Towards a Theory of Software Development Expertise
Software development includes diverse tasks such as implementing new
features, analyzing requirements, and fixing bugs. Being an expert in those
tasks requires a certain set of skills, knowledge, and experience. Several
studies investigated individual aspects of software development expertise, but
what is missing is a comprehensive theory. We present a first conceptual theory
of software development expertise that is grounded in data from a mixed-methods
survey with 335 software developers and in literature on expertise and expert
performance. Our theory currently focuses on programming, but already provides
valuable insights for researchers, developers, and employers. The theory
describes important properties of software development expertise and which
factors foster or hinder its formation, including how developers' performance
may decline over time. Moreover, our quantitative results show that developers'
expertise self-assessments are context-dependent and that experience is not
necessarily related to expertise.Comment: 14 pages, 5 figures, 26th ACM Joint European Software Engineering

Children’s body composition and stress, the ChiBS study : aims, design, methods, population and participation characteristics
BACKGROUND: The last decades, the prevalence of childhood obesity has increased. Apart from other lifestyle factors, the effect of chronic psychosocial stress on the development of obesity has been recognized. However, more research is needed into the influence of chronic stress on appetite regulation, energy balance and body composition, as well as on the interaction with physical activity/sedentary behavior, diet and sleep in children. In this regard, the ChiBS study (Children’s Body composition and Stress) was designed at the Ghent University. Within this paper, we describe the aims, design, methods, participation and population characteristics of the ChiBS study. METHODS: The influence of chronic stress on changes in body composition is investigated over a two-year follow-up period (February-June 2010, 2011 and 2012) in primary-school children between 6 and 12 years old in the city Aalter (Flanders, Belgium). Stress is measured by child- and parent-reported stress-questionnaires, as well as by objective stress biomarkers (serum, salivary and hair cortisol) and heart rate variability. Body composition is evaluated using basic anthropometric measurements and air displacement plethysmography. Additional information on socio-economic status, medical history, physical activity, dietary intake and sleep are obtained by questionnaires, and physical activity by accelerometers. RESULTS: The participation percentage was 68.7% (N = 523/761), with 71.3% of the children willing to participate in the first follow-up survey. Drop-out proportions were highest for serum sampling (12.1%), salivary sampling (8.3%) and heart rate variability measurements (7.4%). DISCUSSION: The ChiBS project is unique in its setting: its standardized and longitudinal approach provides valuable data and new insights into the relationship between stress and changes in body composition in a large cohort of young children. In addition, this study allows an in-depth investigation of the validity of the different methods that were used to assess stress levels in children

Tutors as learners: overcoming barriers to learning ICT skills
This paper explores the use of ICT to provide distance training for UK Open University (OU) Associate lecturers (ALs) and identifies the range of outcomes and issues which emerged. There is an increasing demand from many of our students for the University to provide more facilities and functions (both administrative or course-related) online or by electronic mail. To this end the University has attempted to increase the awareness of these computing-related issues with ALs by offering various methods of increasing ICT skills. One programme involved a contingent of ALs participating in an online short course. This paper will summarise some of the qualitative feedback along with the quantitative results in order to establish whether this course did indeed assist in tutors gaining some new computing skills. Furthermore, tutors made many additional comments about the process of learning and the experience of being a learner. Many of the issues raised were found to be important when designing a programme of study for those who take courses as a form of staff development
Design and introduction of a quality of life assessment and practice support system: perspectives from palliative care settings
Background:
Quality of life (QOL) assessment instruments, including patient-reported outcome measures (PROMs) and patient-reported experience measures (PREMs), are increasingly promoted as a means of enabling clinicians to enhance person-centered care. However, integration of these instruments into palliative care clinical practice has been inconsistent. This study focused on the design of an electronic Quality of Life and Practice Support System (QPSS) prototype and its initial use in palliative inpatient and home care settings. Our objectives were to ascertain desired features of a QPSS prototype and the experiences of clinicians, patients, and family caregivers in regard to the initial introduction of a QPSS in palliative care, interpreting them in context.
Methods:
We applied an integrated knowledge translation approach in two stages by engaging a total of 71 clinicians, 18 patients, and 17 family caregivers in palliative inpatient and home care settings. Data for Stage I were collected via 12 focus groups with clinicians to ascertain desirable features of a QPSS. Stage II involved 5 focus groups and 24 interviews with clinicians and 35 interviews with patients or family caregivers during initial implementation of a QPSS. The focus groups and interviews were recorded, transcribed, and analyzed using the qualitative methodology of interpretive description.
Results:
Desirable features focused on hardware (lightweight, durable, and easy to disinfect), software (simple, user-friendly interface, multi-linguistic, integration with e-health systems), and choice of assessment instruments that would facilitate a holistic assessment. Although patient and family caregiver participants were predominantly enthusiastic, clinicians expressed a mixture of enthusiasm, receptivity, and concern regarding the use of a QPSS. The analyses revealed important contextual considerations, including: (a) logistical, technical, and aesthetic considerations regarding the QPSS as a technology, (b) diversity in knowledge, skills, and attitudes of clinicians, patients, and family caregivers regarding the integration of electronic QOL assessments in care, and (c) the need to understand organizational context and priorities in using QOL assessment data.
Conclusion:
The process of designing and integrating a QPSS in palliative care for patients with life-limiting conditions and their family caregivers is complex and requires extensive consultation with clinicians, administrators, patients, and family caregivers to inform successful implementation
A review of the use of information and communication technologies for dietary assessment
Presently used dietary-assessment methods often present difficulties for researchers and respondents, and misreporting errors are common. Methods using information and communication technologies (ICT) may improve quality and accuracy. The present paper presents a systematic literature review describing studies applying ICT to dietary assessment. Eligible papers published between January 1995 and February 2008 were classified into four assessment categories: computerised assessment; personal digital assistants (PDA); digital photography; smart cards. Computerised assessments comprise frequency questionnaires, 24 h recalls (24HR) and diet history assessments. Self-administered computerised assessments, which can include audio support, may reduce literacy problems, be translated and are useful for younger age groups, but less so for those unfamiliar with computers. Self-administered 24HR utilising computers yielded comparable results as standard methods, but needed supervision if used in children. Computer-assisted interviewer-administered recall results were similar to conventional recalls, and reduced inter-interviewer variability. PDA showed some advantages but did not reduce underreporting. Mobile phone meal photos did not improve PDA accuracy. Digital photography for assessing individual food intake in dining facilities was accurate for adults and children, although validity was slightly higher with direct visual observation. Smart cards in dining facilities were useful for measuring food choice but not total dietary intake. In conclusion, computerised assessments and PDA are promising, and could improve dietary assessment quality in some vulnerable groups and decrease researcher workload. Both still need comprehensive evaluation for micronutrient intake assessment. Further work is necessary for improving ICT tools in established and new methods and for their rigorous evaluatio
Medicines and driving: evaluation of training and software support for patient counselling by pharmacists
Background : The consumption of some psychotropic medicines has a negative effect on the fitness to drive. Pharmacists are expected to give useful advice to patients on their participation in traffic. However, almost no information is available on this topic.
Objective : To assess the effect of training and implementation of new dispensing guidelines with regard to driving-impairing medicines, in two types of dispensing support tools. User acceptance was measured as well as the effect on pharmacists' attitudes & awareness, self-reported behaviour and knowledge. Setting Pharmacists from East Flanders in Belgium.
Methods : Two intervention groups and a control group participated. The intervention groups followed a training and were provided with a dispensing support tool containing information on the effect of medicines on driving ability, which was either stand-alone (USB stick) or integrated into the daily used software (ViaNova). The three groups filled out a questionnaire prior to and after the intervention period.
Main outcome measure : Answers to a pre/post-questionnaire on attitudes and awareness, self-reported behaviour, knowledge and user acceptance.
Results : Many pharmacists were already strongly interested in the topic at the beginning of the study. Positive changes in attitude, self-reported behaviour and knowledge were measured mostly in the group of pharmacists for which the information was integrated in their daily used software. These pharmacists asked significantly more about the patients' driving experience, informed them more about driving-related risk and gave more detailed information on impairing effects of medicines. The knowledge of the participating pharmacists on the topic 'medicines and driving' remained generally low. The participants acknowledge the importance of being aware of the topic medicines and driving but they report a lack of information or education. They strongly prefer a tool that integrates the information in their daily used software.
Conclusion : Dispensing support tools with information on the potential impairing effect of a medicine on the fitness to drive increases awareness, reported risk communication behaviour as well as knowledge of pharmacists on this topic. Computerised dispensing support tools are most effective when the information is integrated into the daily used dispensing software
