EFTPOs: electronic funds transfer at point of sale

The concept of EFTPOS is introduced and its development from cash dispensers and credit cards through smart cards to the concept of a single, universal multifunction card is outlined. Such a card could subsume the array of cards that many individuals now possess, as well as contain advanced features. The article includes an examination of the main technologies used with a strong emphasis on the security measures employed, since fraud is a major concern     

The science and practice of empirically supported treatments.

The impact on Canadian professional psychological treatment practices of the American Psychological Association""s Division 12 (Clinical Psychology) Task Force""s development of criteria and listings for empirically supported psychological treatments, along with other industrial efforts to standardize the identification of treatments with established efficacy is described in the article by J. Hunsley et al (see record 1999-01869-001). Here Hunsley et al extend their previous discussion and reply to other commentaries (see records 1999-01869-002, 1999-01869-003, 1999-01869-004, 1999-01869-005, 1999-01869-006) by viewing the current emphases in the Canadian health care system on accountability and empirically supported treatment (ESTs) as an unparalleled opportunity for professional psychology to deliver on its birthright. The generalizability of US experiences to Canadian contexts is discussed. Clinical practice guidelines should and will become the norm for providing evidence-based services in psychology, yet it would be impossible to develop such a guideline without empirical evidence proving that there are "best" interventions for a given problem. Canadian research issues in this light are discussed along with future challenges to professional psychology in Canada. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The pigments of cottonseed

Summary A method for the purification of gossypol has been developed which yields material differing in optical properties from those previously reported for gossypol preparations. A colorimetric test for extractable gossypol has been described. It has been shown that cottonseed contains at least three pigments in addition to gossypol. Some of the properties of the three pigments have been reported. One of these newly detected pigments, gossypurpurin, has been shown to be the substance which, mixed with gossypol, constitutes the so-called “red gossypol” of Podol’skaja. The frequently reported water-dispersable blue pigment of cottonseed has been shown to be either a complex of gossypol, gossypurpurin and protein or a mixture of two protein-pigment complexes. Its dissociation into the two pigments and protein has been accomplished. Presented before the 34th Annual Meeting of the American Oil Chemists’ Society, New Orleans, Louisiana, May 12–14, 1943.     

FISCHERPLOTS: An Excel spreadsheet for computing Fischer plots of accommodation change in cyclic carbonate successions in both the time and depth domains

Fischer plots are plots of accommodation (derived by calculating cumulative departure from mean cycle thickness) versus cycle number or stratigraphic distance (proxies for time), for cyclic carbonate platforms. Although many workers have derived programs to do this, there are currently no published, easily accessible programs that utilize Excel. In this paper, we present an Excel-based spreadsheet program for Fischer plots, illustrate how the data are input, and how the resulting plots may be interpreted. The plots can be used to derive periods of increased accommodation, shown on the plots as a rising limb (which commonly matches times of more open marine, subtidal parasequence development). Times of decreased accommodation, shown on the plots as a falling limb, generally are coincident with thin, shallow, peritidal parasequences.     

Ontology-driven hypothesis generation to explain anomalous patient responses to treatment

Within the medical domain there are clear expectations as to how a patient should respond to treatments administered. When these responses are not observed it can be challenging for clinicians to understand the anomalous responses. The work reported here describes a tool which can detect anomalous patient responses to treatment and further suggest hypotheses to explain the anomaly. In order to develop this tool, we have undertaken a study to determine how Intensive Care Unit (ICU) clinicians identify anomalous patient responses; we then asked further clinicians to provide potential explanations for such anomalies. The high level reasoning deployed by the clinicians has been captured and generalised to form the procedural component of the ontology-driven tool. An evaluation has shown that the tool successfully reproduced the clinician’s hypotheses in the majority of cases. Finally, the paper concludes by describing planned extensions to this work.     

The Structured Assessment of Violence Risk in Youth as a predictor of recidivism in a United Kingdom cohort of adolescent offenders with conduct disorder.

This prospective study examined the predictive validity of the Structured Assessment of Violence Risk in Youth (SAVRY) and the Psychopathy Checklist: Youth Version (PCL: YV) in 99 male adolescents who were assessed in custody and followed up 12 months post release. Outcome data on recidivism were based on official Home Office records. The base rates for violent and general recidivism, respectively, were 38.4% and 70.7%. The predictive validity of the SAVRY Risk Total and the SAVRY Risk Rating was moderate for both violent and general recidivism, but both showed incremental validity in predicting outcomes compared with the PCL: YV. Data are discussed in relation to the limited published international literature. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Traits as goal-based categories: The importance of goals in the coherence of dispositional categories.

It is argued that goals are central to the meaning and structure of many traits and help define the prototypicality structure of those traits. Partly on the basis of L. W. Barsalou's (1985) work on goal-derived categories, it was predicted that goals help define the judged prototypicality of many trait-related behaviors and the confidence with which people make trait inferences from those behaviors. Consistent with this hypothesis, ratings of the extent to which behaviors achieved the goal associated with a trait strongly predicted the typicality of the behaviors. Furthermore, the rated goal-relatedness of a behavior also strongly predicted the confidence with which people would make a trait inference from that behavior. It is suggested that goals play a major role in the conceptual coherence of traits and other social categories. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Thermoelastic Stress Analysis of a GRP Tee Joint

A detailed study of the stresses that are developed in a glass reinforced plastic (GRP) tee joint under service loads is described. The joints are fabricated by laminating a boundary angle over a radiused fillet on either side of the ‘tee’. Full-field stress characterisation data is provided by a thermoelastic analysis of the tee joint. Calibration procedures that allow the thermoelastic data to be compared with the results of a finite element analysis are detailed. The results of the thermoelastic analysis are compared with values obtained from the finite element analysis. The applicability of thermoelastic analysis as a validation tool for finite element models of composite materials is assessed.     

DETERMINATION OF IRON OXIDE AND TITANIA IN CLAY REFRACTORIES1

Customary method of determining iron oxide and titania from ignited R₂O₂ precipitate requires considerable time. Direct titration of fusions with sodium carbonate is impossible because of gelatinous silica. Direct titration of fusions with potassium bisulphate is accurate with clays low in silica and unfired clays. By treating with hydrofluoric and sulphuric acid, and dissolving with dilute hydrochloric and precipitating the R₂O₂ by ammonium hydroxide and then fusing with potassium bisulphate the iron and titanium oxide can with accuracy be titrated. A detail method of procedure is given.
