Blurring Boundaries: Negotiating Researchers’ Positionality and Identities in Digital Qualitative Research

This contribution discusses a series of methodological, ethical, and ontological challenges encountered by the authors during a series of recent socio-criminological studies based on digital ethnography and investigating sensitive and emotive issues. Particularly, we will discuss the practical difficulties we encountered in navigating several increasingly blurred boundaries, such as those among: (1) the researchers’ private and public academic/personal selves online; (2) the shifting of the traditional power imbalances between the researcher and research participants; (3) concerns over impartiality in research; and (4) elements of ethnography and autoethnography becoming obfuscated. We consider these dilemmas in the context of the pervasiveness of digital technologies within contemporary social life, such that we as researchers are always simultaneously on and offline, with our studies at risk of becoming all-consuming and encroaching on all areas of our lives. We will see how these blurred boundaries entail an inescapable continuous negotiation of researcher identity and positionality, and some of their practical consequences. We aim to encourage further discussion about these novel challenges faced whilst undertaking online research, and re-examination of the related ethical principles regarding these contexts

Direct contacts with potential interviewees when carrying out online ethnography on controversial and polarized topics: a loophole in ethics guidelines.

Direct contacts with research participants in online ethnography are an important tool to better understand complex social dynamics in cyberspace. The current ethical approaches guiding academic research, however, can be problematic in this regard, creating unintended tensions leading to potential research biases as well as safety and wellbeing issues for researchers working on controversial and polarized topics. The onus, we argue, ends up being on academics to protect and separate the personal information available about them online from the professional, trying to overcome what seems to be an inevitable blurring of boundaries. In this research note, we present two case studies to highlight what we perceive as a loophole in current ethics guidelines

Family Planning Decision Making in People With Multiple Sclerosis

Introduction: The majority of people diagnosed with MS are of childbearing or child fathering age, therefore family planning is an important issue for both women and men with MS. Fertility and the course of pregnancy are not affected by MS; however, people with MS (pwMS) may have concerns that there will be a greater risk of complications to the mother and/or adverse pregnancy outcomes either due to the disease or to ongoing medication. This survey aimed to understand family planning decision making in pwMS and related unmet educational needs. Methods: A total of 332 pwMS across the USA, UK, France, Germany, Italy, and Spain were recruited from a specialist patient panel agency to participate in a smartphone-enabled standing panel. The 80-question survey focussed on decision making and information sources for pwMS regarding family planning, as well as behavior during and after pregnancy. Male patients with MS did not respond to specific questions on pregnancy. Survey results were directly compared with the 2016 US and 2010 UN census data. Results: pwMS were more likely to have no children than the general population, particularly in the subgroup of patients aged 36–45 years. A total of 56% of pwMS reported that the disease affected, with different degrees of impact, their family planning decision making. Of these, 21% significantly changed their plans for timing of pregnancy and the number of children, and 14% decided against having children. Participants indicated that healthcare professionals were the primary source of information on family planning (81% of responses). The timing of planned pregnancy was not considered when selecting treatment by 78% of participants. Conclusion: MS was found to significantly impact family planning decision making, with pwMS significantly less likely to have children in comparison with the general population

To App or Not to App? Understanding public resistance to COVID-19 digital contact tracing and its criminological relevance

In the context of the COVID-19 pandemic, digital contact tracing has been developed and promoted in many countries as a valuable tool to help the fight against the virus, allowing health authorities to react quickly and limit contagion. Very often, however, these tracing apps have faced public resistance, making their use relatively sparse and ineffective. Our study relies on an interdisciplinary approach that brings together criminological and computational expertise to consider the key social dynamics underlying people’s resistance to using the NHS contact-tracing app in England and Wales. The present study analyses a large Twitter dataset to investigate interactions between relevant user accounts and identify the main narrative frames (lack of trust and negative liberties) and mechanisms (polluted information, conspiratorial thinking and reactance) to explain resistance towards use of the NHS contact-tracing app. Our study builds on concepts of User eXperience (UX) and algorithm aversion and demonstrates the relevance of these elements to the key criminological problem of resistance to official technologies

Right phrenic nerve palsy following transcatheter radiofrequency current atrial fibrillation ablation: Case report

Phrenic nerve palsy (PNP) is a well-known complication of cardiac surgery or jugular/subclavian vein catheterization, presenting with cough, hiccups, dyspnoea/shortness of breath and, in some cases, ventilatory failure. Rarely, PNP is a complication of transcatheter radiofrequency ablation for atrial fibrillation. This report describes the case of a 72-year-old woman with a 2-year history of recurrent paroxysmal atrial fibrillation associated with occasional palpitations and shortness of breath who underwent routine transcatheter radiofrequency ablation. Three days after the procedure, the patient developed shortness of breath and progressive dyspnoea. Motor nerve conduction showed the absence of the right phrenic nerve compound motor action potential compared with the normal left side confirming the diagnosis of a right phrenic nerve palsy. This current case demonstrated the importance of undertaking an electrophysiological evaluation of phrenic nerve conduction after transcatheter radiofrequency ablation in patients presenting with palpitations and shortness of breath even if present a few days after the procedure

Chemical fate and genotoxic risk associated with hypochlorite treatment of nicotine

Nicotine, the main alkaloid of tobacco, is a non-prescription drug to which all members of a tobacco-smoking society are exposed either through direct smoke inhalation or through second-hand passive 'smoking'. Nicotine is also commercially available in some pharmaceutical products and is used worldwide as a botanical insecticide in agriculture. Nicotine dynamics in indoor and outdoor environments as well as the human excretions and the manufacturing process are responsible for its entry in the environment through municipal and industrial wastewater discharges. The presence of nicotine in surface and ground waters points out that it survives a conventional treatment process and persists in potable-water supplies. Complete removal of nicotine is instead reported when additional chlorination steps are used. In this paper a simulation of STP chlorination of nicotine and a genotoxic evaluation of its main degradation products are reported. Under laboratory conditions removal of nicotine seems not to be due to mineralization but to transformation in oxidized and chlorinated products. The by-products have been isolated after fractionation by diverse chromatographic procedures and their structures determined using mass spectrometry and H-1 and C-13 NMR spectroscopy. Preliminary genotoxic SOS Chromotests with Escherichia coil PQ37 evidence no toxicity of the products. (C) 2012 Elsevier B.V. All rights reserved

Peculiarities in the structure - properties relationship of epoxy-silica hybrids with highly organic siloxane domains

Epoxy-silica hybrids were produced from a diglycidyl ether of bisphenol-A resin using Jeffamine 230 hardener with a two-step in situ generation of siloxane domains. The siloxane component was obtained by hydrolysis and condensation of a mixture of γ-glycidoxypropyl-trimethoxysilane and tetraethoxysilane, which was added to the epoxy resin after removal of the formed alcohols and water. The morphological structure of the hybrids was examined by TEM, SAXS and WAXS analysis, and confirmation of the identified co-continuity of the constitutive phases for nominal silica contents greater than 18%wt was obtained by TGA and DMA analysis. While the loss modulus was found to increase monotonically over the entire range of siloxane content, the glass transition temperature exhibited a stepwise increase upon reaching the conditions for phase co-continuity. Molecular dynamics simulations were used to produce model structures for silsequioxanes cage-like structures, as main constituents of the siloxane phase. The predicted interdomain distance between the silsequioxane structures was in agreement with the SAXS experimental data

Hybrid Graphenene Oxide/Cellulose Nanofillers to Enhance Mechanical and Barrier Properties of Chitosan-Based Composites

Chitosan-based hybrid nanocomposites, containing cellulose nanocrystals (CNCs), graphene oxide (GO), and borate as crosslinking agents, were successfully prepared by solution-casting technique. The synergistic effect of the two fillers, and the role of the cross-linker, in enhancing the structural and functional properties of the chitosan polymer, was investigated. XPS results confirm the chemical interaction between borate ions and hydroxyl groups of chitosan, GO, and CNCs. The morphological characterization shows that the GO sheets are oriented along the casting surface, whereas the CNC particles are homogenously distributed in the sample. Results of tensile tests reveal that the presence of graphene oxide enhances the elastic modulus, tensile strength, elongation at break, and toughness of chitosan, while cellulose and borate induce an increase in the elastic modulus and stress at the yield point. In particular, the borate-crosslinked chitosan-based sample containing 0.5 wt% of GO and 0.5 wt% of CNCs shows an elongation at a break value of 30.2% and a toughness value of 988 J*m−3 which are improved by 124% and 216%, respectively, compared with the pristine chitosan. Moreover, the water permeability results show that the presence of graphene oxide slightly increases the water barrier properties, whereas the borate and cellulose nanocrystals significantly reduce the water vapor permeability of the polymer by about 50%. Thus, by modulating the content of the two reinforcing fillers, it is possible to obtain chitosan-based nanocomposites with enhanced mechanical and water barrier properties which can be potentially used in various applications such as food and electronic packaging
