How schools influence students' academic achievements: a behavioral approach with empirical evidence from add health data.
Get PDFThis paper proposes a behavioral model to study how schools influence students’ educational behavior and academic achievements. The school quality is then defined into two dimensions: the amount of market-valued skills schools impart and how well schools cultivate an educational identity. Using data from Add Health in the US, I test the major hypotheses from the theoretical model. On the one hand, school resources (average class size and teacher supply) and student-level curriculum have some effects on the math GPA scores. On the other hand, educational identity indicators (school-level happiness and participation at school teams, clubs or organizations) and the previous math GPA scores are significant determinants in students’ observable effort level such as absenteeism behavior, and through this channel both determinants indirectly influence math GPA achievement. These empirical results inform us that an identity-based behavioral model adds to a rational expectation educational choice model in understanding the widening academic achievement gap between adolescents from different socioeconomic backgrounds. The paper presents the limitation of using school resources to study the school quality and advocates a richer set of school quality measures.
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Vyhodnocení dopadu bankovní regulace na stabilitu bankovního sektoru v členských státech EU ze střední a východní Evropy
No full textThe thesis studies the impact of European banking regulatory reforms on the stability of Central and Eastern European countries after the financial crisis with the annual data from Hungary, Poland, Slovakia, and Slovenia from 2009 to 2019. The thesis reaches several conclusions. Firstly, increasing minimum Tier 1 capital adequacy ratio through CRR/CRD IV did not significantly promote the bank stability in sample countries. However, total capital adequacy ratio is found to have positive and significant association with overall insolvency risk. Secondly, relaxing restrictions would have negative impact on bank stability measured by bank z-score. Thirdly, countries that are more open on the regulation may have more stable banks, while tighter entry restrictions boost bank fragility. Fourthly, when only taking deposit insurance variables as explanatory variables, increasing the level of deposit insurance coverage may dampen the bank stability. However, when controlling other regulation and supervision indexes, the results do not show any significant effect of deposit insurance scheme on bank z-score. Lastly, the supervisory variables are not significantly associated with bank stability in sample countries.Tato práce studuje dopad evropských bankovních regulačních reforem na stabilitu zemí střední a východní Evropy po finanční krizi s ročními údaji z Maďarska, Polska, Slovenska a Slovinska od roku 2009 do roku 2019. Práce dospívá k několika závěrům. Zaprvé, zvýšení minimálního poměru kapitálové přiměřenosti Tier 1 prostřednictvím CRR / CRD IV významně nepodpořilo stabilitu bank ve vybraných zemích. Ukazuje se však, že poměr celkové kapitálové přiměřenosti je pozitivně a významně spojen s celkovým rizikem platební neschopnosti. Zadruhé, uvolnění omezení by mělo negativní dopad na stabilitu banky měřené z-skóre banky. Zatřetí, země s otevřenějšími přístupy k regulaci a dohledu mají tendenci mít stabilnější banky, zatímco přísnější omezení vstupu zvyšují křehkost bank. Začtvrté, vezmeme-li pouze proměnné pojištění vkladů jako vysvětlující proměnné, může zvýšení úrovně krytí pojištění vkladů ztlumit stabilitu banky. Při kontrole ostatních indexů regulace a dohledu však výsledky neukazují žádný významný vliv systému pojištění vkladů na z-skóre banky. A konečně, proměnné dohledu nejsou významně spojeny se stabilitou bank ve vybraných zemích.Katedra ruských a východoevropských studiíDepartment of Russian and East European StudiesFaculty of Social SciencesFakulta sociálních vě
Variations on the Author
Get PDF“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
Get PDFWe 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
Visegrad Group: Transition of banking sector from "single bank" system to the current global commercial banking system
No full textThe aim of this dissertation is to provide a detailed quantitative and qualitative assessment of the banking system currently in place in the Visegrad countries, as well as its transition from the Soviet system to a capitalist market-oriented system. The empirical part of this study focuses on estimating the stability of the banking system, the impact of regulations and supervision on the stability of this system the performance and effectiveness (productivity) of the system, and the impact of banking sector performance on economic growth. Two different methods are used for the data analysis: panel data regression with random effect model and traditional ratio analysis based on DuPont formula and other financial ratios, which were constructed using historical data taken from Bank Scope, together with random-effects GLS regression. The results suggest that, as measured by z-score, Slovakia had the most stable banking sector in most years, followed by Poland, Hungary, and the Czech Republic. Additionally, according to the regression analysis, the imposition of strict requirements for banks applying for licenses in Visegrad countries has led to greater banking system stability, while prohibiting additional banking activities-such as real estate, insurance, securities, or other non-financial..

Empirická časť tejto štúdie sa zameriava na meranie stability bankového systému a skúma aký majú prísnejšie regulácie a dohľad vplyv na stabilitu bankového systému, ďalej skúma výkonnosť a efektivitu (produktivitu), a vplyv výkonnosti bánk na celkový rast. Použila som dva typy metód na analýzu: regresia panelových dát s "random" efektom a tradičné meranie na základe pomerov s použitím Du Pontovej formuly a iných finančných ukazovateľov skonštruovaných z historických dát z Bank Scope spolu s "random" efekt GLS regresiou. Podľa výsledkov z-skóre, Slovenská Republika má najstabilnejší bankový systém vo väčšine skúmaných rokov, za ňou nasleduje Poľsko, Maďarsko a Česká Republika. Naviac, podľa výsledkov regresnej analýzy, prísne požiadavky na vstup na trh a získanie bankovej licencie vo Vyšehradských krajinách vedú k vyššej stabilite bankového sektoru kým zákaz alebo obmedzovanie bankových aktivít ako napríklad nehnuteľnosti, poisťovníctvo, akcie, alebo iné nefinančné operácie vedie k nižšej stabilite bankového systému celkovo. Taktiež sme zistili, že v...Department of Russian and East European StudiesKatedra ruských a východoevropských studiíFaculty of Social SciencesFakulta sociálních vě
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
