Choosing qualitative methods for entrepreneurial cognition research : a canonical development approach

This article presents a structured, manageable approach to the complex problem of how to choose, from the vast arsenal loosely labeled "qualitative methods," sets of techniques appropriate to advancement of the emerging field of entrepreneurial cognition. Summary consideration is given to four key issues of philosophical context as a necessary predicate to presentation of a "canonical development" approach, stylized in diagrammatic form. The approach is able to accommodate due regard for both methodological controversy and operational complexity without being overwhelmed by either. Three illustrative examples indicate how use of the approach can stimulate a researcher to create productive matches between questions evolved from the entrepreneurial cognition canon and techniques selected from the complex array of qualitative methods.

Associations between fatty acids in colostrum and breast milk and risk of allergic disease

Background Exposure to n-3 polyunsaturated fatty acids (PUFA) in early life is hypothesized to offer protection against atopic disease. However, there is controversy in this area, and we have previously observed that high levels of n-3 fatty acid (FA) in colostrum are associated with increased risk of allergic sensitization.
Objective The aim of the study was to assess the relationship between FA profile in breast milk and risk of childhood atopic disease.
Methods A high-risk birth cohort was recruited, and a total of 224 mothers provided a sample of colostrum (n = 194) and/or 3-month expressed breast milk (n = 118). FA concentrations were determined by gas chromatography. Presence of eczema, asthma and rhinitis were prospectively documented up to 7 years of age.
Results High levels of n-3 22:5 FA (docosapentaenoic acid, DPA) in colostrum were associated with increased risk of infantile atopic eczema [odds ratio (OR) = 1.66 per 1 standard deviation increase, 95% confidence interval (CI) = 1.11–2.48], while total n-3 concentration in breast milk was associated with increased risk of non-atopic eczema (OR = 1.60, 95% CI = 1.03–2.50). Higher levels of total n-6 FA in colostrum were associated with increased risk of childhood rhinitis (OR = 1.59, 95% CI = 1.12–2.25). There was no evidence of associations between FA profile and risk of asthma.
Conclusion In this cohort of high-risk children, a number of modest associations were observed between FA concentrations in colostrum and breast milk and allergic disease outcomes. Further research in this area with larger sample sizes is needed.

'The C Words': clitorises, childhood and challenging compulsory heterosexuality discourses with pre-service primary teachers

This paper reports on accidental ethnographic research. It arose unexpectedly out of the everyday teaching of first-year pre-service primary teachers at an Australian university. Via narrative, self-reflexivity, and student responses, we explore the interwoven workings of heteronormative, gendernormative and misogynist discourses when a chapter from Queering Elementary Education in the Course Reader created controversy, moral panic and resistance among students. The paper then charts the implementation of various strategies and interventions by the three authors of the paper: Greg, the lecturer; Maria, the Reading's author; and Steph, the Reading's protagonist. While outlining the subsequent shifts in student responses and discourses, we also problematise particular aspects of the processes of intervention where they still point to the insidious power and overarching framework of heteronormativity and gendernormativity that require ongoing challenges.

Adventures of punctuated equilibria : a struggle for authority in the evolutionary sciences

The theory of ‘punctuated equilibria’ was formulated by two paleontologists, Niles Eldredge and Stephen Gould, in 1972 and has been the focus of considerable controversy within the evolutionary sciences ever since. The primary intentions of this thesis are to relate the history of punctuated equilibria and to examine how it has affected evolutionary science. Several modes of analysis have been used to illuminate the history: The sociological perspectives of Pierre Bourdieu and Bruno Latour (who see scientific debate as a ‘struggle for authority’); Rhetorical analysis of some of the key documents; Communication with practising scientists via questionnaires and correspondence; Citation Analysis. Chapter 1 gives a short summary of the history and introduces the methods and socio-philosophical perspectives used to illuminate the history. Chapters 3 and 4 examine the rhetorical process by which Eldredge and Gould constructed the ‘punctuationist revolution’. Chapters 2, 3, 5 and 6 relate the history of punctuated equilibria.

A simple two-axiom characterization of the Nash solution

The oldest and best-known cooperative bargaining solution concept is the Nash solution. Nash [2] characterized his seminal solution concept by using the axioms of ‘Independence of Irrelevant Alternatives’ (IIA), ‘Weak Pareto Optimality’ (WPO), ‘Symmetry’ (SYM), and ‘Scale Invariance’ (SI). Except for WPO, these axioms have been at the center of controversy (especially the most crucial axiom, IIA). This paper considers a new and simple axiom ‘Focal Relevance of a Pareto-optimal Midpoint’ (FRPM). It turns out that the Nash solution can be characterized by WPO and FRPM only.

An empirical and logical exploration of the strategic compatibility of best practice and product innovation : preliminary insights from Australian and New Zealand manufacturing industry

In an attempt to enhance debate focused on an established academic controversy, this study re-investigated selected data from the 1994 AMC survey of Australian and New Zealand manufacturing practices to test the hypothesis that best practice and product innovation may be incompatible generic business strategies. A modification of Robert G. Cooper’s Stage-Gate product development model was used as a theoretical framework to create a measurable construct of ‘product innovation’ as a strategy and compare two groups: firms committed to a best practice strategy (BPs) and firms not utilising best practice (Non-BPs). Eight variables were scrutinised. After logical critique was added to statistical data analysis, four major insights emerged.

(1) Tests yielded several statistically significant but substantively inconclusive results because both studied groups had nearly identical profiles in rating innovation as the factor of lowest importance to commercial success and because the definitional framework which guided construction of the survey instrument treated innovation as a second-order issue. (2) Currently, best practice and product innovation are logically incompatible by definition. (3) Even if the definition of best practice were changed, it is likely that the additional key process of innovation would remain incompatible with the existing key process of benchmarking. (4) However, until the definition of best practice does make an attempt to include innovation as a key process rather than an outcome, testing any hypothesis of strategic compatibility between a best practice focus and an innovation focus will be both empirically difficult and logically unnecessary.

The use of heuristics in valuation practice : implications in a changing market

Despite the existence of prescribed frameworks, valuation remains a cause of much controversy and variety of opinion. It does not matter whether procedures are undertaken in exactly the same way, the conclusion of ‘value’ will vary from valuer to valuer – sometimes considerably. This uncertainty within valuation is founded on property’s heterogeneous nature and the imperfect market that is the property market; in addition to the unpredictability of human behaviour in making judgements (French and Gabrielli 2004). Uncertainty, in valuation is found in the amalgam of locational, physical and legal characteristics and innumerable other forces which control and energise the property market (Whipple 1995). Particular irregular occurrences, or drastic changes in property markets, from either within market evolution or external forces, for example the creation of global financial markets, cause further uncertainty for valuers and provides challenges in identifying ‘market value’ in valuation practice. The praxis of valuation in a commercial sense navigates this complexity using a combination of algorithms and heuristics to identify the value of a property. The application of theoretical mathematical algorithms based on economic theory (Brown 1995), is augmented by valuers’ ability to apply appropriate adjustment based on their knowledge of the market, their ability to analyse, assess and compare the attributes of a property in comparison to its market, and their practical experience (Sliogeriene 2008). Despite the necessity of algorithms, the application of appropriate adjustments and assumptions are important in arriving at a value. This paper is a critical reflection on the basis of valuation practice as guided by standards, methods, and ethics (algorithms), and the use of heuristics in practice. This is important because changes within property markets challenge the inter-relationship between these two aspects of valuation practice. Through the authors’ industry experience and a review of previous research and statements of practice norms this paper provides an analysis of the ability of valuers to address market change in their valuation practices.

It was an experience that totally blew up in my face : Steve Railsback and Turkey shoot

The schlock horror film Turkey Shoot is widely regarded as one of the most disreputable Australian exploitation titles in a genre already well noted for controversy. This short article frames the controversies that surround the film from production to critical reception, which sets the scene for an interview by Mark Harley with the film's star Steve Railsback, who reflects on the movie's production, his role, the controversy and the film's reception.

Analysis of Australian politicians speeches

While competing interpretations of Australian history occasionally attract controversy, there is a need for a comprehensive analysis, over time, of the significance of histories and history making for Australian politicians. In taking the longer view of Australian political speech and thought since the Federation, this data will provide a stronger foundation for both political engagement with historical themes and public appreciation of the continuing role of history in contemporary policy debates. The data comprises comprehensive qualitative analysis, using key search terms and themes, over time, of speeches of Australian politicians. Sources used include Hansard, other occasional speeches in public records, political party records, and Australian Parliamentary Library resources.

Ecological niche modelling and DNA sequencing support a new, morphologically cryptic beetle species unveiled by DNA barcoding

Background: DNA sequencing techniques used to estimate biodiversity, such as DNA barcoding, may reveal cryptic species. However, disagreements between barcoding and morphological data have already led to controversy. Species delimitation should therefore not be based on mtDNA alone. Here, we explore the use of nDNA and bioclimatic modelling in a new species of aquatic beetle revealed by mtDNA sequence data.

Methodology/Principal Findings: The aquatic beetle fauna of Australia is characterised by high degrees of endemism, including local radiations such as the genus Antiporus. Antiporus femoralis was previously considered to exist in two disjunct, but morphologically indistinguishable populations in south-western and south-eastern Australia. We constructed a phylogeny of Antiporus and detected a deep split between these populations. Diagnostic characters from the highly variable nuclear protein encoding arginine kinase gene confirmed the presence of two isolated populations. We then used ecological niche modelling to examine the climatic niche characteristics of the two populations. All results support the status of the two populations as distinct species. We describe the south-western species as Antiporus occidentalis sp.n.

Conclusion/Significance: In addition to nDNA sequence data and extended use of mitochondrial sequences, ecological niche modelling has great potential for delineating morphologically cryptic species. © 2011 Hawlitschek et al.

The role of micro-organisms (staphylococcus aureus and Candida Albicans) in the pathogenesis of breast pain and infection in lactation women : study protocol

Background: The CASTLE (Candida and Staphylococcus Transmission: Longitudinal Evaluation) study will investigate the micro-organisms involved in the development of mastitis and “breast thrush” among breastfeeding women. To date, the organism(s) associated with the development of breast thrush have not been identified. The CASTLE study will also investigate the impact of physical health problems and breastfeeding problems on maternal psychological health in the early postpartum period.

Methods/Design: The CASTLE study is a longitudinal descriptive study designed to investigate the role of Staphylococcus spp (species) and Candida spp in breast pain and infection among lactating women, and to describe the transmission dynamics of S. aureus and Candida spp between mother and infant. The relationship between breastfeeding and postpartum health problems as well as maternal psychological well-being is also being investigated. A prospective cohort of four hundred nulliparous women who are at least thirty six weeks gestation pregnant are being recruited from two hospitals in Melbourne, Australia (November 2009 to June 2011). At recruitment, nasal, nipple (both breasts) and vaginal swabs are taken and participants complete a questionnaire asking about previous known staphylococcal and candidal infections. Following the birth, participants are followed-up six times: in hospital and then at home weekly until four weeks postpartum. Participants complete a questionnaire at each time points to collect information about breastfeeding problems and postpartum health problems. Nasal and nipple swabs and breast milk samples are collected from the mother. Oral and nasal swabs are collected from the baby. A telephone interview is conducted at eight weeks postpartum to collect information about postpartum health problems and breastfeeding problems, such as mastitis and nipple and breast pain.

Discussion: This study is the first longitudinal study of the role of both staphylococcal and candidal colonisation in breast infections and will help to resolve the current controversy about which is the primary organism in the condition known as breast thrush. This study will also document transmission dynamics of S. aureus and Candida spp between mother and infant. In addition, CASTLE will investigate the impact of common maternal physical health symptoms and the effect of breastfeeding problems on maternal psychological well-being.

Religion in Victoria's government schools : a timely debate

While the role of religion in Australian schools has been vigorously debated since the 1870s, it has recently generated considerable controversy, particularly in the State of Victoria. Despite the Victorian Government’s positive record of promoting multifaith engagement, Christian volunteers – provided by ACCESS Ministries - currently teach 96% of students enrolled in Special Religious Instruction (SRI) classes in Victoria’s Government schools.

Developing a placebo-controlled trial in surgery : issues of design, acceptability and feasibility

Background: Surgical placebos are controversial. This in-depth study explored the design, acceptability, and feasibility issues relevant to designing a surgical placebo-controlled trial for the evaluation of the clinical and cost effectiveness of arthroscopic lavage for the management of people with osteoarthritis of the knee in the UK.
Methods: Two surgeon focus groups at a UK national meeting for orthopaedic surgeons and one regional surgeon focus group (41 surgeons); plenary discussion at a UK national meeting for orthopaedic anaesthetists (130 anaesthetists); three focus groups with anaesthetists (one national, two regional; 58 anaesthetists); two focus groups with members of the patient organisation Arthritis Care (7 participants); telephone interviews with people on consultant waiting lists from two UK regional centres (15 participants); interviews with Chairs of UK ethics committees (6 individuals); postal surveys of members of the British Association of Surgeons of the Knee (382 surgeons) and members of the British Society of Orthopaedic Anaesthetists (398 anaesthetists); two centre pilot (49 patients assessed).
Results: There was widespread acceptance that evaluation of arthroscopic lavage had to be conducted with a placebo control if scientific rigour was not to be compromised. The choice of placebo surgical procedure (three small incisions) proved easier than the method of anaesthesia (general anaesthesia). General anaesthesia, while an excellent mimic, was more intrusive and raised concerns among some stakeholders and caused extensive discussion with local decision-makers when seeking formal approval for the pilot. Patients were willing to participate in a pilot with a placebo arm; although some patients when allocated to surgery became apprehensive about the possibility of receiving placebo, and withdrew. Placebo surgery was undertaken successfully.
Conclusions: Our study illustrated the opposing and often strongly held opinions about surgical placebos, the ethical issues underpinning this controversy, and the challenges that exist even when ethics committee approval has been granted. It showed that a placebo-controlled trial could be conducted in principle, albeit with difficulty. It also highlighted that not only does a placebo-controlled trial in surgery have to be ethically and scientifically acceptable but that it also must be a feasible course of action. The place of placebo-controlled surgical trials more generally is likely to be limited and require specific circumstances to be met. Suggested criteria are presented.

Eventscapes : visualizing events over time with emotive facets

The scale and dynamicity of social media, and interaction between traditional news sources and online communities, has created challenges to information retrieval approaches. Users may have no clear information need or be unable to express it in the appropriate idiom, requiring instead to be oriented in an unfamiliar domain, to explore and learn. We present a novel data-driven visualization, termed Eventscape, that combines time, visual media, mood, and controversy. Formative evaluation highlights the value of emotive facets for rapid evaluation of mixed news and social media topics, and a role for such visualizations as pre-cursors to deeper search.

Resolving controversies in hip fracture care : the need for large collaborative trials in hip fractures

Summary: Hip fractures are a significant cause of morbidity and mortality worldwide and the burden of disability associated with hip fractures globally vindicates the need for high-quality research to advance the care of patients with hip fractures. Historically, large, multi-centre randomized controlled trials have been rare in the orthopaedic trauma literature. Similar to other medical specialties, orthopaedic research is currently undergoing a paradigm shift from single centre initiatives to larger collaborative groups. This is evident with the establishment of several collaborative groups in Canada, in the United States, and in Europe, which has proven that multi-centre trials can be extremely successful in orthopaedic trauma research.

Despite ever increasing literature on the topic of his fractures, the optimal treatment of hip ftractures remains unknown and controversial. To resolve this controversy large multi-national collaborative randomized controlled trials are required. In 2005, the International Hip Fracture Research Collaborative was officially established following funding from the Canadian Institute of Health Research International Oppurtunity Program with the mandate of resolving controversies in hip fracture management. This manuscript will describe the need, the information, the organization, and the accomplishments to date of the International Hip Fracture Research Collaborative.
