Three New Species of Sesioctonus Viereck (Hymenoptera, Braconidae, Agathidinae) from Peru

Three new species of Sesioctonus (Braconidae: Agathidinae) are described and illustrated, i.e., Sesioctonus huggerti, Sesioctonus wayquecha, and Sesioctonus bina. Two new Peruvian species records for Sesioctonus are reported: Sesioctonus longinoi and Sesioctonus diazi. A revised key to all known species of Sesioctonus is presented

School Sense of Community, Teacher Support, and Students\u2019 School Safety Perceptions

This study examined the association between two characteristics of school climate (sense of community and teacher support, measured both at the individual and at the school level) and students\u2019 feelings of being unsafe at school. The study involved a sample of 49,638 students aged 10\u201318 years who participated in the 2010\u20132012 California Healthy Kids Survey. Using hierarchical linear modeling (HLM), our findings revealed that, at the individual level, students perceiving higher levels of sense of community and teacher support at school were less likely to feel unsafe within the school environment. At the school level, sense of community was negatively associated with unsafe feelings, whereas there was no association between school-level teacher support and feelings of being unsafe at school

Autonomic physiological data associated with simulator discomfort

The development of a physiological monitoring capability for the Army's advanced helicopter simulator facility is reported. Additionally, preliminary physiological data is presented. Our objective was to demonstrate the sensitivity of physiological measures in this simulator to self-reported simulator sickness. The data suggested that heart period, hypergastria, and skin conductance level were more sensitive to simulator sickness than were vagal tone and normal electrogastric activity

Ten New Genera of \u3cem\u3eAgathidini\u3c/em\u3e (Hymenoptera, Braconidae, Agathidinae) from Southeast Asia

The Agathidini (Braconidae: Agathidinae) genera of Southeast Asia are revised based on a phylogenetic analysis of COI and 28S. Ten new genera are proposed, i.e., Agathigma, Asperagathis, Chimaeragathis, Cymagathis, Liragathis, Leuroagathis, Scabagathis, Trochantagathis, Xanthagathis, and Zosteragathis. An illustrated key to the Southeast Asian genera of this tribe is presented. Species from Thailand are keyed and described for all genera of Agathidini except Bassus and Zosteragathis which have too many species for this publication and will be dealt with separately. The phylogenetic analyses indicate that Bassus s.s. is polyphyletic. However, there are no morphological characters to support this and we have retained the current concept of Bassus, which is basically those Agathidini with simple tarsal claws. Numerous new combinations are proposed based on species that are moved to the newly erected genera

Impacts on the Electrical System Economics from Critical Design Factors of Wave Energy Converters and Arrays

It is expected that ultimately, like offshore wind farms, electrical systems will make up to a quarter of the overall Capex of wave farms. This is a significant element of cost and consideration must be taken in the design of both individual wave energy converters (WECs) and arrays of WECs to ensure that these costs can be minimised. In a worst case scenario design decisions could increase the cost of the electrical system by several orders and ultimately make the technology uncompetitive. This paper outlines the impacts on the cost of the electrical system arising from design factors of WECs and WEC arrays or wave farms. The paper uses a cost model to examine the impact to the cost of WEC array electrical systems caused by changing of key design factors. The design factors examined include WEC unit rating, capacity factor, interface to the electrical network, array spacing, export voltage, array design, site selection, export distance, and WEC dynamic response. All of these design factors have an impact on the economics of the electrical system and hence the economics of the wave farm as a whole. The paper concludes that there are some critical design choices which should be avoided if a cost-effective wave farm is to be established. It is also concluded that some design choices could ultimately reduce the overall Capex of WEC arrays enhancing their competiveness

\u3cem\u3eColemanus keeleyorum\u3c/em\u3e (Braconidae, Ichneutinae s. l.): A New Genus and Species of Eocene Wasp From the Green River Formation of Western North America

A new genus and species of Ichneutinae s. l., Colemanus keeleyorum Fisher, is described from the Eocene Green River Formation in Colorado, USA. Colemanus was placed on a phylogenetic hypothesis using morphological data. Using a parsimony criterion, Colemanus is placed within Proteropini (Ichneutinae s. l.). Reconstructions of well-preserved regions (mesosomal dorsum and wings) are included. A previously described species from lower Oligocene Baltic amber is transferred to Colemanus, resulting in the new combination C. contortus (Brues, 1933)
