Multivariate identification of functional neural networks underpinning humorous movie viewing
While univariate functional magnetic resonance imaging (fMRI) data analysis methods have been utilized successfully to map brain areas associated with cognitive and emotional functions during viewing of naturalistic stimuli such as movies, multivariate methods might provide the means to study how brain structures act in concert as networks during free viewing of movie clips. Here, to achieve this, we generalized the partial least squares (PLS) analysis, based on correlations between voxels, experimental conditions, and behavioral measures, to identify large-scale neuronal networks activated during the first time and repeated watching of three ∼5-min comedy clips. We identified networks that were similarly activated across subjects during free viewing of the movies, including the ones associated with self-rated experienced humorousness that were composed of the frontal, parietal, and temporal areas acting in concert. In conclusion, the PLS method seems to be well suited for the joint analysis of multi-subject neuroimaging and behavioral data to quantify a functionally relevant brain network activity without the need for explicit temporal models.
Souvent considéré comme une activité des plus nuisibles, le piratage des contenus audiovisuels n’en constitue pas moins, depuis des décennies, pour de nombreuses populations aux quatre coins du monde, un moyen majeur d’accéder aux produits des industries culturelles. Nourri d’enquêtes de terrain, cet ouvrage explore les enjeux que recèle ce phénomène complexe. Cette étude inédite analyse les stratégies globales de lutte contre le piratage, évalue les politiques des autorités nationales, décrit les usages que font les publics des contenus audiovisuels piratés, retrace les chemins qu’empruntent ces derniers et s’intéresse à ceux qui font le commerce de ces produits, de même qu’aux mutations engendrées par internet en la matière.
Comparison of the kernel effectiveness of SVM classifier to distinguish gender based on the structural connectome
The Incongruity Theory of Humor in its different forms states that the cause of laughter is the perception of something that violates our mental patterns and expectations. It seems particularly true of comic absurdity which is based on a deadpan violation of established norms of logic and convention. The current paper explores linguistic mechanisms that underlie the comic effects in the works of Mikhail Zoshchenko, one of the great satirists of Soviet Russia. Zoshchenko is well-known for his simplified writing style which imitates the language and mentality of “the simple people” while at the same time mocking the nascent Soviet officialdom and its demands for the popular accessibility of art. The paper considers Zoshchenko’s narrative through the prism of conventional implicatures (Grice 1961, Karttunen and Peters 1979, Horn 2004, Potts 2005, 2007), or meanings that are not directly stated in the utterances, but implied by the speaker; e.g. Even John solved the problem implies that it was it was not expected of John to solve it. In successful communication, implicit meanings form the shared background of conversational partners; violation of these shared norms may be used to create comical effect. One of the most conventionalized societal norms and one Zoshchenko most frequently violates is the value of human life and, hence, solemn attitude to death. The narrator in Zoshchenko’s stories repeatedly implies otherwise, thus creating a comical portrait of the mentality of Homo Soveticus. Consider a quote from “The story about a greedy dairy woman”: “So, her husband died. At first she probably took it lightly. - A-a, she thought – no big deal… But then she realized – yes, this is a big deal!... Eligible bachelors are not running around in bunches. And then, of course, she started grieving” (shift in emphasis; the cause for grief is not the husband’s death but its inconvenience for the surviving wife). The story “A restless old man” (about an old man who lives in a communal flat and falls into lethargic stupor taken by his family and neighbors for death and then after waking up really dies) is based on violating the same conventional implicature. Throughout the story the narrator implicitly creates the image of death as an inconvenient occurrence and of a deceased person as an unwanted piece of waste. The harshly comic effect is achieved by implicatures about the shallow emotional impact of death (“And then of course there is aggravation: because the room is small and here is a superfluous element”, “If my husband, this surviving idiot, ordered the hearse right away, then the wait for it would have only been three days”; “The summoned doctor reassured everybody that now the old man is bona fide dead”); by violation of semantic compatibility rules whereby the seemingly dead old man is alternately referred to as an animate being (“The dead man is lying and demanding the last tribute to be paid to him”, “The babysitter is afraid to be in the room where a dead person is living”) or inanimate object (“There is so little space that there is even nowhere to pile up the old man”; “I am going to pile him up in the hall, let him wait for the hearse there”).
The main stages in the development of prime-time entertainment on the national channels are described. The focus is on the four dominant formats which sequentially replaced one another throughout the 2000s. The processes thereby one format is displaced by another from prime time are examined. Basing on Yu. N. Tynyanov’s theory of literary genres evolution the author believes that a new replacing format arises as an opposition to the format that is being displaced. Within this framework comedy variety displaced quizzes and talent shows displaced musical realities.
In this paper the author analyses the materials that were pub- lished in the American satirical magazine The Onion in the period from 2006 till 2011 and mentioned September 11 terrorist attacks. The focus of the research is the persistence of 9/11 jokes five years after the tragedy occurred and later on. The jokes are classified basing on their subject-matter and rhetorical patterns. The author concludes that most of these jokes promote respect towards collective memory about the attacks and their victims.
The paper is based on the research that was funded by the Faculty of Philosophy of the National Research University Higher School of Economics in 2011.
We study dierences in structural connectomes between typically developing and autism spectrum disorders individuals with machine learning techniques using connection weights and network metrics as features. We build linear SVM classier with accuracy score 0:64 and report 16 features (seven connection weights and nine network node centralities) best distinguishing these two groups.
A model for organizing cargo transportation between two node stations connected by a railway line which contains a certain number of intermediate stations is considered. The movement of cargo is in one direction. Such a situation may occur, for example, if one of the node stations is located in a region which produce raw material for manufacturing industry located in another region, and there is another node station. The organization of freight traﬃc is performed by means of a number of technologies. These technologies determine the rules for taking on cargo at the initial node station, the rules of interaction between neighboring stations, as well as the rule of distribution of cargo to the ﬁnal node stations. The process of cargo transportation is followed by the set rule of control. For such a model, one must determine possible modes of cargo transportation and describe their properties. This model is described by a ﬁnite-dimensional system of diﬀerential equations with nonlocal linear restrictions. The class of the solution satisfying nonlocal linear restrictions is extremely narrow. It results in the need for the “correct” extension of solutions of a system of diﬀerential equations to a class of quasi-solutions having the distinctive feature of gaps in a countable number of points. It was possible numerically using the Runge–Kutta method of the fourth order to build these quasi-solutions and determine their rate of growth. Let us note that in the technical plan the main complexity consisted in obtaining quasi-solutions satisfying the nonlocal linear restrictions. Furthermore, we investigated the dependence of quasi-solutions and, in particular, sizes of gaps (jumps) of solutions on a number of parameters of the model characterizing a rule of control, technologies for transportation of cargo and intensity of giving of cargo on a node station.
Event logs collected by modern information and technical systems usually contain enough data for automated process models discovery. A variety of algorithms was developed for process models discovery, conformance checking, log to model alignment, comparison of process models, etc., nevertheless a quick analysis of ad-hoc selected parts of a journal still have not get a full-fledged implementation. This paper describes an ROLAP-based method of multidimensional event logs storage for process mining. The result of the analysis of the journal is visualized as directed graph representing the union of all possible event sequences, ranked by their occurrence probability. Our implementation allows the analyst to discover process models for sublogs defined by ad-hoc selection of criteria and value of occurrence probability
