A total of 1095 fish were analysed, representing 15 species. In total 1384 particles of plastic debris were recovered from the gastrointestinal tracts of 552 specimens belonging to 13 species, and all consisted of threads, the majority of which were small microplastics (0.23 to 1.89), followed by large microplastics (2.07 to 4.49), and few mesoplastics (5.4 to 19.86). Plastic particles were identified using ATR-FTIR spectroscopy. The mean frequency of occurrence of plastics in the gastrointestinal tracts of fishes from this system was 50.5%, which is higher than frequencies reported in similar systems in other areas. The polymers identified by ATR-FTIR were polyamide (51.2%), polyethylene (36.6%), polypropylene (7.3%), and polyacrylic (4.9%). These results show the first evidence of plastic contamination for estuarine biota in the Gulf of California. Despite a worldwide emphasis in nursing codes of practice that state nurses must uphold professional values to be caring and compassionate, evidence continues to emerge of poor-quality care standards. Existing literature attests to a tendency to deteriorating caring values as students' progress through their nursing programme. In response, one university in England exposed pre-registration nursing students to a values-based curriculum which embedded Todres et al.'s (2009) Humanising Values Framework. This paper describes the later stages of a co-operative inquiry, where students as participants explore their evolving values around person-centred approaches to care as they engaged with clinical practice. Data were collected between 2013 and 2016. Findings reveal how students developed their
