Technological literacy reconsidered: a model for enactment
The final publication is available at: http://link.springer.com/article/10.1007%2Fs10798-009-9108-6.This paper presents a model to describe technological literacy as enacted by individuals in the course of shaping their lives and the world around them. The model has two interrelated facets – the potential for and enactment of technological literacy – where enactment and potential mutually constitute each other. This potential is made up of knowledge of a particular situation, personal engagement with a situation, and social engagement in the world. Enactment requires a particular set of competencies in action, which together helps shape the situation: recognizing needs; articulating problems; contributing towards the technological process; and analysing consequences. The implications of this model for technological literacy in the context of the individual and society, and the role of technology education in developing technological literacy, are discussed
An instrument to determine the technological literacy levels of upper secondary school students
In this article, an instrument for assessing upper secondary school students’
levels of technological literacy is presented. The items making up the instrument emerged
from a previous study that employed a phenomenographic research approach to explore
students’ conceptions of technology in terms of their understanding of the nature of
technology and their interaction with technological artefacts. The instrument was validated
through administration to 1,245 students on completion of their 12 years of formal
schooling. A factor analysis was conducted on the data and Cronbach alpha reliability coefficients
determined. The results show that a five-dimension factor structure (namely,
artefact, process, direction/instruction, tinkering, and engagement) strongly supported the
dimensions as developed during the original phenomenographic study. The Cronbach
alpha reliability co-efficient of each dimension was satisfactory. Based on these findings,
the instrument has been shown to be valid and reliable and can be used with confidence
Convalescent plasma in patients admitted to hospital with COVID-19 (RECOVERY): a randomised controlled, open-label, platform trial
Background:
Many patients with COVID-19 have been treated with plasma containing anti-SARS-CoV-2 antibodies. We aimed to evaluate the safety and efficacy of convalescent plasma therapy in patients admitted to hospital with COVID-19.
Methods:
This randomised, controlled, open-label, platform trial (Randomised Evaluation of COVID-19 Therapy [RECOVERY]) is assessing several possible treatments in patients hospitalised with COVID-19 in the UK. The trial is underway at 177 NHS hospitals from across the UK. Eligible and consenting patients were randomly assigned (1:1) to receive either usual care alone (usual care group) or usual care plus high-titre convalescent plasma (convalescent plasma group). The primary outcome was 28-day mortality, analysed on an intention-to-treat basis. The trial is registered with ISRCTN, 50189673, and ClinicalTrials.gov, NCT04381936.
Findings:
Between May 28, 2020, and Jan 15, 2021, 11558 (71%) of 16287 patients enrolled in RECOVERY were eligible to receive convalescent plasma and were assigned to either the convalescent plasma group or the usual care group. There was no significant difference in 28-day mortality between the two groups: 1399 (24%) of 5795 patients in the convalescent plasma group and 1408 (24%) of 5763 patients in the usual care group died within 28 days (rate ratio 1·00, 95% CI 0·93–1·07; p=0·95). The 28-day mortality rate ratio was similar in all prespecified subgroups of patients, including in those patients without detectable SARS-CoV-2 antibodies at randomisation. Allocation to convalescent plasma had no significant effect on the proportion of patients discharged from hospital within 28 days (3832 [66%] patients in the convalescent plasma group vs 3822 [66%] patients in the usual care group; rate ratio 0·99, 95% CI 0·94–1·03; p=0·57). Among those not on invasive mechanical ventilation at randomisation, there was no significant difference in the proportion of patients meeting the composite endpoint of progression to invasive mechanical ventilation or death (1568 [29%] of 5493 patients in the convalescent plasma group vs 1568 [29%] of 5448 patients in the usual care group; rate ratio 0·99, 95% CI 0·93–1·05; p=0·79).
Interpretation:
In patients hospitalised with COVID-19, high-titre convalescent plasma did not improve survival or other prespecified clinical outcomes.

Tourism, water and waste in Westland : implications of increasing demand on infrastructure
The growth of tourism, and its consequent benefits, are dependent on the maintenance, if not enhancement, of the West Coast's unique natural environment. Parts of this natural environment have been described as ecologically fragile. There are a range of tourist activities that consume water and produce solid waste and wastewater. An important issue is the tourists' additional demand for potable water and their production of additional wastewater. The major objectives of this research were to: develop models to estimate and project aggregated tourist water use and wastewater
production at Hokitika, Harihari, Franz Josef, and Haast; and assess the adequacy and resourcing of the facilities to provide water, manage wastewater and solid wastes associated with tourism
Tourism, water and waste in Akaroa : implications of tourist demand on infrastructure
There are three components to this research project. The first is the quantitative analysis of the impact of tourist flows to Akaroa on the town's water supply services and wastewater management services. The second is the quantitative analysis of the impact of tourist flows to Akaroa on the town's solid waste management services. The third component is the investigation of the way in which water supply, wastewater and solid waste systems are funded. This analysis investigates whether there are alternative funding systems that are more
efficient, moderate demands, and are more equitable than present funding systems. It also considers how best to allocate any additional costs of water supply if there is growth in tourist numbers
