Abstract For the purpose of the design and certification of inflight icing protection systems for transport and general aviation aircraft, the eventual re-definition/expansion of the icing environment of FAR 25/JAR 25, Appendix C is under consideration. Such a re-definition will be aided by gathering as much inflight icing event data as reasonably possible, from widely-different geographic locations. The results of a 12-month pilot programme of icing event data gathering are presented. Using non-instrumented turboprop aircraft flying upon mid-altitude routine air transport operations, the programme has gathered observational data from across the British Isles and central France. By observing a number of metrics, notably windscreen lower-corner ice impingement limits, against an opposing corner vortex-flow, supported by wing leading edge impingement limits, the observed icing events have been classified as ‘small’, ‘medium’ or ‘large’ droplet. Using the guidance of droplet trajectory modelling, MVD values for the three droplet size bins have been conjectured to be 15, 40 and 80mm. Hence, the ‘large’ droplet category would be in exceedance of FAR/JAR 25, Appendix C. Data sets of 117 winter-season and 55 summer-season icing events have been statistically analysed. As defined above, the data sets include 11 winter and five summer large droplet icing encounters. Icing events included ‘sandpaper’ icing from short-duration ‘large’ droplets, and a singular ridge formation icing event in ‘large’ droplet. The frequency of ‘large’ droplet icing events amounted to 1 in 20 flight hours in winter and 1 in 35 flight hours in summer. These figures reflect ‘large’ droplet icing encounter probabilities perhaps substantially greater than previously considered. The ‘large’ droplet events were quite localised, mean scale-size being about 6nm.

Migration Research

An ethnographic case study approach to understanding women’s actions and reactions to husbands’ emigration—or potential emigration—offers a distinct set of challenges to a U.S.-based researcher.  International migration research in a foreign context likely offers challenges in language, culture, lifestyle, as well as potential gender norm impediments. A mixed methods approach contributed to successfully overcoming barriers through an array of research methods, strategies, and tactics, as well as practicing flexibility in data gathering methods. Even this researcher’s influence on the research was minimized and alleviated, to a degree, through ascertaining common ground with many of the women. Research with the women of San Juan Guelavía, Oaxaca, Mexico offered numerous and constant challenges, each overcome with ensuing rewards.

Practical Recommendations

In March 2020, the UK Research and Innovation announced an emergency call for research to inform policy and practice responses to the COVID-19 pandemic. This call implicitly and explicitly required researchers to work rapidly, remotely and responsively. In this article, we briefly review how rapid response methods developed in health research can be used in other social science fields. After outlining the literature in this area, we use the early stages of our applied research into criminal justice responses to domestic abuse during COVID-19 as a case study to illustrate some of the practical challenges we faced in responding to this rapid funding call. We review our use of and experience with remote research methods and describe how we used and adapted these methods in our research, from data gathering through to transcription and analysis. We reflect on our experiences to date of what it means to be responsive in fast-changing research situations. Finally, we make some practical recommendations for conducting applied research in a ‘nimble’ way to meet the demands of working rapidly, remotely, responsively and, most importantly, responsibly.

The number of family caregivers to individuals with dementia is increasing. Family physicians are often the first point of access to the health care system for individuals with dementia and their caregivers. Caregivers are at an increased risk of developing negative physical, cognitive and affective health problems themselves. Caregivers also describe having unmet needs to help them sustain care in the community. Family physicians are in a unique position to help support caregivers and individuals with dementia, but often struggle with keeping up with best practice dementia service knowledge. The Dementia Wellness Questionnaire was designed to serve as a starting point for discussions between caregivers and family physicians by empowering caregivers to communicate their needs and concerns and to enhance family physicians’ access to specific dementia support information. The DWQ aims to alert physicians of caregiver and patient needs. This pilot study aimed to explore the experiences of physicians and caregivers of people using the Questionnaire in two family medicine clinics in Ontario, Canada. Interviews with physicians and caregivers collected data on their experiences using the DWQ following a 10-month data gathering period. Data was analyzed using content analysis. Results indicated that family physicians may have an improved efficacy in managing dementia by having dementia care case specific guidelines integrated within electronic medical records. By having time-efficient access to tailored supports, family physicians can better address the needs of the caregiver–patient dyad and help support family caregivers in their caregiving role. Caregivers expressed that the Questionnaire helped them remember concerns to bring up with physicians, in order to receive help in a more efficient manner.

This paper reviews the process used to design the construction dewatering system at the Influent Pumping Station at Annacis Island Wastewater Treatment Plant. The design process followed the "observational method," as applied to soil mechanics by K. Terzaghi and set out by R.B. Peck in the Ninth Rankine Lecture. The design was based on a working hypothesis of behaviour anticipated under the most probable conditions identified in the data gathering and assessment program. The sensitivity of the design was evaluated by considering potentially unfavourable conditions evident in the available data. The design development included a review of monitoring feedback obtained during the pumping-well installation, a pumping test, and the dewatering system start-up. The monitoring program and review process are presented.Key words: dewatering, observational method, case study, pumping test.

The purpose of this article is to describe a methodological adventure in the use of the survey technique to investigate shamanism. At the outset I must state my belief that the anthropologist should use structured techniques, if at all, only after he has used unstructured ones. Structured data-gathering is a valuable supplement to, but never a substitute for, unstructured interviewing and observing. This article describes the use of a structured technique as a supplementary means of understanding shamanism, an area which, to my knowledge, has heretofore been studied only by unstructured techniques.

Purpose The purpose of this paper is to examine faculty members’ views about the assessment of world-class university components in Iran’s comprehensive universities. Design/methodology/approach This study adopted a descriptive methodology by using a survey method. The statistical population consisted of 8,548 faculty members of comprehensive universities all over Iran. Considering the large size of the population, the comprehensive universities were categorized into five clusters (North, South, East, West and Center). The authors selected the faculty members from different clusters using Cochran’s formula. A total of 367 faculty members were selected from five clusters. For data gathering, a researcher-designed questionnaire was used. In data analysis, statistical procedures including the Confirmatory Factor Analysis, Kolmogrov-Smirnov test, one-sample t-test, and Friedman test were performed. Findings The findings of the research showed that except for academic freedom, other components of world-class university in Iran’s comprehensive universities were lower than the mean. Practical implications The case study showed how Iran’s comprehensive universities can become world-class universities. The methods of this case study can also be used in other fields. Originality/value This study adds to the knowledge of a world-class universities. Therefore to reach a desired level in comprehensive universities’ preparation for converting to a world-class university, it is essential that the policy makers and organizers of Iran’s higher education system pay greater attention to items such as research motivation, research innovation, research budget increase, authority reduction on various university departments, internet bandwidth increase and laboratory facilities increase.

Purpose This paper aims to explore the nexus between integrated reporting and sustainability embeddedness. It seeks to contribute to a better understanding of the nexus by obtaining in-depth insight from the sensemaking of those in practice. Design/methodology/approach A single exploratory case study design strategy was applied to a leading stock exchange listed company in the property industry in South Africa. Rich qualitative data were gathered by applying multiple data gathering techniques to a diverse group of employees within the case company. Findings This empirical study contributes a metaphor of a cog and chain and nine themes that elucidate employee sensemaking at the nexus. Integrated reporting was found to drive sustainability embeddedness and foster changes within the organisation. The themes offer in-depth insight into how employees made sense of integrated reporting as a driver for sustainability embeddedness. Research limitations/implications The findings emerged from a single case study that operated in a mandatory disclosure context and are therefore not generalisable. The findings reflect the intended outcomes of integrated reporting and further research to explore the unintended outcomes and challenges associated with integrated reporting is suggested. Practical implications The study contributes to a growing practice based agenda by offering a better understanding of how integrated reporting and sustainability are conceptualised and adopted in practice. Social implications The findings offer organisations’ guidance on integrated reporting and sustainability embeddedness adoption which can have vast implications for society and the environment. Originality/value The study responds to gaps in the literature and calls for studies to explore the intersection between integrated reporting and sustainability embeddedness by engaging those in practice.

Smart Mobility

This article examines converging trends in ageing, digitalisation and datafication in the context of mobility and transport. While mobility data are increasingly captured by (public) transport and mobility as a service (MaaS) providers, Internet of Things (IoT) vehicles, apps and so on, the increasing entanglement of mobility and datafication happens unevenly, for example, in relation to age. This is particularly significant in the light of the rise of data-driven policy-making, and its potential impacts on mobility provision for older people. The article highlights new questions for public policy around data gaps and social inclusion and examines them through a UK case study. The results show that old age and mobility is an area with significant gaps in the data available to policy makers. A key recommendation is for commissioning bodies to develop a strategic approach to structured data gathering and analysis that addresses issues of exclusion from smart public service infrastructure.
