Was Humpty Dumpty Right? An Exploratory Study of Semantic Priming and Lexical Access

This study investigates the way subjects gain access to their internal lexicon and assesses the effects of context on this process. The focus is on ambiguous words that are homographic but pronounced differently. A total of 35 adult subjects read aloud from word lists containing the same target homographs. In two conditions the targets were primed by words calculated to influence subjects either towards a regular or irregular pronunciation; a third condition without primers provided a baseline check. The influence of primers on subjects’ pronunciations was recorded and calculated. Results confirmed a significant influence of primers on pronunciation for a majority of target words. Further analysis showed groups of subjects were significantly (p<0.001) influenced by semantic primers. However, results are interpreted cautiously and proposals are made for a more rigorous study using this exploratory work as a basis. Finally, the potential of semantic priming studies for future research is outlined.     

The rise of the machines: Artificial intelligence meets scholarly content

Key points

• New forms of human/machine dialogue are emerging as robots understand vast amounts of content rather than simply indexing content as strings of characters.
• Recognizing strings of characters as entities (e.g. = names = authors) allows for meaningful associations between entities and reasoning over these relationships.
• Web‐scale adoption of the Semantic Web approach has been slow because it is too complex to implement and does not scale.
• User intent, discovered through conversational models of human–computer interaction, allows for a deeper understanding of exactly what researchers are looking for.
• Personal agents hold the promise of finding information that we will find useful before we have started to look for it.
• Publishers can use Academic Knowledge APIs to interpret academic user queries and find rich information from the Microsoft Academic Graph.

     

The Role of Rural Public Libraries in Small Business Development

Like all public libraries, rural public libraries in the Appalachian region can play a significant role in the economic development of their communities. Economic development in rural communities potentially benefit from many of the same resources and services all enjoy at public libraries, including free and public Internet access, space, education, question answering, and materials on many business-related subjects. This article reports survey findings of current activities that rural public libraries perform in one state, namely the state of Tennessee, as a case study to apply the lessons and insights to other parts of the United States. The discussion includes assessment of activities and some recommendations to streamline and stimulate all public libraries in conducting this assistance efficiently.     

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.     

Physiological responses to 1000-m ergometer time-trial performance in outrigger canoeing

Graded exercise tests are commonly used to assess peak physiological capacities of athletes. However, unlike time trials, these tests do not provide performance information. The aim of this study was to examine the peak physiological responses of female outrigger canoeists to a 1000-m ergometer time trial and compare the time-trial performance to two graded exercise tests performed at increments of 7.5 W each minute and 15 W each two minutes respectively. 17 trained female outrigger canoeists completed the time trial on an outrigger canoe ergometer with heart rate (HR), stroke rate, power output, and oxygen consumption (VO2) determined every 15 s. The mean (+/- s) time-trial time was 359 +/- 33 s, with a mean power output of 65 +/- 16 W and mean stroke rate of 56 +/- 4 strokes min(-1). Mean values for peak VO2, peak heart rate, and mean heart rate were 3.17 +/- 0.67 litres min(-1), 177 +/- 11 beats min(-1), and 164 +/- 12 beats min(-1) respectively. Compared with the graded exercise tests, the time-trial elicited similar values for peak heart rate, peak power output, peak blood lactate concentration, and peak VO2. As a time trial is sport-specific and can simultaneously quantify sprint performance and peak physiological responses in outrigger canoeing, it is suggested that a time trial be used by coaches for crew selection as it doubles as a reliable performance measure and a protocol for monitoring peak aerobic capacity of female outrigger canoeists.     

Differentiated Curriculum Design: Responding to the Individual and Group Needs of Students with Learning Difficulties with Self‐regulated Learning Strategies

The purpose of this study was to explore special educational curriculum design at senior secondary school level and whether this helps to enhance the academic attainment and self‐confidence of students with learning difficulties. An in‐depth discussion focuses on lesson planning for the individual needs and group needs of students by implementation of self‐regulated learning strategies, based on a case study in a special school in Hong Kong. A multiple methods research design was envisaged for the implementation phase of this participatory action research. Lesson observations, video recordings, teachers’ diaries and students’ interviews were collected during one academic year in a form 5 (equal to year 12 in the UK) classroom. It is suggested that curriculum design should include various elements: learning knowledge, values and attitudes, and generic skills. This differentiated curriculum design showed how subject learning targets could be responsive to both the individual and the group needs of students with learning difficulties. Conclusions also indicate that assisting students to become aware of their individual needs is beneficial both for learning and for curriculum design.
