Adding symbolic information to picture models: definitions and properties
2005
AbstractIn the paper we propose extensions of some picture models, such as colored, drawn and pixel pictures. Such extensions are conceived by observing that a picture may embed more information than the shape, such as colors, labels, etc., which can be represented by a symbol from an alphabet and can be associated to segments, points or pixels. New interesting issues derived from the introduction of symbols will be investigated together with some complexity and decidability questions for the proposed extensions.
The Effect of Textual Producer-Generated Descriptions on Demand of Mobile Applications
2017
We analyze the impact of different app description characteristics on app demand on the basis of panel data for six months and 1081 distinct apps. We use several text mining techniques in order to operationalize the descriptions’ textual characteristics. The extracted variables are then used in an econometric investigation to examine their impact on apps’ downloads. Our results provide evidence that app descriptions have an effect on demand. Apps with upfront price should be described in a neutral tone. Apps without an upfront price but with in-app purchase option should be offered with rather short descriptions that are written in a formal and subjective style. peerReviewed
Izvērtējošā leksika produktu aprakstos
2016
Izvērtējošā leksika, arī pasīzstama kā novērtēšana, ir specifiska pieeja, kas izmantota, lai izpētītu, aprakstītu un izskaidrotu kā valoda ir lietota, lai paustu kāda izvērtējumu attiecībā uz konkrētu fenomenu vai uzvedību, kā arī ieņemtu konkrētu nostāju attiecībā uz tekstā izteikto priekšlikumu. Novērtēšana ir viens no trim galvenajiem diskursa semantiskajiem resursiem, kas veido interpersonālu nozīmi, kopā ar ‘līdzdalību’ un ‘vienošanos’. Šī pētījuma mērķis ir izpētīt, kā dažāda izvērtējošā leksika izmantota produktu aprakstos, un kā pareizs izvērtējošās leksikas lietojums var tikt izmantots kā stratēģija, lai palielinātu tirdzniecību. Metodoloģija izmantota šajā pētījumā ir korpusa ling…
The genus Pleurotus in Italy
2015
On the basis of personal observations, herbarium specimens and, data reported in the literature the authors report morphological, ecological and distributive data on Pleurotus taxa from Italy. New descriptions are here provided based on the most distinctive-discriminating eco-morphological characters of twelve Pleurotus taxa.
Glimpses of the Hereafter in the Late-Medieval Thet Freske Riim
2014
The article analyzes a passage of the narrative poem Thet Freske Riim, one of the few non-legal texts preserved in Old Frisian. The passage in question is a digression describing the Joys of Heaven and the Horrors of Hell, which so far has attracted little attention in the scholarly literature on medieval accounts of the hereafter. The representations of the afterlife and its realms circulating in Medieval Europe draw inspiration from a wide body of both orthodox and apocryphal literature on ecstatic dreams, of which one of the most influential work is the Visio Sancti Pauli or Apocalypse of Paul. The study aims to identify – in the examined passage – themes and features of otherworldly lit…
Nad kartami prac profesora Witolda Mańczaka. Notatki z marginesów
2017
In the works written in the last period of his life, Professor Witold Mańczak often emphasized the need to formulate a criterion of truth in linguistics. He pursued it in textual reality (in “what is written and what is said”) and in statistical, frequentative and quantitative data which describe it. On the margin of this search, this author shares his own experiences in the field of ethnolinguistics, related to attempts to determine the actual (and, in this sense, true) ontological status of analyzed objects. He postulates that the diversification of the objects of analysis should be complemented by an adequate diversification of how their names are recorded in the narration, i.e. by a pre…
Spatio-Chromatic Adaptation via Higher-Order Canonical Correlation Analysis of Natural Images
2014
Independent component and canonical correlation analysis are two general-purpose statistical methods with wide applicability. In neuroscience, independent component analysis of chromatic natural images explains the spatio-chromatic structure of primary cortical receptive fields in terms of properties of the visual environment. Canonical correlation analysis explains similarly chromatic adaptation to different illuminations. But, as we show in this paper, neither of the two methods generalizes well to explain both spatio-chromatic processing and adaptation at the same time. We propose a statistical method which combines the desirable properties of independent component and canonical correlat…
«Il sunt si biaus que c'en est une mervoie a voir». Zoologie e teratologie nel Devisement dou monde
2016
L’articolo ha come oggetto le descrizioni animali e teratologiche del Devisement dou monde. In particolare, la fauna poliana con le sue estremizzazioni mostruose e meravigliose viene indagata sul doppio filo del testo franco-italiano del Devisement (accompagnato, laddove necessario, dall’ausilio delle redazioni toscana e latina) e dell’iconografia rappresentata dalle miniature contenute in quattro codici del Devisement/Milione (mss. Royal 19 D I, Bodley 264, BNF fr. 2810, Arsenal 5219). The present article investigates animal and teratological descriptions of theDevisement dou monde. Particularly, Marco Polo’s fauna and its monstrous and marvelous extremes are explored both in the Franco-It…
Cosmological perturbations in extended electromagnetism. General gauge invariant approach
2013
A certain vector-tensor (VT) theory is revisited. It was proposed and analyzed as a theory of electromagnetism without the standard gauge invariance. Our attention is first focused on a detailed variational formulation of the theory, which leads to both a modified Lorentz force and the true energy momentum tensor of the vector field. The theory is then applied to cosmology. A complete gauge invariant treatment of the scalar perturbations is presented. For appropriate gauge invariant variables describing the scalar modes of the vector field (A-modes), it is proved that the evolution equations of these modes do not involve the scalar modes appearing in General Relativity (GR-modes), which are…
Detecting couple therapy for depression with a method Couple Therapy Process Q-set (CTQS) : process-descriptions of two good and one poor outcome cas…
2013
Tämä pro gradu – tutkielma on osa Dialogiset ja narratiiviset prosessit masennuksen pariterapiassa – projektia (DINADEP), jonka tarkoituksena oli tutkia masennuksen pariterapiaa ja mahdollisia tekijöitä, jotka voisivat vaikuttaa sen lopputulokseen. Tämän tutkimuksen tarkoituksena oli selvittää, miten pariterapiaprosessia kuvaavaa Q-set-menetelmää (PTQS) voidaan käyttää masennuksen pariterapiaprosessien kuvailuun tutkimalla kolmea tapausta, joista kaksi oli hyvin onnistuneita hoitoja ja yksi oli huonosti onnistunut hoito. PTQS arvioi yhtä terapiaistuntoa kerrallaan ja analysoitaessa useita istuntoja, saadaan tarkka kuva koko prosessista. Toinen tutkimuksen tavoite oli tutkia, kuinka terapeut…
