Total evidence tip-dating phylogeny of platyrrhine primates and 27 well-justified fossil calibrations for primate divergences
Authors: de Vries Dorien , Beck Robin M. D. 
Published: October 2021

AbstractPhylogenies with estimates of divergence times are essential for investigating many evolutionary questions. In principle, “tip-dating” is arguably the most appropriate approach, with fossil and extant taxa analyzed together in a single analysis, and topology and divergence times estimated simultaneously. However, “node-dating” (as used in many molecular clock analyses), in which fossil evidence is used to calibrate the age of particular nodes a priori, will probably remain the dominant approach, due to various issues with analyzing morphological and molecular data together. Tip-dating may nevertheless play a key role in robustly identifying fossil taxa that can be used to inform node-dating calibrations. Here, we present tip-dating analyses of platyrrhine primates (so-called “New World monkeys”) based on a total evidence dataset of 418 morphological characters and 10.2 kb of DNA sequence data from 17 nuclear genes, combined from previous studies. The resultant analyses support a late Oligocene or early Miocene age for crown Platyrrhini (composite age estimate: 20.7-28.2 Ma). Other key findings include placement of the early Miocene putative cebidPanamacebusoutside crown Platyrrhini, equivocal support forProteropitheciabeing a pitheciine, and support for a clade comprising three subfossil platyrrhines from the Caribbean (Xenothrix,AntillothrixandParalouatta), related to Callicebinae. Based on these results and the available literature, we provide a list of 27 well-justified node calibrations for primate divergences, following best practices: 17 within Haplorhini, five within Strepsirrhini, one for crown Primates, and four for deeper divergences within Euarchontoglires. In each case, we provide a hard minimum bound, and for 23 of these we also provide a soft maximum bound and a suggested prior distribution. For each calibrated node, we provide the age of the oldest fossil of each daughter lineage that descends from it, which allows use of the “CladeAge” method for specifying priors on node ages.

The Dual Imaging and Diffraction (DIAD) beamline at Diamond Light Source is a new dual-beam instrument for full-field imaging/tomography and powder diffraction. This instrument provides the user community with the capability to dynamically image 2D and 3D complex structures and perform phase identification and/or strain mapping using micro-diffraction. The aim is to enable in situ and in operando experiments that require spatially correlated results from both techniques, by providing measurements from the same specimen location quasi-simultaneously. Using an unusual optical layout, DIAD has two independent beams originating from one source that operate in the medium energy range (7–38 keV) and are combined at one sample position. Here, either radiography or tomography can be performed using monochromatic or pink beam, with a 1.4 mm × 1.2 mm field of view and a feature resolution of 1.2 µm. Micro-diffraction is possible with a variable beam size between 13 µm × 4 µm and 50 µm × 50 µm. One key functionality of the beamline is image-guided diffraction, a setup in which the micro-diffraction beam can be scanned over the complete area of the imaging field-of-view. This moving beam setup enables the collection of location-specific information about the phase composition and/or strains at any given position within the image/tomography field of view. The dual beam design allows fast switching between imaging and diffraction mode without the need of complicated and time-consuming mode switches. Real-time selection of areas of interest for diffraction measurements as well as the simultaneous collection of both imaging and diffraction data of (irreversible) in situ and in operando experiments are possible.

Authors: Saddiq Abubakar Abubakar , Abu Bakar Abu Sufian 
Published: October 2021

Purpose
The purpose of this paper is to assess the perceptions of the grassroots on the impact of combative policy measures, strategies and programs introduced by the government and the civil society to reduce persistent occurrences of bribery practices in Nigeria.

Design/methodology/approach
Multi-stage or cluster sampling was used to acquire the data for this paper via survey questionnaire administered to the grassroots in Abuja, Nigeria. The data set is used to assess the impact of the various policy measures, strategies and programs on the persistence of bribery practices in Nigeria. The multiple linear regression method was used to estimate the data generated from 836 responses in Statistical Package for Social Sciences (SPSS) version 26.

Findings
The result of the estimations indicates that the respondents perceived that some of the policy measures, strategies and programs introduced have reduced persistence of bribery practices in Nigeria, whereas others have remained ineffective in reducing the persistence of bribery practices in Nigeria.

Originality/value
Previous studies on the impact of anti-bribery policy measures, strategies and programs were largely based on the perceptions of international institutions and business executives; this study appears to be the pioneer to focus on the perceptions of the grassroots in Abuja, Nigeria.
Can abusive supervision create positive work engagement? The interactive moderating role of positive causal attribution and workplace friendship
Authors: Huh Eunji , Lee Eun-Suk 
Published: October 2021

PurposeDeparting from previous research which shows that abusive supervision, as a salient job demand, induces detrimental employee outcomes, this study examines how to create constructive consequences of abusive supervision. To do so, the authors identify the boundary conditions to change the negative effect of supervisory abuse on employees’ work engagement in a positive direction. The authors examine the interactive moderating effect of a personal resource (i.e. positive causal attribution of abusive supervision) and a job resource (i.e. workplace friendship) on the relationship between abusive supervision and work engagement.Design/methodology/approachThe authors used data from a two-wave survey of 697 full-time workers with a time interval of one month and conducted three-way interaction analyses to test their hypothesized model.FindingsAbusive supervision increases employees’ work engagement when they make a positive causal attribution of abusive supervision (i.e. interpreting their abusive supervisor’s motives as promoting their job performance, rather than as intentionally harming them) and have favorable workplace friends.Originality/valueThe authors study offers a novel picture of abusive supervision by revealing that supervisory abuse can enhance employees’ work engagement when it is coupled with proper personal and job resources. In addition, this study highlights that in order to identify constructive effects of abusive supervision, it is critical to delve into the interaction between resources from these two domains to deal with abusive supervision.

AbstractWe have developed a polymerase chain reaction‐based method to detect and distinguish Mycobacterium leprae and Mycobacterium lepromatosis using a single set of primers based on a 45‐bp difference in the amplicon size of their rpoT gene. This method can also help in detecting the cases of co‐infection in a single experiment.
Towards a modular theory of trophic interactions

Published: October 2021

Abstract

Species traits and environmental conditions determine the occurrence and strength of trophic interactions. If we understand the relationship between these factors and trophic interactions, we can make more accurate predictions and build better trophic‐interaction models.

We can compare traits and conditions by considering their effect on different parts (steps) of a trophic interaction, such as the steps search and pursuit. By linking traits to relevant steps, we can use these relationships to build trophic‐interaction models. Currently, this is done ad hoc, defining steps based on the species and traits of interest. This makes it difficult to compare across traits and species and gain an overarching understanding of how traits and the environment drive trophic interactions.

We present a comprehensive approach for the explicit choice of interaction steps and species traits or environmental conditions, which is readily integrated into existing models. The core of this framework is that it is modular; we present eight steps that occur in all trophic interactions and use them to build a modular, general dynamic model. When applying the framework, one explicitly selects only the most relevant steps and uses those to build a specific model.

To build our modular framework, we revisit and expand the functional and numerical response functions, dividing the trophic interaction into eight steps: (1) search, (2) prey detection, (3) attack decision, (4) pursuit, (5) subjugation, (6) ingestion, (7) digestion and (8) nutrient allocation. Together these steps form a general dynamical model where trophic interactions can be explicitly parameterized for multiple traits and environmental factors. We then concretize this approach by outlining how a specific community can be modelled by selecting key modules (steps) and parameterizing them for relevant factors. This we exemplify for a community of terrestrial arthropods using empirical data on body size and temperature responses.

With species interactions at the core of community dynamics, our modular approach allows for quantification and comparisons of the importance of different steps, traits, and abiotic factors across ecosystems and trophic‐interaction types, and provides a powerful tool for trait‐based prediction of food‐web structure and dynamics.

ArsV and ArsW provide synergistic resistance to the antibiotic methylarsenite
Authors: Chen Jian , Zhang Jun , Wu Yi‐Fei , Zhao Fang‐Jie , Rosen Barry P. 
Published: October 2021

SummaryToxic organoarsenicals enter the environment from biogenic and anthropogenic activities such as microbial methylation of inorganic arsenic and pentavalent herbicides such as monosodium methylarsenate (MSMA or MAs(V)). Trivalent MAs(III) is considerably more toxic than arsenite or arsenate. Microbes have evolved mechanisms to detoxify organoarsenicals. We previously identified ArsV, a flavin‐linked monooxygenase and demonstrated that it confers resistance to methylarsenite by oxidation to methylarsenate. The arsV gene is usually in an arsenic resistance (ars) operon controlled by an ArsR repressor and adjacent to a methylarsenite efflux gene, either arsK or a gene for a putative transporter. Here we show that Paracoccus sp. SY oxidizes methylarsenite. It has an ars operon with three genes, arsR, arsV and a transport gene termed arsW. Heterologous expression of arsV in Escherichia coli conferred resistance to MAs(III), while arsW did not. Co‐expression of arsV and arsW increased resistance compared with either alone. The cells oxidized methylarsenite and accumulated less methylarsenate. Everted membrane vesicles from E. coli cells expressing arsW‐accumulated methylarsenate. We propose that ArsV is a monooxygenase that oxidizes methylarsenite to methylarsenate, which is extruded by ArsW, one of only a few known pentavalent organoarsenical efflux permeases, a novel pathway of organoarsenical resistance.

AbstractObjectiveTo determine the prevalence rates of frail, prefrail, robust and mobility disabled older adults living in retirement villages within regional Victoria, Australia.MethodsThis cross‐sectional, observational study invited residents of retirement villages to complete the self‐report questionnaires Fried Frailty Phenotype and Frail Non‐Disabled screening tool to classify respondents as frail, prefrail, robust and/or mobility disabled.ResultsFrom 212 respondents, prevalence rates of frail and prefrail status were 34% and 35%, respectively. A fifth (20%) of residents were mobility disabled. The prevalence of residents classified as frail or prefrail (ie, not robust) was higher in women (74%) than in men (58%). Classification as not robust increased with increasing age.ConclusionsThis study is the first to estimate prevalence rates of frailty and mobility disability in retirement village residents in regional Australia. Findings from this study have potential to inform the development of facilities and programs to support people living in this setting.

A c. 9720‐year history of a mountain lake–mire complex on the Shufan Plateau (southern Primorye, Russian Far East) is based on a multi‐proxy study of peat deposits. The chronology is based on eight radiocarbon dates in addition to two dated tephra horizons. The sediment contains eight cryptotephra layers attributable to Baitoushan, a volcano on the Korea/China border. Pollen, diatom and botanical macrofossil analyses indicate climate fluctuations during the Holocene and a compositional response of biodiverse mountain forests to changes in temperature and humidity. Widespread, diverse broadleaf‐dominated forest marked a warm Early Holocene (~9500–9280 cal. a BP). Korean pine (Pinus koraiensis) rose to dominance in the Middle Holocene (after c. 7630 cal. a BP). Evergreen conifers, fir (Abies) in particular, became widespread after 2.9 ka BP and show a positive response to the Little Ice Age cooling. Over the c. 10 000‐year record, moisture appears largely controlled by gradually declining intensity of the summer monsoon, trending from moist conditions in the Early Holocene to cooler and drier conditions in the Late Holocene with shorter‐term hydrological changes superimposed. Peat composition indicates significant changes in mire vegetation, and diatom assemblages indicate four stages of inundation and three dry stages in the basin, probably controlled by precipitation changes. The initial importance of atmospheric precipitation shifted over time to a greater input from groundwater. During a long episode in the Late Holocene the basin may have dried out. Forest fires occurred during much of the Middle and Late Holocene, and their prominence, as marked by macro‐charcoal, is related to changes in humidity. Human activities mark the past few centuries. Medieval fires were probably anthropogenic, and there is evidence of agricultural impact on the landscape during the Jin Empire settlement period 900–700 years ago and of more recent forest exploitation, particularly a reduction in conifer taxa.

Published: October 2021

AbstractObjectivesTo assess the clinical performance of an equine‐derived collagen‐containing bone block (CXBB) for lateral alveolar ridge augmentation and staged implant placement.Material and MethodsA total ofn = 16 patients (16 implants) had received a modified surgical protocol for lateral ridge augmentation using a size‐adapted rigidly fixed CXBB and contour augmentation. After 26 weeks of submerged healing, the primary endpoint was defined as the final ridge width (RW26) sufficient to place an adequately dimensioned titanium implant at the respective sites. Secondary outcomes included the gain in ridge width (RWg) and the need for secondary grafting. Clinical outcomes (bleeding on probing—BOP, probing depth—PD, and mucosal recession—MR) were assessed at implant loading and after a median observation period of 12.3 months.ResultsIn all patients (n = 16) investigated, RW26 allowed for a successful placement of an adequately dimensioned titanium implant at respective sites exhibiting mean RWg values of 5.09 ± 1.07 mm. A soft tissue dehiscence was noted in one patient (6.3%), and a secondary grafting was needed in two patients (12.5%) The changes in mean BOP, PD, and MR values at V9 amounted to 10.23 ± 30.11%, 0.14 ± 0.80 mm, and −0.01 ± 0.04 mm, respectively.ConclusionsCXBB may represent a feasible approach for lateral alveolar ridge augmentation and two‐stage implant placement.

AbstractBackground and purposeThe core manifestations of leucine‐rich glioma‐inactivated 1 (LGI1) autoantibody‐mediated encephalitis are limbic encephalitis and faciobrachial dystonic seizures. Agrypnia excitata (AE) is a rare syndrome characterized by sleep–wake cycle disruption, autonomic hyperactivation and episodes of oneiric stupor. Only a few diseases are known to present with AE. An autoimmune etiology must be considered when accompanied by neuromyotonia. A case of anti‐LGI1 encephalitis presenting with AE is reported.MethodsDetailed clinical, video‐polysomnographic, laboratory, radiological and long‐term follow‐up assessments were performed.ResultsA previously healthy 58‐year‐old man was referred for a rapidly progressive change in mental status, characterized by persistent drowsiness and confusion, accompanied by frequent episodes of unconscious gestures ranging from simple stereotyped movements to more complex actions mimicking various daily activities. Other symptoms included tachycardia, hyperhidrosis, mild hyponatremia, rare faciobrachial dystonic seizures, and a single generalized tonic–clonic seizure, but no neuromyotonia. Prolonged video‐polysomnography excluded epileptic activity and showed continuous monomorphic slowing of background activity not consistent with a regular wakefulness or sleep state. A brain magnetic resonance imaging scan was unremarkable. Brain fluorodeoxyglucose positron emission tomography revealed hypermetabolism of the hippocampi, amygdala and basal ganglia. Anti‐LGI1 antibodies were detected in the cerebrospinal fluid. The sleep disorder resolved progressively after starting immunotherapy.ConclusionsAgrypnia excitata can be a dominant, treatable manifestation of anti‐LGI1 encephalitis. Oneiric stupor episodes are a useful clinical feature for establishing diagnostic suspicion and could provide a window to understanding the mechanisms behind some movement disorders in autoimmune encephalitis.
