Writer-as-narrator: engaging the debate around the (un)reliable narrator in memoir and the personal essay

Subjective and personal forms of nonfiction writing are enjoying exponential popularity in English language publishing currently, as an interested public engages with ‘true’ stories of society and culture. Yet a paradox exists at the centre of this form of writing. As readers, we want to know who the writer is and what she has to tell us. Yet as writers we use a persona, a constructed character, a narrator who is only partially the writer, to deliver the narrative. How is a writer able to convey ‘true’ stories that are inherently reliant on memory, within a constructed narrative persona?We find a ‘gap’ between the writer and the narrator/protagonist on the page, an empowered creative space in which composition occurs, facilitating a balance between the facts and lived experiences from which ‘true’ stories are crafted, and the acknowledged fallibility of human memory. While the gap between writer and writer-as-narrator provides an enabling space for creative composition, it also creates space for the perception of unreliability. The width of this gap, we argue, is crucial. Only if the gap is small, if writer and writer-as-narrator share a set of passionately held values, can the writer-as-narrator become a believable entity, satisfying the reader with the ‘truth’ of their story.

Lying about the price? Ultimatum bargaining with messages and imperfectly observed offers

We introduce the taxicab game, related to the ultimatum game and Gehrig et al.'s (2007) yes/no game. The proposer makes an offer, and simultaneously sends a cheap talk message indicating (possibly falsely) the amount of the offer. The responder observes the message with certainty and the offer with probability p before accepting or rejecting the offer. We investigate versions with p=. 0 and p=. 0.5 along with the ultimatum game as a baseline. Intuition and a model comprising both standard economic agents and others who dislike inequity, lies and lying provide clear predictions that our experimental results support. As the likelihood increases of offers being seen, the offers themselves increase, messages over-state them less, and responders are more likely to accept (even when the offer is unseen). Also, responders are more likely to accept after truthful messages than after lies or when no message is sent.

Sounding loneliness in under the skin

How one affectively sounds loneliness on screen is dependent on what instruments, melodies, voices and sound effects are used to create a sonic membrane that manifests as melancholy and malcontent. It is in the syncretic and synesthetic entanglement that sounding loneliness takes root. It is in the added value inherent in the “sound-image” – to draw upon Chion1 – that loneliness fully emerges like a black dahlia. So many lonely people, where do they all come from? And yet, as I will suggest, this sounding loneliness is not only textually specific, simply or singularly driven by narrative and generic concerns, but is historically contingent and nationally and culturally locatable. For example, the sounds of urban isolation of the American 1940s film noir are different from the Chinese peasant laments of Chen Kaige’s Yellow Earth (1984), or what I will presently argue are the British austere strings of sounding loneliness today. When one employs a “diagnostic critique”2, one undertakes to find the history in the text and the text in the history. It is in the interplay between sound and image that historical and political truth emerges. These contextualised and historicised soundings change across and within national landscapes and their related imaginings. We don’t just see the crumbling walls of the imagined nation state, but get to hear its desolate tunes: The Specials wailing “Ghost Town” – the anthem of/to Margaret Thatcher’s first wave of 1980s neo-liberalism – is a striking case in point. But what specifically is this contemporary “sounding loneliness”, and where does it come from? I would like to suggest that this age of loneliness is composed in, through and within the sonic vibrations found in the wretched politics of austerity. My case study will be the anomic soundings of Jonathan Glazer’s Under the Skin (2013).

6 million spam tweets: a large ground truth for timely Twitter spam detection

Twitter has changed the way of communication and getting news for people's daily life in recent years. Meanwhile, due to the popularity of Twitter, it also becomes a main target for spamming activities. In order to stop spammers, Twitter is using Google SafeBrowsing to detect and block spam links. Despite that blacklists can block malicious URLs embedded in tweets, their lagging time hinders the ability to protect users in real-time. Thus, researchers begin to apply different machine learning algorithms to detect Twitter spam. However, there is no comprehensive evaluation on each algorithms' performance for real-time Twitter spam detection due to the lack of large groundtruth. To carry out a thorough evaluation, we collected a large dataset of over 600 million public tweets. We further labelled around 6.5 million spam tweets and extracted 12 light-weight features, which can be used for online detection. In addition, we have conducted a number of experiments on six machine learning algorithms under various conditions to better understand their effectiveness and weakness for timely Twitter spam detection. We will make our labelled dataset for researchers who are interested in validating or extending our work.

The indetermination of senior (or the indetermination of Wagner) and Schmoller as a Social Economist

The propositions of pure economics, whatever be their generality and their truth, do not authorize normative concluaions, but cannot be ignored. The latter, namely what ought not to be done, is derivable from socio-economics. The derivation is to be qualified by the specificities of the case. I have called this the Indetermination of Senior; Wagner and Marshall were quite aware of it. The habit of ignoring it is the Ricardian Vice; Schmoller's fight may have been a reaction against the latter. The Methodenstreit was the first great paradigmatic conflict between pure and social economists.

The public choice sedition: variations on the theme of scientific warfare

Given a significant element of truth in "Public Choice", a modest element must be found when a similar approach is made to the behavior of economic scientists. Harry Johnson found this in "The Keynesian Revolution and the Monetarist Counter-Revolution". Following him, I find more in the Public Choice "Revolution" itself. The basic visions, assumptions and methods of the latter are appraised within its time-space stream. "Variations on a theme by Buchanan" or "The B- and F-Twist" could have been suggestive subtitles for this paper -- an embrycnic Economics of Knowledge, a complement to the Sociology of Knowledge.

Important, unimportant a critical anticipation of the assumptions of legal positivism in Alice in Wonderland

Almost a full century separates Lewis’ Alice in Wonderland (1865) and the second, lengthier and more elaborate edition of Hans Kelsen’s Pure Theory of Law (1960; first edition published in 1934). And yet, it is possible to argue that the former anticipates and critically addresses many of the philosophical assumptions that underlie and are elemental to the argument of the latter. Both texts, with the illuminating differences that arise from their disparate genre, have as one of their key themes norms and their functioning. Wonderland, as Alice soon finds out, is a world beset by rules of all kinds: from the etiquette rituals of the mad tea-party to the changing setting for the cricket game to the procedural insanity of the trial with which the novel ends. Pure Theory of Law, as Kelsen emphatically stresses, has the grundnorm as the cornerstone upon which the whole theoretical edifice rests2. This paper discusses some of the assumptions underlying Kelsen’s argument as an instance of the modern worldview which Lewis satirically scrutinizes. The first section (Sleepy and stupid) discusses Lewis critique of the idea that, to correctly apprehend an object (in the case of Kelsen’s study, law), one has to free it from its alien elements. The second section (Do bats eat cats?) discusses the notion of systemic coherence and its impact on modern ways of thinking about truth, law and society. The third section (Off with their heads!) explores the connections between readings of systems as neutral entities and the perpetuation of political power. The fourth and final section (Important, Unimportant) explains the sense in which a “critical anticipation” is both possible and useful to discuss the philosophical assumptions structuring some positivist arguments. It also discusses the reasons for choosing to focus on Kelsen’s work, rather than on that of Lewis’ contemporary, John Austin, whose The Province of Jurisprudence Determined (published in 1832) remains influential in legal debates today.

Why the ‘Rest’ doesn’t need foreign finance

The Rest will be able to catch up and grow faster than the West only if it goes against a “received truth”, namely that capital-rich countries should transfer their capital to capital-poor countries. This intuitive truth is the mantra that the West cites to justify its occupation of the markets of developing countries with its finance and its multinationals. Classical Developmentalism successfully criticized the unequal exchange involved in trade liberalization, but it didn’t succeed in criticizing foreign finance. This task has been recently achieved by New Developmentalism and its developmental macroeconomics, which shows that countries will invest and grow more if they don’t run current account deficits, even when these deficits are financed by foreign direct investment

A narratological analysis of D. M. Thoma`s: the white hotel (1981)

“A Narratological Analysis of D. M. Thomas’s The White Hotel (1981)” originated within a seminar on British Postmodernist Literature during the first Master’s Degree in “British and North-American Culture and Literature” (2001-04) at the Universidade da Madeira set up by the Department of English and German Studies. This dissertation seeks to present a narratological analysis of Thomas’s novel. The White Hotel stands as a paradigmatic example of the kind of literature that has dominated the British literary scene in the past three decades, commonly referred to as postmodernist fiction, owing to its formal craftsmanship (multiplicity of narrative voices and perspectives, mixing of differing genres and text types, inclusion of embedded narratives) alongside the handling of what are deemed as postmodernist topoi (the distinction between truth and lies, history and fantasy, fact and fiction, the questioning of the nature of aesthetic representation, the role the author and the reader hold in the narrative process, the instability of the linguistic sign, the notion of originality and the moral responsibility the author has towards his/her work), The narratological approach carried out in this research reveals that Thomas’s text constitutes an aesthetic endeavour to challenge the teleological drive that is inherent in any narrative, i. e., the inevitable progression towards a reassuring end. Hence, the subversion of narrative telling, which is a recurrent feature in Thomas’s remaining literary output, mirrors the contemporary distrust in totalising, hierarchised and allencompassing narratives. In its handling of historical events, namely of the Holocaust, The White Hotel invites us to reassess the most profound beliefs we were taught to take for granted: progress, reality and truth. In their place the novel proposes a more flexible conception of both the world and art, especially of literary fiction. In other terms, the world appears as a brutal chaotic place the subject is forced to adjust to. Accordingly, the literary work is deemed hybrid, fragmented and open. So as to put forth the above-mentioned issues, this research work is structured in three main chapters. The initial chapter – “What is Postmodernism?” – advances a scrutiny not only of the seminal but also of more recent studies on postmodernist literary criticism. Following this, in Chapter II – “Postmodernist British Fiction” – a brief overview of postmodernist British fiction is carried out, focusing on the fictional works that, in my opinion, are fundamental for the periodising of British postmodernism. In addition, I felt the need to include a section – “D. M. Thomas as a Postmodernist Novelist” – in which the author’s remaining literary output is briefly examined. Finally, Chapter III – “A Narratological Analysis of The White Hotel” – proposes a narratological analysis of the novel according to the particular Genettian analytical model. To conclude, my dissertation constitutes an approach to D. M. Thomas’s The White Hotel as a text whose very existence is substantiated in the foregrounding of the contingency of all discourses, meeting the postmodernist precepts of openness and subversion of any narrative that claims to be true, globalising and all-inclusive.

Application of ionospheric corrections in the equatorial region for L1 GPS users

In the absence of the selective availability, which was turned off on May 1, 2000, the ionosphere can be the largest source of error in GPS positioning and navigation. Its effects on GPS observable cause a code delays and phase advances. The magnitude of this error is affected by the local time of the day, season, solar cycle, geographical location of the receiver and Earth's magnetic field. As it is well known, the ionosphere is the main drawback for high accuracy positioning, when using single frequency receivers, either for point positioning or relative positioning of medium and long baselines. The ionosphere effects were investigated in the determination of point positioning and relative positioning using single frequency data. A model represented by a Fourier series type was implemented and the parameters were estimated from data collected at the active stations of RBMC (Brazilian Network for Continuous Monitoring of GPS satellites). The data input were the pseudorange observables filtered by the carrier phase. Quality control was implemented in order to analyse the adjustment and to validate the significance of the estimated parameters. Experiments were carried out in the equatorial region, using data collected from dual frequency receivers. In order to validate the model, the estimated values were compared with ground truth. For point and relative positioning of baselines of approximately 100 km, the values of the discrepancies indicated an error reduction better than 80% and 50% respectively, compared to the processing without the ionospheric model. These results give an indication that more research has to be done in order to provide support to the L1 GPS users in the Equatorial region.

Modifying the stochastic model to mitigate GPS systematic errors in relative positioning

The GPS observables are subject to several errors. Among them, the systematic ones have great impact, because they degrade the accuracy of the accomplished positioning. These errors are those related, mainly, to GPS satellites orbits, multipath and atmospheric effects. Lately, a method has been suggested to mitigate these errors: the semiparametric model and the penalised least squares technique (PLS). In this method, the errors are modeled as functions varying smoothly in time. It is like to change the stochastic model, in which the errors functions are incorporated, the results obtained are similar to those in which the functional model is changed. As a result, the ambiguities and the station coordinates are estimated with better reliability and accuracy than the conventional least square method (CLS). In general, the solution requires a shorter data interval, minimizing costs. The method performance was analyzed in two experiments, using data from single frequency receivers. The first one was accomplished with a short baseline, where the main error was the multipath. In the second experiment, a baseline of 102 km was used. In this case, the predominant errors were due to the ionosphere and troposphere refraction. In the first experiment, using 5 minutes of data collection, the largest coordinates discrepancies in relation to the ground truth reached 1.6 cm and 3.3 cm in h coordinate for PLS and the CLS, respectively, in the second one, also using 5 minutes of data, the discrepancies were 27 cm in h for the PLS and 175 cm in h for the CLS. In these tests, it was also possible to verify a considerable improvement in the ambiguities resolution using the PLS in relation to the CLS, with a reduced data collection time interval. © Springer-Verlag Berlin Heidelberg 2007.

Automated determination of the orientation of dust devil tracks in mars orbiter images

The paper presents and evaluates three methods for automatically estimating the main orientation of Martian dust devil tracks in MOC and HiRISE images. Inferring such information about dust devils from their tracks is important to better understand the near surface wind. The methods considered were based on gradient direction, directional openings and morphological granulometry. The accuracy of the methods was asserted by comparing the results to a set of directions estimated visually and assumed to be the ground truth. The higher accuracy was reached using directional openings. Besides, the directions inferred by this method were compared to those predicted by the GCM and the results agreed. © 2013 COSPAR.
