- ItemGrounded Theory Method and Symbolic Interactionism: Freedom of Conceptualization and the Importance of Context in Research(Institut für Qualitative Forschung, Internationale Akademie Berlin gGmbH, 2022-09-30) Hewitt S; Mills J; Hoare K; Sheridan NSymbolic interactionism (SI), a perspective used to understand human conduct, is commonly said to underpin grounded theory methodology (GTM). However, the purpose of GTM is to produce substantive explanatory social theory from data without reliance on prior assumptions. Therefore, some argue that SI is an unnecessary theoretical constraint on the principal aim of GTM —the free conceptualization of data. In this article we use examples from an ongoing constructionist grounded theory study into the negotiation of nurses' roles in general practice in New Zealand, to demonstrate how SI can inform GTM regarding conceptual development and context. We argue that by asking three questions from a symbolic interactionist perspective, at each stage of the research process, freedom of conceptualization may be enhanced and awareness of contextual matters promoted to better bridge world views.
- ItemGrounded theory: The FAQs(University of Alberta, 2019-10-21) Birks M; Hoare K; Mills JSince being developed as a research methodology in the 1960s, grounded theory (GT) has grown in popularity. In spite of its prevalence, considerable confusion surrounds GT, particularly in respect of the essential methods that characterize this approach to research. Misinformation is evident in the literature around issues such as the various approaches to GT, how long the process takes, the role of literature and preconceptions, generating and using data and strategies to produce theory. This article examines the most frequently asked questions about GT in an effort to demystify its purpose and use. Understanding the fundamental concepts of GT is critical to the correct use and application of GT methods and the ultimate production of theory that is grounded in data. More significantly, this understanding can prevent researchers encountering common pitfalls that can impede the process and impact the products of research.
- ItemOccurrence of genes encoding spore germination in Clostridium species that cause meat spoilage.(2022-02) Burgess SA; Palevich FP; Gardner A; Mills J; Brightwell G; Palevich NMembers of the genus Clostridium are frequently associated with meat spoilage. The ability for low numbers of spores of certain Clostridium species to germinate in cold-stored vacuum-packed meat can result in blown pack spoilage. However, little is known about the germination process of these clostridia, despite this characteristic being important for their ability to cause spoilage. This study sought to determine the genomic conditions for germination of 37 representative Clostridium strains from seven species (C. estertheticum, C. tagluense, C. frigoris, C. gasigenes, C. putrefaciens, C. aligidicarnis and C. frigdicarnis) by comparison with previously characterized germination genes from C. perfringens, C. sporogenes and C. botulinum. All the genomes analysed contained at least one gerX operon. Seven different gerX operon configuration types were identified across genomes from C. estertheticum, C. tagluense and C. gasigenes. Differences arose between the C. gasigenes genomes and those belonging to C. tagluense/C. estertheticum in the number and type of genes coding for cortex lytic enzymes, suggesting the germination pathway of C. gasigenes is different. However, the core components of the germination pathway were conserved in all the Clostridium genomes analysed, suggesting that these species undergo the same major steps as Bacillus subtilis for germination to occur.
