Education and career of librarians and information specialists in Great Britain
Polona Vilar
Knji?nica : Revija za Podro?je Bibliotekarstva in Informacijske Znanosti , 1999,
Abstract: A three-month's study m Great Britain, serving as a backgr und for this paper, enabled the author to familiarize herseIf with the situation in the library and information field in Britain, and get acquainted with the educational process as well as with the carreer possibilities for graduates of undergraduate or postgraduate programmes of library and information science and or management. Lately, the postgraduate programmes seem to be gaining greater importance. A presentation of the British university system, the study itseIf and of the programmes is given. The paper also mentions the needs and requests put before librarians and information managers by the industry and market. We also find a short presentation of the Library Association, the British professional association of libraries. Its major task is care of the quality of education as well as library and information services through accreditation of courses and maintenance of the Register of Chartered Members, both of which are presented in the paper.In the conclusion we find the opinion that the role of librarians and information managers needs to be changed in order to satisfy the challenges and possibilities put before them by the information and knowledge sector, which is one of most rapidly developing industry areas. However, to achieve this goal we have to have quality formal and permanent education.
Information behaviour: models and concepts
Polona Vilar
Knji?nica : Revija za Podro?je Bibliotekarstva in Informacijske Znanosti , 2005,
Abstract: The article presents an overview of the research area of information behaviour. Information behaviour is defined as the behaviour of individuals in relation to information sources and channels, which results as a consequence of their information need, and encompasses passive and active searching of information, and its use. Theoretical foundations are presented, as well as some fundamental conceptual models of information behaviour and related concepts: information searching behaviour, which occurrs in active, purposeful searching for information, regardless of the information source used; and information seeking behaviour, which represents a micro-level of information searching behaviour, and is expressed by those individuals who interact with information retrieval systems.

Sampling Error Estimation in Stratified Surveys  [PDF]
Ricardo Cao, José A. Vilar, Juan M. Vilar, Ana K. López
Open Journal of Statistics (OJS) , 2013, DOI: 10.4236/ojs.2013.33023
Abstract:

Many operations carried out by official statistical institutes use large-scale surveys obtained by stratified random sampling without replacement. Variables commonly examined in this type of surveys are binary, categorical and continuous, and hence, the estimates of interest involve estimates of proportions, totals and means. The problem of approximating the sampling relative error of this kind of estimates is studied in this paper. Some new jackknife methods are proposed and compared with plug-in and bootstrap methods. An extensive simulation study is carried out to compare the behavior of all the methods considered in this paper.

Noisy-threshold control of cell death
Jose MG Vilar
BMC Systems Biology , 2010, DOI: 10.1186/1752-0509-4-152
Abstract: Here, I show that these typical responses arise naturally from the interplay of intracellular variability with a threshold-based control mechanism that detects cellular changes in addition to just the cellular state itself. Implementation of this mechanism in a quantitative model for T-cell apoptosis, a prototypical example of programmed cell death, captures with exceptional accuracy experimental observations for different expression levels of the oncogene Bcl-xL and directly links adaptation with noise in an ATP threshold below which cells die.These results indicate that oncogenes like Bcl-xL, besides regulating absolute death values, can have a novel role as active controllers of cell-cell variability and the extent of adaptation.Cells in multicellular organisms have the ability to actively control their own death and engage in an organized self-destruction process known as programmed cell death, or apoptosis. This ability is necessary in many situations, ranging from embryonic development to the maintenance of mature organisms, and its deregulation is a hallmark of cancer [1] and many other diseases [2].Apoptosis can be triggered by a variety of internal or external stimuli, such as specific death signals, lack of growth factors, DNA damage, and different types of stress [3]. These stimuli frequently converge with the metabolic state of the cell into the mitochondrial pathway, which promotes apoptosis through activation of the caspase cascade by releasing cytochrome c into the cytosol [3-5]. Low intracellular ATP levels favor the release of cytochrome c, resulting in high apoptotic rates [6,7]. In this way, the absence of nutrients or signals that stimulate metabolism triggers apoptosis in a wide variety of cell types (Figure 1A).The coupling of metabolism with apoptosis is remarkably important in cancer, especially because many anticancer drugs targeted against growth promoting pathways selectively induce apoptosis in cells with highly upregulated metabolism [8-
The domestic work of consumption: materiality, migration and home-making
Rosales,Marta Vilar;
Etnográfica , 2010,
Abstract: this article aims to discuss the potentials of an integrated approach to two significant fields of practice: materiality and migration. based on the results of a preliminary approach to the portuguese migrant community in toronto and three previous ethnographies with portuguese and indi-portuguese migrants conducted in lisbon, maputo and four brazilian cities, it intends in particular to explore the various ways in which the home and home-making as a social and cultural process can work as a significant field to explore that relation. it will be argued that domestic materiality constitutes a particularly productive field to look at the relationships between macro-contexts and micro-practices, social formations and cultural institutions that affect and shape the life experiences of those who migrate. in order to discuss its participation in the evaluations, reconfigurations and processes of rebuilding?/?reconstructions that necessarily take part in all migratory movements, the work of domestic consumption will be addressed as an expression of those processes but also as a constitutive activity, i.?e., the (re)production of identity and belonging.
LAS ADR EN LA JUSTICIA DEL SIGLO XXI, EN ESPECIAL LA MEDIACIóN
Barona Vilar,Silvia;
Revista de derecho (Coquimbo) , 2011, DOI: 10.4067/S0718-97532011000100008
Abstract: this essay seeks to expose not very much analyzed experiences by the legal systems of the continental europeans, but very well known by the anglo-saxon systems. the stated goal is to encourage debate on these alternatives to resolve conflicts in society, with special attention to mediation.
Stemming of Slovenian library science texts
Polona Vilar,Jasna Maver
Knji?nica : Revija za Podro?je Bibliotekarstva in Informacijske Znanosti , 2002,
Abstract: The theme of the article is the preparation of a stemming algorithm for Slovenian library science texts. The procedure consisted of three phases: learning, testing and evaluation.The preparation of the optimal stemmer for Slovenian texts from the field of library science is presented, its testing and comparison with two other stemmers for the Slovenian language: the Popovi stemmer and the Generic stemmer. A corpus of 790.000 words from the field of library science was used for learning. Lists of stems, word endings and stop-words were built. In the testing phase, the component parts of the algorithm were tested on an additional corpus of 167.000 words. In the evaluation phase, a comparison of the three stemmers processing the same word corpus was made. The results of each stemmer were compared with an intellectually prepared control result of the stemming of the corpus. It consisted of groups of semantically connected words with no errors. Understemming was especially monitored – the number of stems for semantically connected words, produced by an algorithm. The results were statistically processed with the Kruskal-Wallis test. The Optimal stemmer produced the best results.It matched best with the reference results and also gave the smallest number of stems for one semantic meaning. The Popovi stemmer followed closely. The Generic stemmer proved to be the least accurate. The procedures described in the thesis can represent a platform for the development of the tools for automatic indexing and retrieval for library science texts in Slovenian language.
