Single element optical systems are nowadays used very seldom due their limited optical properties. Possible solution can be the use of the variable optical components. Without need of movable mechanical parts and currently keeping small dimensions it’s possible to get optical systems with variable focal length in wide range with just one optical element. In this article there are described at this time the most often used designs of these lenses. Furthermore there is also a theoretical optical analysis for selected focal lengths of Varioptic Arctic 314 and Varioptic 416 liquid lenses included. and Jednoprvkové optické systémy jsou v současné době používány velice zřídka, a to z důvodu jejich omezených optických vlastností. Jedno z možných řešení tohoto problému může být použití optických prvků s proměnnými optickými vlastnostmi. Tyto nám umožní konstrukci optických systémů s proměnnou ohniskovou vzdáleností v širokém rozsahu bez potřeby užití pohyblivých prvků a při zachování kompaktních rozměrů. V článku jsou popsány v současné době nejvíce používaná konstrukční řešení těchto čoček. Dále je také provedena analýza vybraných optických vlastností kapalinových čoček Varioptic Arctic 314 a Varioptic Arctic 416 pro některé hodnoty z výrobcem udávaného rozsahu ohniskových vzdáleností.
Transcripts of longitudinal audio recordings of 7 Czech typical monolingual children between 1;7 to 3;9. Files are in plain text with UTF-8 encoding. Each file represents one recording session of one of the target children and is named with the presudonym of the child and her age at the given session in form YMMDD. Transcription rules and other details are to find on the homepage coczefla.ff.cuni.cz.
A new version of the previously published corpus Chroma. The version 2023.04 includes six children. Two transcripts (Julie20221, Klara30424) were removed since they did not meet the criteria on the dialogical format. The transcripts were revised (eliminating typing errors and inconsistencies in the transcription format) and morphologically annotated by the automatic tool MorphoDiTa. Detailed manual control of the annotation was performed on children's utterances; the annotation of adult data was not checked yet. Files are in plain text with UTF-8 encoding. Each file represents one recording session of one of the target children and is named with the alias of the child and their age at the given session in form YMMDD. Transcription rules and other details can be found on the homepage coczefla.ff.cuni.cz.
A new version of the previously published corpus Chroma wih morphological annotation. The version 2023.07 differs from 2023.04 in that it includes all seven children and it went through an additional careful check of consistency and conformity to the CHAT transcription principles.
Two transcripts (Julie20221, Klara30424) from the previous versions (2022.07, 2019.07) were removed since they did not meet our criteria on dialogical format. All transcripts of recordings made during one day were split into one file. Thus, version 2023.07 consists of 183 files/transcripts. The number of utterances and tokens given here in LINDAT corresponds to children's lines only.
Files are in plain text with UTF-8 encoding. Each file represents one recording session of one of the target children and is named with the alias of the child and their age at the given session in form YMMDD. Transcription rules and other details can be found on the homepage coczefla.ff.cuni.cz.
In what way do gender-specific interventions aimed at marginalised men reproduce and transform masculinities, and what kind of masculinity do social professionals, who carry out these projects, work with? This paper analyses how visual materials, spaces and artefacts enable professionals to deal with masculinity and gender-equality issues when working with men whom they assume hold traditional views on masculinity and gender roles. A three-year study of semi-public interventions that worked on individual empowerment, participation and gender equality with marginalised men in the Netherlands revealed that the professionals found it difficult to raise gender-equality issues. In contrast to the other project goals of individual empowerment and participation, gender-equality issues created a discomfort. The authors also discovered that gender equality in most cases was dealt with in more subtle ways than the issues of individual empowerment and participation. In this context, professionals worked with an ideal version of what the ‘new’ masculinity of the participants would look like, which we labelled ‘pacified masculinity’. The paper empirically shows how social professionals benefit from the use of space, images and artefacts to break down rigid gender roles and potentially enable men to construct other versions of masculine identity. Moreover, we argue that visuals and materiality create room for a reflection on the role of men in women’s emancipation., Iris van Huis, Marleen van der Haar., and Obsahuje bibliografii
