Different Cultures

Some in the social sciences argue that the same logic applies to both qualitative and quantitative research methods. This book demonstrates that these two paradigms constitute different cultures, each internally coherent yet marked by contrasting norms, practices, and toolkits. The book identifies and discusses major differences between these two traditions that touch nearly every aspect of social science research, including design, goals, causal effects and models, concepts and measurement, data analysis, and case selection. Although focused on the differences between qualitative and quantitative research, the book also seeks to promote toleration, exchange, and learning by enabling scholars to think beyond their own culture and see an alternative scientific worldview. The book is written in an easily accessible style and features a host of real-world examples to illustrate methodological points.

AbstractComputer and Information Security (CIS) is usually approached adopting a technology-centric viewpoint, where the human components of sociotechnical systems are generally considered as their weakest part, with little consideration for the end users’ cognitive characteristics, needs and motivations. This paper presents a holistic/Human Factors (HF) approach, where the individual, organisational and technological factors are investigated in pilot healthcare organisations to show how HF vulnerabilities may impact on cybersecurity risks. An overview of current challenges in relation to cybersecurity is first provided, followed by the presentation of an integrated top–down and bottom–up methodology using qualitative and quantitative research methods to assess the level of maturity of the pilot organisations with respect to their capability to face and tackle cyber threats and attacks. This approach adopts a user-centred perspective, involving both the organisations’ management and employees, The results show that a better cyber-security culture does not always correspond with more rule compliant behaviour. In addition, conflicts among cybersecurity rules and procedures may trigger human vulnerabilities. In conclusion, the integration of traditional technical solutions with guidelines to enhance CIS systems by leveraging HF in cybersecurity may lead to the adoption of non-technical countermeasures (such as user awareness) for a comprehensive and holistic way to manage cyber security in organisations.

This research focuses on the design, construction, and validation of a questionnaire that seeks to analyse the perception of the landscape amongst undergraduates studying for a Degree in Primary School Teaching at Salamanca University. The process has involved using both qualitative and quantitative techniques to test the content’s validity and the construct’s reliability and suitability through the participation of a panel of expert judges and a sample of 432 subjects. This has been followed by the introduction of an exploratory factor analysis (EFA) of the data provided by the cohort that has led to a study of the questionnaire’s core characteristics, a reduction in its size, and the validation of its pertinence.

Mixed methods reviews offer an excellent approach to synthesizing qualitative and quantitative evidence to generate more robust implications for practice, research, and policymaking. There are limited guidance and practical examples concerning the methods for adequately synthesizing qualitative and quantitative research findings in mixed reviews. This paper aims to illustrate the application and use of joint displays for qualitative and quantitative synthesis in mixed methods reviews. We used joint displays to synthesize and integrate qualitative and quantitative research findings in a segregated mixed methods review about male nursing students' challenges and experiences. In total, 36 qualitative, six quantitative, and one mixed-methods study was appraised and synthesized in the review. First, the qualitative and quantitative findings were analyzed and synthesized separately. The synthesized findings were integrated through tabular and visual joint displays at two levels of integration. At the first level, a statistics theme display was developed to compare the synthesized qualitative and quantitative findings and the number of studies from which the findings were generated. At the second level, the synthesized qualitative and quantitative findings supported by each other were integrated to identify confirmed, discordant, and expanded inferences using generalizing theme display. The use of two displays allowed in a robust and comprehensive synthesis of studies. Joint displays could serve as an excellent method for rigorous and transparent synthesis of qualitative and quantitative findings and the generation of adequate and relevant inferences in mixed methods reviews.

Rapid measurement of glomerular filtration rate (GFR) by an inulin single-bolus technique would be useful, but its accuracy has been questioned. We hypothesized that reported inaccuracies reflect the use of inappropriate mathematical models. GFR was measured in 14 intact and 5 unilaterally nephrectomized conscious male Sprague-Dawley rats (mean weight 368 ± 12 g) by both single-bolus (25 mg/kg) and constant-infusion techniques (0.693 mg ⋅ kg−1 ⋅ min−1). The temporal decline in plasma inulin concentration was analyzed through biexponential curve fitting, which accounted for renal inulin loss before complete vascular and interstitial mixing. We compared our mathematical model based on empirical rationale with those of other investigators whose studies suggest inaccuracy of single-bolus methods. Our mathematical model yielded GFR values by single bolus that agreed with those obtained by constant infusion [slope = 0.94 ± 0.16 (SE); y intercept = 0.23 ± 0.64; r = 0.82]. In comparison to the data obtained by constant inulin infusion, this method yielded a very small bias of −0.0041 ± 0.19 ml/min. Two previously reported models yielded unsatisfactory values (slope = 1.46 ± 0.34, y intercept = 0.47 ± 1.5, r = 0.72; and slope = 0.17 ± 1.26, y intercept = 17.15 ± 5.14, r = 0.03). The biases obtained by using these methods were −2.21 ± 0.42 and −13.90 ± 1.44 ml/min, respectively. The data indicate that when appropriate mathematical models are used, inulin clearance after single-bolus delivery can be used to measure GFR equivalent to that obtained by constant infusion of inulin. Attempts to use methods of analysis for simplicity or expediency can result in unacceptable measurements relative to the clinical range of values seen.

Twin Models

The theoretical relationship between the distribution of a given trait in a population of twin pairs and several genetic parameters has been examined. In particular, a series of mathematical models has been worked out, that, when applied to a twin population, nonselected for the occurrence of a given trait and nondiagnosed as to zygosity, leads to an estimate of:1) The MZ: DZ ratio in the population;2) The frequency of the genotype responsible for a given trait;3) The probability of manifestation of the trait;4) The value of epistatic factors.A further mathematical model affords the estimate of linkage in the hypothesis of simultaneous recording of more than one trait.
