Visions, Values, and Videos: Revisiting Envisionings in Service of UbiComp Design for the Home
UbiComp has been envisioned to bring about a future dominated by calm
computing technologies making our everyday lives ever more convenient. Yet the
same vision has also attracted criticism for encouraging a solitary and passive
lifestyle. The aim of this paper is to explore and elaborate these tensions
further by examining the human values surrounding future domestic UbiComp
solutions. Drawing on envisioning and contravisioning, we probe members of the
public (N=28) through the presentation and focus group discussion of two
contrasting animated video scenarios, where one is inspired by "calm" and the
other by "engaging" visions of future UbiComp technology. By analysing the
reasoning of our participants, we identify and elaborate a number of relevant
values involved in balancing the two perspectives. In conclusion, we articulate
practically applicable takeaways in the form of a set of key design questions
and challenges.Comment: DIS'20, July 6-10, 2020, Eindhoven, Netherland
A liquid crystalline copper phthalocyanine derivative for high performance organic thin film transistors
This journal is © The Royal Society of Chemistry 2012Bottom-gate, bottom-contact organic thin film transistors (OTFTs) were fabricated using solvent soluble copper 1,4,8,11,15,18,22,25-octakis(hexyl)phthalocyanine as the active semiconductor layer.
The compound was deposited as 70 nm thick spin-coated films onto gold sourceâdrain electrodes supported on octadecyltrichlorosilane treated 250 nm thick SiO2 gate insulators. The performance of the OTFTs was optimised by investigating the effects of vacuum annealing of the films at temperatures between 50 0C and 200 0C, a range that included the thermotropic mesophase of the bulk material. These effects were monitored by ultraviolet-visible absorption spectroscopy, atomic force microscopy and XRD measurements. Device performance was shown to be dependent upon the annealing temperature due to structural changes of the film. Devices heat treated at 100 0C under vacuum (â„10-7 mbar) were found to exhibit the highest field-effect mobility, 0.7 cm2 V^-1 s^-1, with an onâoff current modulation ratio of~107, a reduced threshold voltage of 2.0 V and a sub-threshold swing of 1.11 V per decade.UK Technology Strategy Board (Project no: TP/6/EPH/6/S/K2536J) and UK National Measurement System (Project IRD C02 ââPlastic

Introductory programming: a systematic literature review
As computing becomes a mainstream discipline embedded in the school curriculum and acts as an enabler for an increasing range of academic disciplines in higher education, the literature on introductory programming is growing. Although there have been several reviews that focus on specific aspects of introductory programming, there has been no broad overview of the literature exploring recent trends across the breadth of introductory programming.
This paper is the report of an ITiCSE working group that conducted a systematic review in order to gain an overview of the introductory programming literature. Partitioning the literature into papers addressing the student, teaching, the curriculum, and assessment, we explore trends, highlight advances in knowledge over the past 15 years, and indicate possible directions for future research
