1. Effects of vegetable production system on epigeal arthropod populations

Author

Hummel, Robert L., Walgenbach, James F., Hoyt, Greg D., and Kennedy, George G.

Subjects
*CONSERVATION tillage, *INTERCROPPING
Abstract

Populations of epigeal arthropods were monitored in vegetable production systems under varying degrees of sustainable agricultural practices in Fletcher, NC (USA). Two tillage types (conventional plow and disk, strip-tillage (ST)), two input approaches (chemically based, biologically based) and two cropping schedules (continuous tomato Lycopersicon esculentum Mill.], 3-year rotation of sweet corn [Zea mays L.]/cabbage [Brassica oleracea L.], cucumber [Cucumis sativus L.]/cabbage and tomato) were employed from 1995–1998. A second study with tomatoes was performed in 1997–1998 to separate effects of pesticide use, intercropping and herbicide application. Pitfall traps (48-h sample period) were used at ∼25-day intervals to monitor relative activity of carabid beetles (Coleoptera: Carabidae), staphylinid (Coleoptera: Staphylinidae) beetles and lycosid spiders (Araneidae: Lycosidae). Carabids and lycosids appeared to be more active in systems with ground cover. Trap catches of carabid species were not significantly affected by insecticide input, but trap catches of lycosids were lower in plots with conventional insecticide use. No consistent effect of tillage was found over time, although Scarites spp. were more active in minimally disturbed habitats in 1998. Two distinct patterns of seasonal activity were observed for carabid beetles and lycosid spiders. Ground cover generally enhanced abundance of carabids and lycosids, while tillage type, pesticide use and crop rotation had different effects. [Copyright &y& Elsevier]

2. Effects of production system on vegetable arthropods and their natural enemies

*SUSTAINABLE agriculture, *CONSERVATION tillage
Abstract

Populations of foliar insect pests and natural enemies were monitored in vegetable production systems incorporating varying degrees of sustainable practices in Fletcher, NC, USA. Two types of tillage (conventional plow and disk, strip-tillage), two input approaches (chemically-based, biologically-based) and two cropping schedules (continuous tomato (Lycopersicon esculentum Mill.), 3-year rotation of corn (Zea mays L.), cucumber (Cucumis sativus L.) and tomato) were employed from 1995 to 1998. Tomato pest pressure was relatively low in all years, resulting in a limited impact of production systems on potato aphid, Macrosiphum euphorbiae (Thomas) (Homoptera: Aphididae), and its associated parasitoids and predators. Thrips (Frankliniella spp. (Thysanoptera)) populations were significantly higher in the biological input treatments in 3 of 4 years. Lepidopterous (primarily Helicoverpa zea Boddie (Lepidoptera: Noctuidae)) damage on tomato was significantly higher in biological treatments in all years, damage by thrips and pentatomids (Hemiptera: Pentatomidae) increasing each year in the continuous tomato crop schedule. Most insect populations were significantly influenced by type of insecticide input or ground cover. Few population measurements were affected by tillage type. Foliar insect problems in commercial vegetable production may be associated predominantly with insecticide input (i.e. more damage with biologically based insecticides) and use of intercropping (i.e. more damage in systems with living mulch); however, the long term effects of tillage and crop rotation remain to be seen.

3. History of the department of surgery in Cincinnati

Author

Hummel, Robert P.

Subjects
*SURGERY, *HISTORY of medicine
Abstract

This narrative reviews the foundations and development of surgery in Cincinnati beginning with the surgical pioneers and the founding of the first medical institutions by Dr. Daniel Drake. The amalgamation of multiple medical schools resulted in university affiliation and a “full-time” chairman of surgery. The arrival of Dr. George Heuer and his Johns Hopkins group caused great turmoil but resulted in a strong department of surgery and residency program. Drs. Reid, Carter, and Altemeier succeeded Dr. Heuer and each contributed to the department’s growth and success. Dr. Josef E. Fischer became chairman of surgery in 1978 and led the department through difficult times to its greatest expansion and development—bringing to a department with an outstanding history and tradition the reforms and modernizations needed to take it into the 21st century. Dr. Fischer has now returned to Boston and Harvard and was succeeded by Dr. Jeffrey Matthews in 2001. Under his capable leadership the department of surgery at the University of Cincinnati seems assured of a bright future. [Copyright &y& Elsevier]

*SHORT-term memory, *VIDEO games, *JOB performance, *MAGNETIC resonance imaging, *HEART beat
Abstract

Breaks filled with different break activities often interrupt cognitive performance in everyday life. Previous studies have reported that both enhancing and deteriorating effects on challenging ongoing tasks such as working memory updating, depend on the type of break activity. However, neural mechanisms of these break-related alterations in working memory performance have not been studied, to date. Therefore, we conducted a brain imaging study to identify the neurobiological correlates of effects on the n-back working memory task related to different break activities. Before performing the n-back task in the magnetic resonance imaging (MRI) scanner, young adults were exposed to break activities in the MRI scanner involving (i) eyes-open resting, (ii) listening to music, and (iii) playing the video game "Angry Birds". Heart rate was measured by a pulse oximeter during the experiment. We found that increased heart rate during gaming as well as decreased relaxation levels after a video gaming break was related to poorer n-back task performance, as compared to listening to music. On the neural level, video gaming reduced supplementary motor area activation during working memory performance. These results may indicate that video gaming during a break may affect working memory performance by interfering with arousal state and frontal cognitive control functions. [ABSTRACT FROM AUTHOR]

Subjects
*SENSOR networks, *UNDERWATER acoustic communication, *WIRELESS communications, *WIRELESS sensor nodes, *ALGORITHM research
Abstract

Actuated sensor networks enabled by underwater acoustic communications can be efficiently used to sense over large marine expanses that are typically challenged by a paucity of resources (energy, communication bandwidth, number of sensor nodes). Many marine phenomena of interest admit sparse representations, which, coupled with actuation and cooperation, can compensate for being data starved. Herein, new methods of field reconstruction, target tracking, and exploration-exploitation are provided, which adopt sparse approximation, compressed sensing, and matrix completion algorithms. The needed underlying structure (sparsity/low-rank) is quite general. The unique constraints posed by underwater acoustic communications and vehicle kinematics are explicitly considered. Results show that solutions can be practically implemented, even over large ocean spaces. [ABSTRACT FROM PUBLISHER]

43. A Statewide Early Intervention Program for HIV-Infected People.

Author

Subjects
*AIDS, *HIV infections, *HOSPITAL case management services, *CLINICS, *PUBLIC health, *MEDICAL care
Abstract

Shortly after two federal agencies reported the value of prophylactic treatment for asymptomatic HIV-infected people in mid 1989, New Jersey augmented its hospital-based case management program to offer early intervention through live existing hospital outpatient clinics. It is also expected to reduce the need for beds to treat HIV-infected people in acute care institutions. Called the Treatment Assessment Program, New Jersey's early intervention initiative represents one example of the restructuring of health care services with several unique features that could be incorporated in any states. Although several other states have organized early intervention efforts, none has implemented a program with a common protocol of care accessible through-out the state. New Jersey's early intervention program offers HIV-infected people better access to life-sustaining drugs; provides for regular contact with counselors to improve client compliance with risk-reduction messages; allows participating clinics to become expert in prophylactic practice and serve as resources for the state's medical community; and assist the state in evaluation and long-term planning.

*HAND washing, *COLLEGE students, *MICROBIOLOGY
Abstract

Hand-washing behavior among students at a large regional university was observed. The authors noted how hand-washing behavior varied by race, gender, and having an observer present. Of the 410 subjects observed, most (221) were men and 232 were white. The authors expected that more women than men would wash their hands and that few subjects would wash their hands for the time (15 seconds or more) recommended by the American Society for Microbiology (ASM) and the Centers for Disease Control and Prevention (CDC). The data support both of these propositions. [ABSTRACT FROM AUTHOR]
