Automatic rule induction in Arabic to English machine translation framework

This chapter addresses the exploitation of a supervised machine learning technique to automatically induce Arabic-to-English transfer rules from chunks of parallel aligned linguistic resources. The induced structural transfer rules encode the linguistic translation knowledge for converting an Arabic syntactic structure into a target English syntactic structure. These rules are going to be an integral part of an Arabic-English transfer-based machine translation. Nevertheless, a novel morphological rule induction method is employed for learning Arabic morphological rules that are applied in our Arabic morphological analyzer. To demonstrate the capability of the automated rule induction technique, we conducted rule-based translation experiments that use induced rules from a relatively small data set. The translation quality of the hybrid translation experiments achieved good results in terms of WER.

Request mitigating devices in Australian English and Iraqi Arabic : a comparative study

Speech acts realization in everyday interaction is seen as an important field to explore the impact of linguistic and cultural variations on cross-cultural communication and second language acquisition. The reported study investigates the use of request mitigating devices in Australian English and Iraqi Arabic. It explores the internal and external devices that speakers of the two languages use to mitigate the imposition force of requests and the impact of the linguistic and cultural parameters on this use. Request samples were collected from 14 native speakers of Australian English and 14 native speakers of Iraqi Arabic by means of eight role-play interviews. The mitigating devices were identified and classified according to a modified categorization scheme based on Blum-Kulka et al. (1989). Additional categories of mitigating devices were added to this scheme to meet the requirements of data analysis. These include consultative device (Blum-Kulka & Olshtain, 1984), questions (Trosborg, 1995), apology (Economidou-Kogetsidis, 2008), alerter (Schauer, 2007), closing (Al-Ali & Alawneh, 2010), and new categories: wish/hope statement and verbal incentive. The results showed that internal mitigating devices were more frequent in Australian English requests than in Iraqi Arabic requests, while external mitigating devices were equally pervasive in both groups. The two groups also used different semantic formulae of some mitigating devices in specific situations. The pervasive occurrence of external mitigators in both groups‟ requests is discussed in terms of volubility as a politeness strategy. It is suggested that the divergence between the two groups in their utilization of request mitigations is related to linguistic and cultural variations between the Australian and Iraqi languages and cultures.

Request mitigating devices in Australian English and Iraqi Arabic : a comparative study

Significant issues, especially miscommunication in a cross-cultural setting and pragmatic failure in second language (L2) acquisition, stem from the linguistic and cultural differences between social groups. The investigation of speech acts realization in everyday situations is deemed as an important field to explore the impact of linguistic and cultural variations on cross-cultural communication and L2 acquisition. This paper examines the internal and external mitigating devices that Australian English native speakers (AENSs) and Iraqi Arabic native speakers (IANSs) use to soften the force of request speech acts in everyday situations. It aims to explore request mitigating devices employed in Australian English and Iraqi Arabic in terms of semantic formulae and frequencies in everyday interaction. Request samples were collected from native speakers of Australian English and Iraqi Arabic by means of role-play interviews. The mitigating devices found in requests were identified and classified. The results showed that internal mitigating devices were more frequent in AENSs’ requests than in IANSs’ requests, while external mitigating devices were pervasive in both groups. The two groups also used different semantic formulae of some mitigating devices in some situations. The pervasive occurrence of external mitigators in both groups’ requests is explained in terms of the notion of volubility as a politeness strategy. It is also suggested that the divergence between the two groups in their utilization of request mitigations is related to linguistic and cultural variations between the Australian and Iraqi cultures.

Trials and tribulations of Sla framework in designing Arabic courses for speakers of other languages

There is a consensus among language teachers and researchers that language course design is always a work in progress. This is influenced by variables such as the type of language being taught and whether the teaching of this language has been researched. Arabic is one the languages that have created aperennial debate among its teachers about the anticipated challenges pointing principally to three reasons. The first reason refers to the dichotomy that exists between MSA and Colloquial Arabic, which will have a direct impact on teaching the macro-skill of „speaking‟. The second reason deals with the complexity of MSA in terms of grammar. The final reason discusses the theoretical aspects of language teaching and learning and its implications to the design of the Arabic program. This paper discusses these problems stemming from the recent empirical pilot study of teaching Arabic for a specific purposes (ASP). The study exposes some the problems mentioned above and suggests solutions to improve the teaching of Arabic in the light of theories of SLA and language teaching and learning.

Response to Islamophobia in the Arabic Islamic discourse: a critical discourse analysis

In the aftermath of September 11, Muslim scholars made numerous attempts to explain Islamophobia from the Islamic perspective; they presented arguments that are not addressed in the Western narrative. Two texts in Arabic by the prominent Muslim preacher, Mohammad Hassan and by the Muslim orator Fadhel Sliman are analysed from a Critical Discourse Analysis (CDA) viewpoint. This analysis aims to demonstrate how language is inextricably linked with ideology. This paper demonstrates that textual strategies in the Arabic Islamic discourse and their ideological implications show distinct characteristics some of which add to the present literature on discourse. The aim of the chosen texts is to educate and create solidarity between the speakers and the audience in fighting Islamophobia. The reliance of the speakers on tactics such as quoting from the Holy Qur’ān and ḥadīth to defend Islam, and choice of words and sentence structures may instigate discussions about the persuasive power of the Arabic Islamic narrative.

Barriers and enablers to healthcare access and use among Arabic-speaking and Caucasian English-speaking patients with type 2 diabetes mellitus: a qualitative comparative study

OBJECTIVE: The objective of this study was to explore the decision-making processes and associated barriers and enablers that determine access and use of healthcare services in Arabic-speaking and English-speaking Caucasian patients with diabetes in Australia. STUDY SETTING AND DESIGN: Face-to-face semistructured individual interviews and group interviews were conducted at various healthcare settings-diabetes outpatient clinics in 2 tertiary referral hospitals, 6 primary care practices and 10 community centres in Melbourne, Australia. PARTICIPANTS: A total of 100 participants with type 2 diabetes mellitus were recruited into 2 groups: 60 Arabic-speaking and 40 English-speaking Caucasian. DATA COLLECTION: Interviews were audio-taped, translated into English when necessary, transcribed and coded thematically. Sociodemographic and clinical information was gathered using a self-completed questionnaire and medical records. PRINCIPAL FINDINGS: Only Arabic-speaking migrants intentionally delayed access to healthcare services when obvious signs of diabetes were experienced, missing opportunities to detect diabetes at an early stage. Four major barriers and enablers to healthcare access and use were identified: influence of significant other(s), unique sociocultural and religious beliefs, experiences with healthcare providers and lack of knowledge about healthcare services. Compared with Arabic-speaking migrants, English-speaking participants had no reluctance to access and use medical services when signs of ill-health appeared; their treatment-seeking behaviours were straightforward. CONCLUSIONS: Arabic-speaking migrants appear to intentionally delay access to medical services even when symptomatic. Four barriers to health services access have been identified. Tailored interventions must be developed for Arabic-speaking migrants to improve access to available health services, facilitate timely diagnosis of diabetes and ultimately to improve glycaemic control.

Complex coacervation between flaxseed protein isolate and flaxseed gum

Flaxseed protein isolate (FPI) and flaxseed gum (FG) were extracted, and the electrostatic complexation between these two biopolymers was studied as a function of pH and FPI-to-FG ratio using turbidimetric and electrophoretic mobility (zeta potential) tests. The zeta potential values of FPI, FG, and their mixtures at the FPI-to-FG ratios of 1:1, 3:1, 5:1, 10:1, 15:1 were measured over a pH range 8.0-1.5. The alteration of the secondary structure of FPI as a function of pH was studied using circular dichroism. The proportion of a-helical structure decreased, whereas both β-sheet structure and random coil structure increased with the lowering of pH from 8.0 to 3.0. The acidic pH affected the secondary structure of FPI and the unfolding of helix conformation facilitated the complexation of FPI with FG. The optimum FPI-to-FG ratio for complex coacervation was found to be 3:1. The critical pH values associated with the formation of soluble (pHc) and insoluble (pHΦ1) complexes at the optimum FPI-to-FG ratio were found to be 6.0 and 4.5, respectively. The optimum pH (pHopt) for the optimum complex coacervation was 3.1. The instability and dissolution of FPI-FG complex coacervates started (pHΦ2) at pH2.1. These findings contribute to the development of FPI-FG complex coacervates as delivery vehicles for unstable albeit valuable nutrients such as omega-3 fatty acids.

Obtenção e caracterização de extrato microencapsulado de resíduo agroindustrial de acerola

Acerola (Malpighia emarginata D.C.) is a red fruit widely cultivated in Brazil, especially in the Northeastern region. Its increasing demand is attributed to its high ascorbic acid contents. Besides ascorbic acid, widely known by its health-benefit effects, acerola is rich in anthocyanins, which contribute for the antioxidant power of the fruit. Acerola processing produces a bright-red pomace, usually discarded. The further processing of this pomace, in order to explore its antioxidant compounds, could enhance acerola market value and rentability of its processing. Both ascorbic acid and anthocyanins are highly susceptible to degradation, that can be delayed by microencapsulation, which consists on packing particles (core) in an edible matrix (wall material). This work has been made with the purpose of producing a microencapsulated acerola pomace extract, which could be used by the food industry as a functional ingredient with antioxidant and coloring properties. Antioxidant compounds were recovered by pressing the pomace diluted in a solvent (a citric acid aqueous solution), by using a central composite design, with two variables: citric acid concentration in the solvent (0-2%), and solvent: pomace mass ratio (2:1-6:1). The acerola pomace extract was then microencapsulated by spray drying. A central composite design was adopted, with three variables: inlet temperature of the spray dryer (170o-200oC), wall material: acerola solids mass ratio (2:1-5:1), and degree of maltodextrin replacement by cashew tree gum as wall material (0-100%). The cashew tree gum was used because of its similarity to arabic gum, which is regarded as the wall material by excellence. The following conditions were considered as optimal for extraction of anthocyanins and ascorbic acid: solvent/pomace ratio, 5:1, and no citric acid in the solvent. 82.47% of the anthocyanins were recovered, as well as 83.22% of the ascorbic acid. Anthocyanin and ascorbic acid retentions were favored by lower inlet temperatures, higher wall material: acerola solids mass ratio and higher maltodextrin replacement by cashew tree gum, which was presented as a promising wall material. The more adequate microencapsulation conditions, based not only on retention of antioxidant compounds but also on physical properties of the final powder, were the following: inlet temperature, 185oC; wall material: acerola solids mass ratio, 5:1, and minimum degree of maltodextrin replacement by cashew tree gum, 50%
