A Practical Approach to ESP – Teaching Legal English in a University Setting
No full textThis book provides some practical use to teachers approaching a new English for Specific Purposes (ESP) course with some degrees of apprehension. It attempts to discuss the influencing developments on and of ESP over the last 40 years as well as to to set the scene in the twenty-first century for ESP as seen today. It has been written with the intention that teachers will like certain parts, find useful points and maybe use ideas in some of their own lessons. The philosophy chosen by the author is the student at the very centre of the learning process, A discussion of important distinctions includes: the similarities and differences of ESP to GE, the role of the teacher, the concept of materials and learning factors, the importance of skills, syllabus and course design, and the notions of assessment and evaluation. The book has been written as teacher friendly as possible, offering practical tips and ideas, hoping to assure and be supportive to teachers entering the Brave New World of ESP
An Interference-Tolerant Algorithm for Wide-Band Moving Source Passive Localization
No full textA new technique for locating a moving source radiating a wide-band almost-cyclostationary signal is proposed. For this purpose, the signals received on two possibly moving sensors are modeled as jointly spectrally correlated, a new nonstationarity model that allows one to describe the Doppler effect accounting for a time-scale or time-stretch factor in the complex envelopes of the received signals. The proposed approach relaxes the narrow-band condition constraint under which the Doppler effect is modeled just as a frequency-shift of the carrier. The typical interference-tolerance property of cyclostationarity-based algorithms is shown to be valid under mild conditions also for (jointly) spectrally correlated signals. With respect to classical source location methods, removing the constraint of the narrow-band condition allows the adoption of larger signal bandwidths and data-record lengths, lower signal-to-noise and signal-to-interference ratios, and the capability to operate in scenarios with higher mobility. The new source location method, dubbed wide-band spectral coherence alignment (WB-SPECCOA), is exploited in a location problem involving low Earth orbit satellites
Erratum: Cyclic statistic estimators with uncertain cycle frequencies (IEEE Transactions on Information Theory (2017) 63:1 (649-675) DOI: 10.1109/TIT.2016.2614321)
No full textIN the above article [1], expression (A128), in the proof of Theorem 17 on page 672, has a missed term. Here, the missed term is considered and its convergence to zero is proved. The (conjugate) cyclic correlogram R(T)x (α, τ) is nonzero only for τ ∈ [-T,T]. Thus, from (42b) and (43), we have the following corrected version of (A128) (normalized bias of the frequency-smoothed (conjugate) cyclic periodogram with estimated (conjugate) cycle frequency) {equation presented} where {equation presented} The term B1 is considered in (A128), but for the integration interval which is R in (A128) while it is (-T,T) in (C6). The convergence to zero of B1 can be proved observing that {equation presented} with V (T)(α(T), τ) defined in [1, Eq. (39)], and using the arguments of [1] (see (A129)-(A133)). The term B2 is missed in (A128). Its convergence to zero is proved here. The first-order Taylor series expansion of q(Δf τ) for τ ∈ [-T,T] is {equation presented} where q (t) is the first-order derivative of q(t) and τ depends on τ, Δf, and T, and is such that τ Δ (0, τ) if τ > 0 and τ Δ (τ, 0) ifτ < 0. Since q(0) = 1 [1, Assumption 2], we have {equation presented}If first T →∞ with finite Δf and then Δf → 0, the term B2 does not approach zero. Let be Δf = ΔfT = T-s with s > 0. For T →∞, we have ΔfT → 0. Moreover, T ΔfT = T 1-s. Thus, the condition T ΔfT →∞ is satisfied provided that s < 1. Therefore, the condition on s is 0 < s < 1. Assumptions 1)q (t) bounded {equation presented} A sufficient condition assuring the validity of both 2) and 3) is {equation presented} Under Assumptions 1-3, from (C6), we have {equation presented} where k1 and k2 are constants. In the right-hand side of (C7), as T →∞, the first term approaches zero provided that s > 1/3 and the second one provided that s/2 + r > 1/2. This last condition is automatically satisfied since r > 1/2 (Assumption 3). Finally, the following minor corrections are needed in [1]. In (A2), the integrand function must be multiplied by a(t/Z). In (A3), the integrand function must be multiplied by a(t1/Z) a(∗)(t2/Z). In (A4), the term in the second line must be multiplied by ||a||2∞. In (A10), terms of inequalities from 2nd to 4th must be multiplied by ||a||2∞. In (A11), 2nd and 3rd terms of inequalities must be multiplied by ||a||2∞.. (Formula Presented)
The Proudly Australian Populist: Discourse Analysis of Pauline Hanson’s Language
No full textThe resurgence of populism across the world has favoured the formation of right-wing populist parties in Australia and energised Pauline Hanson’s One Nation Party. The party has enjoyed two iterations of electoral success in the Australian federation, in the 1990s and from 2016. At present, Hanson is the leader of a party with two seats in the federal Senate and supporting the governing Liberal Party in Western Australia. At first glance, she may be seen as a typical xenophobic populist, yet her figure and her message present specific peculiarities which give her surprising popularity with Australian voters. This paper analyses a corpus of some of the most controversial speeches delivered by Pauline Hanson during her political career, in a timespan ranging from 1996 to 2019. A Critical Discourse Analysis framework is employed to uncover the ideological discourse construed by the populist leader. She portrays herself as an ordinary Australian who acts in the name of the people and gives voice to the people. Her discourse entails the populist division between “the pure people” and “the corrupt elite,” imbued with racism, particularly towards Australia’s Indigenous population and a State perceived as favouring it, but also towards the Asian and Islamic communities
Image Repair or Self-Destruction? A Genre and Corpus-Assisted Discourse Analysis of Restaurants’ Responses to Online Complaints.
No full textCustomers are today becoming more and more reliant on online reviews before making their buying decisions. TripAdvisor platform, in particular, has become a first stop for holiday planning. User-generated contents have acquired the huge power to influence companies’ popularity and thence their economic performance. Firms cannot generally get negative comments removed, but TripAdvisor grants owners the opportunity to publish a reply. Complaint response represents a critical part of a business’ customer relationship management. The present study called into question the way restaurants exploit such medium, by investigating management replies to negative comments in the UK (tripadvisor.co.uk) and Italy (tripadvisor.it). The paper considered a corpus of low score reviews left on the website about properties situated in the capitals of the two countries. Genre and corpus-assisted discourse analysis were applied to examine the owners’ attitudes toward criticism in the two different cultural contexts. The research focused on the rhetorical moves and the language exploited by management to try to defend reputation by rebuilding trust or, instead, by imposing the firm’s contrasting point of view. The study revealed that British restaurants tend to use impersonal, polite and professional responses to criticism, while Italian owners often show an improvised, direct, emotional—and even angry—management of negative comments
"Bag for Good? A CDA of News Media and Popular Discourse on Lightweight Plastic Bags Ban in Australia" In Engberg, Jan / Palusci, Oriana (eds), Environmental Conflicts and Legal Disputes Across Media Discourse
No full textPlastic has transformed our lives but also generated major environmental impacts, persisting in landfill and harming marine wildlife. More and more countries in the world have thus decided to reduce unnecessary plastic usage, especially by phasing out single-use plastic bags. In Australia, most state governments have banned or pledged to ban lightweight plastic bags and the two major retailers, Coles and Woolworths, also announced plans to phase out single-use shopping bags. Nevertheless the chains encountered the customers’ rebellion against the end of the free bag era. Subsequently, Coles decided to surrender to a slower transition to reusable bags by continuing to provide free plastic bags in its stores. This decision, in turn, caused further protests by environmental movements. News media play a central role in offering access to information and shaping public opinion about environmental issues. The evolution of the Internet has significantly affected media discourse. The one-way flow of information from the newspaper to its audience has today given way to interactive news websites. Consumers have reached the active and more powerful role of text producers, as they can now publicly express their comments to online news. The participatory character of the Internet has thus allowed readers both to communicate with dominant media texts and to contribute to shape the readership’s positions. The present paper investigates the recontextualisation of the environmental legal issue of single-use plastic bags ban in news media and user-generated discourse. The study analyses a collection of articles published by the major Australian online news outlets over a two-year period and the comments they generated. The corpus-based critical discourse analysis aims at identifying the way actors and facts are framed in news discourse and user comments. Moreover, considering the high relevance of the issue in the common citizens’ life, the investigation examines the linguistic means used by readers to express distance or proximity towards the newspaper’s views and to support environmentalist or consumerist views
