Abstract
Bioinformatics projects are currently under way at numerous universities and in industry. These projects typically involve processing large amounts of biological data and comparison of biological signals or sequences. Much of the existing work in bioinformatics software is based on such languages and platforms as Perl and Unix. This paper, proposes software architectures in Java to support biological applications allowing access of biological data using server‐side Java programs on the Internet. The architecture follows the standards of unified modeling language (UML). UML architecture diagrams are presented for the Java‐based bioinformatics applications. In addition, an overview of the Bio‐Soft project under way at The Biomedical Research Institute (BRI) of the University of Wisconsin‐Parkside is provided, which includes research and instructional software for bioinformatics applications.

Abstract
Purpose
The purpose of this paper is to review and discuss the literature focusing on defining and measuring sentiments so as to understand their role in stock market behavior.
Design/methodology/approach
Critical review of the literature by analyzing myriad scholarly articles. The study is based on an analysis of 81 scholarly articles to critically analyze the approach toward defining and measuring market sentiments. The articles have been examined to identify and critique different classification of sentiment measures. A discussion is built to scrutinize the sentiment measures under the purview of theoretical underpinnings of the investor sentiment theory as well.
Findings
With more than five decades of research, the sentiment construct in finance literature is still ill-defined. Myriad empirical proxies of sentiment measures have led to conflicting results. The sentiment construct defined in financial theories needs to be revisited from the lens of sentiments defined in psychology.
Research limitations/implications
The study is limited to analyzing the role of individual and institutional sentiments in equity markets. There is a need to explore sentiments with respect to different investment styles and strategies along with the type of investors.
Practical implications
Developing a suitable sentiment proxy can result in devising profitable trading strategies for investors. Understanding factors driving investor sentiments will help regulators to become more proactive and frame better policies.
Originality/value
This paper has leveraged psychology literature to highlight the limitations in development of sentiment construct in finance literature. By identifying stylized facts from reviewing the empirical literature, it highlights areas for future research.

Abstract
The purpose of this article is to present an overview of the history and development of transaction log analysis (TLA) in library and information science research. Organizing a literature review of the first twenty‐five years of TLA poses some challenges and requires some decisions. The primary organizing principle could be a strict chronology of the published research, the research questions addressed, the automated information retrieval (IR) systems that generated the data, the results gained, or even the researchers themselves. The group of active transaction log analyzers remains fairly small in number, and researchers who use transaction logs tend to use this method more than once, so tracing the development and refinement of individuals' uses of the methodology could provide insight into the progress of the method as a whole. For example, if we examine how researchers like W. David Penniman, John Tolle, Christine Borgman, Ray Larson, and Micheline Hancock‐Beaulieu have modified their own understandings and applications of the method over time, we may get an accurate sense of the development of all applications.

Abstract
This year's survey focuses on reference works published in 1980. The two exceptions, reviewed in Part Two, were deemed too important to omit (Women's History Sources; A Guide to Archives and Manuscript Collections in the United States, and Index to the Papers of the Continental Congress, 1774–1789, which supplements the Index to the Journals of the Continental Congress). Among the 1980 imprints are a fairly even mix of bibliographies, indexes, biographical compilations and encyclopedic dictionaries. The Harvard Encyclopedia of American Ethnic Groups is an especially outstanding work published in 1980.

Abstract
The emergence and maturation of the social sciences is an important component of the expansion of institutions of higher learning in the 20th century. The discipline of Political Economy, increasingly institutionalized in various Canadian universities in the early decades of the century, secured a Chair at the University of Manitoba in 1909. After 1914, its title became “Political Economy and Political Science” and the department subsequently served “as the great mother department to which were attached newer social science disciplines until it was deemed appropriate to let them launch out on their own” (Pentland, 1977, p. 3). Political Science became independent in 1948, Geography in 1951, and Sociology and Anthropology in 1962 (p. 4). Agricultural Economics, which was taught in the Manitoba Agricultural College, became its own department when the college joined the university in 1924. In the 1930s, Agricultural Economics was absorbed into Department of Political Economy. However, according to Pentland (pp. 4–5) it was not until the late 1940s that agricultural economics became a significant “sub-department.” It subsequently separated itself from Political Economy and, in 1954, became an independent department in the Faculty of Agriculture (p. 5). The result of these disciplinary developments was that the faculty of the Department of Political Economy had, from time to time, members whose expertise lay outside the increasingly well-defined terrain of economics. Despite this, however, they did not seem to have any long-lasting direct impact on shaping and defining the curricula in Economics. Since these other disciplines left and became independent when they had reached a certain size or degree of influence, Economics was left to define and pursue its own agenda unencumbered by the needs of these former associates.

Abstract
Judging from the titles in this year's survey, 1982/83 was the “Year of the Bibliography.” Wherein half of last year's reviews were bibliographies, almost three‐fourths of this year's are (11 out of 15): much of this can be attributed to the computer. The outstanding (and anachronistic) exception to this general truth is Beers' Bibliography, which was compiled laboriously by hand.

Abstract
Purpose
The purpose of this paper is to assess trading strategies adopted by each large trader group and examine their effects on the volatility in the interest rate futures markets.
Design/methodology/approach
The Grinblatt et al.'s (1995) measure of momentum strategy is used to estimate the degree momentum and contrarian strategies. Then, regression analysis is used to determine the effects of trading strategies on volatility.
Findings
Up until 2005, the trades by non-clearing member firms in the futures market were separated from institutional traders providing us the opportunity to study trading strategies adopted by large distinct trading groups and its effects on volatility in the futures markets. It is found that individual traders use momentum strategy, whereas market makers and institutional traders use contrarian strategy. Momentum strategy adopted by individual traders increases volatility whereas contrarian strategy dampens volatility. Moreover, it is found that institutional traders engage more actively in contrarian trading when individual traders cause excessive volatility. The two distinct trading groups were separately tracked prior to 2005 giving us a unique window to determine the effect of the traders that conduct momentum trading as opposed to the ones that are contrarian traders. After the reclassification, the institutional trading group exhibited weaker contrarian strategy which can be attributed to the inclusion of non-clearing firm traders.
Originality/value
This study documents the first empirical evidence that shows off-exchange futures trader group is not composed of only pure noise makers, but there are short-term forecasters in its group. The authors also show a unique finding that noises caused by off-exchange group is from momentum strategy that they use, whereas contrarian strategy is used by institutional trader lower volatility.
