Empowerment or repression? Opening up questions of identification and surveillance in Brazil through a case of 'identity fraud'
A real but typical case of identity fraud is used to open up the complex web of identification systems in Brazil. It is argued that identification has two poles related to the nature of citizenshipârepression and inclusionâand that reactions from citizens to new identification schemes can be attributed to how they view the purpose of the cards in these terms. In Brazil, a sense of inclusion and citizenship based on a fear of anonymity and exclusion predominates leading to widespread support amongst even critics of state activities. However, this may be undermined by the lack of state preparation for an information society, particularly the absence of meaningful data protection laws
Fracture mechanics approach to design analysis of notches, steps and internal cut-outs in planar components
A new approach to the assessment and optimization of geometric stress-concentrating features is proposed on the basis of the correspondence between sharp crack or corner stressfield intensity factors and conventional elastic stress concentration factors (SCFs) for radiused transitions. This approach complements the application of finite element analysis (FEA) and the use of standard SCF data from the literature. The method makes it possible to develop closed-form solutions for SCFs in cases where corresponding solutions for the sharp crack geometries exist. This is helpful in the context of design optimization. The analytical basis of the correspondence is shown, together with the limits on applicability where stress-free boundaries near the stress concentrating feature are present or adjacent features interact. Examples are given which compare parametric results derived from FEA with closed-form solutions based on the proposed method. New information is given on the stress state at a 90° corner or width step, where the magnitude of the stress field intensity is related to that of the corresponding crack geometry. This correspondence enables the user to extend further the application of crack-tip stress-field intensity information to square-cornered steps, external U-grooves, and internal cut-outs
Comparative Morphology of the Penis and Clitoris in Four Species of Moles (Talpidae).
The penile and clitoral anatomy of four species of Talpid moles (broad-footed, star-nosed, hairy-tailed, and Japanese shrew moles) were investigated to define penile and clitoral anatomy and to examine the relationship of the clitoral anatomy with the presence or absence of ovotestes. The ovotestis contains ovarian tissue and glandular tissue resembling fetal testicular tissue and can produce androgens. The ovotestis is present in star-nosed and hairy-tailed moles, but not in broad-footed and Japanese shrew moles. Using histology, three-dimensional reconstruction, and morphometric analysis, sexual dimorphism was examined with regard to a nine feature masculine trait score that included perineal appendage length (prepuce), anogenital distance, and presence/absence of bone. The presence/absence of ovotestes was discordant in all four mole species for sex differentiation features. For many sex differentiation features, discordance with ovotestes was observed in at least one mole species. The degree of concordance with ovotestes was highest for hairy-tailed moles and lowest for broad-footed moles. In relationship to phylogenetic clade, sex differentiation features also did not correlate with the similarity/divergence of the features and presence/absence of ovotestes. Hairy-tailed and Japanese shrew moles reside in separated clades, but they exhibit a high degree of congruence. Broad-footed and hairy-tailed moles reside within the same clade but had one of the lowest correlations in features and presence/absence of ovotestes. Thus, phylogenetic affinity and the presence/absence of ovotestes are poor predictors for most sex differentiation features within mole external genitalia
From the 'cinematic' to the 'anime-ic': Issues of movement in anime
This is the author's accepted manuscript. The final published article is available from the link below.This article explores the way that movement is formally depicted in anime. Drawing on Thomas Lamarre's concepts of the `cinematic' and the `anime-ic', the article interrogates further the differences in movement and action in anime from traditional filmic form. While often considered in terms of `flatness', anime offers spectacle, character development and, ironically, depth through the very form of movement put to use in such texts.The article questions whether the modes of address at work in anime are unique to this form of animation.Taking into account how the terms `cinematic' and `anime-ic' can be understood (and by extension the cinematic and animatic apparatus), the article also begins to explore how viewers might identify with such images

Constraints on and of Dark Energy from High Redshift Gamma Ray Bursts
We extend the Hubble diagram up to using 63 gamma-ray bursts (GRBs)
via peak energy-peak luminosity relation (so called Yonetoku relation), and
obtain constraints on cosmological parameters including dynamical dark energy
parametrized by . It is found that
the current GRB data are consistent with the concordance model, (), within two sigma level.
Although constraints from GRBs themselves are not so strong, they can improve
the conventional constraints from SNeIa because GRBs have much higher
redshifts. Further we estimate the constraints on the dark-energy parameters
expected by future observations with GLAST (Gamma-ray Large Area Space
Telescope) and \swift by Monte-Carlo simulation. Constraints would improve
substantially with another 150 GRBs.Comment: 5 pages, 6 figures. Submitted tu MNRA
Magnetism in Carbon Structures
We discuss different magnetic phenomena observed in carbon-based structures,
in particular the diamagnetism, paramagnetism and ferromagnetism observed in
graphite, disordered carbon, fullerenes and irradiated carbon structures.Comment: 6 pages, 3 figures, to be published in the proceedings of JEMS04,

Modeling Systematicity and Individuality in Nonlinear Second Language Development: The Case of English Grammatical Morphemes
This article introduces two sophisticated statistical modeling techniques that allow researchers to analyze systematicity, individual variation, and nonlinearity in second language (L2) development. Generalized linear mixed-effects models can be used to quantify individual variation and examine systematic effects simultaneously, and generalized additive mixed models allow for the examination of systematicity, individuality,and nonlinearity within a single model. Based on a longitudinal learner corpus, this article illustrates the usefulness of these models in the context of L2 accuracy development of English grammatical morphemes. I discuss the strengths of each technique and the ways in which these techniques can beneïŹt L2 acquisition research, further highlighting the importance of accounting for individual variation in modeling L2 development.This is the author accepted manuscript.
