Stink Bugs in Florida Rice
No full textAlthough many different insects can be found in rice fields in Florida, stink bugs are currently considered the most important pest. Jones and Cherry reported that the rice stink bug was the dominant species, comprising more than 95% of the total stink bug population. Cherry et al. (1998) reported that the stink bug Oebalus ypsilongriseus was widespread in Florida rice fields. This was the first report of this species being found in commercial rice fields in the United States. Cherry and Nuessly (2010) reported that the stink bug Oebalus insularis is now widespread in Florida rice fields. This was the first report of this species being found in commercial rice fields in the United States. The stink bug complex attacking Florida rice is the most diversified and unique stink bug complex in US rice production. This 4-page fact sheet was written by Ron Cherry, and published by the UF Department of Entomology and Nematology, October 2013.

Sequential Sampling for Wireworms (Coleoptera: Elateridae) at Sugarcane Planting
No full textIn the Everglades Agricultural Area of Florida, where sugarcane is planted on around 410,000 acres annually, wireworms are the most economically important insect pests of newly planted sugarcane. This 3-page fact sheet provides a step-by-step plan to determine whether an application of soil insecticide may be needed to control wireworms. This publication is also a part of the Florida Sugarcane Handbook, an electronic publication of the Agronomy Department. Written by Matthew T. VanWeelden and Ron Cherry, and published by the Department of Entomology and Nematology, August 2016.

Abundance of Soil Insect Pests in Florida Sugarcane
No full textThis 6-page fact sheet written by Ron Cherry, Mabry McCray, Hardev Sandhu, and Michael Karounos and published by the UF/IFAS Entomology and Nematology Department is intended to inform sugarcane growers, scouts, pesticide applicators, and researchers about fluctuations of economically important sugarcane pests and implications for the management of those pests.

Silicon Effects on Resistance of St. Augustinegrass to Southern Chinch Bugs and Plant Disease
No full textSilicon (Si) is the second most common element on earth, but it is not considered an essential element for plant growth. However, a growing body of evidence has shown that Si can enhance plant resistance to insect pests. This 5-page fact sheet reports the results of a study to determine if silicon applications to St. Augustinegrass varieties increase the silicon in the plants and how this increased silicon affects development and survival of southern chinch bugs as well as development of plant diseases. Written by Alan L. Wright, Ron Cherry, Huangjun Lu, and Pamela Roberts, and published by the UF Department of Soil and Water Science, September 2013.

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
