An Investigation into Collaboration and Knowledge Management during Product Development in the Aerospace and Defence Industry
Organisations need to overcome a number of challenges, including improving knowledge management, to ensure competitiveness in today’s global business environment. Product development and engineering design decisions are typically based on the knowledge available within enterprises. An ability to quickly discover and capture this knowledge and communicate with colleagues is required to enable effective outputs. An in-depth industry investigation, conducted within a leading manufacturing organisation in the Aerospace and Defence Industry (ADI), confirmed that knowledge management is only average. Employees would welcome the introduction of new technology to improve knowledge sharing and feel competent to use Web 2.0 and social media technologies. Based on the investigation, an interactive groupware prototype employing collaborative Web 2.0 technologies has been proposed. The prototype will be introduced as a case study to engineers within the collaborating company during product development projects with benefits in productivity and collaborative practices being assessed
Increasing Light Absorption and Collection Using Engineered Structures
In recent years we have witnessed an explosion of interest in two dimensional (2D) materials, due to their unique physical properties. Excitement surrounds the promise of replacing conventional bulk photodetectors with devices based on 2D materials, allowing better integration, flexibility and potentially improving performance. However, the low inherent light absorption of 2D materials is an outstanding issue to be solved. In this chapter we review two independent approaches to tackling this problem, which have the potential to be combined to find a robust solution. The first approach involves patterning the substrate with a rod-type photonic crystal (PhC) cavity structure, which is shown to increase the light absorption into a 2D material flake coupled spatially to the cavity mode. Secondly, we review 2D–compatible solid immersion lenses (SILs) and their ability to increase both the optical magnification of the structures they encapsulate, and the longevity of the material. SILs have been shown to reduce the requirements for complex optics in the implementation of 2D materials in optoelectronic devices, and also in preserving the photodetector’s optical performance over long periods of time. Finally, we show how by combining rod-type PhC cavities with SILs, we can improve the performance of 2D material-based photodetectors
The visual word form system in context
According to the “modular” hypothesis, reading is a serial feedforward process, with part of left ventral occipitotemporal cortex the earliest component tuned to familiar orthographic stimuli. Beyond this region, the model predicts no response to arrays of false font in reading-related neural pathways. An alternative “connectionist” hypothesis proposes that reading depends on interactions between feedforward projections from visual cortex and feedback projections from phonological and semantic systems, with no visual component exclusive to orthographic stimuli. This is compatible with automatic processing of false font throughout visual and heteromodal sensory pathways that support reading, in which responses to words may be greater than, but not exclusive of, responses to false font. This functional imaging study investigated these alternative hypotheses by using narrative texts and equivalent arrays of false font and varying the hemifield of presentation using rapid serial visual presentation. The “null” baseline comprised a decision on visually presented numbers. Preferential activity for narratives relative to false font, insensitive to hemifield of presentation, was distributed along the ventral left temporal lobe and along the extent of both superior temporal sulci. Throughout this system, activity during the false font conditions was significantly greater than during the number task, with activity specific to the number task confined to the intraparietal sulci. Therefore, both words and false font are extensively processed along the same temporal neocortical pathways, separate from the more dorsal pathways that process numbers. These results are incompatible with a serial, feedforward model of reading
Experience Disclosing Mental Health Conditions Among College Students from Different Ethnic Backgrounds
Aim: The current study compared disclosure of mental health problems to staff, faculty, and peers among college students from different ethnic backgrounds. Background: Although there are differences in mental health stigma between college students from different ethnic backgrounds, there is limited research on whether these differences are associated with negative experiences disclosing mental health conditions on campus. Methods: The sample (N = 66) was 71% female; average age was 19.03 years (SD = 1.14). Participants identified as Latino/a (35.4%), Asian American (33.8%), Caucasian (13.8%), or other/mixed ethnicity (16.9%). Results: For disclosure to staff, there was a main effect of ethnicity. Post-hoc analyses found that Latino/a students were significantly more comfortable disclosing mental health problems to staff than Asian American students. There were no significant effects for disclosure to faculty or peers. Conclusions: This preliminary study suggests that universities must optimize outreach and mental health services for different ethnic groups to improve campus experience around mental health conditions
International Evidence on the Impact of Health-Justice Partnerships: A Systematic Scoping Review
BACKGROUND: Health-justice partnerships (HJPs) are collaborations between healthcare and legal services which support patients with social welfare issues such as welfare benefits, debt, housing, education and employment. HJPs exist across the world in a variety of forms and with diverse objectives. This review synthesizes the international evidence on the impacts of HJPs. METHODS: A systematic scoping review of international literature was undertaken. A wide-ranging search was conducted across academic databases and grey literature sources, covering OECD countries from January 1995 to December 2018. Data from included publications were extracted and research quality was assessed. A narrative synthesis approach was used to analyze and present the results. RESULTS: Reported objectives of HJPs related to: prevention of health and legal problems; access to legal assistance; health improvement; resolution of legal problems; improvement of patient care; support for healthcare services; addressing inequalities; and catalyzing systemic change. There is strong evidence that HJPs: improve access to legal assistance for people at risk of social and health disadvantage; positively influence material and social circumstances through resolution of legal problems; and improve mental wellbeing. A wide range of other positive impacts were identified for individuals, services and communities; the strength of evidence for each is summarized and discussed. CONCLUSION: HJPs are effective in tackling social welfare issues that affect the health of disadvantaged groups in society and can therefore form a key part of public health strategies to address inequalities
Mechanisms of Stem Borer Resistance in Sorghum
A number of sorghum genotypes resistant to the spotted stem borer (Chilo partellus Swinhoe) have been identified using natural and artificial infestations at ICRISAT. Resistance is attributed to ovipositional nonpreference and antibiosis mechanisms. The major plant characters identified include early panicle initiation and rapid internode elongation. In resistant genotypes, these factors were reflected in the success of first instar larval establishment in the leaf whorl, interval between hatching and larvae boring in the stem, larval mass, and survival rate. Success of the first instar larvae to establish in the whorl is also influenced by physical and chemical plant characteristics. A chemical factor in the surface wax of some sorghum genotypes is associated with larval disorientation

Review of Injection Therapy Clinics Performed by Physiotherapists Working in Primary Care.
Objectives
To determine painscores for injection therapy and to review the overall change in outcomes post injection for a variety of musculoskeletal injections compared with the previous audits of a NHS Primary care Physiotherapy injection clinic.
Methods
Subjects were assessed using a numerical rating scale between 0 to 10 before and 4 weeks post injection.
Results
All average painscale scores were reduced 4 weeks after injection for all conditions. There is an overall average reduction in pain on provoking activity of 45.7%. Trigger finger/thumb (65.0%) demonstrated the most significant reduction in pain.
Contrary to a common patient perception, injection therapy is not an exceptionally painful experience, with an average score of 3.2.
Discussion
Results are comparable with previous scores for injections carried out within the same NHS Primary care Physiotherapy clinic
