title: Subject(s) matter: a grounded theory of technology teachers’ conceptions of the purpose of teaching technology

authors: Doyle, Andrew

abstract: Technology education internationally has for some time struggled to achieve continuity between what is depicted in policy and curricular documents and the reality of day-to-day practices. With its focus often articulated through the nature of activity students are to engage with, technology teachers are recognised as having significant autonomy in the design and implementation of their practices. From this, it is important to understand teachers’ beliefs about technology education, as their conceptions of the subject will inform practice. As such, this study sought to investigate teachers’ conceptions of the purpose of teaching technology through reflection on their enacted practices. A constructivist grounded theory methodology was employed for the design of the study and analysis of data. According to our analysis, despite similarities between the nature of student activity that teachers designed and implemented, teachers represented the purpose of the subject in different ways. Three different conceptions of the purpose of teaching technology were identified; obtaining knowledge and skills for application, ability to act in a technological way, and ability to think in a technological way. Central to the three conceptions were contentions in the representations of what constituted subject matter knowledge in the subject, and the role that different application cases played in teaching technology. Without consideration and explicit articulation of the purposes for teaching technology, this lack of clarity and differences in rationale for teaching technology are likely to continue.

title: Sulfide-bridged aggregates from the metalloligand [Pt₂(μ-S)₂(PPh₃)₄] and β-diketonate complexes of cobalt(II) and zinc(II)

authors: Bridson, James Hadley

subjects: Zinc complexes

abstract: Reaction of [Pt₂(μ-S)₂(PPh₃)₄] with a range of zinc(II) and cobalt(II) complexes ML₂, where L is a β-diketonate ligand CH₃COCHCOCH₃, PhCOCHCOPh, CF₃COCHCOTh (Th = 2-thienyl)] permits the synthesis of adducts [Pt₂(μ-S)₂(PPh₃)₄M(diketonate)]⁺, isolated as their BPH₄⁻salts in moderate yields. The cobalt and zinc acetylacetonate complexes were characterised by single-crystal X-ray diffraction studies, which reveal isomorphous structures, with tetrahedral heterometal centres.

title: Māori medical student and physician exposure to racism, discrimination, harassment, and bullying

authors: Cormack, Donna

abstract: IMPORTANCE: Discrimination, bullying, and harassment in medicine have been reported internationally, but exposures for Indigenous medical students and physicians, and for racism
specifically, remain less examined.
OBJECTIVE: To examine the prevalence of racism, discrimination, bullying, and harassment for Māori medical students and physicians in New Zealand and associations with demographic and clinical
characteristics.
DESIGN, SETTING, AND PARTICIPANTS: This cross-sectional study used data from an anonymous national survey of Māori medical students and physicians in New Zealand in late 2021 and early 2022.
Data were analyzed from March 2022 to April 2024.
EXPOSURES: Age, gender, marginalized status (ie, in addition to being Māori, belonging to other groups traditionally marginalized or underrepresented in medicine), year of medical school, year of
graduation, and main work role.
MAIN OUTCOMES AND MEASURES: Direct and witnessed racism, discrimination, bullying, and harassment were measured as any experience in the last year and ever. Any exposure to negative
comments about social groups and witnessing discriminatory treatment toward Māori patients or whānau (extended family). Considering leaving medicine, including because of mistreatment, was
measured.
RESULTS: Overall, 205 Māori medical students (median [IQR] age, 23.1 [21.6-24.3] years; 137 [67.2%] women) and 200 physicians (median [IQR] age, 36.6 [30.1-45.3] years; 123 [62.8%] women)
responded. Direct and witnessed exposure to racism (184 students [91.5%]; 176 physicians [90.7%]) and discrimination (176 students [85.9%]; 179 physicians [89.5%]) ever in medical education,
training, or work environments was common. Ever exposure to witnessed and direct bullying (123 students [66.5%]; 150 physicians [89.3%]) and harassment (73 students [39.5%]; 112 physicians
[66.7%]) was also common. Most respondents reported witnessing Māori patients or their whānau being treated badly in clinical settings, in direct interactions (67 students [57.8%]; 112 physicians
[58.9%]) or behind their backs (87 students [75.0%]; 138 physicians [72.6%]). One-quarter of Māori medical students (45 students), and 37.0%of physicians (61 physicians) had considered leaving or taken a break from medicine because of these experiences. Additional marginalized statuses were significantly associated with any direct experience of mistreatment in the last year for students and physicians. Exposure to some forms of mistreatment were also significantly associated with higher likelihood of thinking about leaving or taking a break from medicine for physicians.
CONCLUSIONS AND RELEVANCE: In this study, Māori medical students and physicians reported high exposure to multiple forms of racism, discrimination, bullying, and harassment in medical
education, training, and work environments, requiring an urgent response from medical institutions.
