Interpretation of excess in
H→Zγ
using a light axionlike particle
Authors: Cheung Kingman , Ouseph C. J. 
Published: September 2024

We interpret the recent excess in a rare decay of the Higgs boson, H→Zγ, using a light axionlike particle (ALP) in the mass range 0.05–0.1 GeV. The dominant decay of such a light ALP is into a pair of collimated photons, whose decay is required to happen before reaching the ECAL detector, such that it mimics a single photon in the detector. It can explain the excess with a coupling CaZHeff/Λ∼4×10−5  GeV−1, while the decay of the ALP before reaching the ECAL requires the diphoton coupling Cγγeff/Λ≥0.35  TeV−1(0.1  GeV/ma)2. A potential test would be the rare decay of the Z boson Z→aH*→a(bb¯) at the Tera-Z option of the future FCC and CEPC. However, it has a branching ratio of only O(10−12), and thus barely testable. The production cross section for pp→Z*→aH via the same coupling CaZHeff/Λ at the LHC is too small for detection.

Resonant multiscalar production in the generic complex singlet model in the multi-TeV region
Authors: Lane Samuel D. , Lewis Ian M. , Sullivan Matthew 
Published: September 2024

We develop benchmarks for resonant discalar production in the generic complex singlet scalar extension of the Standard Model (SM) with no additional symmetries, which contains two new scalars. These benchmarks maximize discalar resonant production modes at future pp colliders: pp→h2→h1h1, pp→h2→h1h3, and pp→h2→h3h3, where h1 is the observed SM-like Higgs boson and h2,3 are new scalars. The decays h2→h1h3 and h2→h3h3 may be the only way to discover h3, leading to a discovery of two new scalars at once. Current LHC and projected future collider (HL-LHC, FCC-ee+HL-LHC, ILC500+HL-LHC) constraints on this model are used to produce benchmarks at the HL-LHC for h2 masses between 250 GeV and 1 TeV and a future pp collider (FCC-hh) for h2 masses between 250 GeV and 12 TeV. We update the current LHC bounds on the singlet-Higgs boson mixing angle for these benchmarks. As the mass of h2 approaches the multi-TeV region, certain limiting behaviors of the maximum rates are uncovered due to theoretical constraints on the parameters. These limits, which can be derived analytically, are BR(h2→h1h1)→0.25, BR(h2→h3h3)→0.5, and BR(h2→h1h3)→0. It can also be shown that the maximum rates of pp→h2→h1h1 and pp→h2→h3h3 approach the same value. Hence, all three h2→hihj decays are promising discovery modes for h2 masses at and below O(1  TeV), while above O(1  TeV) the decays h2→h1h1 and h2→h3h3 are more encouraging. We choose benchmark masses for h3 to produce a large range of decay signatures including multi-b, multivector boson, and multi-SM-like Higgs production. As we will show, the behavior of the maximum rates leads to the surprising conclusion that in the multi-TeV region this model may be discovered in the Higgs quartet production mode via h2→h3h3→4h1 decays before Higgs triple production is observed. The maximum di- and four Higgs production rates are similar in the multi-TeV range.

Differentiable and hardware-accelerated waveforms for gravitational wave data analysis
Authors: Edwards Thomas D. P. , Wong Kaze W. K. , Lam Kelvin K. H. , Coogan Adam , Foreman-Mackey Daniel , Isi Maximiliano , Zimmerman Aaron 
Published: September 2024

We propose the use of automatic differentiation through the programming framework for accelerating a variety of analysis tasks throughout gravitational wave (GW) science. Firstly, we demonstrate that complete waveforms which cover the inspiral, merger, and ringdown of binary black holes (i.e., IMRPhenomD) can be written in and demonstrate that the serial evaluation speed of the waveform (and its derivative) is similar to the implementation in . Moreover, allows for graphics processing unit–accelerated waveform calls which can be over an order of magnitude faster than serial evaluation on a CPU. We then focus on three applications where efficient and differentiable waveforms are essential. Firstly, we demonstrate how gradient descent can be used to optimize the ∼200 coefficients that are used to calibrate the waveform model. In particular, we demonstrate that the typical with numerical relativity waveforms can be improved by more than 50%. Secondly, we show that Fisher forecasting calculations can be sped up by ∼3–5× (on a CPU) with no loss in accuracy. This increased speed makes Fisher forecasting for a population of events substantially simpler. Finally, we show that gradient-based samplers like Hamiltonian Monte Carlo lead to significantly reduced autocorrelation values when compared to traditional Monte Carlo methods. Since differentiable waveforms have substantial advantages for a variety of tasks throughout GW science, we propose that waveform developers use to build new waveforms moving forward. Our waveform code, , can be found on GitHub website and will continue to be updated with new waveforms as they are implemented.

Published: September 2024

PurposeOnline learning is increasingly popular, and educational platforms provide a wealth of courses. Improving course sales is the key to promoting sustainable development of online course platforms. However, limited research has explored the marketing of online courses. We study how to drive online course sales by leveraging teacher information.Design/methodology/approachWe performed an empirical study. We collected data through a crawler and image recognition from Tencent classroom.FindingsOur results show that providing teacher information and profile images helps promote online course sales. However, detailed course descriptions weaken the positive impact of teachers' profile images on online course sales. Furthermore, our study shows an inverted U-shaped relationship between the intensity of smiling in teacher profile photos and online course sales, and teacher descriptions negatively moderate this relationship.Research limitations/implicationsOur study contributes to the research on online course sales and extends the context of the research on smiling as well as the studies of visual and textual information.Practical implicationsThe results have practical implications for online course sellers and platforms.Originality/valueExisting scholarly efforts have explored online courses mainly from an education perspective. More research is needed to advance the understanding of online course sales. Our study advances research in the marketing of online courses.

Internal control effectiveness, supply chain management efficiency and capital allocation efficiency: evidence from the COVID-19 pandemic
Authors: Arianpoor Arash , Valirouh Milad , Sahin Cumhur 
Published: September 2024

PurposeThe present study aims to investigate the impact of internal control effectiveness on supply chain management efficiency (SCME) and capital allocation efficiency for companies listed in the Tehran Stock Exchange (TSE). In addition, it investigates the mediating role of supply chain management efficiency in the relationship between internal controls and capital allocation efficiency.Design/methodology/approachThe data about 191 companies in 2014–2022 were examined. The sales per inventory ratio was used to calculate SCME. The present study also applied the Generalized Method of Moments (GMM) for endogeneity concerns.FindingsThe results showed that internal control effectiveness has a significant positive effect on SCME. Moreover, internal control effectiveness and SCME significantly positively affect capital allocation efficiency. SCME has a mediating role in the relationship between internal control effectiveness and capital allocation efficiency. These findings remained robust even after several robustness tests. In addition, this study tested the results' robustness by dividing data into the pre-COVID-19 and post-COVID-19 years. The previous results were also confirmed according to the robustness test of COVID-19.Originality/valueChallenges in the supply chain often hinder capital allocation efficiency. In addition, enterprises should try to establish strong internal controls to ensure SCME. Therefore, the relationship between internal control effectiveness, SCME and capital allocation efficiency is complex and underscores the importance of robust internal controls in optimizing resource allocation within organizations. Interestingly, this topic has not been extensively researched in accounting and business research, and there is a lack of empirical evidence on these effects. Consequently, this study aims to fill the gap and identify potential opportunities for new research directions.
Bibliographical foundations of information science: a review essay
Authors: Hjørland Birger 
Published: September 2024

PurposeThe narrow purpose of this article is to review de Fremery’s (2024) book about the bibliographic foundations of information science. The broader purpose is to consider the actual as well as the potential relevance of the field(s) of bibliography for information science besides the book under review.Design/methodology/approachThis review essay examines the arguments put forward by de Fremery (2024), introduces concepts and traditional lore from the study of bibliography and presents internal conflicts or paradigms in the field of bibliography. It relates this information to foundational issues in information science.FindingsDe Fremery’s basic ambition of basing information science in the field of bibliography is important, and so is the attempt to consider bibliography in relation to contemporary information technologies such as machine learning and data science. The book under review fails, however, to describe the relations between different positions in bibliography, such as enumerative, analytical, descriptive, critical and historical bibliography in relation to information science. It rather tends to make problematic claims, for example, that scientific experiments are based on bibliographical methods, and to describe the relation of bibliography to information science on the basis of such interpretations. Nonetheless, the book is a serious attempt to consider the field of bibliography and thereby support the focus on documents in information science.Originality/valueInformation science often suffers because of ambiguities in the concept of information. When information science is understood as the study of literature-based answering, much else falls into place. The field of bibliography is a core concept for this understanding and re-orientation of information science, for example, by establishing the core relation between bibliography, information searching and knowledge organization.
Incubating innovation: the role of incubators in supporting business model innovation
Authors: Braun Sjard , Suoranta Mari 
Published: September 2024

Purpose
The role of incubators in promoting startup growth has received close research attention, but the findings paint a conflicting picture. This study aims to reduce the ambiguity surrounding incubator impact by exploring how incubators can support startups with business model innovations – a significant growth factor for startups neglected in the incubation literature.

Design/methodology/approach
Using a multiple-case study design, the authors conducted semistructured interviews with incubator directors and startup founders, offering insights into their experiences. The transcripts were coded following the Gioia method.

Findings
This study shows that incubatees are exposed to and struggle with business model innovation. Therefore, this study explores how incubators can support startups in innovating their business models.

Research limitations/implications
This research reveals the importance of addressing the psychological needs of entrepreneurs in incubators. By offering emotional support, incubators can create a positive psychological environment, helping entrepreneurs face fears and challenges. This highlights the human side of entrepreneurship, which has not been considered in the incubation literature.

Practical implications
Incubator directors can strengthen their programmes’ impact by offering tailored support for business model innovation and facilitating network connections. Policymakers should encourage ecosystem collaboration and allocate resources to effective programmes.

Originality/value
This research fills a gap in the incubation literature by emphasizing the significance and need for support for business model innovation. This study also offers original insights into the psychological dimensions of entrepreneurship.
Development of a novel system for measuring femoroacetabular contact forces in hip arthroscopy
Authors: Gonçalves Sérgio B , Dantas Pedro , Guedes de Melo Francisco , Gouveia João , Guimarães Consciência José , Martins Jorge , Silva Miguel Tavares da 
Published: September 2024

Purpose
Arthroscopic osteochondroplasty is a minimally invasive procedure that has been used to treat femoroacetabular impingement syndrome, leading to significant improvements in patients’ clinical outcomes and quality of life. However, some studies suggest that inadequate bone resection can substantially alter hip biomechanics. These modifications may generate different contact profiles and higher contact forces, increasing the risk of developing premature joint degeneration. To improve control over bone resection and biomechanical outcomes during arthroscopic osteochondroplasty surgery, this study aims to present a novel system for measuring femoroacetabular contact forces.

Design/methodology/approach
Following a structured design process for the development of medical devices, the steps required for its production using additive manufacturing with material extrusion and easily accessible sensors are described. The system comprises two main devices, one for measuring femoroacetabular contact forces and the other for quantifying the force applied by the assistant surgeon during lower limb manipulation. The hip device was designed for use within an arthroscopic environment, eliminating the need for additional portals.

Findings
To evaluate its performance, the system was first tested in a laboratory setup and later under in-service conditions. The 3D printing parameters were tuned to ensure the watertighness of the device and sustain the intraoperative fluid pressures. The final prototype allowed for the controlled measurement of the hip contact forces in real-time.

Originality/value
Using additive manufacturing and readily available sensors, the present work presents the first device to quantify joint contact forces during arthroscopic surgeries, serving as an additional tool to support the surgeon’s decision-making process regarding bone resection.
Cattle exclusion increases encounters of wild herbivores in Neotropical forests

Published: September 2024

Abstract

Ongoing habitat loss and species extinctions require managers to implement and quantify the effectiveness of conservation actions for protecting biodiversity. Fencing, when done properly, is an important management tool for conservation in landscapes where wildlife and domestic animals co‐occur, potentially enhancing habitat use through selective exclusion of domestic species. For instance, the fencing of forest patches in the Neotropics is expected to reduce the degradation of understory vegetation by cattle, releasing these resources for the native community of browsers and fruit consumers.

Here, we implemented an ecological experiment using a before‐after control‐impact design to quantify the effect of cattle exclusion on encounter probability of the native community of browsers and fruit consumers, and percent ground cover in multifunctional landscapes of the Colombian Orinoquía. We built 14 km of wildlife‐permeable fences along forest edges in four forest patches (i.e. blocks) containing control and fenced (treatment) sites. We installed 33 camera traps to obtain information about wildlife and cattle encounter probabilities, before and after the fences were constructed. We used Bayesian generalised linear mixed effects models to quantify the effect of fences via the interaction between the time period (before and after the fences were built) and treatment (control or fenced sites).

Fencing was effective at reducing encounter probabilities of cattle in the treated sites, and it had a positive impact on relative encounter probabilities of four of seven studied wildlife species (herbivores including the black agouti [dry season only], lowland tapir [dry season only] and spotted paca [both seasons] and an omnivore, the South American coati [rainy season only]). The effect of fencing was negative for the collared peccary but only during the dry season. No statistically significant effect was detected for the white‐lipped peccary or white‐tailed deer.

Synthesis and applications: We provide experimental evidence that fences are effective at selectively excluding cattle and increasing encounter rates of wild browsers and fruit consumers in forest patches where these species co‐occur with cattle. Our results highlight an important application of fencing ecology in Neotropical forests, where the implementation of wildlife‐permeable fences is feasible due to smaller body sizes of wildlife compared to domestic animals such as cattle.

Othering and ethics of belonging in migrants' embodied healthcare experiences
Authors: Subramani Supriya 
Published: September 2024

AbstractAt a time when national identities are being reasserted in Western Europe alongside moral and intellectual visions of a cosmopolitan order more inclusive than nationalism, what does belonging mean for immigrants who are non‐Europeans, particularly for women from South Asia, Africa and the Middle East? Based on the lived experiences of 23 women of diverse backgrounds, who are first‐generation immigrants, regarding their experiences while accessing the healthcare system in Zurich, Switzerland, I illustrate through migrant experiences how Othering and belonging are experienced within the web of chaotic meanings and social space one navigates. By employing a phenomenological–sociological approach, I present how embodied migrant experiences can capture the experiences of being an 'Other', as well as how moral emotions such as shame and humiliation can influence one's moral self and its significance to everyday moral discourse. While much of the academic discourse around belonging focuses on a place and its related connectedness to one's racial, gender and ethnic identity, here, I analyse cosmopolitanism's possibilities through Othering/belonging experiences within the healthcare context, and beyond. I conclude this paper with the key contributions of the ethics of belonging to the normative discourse on migration health.
The economic roots of cross‐national similarity in voter preferences
Authors: Fortunato David , Juhl Sebastian , Williams Laron K. 
Published: September 2024

AbstractWe argue that economic and political integration leads voters' political preferences toward cross‐national convergence. Analyzing data on voter preferences across 30 European democracies from 1976 to 2022, we measure the similarity of preference distributions across state dyads over time, documenting an average increase in similarity over this period. We then model these associations statistically and find that greater similarity and complementarity in economic production and co‐participation in the European Union and the Eurozone are associated with increasingly similar voter preferences. The argument and analyses broaden our understanding of the political implications of globalization and also provide a theoretical and empirical foundation for two growing literatures: one on the cross‐national diffusion of parties' strategies and one on the political implications of macroeconomic stimuli such as trade shocks or banking crises.
Barriers for bariatric surgery in provincial New Zealand: a qualitative analysis

Published: September 2024

AbstractBackgroundBariatric surgery is the most effective treatment for people with obesity. It has been shown that there's is a complex psychosocial overlay in the pathophysiology and treatment, which requires specific consideration when delivering care. There is a significant drop out rate for patients accepted on to bariatric programmes in New Zealand, resulting in failure to progress to surgical intervention.MethodsWe conducted individual, semi‐structured interviews with patients who were accepted onto the bariatric surgery programme but did not complete the programme, or receive an operation between 2015 and 2020. Grounded theory methodology was used to create an exploratory framework to identify and describe the themes encountered. An iterative process of thematic analysis and comparison between participants experiences was used to consolidate the shared key barriers. This study aims to explore patients experiences of a bariatric surgery programme to understand barriers and enablers to complete a bariatric programme and receive an operation. Adding to previous qualitative work investigating patients experience of bariatric surgery programmes in New Zealand.ResultsFive themes of barriers that patients face to receiving bariatric surgery were identified. These were preoperative weight loss requirement, experiencing the social stigma of obesity, communication, socioeconomic and geographic barriers, and community support. These five themes often co‐exist in patients experiences and combine, to cause patients to disengage with the bariatric service.ConclusionMany factors contribute to eligible patients not receiving bariatric surgery once accepted onto the programme. Specified weight loss goals was the most significant barrier. Community support and online resources were significant enablers. This study should inform changes to bariatric programmes in New Zealand.
