People make mistakes: Obtaining accurate ground truth from continuous annotations of subjective constructs
Authors: Booth Brandon M. , Narayanan Shrikanth S. 
Published: September 2024

AbstractAccurately representing changes in mental states over time is crucial for understanding their complex dynamics. However, there is little methodological research on the validity and reliability of human-produced continuous-time annotation of these states. We present a psychometric perspective on valid and reliable construct assessment, examine the robustness of interval-scale (e.g., values between zero and one) continuous-time annotation, and identify three major threats to validity and reliability in current approaches. We then propose a novel ground truth generation pipeline that combines emerging techniques for improving validity and robustness. We demonstrate its effectiveness in a case study involving crowd-sourced annotation of perceived violence in movies, where our pipeline achieves a .95 Spearman correlation in summarized ratings compared to a .15 baseline. These results suggest that highly accurate ground truth signals can be produced from continuous annotations using additional comparative annotation (e.g., a versus b) to correct structured errors, highlighting the need for a paradigm shift in robust construct measurement over time.

Constraints on the Gas-phase C/O Ratio of DR Tau's Outer Disk from CS, SO, and C2H Observations

Published: September 2024

Abstract
Millimeter wavelength observations of Class II protoplanetary disks often display strong emission from hydrocarbons and high CS/SO values, providing evidence that the gas-phase C/O ratio commonly exceeds 1 in their outer regions. We present new NOEMA observations of CS 5–4, SO 76–65 and 56–45, C2H N = 3–2, HCN 3–2, HCO+ 3–2, and H13CO+ 3–2 in the DR Tau protoplanetary disk at a resolution of ∼0.″4 (80 au). Estimates for the disk-averaged CS/SO ratio range from ∼0.4 to 0.5, the lowest value reported thus far for a T Tauri disk. At a projected separation of ∼180 au northeast of the star, the SO moment maps exhibit a clump that has no counterpart in the other lines, and the CS/SO value decreases to <0.2 at its location. Thermochemical models calculated with DALI indicate that DR Tau’s low CS/SO ratio and faint C2H emission can be explained by a gas-phase C/O ratio that is <1 at the disk radii traced by NOEMA. Comparisons of DR Tau’s SO emission to maps of extended structures traced by 13CO suggest that late infall may contribute to driving down the gas-phase C/O ratio of its disk.
Angular Momentum Loss during Stable Mass Transfer onto a Compact Object: The Effect of Mass Loss via Accretion Disk Winds
Authors: Gallegos-Garcia Monica , Jacquemin-Ide Jonatan , Kalogera Vicky 
Published: September 2024

Abstract
We use an analytic framework to calculate the evolution of binary orbits under a physically motivated model that accounts for angular momentum loss associated with winds from an accretion disk around the compact-objected accretor. Our prescription considers wind mass ejection from the surface of an accretion disk, accounting for a radial mass-loss dependence across the disk surface. We compare this to the standard prescription of angular momentum loss associated with isotropic mass loss from the vicinity of the accretor. The angular momentum loss from a disk wind is always larger. For mass ratios, q, between 2 and 10, angular momentum loss via a disk wind can be ≃3–40 times greater than the standard prescription. For the majority of mass ratios and disk properties, accounting for the disk wind can result in considerably smaller orbital separations compared to the standard formalism, the differences being ≃60% depending on how long the effect is integrated for. We conclude that it is important to consider the effects of angular momentum loss from a disk wind when evolving binary orbits.
The Challenge of Detecting Remote Spectroscopic Signatures from Radionuclides
Authors: Haqq-Misra Jacob , Kofman Vincent , Kopparapu Ravi K. 
Published: September 2024

Abstract
The characterization of exoplanetary atmospheres through transit spectra is becoming increasingly feasible, and technology for direct detection remains ongoing. The possibility of detecting spectral features could enable quantitative constraints on atmospheric composition or even serve as a potential biosignature, with the sensitivity of the instrument and observation time as key limiting factors. This paper discusses the possibility that future remote observations could detect the presence of radioactive elements in the atmospheres of exoplanets. Such radionuclides could arise from cosmogenic or geologic sources, as well as from industrial sources, all of which occur on Earth. The detection of radionuclides in an exoplanetary atmosphere could reveal important properties about the planet’s geology or space environment and potentially could serve as a technosignature. However, many radionuclides, including those from industrial sources, attach to aerosol or other particles that cannot be remotely characterized. Limited experimental and theoretical spectral data exist for long-lived radionuclides, but the sensitivity required to detect the spectral features of some known radionuclides would be at least several orders of magnitude greater than required to detect the spectral features of molecular oxygen. Present-day remote spectroscopic observing mission concepts at ultraviolet to mid-infrared wavelengths are not sensitive to discern the presence of radionuclides in exoplanetary atmospheres. Interplanetary fly-by or probe missions may be more likely to provide such data in the future.
The Independence of Magnetic Turbulent Power Spectra to the Presence of Switchbacks in the Inner Heliosphere
Authors: Tatum Peter D. , Malaspina David M. , Chasapis Alexandros , Short Benjamin 
Published: September 2024

Abstract
An outstanding gap in our knowledge of the solar wind is the relationship between switchbacks and solar wind turbulence. Switchbacks are large fluctuations, even reversals, of the background magnetic field embedded in the solar wind flow. It has been proposed that switchbacks may form as a product of turbulence and decay via coupling with the turbulent cascade. In this work, we examine how properties of solar wind magnetic field turbulence vary in the presence or absence of switchbacks. Specifically, we use in situ particle and fields measurements from Parker Solar Probe to measure magnetic field turbulent wave power, separately in the inertial and kinetic ranges, as a function of switchback magnetic deflection angle. We demonstrate that the angle between the background magnetic field and the solar wind velocity in the spacecraft frame (θ

vB
) strongly determines whether Parker Solar Probe samples wave power parallel or perpendicular to the background magnetic field. Further, we show that θ

vB
is strongly modulated by the switchback magnetic deflection angle. In this analysis, we demonstrate that switchback deflection angle does not correspond to any significant increase in wave power in either the inertial range or at kinetic scales. This result implies that switchbacks do not strongly couple to the turbulent cascade in the inertial or kinetic ranges via turbulent wave–particle interactions. Therefore, we do not expect switchbacks to contribute significantly to solar wind heating through this type of energy conversion pathway although contributions via other mechanisms, such as magnetic reconnection, may still be significant.

Abstract
Neutral sodium (Na i) is an alkali metal with a favorable absorption cross section such that tenuous gases are easily illuminated at select transiting exoplanet systems. We examine both the time-averaged and time-series alkali spectral flux individually, over 4 nights at a hot Saturn system on a ∼2.8 day orbit about a Sun-like star WASP-49 A. Very Large Telescope/ESPRESSO observations are analyzed, providing new constraints. We recover the previously confirmed residual sodium flux uniquely when averaged, whereas night-to-night Na i varies by more than an order of magnitude. On HARPS/3.6 m Epoch II, we report a Doppler redshift at v
Γ,NaD = + 9.7 ± 1.6 km s−1 with respect to the planet’s rest frame. Upon examining the lightcurves, we confirm night-to-night variability, on the order of ∼1%–4% in NaD, rarely coinciding with exoplanet transit, not readily explained by stellar activity, starspots, tellurics, or the interstellar medium. Coincident with the ∼+10 km s−1 Doppler redshift, we detect a transient sodium absorption event dF
NaD/F
⋆ = 3.6% ± 1% at a relative difference of ΔF
NaD(t) ∼ 4.4% ± 1%, lasting Δt
NaD ≳ 40 minutes. Since exoplanetary alkali signatures are blueshifted due to the natural vector of radiation pressure, estimated here at roughly ∼−5.7 km s−1, the radial velocity is rather at +15.4 km s−1, far larger than any known exoplanet system. Given that the redshift magnitude v
Γ is in between the Roche limit and dynamically stable satellite orbits, the transient sodium may be a putative indication of a natural satellite orbiting WASP-49 A b.

Bancos de desenvolvimento como braço de política pública para transição verde sustentável
Authors: Fernanda Fernanda Feil , Feijo Carmem 
Published: September 2024

O processo de adaptação e mitigação à mudança climática exige uma rápida transição verde sustentável. A principal responsabilidade por este processo cabe aos Estados que são legitimados e têm um amplo espectro de instrumentos à sua disposição, tais quais suas instituições e políticas econômicas. Para tanto, tanto, a intencionalidade da promoção do desenvolvimento sustentável necessita do alinhamento das políticas do Estado, suas instituições e, como reflexo, as políticas adotadas – fiscal, monetárias, cambial e industrial, junto com a política de crédito público, devem juntas, garantir a longevidade e sustentabilidade do processo. Bancos de desenvolvimento são essenciais para o processo, mas sua eficácia somente será garantida se houver concatenação das políticas macroeconômicas convencionais atuando em harmonia com os demais instrumentos disponíveis pelo Estado. Para tanto, necessitam não apenas incorporar a sustentabilidade em sua missão, mas especialmente, necessitam de legitimidade para liderarem essa transformação do sistema financeiro e das relações de produção. Partimos da hipótese de que a existência de um sistema financeiro eficiente é condição necessária, mas não suficiente, para a sustentação do processo de desenvolvimento sustentável e da garantia do nível de investimento de forma a assegurar que ocorra mudança estrutural da economia. A funcionalidade do sistema financeiro deve estar voltada para esse novo desafio.
Cold Sprayed Copper-Diamond Composites for Thermal Management of Semiconductor Packages
Authors: Li Wenhao (Eric) , Eid Feras , Tomita Yoshihiro 
Published: September 2024

Thermal management is key to enabling increasingly powerful chips and heterogeneous integrated 2.5D/3-D systems. Composite materials with high thermal conductivities that can be placed at different levels of proximity to the die provide new solutions for heat dissipation. Here we report the fabrication of thick copper-diamond composite films using cold spray, which is a high-throughput, low-thermal-budget deposition technology. In cold spray, feedstock micro powder is accelerated in a specially designed nozzle by a heated pressurized gas and adheres to the substrate upon high-speed impingement. This process achieves higher deposition rates than other methods used in semiconductor manufacturing (such as electroplating). It also produces films that are denser and much less porous than ones produced by conventional thermal spray techniques. In this work, we first use process and thermal simulations to determine the requirements of the micro diamond powder feedstock, including the diamond core size, metal-clad thickness, core-clad interfacial resistance, and volume fraction to enable the cold spray of copper-diamond composites with thermal conductivities that are higher than copper. Subsequently, we perform a systematic characterization of the diamond powders from several suppliers, including the purity, metal oxygen content, particle morphology, and metal-clad adhesion. This characterization reveals the challenges of meeting all the specs using currently available diamond powders. Finally, we cold spray copper-diamond composite films on a variety of substrates with tunable thicknesses between 100 mm and 2 mm, achieving a thermal conductivity that is approximately 10% higher than cold-sprayed pure copper. Further improvement of the thermal properties relies on continued innovation in powder surface modification and powder storage/shipping methods.
Coping strategies adopted by caregivers of children with autism in the Limpopo Province, South Africa
Authors: Sumbane Gsakani O. 
Published: September 2024

Background: Emotion- and problem-focused coping strategies are frequently employed by caregivers of autistic children to increase their general well-being and resilience to the stress of raising the child. Although these strategies cannot directly address the situation, it is useful for handling stressful situations that cannot change.Objectives: The study seeks to explore and understand the emotion- and problem-focused strategies that caregivers use to cope with the challenges of raising a child with autism.Method: This was a qualitative, exploratory and descriptive research study. Twenty-eight caregivers were purposive-convenient sampled from the public special schools where their autism spectrum disorder (ASD) children are schooling. Semi-structured interviews were used to gather data, which were then transcribed and subjected to thematic analysis.Results: Positive emotion-focused strategies include positive reappraisal, reframing and acceptance. Negative emotion-focused strategies include denial, emotional release, cognitive distortion, self-isolation, overprotection, negative self-talk, punishment and religion. Problem-focused coping strategies include active and adaptive coping, peer group, professional support and social support.Conclusion: The coping methods that have been identified can be integrated into intervention programmes and serve as a guide for specialised institutions that offer more extensive knowledge and assistance to families who are caring for children with ASD.Contribution: The study contributes to understanding the emotion- and problem-focused strategies adopted by rural caregivers in managing their emotions, interpretation of the situation and adjusting to the demands of raising an autistic child.

Authors: Van Tonder Grethe , Du Preez Ronel , Pentz Christian D. 
Published: September 2024

Purpose: This study addresses the qualitative research phase of a mixed methods study conducted to investigate patient acceptance of an app-based telemedicine service for primary care aimed at South African public health care sector patients.Design/methodology/approach: Qualitative data were collected by means of semi-structured individual interviews with patients who had exposure to an existing app-based primary care telemedicine service in South Africa named Kena Health. Thematic analysis of the qualitative data using ATLAS.ti software was conducted to identify the relevant antecedents of telemedicine service acceptance in the study’s context.Findings/results: Eight antecedents of app-based primary care telemedicine service acceptance among South African patients (who are predominantly reliant on public health care sector services to receive medical care) were identified, namely, perceived compatibility, perceived ease of use, relative advantage, price value, trust, innovativeness, privacy perception and care perception.Practical implications: To date, prior literature has not yet identified the specific antecedents that would apply to the acceptance of an app-based telemedicine service for primary care among South African individuals who are predominantly reliant on the country’s public health care system to receive medical care.Originality/value: Our study contributes to the literature by identifying which existing factors of technology acceptance apply to primary care telemedicine service acceptance, predominantly in the South African public health care sector context. Furthermore, additional antecedents of telemedicine service acceptance that have not been included in technology acceptance theory until present, that is, (positive) privacy perception and care perception are identified.
Gender Differences in the Relationship between Forearm Length and Height across Different Age Groups: A Correlation and Regression Analysis
Authors: Joshi Aparnamilind , Thorat Shweta Shankarrao 
Published: September 2024

Abstract

Introduction:
Forearm length (FrL) and height (Ht) are important anthropometric measurements used in clinical practice and research. This study aimed to investigate the correlation and regression between FrL and Ht in males and females across different age groups.

Materials and Methods:
Participants aged 18 to under 23 years were recruited, and FrL and Ht were measured using standardised techniques. Pearson’s correlation coefficient and regression analysis were used to analyse the data.

Results:
The correlation analysis revealed a moderate-to-strong positive correlation between FrL and Ht in males across all age groups, with correlation coefficients ranging from 0.318 to 0.866. In females, the correlation was weaker, ranging from 0.123 to 0.561. Regression equations were derived to estimate FrL from Ht, showing that Ht explains a larger proportion of the variability in FrL in males compared to females. These findings suggest that FrL can be used as a predictor of Ht, particularly in males, but caution is advised when applying this relationship to females. These results have implications for growth assessment and nutritional status evaluation in clinical practice, especially in populations, where direct measurement of Ht may be challenging.

Conclusion:
The study provides insights into the relationship between FrL and Ht, with implications for Ht estimation and growth assessment in clinical practice. Further research is needed to validate these findings in larger populations.
