Children with their dreams – what kind of reveries are accepted in school context?

2011

The media and the contemporary consumer culture are central categories in modern childhood. They have opened new kinds of experiences and learning situations for children. In this article we are interested in the role of the media and consumption in schoolchildren's daily life. The data consist of writings and drawings of 7–12-year-old schoolchildren. Children have told us about their dreams, social worlds and doings in the mediated world. By asking children about all these things we are most likely able to find out how modern childhood and the learning situations in the class are influenced by the media and consumer goods. It is important to analyse children's experiences in the virtual en…

Computer game as a pragmatic concept : ideas, meanings, and culture

2020

This article discusses the ‘computer game’ as a pragmatic concept. A dual nature of the computer game as both a pragmatic idea and a pragmatic meaning is introduced. Practical meanings of the computer game correspond with the concrete effects that engaging with computer games produces in an individual. Practical ideas of the computer game correspond with the subjectively constituted conceptual families concerning the computer game’s assumed practical meaning. Individual computer games can be considered flat or round depending on the range of their practical meanings. Thus, the article contributes to the study of cultural objects by offering a framework for examining the evolution and existe…

Asistenta pakalpojumu nozīme sociālajā darbā ar cilvēkiem ar invaliditāti: Ogres pilsētā

2016

Maģistra darba tēma - “Asistenta pakalpojumu nozīme sociālajā darbā ar cilvēkiem ar invaliditāti: Ogres pilsētā”. Sociālā darbā pietrūkst novērtēšanas instrumenta, lai precīzi izvērtētu asistenta pakalpojuma apjomu, saturu, noteiktu klienta sociālas funkcionēšanas iespējas un to ierobežojumus. Par pētījuma mērķi izvēlēts izvērtēt asistenta pakalpojumu sociālajā darbā ar cilvēkiem ar invaliditāti Ogrē un piedāvāt novērtēšanas instrumentu asistenta pakalpojumiem. Darbā aplūkots, kādi asistenta pakalpojumu veidi ir pieejami Ogrē; kādi ir šķēršļi asistenta pakalpojumu saņemšanai un administrēšanai; kādi ir sasniegumi, saņemot un administrējot asistenta pakalpojumus, un sniegti ieteikumi, kā uzl…

Treasure Hunts in the Nineteenth and Twentieth Centuries

2012

The religious dimension of the treasure hunt declined as the nineteenth century progressed. The belief in ghosts lost ground or transformed into spiritualism and an interest in the more or less vulgarized forms of what would become known as ‘parapsychology’.1 Without the ghosts who needed to be redeemed, the religious overtones of treasure hunting disappeared. Even news about treasure in an ecclesiastical context was void of spiritual meaning.

Properties of Design-Based Functional Principal Components Analysis.

2010

This work aims at performing Functional Principal Components Analysis (FPCA) with Horvitz-Thompson estimators when the observations are curves collected with survey sampling techniques. One important motivation for this study is that FPCA is a dimension reduction tool which is the first step to develop model assisted approaches that can take auxiliary information into account. FPCA relies on the estimation of the eigenelements of the covariance operator which can be seen as nonlinear functionals. Adapting to our functional context the linearization technique based on the influence function developed by Deville (1999), we prove that these estimators are asymptotically design unbiased and con…

Variance Estimation and Asymptotic Confidence Bands for the Mean Estimator of Sampled Functional Data with High Entropy Unequal Probability Sampling …

2013

For fixed size sampling designs with high entropy it is well known that the variance of the Horvitz-Thompson estimator can be approximated by the Hajek formula. The interest of this asymptotic variance approximation is that it only involves the first order inclusion probabilities of the statistical units. We extend this variance formula when the variable under study is functional and we prove, under general conditions on the regularity of the individual trajectories and the sampling design, that it asymptotically provides a uniformly consistent estimator of the variance function of the Horvitz-Thompson estimator of the mean function. Rates of convergence to the true variance function are gi…

Comments on “Unobservable Selection and Coefficient Stability

2019

Abstract–: We establish a link between the approaches proposed by Oster (2019) and Pei, Pischke, and Schwandt (2019) which contribute to the development of inferential procedures for causal effects in the challenging and empirically relevant situation where the unknown data-generation process is not included in the set of models considered by the investigator. We use the general misspecification framework recently proposed by De Luca, Magnus, and Peracchi (2018) to analyze and understand the implications of the restrictions imposed by the two approaches.

The multichoice consistent value

2000

We consider multichoice NTU games, i.e., cooperative NTU games in which players can participate in the game with several levels of activity. For these games, we define and characterize axiomatically the multichoice consistent value, which is a generalization of the consistent NTU value for NTU games and of the multichoice value for multichoice TU games. Moreover, we show that this value coincides with the consistent NTU value of a replicated NTU game and we provide a probabilistic interpretation.

Global and multiple test procedures using ordered p-values—a review

2004

This paper reviews global and multiple tests for the combination ofn hypotheses using the orderedp-values of then individual tests. In 1987, Rohmel and Streitberg presented a general method to construct global level α tests based on orderedp-values when there exists no prior knowledge regarding the joint distribution of the corresponding test statistics. In the case of independent test statistics, construction of global tests is available by means of recursive formulae presented by Bicher (1989), Kornatz (1994) and Finner and Roters (1994). Multiple test procedures can be developed by applying the closed test principle using these global tests as building blocks. Liu (1996) proposed represe…
