Prepared for Practice? Exploring and Evaluating the First Six Months of Post-qualified Practice in Social Work

This project explores how effective the Social work degree has been in enabling graduates to feel prepared for the practice of social work. Quantitative and qualitative data from online questionnaires and interviews with twelve graduates revealed that graduates perceived they were more confident, despite coming from a background where they were already practicing. They identified ways that this confidence (including in ICT and IL skills) has contributed to their preparedness for practice and their willingness to shape and challenge practices. Areas of practice where graduates felt least prepared included working with hostile service users. In terms of ICT skills development, variations in systems and technologyrelated practices resulted in tensions between the degree providing supportive guidance which fit particular software or social work settings compared with less supportive generic guidance which might be more widely applicable. IL skills were perceived to have more generic applicability

A Framework for File Format Fuzzing with Genetic Algorithms

Secure software, meaning software free from vulnerabilities, is desirable in today\u27s marketplace. Consumers are beginning to value a product\u27s security posture as well as its functionality. Software development companies are recognizing this trend, and they are factoring security into their entire software development lifecycle. Secure development practices like threat modeling, static analysis, safe programming libraries, run-time protections, and software verification are being mandated during product development. Mandating these practices improves a product\u27s security posture before customer delivery, and these practices increase the difficulty of discovering and exploiting vulnerabilities. Since the 1980\u27s, security researchers have uncovered software defects by fuzz testing an application. In fuzz testing\u27s infancy, randomly generated data could discover multiple defects quickly. However, as software matures and software development companies integrate secure development practices into their development life cycles, fuzzers must apply more sophisticated techniques in order to retain their ability to uncover defects. Fuzz testing must evolve, and fuzz testing practitioners must devise new algorithms to exercise an application in unexpected ways. This dissertation\u27s objective is to create a proof-of-concept genetic algorithm fuzz testing framework to exercise an application\u27s file format parsing routines. The framework includes multiple genetic algorithm variations, provides a configuration scheme, and correlates data gathered from static and dynamic analysis to guide negative test case evolution. Experiments conducted for this dissertation illustrate the effectiveness of a genetic algorithm fuzzer in comparison to standard fuzz testing tools. The experiments showcase a genetic algorithm fuzzer\u27s ability to discover multiple unique defects within a limited number of negative test cases. These experiments also highlight an application\u27s increased execution time when fuzzing with a genetic algorithm. To combat increased execution time, a distributed architecture is implemented and additional experiments demonstrate a decrease in execution time comparable to standard fuzz testing tools. A final set of experiments provide guidance on fitness function selection with a CHC genetic algorithm fuzzer with different population size configurations

Practices and trends of telework in the Portuguese industry: the results of surveys in the textile, metal and software sectors

The aim of the TeleRisk Project on labour relations and professional risks within the context of teleworking in Portugal – supported by IDICT – Institute for Development and Inspection of Working Conditions (Ministry of Labour), is to study the practices and forms of teleworking in the manufacturing sectors in Portugal. The project chose also the software industry as a reference sector, even though it does not intend to exclude from the study any other sector of activity or the so-called “hybrid” forms of work. However, the latter must have some of the characteristics of telework. The project thus takes into account the so-called “traditional” sectors of activity, namely textile and machinery and metal engineering (machinery and equipment), not usually associated to this type of work. However, telework could include, in the so-called “traditional” sectors, other variations that are not found in technologically based sectors. One of the evaluation methods for the dynamics associated to telework consisted in carrying out surveys by means of questionnaires, aimed at employers in the sectors analysed. This paper presents some of the results of those surveys. It is important to mention that, being a preliminary analysis, it means that it does not pretend to have exhausted all the issues in the survey, but has meant that it shows the bigger tendencies, in terms of teleworking practices, of the Portuguese industry.teleworking; organisation of work; Portugal; manufacturing

Designing for mod development: user creativity as product development strategy on the firm-hosted 3D software platform

The thesis is designed to improve our understanding of user participation in Web-based development practices in the commercial setting of the 3D software industry. It aims to investigate whether the creative capacities of users and their contributions to the online firm-hosted 3D platform are indicative of a novel configuration of production that influences the processes of product development across firm boundaries. The thesis mobilizes the user participation literature developing in media research as its main theoretical framework. It builds on insights derived from work on user participation in media sites as seen through a cultural lens, in particular, as developed in Henry Jenkins' notions of 'participatory' and 'convergence culture'. The user participation literature is supported by a combination of insights drawn from work on communities of practice and user-centred innovation so as to offer a more robust approach to examine and appreciate the firm-hosted 3D platform as a site of user participation. More specifically, the conceptual framework for the study provides a basis for an examination of the ways a software developer finn encourages user participation in a market and of how this enables and facilitâtes particular modes of user creativity. These are shown to shape and maintain a firm-hosted platform that aids product development efforts that are expected to benefit the developer fimi. An empirical study of the platform, Second Life, provides the basis for the analysis of finn-user interactions which are shown to underpin a distinctive finn leaming process in the context of product development that occurs across permeable fimi boundaries. The thesis yields insight into the way a developer firm invites its user base to partner with it in product development, indicating how aspects of user participation associated with non-market dynamics are embedded in commercial activity and professionalism. The pivotal role of users is revealed in the design, development and sustainability of a firm-hosted 3D product. The findings point to interesting relationships between the distinctive creative capacities of users and the range of capabilities afforded by the firm-provided design space. Variations in user participation and contributions to product development suggest that particular patterns of learning opportunities occur. The analysis yields several new concepts including a 'modification effect market' which are used to extend existing conceptualizations of user participation in digitai development practices in the commercial setting of the 3D software industry
