Improved high voltage insulator for use in vacuum

High voltage insulator for electron bombardment ion thruster has electric field directed through dielectric material and electrons emitted by field emission are constrained in negative junction region. Surface flashover and unstable operation are eliminated, and maximum voltage is limited only by dielectric strength of material, aluminum oxide in this case

Papal support for women under uncertainty: changing perceptions of women in religious leadership positions in the Roman Catholic Church

Women have historically been barred from holding positions of leadership and power. As a result, much of the literature examining women as leaders is narrow in context, focusing mainly on business and political settings (Eagly & Johnson, 1990). The current work contributes to diverse leadership research by analyzing women leaders in the context of the Roman Catholic Church - a historically gender-biased religious organization with no current leadership opportunities for women. The Church’s rigid leadership stance provides an optimal setting for exploring openness to accept change in traditionalist organizations. Previous research on identity leadership has shown that prototypical leaders are influential (Hogg & van Knippenberg, 2003) and that people are open to non-normative perspectives when they experience self-uncertainty (e.g., Gaffney et al., 2014; Rast et al., 2012). As a result, I hypothesized that under conditions of high uncertainty, Catholics would be most supportive of women in the priesthood when the Pope endorsed women as priests than when he did not. However, under low uncertainty, Catholics would be unsupportive of women in the priesthood regardless of the Pope’s endorsement. Additionally, I hypothesized that papal support of women in the priesthood would moderate the relationship between Catholic identification and support for women in priesthood. Two hundred forty-two Catholics participated in this experiment. Though neither hypothesis was supported, this research contributes to a lacking body of knowledge on women in diverse leadership roles, and explores how conservative organizations might ultimately accommodate change

Richness and Abundance of Carabidae and Staphylinidae (Coleoptera), in Northeastern Dairy Pastures Under Intensive Grazing

Dairy cattle has become popular to dairy farmers in the Northeast looking for management schemes to cut production costs. Carabidae (ground beetles) and Staphylinidae (rove beetles) are indicators of habitat disturbances, such as drainage of wetlands, or grassland for grazing animals, and their monitoring could provide one measure of ecosystem sustainability if intensive management systems expand or intensify in the future. Our objective was assess the abundance and species richness of these two beetle families under intensive grazing throughout Pennsylvania, southern New York and Vermont. We collected 4365 ground beetles (83 species) and 4,027 rove beetles (79 species) by pitfall traps in three years in Pennsylvania. Nine ground beetle species, Amara aenea, Poecilus chalcites, Pterostichus melanarius, Bembidion quadrimaculatum oppositum, Amara familiaris, Poecilus lucublandus, Agonum muelleri, Bembidion obtusum and Bembidion mimus represented 80% of the Carabidae collected. Five other species were new to Pennsylvania. Four rove beetle species, Philonthus cognatus, Meronera venustula, Amischa analis, and Philonthus various = (carbonarius), comprised 74% of the total Staphylinidae collected. Yearly distributions of the dominant species did not change significantly in the three years with A. aenea and P. cognatus being most abundant every year. A parasitic rove beetle, Aleochara tristis, was recovered for the first time in Pennsylvania and Vermont since its release in the 1960\u27s to control face fly, Musca autumnalis. Similar results were found in New York and Vermont. We collected 1,984 ground beetles (68 species). Pterostichus melanarius was most abundant. Pterostichus vernalis was detected for the first time in the United States (Vermont). It was previously reported from Montreal, Canada. We collected 843 rove beetles (45 species). Philonthus cognatus was the most abundant rove beetle. In addition, Tachinus corticinus, previously known only from Canada, was discovered for the first time in the United States in Vermont. Pastures in Pennsylvania were diverse, containing 14 species of forage plants and 17 weed species. Botanical composition was similar in New York and Vermont. Sixteen species of grasses and legumes made up 90% of the plant composition and 36 species of weeds made up the remainder. This di­verse plant ecosystem may explain the richness of ground and rove beetles in northeastern U.S. pastures because the heterogeneity in the plant population provided additional resources which can support a rich assemblage of beetles. Monitoring richness and abundance of Carabidae and Staphylinidae over three years in Pennsylvania suggests intensive grazing systems are eco­logically sustainable
