title: Country-of-origin effects on Russian wine consumers

authors: Cicia, Gianni

subjects: Russian wine market

abstract: In recent years, Russia has experienced significant economic growth. The wine industry is among those most affected by increases in disposable income. As a consequence, Russian wine importers have widened the range at the upper end of the quality spectrum. In the current scenario, some key questions arise concerning consumer attitudes toward wine and the way it is perceived in this evolving market. This article attempts to investigate such concerns through a choice experiment approach conducted by means of a questionnaire-based survey submitted to 388 Russian households located in the country's three largest cities (Moscow, Saint Petersburg, and Novosibirsk). In the experiment, respondents were asked to choose their favorite wine among seven dry red wines. The stated choices are analyzed using a random utility model to obtain an estimation of the price effect through a triangular distribution. Our results indicate the presence of three distinct market segments in the Russian wine market: a segment with only high-quality, highly priced Italian and French wines, a medium-quality segment currently limited to Spanish wines, and a much lower quality segment of wines in which demand for alcohol is essentially satisfied.

title: The development of Holte's 1R Classifier

authors: Nevill-Manning, Craig G.

subjects: computer science

abstract: The 1R procedure for machine learning is a very simple one that proves surprisingly effective on the standard datasets commonly used for evaluation. This paper describes the method and discusses two areas that can be improved: the way that intervals are formed when discretizing continuously-valued attributes, and the way that missing values are treated. Then we show how the algorithm can be extended to avoid a problem endemic to most practical machine learning algorithms—their frequent dismissal of an attribute as irrelevant when in fact it is highly relevant when combined with other attributes.

title: Typographic design in Māori-English bilingual picturebooks: some educational implications

authors: Vanderschantz, Nicholas

subjects: Te Reo Māori

abstract: The role of bilingual picturebooks in language learning has been explored recently by a number of authors who show their potential in normalising multilingualism (Naqvi, Thorne, Pfitscher, Nordstokke & McKeough, 2013; Zaidi, 2020), raising metalinguistic awareness and engaging parents (Sneddon, 2009), as well as raising language awareness (Kleker, Short & Daly, 2021). Hadaway and Young (2013) suggest bilingual picturebooks have a particular role to play in supporting the revitalisation of Indigenous languages. In New Zealand, the number of MāoriEnglish bilingual picturebooks is increasing, but there is very little, if any, research concerning their design or their use in educational settings. The design of bilingual picturebooks, as reflected in their linguistic landscape, has an important role to play in their pedagogical use (Daly, 2016; 2017), and in this article, we explore the typographic design of five bilingual Māori-English picturebooks with respect to the elements of typeface, type size, type colour and page layout. We discuss the design and audience implications of these factors for educational settings.
