomes, identification with drinking behavior and social groups, as opposed to identification with alcohol itself, may be an especially strong predictor of drinking outcomes.

    Full Text Available This study examines the use of e-mail as a tool for long term discussion between teachers and grade six students. E-mail messages between grade six students and teachers were collected over the course of one academic year. Methods of conversation analysis within a framework of social practice are used to examine the data. While identity is more readily constructed and more fully developed in contexts which allow for physical embodiment such as face-to-face discussion, this analysis found that identity can be constructed in a context that does not provide for the physical embodiment of identity: Identity was constructed using the social, cultural, and technological tools provided and supported by e-mail to develop social practices germane to the e-mail discussion. This study has implications for further understanding the relation between identity, goals, constraints and affordances, and the collaborative creation of social practices in asynchronous computer mediated communication.

  18. Two analytical models for evaluating performance of Gigabit Ethernet Hosts

    International Nuclear Information System (INIS)

    Salah, K.

    2006-01-01

    Two analytical models are developed to study the impact of interrupt overhead on operating system performance of network hosts when subjected to Gigabit network traffic. Under heavy network traffic, the system performance will be negatively affected due to interrupt overhead caused by incoming traffic. In particular, excessive latency and significant degradation in system throughput can be experienced. Also user application may livelock as the CPU power is mostly consumed by interrupt handling and protocol processing. In this paper we present and compare two analytical models that capture host behavior and evaluate its performance. The first model is based Markov processes and queuing theory, while the second, which is more accurate but more complex is a pure Markov process. For the most part both models give mathematically-equivalent closed-form solutions for a number of important system performance metrics. These metrics include throughput, latency and stability condition, CPU utilization of interrupt handling and protocol processing and CPU availability for user applications. The analysis yields insight into understanding and predicting the impact of system and network choices on the performance of interrupt-driven systems when subjected to light and heavy network loads. More, importantly, our analytical work can also be valuable in improving host performance. The paper gives guidelines and recommendations to address design and implementation issues. Simulation and reported experimental results show that our analytical models are valid and give a good approximation. (author)

    To compare the lung and breast dose associated with three chest protocols: standard, organ-based tube current modulation (OBTCM) and fast-speed scanning; and to estimate the error associated with organ dose when modelling the longitudinal (z-) TCM versus the 3D-TCM in Monte Carlo simulations (MC) for these three protocols. Five adult and three paediatric cadavers with different BMI were scanned. The CTDI vol of the OBTCM and the fast-speed protocols were matched to the patient-specific CTDI vol of the standard protocol. Lung and breast doses were estimated using MC with both z- and 3D-TCM simulated and compared between protocols. The fast-speed scanning protocol delivered the highest doses. A slight reduction for breast dose (up to 5.1%) was observed for two of the three female cadavers with the OBTCM in comparison to the standard. For both adult and paediatric, the implementation of the z-TCM data only for organ dose estimation resulted in 10.0% accuracy for the standard and fast-speed protocols, while relative dose differences were up to 15.3% for the OBTCM protocol. At identical CTDI vol values, the standard protocol delivered the lowest overall doses. Only for the OBTCM protocol is the 3D-TCM needed if an accurate (<10.0%) organ dosimetry is desired. • The z-TCM information is sufficient for accurate dosimetry for standard protocols. • The z-TCM information is sufficient for accurate dosimetry for fast-speed scanning protocols. • For organ-based TCM schemes, the 3D-TCM information is necessary for accurate dosimetry. • At identical CTDI vol , the fast-speed scanning protocol delivered the highest doses. • Lung dose was higher in XCare than standard protocol at identical CTDI vol .

    Full Text Available During the past two decades a steady increase in scholarly contributions in the area of organisation identity have been observed – to the point that the phenomenon is now the subject of a sustainable discourse in several disciplines. Many theoretical and conceptual dilemmas however remain, largely as a result of the low incidence of empirical research in the area. This study reports the results of an exploratory investigation that adapted Schley and Wagenfield’s (1979 concept of identity for use in an organisational setting. Interviews were conducted with 152 top managers representing 10 companies. The results indicate that organisational responses to the question “who am I?�? elicit distinctive organisational self-descriptions and some awareness of identity issues.

    2012-01-01

    The explosion of healthcare costs over the last decade has prompted the ICT industry to respond with solutions for reducing costs while improving healthcare quality. The ISO/IEEE 11073 family of standards recently released is the first step towards interoperability of mobile medical devices used in patient environments. The standards do not, however, tackle security problems, such as identity management, or the secure exchange of medical data. This paper proposes an enhancement of the ISO/IEEE 11073-20601 protocol with an identity management system based on biometry. The paper describes a novel biometric-based authentication process, together with the biometric key generation algorithm. The proposed extension of the ISO/IEEE 11073-20601 is also presented.

    Full Text Available Gossip protocols aim at arriving, by means of point-to-point or group communications, at a situation in which all the agents know each other's secrets. We consider distributed gossip protocols which are expressed by means of epistemic logic. We provide an operational semantics of such protocols and set up an appropriate framework to argue about their correctness. Then we analyze specific protocols for complete graphs and for directed rings.

  6. Hierarchy of modular graph identities

    2016-01-01

    The low energy expansion of Type II superstring amplitudes at genus one is organized in terms of modular graph functions associated with Feynman graphs of a conformal scalar field on the torus. In earlier work, surprising identities between two-loop graphs at all weights, and between higher-loop graphs of weights four and five were constructed. In the present paper, these results are generalized in two complementary directions. First, all identities at weight six and all dihedral identities at weight seven are obtained and proven. Whenever the Laurent polynomial at the cusp is available, the form of these identities confirms the pattern by which the vanishing of the Laurent polynomial governs the full modular identity. Second, the family of modular graph functions is extended to include all graphs with derivative couplings and worldsheet fermions. These extended families of modular graph functions are shown to obey a hierarchy of inhomogeneous Laplace eigenvalue equations. The eigenvalues are calculated analytically for the simplest infinite sub-families and obtained by Maple for successively more complicated sub-families. The spectrum is shown to consist solely of eigenvalues s(s−1) for positive integers s bounded by the weight, with multiplicities which exhibit rich representation-theoretic patterns.

    Full Text Available The purpose of this study was to investigate the factors influencing the identity deaf adolescents. The study involved 67 deaf adolescents (38 boys and 29 girls aged 16 to 19 students of secondary school. Ninety-three hearing children constituted a comparison group. The structure of identity was explored on the basis of identification references given by the subjects who were to reply in writing, 20 times running, to the question: „Who Am I?” the test, adapted from M. H. Kuhn and T. S. McPartland by Martines and Silvestre (1995 given in written and signed mode.Results showed that the hearing status as well as mode of communication influence the description of personal identity. It was found that deaf adoles­cents used more descriptions especially in the fol­lowing categories: Civil Status, Body and Physical Appearance, Tastes and Activities, Friendship and Relationships, Personal and Social Situation, Negative Personal Traits, and Neutral Personality Traits. Although this study could demonstrate im­pact independent variables on identity, the data raise the need for further, preferably longitudinal, research. This complex phenomenon has to be examined more closely.Combined self-descriptive processes lead to the development of an organized, learned and dynamic identity, and subjective description of an individ­ual has strong emotional consequences for the in­dividual in question.

  9. Quantum entanglement of identical particles

    2003-01-01

    We consider entanglement in a system with a fixed number of identical particles. Since any operation should be symmetrized over all the identical particles and there is the precondition that the spatial wave functions overlap, the meaning of identical-particle entanglement is fundamentally different from that of distinguishable particles. The identical-particle counterpart of the Schmidt basis is shown to be the single-particle basis in which the one-particle reduced density matrix is diagonal. But it does not play a special role in the issue of entanglement, which depends on the single-particle basis chosen. The nonfactorization due to (anti)symmetrization is naturally excluded by using the (anti)symmetrized basis or, equivalently, the particle number representation. The natural degrees of freedom in quantifying the identical-particle entanglement in a chosen single-particle basis are occupation numbers of different single-particle basis states. The entanglement between effectively distinguishable spins is shown to be a special case of the occupation-number entanglement

    Full Text Available How could patterns of leisure represent social identity? Whether they are sub-ordinate to the class identity or in the contemporary context of consumption and the post-modern cultural transformations, they could represent some other different social identities based on the patterns of consumption? Considering “leisure time” as a part of “style of life”, the present study attempts to explore social identity. There are two parts in methodology; first the qualitative one, carried through deep interview technique; and the other, surveying through questionnaire. Results distinguish the determining role “social class”, and the combination of “gender” and social class play in modeling distinctions in leisure patterns. In other words, leisure –as the arena for individual choice- is restricted to the social class and gender –as the structural and contextual variables. The strong correlation identity has with the social class and gender denies the post-modern interpretations which emphasis on consumption as the cause of social differentiations.

These operations naturally extend the well-studied Swap Test on two quantum states. We first show the optimality of the Permutation Test for any input size n as well as the optimality of the Circle Test for three input states. In particular, when n=3, we present a semi-classical protocol, incorporated with the Swap Test, which approximates the Circle Test efficiently. Furt...

    2010-01-01

    We consider the problem of deciding if some multiparty entangled pure state can be converted, with a nonzero success probability, into a given bipartite pure state shared between two specified parties through local quantum operations and classical communication. We show that this question is equivalent to the well-known computational problem of deciding if a multivariate polynomial is identically zero. Efficient randomized algorithms developed to study the latter can thus be applied to our question. As a result, a given transformation is possible if and only if it is generically attainable by a simple randomized protocol.

    2016-03-01

    Full Text Available OBJECTIVE: To propose and test the applicability of a dysphonia risk screening protocol with score calculation in individuals with and without dysphonia. METHOD: This descriptive cross-sectional study included 365 individuals (41 children, 142 adult women, 91 adult men and 91 seniors divided into a dysphonic group and a non-dysphonic group. The protocol consisted of 18 questions and a score was calculated using a 10-cm visual analog scale. The measured value on the visual analog scale was added to the overall score, along with other partial scores. Speech samples allowed for analysis/assessment of the overall degree of vocal deviation and initial definition of the respective groups and after six months, the separation of the groups was confirmed using an acoustic analysis. RESULTS: The mean total scores were different between the groups in all samples. Values ranged between 37.0 and 57.85 in the dysphonic group and between 12.95 and 19.28 in the non-dysphonic group, with overall means of 46.09 and 15.55, respectively. High sensitivity and specificity were demonstrated when discriminating between the groups with the following cut-off points: 22.50 (children, 29.25 (adult women, 22.75 (adult men, and 27.10 (seniors. CONCLUSION: The protocol demonstrated high sensitivity and specificity in differentiating groups of individuals with and without dysphonia in different sample groups and is thus an effective instrument for use in voice clinics.

    Full Text Available The purpose of this article is to throw some light on the question of identity in the European Union. The challenge is to understand how identity formation takes place in the contemporary world. The European integration has to be understood both as a process of socio-economic convergence among European states but also as a process of co-operation on different other levels, too. It seems that cultures, traditions and interests are more and more interconnected as societies become increasingly multicultural. This is the reason why people are concerned with the concept of identity and the recognition of their uniqueness in terms of traditions, values and ways of lives.

    Full Text Available In today's globalized world, it is important to find a relationship to our own culture as well as to the other cultures which we encounter due to migration. This goal should be met in multicultural education. As a result of the so-called migration crisis, effectiveness of multicultural education was discussed on social networks and in media. At the same time, national interests and security began to appear in the programmes of political parties. It seems that, due to the fear of refugees, national identity started becoming more important. The situation is reflected in the research presented below. It aimed to determine whether there was a link between the sense of national identity and attitudes to foreigners. The investigation was carried out in 2015 on a sample of 245 respondents. The results showed that the growing sense of national identity deepened the negative attitude to foreigners. It is necessary to work with this fact in multicultural education at schools.

    2011-11-01

    We study the protocol dependence of the mechanical properties of granular media by means of computer simulations. We control a protocol of realizing disk packings in a systematic manner. In 2D, by keeping material properties of the constituents identical, we carry out compaction with various strain rates. The disk packings exhibit the strain rate dependence of the critical packing fraction above which the pressure becomes non-zero. The observed behavior contrasts with the well-studied jamming transitions for frictionless disk packings. We also observe that the elastic moduli of the disk packings depend on the strain rate logarithmically. Our results suggest that there exists a time-dependent state variable to describe macroscopic material properties of disk packings, which depend on its protocol.

    2017-12-01

    Full Text Available Ticks are able to transmit tick-borne infectious agents to vertebrate hosts which cause major constraints to public and livestock health. The costs associated with mortality, relapse, treatments, and decreased production yields are economically significant. Ticks adapted to a hematophagous existence after the vertebrate hemostatic system evolved into a multi-layered defense system against foreign invasion (pathogens and ectoparasites, blood loss, and immune responses. Subsequently, ticks evolved by developing an ability to suppress the vertebrate host immune system with a devastating impact particularly for exotic and crossbred cattle. Host genetics defines the immune responsiveness against ticks and tick-borne pathogens. To gain an insight into the naturally acquired resistant and susceptible cattle breed against ticks, studies have been conducted comparing the incidence of tick infestation on bovine hosts from divergent genetic backgrounds. It is well-documented that purebred and crossbred Bos taurus indicus cattle are more resistant to ticks and tick-borne pathogens compared to purebred European Bos taurus taurus cattle. Genetic studies identifying Quantitative Trait Loci markers using microsatellites and SNPs have been inconsistent with very low percentages relating phenotypic variation with tick infestation. Several skin gene expression and immunological studies have been undertaken using different breeds, different samples (peripheral blood, skin with tick feeding, infestation protocols and geographic environments. Susceptible breeds were commonly found to be associated with the increased expression of toll like receptors, MHC Class II, calcium binding proteins, and complement factors with an increased presence of neutrophils in the skin following tick feeding. Resistant breeds had higher levels of T cells present in the skin prior to tick infestation and thus seem to respond to ticks more efficiently. The skin of resistant breeds also

  15. Men as victims: "victim" identities, gay identities, and masculinities.

    Science.gov (United States)

    Dunn, Peter

    2012-11-01

    The impact and meanings of homophobic violence on gay men's identities are explored with a particular focus on their identities as men and as gay men. Homosexuality can pose a challenge to conventional masculinities, and for some gay men, being victimized on account of sexual orientation reawakens conflicts about their masculinity that they thought they had resolved. Being victimized can reinvoke shame that is rooted in failure or unwillingness to uphold masculine norms. For some gay men, victimization therefore has connotations of nonmasculinity that make being a victim an undesirable status, yet that status must be claimed to obtain a response from criminal justice or victim services. Men who experience homophobic abuse are helped by accepting a victim identity, but only if they can quickly move on from it by reconstructing a masculine gay (nonvictim) identity. This process can be facilitated by agencies such as the police and victim services, provided they help men exercise agency in "fighting back," that is, resisting further victimization and recovering.

    2017-08-01

    Little is known about the adaptive capacity of arbuscular mycorrhizal (AM) fungi to novel hosts. Here we assessed the possibility of two heterospecific AM fungal isolates to adaptively change, in terms of host biomass response, as a function of host plant identity, over the course of a growing season. First, we produced pure inocula of Rhizophagus clarus and Rhizophagus intraradices, each starting from a single spore. Second, we "trained" each isolate individually in a community with two plants, sudangrass (Sorgum bicolour subsp. drummondii) and leek (Aliium ampeloprasum var. porrum), using a dual-compartment system to allow the establishment of a common mycorrhizal network between the two hosts. Third, we conducted a greenhouse experiment to reciprocally test each "trained" clone, obtained from each compartment, either with the same (home), or the other host (away) under two contrasting phosphorus levels. Overall, results did not support adaptive responses of the AM fungi to their hosts (i.e., greater host biomass under "home" relative to "away" conditions), but the opposite (i.e., greater host biomass under "away" relative to "home" conditions) was more frequently observed. These changes in AM fungal symbiotic functioning open the possibility for relatively rapid genetic change of arbuscular mycorrhizal fungi in response to new hosts, which represents one step forward from in vitro experiments.

Sandia Laboratories makes a continuing effort to stay abreast of identity verifier developments and to assess the capabilities and improvements of each device. Operating environment and procedures more typical of field use can often reveal performance results substantially different from laboratory tests. An evaluation of several recently available verifiers is herein reported

    Assumed determinants of ego identity were investigated in this study using sophomore, junior, and senior high school males and females. Subjects were administered the Marcia Ego Identity Status Scale and measures of sex-role identification, personality development, psychological functioning, self-concept, and parental socialization practices. Data analyses, using a median split on identity score, showed that high-identity adolescents obtained more positive scores on sex-role identification, personality development, psychological adjustment, and self-concept than low-identity adolescents. Socialization practices also differed for the two groups. The sex differences which emerged were congruent with the identity literature. Overall, the data supported Erikson's theory of ego identity development.

    The galactic environment of gamma-ray bursts can provide good evidence about the nature of the progenitor system, with two old arguments implying that the burst host galaxies are significantly subluminous. New data and new analysis have now reversed this picture: (1) Even though the first two known host galaxies are indeed greatly subluminous, the next eight hosts have absolute magnitudes typical for a population of field galaxies. A detailed analysis of the 16 known hosts (10 with redshifts) shows them to be consistent with a Schechter luminosity function with R*=-21.8+/-1.0, as expected for normal galaxies. (2) Bright bursts from the Interplanetary Network are typically 18 times brighter than the faint bursts with redshifts; however, the bright bursts do not have galaxies inside their error boxes to limits deeper than expected based on the luminosities for the two samples being identical. A new solution to this dilemma is that a broad burst luminosity function along with a burst number density varying as the star formation rate will require the average luminosity of the bright sample (>6x1058 photons s-1 or>1.7x1052 ergs s-1) to be much greater than the average luminosity of the faint sample ( approximately 1058 photons s-1 or approximately 3x1051 ergs s-1). This places the bright bursts at distances for which host galaxies with a normal luminosity will not violate the observed limits. In conclusion, all current evidence points to gamma-ray burst host galaxies being normal in luminosity.

  3. Porphyromonas gingivalis as a Model Organism for Assessing Interaction of Anaerobic Bacteria with Host Cells.

    Anaerobic bacteria far outnumber aerobes in many human niches such as the gut, mouth, and vagina. Furthermore, anaerobic infections are common and frequently of indigenous origin. The ability of some anaerobic pathogens to invade human cells gives them adaptive measures to escape innate immunity as well as to modulate host cell behavior. However, ensuring that the anaerobic bacteria are live during experimental investigation of the events may pose challenges. Porphyromonas gingivalis, a Gram-negative anaerobe, is capable of invading a variety of eukaryotic non-phagocytic cells. This article outlines how to successfully culture and assess the ability of P. gingivalis to invade human umbilical vein endothelial cells (HUVECs). Two protocols were developed: one to measure bacteria that can successfully invade and survive within the host, and the other to visualize bacteria interacting with host cells. These techniques necessitate the use of an anaerobic chamber to supply P. gingivalis with an anaerobic environment for optimal growth. The first protocol is based on the antibiotic protection assay, which is largely used to study the invasion of host cells by bacteria. However, the antibiotic protection assay is limited; only intracellular bacteria that are culturable following antibiotic treatment and host cell lysis are measured. To assess all bacteria interacting with host cells, both live and dead, we developed a protocol that uses fluorescent microscopy to examine host-pathogen interaction. Bacteria are fluorescently labeled with 2',7'-Bis-(2-carboxyethyl)-5-(and-6)-carboxyfluorescein acetoxymethyl ester (BCECF-AM) and used to infect eukaryotic cells under anaerobic conditions. Following fixing with paraformaldehyde and permeabilization with 0.2% Triton X-100, host cells are labeled with TRITC phalloidin and DAPI to label the cell cytoskeleton and nucleus, respectively. Multiple images taken at different focal points (Z-stack) are obtained for temporal

  4. Combining Phylogenetic and Occurrence Information for Risk Assessment of Pest and Pathogen Interactions with Host Plants

    Full Text Available Phytosanitary agencies conduct plant biosecurity activities, including early detection of potential introduction pathways, to improve control and eradication of pest and pathogen incursions. For such actions, analytical tools based on solid scientific knowledge regarding plant-pest or pathogen relationships for pest risk assessment are needed. Recent evidence indicating that closely related species share a higher chance of becoming infected or attacked by pests has allowed the identification of taxa with different degrees of vulnerability. Here, we use information readily available online about pest-host interactions and their geographic distributions, in combination with host phylogenetic reconstructions, to estimate a pest-host interaction (in some cases infection index in geographic space as a more comprehensive, spatially explicit tool for risk assessment. We demonstrate this protocol using phylogenetic relationships for 20 beetle species and 235 host plant genera: first, we estimate the probability of a host sharing pests, and second, we project the index in geographic space. Overall, the predictions allow identification of the pest-host interaction type (e.g., generalist or specialist, which is largely determined by both host range and phylogenetic constraints. Furthermore, the results can be valuable in terms of identifying hotspots where pests and vulnerable hosts interact. This knowledge is useful for anticipating biological invasions or spreading of disease. We suggest that our understanding of biotic interactions will improve after combining information from multiple dimensions of biodiversity at multiple scales (e.g., phylogenetic signal and host-vector-pathogen geographic distribution.

  6. Herpesvirus papio 2 encodes a virion host shutoff function.

    2002-12-05

    Infection of baboons with herpesvirus papio 2 (HVP-2) produces a disease that is similar to human infection with herpes simplex viruses (HSV). Molecular characterization of HVP-2 has demonstrated that the virion contains a factor which rapidly shuts off host cell protein synthesis after infection. Reduction of host cell protein synthesis occurs in parallel with the degradation of mRNA species. A homolog of the HSV virion host shutoff (vhs) gene was identified by Southern and DNA sequence analysis. The sequence of the HVP-2 vhs gene homolog had greater than 70% identity with the vhs genes of HSV 1 and 2. Disruption of the HVP-2 vhs open reading frame diminished the ability of the virus to shut off protein synthesis and degrade cellular mRNA, indicating that this gene was responsible for the vhs activity. The HVP-2 model system provides the opportunity to study the biological role of vhs in the context of a natural primate host. Further development of this system will provide a platform for proof-of-concept studies that will test the efficacy of vaccines that utilize vhs-deficient viruses.

    For the whole set of dilogarithm identities found recently using the thermodynamic Bethe-Ansatz for the ADET series of purely elastic scattering theories we give partition identities which involve characters of those conformal field theories which correspond to the UV-limits of the scattering theories. These partition identities in turn allow to derive the dilogarithm identities using modular invariance and a saddle point approximation. We conjecture on possible generalizations of this correspondance, namely, a lift from dilogarithm to partition identities. (orig.)

  9. The Inflammasome in Host Defense

    2009-12-01

    Full Text Available Nod-like receptors have emerged as an important family of sensors in host defense. These receptors are expressed in macrophages, dendritic cells and monocytes and play an important role in microbial immunity. Some Nod-like receptors form the inflammasome, a protein complex that activates caspase-1 in response to several stimuli. Caspase-1 activation leads to processing and secretion of pro-inflammatory cytokines such as interleukin (IL-1β and IL-18. Here, we discuss recent advances in the inflammasome field with an emphasis on host defense. We also compare differential requirements for inflammasome activation in dendritic cells, macrophages and monocytes.

    Arfuch, Leonor

    2013-01-01

    This paper aims to tackle the subtle relation between autobiographical narratives and identity construction, from a non essentialist conception of identity. In a perspective that articulates philosophy of language, psychoanalysis, semiotics and literary critique, we posit the concept of biographical space as an analytical instrument to make a critical update of the reconfiguration of identities and subjectivities in contemporary culture, marked by the predominance of the biographical, the private and a kind of "public intimacy". This look is more symptomatic than descriptive: it intends to account for the rise of auto/biographical narratives and life-stories, from canonic genres to their multiple derivations in the media, social networks and the most diverse artistic practices, a phenomenon that seems to reaffirm the notion of narrative identities by Ricoeur. Our analysis here, from an ethic, aesthetic and political point of view, will focus on two visual arts experiences that have recently taken place for the first time in Buenos Aires: Christian Boltanski's and Tracey Emin's, solo exhibitions, each of them with a different biographical approach.

  20. Identity, causality, and pronoun ambiguity.

    Science.gov (United States)

    Sagi, Eyal; Rips, Lance J

    2014-10-01

    This article looks at the way people determine the antecedent of a pronoun in sentence pairs, such as: Albert invited Ron to dinner. He spent hours cleaning the house. The experiment reported here is motivated by the idea that such judgments depend on reasoning about identity (e.g., the identity of the he who cleaned the house). Because the identity of an individual over time depends on the causal-historical path connecting the stages of the individual, the correct antecedent will also depend on causal connections. The experiment varied how likely it is that the event of the first sentence (e.g., the invitation) would cause the event of the second (the house cleaning) for each of the two individuals (the likelihood that if Albert invited Ron to dinner, this would cause Albert to clean the house, versus cause Ron to clean the house). Decisions about the antecedent followed causal likelihood. A mathematical model of causal identity accounted for most of the key aspects of the data from the individual sentence pairs.

    2000-06-01

    Full Text Available The research work done by the author investigates a phenomenological field—the subjective experience of chronic illness and disability—by means of a specific research instrument, the autobiographical narrative interview. It focuses on the concept of narrative identity and its empirical substrate in the scientifically generated texts. Narrative identity is regarded as a situated, pragmatic, autoepistemic and interactive activity drawing on culturally transmitted narrative conventions which is performed within the research context. We have been working with a systematic analytic approach which covers interactive and contextual aspects of the interview situation as well as rhetoric and positioning strategies in the act of telling. Other research questions concern the concept of "narrative coping" and the comparison of partner's narratives on problems of illness and disability, especially on scrutinizing aspects of identity and alterity (self and other in the texts. This work can be understood as combining aspects of the research domains of narratology, identity and coping on the background of a qualitative methodology. URN: urn:nbn:de:0114-fqs0002189

    Human sterile alpha motif domain-containing 9 (SAMD9) protein is a host restriction factor for poxviruses, but it can be overcome by some poxvirus host-range proteins that share homology with vaccinia virus C7 protein. To understand the mechanism of action for this important family of host-range factors, we determined the crystal structures of C7 and myxoma virus M64, a C7 family member that is unable to antagonize SAMD9. Despite their different functions and only 23% sequence identity, the two proteins have very similar overall structures, displaying a previously unidentified fold comprised of a compact 12-stranded antiparallel β-sandwich wrapped in two short α helices. Extensive structure-guided mutagenesis of C7 identified three loops clustered on one edge of the β sandwich as critical for viral replication and binding with SAMD9. The loops are characterized with functionally important negatively charged, positively charged, and hydrophobic residues, respectively, together forming a unique "three-fingered molecular claw." The key residues of the claw are not conserved in two C7 family members that do not antagonize SAMD9 but are conserved in distantly related C7 family members from four poxvirus genera that infect diverse mammalian species. Indeed, we found that all in the latter group of proteins bind SAMD9. Taken together, our data indicate that diverse mammalian poxviruses use a conserved molecular claw in a C7-like protein to target SAMD9 and overcome host restriction.

    The increasing prevalence of obesity and overweight in childhood in developing countries is a public health concern to many governments. Schools play a significant role in the obesity epidemic as well as provide favourable environments for change in behaviours in childhood which can be carried on into adulthood. There is dearth of information on intervention studies in poor-resource settings. This review will summarise the available evidence on school-based interventions that focused on promoting healthy eating and physical activity among learners aged 6-15 years in Africa and to identify factors that lead to successful interventions or potential barriers to success of these programmes within the African context. This protocol is developed following the guidelines of PRIMSA-P 2015. Relevant search terms and keywords generated from the subject headings and the African search filter will be used to conduct a comprehensive search of MEDLINE (PubMed), MEDLINE (EbscoHost), CINAHL (EbscoHost), Register Academic Search Complete (EbscoHost) and ISI Web of Science (Science Citation Index) for published literature on school-based interventions to prevent and control obesity in learners in Africa. Grey literature will be also be obtained. The searches will cover 1 January 2000 to 30 June 2016. No language limitations will be applied. Full-text articles of eligible studies will be screened. Risk of bias and quality of reporting will be assessed. Data will be extracted, synthesised and presented by country and major regional groupings. Meta-analysis will be conducted for identical variables across studies, where data allow. This protocol is developed following the guidelines of PRISMA-P 2015. No primary data will be collected hence ethics is not a requirement. The findings will be submitted for publication in peer-reviewed journals, in conferences and in policy documents for decision-making, where needed. Published by the BMJ Publishing Group Limited.

    Full text: HIDA biliary studies examine the gallbladder (GB) to give a percentage ejection fraction (EF). Porcine CCK was an accepted agent for stimulating the GB prior to being withdrawn in the UK from 1998. Sincalide (a synthetic CCK) was the suggested replacement. We have tried many administration regimes in an attempt to get results comparable with our established CCK protocols. Dose concentration and length of infusion times have been studied. Initially a dose of 10 ngm/kg/min given over 2 minutes (manufacturer's recommended dose) was used. This gave falsely low ejection fractions. The dose was reduced to 3 ngm/kg/min over 3 minutes as it was felt the higher dose may be causing constriction of the sphincter of Oddi. This gave a slight improvement with 22 % of patients having normal EF (>35 %). The length of infusion was extended to 15 minutes and the dose concentration reduced again to 0.6 ngm/kg/min. 62 % of patients had a normal EF. However, on many of the curves the gallbladder was still contracting on completion of the 15 minute infusion and began to refill immediately after stopping Sincalide. A further change of protocol was indicated. The infusion time was extended to 30 minutes and the dose concentration per minute kept the same. Imaging began at 30 minutes post HIDA injection and continued for a total of 50 minutes. Sincalide infusion began at 35 minutes if a GB was visualized. This protocol has been performed on 17 patients. 53 % of these had a normal result (comparable with a normal rate of 40 % previously established with CCK) with a mean EF of 60 %. The mean EF of patients with abnormal studies was 15 %. Curves showed a plateau by 30 minutes in 94 % of patients indicating that gallbladder contraction was complete. No normal range is available so results were compared with ultrasound (US). All patients who had an abnormal US scan also had abnormal HIDA results. Three patients had a normal US scan and abnormal HIDA study. These are currently

    Bacillus subtilis (B. subtilis) is a potential and attractive host for the production of recombinant proteins. Different expression systems for B. subtilis have been developed recently, and various target proteins have been recombinantly synthesized and purified using this host. In this chapter, we introduce a generic protocol to express a recombinant protein in B. subtilis. It includes protocols for (1) using our typical expression vector (plasmid pHT254) to introduce a target gene, (2) transformation of the target vector into B. subtilis, and (3) evaluation of the actual expression of a recombinant protein.

  3. Host Event Based Network Monitoring

    2013-01-01

    The purpose of INL’s research on this project is to demonstrate the feasibility of a host event based network monitoring tool and the effects on host performance. Current host based network monitoring tools work on polling which can miss activity if it occurs between polls. Instead of polling, a tool could be developed that makes use of event APIs in the operating system to receive asynchronous notifications of network activity. Analysis and logging of these events will allow the tool to construct the complete real-time and historical network configuration of the host while the tool is running. This research focused on three major operating systems commonly used by SCADA systems: Linux, WindowsXP, and Windows7. Windows 7 offers two paths that have minimal impact on the system and should be seriously considered. First is the new Windows Event Logging API, and, second, Windows 7 offers the ALE API within WFP. Any future work should focus on these methods.

  4. Intergroup Leadership Across Distinct Subgroups and Identities.

    Rast, David E; Hogg, Michael A; van Knippenberg, Daan

    2018-03-01

    Resolving intergroup conflict is a significant and often arduous leadership challenge, yet existing theory and research rarely, if ever, discuss or examine this situation. Leaders confront a significant challenge when they provide leadership across deep divisions between distinct subgroups defined by self-contained identities-The challenge is to avoid provoking subgroup identity distinctiveness threat. Drawing on intergroup leadership theory, three studies were conducted to test the core hypothesis that, where identity threat exists, leaders promoting an intergroup relational identity will be better evaluated and are more effective than leaders promoting a collective identity; in the absence of threat, leaders promoting a collective identity will prevail. Studies 1 and 2 ( N = 170; N = 120) supported this general proposition. Study 3 ( N = 136) extended these findings, showing that leaders promoting an intergroup relational identity, but not a collective identity, improved intergroup attitudes when participants experienced an identity distinctiveness threat.

  5. Security and SCADA protocols

    International Nuclear Information System (INIS)

    Igure, V. M.; Williams, R. D.

    2006-01-01

    Supervisory control and data acquisition (SCADA) networks have replaced discrete wiring for many industrial processes, and the efficiency of the network alternative suggests a trend toward more SCADA networks in the future. This paper broadly considers SCADA to include distributed control systems (DCS) and digital control systems. These networks offer many advantages, but they also introduce potential vulnerabilities that can be exploited by adversaries. Inter-connectivity exposes SCADA networks to many of the same threats that face the public internet and many of the established defenses therefore show promise if adapted to the SCADA differences. This paper provides an overview of security issues in SCADA networks and ongoing efforts to improve the security of these networks. Initially, a few samples from the range of threats to SCADA network security are offered. Next, attention is focused on security assessment of SCADA communication protocols. Three challenges must be addressed to strengthen SCADA networks. Access control mechanisms need to be introduced or strengthened, improvements are needed inside of the network to enhance security and network monitoring, and SCADA security management improvements and policies are needed. This paper discusses each of these challenges. This paper uses the Profibus protocol as an example to illustrate some of the vulnerabilities that arise within SCADA networks. The example Profibus security assessment establishes a network model and an attacker model before proceeding to a list of example attacks. (authors)

    Full Text Available How to verify the integrity of outsourced data is an important problem in cloud storage. Most of previous work focuses on three aspects, which are providing data dynamics, public verifiability, and privacy against verifiers with the help of a third party auditor. In this paper, we propose an identity-based data storage and integrity verification protocol on untrusted cloud. And the proposed protocol can guarantee fair results without any third verifying auditor. The theoretical analysis and simulation results show that our protocols are secure and efficient.

    Emission rates and other optical properties of multi-particle systems in collective and entangled states differ from those in product ones. We show the existence of similar effects in the absorption probabilities for (anti)symmetrized states of two identical atoms. The effects strongly depend on the overlapping between the atoms and differ for bosons and fermions. We propose a viable experimental verification of these ideas. -- Highlights: •The absorption rates of a pair of identical atoms in product and (anti)symmetrized states are different. •The modifications of the optical properties are essentially determined by the overlapping between the atoms. •The absorption properties differ, in some cases, for bosons and fermions

  10. Variational identities and Hamiltonian structures

    International Nuclear Information System (INIS)

    Ma Wenxiu

    2010-01-01

    This report is concerned with Hamiltonian structures of classical and super soliton hierarchies. In the classical case, basic tools are variational identities associated with continuous and discrete matrix spectral problems, targeted to soliton equations derived from zero curvature equations over general Lie algebras, both semisimple and non-semisimple. In the super case, a supertrace identity is presented for constructing Hamiltonian structures of super soliton equations associated with Lie superalgebras. We illustrate the general theories by the KdV hierarchy, the Volterra lattice hierarchy, the super AKNS hierarchy, and two hierarchies of dark KdV equations and dark Volterra lattices. The resulting Hamiltonian structures show the commutativity of each hierarchy discussed and thus the existence of infinitely many commuting symmetries and conservation laws.

    Full Text Available The article examines the potentials of the concept of othering to describe identity formation among ethnic minorities. First, it outlines the history of the concept, its contemporary use, as well as some criticisms. Then it is argued that young ethnic minority men in Denmark are subject to intersectional othering, which contains elements of exoticist fascination of the other. On the basis of ethnographic material, it is analysed how young marginalized ethnic minority men react to othering. Two types of reactions are illustrated: 1 capitalization on being positioned as the other, and 2 refusing to occupy the position of the other by disidentification and claims to normality. Finally, it is argued that the concept of othering is well suited for understanding the power structures as well as the historic symbolic meanings conditioning such identity formation, but problematic in terms of agency.

    Full Text Available Pleasure is an important motivation for fans to adopt texts. Fannish tattoos function to demonstrate affective investments in a text; they are also a performance of fandom and an example of sacred fan identity. Like engaging in cosplay or wearing clothing that features logos, fannish tattoos mark people as fans of a text. Furthermore, the more obscure the logo or fannish reference, the more performative the tattoo. Fannish tattoos help to construct a sacred fan identity. The sacred experience (as theorized by Émile Durkheim and his concept of the totem is imbued with meaning through choices that set it aside from the mundane. Within the context of fannish tattoos, fan affect gains similar significance.

    Full Text Available Nowadays, when talking about the vaccei, discussions focus on the debate of geographic and cultural boundaries and on the definition of their identity, but bearing in mind that the life of this people was sold for thousands of years by the Roman assimilation. A further reflection makes us wonder if this identity has survived to some extension up to the present: concepts such as the controversial “vaccean collectivism” were used to support various ideological discourses, furthermore it shouldn’t be missed the popular uptake of this ancient people today through Rugby’s team (vacceos cavaliers, partnerships, trademarks and wines with the name of vaccei, among many others. The aim of this paper is to study how the various factors that determine or define that culture have been used over recent history.

    2012-11-01

    Full Text Available Augmentative releases of parasitoids may be a useful tool for the area-wide management of tephritid pests. The latter are parasitized by many wasp species, though only a few of them are relevant for augmentative biocontrol purposes. To date, nearly all the actual or potential biocontrol agents for such programs are egg or larval Opiinae parasitoids (Hymenoptera: Braconidae. Here, we review the literature published on their habitat and host location behavior, as well as the factors that modulate this behavior, which is assumed to be sequential; parasitoids forage first for the host habitat and then for the host itself. Parasitoids rely on chemical, visual, and mechanical stimuli, often strongly related to their ecology. Behavioral modulation factors include biotic and abiotic factors including learning, climatic conditions and physiological state of the insect. Finally, conclusions and perspectives for future research are briefly highlighted. A detailed knowledge of this behavior may be very useful for selecting the release sites for both inundative/augmentative releases of mass-reared parasitoids and inoculative releases for classical biocontrol.

    2018-01-01

    Dissociative identity disorder is characterised by the presence in one individual of two or more alternative personality states (alters). For such individuals, the memory representation of a particular event can have full episodic, autonoetic status for one alter, while having the status of knowledge or even being inaccessible to a second alter. This phenomenon appears to create difficulties for a purely representational theory and is presented to Mahr & Csibra (M&C) for their consideration.

  6. Modelling within-host spatiotemporal dynamics of invasive bacterial disease.

    Directory of Open Access Journals (Sweden)

    Andrew J Grant

    2008-04-01

    Full Text Available Mechanistic determinants of bacterial growth, death, and spread within mammalian hosts cannot be fully resolved studying a single bacterial population. They are also currently poorly understood. Here, we report on the application of sophisticated experimental approaches to map spatiotemporal population dynamics of bacteria during an infection. We analyzed heterogeneous traits of simultaneous infections with tagged Salmonella enterica populations (wild-type isogenic tagged strains [WITS] in wild-type and gene-targeted mice. WITS are phenotypically identical but can be distinguished and enumerated by quantitative PCR, making it possible, using probabilistic models, to estimate bacterial death rate based on the disappearance of strains through time. This multidisciplinary approach allowed us to establish the timing, relative occurrence, and immune control of key infection parameters in a true host-pathogen combination. Our analyses support a model in which shortly after infection, concomitant death and rapid bacterial replication lead to the establishment of independent bacterial subpopulations in different organs, a process controlled by host antimicrobial mechanisms. Later, decreased microbial mortality leads to an exponential increase in the number of bacteria that spread locally, with subsequent mixing of bacteria between organs via bacteraemia and further stochastic selection. This approach provides us with an unprecedented outlook on the pathogenesis of S. enterica infections, illustrating the complex spatial and stochastic effects that drive an infectious disease. The application of the novel method that we present in appropriate and diverse host-pathogen combinations, together with modelling of the data that result, will facilitate a comprehensive view of the spatial and stochastic nature of within-host dynamics.

  7. Human Rights and the Excess of Identity

    Science.gov (United States)

    Al Tamimi, Yussef

    2017-01-01

    Identity is a central theme in contemporary politics, but legal academia lacks a rigorous analysis of this concept. The aim of this article is twofold: (i) firstly, it aims to reveal presumptions on identity in human rights law by mapping how the European Court of Human Rights approaches identity and (ii) secondly, it seeks to analyse these presumptions using theoretical insights on identity. By merging legal and theoretical analysis, this article contributes a reading of the Court’s case law which suggests that the tension between the political and apolitical is visible as a common thread in the Court’s use of identity. In case law concerning paternity, the Court appears to hold a specific view of what is presented as an unquestionable part of identity. This ostensibly pre-political notion of identity becomes untenable in cases where the nature of an identity feature, such as the headscarf, is contended or a minority has adopted a national identity that conflicts with the majoritarian national identity. The Court’s approach to identity in such cases reflects a paradox that is inherent to identity; identity is personal while simultaneously constituted and shaped by overarching power mechanisms.

    Mischenko, Jane

    2005-01-01

    The primary purpose of this paper is to critically explore managers' experience of work identity in the National Health Service (NHS). This paper is unconventional in that it uses an auto-ethnographic approach and poetry as the empirical data from which the conceptual framework evolves. The concepts of identity, power and self are analysed in relation to the narrative utilising a post-structuralist, critical management lens, particularly drawing from Foucault. The paper reflects and critiques the challenges of undertaking auto-ethnography, not least the publication and exposure of a "vulnerable aspect" of the author but also identifies this as a powerful method to explore how one uses narrative to create meaning and constitute oneself, the challenges of such textual representation and the various ways one adapts, resists and survives the challenge of the "multiphrenic" world. The contribution this paper makes is an "outing" of the dynamics of being a manager in the NHS and an opening of a debate on current management discourse and practice. The further value of this paper is the experimentation of critically evaluating an auto-ethnographic approach to researching management identity work.

  13. Identity and power in Ukraine

    Directory of Open Access Journals (Sweden)

    Karina V. Korostelina

    2013-01-01

    Full Text Available This paper analyzes the coercive and legitimate forms of power in Ukraine. It describes the crisis of legitimacy in Ukraine as a contradiction between a blatantly cruel system of capitalism dominated by a few oligarchs, and the lingering remnants of a Soviet mentality. Two strategies are used by the Government to stoke the crisis. First, increased identification with ethnic or regional groups are instrumentally used by the Government to take attention from economic and class issues. Second, the incorporation of a Soviet meaning of power into the new national identity and presentation of it as core norms, believes, and values of the people of Ukraine competes with alternative Ukrainian identity concepts. The paper analyzes five main features of the Soviet meanings of power – political, social, and economic paternalism, perception of power as source of profit and violence, and the dual reality of power with the gap between official narratives of power and a real life. The process of incorporation of the Soviet concept of power into national identity is facilitated by the process of national identity formation that helped to preserve the Soviet perception of power, because of the absence of a new ideology, a lack of critical assessment of the Soviet past, an absence of the vision of outcome, an embryonic culture of democracy, and contributions of all the presidents to the preservation of the Soviet meaning of power. People justify the system as legitimate and fair for many reasons: out of historic habit and deemed moral obligations, self-interests and/or a fear of sanctions, identification with the ruler, zones of indifference, an absence of will and self-confidence, desire to support a strong leader based on ambiguity intolerance, hierarchy – enhancing ideologies, and a general tolerance of injustice. The obedience of subjects is connected with the strength of will of the subjects and the social structures of the society. In Ukraine, the

    Full Text Available The Jyllands-Posten Muhammad cartoons controversy began after twelve editorial cartoons, most of which depicted the Islamic prophet Muhammad, were published in the Danish newspaper Jyllands-Posten on September 30, 2005. The newspaper explained that this publication was a contribution to debate regarding criticism of Islam and self-censorship. In response, Danish Muslim organizations held public protests and spread knowledge of Jyllands-Postens publication. As the controversy grew, some or all of the cartoons were reprinted in newspapers in more than fifty other countries, which led to violent protests, particularly in the Muslim world. Critics of the cartoons describe them as islamophobic and argue that they are blasphemous, intended to humiliate a marginalized Danish minority, and a manifestation of ignorance about the history of western imperialism, from colonialism to the current conflicts in the Middle East. Supporters of the cartoons claim they illustrate an important issue in an age of Islamic extremist terrorism and that their publication is a legitimate exercise of the right of free speech. They also note that similar cartoons about other religions are frequently printed, arguing that the followers of Islam were not targeted in a discriminatory way. The dispute has again pointed out to the relevance of religion and religious differences in the contemporary world. Again, several questions presented themselves as significant: citizen freedom, values and the rights to exercise them, secularism, tolerance, multiculturalism majority-minority relationships and so on. The resolution to these issues appears as of the outmost importance, considering the existing tendencies of united Europe to even more firmly establish cultural, economic, and political associations, in order to launch a one, joined European identity with vanishing national, ethnic and religious differences. Therefore, the question becomes: what could serve as a foundation for

    Physician has to know the patient in the disease and not only the disease in the patient, from the dual perspective of the body as object and the body as subject. This also affects the patient who has to cope with the reality of having a body that bursts into the subject's consciousness as a vital threat, as source of discomfort and inability and being a body (Marcel). The human body in its dual aspect has been and is a great unknown, if not a great outrage in spite of the fact that we are our body and our body is each of us. We sometimes do not feel as we are and thus a confrontation arises, sometimes more normal, others more morbid. This forces the physician to face complex ethics considerations and the scientist to accept a personal identity disorder. Dualism considers that there are two substances in us, one that distinguishes us from other beings and from the rest of the individuals of the human species, the soul, the psychic life, mind or consciousness, and another more insubstancial one, the body. The aim of the first substance is to dominate the body, to survive it after death when it is, already a corpse is meant to become putrefied, is buried, incinerated or thrown to the depth of the sea. This dualism aims to explain the origin of the evil and the attitude to defeat it and it does so efficiently. This anthropology has very ancient roots (the Upvanishads, in the orphic texts, in Plato), it is the core of Gnostic thought and the foundation of the modern science since Descartes. Some monist perspectives are a masked dualism or a mereologic fallacy, according to which, the brain is conscious, when that what is conscious is the subject, although the subject, with the brain could not be conscious. Therefore, a new perspective is proposed, chiasmatic or janicular monism, that considers the adaptive value of focusing on the reality from two perspectives, as physical universe and the world of interpersonal relationships.

    The European Data Relay System (EDRS) will provide optical and microwave data relay services between Low Earth Orbit (LEO) satellites at altitudes up to 2000 km and the ground through geostationary (GEO) satellite nodes. Currently, two such nodes have been procured as part of a Public Private Partnership (PPP) between Astrium (now Airbus Defence and Space) and ESA. The first node (EDRS-A) is a hosted payload embarked upon the Eutelsat 9B satellite and scheduled for launch in early 2015.

  20. Host thin films incorporating nanoparticles

    The focus of this research project was the investigation of the functional properties of thin films that incorporate a secondary nanoparticulate phase. In particular to assess if the secondary nanoparticulate material enhanced a functional property of the coating on glass. In order to achieve this, new thin film deposition methods were developed, namely use of nanopowder precursors, an aerosol assisted transport technique and an aerosol into atmospheric pressure chemical vapour deposition system. Aerosol assisted chemical vapour deposition (AACVD) was used to deposit 8 series of thin films on glass. Five different nanoparticles silver, gold, ceria, tungsten oxide and zinc oxide were tested and shown to successfully deposit thin films incorporating nanoparticles within a host matrix. Silver nanoparticles were synthesised and doped within a titania film by AACVD. This improved solar control properties. A unique aerosol assisted chemical vapour deposition (AACVD) into atmospheric pressure chemical vapour deposition (APCVD) system was used to deposit films of Au nanoparticles and thin films of gold nanoparticles incorporated within a host titania matrix. Incorporation of high refractive index contrast metal oxide particles within a host film altered the film colour. The key goal was to test the potential of nanopowder forms and transfer the suspended nanopowder via an aerosol to a substrate in order to deposit a thin film. Discrete tungsten oxide nanoparticles or ceria nanoparticles within a titanium dioxide thin film enhanced the self-cleaning and photo-induced super-hydrophilicity. The nanopowder precursor study was extended by deposition of zinc oxide thin films incorporating Au nanoparticles and also ZnO films deposited from a ZnO nanopowder precursor. Incorporation of Au nanoparticles within a VO: host matrix improved the thermochromic response, optical and colour properties. Composite VC/TiC and Au nanoparticle/V02/Ti02 thin films displayed three useful

In response, I argue that identity politics only interfere with democratic participation according to an erroneous interpretation of the relationship between identity and reasoning. I argue that recognizing the importance of identity to the intelligibility of reasons offered in the context of civic deliberation is the first step towards the kind of dialogue that democratic participation requires.

  4. AIB-OR: improving onion routing circuit construction using anonymous identity-based cryptosystems.

    Wang, Changji; Shi, Dongyuan; Xu, Xilei

    2015-01-01

    The rapid growth of Internet applications has made communication anonymity an increasingly important or even indispensable security requirement. Onion routing has been employed as an infrastructure for anonymous communication over a public network, which provides anonymous connections that are strongly resistant to both eavesdropping and traffic analysis. However, existing onion routing protocols usually exhibit poor performance due to repeated encryption operations. In this paper, we first present an improved anonymous multi-receiver identity-based encryption (AMRIBE) scheme, and an improved identity-based one-way anonymous key agreement (IBOWAKE) protocol. We then propose an efficient onion routing protocol named AIB-OR that provides provable security and strong anonymity. Our main approach is to use our improved AMRIBE scheme and improved IBOWAKE protocol in onion routing circuit construction. Compared with other onion routing protocols, AIB-OR provides high efficiency, scalability, strong anonymity and fault tolerance. Performance measurements from a prototype implementation show that our proposed AIB-OR can achieve high bandwidths and low latencies when deployed over the Internet.

    Biofilms form in a variety of host sites following infection with many bacterial species. However, the study of biofilms in a host is hindered due to the lack of protocols for the proper experimental investigation of biofilms in vivo. Histophilus somni is an agent of respiratory and systemic...... diseases in bovines, and readily forms biofilms in vitro. In the present study the capability of H. somni to form biofilms in cardiopulmonary tissue following experimental respiratory infection in the bovine host was examined by light microscopy, transmission electron microscopy, immunoelectron microscopy...... haemagglutinin (FHA), predicted to be involved in attachment. Thus, this investigation demonstrated that H. somni is capable of forming a biofilm in its natural host, that such a biofilm may be capable of harboring other bovine respiratory disease pathogens, and that the genes responsible for biofilm formation...

  6. Blocking Optimality in Distributed Real-Time Locking Protocols

    2014-09-01

    Full Text Available Lower and upper bounds on the maximum priority inversion blocking (pi-blocking that is generally unavoidable in distributed multiprocessor real-time locking protocols (where resources may be accessed only from specific synchronization processors are established. Prior work on suspension-based shared-memory multiprocessor locking protocols (which require resources to be accessible from all processors has established asymptotically tight bounds of Ω(m and Ω(n maximum pi-blocking under suspension-oblivious and suspension-aware analysis, respectively, where m denotes the total number of processors and n denotes the number of tasks. In this paper, it is shown that, in the case of distributed semaphore protocols, there exist two different task allocation scenarios that give rise to distinct lower bounds. In the case of co-hosted task allocation, where application tasks may also be assigned to synchronization processors (i.e., processors hosting critical sections, Ω(Φ · n maximum pi-blocking is unavoidable for some tasks under any locking protocol under both suspension-aware and suspension-oblivious schedulability analysis, where Φ denotes the ratio of the maximum response time to the shortest period. In contrast, in the case of disjoint task allocation (i.e., if application tasks may not be assigned to synchronization processors, only Ω(m and Ω(n maximum pi-blocking is fundamentally unavoidable under suspension-oblivious and suspension-aware analysis, respectively, as in the shared-memory case. These bounds are shown to be asymptotically tight with the construction of two new distributed real-time locking protocols that ensure O(m and O(n maximum pi-blocking under suspension-oblivious and suspension-aware analysis, respectively.

  7. A Self-Stabilizing Distributed Clock Synchronization Protocol for Arbitrary Digraphs

    Malekpour, Mahyar R.

    2011-01-01

    This report presents a self-stabilizing distributed clock synchronization protocol in the absence of faults in the system. It is focused on the distributed clock synchronization of an arbitrary, non-partitioned digraph ranging from fully connected to 1-connected networks of nodes while allowing for differences in the network elements. This protocol does not rely on assumptions about the initial state of the system, other than the presence of at least one node, and no central clock or a centrally generated signal, pulse, or message is used. Nodes are anonymous, i.e., they do not have unique identities. There is no theoretical limit on the maximum number of participating nodes. The only constraint on the behavior of the node is that the interactions with other nodes are restricted to defined links and interfaces. We present an outline of a deductive proof of the correctness of the protocol. A model of the protocol was mechanically verified using the Symbolic Model Verifier (SMV) for a variety of topologies. Results of the mechanical proof of the correctness of the protocol are provided. The model checking results have verified the correctness of the protocol as they apply to the networks with unidirectional and bidirectional links. In addition, the results confirm the claims of determinism and linear convergence. As a result, we conjecture that the protocol solves the general case of this problem. We also present several variations of the protocol and discuss that this synchronization protocol is indeed an emergent system.

    2017-01-01

    Full Text Available Negotiation of identities in communication entails affirming the identities we want others to recognize in us and ascription of identities we mutually assign to each other in communication. The study of intercultural communication focuses on cultural identity as the principal identity component that defines intercultural communication. In this article, the assumption that cultural group membership factors determine the context of intercultural communication is questioned. The article examines how intercultural interlocutors negotiate their identities in various intercultural interactions. The aims of the research presented in this paper are: 1 to examine which identities - cultural, personal, or social - intercultural interlocutors activate in intercultural communication; 2 to determine whether interlocutors’ intercultural communication is largely influenced by their cultural identities; 3 and to identify situations in which they activate their cultural identities (3. The research data were collected from 263 international students studying at Masaryk University in Brno in the years 2010 - 2016. Although the research results are not conclusive, they indicate that cultural identities predominate in the students’ ethnocentric views and that stereotypes constrain the students’ cultural identities and affect the negotiation of identities in intercultural communication.

    People can use their web browser or mobile devices to access web services and applications which are built into these servers. Users have to input their identity and password to login the server. The identity and password may be appropriated by hackers when the network environment is not safe. The multiple secure authentication protocol can improve the security of the network environment. Mobile devices can be used to pass the authentication messages through Wi-Fi or 3G networks to serve as a second communication channel. The content of the message number is not considered in a multiple secure authentication protocol. The more excessive transmission of messages would be easier to collect and decode by hackers. In this paper, we propose two schemes which allow the server to validate the user and reduce the number of messages using the XOR operation. Our schemes can improve the security of the authentication protocol. The experimental results show that our proposed authentication protocols are more secure and effective. In regard to applications of second authentication communication channels for a smart access control system, identity identification and E-wallet, our proposed authentication protocols can ensure the safety of person and property, and achieve more effective security management mechanisms.

  5. Comparative Associations Between Achieved Bicultural Identity, Achieved Ego Identity, and Achieved Religious Identity and Adaptation Among Australian Adolescent Muslims.

    Abu-Rayya, Hisham M; Abu-Rayya, Maram H; White, Fiona A; Walker, Richard

    2018-04-01

    This study examined the comparative roles of biculturalism, ego identity, and religious identity in the adaptation of Australian adolescent Muslims. A total of 504 high school Muslim students studying at high schools in metropolitan Sydney and Melbourne, Australia, took part in this study which required them to complete a self-report questionnaire. Analyses indicated that adolescent Muslims' achieved religious identity seems to play a more important role in shaping their psychological and socio-cultural adaptation compared to adolescents' achieved bicultural identity. Adolescents' achieved ego identity tended also to play a greater role in their psychological and socio-cultural adaptation than achieved bicultural identity. The relationships between the three identities and negative indicators of psychological adaptation were consistently indifferent. Based on these findings, we propose that the three identity-based forces-bicultural identity development, religious identity attainment, and ego identity formation-be amalgamated into one framework in order for researchers to more accurately examine the adaptation of Australian adolescent Muslims.

  6. Post-secretory fate of host defence components in mucus.

    Science.gov (United States)

    Salathe, Matthias; Forteza, Rosanna; Conner, Gregory E

    2002-01-01

    Airway mucus is a complex mixture of secretory products that provide a multifaceted defence against infection. Among many antimicrobial substances, mucus contains a peroxidase identical to milk lactoperoxidase (LPO) that is produced by goblet cells and submucosal glands. Airway secretions contain the substrates for LPO, namely thiocyanate and hydrogen peroxide, at concentrations sufficient for production of the biocidal compound hypothiocyanite, a fact confirmed by us in vitro. In vivo, inhibition of airway LPO in sheep significantly inhibits bacterial clearance, suggesting that the LPO system is a major contributor to host defences. Since secretory products including LPO are believed to be steadily removed by mucociliary clearance, their amount and availability on the surface is thought to be controlled solely by secretion. In contrast to this paradigm, new data suggest that LPO and other substances are retained at the ciliary border of the airway epithelium by binding to surface-associated hyaluronan, thereby providing an apical, fully active enzyme pool. Thus, hyaluronan, secreted from submucosal gland cells, plays a previously unrecognized pivotal role in mucosal host defence by retaining LPO and possibly other substances important for first line host defence at the apical surface 'ready for use' and protected from ciliary clearance.

  7. Practicing Identity: A Crafty Ideal?

    Science.gov (United States)

    Brysbaert, A.; Vetters, M.

    This paper focuses on the materialization of technological practices as a form of identity expression. Contextual analyses of a Mycenaean workshop area in the Late Bronze Age citadel of Tiryns (Argolis, Greece) are presented to investigate the interaction of different artisans under changing socio-political and economic circumstances. The case study indicates that although certain technological practices are often linked to specific crafts, they do not necessarily imply the separation of job tasks related to the working of one specific material versus another. Shared technological practices and activities, therefore, may be a factor in shaping cohesive group identities of specialized artisans. Since tracing artisans' identities is easier said than done on the basis of excavated materials alone, we employ the concepts of multiple chaînes opératoires combined with cross-craft interactions as a methodology in order to retrieve distinctive sets of both social and technological practices from the archaeological remains. These methodological concepts are not restricted to a specific set of steps in the production cycle, but ideally encompass reconstructing contexts of extraction, manufacture, distribution and discard/reuse for a range of artefacts. Therefore, these concepts reveal both technological practices, and, by contextualising these technological practices in their spatial layout, equally focus on social contacts that would have taken place during any of these actions. Our detailed contextual study demonstrates that the material remains when analysed in their entirety are complementary to textual evidence. In this case study they even form a source of information on palatial spheres of life about which the fragmentary Linear B texts, so far, remain silent.

  8. Host-specific interactions with environmental factors shape the distribution of symbiodinium across the Great Barrier Reef.

    Linda Tonk

    Full Text Available The endosymbiotic dinoflagellates (genus Symbiodinium within coral reef invertebrates are critical to the survival of the holobiont. The genetic variability of Symbiodinium may contribute to the tolerance of the symbiotic association to elevated sea surface temperatures (SST. To assess the importance of factors such as the local environment, host identity and biogeography in driving Symbiodinium distributions on reef-wide scales, data from studies on reef invertebrate-Symbiodinium associations from the Great Barrier Reef (GBR were compiled.The resulting database consisted of 3717 entries from 26 studies. It was used to explore ecological patterns such as host-specificity and environmental drivers structuring community complexity using a multi-scalar approach. The data was analyzed in several ways: (i frequently sampled host species were analyzed independently to investigate the influence of the environment on symbiont distributions, thereby excluding the influence of host specificity, (ii host species distributions across sites were added as an environmental variable to determine the contribution of host identity on symbiont distribution, and (iii data were pooled based on clade (broad genetic groups dividing the genus Symbiodinium to investigate factors driving Symbiodinium distributions using lower taxonomic resolution. The results indicated that host species identity plays a dominant role in determining the distribution of Symbiodinium and environmental variables shape distributions on a host species-specific level. SST derived variables (especially SSTstdev most often contributed to the selection of the best model. Clade level comparisons decreased the power of the predictive model indicating that it fails to incorporate the main drivers behind Symbiodinium distributions.Including the influence of different host species on Symbiodinium distributional patterns improves our understanding of the drivers behind the complexity of Symbiodinium

    We present a case of dissociative identity disorder in which Schneiderian first rank symptoms were present besides of various states of consciousness. Thus the diagnosis of schizophrenia had to be considered. Formally, the symptoms met ICD-10 criteria for schizophrenia. However, taking into account the lack of formal thought disorder and of negative symptoms as well as a typical history of severe and prolonged traumatisation, we did not diagnose a co-morbid schizophrenic disorder. There is good evidence for the existence of psychotic symptoms among patients with dissociative disorders. However, in clinical practice this differential diagnosis is rarely considered.

    Full Text Available We presented a model which describes the field of questions on identity as a field of dynamics. It is structured by means of particular, temporal configurations of identity through time and space. The theory of dynamic systems provides us with precise models for the representation of forms of identity, or of their evolution towards types of so-called chaos, given certain conditions. The model allows us to work in a comparative perspective, which is a sure advantage in conflict analysis. The complexity of identity phenomena is captured covering individual, group and community dynamics of identity.

    This paper aims to present a perspective to better understand corporate identity through examining the perceptions of Turkish patients and develop a corporate visual identity scale. While there is no study related to corporate identity research on hospitals in Turkey as a developing country, understanding consumer's perceptions about corporate identity efforts of hospitals could provide different perspectives for recruiters. When the hospitals are considered in two different groups as university and state hospitals, the priority of the characteristics of corporate visual identity may change, whereas the top five characteristics remain the same for all the hospitals.

    2007-10-01

    CERN, the European Organization for Nuclear Research, has operated an institutional preprint repository for more than 10 years. The repository contains over 850,000 records of which more than 450,000 are full-text OA preprints, mostly in the field of particle physics, and it is integrated with the library's holdings of books, conference proceedings, journals and other grey literature. In order to encourage effective propagation and open access to scholarly material, CERN is implementing a range of innovative library services into its document repository: automatic keywording, reference extraction, collaborative management tools and bibliometric tools. Some of these services, such as user reviewing and automatic metadata extraction, could make up an interesting testbed for future publishing solutions and certainly provide an exciting environment for e-science possibilities. The future protocol for scientific communication should guide authors naturally towards OA publication, and CERN wants to help reach a full open access publishing environment for the particle physics community and related sciences in the next few years.

    The outcome of a bacterial infection depends on the interaction between pathogen and host. The ability of the microbe to survive in the host depends on its invasive potential (i.e. spreading and multiplication), and its ability to obtain essential nutrients and to resist the host's defense system. On the other hand, the host's resistance to a bacterial attack depends on its physiological state, the intensity of the bacterial attack and the efficacy of the defense system to ...

  1. The idealization of origins among immigrants or exiled: the double function of maintaining identity and acculturation

    2014-07-01

    Full Text Available In the case of emigrated or exiled individuals, the idealization of origins often becomes more marked in the beginning of the integration of these individuals in the host society. Thus, as they lose their language, their customs, to take those of the society of reception, they elaborate an idealized image of their past. This progressive differentiation between the idealized past and the actual reality facilitates the acculturation in the host society and at the same time allows for the preservation of their specific identity. It is this elaboration of the ideal and its emancipation of the daily realities, which will be approached here.

  2. Home and away: hybrid perspective on identity formation in 1.5 and second generation adolescent immigrants in Israel.

    Full Text Available Immigration is not only about changing countries, but also about shifting identities. This change is especially important for adolescents. This article examines identity formation among 1.5 and 2nd generation adolescent immigrants to Israel. A survey of 125 children of immigrants aged 12-19 examined the role of social structures such as pace of life, culture, religion and language on identity formation in 1.5 and 2nd generational groups. We have identified several significant factors affecting the identities of children of migrants in each group. Looking beyond self-labeling, we argue that identity formation among children of immigrants is a continuous process in which the host country and origin country, both or neither of them, create dynamic hybrid patterns of identifications.

  3. Differential recognition and hydrolysis of host carbohydrate antigens by Streptococcus pneumoniae family 98 glycoside hydrolases.

    The presence of a fucose utilization operon in the Streptococcus pneumoniae genome and its established importance in virulence indicates a reliance of this bacterium on the harvesting of host fucose-containing glycans. The identities of these glycans, however, and how they are harvested is presently unknown. The biochemical and high resolution x-ray crystallographic analysis of two family 98 glycoside hydrolases (GH98s) from distinctive forms of the fucose utilization operon that originate from different S. pneumoniae strains reveal that one enzyme, the predominant type among pneumococcal isolates, has a unique endo-beta-galactosidase activity on the LewisY antigen. Altered active site topography in the other species of GH98 enzyme tune its endo-beta-galactosidase activity to the blood group A and B antigens. Despite their different specificities, these enzymes, and by extension all family 98 glycoside hydrolases, use an inverting catalytic mechanism. Many bacterial and viral pathogens exploit host carbohydrate antigens for adherence as a precursor to colonization or infection. However, this is the first evidence of bacterial endoglycosidase enzymes that are known to play a role in virulence and are specific for distinct host carbohydrate antigens. The strain-specific distribution of two distinct types of GH98 enzymes further suggests that S. pneumoniae strains may specialize to exploit host-specific antigens that vary from host to host, a factor that may feature in whether a strain is capable of colonizing a host or establishing an invasive infection.

  4. Recognizing Moral Identity as a Cultural Construct.

    Jia, Fanli; Krettenauer, Tobias

    2017-01-01

    Current research on moral identity shows that moral identity predicts moral action in Western cultures but not in non-Western cultures. The present paper argues that this may be due to the fact that the concept of moral identity is culturally biased. In order to remedy this situation, we argue that researchers should broaden their scopes of inquiry by adding a cultural lens to their studies of moral identity. This change is important because although some concept of moral identity likely exists in all cultures, it may function in different ways and at different levels in each place. We propose that moral identity is a context-dependent construct tied to varying social and cultural obligations. We argue that Western moral identity stresses an individually oriented morality, whereas, people from Eastern cultures consider a highly moral person to be societally oriented. We conclude by discussing the implications of this view for future research.

  7. Men, masculine identities and childbirth.

    2011-11-01

    In recent years, fathers' experiences during childbirth have attracted much research and policy interest. However, little of this work has been grounded in the first-hand accounts of men and there is a lack of theory-based research to help understand men's thoughts and practices around childbirth. This paper is based on qualitative research undertaken with first-time fathers and healthcare professionals. It draws on Connell's (1995) conceptualisation of hegemonic masculinity to explore how men construct masculine identities within the context of pregnancy and childbirth and also how healthcare professionals construct masculinity. The paper demonstrates the ways in which men can find themselves marginalised within the context of pregnancy and childbirth, but are still able to draw on identifiable markers of masculine practice which enable them to enact a masculine form congruent with dominant masculinity. It also illustrates how healthcare professionals' constructions of masculinity enable them to predict how men will behave and allow them to position men in ways that involve minimum disruption to their own practice. The paper also highlights how men's marginal status is embedded in the dynamics of the social structure, which produce and reproduce dominant masculine identities within the context of childbirth. © 2011 The Authors.

    Full Text Available The paper begins with a review of theoretical aspects including a conceptual delimitation of the term “economic globalization” from the perspective of different theorists, its main features, dimensions and vectors that boost and promote the process expansion. The phenolmenon is extensive, complex and difficult to control, fact that includes in this “wave” of globalization advantages and disadvantages also.The globalization of the economic activity is studied through globalization indicators such as: FDI, financial dimension, the role of transnational economic actors in the global economy, the relationship between international trade growth and increased domestic production, internationalization of the financial markets. The structure of the global economic system and the problems that the current global economy is facing are also analysed.The “thorny” subject of the influence that globalization has on national identity from an economic perspective is seen through the eyes of Romania, analyzing the economic implications of globalization for our country, how much the identity of Romanian companies was affected over the last years, which are now the Romanian multinationals and what challenges and opportunities globalization has brought to the country that was written with envy during the interwar period that is has “oil and wheat”.

  9. Postmodernist Identity Construction and Consumption

    Full Text Available Abstract. With the transition from modernism to postmodernism, identity as a concept has started to become redefined in sociology literature. The aim of this study is to show that postmodernism and symbolic interactionism are fused together to delineate both the scene as well as an actor’s identity. In that way, the interaction of a social structure with a culture that won’t be completely ignored, and, with the opinion that the categorized roles can skillfully be shaped and diversified by actors, it is possible to refrain from a pure determinism. But the transformation to enter different roles lacks meaning. Individuals pay more attention to their appearance more than who they are in order to be accepted by each group. In this manner, a metaphysical shell game begins. In the following study, the “Social Appearance Anxiety” was used as an indicator of this game.  And to determine who is willing to play the game, cultural parameters were utilized.       This study was based on the analysis of the data collected through two questionnaires given to 181 students studying at Hitit University. The INDCOL questionnaire [Singelis et al., 1995] measuring cultural values and “Social Appearance Anxiety” scale developed by [Hart, 2008] were used in the study.

    Men who have sex with men (MSM) remain at high risk for HIV infection. Culturally specific sexual identities, encompassing sexual roles, behavior, and appearance, may shape MSM's experiences of stigmatization and discrimination, and affect their vulnerability to HIV. This multi-site qualitative study (n = 363) encompassing 31 focus group discussions (FGDs) and 121 in-depth interviews (IDIs) across 15 sites in India investigated sexual identity formation, identity practices, and transitions and their implications for HIV prevention. IDIs and FGDs were transcribed, translated, and underwent thematic analysis. Our findings document heterogeneous sexual identity formation, with MSM who have more gender nonconforming behaviors or appearance reporting greater family- and community-level disapproval, harassment, violence, and exclusion. Concealing feminine aspects of sexual identities was important in daily life, especially for married MSM. Some participants negotiated their identity practices in accordance with socioeconomic and cultural pressures, including taking on identity characteristics to suit consumer demand in sex work and on extended periods of joining communities of hijras (sometimes called TG or transgender women). Participants also reported that some MSM transition toward more feminine and hijra or transgender women identities, motivated by intersecting desires for feminine gender expression and by social exclusion and economic marginalization. Future studies should collect information on gender nonconformity stigma, and any changes in sexual identity practices or plans for transitions to other identities over time, in relation to HIV risk behaviors and outcomes.

    Full Text Available This paper is aim to propose a data-origin authentication protocol based on ONOS cluster. ONOS is a SDN controller which can work under a distributed environment. However, the security of an ONOS cluster is seldom considered, and the communication in an ONOS cluster may suffer from lots of security threats. In this paper, we used a two-tier self-renewable hash chain for identity authentication and data-origin authentication. We analyse the security and overhead of our proposal and made a comparison with current security measure. It showed that with the help of our proposal, communication in an ONOS cluster could be protected from identity forging, replay attacks, data tampering, MITM attacks and repudiation, also the computational overhead would decrease apparently.

    Hypersensitivity reaction (HSR) to antineoplastic drugs can force doctors to stop treatment and seek other alternatives. These alternatives may be less effective, not as well tolerated and/or more expensive. Another option is to use desensitization protocols that induce a temporary state of tolerance by gradually administering small quantities of the antineoplastic drug until the therapeutic dosage is reached. The aim of this study is to assess the effectiveness of oxaliplatin desensitization protocols. A retrospective observational study was carried out between January 2006 and May 2011. The inclusion criteria were patients undergoing chemotherapy treatment with oxaliplatin who had developed an HSR to the drug and who were candidates for continuing the treatment using a desensitization protocol. The patients' clinical records were reviewed and variables were gathered relating to the patient, the treatment, the HSR, and the desensitization protocol administered. The data were analysed using version 18.0 of the statistics program SPSS. A total of 53 desensitization protocols were administered to 21 patients. In 89 % of these cases, no new reactions occurred while the drug was being administered. New reactions of mild severity only occurred in 11 % of cases, and none of these reactions were severe enough for treatment to be stopped. All patients were able to complete the desensitization protocol. This study confirms that oxaliplatin desensitization protocols are safe and effective and allow patients to continue with the treatment that initially caused an HSR.

    In this paper we present a protocol for the implementation of a positive-operator-valued measure (POVM) on massive fermionic qubits. We present methods for implementing nondispersive qubit transport, spin rotations, and spin polarizing beam-splitter operations. Our scheme attains linear opticslike control of the spatial extent of the qubits by considering ground-state electrons trapped in the minima of surface acoustic waves in semiconductor heterostructures. Furthermore, we numerically simulate a high-fidelity POVM that carries out Procrustean entanglement distillation in the framework of our scheme, using experimentally realistic potentials. Our protocol can be applied not only to pure ensembles with particle pairs of known identical entanglement, but also to realistic ensembles of particle pairs with a distribution of entanglement entropies. This paper provides an experimentally realizable design for future quantum technologies.

    A body sensor network (BSN) is a network of sensors deployed on a person's body for health care monitoring. Since the sensors collect personal medical data, security and privacy are important components in a BSN. In this paper, we developed IBE-Lite, a lightweight identity-based encryption suitable for sensors in a BSN. We present protocols based on IBE-Lite that balance security and privacy with accessibility and perform evaluation using experiments conducted on commercially available sensors.

    A multiparty simultaneous quantum identity authentication protocol based on Greenberger–Horne–Zeilinger (GHZ) states is proposed. The multi-user can be authenticated by a trusted third party (TTP) simultaneously. Compared with the scheme proposed recently (Wang et al 2006 Chin. Phys. Lett. 23(9) 2360), the proposed scheme has the advantages of consuming fewer quantum and classical resources and lessening the difficulty and intensity of necessary operations. (general)

  19. A Self-Stabilizing Hybrid Fault-Tolerant Synchronization Protocol

    Science.gov (United States)

    Malekpour, Mahyar R.

    2015-01-01

    This paper presents a strategy for solving the Byzantine general problem for self-stabilizing a fully connected network from an arbitrary state and in the presence of any number of faults with various severities including any number of arbitrary (Byzantine) faulty nodes. The strategy consists of two parts: first, converting Byzantine faults into symmetric faults, and second, using a proven symmetric-fault tolerant algorithm to solve the general case of the problem. A protocol (algorithm) is also present that tolerates symmetric faults, provided that there are more good nodes than faulty ones. The solution applies to realizable systems, while allowing for differences in the network elements, provided that the number of arbitrary faults is not more than a third of the network size. The only constraint on the behavior of a node is that the interactions with other nodes are restricted to defined links and interfaces. The solution does not rely on assumptions about the initial state of the system and no central clock nor centrally generated signal, pulse, or message is used. Nodes are anonymous, i.e., they do not have unique identities. A mechanical verification of a proposed protocol is also present. A bounded model of the protocol is verified using the Symbolic Model Verifier (SMV). The model checking effort is focused on verifying correctness of the bounded model of the protocol as well as confirming claims of determinism and linear convergence with respect to the self-stabilization period.

    The Special Monitoring of Applied Response Technologies (SMART) is a written dispersant effectiveness monitoring protocol developed in the United States in the mid 1990s. It has been the subject of considerable review and research since its development. This paper reported on the 2007-2008 review of the SMART dispersant effectiveness monitoring protocol which involved the following 3 tasks: (1) stakeholders reviewed their experience with SMART and identified the key deficiencies in the current protocol, (2) the SMART monitoring experience gathered during dispersant effectiveness testing at the Ohmsett National Oil Spill Response Test Facility was reviewed to evaluate the usefulness of existing SMART decision criteria, (3) available commercial off-the-shelf instruments (COTS) were surveyed to identify the instruments that might be more effective or simpler to use than those presently in use. The review concluded that the three-tiered approach in SMART was appropriate, but better guidance was needed for users. In addition, the fluorometer historically used for monitoring of dispersed oil was found to have several operating challenges and should be replaced with more modern equipment. It was recommended that all U.S. government sponsored monitoring teams work with identical instruments and operating protocols. The COTS survey identified 6 potentially suitable submersible and field-portable fluorometers and three particle-size analyzers. 26 refs., 5 tabs., 1 fig

    Full Text Available Burkholderia cenocepacia is an opportunistic respiratory pathogen of individuals with cystic fibrosis (CF. It is one of the highly transmissible species of Burkholderia cepacia complex and very resistant to almost all the antibiotics. Approximately 1/3rd of B. cenocepacia infected CF patients go on to develop fatal ‘cepacia syndrome’. During the last two decades, substantial progress has been made with regards to evasion of host innate defense mechanisms by B. cenocepacia. Almost all strains of B. cenocepacia has capacity to survive and replicate intracellularly in both airway epithelial cells and macrophages, which are primary centennials of the lung and play a pivotal role in clearance of infecting bacteria. Some strains of B. cenocepaica, which express cable pili and the associated 22kDa adhesin are also capable of transmigrating across airway epithelium and persist in mouse models of infection. In this review, we will discuss how this type of interaction between B. cenocepacia and host may lead to persistence of bacteria and contribute to lung inflammation in CF patients.

  5. Robust Multi-unit Auction Protocol against False-name Bids

    Science.gov (United States)

    Yokoo, Makoto; Sakurai, Yuko; Matsubara, Shigeo

    This paper presents a new multi-unit auction protocol (IR protocol) that is robust against false-name bids. Internet auctions have become an integral part of Electronic Commerce and a promising field for applying agent and Artificial Intelligence technologies. Although the Internet provides an excellent infrastructure for executing auctions, the possibility of a new type of cheating called false-name bids has been pointed out. A false-name bid is a bid submitted under a fictitious name. A protocol called LDS has been developed for combinatorial auctions of multiple different items and has proven to be robust against false-name bids. Although we can modify the LDS protocol to handle multi-unit auctions, in which multiple units of an identical item are auctioned, the protocol is complicated and requires the auctioneer to carefully pre-determine the combination of bundles to obtain a high social surplus or revenue. For the auctioneer, our newly developed IR protocol is easier to use than the LDS, since the combination of bundles is automatically determined in a flexible manner according to the declared evaluation values of agents. The evaluation results show that the IR protocol can obtain a better social surplus than that obtained by the LDS protocol.

  6. Efficient Cooperative Protocols for Full-Duplex Relaying over Nakagami-m Fading Channels

    2015-02-24

    In this work, efficient protocols are studied for full-duplex relaying (FDR) with loopback interference over Nakagami-m block fading channels. Recently, a selective decodeand- forward (DF) protocol was proposed for FDR, and was shown to outperform existing protocols in terms of outage over Rayleigh-fading channels. In this work, we propose an incremental selective DF protocol that offers additional power savings, yet yields the same outage performance. We evaluate their outage performance over independent non-identically distributed Nakagami-m fading links, and study their relative performance in terms of the signal-to-noise ratio cumulative distribution function via closed-form expressions. The offered diversity gain is also derived. In addition, we study their performance relative to their half-duplex counterparts, as well as known non-selective FDR protocols. We corroborate our theoretical results with simulation, and confirm that selective cooperation protocols outperform the known non-selective protocols in terms of outage. Finally, we show that depending on the loopback interference level, the proposed protocols can outperform their half-duplex counterparts when high spectral efficiencies are targeted.

  10. Historic Cosmology Identity and Exploration

    Science.gov (United States)

    Nebergall, K.

    The role of the soul and spirit in the composition of human endeavour generally takes the form of motivational poster catch phrases or third-hand quotes. If the spirit equals the life of a creature, and one of the signs of life is locomotion, are humans not obliged by something even deeper than our humanity to explore the universe? This paper examines the roots and perspectives of our worldviews on identity, exploration, and the limitations and capacities of humanity. It will equip the reader to discuss the nature of exploration with audiences across a wide range of worldviews. Current cultures, regardless of religion or politics, are looped into a series of nihilistic patterns that must be broken by rediscovering our nature as living beings, and our obligations as human beings.

    The main argument in this paper is: In order to comprehend the ‘invisible’ conditions for forming motivation to participate in different kinds of learning activities (formal, non-formal and informal) in relation to work-life it is crucial to develop a dialectic concept of learner identity....... A concept enabling researcher in the field of work and learning to examine how the orientation toward learning activities are situated in and conditioned by specific work-life experiences. Based on a qualitative research-project (Kondrup 2012) the paper outlines how unskilled work forms a specific condition...... for engaging in learning. The aim of the project was to examine the challenges in order to fulfil the Danish national strategy on Lifelong learning and training for all. Danish as well as international research reveals that low skilled workers and workers in small and medium sized private companies tend...

    On 26 December 2012 President Cavaco Silva announced the creation of the Conselho da Diápora Portuguesa, an association of 300 “notable” (notáveis) Portuguese to be individually invited by the Council’s Board. Their function will be to service as lobbyists working to improve the country’s image...... to their relatives in Portugal as well as to the needs of the Portuguese Government. This initiative, however, is different; here, in addition to direct economic benefits that the Council’s members may provide, their identity itself as successful Portuguese is put into play. Using tools from discourse analysis...... of Portugal, Camões and the Portuguese Communities (10 June 2013).

    A higher dimensional frame formalism is developed in order to study implications of the Bianchi identities for the Weyl tensor in vacuum spacetimes of the algebraic types III and N in arbitrary dimension n. It follows that the principal null congruence is geodesic and expands isotropically in two dimensions and does not expand in n - 4 spacelike dimensions or does not expand at all. It is shown that the existence of such principal geodesic null congruence in vacuum (together with an additional condition on twist) implies an algebraically special spacetime. We also use the Myers-Perry metric as an explicit example of a vacuum type D spacetime to show that principal geodesic null congruences in vacuum type D spacetimes do not share this property

    This paper reviews the literature on the impact of medical school on personal development and consolidation of core identity. The limited literature relies on reports from medical students' journaling exercises, discussion groups, post-graduation surveys, and repeated personality testing. We review forces acting on medical students, with potential transforming effects. These forces include high external expectations and internal fear of superficial knowledge and skills, entry into the culture of medicine with its insider jargon and hierarchy, high academic workload, and the emotional burdens of confronting cadavers and death as well as bearing witness to patients' suffering. Potential developmental delay, emergence of substance abuse and hedonic acting out, cynicism, and loss of individual core values are possible consequences. Protections against these adverse outcomes include identification of strong mentors and role models, developing post-conventional morality and relativistic thinking, finding healthy coping strategies such as peer support, and remaining intellectually creative and personally reflective.

    The increase in the number of forensic genetic loci used for identification purposes results in infinitesimal random match probabilities. These probabilities are computed under assumptions made for rather simple population genetic models. Often, the forensic expert reports likelihood ratios, where...... published results accounting for close familial relationships. However, we revisit the discussion to increase the awareness among forensic genetic practitioners and include new information on medical and societal factors to assess the risk of not considering a monozygotic twin as the true perpetrator......, then data relevant for the Danish society suggests that the threshold of likelihood ratios should approximately be between 150,000 and 2,000,000 in order to take the risk of an unrecognised identical, monozygotic twin into consideration. In other societies, the threshold of the likelihood ratio in crime...

    The colonization of an exotic species by native herbivores is more likely to occur if that herbivore is a generalist. There is little information on the life-history mechanisms used by native generalist insects to colonize exotic hosts and how these mechanisms are affected by host properties. We examined the ability of the generalist seed beetle Stator limbatus Horn to colonize an exotic species. We compared its host preference, acceptability, performance, and egg size when ovipositing and developing on two native (Pithecellobium dulce (Roxb.) Benth and Senegalia riparia (Kunth)) and one exotic legume species (Leucaena leucocephala (Lam.)). We also analyzed the seed chemistry. We found that females recognize the exotic species as an unfavorable host for larval development and that they delayed oviposition and laid fewer and larger eggs on the exotic species than on the native species. Survivorship on the exotic host was 0%. Additionally, seeds of the native species contain five chemical compounds that are absent in the exotic species, and the exotic species contains three sterols, which are absent in the native legumes. Genetically based differences between beetles adapted to different hosts, plastic responses toward new hosts, and chemical differences among seeds are important in host colonization and recognition of the exotic host. In conclusion, the generalist nature of S. limbatus does not influence its ability to colonize L. leucocephala. Explanations for the colonization of exotic hosts by generalist native species and for the success of invasive species must be complemented with studies measuring local adaptation and plasticity.

    Since 1953, 150,000 Korean children have been adopted to 15 main host countries in the West. They constitute the largest international adoptee group worldwide. An adopted Korean movement has existed on an international level since the 1990s and is today trying to formulate an identity and community of its own beyond Western adoption ideology and Korean nationalism. Tobias Hübinette outlines the history of international adoption from Korea, Western and Korean perspectives on international adop...

    Mood disorders are highly prevalent in people with multiple sclerosis (MS). MS causes changes to a person's sense of self. The Social Identity Model of Identity Change posits that group membership can have a positive effect on mood during identity change. The family is a social group implicated in adjustment to MS. The objectives of this study were to investigate whether family identity can predict mood in people with MS and to test whether this prediction was mediated by social support and connectedness to others. This cross-sectional survey of 195 participants comprised measures of family identity, family social support, connectedness to others, and mood. Family identity predicted mood both directly and indirectly through parallel mediators of family social support and connectedness to others. Family identity predicted mood as posited by the Social Identity Model of Identity Change. Involving the family in adjustment to MS could reduce low mood.

    The Groningen protocol allows for the euthanasia of severely ill newborns with a hopeless prognosis and unbearable suffering. We understand the impetus for such a protocol but have moral and ethical concerns with it. Advocates for euthanasia in adults have relied on the concept of human autonomy, which is lacking in the case of infants. In addition, biases can potentially influence the decision making of both parents and physicians. It is also very difficult to weigh the element of quality of...
