Sex pheromone components of an undescribed Choristoneura species (Lepidoptera: Tortricidae) on lodgepole pine in British Columbia

E11-tetradecenyl acetate (E11-14 OAc) and Z11-tetradecenyl acetate (Z11-14 OAc) are sex pheromone components of an undescribed, pine-feeding Choristoneura (C. n. sp. CPG=Prince George) in British Columbia. Compounds were identified by coupled gas chromatographic- electroantennographic (GC-EAD) and coupled gas chromatographic-mass spectroscopic (GC-MS) analyses, and were field tested near Prince George, B.C. A 65:35 blend of E11-14 OAc and Z11-14 OAc attracted as many male C. n. sp. CPG as did the most attractive virgin fema1es, suggesting that the natural sex pheromone has only two significant components. This two-component blend is suggested for detecting and monitoring C. n. sp. CPG populations

Ordinary Meaning and Corpus Linguistics

This Article discusses how corpus analysis, and similar empirically based methods of language study, can help inform judicial assessments about language meaning. We first briefly outline our view of legal language and interpretation in order to underscore the importance of the ordinary meaning doctrine, and thus the relevance of tools such as corpus analysis, to legal interpretation. Despite the heterogeneity of the judicial interpretive process, and the importance of the specific context relevant to the statute at issue, conventions of meaning that cut across contexts are a necessary aspect of legal interpretation. Because ordinary meaning must in some sense be generalizable across contexts, it would seem to be subject in some way to the empirical verification that corpus analysis can provide. We demonstrate the potential of corpus analysis through the study of two rather infamous cases in which the reviewing courts made various general claims about language meaning. In both cases, United States v. Costello and Smith v. United States, the courts made statements about language that are contradicted by corpus analysis. We also demonstrate the potential of corpus analysis through Hart’s no-vehicles-in-the-park hypothetical. A discussion of how to approach Hart’s hypothetical shows the potential but also the complexities of the kind of linguistic analyses required by such scenarios. Corpus linguistics can yield results that are relevant to legal interpretation, but performing the necessary analyses is complex and requires significant training in order to perform competently. We conclude that while it is doubtful that judges will themselves become proficient at corpus linguistics, they should be receptive to the expert testimony of corpus linguists in appropriate circumstances

New Information in Naturalistic Data Is Also Signalled by Pitch Movement: An Analysis from Monolingual English/Spanish and Bilingual Spanish Speakers

New Information in Naturalistic Data Is Also Signalled by Pitch Movement:  An Analysis from Monolingual English/Spanish and Bilingual Spanish SpeakersIn communication, speakers and listeners need ways to highlight certain information and relegate other information to the background. They also need to keep track of what information they (think they) have already communicated to the listener, and of the listeners' (supposed) knowledge of topics and referents. This knowledge and its layout in the utterance is commonly referred to as information structure, i.e., the degree to which propositions and referents are given or new. All languages have 'chosen' different ways to encode such information structure, for instance by modifying the pitch or intensity of the vocal signal or the order of words in a sentence. In this study, we assess whether the use of pitch to signal new information holds in typologically different languages such as English and Spanish by analyzing three population group monolingual California English speakers, bilingual speakers of English and Spanish from California (Chicano Spanish), and monolingual Mexican Spanish speakers from Mexico City. Our study goes beyond previous work in several respects. First, most current work is based on sentences just read or elicited in response to highly standardized and often somewhat artificial stimuli whose generalizability to more naturalistic settings may be questionable. We opted instead to use semidirected interviews whose more naturalistic setting provides data with a higher degree of authenticity. Second, in order to deal with the resulting higher degree of noise in the data as well as the inherent multifactoriality of the data, we are using state-of-the-art statistical methods to explore our data, namely generalized linear mixed-effects modeling, to accommodate speaker- and lexically-specific variability. Despite the noisy data, we find that contour tones including H+L or L+H sequences signal new information, and that items encoding new information also exhibit proportionally longer stressed vowels, than those encoding given information. We also find cross-dialectal variation between monolingual Mexican Spanish speakers on the one hand and monolingual English speakers and Chicanos on the other: Mexican Spanish speakers modify pitch contours less than monolingual English speakers, whereas the English patterns affect even the Spanish pronunciation of early bilinguals. Our findings, therefore, corroborate Gussenhoven's theory (2002) that some aspects of intonation are shared cross-linguistically (longer vowel length & higher pitch for new info), whereas others are encoded language-specifically and vary even across dialects (pitch excursion & the packaging of information structure)

A supraomohyoidal plexus block designed to avoid complications

Interscalene blocks of the brachial plexus are used for surgery of the shoulder and are frequently associated with complications such as temporary phrenic block, Horner syndrome or hematoma. To minimize the risk of these complications, we developed an approach that avoids medially directed needle advancement and favors spread to lateral regions only: the supraomohyoidal block. We tested this procedure in 11 cadavers fixed by Thiel's method. The insertion site is at the lateral margin of the sternocleidomastoid muscle at the level of the cricoid cartilage. The needle is inserted in the axis of the plexus with an angle of approximately 35° to the skin, and advanced in lateral and caudal direction. Distribution of solution was determined in ten cadavers after bilateral injection of colored solution (20 and 30ml) and followed by dissection. In an eleventh cadaver, computerized tomography and 3D reconstruction after radio contrast injection was performed. In additional five cadavers we performed Winnie's technique with bilateral injection (20 and 30ml).Concerning the supraomohyoidal block the injection mass reached the infraclavicular region surrounded all trunks of the brachial plexus in the supraclavicular region and the suprascapular nerve in all cases. The solution did not spread medially beyond the lateral margin of the anterior scalene muscle into the scalenovertebral triangle. Therefore, phrenic nerve, stellate ganglion, laryngeal nerve nor the vertebral artery were exposed to the injected solution. Distribution was comparable with the use of 20 and 30ml of solution. Injections on five cadavers performing the interscalene block of Winnie resulted in an extended spread medially to the anterior scalene muscle.We conclude that our method may be a preferred approach due to its safety, because no structures out of interest were reached. Solution of 20ml is suggested to be enough for a successful bloc
