Exploring Physicality in the Design Process

The design process used in the development of many products we use daily and the nature of the products themselves are becoming increasingly digital. Although our whole world is turning ever more digital, our bodies and minds are naturally conceived to interact with the physical. Very often, in the design of user-targeted information appliances, the physical and digital processes are formulated separately and usually, due to cost factors, they are only brought together for user testing at the end of the development process. This not only makes major design changes more difficult but it can also significantly affect the users’ level of acceptance of the product and their experience of use. It is therefore imperative that designers explore the relationship between the physical and the digital form early on in the development process, when one can rapidly work through different sets of ideas. The key to gaining crucial design information from products lies in the construction of meaningful prototypes. This paper specifically examines how physical materials are used during the early design stage and seeks to explore whether the inherent physical properties of these artefacts and the way that designers interpret and manipulate them have a significant impact on the design process. We present the findings of a case study based on information gathered during a design exercise. Detailed analysis of the recordings reveals far more subtle patterns of behaviour than expected. These include the ways in which groups move between abstract and concrete discussions, the way groups comply with or resist the materials they are given, and the complex interactions between the physicality of materials and the group dynamics. This understanding is contributing to ongoing research in the context of our wider agenda of explicating the fundamental role of physicality in the design of hybrid physical and digital artefacts.

The Ha Luminosity Function and Star Formation Rate at z\sim 0.2

We have measured the Ha+[N II] fluxes of the I-selected Canada-France Redshift Survey (CFRS) galaxies lying at a redshift z below 0.3, and hence derived the Ha luminosity function. The magnitude limits of the CFRS mean that only the galaxies with M(B) > -21 mag were observed at these redshifts. We obtained a total Ha luminosity density of at least 10^{39.44\pm 0.04} erg/s/Mpc^{3} at a mean z=0.2 for galaxies with rest-fame EW(Ha+[N II]) > 10 Angs. This is twice the value found in the local universe by Gallego et al. 1995. Our Ha star formation rate, derived from Madau (1997) is higher than the UV observations at same z, implying a UV dust extinction of about 1 mag. We found a strong correlation between the Ha luminosity and the absolute magnitude in the B-band: M(B(AB)) = 46.7 - 1.6 log L(Ha). This work will serve as a basis of future studies of Ha luminosity distributions measured from optically-selected spectroscopic surveys of the distant universe, and it will provide a better understanding of the physical processes responsible for the observed galaxy evolution.Comment: Accepted for publication in ApJ, 14 pages, LaTeX (macro aas2pp4.sty), 6 figure

The THISL SDR system at TREC-8

This paper describes the participation of the THISL group at the TREC-8 Spoken Document Retrieval (SDR) track. The THISL SDR system consists of the realtime version of the ABBOT large vocabulary speech recognition system and the THISLIR text retrieval system. The TREC-8 evaluation assessed SDR performance on a corpus of 500 hours of broadcast news material collected over a five month period. The main test condition involved retrieval of stories defined by manual segmentation of the corpus in which non-news material, such as commercials, were excluded. An optional test condition required required retrieval of the same stories from the unsegmented audio stream. The THISL SDR system participated at both test conditions. The results show that a system such as THISL can produce respectable information retrieval performance on a realistically-sized corpus of unsegmented audio material

The impact of prenatal parental locus of control on children's psychological outcomes in infancy and early childhood:a prospective 5 year study

Locus of control is one of the most widely studied concepts in the history of personality psychology. In spite of its popularity and its associations with numerous relevant outcomes, the ability of locus of control to predict future behaviors involving parenting effectiveness has been under researched. The few parent locus of control children's outcome studies are characterized by cross-sectional methodologies that focus on mothers. The present study uses a prospective methodology to compare data on mothers' and fathers' locus of control with their child's behavior outcomes from a large scale research project, the Avon Longitudinal Study of Parents and Children (ALSPAC). Based on Rotter's Social Learning Theory published in 1954 and past empirical research, it was predicted and found that parent internality was associated with more positive child outcomes than parent externality. More specifically, when both parents were internal, their children had more positive outcomes in sleeping, eating, and tantrum behavior as compared to any other parent locus of control combination. However external parents had a less restrictive attitude which appeared to have a more beneficial effect on picky eating. Results confirmed how important parent locus of control is in the lives of children. Based on the findings, researchers are urged to develop interventions to change advice to parents and promote more internal locus of control among parents

Evaluating a natural horsemanship program in relation to the ISES first principles of horse training

The ISES training principles provide an excellent starting point for professionals and horse owners. Currently, there does not seem to be an accepted protocol for evaluating horse training programs against the ISES principles. We suggest an approach to this, using Parelli Natural Horsemanship as our subject for evaluation. This initial pilot study (single-subject / n=1), trials two analytical methods, as applied to the current, video-based teaching materials from Parelli (latest DVD set, published and commercially available from 2015, supplied by Parelli for use in this study). The two methods used were: (i) ethology-based video observation / logging and (ii) discourse analysis of the language used to teach. The ethology-based approach uses an ethogram, which lists the behavioural characteristics of a human trainer adhering to the ISES principles. Computer-based ‘continuous sampling’ of Parelli video clips was used to log the frequencies of ISES principles. Inter Observer Reliability of the analysis to date was assessed using a two-way, mixed, absolute agreement, average-measures ICC (Intra Class Correlation). This evaluated observer agreement in the frequency count ratings for the ISES principles. Discourse analysis is a qualitative research methodology, applied across many domains including politics and health. Discourse analysis allows us to study transcripts of horse training materials, codifying the words, phrases and linguistic structures. Understanding the context within which training language is used, and its meaning to both the speaker and audience, makes it possible to evaluate compatibility with the ISES principles. Results for the ethology-based observations found all ISES principles present (1-10). High frequency counts for principles 2 & 10. Low counts for principles 5 & 7. Inter Observer Reliability (2 observers) was in the ‘excellent’ range (ICC=0.79). The high ICC value suggests that a minimal amount of measurement error was introduced by the independent observers, and therefore statistical power is not substantially reduced. At this stage (without an ICC value closer to 1.0 or further calibrating observers), increasing the evidence against random effects would require more extensive trials (p=0.16). The interim results from the discourse analysis shows consistent congruence between the Parelli materials and the ISES principles, particularly in the areas of: training according to the horse’s ethology and cognition, using learning theory appropriately, forming consistent habits, avoiding flight responses and ensuring that the horse should always be as calm as possible (1, 2, 7, 9 and 10)

Audio information access from meeting rooms.

We investigate approaches to accessing information from the streams of audio data that result from multi-channel recordings of meetings. The methods investigated use word-level transcriptions, and information derived from models of speaker activity and speaker turn patterns. Our experiments include spoken document retrieval for meetings, automatic structuring of meetings based on self-similarity matrices of speaker turn patterns and a simple model of speaker activity. Meeting recordings are rich in both lexical and non-lexical information; our results illustrate some novel kinds of analysis made possible by a transcribed corpus of natural meetings

The link between the nature of the human–companion animal relationship and well-being outcomes in companion animal owners

Research into the impact of companion animals on well-being has been both extensive and inconclusive, with studies finding both positive and negative relationships. The present research explored three previously unexamined relationship science concepts that may help clarify whether companion animals provide well-being benefits: self-expansion (the process of adding positive content to the self through incorporating new resources and perspectives into one’s identity or engaging in novel, exciting activities), perceived pet responsiveness, and perceived pet insensitivity; as well as attachment. We focused on dog and cat owners’ depression, anxiety, positive and negative affect, and loneliness through an online survey with a large sample population (N = 1359). We found that perceived pet insensitivity is a significant positive predictor of depression, anxiety, negative affect, and loneliness; that attachment is a significant positive predictor of depression, anxiety, and loneliness, and a significant negative predictor of positive affect; and that self-expansion is a significant positive predictor of positive affect, and a significant negative predictor of loneliness. Loneliness emerged as a mediator in the relationship between perceived pet insensitivity, attachment, self-expansion, and all mental well-being outcome variables. These findings indicate that perceived pet insensitivity, attachment, and self-expansion may play an important yet neglected role in well-being outcomes
