Multimodal Literacy as a form of Communication : What is the state of the students at Dalarna University multimodal literacy?

Literacy is an invaluable asset to have, and has allowed for communication, documentation and the spreading of ideas since the beginning of the written language. With technological advancements, and new possibilities to communicate, it is important to question the degree to which people’s abilities to utilise these new methods have developed in relation to these emerging technologies. The purpose of this bachelor’s thesis is to analyse the state of students’ at Dalarna University mulitimodal literacy, as well as their experience of multimodality in their education. This has led to the two main research questions: What is the state of the students at Dalarna University multimodal literacy? And: How have the students at Dalarna University experienced multimodality in education? The paper is based on a mixed-method study that incorporates both a quantitative and qualitative aspect to it. The main thrust of the research paper is, however, based on a quantitative study that was conducted online and emailed to students via their program coordinators. The scope of the research is in audio-visual modes, i.e. audio, video and images, while textual literacy is presumed and serves as an inspiration to the study. The purpose of the study is to analyse the state of the students’ multimodal literacy and their experience of multimodality in education. The study revealed that the students at Dalarna University have most skill in image editing, while not being very literate in audio or video editing. The students seem to have had mediocre experience creating meaning through multimodality both in private use and in their respective educational institutions. The study also reveals that students prefer learning by means of video (rather than text or audio), yet are not able to create meaning (communicate) through it.

Investigating information systems analysts' possession of tacit organisational knowledge

Outsourcing of Information Technology (IT) services which are central to business strategy may be risky. Managers have made the outsourcing decision both to concentrate financially on the core competencies and to rid themselves of a troublesome and cost inefficient department. More recent research has, however, cast doubt on the promises of huge savings. In this paper, we consider the likelihood that outsourcing may lead to the loss of organisational knowledge - that organisations outsourcing their total Information Systems operations may also have lost irreplaceable tacit, cross-functional knowledge which subsisted within the minds of the professional systems analysts. The findings of our research revealed that expert systems analysts possess a unique organisational understanding and draw on this knowledge to operate efficiently in their environment. We present a model that will allow future researchers to build on our findings and examine whether outsourcing can lead to a loss of organisational memory.

Management and business issues for B2B eCommerce implementation

Until recently little research had been undertaken into the process of eCommerce implementation, especially in relation to the implementation of business-to-business (B2B) relationships. Given the complexity of this process we have, in this paper, endeavoured to contribute to what we perceive as a gap in the body of theory surrounding the implementation process in the extant business-to-business literature. We describe the findings of a series of multiple case studies comprising ten major Australian eCommerce initiators. In addition to confirming our earlier finding of the importance of nontechnical factors for the success of the implementation process we also present, through our case studies, the various management and business issues associated with the success or otherwise of B2B eCommerce implementation.

Development of an instrument to evaluate the quality of delivered information systems

Delivered information systems are an integral part of many organisations’ information technology infrastructure. Their dynamic nature creates new challenges, not the least of which is the need to measure the quality/effectiveness of these systems. Given the size of investment in these systems, it would be invaluable for business to formulate a fresh, simple, easy to administer, multi-dimensional instrument capable of measuring the quality of delivered information systems or applications. Such an instrument would provide a practical and efficient means to pinpoint areas that key stakeholders, ranging from end-users to managers, perceive as requiring attention. In this paper, we report on the development of one such instrument. This instrument addresses key areas of performance and uses multiple statements to enhance stakeholders’ understanding of these areas.

Adding value to online privacy for consumers: remedying deficiences in online privacy policies with an holistic approach

We present findings from a longitudinal, empirical study of online privacy policies. Our research found that although online privacy policies have improved in quality and effectiveness since 2000, they still fall well short of the level of privacy assurance desired by consumers. This study has identified broad areas of deficiency in existing online privacy policies, and offers a solution in the form of an holistic framework for the development, factors and content of online privacy policies for organizations. Our study adds to existing theory in this area and, more immediately, will assist businesses concerned about the effect of privacy issues on consumer Web usage.

Dissecting computer fraud : from definitional issues to a taxonomy

Computer frauds, while less dramatic than crimes of violence, can inflict significant damage at community, organizational or individual level. In order to properly quantify and mitigate the risk, computer frauds needs to be well understood. In this paper, in a conceptual-analytical research approach, we propose a dissection of computer fraud. First, we look into the elements of an offense, the act of fraud in general, than explain what is and what is not computer fraud. Next, from a prevention perspective, we propose a taxonomy of computer fraud with respect to perpetration platform, and to perpetration method. We believe that our contributions extend the existing knowledge of the phenomenon, and can assist those fighting computer fraud to better understand it and to design means of preventing and reporting it.

B2B e-commerce stages of growth; the strategic imperatives

Stages-of-growth has been the most popular approach used for strategy development and implementation. The major stages of growth models such as C. F. Gibson and R. F. Nolan (1974) have been widely discussed and are particularly useful in understanding the implementation of IS in organisations. These models might be more representative of e-commerce implementation, however, if they took into account more recent IS developments such as B2B e-commerce. Using a case study research undertaken in Australia, this study proposes a model of stages of growth based on the use of B2B e-commerce technologies and applications in Australian organisations. Four stages of growth proposed for B2B e-commerce implementation are (i) initial e-commerce; (ii) centralised e-commerce; (iii) looking inward for benefits; and (iv) global e-commerce.

Knowledge development and creation in email

Newly created knowledge is increasingly viewed as a highly valuable source of competitive advantage for business. Email is explored in its recently recognized role as a place of organizational knowledge development and creation, employing discourse analysis of email conversations as the research approach. This paper describes a knowledge development lifecycle derived from the empirical study, and provides insight into the nature of knowledge development and creation in organizations. We found that in selected email conversations, employees naturally and intuitively build purpose driven new knowledge incrementally and iteratively, crystallizing knowledge under construction by submitting it repeatedly to a range of key stakeholders for comment, until a 'consensus' is reached regarding the outcome. Our findings identify the process of knowledge qualification in organizational knowledge creation, and suggest that organizational knowledge may be politically constructed. The research results have the potential to assist organizations in understanding and facilitating processes and conditions for knowledge creation and development. The study also highlights the potential for email as a key component in a company's formal KM strategy.

How well do ecosystem-based planning units represent different componenets of biodiversity?

There are many proposals for managing biodiversity by using surrogates, such as umbrella, indicator, focal, and flagship species. We use the term biodiversity management unit for any ecosystem-based classificatory scheme for managing biodiversity. The sufficiency of biodiversity management unit classification schemes depends upon (1) whether different biotic elements (e.g., trees, birds, reptiles) distinguish between biodiversity management units within a classification (i.e., coherence within classes}; and (2) whether different biotic elements agree upon similarities and dissimilarities among biodiversity management unit classes (i.e., conformance among classes). Recent evaluations suggest that biodiversity surrogates based on few or single taxa are not useful. Ecological vegetation classes are an ecosystem-based classification scheme used as one component for biodiversity management in Victoria, Australia. Here we evaluated the potential for ecological vegetation classes to be used as biodiversity management units in the box-ironbark ecosystem of central Victoria, Australia. Eighty sites distributed among 14 ecological vegetation classes were surveyed in the same ways for tree species, birds, mammals, reptiles, terrestrial invertebrates, and nocturnal flying insects. Habitat structure and geographic separations also were measured, which, with the biotic elements, are collectively referred to as variables. Less than half of the biotic element-ecological vegetation class pairings were coherent. Generalized Mantel tests were used to examine conformance among variables with respect to ecological vegetation classes. While most tests were not significant, birds, mammals, tree species, and habitat structure together showed significant agreement on the rating of similarities among ecological vegetation classes. In this system, use of ecological vegetation classes as biodiversity management units may account reasonably well for birds, mammals, and trees; but reptiles and invertebrates would not be accommodated. We conclude that surrogates will usually have to be augmented or developed as hierarchies to provide general representativeness.

Patient engagement and coaching for health: the PEACH study- a cluster randomised controlled trial using the telephone to coach people with type 2 diabetes to engage with their GPs to improve diabetes care: a study protocol.

Background
The PEACH study is based on an innovative 'telephone coaching' program that has been used effectively in a post cardiac event trial. This intervention will be tested in a General Practice setting in a pragmatic trial using existing Practice Nurses (PN) as coaches for people with type 2 diabetes (T2D). Actual clinical care often fails to achieve standards, that are based on evidence that self-management interventions (educational and psychological) and intensive pharmacotherapy improve diabetes control. Telephone coaching in our study focuses on both. This paper describes our study protocol, which aims to test whether goal focused telephone coaching in T2D can improve diabetes control and reduce the treatment gap between guideline based standards and actual clinical practice.
Methods/design
In a cluster randomised controlled trial, general practices employing Practice Nurses (PNs) are randomly allocated to an intervention or control group. We aim to recruit 546 patients with poorly controlled T2D (HbA1c >7.5%) from 42 General Practices that employ PNs in Melbourne, Australia. PNs from General Practices allocated to the intervention group will be trained in diabetes telephone coaching focusing on biochemical targets addressing both patient self-management and engaging patients to work with their General Practitioners (GPs) to intensify pharmacological treatment according to the study clinical protocol. Patients of intervention group practices will receive 8 telephone coaching sessions and one face-to-face coaching session from existing PNs over 18 months plus usual care and outcomes will be compared to the control group, who will only receive only usual care from their GPs. The primary outcome is HbA1c levels and secondary outcomes include cardiovascular disease risk factors, behavioral risk factors and process of care measures.
Discussion
Understanding how to achieve comprehensive treatment of T2D in a General Practice setting is the focus of the PEACH study. This study explores the potential role for PNs to help reduce the treatment and outcomes gap in people with T2D by using telephone coaching. The intervention, if found to be effective, has potential to be sustained and embedded within real world General Practice.

Bayesian clustering with AutoClass explicitly recognises uncertainties in landscape classification

Clustering of multivariate data is a commonly used technique in ecology, and many approaches to clustering are available. The results from a clustering algorithm are uncertain, but few clustering approaches explicitly acknowledge this uncertainty. One exception is Bayesian mixture modelling, which treats all results probabilistically, and allows comparison of multiple plausible classifications of the same data set. We used this method, implemented in the AutoClass program, to classify catchments (watersheds) in the Murray Darling Basin (MDB), Australia, based on their physiographic characteristics (e.g. slope, rainfall, lithology). The most likely classification found nine classes of catchments. Members of each class were aggregated geographically within the MDB. Rainfall and slope were the two most important variables that defined classes. The second-most likely classification was very similar to the first, but had one fewer class. Increasing the nominal uncertainty of continuous data resulted in a most likely classification with five classes, which were again aggregated geographically. Membership probabilities suggested that a small number of cases could be members of either of two classes. Such cases were located on the edges of groups of catchments that belonged to one class, with a group belonging to the second-most likely class adjacent. A comparison of the Bayesian approach to a distance-based deterministic method showed that the Bayesian mixture model produced solutions that were more spatially cohesive and intuitively appealing. The probabilistic presentation of results from the Bayesian classification allows richer interpretation, including decisions on how to treat cases that are intermediate between two or more classes, and whether to consider more than one classification. The explicit consideration and presentation of uncertainty makes this approach useful for ecological investigations, where both data and expectations are often highly uncertain.

Nestedness in fragmented landscapes: birds of the box-ironbark forests of south-eastern Australia

Nestedness in biota as a function of species richness – biota of depauperate assemblages being non-random subsets of richer biotas – has been widely documented in recent years (see Wright et al. 1998, Oecologia 113: 1–20). Ordering sites by richness maximizes nestedness indices; however, ordering by other criteria such as area or isolation may be more ecologically interpretable. We surveyed birds in true fragments (35 in all), and in "reference areas" in large extant forest blocks (30 locations), of the same range of areas (10, 20, 40, 80 ha). The avifauna was divided into "bush birds"– species dependent on forest and woodland, and "open country" species. We looked at nestedness in four data sets: "bush birds" in fragments and reference areas, and "all birds" in fragments and in reference areas. All data sets were significantly nested. Ordering by area in all cases was not significantly less nested than ordering by richness. Ordering by area in fragments was significantly greater than in reference areas, but the differences in standardized nestedness indices were small (<15%). We identified those birds that had distributions among fragments that conformed strongly with area, those that were more randomly distributed and some species that were more likely to occupy the smallest fragments. Among the latter was a hyperaggressive, invasive, colonial native species (noisy miner Manorina melanocephala). A suite of small, insectivorous birds were more likely to strongly conform with expected distributions in relation to area, which was consistent with observations of their vulnerability to the effects of the noisy miner in smaller fragments.

The effects of exercise and adipose tissue lipolysis on plasma adiponectin concentration and adiponectin receptor expression in human skeletal muscle

Objective: It has been suggested that adiponectin regulates plasma free fatty acid (FFA) clearance by stimulating FFA uptake and/or oxidation in muscle. We aimed to determine changes in plasma adiponectin concentration and adiponectin receptor 1 and 2 mRNA expression in skeletal muscle during and after prolonged exercise under normal, fasting conditions (high FFA trial; HFA) and following pharmacological inhibition of adipose tissue lipolysis (low FFA trial; LFA). Furthermore, we aimed to detect and locate adiponectin in skeletal muscle tissue. Methods: Ten subjects performed two exercise trials (120 min at 50% VO2max). Indirect calorimetry was used to determine total fat oxidation rate. Plasma samples were collected at rest, during exercise and during post-exercise recovery to determine adiponectin, FFA and glycerol concentrations. Muscle biopsies were taken to determine adiponectin protein and adiponectin receptor 1 and 2 mRNA expression and to localise intramyocellular adiponectin. Results: Basal plasma adiponectin concentrations averaged 6.57±0.7 and 6.63±0.8 mg/l in the HFA and LFA trials respectively, and did not change significantly during or after exercise. In the LFA trial, plasma FFA concentrations and total fat oxidation rates were substantially reduced. However, plasma adiponectin and muscle adiponectin receptor 1 and 2 mRNA expression did not differ between trials. Immunohistochemical staining of muscle cross-sections showed the presence of adiponectin in the sarcolemma of individual muscle fibres and within the interfibrillar arterioles. Conclusion: Plasma adiponectin concentrations and adiponectin receptor 1 and 2 mRNA expression in muscle are not acutely regulated by changes in adipose tissue lipolysis and/or plasma FFA concentrations. Adiponectin is abundantly expressed in muscle, and, for the first time, it has been shown to be present in/on the sarcolemma of individual muscle fibres.
