Smartphone Trading Technology, Investor Behavior, and Mutual Fund Performance
Authors: Cen Xiao 
Published: November 2023

Using proprietary individual-level trading data around a natural experiment—the release of a smartphone trading app by a large investment advisor—this study investigates how smartphone trading technology affects retail investor behavior and mutual fund performance. App adoption by retail investors leads to an increase in investor attention and trading volume. App adopters’ flows become more sensitive to short-term fund returns and market sentiment, resulting in higher aggregate flow volume among adopters. The funds more exposed to the shock experience a greater decline in abnormal returns, likely attributable to higher fund flow volume and liquidity costs. As a result, both adopters and nonadopters experience a decline in their mutual fund investment returns. This paper was accepted by Lin William Cong, finance. Funding: The W.

Reconstructing highly divergent wavefronts from sparse measurements
Authors: Berlakovich Nikolaus , Csencsics Ernst , Senoner Damian , Schitter Georg 
Published: November 2023

The paper presents a concept for the sparse measurement and reconstruction of highly divergent wavefronts enabling measurements at high throughputs and beyond the dynamic range of the wavefront sensor. In the proposed concept, a direct measurement of the wavefront is carried out, where a few segments of the wavefront are measured with Shack–Hartmann sensors (SHSs). In total about 1% of the wavefront is measured and used for the reconstruction of the entire wavefront, which makes the concept suitable for applications where low measurement times are needed. A simulation analysis and an experimental validation of the concept are carried out, and results show that a wavefront with a divergence of 62° can be reconstructed with a root-mean-square error of about 200 nm.

A test station setup devised to measure the emission characteristics and beam propagation parameters of a light detection and ranging (LiDAR) system is presented. The main blocks of the station to measure the accessible emission, wavelength peak and FWHM, pulse duration, pulse repetition rate, horizontal and vertical angular resolution, field of view, beam propagation factor M2, beam waist size, waist location, and divergence are described. The performance of this test station was demonstrated using a commercial spinning LiDAR, a Velodyne VLP-16, which successfully enables these measurements for a laser beam with a wavelength of 913 nm.

Published: November 2023

The Pound–Drever–Hall (PDH) cavity-locking scheme has found prevalent
uses in precision optical interferometry and laser frequency
stabilization. A form of frequency modulation spectroscopy, PDH enjoys
superior signal-to-noise recovery, large acquisition dynamic range,
wide servo bandwidth, and robust rejection of spurious effects.
However, residual amplitude modulation at the signal frequency, while
significantly suppressed, still presents an important concern for
further advancing the state-of-the-art performances. Here we present a
simplified and improved scheme for PDH using an acousto-optic
modulator to generate digital phase reference sidebands instead of the
traditionally used electro-optic modulator approach. We demonstrate
four key advantages: (1) the carrier and two modulation tones
are individually synthesized and easily reconfigured,
(2) robust and orthogonal control of the modulated optical
field is applied directly to the amplitude and phase quadratures,
(3) modulation synthesis, demodulation, and feedback are
implemented in a self-contained and easily reproducible electronic
unit, and (4) superior active and passive control of residual
amplitude modulation is achieved, especially when the carrier power is
vanishingly low. These distinct merits stimulate new ideas on how we
optimally enact PDH for a wide range of applications.
The effect of low-fidelity simulation training on breastfeeding knowledge, practice, and self-efficacy among young lactating mothers in Tanzania: A quasi-experimental study
Authors: Kaiza Rogers , Joho Angelina A. 
Published: November 2023

Background
Exclusive breastfeeding (EBF) is of paramount importance for the survival, growth, and development of neonates. Lack of EBF puts mothers and their babies at high risk of many complications. Mothers may end up having breast engorgement, cracked nipple, mastitis, breast pain, and backache. Babies may acquire postnatal HIV transmission, reduce weight, stunting, poor cognitive and motor development, and increase the risk of diarrhea disease and respiratory infection. Breastfeeding training has been provided immediately after a women’s birth. However, young mothers are still staggering with breastfeeding.

Research aim
We aim to assess the effect of low-fidelity simulation training on breastfeeding knowledge, practice, and self-efficacy among young lactating mothers and we will also assess the impact of simulation on infants’ weight in Tanzania.

Methods
The study will be a health facility-based quasi-experimental design. The study will have four phases: baseline survey, intervention, immediate assessment, and two-month end-line follow-up. The assessment will focus on participants’ breastfeeding knowledge, practice, and self-efficacy. Furthermore, infant weight will also be assessed during baseline and end-line. A total of 261 young lactating mothers who have first baby with their infants aged 0 to 2 months will be included, whereby 87 young lactating mothers will be in an interventional group and 174 will be in the control group. The intervention will have four packages: 1) group lecture education and interactive on the importance of breastfeeding 2) videos, 3) pictures, and 4) simulation in the umbrella LVPS using the wearable Lactation Simulation Model (LSM) and newborn manikins (Global Health Media and Laerdal baby). At the end of the study, all groups will be given education brochures which will be in the Swahili language for easy understanding. Data will be analyzed using SPSS version 23. An independent T-test and repeated measures ANOVA will be used in this study to compare the difference between the mean of the 2 groups.

Discussion
This study aims to generate evidence of the effect of simulation on improving breastfeeding knowledge, practice, and self-efficacy. We expect the study findings to inform the stakeholders and policymakers on formulating breastfeeding education and simulation training that will improve women’s breastfeeding knowledge, practice, and self-efficacy and improve infant health.
Comparison of different techniques for prehospital cervical spine immobilization: Biomechanical measurements with a wireless motion capture system

Published: November 2023

Background
Various rescue techniques are used for the prehospital transport of trauma patients. This study compares different techniques in terms of immobilization of the cervical spine and the rescue time.

Methods
A wireless motion capture system (Xsens Technologies, Enschede, The Netherlands) was used to record motion in three-dimensional space and the rescue time in a standardized environment. Immobilization was performed by applying different techniques through different teams of trained paramedics and physicians. All tests were performed on the set course, starting with the test person lying on the floor and ending with the test person lying on an ambulance cot ready to be loaded into an ambulance. Six different settings for rescue techniques were examined: rescue sheet with/without rigid cervical collar (P1S1, P1S0), vacuum mattress and scoop stretcher with/without rigid cervical collar (P2S1, P2S0), and long spinal board with/without rigid cervical collar (P3S1, P3S0). Four time intervals were defined: the time interval in which the rigid cervical collar is applied (T0), the time interval in which the test person is positioned on rescue sheet, vacuum mattress and scoop stretcher, or long spinal board (T1), the time interval in which the test person is carried to the ambulance cot (T2), and the time interval in which the ambulance cot is rolled to the ambulance (T3). An ANOVA was performed to compare the different techniques.

Results
During the simulated extrication procedures, a rigid cervical collar provided biomechanical stability at all angles with hardly any loss of time (mean angle ranges during T1: axial rotation P1S0 vs P1S1 p<0.0001, P2S0 vs P2S1 p<0.0001, P3S0 vs P3S1 p<0.0001; lateral bending P1S0 vs P1S1 p = 0.0263, P2S0 vs P2S1 p<0.0001, P3S0 vs P3S1 p<0.0001; flexion/extension P1S0 vs P1S1 p = 0.0023, P2S0 vs P2S1 p<0.0001). Of the three techniques examined, the scoop stretcher and vacuum mattress were best for reducing lateral bending in the frontal plane (mean angle ranges during T1: P2S1 vs P3S1 p = 0.0333; P2S0 vs P3S0 p = 0.0123) as well as flexion and extension in the sagittal plane (mean angle ranges during T2: P1S1 vs P2S1 p<0.0001; P1S0 vs P2S0 p<0.0001). On the other hand, the rescue sheet was clearly superior in terms of time (total duration P1S0 vs P2S0 p<0.001, P1S1 vs P2S1 p<0.001, P1S0 vs P3S0 p<0.001, P1S1 vs P3S1 p<0.001) but was always associated with significantly larger angular ranges of the cervical spine during the procedure. Therefore, the choice of technique depends on various factors such as the rescue time, the available personnel, as well as the severity of the suspected instability.
Fear of missing out and problematic smartphone use among Chinese college students: The roles of positive and negative metacognitions about smartphone use and optimism
Authors: Guan Jinliang , Ma Wangyan , Liu Chengzhen 
Published: November 2023

Background
Problematic smartphone use (PSU) has become a common phenomenon among college students. Fear of missing out (FoMO) is an important factor affecting PSU, but how FoMO affects PSU is not clear. Therefore, the mediating effect of positive and negative metacognitions about smartphone use (PMSU and NMSU) and the moderating effect of optimism are explored.

Methods
514 Chinese college students aged 17 to 25 from 6 Chinese universities were investigated with the Trait-State FoMO Scale, the Metacognitions about Smartphone Use Questionnaire, the Temperament Optimism Scale, and the Smartphone Addiction Scale for College Students. The data were analyzed with SPSS software.

Results
FoMO was positively associated with PSU, PMSU and NMSU mediated this association. Optimism moderated the relationship between FoMO and PSU, i.e., FoMO had a less prominent positive effect on PSU for college students with a high level of optimism.

Conclusions
There is a positive relationship which exists between FoMO and PSU among college students. In addition, PMSU and NMSU play mediating roles in FoMO and PSU, and optimism plays an moderating role in FoMO and PSU. These findings can help not only educators understand the predictors of PSU and develop interventions to effectively prevent PSU among college students but also college students reduce the level of PSU by improving their understanding of PMSU and NMSU and optimism level.
Public perceptions of physician-pharmaceutical industry relationships and trust in physicians
Authors: Saito Sayaka , Mukohara Kei , Shimomura Kazuhiro , Murotani Kenta 
Published: November 2023

Background
In Japan, as elsewhere, physicians meet with and receive gifts from pharmaceutical representatives (PRs). This study aimed to clarify the Japanese public perceptions of physicians’ relationships with PRs, examine the association between these perceptions and their trust in physicians, and compare the public’s and physicians’ awareness, acceptance, and perceptions of the influence of physician-PR relationships.

Methods
A cross-sectional, self-administered, anonymous, internet-panel survey was conducted involving 1,000 participants from the general public. The survey implementation was contracted to Cross Marketing Inc.

Results
The mean age of the 1000 participants was 44.8 years (standard deviation 18.3). Forty-eight percent were female. Many of our participants were unaware of certain physician-PR relationships. The public was more acceptable with physicians’ receiving stationery and/or medical textbooks and attending promotional drug seminars at their workplaces compared with receiving meals at restaurants. Many thought that physicians’ involvement in promotional activities influenced their prescribing habits and estimated that the majority of physicians received office stationery and meals from PRs. They were divided as to whether they would like to know about their physicians’ relationships with the industry. Factors associated with higher trust in physicians included participants being 65 years or older, having a primary care physician, being in better health, the belief that physicians’ involvement in promotional activities is acceptable, and their high estimate that physicians are not receiving gifts from PRs. Compared to the physicians, the public had lower awareness of and was more accepting of physicians’ involvement in promotional activities. Meanwhile, the public believed that physician-PR relationships influenced physicians’ prescribing habits more than the physicians themselves.

Conclusion
Our survey provided insights into Japanese public perceptions of physician-pharmaceutical industry relationships and their impact on trust in physicians. Physicians should be aware of these perceptions and carefully consider how to foster appropriate relationships with the industry.
Mendelian randomization reveals no correlations between herpesvirus infection and idiopathic pulmonary fibrosis
Authors: Yan Haihao , Zhu Chenghua , Jin Xiao , Feng Ganzhu 
Published: November 2023

Background
Previous studies have found that the persistence of herpesvirus significantly increases the risk of idiopathic pulmonary fibrosis (IPF), but it is unclear whether this effect is causal. We conducted a two-sample Mendelian randomization (MR) study to evaluate the causal relationship between three herpesvirus infections and IPF.

Methods
We used genome-wide association studies (GWAS) data from three independent datasets, including FinnGen cohort, Milieu Intérieur cohort, and 23andMe cohort, to screen for instrumental variables (IVs) of herpesvirus infection or herpesvirus-related immunoglobulin G (IgG) levels. Outcome dataset came from the largest meta-analysis of IPF susceptibility currently available.

Results
In the FinnGen cohort, genetically predicted Epstein-Barr virus (EBV) (OR = 1.105, 95%CI: 0.897–1.149, p = 0.815), cytomegalovirus (CMV) (OR = 1.073, 95%CI: 0.926–1.244, p = 0.302) and herpes simplex (HSV) infection (OR = 0.906, 95%CI: 0.753–1.097, p = 0.298) were not associated with the risk of IPF. In the Milieu Intérieur cohort, we found no correlations between herpesvirus-related IgG EBV nuclear antigen-1 (EBNA1) (OR = 0.968, 95%CI: 0.782–1.198, p = 0.764), EBV viral capsid antigen (VCA) (OR = 1.061, 95CI%: 0.811–1.387, p = 0.665), CMV (OR = 1.108, 95CI%: 0.944–1.314, p = 0.240), HSV-1 (OR = 1.154, 95%CI: 0.684–1.945, p = 0.592) and HSV-2 (OR = 0.915, 95%CI: 0.793–1.056, p = 0.225) and IPF risk. Moreover, in the 23andMe cohort, no evidence of associations between mononucleosis (OR = 1.042, 95%CI: 0.709–1.532, p = 0.832) and cold scores (OR = 0.906, 95%CI: 0.603–1.362, p = 0.635) and IPF were found. Sensitivity analysis confirmed the robustness of our results.

Conclusions
This study provides preliminary evidence that EBV, CMV, and HSV herpesviruses, and herpesviruses-related IgG levels, are not causally linked to IPF. Further MR analysis will be necessary when stronger instrument variables and GWAS with larger sample sizes become available.
Beyond Steiner's "Antigones": Myth Rewriting as Visitation of the Immemorial
Authors: Herzog Christophe 
Published: November 2023

This article focuses on the interrelations between myth, mythical character and rewriting. Faced with myth as an epistemological challenge, hermeneutics often is torn between two reductionist temptations: either to ontologize its object or to dissolve it into a kind of original nothingness. We will here first and mainly focus on George Steiner's Antigonesconsidered as a milestone in literary mythography because of its anti-reductionist approach characterized by attention to plurality and emphasis on the complexity inherent in myth. Secondly, and in a much more tentative manner, it will endeavor to propose a new conception of myth, supposedly able to satisfy the so far identified primordial demands it faces us with. We end up proposing a conception of rewriting as visitation and of myth as a face (visage) in Lévinas' sense, thereby ourselves revisiting notions like memory and transcendence. As memory of the immemorial, myth rewriting thus reveals itself paradoxically as a future-oriented, meaning making and hope inspiring task.
“Além”, o Poema Russo de Mário de Sá-Carneiro
Authors: Madeira Pedro , Nunes Ariadne 
Published: November 2023

Este artigo examina tanto o processo de criação de “Além” e “Bailado”, de Mário de Sá-Carneiro, incluídos em Céu em Fogo como um apêndice a “Asas”, como o desenvolvimento paralelo da narrativa ficcional da sua génese. Ambos estão amplamente documentados na correspondência entre Mário de Sá-Carneiro e Fernando Pessoa, em que aquele expõe uma poética própria, que tem como conceito central a ideia de transvio. Assumindo o carácter ostensivamente fragmentário desses textos, cujo sentido seria apenas sugerido e não coerentemente afirmado, Sá-Carneiro apresenta-os como uma tentativa de tematizar a distância entre a ideia abstracta do texto e a sua realização material. É esta poética o objecto de reflexão na primeira parte deste artigo.
Na segunda, deter-nos-emos na moldura ficcional criada em “Asas” para salvar e tornar legíveis “Além” e “Bailado”, depois das críticas de Pessoa, que os considerara ininteligíveis. Serão ambos apresentados, finalmente, como traduções de textos atribuídos ao poeta ficcional Petrus Ivanovich Zagoriansky, autor de um Poema perfeito que se teria desmaterializado no momento da sua conclusão. Estas traduções seriam tudo o que restava da sua obra. Os deslocamentos autorais (e linguísticos) implicados por esta moldura traduzirão em termos narrativos a mencionada ideia do transvio.
Literature, mobility, and the archive
Authors: Lopes Alexandra 
Published: November 2023

In 2019 Mexican-born Valeria Luiselli penned Lost Children Archive, which inaugurates her writing in English, and tells the interwoven stories of a blended family, as they take a road trip across America, and of the hardships of children travelling on foot to the US border.
The narrative is a poetic representation of lives in transit, and mobility informs it semantically and structurally: it is organized in four parts, each divided up in small sections, and includes manifold documents. In the narrative, the notion and the experience of the archive are of great importance, emerging out of multiple displacements. This being-in-transit conjures up a literal – it discusses the movement of people –, and figurative – it embraces multiple entanglements, renouncing completeness – translatedness.
While Lost Children Archive is a tour the force, and adds a layer of complexity her writing, Luiselli’s oeuvre, in Spanish and English, has always been characterized by an interpenetration of languages, texts, places, people – a close-knit interweaving of trajectories and memories. This results in an understanding of literature as assemblage, a ground in which to tentatively document existence. As such, it lends itself to an examination of the ways translation shapes the literary in a post-colonial, global(ized) world.
“Nós matamos o Cão Tinhoso” e Monólogos com a História: entre a literatura e o cinema
Authors: Flaiban Zanete Renata , Almeida Viviane , Macedo Lurdes 
Published: November 2023

O presente artigo busca analisar como o projeto de nação que se ambicionou para Moçambique aparece questionado em certas reescritas e memórias (por vezes conflitantes), remetendo-nos ao passado colonial e revolucionário. No decorrer da investigação, notamos que vários são os impulsos que movem as reescritas. As obras artísticas, de autores moçambicanos, que compõem o corpus deste estudo, refletem múltiplas motivações, por vezes sobrepostas, como a atualização, a homenagem, a contemporização, ou ainda a contraposição.
O conto fundacional “Nós matámos o Cão-Tinhoso” (2008[1964]), de Luís Bernardo Honwana, é retomado por Hélder Faife no conto breve “O Cão Tinhoso” (2013). Monólogos com a História (2019), do cineasta Sol de Carvalho, foi realizado sob a inspiração do conto “Um diálogo à beira duma sepultura” (2011), de Aldino Muianga. Desenvolvemos análises destes objetos de estudo em duplas e, depois, de modo transversal, a partir de conceitos que os atravessam. As figuras dos espectros e das ruínas, em diálogo com o mundo dos vivos, são recorrentes nas obras literárias e no filme que integram este artigo e constituem, para nós, imagens metafóricas que subsidiam a discussão aqui proposta.
Realizamos uma entrevista com o diretor cinematográfico Sol de Carvalho que nos permitiu confirmar a hipótese de que a(s) memória(s), a literatura e o cinema têm dialogado, na busca por possíveis interpretações e (re)leituras do passado, da História, no presente.
