ABSTRACT. The influence of predators on populations of the sea urchin Evechlnus chlorot~cus in northeastern New Zealand was investigated by companng densltles, population size structure, and crevice occupancy in manne reserve ('protected') and exploited locality palrs There was no overall dlfference in sea urchin density between protected and exploited localities, but population slze structures were generally more bimodal in the protected localities Size-related patterns of crevice occupancy d~d not vary consistently between protected and exploited locahty pairs The effects of protection were most pronounced in the Cape Rodney -Okakan Polnt (CROP) Manne Reserve, where relative to the adjacent fished area (1) sea urchln densities weie -3 times lower, (2) slze structures were more bimodal and (3) sea urchlns remained crevice-bound to larger slzes (-40 mm test diameter) Sea urchin transplant experments showed hlgher losses of 30 to 40 mm test dlameter E chorotjcus at a protected locality than a fished locahty Tests of adult sea urchins were heavler at sites in the reserve relative to the fished reference area We suggest that predatory flshes, which were larger and more numerous in the reserve, were the cause of the differences A strong bimodal size structure persisted and density declined over 10 yr at one site in CROP Manne Reserve We suggest that generahs~ng from reserve studles to exploited areas may lead to erroneous conclusions

Objective: We explored Australian workers' experiences of nonstandard employment, how it related to health and wellbeing, and the role that Bourdieu's forms of capital (cultural, economic and social resources) played in underpinning workers' agency. Methods:Qualitative data from semistructured interviews with 32 causal workers were analysed based on framework analysis. Results: Most participants were 'deliberate casuals' who had chosen casual over permanent employment, with half of that group naming improved health and wellbeing as motivation. Those with greater access to capital felt more able to exercise choice, whereas those with fewer capital resources felt constrained to be casual. Gendered structures and labour market dynamics were also significant in shaping agency. Conclusions:Access to capital and a buoyant labour market underpinned workers' agency in Australia, enabling some to gain health and wellbeing benefits from nonstandard employment.

Adolescents and young adults (aged 15–25 years) diagnosed with cancer have unique medical and psychosocial experiences and care needs, distinct from those of paediatric and older adult patients. Since 2011, the Australian Youth Cancer Services have provided developmentally appropriate, multidisciplinary and comprehensive care to these young patients, facilitated by national service coordination and activity data collection and monitoring. This paper reports on how the Youth Cancer Services have conceptualised and delivered quality youth cancer care in four priority areas: clinical trial participation, oncofertility, psychosocial care and survivorship. National activity data collected by the Youth Cancer Services between 2016–17 and 2019–20 are used to illustrate how service monitoring processes have facilitated improvements in coordination and accountability across multiple indicators of quality youth cancer care, including clinical trial participation, access to fertility information and preservation, psychosocial screening and care and the transition from active treatment to survivorship. Accounts of both service delivery and monitoring and evaluation processes within the Australian Youth Cancer Services provide an exemplar of how coordinated initiatives may be employed to deliver, monitor and improve quality cancer care for adolescents and young adults.

Background: Precarious employment has been associated with poor health, but the
