How Do Profoundly Deaf Children Learn to Read?

Reading requires two related, but separable, capabilities: (1) familiarity with a language, and (2) understanding the mapping between that language and the printed word (Chamberlain & Mayberry, 2000; Hoover & Gough, 1990). Children who are profoundly deaf are disadvantaged on both counts. Not surprisingly, then, reading is difficult for profoundly deaf children. But some deaf children do manage to read fluently. How? Are they simply the smartest of the crop, or do they have some strategy, or circumstance, that facilitates linking the written code with language? A priori one might guess that knowing American Sign Language (ASL) would interfere with learning to read English simply because ASL does not map in any systematic way onto English. However, recent research has suggested that individuals with good signing skills are not worse, and may even be better, readers than individuals with poor signing skills (Chamberlain & Mayberry, 2000). Thus, knowing a language (even if it is not the language captured in print) appears to facilitate learning to read. Nonetheless, skill in signing does not guarantee skill in reading—reading must be taught. The next frontier for reading research in deaf education is to understand how deaf readers map their knowledge of sign language onto print, and how instruction can best be used to turn signers into readers.     

Comparison of methods for determining power generated on a rope-braked cycle ergometer during low-intensity exercise

This study compares the instrumentation and analysis techniques used when determining the power expended pedalling a rope-braked ergometer manufactured by Monark (Sweden) during a low intensity test. Power values were generated by eight subjects. The instrumentation consisted of load cells to measure the rope brake forces, a tachometer to measure the flywheel velocity and instrumented pedal cranks manufactured by Schoberer Rad Messtechnik (SRM). The subjects pedalled a rope-braked ergometer at 60 rev min^-1, against a resistance of 3 kg, for 5 minutes. Three different measurements of the mean power were recorded and these were compared with the value given by Monark. The SRM cranks provided two sets of results using different software packages supplied with the cranks. SRM standard software is used for taking measurements during training and cycle races over long time periods. An additional piece of software is provided by SRM called Ptnew, which gives readings of torque and pedal cadence over periods up to 30 seconds. Using the values supplied by Monark each subject generated 180 W of power. The mean power for the eight subjects, measured using the SRM cranks, was 170.36 W (SD 4.11) using the alternative SRM software (Ptnew) over a 30 second period and 173.68 W (SD 2.21) using the standard SRM software. From the direct measurement of the brake forces and flywheel velocity the mean power across the eight subjects was 148.90 W (SD 5.89). The SRM cranks measure the input power, whereas the direct measurement system measures the power output excluding mechanical losses. These values give a figure for the mechanical efficiency for the roped-braked ergometer of 88%. It was found that Monark overestimates the power generated by the subjects when compared with both the SRM systems and the direct measurement instrumentation.     

Job ads,jobs, and researchers: Searching for valid sources

Research on librarians' roles and responsibilities often takes the form of content analysis of job advertisements found in aggregators such as print journals and websites. Whether these ads help us better understand librarianship depends on how representative the source data is for each study—the line going from jobs, to job ads, then to job ad sources. Print sources dominate even in studies published after 2000. This study examines where reasonably representative job advertisements for academic libraries may be found by starting at the origin: the institutions themselves. It finds that commonly used print sources provide only a small fraction of available positions (the majority of which are those in doctoral institutions), and even the most comprehensive aggregator misses nearly half of the available positions. Taking job ad samples directly from institutions is time-consuming but provides more representative data. Smaller colleges pose a particular challenge for finding ads as few of them have openings at any one time and few of their ads appear in national aggregators.

Out of the ordinary: recapturing the liberal traditions of a university education through field courses

This article aims to stimulate debate about the nature of field courses in higher education. We use a colloquium format that allows each of us to reflect on the philosophy of field course teaching and our writing endeavours to establish a dialogue between the authors and leave the reader with a sense of curiosity. It starts with a position paper that sets out a particular viewpoint on field courses to which responses were invited. Two of the respondents were experienced field-course teachers in disciplines traditionally associated with this type of curriculum, the other a lecturer in a non-field-course-oriented discipline.
