Examiner errors on the WRAT-R

A random sample of 55 WRAT-R protocols, completed by nine practitioners for a metropolitan school district in the South, was analyzed for examiner errors. All nine practitioners made errors, which occurred on 95% of the protocols and averaged 3.0 errors per protocol. The most frequent errors included failures to obtain a correct ceiling or basal, and failures to record examinees' responses. Correction of the examiner errors resulted in changes in 11 standard scores, and 3 additional changes in grade equivalent scores. These results indicate that WRAT-R administration and scoring are not as objective as assumed by the test developers, and that examiner errors on this test can adversely affect diagnostic decisions.     

Eliminating common misconceptions about behavioral psychology: One step toward increased academic productivity

The present article emphasizes the compatibility of behavioral psychology and behavioral interventions in the classroom with today's demands for educational excellence and accountability by classroom teachers. Teacher resistance to the implementation of behavioral interventions is discussed with respect to various misconceptions involving perceived practical obstacles. Misconceptions are corrected and practical suggestions for implementing behavioral interventions are provided. The use of behavioral interventions to achieve accountability and improved student performance is emphasized.     

Increasing acceptability of alternative behavioral interventions through education

The extent to which information provided within the context of regular coursework affects acceptability ratings by prospective teachers of four common behavioral interventions (DRI, home-based reinforcement, ignoring, and time-out) was investigated. General learning principles as well as information about the specific interventions were covered in an educational psychology class (experimental group, n = 34), while control subjects (n = 39) did not receive these lectures. Prelecture acceptability ratings showed no differences between experimental subjects and controls, while postlecture ratings indicated significant increases in acceptability of all interventions except DRI for the experimental group. No increases were evidenced for control subjects. Implications for trainers and consultants are discussed.     

Wechsler short forms: A brief status report

Numerous attempts to develop short forms of Wechsler scales of measurement have been proposed in the psychological literature over the last three decades. In this paper, the three major strategies for development of short forms are described, and an overview of the available validity data is presented. Cautions for the clinical use of short forms and related recommendations for future validity research are offered. It is concluded that while Wechsler short forms may be useful as research instruments, their clinical applications are extremely limited at this time.     

Self-concept,school self-image,satisfaction, and involvement in an alternative high school

Alternative education emphasizes students' psychological development and academic achievement. The present paper reports a case study of the psychological correlates of students' adjustment to a small urban free school. It was expected that: (a) students would have high general self-concept, school selfimage, satisfaction, and involvement; (b) self-concept would discriminate between those high and low in school adjustment: and (c) there would be a positive relationship between school self-image, satisfaction, and involvement. Forty male and thirty female students voluntarily answered the New Morning Student Questionnaire (1972) and the Tennessee Self-Concept Scale (Fitts, 1965). Results showed that students were psychologically well adjusted; they had a somewhat higher self-concept than the norm for high school students; self-concept was a good predictor of school self-image and satisfaction; and there was a positive relationship between school self-image, satisfaction, and involvement.     

Does endurance training improve red blood cell aging and hemorheology in moderate-trained healthy individuals?

ObjectiveTo examine the impact of a 6-week endurance training on red blood cell (RBC) aging and deformability of healthy participants to detect possible improved hemorheological and performance-related adaptations.MethodsA total of 31 participants (17 females and 14 males) performed a 6-week moderate training protocol (three 1-h running sessions per week at 70% of maximal heart rate). Blood was sampled before and after the training. RBCs from each participant were fractioned according to density and age into 4 RBC subfractions. Subfractions were examined for changes of RBC properties, including aging distribution, RBC deformability, RBC microparticles, and phosphatidylserine concentrations. RBC and plasma nitrite levels were measured as indicators of nitric oxide metabolism.ResultsAerobic performance, peak oxygen consumption, ventilatory thresholds, velocity at the aerobic–anaerobic threshold, and lactate at exhaustion improved after training. The relative amount of both young RBCs and old RBCs increased, and the amount of the main RBC fraction decreased. Phosphatidylserine externalization and RBC-derived microparticles decreased. Overall deformability expressed as shear stress required to achieve half-maximum deformation to theoretical maximal elongation index at infinite shear stress improved in unfractioned RBCs (p < 0.001). Nitrite decreased in total (p = 0.001), young (p < 0.001), main (p < 0.001), and old (p = 0.020) aged RBCs and in plasma (p = 0.002), but not in very old RBCs.ConclusionThese results indicate that non-endurance-trained healthy participants benefit from a regular moderate running training program because performance-related parameters improve and a younger RBC population with improved RBC properties is induced, which might support oxygen supply in the microcirculation.     

Non-invasive characterisation of binding media on painted glass magic lantern plates using mid-infrared fibre-optic reflectance spectroscopy

Painted glass magic lantern plates from the Museo Nazionale del Cinema, Torino (Italy), were studied using mid-infrared (mid-IR) fibre-optic reflectance spectroscopy (FORS), a non-invasive technique, to test its potential for the identification of the types of binding media used in the paints. Gum, oil and resin media were identified on the plates and the amounts of these media varied from place to place; the discovery of these media correlate well with the literature on magic lantern plate preparation and painting. The spectra collected are reported uncorrected and also with the fingerprint region corrected with the Kramers–Kronig correction, which corrects distorted peaks caused by specular reflections.     

Not exotic,but too familiar…

ABSTRACT

Urbanization over in last three decades in China has produced and accumulated more and more complex problems and challenges in everyday life. People need different spaces and ways to learn about them, not only to understand what kind of problems they face, but also find a way to act together in order to change their passive situation and take part in the process which always seem to be dominated by government and technology. “Womende Chengshi” (Our Cities) citizen forum was built in 2012 and has lasted for almost 5 years in Shanghai. It aims to create a new educational space for citizens to discuss emerging city problems and to imagine alternative ways of urban life. After a concise introduction about this forum in Chinese social context, this paper will focus on three points. First, while the ideal setting suggests that citizens are everyone living in the city, “Our Cities” actually confronts the concrete ones shaped by various spaces and limited times in the whole city system. So how to struggle with different forces in limited time and space in everyday life is the main duty this forum needs to face. The third point follows: what kind of standard we could have to estimate such self-education process?
