ABSTRACT
This chapter discusses the experience of three graduate students of social work enrolled in field instruction during the first semester that was restructured to be managed remotely, due to the restrictions of the COVID-19 community quarantine in the Philippines. Specifically, the researcher examined the integrative reports and reflexive notes of the students and faculty supervisors, and audio/video recordings of the department's field sharing of experiences. Comparison of the data from the proposed models of practice submitted by the graduate students revealed different knowledge sources used by the students in evaluating the gaps in practice in their respective agencies. The proposed models of the graduate reflected the combination of knowledge shared by the different stakeholders, (organizations, clients, faculty supervisors, agency supervisors), the application of theories and perspectives in social work and other disciplines, and the insights and strategies gleaned from innovative practice. This knowledge creation is vital toward the remaking of social work for the future. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2022.
ABSTRACT
In this study, the temporal evolution and sources of water-soluble organic carbon (WSOC) in submicron particles at an urban background site in Elche (Spain) were investigated. Measurements of PM1 (N = 200) were carried out over one year (2021). Samples were analysed for organic carbon (OC), elemental carbon (EC), WSOC, levoglucosan, elements and major ions. A positive matrix factorization (PMF) analysis was performed in order to identify the sources of WSOC on an annual and a monthly basis. During the study period, traffic restrictions due to COVID-19 led to lower concentrations of PM1 and carbonaceous compounds than expected. The WSOC annual average mass concentration was 0.95 mugm-3, with maximum values during the colder months. The apportionment results indicate that the biomass burning (BB) source contributed 30.63% to WSOC levels, road traffic (RT) accounted for 23.90% of the WSOC, while the contribution of a source related to secondary organic aerosol formation (ammonium sulfate-AS) was 33.80%. Minor sources of WSOC were: soil dust (SD) and secondary nitrate (SN), which contributed 7.44% and 4.22%, respectively, to WSOC concentrations. The WSOC/OC ratio did not exhibit significant variations during the study period, since source contributions were similar for WSOC and OC. The highest values of this ratio were recorded in summer, due to the higher contribution from the AS source to WSOC concentrations.Copyright © 2023 The Authors
ABSTRACT
Introduction: The health context with COVID-19 pandemic has led to fast development of many vaccines against the SarS-Cov-2 virus. Four of them are currently available in France and contain polyethylene glycol (PEG) or polysorbate 80 as excipients, already described as causing anaphylaxis. French recommendations have been suggested by allergology authorities and proposed a course of action in the event of a suspected allergy to these vaccines. Thus, allergies to excipients were the only contraindication to COVID-19 vaccination. Our main objective was to determine the impact of these allergology vaccine recommendations on the management of these patients. Our secondary objective was to determine prevalence of true allergies to these vaccines. Materials and methods: We conducted a unicentric descriptive retrospective study with all patients over 18 years of age referred for an allergological opinion before or after an injection of one of the anti-COVID-19 vaccines. Nineteen patients were classified into different interest groups, based on french recommendations. Results: The vast majority of patients did not require a pre-vaccination allergological assessment. Indeed, only 25 patients received skin tests prior to vaccination. The rest of patients were able to be vaccinated without allergological assessment. Patients not vaccinated due to allergy to excipients represent less than 1% of the population (n = 3/320). Conclusion: French recommendations made it possible to vaccinate the vast majority of patients included in our study. Allergy to PEG, polysorbate or their derivatives, the only contraindication to anti-COVID vaccination, according to the recommendations of February 2021, remains rare. Today, several authors propose tolerance inductions allowing the vaccination of patients allergic to PEGs or their derivatives with good tolerance.
