Nietzsche (1844-1900) nas Ciências da Linguagem. Perguntando-se sobre os pontos de contato entre as diversas teorias lingüísticas e o pensamento do filósofo, propõe-se a filiação da chamada hipótese Sapir-Whorf à filosofia de Nietzsche. Desse modo, procura-se compreender a constituição das teorias e dos métodos lingüísticos a partir do campo heterogêneo que caracteriza as Ciências da Linguagem. Apresenta-se com esse fim um panorama do problema da linguagem em Nietzsche e, em seguida, defendem-se os graus de consonância e dissonância entre os autores. Desse modo, argumenta-se que Nietzsche é uma condição de possibilidade para o pensamento de E. Sapir e B. Whorf. No jogo entre memória e esquecimento, é sempre lembrado o nome de W. von Humboldt enquanto "precursor" da hipótese. Percebe-se, entretanto, que no gesto epistemológico de "olhar para trás" em busca de bases, muitas vezes os autores, quando "voltam" desse gesto, o fazem já afetados por toda uma gama de outras idéias que modificaram a primeira, e é nesse sentido que se apresenta a filiação da hipótese a Nietzsche / Abstract: As from the point of view of History of Linguistic Ideas, the research investigates the filiations to the philosopher Friedrich Nietzsche (1844-1990) on the Language Sciences. By questioning the contact points between the various linguistic theories and the philosopher's thoughts, the filiation of the so-called Sapir-Whorf hypothesis to Nietzsche's philosophy is proposed. Thus, It seeks the understanding on the linguistic theories and methods constitution, as from the heterogeneous field that characterizes the Language Sciences. In order to do so, it presents an overview on the matter of language at Nietzsche and, thereafter, the levels of consonance and dissonance among the authors are endorsed. Hence, it is defended that Nietzsche represents a condition of possibility for E. Sapir and B. Whorf's reasoning. As in the play-off between memory and forgetfulness, the name of W. von Humboldt is always recalled as the "forerunner" of the hypothesis. It can be perceived, however, that on the epistemological act of "looking back" in search for ground, the authors often "return" from this gesture rather affected by a whole other range of ideas that have, thus, modified the previous ones, and it is in that sense that the hypothesis filiation to Nietzsche presents itself / Mestrado / Linguistica / Mestre em Linguística

The aim of this study is to examine how and why public libraries use Facebook. Internet has changed how people interact with one another in society. This is also true for how public libraries are active on social media just as their users are. This study is based on two questions; How do public libraries work with Facebook? Which purposes does work with Facebook serve? Employees at eight different public libraries were interviewed. Analysis was made by using the four-space model by Jochumsen et al. The findings show that the work with Facebook is organised differently between the libraries, which is either by a group or one or two individuals. Number of posts, how they are written and when they post, vary among the participating libraries as well. Consistency in posting leads to more followers and success on Facebook. The findings also show that the main reason for public libraries to use Facebook is to promote their activities and services. A majority of the libraries wants to interact with their users, but it is difficult to achieve. Contrary to what has been written before about this subject, a majority of the informants agreed that time is not an issue as the work is planned to include time for Facebook.

Selected Methodical Approaches to Regional Population Forecast: A case study in the South Bohemian Region Abstract The aim of this thesis is to introduce selected methodological approaches to population forecasts, focusing on the regional level and considering different lengths of time series. Specific procedures are applied to create a population forecast for the South Bohemian Region. In the theoretical part of this thesis, the stages of population forecasts processing are determined. The Cohort Component method with migration, which can be used to create population forecast, is characterized. Another part describes selected analytical models and functions for partial mortality, fertility and migration forecasts, including Indirect estimation of net migration. To extrapolate parameters, selected trending functions and the Box-Jenkins methodology are characterized in the part of the time series analysis. The analytical part of this thesis focuses on the creation of the South Bohemian Region forecast from short initial time series and long initial time series. From short initial time series, the partial forecast of mortality is analyzed by the Heligman-Pollard model, the partial forecast of fertility is analyzed by the Beta function and the partial forecast of migration is analyzed by 25%, 50% and 75%...

Dissertation thesis creates a complex and modern scheme for stochastic modeling of demographic processes, which is universally applicable to any population in the world. All calculations are described in detail on the data of the Czech Republic. Throughout the work the attention is drawn to the issues, that every analyst must necessarily take into account in order to obtain correct results. Data comes mostly from the Czech Statistical Office database. However, some data matrices had to be calculated for the purposes of the thesis. Particular demographic processes (mortality, fertility and migration) are modeled using selected modern approaches (ARIMA models, Lee-Carter method) and based on the constructed models these processes are forecasted to the future. Using partially projected results a comprehensive demographic projection of the population of the Czech Republic is created up to the year 2050. However, not on the basis of the current state and expert expectations of the future development, but based on sophistically projected demographic events, which are explained using the trends and main components of their previous development. This demographic projection is created in three scenarios (marked SC1, SC2 and SC3), which are made from selected optimal models, presented in particular sections of the work. One part of the thesis is also the backward retropolation of age-specific number of net migrants by sex in the Czech Republic since 1948. On its basis the analysis and prediction of the migration can be done. The thesis is a synthesis of the projections of demographic processess of mortality, fertility, and migration. Final results are confronted with three scenarios of population projections of the Czech Republic created by the Czech Statistical Office and five scenarios of population projections by Eurostat. The purely statistical approach of demographic forecasting in comparison with deterministic models and expert expectations has its positives and negatives. Therefore, the different results due to various methodological approaches are discussed and compared in the conclusion of the thesis.

The 1st and 2nd order Lee–Carter methods were compared with the Hyndman–Ullah method in regards to goodness of fit and forecasting ability of mortality rates. Swedish population data was used from the Human Mortality Database. The robust estimation property of the Hyndman–Ullah method was also tested with inclusion of the Spanish flu and a hypothetical scenario of the COVID-19 pandemic. After having presented the three methods and making several comparisons between the methods, it is concluded that the Hyndman–Ullah method is overall superior among the three methods with the implementation of the chosen dataset. Its robust estimation of mortality shocks could also be confirmed.

Denna kandidatuppsats består av en egen översättning från engelska till svenska av första kapitlet från författaren Jesse Lee Petersons verk From Rage to Responsibility: Black Conservative Jesse Lee Peterson and America Today. Uppsatsen består dessutom av en källtextanalys samt översättningskommentarer som exemplifierar och diskuterar översättarens tillvägagångssätt i att åstadkomma en översättning som uppnår dess syfte. Syftet har primärt varit att överföra källtextinnehållet till måltexten och den djupare förståelse som förmedlas relaterat till ilska, självinsikt, förlåtelse och ansvar, på ett sätt som samtidigt bevarar författarstilen i möjligaste mån. Detta inkluderar en överföring av författarens lättsamma stil och användning av verbala och talspråkliga drag, idiom och kulturreferenser, samt en anpassning av syntax. För att åstadkomma detta har framförallt översättningsteorier och begrepp från Benjamin Walter och Theo Hermans tillämpats under översättningsprocessen och i översättningskommentarerna. / This essay is based on my own translation of the first chapter of author Jesse Lee Peterson’s work From Rage to Responsibility: Black Conservative Jesse Lee Peterson and America Today, in the language pair English to Swedish. The essay also includes a source text analysis, as well as a commentary on my own translation, where the translator’s approach in achieving a target text that accomplishes its aim is discussed and exemplified. The aim has primarily been to transfer the source text’s ideational core to the target text and the deeper understanding that is being conveyed, regarding rage, insight, forgiveness and responsibility, in an equivalent manner which stays faithful to the style of the author, to the extent that is considered possible. This includes the transference of the author’s cultural references, easy going and simple stylistic approach, along with the informal and colloquial language use, as well as a syntactic target language adaptation. To achieve this, the ideas and terms from the translation theorists Benjamin Walter and Theo Hermans have been applied during the translation process and in the commentary.

Studier av livslängder och dödssannolikheter är avgörande för livförsäkring. Betalningar gällande livförsäkringar är helt beroende av om en individ lever eller ej, eller befinner sig i olika hälsotillstånd. För att kunna prissätta premier korrekt och avsätta reserver är det därför av stort intresse att modellera livslängden på ett så korrekt sätt som möjligt. Försäkringsbranschen använder idag historiskt beprövade och välfungerande modeller som går så långt bak i tiden som 200 år. Det finns modeller ännu längre bak i tiden, men de modeller som används idag är främst Gompertz (1826), Makeham (1860) och Lee-Carter (1992). Även om dessa modeller presterar bra är det alltid nödvändigt att undersöka om det kan finnas alternativa modeller som modellerar dödligheten bättre. I detta examensarbete tillämpas affina korträntemodeller för modellering av dödlighetsintensiteten som ligger till grund för flertalet intressanta aktuariella storheter. Då dessa modeller introducerar stokastisk dödlighet kan osäkerheten och beroendet över tid därmed beskrivas. De korträntemodeller som undersöks i arbetet och som är vanligt förekommande inom den finansiella teorin; är Ornstein-Uhlenbeck, Feller och Hull-White. Dessa modeller jämförs sedan mot varandra vad gäller modellerad dödlighetsintensitet samt förväntad återstående livslängd och ettårig dödssannolikhet. En aspekt av stokastisk dödlighetsmodellering som ej återfinns i befintlig litteratur men som undersöks i detta examensarbete är modellering av dödlighet över tid då detta är en av de mest väsentliga aspekterna inom det livförsäkringsmatematiska arbetet. Till sist i valideringssyfte utvärderas samtliga korträntemodeller genom back-testing. Den andra huvudsakliga delen av arbetet består i att generera resultat för samma storheter som ovan baserat på DUS-metoden för att på så sätt jämföra en kommersiell metod mot en mer teoretisk mindre beprövad sådan. Resultaten visar på en stor potential hos flera av korträntemodellerna kontra DUS både vad gäller modellering över åldrar och kalenderår. Däremot är inte resultaten helt felfria för enstaka kalenderår där stora spikar uppstår på grund av parametermässig felanpassning. Modelleringen av korträntemodellerna över tid var över förväntan då modellerna inte är konstruerade för att fånga avtagande trender. Detta är något som kan betraktas som en stor flexibilitet hos korträntemodellerna då de står sig väl mot Lee-Cartermodellen som används i DUS, både vad gäller ålders- och tidsmodellering av dödlighet. / Studies of life expectancy and death probabilities are crucial for life insurance. Payments for life insurance are completely dependent on whether an individual is alive or not, or is in various health conditions. In order to be able to price premiums correctly and set aside reserves, it is therefore of great importance to model life expectancy in the most accurate way possible. The insurance industry today uses historically proven well-functioning models that go as far back in time as 200 years. There are models even further back in time, but the models used today are mainly Gompertz (1826), Makeham (1860) and Lee-Carter (1992). Although these models perform well, it is always necessary to investigate whether there may be alternative models that model mortality better. In this thesis, affine short-term interest rate models are applied for modeling the force of mortality that forms the basis for most interesting actuarial variables. As these models introduce stochastic mortality, the uncertainty and dependence over time can thus be described. The three short-term interest rate models examined in this project, which are common in financial theory; are Ornstein-Uhlenbeck, Feller and Hull-White. These models are then compared against each other in terms of the modeled force of mortality as well as the expected remaining life expectancy and the one-year probability of death. One aspect of stochastic mortality modeling that is not found in the existing literature but which is examined in this thesis is the modeling of mortality over time as this is one of the most important aspects in the life insurance mathematical industry. Finally, for validation purposes, all short-term interest rate models are evaluated using back-testing. The second main part of the work consists of generating results for the same quantities as above based on the DUS method in order to compare a commercial method with more theoretical and less approved ones. The results show a great potential in several of the short-term interest rate models versus DUS both in terms of modeling over ages and calendar years. However, the results are not completely impeccable for individual calendar years where large spikes occur due to inaccurate parameter calibration. The satisfactory modeling of the short-term interest rate models over time was above the expectations as the models are not designed to capture decreasing trends. This is something that can be considered a great flexibility of the short-term interest rate models as they are more or less as accurate as the Lee-Carter model used in DUS, both in terms of age and time modeling of mortality.

Korean composer Young Jo Lee (b.1943) is considered a precursor of Korean fusion music. In his works, he interlaces elements of traditional Korean music with compositional styles and performances techniques from western musical traditions. This dissertation provides an analysis of Lee's Dodri for Cello and Janggo (1995), one of his most representative works of fusion music. As indicated by the title Dodri (which in Korean means a "movement back and forth"), Lee intended to showcase a friendly interplay of the janggo and the cello, with each instrument playing a leading role that helps bring out the essence of traditional Korean traditional music. In this piece, Lee writes a number of melodies and uses traditional Korean performance techniques for the cello intended to imitate the sound and sentiments of traditional Korean instruments, all while preserving its inherent nature. This kind of fusion, where different musical elements are merged with each other but remain separate enough to maintain their own uniqueness, is significant to Lee's philosophy. This dissertation also describes Lee's efforts to preserve the integrity of traditional Korean music within fusion music and lend new insights regarding traditional Korean musical practice to musicologists, composers, and audiences. Furthermore, this study is intended to serve as a performer's guide for professional cellists new to Lee's music so they may approach Dodri with a greater understanding of the composer's original intentions when first learning the work.

Essay 1 (with Juha Alho and Edward Palmer):  All around the world, public pension schemes are moving in the direction of non-financial (NDC) and financial defined contribution (DC) schemes.  Both rely on accurate projections of life expectancy in the creation of annuities. Accurate projections are critical for system stability, individual utility and inter-generational welfare. This paper suggests a path-breaking innovation that changes the perspective from the Lee-carter (LC) family of trend models which assume a constant rate of change in mortality over time. Our approach is to project the cohort life expectancy on basis of the specific cohort rate of change in mortality. This relaxes the strong trend assumption underlying the LC model, which is the reason why LC model does not work well in the phase of accelerating or decelerating mortality. We use unisex mortality data for $8$ countries to test the performance of our approach both ex-post and ex-ante. The ex-post experiment shows that our approach generally performs better when the rate of change in mortality is accelerating and performs as well as LC model when the rate of change is time-invariant. The ex-ante experiment, on the other hand, shows that our model almost always delivers higher projection of remaining life expectancy than the LC model for the more recent cohorts, which is consistent with the ex-post experimental results. / Essay 2:  Due to the systematic underestimation of cohort life expectancy, NDC pension schemes face a financial risk that can leads to inter-generational unfairness, given the current practice. This paper proposes an alternative method of computing annuity to address this problem. The proposal is to adjust the annuity based on re-estimations of the remaining life expectancy at intervals after retirement, but only up to a ceiling age. The scheme is assessed using 208 cohort annuity pools from eight sample countries. This experiment shows that the proposed scheme succeeds in reducing the inter-generational unfairness for 60-80% of the cohort annuity pools, compared to current practice of fixing the annuity at age 65. Because the adjustment is borne by the relatively large group of younger persons, the per capita change in utility is rather small assuming risk neutrality. / Essay 3:  This paper studies how the incentive to retire in a DC (NDC) scheme is influenced by engaging private information on life expectancy. This is an important question since the decisions made under the two scenarios, optimizing using the private life expectancy or the cohort average made available by the pension provider, create different welfare and financial outcomes. The analytical framework is a standard life-cycle model, accounting for monetary gain from work and non-monetary gain from leisure. The unique feature here is that the individual life expectancy is an explicit driver of disutility of work. The theoretical result is that prevailing private information of a longer-than-average life expectancy can lead to both advancing and delaying retirement, depending on other factors determining utility. The numerical example using Swedish data proves the theoretical results and suggests a rather small average impact on the choice of retirement by engaging private information of life expectancy. / Essay 4:   Pensions in the increasingly popular Notional Defined Contribution (NDC) Pay-as-You-Go Schemes are granted based on cohort-specific life expectancy, regardless socioeconomic differences. This risks perverse intra-generational and unintended inter-generational transfers. This paper introduces an alternative with separate annuity pools for different socioeconomic classes. Using unique Swedish data and the Swedish NDC pension system as an example, the analysis shows a significant gap in life expectancy between socioeconomic classes defined by occupation. In the Swedish context, this implies a perverse transfer of 5% of the pension capital from the manual workers to the non-manual workers, which can be abolished by using the group plan. In addition, the group plan also lessens the risk of inter-generational transfers resulting from the gap in life expectancy.
