A generalization of some Huang--Johnson semifields
No full textIn [H. Huang, N.L. Johnson: Semifield planes of order 82, Discrete Math., 80 (1990)], the authors exhibited seven sporadic semifields of order 26, with left nucleus F2 3 and center F2. Following the notation of that paper, these examples are referred as the Huang-Johnson semifields of type II, III, IV, V, V I, V II and V III. In [N. L. Johnson, V. Jha, M. Biliotti: Handbook of Finite Translation Planes, Pure and Applied Mathematics, Taylor Books, 2007], the question whether these semifields are contained in larger families, rather then sporadic, is posed. In this paper, we first prove that the Huang-Johnson semifield of type V I is isotopic to a cyclic semifield, whereas those of types V II and V III belong to infinite families recently constructed in [N.L. Johnson, G. Marino, O. Polverino, R. Trombetti: Semifields of order q6 with left nucleus F q 3 and center Fq, Finite Fields Appl., 14 (2008)] and [G.L. Ebert, G. Marino, O. Polverino, R. Trombetti: Infinite families of new semifields, Combinatorica, 6 (2009)]. Then, Huang-Johnson semifields of type II and III are extended to new infinite families of semifields of order q6, existing for every prime power q
On the non-autonomous Hopf bifurcation problem : systems with rapidly varying coefficients
No full textWe consider a 2-dimensional ordinary differential equation (ODE) depending on a parameter e. If the ODE is autonomous the supercritical Andronov–Hopf bifurcation theory gives sufficient conditions for the genesis of a repeller–attractor pair, made up by a critical point and a stable limit cycle respectively. We give assumptions that enable us to reproduce the analogous phenomenon in a non-autonomous context, assuming that the coefficients of the system are subject to fast oscillations, and have very weak recurrence properties, e.g. they are almost periodic (in fact we just need that the associated base flow is uniquely ergodic). In this context the critical point is replaced by a trajectory which is a copy of the base and the limit cycle by an integral manifold. The dynamics inside the attractor becomes much richer and, if one asks for stronger recurrence assumptions, e.g. the coefficients are quasi periodic, it can be (partially) analyzed by the methods of [M. Franca, R. Johnson, V. Muñoz-Villarragut, Discrete Contin. Dyn. Syst. Ser. S 9(2016), No. 4, 1119–1148]. The problem is in fact studied as a two parameters problem: we use e to describe the size of the perturbation and 1/µ to describe the speed of oscillations, but the results allows to set e = µ
Evaluative and speaker-positioning function bundles in spoken academic English. English as a Medium of Instruction at UNIBO
No full textLexical bundles, “the most frequent recurring lexical sequences in a register” (Biber et al 1999, ch. 13) have been investigated across a range of different genres. They have been found to mark ideology in political debate (Partington & Morley 2004), while possibly register-idiosyncratic variations have been found in argumentative discourse (Miller & Johnson, 2014a, 2014b, 2009). Morley (2004) and Murphy and Morley (2006) examine their discourse-marking function of introducing the writer’s evaluation in newspaper editorials, also with the aid of patterns of metaphors in newspaper editorials and news reports.
In the field of academic English, mastery of lexical bundles has been recognised as essential for fluent speech (Hyland 2012). The frequency of certain lexical bundles has been compared in different genres and registers (conversation and academic prose: Biber & Conrad 1999), while Biber et al (2004) and Biber and Barbieri (2007) have compared them in university spoken and written registers, and DeCarrico and Nattinger (1988, 1992) and Nesi and Basturkmen (2006) have focussed on lexical bundles in spoken academic registers among native speakers of English.
Following Miller and Johnson’s investigations of lexical bundles such as we must, it is time and it is + ADJ (2014a, 2014b, 2009) in argumentative discourse typical of parliamentary proceedings, where some register-idiosyncratic variation emerged, this paper aims to investigate other evaluative and speaker-positioning function bundles (Halliday 1985). Instead of parliamentary discourse, however, the present study focuses on the spoken Academic English of non-native English-speaking Italian native lecturers during lectures at an Italian University. While both academic genres, lectures and office hours are different on a level of interaction, with interaction being an inherent characteristic of the latter, while the former, particularly in the Italian academic context, still tends to be monologic with little space for participation from students. Lecturer discourse in the two genres is scrutinised in relation to the function bundles used, particularly those indicating the stance towards or opinion of the speaker towards a particular proposition, for example the likelihood of it taking place, its importance, or its necessity (Biber et al. 2004, Biber & Barbieri 2007), and occurring in the phraseology It v-link ADJ (+ that/to...).
Selected lectures and office hours from the macro-areas of Physical Sciences and Social Sciences were recorded and transcribed to form the EmiBO corpus (Johnson & Picciuolo 2022) of nearly 240,000 words. A comparative corpus investigation was performed using SketchEngine (Kilgarriff et al. 2004) to compare frequent phraseology across macro-areas and genres. The aim of this study is to reveal patterns in usage of this particular phraseology across macro disciplinary area (Physical Sciences compared with Social Sciences subjects), and subgenre (lecture vs office hour sessions).
The most frequent adjective in this phrase in argumentative discourse in Miller and Johnson (2009) was important and its synonyms. Investigation will show whether the same holds true for the academic context, in particular as regards production by non native speakers. Groom’s (2005) semantic divisions for categorising the evaluators are used. My hypothesis is that this phrase, an example of ‘explicit’ stance marking, is mainly used to further the informational content of the lecture, signalling the lecturer’s opinion of the importance or relevance of the information to follow.
Appropriate use of lexical bundles is an essential component of fluent spoken and written academic production, making it possible to distinguish between the novice and expert user (Nesi & Basturkmen 2006; Hyland 2012). This is particularly relevant in the Italian university context, where English as a Medium of Instruction is a fairly recent phenomenon and many Italian lecturers do not have a high level of English language proficiency (Campagna & Pulcini 2014: 180). While competent English language speakers have a greater reserve of options to draw on, including both implicit and explicit markers (Deroey 2018), less confident speakers might tend to overuse or misuse this phrase. In order to investigate this, corpus findings were tested against a corpus of academic spoken English produced by native speaking lecturers (BASE).

Reassessing the Johnson Presidency
No full textThe purpose of this thesis is to show that a hegemonic discourse has developed through the literature based on Lyndon Baines Johnson. This thesis also serves to challenge the discourse that has developed through the use of Archival research in order to gain a more informed understanding of the legacy of LBJ. To test this hypothesis, the existing literature has been examined and organised into primary and secondary(those who knew Johnson and those who did not)this allows us to establish if a discourse has developed, how it has developed and how it affects our perception of the Johnson Presidency. Secondly, Archival sources and data are used to challenge the hegemonic discourse that has developed. It is apparent that by conducting this research, the hegemonic discourse is mainly developed and perpetuated through secondary literature. When looking at the archival sources, it is apparent that this discourse is underdeveloped and omits key features of the Johnson Presidency that could drastically alter our perception of his time in office and ultimately his legacy as a President of the United States
