Person-Vocation and person-organization fit.
No full textOrganizational psychologists pay more and more attention to person – work environment fit and there are more and more studies proving positive value of this fit to individual and organizational outcomes. However, this is the lack of research about some of the fit types and the findings about their relationships with other types of fit or outcomes are spare and in some cases inconsistent. The purpose of this study was to explore the relationships between person - vocation and person - organization fit and their association with employee‘s job satisfaction and intentions to leave the organization. In this research we used methods: Vocational interests questionnaire (LPIK); Organizational culture profile (OCP); Minesota satisfaction questionnaire; the questionnaire drawn up by the author of this paper to evaluate employees‘ intentions to leave the organization. 147 employees from four different types of organizations took part in this research. By gender there were 78 man and 69 women. The average age of participants was 31,8 years. The relation between person – vocation and person organization fit was not established in this study. Our work disclosed that it is very important for individual and organization, person to find the right vocation and also to find the right organization. Results show, that person - vocation and person – organization fit were both positive related with employee’s job satisfaction. Moreover, person - organization fit was negative associated with employee’s intentions to leave the organization. The relationship between person – vocation fit and employee’s intention to leave the organization was not established. Our study suggests, that the more vocational interests of the person fits his vocation, the more is he satisfied with his job. And similarly the more persons values fit values of the organization, in which he works, the more is he satisfied with his job and has lower intentions to quit. The hypothesis, that person – organization fit predicts job satisfaction and intentions to leave better than person – vocation fit, was confirmed. The more detailed analyze of this relationships disclosed, that job satisfaction mediate the relationship between person - organization fit and employee’s intentions to leave the organization. This revealed, that relationships between different types of fit is more complex than just a simple direct relationships. Our study together with other studies of this field is the stimulus to concern about person - vocation and person - organization fit and their evaluation at organizational work process and personal selection, which is still focused more on KSA based person - job fit. The revealed importance of both types of fit and limitations of this study suggest the need of future research in this topic

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
SINTETINĖS ŠNEKOS KOKYBĖS VERTINIMAS: KELIŲ KOMPIUTERINIŲ SINTEZATORIŲ LYGINAMASIS TYRIMAS
No full textStraipsnyje pateikiami kelių versijų lietuviškos ir rusiškos sintetinės šnekos suprantamumo ir lietuviškos, rusiškos, vengriškos bei itališkos sintetinių šnekų patrauklumo duomenys. Lietuvių ir rusų diktorių kalba yra suprantamesnė nei atitinkama sintetinė. Ankstesnė rusiškos šnekos sintezė blogesnė nei lietuviška ar patobulinta rusiška sintezė (PRS). Pagal sintetinamų garsų charakteristikas aiškėja dvi priešingos PRS tendencijos - pagal bendrą atpažinimo klaidų mažėjimą ji artėja prie natūralios šnekos, tačiau pagal klaidų homogeniškumą nuo pastarosios tolsta. Kadangi pirmoji tendencija vyrauja, bendra atstojamoji rodo PRS gerėjimą.
PRS suprantamumo ir patrauklumo koreliacija taip pat rodo jos didesnį artumą natūraliai šnekai. Tiriamiesiems PRS yra patrauklesnė nei ankstesnė rusiškos sintezės versija. Pastaroji, tiriamųjų nuomone, panašesne į roboto šneką, o PRS - į blogą, tačiau jau žmogaus šnekos versiją.
Pagal patrauklumo duomenis natūralią šneką labiausiai vertina vengrų klausytojai, o kritiškiausi jos atžvilgiu yra italai. Visos tirtos sintetinių šnekų versijos vertinamos kaip mažiau patrauklios nei natūrali šneka, tačiau jas patobulinus šis vertinimas švelnėja.
EVALUATION OF SYNTHETIC SPEECH QUALITY: A COMPARATIVE STUDY OF SEVERAL COMPUTER-BASED SPEECH SYNTHESIZERS
Albinas Bagdonas, Feliksas Laugalys
Summary
This paper examines some versions of Lithuanian and Russian synthetic speech intelligibility and Lithuanian, Russian, Hungarian and Italian synthetic speech acceptability. The speech of both Russian and Lithuanian speaker is more intelligible than Russian or Lithuanian synthesis. Previous version of Russian synthesis is worse than Lithuanian and improved Russian synthesis (IRS). Study of characteristics of IRS sounds shows two opposite tendencies - according to the general quantity of mistake reduction this version is tending towards the natural speech, but according to the homogeneity of mistakes, it moves away. As the first tendency is clearly dominant, the general resultant in the new version shows a tend to improve.
Correlation between intelligibility and acceptability of IRS deals possibility of small progress towards the natural speech. The IRS is more acceptable to subjects than previous version. The old synthesis is viewed as a rather decent instance of a robot's speech, while the IRS - as a poor variant of human speech.
Acceptability studies showed natural speech more enjoyed by Hungarian listeners and more critical by Italian. All versions of synthetic speech were judged as less acceptable than natural but after improvement most of listeners changed their mind
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
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
