When Is Product Personalization Profit-Enhancing? A Behavior-Based Discrimination Model
Authors: Laussel Didier , Resende Joana 
Published: March 2022

This paper investigates duopoly competition when horizontally differentiated firms are able to make personalized product-price offers to returning customers, within a behavior-based discrimination model. In the second period, firms can profile old customers according to their preferences, selling them targeted products at personalized prices. Product-price personalization (PP) allows firms to retain all old customers, eliminating second-period customer poaching. The overall profit effects of PP are shown to be ambiguous. In the second period, PP improves the matching between customers’ preferences and firms’ offers, but firms do not make any revenues in the rival’s turf. In the Bertrand outcome, second-period profits only increase for both firms if the size of their old turfs are not too different or initial products are not too differentiated. However, the additional second-period profits may be offset by lower first-period profits. PP is likely to increase firms’ overall discounted profits when consumers’ (firms’) discount factor is low (high) and firms’ initial products are exogenous and sufficiently different. When the location of initial products is endogenous, profits are hurt because of an additional location (strategic) effect aggravating head-to-head competition in the first period. Likewise, when a fraction of active consumers conceals their identity, PP increases second-period profits at the cost of aggressive first-period price competition. Finally, we show that the room for profitable PP enlarges considerably if firms rely on PP as an effective device to sustain tacit collusive outcomes, with firms credibly threatening to respond to first-period price deviations with second-period aggressive relocations of their standard products.

Formulaic Expressions for Foreign Language Learning and Teaching
Authors: Schmale Günter 
Published: March 2022

Foreign language teaching experts unanimously insist on the necessity of acquiring formulaic expressions in order to communicate successfully in the target language. However, many of the treatises in favour of phraseme use, including semantically non-compositional idiomatic expressions, by foreign language learners seem to be marked by an insufficient depth of reflection as to applied linguistic, methodological, and phraseodidactic[1] criteria. The present contribution therefore aims at a differentiated treatment of prefabricated communicative constructions, starting out from an extended definition and classification and by discussing the pros and cons of phraseme acquisition. These considerations will lead to the delimitation of formulaic language fundamental for an operative foreign language competence (routine formulae, collocations and “constructions”) as opposed to those types of phrasemes which are not essential or even inappropriate for non-native speakers.

Geschlechtsübergreifende Personenbezeichnungen in wissenschaftlichen Zeitschriftenartikeln
Authors: Toonen Jaron 
Published: March 2022

This study, based on a corpus of 20 Dutch and 20 German scientific journal articles, looks at how authors of German and Dutch research papers use nouns referring to persons. This investi-gation shows that although the two West Germanic languages are typologically similar due to their geographic proximity the two languages can vary a lot in terms of the abstraction (e. g. Lehrkräfte, Personen; leerkrachten, personen) and specification (e. g. Lehrerinnen und Lehrer; leraressen en leraren) of both grammatical gender and biological sex in academic articles. As a result it can be observed that Dutch authors prefer generic masculine personal nous whereas German authors tend to use more alternative forms, especially in recent times. The result contributes not only to a deeper understanding of personal nouns in academic articles but also to a clearer understanding of where and why there are differences between German and Dutch.

Published: March 2022

Fringe projection profilometry (FPP) is widely used in optical three-dimensional (3D) measurements because of its high stability. In FPP, fringe distortion is an inevitable and highly complex systematic error that significantly reduces the 3D measurement accuracy. At this point, the existing causes of fringe distortion represented by gamma distortion, high-order harmonics, and image saturation have been effectively analyzed and compensated to restore high-quality fringe images. In this paper, we innovatively reveal a concealed cause of fringe distortion, i.e., intensity diffusion across pixels, which is induced by photocarrier diffusion between photodiodes. To the best of our knowledge, intensity diffusion has not been studied in the field of fringe restoration. Based on the motion of photocarrier diffusion, we theoretically analyze the mechanism of how the intensity diffusion affects FPP. Subsequently, an intensity diffusion model is established for quantifying the diffused intensity in each pixel, and an intensity diffusion correction algorithm is presented to remove the diffused intensity from the fringe images and correct the fringe distortion. Experiments demonstrate the impact of intensity diffusion on FPP, and the 3D measurement results prove the effectiveness of the proposed methods on improving the 3D measurement accuracy by correcting the fringe distortion.

Published: March 2022

Background
Systemic pentavalent antimonials, mainly meglumine antimoniate, continue to be the first-choice drugs for treatment of cutaneous leishmaniasis (CL) despite their toxicity, difficulty of administration and high cost. In the search for therapeutic alternatives, combining two treatment interventions has emerged as a potential alternative to either reduce the use of antimonials with the associated toxicities, or to increase efficacy. Here, we report the results of a recently completed trial assessing the efficacy and safety of a combination of thermotherapy (TT) plus a short course of miltefosine (MLT) for the treatment of uncomplicated CL in Colombia and Peru.

Methods
A multicenter, randomized, evaluator-blinded, phase II, controled clinical trial was conducted. Adult volunteers with a parasitologically confirmed diagnosis of uncomplicated CL were randomly allocated to receive either a single session of TT or a combination of TT plus a short course of MLT (3 weeks). Therapeutic response outcomes and safety were assessed.

Results
130 subjects were included in the study, of whom 64 were randomly assigned to the TT arm and 66 to the TT + MLT arm. Cure at 3 months’ follow-up was achieved in 57.8% (n = 37) and 80.3% (n = 53) in the TT and TT + MLT groups, respectively, in the intention to treat analysis. The TT + MLT regimen was better that TT alone (p = 0.0055). The presence of vesicles at the site of heat application was the most common adverse event reported associated with the use of TT; while vomiting (31.8%) and elevation of liver enzymes (28.8%) were the most frequent adverse events reported associated with the use of MLT.

Conclusion
The combination of TT plus a short course of MLT was shown to be significantly better than TT alone for the treatment of uncomplicated CL in the New World.

Published: March 2022

BackgroundThe World Health Organization included burnout syndrome criteria that reduce both professional quality of life and work satisfaction in its 11th Revision of the International Classification of Diseases in 2019 while nursing bodies have issued action calls to prevent burnout syndrome. Despite this, the effect of social factors, personality traits and cross-interaction on professional quality of life is still unclear.AimTo reveal the association between ethical climate, personal trait and professional quality of life.MethodAn online survey of registered nurses working in adult, pediatric or both ICUs. We used the ten-item personality measure based on The Big Five theory and Type-D personality Scale-14 then measured the ethical climate with the Hospital Ethical Climate Survey and the professional domains of burnout syndrome, secondary traumatic stress and compassion satisfaction by the Professional Quality of Life Scale Version 5 simultaneously. Multivariate analysis confirmed the triangular association of hospital ethical climate, personality traits and professional quality of life.ResultWe enrolled 310 participants from September 2019 to February 2020. Mean age was 33.1 years (± 5.9) and about 70% were female. In the multivariate analysis, neuroticism (p = 0.03, p = 0.01) and Type D personality (both of p<0.01) were associated with burnout syndrome and secondary traumatic stress while agreeableness (p<0.01) was associated with secondary traumatic stress. Conversely, extraversion (p = 0.01), agreeableness (p<0.01) and openness (p<0.01) were associated with compassion satisfaction. We also observed interactions between hospital ethical climate and conscientiousness (p = 0.01) for burnout syndrome and secondary traumatic stress. Neuroticism was related to (p<0.01) BOS and compassion satisfaction while Type D personality (p<0.01) correlated with burnout syndrome and secondary traumatic stress.ConclusionHospital ethical climate strongly affects professional quality of life in nurses with specific personality traits. Therefore, it is important to maintain an ethical hospital climate, considering individual personalities to prevent burnout syndrome.
Evaluation of the effectiveness of combined staged surgical treatment in patients with keratoconus
Authors: Maharramov Polad M. , Aghayeva Fidan A. 
Published: March 2022

Purpose
This study performs comparative assessment of the results of different types of two-stage surgical treatment in patients with keratoconus, including combination of corneal collagen cross-linking with intrastromal corneal ring segments followed by topography-guided photorefractive keratectomy.

Materials and methods
Prospective review of 101 patients (101 eyes) with keratoconus was performed. Patients underwent corneal collagen cross-linking (32 patients), intrastromal corneal ring segments (48 patients), and a combination of these two procedures (21 patients). Transepithelial topography-guided photorefractive keratectomy was performed as the second stage of treatment in all patients with obtained stable refractive results at 8 months after first stage. Main outcome measures were visual acuity (uncorrected distance and corrected distance) and corneal topographic indices.

Results
Comparison of the studied parameters after first stage surgical treatment between non-combined CXL and combined groups demonstrated a statistically significant difference for uncorrected distance visual acuity, corrected distance visual acuity, and cylindrical refraction values (p<0.05). We observed significant improvement of visual acuity and key corneal topographic indices after topography-guided photorefractive keratectomy in all study groups (p<0.05). In 50 (49.5%) patients customized excimer laser ablation gave the possibility of full spherical and cylindrical corrections. Ten eyes (10%) had delayed epithelial healing, no corneal stromal opacities developed.

Conclusions
This study shows that combined two-stage surgical treatment of keratoconus, consisting of intrastromal corneal ring segment implantation with corneal collagen cross-linking followed by topography-guided photorefractive keratectomy, is clinically more effective to prevent keratectasia progression and increase visual acuity than the use of non-combined two-stage techniques.

Published: March 2022

Objective
The aim of the present study was to identify the factors associated with non-attendance of immediate postpartum glucose test using a machine learning algorithm following gestational diabetes mellitus (GDM) pregnancy.

Method
A retrospective cohort study of all GDM women (n = 607) for postpartum glucose test due between January 2016 and December 2019 at the George Eliot Hospital NHS Trust, UK.

Results
Sixty-five percent of women attended postpartum glucose test. Type 2 diabetes was diagnosed in 2.8% and 21.6% had persistent dysglycaemia at 6–13 weeks post-delivery. Those who did not attend postpartum glucose test seem to be younger, multiparous, obese, and continued to smoke during pregnancy. They also had higher fasting glucose at antenatal oral glucose tolerance test. Our machine learning algorithm predicted postpartum glucose non-attendance with an area under the receiver operating characteristic curve of 0.72. The model could achieve a sensitivity of 70% with 66% specificity at a risk score threshold of 0.46. A total of 233 (38.4%) women attended subsequent glucose test at least once within the first two years of delivery and 24% had dysglycaemia. Compared to women who attended postpartum glucose test, those who did not attend had higher conversion rate to type 2 diabetes (2.5% vs 11.4%; p = 0.005).

Conclusion
Postpartum screening following GDM is still poor. Women who did not attend postpartum screening appear to have higher metabolic risk and higher conversion to type 2 diabetes by two years post-delivery. Machine learning model can predict women who are unlikely to attend postpartum glucose test using simple antenatal factors. Enhanced, personalised education of these women may improve postpartum glucose screening.

Published: March 2022

Abstract

Objectives
The newborn screening (NBS) program in the Republic of Serbia has several decades of tradition, but it has not included any organic acidemias (OA). Therefore, this study aimed to establish the cut-offs of the corresponding NBS markers in the population of healthy newborns.

Methods
In dried blood samples (DBS) collected from 1,771 healthy newborns, we analyzed levels of propionylcarnitine (C3), isovalerylcarnitine (C5), and glutarylcarnitine (C5DC) using tandem mass spectrometry. Further we calculated the following ratios: C3/acetylcarnitine (C3/C2), C3/palmitoylcarnitine (C3/C16), C5/ free carnitine (C0), C5/C2, C5/C3, C5DC/octanoylcarnitine (C8), and C5DC/C0.

Results
The cut-offs for methylmalonic acidemia (MMA) or propionic acidemia (PA) were C3>5.73 μmol/L, C3/C2>0.23, and C3/C16>2.36. Based on the study findings, the screening results indicative for isovaleric acidemia (IVA) would include C5>0.372 μmol/L, C5/C0>0.020, C5/C2>0.019, and C5/C3>0.31. Finally, C5DC>0.303 μmol/L, C5DC/C8>7.1, and C5DC/C0>0.019 would justify further testing for glutaric acidemia type I (GA1). The cut-offs were satisfactorily validated via the comparison with worldwide estimates and data for several Caucasian populations.

Conclusions
The levels of the OA biomarkers in the Serbian population of healthy newborns have a distribution pattern similar to the other world populations. Therefore, the proposed cut-offs represent a reliable starting point for the future development of the OA NBS.
Enhancing the Utility of the Health and Retirement Study (HRS) to Identify Drivers of Rising Mortality Rates in the United States

Published: March 2022

Abstract
A recent report from the National Academies of Sciences, Engineering, and Medicine (NASEM) highlights rising rates of working-age mortality in the United States, portending troubling population health trends for this group as they age. The Health and Retirement Study (HRS) is an invaluable resource for researchers studying health and aging dynamics among Americans ages 50 and above and has strong potential to be used by researchers to provide insights about the drivers of rising U.S. mortality rates. This paper assesses the strengths and limitations of HRS data for identifying drivers of rising mortality rates in the U.S. and provides recommendations to enhance the utility of the HRS in this regard. Among our many recommendations, we encourage the HRS to prioritize the following: link cause of death information to respondents; reduce the age of eligibility for inclusion in the sample; increase the rural sample size; enhance the existing HRS Contextual Data Resource by incorporating longitudinal measures of structural determinants of health; develop additional data linkages to capture residential settings and characteristics across the life course; and add measures that capture drug use, gun ownership, and social media use.

London and Budapest: A Tale of Two Parliaments
Authors: Sisa József 
Published: March 2022

Abstract
The Houses of Parliament in London (1835–1860) and the Parliament in Budapest (1885– 1902) are related in many ways. It was due to former Prime Minister Gyula Andrássy’s personal commitment that a riverside site and the Neo-Gothic style were selected for the Hungarian edifice. While the New Palace of Westminster represents the late-medieval English variant of the Gothic style, its Hungarian counterpart is an amalgamation of various Gothic features marshalled into a heterogeneous synthesis. Inevitably the issue of a national style emerged, as well as the representation of royalty on the exterior and in the interior of the building. The Parliament in Budapest was meant tobe a national monument and project the (illusive) image of a Hungary on equal footing with the world’s major countries.
Somatic Depolarization Enhances Hippocampal CA1 Dendritic Spike Propagation and Distal Input-Driven Synaptic Plasticity
Authors: Bock Tobias , Negrean Adrian , Siegelbaum Steven A. 
Published: March 2022

Synaptic inputs that target distal regions of neuronal dendrites can often generate local dendritic spikes that can amplify synaptic depolarization, induce synaptic plasticity, and enhance neuronal output. However, distal dendritic spikes are subject to significant attenuation by dendritic cable properties, and often produce only a weak subthreshold depolarization of the soma. Nonetheless, such spikes have been implicated in memory storage, sensory perception and place field formation. How can such a weak somatic response produce such powerful behavioral effects? Here, we use dual dendritic and somatic recordings in acute hippocampal slices of male mice to reveal that dendritic spike propagation, but not spike initiation, is strongly enhanced when the somatic resting potential is depolarized, likely as a result of increased inactivation of A-type K+channels. Somatic depolarization also facilitates the induction of a form of dendritic spike driven heterosynaptic plasticity that enhances memory specificity. Thus, the effect of somatic membrane depolarization to enhance dendritic spike propagation and long-term synaptic plasticity is likely to play an important role in hippocampal-dependent spatial representations as well as learning and memory.SIGNIFICANCE STATEMENTNeurons receive synaptic input along their dendrites but produce action potential (AP) output at their soma. Signals arriving at the distal dendrites of pyramidal neurons (PNs) have little impact on the soma unless they combine to initiate a dendritic spike, which needs to propagate to the soma to trigger an AP. This study shows that small subthreshold depolarization of the soma powerfully enhances the propagation of dendritic spikes, through inactivation of dendritic A-type potassium channels. Enhanced dendritic spike propagation also markedly facilitates the induction of a form of plasticity driven by the distal synaptic inputs. Thus, small changes in somatic membrane potential, similar to those observedin vivo, act as a powerful gate of neuronal information transfer.

En este artículo presentamos los topónimos de la cuenca del río Tambopata en la región de Puno. Constituye solo una parte del estudio más amplio que hemos realizado sobre el léxico de nombres de lugares, plantas, animales, enfermedades y objetos recogidos en la cuenca del río Tambopata que comprende en su recorrido a tres distritos de la Prov. de Sandia: Yanahuaya, San Juan del oro y Putina Punco. Se analizó lingüísticamente (fonología, léxico y semántica) la variación de los nombres que están relacionados con la lengua que hablan en la zona. Así mismo, se aplicó la teoría de la variación dialectal y el método de geografía lingüística o geolingüística para levantar isoglosas, con un enfoque descriptivo – interpretativo inspirado en la lingüística estructural y funcional.
Se ha probado la hipótesis planteada, que el abandono de la lengua y cultura es lenta. El objetivo del estudio es mostrar la dialectalización del aimara y los patrones de denotación y connotación. Este estudio servirá para elaborar la cartografía lingüística, diccionarios regionales. Así también contribuirá con el conocimiento de los saberes andinos que está presente en este avance cultural, asimismo fortalecerá la interculturalidad.
