A new species of Pseudochalcura (Hymenoptera, Eucharitidae), with a review of antennal morphology from a phylogenetic perspective

Pseudochalcura alba Heraty & Heraty, sp. n. is described from Santiago del Estero and Catamarca provinces in northwestern Argentina. The male and female have long dorsal rami on all of the flagellomeres basal to the terminal segment, which is a unique feature within the genus and shared only with some species of Rhipipalloidea. Antennal modifications are compared across the Stilbula clade, of which all are parasitoids of Camponotini (Formicinae). A phylogenetic hypothesis for the group is proposed based on an analysis of 28S and 18S sequence data for 28 species. Ramose antennae are derived independently in both males and females across the clade, but with fully ramose female antennae restricted to the New World prolata group of Pseudochalcura and to some species of the Old World genus Rhipipalloidea. A sister group relationship between these genera is proposed based on both morphological and molecular data. Female antennae in other species of these genera, and other genera in the clade are at most dorsally lobate or serrate, but more commonly cylindrical. Monophyly of species of Obeza and Lophyrocera is supported and linked to a behavioral trait of ovi-position into fruits as opposed to flower heads or leaf buds. Within the Stilbula clade, a dichotomy between New and Old World taxa suggest relatively recent post-Miocene exchanges across the Northern Hemisphere.Fil: Heraty, John Michael.

Further information on the life of Charles Moore (1815-1881), Somerset geologist.

Copp et al. (1999) published an account of the life and work of Charles Moore, the Victorian amateur geologist whose fine collection is now held mainly by the Bath Royal Literary and Scientific Institution and the Somerset County Museum, Taunton. This note aims to amend and extend some information in that paper

An account of Mary Anning (1799-1847), fossil collector of Lyme Regis, Dorset, England, published by Henry Rowland Brown (1837-1921) in the second edition (1859) of Beauties of Lyme Regis

The publication of the now rare second edition of the guidebook The Beauties of Lyme Regis... by Lyme native Henry Rowland Brown (1837-1921) is dated to 1859. The known link of Brown’s family to Anning’s increases the significance of his book as a source for her, particularly the second edition which has a more extensive account of her than the first; relevant extracts are reproduced. His book has become a major source for writers on Anning, but only in corrupted form because of incompetent piracy by a later writer in a general magazine

An anonymous account of Mary Anning (1799-1847), fossil collector of Lyme Regis, Dorset, England, published in All the year round in 1865, and its attribution to Henry Stuart Fagan (1827-1890), schoolmaster, parson and author

An article on the fossil collector Mary Anning (1799-1847), published in All the Year Round in 1865, and much used in Anning literature, is usually ascribed to Charles Dickens. In fact it was by the Reverend Henry Stuart Fagan (1827-1890), grammar school headmaster, Church of England parson, and literary man. It is neither original nor reliable, and introduced errors into the Anning literature which are still problematic. The methodology of attribution of anonymous articles is discussed

CANreduce-SP—adding psychological support to web-based adherence-focused guided self-help for cannabis users: study protocol for a three-arm randomized control trial

Background: Cannabis is the most-frequently used illicit drug in Europe. Over the last few years in Spain, treatment demand has increased, yet most cannabis users do not seek treatment despite the related problems. A web-based self-help tool, like CANreduce 2.0, could help these users to control their consumption. Methods: This study protocol describes a three-arm randomized controlled trial (RCT) comparing the effectiveness of three approaches, in terms of reducing cannabis use among problematic cannabis users, the first two treatment arms including the Spanish version of CANreduce 2.0 (an adherence-focused, guidance-enhanced, web-based self-help tool) (1) with and (2) without psychological support; and the third group (3) treatment as usual (TAU). Study hypotheses will be tested concerning the primary outcome: change in the number of days of cannabis use over the previous week, comparing assessments at 6 weeks and 3 and 6 months follow-up between groups and against baseline. Secondary outcomes related to cannabis use will be tested similarly. Mental disorders will be explored as predictors of adherence and outcomes. Analyses will be performed on an intention-to-treat basis, then verified by complete case analyses. Discussion: This study will test how effective the Spanish version of CANreduce 2.0 (CANreduce-SP) is at reducing both the frequency and quantity of cannabis use in problematic users and whether adding psychological support increases its effectiveness. Trial registration: This trial is registered with the Clinical Trials Protocol Registration and Results System (PRS) number: NCT04517474 . Registered 18 August 2020, (Archived by archive.is https://archive.is/N1Y64 ). The project commenced in November 2020 and recruitment is anticipated to end by November 2022.

Mini-AFTERc: a controlled pilot trial of a nurse-led psychological intervention for fear of breast cancer recurrence

Funding: The study was funded by the Chief Scientist Ofce (CSO), which is part of the Scottish Government Health Directorates (reference: HIPS/17/57).Objectives   To determine the feasibility and acceptability of implementing the Mini-AFTERc intervention. Design   Non-randomised cluster-controlled pilot trial. Setting  Four NHS out-patient breast cancer centres in Scotland. Participants  Ninety-two women who had successfully completed primary treatment for breast cancer were screened for moderate levels of fear of cancer recurrence (FCR). Forty-five were eligible (17 intervention and 28 control) and 34 completed 3-month follow-up (15 intervention and 21 control). Intervention   Mini-AFTERc, a single brief (30 min) structured telephone discussion with a specialist breast cancer nurse (SBCN) trained to target the antecedents of FCR. Outcomes   Feasibility and acceptability of Mini-AFTERc and the study design were assessed via recruitment, consent, retention rates, patient outcomes (measured at baseline, 2, 4, and 12 weeks), and post-study interviews with participants and SBCNs, which were guided by Normalisation Process Theory. Results   Mini-AFTERc was acceptable to patients and SBCNs. SBCNs believe the implementation of Mini-AFTERc to be feasible and an extension of discussions that already happen routinely. SBCNs believe delivery, however, at the scale required would be challenging given current competing demands for their time. Recruitment was impacted by variability in the follow-up practices of cancer centres and COVID-19 lockdown. Consent and follow-up procedures worked well, and retention rates were high. Conclusions   The study provided invaluable information about the potential challenges and solutions for testing the Mini-AFTERc intervention more widely where limiting high FCR levels is an important goal following recovery from primary breast cancer treatment.Publisher PDFPeer reviewe

What is the evidence base for the assessment and management of cancer cachexia in adults with incurable pancreatic cancer? A rapid review

Cancer associated cachexia is a multifactorial disorder characterised by weight loss, and specifically the loss of muscle mass (with or without adipose tissue loss). It is distinct from malnutrition or starvation in that its effects may be partially, but not fully, reversed through nutritional support alone. It is associated with changes in muscle strength and results in progressive functional decline, treatment associated complications, worsening quality of life and cancer-related mortality. These cumulative effects are particularly relevant in pancreatic cancer, for which the majority of patients present with incurable disease and in which the rates of cancer cachexia are very high. Despite the well documented symptomatic and functional burdens - and associated implications for anticancer treatment receipt - there is very little structured assessment of cachexia by cancer Multidisciplinary Teams (MDT) and limited evidence on optimal interventions. International consensus driven guidelines have provided strong recommendations on a multidisciplinary and multimodal interventional approach to the assessment of cachexia and of the assessment and management of nutrition in cancer, whilst acknowledging that the levels of evidence for specific components is often moderate or low. The consensus guide-line on definition of cancer cachexia encourages assessment based on four domains: Storage (body composition, BMI, degree and rate of weight loss), Intake (nutritional assessment; symptom assessment for anorexia, nausea), Potential (evidence of catabolism e.g. CRP) and Performance. The rationale for this review is to examine the evidence base for the assessment and management of cancer cachexia specifically in pancreatic cancer where treatment intent is non-curative

Honesty, Lemons, and Symbolic Signals

Under asymmetric information, dishonest sellers lead to market unraveling in the lemons model. An additional cost of dishonesty is that language becomes cheap talk. We develop instead a model where people derive utility from actions (what they say), as well as from outcomes, so talk is costly. We find that the existence of honest agents that mean what they say is not enough to make trade more likely, unless a traceability condition that prevents arbitrage is met. When we introduce a continuum of misrepresentation cost types and qualities, full market unraveling is not possible and babbling equilibria are eliminated. More generally, costly talk is a special kind of signal, a symbolic signal that presupposes linguistic conventions, otherwise truth and falsehood, as well as misrepresentation costs, are undefined
