Background
The SARS-CoV-2 pandemic presented a challenge for caregiving relatives in the home care setting. Caregivers can transmit SARS-CoV-2 to their relatives who are often at high risk for a severe course of COVID-19. Regular testing of asymptomatic caregivers for SARS-CoV-2 may reduce the risk of transmission. The optimal method and frequency of regular asymptomatic testing is unknown. We conducted a prospective, randomised trial to assess the feasibility, recruitment and acceptance of different testing frequencies. This serves to inform a future definitive randomised controlled trial.

Methods
We carried out a parallel three-armed feasibility trial, enrolling adult participants who provided home-based care for a relative at least twice a week. Participants were randomly assigned using sealed envelopes to either conduct saliva-based antigen self-testing at a frequency of once a week (group I), twice a week (group II), or every two days (group III). The participants completed questionnaires on a weekly basis. Main outcome measures were feasibility of recruitment, adherence to self-tests and distress caused by self-testing. We further collected data on the use of mouth-nose mask.

Results
From 25 March to 7 May 2021 we assessed 27 participants and randomised 26 in the study: 8 participants in group I, 8 in group II and 10 in group III. All participants completed the study. In group I 48/48 (100.0%; 95% CI 92.6% to 100.0%), in group II 93/96 (96.9%; 95% CI 91.2% to 98.9%) and in group III 209/210 (99.5%; 95% CI 97.4% to 99.9%) self-tests were carried out at home. Participants did not perceive regular self-testing as burdensome in any of the study arms. We did not observe any infection with SARS-CoV-2. During the study, mask adherence decreased from 35% to 19% in all groups.

Conclusion
Conducting such a study was feasible. The participants tolerated regular self-testing well, which was reflected in a high level of test adherence. However, regular self-testing may have led to decreased protective behaviour. To demonstrate that regular asymptomatic testing reduces infection transmission, a future definitive trial should be performed at a time of a high prevalence of SARS-CoV-2 and be implemented as a multicentre study.

Trial registration
The trial is registered with the German Clinical Trials Register, DRKS00026234.
Efectos del nombre de la marca sobre el comportamiento: el caso de la contrapublicidad del alcohol

Published: July 2024

La inversión mundial en publicidad de bebidas alcohólicas es elevada. En cambio, son escasas las campañas para reducir el consumo de alcohol entre los jóvenes. En este contexto, se ha decidido explorar el papel de distintos tipos de marcas, entendidas como señales, para prevenir el consumo de alcohol en anuncios de servicio público o contrapublicidad. Este estudio se ha enmarcardo en dos teorías: la teoría de la señalización y la teoría de la sensibilización a los incentivos. Su objetivo fue conocer los efectos de tres marcas diferentes sobre el comportamiento real en el consumo de alcohol entre jóvenes. Las marcas correspondieron a: un grupo de acción comunitaria, una cerveza ficticia y una agencia gubernamental. Se llevó a cabo un experimento en dos etapas: 1) 106 universitarios escucharon un anuncio radiofónico respaldado por cada marca, cuyo objetivo era prevenir el consumo de alcohol alertando sobre sus consecuencias negativas y; 2) se observó la decisión de consumo real de alcohol en las 24 horas siguientes a la audición del anuncio. En su conjunto, los resultados no confirmaron la teoría de la señalización de la contrapublicidad, aunque mostraron un comportamiento diferente según el sexo (los hombres beben más que las mujeres). Sin embargo se avaló la teoría de la sensibilización a los incentivos, ya que se hallaron diferencias en función de los hábitos de consumo. El artículo concluye con la discusión de los resultados y apunta como una futura línea de investigación el papel central de la creatividad en los mensajes de contrapublicidad.

Los trabajos aquí reunidos son resultado de un workshop organizado por el Grupo de Estudios sobre Estado, Espacio y Desarrollo del Instituto de Humanidades y Ciencias Sociales del Litoral. Los artículos problematizan sucesos contemporáneos como la crisis de hegemonía estadounidense y la transición actual de poder, la heterogeneidad en el ascenso del Sur Global, las características que adquieren las crecientes relaciones China-América Latina y la emergencia del Indo-Pacífico junto a la re-centralización económica en torno a la India. Indagar en estos procesos nos permite complejizar el abordaje del desarrollo como un proceso social y conflictivo en el sistema-mundo capitalista, en el cual intervienen dimensiones como la espacialidad del poder, el funcionamiento de las escalas, las trayectorias históricas, los Estados y las fuerzas sociales en disputa dentro de un escenario global jerárquico y desigual. En ese sentido, este número busca contribuir a una agenda de investigación en torno a las vinculaciones entre el desarrollo y las dinámicas geopolíticas y geoeconómicas.

AN ADDITIVE SUBDISTRIBUTION HAZARDS MODEL FOR COMPETING RISKS DATA
Authors: Molydah S Molydah S , Danardono Danardono 
Published: July 2024

Competing risk failure time data occur frequently in medical a number of methods have been proposed for the analysis of these data. The classic approach is to model all cause-specific hazards and then estimate the cumulative incidence curve based on these cause-specific hazards. Unfortunately, the cause-specific hazard function does not have a direct interpretation in terms of survival probabilities for the particular failure type. In this paper, we consider a more flexible model for the subdistribution. It is a combination of the additive model and the Cox model and allows one to perform a more detailed study of covariate effects. One advantage of this approach is that our regression modeling allows for non-proportional hazards. This leads to a new simple goodness-of-fit procedure for the proportional subdistribution hazards assumption that is very easy to use. We applied this method to melanoma data and estimated the cumulative death rate for those who died from melanoma after surgical removal of the tumor. It was found that two covariates had a time-varying effect and two other covariates had a constant effect in predicting the cumulative incidence curve in patients who died of melanoma following tumor removal surgery.

Abstract
Deep beams are crucial for construction projects due to their load-carrying capacity, shear resistance, and architectural adaptability. Ultra-high strength concrete and ultra-high-performance concrete (UHPC) are used in their production. Basalt fiber is used as an alternative due to its corrosion resistance, tensile strength, and thermal stability. This study investigates the behavior of UHPC deep beams reinforced with basalt fibers. Three sets of 11 specimens were constructed without transverse reinforcement and reinforced with either fibers or steel fibers. The study also analyzes the impact of parameters like shear strength capacity, crack development, and load-deflection behavior on UHPC deep beams. The study discovered that the inclusion of basalt fibers in UHPC deep beam can effectively postpone the onset of diagonal cracks. Incorporating basalt fiber at concentrations of 0.5, 0.75, and 1.0% led to respective increases of 48.17, 70.07, and 86.66% in the diagonal fracture force, as compared to the inclusion of steel fibers which resulted in increases of 18.24, 56.93, and 98.54% in diagonal fracture loads. The ideal ratio for enhancing the maximum shear capacity was found to be 0.75% of basalt. This specific percent resulted in the highest measured force out of the three percentages that were examined. The addition of basalt fibers at concentrations of 0.5, 0.75, and 1.0% resulted in respective improvements of 11.62, 30.08, and 28.69% in the ultimate shear capacities. During that period, steel fibers significantly enhanced the ultimate shear capacity, resulting in an increase of 19.83, 34.49, and 55.24% compared to specimens without fiber reinforcement. Regarding the second parameter of this investigation, a drop in the shear span ratio is linked to an augmentation in shear capacity and a reduction in mid-span deflection to varying extents for both the utilization of basalt and steel fibers.

Abstract
Different alternative hosts can reduce or even avoid pre-imaginal conditioning of parasitoids in mass production programs. Spodoptera cosmioides (Walker) (Lepidoptera: Noctuidae) may be an alternative host for mass rearing the parasitoid Palmistichus elaeisis Delvare & LaSalle (Hymenoptera: Eulophidae). The objective of this study was to evaluate the parasitism, emergence, egg-to-adult period, progeny size, sex ratio, and consumption of host tissue per individual of P. elaeisis produced using S. cosmioides pupae in the laboratory. Newly formed S. cosmioides pupae were weighed, individualized in glass tubes and each one was exposed to six newly emerged P. elaeisis females during 48 h. These pupae were transferred to plastic pots until the emergence of P. elaeisis adults. Palmistichus elaeisis parasitized and emerged from 100.0 % and 87.5 % of the S. cosmioides pupae, respectively. The egg-to-adult period of P. elaeisis was 24.28 ± 0.18 days, with 109 ± 2 individuals emerging per host pupae. Mass consumption of the host was 2.56 ± 0.01 mg per parasitoid emerged. This is the first report of P. elaeisis parasitizing and developing in S. cosmioides pupae. The ease of rearing S. cosmioides with an artificial diet, and the high parasitism, emergence, and progeny size of P. elaeisis support the suitability of this alternative host to mass-rearing this parasitoid.

Abstract
Spectral reconstruction, critical for understanding sample composition, is extensively applied in fields like remote sensing, geology, and medical imaging. However, existing spectral reconstruction methods require bulky equipment or complex electronic reconstruction algorithms, which limit the system’s performance and applications. This paper presents a novel flexible all-optical opto-intelligence spectrometer, termed OIS, using a diffractive neural network for high-precision spectral reconstruction, featuring low energy consumption and light-speed processing. Simulation experiments indicate that the OIS is able to achieve high-precision spectral reconstruction under spatially coherent and incoherent light sources without relying on any complex electronic algorithms, and integration with a simplified electrical calibration module can further improve the performance of OIS. To demonstrate the robustness of OIS, spectral reconstruction was also successfully conducted on real-world datasets. Our work provides a valuable reference for using diffractive neural networks in spectral interaction and perception, contributing to ongoing developments in photonic computing and machine learning.
