Dros y deng mlynedd diwethaf, mae ‘astudiaethau cynhyrchu cyfryngau’ wedi tyfu’n sylweddol fel is-ddisgyblaeth. Yn sgil hyn, mae’r drafodaeth arferol ar y ddynameg rhwng technoleg, economi, ffurfiau diwylliannol, creadigrwydd a gyrfaoedd proffesiynol wedi eu trawsnewid, gan herio hen begynau disgyrsiol economi gwleidyddol ac astudiaethau diwylliannol. Er hynny, mae gogwydd cyfoes i’r datblygiadau hyn, sy’n aml yn anwybyddu hanes y cyfryngau. Mae’r erthygl hon yn ceisio defnyddio agwedd ‘astudiaethau cynhyrchu cyfryngau’ (wrth ddefnyddio fframweithiau cysyniadol Simon Cottle, Pierre Bourdieu ac Eric Berne) er mwyn olrhain hanes un o brif gwmnïau teledu Cymru, Teliesyn.

This article is based upon the idea of designing a laser that can emit light at two different wavelengths, at the same time. This kind of laser has already been produced in the past; however, the difference between the two wavelengths was much larger. We intend to reduce this difference, while still being able to emit at two different wavelengths. This article will also address the effects of linewidth broadening where it is important to know how close the two wavelengths can be before we only see one broad peak in the spectrum, rather than two individual narrow peaks. Doing this will allow us to generate terahertz radiation from just one laser source.

The rules determining the forms of nouns and adjectives after numerals and the associated initial-consonant mutations in Middle Welsh are often puzzling to Modern Welsh readers of the language. This article sketches the rules and provides a synchronic account of them. It is shown that they are based on a coherent system where number (singular, dual, numerative, plural) is central. The linguistic changes that have occurred since then are documented in detail and dated using textual evidence. It is argued that these changes can best be understood as steps along a pathway towards a new, equally coherent system where all numeral phrases are treated as singular, and gender rather than number determines both form and mutations.

Mae'r ddogfen fer hon gan Dr Hywel Griffiths yn cynnig cyflwyniad cryno i ddatblygu sgiliau trin a thrafod a chyflwyno data ystadegol o fewn Excel, ac yn addas ar gyfer myfyrwyr yn ystod tymor cyntaf eu hastudiaeth israddedig pan efallai y bydd gofyn iddynt ddefnyddio Excel am y tro cyntaf, cyn ei ddefnyddio er mwyn gwneud dadansoddiadau mwy manwl. Sgiliau TG sylfaenol yw ffocws y ddogfen felly, a'r gobaith yw y gall fod yn sail ar gyfer tasg fer mewn seminar neu diwtorial. Ar ddiwedd y ddogfen, nodir rhai cwestiynau a phwyntiau trafod y gellir ymhelaethu arnyn nhw yn y sesiynau hyn. Cliciwch ar 'Cyfryngau Cysylltiedig' i lawrlwytho'r data . Mae gallu trin data ystadegol yn sgil greiddiol o fewn y gwyddorau amgylcheddol, boed hynny ym maes daearyddiaeth ffisegol, daearyddiaeth dynol neu wyddor amgylcheddol. Defnyddir ystod o ddulliau casglu, cyflwyno a dadansoddi data ystadegol mewn ymchwil academaidd a gan gyrff ac asiantaethau sydd yn rheoli'r amgylchedd yng Nghymru. Mae sawl meddalwedd ar gael er mwyn trin a thrafod data, ac mae rhai yn fwy defnyddiol ar gyfer gwahanol bwrpasau (arddangos, dadansoddi ac ati). Un o'r rhai mwyaf cyffredin yw MS Excel.  

Cyflwyniad pwerbwynt ar thema Deddfwriaeth iaith: cyfleoedd i gyfieithwyr a gyflwynwyd gan Meinir Jones o swyddfa Comisiynydd y Gymraeg, yn ystod Cynhadledd Heriau Cyfieithu Heddiw a gynhaliwyd ym Mhrifysgol Aberystwyth ar 27 Hydref 2017.

This paper offers a brief examination of the approach taken by the Welsh Language Board, as the principal language policy and planning body in Wales, to aspects of prestige planning and the Welsh language. It describes how devolution, and the recent, first ever, national review by the Welsh Assembly Government of Welsh language policy, provide the immediate context for the work of the Welsh Language Board. The key policy document resulting from that review, Iaith Pawb, is critically analysed and the relationship to it of prestige planning is identified. The Welsh Language Board’s practice of prestige planning is discussed in relation to the discourses of neo-liberalism and post-colonialism in a way that highlights the Board’s focus on consumers rather than citizens.

In this article, we determine and analyse possible solutions to the problem of partitioning a circular cylinder into three regions of equal volume using the least surface area. The solutions are related to the minimal energy arrangement of films in dry aqueous foam confined in a cylinder. We enumerate the possible solutions and use the numerical simulation software Surface Evolver to calculate the area in each case. We determine the least area configuration for all values of the aspect ratio of the cylinder. We find only four possible optimal solutions, each appropriate over different intervals of the aspect ratio, and give closed form expressions for each one.

With the publication of its Welsh-medium Education Strategy in April 2010, the Welsh Assembly Government recognised the leading role of Welsh-medium education in the field of bilingual education throughout Europe and the world during the last fifty years. As the system further develops with increasing numbers of pupils choosing bilingual education in Wales, it is emphasised that it is important to be aware of the patterns and models available in other bilingual communities that successfully integrate bilingualism or multilingualism into their provision so that we can understand their relevance to our particular situation in Wales. This article gives an overview of the most recent developments in bilingual education in an international context and considers the important issues that emerge as this type of education continues to develop to cater for the needs of pupils in bilingual and multilingual communities throughout the world in the twenty-first century.

This article outlines the valuable contribution made by Annie Ellis (neé Davies) to the folksong revival in Wales and in particular her influence in the Aberystwyth/Cardiganshire district during the early decades of the Twentieth Century. It draws on original correspondence, fieldwork diaries, notated transcriptions, newspaper articles (in Welsh and French) and phonograph recordings from the National Library of Wales, the British Library, Bibliotèque Nationale de France and private collections. The following areas are discussed: Annie Ellis’s involvement in folksong related activities at the University of Wales, Aberystwyth, including the establishing of the Canorion Society, folksong collecting competitions and performances of J. Lloyd Williams’s operetta, Aelwyd Angharad (Angharad’s Hearth). Six historically significant concerts of traditional Welsh music given by a quartet of undergraduate singers in Paris during March 1911, including performances at Le Lied en Tout Pays and the Richelieu Amphitheatre (Sorbonne). This visit represented the embodiment of the Entente Cordiale established between Britain and France during the years leading up to the First World War. Association with Madame Lucie Barbier (head of vocal studies at the University) and the positive response of the Parisian press. Ruth Lewis and Annie Ellis’s three day fieldwork visit to Landyssul, Pencader and the surrounding district in June 1913 and the outcome of their folk song collecting, including an evaluation of the texts and melodies collected. The article also highlights the role of one Edwardian woman in developing the cultural life of Wales and her attempts to promote Welsh traditional music on an international platform.
