Lying idiots: reality television & lie to me

This article addresses perhaps the key question for Television Studies: Who does television think you are? It argues that Reality Television answers this question by producing its viewers as, in the Classical Greek sense, idiots (meaning private and ignorant persons). Idiots are the perfect target for the advertising dollar that supports commercial television production. As Reg Grundy observes, Reality Television is anything but reality. With its tight framings of reality, it paradoxically operates to sever the viewing self from reality—from the “truth” of life. Lie to Me is the type of television we are left with after the demise of Reality Television. Lie to Me makes us self-conscious, in the strongest sense, and thus sustains the mission of Reality Television. By dragging the notion of reality into its self-serving fictions, it puts the viewer into the dangerous position of being unable to lie to television. If Reality Television constrained reality to falsity, Lie to Me implicates the viewer in the zone where falsity transforms into reality. Lastly, this article enquires into the possibilities, in today’s television ecology, for a mode of TV citizenship that would counter the abject viewing position of the consumerist idiot.

Having the courage to measure up for education

In this “age of measurement” it is increasing difficult for educators to educate (Biesta, 2010). The pressures to conform to the demands of bureaucratic authorities generally trump over educators and their aims to educate. One of the factors contributing to this is because as Dewey (1929a, p. 133) has argued, our aims and our desires to educate don’t have deep enough roots. He suggests that educators ought to have “cultivated” and “significant conscious desires” and a disposition to be “courageous” (1929a, p. 134; 1929b, p. 38) in order to attain the independence to ensure that our practices in education are indeed educational. Dewey (1934) called such a disposition a “religious attitude” because it engages with the ultimate concerns that people can aspire towards. In this paper I shall argue that this religious attitude of Dewey’s which can enable our roots to deepen, does not just pertain to our aims of education as an intellectual phenomenon. Rather it can be understood as existential (Webster, 2009) in the sense that aims of education are specific to individuals in situation – not to abstract or universal understandings of education. It shall also be argued that this existential aspect of our being is emotive, and deepening its roots might enable us to become more courageous and thus more able to challenge the barriers inherent in our current ‘age of measurement’ so that education may become more of a reality.

Effectiveness and feasibility of virtual reality and gaming system use at home by older adults for enabling physical activity to improve health-related domains: a systematic review

Background
use of virtual reality and commercial gaming systems (VR/gaming) at home by older adults is receiving attention as a means of enabling physical activity.

Objective
to summarise evidence for the effectiveness and feasibility of VR/gaming system utilisation by older adults at home for enabling physical activity to improve impairments, activity limitations or participation.

Methods
a systematic review searching 12 electronic databases from 1 January 2000–10 July 2012 using key search terms. Two independent reviewers screened yield articles using pre-determined selection criteria, extracted data using customised forms and applied the Cochrane Collaboration Risk of Bias Tool and the Downs and Black Checklist to rate study quality.

Results
fourteen studies investigating the effects of VR/gaming system use by healthy older adults and people with neurological conditions on activity limitations, body functions and physical impairments and cognitive and emotional well-being met the selection criteria. Study quality ratings were low and, therefore, evidence was not strong enough to conclude that interventions were effective. Feasibility was inconsistently reported in studies. Where feasibility was discussed, strong retention (≥70%) and adherence (≥64%) was reported. Initial assistance to use the technologies, and the need for monitoring exertion, aggravation of musculoskeletal symptoms and falls risk were reported.

Conclusions
existing evidence to support the feasibility and effectiveness VR/gaming systems use by older adults at home to enable physical activity to address impairments, activity limitations and participation is weak with a high risk of bias. The findings of this review may inform future, more rigorous research.

Condensing a priori data for recognition based augmented reality

My research proposes novel methods to reduce the cardinality of a priori data used in recognition based augmented reality, whilst retaining distinctive and persistent features in the sets. This research will help reduce latency and increase accuracy in recognition based pose estimation systems, thus improving the user experience for augmented reality applications.

A Novel Mo and Nb Microalloyed Medium Mn TRIP Steel with Maximal Ultimate Strength and Moderate Ductility

The multi-phase, metastable, and multi-scale (M3) constitution of a novel transformation-induced plasticity (TRIP) steel (Fe-0.17C-6.5Mn-1.1Al-0.22Mo-0.05Nb, wt pct) was designed through thermodynamic calculations combined with experimental analysis. In this study, Mo and Nb microalloying was used to control the fraction of retained austenite and its mechanical stability during tensile deformation and to improve the yield strength. Thermodynamic calculations were developed to determine the critical annealing temperature, at which a large fraction of retained austenite (~38 pct) would be obtained through the effects of solute enrichment. The experimental observation was in good agreement with the predicted results. According to the critical annealing temperature, such an ultrafine (<200 nm) M3, microstructure with optimum mechanical stability was successfully achieved. The results of this work demonstrated the superior performance with improved yield strength of 1020 to 1140 MPa and excellent ductility (>30 pct), as compared with other TRIP steels. Both angle-selective backscatter and electron backscatter diffraction techniques were employed to interpret the transformation from the deformed martensitic laths to the ultrafine austenite and ferrite duplex structure.
