Qualitative Research by a Non-Hierarchical Team

In this and subsequent issues, The Qualitative Report will publish eight articles about a journal written by Edward B. Emerson (1805-1834), a younger brother of American philosopher and writer Ralph Waldo Emerson. This introduction will describe the origins of the project, the sources, the process and the outcomes of the collaboration. The authors hope to document and illustrate the richness and value of interdisciplinary qualitative inquiry, while providing specifics of how the Emerson Journal Project evolved. We provide examples to illustrate the characteristics of effective teamwork, but also present the challenges along the way and how they were surmounted. The breadth of the topics in the journal and the range of expertise within the team have resulted in the use of different approaches to examine Emerson’s text. It is the authors’ goal that these essays will enhance the reading of Emerson´s journal, while contributing to the social and historical understanding of the Caribbean

The Edward Bliss Emerson Journal Project: Qualitative Research by a Non-Hierarchical Team

Edward Bliss Emerson (1805-1834), a younger brother of the renowned essayist and poet Ralph Waldo Emerson, lived in the Caribbean for the final three years of his life. His journal and letters are a rich manuscript source for the history of the Danish Virgin Islands (1831-1832) and Puerto Rico (1831-1834). The texts also reflect the contemporary political and cultural situation in the United States, and Edward\u27s search for health, economic independence, intellectual stimulation and metaphysical fulfillment. These writings ignited an intellectual passion in José G. Rigau-Pérez, a physician, medical epidemiologist, and historian in Puerto Rico. Furthering access to these unique resources he produced a digital version of the journal from the Ralph Waldo Emerson Memorial Association deposit at the Houghton Library (Harvard University, Cambridge, Massachusetts) and the letters kept at Houghton Library, the Emerson Family Papers at Massachusetts Historical Society (Boston), and other locations. (See http://edicionesdigitales.info/biblioteca/Emerson.pdf for the full online text of the journal and letters). Dr. José G. Rigau-Pérez also organized a community of scholars who share a sense a common purpose even in the absence of propinquity. The group includes Silvia E. Rabionet, an associate professor in health education at the University of Puerto Rico School of Public Health and Nova Southeastern University College of Pharmacy; Annette B. Ramírez de Arellano, a planner and policy analyst whose work focuses on public health; Wilfredo A. Géigel, a trial lawyer by profession, an independent scholar, member and past president of the Society of Virgin Islands Historians, and Adjunct Professor of History at the University of the Virgin Islands, St. Croix Campus; Raúl Mayo-Santana, an Ad-Honorem Professor at the School of Medicine, University of Puerto Rico; and Alma Simounet, a Professor of English and Linguistics at the University of Puerto Rico. They explore the Emerson journal and letters from multidisciplinary perspectives to bring forth historical, medical, legal, sociological, and geographical insights of the people, times, and places of the mid 1830s in the Caribbean and United States. The work of this talented team resulted in a series of essays we at The Qualitative Report (TQR) are pleased to present as our first book -The Edward Bliss Emerson Journal Project: Qualitative Research by a Non-Hierarchical Team! Under the editorial guidance of TQR Editor Dan Wulff, Dr. Rigau-Pérez and the other members of the team have produced these unique accounts as a transdisciplinary examination of Emerson\u27s world.https://nsuworks.nova.edu/tqr_books/1001/thumbnail.jp

Living with chronic migraine: a qualitative study on female patients' perspectives from a specialised headache clinic in Spain

OBJECTIVES: The aim of this study was to explore the views and experiences of a group of Spanish women suffering from chronic migraine (CM). SETTING: Headache clinic at a university hospital in Madrid (Spain). PARTICIPANTS: Purposeful sampling of patients that attended a specialised headache clinic for the first time between June 2016 and February 2017 was performed. The patients included were females aged 18–65 and with positive diagnoses of CM according to the International Classification of Headache disorders (third edition, beta version), with or without medication overuse. Accordingly, 20 patients participated in the study with a mean age of 38.65 years (SD 13.85). DESIGN: Qualitative phenomenological study. METHODS: Data were collected through in-depth interviews, researchers’ field notes and patients’ drawings. A thematic analysis was performed following appropriate guidelines for qualitative research. RESULTS: Five main themes describing the significance of suffering emerged: (a) the shame of suffering from an invisible condition; (b) treatment: between need, scepticism and fear; (c) looking for physicians’ support and sincerity and fighting misconceptions; (d) limiting the impact on daily life through self-control; and (e) family and work: between understanding and disbelief. The disease is experienced as an invisible process, and the journey to diagnosis can be a long and tortuous one. Drug prescription by the physician is greeted with distrust and scepticism. Patients expect sincerity, support and the involvement of their doctors in relation to their disease. Pain becomes the main focus of the patient’s life, and it requires considerable self-control. The disease has a strong impact in the work and family environment, where the patient may feel misunderstood. CONCLUSIONS: Qualitative research offers insight into the way patients with CM experience their disease and it may be helpful in establishing a more fruitful relationship with these patients

Safety and efficacy of APSA PHYTAFEED® 20,000 GR/L (6-phytase) as a feed additive for chickens for fattening, chickens reared for laying and minor growing poultry species

APSA PHYTAFEED\uae 20,000 GR/L is a preparation of 6-phytase which is presented in solid and liquid forms. This additive is intended to be used as a zootechnical additive in chickens for fattening or reared for laying/breeding and minor poultry species for fattening or reared for laying/breeding. The 6-phytase present in the additive is produced by a genetically modified strain of Komagataella phaffii. The production strain and its recombinant DNA were not detected in intermediate products used to produce the additive. The final products do not trigger a safety concern with regard to the genetic modification. Based on the results obtained in a tolerance study in chickens for fattening and the data from a subchronic oral toxicity study the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) concluded that the additive is safe for chickens for fattening. This conclusion was extended to chickens reared for laying/breeding and extrapolated to all minor poultry species for fattening or reared for laying/breeding. The FEEDAP Panel concluded that the use of APSA PHYTAFEED\uae 20,000 GR/L as a feed additive gives rise to no concern for consumers. The additive, in either form, is not toxic by inhalation or irritant for skin or eyes and it is not a dermal sensitizer, but it is considered a potential respiratory sensitizer. The use of the product as a feed additive is of no concern for the environment. The FEEDAP Panel evaluated three efficacy trials in which the retention of the phosphorus was studied. The data showed that the additive has the potential to improve the retention of phosphorus in the diets in chickens for fattening at 250 U/kg feed. This conclusion was extended to chickens reared for laying/breeding and extrapolated to all minor poultry species for fattening or reared for laying/breeding

Assessment of the application for renewal of the authorisation of PHYZYME® XP 10000 TPT/L (6-phytase) as a feed additive for all avian species and all swine species

PHYZYME\uae XP 10000 TPT/L is a feed additive that contains 6-phytase produced by a genetically modified strain of Schizosaccharomyces pombe. The applicant requested for the renewal of the authorisation for PHYZYME\uae XP 10000 TPT and L to be used as a feed additive for avian species for fattening/laying, weaned piglets, pigs for fattening and sows and for an extension of use to avian species reared for laying/breeding, suckling piglets and minor porcine species. To support the request or the renewal of the authorisation, the applicant provided evidence that the additive in the market complies with the conditions of the authorisation. According to the information provided by the applicant, no new evidence has been identified that would make the FEEDAP Panel reconsider the previous conclusions regarding the safety for the target species, consumer, user and environment. The application for renewal of the authorisation did not include a proposal for amending the conditions of use in those species for which an authorisation exists that would have an impact on the efficacy of the additive. Therefore, there was no need for assessing the efficacy of the additive in the context of the renewal of the authorisation. Regarding the new species/categories, the Panel concluded that the additive is safe and has a potential to be efficacious in avian species reared for laying/breeding at 250 FTU/kg feed and for suckling piglets and minor porcine species at 500 FTU/kg feed

Development of a prototype lateral flow immunoassay (LFI) for the rapid diagnosis of melioidosis.

Burkholderia pseudomallei is a soil-dwelling bacterium and the causative agent of melioidosis. Isolation of B. pseudomallei from clinical samples is the "gold standard" for the diagnosis of melioidosis; results can take 3-7 days to produce. Alternatively, antibody-based tests have low specificity due to a high percentage of seropositive individuals in endemic areas. There is a clear need to develop a rapid point-of-care antigen detection assay for the diagnosis of melioidosis. Previously, we employed In vivo Microbial Antigen Discovery (InMAD) to identify potential B. pseudomallei diagnostic biomarkers. The B. pseudomallei capsular polysaccharide (CPS) and numerous protein antigens were identified as potential candidates. Here, we describe the development of a diagnostic immunoassay based on the detection of CPS. Following production of a CPS-specific monoclonal antibody (mAb), an antigen-capture immunoassay was developed to determine the concentration of CPS within a panel of melioidosis patient serum and urine samples. The same mAb was used to produce a prototype Active Melioidosis Detect Lateral Flow Immunoassay (AMD LFI); the limit of detection of the LFI for CPS is comparable to the antigen-capture immunoassay (∼0.2 ng/ml). The analytical reactivity (inclusivity) of the AMD LFI was 98.7% (76/77) when tested against a large panel of B. pseudomallei isolates. Analytical specificity (cross-reactivity) testing determined that 97.2% of B. pseudomallei near neighbor species (35/36) were not reactive. The non-reactive B. pseudomallei strain and the reactive near neighbor strain can be explained through genetic sequence analysis. Importantly, we show the AMD LFI is capable of detecting CPS in a variety of patient samples. The LFI is currently being evaluated in Thailand and Australia; the focus is to optimize and validate testing procedures on melioidosis patient samples prior to initiation of a large, multisite pre-clinical evaluation

Hairy black holes in theories with massive gravitons

This is a brief survey of the known black hole solutions in the theories of ghost-free bigravity and massive gravity. Various black holes exist in these theories, in particular those supporting a massive graviton hair. However, it seems that solutions which could be astrophysically relevant are the same as in General Relativity, or very close to them. Therefore, the no-hair conjecture essentially applies, and so it would be hard to detect the graviton mass by observing black holes.Comment: References added. 20 pages, 3 figures, based on the talk given at the 7-th Aegean Summer School "Beyond Einstein's theory of gravity", September 201

Safety and efficacy of an essential oil from Elettaria cardamomum (L.) Maton when used as a sensory additive in feed for all animal species

Following a request from the European Commission, the EFSA Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on the safety and efficacy of an essential oil from the seeds of Elettaria cardamomum (L.) Maton when used as a sensory additive for all animal species. Characterisation of the essential oil identified 37 components accounting for > 99% of its composition, with terpineol acetate (> 35%) and 1,8-cineole (> 20%) being the most prevalent compounds. In the absence of toxicological data of the feed additive itself, a component-based approach was applied to assess the safety of the essential oil as a mixture. Based on structural and metabolic similarity, the components of cardamom oil were allocated to seven assessment groups. Assuming the absence of toxicologically relevant interactions among components, dose addition was applied within each assessment group by calculating the combined margin of exposure as a basis for risk characterisation. The FEEDAP Panel concluded that the additive under assessment is safe at the proposed use level of 5 mg/kg in feed for all animal species. A concentration of 5 mg/L water for drinking is considered safe for all animal species. The use of cardamom essential oil in animal feed is considered safe for the consumer. In the absence of studies, the Panel cannot conclude on the safety for the users when handling the additive. The use of the essential oil under assessment in animal production is not expected to pose a risk for the environment. Since the seeds of E. cardamomum and their preparations are recognised to flavour food and their function in feed would be essentially the same, no further demonstration of efficacy is considered necessary. The Panel made a recommendation to limit the content of methyleugenol in the oil

Safety and efficacy of a natural mixture of dolomite plus magnesite and magnesium-phyllosilicates (Fluidol) as feed additive for all animal species

The additive, a natural mixture of dolomite plus magnesite and magnesium-phyllosilicates, is intended to be used as a technological additive (functional groups: anticaking agents) in feedingstuffs for all animal species. The additive is safe in complete feed for dairy cows, piglets and pigs for fattening at a maximum concentration of 20,000 mg/kg. No conclusions can be drawn for all the other animal species/categories. The additive is not genotoxic. As the additive is essentially not absorbed from the gut lumen, the Panel on Additives and Products or Substances used in Animal Feed considers that use of the additive in animal nutrition is safe for consumers of food products from animals fed diets containing the additive. The additive is not an irritant to the eyes and the skin, it is not a skin sensitiser and it is of low toxicity by the inhalation route. The components of the additive (dolomite, magnesite, talc and chlorite) are natural constituents of soil. Consequently, the use of the additive in animal nutrition will not pose a risk to the environment. The additive is effective as an anticaking agent at a minimum inclusion level of 5,000 mg/kg feed
