The effect of prior visual information on recognition of speech and sounds

To identify and categorize complex stimuli such as familiar objects or speech, the human brain integrates information that is abstracted at multiple levels from its sensory inputs. Using cross-modal priming for spoken words and sounds, this functional magnetic resonance imaging study identified 3 distinct classes of visuoauditory incongruency effects: visuoauditory incongruency effects were selective for 1) spoken words in the left superior temporal sulcus (STS), 2) environmental sounds in the left angular gyrus (AG), and 3) both words and sounds in the lateral and medial prefrontal cortices (IFS/mPFC). From a cognitive perspective, these incongruency effects suggest that prior visual information influences the neural processes underlying speech and sound recognition at multiple levels, with the STS being involved in phonological, AG in semantic, and mPFC/IFS in higher conceptual processing. In terms of neural mechanisms, effective connectivity analyses (dynamic causal modeling) suggest that these incongruency effects may emerge via greater bottom-up effects from early auditory regions to intermediate multisensory integration areas (i.e., STS and AG). This is consistent with a predictive coding perspective on hierarchical Bayesian inference in the cortex where the domain of the prediction error (phonological vs. semantic) determines its regional expression (middle temporal gyrus/STS vs. AG/intraparietal sulcus).

Fusiform activation to animals is driven by the process, not the stimulus

Previous studies have found that the lateral posterior fusiform gyri respond more robustly to pictures of animals than pictures of manmade objects and suggested that these regions encode the visual properties characteristic of animals. We suggest that such effects actually reflect processing demands arising when items with similar representations must be finely discriminated. In a positron emission tomography (PET) study of category verification with colored photographs of animals and vehicles, there was robust animal-specific activation in the lateral posterior fusiform gyri when stimuli were categorized at an intermediate level of specificity (e.g., dog or car). However, when the same photographs were categorized at a more specific level (e.g., Labrador or BMW), these regions responded equally strongly to animals and vehicles. We conclude that the lateral posterior fusiform does not encode domain-specific representations of animals or visual properties characteristic of animals. Instead, these regions are strongly activated whenever an item must be discriminated from many close visual or semantic competitors. Apparent category effects arise because, at an intermediate level of specificity, animals have more visual and semantic competitors than do artifacts.

Anterior temporal cortex and semantic memory : reconciling findings from neuropsychology and functional imaging

Studies of semantic impairment arising from brain disease suggest that the anterior temporal lobes are critical for semantic abilities in humans; yet activation of these regions is rarely reported in functional imaging studies of healthy controls performing semantic tasks. Here, we combined neuropsychological and PET functional imaging data to show that when healthy subjects identify concepts at a specific level, the regions activated correspond to the site of maximal atrophy in patients with relatively pure semantic impairment. The stimuli were color photographs of common animals or vehicles, and the task was category verification at specific (e.g., robin), intermediate (e.g., bird), or general (e.g., animal) levels. Specific, relative to general, categorization activated the antero-lateral temporal cortices bilaterally, despite matching of these experimental conditions for difficulty. Critically, in patients with atrophy in precisely these areas, the most pronounced deficit was in the retrieval of specific semantic information.

Supporting process model validation through natural language generation

The design and development of process-aware information systems is often supported by specifying requirements as business process models. Although this approach is generally accepted as an effective strategy, it remains a fundamental challenge to adequately validate these models given the diverging skill set of domain experts and system analysts. As domain experts often do not feel confident in judging the correctness and completeness of process models that system analysts create, the validation often has to regress to a discourse using natural language. In order to support such a discourse appropriately, so-called verbalization techniques have been defined for different types of conceptual models. However, there is currently no sophisticated technique available that is capable of generating natural-looking text from process models. In this paper, we address this research gap and propose a technique for generating natural language texts from business process models. A comparison with manually created process descriptions demonstrates that the generated texts are superior in terms of completeness, structure, and linguistic complexity. An evaluation with users further demonstrates that the texts are very understandable and effectively allow the reader to infer the process model semantics. Hence, the generated texts represent a useful input for process model validation.

Aligning off-balance sheet risk, on-balance sheet risk and audit fees: a PLS path modelling analysis

This study focuses on using the partial least squares (PLS) path modelling technique in archival auditing research by replicating the data and research questions from prior bank audit fee studies. PLS path modelling allows for inter-correlations among audit fee determinants by establishing latent constructs and multiple relationship paths in one simultaneous PLS path model. Endogeneity concerns about auditor choice can also be addressed with PLS path modelling. With a sample of US bank holding companies for the period 2003-2009, we examine the associations among on-balance sheet financial risks, off-balance sheet risks and audit fees, and also address the pervasive client size effect, and the effect of the self-selection of auditors. The results endorse the dominating effect of size on audit fees, both directly and indirectly via its impacts on other audit fee determinants. By simultaneously considering the self-selection of auditors, we still find audit fee premiums on Big N auditors, which is the second important factor on audit fee determination. On-balance-sheet financial risk measures in terms of capital adequacy, loan composition, earnings and asset quality performance have positive impacts on audit fees. After allowing for the positive influence of on-balance sheet financial risks and entity size on off-balance sheet risk, the off-balance sheet risk measure, SECRISK, is still positively associated with bank audit fees, both before and after the onset of the financial crisis. The consistent results from this study compared with prior literature provide supporting evidence and enhance confidence on the application of this new research technique in archival accounting studies.

Rapid on-site evaluation of fine needle aspiration specimens by cytology scientists : a review of 3032 specimens

Objectives To determine: (1) the accuracy of cytology scientists at assessing specimen adequacy by rapid on-site evaluation (ROSE) at fine needle aspiration (FNA) cytology collections; and (2) whether thyroid FNA with ROSE has lower inadequacy rates than non-attended FNAs. Methods The ROSE of adequacy for 3032 specimens from 17 anatomical sites collected over a 20-month period was compared with the final report assessment of adequacy. ROSE was performed by 19 cytology scientists. The report profile for 1545 thyroid nodules with ROSE was compared with that for 1536 consecutive non-ROSE thyroid FNAs reported by the same cytopathologists during the study period. Results ROSE was adequate in 75% (2276/3032), inadequate in 12% (366/3032) and in 13% (390/3032) no opinion was rendered. Of the 2276 cases assessed as adequate by ROSE, 2268 (99.6%) were finally reported as adequate for assessment; eight specimens had adequacy downgraded on the final report. Fifty eight per cent of cases with a ROSE assessment of inadequate were reported as adequate (212/366), whereas 93% (363/390) with no opinion rendered were reported as adequate. The overall final report adequacy rate for the 3032 specimens was 94% (2843/3032). Confirmation of a ROSE of adequacy at reporting was uniformly high amongst the 19 scientists, ranging from 98% to 100%. The inadequacy rate for thyroid FNAs with ROSE (6%) was significantly (P < 0.0001) lower than for non-ROSE thyroid FNAs (17%). A significantly (P = 0.02) higher proportion of adequate ROSE thyroid specimens was reported with abnormalities, compared with non-ROSE thyroid collections. Conclusions Cytology scientists are highly accurate at determining specimen adequacy at ROSE for a wide range of body sites. ROSE of thyroid FNAs can significantly reduce inadequate reports.

Contrast and Emphasis: An Essay on the Modal Adverb Ke in Declarative Sentences [对比与强调 --- 谈陈述句中的语气副词“可”]

The data-oriented empirical research on the Chinese adverb “ke” has led to the conclusion that the semantics of the word as a modal adverb is always two-fold: it marks both “contrast” and “emphasis”. “Adversativity” as used in literature on “ke” is but one type of contrast marked by “ke”. Other types of contrast marked by “ke” in declarative sentences include: a) what is assumed by the hearer and what the truth of a matter is; b) what the sentence literally talks about and what it also implicitly conveys; and c) the original wishful nature of the stated action and its final realization. In all declarative sentences, what the adverb emphasizes is the “factuality” of what is stated. Chinese Abstract [提要] 对外汉语教学的实践表明，汉语副词“可”是教学中的难点，这跟我们对其语义内涵缺乏全面准确的认识有关。为了全面揭示副词“可”的核心语义，本作者以电视连续剧《渴望》前二十集为主要语料，并结合其他一些电视剧、电视节目以及文献里已有的语料，对出现在各种语境中的“可”进行了大量的考察和归纳性研究。研究结果表明，作为语气副词的“可”其核心语义不是单一的，它总是在标示“对比”（即“不同”）的同时表示强调。它所强调的是所述内容的“事实性”或“终然性”。由于篇幅所限，本文仅对陈述句中的语气副词“可”加以讨论

Distant Deaths : How Newspapers Report Fatal Events from Abroad

Despite the advent of globalisation and increasing interaction between people from different cultures, many people still are influenced in their opinion about people from other countries based on what they read, see or hear in the mass media. By investigating how newspapers report about deaths in their foreign news sections, this book provides an in-depth account of the journalistic decision-making behind the portrayal of people from other countries. Although there have been a few studies that examined news coverage of foreign death to some extent, this particular study presents the first comprehensive analysis of the topic. The book examines how newspapers in Australia and Germany decide on which foreign deaths to cover and, employing an innovative framework, it finds that cultural connections play a large part in the decision-making process. Differences between the newspapers in terms of linguistic and visual coverage of fatal events can also be traced along cultural lines. The book will be useful to students of journalism, international and intercultural communication as well as anyone interested in discourses about death in the public sphere.

Work Health and Safety Regulation in Australia: the Model Act

This book critically analyses the Model Work Health and Safety Bill, which is the pivotal legal instrument upon which the harmonisation of work health and safety regulation in Australia is based. This Model Act has already been adopted from 1 January 2012 in some Australian jurisdictions – the Commonwealth, New South Wales, Queensland and the two territories – and is the culmination of a long process which gained renewed impetus with a National Review of Model Occupational Health and Safety Laws commissioned by the Federal Government on behalf of all Australian governments in April 2008. The book explains the origins of the Model Act, analyses its provisions, outlines practical issues, including potential difficulties, in their application and makes suggestions for further debate to develop the harmonised provisions. It explores the potential of the harmonised health and safety laws and assesses their adequacy to guide us through the challenges of the next century.

Teaching spelling in the middle years : reviewing programs for diverse student groups

In what follows, I draw attention to understandings about the teaching of Standard Australian English spelling developed by being immersed in the URL project site for four years though sharing professional dialogue with teachers and educators and entering into informal conversations with some of the students and their parents. My understandings focus on the potential and problematics of oft-used generic spelling programs and approaches for student cohorts marked by social, cultural and linguistic diversity. This article concludes by considering two possible extensions to the word study approach that may have utility for working with middle years students from diverse backgrounds: creating a discursive ‘Third Space’ that overtly recognises students’ language experiences and the technique of colour blocking to create a visual stress.

Prosecution of maritime pirates : the national court is dead—long live the national court

Piracy is one of the main maritime security concerns in the contemporary world. The number of piracy incidents is increasing rapidly, which is highly problematic for maritime security. Although international law provides universal jurisdiction for the prosecution of maritime pirates, the actual number of prosecutions is alarmingly low compared to the number of incidents of piracy. Despite many states becoming parties to the relevant international conventions, they are reluctant to establish the necessary legal and institutional frameworks at the national level for the prosecution of pirates. The growing incidences of piracy and the consequential problems associated with prosecuting pirates have created doubts about the adequacy of the current international legal system, which is fully dependent on national courts for the prosecution of pirates. This article examines the possible ways for ensuring the effective prosecution of pirates. Contrary to the different proposals forwarded by researchers in the wake of Somali piracy for the establishment of international judicial institutions for the prosecution of pirates, this article argues that the operationalization of national courts through the proper implementation of relevant international legal instruments within domestic legal systems is the most viable solution. However, this article submits that the operationalization of national courts will not be very successful following the altruistic model of universal adjudicative jurisdiction. A state may enact legislation implementing universal jurisdiction but will not be very interested in prosecuting a pirate in its national court if it has no relation with the piratical incident. Rather, it will be successful if the global community seriously implement the Convention for the Suppression of Unlawful Acts against the Safety of Maritime Navigation (SUA Convention), which obligates the states that have some connection with a piratical incident to prosecute pirates in their national courts.

What is the relationship between the term 'ADHD' and the object it purports to represent?

This paper addresses the question: what is the relationship between the term ADHD, and the object it purports to represent? While the most familiar linguistic position—Referential Theory— suggests that the term constitute an etymological peg corresponding to a particular part of nature, there are other, arguably more sophisticated, philosophical approaches that point to an altogether more complex relationship. These approaches do not assume that ‘behaviour disorders’, such as ADHD, are objective facts of nature, facts to which words can simply be adhered. Using the work of Wittgenstein, the intention here is to use the philosophy of language to destabilise, not just the relationship between the term ADHD and the idea to which it applies, but also the coherence of the notion of ADHD itself.

“Well, hang on, they’re actually much better than that!” : disrupting dominant discourses of deficit about English language learners in senior high school English

This paper explores how four English teachers position their English language learners for critical literacy within senior high school curriculum in Queensland, Australia. Such learners are often positioned, even by their teachers, within a broader “deficit discourse” that claims they are inherently lacking the requisite knowledge and skills to engage with intransigent school curricula. As such, English language learners’ identity formation is often constrained by deficit views that can ultimately see limited kinds of literacy teaching offered to them. Using Fairclough’s (2003) critical discourse analysis method, analysis of 16 interviews with the teachers was conducted as part of a larger, critical instrumental case study in two state high schools during 2010. Five competing discourses were identified: deficit as lack; deficit as need; learner “difference” as a resource; conceptual capacity for critical literacy; and linguistic, cultural and conceptual difficulty with critical literacy. While a deficit view is present, counter-hegemonic discourses also exist in their talk. The combination of discourses challenges monolithic deficit views of English language learners, and opens up generative discursive territory to position English language learners in ways other than “problematic”. This has important implications for how teachers view and teach English language learners and their capacity for critical literacy work in senior high school classrooms.

Scaffolding multimodal literacies: Learning in and out of the classroom

This chapter presents data produced by a research project that looked at pedagogy for print and digital literacies in a high poverty, high diversity primary school. The student population included refugee, immigrant and Aboriginal and Torres Strait Islander young people. In an environment in which schools, such as the study site, are under pressure to narrow the curriculum to ‘the basics’, the project sought to support teachers as they worked to create a rich curriculum for all students. The chapter will focus on pedagogy in an after-school media club. The aim of the club, which ran weekly for several years, was to build students’ media literacy skills. The data suggest that established ways of scaffolding linguistic texts cannot be simply transferred to multimodal text production. The chapter will also address implications from the research outcomes for other teachers working with At Risk EAL students.
