Seasonal Flight Patterns of Hemiptera in a North Carolina Black Walnut Plantation. 6. Tingidae and Aradidae
The seasonal flight patterns of II species of Tingidae and six species of Aradidae collected in window traps in a North Carolina black walnut plantation are described. Flying height distributions and seasonal flight activities of Corythucha ciliata (Say) and Gargaphia solani Heidemann are considered in detail
Seasonal Flight Patterns of Hemiptera (Excluding Miridae) in a Southern Illinois Black Walnut Plantation
The seasonal flight patterns of 99 species and subspecies of Hemiptera collected in window traps in a southern Illinois black walnut plantation are compared with similar data from a North Carolina black walnut plantation. Flying height distributions and seasonal flight activities of Corythucha juglandis, Orius insidiosus, Piesma cinerea, Acanthocephala terminalis, Alydus eurinus, Sehirus cinctus cinctus, Acrosternum hilare, Brochymena quadripustutata, Euschistus servus, and Euschistus variolarius are considered in detail
Annotated Bibliography of the Ambrosia Beetle \u3ci\u3eXylosandrus Germanus\u3c/i\u3e (Coleoptera: Scolytidae)
(excerpt)
Xylosandrus germanus (Blandford) (= Xyleborus germanus) is an ambrosia beetle that is found in Japan, Korea, the KurU Islands, Vietnam, China, Taiwan, central Europe, and the Cnited States (Nobuchi 1981). It attacks apparently healthy plants and those that are dying or recently dead (Weber 1982). Kaneko (1967) reported X. germanus to be a serious pest on tea (Thea sp.) plants in Japan, and Heidenreich (1%0) reported it on oak (Quercus sp.) trees in Gennany. This beetle seems to be increasing in economic importance on black walnut (Juglans nigra L.) and other hardwood species in the U.S. (Weber 1982)
Comparative Aspects of Mating Behavior Patterns in Six Species of Stink Bugs (Heteroptera: Pentatomidae)
Mating sequences were analyzed for six species of stink bugs using video- tapes. The results consisted of qualitative descriptions of the precopulatory activities of the pairs and quantitative analyses of the number and direction of mating sequences, including the latency to and duration of copulatory lock. It was possible to quantitatively characterize each of the six species tested. In addition, certain infrequent behavior patterns, e.g., head butts, were observed for some species and not others. The results extend the previous information on mating activities in stink bugs, particularly for Euschistus. We interpret our findings with regard to reproductive strategies in different species of stink bugs, and consider the use of behavior as a taxonomic tool
The Distribution of \u3ci\u3eXylosandrus Germanus\u3c/i\u3e in America North of Mexico (Coleoptera: Scolytidae)
Xylosandrus gemzanus (Blandford) (= Xyleborlus germanus), a sexually dimorphic beetle. was first described in 1894 from specimens collected in Japan; it is now also known from Korea. the Kuril Islands, Vietnam, China, Taiwan, central Europe, and the U.S. ( Sobuchi 1981)

Seasonal Flight Patterns of Miridae (Hemiptera) in a Southern Illinois Black Walnut Plantation
The seasonal flight patterns of 92 species of Miridae collected in window traps in a southern Illinois black walnut plantation are compared with similar data from a North Carolina black walnut plantation. Flying height distributions and seasonal flight activities of Amblytylus nasutus, Deraeocoris nebulosus, Leptopterna dolabrata, Lopidea heidemanni, Lygus lineolaris, and Plagiognathus politus are considered in detail. Six species are newly recorded for Illinois

A hybrid keyboard-guitar interface using capacitive touch sensing and physical modeling
This paper was presented at the 9th Sound and Music Computing Conference, Copenhagen, Denmark.This paper presents a hybrid interface based on a touch- sensing keyboard which gives detailed expressive control over a physically-modeled guitar. Physical modeling al- lows realistic guitar synthesis incorporating many expres- sive dimensions commonly employed by guitarists, includ- ing pluck strength and location, plectrum type, hand damp- ing and string bending. Often, when a physical model is used in performance, most control dimensions go unused when the interface fails to provide a way to intuitively con- trol them. Techniques as foundational as strumming lack a natural analog on the MIDI keyboard, and few digital controllers provide the independent control of pitch, vol- ume and timbre that even novice guitarists achieve. Our interface combines gestural aspects of keyboard and guitar playing. Most dimensions of guitar technique are control- lable polyphonically, some of them continuously within each note. Mappings are evaluated in a user study of key- boardists and guitarists, and the results demonstrate its playa- bility by performers of both instruments
Lighting the Fuse: Building regional identity through public library services in rural Central Appalachia
This presentation will relate survey and interview data that explore the perceptions and beliefs of librarians concerning the role of public libraries in fostering regional identity with a focus on libraries in rural Central Appalachia. As public libraries across the nation work to strengthen their connections to the communities they serve, the role of the library is being refined and redefined in relation to local needs and interests. During the past decade, the archival branch of librarianship has come to terms with the notion that by denying the inherently subjective nature of core archival duties such as acquisition, description, and providing access, archivists have been complicit in excluding the narratives of marginalized groups by preserving and perpetuating dominant historical, social, and cultural narratives. Often described as the ‘people’s university’, public libraries demonstrate a similar diligence in ensuring that their resources and services reflect the diversity of the communities they serve. Especially in the Appalachian region, where some believe that established narratives have often been constructed to support corporate and government agendas and can result in stigmatization of the region and its people, the public library can provide an important counterpoint to stereotypical portrayals that distort the image of Appalachian communities
