Spelling errors as a window on variations in phonological deficits among students with dyslexia

Characteristics of spelling development and spelling error patterns were examined in 100 schoolchildren (aged 7 to 15 years) previously identified as dyslexic with specific phonological weaknesses. Within a severely restricted range, spelling development generally followed a normal course despite wide individual variation. The group was divided using two different spelling criteria: (1) global spelling stage, and (2) a split based on the number of spelling confusions involving phonetically similar consonants. Comparisons using either criterion led to the conclusion that better spellers are also better readers and are more skilled in phoneme manipulation. Regression analyses suggested that measures of phonemic segmenting and manipulation make independent contributions to the acquisition of word reading. Phoneme segmenting explained significant variance only when students were subdivided according to errors in coding confusable consonants. Implications for instruction are considered.     

Factors associated with physical activity referral uptake and participation

The aim of this study was to examine participant and scheme characteristics in relation to access, uptake, and participation in a physical activity referral scheme (PARS) using a prospective population-based longitudinal design. Participants (n = 3762) were recruited over a 3-year period. Logistic regression analyses identified the factors associated with the outcomes of referral uptake, participation, and completion (> or = 80% attendance). Participant's age, sex, referral reason, referring health professional, and type of leisure provider were the independent variables. Based on binary logistic regression analysis (n = 2631), only primary referral reason was associated with the PARS coordinator making contact with the participants. In addition to the influence of referral reason, females were also more likely (odds ratio 1.250, 95% confidence interval 1.003-1.559, P = 0.047) to agree to be assigned to a leisure provider. Referral reason and referring health professional were associated with taking up a referral opportunity. Older participants (1.016, 1.010-1.023, P < 0.001) and males were more likely to complete the referral. In conclusion, the PARS format may be less appropriate for those more constrained by time (women, young adults) and those with certain referral reasons (overweight/obesity, mental health conditions). More appropriate targeting at the point of referral could improve participation rates by revealing or addressing barriers that might later result in dropout.     

Comparison of the PPVT and PPVT-R for preschool children: Implications for the practitioner

The aim of this study was to compare the standard scores and age scores obtained from the Peabody Picture Vocabulary Test (1965) and the Revised Peabody Picture Vocabulary Test (1981). The sample included 88 preschool children who ranged in age from 2–6 to 5–11. The mean PPVT IQ score was 98.9 (SD = 16.9) and Mental Age was 55.2 months (SD = 20.1 mo.); the mean PPVT-R Standard Score Equivalent was 95.4 (SD = 13.4) and Age Equivalent was 48.5 months (SD = 14.6 mo.). The mean PPVT IQ and Mental Age scores were significantly higher (p < .01) than the respective Standard Scores and Age Equivalents. Implications for the use of the Revised PPVT are discussed.     

Our moral condition in cyberspace

Some kinds of technological change not only trigger new ethical problems, but also give rise to questions about those very approaches to addressing ethical problems that have been relied upon in the past. Writing in the aftermath of World War II, Hans Jonas called for a new ``ethics of responsibility,'' based on the reasoning that modern technology dramatically divorces our moral condition from the assumptions under which standard ethical theories were first conceived. Can a similar claim be made about the technologies of cyberspace? Do online information technologies so alter our moral condition that standard ethical theories become ineffective in helping us address the moral problems they create? I approach this question from two angles. First, I look at the impact of online information technologies on our powers of causal efficacy. I then go on to consider their impact on self-identity. We have good reasons, I suggest, to be skeptical of any claim that there is a need for a new, cyberspace ethics to address the moral dilemmas arising from these technologies. I conclude by giving a brief sketch of why this suggestion does not imply there is nothing philosophically interesting about the ethical challenges associated with cyberspace.
