Full textTo try to answer this interrogation, the dissertation is placed within the general framework of the cognitive psychometry. The general assumption is that the task to be realized in the MFFT, which imposes a "spontaneous" speed-accuracy trade-off, involves general processes of control and regulation whose theoretical knowledge and individual evaluation in a possible diagnostic aim are interesting aspects. These processes implying, according to the literature, the executive functions and processes, we adopted this executive perspective through tests of inhibition and flexibility completed by an approach in terms of capacities (of working memory) and of speed of information processing. Four studies, undertaken with a total of 299 10-year-old children, indicate that the speed-accuracy trade-off concerns general adaptive processes, and clarify the implication of the working memory and, with a less degree, of the flexibility in this trade-off

Full textThe main aim of the study was to investigate the multiple-acceleration task construct from vertical jumps biomechanics parameters. Nineteen female basketball players from Brazilian national team performed the multiple-acceleration test (T test), countermovement jump (VJ) and countermovement jump preceded by run (VJr). The VJ biomechanics parameters observed were: concentric phase duration (CPD), propulsion peak force (PPF), time to reach propulsion peak force (TPPF), rate of force development (RFD) and impulse (I); for VJr the parameters were mean velocity (MV), movement total duration (MTD), passive peak force (PaPF), time to reach passive peak force (TPaPF), propulsion peak force (PPF), time to reach propulsion peak force (TPpPF), load rate (LR) and rate of force development (RFD). Data were first analyzed by principal component analysis. The results showed that 61.3% of VJ variance could be explained by time factor (CPD, TPPF and PPF), and 20.7% by kinetic factor (I and RFD). To VJr, 58.7% of total variance could be explained by time factor (MTD, TPaPF, TPpPF, LR, RFD) and 15.4% by kinetic factor (PPF and PaPF) and 12.8% by velocity factor (MV). Furthermore, significant correlations were found between T test with CPD, MV and PPF (0.55, -0.54 and -0.49, respectively), revealing a T test construct related to the ability of generating high level of force in concentric phase, diminishing time of concentric phase, and to reach the change direction point with greatest possible speed.

Full textAs soon as it was designed, the IQ test was marred by a methodological and ideological bias. However this did not prevent it being widely spread. Today the tendency is to consider “the exceptionally gifted” as founding a new psychopathological category. Is cleverness a new illness? Such is the question at stake. The new era of psychology and psychiatry has designed a clinical approach of the exceptionally gifted child which comes down to legitimating the arbitrariness of the original taxonomy. After shedding light on the historical and logical foundations of the test, the present study means to explain why the general public crave for more and more measurements and numbers, always more of this “generalized evaluation” of which IQ test is the paradigm. A radical transformation of the Master’s Discourse (Lacan) explains the fascinating power of the test. In the era of the inconsistency of the Other, characterized by the faltering of the semblants, what becomes of the subject’s identification? Following Lacan’s logic of the nominating process, master signifiers - such as “exceptionally gifted” - nowadays mass-produced, are positioned as the truth. Granted some form of divine power they are as the “iron mask” of the plus-de-jouir (Lacan). Sometimes, the inventive subject adopts these signifiers for his own. More often they weigh heavy. Listening to the tested exceptionally gifted allows us to understand how on a large scale their segregation is organized, on the basis of their falling under master signifiers which identify them as different, throwing a new light on some aspects of the contemporary suffering which Freud considered as relevant to the discontents of Civilization

Long-term ecosystem changes, such as regime shifts, have occurred in several marine ecosystems worldwide. Multivariate statistical methods have been used to detect such changes, but they have to date not been applied to the southern Benguela ecosystem. A weakness of many of the methods is that they require long time series data and do not provide robust results at the end of time series. A new method known as the sequential t-test algorithm for analysing regime shifts (STARS) is applied to a set of biological state variables and environmental and anthropogenic forcing variables in the southern Benguela.

Full textThe purpose of this study was to analyze which part of the pre-season trainings two cycles that affected strength and power in lower extremities, acceleration, agility and anaerobic endurance by compiling these abilities of a female elite soccer player team, and then evaluate whether the pre-season training improved these abilities. Tests that could prove important and crucial physical qualities in elite soccer players were selected and then performed on three occasions; before, during and after the pre-seasontraining. The selected tests were; squat, vertical jump, 15 m sprint, T-test and YO-YO Intermittent Recovery Test (YO-YO IR). The study included 24 female elite soccer playersfrom all playing positions. A significant improvement in strength, agility and anaerobic endurance were measured in the second test round. In the other tests there were no difference observed. The first cycle of the pre-season training partly developed the players in the right direction, which the significant improvement in strength revealed. The significant improvement in the agility and anaerobic endurance occurred a little too early, it would have been more beneficial after the second cycle. This means that other important qualities might have been neglected.

Microarrays technologies are used to measure the expression levels of a large amount of genes or fragments of genes simultaneously in diferent situations. This technology is useful to determine genes that are responsible for genetic diseases. A common statistical methodology used to determine whether a gene g has evidences to diferent expression levels is the t-test which requires the assumption of normality for the data (Saraiva, 2006; Baldi & Long, 2001). However this assumption sometimes does not agree with the nature of the analyzed data. In this work we use the skew-normal distribution described formally by Azzalini (1985), which has the normal distribution as a particular case, in order to relax the assumption of normality. Considering a frequentist approach we made a simulation study to detect diferences between the gene expression levels in situations of control and treatment through the t-test. Another simulation was made to examine the power of the t-test when we assume an asymmetrical model for the data. Also we used the likelihood ratio test to verify the adequability of an asymmetrical model for the data.
Os microarrays são ferramentas utilizadas para medir os níveis de expressão de uma grande quantidade de genes ou fragmentos de genes simultaneamente em situações variadas. Com esta ferramenta é possível determinar possíveis genes causadores de doenças de origem genética. Uma abordagem estatística comumente utilizada para determinar se um gene g apresenta evidências para níveis de expressão diferentes consiste no teste t, que exige a suposição de normalidade aos dados (Saraiva, 2006; Baldi & Long, 2001). No entanto, esta suposição pode não condizer com a natureza dos dados analisados. Neste trabalho, será utilizada a distribuição normal assimétrica descrita formalmente por Azzalini (1985), que tem a distribuição normal como caso particular, com o intuito de flexibilizar a suposição de normalidade. Considerando a abordagem clássica, é realizado um estudo de simulação para detectar diferenças entre os níveis de expressão gênica em situações de controle e tratamento através do teste t, também é considerado um estudo de simulação para analisar o poder do teste t quando é assumido um modelo assimétrico para o conjunto de dados. Também é realizado o teste da razão de verossimilhança, para verificar se o ajuste de um modelo assimétrico aos dados é adequado.
Janstad, Tobias. "Case study of a contract system : considering pulp prices from 1996-2006." Thesis, Växjö University, School of Mathematics and Systems Engineering, 2007. http://urn.kb.se/resolve?urn=urn:nbn:se:vxu:diva-1684.
Full textSödra Cell sells 1 900 000 ton pulp every year. Of this 490 000 tonne is sold with a contract system based on a pricing index called PIX NBSK. This index was started in 1996 and reflects the price of pulp from conferious forest. We study the NBSK PIX value of softwood from October 1996 to December 2006.
People working in this branch known that there is strong periodicity in the prices. We use predictive analysis to see if clients can benefit from the periodicity and use the options in the contract system Södra offers today. We conclude that a drawback for the current contract system is that there are too many contracts in proportion to the duration time that is one year for all contracts. Using a time series model called ARMA we make successfull predictions the price difference between two contracts. Based on this prediction we change between these contracts, reducing the price with 0.81% in mean during 1997-2006. Due to the total turnover, if all clients would used such predictions during 1997-2006 Södra's income would have been reduced with 2.77 million USD a year in mean.
The prices used before PIX are called list prices. The list prices seem to behave like the PIX index. Supposing that the same contract system we see in PIX today was used 1975-2006 with the list price as the base index I made a prediction of the list prices from 1986-2006. Thanks to my predictions, if I had been a client during this period and under mentioned considerations I would have been buying pulp to a price reduced with 0.57%.
If clients had known the PIX between 1996-2006 in say 1995 Södra's contract system based on PIX would give them a price reduction that were 1.5% in mean during 1996-2006. Price reduction is not possible all years, but when it occurs it can be as big as 3% of the price. Suppose the clients always choose the contract with the lowest price and thereby get a reduced price over time. Then with 95% probability over a long period the price reduction is somewhere in between 0.4-2.7%.
To strangle this price reduction possibility for the clients there are two ways to go: either reduce the number of contracts or extend the duration time of the contracts.
To find a suitable duration time, we do spectral density estimation to get indications of which periods that are most important. From this we see that PIX index has a period of five years, wavelet approximated PIX index has 3.4 years and the list prices has a period of 5.6 years. This indicates that current duration time one year is too short. Therefore if it wouldn't effect Södra's clients, an extension of the duration time from one to five years would be good.
If Södra don't extend the duration time of the contracts my recommendation is to have fewer contracts. The possibility to change between the contracts ''average last three months'' and ''average current month'' every other year is the weakest point of today's system. Therefore I recommend stop selling pulp to the contract ''average PIX last three months''.
We can't prove any longterm difference between the contracts. If Södra chooses to have just one contract from this point of view it does not matter which one they choose. However, it seems like a good idea to follow the global market and therefore I recommend to choose ''average PIX current month'' rather than ''average PIX last three months'' which lags behind the market front. Since the price ''average current month'' is available at FOEX web page I think Södra should choose this contract if they decide to have only one contract.
Södra Cell säljer årligen 1 900 000 ton pappersmassa. Av denna mängd säljs 490 000 ton enligt ett kontraktsystem baserat på ett prisindex som heter PIX NBSK. Detta index introducerades 1996 och reflekterar priset på pappersmassa gjord av barrträd. Jag studerar priset på indexet från Oktober 1996 till December 2006.
Dagens kontraktsystem är baserat på kontrakt med löptiden ett år. Jag undersöker om man kan prediktera prisskilllnaden mellan kontrakten, dra nytta att dagens löptid som bara är ett år och välja det kontrakt som ger det billigaste priset så ofta att priset över lång tid reduceras. När man predikterar gör man en uppskattningen av framtiden utifrån en modell av hur framtid beror på dåtid och nutid. Den modell jag har använt kallas ARMA. Denna tillsammans med priserna på pappersmassa från 1975 och framåt gav mig ett fruktbart sätt att förutsäga priserna. Resultatet blev ett pris reducerat med 0.81% i medel under perioden 1996-2006. Eftersom Södra ha så stor försäljningsvolym skulle de ha förlorat 2.27 miljoner dollar per ton i medel om alla kunder ha spekulerat utifrån den modellen jag använde.
Om dagens kontraktsystem hade börjat användas 1975 med listpriserna som bas hade en kund som använt min prediktionsmetod fått ett pris reducerat med 0.57% under perioden 1986-2006.
Om kunderna i förväg hade vetat priset under 1996-2001 gav det nuvarande systemet en reducerad medelintäkt med 1.5% av priset. Enskilda år reducerades intäkten med så mycket som 3%. Beräknar man konfidensintervall för prisreduktionerna så inser man att på lång sikt kommer dessa vara av storleksordningen 0.4-2.7% med sannolikheten 95%. Detta förutsatt att klienterna kan se in i framtiden. Siffran 2.7% alltså ett mått på hur stor risk man tar med dagens system. Jag tror inte att klienterna kommer reducera priset med 2.7% med nuvarande system, men det är en övre gräns.
De gynsamma prediktionerna har sitt ursprung i att det finns periodicitet i priserna. Jag undersöker denna periodicitet med spektralanalys. Periodiciteten för PIX indexet är starkast kring 5 år. En wavelet-approximation av PIX-indexet hade störst periodicitet kring 3.4 år. Listpriserna hade starkast periodicitet kring 5.6 år. Detta indikerar att den nuvarande löptiden, ett år, är för kort. En lämpligare löptid för kontrakten är 5 år.
Förmodligen är fem års löptid alltför lång tid att binda sig för många kunder. Därför föreslår jag att man reducerar antalet kontrakt istället. Den största svagheten i dagens system är den korta löptiden tillsammans med kontrakten ''average current month'' och ''average last three months''. Jag rekommenderar att man slutar erbjuda kontraktet ''average last three months''. Det allra säkraste är att endast erbjuda ett kontrakt. Vi har inte kunnat påvisa några skillnader över lång sikt mellan kontrakten såtillvida att något kontrakt skulle ge ett lägre medelpris än ett annat. Ur den aspekten är det godtyckligt vilket kontrakt man väljer, men det verkar vettigt att följa den globala marknaden. Därför är det eftersläpande kontraktet ''average PIX last three months'' inte att rekommendera, välj heller ''average PIX current month''. Ett annat argument för att välja ''average PIX current month'' är att dessa priser finns på FOEX hemsida och inga extra beräkningar behöver göras.

Full textStress och psykosomatiska symtom är ett ökande problem i dagens samhälle där ungdomar är speciellt utsatta. Stress har som begrepp utvecklats under årens gång, men kopplas idag ihop till flera kroniska sjukdomar, nedstämdhet och hjärt- och kärlsjukdomar. Människor utsätts idag för långvarig, kronisk stress, vilket kroppen inte är konstruerad för. Kvinnor verkar generellt sett uppleva mer stress i vardagen än män, vilket kan kopplas till samhällets syn på kön och genus. Detta kan även kopplas till hur män och kvinnor hanterar stress, vilket verkar vara annorlunda. Ytterligare så kan känsla av sammanhang kopplas till stress, där en högre känsla av sammanhang har en samband med lägre stress och tvärt om. Forskare menar att graden av känsla av sammanhang ökar med åldern, vilket då även kan kopplas till en lägre stressnivå vid högre ålder. Dock behövs mer forskning för att fastställa detta. Syftet med studien är att undersöka om det finns ett samband mellan ålder, kön, typ av utbildning och stress. Studien har ett bekvämlighetsurval med totalt 79 respondenter, varav 56 kvinnor och 23 män. Resultatet i denna studie visar inte på någon signifikant skillnad mellan kön, ålder och utbildning i relation till stress, då endast vissa små skillnader identifieras i den deskriptiva analysen. För att kunnat få ett signifikant resultat hade studien behövt ha en annan typ av urval och ett större antal respondenter.

Next, fractal dimensions of the these songs are calculated by using two different method and two different scattering diagrams. In the first method, fractal dimensions are calculated via two different box sizes. As for second method, successively decreased box sizes are used. In addition, standard deviation and mean values of the fractal dimensions are calculated to check the relation between fractal dimension and maqam. T test and F test are applied to check the statistical significance. After these calculations, it is verified that fractal dimension can be used as an information source concerning the Turkish art music songs which are nonlinear dynamical systems. Moreover, it is showed that maqams can have their own fractal dimension for low resolutions. On the other hand, it is seen that for high resolutions all songs have almost same fractal dimension.

Full textOur thesis does not deal with clinical depression but with the issue of loss within the psychic functioning of patients marked by a schizophrenic process. By issues of loss we mean all situations in which the patient has lost something, but also separation, depression, melancholy and grief. In order to examine the standard metapsychological function and to observe the articulations and entanglements existing between issues of loss and dissociative problems we surveyed the functions of loss associated with a personality that had lost its sense of confines and existence beyond the purely symptomatic aspect of depression. Our first hypothesis is that the more psychic functions are marked by a schizophrenic process inhabited by object representations, even if these representations are partial, persecuting, poorly differentiated or incestuous, the more the thought remains " alive " even if it is disorganised. A second hypothesis is that in schizophrenic patients there is no possibility of developing issues of loss. The presence of depressive elements can however signal a partial easing of psychotic defenses. A sub-hypothesis is that the recognition of the problem of loss is possible in dysthymic patients but that the treatment differs from that aimed at grief and melancholy. A third hypothesis centres around the existence of a melancholic process in some schizophrenics (dysthymia). To test these hypotheses we studied the psychic functioning of twenty patients diagnosed as " schizophrenic "according to CIM 10. This was based on projective mediation tests (Rorschach and TAT) looking at differences and invariables associated with the treatment of loss and depression. We demonstrated the specificity of psychic functioning for each schizophrenic in terms of relationships, emotions and sensations relating to the issue of loss. Our results demonstrate that the functioning of patients affected by schizophrenia, far from remaining focused on one object tends instead to defend itself from the influence of the object upon the ego. Behind a more delusional and hallucinatory appearance the mental functioning of patients with paranoid schizophrenia and dysthymia is more disorganised, but paradoxically " more alive ", more driven by representations of objects that appear as an outward expression of less deadly psychic functioning, this despite the noisier symptoms in the form of simple undifferentiated or hebephrenic schizophrenia. Our work shows that if problems and depressive effects can be seen they lead to different defensive treatments which are invariably underpinned by denials. The presence of isolated depressive effects does not lead to recognisable problems associated with loss for the patient. We therefore conclude that if schizophrenics recognise situations of loss then that cannot be the work of psychic integration. This impossibility depends on the intensity of the destructive schizophrenic process and the capacity to implement a narcissistic reinvestment in itself, even if only transitory, albeit with significant individual differences. Finally, if we examine the outlines of the melancholy movements within our participants, they cannot be carried through to the end because of the inconsistency of the object lost, its potentially persecuting character and the absence of self/non-self limits

Full textThe study present analyzes the relation between work accident and human values. It was developed with the sample of 156 operators of a factory, through to an application of structured questionnaires. The data were submitted to quantitative analyses (for example, analyses of frequency distributions, Chi-Square, test t). It was verified that 27 employees that filled out the questionnaires suffered work accidents. The results evidence that there aren?t significant differences between the people s values that suffered work accidents and those that did not suffer. The employees presented a hierarchy of different values comparing with the others Brazilian studies. It was observed that the work accidents varies for organizational sectors. So, we get the conclusion, the occurrence of the work accidents is not associated to the values, but they are probably associated to work conditions
O presente estudo analisa a rela??o entre os acidentes de trabalho e os valores humanos. Foi desenvolvido com uma amostra de 156 operadores de uma f?brica, atrav?s da aplica??o de question?rios estruturados. Os dados foram submetidos a an?lises quantitativas (por exemplo, an?lises das distribui??es de freq??ncia, teste t e qui-quadrado). Verificou-se que 27 funcion?rios que preencheram os question?rios sofreram acidentes de trabalho. Os resultados apontam que n?o h? diferen?as significativas entre os valores daqueles que sofreram acidentes e os que n?o sofreram. Os participantes apresentaram uma hierarquia de valores diferente de outras amostras pesquisadas nos Brasil. Constataram-se diferen?as de freq??ncia de acidentes por setores da empresa. Verificou-se, ent?o, que, a ocorr?ncia dos acidentes de trabalho n?o est? associada aos valores, mas mais provavelmente ?s condi??es de trabalho

Full textSyftet med uppsatsen är att analysera hur ett antal makrovariabler påverkar på och samverkar med priserna på småhus. Även hur variablerna reagerar på chocker sinsemellan studeras.
Tidsserieanalysen bygger på månadsdata från år 1996 fram till 2006, som innehåller alla försäljningar av småhusfastigheter i hela Sverige. Det kvalitetsindex som används för att analysera priserna är K/T- talet. För att studera skillnader, avseende samverkan och påverkan, regioner emellan görs en uppdelning av landet i regionerna Stockholm, Göteborg, Malmö, Glesbygd samt hela Sverige. För att testa olika makrovariablers påverkan på K/T- talen används Grangers kausalitets test. Resultaten av dessa test visar att K/T- talen påverkas på annorlunda sätt i de olika regionerna.
Fortsatt analys sker med estimering av en enkel vektorautoregressiv modell för varje region, där de tre endogena variabler K/T- tal för regionen, industriordrar och nybilsregistrering används. Sedan utförs impulsrespons chocker på de tre endogena variablerna. Den starkaste effekten som kan urskiljas av dessa chocker är att K/T- talen har en inverkan på hushållens förmögenhet och då även dess konsumtion.
