就目前所知，這是第一篇應用人工類神經網路在股票風格投資方面的研究。類神經網路在樣本內與樣本外的分類正確率皆優於區別分析，而且類神經網路在樣本內的訓練範例中達成了百分之百的分類正確率。此外，我們也解決了傳統方法無法展示股票風格動態的問題。 檢視各種風格投資策略在台灣股票市場的績效表現之後，我們以神經網路為基礎，提出一個簡單而容易實行的投資策略。由這個策略的表現可以說明，即使在考慮了風險因素之後，積極的風格投資策略的確可以增加投資組合的績效表現。 / This is the first study of applying artificial neural networks (ANN) to classify and identify the equity styles. Regarding the accuracy, ANN outperforms discriminant analysis (DA) in all pure samples from 1987 to 1997. The ANN also commits the 100% classification accuracy for the in-sample training samples. In addition, the problem that traditional approach couldn't show equity style dynamics was solved with ANN and DA. The performances of style investing strategies were examined in Taiwan stock market. The proposed strategy is easily implemented by constructing portfolios based on the return, which neural networks forecasted. There is good evidence to show this simple strategy could enhance profit on the return and risk adjusted basis. This gives one evidence to illustrate that active style investing would add value.

Nur langsam scheinen jene Schockwellen abzuebben, die ausgelöst durch die Ergebnisse der PISA-Erhebungen seit mehr als einem Jahrzehnt die Bildungsrepublik Deutschland durchqueren und weite Teile der Gesellschaft in den Zustand regelrechter Bildungspanik versetzten. An der Schwelle zum 21. Jahrhundert belegte eine Reihe von Studien für das wiedervereinte Deutschland eine im OECD-Vergleich besonders ausgeprägte Abhängigkeit des Bildungserfolges von der sozialen Herkunft. Als eine Konsequenz ist der Zugang zu tertiärer Bildung bis dato deutlich durch soziale Ungleichheit gekennzeichnet. Vor diesem Hintergrund leistet die vorliegende Dissertationsschrift einen wesentlichen Beitrag zur ursächlichen Erklärung von Mustern sozialer Selektivität, die an den Gelenkstellen zwischen sekundären und postsekundären Bildungsangeboten sichtbar werden. Auf innovative Weise verbindet die Arbeit ein zeitgemäßes handlungstheoretisches Modell mit einer komplexen Lebensstilanalyse. Die Analyse stützt sich auf Erhebungsdaten, die zwischen Januar und April 2010 an mehr als 30 weiterführenden Schulen des Bundeslandes Brandenburg erhoben wurden. Im Mittelpunkt des Forschungsinteresses steht einerseits die Identifikation von sozial-kognitiven Determinanten, die das Niveau und die Richtung postsekundärer Bildungsaspirationen maßgeblich vorstrukturieren sowie andererseits deren Verortung im Kontext jugendlicher Lebensstile. Das komplexe Analysedesign erweist sich als empirisch fruchtbar: So erbringt die Arbeit den empirischen Nachweis, dass die spezifischen Konfigurationen der bestätigten psychosozialen Prädiktoren nicht nur statistisch bedeutsam zwischen jugendlichen Stilmustern variieren, sondern sich diesbezüglich erfolgreiche von weniger erfolgreichen Typen unterscheiden lassen. / The results of the PISA-inquiry sent shock waves through society, influencing education policy and causing large portions of society angst over education; these effects have subsided slowly over the past decade. A series of studies concerning a reunited Germany conducted at the beginning of the 21st century found a particularly strong correlation between educational success and social demographics as compared to the OECD, the consequence of this pattern being an inequality between social demographics in terms of access to tertiary education. Against this background, the presented dissertation thesis contributes to a causal explanation of patterns of social selectivity which become visible at the transition between secondary and post-secondary education. This thesis combines a contemporary action-theoretical approach with a complex life-style analysis in an innovative way. The analysis is based on survey data collected at more than 30 continuative/ post-secondary schools in Brandenburg (Germany) between January and April of 2010. Focus of the research is the identification of social-cognitive factors which significantly structure standard and direction of post-secondary aspirations as well as their localization in context of adolescent life-styles. The complex design of the analysis proves to be empirical fertile: Therefore, this thesis provides the empirical verification that the specific configurations of the affirmed psycho-social predicators do not only vary statistically important between adolescent style-patterns but provide the basis to differentiate between successful and less successful types.

Marlos Nobre composed four Ciclos Nordestinos for piano but the fourth has not been approached for there is no revised revision up-to-date. The analysis of the Ciclos Nordestinos focused on the five parameters proposed by Jan LaRue: Sound, Harmony, Melody, Rhythm and Growth. It is also included observations about technical aspects and performance suggestions. The analyses show the existence of a great difference of level of performance between the First one and the Third Cycles; the asymmetry in the three Cycles compared between themselves in relation to the indication of speed and character; the existing quotation removed of the folk/popular origin; and the concern of the composer in placing some possibilities of study for a pupil of the piano, however, most important of them is the dissociation between left hand and right hand. / O presente trabalho constitui-se na análise dos Ciclos Nordestinos para piano de Marlos Nobre, através de duas fontes distintas de referencial teórico: o conhecimento teórico e prático de elementos que compõem a música folclórico/popular brasileira, especificamente a nordestina, e a análise estilística proposta por Jan LaRue. Marlos Nobre compôs quatro Ciclos Nordestinos para piano, porém, foram analisados apenas os três primeiros, por ainda não existir revisão e edição do 4º Ciclo Nordestino. A análise dos Ciclos enfoca cinco parâmetros, conforme o esquema analítico de LaRue: Som, Harmonia, Melodia, Ritmo e Crescimento. Também foram incluídas observações sobre aspectos técnico-pianísticos, além de sugestões interpretativas. Como principais conclusões podem-se notar a existência de uma grande diferença de nível de execução entre o Primeiro e o Terceiro Ciclos; a assimetria nos três Ciclos comparados entre si em relação à indicação de andamentos e caráter; a existência de citações literais retiradas do cancioneiro popular e uma preocupação do compositor em colocar várias possibilidades de estudo para um aluno de piano, a mais importante delas é a dissociação entre mão esquerda e mão direita.

[pt] Esta dissertação se propôs a investigar e interpretar o estilo de investimento de fundos de investimento brasileiros – fundos cambiais e de ações com administração ativa, no período de janeiro de 2004 a agosto de 2008, com o objetivo central de verificar se, de fato, estes fundos perseguem o estilo de investimento prometido aos seus clientes. Nesse sentido, foi empregada a metodologia de análise dinâmica de estilo baseada no retorno, utilizando o filtro de Kalman restrito reduzido com inicialização exata aplicado sobre modelos em espaço de estado. Para tanto, novos índices foram confeccionados a fim de cobrir a eventual carência de índices que pudessem apropriadamente representar as classes de ativos do mercado financeiro a que os fundos estão expostos. As principais conclusões obtidas foram: (1) mesmo em meio a um cenário adverso que marcou parte do período analisado, os fundos cambais mantiveram as estratégias de investimento anunciadas ao público, demonstrando transparência em suas ações; e (2) os fundos de ações estiveram, de fato, predominantemente expostos ao mercado bursátil, mas também alocaram parte considerável de seus recursos em títulos públicos federais de longo prazo indexados a índices de inflação. / [en] This dissertation aims to investigate and interpret the investment style of Brazilian investment funds - exchange funds and stock funds with active management, in the period ranging from January 2004 to August 2008, with the central objective of verifying if, in fact, these funds pursue the investment style promised to their customers. Accordingly, we used the methodology of returnbased dynamic style analysis, using the reduced restricted Kalman filtering with exact initialization applied to state space models. For this purpose, new indexes were created with the intention of covering the eventual lack of indexes that could appropriately represent the asset classes of financial market. The main conclusions were: (1) even in the midst of an adverse scenario that marked part of the analyzed period, the exchange funds kept the investment strategies announced to the public, demonstrating transparency in their actions; and (2) stock funds were indeed predominantly exposed to the stock market, but also allocated considerable part of their resources on federal public long-term bonds indexed by inflation indexes.

Human motion analysis is one of the major problems in computer vision research. It deals with the study of the motion of human body in video data from different aspects, ranging from the tracking of body parts and reconstruction of 3D human body configuration, to higher level of interpretation of human action and activities in image sequences. When human motion is observed through video camera, it is perspectively distorted and may appear totally different from different viewpoints. Therefore it is highly challenging to establish correct relationships between human motions across video sequences with different camera settings. In this work, we investigate the geometric invariance in the motion of human body, which is critical to accurately understand human motion in video data regardless of variations in camera parameters and viewpoints. In human action analysis, the representation of human action is a very important issue, and it usually determines the nature of the solutions, including their limits in resolving the problem. Unlike existing research that study human motion as a whole 2D/3D object or a sequence of postures, we study human motion as a sequence of body pose transitions. We also decompose a human body pose further into a number of body point triplets, and break down a pose transition into the transition of a set of body point triplets. In this way the study of complex non-rigid motion of human body is reduced to that of the motion of rigid body point triplets, i.e. a collection of planes in motion. As a result, projective geometry and linear algebra can be applied to explore the geometric invariance in human motion. Based on this formulation, we have discovered the fundamental ratio invariant and the eigenvalue equality invariant in human motion. We also propose solutions based on these geometric invariants to the problems of view-invariant recognition of human postures and actions, as well as analysis of human motion styles. These invariants and their applicability have been validated by experimental results supporting that their effectiveness in understanding human motion with various camera parameters and viewpoints.

In this study, I took the quantitative research approach of film statistical stylistic analysis to examine the editing pattern evolution of 130 Hollywood movie trailers over the past 60 years from 1951 to 2015; the prior studies on the overall evolution of the Hollywood movies’ editing pattern are compared and discussed. The results suggest that although the movie trailers are much shorter than the whole movies, the average shot lengths of the trailers still display a declining trend over the past 60 years, and the variations in the shot lengths are also decreasing. Second, the motions within each framedo not change significantly over the years, while the correlation coefficients between the shot lengths and the motions within the shots are moving toward a more negative correlation relationship over time, suggesting that the trailers are subject to an editing evolution trend that the shorter the shot is, the more motions there are within it, and this also aligns with the overall movies’ editing pattern evolution trend. Last, the luminance of the trailers remains almost the same over time, which does not align with the overall movies’ editing pattern evolution of becoming darker and darker over decades. Together these findings suggest that the movie trailers’ editing rhythm evolution in general aligns with that of overall movies over time while the visual editing pattern evolution of color luminance does not. The study results will improve our understanding on how the Hollywood movie trailers’ editing pattern and style have evolved over time and pave the way for future advertising studies and cognitive psychology studies on the audience’s attention, immersion and emotional response to various editing patterns of movie trailers. / Media Studies & Production

L’archéologie paléolithique peine à esquisser la complexité des sociétés humaines. Le principal obstacle qui demeure concerne les réalités sociales, culturelles, et finalement humaines, que sous-tendent les vestiges qu’elle exhume. La méthode élaborée dans le cadre de cette thèse a pour ambition de compléter la réflexion menée sur la définition des « cultures » et des « territoires » préhistoriques, en les abordant du point de vue des unités sociales et de leurs dynamiques. Cette étude s’est également efforcée de réviser l’analyse des styles et le rôle des objets ornés dans les dynamiques sociales des chasseurs-cueilleurs préhistoriques. À cette fin, la réflexion menée repose sur un postulat fondamental : le fait anthropologique que la culture matérielle est partie prenante des processus d’identification et d’interactions sociales, à la fois participant et étant influencée par ces comportements. Le style des objets (manière de faire) et leur répartition dépendent donc des interactions entre individus et groupes, en lien étroit avec leur environnement naturel et social. Il est donc fait appel à des récurrences anthropologiques qui fournissent des clés de lecture pour la distribution et l’évolution des styles de la culture matérielle au regard des contextes et dynamiques sociales qui en sont responsables. Cette méthode est testée sur une approche synchronique et diachronique des objets ornés du Magdalénien, mis au jour dans le centre-ouest de la France (environ 18 000 à 12 000 ans BP). Cette étude est complétée d’une discussion transdisciplinaire des hypothèses interprétatives ainsi formulées. / Palaeolithic archaeology struggles to reach human societies complexity. The main issue relates to social, cultural, and overall human realities underlying the excavated remains. The methodology herein developed aims at clarifying the characterization of prehistoric “cultures” and “territories” by approaching them through social units and their dynamics. Moreover, the present study endeavours to revise style analysis and the part played by ornamented goods within prehistoric hunter-gatherers’ social interactions. The keystone to this issue relies on the anthropological fact that material culture is “an active constitutive dimension of social practice in that it both structures human agency and is a product of that agency” (Jones, 1997). Consequently, its styles depend on interaction modalities and evolution, in relation to their natural and social environment (mainly resources and human demography). Therefore, this research invokes social anthropology’s recurrences which provide a fundamental framework to interpret distribution and changes of styles depending on the context and social dynamics influences. The present methodology is experimented on a synchronic and diachronic approach of Magdalenian portable art from western central France (ca. 18 000 to 12 000 years BP). This study is completed by a transdisciplinary discussion of the herein devised interpretative hypotheses.

With the evolution of chess, there has been developed thousands of chess openings at present. This makes it difficult and time-consuming for chess players to find and learn the openings suitable for them. For helping players to learn chess in the opening, we provide Opening Recommendation System (OPRS), which considers chess players’ experiences and recommends chess openings that could be understandable and favorite for the players. For personalized recommendation, OPRS analyzes the playing style, translates chess rating, extracts the playing patterns, and then performs hybrid recommendation based on the features obtained. In the evaluation, the performance of the playing style analysis are demonstrated by comparing with the styles judged by chess experts for world chess championships. For OPRS, the evaluations are according to the openings the players use in the chess tournaments in the next years. The experiments show that OPRS achieves good accuracies of the playing style analysis and outperforms the competitive methods for chess opening recommendation.
