The advances in, and diffusion of, technology have resulted in a growth of online educational opportunities. While programs public affairs are part this proliferation education, there is limited information on the current state education area. Using data collected from survey 96 National Association Schools Public Affairs Administration (NASPAA) affiliated institutions, exploratory study provides an overview landscape fields Master Policy (MPA/MPP). Areas studied include rationales for...

Flight potential, a poorly understood phenomenon in the migratory true armyworm, Pseudaletia unipuncta (Haworth), was investigated laboratory population using tethered-flight techniques. True armyworm exhibited strong flight potential relative to other known noctuids whose potentials were previously determined by similar generally low for 1-d-old moths and increased with age day 5 of adult life. speed distance flown decreased female from 10 as their reproductive system developed. The...

An adult population survey of four species the noctuid subfamily Plusiinae was conducted in soybean ecosystems south, south-central, and north-central Louisiana. Sticky traps baited with synthetic sex pheromone (Z)-7-dodecen-1-ol acetate were used as sampling tools for two growing seasons. The soy bean looper, Pseudoplusia includens (Walker), reached highest densities plusiinecomplex, five generations detected southern central regions state. Although Rachiplusia ou (Guenee) found to...

Academic institutions and programs are increasingly using experiential learning simulations with the observation that these pedagogical devices not only facilitate knowledge but they also provide an opportunity for skills attitudinal development. The article seeks to determine effect of through on students' Specifically, this examines whether participation in a Model United Nations (MUN) class affects self-reported development students from public university located southeastern States....

Collections of the sugarcane borer, Diatraea saccharalis (F.), from Brazil and Louisiana differ in morphology, physiology, behavior. These samples, along with one Mexico, were examined electrophoretically to aid determining basis this variation. Two other species, D. grandiosella Dyar lineolata (Walker), also examined. Genetic differences minor between Mexican samples (Nei's distance = 0.02) an order magnitude greater pairwise comparisons Brazilian sample (average 0.23). The collection was...

In the United States, local economic development is increasingly being managed by nonprofit organizations. However, institutional arrangement of an understudied topic in scholarly literature on management and leadership. This paper examines why communities select nonprofits to manage effect this has policy. We hypothesize that form government population size a community are variables affecting likelihood will organization for development. Additionally, we argue organizations differently than...

Drawing on the elaboration likelihood model of persuasive communication, authors examine impact perceptions instructor or source students' receptivity to a new substance abuse prevention curriculum. Using survey data from cohort students participating in Adolescent Substance Abuse Prevention Study, use structural equation modeling determine effects have their program measures targeted mediators and cigarettes, alcohol, marijuana. They test these after each component two-part curriculum is...

Although program recipients' attitudes toward instructors are crucial to outcomes, they have not been adequately examined in the substance abuse prevention literature. This study uses survey data explore of programming held by students from a national longitudinal evaluation school-based delivered Drug Abuse Resistance Education (D.A.R.E.) officers. Our analyses indicated that who had police officers as evaluated significantly higher than non-police instructors. The varied according...

The circadian rhythm releases of sex pheromone by Trichoplusia ni (Hübner) and Pseudoplusia includens (Walker) (Lepidoptera: Noctuidae) females were found to shift forward ca. 35 min 15 min, respectively, during the fast scotophase per °C decrease in conditioning temperature. However, with continuous exposure temperature, after 62 h (third scotophase), rhythms shifted original release times. T. have a lower minimal temperature for than P. . Observations third (62 test exposure) revealed an...

The metamorphosis of insects can, in a general way, be divided between those organisms that undergo pupation accompanied by cellular histolysis and gradually develop into adults without an intervening pupal stage development. In the former case, death cell population is integral part development tightly associated with massive DNA degradation during pupation. regard, it has been suggested uracil-containing acts as target for nucleolytic breakdown (Deutsch, W. A. (1987) Mutat. Res. 184,...

The epidermal, sex pheromone-producing cells in the eighth to ninth intersegmental region (ISR) are cuboidal columnar, and larger than non-ISR epidermal cells. ISR surface area is increased by microspines cuticular convolutions. No obvious ducts or pores occur cuticle. cuticle thinner that of anterior posterior regions. structurally differentiated at emergence Heliothis virescens. abdominal segment both species bears two heavily sclerotized valves. valves H. zea have more numerous longer setae do

Phase variation in cotton leafworm larvae was characterized using six color categories, ranging from green with yellow longitudinal bands to velvety black. A density-dependent relationship found between percentage of black and degree crowding field-collected larvae. Controlled experiments confirmed that affected larval phase variation. Exposure during the second third instar had greatest effect upon melanization expressed fifth instar. crowded reared under photoperiods LD 14:10 or 12:12 were...
