Do dyslexics misread a ROWS for a ROSE?

Insufficient knowledge of the subtle relations between words’ spellings and their phonology is widely held to be the primary limitation in developmental dyslexia. In the present study the influence of phonology on a semantic-based reading task was compared for groups of readers with and without dyslexia. As many studies have shown, skilled readers make phonology-based false-positive errors to homophones and pseudohomophones in the semantic categorization task. The basic finding was extended to children, teens, and adults with dyslexia from familial and clinically-referred samples. Dyslexics showed the same overall pattern of phonology errors and the results were consistent across dyslexia samples, across age groups, and across experimental conditions using word and nonword homophone foils. The dyslexic groups differed from chronological-age matched controls by having elevated false-positive homophone error rates overall, and weaker effects of baseword frequency. Children with dyslexia also made more false-positive errors to spelling control foils. These findings suggest that individuals with dyslexia make use of phonology when making semantic decisions both to word homophone and non-word pseudohomophone foils and that dyslexics lack adequate knowledge of actual word spellings, compared to chronological-age and reading-level matched control participants.     

Expanding teacher work roles: a resource for retention or a recipe for overwork?

This paper illuminates the tensions between the rhetoric and presumed rewards of an expanded conception of teachers' work and the work demands and strains introduced by such a conception. Based on data collected in the United States, this paper draws on multi‐day, 24‐hour time and task diaries recorded by case‐study teachers, together with ethnographic interviews and observations, to illuminate the disjuncture between reform rhetoric and workplace demands. I use these data to assess the usefulness of existing theories of overwork as they may apply to teachers and teaching. This paper suggests that teacher overwork is, in part, a result of the expansion of teacher work roles. The argument unfolds in three parts. First, teachers' work roles have been expanded but structural supports for the expansion have been uneven. Second, the nature and extent of organizational support influences teacher experience of role expansion and, finally, teachers who embrace the expanded role conception strive to sustain it even in the absence of organizational supports. This results in overwork: here overwork is taken to mean working beyond the contractual day, week and year. Teachers' contracts specify their working day; when they work beyond this time without pay, then they are overworking. Current explanations of overwork do not adequately account for the case of teachers' overwork.     

long与for a long time

表示时间的副词long与表示时间长度的词组for a long time意思相近,但用法却不一样。下面谈谈二者之间的区别: 一、long作为时间副词,常出现在否定句和疑问句中。for a long time常出现在肯定句中。例如: (1)-Have you been working here long?你在这儿工作很久了吗? -No,not long,but my brother’s been in the firm for a very long time.不,我在这里工作时间不长,而我弟弟在这家公司工作的时间 很长了。     

Long and for a Long Time

long和for a long time均可以用来表示时间，意为“长期”“长时间”等。但两者在用法上，有不少需要注意之处： 1．long作为表达时间的副词，通常用于否定句或疑问句，一般不用于肯定句。肯定句中要用（for）a long time。例如：

Navigation system for a smart wheelchair

Recent results on the development of a navigation system for a smart wheelchair are presented in this paper. In order to reduce the development cost, a modular solution is designed by using commercial and low cost devices. The functionalities of the tracking control system are described. Experimental results of the proposed assistive system are also presented and discussed.     

Proposal for a cross layer scheme for real-time wireless video

INTRODUCTION Increase in wireless system capacity through 3G services and innovative low bit rate video coding techniques have made it possible to have mobile multimedia services on hand-held systems. High quality real-time multimedia services are slowly be- ing deployed on hand-held systems. However large scale deployment at low cost is still to be realized due to technological challenges such as stringent power control under severely fading environments and the susceptibility of high qu…     

Is There a Need for a European Institutional Research?

Recent changes in European higher education have accompanied a strong desire and need by national ministries to have comparable data across institutions and a growing recognition from campus leaders that effective planning and decision-making requires reliable institutional data and analyses. This has induced changes and restructuring of duties and roles of administration, administrative staff and academic staff. In North America, internal institutional data analysis is often referred to as institutional research. We examine the roles and functions of institutional research within North America and how the changes within European higher education have created a purpose for institutional research. Specifically, we explore the topical areas of institutional assessment, data management, institutional governance, as well asthe changing identity of academic professionals within European universities. Within our examination, we explore in-depth one European country’s higher education system to demonstrate how history, culture and legislative changes manifest into a need for institutional research.     

Implementation of a new PC based controller for a PUMA robot

This paper describes the replacement of a controller for a programmable universal machine for assembly (PUMA) 512 robot with a newly designed PC based (open architecture) controller employing a real-time direct control of six joints. The original structure of the PUMA robot is retained. The hardware of the new controller includes such in-house designed parts as pulse width modulation (PWM) amplifiers, digital and analog controllers, I/O cards, signal conditioner cards, and 16-bit A/D and D/A boards. An Intel Pentium IV industrial computer is used as the central controller. The control software is implemented using VC programming language. The trajectory tracking performance of all six joints is tested at varying velocities. Experimental results show that it is feasible to implement the suggested open architecture platform for PUMA 500 series robots through the software routines running on a PC. By assembling controller from off-the-shell hardware and software components, the benefits of reduced and improved robustness have been realized.     

Suggestions for Conducting a Reading Comprehension Lesson

I. Aims and Content of a Reading Comprehension Lesson As stated in the New English Course curriculum, "the aim of senior school English teaching is to develop students' overall abilities of listening, speaking, reading and writing, with more emphasis on reading". The main task of a reading comprehension lesson is to develop students' reading ability and help them form good habit of reading. Enabling students
