(1996), Biosorption of copper from aqueous solutions by plant root tissues. Journal of Fermentation and Bioengineering, 81 (5), 458-463. Full Text: J\J Fer Bio81, 458.pdf Abstract: Root tissues of two common weeds, Amaranthus spinosus and Solanum nigrum, were found to adsorb dissolved Cu2+ in aqueous solutions. The adsorption can be represented by Langmuir and Freundlich isotherms. The equilibrium adsorption level was determined to be a function of initial solution pH and temperature. The adsorption capacity decreased with decreasing pH and increasing temperature. Alkaline pretreatment of the root tissue doubled the adsorption capacity. Ground powders of the root tissues were immobilized within alginate gel beads (3 mm diameter) for use in a packed-bed column. The mass transfer coefficient was calculated using the rate of metal ion adsorption to the gel beads. Surface film mass transfer resistance was important. Continuous adsorption/desorption cycles for removing and concentrating Cu2+ in solution were performed using the packed-bed column, which would be useful for treating wastewater containing trace amounts of copper ions.

(1996), Removal of cadmium from aqueous solution by the filamentous cyanobacterium Tolypothrix tenuis. Journal of Fermentation and Bioengineering, 82 (6), 580-584. Full Text: J\J Fer Bio82, 580.pdf Abstract: Cadmium removal was investigated using the filamentous cyanobacterium, Tolypothrix tenuis, which exhibited a high level of Cd tolerance and had the highest Cd removal ability among 17 cyanobacterial strains obtained in Thailand. The removal of Cd was equilibrated within 30 min, and the type of Cd removal could be described by the Langmuir isotherm. Cadmium removal by T. tenuis is thus suggested to be caused by adsorption of Cd onto the cell surface, T. tenuis showed consistent Cd adsorption ability over a wide range of temperature and pH. Tile adsorption of Cd was not strongly affected in the presence of Na, K, Ca, and Mg ions. These results suggest that T. tenuis may be applicable to the removal of Cd from surface and ground water in certain outdoor situations.

(1998), Removal of mercury ion by the moss Pohlia flexuosa. Journal of Fermentation and Bioengineering, 86 (2), 197-201. Full Text: J\J Fer Bio86, 197.pdf Abstract: The moss Pohlia flexuosa was obtained as the protonema from its matured capsules. It was grown by shaking in modified Murashige-Skoog’s medium, and the dry weight obtained was 40 mg per 20 ml medium after 15 d. The ature protonema removed Hg2+ from aqueo solutions. The higher the initial Hg2+ concentration, the higher the amount of Hg2+ removed, and the concentration factor, which is an indicator of the ability to remove heavy metals, was 2000 l/g of dry moss at 50 g /ml of HgCl2. The optimal pH and temperature for Hg2+ removal were 7.0 and 25C, respectively. Sodium azide and dinitrophenol at 0.1 mM inhibited Hg2+ removal up to a relative removal of 81 and 77%, respectively. The importance of two processes, bioaccumulation and adsorption, in the removal of Hg2+ by this moss is discussed.

(1990), Patterns of productivity in the finance literature: A study of the bibliometric distributions. Journal of Finance, 45 (1), 301-309. Full Text: J\J Fin45, 301.pdf Abstract: This study finds a bibliometric regularity in the finance literature that the number of authors publishing n papers is about 1/nc of those publishing one paper. We find that the finance literature conforms very well to the inverse square law (c = 2) if data are taken from a large collection of journals. When applied to individual finance journals, we find that values of c range from 1.95 to 3.26. We also find that top-rated journals have higher concentrations among their contributors. This implies that the phenomenon ßuccess breeds success” is more common in higher quality publications. ? Alexander, J.C. and Mabry, R.H.

Full Text: 1994\J Fin49, 697.pdf Abstract: We evaluate journals based on their relative contributions to top-level finance research in a recent period. Journals are ranked according to the number of citations found in articles published in Journal of Finance, Journal of Financial Economics, Journal of Financial and Quantitative Analysis, and Review of Financial Studies. The analysis controls for both the average number of articles and average number of words published annually in each cited journal. We identify the fifty most frequently cited journals during this period. We also list the fifty most frequently cited authors and articles and note topical trends in the research.

Journal of Finance, 49 (2), 713-725. Full Text: 1994\J Fin49, 713.pdf Abstract: This article uses the articles and citations from a set of eight finance journals to explore interjournal citation patterns, the research interests of individual journals, each journal’s influence in particular areas, areas of recent interest to finance, and the extent of interdisciplinary borrowing by finance. We find the following: two journals comprise the research core of finance research, most journals publish in a variety of research areas but are influential in a smaller number, a higher level of interest in financial markets than in corporate finance or financial institutions, and an overall low level of borrowing from outside disciplines.

Full Text: 1995\J Fin50, 1691.pdf Abstract: This study examines differences in finance research productivity and influence across 661 academic institutions over the five-year period from 1989 through 1993. We find that 40 institutions account for over 50 percent of all articles published by 16 leading journals over the five-year period; 66 institutions account for two-thirds of the articles. Influence is more skewed, with as few as 20 institutions accounting for 50 percent of all citations to articles in these journals. The number of publications and publication influence increase with faculty size and academic accreditation. Prestigious business schools are associated with high publication productivity and influence. ? Borokhovich, K.A., Bricker, R.J. and Simkins, B.J.

Full Text: 2000\J Fin55, 1457.pdf Abstract: This paper provides an analysis of the citation counts of articles published in the leading finance journals. It identifies the determinants of the most prevalent measure of influence for finance journals, the Social Sciences Citation Index impact factors. It finds that impact factors are affected by citations outside the finance field, are not affected by the distribution of published articles across subfields, and are good predictors of the long-term citation counts of articles. The citation impact factors are reduced for both the Journal of Financial Economics and The Journal of Finance by their publication of other than regular articles.
