Due to the inherent chaotic and fractal dynamics in the price series of Bitcoin, this paper proposes a two-stage Bitcoin price prediction model by combining the advantage of variational mode decomposition and technical analysis. VMD eliminates the noise signals and stochastic volatility in the price data by decomposing the data into variational mode functions, while technical analysis uses statistical trends obtained from past trading activity and price changes to construct technical indicators. The support vector regression accepts input from a hybrid (...) of technical indicators and reconstructed variational mode functions. The model is trained, validated, and tested in a period characterized by unprecedented economic turmoil due to the COVID-19 pandemic, allowing the evaluation of the model in the presence of the pandemic. The constructed hybrid model outperforms the single SVR model that uses only TI and rVMF as features. The ability to predict a minute intraday Bitcoin price has a huge propensity to reduce investors’ exposure to risk and provides better assurances of annualized returns. (shrink)

Socio-cultural changes in the pattern of development of a group of people often occur when there is an introduction of foreign cultures. The annexation of Gold Coast brought the Asante Empire under British rule, and from the beginning of the twentieth century Gold Coast witnessed a total transformation of the economy from it subsistence nature to a cash economy. Economic changes associated with diversification and rapid expansion of Gold Coast export mitigated for a demand in labour force. However, the (...) research focused on the people of Kumasi and using the Winick theory of alcohol dependency sought to unveil the socio-cultural changes that occurred within the period under review. Furthermore, with the use of qualitative narrative, interviews, secondary and primary data, the research was undertaken and findings revealed some changes in customs, values, and lifestyle of individuals in the community. It further indicated the role played by colonial influence and administration’s reliance on imported alcohol coupled with the introduction of a new kind of local gin (akpeteshie). It was also discovered that, European influence contributed greatly to changes that occurred in the social and cultural uses of distilled liquor in Kumasi. European liquor came to be identified with modernity and European lifestyle. Furthermore, the introduction of railway transport, road transport and creation of urbanization by colonial government policies promoted a new form of social drinking notable among the youth which was devoid of any form of restrain by elders and chiefs. In addition, there was the emergence of social classes who appreciated the European way of life and drinking because it depicted prestige wealth. On the other hand, the emergence of akpeteshie promoted social disorder and the decline in palm wine. (shrink)

The notion of semantic descent made familiar by Quine is extended to a movement from the first-floor level of language use to the level of objects that language typically describes; descent here is to a basement level. The idea of such a descent is combined with the idea of qualification to produce what is called the ‘Semantic Descent’ account of metaphor. According to this account, metaphor first requires semantic descent to a level of non-linguistic objects, and these objects then fulfill (...) the predicative function described as qualification. The account is presented in a relatively minimalist way, to show how it copes with the features of metaphor discussed in Chapter 1, as well as provide a clear view of the obvious objections that might be raised against it. The latter centrally includes the fear that the use of objects as qualifiers might be too indeterminate. This is countered with a discussion of a notion called ‘attunement’. (shrink)

'Que devrions-nous croire?' est la question centrale des débats philosophiques en éthique de la croyance, un champ complexe de philosophie contemporaine où se mêlent la normativité, les théories de la connaissance et la psychologie. Spécifiquement, ce livre aborde la question de si nous devrions croire certaines choses parce qu'elles sont vraies ou parce qu'elles sont utiles. Que croire lorsque les preuves s'opposent aux avantages pratiques d'entretenir une certaine croyance? Sous quelle condition devrions-nous croire quelque chose d'avantageux, bien que faux? Ces (...) questions ne peuvent faire l'économie d'autres débats portant sur notre autonomie et notre responsabilité quant à nos croyances. De par ces chemins sinueux vers les horizons normatifs de la croyance se dévoilent des questions sur les limites de l'activité philosophique."--Page 4 of cover. (shrink)

Uno de los motivos recurrentes del pensamiento contemporáneo, es la indagación sobre el concepto, la representación y la valoración de la comunidad como una dimensión de la experiencia, en particular en su incidencia política/impolítica. Pero "comunidad" se ha manifestado como un "semantema" elusivo, es decir, una familia de nociones y asociaciones significativas, que abren y complejizan más y más la búsqueda de un concepto preciso, hasta empujarnos hacia las típicas "vías negativas" para la caracterización o definición del mismo. A modo (...) de hipótesis, sin pretender con ello construir un esquema abarcador, sostendré que hay un núcleo estético en ese semantema, aludiendo con "estética" a la presencia, en el punto pivote de la constelación que delimita "lo comunitario", de términos como sonido/silencio, diferencia, doble, forma, identidad, imagen y semejanza. Se trata mayormente, como es evidente, de significaciones construidas sobre los planos auditivo y visual de lo sensorio. Como una especificación de dicha hipótesis, ensayaré la elaboración de una noción de comunidad a partir de la pregunta acerca de cuándo hay comunidad. La respuesta a articular, es que hay comunidad cuando hay imagen, esto es, corporización de una semejanza y de un sentido, capaces de conjurar tanto la amenaza de lo informe como la de la forma sin semejanza. El fundamento último de esta hipótesis, es que nuestro ser-en-común originario toma consistencia en el plano de lo sensible porque se vincula a la insuficiencia de toda representación para subordinarlo a un concepto, pues se presenta aquí, entre comunidad y concepto, la misma distancia infranqueable que hay entre la existencia y su teorización. One of the recurrent motifs of contemporary thought is the inquiry about the concept, representation and valuation of community as a dimension of experience, particularly in its political/impolitic influence. But "community" has proved to be an elusive semanteme, i.e., a family of notions and significant associations that make the search for a precise concept very complex, pushing us to the typical "negative ways" for its characterization or definition. As a hypothesis, and with no intention of building an all-encompassing frame, I will hold that there is an aesthetic nucleus to this semanteme, understanding "aesthetic" as the presence of terms such as sound/silence, difference, double, shape, identity, image and likeness, occurring at the very pivot point of the constellation that defines "the communitarian". It refers mostly to significances related to the hearing and seeing senses. Following this hypothesis, I will try to define a notion of community answering the question of when a community occurs. The answer to this being that there is a community when there is an image; that is, the embodiment of a likeness and a sense that can thwart the threat of what is shapeless or of a shape with no likeness. The ultimate foundation of this hypothesis is that our original being-in-common becomes consistent to the senses because of its inability to subordinate to a concept, as happens with any representation, being the unbridgeable distance between community and its concept the same there is between existence and its theorization.

DNA arrays have become the preferred method for large-scale expression measurement. Such data are needed in view of the large amounts of sequence data available: expression levels in a number of different tissues or situations provide a first step toward functional characterisation of new entities revealed by DNA sequencing. Although the basic principle of measurement is in all cases based on hybridisation of a mixed probe derived from tissue RNA to large sets of DNA fragments representing many genes, a number (...) of different forms of implementation of this principle are at hand. They are briefly described and compared, emphasizing the important issue of sensitivity and sample requirements and the accessibility of the methods to academic scientists. When these factors are taken into account, it appears that, contrary to a largely prevalent impression, the “best” approach is not necessarily always provided by the widely advertised glass microarrays or oligonucleotide chips.

From Pliny the Elder, who was his contemporary, to the present, the unhappy ending of the fourth Julio-Claudian emperor's life is often and uncritically retold. Thus Agrippina's poisoned mushrooms have become proverbial through the writings of Pliny, Juvenal and others. Historical evidence surrounding the circumstances of his death is, however, vague, contradictory, and open to alternative explanations. In the present note I shall argue for the simplest of these: that the emperor Claudius died after having ingested – either through criminal (...) intent, or by sheer accident – the most W poisonous of mushrooms, Amanita phalloides or Death Cap.

The central idea of the Semantic Descent account, namely qualification, can be used in a substantial way to clarify the debates about the relationship between thought and language, both within philosophy and psychology. Some remarks by Henle on how this notion has been just below the surface in writings about metaphor are highlighted. Brief suggestions are made about how it bears on debates about thought and language.

In the article, I set out to outline the state of play in contemporary philosophy of mind. Given the wide range of issues and contributions which now make up the subject, the article sketches only some of the main areas of investigation, and their interconnections without attempting to give a complete listing of the positions (and arguments for them) within these areas.

La recepción durante el siglo XX se preguntó si la filosofía nietzscheana era a-, im- o anti-política, es decir, si podía ser asimilada por la democracia, o si era antimoderna, elitista y reaccionaria. El italiano Roberto Esposito ha propuesto leerla como formando e informando el paradigma de la biopolítica. Se discuten cuatro lecturas de esa biopolítica: como formadora del paradigma de la inmunidad, como tanatopolítica, como liberal y neoliberal, y como biopolítica afirmativa. Twentieth-century readers wondered if Nietzschean philosophy was apolitical, (...) impolitic, or anti-political; that is, if it could be assimilated by democracy or if it was antimodern, elitist, and reactionary. The Italian philosopher Robert Esposito has proposed reading Nietzsche's philosophy as forming and informing the biopolitical paradigm. Four readings of these biopolitics are discussed: as part of the paradigm of immunity, as thanatopolitics, as liberal and neoliberal, and as affirmative biopolitics. (shrink)
