Summary: Output gap revisions can be large even after many years. Real‐time reliability tests might therefore be sensitive to the choice of the final output gap vintage that the real‐time estimates are compared to. This is the case for the Federal Reserve's output gap. When accounting for revisions in response to the global financial crisis in the final output gap, the improvement in real‐time reliability since the mid‐1990s is much smaller than found by Edge and Rudd (Review of Economics and Statistics, 2016, 98(4), 785–791). The negative bias of real‐time estimates from the 1980s has disappeared, but the size of revisions continues to be as large as the output gap itself. We systematically analyse how the real‐time reliability assessment is affected through varying the final output gap vintage. We find that the largest changes are caused by output gap revisions after recessions. Economists revise their models in response to such events, leading to economically important revisions for not only the most recent years but also reaching back up to two decades. This might improve the understanding of past business cycle dynamics but decreases the reliability of real‐time output gaps ex post. [ABSTRACT FROM AUTHOR]

Background: Concerns exist about the survival and complication rates of highly constrained total knee arthroplasty (TKA) prostheses. The aims of this study were to determine if there were differences between the revision and complication rates of fully stabilized (FSTKA) and hinged (HTKA) TKA, when used in both primary and revision procedures. Methods: Survivorship of all highly constrained TKA prostheses implanted over a 17 year period were analysed by the Australian Orthopaedic Association National Joint Replacement Registry. The primary outcome measure was time to first revision using Kaplan Meier estimates of survivorship. Results: In the primary setting, the cumulative percent revision at 11 years was higher for HTKA than for FSTKA prostheses (P = 0.014). However, this finding was only significant for patient >75 years. In the revision setting, there were no differences in the revision rates for either category of prosthesis for any age group. For the indication of periarticular/periprosthetic fracture, HTKA resulted in a lower revision rate than FSTKA in both primary and revision cohorts. There were no differences in the rates of revision for infection and aseptic loosening for either prosthesis type in primary or revision settings. The revision risk for periprosthetic fracture was higher after HTKA prostheses. Conclusion: Both FSTKA and HTKA prostheses provide similar outcomes in primary and revision procedures except for the setting of periarticular/periprosthetic fracture, where a HTKA should be used. In elderly patients, a FSTKA prosthesis is recommended as the risk of periprosthetic fracture is higher with a HTKA. [ABSTRACT FROM AUTHOR]

The post‐forecast revision drift (PFRD), the phenomenon of delayed stock price reactions to analyst forecast revisions, is a well‐documented market anomaly. Prior research attributes PFRD to underreaction by investors to analyst forecast revisions. This study investigates the role of the analyst forecast revision process itself in the PFRD anomaly. Using a large sample of US firms, we confirm prior findings of a positive serial correlation (momentum) in individual analysts' revisions to their earnings forecasts and, based on both indirect and direct tests, document a positive association between this momentum and PFRD. Further analyses reveal that both the forecast revision momentum and PFRD vary in similar ways with respect to the nature of the news driving the revisions and the information environment. Collectively, our findings show that underreaction by individual analysts in the forecast revision process is an important contributor to the PFRD phenomenon. [ABSTRACT FROM AUTHOR]

The presence of the opal chimaera, Chimaera opalescens, is reported for the first time in the deep waters of the Azores, with the capture of four specimens by fishermen and the video recording of an additional five individuals. Species identification was supported by the 646 bp sequenced fragment of the mitochondrial gene cytochrome oxidase subunit I. Because C. opalescens is a recently recognised species that had been recurrently misidentified as rabbitfish, Chimaera monstrosa, the historical data of C. monstrosa in the Azores were reviewed to assess the possible presence of both Chimaera species in the region. Although several authors have reported the occurrence of C. monstrosa in the Azorean waters since the 1800s, the majority of these are based on only three specimens caught during the late 1800s. The investigation performed using literature and examination of the museum specimens still available concluded that the most likely scenario is that C. monstrosa is absent from the Azores and past records of that species in the region are most likely misidentifications of C. opalescens.

A taxonomic revision of wimple piranhas of the genus Catoprion is performed in combination with a molecular analysis using mtDNA. Molecular phylogenetic analyses of 49 specimens using genetic distances, conventional likelihood and four delimitation methods yielded two distinct lineages of Catoprion, with the morphological analyses of 198 specimens of Catoprion corroborating the molecular results. We provide a redescription of Catoprion mento, from the Paraguay, Orinoco, and tributaries of western Amazon basin, keeping Mylesinus macropterus as a junior synonym of C. mento, and the description of Catoprion absconditus n. sp., from the Amazon and Essequibo basins. C. absconditus n. sp. differs from C. mento by the presence of 86–94 perforated scales in the lateral line (vs. 65–86 scales) and the presence of 35–40 circumpeduncular scales (vs. 29–34 scales). The distribution of C. mento follows the Amazonas‐Paraguay‐Orinoco lowlands, whereas C. absconditus follows the eastern Amazon biogeographic pattern. [ABSTRACT FROM AUTHOR]

Summary: Canarium pilicarpum Daly, Raharim. & Federman is a recently described species of the genus Canarium L. endemic to Madagascar. It occurs mainly in the eastern humid forest and near the northern tip of Madagascar. For more than 60 years this species was part of Canarium madagascariense Engl., before Daly's recent revision of the genus Canarium in Madagascar. In this paper we present an overview and revision of the genus Canarium. A full description of Canarium pilicarpum is given with further information about the plant itself. [ABSTRACT FROM AUTHOR]

Since the first phylogenetic study of the order Batrachospermales, Batrachospermum was shown to be paraphyletic. Subsequently, sections of the genus have been methodically investigated using DNA sequences and morphology in order to propose new genera and delineate species. Batrachospermum section Turfosa is the last section with multiple species yet to be examined. New sequence data of specimens from Europe and the United States were combined with the sparse sequence data already available. Phylogenetic analyses using rbcL and COI‐5P sequences showed this section to be a well‐supported clade, distinct from Batrachospermum section Batrachospermum and its segregate genera. Section Turfosa is raised to the generic rank as Paludicola gen. nov. Substantial genetic variation within the genus was discovered and 12 species are recognized based on DNA sequence data as well as morphological characters and geographic distribution. The following morphological characters were applied to distinguish species: branching pattern (pseudodichotomous or irregular), whorl size (reduced or well developed), primary fascicles (curved or straight), spermatangia origin (primary or secondary fascicles), and carposporophyte arrangement (loose or dense). Previously published species were transferred to the new genus: P. turfosa, P. keratophyta, P. orthosticha, P. phangiae, and P. periploca. Seven new species are proposed as follows: P. groenbladii from Europe; P. communis, P. johnhallii, and P. leafensis from North America; and P. aquanigra, P. diamantinensis, and P. turfosiformis from Brazil. In addition, three unsequenced species in the section, P. bakarensis, P. gombakensis, and P. tapirensis, were transferred to the new genus. [ABSTRACT FROM AUTHOR]

Daptolestes Hull, 1962 is a small genus of distinctive, ornate robber flies (Asilidae) endemic to Australia, currently placed in the subfamily Brachyrhopalinae, containing three described species, D. limbipennis, D. nicholsoni and D. sergius. Adults of Daptolestes species (except D. sergius) have patterned wings, brown and yellow integumental colour and a waisted abdomen and could be mistaken for vespid wasps when foraging for insect prey on flowers. Here, we present a phylogeny based on a morphological survey of adult specimens. Based on the phylogenetic results, we provide a description and revised diagnosis for Daptolestes and describe four new species: D. leei Robinson & Yeates, sp. nov.D. bronteflavus Robinson & Yeates, sp. nov.D. feminategus Robinson & Yeates, sp. nov. and D. illusiolautus Robinson & Yeates, sp. nov. We also erect a new genus, Humorolethalis Robinson, Li & Yeates, gen. nov. to accommodate Dasypogon sergius Walker [=Daptolestes sergius (Walker)]. For all species of both genera, we illustrate external features of the adults and male and female terminalia. Key to all Daptolestes species. [ABSTRACT FROM AUTHOR]

Reticulohistiocytoses (RH) are rare and clinically heterogeneous histiocytic disorders of dermatological interest. Three clinical entities with superimposable histopathological features are currently considered, namely solitary reticulohistiocytoma, diffuse/generalized reticulohistiocytosis and multicentric reticulohistiocytosis. Although in the last decade, RH studies have only minimally progressed, histiocytosis research has advanced considerably: the prognostic and therapeutic importance of the clinical subclassification of histiocytosis patients as well as of the detection of genetic alterations in the genes of the ERK pathway has been highlighted. According to these insights, we previously reported the presence of molecular alteration RH and described a subset of patients with disseminated multisystem involvement lacking arthritis. In the present review, we aim to update and revise the knowledge regarding RH. We first reviewed their histopathological, immunophenotypical and ultrastructural features, discussed their histopathological differential diagnosis with other conditions characterized by infiltrates made of oncocytic or epithelioid cells (with special regard to Destombes–Rosai–Dorfman disease) and finally summarized the molecular landscape of RH. We therefore tried to adjust the clinical subclassification of Langerhans cell histiocytosis to the clinical phenotypes of RH, outlining five clinically different groups of patients. Finally, we reconsidered the clinical workflow to the evaluation of RH patients, in light of the 5 different clinical groups and discussed the different therapeutic approaches and the possible role of target inhibitors.

Radiostereometric analysis (RSA) is the most accurate method of measuring component migration using radiographs but is restricted to use in prospective studies. Ein‐Bild‐Roentgen‐analyze (EBRA)‐Cup can be used retrospectively, but its accuracy to measure component migration following revision is unknown. This study aimed to determine the accuracy of EBRA‐Cup measurements of uncemented acetabular component migration after revision total hip replacement (THR). The secondary aim was to compare the number of cases identified using EBRA‐Cup and RSA as having proximally migrated above and below 1 mm at 2 years postoperatively. EBRA‐Cup measurements were performed on plain antero‐posterior pelvic radiographs taken at the same time as RSA radiographs in a prospective cohort of 53 hips undergoing acetabular revision. At 2 years, the mean difference between the RSA and EBRA‐Cup measurements for 17 components used to treat pelvic discontinuity was 0.90 mm, significantly greater than the mean difference of 0.28 mm for 36 components without discontinuity (P =.0001). The mean difference between the RSA and EBRA‐Cup measurements at 2 years for hips that were reconstructed with an acetabular component alone, 0.28 mm, was significantly lower than hips that were reconstructed with an acetabular component in combination with an augment and/or cage, 0.74 mm (P =.0005). In conclusion, EBRA‐Cup can accurately measure migration of uncemented acetabular components used at revision THR. The presence of pelvic discontinuity, and addition of augments and cages, significantly influenced the accuracy of EBRA‐Cup measurements. EBRA‐Cup and RSA had good agreement on classification of components that migrated proximally above or below 1 mm at 2 years, with 100% sensitivity, and 87% specificity. [ABSTRACT FROM AUTHOR]

This paper proposes a class of games called revision games. In a revision game, players start with initially prepared actions, followed by a sequence of random revision opportunities until a predetermined deadline. In the course of revisions, players monitor each other's behavior. It is shown that players can cooperate and that their behavior under the optimal equilibrium is described by a simple differential equation. We present the necessary and sufficient conditions for cooperation to be sustained in revision games. We also present applications to the preopening activities in the stock exchange and to an electoral campaign. [ABSTRACT FROM AUTHOR]

We review the generic limits and classification of the little studied Australian fauna of the soldier fly subfamily Chiromyzinae. Among chiromyzines are many species that are confirmed agricultural pests of sugar cane, maize and grasses, including Inopus rubriceps (Macquart, 1847) that has been introduced in New Zealand and the United States. A taxonomic treatment is provided for the genera that occur in Australia, including illustrations and the first robust identification key. Several nomenclatural changes are made. The monotypic genera Archimyza Enderlein, 1921, and Stenimas Enderlein, 1921, are synonymised under Chiromyza Wiedemann, 1820, and the status of four species is revised: Inopus grandicornis (Hardy, 1920a) comb. nov. and Inopus longicornis (Hardy, 1924) comb. nov. are transferred from their previous position in Chiromyza; and Chiromyza australis (Macquart, 1850) stat. rev. and Chiromyza matruelis (Enderlein, 1921) stat. rev. are transferred from their previous position in Hylorops Enderlein, 1921, rendering Hylorops a monotypic genus, endemic to Chile. A total of 13 genera are now recognised in the Chiromyzinae, with four genera and 18 described species known from Australia. We also present the first record for New Zealand of the Australian species Boreoides tasmaniensis Bezzi, 1922, which was most likely accidentally introduced. [ABSTRACT FROM AUTHOR]

This manuscript describes predicted NMR shifts for the limonoid natural product xylogranatin F. The 1H and 13C NMR shifts of four diastereomers were evaluated by GIAO and hybrid DFT/parametric DU8+ methods. The results of the 1H and 13C NMR calculations for both the GIAO method and the DU8+ calculations suggest the revised structure that was recently reassigned by chemical synthesis. Furthermore, we show that while DU8+ provides superior accuracy with less computation time, GIAO points to the correct structure with more distinguishable data in this case study.

The thelypteroid fern genus Stegnogramma s.l. contains around 18–35 species and has a global, cross‐continental distribution ranging from tropical to temperate regions. Several genera and infrageneric sections have been recognized previously in Stegnogramma s.l., but their phylogenetic relationships are still unclear. In this study, we present a global phylogeny of Stegnogramma s.l. with the most comprehensive sampling to date and aim to pinpoint the phylogenetic positions of biogeographically and taxonomically important taxa. Based on the reconstructed historical biogeography and character evolution, we propose a new (infra)generic classification and discuss the diversification of Stegnogramma s.l. in a biogeographical context. New names or combinations are made for 12 (infra)species, including transferring the monotypic species of Craspedosorus to Leptogramma. Finally, we discuss a possible link between leaf architecture and ecological adaptation, and hypothesize that the increase in leaf dissection and free‐vein proportion is an adaptive feature to cool climates in Stegnogramma s.l.

Key Takeaways: In November 2019, the USEPA published the revisions to the Lead and Copper Rule with seemingly small changes that could have significant implications. The proposed revisions will require water systems to immediately prepare a lead service line (LSL) inventory and an LSL replacement plan. The proposal would expand the current public education requirements to include sampling for lead at schools and childcare facilities. The proposal would require Tier 1 notification of lead action level exceedances; it also would require active outreach to customers when lead service lines are replaced. [ABSTRACT FROM AUTHOR]

Purpose: Children may require the long‐term use of a central venous catheter (CVC) for treatment. Multiple revisions may be required when these catheters malfunction. We herein reported our experience of utilizing the fibrous sheath in tunnelled CVCs for the revision. Methods: A retrospective review was conducted from July 2008 to June 2018 on all children with the revision of tunnelled CVCs using the fibrous sheath. Results: Sixteen children underwent 31 revisions of a tunnelled CVC (16 Broviac/Hickman catheters, 15 Permcath for haemodialysis). The age ranged from 6 months to 16 years old (mean 3.8 years old). The indications for CVC revision included blockage (n = 14), breakage (n = 9) and dislodgement (n = 6). The mean time interval between CVC insertion and revision was 10.1 months (range: 20 days to 39 months). The fibrous sheath could be used for re‐insertion in 27 revisions (success rate: 87%). The failure was associated with the upsizing of the CVC (P =.003). In three of the four failed cases, a new CVC could be inserted by the cut‐down technique through the same venous access site. The overall success rate of CVC revision using the same venous access was 97%. There was no 30‐day postoperative infective complication. Conclusions: The fibrous sheath of tunnelled CVCs is a reliable access for CVC re‐insertion. This helps to preserve the same venous access site for repeated revision of CVCs. This is extremely important in those children who depend on long‐term CVC usage. [ABSTRACT FROM AUTHOR]

The first total synthesis of nominal harziane diterpenoid 1 is disclosed, whose spectral characteristics did not match those of the reported natural product. Stereochemical analysis and subsequent synthesis of the epimeric tertiary alcohol led to reassignment of configuration of the natural product as shown for 2. At the heart of the synthesis is an enyne cycloisomerization that sets a key quaternary stereocenter within a cyclobutane with high diastereocontrol. The route features strategies for the synthesis of the highly congested 6‐5‐7‐4 carbon skeleton characteristic of the caged harziane diterpenoids. [ABSTRACT FROM AUTHOR]

Hypostomus albopunctatus was described from the Rio Piracicaba, a tributary of the Rio Tietê, upper Rio Paraná basin. Nevertheless, specimens attributed to this species are commonly found throughout other river systems in the upper Rio Paraná basin and present varying degrees of morphological variation. A taxonomic review of H. albopunctatus based on large series of specimens from many localities throughout the upper Rio Paraná basin was carried out. Results support H. lexi, H. niger and H. scaphyceps as junior synonyms. Hypostomus albopunctatus differs from all congeners except H. heraldoi by having pectoral‐fin spine equal to or shorter than pelvic‐fin spine (v. longer); it differs from H. heraldoi by having white or light yellow spots on the body and fins (v. dark brown or black spots). Despite conspicuous variation related to the shape and size of the spots and snout morphology, both spot and snout patterns overlapped among the examined populations, thus this variation was inferred to be intraspecific within a widely distributed H. albopunctatus.

Bathynellidae is the neglected family of Bathynellacea, a groundwater group of crustaceans with 33 genera and 107 species described and almost half of them included in the 'catch‐all' genus Bathynella. Due to the morphological homogeneity of the species, the taxonomic uncertainties have accumulated over time. Therefore, to explore the phylogenetic relationships among taxa, a combined approach using morphological and molecular data is needed. In this paper, we performed a phylogenetic analysis based on partial sequences of COI and 18S including 30 species of Bathynellidae. This data set represents the most updated one, including a new genus and a new species (Altainella calcarata gen. n. sp. n.) of Bathynellidae described here from Altai Mountain (Russia). The new taxon presents a new type of sexual dimorphisms with a peculiar structure on the coxopod of the male thoracopod VII and also sexual dimorphism on the mandibular palp, as some species of the subfamily Gallobathynellinae. This is the first species of Bathynellidae that presents both variants of sexual dimorphism. The molecular phylogeny supports the morphology and the erection of the new genus and displays highly divergent genetic units corresponding to subfamilies, with the new genus closer to Bathynellinae genera than other subfamilies. With the description of this new species and its molecular characterization, the existence of the other genera beyond Bathynella is confirmed in Eurasia. [ABSTRACT FROM AUTHOR]

Background: Periprosthetic femur fractures (PFFs) following hip arthroplasty can lead to significant morbidity due to their impact on mobility and the need for surgery. Its incidence often measured by the prosthesis revision rate reported in joint replacement registries. However, many PFFs are also treated with prosthesis retention and internal fixation. Minimally displaced and stable fractures may be treated without surgery. Knowledge of the difference between the number of femoral revisions for PFF (well reported in registries) and the number of surgeries for PFF overall would allow us to estimate the overall surgical burden. This study aims to determine the number of post‐operative PFF in three hospitals and compare those treated with revision surgery to those PFF treated with internal fixation and femoral stem retention. By determining this difference, we can ascertain a more accurate estimate of the overall surgical burden of PFF. Method: Patients 50 years and older who sustained a post‐operative PFF between 1 January 2011 and 31 December 2017 at three public hospitals were extracted from hospital records. The number of revision procedures was compared to the number of re‐operations of any type. Results: There were 200 patients admitted for management of PFF. One hundred and forty‐three (71.5%) required an operation of which 67 (47%) were revision arthroplasty. Conclusion: The overall surgical burden of PFF is approximately twice that represented by the revision rate. [ABSTRACT FROM AUTHOR]

Pathway‐Complexity, hierarchische Organisation, Außer‐Equilibrium‐ und metastabile oder kinetisch gefangene Spezies sind Begriffe die in jüngsten, hochqualitativen Publikationen im Feld der supramolekularen Polymere häufig verwendet werden. Oftmals sind die Terminologien, die die verschiedenen Selbstassemblierungspfade, die beteiligten Spezies und deren Beziehung sowie relativen Stabilitäten zueinander beschreiben, nicht trivial. In der Literatur sind häufig verschiedene Begriffe und Klassifizierungen zu finden, in vielen Fällen jedoch ohne klare Definitionen oder Richtlinien wie sie zu benutzen sind oder wie sie experimentell unterschieden werden können. Ziel dieses Kurzaufsatzes ist es, die existierenden Konzepte mithilfe jüngster Literatur zu klassifizieren, differenzieren und zu korrelieren. Dadurch soll der Leser eine generelle Einsicht in thermodynamische und kinetische Aspekte komplexer supramolekularer Polymerisationsprozesse erhalten. Ein gutes Verständnis dieser Begriffe und Konzepte sollte dazu beitragen, neue, komplexe, funktionale Materialien zu erschaffen. [ABSTRACT FROM AUTHOR]

A systematic revision of the temnospondyl 'Metoposaurus' azerouali Dutuit from the Late Triassic of the Argana Basin (Western High Atlas, Morocco) is presented. The type material is redescribed in detail, and a preliminary phylogenetic analysis – the first one dealing with all metoposaurid species – is also conducted in order to test its position within the Metoposauridae. Our analysis places 'Metoposaurus' azerouali as sister‐taxon to Arganasaurus lyazidi in a robust clade supported by two unambiguous synapomorphies (bulge‐like tabular horn and exoccipital process visible in dorsal view) and two ambiguous synapomorphies (cultriform process of uniform width and subtriangular posterior Meckelian fenestra). We therefore propose the new combination Arganasaurus azerouali comb. nov. for the species 'M.' azerouali. Our analysis also confirms that the central Laurasian genus Metoposaurus is monophyletic but not the genus Koskinonodon, which deserves its own systematic revision. By consequent, the Late Triassic rich vertebrate fauna from the Argana Basin comprises the metoposauroid Almasaurus habazzi, the basal metoposaurid Dutuitosaurus ouazzoui, and the genus Arganasaurus which is represented by the type species A. lyazidi and A. azerouali comb. nov. Combined with the stratigraphical and geographical occurrences of the taxa, our phylogenetic analysis suggests that metoposaurids may have appeared during the Longobardian (late Ladinian) in central Pangea. Their diversification may be linked to the Carnian Pluvial Episode. At least, their extinction may have occurred during the Rhaetian because of the aridification of the climate and/or competition with amniotes. [ABSTRACT FROM AUTHOR]

Bangana sensu lato (s.l.) has a confusing taxonomic history and has been verified as non‐monophyletic based on molecular studies. However, although taxonomic revision of Bangana is urgently required, revision is pending as samples for all included species are not currently available. In this study, partial sequences of three nuclear (exon 3 of recombination activating protein 1, early growth response protein 2B gene, and interphotoreceptor retinoid binding protein gene) and two mitochondrial genes (cytochrome b and cytochrome oxidase subunit I) from 14 species of Bangana s.l. and 24 outgroup taxa were analyzed to clarify the phylogenetic relationships of Bangana s.l. Except for Gymnostomus ariza and Incisilabeo behri, our study indicated that the remaining species presently assigned to this grouping could be divided into three major clades, with the third clade being non‐monophyletic. Based on our molecular phylogenetic results, we propose that the clade consisting of Bangana s.l. species with interrupted postlabial grooves (which excludes the clade containing the type species of Bangana) should be recognized as a new genus, which we name Decorus herein. The distinguishing morphological characters for this new genus are presented in this manuscript. [ABSTRACT FROM AUTHOR]

Objective: To evaluate the mid‐term clinical and radiographic results of revision total hip arthroplasty (THA) using jumbo cups in Chinese patients. Methods: We retrospectively studied 61 patients (63 hips; 29 men [30 hips], 32 women [33 hips]) who underwent acetabular revision with jumbo cups between January 2001 and April 2016 at our institution. The mean age at the index operation was 59.4 ± 11.4 years. The mean body mass index of the patients was 24.9 ± 3.8 kg/m2. Clinical evaluation was determined using the Harris hip score preoperatively and at follow up. Major complications (including instability, sepsis, and revision of the femoral or acetabular component) were recorded. Radiographic measurements included inclination and anteversion angles of the acetabular components, and the vertical and horizontal distances of the centers of rotation (V‐COR and H‐COR, respectively). In the 42 patients with normal contralateral hip joints, the postoperative V‐COR and H‐COR were compared between right and left sides. Their improvement in leg‐length discrepancy (LLD) after revision THA was also evaluated. Cup survival was evaluated using the Kaplan–Meier analysis. Clinical and radiographic outcomes were analyzed. Results: Mean follow up was 5.7 years (2–16 years). At the latest follow‐up, the average Harris hip score (preoperative vs postoperative values) had improved from 46 to 83 (P < 0.001). No acetabular component was radiographically defined as loosened. Four hips (6.3%) had major complications: one hip was revised because of periprosthetic infection (at 3 months); one underwent femoral open reduction and internal fixation (with implant retention) because of a periprosthetic femoral fracture (at 13 months); one operated hip developed a deep infection (at 2.5 years), which was treated with antibiotics; one hip experienced recurrent dislocation (at 4.5 years). The average cup inclination angle was 40.8° ± 6.8° and the average anteversion angle was 14.9° ± 6.6°. Average V‐COR decreased from 29.7 ± 10.4 mm to 22.3 ± 7.6 mm (P < 0.001). The average postoperative H‐COR was 29.5 ± 3.7 mm compared with 30.8 ± 6.6 mm preoperatively (P = 0.145). Among the 42 patients with normal contralateral hips, the average postoperative V‐COR were 22.2 ± 8.3 mm (operated side) and 14.0 ± 3.7 mm (contralateral side) (P < 0.001). LLD improved from −16.8 ± 17.1 mm to −5.6 ± 11.8 mm (P < 0.001). When failure was defined as any reoperation involving the hip, the mean 16‐year hip survival was 96.8% (95% confidence interval [CI] 87.9%–99.2%). When defined as any hip reoperation or major complication, it was 92.7% (95%CI 81.2%–97.2%). Conclusion: Use of jumbo cups for revision THA resulted in excellent mid‐term cup survival and helped restore the COR. [ABSTRACT FROM AUTHOR]

Not all manuscripts are published following revision, which potentially wastes the time of editors, reviewers, and authors. To investigate the reasons for final rejection and whether these articles were finally published, we evaluated submissions to Obstetrics & Gynecology from January 2013 to December 2017. We found that, of 8,119 manuscripts submitted, 1,650 (20.3%) were invited for revision, of which 121 or 7.3% were ultimately rejected or withdrawn from publication after an invitation for revision. In multivariable analyses, manuscripts rejected after an invitation for revision were more likely to be original research and to have higher‐than‐average reviewer quality scores compared to those accepted after revision. Primary reasons for revision included data interpretation and analytical methods. Reasons for rejection after revision were generally modifiable, but over a third would have required a change to the original study design. Most rejected manuscripts following revision were published in another MEDLINE‐indexed obstetrics and gynaecology journal but usually with a lower impact factor than Obstetrics & Gynecology.

Summary: Haplopappus paucidentatus Phil. (Compositae: Astereae: Machaerantherinae) is described and illustrated in colour and with a black and white text figure. Cultivation and propagation are discussed, most stocks better maintained using cuttings or layering. It is not apparently available commercially, but could be searched for under the 'catch all' name of H. glutinosus. Haplopappus Cass. is now recognized as a South American genus, considerably smaller than originally conceived by Hall in his major revision. It consists of 56 species in three subgenera, the largest, subgenus Haplopappus, contains 2 sections, section Haplopappus containing H. paucidentatus and H. glutinosus Cass. within which it has been included in several treatments.

Background: The Birmingham Hip Resurfacing (BHR) system (Smith and Nephew) was developed as an alternative to conventional total joint replacement for younger, more active patients. Among other complications exists the risk for femoral component failure. The only marketed revision option for such a complication involves exchange of all components for a total replacement arthroplasty. This presents as a considerable and potentially unnecessary operative burden where revision of only the femoral prosthesis would suffice. We have analysed revision options for BHR in the context of periprosthetic femoral fractures with a stable acetabular component. Methods: Technical details of dual mobility hip systems available in Australia were collated and analysed to assess for potential 'off label' use with an existing BHR acetabular component. These data were then compared with the custom‐made Smith and Nephew dual mobility implant with respect to clearance and sizing. Results: Two dual mobility articulation modalities from two companies were identified as appropriate for potential usage with four products analysed in detail. These two demonstrated acceptable sizing and clearance measurements. Conclusion: Comparison between readily available dual mobility prostheses with custom‐made implants showed off label dual mobility prosthetic use to be a viable alternative for femoral‐only revisions with in situ BHR. Single component revision has several advantages which include: a less complex surgical procedure, shorter operative time, decreased blood loss and the expectation of resultant lower morbidity. Furthermore, this less complex revision surgery should give comparable results to that of primary total hip arthroplasty. [ABSTRACT FROM AUTHOR]

The following article elaborates on the need for the Other in order to delineate the self and one's identity, and the eternal psychological process of turning the Other into an enemy. A parallel process, which can be observed nowadays, leads to a disregard for the otherness of the Other that results in the blurring of identity and an internal loss of the differentiation of intrapsychic structures. Both psychological processes share a dehumanizing approach which leads to neurosis and alienation. In order to withstand these tendencies, a revision of analytical psychology's view of the psyche and of the practice of Jungian analysis is warranted: an alternative to the 'Fear of the Feminine' described by Erich Neumann in 1959. It is suggested that consciousness and unconsciousness intertwine but from a position of equality and reciprocity. Such an attitude does not inspire fear. Rather, it recognizes the need of one for the Other and the inevitability of this situation. Moreover, this need and interdependence on equal grounds nourish the wish to know the Other, to be aware of the differences, and yet, at the same time, to acknowledge how close the Other really is. Analytical psychological therapy based on this model stresses the power of the ego while also strengthening its capacity for introspection. [ABSTRACT FROM AUTHOR]

As part of the ongoing revision of the Eurocodes, the regulations in EN 1999‐1‐1 on the buckling of aluminium compression members were also subjected to a critical review. This resulted in the need to revise the regulations for non‐welded compression members and for longitudinally welded compression members. The introduction of a buckling class C for soft tempers and minor adjustments in the allocation of the individual alloys and tempers to buckling classes A and B can be understood as a fundamental change. The new allocation is presented and explained. The required buckling curve for non‐welded columns made of materials of buckling class C was introduced in prEN 1999‐1‐1. In this context, minor improvements have also been made to buckling curves A and B. The curves are presented and compared with the results of numerical investigations. The comparison is done graphically as well as statistically (based on EN 1990, Annex D). For the design provisions of longitudinally welded aluminium compression members, a more extensive revision was necessary. The design concept was revised and switched to the use of separate buckling curves which are presented here. These curves are also compared with the results of numerical investigations.

An updated list of all 27 species of aphelinids (Hymenoptera: Aphelinidae) in nine genera that have been identified or reported from South Korea, along with a dichotomous taxonomic key to separate them, is provided. Ten of the species are included in the EPPO 'Positive list of biological control agents widely used in the EPPO region' (which corresponds to Appendix 1 – Commercially used biological control agents – and to Appendix 2 – Successfully introduced classical biological control agents – of EPPO Standard PM 6/3, 2016 version). Five of these species are successfully used in classical biological control. Other species could be used in the EPPO region, or elsewhere in the world, in the future. [ABSTRACT FROM AUTHOR]

The taxonomy of pleurocarpous mosses has long been based on a few key characters such as the presence or absence of a single costa or the posture of the leaves. Molecular analyses performed in the past two decades have often challenged the traditional familial and generic delimitations, as these simple characters have evolved repeatedly. For nearly a century the genus Hypnum has been defined principally by the combination of falcate leaves with a short double costa, differentiated alar cells and the mostly procumbent growth form. Although several earlier treatments revealed the polyphyly of Hypnum in its traditional sense, none of them included a representative selection of the species on a worldwide basis. Therefore, we sampled most of the taxa that were attributed to the genus by the monographer H. Ando, and performed a molecular phylogenetic analysis using DNA sequence data from two chloroplast loci and the nuclear ribosomal ITS region. The outcome of this analysis was a revision of the phylogenetic affinities of these representative taxa; we also matched more than 15 molecularly defined lineages of Hypnum s.l. to morphological characters and solved several nomenclatural problems. Consequently, we suggest taxonomic and nomenclatural re‐arrangements, which encompass the vast majority of taxa attributed to Hypnum and do not contradict their known molecular affinities. We deliver additional support for some of the most recent delimitations of Hypnum s.l. but introduce new data to refute the proposals for the segregation of the genera Lignocariosa and Insomniella, which can be accommodated in the existing genera Pseudohygrohypnum and Calohypnum, respectively. Similarly, we dispute the inclusion of Hypnum sauteri in Anacamptodon and propose the establishment of a new genus for this species. Instead of placing Callicladium in the Hypnaceae and Jochenia in the Entodontaceae, respectively, we propose new families for these two genera. Finally, we propose three other new genera to accommodate (1) Hypnum circinale, (2) H. chrysogaster with H. subchrysogaster, and (3) H. dieckii, respectively. The main diagnostic features of Hypnum in earlier treatments are shown to represent broadly distributed homoplastic characters, correlated with adaptation to the habitat conditions, such as the moisture content.

The structural puzzle of amipurimycin, a peptidyl nucleoside antibiotic, is solved by total synthesis and X‐ray diffraction analysis, with the originally proposed configurations at C3′ and C8′ inverted and those at C6′, C2′′, and C3′′ corrected. A similar structural revision of the relevant miharamycins is proposed via chemical transformations and then validated by X‐ray diffraction analysis. The miharamycins bear an unusual trans‐fused dioxabicyclo[4.3.0]nonane sugar scaffold, which was previously assigned as being in the cis configuration. [ABSTRACT FROM AUTHOR]

Biomimetic epoxide‐opening cascades of polyepoxides enable the efficient and rapid construction of polyether frameworks. Herein, we show that the epoxide‐opening cascade cyclization that affords tetrahydrofuran products in acidic aqueous media produces tetrahydropyran (THP) in neutral water. THP formation proceeded by simply heating polyepoxides in neutral water and followed a different cyclization mode from those observed so far. The novel cascade cyclization in H2O was applied to the synthesis of a new nerolidol‐type sesquiterpenoid, resulting in revision of the proposed structure and determination of the absolute configuration.

Evolutionary relationships among cetaceans within the family Delphinidae have been difficult to resolve due to the high number of species and their relatively rapid radiation. This is the case for the dolphin species currently placed in the genus Lagenorhynchus, and their relations to Cephalorhynchus and Lissodelphis species. Phylogenetic relationships among these species have been investigated using multiple lines of evidence, and that evidence consistently suggests that the six species currently assigned to Lagenorhynchus do not form a monophyletic group. Here, we summarize findings from studies of morphology, genetics, historical biogeography, and acoustics that offer insight into the phylogenetics of these taxa. We present the taxonomic basis for revision of Lagenorhynchus, propose retention of Lagenorhynchus albirostris and reassignment of the remaining five species into other existing generic names, namely Leucopleurus acutus, Sagmatias australis, Sagmatias cruciger, Sagmatias obliquidens, and Sagmatias obscurus. Making these revisions now so that the taxonomy better reflects evolutionary relationships among these species will ensure that future studies include the most appropriate taxa for investigating the complex phylogenetic and systematic relationships among cetaceans. However, comprehensive analyses using multiple lines of evidence are still needed to clarify the phylogenetic relationships within and among the Lissodelphininae genera Cephalorhynchus, Lissodelphis, and Sagmatias.

In 1909, Ridley published Adelmeria characterized by its congested terminal inflorescence with large persistent floral bracts. All five species at some point placed in Adelmeria were synonymized in Alpinia by Loesener and subsequent authors. Several phylogenetic studies revealed that Alpinia is highly polyphyletic, suggesting that it should be split into several genera. In the present study, we sampled all five species initially placed in Adelmeria plus additional ones with a similar morphology. The combined analysis of the ITS and trnK/matK regions showed that these species formed a strongly supported monophyletic group inside the Alpinia eubractea clade of the tribe Alpinieae. Although not completely diagnostic, the following morphological characters separate Adelmeria from most of the species currently inside the Alpinia eubractea clade: bilobed ligules; congested inflorescences; utricular bracteoles; sessile flowers; crestless anthers; obovoid fruits. Considering this molecular and morphological evidence, the recognition of Adelmeria is highly justified. In this present paper, we reinstate the genus which is endemic to the Philippines and provide a comprehensive taxonomic revision including a discussion of the application of the name Elmeria. A key to nine species of Adelmeria, four of which (A. dicranochila, A. isarogensis, A. leonardoi, A. undulata) are new to science, is provided as well as full descriptions and preliminary conservation assessments. Interestingly, monoecy was observed in A. oblonga and reported for the first time for Adelmeria. Four lectotypes and one epitype are designated in this study. [ABSTRACT FROM AUTHOR]

The article refers to interim financial reports and their effect on analysts' earnings forecasts and revisions. The "adaptive expectations" model has a reaction coefficient to identify the size and direction of a market response to errors. Forecasting behavior includes how analysts use financial reports and time-series information to make revisions. Explanations of algebraic expressions for predicting one-quarter-ahead forecast revisions and two- and three-quarter-ahead forecast revisions are given. Significance of nonearnings information in forecasting, suggestion that time-series models need an autoregressive parameter, and the revision process that is shared by ARIMA, or Box-Jenkins forecasting, and adaptive expectations models are mentioned.

This paper employs a "transaction" data-base to study whether observed quote-revisions are consistent with those predicted by the adverse selection and inventory cost theories of the bid-ask spread. We find that actual quote-revisions are consistent with the theoretical prediction in only 25% of the cases. Furthermore, quote-revision patterns are found to be strongly dependent on the level of the outstanding spread and, to a lesser extent, on the transaction size. These systematic patterns, unrelated to the inventory cost and adverse selection theories, are consistent with the effect on quote-revisions of the limit order book and the minimum 1/8 price-change rule.

The article focuses on the development of portfolio management models, particularly regarding the revision process and methodology over finite time sets. An intertemporal transitionary model of portfolio management is derived through the extension of the previously cited Markowtiz-Sharpe paradigm. The underlying basis of the Markowitz-Sharpe model is reviewed along with description of the finite interval adaptations introduced. Empirical research of common stocks between 1957-1964 is also provided to evaluate the efficiency of the model.

Commented on is the acceptance of the policy by the executive and legislative branches of government. Also provided is a table that measures the before and after tax rates of return from investment by small firm under present and progressive tax rates.

Abstract: The first total syntheses of the bioactive cyclodepsipeptides ohmyungsamycin A and B are described. Key features of our synthesis include the concise preparation of a linear cyclization precursor that consists of N‐methyl amides and non‐proteinogenic amino acids, and its macrolactamization from a bent conformation. The proposed structure of ohmyungsamycin B was revised based on its synthesis. The cyclic core of the ohmyungsamycins was shown to be responsible for the excellent antituberculosis activity, and ohmyungsamycin variants with truncated chains were evaluated for their biological activity.

Background To consolidate the new classification model addressed to the allergic and hypersensitivity conditions according to the International Classification of Diseases ( ICD)-11 revision timeline, we here propose real-life application of quality assurance methodology to evaluate sensitivity and accuracy of the 'Anaphylaxis' subsection. Methods We applied field-testing methodology by analysing all the consecutive inpatients' files documented as allergies from the University Hospital of Montpellier electronic database for the period of 1 year. The files clinically validated as being anaphylaxis were manually blind-coded under ICD-10 and current ICD-11 beta draft. The correspondence of coding and the impressions regarding sensibility were evaluated. Results From all 2318 files related to allergic or hypersensitivity conditions, 673 had some of the anaphylaxis ICD-10 codes; 309 files (46%) from 209 patients had anaphylaxis and allergic or hypersensitivity comorbidities description. The correspondence between the two coders was perfect for 162 codes from all 309 entities (52.4%) (Cohen-kappa value 0.63) with the ICD-10 and for 221 codes (71.5%) (Cohen-kappa value 0.77) with the ICD-11. There was a high agreement regarding sensibility of the ICD-11 usability (Cohen-kappa value 0.75). Conclusion We here propose the first attempt of real-life application to validate the new ICD-11 'Anaphylaxis' subsection. Clearer was the improvement in accuracy reaching 71.5% of agreement when ICD-11 was used. By allowing all the relevant diagnostic terms for anaphylaxis to be included into the ICD-11 framework, WHO has recognized their importance not only to clinicians but also to epidemiologists, statisticians, healthcare planners and other stakeholders.

On 1 March 2018, a 14-year-old girl was found lifeless in a stream behind her high school after having consumed FCKDUP-a beverage containing 11.9% alcohol and sold in 568 mL cans-during her lunch hour. Following her death, the Canadian government took actions at ministerial and parliamentary levels by seeking experts' advice to better regulate highly sweetened alcoholic beverages, otherwise referred to as 'alcopops'. We suggest that the Canadian government uses the work surrounding the alcopop tragedy as an opportunity to make significant amendments and revisions of federal alcohol regulations.

We examine the informativeness of analyst forecast revisions that are directionally inconsistent with prior stock price movements (sign-inconsistent revisions). Sign-inconsistent revisions represent approximately one-half of the forecast revisions from 1995 through 2010. Our tests indicate that sign-inconsistent revisions are less informative than are sign-consistent revisions. Sign-inconsistent revisions are less likely to be closer to actual earnings realizations and they generate smaller stock price reactions. We also find evidence that sign-inconsistent revisions are associated with analysts' economic incentives to generate trading volume and their behavioural limitations related to information uncertainty. These results suggest that sign-inconsistent revisions do not necessarily benefit investors. [ABSTRACT FROM AUTHOR]

ABSTRACT The nature of science (NOS) as described by education scholars is a critical component of scientific literacy and includes both rational and social aspects taught best in an explicit and reflective manner. NOS is frequently tied to a critical contextual empiricism (CCE) framework for knowledge production. Central to CCE is that objectivity is attained only with an integration of the rational and social within a diverse community of scholars that is open to criticism. The field of sexual selection theory is ripe with opportunities to present NOS in an explicit and reflective context that promotes the understanding of knowledge production as simultaneously social and rational. We examined the presentation of sexual selection theory in college evolutionary biology textbooks to evaluate the extent to which textbooks demonstrate uptake of change in the field and use socially driven critique to present science as both social and rational. All of the textbooks incorporated new research in the field and some provided context about how and why the field has changed but not to the degree warranted by the rich literature available. We provide recommendations for the integration of NOS and social embeddedness of science, and posit that a portrayal of science as both social and rational has the potential to promote more inclusive science teaching and a more accurate representation of science.
