The kind of silence: managing a reputation for voluntary disclosure in financial markets
Authors: Gietzmann Miles B. , Ostaszewski Adam J. 
Published: October 2023

AbstractWe create a continuous-time setting in which to investigate how the management of a firm controls a dynamic choice between two generic voluntary disclosure decision rules (strategies) in the period between two consecutive mandatory disclosure dates: one with full and transparent disclosure termed candid, the other, termed sparing, under which values only above a dynamic threshold are disclosed. We show how parameters of the model such as news intensity, pay-for-performance and time-to-mandatory-disclosure determine the optimal choice of candid versus sparing strategies and the optimal times for management to switch between the two. The model presented develops a number of insights, based on a very simple ordinary differential equation characterizing equilibrium in a piecewise-deterministic model, derivable from the background Black–Scholes model and Poisson arrival of signals of firm value. It is shown that in equilibrium when news intensity is low a firm may employ a candid disclosure strategy throughout, but will otherwise switch (alternate) between periods of being candid and periods of being sparing with the truth (or the other way about). Significantly, with constant pay-for-performance parameters, at most one switching can occur.

Published: October 2023

AbstractThere is growing concern surrounding the pervasive impacts of microplastic pollution, but despite increasing interest in this area there remains limited understanding of its disruption to biological communities and the ecosystem services they provide. One such service is the breakdown of leaf litter in freshwaters by invertebrate shredders, such as Gammarus spp., that directly and indirectly provides resources for many other species. This study investigates the effect of microplastic exposure on leaf consumption by two Gammarus species in Ireland, the native Gammarus duebeni celticus, and the invasive Gammarus pulex. Individuals were exposed to 40–48 μm polyethylene particles for 24 h at a range of concentrations (20–200,000 MP/L), with the amount of leaf consumption in that time frame recorded. Microplastics did not affect the feeding rate of either species at environmentally relevant concentrations, indicating that ecosystem services currently provided by our study species are sustainable. However, at higher microplastic concentrations the feeding rate of G. d. celticus was significantly reduced, whereas G. pulex remained unaffected, drawing attention to species-specific and native-invader differences in microplastic impacts. The results of our study further contribute to the observed pattern that invasive species, including various amphipod species, often display a higher tolerance to environmental stressors compared to their native counterparts. This research highlights the need for mitigation of ongoing and increasing microplastic pollution that could differentially influence key ecosystem services and functions.

Abstract
Purpose
The combination of trastuzumab and pertuzumab (HP) as part of a taxane-based regimen has shown benefit in the adjuvant and metastatic HER2 + breast cancer setting. In the CLEOPATRA trial, pruritus was reported in 11-17.6% of patients. The clinical phenotype and potential treatment strategies for this event have not been reported.

Methods
A retrospective review of 2583 patients receiving trastuzumab and pertuzumab for the treatment of HER2 + breast cancer from 11/23/2011 to 6/21/2021 was performed at Memorial Sloan Kettering Cancer Center (MSKCC). Patient demographics, pruritus characteristics, and treatments as documented in the electronic medical record (EMR) were included in this analysis.

Results
Of 2583 pts treated with HP, 122 (4.72%) with pruritus were identified. On average, patients experienced pruritus 319.0 days (8-3171) after initiation of HP. The upper extremities (67.4%), back (29.3%), lower extremities (17.4%), and shoulders (14.1%) were the most commonly affected regions. Grade 1/2 pruritus (97.6%) occurred in most cases. Patients responded primarily to treatment with topical steroids (52.2%), antihistamines (29.9%), emollients (20.9%), and gabapentinoids (16.4%). Of those with pruritus, 4 patients (3.3%) required treatment interruption or discontinuation.

Conclusions
Pruritus is uncommon in patients on trastuzumab and pertuzumab, generally a chronic condition, with gabapentinoids or antihistamines representing effective therapies.
Early Initiation of SGLT2 Inhibitors in Acute Heart Failure: a Focus on Diuresis and Renal Protection
Authors: Hammer Andreas , Niessner Alexander , Sulzgruber Patrick 
Published: October 2023

Abstract
Purpose
Acute heart failure (AHF) represents a critical and life-threatening condition characterized by the sudden onset or exacerbation of symptoms, such as dyspnea and fluid retention, due to impaired cardiac function. Despite advances in the treatment of chronic heart failure (HF), the management of AHF remains challenging, with limited therapeutic options available. Sodium-glucose cotransporter 2 (SGLT2) inhibitors have emerged as a promising drug class in AHF management.

Methods/Results
The objective of this article was to conduct a comprehensive review of the existing literature in the domain of SGLT2 inhibitors and their relevance in the context of AHF.

Conclusion
The existing evidence underscores the importance of SGLT2 inhibitors in enhancing decongestive therapy for AHF patients. Early initiation appears both practical and beneficial, leading to improved and sustained decongestion, a reduction in heart failure–related events, enhanced quality of life, and decreased mortality rates, all while maintaining a favorable safety profile. Consequently, it should be considered to initiate SGLT2 inhibitor treatment as early and as safely as possible to facilitate effective decongestion. However, careful patient selection and monitoring are essential when considering the use of these drugs in the management of AHF.
Impact of artificial topological changes on flow and transport through fractured media due to mesh resolution

Published: October 2023

AbstractWe performed a set of numerical simulations to characterize the interplay of fracture network topology, upscaling, and mesh refinement on flow and transport properties in fractured porous media. We generated a set of generic three-dimensional discrete fracture networks at various densities, where the radii of the fractures were sampled from a truncated power-law distribution, and whose parameters were loosely based on field site characterizations. We also considered five network densities, which were defined using a dimensionless version of density based on percolation theory. Once the networks were generated, we upscaled them into a single continuum model using the upscaled discrete fracture matrix model presented by Sweeney et al. (2019). We considered steady, isothermal pressure-driven flow through each domain and then simulated conservative, decaying, and adsorbing tracers using a pulse injection into the domain. For each simulation, we calculated the effective permeability and solute breakthrough curves as quantities of interest to compare between network realizations. We found that selecting a mesh resolution such that the global topology of the upscaled mesh matches the fracture network is essential. If the upscaled mesh has a connected pathway of fracture (higher permeability) cells but the fracture network does not, then the estimates for effective permeability and solute breakthrough will be incorrect. False connections cannot be eliminated entirely, but they can be managed by choosing appropriate mesh resolution and refinement for a given network. Adopting octree meshing to obtain sufficient levels of refinement leads to fewer computational cells (up to a 90% reduction in overall cell count) when compared to using a uniform resolution grid and can result in a more accurate continuum representation of the true fracture network.
Happy Together? On the Relationship Between Research on Retrieval Practice and Generative Learning Using the Case of Follow-Up Learning Tasks

Published: October 2023

AbstractGenerative learning activities are assumed to support the construction of coherent mental representations of to-be-learned content, whereas retrieval practice is assumed to support the consolidation of mental representations in memory. Considering such functions that complement each other in learning, research on how generative learning and retrieval practice intersect appears to be very fruitful. Nevertheless, the relationship between these two fields of research is “expandable”—research on generative learning and retrieval practice has been pursued so far largely side by side without taking much note of each other. Against this background, the present article aims to give this relationship a boost. For this purpose, we use the case of follow-up learning tasks provided after learners have processed new material in an initial study phase to illustrate how these two research strands have already inspired each other and how they might do so even more in the future. In doing so, we address open- and closed-book formats of follow-up learning tasks, sequences of follow-up learning tasks that mainly engage learners in generative activities and tasks that mainly engage learners in retrieval practice, and discuss commonalities and differences between indirect effects of retrieval practice and generative learning activities. We further highlight what we do and do not know about how these two activity types interact. Our article closes with a discussion on how the relationship between generative learning and retrieval practice research could bear (more and riper) fruit in the future.
Shame, entitlement, and the systemic racism of mathematics “ability” grouping in Aotearoa New Zealand

AbstractDecades of research has documented the consequences of allocating school students into a hierarchy of classes with narrow ranges of mathematics attainment, a process known as streaming, tracking, setting, or “ability” grouping. The purported benefits of streaming are inconsistent and disputed, but the harms are clear, in particular, (1) the limiting curriculum often available in low streams and (2) the loss of self-confidence that results from being positioned in a low stream. Building on this foundation, we discuss streaming in mathematics as tied to systemic racism in Aotearoa New Zealand, where the harmful effects of streaming fall most heavily on Māori and Pasifika students. Previous analyses of race and streaming have focused primarily on the racial composition of streamed classes, bias in stream allocation, and racialised teacher expectations in streamed settings. In contrast, we focus on the emotional consequences of streaming, arguing that streaming produces racialised emotions of shame and entitlement as unintended but predictable consequences. We illustrate the racialised production of entitlement and shame through collaborative storying, interweaving our own biographies with a re-analysis of student interviews from two prior studies.
Computation offloading for ground robotic systems communicating over WiFi – an empirical exploration on performance and energy trade-offs

Published: October 2023

AbstractContextRobotic systems are known to perform computation-intensive tasks with limited computational resources and battery life. Such systems might benefit from offloading heavy workloads to the Cloud; however, in some cases, this implies high network traffic that degrades performance and energy consumption.GoalIn this study, we aim at evaluating the impact of different computation offloading strategies on performance and energy consumption in the context of autonomous robots.MethodWe conduct two controlled experiments involving a robotic mission based on the Turtlebot3 robot and ROS 1. The mission consists of three tasks that are recurrent in robotics and good candidates for computation offloading in research, namely, SLAM mapping, navigation stack, and object recognition. Each of the tasks is either executed on board or offloaded in a full-factorial experiment design. The obtained measures are then statistically analyzed.ResultsThe results show that offloading the object recognition task causes a more significant decrease in resource utilization and energy consumption than both SLAM mapping and navigation. However, object recognition affects the volume of network traffic significantly to the extent that it can easily cause network congestion.ConclusionsIn the context of our experiments (i.e.,those involving small-scale ground ROS-based mobile robots operating under WiFi networks), offloading object recognition is beneficial in terms of performance and energy consumption. Nevertheless, large network bandwidth needs to be available for object recognition offloading. While the image resolution and frame rate have a significant impact on not only the network traffic but also energy consumption and performance, these parameters need to be carefully set so that the results of this task can be always received in time, which is particularly crucial in real-time systems.
Not a Good Fix: Constitutivism on Value Change and Disagreement
Authors: Klenk Michael , de Poel Ibo van 
Published: October 2023

AbstractWe examine whether Thomsonian constitutivism, a metaethical view that analyses value in terms of ‘goodness-fixing kinds,’ i.e. kinds that themselves set the standards for being a good instance of the respective kind, offers a satisfactory explanation of value change and disagreement. While value disagreement has long been considered an important explanandum, we introduce value change as a closely related but distinct phenomenon of metaethical interest. We argue that constitutivism fails to explain both phenomena because of its commitment to goodness-fixing kinds. Constitutivism explains away disagreement and at best explains the emergence of new values, not genuine change. Therefore, Thomsonian constitutivism is not a good fix for realist problems with explaining value disagreement, and value change.
Nitrogen fertilizer replacement values of organic amendments: determination and prediction
Authors: Westerik Dorien , Hoffland Ellis , Hijbeek Renske 
Published: October 2023

AbstractThe nitrogen fertilizer replacement value (NFRV) quantifies the value of organic amendments as a nitrogen (N) fertilizer, and is commonly defined as the extent to which organic fertilizer N can replace mineral fertilizer N. NFRVs can be calculated by comparing the crop N uptake from equal N application rates of mineral and organic fertilizer, or by comparing the N rates of both fertilizers needed to obtain equal crop N uptake. Currently, NFRVs are mainly known for animal manure, whereas other organic waste products may become available as fertilizer products in the future. In this study, a pot experiment with spring wheat was performed to (1) assess NFRVs of a range of organic amendments; (2) compare NFRVs based on equal N application with NFRVs based on equal N uptake; and (3) assess which product characteristics explain observed variation. Observed NFRVs varied between 6.2 and 78.8%, with the lowest value for raw food waste and the highest for fishmeal. NFRVs were overestimated when calculated based on equal N application rate (with on average 6.9% point), and more so at high N application rate (9.0% point). NFRVs should therefore be calculated based on equal N uptake from organic and mineral fertilizers. Nitrogen concentration of the organic fertilizer provided the best explanation of variation observed in NFRVs (R2 = 0.86). These findings give valuable insights into the large variation in value of organic waste streams as organic fertilizer and can support decisions on sustainable N application rates, to increase crop N uptake and reduce N losses to the environment.
Reliable and inexpensive dissolved oxygen sensing materials

Published: October 2023

AbstractBare, non-pretreated platinum wires and screen-printed platinum electrodes were used as both working and counter electrodes in the measurement of dissolved oxygen using a chronoamperometric method. The oxygen reduction current response in the diffusion state was used for a linear determination of air saturation. We evaluated the two different materials in general for their sensing performance such as conditioning time, accuracy, resolution and stability over 13 h of continuous mid-term measurement. A good performance was found for the wire electrodes in terms of accuracy with a current slope of 1.0–1.6 µA (% as)-1 and a resolution of 10–15 nA (Lowest Level of Detection = 0.1% as), but with an unstable current response result over the course of the measurement. The screen-printed electrodes have a resolution of 10–18 nA (Lowest Level of Detection = 0.6–0.8% as) and an accuracy of 620–660 nA (% as)-1 but they showed promising reproducibility and stability. Both materials require several hours of conditioning in the chronoamperometric method before a stable current response is achieved. For biotechnological applications, the platinum screen printed electrodes were evaluated in typical parameter settings (pH 4.0 and 7.4, salinity 0.1 to 10x phosphate buffered saline and temperature 12 to 42 °C) and showed correlations between the response time and stability and the temperature. No correlations were found between salinity, pH and the current response. In this paper, we present inexpensive electrode materials and a simple to implement chronoamperometric method for reliable direct measurement of dissolved oxygen in aqueous media.

Published: October 2023

Abstract
Participation in Organised Extracurricular Social Activities (OESA) can provide positive outcomes for children. This study investigated whether children aged 4 to 12 years diagnosed with autism differ in their OESA participation and experience compared to neurotypical peers. Parents of autistic children (n = 35) and those of neurotypical peers (n = 171) responded to questions that asked them to reflect on their child’s participation and experiences in OESAs. Parents of autistic children reported significantly less OESA participation compared to parents of neurotypical children. Additionally, when evaluating factors that facilitated OESA participation, parents of autistic children rated their child’s individual abilities and behaviour, the OESA’s features, and the social environment less positively, compared to parents of neurotypical children. OESA participation and experiences differ for autistic and neurotypical children. This study identifies factors that can be adjusted to mitigate this difference.
Automation, Alignment, and the Cooperative Interface
Authors: Jonker Julian David 
Published: October 2023

AbstractThe paper demonstrates that social alignment is distinct from value alignment as it is currently understood in the AI safety literature, and argues that social alignment is an important research agenda. Work provides an important example for the argument, since work is a cooperative endeavor, and it is part of the larger manifold of social cooperation. These cooperative aspects of work are individually and socially valuable, and so they must be given a central place when evaluating the impact of AI upon work. Workplace technologies are not simply instruments for achieving productive goals, but ways of mediating interpersonal relations. They are aspects of a cooperative interface i.e. the infrastructure by which we engage cooperative behavior with others. The concept of the cooperative interface suggests two conjectures to foreground in the social alignment agenda, motivated by the experience of algorithmic trading and social robotics: that AI impacts cooperation through its effects on social networks, and through its effects on social norms.
Trajectories to Suicide Following Intimate Partner Violence Victimization: Using Structural Equation Modelling to Examine Suicide and PTSD in Female Emergency Department Users

Published: October 2023

Abstract
Purpose
Intimate partner violence (IPV) is known to increase the risk of suicidal thoughts and behaviors. Despite the urgent need to increase women’s safety and wellbeing, trajectories to suicide are not well understood and few studies have tested potentially important mediators, such as post-traumatic stress disorder (PTSD), that could help to improve risk stratification and clinical responses.

Methods
This study used baseline data from a prospective cohort study (2019–2020) to examine differential effects of psychological, physical, sexual, and multiple IPV on suicidal ideation and suicide attempt and test whether pathways are mediated by PTSD. Simple random sampling – online/in-person in Australian emergency departments (EDs) – was used to survey consenting women with a recent suicide-related ED presentation. Structural equation modelling was used to test the pathways between recent and lifetime IPV, PTSD, and suicidal ideation and attempt.

Results
Of the 1,715 women (M = 30.24, SD = 11.91 years) who participated, 1,012 (59%) reported lifetime IPV exposure, with 608 (35%) reporting recent victimization (< 18 months). Presence of PTSD wholly mediated the effects of psychological, physical, and sexual IPV on ideation (p < .05). Multiple IPV was unique in its direct effects on ideation and attempt and these pathways were most consistent for recent IPV, compared with lifetime exposure (p < .05).

Conclusions
Pathway analysis identified two high-risk patient-populations: Women with recent multiple IPV and those with a diagnosis of PTSD following lifetime IPV exposure. Findings can be used to improve risk prediction and clinical intervention for patients living with mortality risk from partner- and self-directed violence.
