The Gospel on the Margins: The Ideological Function of the Patristic Tradition on the Evangelist Mark
No full textIn spite of the virtually unanimous patristic opinion that the evangelist Mark was the interpreter of Peter, one of the most prestigious apostolic founding figures in Christian memory, the Gospel of Mark was mostly neglected in the patristic period. Not only is the text of Mark the least well represented of the canonical Gospels in terms of the number of patristic citations, commentaries and manuscripts, the explicit comments about the evangelist Mark reveal some ambivalence about its literary or theological value. In my survey of the reception of Mark from Papias of Hierapolis until Clement of Alexandria, I will argue that the reason why the patristic writers were hesitant to embrace the Gospel of Mark was that they perceived the text to be amenable to the Christological beliefs and social praxis of rival Christian factions. The patristic tradition about Mark may have little historical basis, but it had an important ideological function in appropriating the text in the name of an apostolic authority from the margins or periphery
Trade justice and individual consumption choices : Adam Smith's spectator theory and the moral constitution of the Fair Trade consumer
No full textA consistent theme of the existing literature is that fair trade consumption practices represent acts of justice. In this article I investigate such an equation from the perspective of the moral theory of Adam Smith. Smith explains the development of moral sensibilities via an imaginative act he calls `sympathy'. For Smith, justice prevails in interpersonal relationships in which the potential for one person to do harm to another is ruled out because their respective imaginations are in perfect accord, thus creating a situation of mutual sympathy. I advance two main conclusions. First, I argue that fair trade consumption is undoubtedly a moral act in the manner described by Smith, as it involves consumers responding to fair trade campaigns in order to trigger their moral sensibilities through exercising their imaginative faculties. Second, though, I argue that fair trade consumption is not specifically a moral act of justice in the manner described by Smith. The structure of fair trade invites the First World consumer to display sympathy for the Third World producer, but it provides no means for that sympathy to be reciprocated. As such, instances of genuine mutual sympathy do not arise. From a Smithian perspective, fair trade consumption practices are an act of beneficence rather than an act of justice. They thereby reside in the realm of private virtue rather than the realm of public duty, with significant implications for the way in which trade justice is conceptualized and studied in IPE

Performance measurement with loss aversion
No full textWe examine a simple measure of portfolio performance based on prospect theory, which captures not only risk and return but also reflects differential aversion to upside and downside risk. The measure we propose is a ratio of gains to losses, with the gains and losses weighted (if desired) to reflect risk-aversion for gains and risk-seeking for losses. It can also be interpreted as the weighted ratio of the value of a call option to a put option, with the benchmark as the exercise price. When applying the loss-aversion performance measure to closed-end funds, we find that it gives significantly different rankings from those of conventional measures (such as the Sharpe ratio, Jensen’s alpha, the Sortino ratio, and the Higher Moment measure), and gives the expected signs for the odd and even moments of tracking errors. However, loss-aversion performance is not more closely related to discounts on funds than are the conventional performance measures, so we have not found evidence that loss-aversion attracts investors to particular funds in the short-term
Analysis methods for energy dispersive X-ray diffraction patterns, U.S. Patent 6,118,850
No full textEnergy dispersive x-ray diffraction spectra are obtained from numerous volume elements within an object. A feature set such as a set of cepstrum coefficients is extracted from each spectrum and classified by a trained classifier such as a neural network to provide an indication of whether or not contraband such as explosives is present in the volume element. Indications for adjacent volume elements are evaluated in conjunction with one another, as by an erosion process, to suppress isolated indications and thereby suppress false alarms
Pricing multivariate currency options with copulas
No full textMultivariate options are widely used when there is a need to hedge against a number of risks simultaneously; such as when there is an exposure to several currencies or the need to provide cover against an index such as the FTSE100, or indeed any portfolio of assets. In the case of a basket option the payoff depends on the value of the entire portfolio or basket of assets where the basket is some weighted average of the underlying assets. The principal reason for using basket options is that they are cheaper to use for portfolio insurance than a corresponding portfolio of plain vanilla options on the individual assets. This cost saving depends on the correlation structure between the assets; the lower the correlation between currency pairs in a currency portfolio for instance, the greater the cost saving
Exploring the Constitutional Implications of the UK’s Contemporary Counter-Terrorism Response(s) through the Lens of ‘Political’ Constitutionalism
No full textDo unique mechanisms underlie the expression of attention problems in anxious and inattentive-impulsive youth?: implications for differential diagnosis and treatment
No full textAccumulating evidence suggests that unique mechanisms may underlie the expression of attention problems in youth Attention-Deficit/Hyperactivity Disorder (AD/HD) and anxiety disorders (e.g., AD/HD-Inattentive Type and Generalized Anxiety Disorder). Kendall (2000) proposed that anxiety may be associated predominantly with emotion-based “distortions” in cognitive processing (e.g., misappraisal of the social/interpersonal environment, attentional bias toward perceived threat/danger), while inattention in AD/HD youth may be linked to more global cognitive “deficiencies” (e.g., selective/sustained attention, inhibitory control; Barkley, 1997). The current study compared performance of anxious (ANX; n=21; 8-17 years), inattentive-impulsive (I-I; n=22, 9-16 years), and typically developing children (NC; n=22; 8-13 years) on neurocognitive tests of both general (Stroop Color-Word Test, SCW; Conners’ Continuous Performance Test, CPT) and emotion-based attentional processes (Emotional Stroop, ES; Faces Dot Probe Task, FDP). As hypothesized, I-I demonstrated poorer sustained attention and inhibitory control, as evidenced by lower CPT commission error raw scores, relative to ANX and NC, and a non-significant trend toward higher CPT omission error T-scores, relative to ANX. In addition, ANX demonstrated superior selective attention, relative to I-I, as indicated by higher SCW raw scores (i.e., more items completed in 45 seconds), higher SCW T-scores, and fewer SCW errors. As predicted, ANX demonstrated greater attentional bias toward threat cues, relative to I-I, as indicated by greater FDP bias scores in response to angry faces. No significant group differences were found in bias scores on happy or sad trials. In addition, ANX showed a trend toward significant “absolute bias” scores (i.e., relative to zero) in response to angry faces alone, suggesting a potential emotion-specific attentional bias toward threat cues in anxious youth; I-I exhibited an “absolute bias” toward sad faces, alone. ES bias scores were not significant and did not distinguish between groups. The findings provide initial evidence for the neuropsychological differentiation of attention problems in anxious (i.e., threat-related attentional bias) and inattentive-impulsive children (i.e., general selective/sustained attention), suggesting the potential utility of cognitive assessment as an aid for differential diagnosis and subsequent treatment of youth anxiety and AD/HD.Ph.D.Includes bibliographical references (p. 51-66)by Adam Scott Weissma
Histories of science fiction: The Challenge of Periodization in "The History of Science Fiction", by Adam Roberts
No full textO autor e crítico britânico Adam Roberts, em seu livro A verdadeira história da Ficção Científica, projeta o início da ficção científica (FC) para a Antiguidade Clássica. Esta resenha crítica pretende analisar a premissa histórica do autor tendo em vista o desafio da periodização essa espécie literária, contrastando com ideias críticas de Brian Aldiss, Gary Westfahl, James Gunn, Mark Bould e Sherryl Vint, sem esquecer de autorias brasileiras, como André Carneiro, Braulio Tavares, Raul Fiker e Roberto Causo, entre outras autorias. Ainda se analisará a premissa anglocêntrica de Roberts, ao não visibilizar contribuições científicas de civilizações árabes e ibéricas, entre outras, embora se frise a validade da obra para ampliar as perguntas críticas no estudo contemporâneo.The History of Science Fiction, by the British author and critic Adam Roberts, traces the beginnings of Science Fiction (SF) to Classical Antiquity. This critical review aims to analyze the author\u27s historical premise given the challenge of periodization of this literary genre, contrasting Robert’s ideas with critical thoughts by Brian Aldiss, Gary Westfahl, James Gunn, Mark Bould, and Sherryl Vint, without forgetting Brazilian contribution in this matter by André Carneiro, Braulio Tavares, Raul Fiker and Roberto Causo, among others. Roberts\u27 Anglocentric premise will also be analyzed, as he does not make visible the scientific contributions of Arab and Iberian civilizations, among others, although the importance of his work will be stressed in contemporary studies
Unconventional membranes for direct air carbon capture.
