Adjustable drill bar replaces complex jigs

Adjustable drill bar incorporates a micrometer screw which, when used in conjunction with standard gage blocks, provides rapid method of drill hole location and reduces time and skill requirements for precision drilling on large surfaces. Device picks up oddly dimensioned tool hole points and acts as sine drill bar

Strengthening OA practice: using intervention logic to support drives for change

The aim of the JISC Open Access (OA) Pathfinder programme is to “develop shareable models of good practice with regard to implementation of research funders’ OA requirements”. With the sector-wide shift to OA and with growing funders’ OA mandates, the Pathfinder scheme reflects a real need to enhance compliance with the agenda. Fundamental to this project is understanding how people approach OA, and how processes can be designed to address this. This brief paper summarises an approach to building stronger institutional approaches to Open Access using intervention logic. The process, drawn from a behaviour change intervention framework supports research management and library staff to explore the key areas of change needed and consider how best to address these. The intervention mapping tool which was first trialled at a workshop on Uncovering researcher behaviours at Oxford Brookes on 20 May 2015 is supplied at the end of this document to support this process

Predictive eye movements are driven by goals, not by the mirror neuron system

The importance of a mirror neuron system (MNS) as a mecha-nism for understanding the actions of others has been estab-lished (e.g., Rizzolatti, Fadiga, Gallese, & Fogassi, 1996). Neurons in the primate premotor cortex fire both when a monkey performs an action (e.g., grasping) and when the monkey ob-serves someone else performing the same action. It has also been proposed that theMNS is the starting point for understanding the intentions and goal-directed behavior of others (Fogassi et al., 2005; Gallese & Goldman, 1998). Consistent with this view, Falck-Ytter, Gredebäck, and von Hofsten (2006) argued that the MNS is implicated in proactive goal-directed (predictive) eye movements. In a series of eye-tracking studies, participants observed a toy object moving along a trajectory toward a con-tainer. Adults and 1-year-old infants looked ahead of the toy and toward the goal container only when a hand was observe

The onus on us? Stage one in developing an i-Trust model for our users.

This article describes a Joint Information Systems Committee (JISC)-funded project, conducted by a cross-disciplinary team, examining trust in information resources in the web environment employing a literature review and online Delphi study with follow-up community consultation. The project aimed to try to explain how users assess or assert trust in their use of resources in the web environment; to examine how perceptions of trust influence the behavior of information users; and to consider whether ways of asserting trust in information resources could assist the development of information literacy. A trust model was developed from the analysis of the literature and discussed in the consultation. Elements comprising the i-Trust model include external factors, internal factors and user's cognitive state. This article gives a brief overview of the JISC funded project which has now produced the i-Trust model (Pickard et. al. 2010) and focuses on issues of particular relevance for information providers and practitioners

Both symbolic and embodied representations contribute to spatial language processing: Evidence from younger and older adults

Building on earlier neuropsychological work, we adopted a novel individual differences approach to examine the relationship between spatial language and a wide range of both verbal and nonverbal abilities. Three new measures were developed for the assessment of spatial language processing: spatial naming, spatial verbal memory, and verbal comprehension in spatial perspective taking. Results from a sample of young adults revealed significant correlations between performance on the spatial language tasks and performance on both the analogous (non-spatial) verbal measures as well as on the (non-verbal) visual-spatial measures. Visual-spatial abilities, however, were more predictive of spatial language processing than verbal abilities. Furthermore, results from a sample of older adults revealed impairments in visual-spatial tasks and on spatial verbal memory. The results support dual process accounts of meaning, and provide further evidence of the close connection between the language of space and non-linguistic visual-spatial cognition

Concrete manufacture with un-graded recycled aggregates

Purpose – The purpose of this paper is to investigate whether concrete that includes un-graded recycled aggregates can be manufactured to a comparable strength to concrete manufactured from virgin aggregates. Design/methodology/approach – A paired comparison test was used to evaluate the difference between concrete made with virgin aggregates (plain control) and concrete including recycled waste. Un-graded construction demolition waste and un-graded ground glass were used as aggregate replacements. With regard to concrete, compressive strength is widely used as a measure of suitability as being fit for purpose. Therefore compressive strength was mainly used to compare the different concrete batches; however density was measured across the range of samples. Findings – The findings show that a lower average compressive strength is achieved when compared to the plain control sample manufactured with virgin aggregates. Correct particle packing may not be achieved and grading of aggregates is essential prior to mix design. The recycled aggregate was highly variable in terms of the fine particle content, which affected the water demand of the concrete. Practical implications – This manufacturing practice is considered necessary because of the current trend in using waste products in concrete to replace binders and aggregates; thus reducing the impact on the environment and use of finite natural resources. The research shows the risk of mixing concrete using a simple aggregate replacement without careful aggregate grading and adjustments to the mix design. Originality/value – The paper examines 100 per cent ungraded aggregate replacement with glass and demolition waste

The hidden mechanics of Solomon Islands budget processes – understanding context to inform reforms

"This paper examines the development funds managed by Solomon Islands Government (SIG) from 2004 to 2008 (called the consolidated development budget). This may appear dry, but correctly interpreted, provides a wealth of information about how the SIG operates. First, because budgets aim to efficiently allocate resources to meet objectives, an analysis can present a better indication of the SIG’s priorities than formal pronouncements, policies, or plans. Second, because the budget is the culmination of a process, examining the process illustrates how SIG operates ..." - page 1AusAI

Double jeopardy : a socio-demographic profile of homeless jobseekers aged 18-35

This article reports on socio-demographic research that was undertaken as part of a broader project to improve service delivery to homeless jobseekers aged 18-35 years (Grace et 01 2005). The broader project, known as Yp4, is a randomised controlled trial of joined up services and programs for young homeless jobseekers. Yp4 is an initiative of four organisations: Hanover Welfare Services, Brotherhood of St Laurence, Melbourne Citymission and Loddon Mallee Housing Services This paper does not provide detailed information about the Yp4 trial, rather it reports on socio-demographic research undertaken to set the context in which Yp4 operates. For further details regarding Yp4 please see Horn (2004). When we set out to prepare a socio-demographic profile of homeless jobseekers aged 18-35 years, we found two main ways to count homelessness and at least two ways to quantify unemployment. Obtaining data and assessing its quality was far from easy, and this research was an exercise in frustration and perseverance. In this article we discuss the complexities of counting homelessness and unemployment, and the educated guesswork involved in estimating numbers of homeless jobseekers. We present a tentative socio-demographic profile; and we make suggestions regarding better access to data in the future

Users' trust in information resources in the Web environment: a status report

This study has three aims; to provide an overview of the ways in which trust is either assessed or asserted in relation to the use and provision of resources in the Web environment for research and learning; to assess what solutions might be worth further investigation and whether establishing ways to assert trust in academic information resources could assist the development of information literacy; to help increase understanding of how perceptions of trust influence the behaviour of information users
