description: According to recent theoretical studies, classical novae are expected to erupt every ~$10^5$ years, while the recurrence time scale of modern recurrent novae (N_r) stars ranges from 10 to ~100 years. To bridge this huge gap in our knowledge (three orders of magnitude in time scales), it appears attractive to consider historical data: In Far Eastern sources, we searched for brightening events at different epochs but similar positions that possibly refer to recurrent nova eruptions. Probing a sample of ~185 Asian observations from ~500 BCE to 1700 CE, we present a method to systematically filter possible events. The result are a few search fields with between 2 and 5 flare ups and typical cadences between $10^2$ and $10^3$ years. For most of our recurrence candidates, we found possible counterparts among known cataclysmic variables in the corresponding search areas. This work is based on an interdisciplinary approach, combining methods from digital humanities and computational astrophysics when applying our previously developed methods in searches for classical novae among Far Eastern guest stars. A first and rather preliminary comparison of (possible) historical and (well known) modern recurrent novae reveals first tentative hints on some of their properties, stimulating further studies in this direction.

Year: 2016

description: The study generates knowledge on the patterns, structures, and geography of growth of the cruise port industry in the Mediterranean and its adjoining seas. The analysis of the passenger movements in the period 2005-2014, as provided by cruise port authorities, details the port hierarchy and reveals transformation of the region from a cluster of port destinations hosting a certain thousands of cruise passengers to a multi-port cruise region accommodating several millions of passenger movements. An adapted application of the ‘multi-port region’ concept, originally developed in cargo port studies extends research to intra-region dynamics and exposes previously unexplored imbalances that co-exist with the overall growth of a commonly seen and homogeneous single cruise region. The picture completes with the examination of the unbalanced trends in the major 20 cruise ports in the Med, and the levels of market concentration. The findings call for similar analyses, and not least comparisons, with other regions. With Asia appearing in the strategies of cruise lines as a deployment region and a source market, and the Med experiencing volatile trends, they are also practically helpful for those involved in the development and management of cruise ports.

description: The mapping observations of CO $J=2-1$, CO $J=3-2$, $^{13}$CO $J=2-1$ and $^{13}$CO $J=3-2$ lines in the direction of IRAS 22506+5944 have been made. The results show that the cores in the $J=2-1$ transition lines have a similar morphology to those in the $J=3-2$ transition lines. Bipolar molecular outflows are verified. The prior IRAS 22506+5944 observations indicated that two IRAS sources and three H$_{2}$O masers were located close to the peak position of the core. One of the IRAS sources may be the driving source of the outflows. In addition, the H$_{2}$O masers may occur in relatively warm environments. The parameters of the dense core and outflow, obtained by the LTE method, indicate that IRAS 22506+5944 is a high-mass star formation region.

description: One of the most recent tactics to hit the financial markets in India is debt or asset securitization. Under asset securitization, a financial institution pools and packages individual loans and receivables creates securities against them, gets them rated, and sells them to the investors in the market, while the transactions involved during securitization attract taxation. Taxation issues surrounding securitization transactions have not been clearly clarified in the relevant tax laws in so far as regulations of securitizations are concerned (i.e., securitization transactions governed by RBI regulations or regulations of the Securities and Exchange Board of India (SEBI), the capital markets regulator). For instance, a lack of clarity in taxation provisions with respect to investment in the Security receipt (SRs) issued by the Asset Reconstruction Company (ARCs) is among the challenges. Moreover, Under the income-tax law, no specific tax rate is mentioned for the taxability of interest income or upside received by FPIs from their investment in the SRs. Thus, this study is a normative legal study that employs normative methods and looks for the provisions regarding the taxation of securitization transactions and its legal implications under Indian taxation regimes. Whereas provisions of tax statutes like the Income Tax Act and Stamp Duty Act are examined and analyzed in relation to other laws that govern securitization in India.

description: The first stage of tactile sensing is data acquisition using tactile sensors and the sensed data is transmitted to the central unit for neuromorphic computing. The memristive crossbars were proposed to use as synapses in neuromorphic computing but device intelligence at the sensor level are not investigated in literature. We propose the concept of Transistor Memristor Sensor (TMS)-crossbar by including sensor to memristor crossbar array configuration in the input layer of the neural network architecture. 2 possible cell configurations of TMS crossbar arrays: 1 Transistor 1 Memristor 1 Sensor (1T1M1S) and 2 Transistor 1 Memristor 1 Sensor (2T1M1S) are presented. We verified the proposed TMS-crossbar in the practical design of analog neural networks based Braille character recognition system. The proposed design is verified with SPICE simulations using circuit equivalent of FLX-A501 force sensor, TiO$_2$ memristors and low power 22nm high-k CMOS transistors. The proposed analog neuromorphic computing system presents a scalable solution and is possible to encode 125 symbols with good accuracy in comparison with other Braille character recognition systems in the literature. The benefits of analog implementation of the TMS crossbar arrays is substantiated with results of accuracy, area and power requirements in comparison with the binary counterparts.

Year: 2016

description: In the tourism development plans in Croatia and Serbia, rural tourism has a place of special importance. Taking into account the total population of rural areas, total surface area they occupy in these countries and the presence of diverse tourism potential (preserved nature and cultural heritage), rural tourism could become a powerful tool in achieving the goals of sustainable development of rural areas. Regardless of all social differences between Croatia and Serbia, it can be assumed that rural areas share common problems. They are exposed to depopulation, slow economic development and poorly developed infrastructure. There is a dilemma that raises the question of how much these two countries in their joint tourism development initiatives can contribute to resolving problems of rural areas, and in particular their border regions.

Investigating color variations due to precipitable water in Rubin-LSST Auxiliary telescope photometry
Creators: name: DAGORET, Sylvie
Publisher: name: Zenodo
Year: 2024

description: The Rubin-LSST observatory aims to achieve photometric accuracy better than 0.5 percent, even when photometric observation conditions are not met. To this end, the observatory has  commissioned an auxiliary telescope, Auxtel, whose function is to measure the air transparency  in parallel with the photometric observations of the main LSSTCam telescope. Nowadays Auxtel measures air-transparency routinely for which  example of inferred precipitable water vapour monitoring curves measured  are presented. These measurements are compared to variation in difference color curves between star pairs from Auxtel photometry. Despite the limited performances of Auxtel photometry possible correlation between those measurements paving the way to derive methods to derive colour compensation for LSST's photometry with Auxtel.
Still a perfect model? The gender impact of vocational training in Germany

description: Reconstructing the parallel structure of ‘dual’ and ‘school-based’ vocational routes reveals the close connection between the German vocational training system and the segmentation of the labour market by gender. The example of jobs in childcare and pre-primary education shows that the legacy of semi-professionalism in these occupations is not just rooted in the nature of training and working conditions, but complexly interlinks with the prevalence of the male breadwinner model sustained by social policy regulations and the German taxation system. In France, by contrast, the central state takes responsibility for the provision of childcare from zero to six years of age to support female labour force participation and dual-earner couples. This has also fostered professionalisation in the respective occupations. Whilst this may not necessarily induce a degendering process at the level of horizontal segregation of vocational qualiﬁcations, it facilitates gender equality in terms of vertical mobility and the professional status of women.

description: We consider a simple model of a cloud chamber consisting of a test particle (the alpha-particle) interacting with two other particles (the atoms of the vapour) subject to attractive potentials centered in $a_1, a_2 \in \mathbb{R}^3$. At time zero the alpha-particle is described by an outgoing spherical wave centered in the origin and the atoms are in their ground state. We show that, under suitable assumptions on the physical parameters of the system and up to second order in perturbation theory, the probability that both atoms are ionized is negligible unless $a_2$ lies on the line joining the origin with $a_1$. The work is a fully time-dependent version of the original analysis proposed by Mott in 1929.

description: Using B, R, and H-alpha images of roughly equal-sized samples of low surface brightness (LSB) and high surface brightness (HSB) galaxies (~40 galaxies apiece), we have explored the dependence of HII region properties on local and global disc surface brightness. We have done this by constructing co-added HII region luminosity functions (LFs) according to local and central disc surface brightness and fitting Schechter functions to these LFs. The results show that the shape of the HII region LF within LSB galaxies does not change noticeably as different limiting (i.e., mu>mu_lim) local surface brightness values are used. However, the LFs for HSB galaxies have larger values of L_* and are less steep at the faint-end than those of LSB galaxies for limiting B-band local surface brightness values as faint as mu_B,lim~23-24. Both the LFs and the data for individual HII regions show that luminous (log L>39 ergs/s) HII regions are much more common within HSB discs than within LSB discs, implying that the newly formed star clusters are also larger. Taking this into account along with the results of Monte Carlo simulations, the shapes of the LFs imply that the regions within LSB discs and those within the LSB areas of HSB discs are relatively old (~5 Myr) while the regions within HSB discs for mu_B<24 are significantly younger (<1 Myr). Since the majority of the LSB galaxies do not have noticeable spiral arms and the majority of the HSB galaxies do, this may indicate a transition within HSB discs from spiral arm-driven star formation to a more locally driven, possibly sporadic form of star formation at mu_B~24, a transition that does not appear to occur within LSB discs.

The signal with tri-lepton final states and large missing transverse energy is appropriate for studying collider signatures of the scenario with extra spatial dimensions. We show that the LHC experiment generally has a potential to discover the signs of extra dimensions and the origin of small neutrino masses.

Effects of low levels of ozone on plant populations
Creators: name: Bennett, James Peter
Publisher: name: University of British Columbia
Year: 2010

description: Recent evidence has shown that low levels of many air pollutants can now be measured almost anywhere on the earth's surface and that the concept of a "pollutant" is only relative to the dose received by the organism and/or the population. Although the range of sensitivity to air pollutants in plants is very broad, it is possible to hypothesize that a majority of plant species are able to adapt phenotypically and genotypically to these previously overlooked components of the atmosphere. To test this general hypothesis, a set of experiments was carried out to investigate adaptive mechanisms in plant form, efficiency, and competitive ability in annual ryegrass and crimson clover populations exposed to filtered air, .03 and .09 ppm O₃ daily during the vegetative phase of growth. Allometric analysis showed that the root systems of these plants were the organs most sensitive to the O₃ treatments, possibly due to impaired translocation of growth substances from the stressed aerial portion of the plant. In addition, the strategy of using new photosynthetic products for expanding the assimilatory apparatus or directing those products to other metabolic or reproductive activities was not affected by the O₃ treatments used in these experiments. Growth analysis of the aerial portion of these plants revealed that overall efficiency (Relative Growth Rate and Crop Growth Rate) was not impaired by the low O₃ treatments at either the individual plant or crop stand levels because inverse compensating adjustments occurred between the relative size of the assimilatory system (Leaf Area Ratio or Leaf Area Index, which consistently decreased) and the system's photosynthetic efficiency (Unit Leaf Rate, which often increased in O₃). In plant competition experiments using deWit replacement series at a constant density (mixtures) and in monocultural spacing experiments, ryegrass displayed an innate ability to occupy more space than clover under O₃ stress and this effect (an increase of about one tiller/plant) was enhanced by the presence of clover in the mixtures. Although fewer tillers/ plant were produced in the mixtures, the increase in tillering due to O₃ was greater than in the monocultures. This unexpected result was corroborated by a close agreement between predicted and observed ryegrass crowding coefficients in the high O₃ treatment, good agreement between two separate runs of the same experiment, and agreement of the observed equilibrium ratio in high O₃ (2 clover : 1 ryegrass) with the field seeding ratio. It is concluded that these pasture species during their vegetative growth phase, exposed daily to low ambient levels of O₃, do not show seriously impaired growth or qualitative changes in mixture, but that plant form and the relative size of the plant system is decreased, suggesting that phenotypic and genotypic adaptations take place more at the morpho-genetic level of plant organization than at the population or community level.

description: Η μεταφορά των στερεών θραυσμάτων του σχηματισμού που δημιουργούνται κατά τη διαδικάσια μίας γεώτρησης είναι από τις σημαντικότερες παραμέτρους σχεδιασμού σε γεωτρήσεις πετρελαίου και Φυσικού Αερίου σε μεγάλα βάθη. Η μεταφορά και απομάκρυνσή τους από το φρεάτιο επιτυγχάνεται με τη χρήση διατρητικής λάσπης (πολφού) με κατάλληλα ρεολογικά και φυσικοχημικά χαρακτηριστικά, ώστε να διασφαλίζεται παράλληλα η δομική ακεραιότητα  των τοιχωμάτων του φρεατίου και του σχηματισμού, καθώς και η αντιστάθμιση των πιέσεων πόρων. Ειδικότερα σε οριζόντιες γεωτρήσεις δημιουργούνται συνθήκες διαχωρισμού του αιωρήματος λάσπης και συσσώρευσης των θραυσμάτων στο κατώτερο τμήμα του φρεατίου με αποτέλεσμα την ανάπτυξη ισχυρότερων τάσεων στην περιστρεφόμενη στήλη αλλά και τη μερική απόφραξή του. Στο πλαίσιο της διπλωματικής εργασίας μελετήθηκαν πειραματικά οι συνθήκες μεταφοράς θραυσμάτων σε μία πιλοτική μονάδα δακτυλιοειδούς αγωγού. Η μελέτη αποκάλυψε τρεις βασικούς μηχανισμούς μεταφοράς που μελετήθηκαν πειραματικά ως προς τις συνθήκες ανάπτυξής τους και το βαθμό καθαρισμού που επιτυγχάνουν. Με βάση τα παραπάνω αναπτύχθηκαν διάγραμματα φάσεων για διάφορες τιμές ιξώδους για τυπικούς πολφούς διάτρησης. Τα αποτελέσματα των πειραμάτων έδειξαν ότι όσο πιο λεπτόρρευστο το ρευστό τόσο καλύτερα γίνεται η μεταφορά των θραυσμάτων.

description: We look at the wetting of a pure fluid in contact with a charged flat surface. In the bulk, the fluid is a classical van der Waals fluid containing dissociated ions. The presence of wall and ions leads to strong dielectrophoretic and electrophoretic forces that increase the fluid's density at the wall. We calculate the fluid's profiles analytically and numerically and obtain the energy integrals. The critical surface potential for prewetting is obtained. In the phase diagrams, the line of first-order transition meets a second-order transition line at a critical point whose temperature can be higher or lower than the bulk critical temperature. The results are relevant to droplet nucleation around charged particles in the atmosphere and could possibly explain deviations from expected nucleation rates.

description: In the current context of social arrhythmia promoted by the culture of excess, consumerism and individualism the purpose of this article is to discuss the need to promote changes in tourism and society towards a more human development, based on the pillars of the solidarity economy. The article extends discussions on the solidarity economy into the context of classical economics, with new offers and demands that are focused not on capital accumulation only, but on the rights and development of human beings. To achieve this goal, we analyse four key foundations of the solidarity economy - solidarity, social equality, cooperation and sharing. The original contribution of the paper is to present cutting-edge ideas that show a counterpoint to capitalism and consumerism; one that is excluded from global tourism’s contradictory path by a form of production that values social relations, and quality of life in community experiences and community tourism.

description: This paper investigates the cause and effect of crises on tourism destination image and the international tourists’ travel motivation. Structural Equation Modeling (SEM) procedures were performed to achieve the research goals. Through series of empirical analyses, some useful insights on the issue investigated were obtained. The findings revealed that there are three types of crises; sustained, an immediate and emerging crisis which affect the image of a tourism destination and subsequently influence the tourist travel motivation. In fact, the immediate and emerging crises, although was found to negatively affecting the image of tourism destination, does not inhibit the international tourists travel motivation. The result of this study shows varying consequences and implications of crises to individual tourist, tourism intermediaries, tourism agencies, government authorities and any parties related to tourism industry.

description: Tacit knowledge is a concept developed in connection with knowledge management research field. It is acknowledged as the cornerstone of competitive advantage; however, merely its possession does not guarantee an edge in fierce competition. Even though tacit knowledge holds a dominative role towards labor efficiency, productivity and innovation, the subject of tacit knowledge acquisition and transfer has been rather unexploited, mostly due to its intrinsic, highly personal and seamlessly bonded to holder’s personality, attributes. The purpose of the article is to contribute to the exploitation of the embedded tacit knowledge of employees in hospitality establishments, a sector where the employment of tacit knowledge has to be extensive and foremost, capitalizing the maximum of personnel competences. Towards this goal, research hypotheses were built and tested, using SEM Methodology. The final outcome of the study revealed that task assignment customized to employees’ personality and emotions is directly and positively correlated with tacit knowledge transfer.

description: The larvae of the black soldier fly (BSFL), Hermetia illucens L. (Diptera: Stratiomyidae), are of economic interest due to their use as livestock feed component. Unraveling their response to a bacterial infection will allow us to gain a better insight into their biology. In the current study, we used RNA-Seq analysis to unravel the transcriptomic response of BSFL to wounding and infection by a Gram-negative bacterium, Pseudomonas protegens Pf-5. Five-day-old BSFL were subjected to three treatments, i.e. untreated, PBS-injection, and bacteria-injection (5000 CFU per larva) and samples were collected at three time points (2 h, 6 h, and 13 h) post- treatment. Wounding induced expression of genes encoding pathogen recognition molecules and signaling pathway genes such as PGRP-SA, and Relish, and antimicrobial peptides (AMPs) such cecropin, defensin, and attacin. At 2 h, wounding resulted in a significant upregulation of immunity-related genes whereas genes encoding for resilin and cuticle proteins were significantly downregulated. At 6 h, the expression of immunity-related genes reduced in response to wounding whereas their expression increased in infected larvae. At 13 h, the expression of immunity-related genes reduced drastically in response to wounding, while their expression increased significantly in infected larvae. Conversely, the expression of metabolism-related genes, such as trypsin and chymotrypsin, was significantly upregulated in wounded larvae at 13 h, while their expression was significantly reduced in infected larvae. Increased investments in immunity-related processes in infected BSF larvae correlated with the downregulation of genes associated with metabolic processes indicative of a trade-off. Various immunity-related genes, including those encoding cecropin, defensin, attacin, and PGRP-SA, were consistently induced only during pathogen infection, indicating their role in immunity against Gram-negative bacteria. In this study, we report multiple genes that are significantly upregulated post-bacterial infection in BSFL that may be utilized as biomarkers to monitor insect health in mass production facilities.

description: We study the prospects for detecting neutrino masses from the galaxy angular power spectrum in photometric redshift shells of the Dark Energy Survey (DES) over a volume of 20 (Gpc/h)^3 combined with the Cosmic Microwave Background (CMB) angular fluctuations expected to be measured from the Planck satellite. We find that for a Lambda-CDM concordance model with 7 free parameters in addition to a fiducial neutrino mass of M_nu = 0.24 eV, we recover from DES &Planck the correct value with uncertainty of +- 0.12 eV (95 % CL), assuming perfect knowledge of the galaxy biasing. If the fiducial total mass is close to zero, then the upper limit is 0.11 eV (95 % CL). This upper limit from DES &Planck is over 3 times tighter than using Planck alone, as DES breaks the parameter degeneracies in a CMB-only analysis. The analysis utlilizes spherical harmonics up to 300, averaged in bin of 10 to mimic the DES sky coverage. The results are similar if we supplement DES bands (grizY) with the VISTA Hemisphere Survey (VHS) near infrared band (JHK). The result is robust to uncertainties in non-linear fluctuations and redshift distortions. However, the result is sensitive to the assumed galaxy biasing schemes and it requires accurate prior knowledge of the biasing. To summarize, if the total neutrino mass in nature greater than 0.1eV, we should be able to detect it with DES &Planck, a result with great importance to fundamental Physics.

This problem was cured by a simple modification of the `shape function', which introduces a new parameter $m\ge 2$ ($m=2$ corresponds to the EB model). This leads to a generalised (GEB) version. In this work, we consider a model where the GEB wormhole geometry is embedded in a five dimensional warped background. We studied the status of all the energy conditions in detail for both EB and GEB embedding. We present our results analytically (wherever possible) and graphically. Remarkably, the presence of decaying warp factor leads to satisfaction of weak energy conditions even for the EB geometry, while the status of all the other energy conditions are improved compared to the four dimensional scenario. Besides inventing a new way to avoid the presence of exotic matter, in order to form a wormhole passage, our work reveals yet another advantage of having a warped extra dimension.

description: We consider the behavior of classical and quantum oscillations in metals with complex Fermi surfaces near the directions of $\, {\bf B} \, $ corresponding to changes in the topological structure of the dynamical system describing the semiclassical motion of quasiparticles along the Fermi surface. The transitions through the boundaries of change in this structure are accompanied by sharp changes in the picture of oscillations, the form of which depends in the most essential way on the topological type of the corresponding reconstruction. We list here the main features of such changes for all topological types of elementary reconstructions and discuss the possibilities of experimental identification of such types based on these features.

Huellas que no se borran. Ruptura y desdoblamiento psíquico en tres obras de Luisa Valenzuela
Creators: name: Medeiros-Lichem, María Teresa,
Publisher: name: Università degli  Studi di Milano
Year: 2014
Subjects: Luisa Valenzuela; desdoblamiento psíquico; desplazamiento; memoria; Argentina

description: The emotional rupture caused by experiences of repression, displacement and exile originates a dislocation in the identity of the subject which often leads into a schizophrenic search for a new identity.  In the process of adaptation to the new condition the characters often unfold into split subjects which cause them to act irrationally.
This essay will explore the psychic transformations suffered by characters in their efforts to reconstitute a coherent and stable self in three works by Luisa Valenzuela: Novela negra con argentinos (1990), “Tiempo de retorno” (2008), and Realidad nacional desde la cama (1990). Her characters are split between the external reality and a repressed trauma, a situation where Memory and the wish to erase an unspeakable past strive to arouse into the surface of consciousness. Valenzuela’s protagonists are driven by the hidden desire to reach the Secret of their desolation. The true re-encounter and reconstitution of the Self will only be possible after the recognition of the indelible traces engraved in the collective Memory.

description: Given a diagonalizable $N\times N$ matrix $H$, whose non-degenerate spectrum consists of $p$ pairs of complex conjugate eigenvalues and additional $N-2p$ real eigenvalues, we determine all metrics $M$, of all possible signatures, with respect to which $H$ is pseudo-hermitian. In particular, we show that any compatible $M$ must have $p$ pairs of opposite eigenvalues in its spectrum so that $p$ is the minimal number of both positive and negative eigenvalues of $M$. We provide explicit parametrization of the space of all admissible metrics and show that it is topologically a $p$-dimensional torus tensored with an appropriate power of the group $Z_2$.

description: Time-irreversibility is a distinctive feature of non-equilibrium dynamics and several measures of irreversibility have been introduced to assess the distance from thermal equilibrium of a stochastically driven system. While the dynamical noise is often approximated as white, in many real applications the time correlations of the random forces can actually be significantly long-lived compared to the relaxation times of the driven system. We analyze the effects of temporal correlations in the noise on commonly used measures of irreversibility and demonstrate how the theoretical framework for white noise driven systems naturally generalizes to the case of colored noise. Specifically, we express the auto-correlation function, the area enclosing rates, and mean phase space velocity in terms of solutions of a Lyapunov equation and in terms of their white noise limit values.

An intelligent management information system as a test of a formal accounting theory
Creators: name: Clarke, Bevan J.
Publisher: name: University of British Columbia
Year: 2010

description: An 'automated accountant' or 'robot bookkeeper' is implemented. This is capable of deducing accounting entries and updating an accounting model of the world. It is given as input a narrative or dialogue in ordinary idiomatic English. This empirical project is a focus around which we study the possibility of an IMIS, an 'Intelligent Management Information System'. Under this heading three avenues of research into what Mattessich calls the 'instrumental sciences' are unified. They are (a) The Intelligent MIS per se: an application of research into so-called Artificial Intelligence to the development of the computerized Management Information System. We consider that if computers and their software are to be employed reliably in very complex systems it will become necessary for the design of such a system, its adaptation to changing circumstances and the management of the organization via the computer all to be integrated and directed largely by, the computer itself. In its ultimate form the IRIS would use the deductive and inductive formalisms of Artificial Intelligence to pursue top management objectives delegated to it. (b) The methodology of the instrumental sciences: we review the merits of the axiomatic method of scientific theory construction. Instrumental disciplines, such as accountancy, appear to call for extensions to scientific logic, notably in the direction of non-declarative logics. (c) We examine the value of implementation as part of a test of formal theory, specifically Ijiri's axiomatized accounting theory. At the sane time we employ his axioms as the enspiriting knowledge of our accourting robot. We find that when elaborated to the point where it may be used successfully to deduce accourting conclusions via a computer program the theory bears a closer resemblance to Mattessich's axiomatized theory. Such an attempted refutation is interesting in its own right. Moreover, since the management of accounting information may be regarded as a core of an MIS, it is suggested that if theoretical accounting may be successfully implemented as the guiding knowledge of an IMIS this may lead to the elaboration in a similar style of an implementable theoretic foundation for Management Information Systems.
Terms for Canadian doctors : language and sociology, ethnosemantics and ethnomethodology
Creators: name: Eglin, Peter Anthony
Publisher: name: University of British Columbia
Year: 2010

description: In trying to discover the nature of cultural competence, ethno-semantics leaves out of account the judgemental or interpretive work of a society's members, and that neglect is fatal to its programme. This critical thesis is the nub of the dissertation. The latter is constructed as an argument, and is organized in two parts as follows. The first part is programmatic. After an introduction (Chapter One), three kinds of sociology are introduced and formally described (Chapter Two). Ethnosemantics and ethnomethodology are cast as "grammatical" and "interpretive" sociology respectively (Chapter Three). This enables us, in pursuing a methodological critique of ethnosemantics from a position based in ethnomethodology (Chapter Four), to draw conclusions about sociology (Chapter Five): insofar as "positivistic" sociology presupposes "grammatical" sociology which presupposes "interpretive" sociology, then (1) "positivistic" explanation is not, in principle, superior to commonsense explanation, (2) an adequate sociology needs be interpretive, and (3) ethnosemantics, in engaging in what ethnomethodology calls "constructive analysis", fails to be an adequate sociology. The second part is empirical. The argument is now pursued in terms of data from a study of terms for Canadian doctors. After an introduction (Chapter Six), the methods and results of the ethnosemantic part of the study are presented (Chapter Seven). These results are then critically examined in the light of an ethnomethodological analysis of the interviews which generated them (Chapter Eight). It is concluded (Chapter Nine) that ethnosemantics, in relying on the very competence it is trying to explicate, fails to make that resource a topic, and thereby fails to render an adequate analysis of its intended object. In contrast, ethnomethodology provides both the missing analysis and an account of ethnosemantics' failure.
La voce del trauma. Il caso di Petra Soukupová
Creators: name: Bratankova, Leontyna
Publisher: name: Firenze University Press
Year: 2014
Subjects: Czech contemporary literature; Czech language; family dimension; trauma

description: This article deals with the Czech novel Zmizet (Disappearing, 2009) written by the young writer Petra Soukupová (1982) and winner of the prestigious literary prize Magnesia Litera (2010). The novel handles the personal trauma of its characters in their own family context. It is made up of three short stories whose main characters are children. Each story represents an instance of the traumatic event and its implications as possible ways of facing it. This analysis focuses on the main narrative elements used by the writer to express the psychological dimension of characters. It also investigates the language used by the author which successfully leads readers deep into the inner dimension of the novel’s protagonists.
