[pt] Os métodos de amortecimento exponencial, apesar de originalmente proposto nos anos 60, continuam em pleno uso nos dias de hoje. Neste trabalho apresentamos um método novo para previsão de séries temporais com ou sem sazonalidade utilizando as teorias de amortecimento exponencial e análise harmônica. Assume-se que a série seja composta por uma tendência secular (constante, linear ou quadrática) e seus parâmetros são atualizados seqüencialmente pelo procedimento de amortecimento direto. Já a parte sazonal é tratada separadamente através da técnica de análise harmônica, conforme sugerida por Harrison, 1964. Dessa forma, o método proposto se apresenta como uma alternativa ao método de Souza & Epprecht, (1983) ; tendo como principal vantagem a rotina de estimação inicial dos parâmetros que no método de Souza & Epprecht produz estimadores tendenciosos em alguns casos. / [en] The method of exponential smoothing, although originally propesed during the 60´s, still continues in use up to today. In this thesis we present a new forecasting method for time series / with and/or without seasonality, applying the theory of exponential smoothing and harmonic analysis. It is assume that the series is composed of secular trend (constant, linear or quadratic) and a seasonal part. The trend parameters are sequentially using direct smoothing procedure. The seasonal part of the process is treated / separately through the technic of harmonica analysis according to Harrison´s suggestion, (1964). In this way, the proposed method can be viewed as an alternative to that of Souza & Epprecht, (1983), which has, as the most important advantage, the routine of initial estimation of the parameters, which in Souza & Epprecht method produces, in some cases, biased estimators.

Entr'actes and Sappho Fragments (1964) by English Composer Harrison Birtwistle represent extended notation, complex meters, and extended instrumental techniques. After World War II, the style and techniques of musical composition evolved considerably and musical trends began to continuously change. Conducting contemporary compositions requires new approaches in conducting methods. This paper examines a) introduce important elements of Birtwistle's compositions in the 1960, b) include an updated score of Entr'actes and Sappho Fragments (notated by the author), and c) provide a performance guide to the work.

In this thesis the main features of Harrison C. White’s general sociology are studied. Since the 1960s White has played a crucial role in the development of the social network approach. He is well known for both the fecundity of the analytical tools he has developed over the years and for the original contributions he has made to several sub­fields of the discipline. White has also developed an unconventional and highly individual approach to social reality that, as the end-result of a sustained synthesizing effort, has grown out of a long and persistent endeavor. Yet, more than a decade after its publication, this general theoretical approach still remains largely unexplored. The main argument of this study is that White’s approach represents one of the mast persistent, elaborated and systematic efforts to enrich the analytical rigorous of the social network approach by adding the substantive theoretical insights that have been elaborated mainly within the symbolic interactionist perspective and the tradition of phenomenological sociology. In this study, first the premises of White’s approach are examined. It is demonstrated how White uses social networks as an analytical tool in order to obtain causal explanations of social phenomena. It is also shown how White re- conceptualizes the notions of social relationship and embeddedness. Furthermore, it is also discussed how White, on the basis of these conceptual innovations, develops a novel image of modern social contexts. This study proceeds by presenting the set of new basic concepts that are derived from this image, seeking to locate these concepts within the larger and more familiar context of theoretical sociology. It is also demonstrated in this study that White’s particular image of modern social contexts leads him to pose new questions and to develop new modes of analysis to answer them. White’s view of modem societies radically alters the very nature and state of the question of social order as well as the premises of its answer. As White dismisses the conventional formulations of the problem of social order, he considers the issue to be a question of identifying the small enclaves of regularity within the social landscape that is dynamic, indeterminate and shifting. In more concrete terms, it becomes a question of identifying the limited, local and stable patterns or configurations of relationships that prove sustainable and thus observable, despite all the dynamics of embeddedness and connectivity. Finally, the basic theoretical features of White’s model of production markets are presented and discussed. Production markets is a topic to which White has devoted a great deal of interest. Ever since the mid-1970s he has produced a long series of work with the ambition of developing a sociological account of these markets. This account represents the most extensive application of White’s general sociology, where he fleshes out his abstract ideas and arguments and where one finds a concrete case of his account of the emergence of social structures and local orders out of network ties and flows. The main conclusion of this study is that, despite all its shortcomings, the general sociological perspective that White has developed is an important contribution. It provides sociology with a new foundation and shows the direction towards which the discipline should be moving. / <p>Diss. Stockholm : Stockholms universitet, 2003</p> / digitalisering@umu

Amphibians and aquatic invertebrates have complex life histories that link aquatic and terrestrial food webs. It has been suggested that amphibian reproduction is an important source of carbon to some aquatic systems. This process of energy flow may be shaped by shifts in habitat selection in response to predators. We hypothesized that predators decrease colonization and oviposition of prey, reducing active inputs. Thus predation risk is expected to shift the relative amounts of active and passive subsidies. We manipulated the presence of fish predators in aquatic mesocosms. Results suggest hylid treefrog eggs and hydrophilid beetles were less abundant in predator treatments. This difference in oviposition and colonization translated into small reductions in calories and ash free dry mass of active inputs. However, passive allochthonous inputs were more than double active amounts and variable, therefore relative amounts of active and passive inputs did not differ across the levels of predation risk.

Cathy Caruth's pioneering study of trauma and the posttraumatic forges a connection between the psychoanalytic theory of traumatic experience and the literary as such. Since trauma defies linguistic processing, she explains, the language used to describe it will always be figural. For this reason Caruth privileges imaginative literature, with its highly mediated nature, as a means of representing the otherwise "unclaimed" experience of trauma. Her influential reflections inform a crucial direction within trauma studies: the search for a narrative voice that articulates trauma effectively. But how should we think about trauma that is not a singular "event" but a chronic occurrence? Over the last twenty years trauma scholarship has explored how trauma outstrips discursive and representational resources, but has only begun to address the ways gender, race, and class must complicate our understanding of the posttraumatic. I argue that in order to frame an adequate approach to the posttraumatic, we must take account of the cultural, political, and social matrix of trauma. The feminist psychotherapist Maria Root has developed an idea that she calls "insidious trauma" to refer to the cumulative degradation directed toward individuals whose identities, such as gender, color, and class, differ from what is valued by those in power. Though not always blatant or violent, these effects threaten the basic well being of the person who suffers them. Root's conceptualization provides a useful framework for understanding certain long-term consequences of the institutionalized sexism, racism, and classism that systematically denigrate the self worth of the socially othered who are rendered voiceless. Where Caruth privileges literary representations of the traumatic, I explore how literature can also be a privileged site for the articulation of insidious trauma. My study addresses literary representations of father-daughter incest and the complex trauma associated with it, showing how--in very different ways--six works of modern American literature compel us to confront the traumatogenic nature of social oppression, especially that which is endemic to the structure of the heteropatriarchal family and American racism and classism. F. Scott Fitzgerald's Tender Is the Night ambivalently exposes the gendered politics of psychological trauma, particularly the conspiracy of silence perpetuated by a psychiatric culture that revictimizes the female victim of incest. Ralph Ellison's Invisible Man uses a story of paternal incest to work through the trauma of racism, challenging stereotypes of black masculinity even as it reinscribes patriarchal phallocentrism. Referencing Ellison's depiction of father-daughter incest, Toni Morrison's The Bluest Eye marks a watershed in the inscription of incest narratives as it is written mostly from the perspective of what I call a "could-be" victim of incest. Morrison includes the perspective of the father while foregrounding the experience of the daughter, exposing child abuse as an extensive social and political problem ultimately supported by imperialist ideals. Enabled by Morrison, Dorothy Allison's semiautobiographical Bastard Out of Carolina is narrated by a young "white trash" woman who shares her story of sexual violation in defiance of that culture's patriarchal structure. Conforming to certain class stereotypes of father-daughter incest, Bastard Out of Carolina escaped the hostile backlash provoked by Kathryn Harrison's memoir, The Kiss, whose critical reception suggests that, even while allowing some discussion of incest, mainstream culture continued to collude in its silencing within the context of the white middle-class. Finally, I revisit a particularly infamous literary narrative of father-daughter incest, Vladimir Nabokov's Lolita, but in terms of the feminist appropriation of Nabokov effected in Azar Nafisi's memoir, Reading Lolita in Tehran. Problematically downplaying the sexual abuse of Lolita, Nafisi appropriates Nabokov's work to bear witness to the patriarchal subjugation of women in her home country, the Islamic Republic of Iran.

The aim of this research is to examine the conceptual design issues concerned with integrating product capabilities that can only be generated at the micro- scale (through feature sizes generally of the order of 100nm to 100μm) directly into 3-dimensional products at the macro-scale. Such macro-scale products could accordingly contain internal devices that are too small to be seen or touched by unaided human designers, which begs the question as to how to enable designers to work with objects which are beyond direct human experience, and how can the necessary collective discussion take place within teams of designers, and between these teams and those responsible for product manufacture? This thesis examines and tests a concept that theoretical 2-dimensional diagrams of function may be transformed into 3-dimensional working structures using procedures allied to those used by graphic designers to create solid objects from 2-dimensional prototype geometries through, for example, extrusion or rotation. Applying such procedures to theoretical diagrams in order to transform them into scalable 3-dimensional devices is not yet in general use at the macro-scale, but with increasing recognition of the unique capabilities of the micro- scale the idea may grow in appeal to alleviate the difficulties of conceiving of functional structures that, when built, will be too small to experience directly. Furthermore this design method, through its basis upon a common currency of functional diagrams, may overcome many of the problems of describing and discussing the design and manufacture of normally intangible objects in 3 dimensions. Finally, it is shown through the example of a novel Red Blood Cell / Plasma Separation Device that the geometric transformation process can lead to the design of functional structures which would not readily be arrived at intuitively, and that may be effectively and efficiently integrated into host products.
