Digital technologies: tensions in privacy and data
Authors: Quach Sara , Thaichon Park , Martin Kelly D. , Weaven Scott , Palmatier Robert W. 
Published: March 2022

AbstractDriven by data proliferation, digital technologies have transformed the marketing landscape. In parallel, significant privacy concerns have shaken consumer–firm relationships, prompting changes in both regulatory interventions and people’s own privacy-protective behaviors. With a comprehensive analysis of digital technologies and data strategy informed by structuration theory and privacy literature, the authors consider privacy tensions as the product of firm–consumer interactions, facilitated by digital technologies. This perspective in turn implies distinct consumer, regulatory, and firm responses related to data protection. By consolidating various perspectives, the authors propose three tenets and seven propositions, supported by interview insights from senior managers and consumer informants, that create a foundation for understanding the digital technology implications for firm performance in contexts marked by growing privacy worries and legal ramifications. On the basis of this conceptual framework, they also propose a data strategy typology across two main strategic functions of digital technologies: data monetization and data sharing. The result is four distinct types of firms, which engage in disparate behaviors in the broader ecosystem pertaining to privacy issues. This article also provides directions for research, according to a synthesis of findings from both academic and practical perspectives.
Customer-oriented salespeople’s value creation and claiming in price negotiations
Authors: Kassemeier Roland , Alavi Sascha , Habel Johannes , Schmitz Christian 
Published: March 2022

AbstractAlthough customer orientation is widely endorsed as a crucial salesperson characteristic, little is known about its effect in price negotiations with customers. This study rectifies this omission and argues for its ambiguous effects. While customer-oriented salespeople create value for customers that enables them to reduce price concessions, they may overly focus on customers’ needs and, in doing so, hesitate to defend against such requests. Results of two quantitative studies and one preliminary qualitative study reveal that customer-oriented salespeople do not unconditionally benefit from their created value in price negotiations with customers. That is, salespeople effectively leverage their created value to negotiate prices with customers only if their sales managers instill confidence that high prices are justified. Furthermore, we find that profit-related incentives reduce undesired consequences of salespeople’s customer orientation in price negotiations.

Published: March 2022

Abstract

Introduction
There is very little literature on referred pain syndromes with orgasm. Referred foot pain with orgasm is rare and evidence based diagnosis and management is not defined. Dysorgasmia is a pain condition that can severely affect sexual health and quality of life.

Aim
To add to the understanding and scant literature on referred orgasmic pain with pelvic floor and myofascial etiology.

Methods
A 34-year-old cis-female presented to a Physiotherapist, Sexual Medicine Physician, and Sex Therapist with a rare case of new insidious onset right foot pain with orgasm.

Results
Femoral nerve entrapment was diagnosed at the level of the inguinal ligament, referring pain to the right terminal sensory branch of the saphenous nerve along the medial aspect of the foot. Physiotherapy management resolved the patient's pain, while medical assessment was important to rule out numerous potential pathologies and to facilitate multidisciplinary management. Psychological therapy via sex therapy was integral in the highly successful and improved sexual outcome for this patient and her husband.

Conclusion
This case report details the successful multi-disciplinary assessment and management of a rare dysorgasmia and the importance of addressing sexual sequelae to add to the small amount of literature on difficult referred pain syndromes during sexual arousal and orgasm.

AbstractFor over a decade, the Super Dual Auroral Radar Network and the Active Magnetosphere and Planetary Electrodynamics Response Experiment have been measuring ionospheric convection and field‐aligned currents in the high‐latitude regions, respectively. Using both, high‐latitude maps of the magnetosphere‐ionosphere energy transfer rate (the Poynting flux) have been generated with a time resolution of 2 min between 2010 and 2017. These data driven Poynting flux (PF) patterns are used in this study to perform a superposed epoch analysis of the northern hemisphere ionospheric response to transitions of the interplanetary magnetic field Bz component, upwards of 60° geomagnetic latitude. We discuss the difference in the distribution of PF between the magnetosphere‐ionosphere Dungey cycle “switching on” and “switching off” to solar wind driving, revealing that they are not symmetric temporally or spatially.

Published: March 2022

AbstractIn this work, photon‐to‐photon polarization modulation is experimentally demonstrated using a Mxene material, Ti2C thin film as a modulator. S‐band signal (1500 nm) polarization state is modulated by a control pump (1400 nm) in the Ti2C thin film based on the thermo‐optic effect. A total of 34.67˚ of polarization rotation is achieved with the variation of pump power from 0 to 223 mW. From the regression analysis, the system is operated in highly linear condition, with R2 value of 0.991 and an efficiency of 0.1589˚/mW. Throughout the polarization rotational range, the variation of ellipticity is less than 5˚ while the variation of output power is less than 3.5 dB.

Published: March 2022

AbstractFor the safety of humans and animals in the vicinity of single‐phase earth faults in ungrounded AC systems, the development of methods for monitoring the condition of insulation and protection against electric shocks is an important issue. This paper presents a method for determining insulation parameters in ungrounded AC systems, which provides: (1) Satisfactory accuracy; (2) easy measurements of the voltage modules magnitude; (3) safety when working in electrical installations. The proposed method is based on measuring the zero‐sequence voltage module and phase‐to‐earth voltage module, as well as the angle of phase‐to‐earth voltage vector and zero‐sequence voltage vector before and after connection of additional conductivity between a phase and the earth. In addition, the obtained insulation parameters enable the zero‐sequence current to be decomposed into an active and reactive component, thus ensuring accurate compensation of capacitive currents. By monitoring the state of the active conductivity value, the value of the single‐phase earth‐fault current can be determined at an early stage and the relay protection can thus be correctly set. Consequently, by knowing the insulation condition parameters, the single‐phase earth‐fault currents can be monitored and reduced more effectively, and thus the step voltage, which determines the degree of safety.

AbstractThe agglomeration causes a significant challenge to nanodielectrics. Identification of agglomerates in scanning electron microscopy (SEM) images is an important step of solving this issue. Motivated by the fast development of image recognition in computer vision, we propose a new approach for agglomerates identification in SEM images of nanodielectrics by semantic segmentation, which is more efficient and accurate than traditional methods. Three models based on convolutional neural networks are investigated in this work, namely pixel blocks classification network, full convolutional segmentation network employed with data augmentation and unsupervised self‐encoding network. All three networks can preliminarily identify agglomerates of spherical silica‐based blend polyethylene nanocomposites. The mean intersection over union (mIoU) of pixel blocks classification network is 0.843 and it takes 25 s to process an image. Full convolutional segmentation network only needs 0.059 s to process a sample, with a mIoU of 0.777. Unsupervised self‐encoding network can reach a mIoU of 0.747 at a speed of 5.806 s. According to the amount of data sets, and requirements for different speed and accuracy, three kinds of networks can be flexibly selected.

Context. There is ample evidence that dust is already present in abundance at high redshift. However, given the faintness of distant galaxies in the optical and the near-infrared, the data are limited and the understanding of how the dust affects the emerging radiation of galaxies at very high redshift is still limited.
Aims. Using the ALMA Large Program to INvestigate [C II] at Early times (ALPINE), our objective is to quantify the dust attenuation properties in galaxies at z = 4.4–5.5, particularly with regard to the shape of their attenuation curve.
Methods. Using the CIGALE spectral energy distribution (SED) code, we modeled the stellar populations and their interactions with the dust to measure some of the physical properties of the ALPINE sample. We selected a subsample of 23 main-sequence galaxies requiring a detection in at least six bands in the rest-frame UV and optical, as well as in the dust continuum around 158 μm or the [C II] fine-structure line. The inclusion of this line is important for improving the constraints on the physical properties, while achieving a reasonably low uncertainty on the slope of the attenuation curves.
Results. We find that the attenuation curves span a broad range of properties – from curves that are much steeper than the SMC extinction curve to those that are shallower than the starburst attenuation curve. The shape of the attenuation curves strongly depends on the V-band attenuation. Galaxies with the lowest attenuation also present the steepest curves. The steepness of such curves probably results from the combination of the intrinsic physical properties of the dust, the relative distribution of stars and dust in the interstellar medium, and the differential reddening, with an important fraction of the dust concentrated in star-forming regions. The broad range of attenuation curves found at z ∼ 5 shows that no single attenuation curve is appropriate for main-sequence galaxies. When SED modeling is not feasible, assuming a fixed curve can lead to large errors, for instance, in the interpretation and application of the IRX-β diagram.
Conclusions. Considerable caution should be exercised when correcting high redshift galaxies for the presence of dust using the UV slope β as it can affect the estimation of both star formation rates and stellar mass even at low V-band attenuation due to the steepness of the attenuation curve. However, when SED modeling can be used, the impact of the choice of the attenuation curve on the star formation rate and the stellar mass is limited.

Context.N2is rarely found in comets, or when it is present, it is found only in small quantities despite its abundance on the surfaces of different outer Solar System objects. A few comets presented N2+emission lines in their optical spectra. One of them, C/2016 R2, showed an unusually high abundance of this species in 2018, with dozens of bright N2+emission lines. A robust model of the N2+fluorescence in comets would permit us to perform a detailed quantitative analysis of this species and enlarge our comprehension of the surprisingly wide range of N2abundances in comets.Aims.The goal of this work is to provide the necessary tools to interpret N2+spectra. Computing production rates for a cometary species necessitates a good knowledge of the number of molecules located along the line of sight of the spectrometer. This in turn requires a good modeling of the emission spectrum with detailed fluorescence efficiencies for the different bands.Methods.We developed a model based on available laboratory data and new theoretical results relative to the N2+to compute the emission spectrum of this species observed in 8.2m Very Large Telescope high-resolution spectra of comet C/2016 R2. Because of some significant differences between spectra obtained on the nucleus and at a cometocentric distance of about 6000 km, it became apparent that a classic fluorescence equilibrium spectrum could not be used. A synthetic spectrum based on a Monte Carlo method and producing spectra at different times from an initial relative population was developed and compared to our observational data.Results.Our modeling of the cometary N2+emission spectrum satisfactorily fits our observed spectra of comet C/2016 R2, leading to the first modeling at high resolution. Different fluorescence efficiency factors are computed.

Published: March 2022

Significance
We demonstrate that a tsunami in the late 14th century CE destroyed coastal sites along a critical part of the maritime Silk Road and set in motion profound changes in the political economy of Southeast Asia. Our results provide a precise chronology of settlement and trade along a historically strategic section of the Sumatran coast and are robust physical evidence for the rise of the Aceh Sultanate. Tragically, coastal areas impacted by the late 14th century tsunami were devastated by the 2004 Indian Ocean tsunami. This makes our findings relevant to debates about hazard mitigation and risk reduction. This example shows that archaeological, historical, and geological data are relevant in discussions about the long-term sustainability of communities exposed to geological hazards.

Published: March 2022

Abstract

Background
Frailty can be operationalised using the deficit accumulation approach, which considers health deficits across multiple domains. We aimed to develop, validate and compare three different frailty indices (FI) constructed from self-reported health measures (FI-Self Report), blood-based biomarkers (FI-Blood) and examination-based assessments (FI-Examination).

Methods
Up to 30,027 participants aged 45–85 years from the baseline (2011–2015) comprehensive cohort of the Canadian Longitudinal Study on Aging were included in the analyses. Following standard criteria, three FIs were created: a 48-item FI-Self Report, a 23-item FI-Blood and a 47-item FI-Examination. In addition a 118-item FI-Combined was constructed. Mortality status was ascertained in July 2019.

Results
FI-Blood and FI-Examination demonstrated broader distributions than FI-Self Report. FI-Self Report and FI-Blood scores were higher in females, whereas FI-Examination scores were higher in males. All FI scores increased nonlinearly with age and were highest at lower education levels. In sex and age-adjusted models, a 0.01 increase in FI score was associated with a 1.08 [95% confidence interval (CI): 1.07,1.10], 1.05 (1.04,1.06), 1.07 (1.05,1.08) and a 1.13 (1.11,1.16) increased odds of mortality for FI-Self Report, FI-Blood, FI-Examination and FI-Combined, respectively. Inclusion of the three distinct FI types in a single model yielded the best prognostic accuracy and model fit, even compared to the FI-Combined, with all FIs remaining independently associated with mortality.

Conclusion
Characteristics of all FIs were largely consistent with previously established FIs. To adequately capture frailty levels and to improve our understanding of the heterogeneity of ageing, FIs should consider multiple types of deficits including self-reported, blood and examination-based measures.

Abstract
Limited data are available about the potential health effects of infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on pregnant women and their developing offspring. We established the International Registry of Coronavirus Exposure in Pregnancy (IRCEP) to provide data on the risk of major adverse obstetric and neonatal outcomes among women with varying degrees of severity and timing of coronavirus disease 2019 (COVID-19) during pregnancy. We describe here the cohort and share the lessons learned. The IRCEP enrolls women tested for SARS-CoV-2 or with a clinical diagnosis of COVID-19 during pregnancy and obtains information using an online data collection system. By March 2021, 17,532 participants from 77 countries had enrolled; 54% enrolled during pregnancy and 46% afterward. Among women with symptomatic COVID-19 with a positive SARS-CoV-2 test (n = 4,934), symptoms were mild in 41%, moderate in 52%, and severe in 7%; 7.7% were hospitalized for COVID-19 and 1.7% were admitted to an intensive care unit. The biggest challenges were retention of participants enrolled during pregnancy and the potential bias introduced when participants enroll after pregnancy outcomes are known. Multiple biases need to be considered and addressed when estimating and interpreting the effects of COVID-19 in pregnancy in these types of cohorts.

Abstract
There is a growing interest in using black soldier fly larvae (BSFL) due to its supposed sustainability and nutritional qualities. Because little research has been conducted to evaluate the use of BSFL in cats, our objective was to determine the palatability and apparent total tract macronutrient digestibility (ATTD) of BSFL-containing canned diets and the fecal characteristics of healthy adult cats consuming them. First, three palatability tests were conducted to compare the following diets: 1) diet with poultry byproduct meal (PBPM) and chicken serving as the primary protein sources (control) vs. diet with BSFL meal replacing PBPM (BSFL meal); 2) control vs. diet with whole BSFL replacing some PBPM and poultry fat (BSFL whole); and 3) control vs. diet with BSFL oil replacing poultry fat (BSFL oil). All diets were formulated to meet Association of American Feed Control Officials nutrient profiles for adult cats and were produced using a still retort. A paired t-test was conducted to analyze data from each palatability test, with a higher (P &lt; 0.05) consumption ratio being observed for BSFL meal (1.93:1), BSFL whole (2.03:1), and BSFL oil (1.57:1). Second, 32 adult cats (20 females and 12 males; BW: 4.19 ± 0.55 kg; age: 3.3 ± 0.38 yr) were used in a completely randomized design study composed of a 21-d baseline period and a 70-d experimental period. Cats consumed the control diet during the baseline and were then allotted to one of four experimental diets (n = 8 per group): 1) control, 2) BSFL meal, 3) whole BSFL, and 4) BSFL oil. Fecal samples were collected after baseline and experimental periods for ATTD and fecal characteristic analysis. Fecal output was higher (P &lt; 0.05) and fecal dry matter percentage was lower (P &lt; 0.05) in cats fed BSFL meal than those fed BSFL oil. Organic matter, crude protein (CP), and energy ATTD were lower (P &lt; 0.05) in cats fed BSFL meal than those fed BSFL oil or control. CP and energy ATTD were lower (P &lt; 0.05) in cats fed BSFL whole than those fed BSFL oil. A few serum metabolites were affected by diet (P &lt; 0.05) but remained within reference ranges. Hematology was not affected by diet (P &gt; 0.05). Overall, our results suggest that BSFL-containing diets are palatable and do not negatively affect fecal characteristics or serum chemistry but may have slightly lower nutrient digestibilities in adult cats.
