Education and Employment Opportunities for the Roma
No full textThe Roma more than anyone else lost out in the transition to the market economy in the countries of Central and South Eastern Europe. Their unemployment rate is 100 per cent in some rural areas and the Roma's dependence on government benefits is widespread. This article takes a look at unemployment and employment among the Roma on the basis of two surveys completed in 2002 and 2004. It is shown that lack of formal education cannot provide a full explanation of the relatively high unemployment rates faced by Roma and that at least part of the problem arises from discrimination in employment. Roma are also disproportionately employed in low-quality jobs in the informal sector. The paper argues that programmes aimed at combatting labour market and income disadvantages of the Roma must be based on the development of opportunities for autonomous income generation rather than the public works temporary employment programmes currently prevalent.

Nuclear envelope-limited chromatin sheets are part of mitotic death
No full textNuclear envelope-limited chromatin sheets (ELCS) are enigmatic membranous structures of uncertain function. This study describes the induction of ELCS in p53 mutated Burkitt's lymphoma cell lines after treatment with irradiation or the microtubule inhibitor, SK&F 96365. Both treatments evoked similar mitotic death, involving metaphase arrest followed by extensive endopolyploidisation and delayed apoptosis, although the kinetics were different. We found that induction of ELCS and nuclear segmentation correlated with the amount and kinetics of M-phase arrest, mitosis restitution and delayed apoptosis of endopolyploid cells. In metaphases undergoing restitution, ELCS are seen participating in the restoration of the nuclear envelope, mediating the attachment of peripheral chromatin to it. In interphase cells, ELCS join nuclear segments, ectopically linking and fusing with heterochromatin regions. In cells with segmented nuclei, continued DNA replication was observed, along with activation and redistribution of Ku70, suggestive of non-homologous DNA end-joining. Induction of ELCS also parallels the induction of cytoplasmic stacked membrane structures, such as confronting cisternae and annulate lamellae, which participate in the turnover and degeneration of ELCS. The results suggest that arrest at a spindle checkpoint and the uncoupling of mitosis from DNA replication lead to the emergence of ELCS in the resulting endopolyploid cells
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
