Sequential parametrized topological complexity of sphere bundles
Authors: Farber Michael , Paul Amit Kumar 
Published: September 2024

AbstractAutonomous motion of a system (robot) is controlled by a motion planning algorithm. A sequential parametrized motion planning algorithm [10] works under variable external conditions and generates continuous motions of the system to attain the prescribed sequence of states at prescribed moments of time. Topological complexity of such algorithms measures their structure and discontinuities. Information about states of the system consistent with states of the external conditions is described by a fibration $$p:E\rightarrow B$$

Quiet Quitting as Compensatory Respect: Meaningful Work, Recognition, and the Entrepreneurial Ethic
Authors: Corbin Thomas A. , Flenady Gene 
Published: September 2024

AbstractThis paper employs Axel Honneth’s recognition theory to interpret ‘quiet quitting’ – the practice of limiting work efforts to contracted requirements – as a strategic response by workers facing misrecognition in their work environment. Honneth argues that misrecognition in any one of three social spheres (the family, political society, and the workplace) constitutes disrespect and causes psychological harm. While Honneth contends that experiences of disrespect tend to motivate collective “struggles for recognition,” we suggest that quiet quitters present an alternative response to disrespect, individually seeking recognition in other social spheres rather than engaging in collective action. Further, we draw on Honneth to suggest that the contemporary “entrepreneurial” work ethic – the widespread expectation that workers invest emotionally in their work role – can in practice undermine workplace recognition, contributing to quiet quitters’ compensatory emphasis on recognitive relations outside of work. This recognition-theoretical approach extends current discussions around quiet quitting and yields valuable insights for management theory and practice regarding the critical role of genuine employee recognition in promoting individual well-being and meaningful work experiences.
Elucidating the effects of metal transfer modes and investigating the material properties in wire-arc additive manufacturing (WAAM)
Authors: Iqbal Hambal , Ascari Alessandro , Fortunato Alessandro , Liverani Erica 
Published: September 2024

AbstractStudies have shown the influence of WAAM process parameters on mechanical properties, bead formation, dimensional accuracy, and microstructure. However, metal transfer modes and their interactions with input variables have not been investigated thoroughly. Therefore, short/spray, pulse and double pulse modes were investigated in this study at different current levels. Bead-on-plate trials were conducted by depositing ER70S-6 wire to investigate bead morphology, dilution, microstructure, and hardness. The study was supported by a detailed statistical approach, including analysis of variance (ANOVA) and regression analysis. Similarly, the combined effects of hatch distance and current were studied on bead formation in multi-layer deposits. Moreover, a thin wall and a cubic structure were deposited to realize the WAAM capability for larger depositions. The microstructures of thin wall and cubic structure were analyzed using optical microscopy (OM) and scanning electron microscopy (SEM). The study concludes that metal transfer modes at various currents significantly influence bead geometry, microstructure and hardness. The microstructure of bead-on-plate trials show fine lamellar structure at low current in all modes. Higher current results in coarse grains with a polygonal and columnar morphology. The hardness shows a decreasing trend as the current increases. The combined effects of current and hatch distance alter bead morphology; however, an optimized combination yields smoother surfaces. The microstructure of thin wall showed a slight anisotropy along the building direction. The presence of small pores was witnessed from OM and SEM images. Similarly, the cubic structure showed a more homogeneous microstructure with much lower porosity. The hardness profile of the thin wall exhibited small fluctuations along the building direction, while that of the cubic structure was more uniform.
Experiencing Meaningful Work through Corporate Volunteering: The Other as a Source of Meaning
Authors: Hatami Akram , Glińska-Neweś Aldona , Hermes Jan 
Published: September 2024

AbstractGlobal social, ecological and economic crises are contributing to the need for meaningfulness in different spheres of life, including work, as an increasing concern to employees. However, the current understanding of meaningfulness is bound by its normativity and thus does not meet the uncertainty present in today’s work. We utilize the Levinasian concept of “the Other” to provide a non-normative conceptualization of meaningfulness in the context of corporate volunteering (CV) and empirically explore work meaningfulness in CV projects in Poland and Finland. We find work meaningfulness to arise from proximity to the Other and the otherness of the Other. Our study contributes to the discussion on meaningful work in the fields of business ethics and management studies through a non-normative reconceptualization of meaningfulness.
A Methodology to Measure Glucose Metabolism by Quantitative Analysis of PET Images

Published: September 2024

AbstractPositron emission tomography (PET) with F-18 fluorodeoxyglucose (FDG) tracer is the standard clinical technique to measure myocardial and vessel metabolism and viability and to investigate the metabolic syndrome associated with cardiovascular diseases. The quantitative analysis of PET images allows one to study the cardiovascular physiological processes, by extracting quantitative parameters from the analysis of the tracer kinetic. Here, we propose a new methodology to quantify and evaluate the evolution of glucose metabolism inside the myocardium and the large vascular structures over time. We merge and analyze PET and CT cardiac images, extracting different volumes of interest (VOI) and performing quantitative measurements. To validate it, we apply the methodology to merge images of the aorta vessel for patients affected by metabolic syndrome. The application of the proposed approach to the use case reveals a correlation between administered drugs and metabolic syndrome, measuring the glucose metabolic rate (MRGlu) in both the myocardium and aorta. The proposed methodology can be used to evaluate some cardiovascular risk indexes of diabetic patients, too. The proposed methodology can also be deployed to analyze other application domains.

Published: September 2024

Abstract

Purpose
This study aims to provide an overview of different deep learning algorithms (DLAs), identify the limitations, and summarize potential solutions to improve the performance of DLAs.

Methods
We reviewed eligible studies on DLAs for automated Cobb angle estimation on X-rays and conducted a meta-analysis. A systematic literature search was conducted in six databases up until September 2023. Our meta-analysis included an evaluation of reported circular mean absolute error (CMAE) from the studies, as well as a subgroup analysis of implementation strategies. Risk of bias was assessed using the revised Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2). This study was registered in PROSPERO prior to initiation (CRD42023403057).

Results
We identified 120 articles from our systematic search (n = 3022), eventually including 50 studies in the systematic review and 17 studies in the meta-analysis. The overall estimate for CMAE was 2.99 (95% CI 2.61–3.38), with high heterogeneity (94%, p < 0.01). Segmentation-based methods showed greater accuracy (p < 0.01), with a CMAE of 2.40 (95% CI 1.85–2.95), compared to landmark-based methods, which had a CMAE of 3.31 (95% CI 2.89–3.72).

Conclusions
According to our limited meta-analysis results, DLAs have shown relatively high accuracy for automated Cobb angle measurement. In terms of CMAE, segmentation-based methods may perform better than landmark-based methods. We also summarized potential ways to improve model design in future studies. It is important to follow quality guidelines when reporting on DLAs.
The role of the cryosphere for runoff in a highly glacierised alpine catchment, an approach with a coupled model and in situ data
Authors: Lambrecht Astrid , Mayer Christoph 
Published: September 2024

Abstract
Runoff from heavily glacierised catchments, its seasonality and the contribution from different storage units are highly relevant for assessing the seasonal and long-term water supply and flood prediction. Modelling studies on runoff from such basins often use simulated meteorological input (e.g. downscaling products) based on remote observations. We investigate the contribution of snow, firn and ice to runoff in the Vernagtferner basin (Ötztal Alps) from 2020 to 2022, using a physical modelling chain driven by a local observation network. We use the SNOWPACK model to simulate snow/ice development at observation sites and the Alpine3D model to calculate accumulation and melt at the catchment scale. Basin discharge is estimated using a gridded version of the HBV-ETH model. This approach largely reproduces observed glacier mass balances, while modelled and measured basin discharge are in good agreement. Snowmelt dominates discharge in the early melt season, while ice melt becomes increasingly important during summer. This is in strong contrast to the near-equilibrium mass balances in the 1980s, when ice melt played a minor role for annual discharge. The strong reduction of the accumulation area leads to a fundamental change from a snowmelt regime to an ice melt regime, which is especially pronounced in 2022.
Dynamics of Intermarriage in Europe
Authors: Lendák-Kabók Karolina , Örkény Antal 
Published: September 2024

AbstractThis article analyses the scholarly results concerning the social phenomenon of intermarriage. It specifically focuses on the similarities and differences in the latter in Europe, between migrants and host society members, and between national minorities and majorities. The study shows that while intermarriage between migrants and host society members is often seen as a vehicle for bridging social gaps and promoting social cohesion, intermarriages between national minorities and majorities is more likely to lead to erosion of minority identities and cultural traits. Common challenges faced by intermarried couples include resistance from family members and bureaucratic obstacles, with gender dynamics playing a crucial role, particularly in traditional societies where women often bear the brunt of cultural assimilation. Intermarriage also promotes the perspective of the integrative nature of nation-states without requiring intervention by the states themselves. The article underscores the importance of deepening the discourse on intermarriage and focusing on the impact of the latter on both migrant and national minority communities through both quantitative analyses and qualitative approaches. This may improve the understanding of the transformative potential and challenges of these unions.
Slovak National Communism in Interwar Czechoslovakia
Authors: Benko Juraj , Hudek Adam 
Published: September 2024

Abstract
Slovak national communism as a specific approach to the problem of Czech-Slovak relations gained a significant position within the Communist Party of Czechoslovakia soon after its establishment in 1921. This article analyzes the foundations of this phenomenon and the evolving attitudes of the first generation of Slovak communist intellectuals and Party functionaries. The article’s primary focus is on the Slovak communists’ views regarding the official state doctrine of a unified Czechoslovak nation, Czech-Slovak relations, and the issue of Slovak autonomy. The study highlights the significant external influences, particularly the directives of the Communist International and the pre-existing national stereotypes, that shaped the worldview and nationalist tendencies of Slovak communists.

Published: September 2024

AbstractAdopting policies that promote health for the entire biosphere (One Health) requires human societies to transition towards a more sustainable food supply as well as to deepen the understanding of the metabolic and health effects of evolving food habits. At the same time, life sciences are experiencing rapid and groundbreaking technological developments, in particular in laboratory analytics and biocomputing, placing nutrition research in an unprecedented position to produce knowledge that can be translated into practice in line with One Health policies. In this dynamic context, nutrition research needs to be strategically organised to respond to these societal expectations. One key element of this strategy is to integrate precision nutrition into epidemiological research. This position article therefore reviews the recent developments in nutrition research and proposes how they could be integrated into cohort studies, with a focus on the Swiss research landscape specifically.
Parasitic behaviour and developmental morphology of Anastatus japonicus reared on the factitious host Antheraea pernyi

Published: September 2024

AbstractThe egg parasitoid Anastatus japonicus is a key natural enemy in the biological control of various agricultural and forestry pests. It is particularly used against the brown marmorated stink bug Halyomorpha halys and the emerging defoliator pest Caligula japonica in East Asia. It has been proved that the eggs of Antheraea pernyi can be used as a factitious host for the mass production of A. japonicus. This study systematically documented the parasitic behaviour and developmental morphology exhibited by A. japonicus on the eggs of A. pernyi. The parasitic behaviour of A. japonicus encompassed ten steps including searching, antennation, locating, digging, probing, detecting, oviposition, host-feeding, grooming, and resting. Oviposition, in particular, was observed to occur in three stages, with the parasitoids releasing eggs during the second stage when the body remained relatively static. Among all the steps of parasitic behaviour, probing accounted for the longest time, constituting 33.1% of the whole time. It was followed by digging (19.3%), oviposition (18.5%), antennation (9.6%), detecting (7.4%), and the remaining steps, each occupying less than 5.0% of the total event time. The pre-emergence of adult A. japonicus involves four stages: egg (0 to 2nd day), larva (3rd to 9th day), pre-pupa (10th to 13th day), pupa (14th to 22nd day), and subsequent development into an adult. Typically, it takes 25.60 ± 0.30 days to develop from an egg to an adult at 25℃. This information increases the understanding of the biology of A. japonicus and may provide a reference for optimising reproductive devices.
Negotiating power: Disputes over electrification in rural India
Authors: Roy Indrajit 
Published: September 2024

AbstractHow are infrastructures socially appropriated? This article uses my fortuitous presence in a rural locality in eastern India as its residents discussed proposals for its complete electrification, allowing me to reflect on social negotiations around infrastructure prior to its installation. Drawing on a detailed ethnography of electrification in a West Bengal village, I illustrate the nuanced ways in which people inflect infrastructural projects with their collective ideas of what is right and good. As far as they can see, such projects are neither the unalloyed benefit that proponents celebrate nor the unmitigated evil that opponents lament. Rather, they are evaluated in relation to people’s imagination of the collective good, to which such infrastructures may or may not be central. Drawing on the insights offered by my interlocutors as well as recent advances in the literature on the politics of infrastructures, this article interrogates the perspective that infrastructures advance governmental rationalities. Building on well-established insights that technological infrastructures are not socially neutral and that infrastructures are socially appropriated, disputed, and negotiated, this article demonstrates that people’s engagement with infrastructures politicizes, rather than governmentalizes, them.
Large-bodied gastric spirurids (Nematoda, Spirurida) predict structure in the downstream gastrointestinal helminth community of wild spiny mice (Acomys dimidiatus)
Authors: Behnke Jerzy M. , Jackson Joseph A. , Gilbert Francis , Mohallal Eman M. E. , Bajer Anna 
Published: September 2024

AbstractThe dominant helminths infecting spiny mice (Acomys dimidiatus) in the montane wadis of the Sinai Peninsula of Egypt are spirurid nematodes, notably Protospirura muricola and Mastophorus muris. Both are relatively large robust stomach worms that accumulate in hosts resulting in high worm burdens. To ascertain whether the presence of spirurid worms or their burdens alters the host's likelihood of infection with other helminth species, we analysed a database containing quantitative data on helminth parasites of these mice (n = 431). This comprised of worm burdens recorded during 4 surveys, conducted at 4-year intervals, in 4 wadis, during late summer of each year. The presence of spirurid worms did not significantly alter species richness with other helminth species nor the likelihood of mice carrying other nematode species. However, there was a significant association, particularly of P. muricola, with the presence of intestinal stages of cestodes, and with the acanthocephalan Moniliformis acomysi. After controlling for intrinsic and extrinsic factors, mice harbouring spirurid worms had greater worm burdens of other helminths compared with mice without spirurids. Moreover, spirurid worm burdens showed a significant positive covariation with similarly adjusted species richness of other helminths, non-spirurid helminths, non-spirurid nematodes, oxyuroid nematodes and intestinal stage cestode worm burdens. We interpret these results as an indication that the key driver for co-occurrence of spirurids with other helminths is likely to be transmission via common arthropod hosts (for cestodes and acanthocephalans), but also that mice carrying the heavier spirurid worm burdens become more susceptible to directly transmitted nematodes such as the Oxyuroidea.

AbstractBackgroundWhile previous studies have reported high rates of documented suicide attempts (SAs) in the U.S. Army, the extent to which soldiers make SAs that are not identified in the healthcare system is unknown. Understanding undetected suicidal behavior is important in broadening prevention and intervention efforts.MethodsRepresentative survey of U.S. Regular Army enlisted soldiers (n = 24 475). Reported SAs during service were compared with SAs documented in administrative medical records. Logistic regression analyses examined sociodemographic characteristics differentiating soldiers with an undetected SA v. documented SA. Among those with an undetected SA, chi-square tests examined characteristics associated with receiving a mental health diagnosis (MH-Dx) prior to SA. Discrete-time survival analysis estimated risk of undetected SA by time in service.ResultsPrevalence of undetected SA (unweighted n = 259) was 1.3%. Annual incidence was 255.6 per 100 000 soldiers, suggesting one in three SAs are undetected. In multivariable analysis, rank ⩾E5 (OR = 3.1[95%CI 1.6–5.7]) was associated with increased odds of undetected v. documented SA. Females were more likely to have a MH-Dx prior to their undetected SA (Rao-Scott χ21 = 6.1, p = .01). Over one-fifth of undetected SAs resulted in at least moderate injury. Risk of undetected SA was greater during the first four years of service.ConclusionsFindings suggest that substantially more soldiers make SAs than indicated by estimates based on documented attempts. A sizable minority of undetected SAs result in significant injury. Soldiers reporting an undetected SA tend to be higher ranking than those with documented SAs. Undetected SAs require additional approaches to identifying individuals at risk.
When and how patients' self-claims are challenged in psychotherapy
Authors: Peräkylä Anssi , Voutilainen Liisa , Wuolio Mariel , Deppermann Arnulf 
Published: September 2024

Abstract
The article describes the practices through which patients’ self-presentations are challenged in psychotherapy. Based on the analysis of thirty-eight instances from psychodynamic psychotherapy and psychoanalysis, analyzed with methods of conversation analysis, narrative analysis, and coding, this article reports on how therapists challenge patients’ self-conceptualizations in response to patients’ self-presentations. Challenges mostly follow patients’ descriptive, narrative, or evaluative accounts that include a strong claim about their self. Challenges to the self pertain to core issues of the therapeutic projects. They are mostly built in ways that show its sensitivity to probable rejection by the patient. Overwhelmingly, the challenge is accounted for by reference to shared knowledge built in the participants’ shared interactional history. Arguably, psychotherapy is a particular setting where the organization of face-work is modified, as occasional challenging of the co-interactant's self-presentation is part of the institutional task of the professional participant. Data are in Finnish and German. (Self, psychotherapy, Goffman, conversation analysis)*
