Do We Use Relatively Bad (Algorithmic) Advice? The Effects of Performance Feedback and Advice Representation on Advice Usage
Authors: Daschner Stefan , Obermaier Robert 
Published: November 2024

ABSTRACTAlgorithms are capable of advising human decision‐makers in an increasing number of management accounting tasks such as business forecasts. Due to expected potential of these (intelligent) algorithms, there are growing research efforts to explore ways how to boost algorithmic advice usage in forecasting tasks. However, algorithmic advice can also be erroneous. Yet, the risk of using relatively bad advice is largely ignored in this research stream. Therefore, we conduct two online experiments to examine this risk of using relatively bad advice in a forecasting task. In Experiment 1, we examine the influence of performance feedback (revealing previous relative advice quality) and source of advice on advice usage in business forecasts. The results indicate that the provision of performance feedback increases subsequent advice usage but also the usage of subsequent relatively bad advice. In Experiment 2, we investigate whether advice representation, that is, displaying forecast intervals instead of a point estimate, helps to calibrate advice usage towards relative advice quality. The results suggest that advice representation might be a potential countermeasure to the usage of relatively bad advice. However, the effect of this antidote weakens when forecast intervals become less informative.

AbstractIndium–salen complexes with electron‐donating 9,9‐dimethyl‐9,10‐dihydroacridine (DMAC) groups at positions 4 (DMACIn1) and 4 and 6 (DMACIn2) were synthesized and characterized to investigate the effect of the substituents number and structural rigidity on photophysical properties. The single crystal structure of DMACIn1 revealed highly twisted arrays (83–89°) between the DMAC groups and salen moieties and a nearly square‐pyramidal geometry around the indium center. Both complexes exhibited green fluorescence in toluene at 298 K and in rigid states (in toluene at 77 K and in a film), which originates from intramolecular charge transfer (ICT) transitions. The absolute photoluminescence quantum yields (PLQYs) of DMACIn1 and DMACIn2 were low in solution but high in the rigid states. The film‐state PLQY of DMACIn2 (59.5%) was more than five‐fold higher than that of DMACIn1 (11.1%). A similar result was observed in toluene at 77 K. These findings were rationalized in terms of the beneficial effects of structural rigidity and higher number of DMAC donors on ICT‐based radiative decay. The experimental results agreed with those of computational studies.

ABSTRACTRegulatory authorities are putting a lot of pressure on manufacturers to devise strategies to boost their contribution to the circular economy. The limited comprehension surrounding the complex interplay that exists between the deployment of Industry 4.0 (I4.0) strategies, the capability to acquire information, and the ability to balance exploration and exploitation activities within an organization acts as a barrier for manufacturers to attain the optimal levels of organizational performance. As a result, the purpose of the current investigation is to investigate the strategic execution of I4.0 on manufacturers' information acquisition capability in order to foster the ambidexterity required to flourish in the innovation‐driven high‐performance ecosystem for attaining circular economy performance. In this study, data from a cross‐sectional survey that included responses from a sample of 238 Indian manufacturers were assessed using structural equation modeling. According to the results, I4.0 technologies assist organizations in strengthening their exploitative and explorative capabilities, allowing them to achieve success in innovation, which is directly related to their performance in circular economy activities. Unexpectedly, the association between an organization's information acquisition capability and its innovation performance is not substantial, but it is completely mediated by both exploitative and explorative capabilities, which are characterized as organizational ambidexterity.

ABSTRACTBackgroundDespite growing evidence of its clinical implications, assessment of coronary microvascular dysfunction (CMD) remains limited in routine clinical practice. Hence, there is an increasing interest in angiography‐derived indices to encourage assessment of CMD in the cardiac catheterisation laboratory.AimsWe investigate here an alternative approach, using a combination of pressure‐wire‐based assessment of distal coronary pressure (Pd) and an angiography‐derived surrogate of coronary flow, to derive a hybrid index of microcirculatory resistance (IMRhybrid).MethodsPatients enroled prospectively under the Oxford Acute Myocardial Infarction (OxAMI) study were included in the OxAMI HYBRID substudy. The accuracy of IMRhybrid was assessed in diagnosing CMD using bolus thermodilution‐based Index of Microcirculatory Resistance (IMR) as a reference. The accuracy of IMRhybrid was then compared against a fully angiography‐derived index of microvascular resistance (IMRangio).ResultsOne hundred and eighty six patients were enroled, of which 121 with acute coronary syndrome and 65 with stable coronary artery disease. A total of 240 vessel analyses were performed. Both IMRhybrid and IMRangio correlated with IMR (rho = 0.71, p < 0.001 and rho = 0.71, p < 0.001 respectively) and showed good and comparable overall diagnostic accuracy in predicting IMR ≥ 25 (80.8% and 83.1% respectively) with a receiver operator curve (ROC) analyses showing similar AUC of 0.86 (95% CI 0.82–0.91, p < 0.001) for IMRhybrid and 0.86 (95% CI 0.809–0.906, p < 0.001) for IMRangio, p for comparison = 0.641.ConclusionBoth approaches, IMRhybrid and IMRangio are viable and comparable indices correlating with bolus thermodilution‐based IMR and retaining good diagnostic accuracy. IMRhybrid specifically is a simple alternative to conventional bolus thermodilution‐based IMR applicable to any pressure wire system.

AbstractWe present the preparation and investigation of a fluorine‐free surface‐active bis‐N‐heterocyclic carbene (NHC) platinum(II) complex — trans‐[Pt(mPEG3C8Im)2Cl2] — for interface‐enhanced supported ionic liquid phase (SILP) catalysis within a group of (mPEGn)‐substituted ionic liquids (ILs) ([(mPEGn)2Im][A] ILs). The complex was characterized by means of single‐crystal X‐ray diffraction (scXRD) analysis and multinuclear (1H, 13C, 195Pt) NMR spectroscopy, indicating the presence of two almost equimolar syn–anti‐rotamers of the square‐planar complex in solution. Angle‐resolved X‐ray photoelectron spectroscopy (ARXPS) revealed pronounced interface‐accumulation of trans‐[Pt(mPEG3C8Im)2Cl2] in IL solutions of [(mPEG2)2Im][A] (A−=I− and PF6−).

Published: November 2024

AbstractThe mechanical actuation of smart materials has garnered considerable attention in biological and medical research due to their ability to mimic biological processes at both molecular level, such as conformational changes in individual compounds, and at the macroscopic level, where polymeric substrates respond to external stimuli. In this study, we present a polymeric composite incorporating a novel urea macrocycle as a filler, forming a soft actuator that responds to various organic solvent vapors. The underlying actuation mechanism is attributed to crystalline phase transition of urea macrocycle, driven by the host–guest interactions with diverse guest molecules. This work provides valuable insights for advancing the design of supramolecular hosts in smart material applications.

Comprehensive Summary3,3‐Disubstituted oxindoles, forming the core of extensive bioactive natural products and drugs, attract tremendous efforts to develop efficient methods for their preparation. Here, a photocatalyst‐free approach for the synthesis of 3,3‐disubstituted oxindoles via a substrate‐photosensitive strategy under visible light was successfully developed. Preliminary mechanistic studies illustrated that isatin‐derived imines can be directly excited by visible light to generate strong oxidant states, facilitating subsequent single‐electron transfer (SET) processes with Hantzsch esters to afford the corresponding α‐amino radical intermediates. Thus, these α‐amino radicals promote the subsequent Giese radical addition or radical/radical cross‐coupling reactions to furnish diverse functionalized 3‐substituted 3‐aminooxindoles in high yields.

ABSTRACTAimA recent European Heart Rhythm Association (EHRA) practical guide provides guidance on the use of novel digital devices for heart rhythm analysis using either electrocardiogram (ECG) or photoplethysmography (PPG) technology for the diagnosis of atrial fibrillation (AF). This survey assesses physicians' preferences to use digital devices in patients with possible AF and their impact on clinical decision‐making.Methods and ResultsParticipants of the DAS‐CAM III initiated and distributed an online survey assessing physician preferences in using digital devices for the management of AF in different clinical scenarios. A total of 505 physicians (median age: 38 [IQR 33–46] years) from 30 countries completed the survey. A third of respondents were electrophysiologists, the others were cardiologists, cardiology residents, or general practitioners. Electrophysiologists were more likely to have experience with both ECG‐based (92% vs. 68%, p < 0.001) and PPG‐based (60% vs. 34%, p < 0.001) digital devices. The initial diagnostic approach to each scenario (symptomatic low‐risk, symptomatic high‐risk, or asymptomatic high‐risk patient) was heterogeneous. Electrophysiologists preferred intermittent single‐lead ECG monitoring to traditional Holter ECGs to screen for AF. Both electrophysiologists and non‐electrophysiologists would rarely use PPG‐based devices to diagnose and screen for AF (8.2%–9.8%). Electrophysiologists and non‐electrophysiologists use ECG‐based technology to confirm PPG‐documented tracings suggestive of AF.ConclusionWhile PPG‐based digital devices are rarely used for diagnosis and screening for AF, intermittent ECG‐based digital devices are beginning to be implemented in clinical practice. More education on the potential of novel digital devices is required to achieve diagnostic pathways as suggested by the EHRA practical guide.

ABSTRACTA high‐sensitivity and low start‐up voltage cold‐start circuit for wireless power harvesting is presented in this work. To improve conversion efficiency and reduce charge pump stages, a pipeline power supply uplifting clocking (PPSUC) driving scheme is proposed, which improves the conversion efficiency more than 45%. By adopting a two‐stage PPSUC driving Pelliconi charge pump, the proposed cold‐start circuit is designed and verified in a commercial 65‐nm MCOS process. Benefiting from the proposed PPSUC driving scheme, the cold‐start circuit demonstrates a low start‐up voltage of 170 mV and a high cold stat sensitivity of −32 dBm.

AbstractIntroductionAs global population ages, frailty has surfaced as a major public health challenge. Given the heterogeneity of frailty in the clinical presentation, it is imperative to develop personalised diagnostic and treatment strategies. The traditional Chinese medicine (TCM) constitution offers notable advantages in discerning individual differences. This study aims to elucidate the association between TCM constitutions and frailty, providing insights into the application of TCM for the frailty management.MethodsAn observational study was conducted at Huadong hospital from July 2022 to November 2023. A total of 241 older patients were recruited. Each patient underwent assessments for the TCM constitution and frailty status. Comprehensive data collection encompassed medical history, biochemical indicators, bone mineral density (BMD), body composition and physical performance metrics. Plasma samples were also collected to detect levels of inflammatory factors and lymphogenesis‐related factors, including IL‐1β, TNF‐α, VEGF‐C, ANGPTL4 and ACV‐A. Multi‐level statistical analysis was used to establish the relationship of TCM constitutions with frailty.ResultsAmongst all participants, 54 individuals were classified as non‐frail, 90 individuals as pre‐frail and 97 individuals as frail. Regression analysis indicated that frailty was closely associated with four imbalanced TCM constitutions: Qi deficiency, phlegm dampness, blood stasis and Qi depression. Subsequent analysis demonstrated that Qi deficiency was associated with decreased BMD, phlegm dampness with elevated high‐density lipoprotein levels, Blood stasis with elevated blood glucose levels, and Qi depression with both decreased BMD and elevated low‐density lipoprotein levels. Furthermore, individuals characterised by imbalanced TCM constitutions exhibited inferior handgrip strength, walking pace, lower limb strength and higher levels of inflammatory factors and lymphogenesis‐related factors compared to those with balanced TCM constitution.ConclusionFrailty is independently associated with Qi deficiency, phlegm dampness, blood stasis and Qi depression. Personalised diagnostic approaches based on the TCM constitution may offer valuable insights for directing treatment for older patients with frailty.

Published: November 2024

ABSTRACTColoniality is strongly shaped by aspects of social foraging behaviour. For example, colonies may be important sources of information, while food competition may increase foraging efforts and limit colony size. Understanding foraging ecology considering these apparent trade‐offs is required to develop a better understanding of colonial living. We combined animal‐borne GPS, cameras and dive recorders to study social foraging in breeding adult northern gannets Morus bassanus—a wide‐ranging colonial seabird. We first tested for indirect evidence of prey depletion around the colony by estimating dive location, depth and duration. Next, we tested for sociality during different behaviours (commuting, foraging and resting) and distance from the colony. Finally, we quantified flocks of inbound and outbound birds to compare social foraging between outbound and inbound legs of the commute. Dive probability and depth (n = 46 individuals; n = 1590 dives) increased with distance from the colony, creating dive clusters at ~100 and 180 km consistent with conspecific prey depletion. Camera stills (n = 8 individuals; n = 7495 images) show gannets are highly social, but this varied among behaviours. Sociality was highest during foraging and commuting; especially inbound and social foraging was more likely far from the colony. Gannets were equally likely to be solitary or social when leaving the colony but returning birds were more likely in larger flocks. In summary, despite experiencing intraspecific competition for food, gannets engage in dynamic, context‐dependent social foraging associations. Conspecifics aggregated far from the colony possibly because of a prey depletion halo closer to home, but this provided potential benefits via local enhancement and by returning to the colony in flocks. Our results therefore illustrate how competition may, paradoxically, facilitate some aspects of group foraging in colonial animals.
Assessment of Climate Change Impacts on the Distribution of Endangered and Endemic Changnienia amoena (Orchidaceae) Using Ensemble Modeling and Gap Analysis in China

ABSTRACTClimate change has significant impacts on the distribution of orchids. The endemic and endangered orchids are more susceptible to climate change than widely distributed orchids. To date, little is known concerning the response of endangered Changnienia amoena, endemic to China, to different climate scenarios. Here, we build an ensemble model comprising random forest model, maximum entropy model, and gradient boosting model in Biomod2 package to project its potential distribution in China, evaluate its current protective effectiveness, and identify its conservation gaps in China by determining the C. amoena population range within the natural protected areas. The outcomes showed that the four key environmental factors influencing its distribution were mean diurnal temperature range, minimum temperature of the coldest month, temperature seasonality, and precipitation of the warmest quarter. This orchid was currently distributed mainly in southern Anhui, central and western Hubei, western Hunan, southern Shaanxi, and eastern Sichuan province. The total suitable area of C. amoena was 58.33 × 104 km2, only accounting for 6.08% of China's total territory, which is larger than known. However, only 4.48% of the suitable area is located within national nature reserves and 3.33% within provincial nature reserves, respectively. During the last inter glacial and mid‐holocene, its suitable areas were larger than the current. Under six future climate scenarios, its suitable areas may decrease averagely by 2.26% relative to the current, with severe habitat fragmentation. Collectively, the centroid of C. amoena is expected to shift towards the southeast in the future. Therefore, our findings demonstrate that climate change has an adverse effect on its potential distribution. We recommend expanding protected areas or establishing new conservation sites for C. amoena in China. Furthermore, our study can help to inform the development of conservation management strategies for other endangered Chinese endemic orchids under climate change.

AbstractEcosystems worldwide are experiencing a range of natural and anthropogenic disturbances, many of which are intensifying as global change accelerates. Ecological responses to those disturbances are determined by both the vulnerabilities of species and their interspecific interactions. Understanding how individual species contribute to the (in‐)stability of an aggregated community property, or function, is fundamental to ecological management and conservation. Here, we present a framework to identify species contributions to stability based on their absolute and relative responses to disturbances. Using simulations, we show that these two dimensions enable identification of (de‐)stabilizing species and reveal that competitive dominance determines the magnitude of both absolute and relative contributions to stability. Applying our framework to empirical data from a multi‐site mesocosm experiment showed that species contributions varied among treatments, sites, and seasons. Despite this dependency on both biotic and abiotic contexts, species contributions were generally constrained by their relative dominance in undisturbed conditions. Rare species contributed positively to stability, while dominant species contributed negatively, indicating compensatory dynamics. Our framework offers an important step toward a more mechanistic understanding of ecological stability based on species performance.

Published: November 2024

AbstractPalladium‐catalyzed intermolecular [5+2] cycloaddition of propargylic carbonates with benzyl allenyl ethers has been developed for the synthesis of allene‐containing 2‐benzoxepines. The reaction proceeds by a pathway involving decarboxylative allenylpalladium formation, regioselective intermolecular insertion, and intramolecular nucleophilic attack. In this way, the sequential formation of C−C and C−O bonds results in the generation of a 2‐benzoxepine skeleton in a one‐pot process.
1,4‐Dioxane as Precursor of −CH2CH2−: A Simple and Convenient Strategy to Synthesize 1,2‐Disulfide Substituted Ethanes Initiated by Iodine

Published: November 2024

AbstractAn unprecedented I2‐initiated nucleophilic ring opening reaction of 1,4‐dioxane with thiols for the construction of various 1,2‐disulfide substituted ethanes has been developed. Previously, dihalogenated ethane, acetylene or ethylene are often used as the pre‐cursor of −CH2CH2−. Through the cleavage of two C−O bonds, 1,4‐dioxane as precursor of −CH2CH2− has been achieved for the first time. In the presence of HI, thiols could be replaced by disulfides as nucleophile. This protocol is very convenient and practical by its simple and mild conditions.
