A construction of a skewaffine structure in Laguerre geometry

J. Andre constructed a skewaffine structure as a group space of a normally transitive group. In the paper this construction was used to describe such an external structure associated with a point of Laguerre plane. Necessary conditions for ensure that the external structure is a skewaffine plane are given.Comment: 10

Free cyclic submodules in the context of the projective line

We discuss the free cyclic submodules over an associative ring $R$ with unity. Special attention is paid to those, which are generated by outliers. This paper describes all orbits of such submodules in the ring of lower triangular $3$x$3$ matrices over a field $F$ under the action of the general linear group. Besides rings with outliers generating free cyclic submodules, there are also rings with outliers generating only torsion cyclic submodules and without any outliers. We give examples of all cases

Non-Standard and Minority Varieties as Community Languages in the UK: Towards a New Strategy for Language Maintenance

Supplementary schools (also referred to as complementary or Saturday schools) play a key role in teaching community heritage languages. In this way they contribute to strengthening awareness of cultural identity and confidence among pupils of migrant and minority backgrounds. The diaspora setting poses a number of challenges: parents and pupils expect supplementary schools to provide instruction in formal aspects of the heritage languages (reading and writing, and ‘correct’ grammar), but also to help develop competence in using the language in everyday settings, not least in order to enable intergenerational communication. Where the formal language differs from non-standard speech varieties (such as regional dialects), gaps may emerge between expectations and delivery. Most schools do not equip teachers to address such issues because the traditional curricula (including textbooks and teacher training packages that are often imported from the origin countries) fail to take them into consideration. The paper draws on recent research by specialist sociolinguists working in various UK settings and on a discussion among researchers and practitioners that was hosted by the University of Westminster in April 2019, co-organised by the Multilingual Manchester research unit at the University of Manchester as part of the Multilingual Communities strand of the AHRC Open World Research Initiative consortium ‘Cross- Language Dynamics: Re-shaping Communities.’ Research has shown that teachers, parents and pupils attribute importance to the teaching of standard languages, not least as a way of gaining additional formal qualifications and increasing prospects of university admission and employment. However, pupils also show an interest in everyday speech varieties and often challenge the prevailing language ideologies that fail to recognise their importance in informal communication. Teachers tend to be aware of this tension but lack the training and resources to address it in the classroom. The workshop findings suggest that failure to take non-standard speech varieties into consideration can discourage pupils from attending supplementary schools and so it also risks having an adverse effect on the transmission of standard heritage languages. Pupils’ motivation can be boosted if they are offered more tools and opportunities to communicate in everyday speech varieties. To that end, non-standard varieties must be valorised and teachers should be equipped with the skills to address language variation and pupils’ multilingual repertoires and to promote them as valuable communicative resources. The paper recommends that supplementary schools should explore ways to take into account pupils’ multilingualism and use of non-standard varieties. Curricula should be adjusted to recognise non- standard varieties as valuable resources while continuing to teach the formal (standard) varieties. Teacher training modules should be designed that take pupils’ multilingual repertoires into account and equip teachers to understand and address sociolinguistic issues such as structural variation, multilingualism and language ideologies. The paper also recommends public engagement to address the inequality that underpins the use of the terms ‘community’ versus ‘modern languages’, and calls for collaboration between mainstream (statutory) schools and supplementary schools when it comes to celebrating diversity in their pupils’ backgrounds. Academics should play a greater role in providing advice, support and training to practitioners. They should work with practitioners and stakeholders to raise public awareness of the contribution that supplementary schools make and to develop policies and pedagogical approaches to support them

Metallographic holding fixture permits polishing of soft metals on vibratory lapping machine

Circular fixture which mounts several specimens within a single turret prevents specimen smearing during grinding and polishing operations performed on a vibratory lapping machine. Each specimen is loaded individually with a weight small enough to prevent smearing but large enough to promote polishing

Designing an Affordable Health Care Program for Hispanic Immigrants in New York City

Grameen Research partnered with its sister organization Grameen America, a nonprofit microlender, and Iora Health, a Cambridge, Massachusetts-based primary health care provider, to launch a member-financed affordable health care program for low-income Hispanic immigrant women entrepreneurs in New York City.The project was intended to leverage the group support structure of Grameen programs and ultimately build a model for replication as Grameen America expands its presence in immigrant communities across the United States

Geometry of free cyclic submodules over ternions

Given the algebra $T$ of ternions (upper triangular $2\times 2$ matrices) over a commutative field $F$ we consider as set of points of a projective line over $T$ the set of all free cyclic submodules of $T^2$. This set of points can be represented as a set of planes in the projective space over $F^6$. We exhibit this model, its adjacency relation, and its automorphic collineations. Despite the fact that $T$ admits an $F$-linear antiautomorphism, the plane model of our projective line does not admit any duality.Comment: This work was carried out within the framework of the Scientific and Technological Cooperation Poland-Austria 2010--201

Why plans for a European Roma Institute might be a setback for Europe’s Roma

The Council of Europe has announced a joint-initiative with the Open Society Foundations (OSF) to establish a European Roma Institute (ERI). Yaron Matras writes that there is a danger the ERI could have negative consequences for academic freedom in the area of Romani studies. He argues that as the endeavour is guided by the philosophy that self-ascribed ancestry should override formal qualifications, the ERI could end up marginalising the study of Romani culture rather than affording it the respect and rigour that it deserves
