Demo of three ways to use a computer to assist in lab
The objective is to help the slow learner and students with a language problem, or to challenge the advanced student. Technology has advanced to the point where images generated on a computer can easily be recorded on a VCR and used as a video tutorial. This transfer can be as simple as pointing a video camera at the screen and recording the image. For more clarity and professional results, a board may be inserted into a computer which will convert the signals directly to the TV standard. Using a computer program that generates movies one can animate various principles which would normally be impossible to show or would require time-lapse photography. For example, you might show the change in shape of grains as a piece of metal is cold worked and then show the recrystallization and grain growth as heat is applied. More imaginative titles and graphics are also possible using this technique. Remedial help may also be offered via computer to those who find a specific concept difficult. A printout of specific data, details of the theory or equipment set-up can be offered. Programs are now available that will help as well as test the student in specific areas so that a Keller type approach can be used with each student to insure each knows the subject before going on to the next topic. A computer can serve as an information source and contain the microstructures, physical data and availability of each material tested in the lab. With this source present unknowns can be evaluated and various tests simulated to create a simple or complex case study lab assignment
Domestic Abuse in the UK Sri Lankan Tamil Community: Understanding Shame
Introduction: Shame resulting from domestic abuse can have wide-reaching negative consequences for victim-survivors. Shame has been theorised as a transcultural, transdiagnostic, embodied emotion, the experience of which differs according to the norms and expectations of groups. More therefore needs to be understood on behalf of mental health services about the group-specific experiences of shame, to be able to provide targeted support for victim-survivors. No studies have previously examined the shame-experiences of Sri Lankan Tamil victim-survivors. Tamil culture holds honour and shame as key values, and understand health through a holistic, social determinants model, which fits with a shame-focussed approach to therapeutic care. Understanding shame may therefore be important to developing culturally-appropriate therapeutic care for Tamil victim-survivors.
Methods: Semi-structured interviews were conducted with first-generation Sri Lankan Tamil victim-survivors of domestic abuse. Data were analysed using reflexive Thematic Analysis.
Results: Shame was shaped by criticism, victim-blaming, betrayal, and control. Shame experiences included fear and pain of external judgement, mothering guilt, degradation of sexual abuse, and feeling vulnerable and exposed. It also included protecting others from shame.
Conclusion: Shame can be a powerful experience for Sri Lankan Tamil victim-survivors of domestic abuse, with negative implications for wellbeing, relationships and escaping abuse. Tamil victim-survivors may therefore benefit from therapeutic support that reduces shame and increases dignity
A space servicing telerobotics technology demonstration
Supervised telerobotic controls provide the key to successful remote servicing, as demonstrated in the telerobot testbed of the jet propulsion laboratory. Such advanced techniques and systems are specially applicable to ground-remote operations for servicing tasks, which are to be performed remotely in space and to be operated under human supervision from the ground. Laboratory demonstrations have successfully proven the utility of such techniques and systems. Instrumental to the success of supervised robotic operations are the techniques called object designate and relative target. In addition, a technique called universal camera calibration was also applied in the telerobot testbed. Generalized compliant control techniques were used in the robotic removal and insertion operations. These techniques were proven successful in task situations where preprogrammed automation cannot be adequately exercised due to errors, changes, or omission in the worksite data base
A near-real-time full-parallax holographic display for remote operations
A near real-time, full parallax holographic display system was developed that has the potential to provide a 3-D display for remote handling operations in hazardous environments. The major components of the system consist of a stack of three spatial light modulators which serves as the object source of the hologram; a near real-time holographic recording material (such as thermoplastic and photopolymer); and an optical system for relaying SLM images to the holographic recording material and to the observer for viewing
Mitochondria and neuroprotection in stroke: Cationic arginine-rich peptides (CARPs) as a novel class of mitochondria-targeted neuroprotective therapeutics
Stroke is the second leading cause of death globally and represents a major cause of devastating long-term disability. Despite sustained efforts to develop clinically effective neuroprotective therapies, presently there is no clinically available neuroprotective agent for stroke. As a central mediator of neurodamaging events in stroke, mitochondria are recognised as a critical neuroprotective target, and as such, provide a focus for developing mitochondrial-targeted therapeutics. In recent years, cationic arginine-rich peptides (CARPs) have been identified as a novel class of neuroprotective agent with several demonstrated mechanisms of action, including their ability to target mitochondria and exert positive effects on the organelle. This review provides an overview on neuronal mitochondrial dysfunction in ischaemic stroke pathophysiology and highlights the potential beneficial effects of CARPs on mitochondria in the ischaemic brain following stroke
Improving driver behaviour by design : a cognitive work analysis methodology
Within the European Community both the environmental and safety costs of road
transport are unacceptably high. ‘Foot-LITE’ is a UK project which aims to encourage
drivers to adopt ‘greener’ and safer driving practices, with real-time and retrospective
feedback being given both in-vehicle and off-line. This paper describes the early
concept development of Foot-LITE, for which a Cognitive Work Analysis (CWA) was
conducted. In this paper, we present the results of the first phase of CWA – the Work
Domain Analysis, as well as some concept interface designs based on the WDA to
illustrate its application. In summary, the CWA establishes a common framework for
the project, and will ultimately contribute to the design of the in-vehicle interface
