A replacement name for Dendrodus Olivier, 2008, and validation of Dendrochaetidae Olivier, 2008 nomen nudum (Acari: Prostigmata)
Authors: OLIVIER PIETER A. S.
Published: August 2019

The genus-group name Dendrodus Olivier, 2008 (Acari) is a junior homonym of Dendrodus Owen, 1841 (Pisces), and must be replaced. The family group name Dendrochaetidae Olivier, 2008 is unavailable because its type genus was not designated. The author hereby rectifies both problems by proposing the new genus name Dendrochaetus nom. nov. as a replacement for the preoccupied name Dendrodus Olivier, 2008. The author hereby also designates Dendrochaetus nom. nov. as type genus of Dendrochaetidae fam. nov. The description of Dendrochaetidae and diagnosis of the genus are as given by Olivier (2008).
Description of a new genus and two new species of killifish (Cyprinodontiformes: Nothobranchiidae) from West Africa, with a discussion of the taxonomic status of Aphyosemion maeseni Poll, 1941
Authors: SONNENBERG RAINER , BUSCH ECKHARD
Published: August 2019

The phylogeny of the West African genus Archiaphyosemion was studied with mitochondrial and nuclear DNA sequences. The results of the combined dataset presented here did not support a monophyletic group. After the exclusion of the type species of the genus, A. guineense, the remaining species form a well-supported monophyletic group. Based on these molecular results and supported by morphological data, we suggest a new name for this group, Nimbapanchax, new genus. Additionally, based on a recent collection in Guinea, two new Nimbapanchax species were described. The taxon Nimbapanchax leucopterygius, new species, is described for a nothobranchiid fish formerly misidentified as Archiaphyosemion maeseni (Poll, 1941). Nimbapanchax melanopterygius, new species, is described from the Mount Nimba region in southeastern Guinea. Both new Nimbapanchax species are clearly distinguished from their congeners by the coloration pattern of adult males. The results of the DNA data support the assumption based on color pattern and morphological characters that the new described species are sister taxa. The type of Aphyosemion maeseni Poll, 1941 was reexamined and transferred to the genus Epiplatys, a decision based on diagnostic morphological characters.

Extraordinary cranial specialization in a new genus of extinct duck (Aves: Anseriformes) from Kauai, Hawaiian Islands
Authors: IWANIUK ANDREW N. , OLSON STORRS L. , JAMES HELEN F.
Published: August 2019

Talpanas lippa is described as a new genus and species of waterfowl from Kauai, Hawaiian Islands, that is unlike any other known member of the order. It is characterized by a short, stout tarsometatarsus and a braincase that is shallow and wide relative to its length with very small orbits. In comparison with extant species, the optic foramen of Talpanas is remarkably small whereas the maxillo-mandibular foramen, which is the exit point of the trigeminal nerve, is grossly enlarged. Relative to skull length and foramen magnum area, the maxillo-mandibular foramen is one order of magnitude larger in cross-sectional area than that of extant Anseriformes. We conclude that Talpanas had reduced visual abilities, as reflected externally by its small orbits and optic foramen, and a grossly hypertrophied trigeminal foramen. Taken together, this suggests that Talpanas may have been more heavily reliant upon somatosensory (tactile) cues for foraging than any living species of bird. Pectoral elements are unknown, but the evident lack of keen eyesight suggests that the species was flightless, as were many other insular waterfowl.
The Southeast Asian genus Stedocys Ono, 1995 (Araneae: Scytodidae): first descriptions of female genitalia and a new species from China
Authors: LABARQUE FACUNDO M. , GRISMADO CRISTIAN J. , RAMÍREZ MARTÍN J. , YAN HENGMEI , GRISWOLD CHARLES E.
Published: August 2019

The genus Stedocys was known only from males. Here we describe the first females of the genus. Stedocys genitalia are atypical for Scytodidae. Males are distinguished by having the papal tarsus subequal or smaller than the tegulum, not prolonged apically, without prolateral blunt macrosetae; the tegulum long, inserted apically on the tarsus; embolus slightly shorter than bulb, aciculate distally, and females by lacking fovea or positioning ridges below the epigastric furrow, and by having an anterior epigynal pouch. In this contribution, we describe the female and redescribe the male of Stedocys leopoldi (Giltay, 1935), and describe male and female of Stedocys pagodas new species from China (Yunnan). The lack of a projection on the male palpal tarsus suggests that Stedocys is the sister group of all other genera of Scytodidae.

A key to the Chinese Oxycera species (19 spp.) is presented.
Taxonomic revision of the Pegomya meridiana species group (Diptera: Anthomyiidae) including natural enemies of invasive Hypericum spp. (Clusiaceae)
Authors: MICHELSEN VERNER
Published: August 2019

The Pegomya meridiana species group is established for three Palaearctic species that supposedly all as larvae attack seed-capsules of Hypericum spp. (Clusiaceae). Pegomya meridiana (Villeneuve) and P. provecta (Villeneuve) are widespread Eurasian species, while the third species, P. canariensis Michelsen, is endemic to the western Canary Islands. Synapomorphies for the Pegomya meridiana species group are most evident in the females: A laterally compressed oviscapt with blade-shaped cerci and a unique forward displacement of spiracles VI onto tergite V. Both sexes of P. provecta and P. canariensis are further lacking abdominal spiracles VII, a character state not previously reported from Anthomyiidae. An equally novel character state is the fusion of the cercal tips seen in female P. canariensis. The taxonomic part includes illustrated descriptions, specimen records, notes on distribution and biology, and an identification key to males and females. Females of P. provecta and P. canariensis are described for the first time. Hypericum perforatum L. and H. canariense L. are known as invasive weeds outside their natural ranges, and it is pointed out that species of the P. meridiana species group might be useful in the control of alien populations of these plants through their seed-feeding larvae.
Species limits in Pteruthius (Aves: Corvida) shrike-babblers: a comparison between the Biological and Phylogenetic Species Concepts
Authors: RHEINDT FRANK E. , EATON JAMES A.
Published: August 2019

The question of how to define a species continues to divide biologists. Meanwhile, the application of different species concepts has led to disparate taxonomic treatments that confound conservationists and other biologists. The most widely followed guidelines to species designation in avian and other vertebrate taxonomy are Ernst Mayr’s Biological Species Concept (BSC) and Joel Cracraft’s version of the Phylogenetic Species Concept (PSC). Although the BSC is considered to be more conservative in its assignment of species status, there is a lack of research demonstrating differences in taxonomic treatment between the BSC and the PSC with reference to a multi-taxon multi-trait study system. We examined the case of five traditionally recognized species of shrike-babbler (Pteruthius) that have recently been divided into 19 species under the PSC. Re-analyzing previous morphological and molecular data and adding new vocal data, we propose a BSC classification of 9 species. However, taking into consideration geographic gaps in the sampling regime, we contend that additional data will likely reduce discrepancies between the total numbers of species designated under the PSC and BSC. The current PSC species total is a likely overestimate owing to species diagnosis based on characters that erroneously appear to be unique to a taxon at low sample size. The current BSC species total as here proposed is a likely underestimate on account of the conservative designation of taxa as subspecies in equivocal cases, e.g. where BSC species status is potentially warranted but may be masked by insufficient data.
A new small Arthroleptis (Amphibia: Anura: Arthroleptidae) from the Liberian part of Mount Nimba, West Africa
Authors: RÖDEL MARK-OLIVER , DOUMBIA JOSEPH , JOHNSON ALEX T. , HILLERS ANNIKA
Published: August 2019

A new small West African Arthroleptis from the rainforest at the south-eastern tip of Mount Nimba, Liberia is described. The new species differs from all known congeners by the combination of a unique color pattern, a rounded canthal region and a completely smooth skin. The comparison of 592 base pairs of the mitochondrial 16S rRNA from the new species with Arthroleptis samples from all over West Africa, revealed genetic distances between 13.4–17.9%. From the morphologically similar A. aureoli the new species differed by 17.9%. Future research may reveal the necessity to establish a new genus for this peculiar new frog.

Authors: BEZDĚK JAN , BEENEN RON
Published: August 2019

The taxonomic position of the genus Yunnaniata Lopatin, 2009 is discussed based on material from Yunnan. In our opinion, the genus Yunnaniata should be classified in the section Capulites Ogloblin, 1936, and is very close to the genus Capula Jacobson, 1925. The description of Yunnaniata konstantinovi Lopatin, 2009 is extended including the description of the sexual dimorphism. The spermatheca is illustrated. A list of species classified in Capulites and an identification key to genera of Capulites are given.

Authors: AO WEIGUANG , ZHANG XUBO , ÁBRAHÁM LEVENTE , WANG XILI
Published: August 2019

According to the Catalog of the World Antlions by Stange (2004), six species of the genus Euroleon Esben-Petersen are reported worldwide, distributed mainly in the Palaearctic Region. Bao and Wang (2006) confirmed that Euroleon coreanus (Okamoto), 1926, Euroleon parvus Hölzel, 1972 and Euroleon polyspilus (Gerstaecker), 1885 occur in China. Euroleon sjostedti Navás, 1928 was discovered in China and denominated by Navás (1928) based on a single male specimen. This species has not again been reported anywhere until now.
The generic allocation of Hyla antoniiochoai De la Riva & Chaparro, 2005 (Anura), with description of its advertisement call and ecology
Authors: CATENAZZI ALESSANDRO , LEHR EDGAR
Published: August 2019

The description of the frog “Hyla” antoniiochoai is based on a subadult female and a juvenile collected in 2005 near Esperanza, Kosñipata Valley, Región (formerly Departamento) Cusco, southeastern Peru. The species was assigned to the genus Hyla (Hylidae) but could not be assigned to any species group within this genus. According to the original description, typical characters include the absence of webbing in hands, and vestigial webbing between Toes III and IV. In 2009, we collected additional specimens including adults of both sexes from the type locality. To our surprise these specimens show characters, such as a closed brood pouch, that are typical of Gastrotheca (Hemiphractidae). Furthermore, our analysis of the advertisement call supports its relation with Gastrotheca. Consequently, we assign “Hyla” antoniiochoai to Gastrotheca, compare it with its congeners, and improve the species diagnosis and description. Gastrotheca antoniiochoai lives in epiphytic bromeliads in the cloud forest and montane scrub between 2700 and 3300 m in Manu National Park. The new specimens were found inside bromeliads approximately 6–8 from the ground. It shares with the central Peruvian Gastrotheca zeugocystis, and the Venezuelan G. walkeri and G. williamsonii a lateral, paired brood pouch (instead of the single, dorsomedian pouch found in most Gastrotheca).

Published: August 2019

Integrated molecular and morphological studies of newly collected and curated specimens of the genus Caridina from the Atherton Tablelands, Wet Tropics World Heritage Area in north–eastern Queensland, Australia indicated the presence of an undescribed species belonging to the Caridina zebra Short 1993 complex. This species is somewhat intermediate, although distinct on the basis of molecular data and morphology, from two known sympatric species, Caridina zebra and C. confusa Choy & Marshall 1997, and an allopatric species, C. spinula Choy & Marshall 1997, from the Cape York Peninsula, about 500 km north. It is described here as a new species, C. malanda sp. nov., and compared with similar congeners. A key for the identification of the species, as well as notes on its distribution, ecology, and conservation, are provided.

Published: August 2019

In this study, the complete mitochondrial DNA sequence of Parum colligata (Lepidoptera: Sphingidae: Smerinthinae) was sequenced firstly. The mitogenome is 15,288 bp in size, containing 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), two ribosomal RNA genes (rRNAs), and an A+T-rich region. In the mitogenome, Ile, Leu2, and Phe are the most frequently used codon families, while codons GCG, TGC, GGC, CTG, AGG, and ACG are absent. The A+T-rich region is 358 bp in length including a motif ‘ATAGA’, an 18 bp poly-T stretch, three copies of a 12 bp ‘TATATATATATA’, and a short poly-A element. The nucleotides sequence of A+T-rich region is closer to Sphinginae than Macroglossinae. Phylogenetic analyses, based on the PCGs by using Maximum Likelihood (ML) and Bayesian Inference (BI) methods, generated consistent results that Smerinthinae was clustered together with Sphinginae to be the sister groups rather than Macroglossinae.
Two new species of Panaietis (Copepoda: Cyclopoida: Anthessiidae) associated with vetigastropods (Gastropoda) in coastal waters of southern Japan
Authors: UYENO DAISUKE
Published: August 2019

Two new species of the genus Panaietis (Copepoda: Cyclopoida: Anthessiidae) inhabiting the inside of the mouth cavities of marine snails are described from shallow waters of southern Japan. Panaietis bobocephala sp. nov. collected from the small abalone, Haliotis asinina (Vetigastropoda: Lepetellida: Haliotidae), is mainly characterized by the well-developed posterolateral corners of tergite on first pediger, the pointed spines on legs 1 to 5, the maxilla with two teeth, and the leg armature formula. Panaietis flavellata sp. nov. from Angaria neglecta (Vetigastropoda: Trochida: Angariidae) is characterized by the combination of following: leg 5 is situated on ventral side of the fifth pediger, inner margin of the second segment of antenna greatly protruded, and the leg armature formula.
Re-description of type material of Xenia Lamarck, 1816 (Octocorallia: Xeniidae)
Authors: HALÁSZ ANNA , MCFADDEN CATHERINE S. , TOONEN ROBERT , BENAYAHU YEHUDA
Published: August 2019

In this study we examined the original types of 21 of the 56 morphospecies of Xenia currently listed in WoRMS. Unfortunately, our attempts to locate additional type material failed, and we conclude that they have been lost. The type localities of the material examined include the Red Sea, West and Central Indian Ocean, the South Pacific, Indonesia, The Philippines, and the Bismarck Sea, reflecting the extensive biogeographical distribution of this genus throughout the Indo-Pacific Ocean. A neotype was designated from the northern Red Sea for X. umbellata, and sequencing established its position in the phylogenetic tree in relation to other genera of the family Xeniidae. In addition, X. flexibilis n. sp. was described from The Philippines. The findings from the current study led to the synonymizing of X. actuosa with X. sansibariana and of X. plicata with X. blumi. Overall, the study has re-described the types of 17 species considered to be valid based on morphological characters. Validation of the morphological features of original type material along with species-diagnostic genetic characters are required in order to facilitate our ability to correctly employ Latin binomials, both in phylogenetic studies and in any other biological surveys.

Paralebbeus pegasus sp. nov. is described from New Zealand and southeastern Australia, representing the first record of the genus from the temperate southwestern Pacific. The new species of Paralebbeus is unique in the genus for having meral spines on pereopods 3–5. A key to the species of Paralebbeus and global distribution map are provided.
Comments on the taxonomic validity of Camptodontornis yangi (Li, Gong, Zhang, Yang, and Hou, 2010) and its relationships to Longipteryx chaoyangensis Zhang, Zhou, Hou, and Gu, 2000 and Boluochia zhengi Zhou, 1995
Authors: YUN CHAN-GYU
Published: August 2019

Although the nomenclature of the longipterygid bird Camptodontus yangi Li, Gong, Zhang, Yang, and Hou, 2010 may have been clouded by the finding that its generic name was preoccupied by Camptodontus Dejean, 1826 in the carabid beetles, necessitating its replacement by Camptodontornis Demirjian, 2019, the taxonomic status of this species has become even more debatable.

Published: August 2019

We describe a new species, Moridilla jobeli sp. nov., belonging to the marine heterobranch group Aeolidioidea. Up to now, it is only recorded from Bunaken National Park, North Sulawesi, Indonesia. A combination of histological, computer tomographic and scanning electron microscopic methods was applied in order to describe and illustrate the anatomy of Moridilla jobeli sp. nov. in detail. Furthermore, we conducted molecular analyses which include available partial COI and 16S rRNA sequences, as well as the nuclear gene Histone 3 (H3) of Facelinidae and Aeolidiidae. NeighborNet analyses, species delimitation tests and phylogenetic reconstruction methods show the distinctiveness of the new species from the type species Moridilla brockii Bergh, 1888 and the two recently described species Moridilla fifo Carmona & Wilson, 2018 and Moridilla hermanita Carmona & Wilson, 2018, as well as the monophyly of the genus. A phylogenetic analysis of the Facelinidae and Aeolidiidae does not result in a resolved tree, therefore relationship of former assumed closely related genera, Noumeaella Risbec, 1937 and Palisa Edmunds, 1964, cannot be discussed in detail.

A poorly known Sichuan species, H. spatulata (Wu 1948) comb. nov. is transferred from Kiotina Klapálek, 1907 to Hemacroneuria, and an additional species known only from a female is reported by an informal designation. Aedeagal structures of Hemacroneuria males are described in detail for the first time and are useful for the separation of the genus from other genera of the Acroneuriinae. The taxonomic relationships of the new species are discussed.
Alburnus zagrosensis, a junior synonym of Alburnus sellal (Teleostei: Leuciscidae)
Authors: EAGDERI SOHEIL , NIKMEHR NASRIN , FREYHOF JÖRG
Published: August 2019

Morphometric, meristic and molecular (COI) characters of Alburnus zagrosensis, from the upper Karun River drainage in Iran, largely overlap or are identical with those of A. sellal, a species widely distributed in the Qweik River and the Persian Gulf basin, including the Karun River drainage. As no character states could be found to clearly distinguish these species, A. zagrosensis should be treated as a junior synonym of A. sellal.

A Simple Model of Convective Drafts Accounting for the Perturbation Pressure Term
Authors: Leger Julien , Lafore Jean-Philippe , Piriou Jean-Marcel , Guérémy Jean-François
Published: August 2019

A simple anelastic two-column model of convective updraft accounting explicitly for the perturbation pressure term is developed. There is no vertical wind shear in the environment, and two geometries (slab or axial) are possible. A shape factor is introduced to account for transport by a nonuniform horizontal profile of the vertical velocity in the updraft and its environment. The perturbation buoyancy profile being prescribed, three parameters must be prescribed: depth and aspect ratio of the updraft and the total cell size. The model is tested for idealized buoyancy profiles and evaluated against a large-eddy simulation of daytime development of deep convection. The model behavior agrees with our understanding of the perturbation pressure within clouds. The simulated updraft quickly responds to the buoyancy field (~5 min), shorter than the convection time scale, so that a steady model could be developed. Below the updraft core, a downward pressure gradient is simulated allowing the updraft to overcome a barrier of convective inhibition. This model is designed to be implemented in a convection scheme to replace classical drag formulations of the updraft model.

Published: August 2019

Screening rates for intimate partner violence (IPV) among most health care providers are low; yet, positive interactions with providers can benefit people who experience IPV, with respect to increased safety, support, and self-efficacy. Missing is a broad assessment and comparison of knowledge, attitudes, and behavior across the range of providers who are likely to be involved in a response to IPV disclosure. The purpose of our study was to assess health care providers’ IPV preparation, knowledge, opinions, and practices and examine differences across three types of health care providers (medical providers, nursing staff, and social/behavioral health providers). We used an anonymous online survey to gather self-reported information on preparation, knowledge, opinions, and practices around IPV. A random sample of 402 providers was drawn from 13 clinics in a large multispecialty outpatient practice setting. The respondents ( N = 204) consisted of medical providers ( n = 70), nursing staff ( n = 107), and social/behavioral health providers ( n = 27). Data analyses consisted of univariate, bivariate, and multivariate analyses. Social/behavioral health providers reported more preparation, knowledge, victim understanding, and less job-related constraints, yet they reported lower screening rates than medical providers and nursing staff. Overall, no provider group seemed well-equipped to work with patients who disclose IPV. Our findings identify unmet needs within our health system to better train health care providers and restructure care models to support IPV identification and response. A focus on interprofessional training and care collaboration would bolster competency and reduce constraints felt by the health care workforce.
Long-term Outcome in 7 Patients With Idiopathic Orbital Myositis
Authors: Matsuo Toshihiko
Published: August 2019

Purpose:

Idiopathic orbital myositis, a rare disease of unknown cause, presents a diagnostic puzzle because the diagnosis is based on the exclusion of other diseases. This study aims at elucidating its long-term outcome to answer a clinical question whether idiopathic orbital myositis would be a distinct clinical entity.

Methods:

Retrospective review was made on 7 consecutive patients (6 men and 1 woman) with the age at the initial visit ranging from 33 to 69 years (mean, 45.8 years) who were diagnosed with idiopathic orbital myositis and followed for 5 years or more (mean, 9.2 years) at a referral-based hospital.

Results:

Chief complaint at the initial visit was diplopia in 4 patients, blurred vision in 2 patients, and proptosis in 1 patient. On magnetic resonance imaging, 4 patients showed enlargement of a single extraocular muscle on unilateral side while 3 patients showed enlargement of multiple extraocular muscles on unilateral side or bilateral sides. No patient developed systemic diseases or other orbital lesions in the long-term follow-up. All patients at the last visit were free from symptoms, including diplopia, after tapering of prednisolone at the initial dose of 20 to 60 mg daily.

Conclusion:

Idiopathic orbital myositis had a favorable long-term outcome with corticosteroid administration and appears to be a distinct clinical entity without systemic involvement.

Aims

The aim of this study was to evaluate the effect of microsomal triglyceride transfer protein inhibitor (lomitapide) in patients with homozygous familial hypercholesterolaemia.

Methods and results

In 12 homozygous familial hypercholesterolaemia patients treated with lipid-lowering drugs ± biweekly lipoprotein apheresis sessions (nine patients), daily lomitapide was added. The lipid profile (total cholesterol, low-density lipoprotein cholesterol, triglycerides, high-density lipoprotein cholesterol) before and after lomitapide treatment was evaluated. The follow-up period with lomitapide treatment was 3–24 months (13.8 ± 7.9). The median baseline low-density lipoprotein cholesterol level was 900 mg/dl (348–1070), after lipid-lowering drugs therapy was 383.5 mg/dl (214–866) and after lipid-lowering drugs + time-averaged level was 288 mg/dl (183.7–716.6). The addition of lomitapide lowered low-density lipoprotein cholesterol levels further by 56.8% compared to lipid-lowering drugs alone (mean reduction 262, 95% confidence interval (105.5–418.7), p = 0.005) and by 54% (mean reduction 182.9, 95% confidence interval (−342 – −23), p = 0.031) comparing to lipid-lowering drugs + lipoprotein apheresis (time-averaged level). The time-averaged level of low-density lipoprotein cholesterol in lipid-lowering drugs + lipoprotein apheresis patients compared with lipid-lowering drugs + lomitapide was 54% in favour of lomitapide ( p = 0.031).

Conclusions

Treatment with lomitapide in homozygous familial hypercholesterolaemia patients has a beneficial effect with a constant decrease of low-density lipoprotein cholesterol by 57% compared with classical lipid-lowering therapy and by 54% compared with classical lipid-lowering therapy and time-averaged level of low-density lipoprotein cholesterol.
Informing thresholds for paediatric transfusion in Africa: the need for a trial

Published: August 2019

Background: Owing to inadequate supplies of donor blood for transfusion in sub-Saharan Africa (sSA) World Health Organization paediatric guidelines recommend restrictive transfusion practices, based on expert opinion. We examined whether survival amongst hospitalised children by admission haemoglobin and whether this was influenced by malaria infection and/or transfusion.

Methods: A retrospective analysis of standardised clinical digital records in an unselected population of children admitted to a rural hospital in Kenya over an 8-year period. We describe baseline parameters with respect to categories of anaemia and outcome (in-hospital death) by haemoglobin (Hb), malaria and transfusion status.

Results: Among 29,226 children, 1,143 (3.9%) had profound anaemia (Hb <4g/dl) and 3,469 (11.9%) had severe anaemia (Hb 4-6g/d). In-hospital mortality rate was 97/1,143 (8.5%) if Hb<4g/dl or 164/2,326 (7.1%) in those with severe anaemia (Hb ≥4.0-<6g/dl). Admission Hb <3g/dl was associated with higher risk of death versus those with higher Hbs (OR=2.41 (95%CI: 1.8 - 3.24; P<0.001), increasing to OR=6.36, (95%CI: 4.21–9.62; P<0.001) in malaria positive children. Conversely, mortality in non-malaria admissions was unrelated to Hb level. Transfusion was associated with a non-significant improvement in outcome if Hb<3g/dl (malaria-only) OR 0.72 (95%CI 0.29 - 1.78), albeit the number of cases were too few to show a statistical difference. For those with Hb levels above 4g/dl, mortality was significantly higher in those receiving a transfusion compared to the non-transfused group. For non-malarial cases, transfusion did not affect survival-status, irrespective of baseline Hb level compared to children who were not transfused at higher Hb levels.

Conclusion: Although severe anaemia is common among children admitted to hospital in sSA (~16%), our data do not indicate that outcome is improved by transfusion irrespective of malaria status. Given the limitations of observational studies, clinical trials investigating the role of transfusion in outcomes in children with severe anaemia are warranted.

Published: August 2019

A new identity involving a geometrically symmetric function and a differentiable function is established. Some new Fejér type integral inequalities, connected with the left part of Hermite–Hadamard type inequalities for geometrically-arithmetically convex functions, are presented by using the Hölder integral inequality and the notion of geometrically-arithmetically convexity. Applications of our results to special means of positive real numbers are given.

Bring a Friend! Privately or Publicly?
Authors: Carroni Elias , Pin Paolo , Righi Simone
Published: August 2019

We study the optimal referral strategy of a seller and its relationship with the type of communication channels among consumers. The seller faces a partially uninformed population of consumers, interconnected through a directed social network. In the network, the seller offers rewards to informed consumers (influencers) conditional on inducing purchases by uninformed consumers (influenced). Rewards are needed to bear a communication cost and to induce word of mouth (WOM) either privately (cost per contact) or publicly (fixed cost to inform all friends). From the seller’s viewpoint, eliciting Private WOM is more costly than eliciting Public WOM. We investigate (1) the incentives for the seller to move to a denser network, inducing either Private or Public WOM, and (2) the optimal mix between the two types of communication. A denser network is found to be always better not only for information diffusion but also for seller’s profits, as long as Private WOM is concerned. Differently, under Public WOM, the seller may prefer an environment with less competition between informed consumers, and the presence of highly connected influencers (hubs) is the main driver to make network density beneficial to profits. When the seller is able to discriminate between Private and Public WOM, the optimal strategy is to cheaply incentivize the more connected people to pass on the information publicly and then offer a high bonus for Private WOM.

Choosing Between Growth and Glory
Authors: Belenzon Sharon , Chatterji Aaron K. , Daley Brendan
Published: August 2019

Prior work has established that the financing environment can impact firm strategy. We argue that this influence can shape the earliest strategic choices of a new venture by creating a potential trade-off between two objectives: rapid growth and reaping the benefits of a positive reputation (glory). We leverage a simple reputation-building strategic choice—naming the firm after the founder (eponymy)—that is associated with superior profitability. Next, we argue via a formal model that the availability of/dependence on external financing can explain why high-growth firms are rarely eponymous. We find empirical support for the model’s predictions using a large data set of 1 million European firms. Eponymous firms grow considerably more slowly than similarly profitable firms. Moreover, eponymy varies in accordance with the firm’s financing environment in a pattern consistent with our model. We discuss implications for the literature on new-venture strategy.

Condition-Based Production Planning: Adjusting Production Rates to Balance Output and Failure Risk
Authors: uit het Broek Michiel A. J. , Teunter Ruud H. , de Jonge Bram , Veldman Jasper , Van Foreest Nicky D.
Published: August 2019

Problem Definition: Many production systems deteriorate over time as a result of load and stress caused by production. The deterioration rate of these systems typically depends on the production rate, implying that the equipment’s deterioration rate can be controlled by adjusting the production rate. We introduce the use of condition monitoring to dynamically adjust the production rate to minimize maintenance costs and maximize production revenues. We study a single-unit system for which the next maintenance action is scheduled upfront. Academic/Practical Relevance: Condition-based maintenance decisions are frequently seen in the literature. However, in many real-life systems, maintenance planning has limited flexibility and cannot be done last minute. As an alternative, we are the first to propose using condition information to optimize the production rate, which is a more flexible short-term decision. Methodology: We derive structural optimality results from the analysis of deterministic deterioration processes. A Markov decision process formulation of the problem is used to obtain numerical results for stochastic deterioration processes. Results: The structure of the optimal policy strongly depends on the (convex or concave) relation between the production rate and the corresponding deterioration rate. Condition-based production rate decisions result in significant cost savings (by up to 50%), achieved by better balancing the failure risk and production output. For several systems a win-win scenario is observed, with both reduced failure risk and increased expected total production. Furthermore, condition-based production rates increase robustness and lead to more stable profits and production output. Managerial Implications: Using condition information to dynamically adjust production rates provides opportunities to improve the operational performance of systems with production-dependent deterioration.
A low-cost intervention to promote immediate skin-to-skin contact and improve temperature regulation in Northern Uganda
Authors: Nissen Eva , Svensson Kristin , Mbalinda Scovia , Brimdyr Kajsa , Waiswa Peter , Odongkara Beatrice Mpora , Hjelmstedt Anna
Published: August 2019

Background

Uninterrupted skin-to-skin contact between mothers and newborns during the first hour after birth has been reported to be 2% in Uganda.

Aims

To investigate if a low-cost intervention targeting the behaviors of hospital staff would increase skin-to-skin contact and to investigate whether skin-to-skin contact stabilised temperature in the newborn.

Methods

The study had a quasi-experimental, before and after design. The sample included 110 in the pre-intervention group, and 93 in the post-intervention group. Data collection included observations of skin-to-skin contact and temperature measurements. Data were also collected from medical records and interviews.

Findings

No infants had skin-to-skin contact before the intervention, whereas the proportion was 54.8% after the intervention. Infants who received skin-to-skin contact (n=51) and infants who did not receive skin-to-skin contact (n=146) increased in temperature; however, infants who received skin-to-skin contact were significantly warmer after 5 minutes and remained so at 60 minutes.

Conclusions

The intervention increased the practice of skin-to-skin contact, which was found to be safe in regard to temperature stabilisation.
