Finite de Finetti-Type Results as Approximation Results by the Expectation of Sufficient Statistics

Pötzelberger, Klaus January 1995 (has links) (PDF)
We show that finite de Finetti-type results may be viewed as results on the approximation of certain continuous functions of a parameter by a sequence of positive operators (Ln) . For distribtions that depend on a finite-dimensional statistic (Tn) only, Ln is the expectation operator of (Tn) under the extremal infinite exchangeable distributions. The rate of approximation of finite exchangeable distributions by mixtures of marginals of infinite exchangeable distributions is the rate of approximation of a single function of the parameter, namely the second indefinite integral of the Fisher information. Our results include a major part of what is known about finite de Finetti theorems. The theory is, however, not only valid for the case when the extremal infinite exchangeable distributions are products of identical distributions. It applies as well to Markov-exchangeable distributions or the linear model. Moreover, the metric is not restricted to the supremum norm.

Direct Search Methods for Nonsmooth Problems using Global Optimization Techniques

Robertson, Blair Lennon January 2010 (has links)
This thesis considers the practical problem of constrained and unconstrained local optimization. This subject has been well studied when the objective function f is assumed to smooth. However, nonsmooth problems occur naturally and frequently in practice. Here f is assumed to be nonsmooth or discontinuous without forcing smoothness assumptions near, or at, a potential solution. Various methods have been presented by others to solve nonsmooth optimization problems, however only partial convergence results are possible for these methods. In this thesis, an optimization method which use a series of local and localized global optimization phases is proposed. The local phase searches for a local minimum and gives the methods numerical performance on parts of f which are smooth. The localized global phase exhaustively searches for points of descent in a neighborhood of cluster points. It is the localized global phase which provides strong theoretical convergence results on nonsmooth problems. Algorithms are presented for solving bound constrained, unconstrained and constrained nonlinear nonsmooth optimization problems. These algorithms use direct search methods in the local phase as they can be applied directly to nonsmooth problems because gradients are not explicitly required. The localized global optimization phase uses a new partitioning random search algorithm to direct random sampling into promising subsets of ℝⁿ. The partition is formed using classification and regression trees (CART) from statistical pattern recognition. The CART partition defines desirable subsets where f is relatively low, based on previous sampling, from which further samples are drawn directly. For each algorithm, convergence to an essential local minimizer of f is demonstrated under mild conditions. That is, a point x* for which the set of all feasible points with lower f values has Lebesgue measure zero for all sufficiently small neighborhoods of x*. Stopping rules are derived for each algorithm giving practical convergence to estimates of essential local minimizers. Numerical results are presented on a range of nonsmooth test problems for 2 to 10 dimensions showing the methods are effective in practice.

Har bolagiseringen av idrottsföreningar gett önskad effekt? : En fallstudie om idrottsaktiebolag ger bättre finansiella nyckeltal samt bättre sportsligt resultat

Brunn Olausson, Sandra, Novakovic, Dejan January 2013 (has links)
Bakgrund och problem: År 1999 blev det tillåtet för idrottsföreningar med elitverksamhet att bilda aktiebolag. I dag har endast 23 stycken idrottsföreningar av ungefär 20 000 valt att bilda aktiebolag som man upplåtit sin serieplats till. Inför Riksidrottsmötet 1997 lämnade AIK, Svenska ishockeyförbundet samt några enstaka mindre föreningar in en motion om att idrottsföreningar skulle få möjlighet att driva föreningen i en alternativ assoicationsform. Argumentet för denna motion var att detta skulle ge en möjlighet för svensk idrott att kunna konkurrera sig med internationella föreningar. En bättre ekonomi skulle ge bättre sportsliga resultat. För att kunna närma sig den internationella nivån behövs stora finansiärer, vilket man inte hade möjlighet till genom den associationsform föreningar var tvungna att bedrivas som. Problemformulering: Ger bolagiseringen bättre ekonomiska och sportsliga resultat? Syfte: Syftet med denna studie är att undersöka hur föreningens finansiella resultat och sportsliga resultat påverkas av den nya bolagiseringen. Metod: Studien har genomförts som en kvantitativ fallstudie på fyra stycken fotbollsföreningar som bildat aktiebolag. Ekonomiska värden och tabellposition har sedan analyserat för idrottsAB från 1999 till 2011 samt över alla lagen i allsvenskan 2011 och superettan 2011. Studien innehåller även kvalitativa inslag. Slutsats: Slutsatsen är att bolagiseringen av elitverksamheten för föreningar varken ger ekonomiska eller sportsliga lyft. / Background and problem: In 1999 it became allowed for sport clubs to run their clubs as a company. In Sweden today, there is only 23 of approximately 20000 sport clubs that runs their club as a company. in 1997, before the swedish national sport meeting, a few clubs, such as AIK, and the Swedish Icehockey Association submitted a motion that included a request that the clubs could be runned in an another legal form. The main reason for this motion was that it would give the clubs other opportunities for financing, and that would make the clubs competitive in Sweden such as international. To approach the international clubs, the clubs in Sweden needed major external financiers, which was not allowed before.A better economy at the clubs whold lead to better results on the pitch. Problem formulation: Does the corporatisation of the Swedish football clubs give better economic-and sport results? Purpose: The purpose of this study is to find out how the economic and sport results depend on the corporatisation. Method: This case studie has been performed with a quantitative method on four football companies in the two major leagues. Economical values and the positions in the leagues between 1999-2011. There is also a comparision between the companies and the other clubs in the league for 2011. The studie also includes qualitative elements. Conclusion: The conclusion is that the corporatisation of the Swedish football clubs does not affect the economic results and sport results.

"Det respektfulla bemötandet" : En studie om medarbetares uppfattningar av två kompetensutvecklingsinsatser samt metoderna för dessa.

Lindström, Anna January 2014 (has links)
SammanfattningI kunskapssamhällets nuvarande form är kompetensutveckling ett dominerande begrepp i sammanhang för vuxnas lärande. Kompetensutvecklingsinsatser kan ses som ett av de sätt genom vilket lärande sker för organisation, verksamhet och individ. Dock finns ingen given relation mellan en kompetensutvecklingsinsats och lärande. Kompetensutveckling är ett sätt att utveckla verksamheten och medarbetarnas lärande. Detta sker både med formella och informella insatser utifrån varierande syften samt mål.Utvärderingar undersöker ofta resultaten och medarbetarnas utveckling genom lärande samt kunskap i relation till avsatt mål för kompetensutvecklingsinsatsen utifrån ett företagsperspektiv. Men vad kan egentligen kompetensutvecklingsinsatser innebära för medarbetarna i en verksamhet?Syftet med denna studie är att undersöka medarbetarnas uppfattningar av två kompetensutvecklingsinsatser samt metoderna för dessa inom verksamhetsområdet ”Aktivitet och Upplevelse” inom Uppsala Kommun. Studien syftar även till att undersöka medarbetarnas uppfattning av resultaten för kompetensutvecklingsinsatserna i relation till deras arbete på arbetsplatserna. Studien genomfördes med fokusgruppintervjuer. Resultatet av studien visar att informanterna uppfattade kompetensutvecklingsinsatserna som en introduktion och en grundutbildning för metoderna Sherborn och Taktipro, samt att metoderna innebar ett tankesätt som präglade medarbetarnas vardagliga arbete i verksamheten.

YMCA a Vysokoškolský sport jako průkopníci volejbalu v Českých zemích / YMCA and University sport as pioneers of volleyball in Czech countries

Šarochová, Klára January 2013 (has links)
Title: YMCA and University sport as pioneers of volleyball in Czech countries Objectives: The goal of our thesis is to make an overview of beginning and development of volleyball between first and second world war in Czech countries and to prove the influence of YMCA and University sport on it. Methods: We have used these methods in our thesis: progressive and retrospective method, direct and indirect method and comparative method. The necessary part of a retrospective and progressive method were synchronous and diachronic attitude to a historical progress. Results: The thesis provides an overview of information related to the formation and development in a period between World War I and World War II in the Czech lands with contribution of the YMCA organisation and the University Sport organisation. The paper demonstrates that these two organisations had the major role in the development of volleyball and thanks to them volleyball in our lands is one of the best ones in Europe from its beginning, in a matter of both its level and organisation. The objectives and partial objectives of the thesis have been fullfiled. Keywords: Clubs, results, tournament, competition, players, championship

L'établissement public, mode de gestion de la politique culturelle de l'Etat / The Public Establishment : Management of the State's Cultural Policy

Moraud, Julien 12 December 2013 (has links)
Le régime de la tutelle sur les établissements publics, et les conditions de la coopération, appréhendées selon les critères classiques du droit administratif, ne permettent qu'une conduite imparfaite de la politique culturelle de l'État. Les établissements publics sont un objet : le ministère de la Culture établit avec ces personnes publiques dotées d'une autonomie des rapports inégaux qui ne peuvent fonder la mise en œuvre d'une politique publique cohérente.Les finances publiques enrichissent cependant le droit public et en modifient les instruments administratifs : la loi organique relative aux lois de finances crée de nouveaux rapports entre l'État et les entités en charge de l'exécution d'un service public. L'opérateur de l'État est le point d'entrée d'une gouvernance inédite et de l'introduction de la performance au sein des établissements publics nationaux. Par ailleurs, de nouvelles structures de coopération se mettent en place, qui enrichissent les critères de l'établissement public.La contractualisation de la performance, dont il convient d'étudier les possibilités de l'étendre aux structures de coopération, est un moyen de faire de l'établissement public un acteur de la gouvernance culturelle : de nouvelles connexions s'établissent, les gestionnaires des structures culturelles doivent rendre des comptes. En retour, la généralisation de cette dynamique de contractualisation serait un moyen pour l'État de mener une réflexion inédite sur la détermination et la conduite de la politique culturelle, à partir de ses modes de gestion. / The mode of supervision of public establishments, together with the cooperation conditions, understood on the basis of the classical criteria of administrative law, only allow for an imperfect conduct of the state's cultural policy. The public establishments are an object: The Ministry of Culture establishes relations with these public entities that are on unequal footing and cannot provide a basis for the implementation of a coherent public policy.However, public finances add to the wealth of public law and modify its administrative instruments : the loi organique relative aux lois de finances (Organic Law on Laws of Finance of August 1, 2001) establishes new relations between the state and the entities responsible for the implementation of a public service. The state operator represents the entrance point of a new governance that introduces the notion of performance within national public establishments. Further, new cooperation structures are being put into place that enrich the criteria of public establishments.The fact that performances are contractually defined – and the extension of this system to cooperation structure should be examined – can turn the public establishment into a player in the field of cultural governance: New connections are established, the managers of cultural structures are made accountable. In return, the wider application of this contracting dynamic would provide the state with a unique opportunity to reflect on how to determine and conduct a cultural policy based on these forms of managements.

Elevinflytande i en resultatstyrd skola : En diskursanalys av hur elever och läroplan talar om elevinflytande / Pupil Influence in a Results-oriented School

Nordahl, Annika January 2016 (has links)
Pupil influence is supported by UN convention and legal text, yet it seems to be difficult to realize in school practice. Meaning and purpose of pupil influence appears unclear and can be understood and interpreted in different ways. The aim of this study is to examine, describe and thereby contribute to a better understanding of the phenomenon of pupil influence. The method used is Fairclough’s three- dimensional model for critical discourse analysis. The empirical data consists of focus group interviews with 9th grade pupils and the curriculum, Lgr 11. Four discourses are identified and discussed in relation to the results-driven and market-oriented Swedish school; a learning discourse, an individual discourse, a responsibility discourse and a conditional discourse. The results show that the pupils look upon pupil influence in school in relation to subject knowledge here and now and not as skills to acquire for a future active democratic citizenship. Contrary to the curriculum the pupils articulate pupil influence as a prerequisite for learning. Pupil influence seems to be regarded as individual and personal, and equated with having opportunities to make decisions. Areas possible to practice pupil influence on are characterized by being measurable and to provide a basis for comparison.

Estabelecimento de metas autocontrolado e conhecimento de resultados na aprendizagem de habilidades motoras / Effects of self-establishing goals with different CR conditions in the acquisition of motor skills

Neiva, Jaqueline Freitas de Oliveira 13 May 2019 (has links)
O objetivo do estudo foi investigar os efeitos do autoestabelecimento de metas na aprendizagem de habilidades motoras realizada com diferentes regimes de CR. Para tanto, três experimentos foram realizados, todos eles com três grupos distintos - meta autoestabelecida espontaneamente e de forma induzida e meta externamente controlada ou atribuída - para investigar a aprendizagem da habilidade motora de subir a escada de Bachman, realizada com CR, sem CR e com CR autocontrolado. Os grupos de cada experimento foram tratados como variáveis independentes. Os desempenhos dos participantes foram considerados como variáveis dependentes. As observações originais foram obtidas no ambiente de coleta do experimento por meio da anotação dos degraus subidos pelo aprendiz em cada tentativa. Os desempenhos foram analisados por meio da taxa de desempenho (TxD) caracterizada pelo número de degraus subidos dividido pelo número de degraus possíveis de serem alcançados. Foi realizado um ANOVA two way (3 grupos X 6 blocos) para medidas repetidas no fator bloco. Os dados foram organizados em blocos de 10 tentativas, sendo dois blocos referentes à fase de aquisição (AQ1, AQ30) e dois blocos referentes a cada teste (RET1, RET2, TR1, TR2). Os resultados em todos os experimentos foram semelhantes e os grupos não se diferenciaram entre si. Conclui-se que o processo de aprendizagem dos participantes que estabeleceram suas próprias metas e dos que tiveram a meta atribuída foi semelhante. Assim sendo, o estabelecimento de metas em si, seja atribuída ou externamente controlada (grupo yoked), autoestabelecida espontaneamente ou de forma induzida é favorável para a aprendizagem da tarefa de subir a escada de Bachman, e isso independe se o CR é fornecido, não é fornecido ou é autocontrolado. Conclui-se que pelo fato de tanto o estabelecimento de metas quanto o CR serem reconhecidos como fatores motivacionais eles se neutralizaram e não afetaram a aprendizagem motora de subir a escada de Bachman / This study aimed to investigate the effects of self-set goal on motor skills learning with different KR regimens. Three experiments were carried out, all of them with three distinct groups - spontaneously self-set goal and spontaneously self-directed goal and externally controlled or assigned goal - to investigate the learning of Bachman ladder climbing motor ability, performed with KR, without KR and with self-controlled KR. Groups of each experiment were the independent variables. Participants\' performances were the dependent variables. The original observations were obtained at the experiment data collection environment by notes of the steps reached by the apprentice in each attempt. Performances were analyzed by performance rate (TxD), obtained from the ratio between the number of reached steps and the highest possible step. Two way ANOVA (3 groups X 6 blocks) was performed for repeated measures in the block factor. Data were organized in blocks of 10 trials, two blocks referring to the acquisition phase (AQ1, AQ30) and two blocks referring to retention and transference tests, respectively (RET1, RET2, TR1, TR2). Results in all experiments were similar and its groups not differed from each other. In conclusion, the learning process of the participants who established their own goals and those who had the assigned goal was similar. Thus, goal setting itself, whether attributed or externally controlled (yoked group), self-established spontaneously or in an induced manner is beneficial for learning the Bachman ladder climbing task, regardless if KR is provided or not or if is self-controlled. It is conclued that as the goal setting and KR are both motivational factors, their effects were neutralized and didn\'t affect the motor learning of Bachman ladder task
