The Art of Fault Injection

Classical greek philosopher considered the foremost virtues to be temperance, justice, courage, and prudence. In this paper we relate these cardinal virtues to the correct methodological approaches that researchers should follow when setting up a fault injection experiment. With this work we try to understand where the "straightforward pathway" lies, in order to highlight those common methodological errors that deeply influence the coherency and the meaningfulness of fault injection experiments. Fault injection is like an art, where the success of the experiments depends on a very delicate balance between modeling, creativity, statistics, and patience

Lines-of-inquiry and sources of evidence in work-based research

There is synergy between the investigative practices of police detectives and social scientists, including work-based researchers. They both develop lines-of-inquiry and draw on multiple sources of evidence in order to make inferences about people, trends and phenomena. However, the principles associated with lines-of-inquiry and sources of evidence have not so far been examined in relation to work-based research methods, which are often unexplored or ill-defined in the published literature. We explore this gap by examining the various direct and indirect lines-of-inquiry and the main sources of primary and secondary evidence used in work-based research, which is especially relevant because some work-based researchers are also police detectives. Clearer understanding of these intersections will be useful in emerging professional contexts where the work-based researcher, the detective, and the social scientist cohere in the one person and their research project. The case we examined was a Professional Studies programme at a university in Australia, which has many police detectives doing work-based research, and from their experience we conclude there is synergy between work-based research and lines of enquiry. Specifically, in the context of research methods, we identify seven sources of evidence: 1) creative, unstructured, and semi-structured interviews; 2) structured interviews; 3) consensus group methods; 4) surveys; 5) documentation and archives; 6) direct observations and participant observations; and 7) physical or cultural artefacts, and show their methodological features related to data and method type, reliability, validity, and types of analysis, along with their respective advantages and disadvantages. This study thereby unpacks and isolates those characteristics of work-based research which are relevant to a growing body of literature related to the messy, co-produced and wicked problems of private companies, government agencies, and non-government organisations and the research methods used to investigate them

The Experience of Informal Caregivers for Persons with Metastatic Cancer Perceptions of Support

Presented to the Faculty of the University of Alaska Anchorage in Partial Fulfillment of the Requirements for the Degree of MASTER OF SCIENCEPurpose/Objectives: To investigate the experience and perceptions of support of caregivers for persons with advanced cancer. Research Approach: A qualitative descriptive approach using focus groups to explore the caregiver experience. Setting: An outpatient oncology infusion center in southcentral Alaska. Participants: 14 adult caregivers of persons with stage IV cancer. Methodologic Approach: Participants attended one of two focus groups. They were asked to share their experiences as informal caregivers. Focus groups were digitally recorded and transcribed verbatim for analysis. Krueger’s method for content coding and data analysis was used to identify themes (1998). Findings: Key themes that emerged during data analysis included internal stressors such as emotional and psychological distress, and external stressors of needed financial support and nutritional information, suggesting the stated need of a more comprehensive care approach. Conclusions: Participants recognized needs but did not feel they were supported in accessing resources. The experience of caregiving was often abrupt in onset in this population and the overwhelming amount of information they received did not include enough information on the act of caregiving or the resources available. Implications for Nursing: Advanced practice nurses are instrumental in identifying and addressing caregiver needs. As patient educators and advocates, they provide education and resource support to both the patients and the caregivers in an effort to minimize caregiver exhaustion

Trust and reciprocity effect on electronic word-of-mouth in online review communities

Purpose Social media developments in the last decade have led to the emergence of a new form of word of mouth (WOM) in the digital environment. Electronic word-of-mouth (eWOM) is considered by many scholars and practitioners to be the most influential informal communication mechanism between businesses and potential and actual consumers. The purpose of this paper is to extend knowledge about WOM in this new context by proposing a conceptual framework that enables a better understanding of how trust and reciprocity influence eWOM participation in ORCs. Design/methodology/approach This study applies non-probability convenience sampling technique to conduct a quantitative study of data from an online survey of 189 members of ORCs. Partial least squares (PLS) is used to analyse the correlations between individuals’ intention to seek opinion, to give their own opinion and to pass on the opinion of another within ORCs. Findings The data analysis reveals that opinion seeking within ORCs had a direct effect on opinion giving and opinion passing. Ability trust and integrity trust had a positive effect on opinion seeking, while benevolence trust had a direct positive effect on opinion passing. Reciprocity had a direct impact on opinion passing. While reciprocity did not affect opinion giving, the relationship between these two concepts was mediated by integrity trust. Research limitations/implications By studying the complexities that characterise the relationships between reciprocity, trust and eWOM, the study extends understanding of eWOM in ORCs. Originality/value To the best of the authors’ knowledge, this is one of only a few papers that have examined the complex interrelationships between reciprocity, trust and eWOM in the context of ORCs

Inside International Development Organisations: Socially Constructing Judgement in-the-Moment

This exploratory study aimed, first, to build new knowledge on how senior managers of international development organisations defined judgement and how they made sense of it in the context of their leadership roles and work environments. A secondary aim was to explore methodologies and methods, specifically unstructured interviews and observations, to be used in the PhD phase to study the social phenomenon of judgement. Using an ethnographic and reflexive approach, this study addressed the question: How do managers understand their use of judgement ‘in-the-moment’ in practice? Results from the two participating organisations suggest that there are diverse interpretations of the meaning of ‘judgement’; it is a socially constructed process; used in uncertain situations; and influenced by time and space. These findings contribute to our understanding of how judgement in-the-moment is perceived inside an understudied area: the everyday context of small international development organisations. Theoretically, this study complements the existing literature with a social constructionist perspective and draws linkages to judgement as a constitutive element of sensemaking. Methodologically, the reflexive approach taken builds awareness of examining the ‘multiple selves’ and how researchers influence their research and are influenced by it as subject and object. The validity, methodological issues, limitations and implications for future research are also discussed

Forming collaborative parent-teacher relationships to increase parental involvement

This document reviews and summarizes the importance of parentteacher relationships and parental involvement in education. Both benefits and barriers will be discussed. Strategies and plans are provided as suggestions for teachers working with diverse populations. The importance of collaborative relationships and parental involvement are discussed for parents and teachers of children who are deaf or hard of hearing

Qualitative software engineering research -- reflections and guidelines

Researchers are increasingly recognizing the importance of human aspects in software development and since qualitative methods are used to, in-depth, explore human behavior, we believe that studies using such techniques will become more common. Existing qualitative software engineering guidelines do not cover the full breadth of qualitative methods and knowledge on using them found in the social sciences. The aim of this study was thus to extend the software engineering research community's current body of knowledge regarding available qualitative methods and provide recommendations and guidelines for their use. With the support of an epistemological argument and a literature review, we suggest that future research would benefit from (1) utilizing a broader set of research methods, (2) more strongly emphasizing reflexivity, and (3) employing qualitative guidelines and quality criteria. We present an overview of three qualitative methods commonly used in social sciences but rarely seen in software engineering research, namely interpretative phenomenological analysis, narrative analysis, and discourse analysis. Furthermore, we discuss the meaning of reflexivity in relation to the software engineering context and suggest means of fostering it. Our paper will help software engineering researchers better select and then guide the application of a broader set of qualitative research methods.Comment: 30 page
