Testing for Periodicity and Trend in Long-Memory Processes
- 2003
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis presents methods of testing the periodicity and trend for the time series, which exhibit dependence over long periods of time. Many such processes can be modeled by a class of models called fractionally differenced processes. The first approach we consider to analyse such processes is by using the band periodogram, which divides the periodogram into different intervals or bands, matching the band-pass of the discrete wavelet transform (DWT). In other words, we have a number of high frequency bands and one low frequency band. We investigate the distribution of statistics based on these bands of the long memory processes at high frequency bands, and we show that these distributions are similar to those derived from white noise processes. The next approach for analysing long memory processes is by using the DWT. For long memory processes, the properties of the periodogram of the wavelet scales are similar to those of the band periodograms. We propose two tests for testing the periodicity in the case of long memory processes. The two tests are based on the two methods mentioned above. We develop the Fisher test in the case of simple periodicity, and the Siegel test when we have multiple periodicities. We use simulations to study properties of the tests; in particular we provide results on size and power of the tests. We also investigate the testing of trends in long memory processes. We suggest two test statistics. The first one is based on the quotient of the low frequency band in the periodogram and the high frequency bands. The second one is based on the ratio of low frequency band periodogram to the sum of other ordinates in the periodogram. We also use the DWT method for testing the trend. By the use of simulation we compare our tests with alternative tests. We further investigate the impact of periodicity and trend on different methods of estimating the long memory parameter. We provide a simulation study that shows how the periodicity and trend may affect such methods. We apply our methodology to several environmental time series.

De sobremesa 1887-1896 : José Asunción Silva:El poeta novelista
- 2004
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- José Asunción Silva is a Colombian poet most known for having renewed the metrics in Spanish poetry during the 19th century. José Asunción Silva's only novel, De sobremesa 1887-1896 [After dinner, 1887-1896] written in 1896 is a significant and representative modernist novel in the tradition of Latin-American modernismo.Silvas novel has been considered as a structureless, narratively disordered and chaotic text by many literary critics since its first publication in 1925. The text presents a great deal of fragmentation on the surface level: the story is presented by means of temporal discontinuity and multiple narrative voices and its thematic richness seems to be endless. The characters reveal multiple perspectives and a plurality of discourses.This dissertation determines and analyzes the formal and thematic aspects of the text that underlie its apparently disordered structure. The analysis focuses on the study of the referentiality of the text and some of its narrative components. It examines how the different fragments of the story, which are apparently neither logically nor thematically ordered on the surface level, are associated and integrated in the novel as a whole.Silva as a novelist makes use of some of the conventions of poetry and the techniques he applied to his poems. Contrast, association, assimilation and parallelisms are ways of creating new organizational forms of expressions in his prose work. The protagonist of De sobremesa, himself a poet, also plays the role of author, narrator, narratee and reader of his own prose work, his personal diary. This is a very particular feature in the context of Latin-American modernist novels written between 1882- 1902. The study analyzes the different roles of the character in the story to prove that the sense of unity is built by centring the text technically and thematically on the protagonist in its different roles. Silva makes the protagonist the point of convergence of the whole text.This dissertation suggests that there is an organized structure underlying the apparent disorder and incoherence of the text. The basis for Silvas text is diversity and the different where even the smallest parts prove to correspond with a bigger one. For a text of the 19th century, this is an innovative and experimental way of writing that seeks to create unity out of disorder and fragmentation.

Att leva med tiden : Samhälls- och kulturanalytiska perspektiv på ålder och åldrande
- 2011
-
Bok (övrigt vetenskapligt/konstnärligt)abstract
- Att leva med tiden handlar om vad ålder och åldrande kan betyda i olika sammanhang och hur betydelsen förändras över tid och rum. I boken diskuteras olika samhälls- och kulturvetenskapliga perspektiv på ålder och åldrande. Boken belyser vilka konsekvenser vetenskapliga sätt att se på åldrande kan få i analys av, och relation till, vardagsliv, vetenskaplig verksamhet och i det offentliga livet. Förutom historiska tillbakablickar presenteras också teorier om ålder, normalitet och identitet samt ålder ur ett intersektionellt perspektiv.
