Abstract

Applications often require a fast, single-threaded search algorithm over sorted data, typical in table-lookup operations. We explore various search algorithms for a large number of search candidates over a relatively small array of logarithmically-distributed sorted data. These include an innovative hash-based search that takes advantage of floating point representation to bin data by the exponent. Algorithms that can be optimized to take advantage of SIMD vector instructions are of particular interest. We then conduct a case study applying our results and analyzing algorithmic performance with the EOSPAC package. EOSPAC is a table look-up library for manipulation and interpolation of SESAME equation-of-state data. Our investigation results in a couple of algorithms with better performance with a best case 8x speedup over the original EOSPAC Hunt-and-Locate implementation. Our techniques are generalizable to other instances of search algorithms seeking to get a performance boost from vectorization.

9. Balancing Judicial Independence and Accountability in a Transitional State: The Case of Thailand

Author

Pimentel, David

Subjects
Thailand, judicial independence
Abstract

Balancing judicial independence against judicial accountability is a classic problem, but the debate has often taken place without reference to specific legal cultures and traditions, and there is compelling reason to believe that the “right” balance may be different in different societies. Thailand is in transition, so the models of established Western democracies may be ill-suited to the problems and issues of the Thai judiciary. Moreover, independence and accountability are not ends in themselves, but means to the same end: that of fair, impartial, and effective justice. Independence can help, primarily by bolstering the “judicial courage” exercised by judges called upon to rule in difficult cases. Accountability can help as well, primarily by bolstering the “integrity” judges demonstrate in their performance on the bench. In light of this, the structural solutions for the judiciary under a new Thai constitution should be crafted in light of (1) the history, tradition, and culture of the Thai judiciary, (2) the degree of courage and integrity already manifested among Thai judges, and (3) those structures and mechanisms that can leverage the Thai judges’ strengths and ameliorate, or at least mitigate, their weaknesses. Until Thailand has a new constitution, the courts there will be seriously handicapped in playing their critical roles of providing fair and impartial adjudication and of protecting human and other legal rights. When, indeed if, constitutional checks and balances are put in place, the stage will be set for a calming of the turmoil in Thailand. But that can only happen if the judiciary is sufficiently empowered and independent to play that constitutional role, while showing both sufficient integrity to avoid corruption and sufficient restraint not to overreach into the political realm. In other words, the individual judges must exhibit both this courage and this integrity in their rulings. And the structure of the judiciary—the mechanisms for protecting the judges (to promote independence), and for policing them (to promote accountability)—will be important in facilitating that result, restoring public confidence in the legal and political system, and ultimately strengthening the rule of law in the Kingdom of Thailand.

17. Evaluation of Selected Websites at the U.S. Department of Education: Increasing Access to Web-Based Resources.

Author

Syracuse Univ., NY. School of Information Studies., Hert, Carol A., Eschenfelder, Kristin R., McClure, Charles R., Rubin, Jeffrey, Taffet, Mary D., Abend, Jennifer E., and Pimentel, David M.

Abstract

The Department of Education's Web site (http://www.ed.gov) is a rich information and service resource that is widely used both within the Department of Education and by a variety of users external to the Department. It provides extensive information about the Department and its programs and services, enables users to interact efficiently with some programs, and serves diverse audiences. As the Web site has grown and developed, a number of issues have arisen that require attention. This document presents results of an evaluation of the site from four perspectives: management assessment, policy analysis, log and transaction analysis, and usability testing. The full report is presented in five major sections and capped by an Executive Summary. Following Section I: "Introduction" in which the study objectives and methods are outlined, each of the four assessment techniques and associated findings are represented as individual sections--Section II: "Management Assessment"; Section III: "Policy Assessment"; Section IV: "Technical Assessment"; and Section V: "User Assessment." Within each section, the methodology is detailed, findings presented, and recommendations suggested. Appendices include details of data collection instruments and other background information.

33. Comment: Protecting Childhood Independence and the Families Who Embrace It.

Author

Pimentel, David

Subjects
*AUTONOMY (Psychology), *CHILD welfare, *PARENTING, *CHILD protection services
Abstract

The author comments on author Fenja Schick-Malone's note entitled "Letting the Kids Run Wild: Free-Range Parenting and the (De)Regulation of Child Protective Services," which focuses on the problems with legal efforts to push back against hyper-protective parenting or intensive parenting. Topics discussed include initiatives by scholars and activists to change attitudes toward the importance of childhood independence in the U.S., and the impact of these legal efforts on children and families.
