Social Policy and Poverty: Checking The Efficiency of The Social Assistance System in Poland
No full textThe study examines distribution and impact of the transfers directed by definition to thelow income
population (hereafter: the social assistance). During the period observedboth the volume and the
number of recipients increased considerably. Those benefits appeared to be fairly effective as a tool
preventing the non-poor from falling intopoverty and quite successful in supporting the poor in
escaping from poverty. Most of
the types of households exposed to higher than average risk of poverty are less likely to
be discriminated in receiving social assistance. The analysis of behavioural response confirmed
relatively high proportion of foregone income.4
Empirical versus policy equivalence scales: matching estimation
No full textProperties of three types of equivalence scales obtained through the matching estimations are compared. The scales are derived
by estimating the effect that demographic variables have on the houshold expenditures. The types estimated include: i/
matching on common values of well-being covariates (partly normative approach), ii/ matching on simulated quivalent
expenditure minimising the deviation between the estimated and persumed value (solely empirical method), iii/matching on
covariates with imposed economy of scale on selected commodities (policy scales). Unlike many scales based on the estimates
of demand systems, those obtained by the matching estimation confirm expectations based on the economic theory.2
Wybrane problemy społeczne Laotańskiej Republiki Ludowo-Demokratycznej
No full textLaos wydaje się być nadal państwem pomijanym i niezauważanym przez zachodnie media i opinię publiczną. Pozostaje w cieniu swoich większych sąsiadów, Wietnamu i Tajlandii, które są wpływowymi państwami ASEAN, podczas gdy Laotańska Republika Ludowo-Demokratyczna znalazła się na uboczu regionalnej i światowej polityki. Taki stan rzeczy odnosi się również do rozpoznania przez zachodnich obserwatorów problemów społecznych, z którymi boryka się to państwo.
Niniejszy artykuł koncentruje się na przybliżeniu specyfiki i zdefiniowaniu problemów społecznych, z którymi Laos mierzył się w ostatnich trzech dekadach. Przedstawiona została charakterystyka Laosu, z uwzględnieniem analizy rankingu HDI, by na tym tle odpowiedzieć na pytania dotyczące wyzwań społecznych stojących przed LRLD. Autorzy artykułu wskazują, że problemy te wynikają z faktu, iż jest to kraj średnio rozwinięty i zróżnicowany etnicznie.
Do przeprowadzenia badań posłużyła metoda monograficzna, oparta na analizie zgromadzonych publikacji naukowych, danych statystycznych oraz źródeł internetowych. W wyniku badań udało się potwierdzić następującą hipotezę: nękające Laotańską Republikę Ludowo-Demokratyczną problemy o charakterze społecznym mają swoje źródło przede wszystkim w złej sytuacji materialnej większości obywateli, braku infrastruktury oraz zróżnicowaniu etnicznym społeczeństwa. Z powyższymi problemami rząd w Wientian wyraźnie sobie nie radzi. Patrząc jednak na ogólną tendencję rozwojową Laosu, skala opisanych w pracy problemów powinna się sukcesywnie zmniejszać

Abstract
The aim of the study was to compare the results obtained in the coaching tests (block jump and spike jump) with the results of laboratory tests (counter-movement jump and spike jump performed on force plate) in volleyball players. The study involved 29 players taking part in the competition Polish Volleyball League SA. Characteristics of participants: age 27.3 ± 3.8 years, body height 197.2 ± 6.7 cm, body mass 91.6 ± 8.9 kg, training experience of 7.5 ± 3.5 years. Each volleyball player performed coaching test consisting of three block jumps and three spike jumps, and laboratory test consisting of three counter-movement jump (CMJ) and three spike jump (SPJ) performed on force plate. The mean values obtained by the competitors in the coaching test were: height in block jump 61.5±8.8 cm, height in spike jump 81.1±10.3 cm, and laboratory test: the height of rise of the body’s centre of mass in the CMJ 52.2±5.4 cm and SPJ 63.8 ±8.0 cm. Significant relationship were found between maximal power output in CMJ, SPJ performed on force plate and height of jump obtained during laboratory and coaching tests. In conclusion, height of jumps measured in coaching test significantly differ from the height of rise of the body’s centre of mass measured in jumps on force plate (laboratory tests). Significant relationship were found between maximal power output in CMJ, SPJ performed on force plate and height of jump obtained during laboratory and coaching tests. No relationship were found between the one’s grasp measured in jump of coaching test and the power output obtained in CMJ, SPJ (laboratory test).Buśko Krzysztof, Szulc Adam, Kołodziejczyk Michał.

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
No full text“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
No full textWe 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
No full textWe 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
