The identity of Sertularia reptans Linnaeus, 1758 (Bryozoa, Candidae)

This paper includes a reassessment of Scrupocellaria reptans (Linnaeus, 1758) (basionym Sertularia reptans), the lectotype of which is selected and figured from among herbarium-sheet specimens held at the Linnean Society of London. Material previously assigned to S. reptans was examined, providing morphological characteristics to distinguish Scrupocellaria ellisi n. sp. Scrupocellaria reptans has a geographically limited distribution in the United Kingdom, while S. ellisi is more widespread in the North Sea, Northeast Atlantic, Adriatic and Tasmania.

A new species of Paralychnophora (Asteraceae: Vernonieae), and comments on the identity of Paralychnophora bicolor

The type of Paralychnophora bicolor was found to represent another species recently described as P. santosii. The misapplication of the name P. bicolor is reviewed. Also, a new species is here proposed, P. glaziouana, for plants previously identified as P. bicolor, since the only available name, P. schwackei, is an illegitimate combination. A key to Paralychnophora is given.

Germline-Specific MATH-BTB Substrate Adaptor MAB1 Regulates Spindle Length and Nuclei Identity in Maize

Germline and early embryo development constitute ideal model systems to study the establishment of polarity, cell identity, and asymmetric cell divisions (ACDs) in plants. We describe here the function of the MATH-BTB domain protein MAB1 that is exclusively expressed in the germ lineages and the zygote of maize (Zea mays). mab1 (RNA interference [RNAi]) mutant plants display chromosome segregation defects and short spindles during meiosis that cause insufficient separation and migration of nuclei. After the meiosis-to-mitosis transition, two attached nuclei of similar identity are formed in mab1 (RNAi) mutants leading to an arrest of further germline development. Transient expression studies of MAB1 in tobacco (Nicotiana tabacum) Bright Yellow-2 cells revealed a cell cycle-dependent nuclear localization pattern but no direct colocalization with the spindle apparatus. MAB1 is able to form homodimers and interacts with the E3 ubiquitin ligase component Cullin 3a (CUL3a) in the cytoplasm, likely as a substrate-specific adapter protein. The microtubule-severing subunit p60 of katanin was identified as a candidate substrate for MAB1, suggesting that MAB1 resembles the animal key ACD regulator Maternal Effect Lethal 26 (MEL-26). In summary, our findings provide further evidence for the importance of posttranslational regulation for asymmetric divisions and germline progression in plants and identified an unstable key protein that seems to be involved in regulating the stability of a spindle apparatus regulator(s).

Hip-hop and Construction of Group Identity in a Stigmatized Area. : A Field Study regarding Cultural Capital among Roma Youths in Konik, Montenegro.

This research aimed for an extended knowledge and understanding of young people in stigmatized areas and their construction of group identity. With a focus on Roma youths in Konik, Montenegro, and their involvement in hip-hop we wanted to explore what this culture meant to them in relation to their context. An ethnographic approach was used in collecting the empirical data through observations, interpreting music lyrics and conducting qualitative semi-structured interviews. Five young Roma boys from Konik, all involved in hip-hop, were interviewed. Theoretical perspectives on identity, youth culture and stigmatization were central. In addition, Bourdieu���s theory regarding cultural capital was emphasized and connected to youths and hip-hop. The empirical material showed that involvement in hip-hop provided the Roma youths with a group identity that they referred to in positive terms. Contextual factors of stigmatization excluded the Roma group from the majority population and the engagement in hip-hop created a possibility for the youths to be someone. The cultural capital gained through hip-hop was not used to verify and legitimate an authentic Roma identity. It was rather a way for them to create boundaries towards the negative elements in their community.

Normalized Frobenius condition number of the orthogonal projections of the identity

<p>[EN]This paper deals with the orthogonal projection (in the Frobenius sense) AN of the identity matrix I onto the matrix subspace AS (A ? Rn&times;n, S being an arbitrary subspace of Rn&times;n). Lower and upper bounds on the normalized Frobenius condition number of matrix AN are given. Furthermore, for every matrix subspace S ? Rn&times;n, a new index bF (A, S), which generalizes the normalized Frobenius condition number of matrix A, is defined and analyzed...</p>

Gender and identity classi���cation for a naive and evolving system

<p>[EN]This paper does not propose a new technique for face representationorclassi���cation. Insteadtheworkdescribed here investigates the evolution of an automatic system which, based on a currently common framework, and starting from an empty memory, modi���es its classi���ers according to experience. In the experiments we reproduce up to a certain extent the process of successive meetings. The results achieved, even when the number of different individuals is still reduced compared to off-line classi���ers, are promising.</p>

Identity Provider Shibboleth per il servizio di federazione e Single Sign-On di Ateneo

L���universit�� di Bologna, da sempre attenta alle nuove tecnologie e all���innovazione, si �� dotata nel 2010 di un Identity Provider (IDP), ovvero un servizio per la verifica dell���identit�� degli utenti dell���organizzazione tramite username e password in grado di sollevare le applicazioni web (anche esterne all���organizzazione) dall���onere di verificare direttamente le credenziali dell���utente delegando totalmente la responsabilit�� sul controllo dell���identit�� digitale all���IDP. La soluzione adottata (Microsoft ADFS) si �� dimostrata generalmente semplice da configurare e da gestire, ma ha presentato problemi di integrazione con le principali federazioni di identit�� regionali e italiane (FedERa e IDEM) a causa di una incompatibilit�� con il protocollo SAML 1.1, ancora utilizzato da alcuni dei servizi federati. Per risolvere tale incompatibilit�� il "CeSIA ��� Area Sistemi Informativi e Applicazioni" dell���Universit�� di Bologna ha deciso di dotarsi di un Identity Provider Shibboleth, alternativa open source ad ADFS che presenta funzionalit�� equivalenti ed �� in grado di gestire tutte le versioni del protocollo SAML (attualmente rilasciato fino alla versione 2.0). Il mio compito �� stato quello di analizzare, installare, configurare e integrare con le federazioni IDEM e FedERa un���infrastruttura basata sull���IDP Shibboleth prima in test poi in produzione, con la collaborazione dei colleghi che in precedenza si erano occupati della gestione della soluzione Microsoft ADFS. Il lavoro che ho svolto �� stato suddiviso in quattro fasi: - Analisi della situazione esistente - Progettazione della soluzione - Installazione e configurazione di un Identity Provider in ambiente di test - Deploy dell���Identity Provider in ambiente di produzione

Who can (not) be Greek? Citizenship, Identity and Belonging among youth of sub-Saharan African background in Athens

���Who can be Greek?��� This was the question posed to the Greek society for the first time before the implementation of the Act 3838 in March 2010 which gave the right to access the Greek citizenship -under specific preconditions- to all children of legal migrants born or schooled in Greece. This change of the Nationality Code in order to include all those children was coincided by the economic crisis resulting into the rise of xenophobia, racism and extreme-right rhetoric. The outcome was the cancellation of the Act 3838 by the State Council in February 2013. Under this particular framework, the notions of identity and belonging formed among the youth of African background in Athens are explored. The ways those youngsters perceive not only themselves but also their peers, their countries of origin and the country they live in, are crucial elements of their self-identification. Researches have shown that the integration of the second generation is highly connected to their legal and social status. However, integration is a rather complex process, influenced and shaped by many variables and multiple factors. It is not linear; therefore, its outcomes are difficult to be predicted. Yet, I argue that citizenship acquisition facilitates the process as it transforms those children from ���aliens��� to ���citizens���. How these youngsters are perceived by the majority society and the State is one of the core questions of the research, focusing on the imposed dual ���otherness��� they are subject to. On the one hand, they have to deal with the ���otherness��� originating from the migrant status inherited to them by their parents, and on the other with the ���otherness��� deriving from their different phenotypic characteristics. Race matters and becomes a means of discrimination against youth of African background who are perceived as inassimilable and ���forever others���.

Identity formation at the beginning of the twenty-first century: Intersubjectivity, art, and medicine in Siri Hustvedt���s works

���Ich bin, weil du bist��� ��� so lautet eines der Schl��sselzitate in What I Loved, dem 2003 erschienenen dritten Roman der zeitgen��ssischen amerikanischen Autorin Siri Hustvedt. Die Bedeutung von Beziehung und Interaktion f��r die Identit��tsbildung spielt eine zentrale Rolle nicht nur in diesem Roman, sondern auch in ihrem Gesamtwerk, das vier Romane, ein memoir, drei Essay-Sammlungen und einen Lyrikband umfasst. Hustvedt erforscht die Identit��t als ein vielschichtiges Produkt bewusster und unbewusster Verkn��pfungen innerhalb der sozialen und biologischen Umwelt. Das Bewusstsein wird als eine dialogisch gepr��gte Entit��t gezeigt, dessen Identit��t erst durch die Beziehung auf ein Anderes geformt werden kann. Um dem Mysterium der menschlichen Identit��tsfindung nachzusp��ren, bedient sich Hustvedt sowohl philosophischer, psychoanalytischer, biologischer als auch kunsttheoretischer Diskurse. In ihren Romanen stellt sich die Frage nach der Erkl��rung von Identit��t als komplexe Problematik dar: Ist die Beziehung zu anderen Menschen vor allem durch unsere Entwicklung als Kind und die N��he zu Bezugspersonen gepr��gt? In welchem Ausma�� ist das Empfinden von Subjektivit��t beeinflusst von k��rperlichen und unbewussten Mechanismen? Inwiefern ist die Wahrnehmung visueller Kunst eine Kooperation zwischen Betrachter und K��nstler? rnDiesen und anderen Fragen geht diese Dissertation nach, indem sie Hustvedts Werk als Anlass f��r eine Analyse intersubjektiver Strukturen der Identit��t nimmt. Die Intersubjektivit��tsphiloso��phien von Hegel, Buber, Bakhtin, Husserl, und Merleau-Ponty dienen hierbei als Ausgangspunkt f��r die Interpretation von relationaler Identit��t in Hustvedts Werken. Die Dissertation konzentriert sich auf Hustvedts Darstellung der Beziehung zwischen Selbst und Anderem in der Photographie und in der Malerei, der ��berschreitung von K��rpergrenzen in Hysterie und Anorexie sowie der Auswirkung des Verlustes von Bezugspersonen auf die pers��nliche Identit��t. Entscheidend f��r den Hustvedtschen Kunstbegriff ist das Zusammenspiel von Kunstobjekt, K��nstler und Betrachter. Die Grenzen zwischen Innerem und ��u��eren werden aufgel��st: mal wird der Rezipient Teil des Kunstwerks, mal verschmilzt der K��nstler f��rmlich mit seinem Objekt. Auch hier wird wiederum deutlich, dass Identit��t nur in Wechselbeziehung und als zwischenmenschliche Kooperation entsteht. Hustvedt betritt durch ihre einzigartige Auseinandersetzung mit den Wechselbeziehungen und fragilen Grenzen zwischen Ich und Umwelt Neuland auf dem Gebiet der literarischen Identit��tsforschung, da sie ihr Prinzip des ���mixing,��� des unausweichlichen Eindringens fremder Substanz in die eigene Identit��t, aus dem Blickwinkel dieser verschiedenen Erkl��rungsans��tze beleuchtet. rn

Identity dynamics and the emergence of new organizational arrangements: A multi-level study

Organizational and institutional scholars have advocated the need to examine how processes originating at an individual level can change organizations or even create new organizational arrangements able to affect institutional dynamics (Chreim et al., 2007; Powell & Colyvas, 2008; Smets et al., 2012). Conversely, research on identity work has mainly investigated the different ways individuals can modify the boundaries of their work in actual occupations, thus paying particular attention to ���internal��� self-crafting (e.g. Wrzesniewski & Dutton, 2001). Drawing from literatures on possible and alternative self and on positive organizational scholarship (e.g., Obodaru, 2012; Roberts & Dutton, 2009), my argument is that individuals��� identity work can go well beyond the boundaries of internal self-crafting to the creation of new organizational arrangements. In this contribution I analyze, through multiple case studies, healthcare professionals who spontaneously participated in the creation of new organizational arrangements, namely health structures called Community Hospitals. The contribution develops this form of identity work by building a grounded model. My findings disclose the process that leads from the search for the enactment of different self-concepts to positive identities, through the creation of a new organizational arrangement. I contend that this is a particularly complex form of collective identity work because it requires, to be successful, concerted actions of several internal, external and institutional actors, and it also requires balanced tensions that ��� at the same time - enable individuals��� aspirations and organizational equilibrium. I name this process organizational collective crafting. Moreover I inquire the role of context in supporting the triggering power of those unrealized selves. I contribute to the comprehension of the consequences of self-comparisons, organizational identity variance, and positive identity. The study bears important insights on how identity work originating from individuals can influence organizational outcomes and larger social systems.

Identity Changes and Consumer Behavior. How Becoming Parents Changes Our Consumption Choices

This research aims at investigating the impact of the identity change on consumption. An identity change is defined as the acquisition of a new identity after a life change event. For instance after the birth of the first child the new identity as parent is acquired and a woman can define herself as a mother. Despite marketing research recognizes that individuals��� identity is unstable and susceptible to change, the investigation of the identity change is still in its infancy. Furthermore, marketing research did not investigate the contextual effect of the new as well as the old identity on individuals��� reaction toward identity-marketing. In order words, whether people show a more favorable reaction toward product related to their new or their old identities after an identity change is still unclear. In order to answer this question, five studies are conducted. Results show that when the new identity substitutes the old one, people show a more positive reaction toward new-identity related products, while when the new identity is added to the old ones, people show a more positive reaction toward old-identity related products. This is the case also when the new identity accounts for high levels of identification (study three) and when the old identity is squeezed by the new one (studies four and five). A new concept, the identity strain, is then introduced and discussed.
