title: Second look – second think: a fresh look at video to support dialogic feedback in peer coaching

authors: Charteris, Jennifer

subjects: collaborative inquiry

abstract: This case study, concerning peer coaching for sustainable professional practice, utilised video to enable teachers 'deep learning' during peer coaching sessions. While the use of video is not a new tool for continuing professional development, this research employs a fresh way of using it. Teachers reflected on their learning process by watching video footage filmed during group peer coaching sessions. The study explores how this reflection with peers influenced the teachers' thinking and decision-making. Findings indicated that teacher participants were able to 'see' themselves thinking, becoming more explicitly aware of their peer coaching role and their own professional learning processes. This paper links strongly to the theme of this special, issue advancing that the use of video can enable teachers a unique opportunity to review and reflect on their positioning in their professional learning. The research recommends ongoing exploration of practices that afford teachers opportunities to develop metacognitive awareness and an agentic role in their own learning

title: Waste-to-Energy: Solar pyrolysis of sludge, as a part of global solid waste issue, to produce oil. Initial trial to design a household solar pyrolysis device

authors: Hasan, Sohaib

subjects: Solid waste management

abstract: Daily, huge amounts of solid waste are produced around the world with 70% increase rate. Municipal solid waste (MSW) including sewage sludge is the main waste generated in cities and towns. Proper waste management approaches are urgently needed. Despite numerous social and technical approaches were presented, this paper aims to employ plenty of solar energy specifically in the Middle East into a waste-to energy solution. By using solar pyrolysis technology, this study aims to present a solar powered design to convert sludge into oil. This design can be easily upgraded to a household device as a household waste management approach. Like other thermochemical reactions, solar pyrolysis of sludge produces bio-oil which has a reasonable calorific value making this technology is useful as a fuel source. However, unlike others, solar pyrolysis has low operation cost and not dependent on fossil fuel. Although this device is designed only for sludge, it can be used also to convert all kinds of domestic wastes including waste oils, plastics, rubbers, and municipality solid waste (MSW) into energy and oil. This research illustrates a novel design for a dryer that produce “a slude flacks” by using solar energy. Factors such as feasibility, continuity, productivity, drying time, and quality of the yield were considered in this design. A rotational dryer with ɸ 1m and 1m length was modelled by Solidwork software application to dry wet sludge of 75% water content. Different types of solar concentrators were employed to maximize productivity and minimize cost and area. However, the average daily production of this dryer per 8 sunny working hours was around 51.87 litters of bio-oil, 31.78 Kg bio-char, and 58.785 Kg syngas. The best results were measured when the average mass flow into the reactor is 21 kg/hr. This study highlights solar pyrolysis efficiency in waste management. This research aims to develop a solar-powered system, using the sludge as fuel to generate energy. The experiments were done at Waikato University, NZ. As known, Waikato district is wet and cloudy most days in comparison to those countries on the Sunbelt such as Jordan. Interestingly, figures show that solar pyrolysis of sludge has high potential in Jordan and Middle East countries in term of plenty of solar energy and sunny days. However, although solar pyrolysis can be described as an affordable eco friendly technology that can be used directly by householders as a source of energy, its viability and feasibility in Middle East still need further study.

title: Nobody knows me even though I’m always there: Why Māori men do exist - in all the wrong places

authors: Stanley, Paul

subjects: Maori

abstract: In the study of psychology, Māori men are often only seen as the perpetrators of the problems. There is very little focus on finding solutions for Māori men, with Māori men. In the top eight causes of death for Māori males aged 15 to 24 are car crashes, homicide, and suicide. With respect to car crashes, there is a close link between alcohol-related car crashes and suicide. As a nation, we should be concerned with all of the above issues, as each of them is preventable. Invariably, we fail see the deaths of these young men as warning signs of much wider issues about why they wanted to die, or why they felt the need to kill someone close to themselves. The argument tendered in this paper is that the same way in which Māori as a group have been researched, as being “the problem”, equally applies to the way in which Māori men have continued to be have been researched: Māori men are only ever portrayed as “the problem” and are never portrayed as part of a solution subjected to this process as well. The lyrics of a well known song by UB40, One in Ten, exemplify this notion of being unknown, even though Māori men do exist in Aotearoa.
