Persistence of Jack Pine Budworm \u3ci\u3eChoristoneura Pinus Pinus,\u3c/i\u3e (Lepidoptera: Tortricidae) Egg Mass Chorions on Jack Pine Foliage

More than one-fifth of old and nearly one-half of new jack pine budworm egg mass chorions remained on the foliage after one year, and an experienced observer could not determine accurately the age of one-fourth of them. Counts of new egg masses are used to estimate current populations, and large errors could result

Habitats and Spider Prey of \u3ci\u3eDipogon Sayi Sayi\u3c/i\u3e (Hymenoptera: Pompilidae) in Washington County, Maine

Spider wasps were reared from three types of trap-nests deployed in strip-clearcut areas of a spruce-fir-mixed hardwood forest of Maine. Collections of Dipogon sayi sayi from Mooseborn National Wildlife Refuge, Washington County, represent the easternmost records for the United States. Spider prey included females of Misumena vatia, Xysticus emertoni (new prey record), and X. punctatus, and juveniles and penultimate males of Xysticus sp. We found no evidence of nest-site competition between spider wasps and eumenid wasps (Hymenoptera: Eumenidae) that prey on spruce budwornl, Choristoneura fumiferana, when available nesting sites ranged from 320 to 4400

A Happiness Approach to Cost-Benefit Analysis

Subjective well-being (SWB) surveys ask respondents to quantify their overall or momentary happiness or life-satisfaction, or pose similar questions about other aspects of respondents\u27 mental states. A large empirical literature in economics and psychology has grown up around such surveys. Increasingly, too, scholars have advanced the normative proposal that SWB surveys be used for policymaking—for example, by using survey results to calculate monetary equivalents for nonmarket goods (to be incorporated in cost-benefit analysis), or to calculate gross national happiness. This Article skeptically evaluates the policy role of SWB data. It is critical to distinguish between (1) using SWB surveys as evidence of preference utility versus (2) using them as evidence of experience utility. Preference utility is a measure of the extent to which someone has realized her preferences; experience utility, a measure of the quality of someone\u27s mental states. The two are quite different because individuals can have preferences regarding non-mental occurrences. Having drawn this distinction, the Article then argues, first, that SWB surveys are poor evidence of preference utility—given problems of preference and scale heterogeneity, as well as other difficulties. Stated-preference surveys are a much better survey format for eliciting preference utility. Second, in considering SWB surveys as an experience-utility measure, we should recognize that experientialism about well-being—the view that well-being is simply a matter of good experiences—is highly controversial. More plausibly, an experience-utility measure might be seen as an indicator of one aspect of well-being. However, even constructing this weak experience-utility measure is not straightforward—as the Article demonstrates by discussing Daniel Kahneman\u27s detailed proposal for such a metric

Spruce Budworm and Other Lepidopterous Prey of Eumenid Wasps (Hymenoptera: Eumenidae) in Spruce-Fir Forests of Maine

Three species of eumenid wasps, Ancistrocerus adiabatus, Ancistrocerus antilope, and Euodynerus Ieucomelas, accepted and provisioned trap-nesting blocks with lepidopterous larvae, A pyralid. Nephopteryx sp., was the most commonly provisioned prey. A. adiabarus and E. leucomelas preyed on late instars of the spruce budworm, Choristoneura fumiferana: however. budworms accounted for only 6% of the provisioned prey. Estimates of budworm population densities before and after wasp predation, and subsample-s of provisioned prey indicated no significant reductions i = 0.065%) in budworm populations attributable to trap-nesting wasps

Comparison of catalyst activity

Reactions of highly active catalysts are compared by allowing temperature of catalyst bed, initially at 77 K, to increase slowly; marked deviation in smooth warming curve denotes temperature at which detectable reaction occurs. The lower the temperature at which reaction commences, the more active the catalyst

Terricolous Spiders (Araneae) of Insecticide-Treated Spruce-Fir Forests in West-Central Maine

Spiders of 12 families, 42 genera, and at least 62 species were captured in linear-pitfall traps placed in insecticide-treated (Sevin-4-Oil®, Dipel 4L ®, Thuricide 16B®) and untreated spruce-fIr forests of west-central Maine. Species richness per family ranged from 1 (Theridiidae, Araneidae, Salticidae) to 19 (Erigonidae). Most trapped species were web-spinners (67.2%); most trapped individuals were hunters (75.2%). Lycosidae accounted for 66.1 % of all (n = 887) captured spiders. Total trapped spiders varied among insecticide treatments, sampling dates, and study sites. However, comparison of mean prespray and postspray trap catches indicated no significant reduction (ANOVA, ANCOVA, P 0.05) in terricolous spiders following insecticide treatments. Increases in spider abundance during postspray sampling periods may have masked detection of treatment effects

Microstructure versus Size: Mechanical Properties of Electroplated Single Crystalline Cu Nanopillars

We report results of uniaxial compression experiments on single-crystalline Cu nanopillars with nonzero initial dislocation densities produced without focused ion beam (FIB). Remarkably, we find the same power-law size-driven strengthening as FIB-fabricated face-centered cubic micropillars. TEM analysis reveals that initial dislocation density in our FIB-less pillars and those produced by FIB are on the order of 10^(14)  m^(-2) suggesting that mechanical response of nanoscale crystals is a stronger function of initial microstructure than of size regardless of fabrication method

Low temperature catalytic ignition of hydrogen and oxygen

Catalyst composed of 32 percent iridium metal supported on granular alumina is most active and most stable of platinum metal catalysts. Catalyst consistently induces reactions at temperatures as low as 78 K

United We Ride National Dialogue

The Coordinating Council on Access and Mobility (CCAM) asked the National Academy of Public Administration and Easter Seals Project ACTION to develop and host the first United We Ride (UWR) National Dialogue. The goal of the Dialogue was to help shape future policy direction and provide input to the next CCAM strategic plan. The National Academy also assembled a small work group with representatives of the Federal Interagency Coordinating Council on Access and Mobility, Easter Seals Project ACTION, and the National Resource Center on Human Service Transportation to help guide the process of design and implementation.The CCAM includes 11 federal departments, nine of which are responsible for providing transportation for people with disabilities, older adults, and people with limited incomes. CCAM officially launched United We Ride in 2004 to (1) provide more rides for target populations while using the same or fewer assets, (2) simplify access, and (3) increase customer satisfaction.Key FindingsThe process used to create coordinated transportation plans needs improvement. Significant federal policy barriers still exist to strategies that would facilitate access to transportation services. Mobility management strategies are underutilized in communities across the country, and missed opportunities to bridge gaps between transportation and other community services still need to be addressed
