EQUITY IN MATHEMATICS AND SCIENCE OUTCOMES: CHARACTERISTICS ASSOCIATED WITH HIGH AND LOW ACHIEVEMENT ON PISA 2006 IN IRELAND

Equity in education is a key concern internationally; however, it is rare that this issue is examined separately for low- and high-achieving students and concurrently across different subject domains. This study examines student and school background characteristics associated with low and high achievement in mathematics and science on the Programme for International Student Assessment. Based on the results of a multilevel multinomial model of achievement for each domain, findings indicate that a greater number of the variables examined are associated with low rather than high achievement. At student level, home language, intention to leave school early, socioeconomic status, grade level, cultural capital, and books in the home are significantly associated with achievement in mathematics and science. At school level, only school average socioeconomic status is statistically significant in the models. Significant gender differences are found in the distribution of high and low achievers, which vary across the domains. In mathematics, females are more likely to be low achievers while males are more likely to be high achievers. In science, gender interacts with early school-leaving intent whereas males intending to leave school early are more likely to be in the low-achieving group than females intending to leave early. Conclusions emphasise the need for targeting resources aimed at promoting equity in outcomes at student level as well as at school level. Future work may extend the current analyses by incorporating domain-specific variables or examining cross-country differences.     

Using communities of practice as a tool to analyse developing identity in online discussion

In this article, we address the methodological implications of analysing online discussion boards with a focus on participants' changing identities. More specifically, we propose the use of a Communities of Practice framework as a heuristic method for considering how participants' contributions to online discussion play a role in changing who they become, as opposed to what they learn. We argue that many analyses of online communication fail to take account of learning as a change in identity – what/who the learner is (becoming) – and focus mainly on the opportunity for cognitive development – what they know. In doing so, we use a single case study from a discussion board for secondary-aged students of mathematics which acts as a ‘telling case’ before demonstrating what this might say about other contexts for online learning. We argue that this has important implications for both research into, and the design of, online education.     

Evolving patterns of working: do they matter?

We consider how changing attitudes to computer use may alter the habits of students in the use of location and times of the day. We discover for one community the extent to which they absent themselves from the physical university and see some trends. We suggest that this is a deep change of habit, influenced by the ‘digital generation’, and seek qualitative results on what determines the modern student's keyboard behaviour. We present early evidence that, while students are indeed absenting themselves from formal computer facilities, some understanding of the benefits of the physical university remains intact.     

The managers guide to understanding,detecting, and thwarting computer crime: An international performance issue

Cyber crime poses an ever‐growing international threat to businesses. Organizations need to address this threat through a performance intervention by making managers aware of the reasons cyber crimes are committed so that they can detect and prevent them. This research details the primary types of cyber crime, describes and suggests managerial defenses to cyber crime, and reviews the importance of synchronized international legislation in the fight against cyber crime.     

Patch-guided facial image inpainting by shape propagation

Images with human faces comprise an essential part in the imaging realm. Occlusion or damage in facial portions will bring a remarkable discomfort and information loss. We propose an algorithm that can repair occluded or damaged facial images automatically, named ‘facial image inpainting＇. Inpainting is a set of image processing methods to recover missing image portions. We extend the image inpainting methods by introducing facial domain knowledge. With the support of a face database, our approach propagates structural information, i.e., feature points and edge maps, from similar faces to the missing facial regions. Using the interred structural information as guidance, an exemplar-based image inpainting algorithm is employed to copy patches in the same face from the source portion to the missing portion. This newly proposed concept of facial image inpainting outperforms the traditional inpainting methods by propagating the facial shapes from a face database, and avoids the problem of variations in imaging conditions from different images by inferring colors and textures from the same face image. Our system produces seamless faces that are hardly seen drawbacks.     

Early detection of fungal biomass on library materials

Library materials are susceptible to fungal deterioration. The paper constituents of archival materials are subjected to harmful physical and chemical processes as they are slowly consumed by fungi. Remediation of fungal contamination can be costly and risk further damage to fragile or previously degraded materials. Early detection of fungal growth would permit the use of relatively noninvasive treatments to remediate fungal contamination of artifacts before visible or lasting damage has occurred. Current methods used for the detection of microbial biomass, such as colony counts, microscopic biovolume estimation, and ergosterol analysis are expensive, time consuming, or are inappropriate for use with fungi. Beta-N-acetylhexosaminidase (EC 3.2.1.52) activity provides a rapid and reliable means of fungal detection on a variety of cultural heritage materials. Adapted for use on archival materials, fluorogenic 4-Methylumbelliferyl (MUF) labeled substrate N-acetyl-Beta-D-glucosamine (NAG) was used to detect fungal beta-N-acetylhexosaminidase activity. The fluorescence generated by minute quantities of fungi was quickly detected at an early stage of growth. The sensitivity of the assay was comparable to other biochemical techniques. The fluorometric assay was well-suited for early detection of fungal biomass on paper and assessment of the effectiveness of common remediation practices.     

A dynamic analytic approach to national innovation systems: The IC industry in Taiwan

The paper attempts to develop a mathematical model of the national innovation system (NIS) of Taiwan, particularly with regard to its integrated circuit (IC) industry. The method utilised is that of system dynamics (SD). Drawing on both questionnaire/in-depth interviews and computer simulation, the paper aims to increase insights into the dynamic processes of the Taiwanese IC industry system of innovation and understand the interdependence and interaction among capital flows, human resource flows, knowledge and technology flows, and product flows in the NIS. The paper concludes with some simulations of policy alternatives confronting the IC industry and the Taiwanese government.     

From Sportswear to Leisurewear: The Evolution of English Football League Shirt Design in the Replica Kit Era

The football shirt is of iconic significance, defining a club's visual identity through its role as sporting uniform and fan identifier, providing a canvas for commercial interactions and increasingly acting as the focus of nostalgia and collector culture. In this article we focus on the football shirt's extension from sportswear to a replica product worn as cross-generational leisurewear. We first consider how a replica's authenticity, its principal attribute, exists in objective, constructive and existential contexts. We then demonstrate how the subsequent focus of kit manufacturers and clubs on satisfying these differing interpretations of authenticity has influenced football shirt design. For two decades, replica kits were marketed as sportswear to children, with attempts to enhance the football shirt's authenticity through distinctiveness and exclusivity leading to copyrighted designs, manufacturer's logos and increased patterning. However, as the replica football shirt became adult leisurewear, the changing customer base led to retrospective and recycled shirt designs proclaiming a club's distinct identity through its heritage, fulfilling fans' nostalgic interpretations of a club's authentic kit, and reflecting fans' use of replica shirts to display their authenticity as a genuine fan. These ideals have also inspired a parallel retro-replica industry and, we argue, caused stagnation in the development of the aesthetic elements of contemporary kit design, which had previously demonstrated innovation interspersed with periods of consolidation, but had taken few retrospective turns. Genuine innovation in football shirt design has increasingly become restricted to technological advances and marketing strategies.     

The Diversity and Dynamics of Competition: Evidence from two local schooling markets

The policy of encouraging schools to compete has been justified on the basis of raising measured levels of attainment and widening choice. In this paper we review the basis for this policy, utilising the economic analysis of markets with a small number of providers. We note that in such markets, typical of local schooling markets, increased competition may generate diverse market behaviour and identify factors likely to produce rivalry and co-operation. We then present evidence of two apparently similar local schooling markets that exhibit very different levels and types of competition. We show how an assessment of the intensity of competition in a local schooling market depends on the particular indicators chosen. We review alternative interpretations for these differences in the nature of competition and relate to recent policy initiatives.
