<p>Human Computer Interaction research has a unique challenge in understanding the activity systems of creative professionals, and designing the user-interfaces to support their work. In these activities, the user is involved in the process of building and editing complex digital artefacts through a process of continued refinement, as is seen in computer aided architecture, design, animation, movie-making, 3D modelling, interactive media (such as shockwave-flash), as well as audio and music production. This thesis examines the ways in which abstraction mechanisms present in music production systems interplay with producers' activity through a collective case study of seventeen professional producers. From the basis of detailed observations and interviews we examine common abstractions provided by the ubiquitous multitrack-mixing metaphor and present design implications for future systems.</p>

Purpose This study examined caregiver perceptions of their child's language and literacy disorder as influenced by communications with their speech-language pathologist. Method The participants were 12 caregivers of 10 school-aged children with language and literacy disorders. Employing qualitative methods, a collective case study approach was utilized in which the caregiver(s) of each child represented one case. The data came from semistructured interviews, codes emerged directly from the caregivers' responses during the interviews, and multiple coding passes using ATLAS.ti software were made until themes were evident. These themes were then further validated by conducting clinical file reviews and follow-up interviews with the caregivers. Results Caregivers' comments focused on the types of information received or not received, as well as the clarity of the information. This included information regarding their child's diagnosis, the long-term consequences of their child's disorder, and the connection between language and reading. Although caregivers were adept at describing their child's difficulties and therapy goals/objectives, their comments indicated that they struggled to understand their child's disorder in a way that was meaningful to them and their child. Conclusions The findings showed the value caregivers place on receiving clear and timely diagnostic information, as well as the complexity associated with caregivers' understanding of language and literacy disorders. The findings are discussed in terms of changes that could be made in clinical practice to better support children with language and literacy disorders and their families.

AbstractAdditive manufacturing (AM) is a versatile technology that could add flexibility in manufacturing processes, whether implemented alone or along other technologies. This technology enables on-demand production and decentralized production networks, as production facilities can be located around the world to manufacture products closer to the final consumer (decentralized manufacturing). However, the wide adoption of additive manufacturing technologies is hindered by the lack of experience on its implementation, the lack of repeatability among different manufacturers and a lack of integrated production systems. The later, hinders the traceability and quality assurance of printed components and limits the understanding and data generation of the AM processes and parameters. In this article, a design strategy is proposed to integrate the different phases of the development process into a model-based design platform for decentralized manufacturing. This platform is aimed at facilitating data traceability and product repeatability among different AM machines. The strategy is illustrated with a case study where a car steering knuckle is manufactured in three different facilities in Sweden and Italy.

The World Health Organization (WHO) recommends exclusive breastfeeding for six months and continuation of breastfeeding for up to two years. Formal child care has an important role in supporting breastfeeding, as many Australian infants commence care before two years of age. Currently, little is known about support or barriers in child care contexts. The present qualitative instrumental case study explores practices which protect, promote and support breastfeeding at a child care centre located in the Australian Capital Territory’s outer suburbs. Extending from a previously published collective case study, a cultural-institutional focus of analysis was used to explore the roles of proximity, flexibility and communication in supporting breastfeeding within a child care centre located close to an infant’s home. Interviews with centre staff and mothers, triangulated with observations of the centre environment and policy documents provide insight into the environment. Affirming the roles of flexibility in routine and staff rostering and two-way communication, findings suggest longer-term benefits may be derived from selecting a child care centre close to an infant’s home, provided mothers can overcome barriers to breastmilk expression in the workplace. The study recognises the role of non-lactating caregivers in the transition to formal child care, and of the support culture for educators who breastfeed. This study extends the knowledge base of breastfeeding support interventions in the child care setting to inform future research and policy.

Trainee Competence

Abstract Introduction Workplace-based assessment in competency-based medical education employs entrustment-supervision scales to suggest trainee competence. However, clinical supervision involves many factors and entrustment decision-making likely reflects more than trainee competence. We do not fully understand how a supervisor’s impression of trainee competence is reflected in their provision of clinical support. We must better understand this relationship to know whether documenting level of supervision truly reflects trainee competence. Methods We undertook a collective case study of supervisor-trainee dyads consisting of attending internal medicine physicians and senior residents working on clinical teaching unit inpatient wards. We conducted field observations of typical daily activities and semi-structured interviews. Data was analysed within each dyad and compared across dyads to identify supervisory behaviours, what triggered the behaviours, and how they related to judgments of trainee competence. Results Ten attending physician-senior resident dyads participated in the study. We identified eight distinct supervisory behaviours. The behaviours were enacted in response to trainee and non-trainee factors. Supervisory behaviours corresponded with varying assessments of trainee competence, even within a dyad. A change in the attending’s judgment of the resident’s competence did not always correspond with a change in subsequent observable supervisory behaviours. Discussion There was no consistent relationship between a trigger for supervision, the judgment of trainee competence, and subsequent supervisory behaviour. This has direct implications for entrustment assessments tying competence to supervisory behaviours, because supervision is complex. Workplace-based assessments that capture narrative data including the rationale for supervisory behaviours may lead to deeper insights than numeric entrustment ratings.

This article investigates the entrepreneurial beliefs/attitudes, ambitions, expectations, goals and visions of rural women who choose to cooperate and found Women's Rural cooperatives in the Prefecture of Heraklion on the island of Crete. The results of a qualitative study involving a sample of eight chairwomen of rural women's established Traditional Food Production cooperatives indicated that the traditional domestic roles (housewife, mother), the low level of education, the lack of professional skills, enterprise experience and mostly the unwillingness of rural women to undertake enterprise risk, have turned them toward an enterprise model that lacks modern business methods in the use of quality control production systems, in the production of Protected Geographical Identification Goods and/or Certified Local Traditional Food and/or Organic Products, in the use of new organizing and managing technologies, in advertising and promoting products and in administrative renewal.

Study Approach

Purpose – This study aims to explore the phenomenon of training engagement from the trainers’ perspective. Specifically, two questions guided this inquiry. First, how do trainers define engagement in the training context? and What strategies do trainers use to engage trainees? Design/methodology/approach – The collective case study approach was adopted for this qualitative study. Seven cases were selected for in-depth analyses. Data were collected through individual, face-to-face interviews and analyzed using the constant comparative analysis method. Findings – Major findings suggest that engaging training practices take various forms. They include being trainee-centered, maximizing learning through entertaining and interesting instruction, accommodating different learning styles, eliciting trainee participation by creating an encouraging learning environment and connecting with trainees by building rapport early in a training session. Research limitations/implications – The small sample limits the generalizability of the findings. However, this study expands training literature by focusing on an under-explored research area, the role of engaging trainees in maximizing learning outcomes. Practical implications – For trainers, this study offered some specific strategies they can use to engage learners in the training context to achieve desired learning outcomes. In addition, the seven cases selected for this study may be used as a benchmark against which both experienced and novice trainers compared their own practices. Originality/value – This is one of very few qualitative studies with a focus on emotional aspects involved in training. The rich data from this study shed light on areas for future improvement, particularly regarding how to effectively engage trainees to maximize learning outcomes.

Leading Role

Research on street-level bureaucrats has examined the various ways in which these professionals have implemented public policies in areas such as healthcare, education, and security, often emphasizing the role played by discretion in the implementation process. Despite its importance, the concept of street-level bureaucracy has scarcely been approached by housing studies. This study focuses on the role of street-level workers in the delivery of public housing to the lower-income population. We affirm the value of complementing street-level discretion with the concept of proximity, a premise borrowed from the microfinance literature, to increase the understanding of the interactions and relationships established between street-level workers and policy recipients during the implementation process. Such complementarity may contribute to a more accurate understanding of the housing policy implementation dynamics on the street-level and the possible adjustments to meet local needs. To explore this issue, we used a theoretical lens inspired by Goffman’s frame analysis that points to the importance of relational mechanisms that characterize the interactions between street-level workers and beneficiaries. These lenses were applied to a collective case study of Minha Casa Minha Vida-Entidades, a Brazilian subprogram in which street-level workers linked to social housing movements assume a leading role in the planning and execution of interventions. The results indicate that the combination of proximity and discretion has a positive influence on the implementation of housing policies. Our analysis shows the existence of nonprofit-oriented arrangements that may present different features and nuances at the implementation (micro) level and contribute to the (macro) debate on housing policies.
