Faculty members' provision of instructional accommodations to students with LD

The existing research on the instructional accommodation process of college students with learning disabilities focuses on attitudes and theoretical models without delineating actual practices. To date, the discussion of facilitating factors and barriers to this process has been broad and lacking specificity. Surveys were mailed to 485 faculty members at the University of Massachusetts, Amherst, who received an instructional accommodation form from the office of Learning Disabilities Support Services in the fall of 1995. The survey focused on faculty members' reported degree of ease or difficulty in implementing instructional accommodations, their perceptions regarding adequacy of support, and their own beliefs and understandings concerning the need for and benefit of providing instructional accommodations. The results indicate that beliefs about the helpfulness of and need for instructional accommodations were associated with the provision of the accommodations. Also, a perception of support from the University influenced the ease of providing instructional accommodations. A significant difference was found between the behavior of tenure-track faculty and non-tenure-track faculty.     

Attitudes toward the level of men's involvement in abortion decisions

College students completed a questionnaire that assessed their attitudes toward the level of male responsibility in abortion decisions. Overall, both men and women thought that men should have some degree of involvement in the abortion decision. However, as expected by the first hypothesis, men indicated a desire for more responsibility in the abortion decision than women thought the men should have. A second hypothesis predicted women would feel more strongly than men that abortion was strictly a woman's issue. Contrary to the hypothesis, women tended to disagree that abortion was strictly a women's issue. Implications of the findings are discussed.     

The Relative Efficiency of Departments at a Turkish Engineering College: A Data Envelopment Analysis

In this study, Data Envelopment Analysis is used to measure relative efficiencies of academic departments of an engineering college. Input and output criteria are determined and measured utilizing the academic personnel performance measurement scheme of the College. New measures are developed to compare departments of different disciplines. The discriminating power of the measurement models is improved by restricting criteria weights directly and by using a multiple criteria decision making approach. Sensitivity of the results to exclusion of a criterion and changes in relative importance of the criteria is analyzed. Evaluation of the results jointly by the college administration and the departments is explained for a successful efficiency improvement mechanism.     

Wavelets: Applications to image compression-II

We explain here, the wavelet based thresholding procedure, one of the key factors behind the successful application of wavelets in image compression. We then elaborate on quantization and go on to outline the basic ideas underlying Huffman coding, the other important tool for data compression.     

Roundtable: what is temperament? Four approaches

4 current approaches to understanding temperament are discussed in the roundtable. In an introductory overview, Goldsmith outlines some of the major convergences and divergences in the understanding of this concept. Theorists representing 4 positions--Goldsmith, Buss and Plomin, Rothbart, and Thomas and Chess--outline their views by responding to each of 6 questions: How do you define temperament and explain the boundaries of the concept? What are the elements of temperatment? How does the construct of temperament permit you to approach issues or organize data in ways that are possible only if this construct is invoked? How does temperament develop? To what extent do you consider temperament to be a personological versus a relational or an interactional construct? and How does your approach deal with issues of temperamental "difficulty"? In 2 commentaries on the theorists' answers, Hinde highlights differences among their positions and indicates issues that current theories of temperament must take into consideration, and McCall draws on common aspects to propose a synthesizing definition that draws on all 4 approaches.
