title: Climate change is here:  Teachers’ and students’ perceptions about education for It

authors: Bevins, Patricia Anne

subjects: Climate change

abstract: Climate change is the greatest threat humans have ever faced. The unprecedented anthropogenic activity impacting on the environment is having catastrophic effects across the globe and could continue for thousands of years. Mitigation to prevent further environmental harm and adaptation to the already-changing conditions are essential strategies in addressing climate change and, therefore, education for these strategies is imperative. Educators have an opportunity to prepare our learners with the knowledge and skills they will need to combat the impacts and effects of climate change. Climate change education offers young people a chance to develop their knowledge, critical and creative thinking and problem-solving skills while building their resilience and adaptive capacity to act in this crisis. But are our young people getting these learning opportunities?
This was an interpretive study that focused on the perceptions of climate change and climate change education of students, teachers and leaders at a secondary school in the Waikato region of New Zealand. A mix of quantitative and qualitative data was gathered by using an on-line questionnaire and focus groups with students and semi-structured interviews with their teachers and leaders. The data were divided into four sections: beliefs, knowledge, attitudes and actions for both the student data and the teachers’ and leaders’ data, and were thematically analysed using NVivo. 
The data clearly showed in this study that the students were worried about how climate change was going to affect their future lives and the lives of the people closest to them and most wanted to change their behaviour and take action to try and reduce the effects of a changing climate. In order to do this, the students wanted to learn more about climate change, raise their awareness, and the awareness in their community, so that everybody could be prepared for the changing climate. The findings indicated that the teachers all agreed that climate change education is important for students and wanted to know more about climate change so they could inform their students about climate change through education. The leaders indicated that it is vital that the students’ are thoroughly prepared for the changing climate and a change in behaviour, but they also felt that the teachers needed to be supported as well, and not just those teaching about climate change, but to make sure everyone is prepared for an uncertain future. 
This study recommends the Ministry of Education to firstly, consider how climate change education can be made available to all children and young people, and then to provide guidance on how educators in schools and teacher education throughout New Zealand could teach about climate change to all our learners.

title: Continuing professional development systems for medical physicists: A global survey and analysis

authors: Round, W. Howell

subjects: continuing professional development

abstract: Continuing professional development (CPD) and continuing professional education (CPE) are seen as being necessary for medical physicists to ensure that they are up-to-date with current clinical practice. CPD is more than just continuing professional education, but can include research publication, working group contribution, thesis examination and many other activities. A systematic way of assessing and recording such activities that a medical physicist undertakes is used in a number of countries. This can be used for certification and licensing renewal purposes. Such systems are used in 27 countries, but they should be implemented in all countries where clinical medical physicists are employed.
A survey of the CPD systems that are currently operated around the world is presented. In general they are quite similar although there are a few countries that have CPD systems that differ significantly from the others in many respects. Generally they ensure that medical physicists are kept up-to-date, although there are some that clearly will fail to achieve that.
An analysis of what is required to construct a useful medical physics CPD system is made. Finally, the need for medical physicist professional organizations to cooperate and share in the production and distribution of CPD and CPE materials is emphasized.

title: Evaluating the effects of invasive brown bullhead catfish (Ameiurus nebulosus) on kōura (freshwater crayfish, Paranephrops planifrons) in Lake Rotoiti

authors: Francis, Laura Beverley

subjects: catfish

abstract: Brown bullhead catfish (Ameiurus nebulosus) are opportunistic carnivores native to North America and were first detected in Te Weta Bay, Lake Rotoiti, in March 2016. A cordon was placed across the bay to try and contain catfish, but they had already established populations elsewhere. Spread of catfish in the lake raised concern for resident populations of freshwater crayfish or kōura (Paranephrops planifrons), which are of ecological and cultural significance to Māori. Given the limited knowledge of the potential impacts of catfish on native biota, this thesis aims to evaluate the effects of catfish on kōura in Lake Rotoiti. To do this, Bay of Plenty Regional Council (BOPRC) routine fyke netting data was used to explore species trends and relationships. A habitat survey was also conducted using whakaweku (bracken fern bundles) and fyke nets, to generate data on species’ habitat preferences and kōura metrics (e.g., sizes and sex ratios). In addition to fishing, kōura and catfish stomachs were dissected to determine diet. Potential food items of catfish were also collected for stable isotope analysis to estimate dietary overlap between catfish and kōura, and long-term resource acquisition. 

Routine BOPRC fyke netting results indicated that kōura catch per unit effort (CPUE) has declined in Lake Rotoiti, with mean catch rates dropping from 10.6 kōura net-1 night-1 in 2016 to 4.2 kōura net-1 night-1 in 2018. Over the same period, catfish CPUE has increased in the lake, with the highest catch rates in Te Weta Bay, where mean catch rates have increased from 1.1 catfish net-1 night-1 in 2016 to 63.7 catfish net-1 night-1 in 2018. Catfish catch rates were negatively associated with catch rates of kōura (r = −0.180). Mean catfish density also had a significant effect on kōura catch rates, with significantly more kōura being caught at sites without catfish. The negative association between catfish and kōura could be due to catfish eating or competing with kōura, or their differing habitat preferences. Catfish were positively associated with sites that are weedy or muddy and kōura were negatively associated with muddy habitats and were positively associated with rocky habitats. Whakaweku set at shallow depths <1 m in the lake littoral zone were ineffective at catching kōura during the habitat survey. 

Catfish diet consisted largely of chironomid larvae (Chironomidae), detritus, common bullies (Gobiomorphus cotidianus), and to a lesser extent kōura. Kōura were found in 12% of large catfish (>200 mm fork length; FL) stomachs analysed and contributed 5% volumetrically to large catfish diet. Unfortunately, the contribution of kōura to catfish diet could not be established using stable isotopes because isotopic signatures of kōura and bullies were too close to differentiate. Kōura diet consisted primarily of animal remains (common bullies and invertebrates) and detritus. Stable isotopes of carbon and nitrogen revealed that diets of kōura and catfish overlapped, with kōura sharing more of their diet with catfish than vice versa, likely reflecting catfish’s broad diet. This study suggests that catfish are responsible for the recent decline in kōura CPUE in Lake Rotoiti and that catfish are directly and indirectly affecting kōura through predation and competition for shared food resources.
