The diversity of divestiture– stock market reactions around the announcements of divestiture programs
Authors: Erl Ludwig , Kiesel Florian , Schiereck Dirk 
Published: December 2024

AbstractSingle divestitures can adjust a firm’s strategy, while divestiture programs, a series of divestitures with a common rationale, may considerably change a firm’s business. However, this does not always imply a positive impact. Existing evidence on how capital markets evaluate these decisions lacks validation based on the firm’s strategic background. This paper fills this gap by examining stock market reactions to divestiture program announcements, conditional on the firm’s current situation. We explore five key antecedents likely to influence divestiture program decisions: CEO turnover, new blockholder, financial distress, prior divestiture experience, and industry divestiture waves. Examining more than 100 European firms and their divestiture disclosures, our results show that firms announce divestiture programs when financially distressed or after a change in the top management. Market reactions vary but are more positive when program value is disclosed, especially for financially driven programs or those programs which are part of broader restructuring initiatives.

Published: December 2024

AbstractWe investigated the cost-effectiveness of treating iron deficiency anemia (IDA) with ferric citrate hydrate (FC) in Japan. We employed four treatment strategies: switching from sodium ferrous citrate (SF) to FC at (1) 500 mg (approximately 120 mg of iron) per day or (2) 1000 mg (approximately 240 mg of iron) per day in patients with SF-induced nausea/vomiting, or starting treatment with FC at (3) 500 mg/day or (4) 1000 mg/day. We evaluated the cost-effectiveness of these strategies compared with SF 100 mg (100 mg of iron) per day. Incremental effects over 26 weeks relative to SF 100 mg were 0.0052 quality-adjusted life years (QALYs) for (1) and (2), and 0.0044 QALYs for (3) and (4). From the payer’s perspective, incremental cost-effectiveness ratios (ICERs: JPY/QALY) against SF 100 mg were: (1) 1,107,780, (2) 2,257,477, (3) 5,588,430, and (4) 11,544,816. All four FC strategies were dominant (less costly and more effective) from a limited societal perspective. Treatment with FC for IDA was cost-effective (ICER ≤ JPY 5,000,000/QALY) when switching strategies from the payer perspective, and cost-saving (all FC strategies) from limited societal perspectives. Individual patients' characteristics and cost-effectiveness should be considered in treatment selection.
Influence of pores on the fatigue life of welded joints and investigation of acceptance criteria defined in standard documents
Authors: Jung Matthias , Fenzl René 
Published: December 2024

Abstract
Inner defects in welded joints constitute concurrent sites for fatigue failure in welds, especially when high fatigue resistance is enforced at weld toe and root. Existing standards limit the size of pores and other inner defects in proportion to the sheet or weld thickness, but for larger dimensions cutoff values are in place. This leads to overly high acceptance criteria when it comes to thicker sheets, as for example those used for wind turbine towers. To analyze the influence of pores on the fatigue life, specimens with targeted pore sizes larger than the usually accepted were tested under fatigue loading. In the present study, a numerical model for fatigue assessment was developed based on the experimental results, which allowed further variance of pore sizes and locations. It is shown, that for larger weldments the acceptable pore size can be increased by up to 87.5 % without the necessity to reduce the applicable design curve. But, the location of the pore with regard to the specimens surface has a large influence, with pores in a distance to the surface smaller than 13 % of the sheet thickness leading to a reduction in the applicable design curve by up to 4 FAT classes — an effect that is currently not considered in common weld quality documents.
Four Key Questions to Guide Human Rights–based Social Listening during Infodemics
Authors: Forman Lisa 
Published: December 2024

AbstractThis paper considers what a human rights–based approach to the use of social listening to counter infodemics during a serious health threat might entail, using COVID-19 as a primary example. The paper considers social listening in the context of human rights including health, life, free speech, and privacy, and outlines what a rights-compliant form of social listening to infodemics might entail. The paper argues that human rights offer guardrails against illicit and unethical forms of social listening as well as signposts towards a more equitable, ethical, and effective public health tool. The paper first expands on the human rights dimensions of COVID-19, infodemics, and social listening. Second, it considers the human rights dimensions of social listening in relation to rights to health, life, and free speech, given international human rights law principles for limiting these rights. Finally, using this framework, the paper poses four key questions to frame a rights-based approach to social listening: Why do we listen? How do we listen? Who do we listen to and who is doing the listening? And what are the outcomes of such listening?
“Faith it, till you make it”: Prosperity Gospel and Spiritual Hustling among Young Pentecostal Christians in Harare
Authors: Taru Josiah , McNeill Fraser G. 
Published: December 2024

AbstractPentecostal charismatic churches that preach prosperity gospel in Zimbabwe have attracted a youthful membership. In the context of a deeply uncertain economic future, young Pentecostal Christians devise performativity strategies for optimizing their chances of converting prosperity gospel into material prosperity. These strategies include sartorial elegance in adorning counterfeit suits, the performance of obedience, and the use of social media technologies. The picture that emerges is a complex and at times contradictory one in which the potential realization of upward spiritual and social mobility rests, ultimately, on the transformative and volatile nature of value. Data for this project was collected in Harare through ethnographic research and interviews over a year-long period.
Expressed disapproval does not sustain long-term cooperation as effectively as costly punishment
Authors: Sparks Adam , Burleigh Tyler , Barclay Pat 
Published: December 2024

Abstract
Punishment plays a role in human cooperation, but it is costly. Prior research shows that people are more cooperative when they expect to receive negative feedback for non-cooperation, even in the absence of costly punishment, which would have interesting implications for theory and applications. However, based on theories of habituation and cue-based learning, we propose that people will learn to ignore expressions of disapproval that are not clearly associated with material costs or benefits. To test this hypothesis, we conducted a between-subjects, 40-round public goods game (i.e. much longer than most studies), where participants could respond to others’ contributions by sending numerical disapproval messages, paying to reduce others’ earnings, or neither. Consistent with previous results, we observed steadily increasing contributions in the costly punishment condition. In contrast, contributions declined after the early rounds in the expressed disapproval condition, and were eventually no higher than the basic control condition with neither costly punishment nor disapproval ratings. In other words, costless disapproval may temporarily increase cooperation, but the effects fade. We discuss the theoretical and applied implications of our findings, including the unexpectedly high levels of cooperation in a second control condition.
Generation of multi-watt sub-50 fs pulses in Mamyshev oscillators: influence of the central wavelength in the grating filter

Published: December 2024

Abstract
Mamyshev oscillators (MOs) exhibit the potential for generating high average power and ultrashort pulses. Herein, we construct an MO using flexible double-cladding ytterbium-fiber with a fusion-spliced-combiner pumped scheme. Consistent with the most reported research results, the offset filter separation significantly affects the pulse characteristics (spectrum, pulse duration, etc.). Notably, in comparison with red-shifting, blue-shifting the peak spectral emission of the grating filter relative to a constant central wavelength of the bandpass filter substantially enhances the laser output characteristics. This phenomenon, which has not been previously reported, results in an average power up to 2.23 W and a pulse duration as short as 49 fs. To our knowledge, this is the highest average power achieved in sub-50 fs pulse duration in the nonlinear polarization rotation-assisted mode-locked MO laser architecture. The presented technique offers unique scientific proof for developing ultrafast laser sources with higher average power and shorter pulse duration.
Modelling DSA, FAST, and CRAFT surveys in a z-DM analysis and constraining a minimum FRB energy

Published: December 2024

Abstract
Fast radio burst (FRB) science primarily revolves around two facets: the origin of these bursts and their use in cosmological studies. This work follows from previous redshift–dispersion measure (z–DM) analyses in which we model instrumental biases and simultaneously fit population parameters and cosmological parameters to the observed population of FRBs. This sheds light on both the progenitors of FRBs and cosmological questions. Previously, we have completed similar analyses with data from the Australian Square Kilometer Array Pathfinder (ASKAP) and the Murriyang (Parkes) Multibeam system. In this manuscript, we use 119 FRBs with 29 associated redshifts by additionally modelling the Deep Synoptic Array (DSA) and the Five-hundred-metre Aperture Spherical radio Telescope (FAST). We also invoke a Markov chain Monte Carlo (MCMC) sampler and implement uncertainty in the Galactic DM contributions. The latter leads to larger uncertainties in derived model parameters than previous estimates despite the additional data and indicate that precise measurements of DM

$_\textrm{ISM}$

will be important in the future. We provide refined constraints on FRB population parameters and derive a new constraint on the minimum FRB energy of log

$E_{\mathrm{min}}$

(erg)=39.47

$^{+0.54}_{-1.28}$

which is significantly higher than bursts detected from strong repeaters. This result likely indicates a low-energy turnover in the luminosity function or may alternatively suggest that strong repeaters have a different luminosity function to single bursts. We also predict that FAST will detect 25–41% of their FRBs at

$z \gtrsim 2$

and DSA will detect 2–12% of their FRBs at

$z \gtrsim 1$

Population synthesis of hot-subdwarf B stars with COMPAS: Parameter variations and a prescription for hydrogen-rich shells
Authors: Rodríguez-Segovia Nicolás , Ruiter Ashley J. , Seitenzahl Ivo R. 
Published: December 2024

Abstract
Subdwarf B stars are a well-known class of hot, low-mass stars thought to be formed through interactions in stellar binary systems. While different formation channels for subdwarf B stars have been studied through a binary population synthesis approach, it has also become evident that the characteristics of the found populations depend on the initial set of assumptions that describe the sometimes poorly constrained physical processes, such as common envelope episodes or angular momentum loss during mass transfer events. In this work we present a parameter study of subdwarf B populations, including a novel analytic prescription that approximates the evolution of subdwarf B stars with hydrogen-rich outer shells, an element previously overlooked in rapid binary population synthesis. We find that all studied parameters strongly impact the properties of the population, with the possibility of igniting helium below the expected core-mass value near the tip of the red giant branch strongly affecting the total number of subdwarf B candidates. Critically, our newly proposed prescription for the evolution of subdwarf B stars with hydrogen-shells helps to reconcile theoretical predictions of surface gravity and effective temperature with observational results. Our prescription is useful in the context of rapid binary population synthesis studies and can be applied to other rapid binary population synthesis codes’ output.
Calcium-binding site in AA10 LPMO from Vibrio cholerae suggests modulating effects during environmental survival and infection

Abstract
Despite major efforts toward its eradication, cholera remains a major health threat and economic burden in many low- and middle-income countries. Between outbreaks, the bacterium responsible for the disease, Vibrio cholerae, survives in aquatic environmental reservoirs, where it commonly forms biofilms, for example, on zooplankton. N-acetyl glucosamine-binding protein A (GbpA) is an adhesin that binds to the chitinaceous surface of zooplankton and breaks its dense crystalline packing thanks to its lytic polysaccharide monooxygenase (LPMO) activity, which provides V. cholerae with nutrients. In addition, GbpA is an important colonization factor associated with bacterial pathogenicity, allowing the binding to mucins in the host intestine. Here, we report the discovery of a cation-binding site in proximity of the GbpA active site, which allows Ca2+, Mg2+, or K+ binding close to its carbohydrate-binding surface. In addition to the X-ray crystal structures of cation-LPMO complexes (to 1.5 Å resolution), we explored how the presence of ions affects the stability and activity of the protein. Calcium and magnesium ions were found to bind to GbpA specifically, with calcium ions – abundant in natural sources of chitin – having the strongest effect on protein stability. When the cation-binding site was rendered non-functional, a decrease in activity was observed, highlighting the importance of the structural elements stabilized by calcium. Our findings suggest a cation-binding site specific to GbpA and related LPMOs that may fine-tune binding and activity for its substrates during environmental survival and host infection.
Evaluation of the Test Phase of the “Program GIFT in Residence”: Results from a Pilot Participatory Action Research
Authors: Falardeau Marie-Chantal , Beaulieu Marie , Carbonneau Hélène , Levasseur Mélanie 
Published: December 2024

Abstract
Despite the negative effects on older adults, resident-to-resident aggression (RRA) remains a complex and understudied problem. Few interventions exist that address this issue by promoting goodwill. Using the intervention mapping approach, the evaluation of the test phase of the pilot Program GIFT in private seniors’ residences (PSRs) (Quebec, Canada) was conducted through qualitative interviews with 25 residents, 21 staff members, and 4 managers. The results indicate that the program achieved its objectives of promoting goodwill, although the strategies to manage RRA and intervention tools were more difficult to integrate into the PSRs’ culture. Obstacles and facilitators were reported. Recommendations were identified to enhance the program’s content, promote it more effectively, and ensure long-term sustainability. This research is the first endeavour to develop, test, and evaluate the test phase of a pilot program co-created with residents, staff members and managers of PSRs, aiming simultaneously at promoting goodwill and countering RRA.
Support for the efficient coding account of visual discomfort
Authors: O’Hare Louise , Hibbard Paul B. 
Published: December 2024

Abstract
Sparse coding theories suggest that the visual brain is optimized to encode natural visual stimuli to minimize metabolic cost. It is thought that images that do not have the same statistical properties as natural images are unable to be coded efficiently and result in visual discomfort. Conversely, artworks are thought to be even more efficiently processed compared to natural images and so are esthetically pleasing. This project investigated visual discomfort in uncomfortable images, natural scenes, and artworks using a combination of low-level image statistical analysis, mathematical modeling, and EEG measures. Results showed that the model response predicted discomfort judgments. Moreover, low-level image statistics including edge predictability predict discomfort judgments, whereas contrast information predicts the steady-state visually evoked potential responses. In conclusion, this study demonstrates that discomfort judgments for a wide set of images can be influenced by contrast and edge information, and can be predicted by our models of low-level vision, whilst neural responses are more defined by contrast-based metrics, when contrast is allowed to vary.
Adults with CHD and their quality of life: a single centre experience from Austria
Authors: Brunner Silvana M. , Oberhuber Raphael D. , Heiligenbrunner Nathalie , Steinwendner Clemens , Wichert-Schmitt Barbara 
Published: December 2024

AbstractBackground:The population of adult CHD patients is continuously increasing. The underlying CHD affects performance and prognosis, but also has a significant impact on quality of life, psychosocial behaviour, anxiety and emotional disturbances. This study analyzes these parameters of patients after one or more heart operations and the possible psychological effects of medical and psychosocial complications at the Department of Cardiology of the Kepler University Hospital Linz.Methods and ResultsA total of 81 subjects participated in the questionnaire survey of the Institute of Cardiology and Clinical Psychology during their annual cardiological check-up. Of these, 80 participants were included in the study and three showed a mild CHD, 49 a moderate one, and 28 a severe one. This study has an exploratory design to assess possible stress factors and limitations in quality of life. For this purpose, a self-administered sociodemographic questionnaire and three standardised questionnaires were used. In summary, the quality of life of adult CHD is considered depending on the severity of the symptoms and compared with the healthy population. Differences in this regard are observed in individuals with lower symptom severity, who report higher psychological well-being. Sex differences are observed in physical role function and physical functioning.Conclusion:Based on the results, regular repetitions of the study, as well as continuous psychological and psychosocial support, are necessary, since challenges are predictable with the increasing age of adult CHD patients and since the upholding of good quality of life and dealing with difficult life circumstances must be supported.
Longitudinal interplay between subjective stress, anxiety, depression, and well-being in internet-based stress recovery intervention for nurses
Authors: Truskauskaite Inga , Dumarkaite Austeja , Nomeikaite Auguste , Andersson Gerhard , Kazlauskas Evaldas 
Published: December 2024

Abstract

Background:
Cognitive behavioural therapy (CBT) interventions are effective in reducing subjective stress. Nevertheless, the longitudinal links between mental health indicators are rarely studied in intervention research. Therefore, it is unknown how the intervention effects are sustained.

Aim:
The current study investigated mechanisms explaining sustained intervention effects in a sample of medical nurses who receive a CBT-based internet-delivered stress recovery program.

Method:
A single-group longitudinal study design with three measurement points, pre-test, post-test, and 3-month follow-up, was used in the current study. The sample consisted of nurses and assistant nurses from Lithuania (n=111, age: M (SD) = 41.69 years (10.85)) who had participated in a 6-week CBT internet intervention targeting stress recovery. Data were collected as the randomised control trial, the treatment samples were combined, and the data were analysed using cross-lagged panel analysis with four variables representing the psychological well-being and symptoms of stress, anxiety, and depression.

Results:
The results revealed that decreased anxiety and increased psychological well-being at post-test predicted reduced stress levels at the 3-month follow-up. In addition, decreased anxiety at post-test predicted decreased depression at follow-up.

Conclusions:
Decreased anxiety and increased well-being could explain the sustainability of reduced stress following a CBT-based internet intervention for nurses. The implications of this for research and practice are discussed.
The cycle of monasticism: understanding the nature of medieval economic and political innovation
Authors: Møller Jørgen 
Published: December 2024

AbstractThis research note develops a new theory about innovation in medieval monastic orders that, first, allows us to better understand medieval society and the nature of its dynamism, and second, can be applied to other areas of research on medieval Europe. Medieval monasteries were set in a society that—despite its famous dynamism—was deeply backward-looking. But monastic life generated antinomies that came from the tension between the degeneration into well-living and the ideal of the asceticism of the first Christians. These tensions sparked repeated attempts to reform monastic life, which were understood by reformers not as innovations but rather as efforts to restore the good old ways. This invention of tradition had economic and political repercussions, first in the monasteries themselves and then in surrounding lay society. To understand these processes, we must avoid reading history backward from a modern context that looks entirely different.
