Embedding generic employability skills in an accounting degree: development and impediments

This paper explores and analyses the views of, and effects on, students of a project that integrated the development of employability skills within the small group classes of two compulsory courses in the first year of an accounting degree at a UK university. The project aimed to build, deliver and evaluate course materials designed to encourage the development of a broad range of employability skills: skills needed for life-long learning and a successful business career. By analysing students' opinions gathered from a series of focus groups spread throughout the year, three prominent skill areas of interest were identified: time management, modelling, and learning to learn. Further analysis highlighted the complex nature of skills development, and brought to light a range of impediments and barriers to both students' development of employability skills and their subject learning. The analysis suggests the need for accounting educators to see skills development as being an essential element of the path to providing a successful accounting education experience

Breaking from Tradition: Transforming Leadership Education in Nursing

Leadership development is critical for nurses to be engaged in health system reform and transformation. Trends in nursing practice led to the development of an innovative senior consolidation course in our four year undergraduate nursing program. We hypothesized that providing opportunities for application of theoretical knowledge related to complex adaptive systems and leadership would enhance professional identity formation. We describe our experiences implementing a clinical course wherein nursing students are provided opportunities to explore and develop their leadership acumen within an undergraduate curriculum. We discuss how breaking from curricular tradition involved intentional use of pedagogy (transformational learning theory), innovative instructional design, and the formation of collaborative partnerships to provide a space for students to practice the cognitive, relational, and meaning making skills required for leadership development. We highlight the impact of this journey on students, faculty, and community partners as we forge ahead in planning next steps to determine the level of engagement of our graduates in health system design, advocacy, and stewardship. Résumé Le développement du leadership par les infirmières est essentiel si elles veulent participer à la réforme et à la transformation du système de santé. Les tendances observées dans la pratique infirmière ont mené à l’élaboration d’un cours d’intégration en fin de programme de premier cycle de quatre années en sciences infirmières. Nous avons fait l’hypothèse qu’en offrant des occasions d’appliquer les connaissances théoriques liées aux systèmes adaptatifs complexes et au leadership, la formation de l’identité professionnelle serait renforcée. Nous décrivons ici nos expériences de la mise en œuvre d’un cours clinique où les étudiantes en sciences infirmières ont l’occasion d’explorer et de développer leur compétence de leadership dans le cadre d’un programme de premier cycle. Nous abordons en quoi le fait de s’être éloignés du programme traditionnel a pavé la voie à l’utilisation intentionnelle de la pédagogie (théorie de l’apprentissage transformationnel), à une conception pédagogique novatrice et à la formation de partenariats de collaboration afin d’offrir aux étudiantes un milieu où elles peuvent mettre en pratique les habiletés cognitives, relationnelles et de réflexion nécessaires au développement du leadership. Nous mettons en valeur l’impact de ce cheminement sur les étudiantes, le corps enseignant et les partenaires de la communauté alors que nous nous préparons à planifier les prochaines étapes pour déterminer le degré de participation de nos diplômées à la conception, à la promotion et à la gestion dans le système de santé

Using Deep Neural Networks for Speaker Diarisation

Speaker diarisation answers the question “who spoke when?” in an audio recording. The input may vary, but a system is required to output speaker labelled segments in time. Typical stages are Speech Activity Detection (SAD), speaker segmentation and speaker clustering. Early research focussed on Conversational Telephone Speech (CTS) and Broadcast News (BN) domains before the direction shifted to meetings and, more recently, broadcast media. The British Broadcasting Corporation (BBC) supplied data through the Multi-Genre Broadcast (MGB) Challenge in 2015 which showed the difficulties speaker diarisation systems have on broadcast media data. Diarisation is typically an unsupervised task which does not use auxiliary data or information to enhance a system. However, methods which do involve supplementary data have shown promise. Five semi-supervised methods are investigated which use a combination of inputs: different channel types and transcripts. The methods involve Deep Neural Networks (DNNs) for SAD, DNNs trained for channel detection, transcript alignment, and combinations of these approaches. However, the methods are only applicable when datasets contain the required inputs. Therefore, a method involving a pretrained Speaker Separation Deep Neural Network (ssDNN) is investigated which is applicable to every dataset. This technique performs speaker clustering and speaker segmentation using DNNs successfully for meeting data and with mixed results for broadcast media. The task of diarisation focuses on two aspects: accurate segments and speaker labels. The Diarisation Error Rate (DER) does not evaluate the segmentation quality as it does not measure the number of correctly detected segments. Other metrics exist, such as boundary and purity measures, but these also mask the segmentation quality. An alternative metric is presented based on the F-measure which considers the number of hypothesis segments correctly matched to reference segments. A deeper insight into the segment quality is shown through this metric

Postcolonial hybridity, diaspora and accountancy: evidence from Sierra Leonean chartered and aspiring accountants

Purpose: The purpose of this paper is to explore perceptions and lived experiences of Sierra Leonean chartered and aspiring accountants, vis-à-vis their professional identity with a particular focus on two elements of postcolonial theory, hybridity and diaspora. Design/methodology/approach: A qualitative methodological framework was employed. Semi-structured interviews were conducted with 18 participants about their perceptions of their professional identity and their professional experiences both within and outside Sierra Leone. Findings: The current professionalisation process is conceptualised as a postcolonial third space where hybrid professional accountants are constructed. Professional hybridity blurs the local/global praxis being positioned as both local and global accountants. Participants experience difficulty “fitting into” the local accountancy context as a consequence of their hybridisation. As such, a diaspora effect is induced which often culminates in emigration to advanced countries. The paper concludes that although the current model engenders emancipatory social movements for individuals through hybridity and diaspora, it is nonetheless counterproductive for Sierra Leone’s economic development and the local profession in particular. Research limitations/implications: This study has significant implications for understanding how the intervention of global professional bodies in developing countries shapes the professionalisation process as well as perceptions and lived experiences of chartered and aspiring accountants in these countries. Originality/value: While extant literature implicates the legacies of colonialism/imperialism on the institutional development of accountancy (represented by recognised professional bodies), this paper employs the critical lens of postcolonial theory to conceptualise the lived experiences of individuals who are directly impacted by such institutional arrangements

Support for graphicacy: a review of textbooks available to accounting students

This Teaching Note reports on the support available in textbooks for graphicacy that will help students understand the complexities of graphical displays. Graphical displays play a significant role in financial reporting, and studies have found evidence of measurement distortion and selection bias. To understand the complexities of graphical displays, students need a sound understanding of graphicacy and support from the textbooks available to them to develop that understanding. The Teaching Note reports on a survey that examined the textbooks available to students attending two Scottish universities. The support of critical graphicacy skills was examined in conjunction with textbook characteristics. The survey, which was not restricted to textbooks designated as required reading, examined the textbooks for content on data measurement and graphical displays. The findings highlight a lack of support for graphicacy in the textbooks selected. The study concludes that accounting educators need to scrutinize more closely the selection of textbooks and calls for more extensive research into textbooks as a pedagogic tool

Strategies to optimize the impact of nutritional surveys and epidemiological studies

The development of nutrition and health guidelines and policies requires reliable scientific information. Unfortunately, theoretical considerations and empirical evidence indicate that a large percentage of science-based claims rely on studies that fail to replicate. The session "Strategies to Optimize the Impact of Nutrition Surveys and Epidemiological Studies" focused on the elements of design, interpretation, and communication of nutritional surveys and epidemiological studies to enhance and encourage the production of reliable, objective evidence for use in developing dietary guidance for the public. The speakers called for more transparency of research, raw data, consistent data-staging techniques, and improved data analysis. New approaches to collecting data are urgently needed to increase the credibility and utility of findings from nutrition epidemiological studies. Such studies are critical for furthering our knowledge and understanding of the effects of diet on health

The helminth product, ES-62, protects against airway inflammation by resetting the Th cell phenotype

We previously demonstrated inhibition of ovalbumin (OVA)-induced allergic airway hyper-responsiveness in the mouse using ES-62, a phosphorylcholine-containing glycoprotein secreted by the filarial nematode, Acanthocheilonema viteae. This inhibition correlated with ES-62-induced mast cell desensitisation, although the degree to which this reflected direct targeting of mast cells remained unclear as suppression of the Th2 phenotype of the inflammatory response, as measured by eosinophilia and IL-4 levels in the lungs, was also observed. We now show that inhibition of the lung Th2 phenotype is reflected in ex vivo analyses of draining lymph node recall cultures and accompanied by a decrease in the serum levels of total and OVA-specific IgE. Moreover, ES-62 also suppresses the lung infiltration by neutrophils that is associated with severe asthma and is generally refractory to conventional anti-inflammatory therapies, including steroids. Protection against Th2-associated airway inflammation does not reflect induction of regulatory T cell (Treg) responses (there is no increased IL-10 or Foxp3 expression) but rather a switch in polarisation towards increased T-bet expression and IFNγ production. This ES-62-driven switch in the Th1/Th2 balance is accompanied by decreased IL-17 responses, a finding in line with reports that IFNγ and IL-17 are counter-regulatory. Consistent with ES-62 mediating its effects via IFNγ-mediated suppression of pathogenic Th2/Th17 responses, we found that neutralising anti-IFNγ antibodies blocked protection against airway inflammation in terms of pro-inflammatory cell infiltration, particularly by neutrophils and lung pathology. Collectively, these studies indicate that ES-62, or more likely small molecule analogues, could have therapeutic potential in asthma, in particular for those subtypes of patients (e.g. smokers, steroid-resistant) who are refractory to current treatments

Diversity of Matriptase Expression Level and Function in Breast Cancer

Overexpression of matriptase has been reported in a variety of human cancers and is sufficient to trigger tumor formation in mice, but the importance of matriptase in breast cancer remains unclear. We analysed matriptase expression in 16 human breast cancer cell lines and in 107 primary breast tumors. The data revealed considerable diversity in the expression level of this protein indicating that the significance of matriptase may vary from case to case. Matriptase protein expression was correlated with HER2 expression and highest expression was seen in HER2-positive cell lines, indicating a potential role in this subgroup. Stable overexpression of matriptase in two breast cancer cell lines had different consequences. In MDA-MB-231 human breast carcinoma cells the only noted consequence of matriptase overexpression was modestly impaired growth in vivo. In contrast, overexpression of matriptase in 4T1 mouse breast carcinoma cells resulted in visible changes in morphology, actin staining and cell to cell contacts. This correlated with downregulation of the cell-cell adhesion molecule E-cadherin. These results suggest that the functions of matriptase in breast cancer are likely to be variable and cell context dependent

Oncogenic Properties of Apoptotic Tumor Cells in Aggressive B Cell Lymphoma

BACKGROUND: Cells undergoing apoptosis are known to modulate their tissue microenvironments. By acting on phagocytes, notably macrophages, apoptotic cells inhibit immunological and inflammatory responses and promote trophic signaling pathways. Paradoxically, because of their potential to cause death of tumor cells and thereby militate against malignant disease progression, both apoptosis and tumor-associated macrophages (TAMs) are often associated with poor prognosis in cancer. We hypothesized that, in progression of malignant disease, constitutive loss of a fraction of the tumor cell population through apoptosis could yield tumor-promoting effects. RESULTS: Here, we demonstrate that apoptotic tumor cells promote coordinated tumor growth, angiogenesis, and accumulation of TAMs in aggressive B cell lymphomas. Through unbiased "in situ transcriptomics" analysis-gene expression profiling of laser-captured TAMs to establish their activation signature in situ-we show that these cells are activated to signal via multiple tumor-promoting reparatory, trophic, angiogenic, tissue remodeling, and anti-inflammatory pathways. Our results also suggest that apoptotic lymphoma cells help drive this signature. Furthermore, we demonstrate that, upon induction of apoptosis, lymphoma cells not only activate expression of the tumor-promoting matrix metalloproteinases MMP2 and MMP12 in macrophages but also express and process these MMPs directly. Finally, using a model of malignant melanoma, we show that the oncogenic potential of apoptotic tumor cells extends beyond lymphoma. CONCLUSIONS: In addition to its profound tumor-suppressive role, apoptosis can potentiate cancer progression. These results have important implications for understanding the fundamental biology of cell death, its roles in malignant disease, and the broader consequences of apoptosis-inducing anti-cancer therapy
