In the last decade, voluntary efforts by firms to reduce their environmental impacts have received increasing attention from both policymakers and scholars. This article discusses polluters' incentives to reduce their releases. In particular, using data from Canada's National Pollutant Release Inventory, it examines the impacts of conventional…

This is the first report on the findings of a survey carried out on 578 students entering computing courses at seven institutes of technology in Ireland in 2001. The progress of this cohort of students is charted through the four years of their course using questionnaires and interviews. It is envisioned that the study will highlight the different…

This paper represents Part I of a two-part study examining preservice teachers' development of a personalized, research-based Science Teaching Rationale (STR). Researchers have historically documented the application of the "rationale paper" (Clough, 1992; Veronesi, 1998) using qualitative methodologies. Since the rationale paper continues to…

Enzyme kinetics is a difficult subject for students to learn and for tutors to teach. During the practicals included in the biochemical courses at the Faculty of Chemistry of Universidad Nacional Autonoma de Mexico, we found that the students acquire good training in the calculations to obtain kinetic parameters such as K[subscript m], V[subscript…

The "dual-channel" hypothesis (Lawton, 1996), which suggests the dual-antecedent pattern for positive and negative aspects of psychological well-being, was tested by examining the differential relationships between objective and subjective measures of family support (family contact, family quality, perceived importance of family) and…

This paper describes a school/university graduate induction program that has provided support to beginning teachers since 1994. A 10-year follow-up study of program graduates was recently conducted to examine these questions: (a) How many graduates are still in the education profession? (b) How many have remained in the classroom? and (c) What are…

Purpose: This study examined lexical-semantic organization of bilingual children in their 2 languages and in relation to monolingual age-mates. Method: Twelve Mandarin-English bilingual and 12 English monolingual children generated 3 associations to each of 36 words. Responses were coded as paradigmatic ("dog-cat") or syntagmatic ("dog-bark").…

Ultrasound can be used to address unresolved questions in phonological theory. To date, some studies have shown that results from ultrasound imaging can shed light on how differences in phonological elements are implemented. Phenomena that have been investigated include transitional schwa, vowel coalescence, and transparent vowels. A study of…

This multimethod study generated and tested a "best evidence" model of school improvement processes (SIP) capable of improving student achievement. Initially developed through the review of a comprehensive body of previous empirical research, the model was further refined through a 2, 5-year longitudinal study in 10 schools. A quantitative test of…

This article presents an experimental study demonstrating how 120 learners use help tools in a virtual learning set-up. More specifically, several types of tutoring are investigated to find out the extent of the use of help tools in each. The effects of two independent variables which may have an impact on the behaviour of learners are studied:…

The purpose of this study was to measure and compare the extent to which three groups of stakeholders in the welfare-to-work process judge a selected list of workplace topics as important for inclusion in the curriculum. Topics were derived from the 1991 report of the Secretary's Commission on Achieving Necessary Skills (SCANS). A 45-item survey…

For individuals who have complex communication needs and for the interventionists who work with them, the collection of empirically derived data that support the use of an intervention approach is critical. The purposes of this study were to continue building an empirically derived base of support for, and to compare the relative effectiveness of…

This study investigated effects of an audiotape self evaluation intervention on the instructional behavior of three student teacher interns in classrooms for students with various developmental disabilities. A multiple baseline design was used to evaluate the intervention. Results indicated a positive effect on all interns' use of specific social…

The study was designed to investigate the relative efficacy of the guided inquiry and the expository teaching methods on the achievement in and attitude to biology of students of different levels of scientific literacy. Four research questions and four null hypotheses were posed and formulated respectively, to guide the work. It was hypothesized…

The blueprint which the Federal Government rolled out for guiding educational technology practice which was based on the report of the Joint Consultative Committee on Educational Technology in 1991 is a relatively new innovation in educational institutions in Nigeria. However, the adoption of new innovation depends on the perception of teachers…
