KBRE: a framework for knowledge-based requirements engineering

Detecting inconsistencies is a critical part of requirements engineering (RE) and has been a topic of interest for several decades. Domain knowledge and semantics of requirements not only play important roles in elaborating requirements but are also a crucial way to detect conflicts among them. In this paper, we present a novel knowledge-based RE framework (KBRE) in which domain knowledge and semantics of requirements are central to elaboration, structuring, and management of captured requirements. Moreover, we also show how they facilitate the identification of requirements inconsistencies and other-related problems. In our KBRE model, description logic (DL) is used as the fundamental logical system for requirements analysis and reasoning. In addition, the application of DL in the form of Manchester OWL Syntax brings simplicity to the formalization of requirements while preserving sufficient expressive power. A tool has been developed and applied to an industrial use case to validate our approach.

A Taylor Model Based Description of the proof stress of magnesium AZ31 during hot working

A series of hot-compression tests and Taylor-model simulations were carried out with the intention of developing a simple expression for the proof stress of magnesium alloy AZ31 during hot working. A crude approximation of wrought textures as a mixture of a single ideal texture component and a random background was employed. The shears carried by each deformation system were calculated using a full-constraint Taylor model for a selection of ideal orientations as well as for random textures. These shears, in combination with the measured proof stresses, were employed to estimate the critical resolved shear stresses for basal slip, prismatic slip, ⟨c+a⟩ second-order pyramidal slip, and { } twinning. The model thus established provides a semianalytical estimation of the proof stress (a one-off Taylor simulation is required) and also indicates whether or not twinning is expected. The approach is valid for temperatures between ∼150 °C and ∼450 °C, depending on the texture, strain rate, and strain path.

Description of loxocythere (novoloxocythere) pelius subgen. sp. nov. (ostracoda) from the cenozoic of S.E. Australia with comments on species of antarctiloxoconcha hartmann, 1986 and loxoreticulatum benson, 1964 from Australian and Antarctic marine waters

Loxocythere (Novoloxocythere) pelius subgen. et sp. nov. is described from Upper Miocene strata of the Port Phillip and Western Port Basins. Victoria. It has its acme in shallow open marine facies of latest Miocene (Cheltenhamian) age. This species, along with Loxocythere (Novoloxocythere) kerryswansoni Yassini and Jones, 1995, forms a discrete group of rotund Australian Loxocythere species that possess posterior extremities in both valves that are positioned well above mid carapace height (i.e. adjacent to dorsal margin). This feature along with a sub-triangular inner margin outline, defines a carapace shape that is distinct from that of rotund species of Loxocythere (loxocythere) Hornibrook, 1952 and Antarctiloxoconcha Hartmann, 1986. The type species of Antarctiloxoconcha – A.frigida (Neale. 1967), possesses internal carapace features that are very similar to the type species of Loxocythere - L. crassa Hornibrook, 1952. Both have relatively short carapaces and sub-quadrate inner margin outlines with posterior extremities in both valves positioned below mid carapace height. Species of Loxocythere (Novoloxocythere), in particular L. (N.) kerryswansoni, have a carapace shape that is transitional between Loxocythere and Loxoreticulatum Benson, 1964. Species of Loxoreticulatum generally possess a sub-parallelogram shaped carapace/inner margin and arched median hinge element. The latter feature is distinct from the mostly straight median hinge elements of Loxocythere (Loxocythere) and Loxocythere (Novoloxocythere) species. Species of Loxocythere (Novoloxocythere) are also readily distinguishable from relatively elongate species of Loxocythere, such as L. (L.) hornibrooki McKenzie, 1967, as the latter possess long (for genus), sub-rectangular shaped carapaces/inner margin outlines and posterior extremities below mid height.

Meaningful UDDI web services description

There is a lack of meaningful description of Web Services in UDDI, however, it is necessary for automatic services discovery. In this paper, a language is proposed for semantics description of Web Services which complements the UDDI standards to derive relationships among Web Services. The semantics description can be used to automatically derive relationships among Web Services. We describe how the semantics description of Web Services, based on the proposed language, can be integrated with UDDI.

Corporate ethics and trust in intra-corporate relationships, an in-depth and longitudinal case description

Theoretically, a contribution of this article is the pinpointed connection between corporate ethics and trust in intra-corporate relationships. Furthermore, it contributes to a conceptual framework that distinguishes between the constructs of business ethics and corporate ethics. The authors also provide a grounded conceptual framework of corporate ethics and trust. The principal dyadic determinants of corporate ethics in intra-corporate relationships are interpreted to be management behaviour versus employee perception of that behaviour. Empirically, the contribution is an in-depth and longitudinal case description that underpins the topic and the discussion provided in the article.

Description of new species of Setosabatieria and Desmolaimus (Nematoda: Monhysterida) and a checklist of New Zealand free-living marine nematode species

Two new marine nematode species are described from intertidal sediments in southern New Zealand. Setosabatieria australis sp. nov. is characterised by an amphideal fovea with 3.5 turns, 7–9 small pre-cloacal supplements, and 2–5 sub-cephalic setae per file. Setosabatieria australis sp. nov. differs from all known species of the genus in having L-shaped spicules with a hollow median region, in contrast to the typical curved shape. Desmolaimus courti sp. nov. is characterised by the presence of four long (15 µm) cephalic setae, two cuticularised rings in the buccal cavity, and a lightly cuticularised pharyngeal lumen. It differs from other species of the genus by having eight sub-cephalic setae. A total of 116 marine species are included in the checklist of New Zealand free-living nematodes, with the majority of records from the coast of Campbell and Auckland islands from the early part of the 20th century. Most records were from habitats such as seaweed or sponge, which may explain the high proportion (>50%) of cosmopolitan species recorded in New Zealand to date. Little is known about the sediment nematode fauna, particularly in deeper waters (>120 m), from where there are no records to date.

Priority setting in health: origins, description and application of the Australian Assessing Cost-Effectiveness initiative

This article reports on the ‘Assessing Cost–Effectiveness’ (ACE) initiative in priority setting from Australia. It commences with why priority setting is topical and notes that a wide variety of approaches are available. In assessing these various approaches, it is argued that a useful first step is to consider what constitutes an ‘ideal’ approach to priority setting. A checklist to guide priority setting is presented based on guidance from economic theory, ethics and social justice, lessons from empirical experience and the needs of decision-makers. The checklist is seen as an important contribution because it is the first time that criteria from such a broad range of considerations have been brought together to develop a framework for priority setting that endeavors to be both realistic and theoretically sound. The checklist will then be applied to a selection of existing approaches in order to illustrate their deficiencies and to provide the platform for explaining the unique features of the ACE approach. A case study (ACE-Cancer) will then be presented and assessed against the checklist, including reaction from stakeholders in the cancer field. The article concludes with an overview of the full body of ACE research completed to date, together with some reflections on the ACE experience.

Anticipating policy and logics of practice : Australian institutional and academic responses to the globalising "quality research" agenda

Research assessment is now an international trend. This article mobilises a critical policy sociology informed by Bourdieu to unpack the differential effects of research policy shifts in Australia on universities, academics and the field of educational research. It argues in anticipating policy moves - from surveying the logics of practice that have emerged elsewhere from research assessment - that institutional, individual and field responses, while specific to the Australian policy context and mix, have assumed a logic of practice counter productive to "quality" research, education as a field, and equity.

Academic pedagogies, quality logics and performative universities : evaluating teaching and what students want

Universities have focused on teaching and learning at a time when quality has become the marker of distinction in international higher education markets. Education markets have meant pedagogical relations have become contractualised with a focus on student satisfaction, exemplified in consumer-oriented generic evaluations of teaching. This article argues, by analysing one example, that generic evaluations are more about accountability and marketing than about improvement of teaching and learning. Furthermore, what students want is not the only criterion for judging teaching. Rather, professionals require, as do academics, a capacity for critical judgement about what constitutes valued knowledge in the pedagogical relationship between teacher and student.

MOSAIC (MOthers' Advocates In the Community): protocol and sample description of a cluster randomised trial of mentor mother support to reduce intimate partner violence among pregnant or recent mothers

Background : Intimate partner violence (IPV) is prevalent globally, experienced by a significant minority of women in the early childbearing years and is harmful to the mental and physical health of women and children. There are very few studies with rigorous designs which have tested the effectiveness of IPV interventions to improve the health and wellbeing of abused women. Evidence for the separate benefit to victims of social support, advocacy and non-professional mentoring suggested that a combined model may reduce the levels of violence, the associated mental health damage and may increase a woman's health, safety and connection with her children. This paper describes the development, design and implementation of a trial of mentor mother support set in primary care, including baseline characteristics of participating women.

Methods/Design : MOSAIC (MOtherS' Advocates In the Community) was a cluster randomised trial embedded in general practice and maternal and child health (MCH) nursing services in disadvantaged suburbs of Melbourne, Australia. Women who were pregnant or with infants, identified as abused or symptomatic of abuse, were referred by IPV-trained GPs and MCH nurses from 24 general practices and eight nurse teams from January 2006 to December 2007. Women in the intervention arm received up to 12 months support from trained and supported non-professional mentor mothers. Vietnamese health professionals also referred Vietnamese women to bilingual mentors in a sub-study. Baseline and follow-up surveys at 12 months measured IPV (CAS), depression (EPDS), general health (SF-36), social support (MOS-SF) and attachment to children (PSI-SF). Significant development and piloting occurred prior to trial commencement. Implementation interviews with MCH nurses, GPs and mentors assisted further refinement of the intervention. In-depth interviews with participants and mentors, and follow-up surveys of MCH nurses and GPs at trial conclusion will shed further light on MOSAIC's impact.

Discussion : Despite significant challenges, MOSAIC will make an important contribution to the need for evidence of effective partner violence interventions, the role of non-professional mentors in partner violence support services and the need for more evaluation of effective health professional training and support in caring for abused women and children among their populations.

“I would rather write a thesis than a letter”: from description to inscription in feminist pedagogical enquiry

The discourses that dominate schooling and education are complicit in, and circulate reductionist and bounded understandings of social relationships (Lather, 2004; MacLure, 2003; Atkinson, 2003a). Those deeply implicated in these  relationships understand that the pragmatic discourses of teaching and learning do little to elucidate or generate understandings about pedagogy that recognise the complex and contingent. There is a need for research that gives account of the experience of learning to teach without abetting the neoliberal accountability discourses in teacher education. This paper unfolds to the reader one practitioner researcher’s ways to come to know living pedagogy (Aoki, Low & Palulis, 2001) and research through the possibilities of epistolary in pedagogical enquiry.

When the logics of the world collapse – Žižek with and against Arendt on 'totalitarianism'

Despite Žižek's polemical attacks on Hannah Arendt, their writings on totalitarianism share significant similarities. Žižek's Lacanian analysis of the distortion of the elementary symbolic coordinates of human sociability in Stalinism refines Arendt's controversial account of the role of ideologies in totalitarian regimes; it brings to the political field an account of subjectivity and its relation to language derived from (Lacanian) psychoanalysis. Reading Žižek's analyses of Stalinist and fascist ideologies preserves – by psychoanalytically reframing – the radical philosophical register of Arendt's understanding of twentieth-century totalitarian regimes as attempting the systematic destruction of ‘world’ – the in-between public space of shared political human experience and action. Žižek's psychoanalytic framework allows us to address the tendency in Arendt's Origins of Totalitarianism to conflate fascism and Stalinism and also to question the motives for these regimes’ political and ontological violences.

Review of Alataleberis McKenzie and Warne, 1986 and description of Alatapacifica gen. nov. (Ostracoda, Crustacea) from the Cenozoic of Australasia

Species originally assigned to the pterygocytherine genus Alataleberis by McKenzie & Warne, 1986 are placed here in two genera—Alataleberis sensu stricto and Alatapacifica gen. nov. Alataleberis species possess poorly defined dorsal ridges marked by a few spines in adult specimens and lack a subcentral tubercle. Alatapacifica species possess well-developed and buttressed dorsal ridges and a well-developed subcentral tubercle. Pterygocytherine genera/species groups recognized here from the southwest Pacific region are Alataleberis, Alatapacifica (septarca and robusta species groups), Alatahermanites Whatley & Titterton, 1981 and the velivola species group of Pterygocythereis Blake, 1933.
