Discussion and debate: Reflections on Pleistocene Island Occupation

Editorial Note: Within a 48-hour period during January 2014, the JMA co-editors received two papers—those of Curtis Runnels and Thomas P. Leppard printed above—that, quite fortuitously, each addressed the topic of Mediterranean island colonization by archaic hominins, albeit from radically different perspectives. Neither author was aware of the other’s paper, nor has either article subsequently been revised to take account of the other. Realizing the widespread current interest in this subject and the possibility for productive debate prompted by such variant approaches, we commissioned three sets of comments and invited Runnels and Leppard to respond. We are pleased to publish this discussion around questions of great importance for our understanding of the earliest insular prehistory of the Mediterranean, and with significant implications reaching well beyond it.

Reflections of universal algebras into semilattices, their Galois theories, and related factorization systems

Estabelecemos uma condição suficiente para a preservação dos produtos finitos, pelo reflector de uma variedade de álgebras universais numa subvariedade, que é, também, condição necessária se a subvariedade for idempotente. Esta condição é estabelecida, seguidamente, num contexto mais geral e caracteriza reflexões para as quais a propriedade de ser semi-exacta à esquerda e a propriedade, mais forte, de ter unidades estáveis, coincidem. Prova-se que reflexões simples e semi-exactas à esquerda coincidem, no contexto das variedades de álgebras universais e caracterizam-se as classes do sistema de factorização derivado da reflexão. Estabelecem-se resultados que ajudam a caracterizar morfismos de cobertura e verticais-estáveis em álgebras universais e no contexto mais geral já referido. Caracterizam-se as classes de morfismos separáveis, puramente inseparáveis e normais. O estudo dos morfismos de descida de Galois conduz a condições suficientes para que o seu par kernel seja preservado pelo reflector.

Computing, Design, Art: Reflections on an Innovative Moment in History

The paper is concerned with the role of art and design in the history and philosophy of computing. It offers insights arising from research into a period in the 1960s and 70s, particularly in the UK, when computing became more available to artists and designers, focusing on John Lansdown (1929-1999) and Bruce Archer (1922-2005) in London. Models of computing interacted with conceptualisations of art, design and related creative activities in important ways.

Teachers’ reflections on non standard students work

One of the tasks of teaching (Ball, Thames, & Phelps, 2008) concerns the work of interpreting student error and evaluating alternative algorithms used by students. Teachers’ abilities to understand nonstandard student work affects their instructional decisions, the explanations they provide in the classroom, the way they guide their students, and how they conduct mathematical discussions. However, their knowledge or their perceptions of the knowledge may not correspond to the actual level of knowledge that will support flexibility and fluency in a mathematics classroom. In this paper, we focus on Norwegian and Portuguese teachers’ reflections when trying to give sense to students’ use of nonstandard subtraction algorithms and of the mathematics imbedded in such. By discussing teachers’ mathematical knowledge associated with these situations and revealed in their reflections, we can perceive the difficulties teachers have in making sense of students’ solutions that differ from those most commonly reached.

A Taste of Research: Reflections on a Summer Vacation Research Assistantship

Research is closely intertwined in teaching and learning psychology as a science-based discipline and various methods are used to enable psychology students to grasp the nature of psychological research. VRA (Vacation Research Assistantship) schemes give students the unique opportunity to ‘taste’ what research is truly about, and develop important skills and knowledge in the process and ‘test’ their interest in a research career. VRAs provide a research-based teaching providing an experiential approach to learning, where both the student and educator are engaged as partners in the research process, reducing the role division between student and educator. This paper reflects on a VRA process and outcomes in respect of student learning and experience using as framework the teaching –research nexus (Griffiths, 2004). Both student’s and educator’s reflections are discussed as well as directions for future developments and research.

Political Discourse Analysis, Sport and Scottish Independence: Provisional Reflections upon Fairclough and Fairclough's (2012) Analytical Framework.

This paper aims to reflect upon the potential analytical utility of the political discourse analysis framework proposed by Isabela Fairclough and Norman Fairclough (2012). This framework represents the most recent substantive development upon Norman Fairclough's past work situated within the wider school of Critical Discourse Analysis, building upon his influential position this methodological tradition. Central to this development is the additional emphasis placed upon the necessity to conceptualise all political discourse as 'argumentative' in nature, given that political actors are ultimately proposing or refuting particular courses of concrete future action. This paper will therefore apply Fairclough and Fairclough's model to provisional data derived from an ongoing doctoral thesis which considers the nature of political discourse relating to sport, the Glasgow 2014 Commonwealth Games and Scottish independence, with an ultimate aim of critically considering the benefits and limitations of applying this analytical framework as a methodological tool within this ongoing study.
