Duality in the problems of optimal control described by Darboux-type differential inclusions
Authors: Demir Sağlam Sevilay 
Published: January 2024

AbstractThis paper is devoted to the optimization of the Mayer problem with hyperbolic differential inclusions of the Darboux type and duality. We use the discrete approximation method to get sufficient conditions of optimality for the convex problem given by Darboux differential inclusions and the polyhedral problem for a hyperbolic differential inclusion with state constraint. We formulate the adjoint inclusions in the Euler-Lagrange inclusion and Hamiltonian forms. Then, we construct the dual problem to optimal control problem given by Darboux differential inclusions with state constraint and prove so-called duality results. Moreover, we show that each pair of primal and dual problem solutions satisfy duality relations and that the optimal values in the primal convex and dual concave problems are equal. Finally, we establish the dual problem to the polyhedral Darboux problem and provide an example to demonstrate the main constructions of our approach.

Published: January 2024

Abstract
Background
Burnout among providers negatively impacts patient care experiences and safety. Providers at Federally Qualified Health Centers (FQHC) are at high risk for burnout due to high patient volumes; inadequate staffing; and balancing the demands of patients, families, and team members.

Objective
Examine associations of provider burnout with their perspectives on quality improvement (QI), patient experience measurement, clinic culture, and job satisfaction.

Design
We conducted a cross-sectional provider survey about their perspectives including the single-item burnout measure. We fit separate regression models, controlling for provider type, gender, being multilingual, and fixed effects for clinic predicting outcome measures from burnout.

Participants
Seventy-four providers from 44 clinics in large, urban FQHC (52% response rate; n = 174).

Main Measures
Survey included a single-item, self-defined burnout measure adapted from the Physician Worklife Survey, and measures from the RAND AMA Study survey, Heath Tracking Physician survey, TransforMed Clinician and Staff Questionnaire, Physician Worklife Survey, Minimizing Errors Maximizing Outcomes survey, and surveys by Friedberg et al. 31 and Walling et al. 32

Results
Thirty percent of providers reported burnout. Providers in clinics with more facilitative leadership reported not being burned out (compared to those reporting burnout; p-values < 0.05). More pressures related to patient care and lower job satisfaction were associated with burnout (p-values < 0.05).

Conclusions
Creating provider-team relationships and environments where providers have the time and space necessary to discuss changes to improve care, ideas are shared, leadership supports QI, and QI is monitored and discussed were related to not being burned out. Reducing time pressures and improving support needed for providers to address the high-need levels of FQHC patients can also decrease burnout. Such leadership and support to improving care may be a separate protective factor against burnout. Research is needed to further examine which aspects of leadership drive down burnout and increase provider involvement in change efforts and improving care.
A Conservative (R)Evolution? Constitutional–Political Crises, Trumpism, and Long-standing Trends of Conservative Transformations in the United States and Beyond
Authors: Simon Julia , Sonnicksen Jared 
Published: January 2024

AbstractStarting from the most current developments in the legal and political processing of Donald J. Trump’s (post)presidency, this contribution highlights the persisting challenges to the constitutional, social, and political stability of democracy in the United States (U.S.). In particular, it outlines several dimensions of an enabling environment in which Trump(ism) could thrive. A key feature of this is the thorough and ever-growing asymmetry that has come to characterize the partisan political context in the United States and that directs our attention to the conservative side of the political spectrum: the Republican Party as its major organizational embodiment, as well as broader trends of conservative (trans)formation, including those related to the electorate, policies, institutions, civil society, and the media. Thus, this contribution underlines the importance of the multiple and often longer-term influences, conflicts, institutions, and conditions conducive to current developments, including, in particular, the range of actors that have been relevant in shaping them. Asymmetric polarization, economic inequality, and nationalist and anti-government (authoritarian–populist) tendencies and movements are among the factors that together pose the most serious threat to liberal democracy in the United States—and in “the West” more broadly. The introduction illustrates the importance of studying and reflecting upon the implications of the above trends, actors, and conditions for Germany and other European states, for transatlantic cooperation, and even for the global multilateral system as a whole. It concludes with an overview of the research articles in the special issue, outlining their individual as well as overlapping analytical interests and contributions.

Published: January 2024

AbstractUsing knowledge graphs to assist deep learning models in making recommendation decisions has recently been proven to effectively improve the model’s interpretability and accuracy. This paper introduces an end-to-end deep learning model, named representation-enhanced knowledge graph convolutional networks (RKGCN), which dynamically analyses each user’s preferences and makes a recommendation of suitable items. It combines knowledge graphs on both the item side and user side to enrich their representations to maximize the utilization of the abundant information in knowledge graphs. RKGCN is able to offer more personalized and relevant recommendations in three different scenarios. The experimental results show the superior effectiveness of our model over 5 baseline models on three real-world datasets including movies, books, and music.
Aging Mongolian pine plantations face high risks of drought-induced growth decline: evidence from both individual tree and forest stand measurements

Published: January 2024

AbstractDiscerning vulnerability differences among different aged trees to drought-driven growth decline or to mortality is critical to implement age-specific countermeasures for forest management in water-limited areas. An important species for afforestation in dry environments of northern China, Mongolian pine (Pinus sylvestris var. mongolica Litv.) has recently exhibited growth decline and dieback on many sites, particularly pronounced in old-growth plantations. However, changes in response to drought stress by this species with age as well as the underlying mechanisms are poorly understood. In this study, tree-ring data and remotely sensed vegetation data were combined to investigate variations in growth at individual tree and stand scales for young (9 − 13 years) and aging (35 − 52 years) plantations of Mongolian pine in a water-limited area of northern China. A recent decline in tree-ring width in the older plantation also had lower values in satellited-derived normalized difference vegetation indices and normalized difference water indices relative to the younger plantations. In addition, all measured growth-related metrics were strongly correlated with the self-calibrating Palmer drought severity index during the growing season in the older plantation. Sensitivity of growth to drought of the older plantation might be attributed to more severe hydraulic limitations, as reflected by their lower sapwood- and leaf-specific hydraulic conductivities. Our study presents a comprehensive view on changes of growth with age by integrating multiple methods and provides an explanation from the perspective of plant hydraulics for growth decline with age. The results indicate that old-growth Mongolian pine plantations in water-limited environments may face increased growth declines under the context of climate warming and drying.

Published: January 2024

AbstractCytopenia is a common finding in patients admitted to internal medicine wards and the clinical workup may be long and time-consuming. In this single-center observational study, we analyzed a series of 151 inpatients who received hematologist referral due to cytopenia observed during hospital admission. Patients were mainly elderly (median 71 years, 15–96) and 87% had at least one comorbidity. Anemia was the most common cytopenia (91%), followed by thrombocytopenia (51%), and neutropenia (22%); 73 (48%) patients had a bicytopenia and 5 (3%) pancytopenia. Cytopenias were mainly severe, 66% of cases required RBC transfusions, and 21% platelet pools. During a median hospital stay of 15 days (1–166), 53 subjects (35%) received a hematologic discharge diagnosis, whilst the two-thirds had secondary cytopenia mainly due to associated comorbidities. Only about 34% of 2,728 diagnostic tests performed (including laboratory, imaging, and histology) clearly informed the discharge diagnosis in this heterogenous setting. Specifically, bone-marrow evaluation indicated in 46 (30%) patients, was diagnostic in 32 (69.6%). Eleven percent of patients died due to progression of the oncohematologic disease (29%), sepsis (24%), and solid tumor progression (24%). In conclusion, cytopenias in the internal medicine setting are mainly severe, more frequently secondary to associated comorbidities (2/3 of patients) and deserve proper workup before second/third-level tests (immune-hematological assays and CT scan or PET and bone-marrow evaluation, respectively).

Published: January 2024

Abstract
Background
Night shift work leads to severe short- and long-term side effects, posing a risk to personal and occupational safety.

Objective
This study aimed to test the effects of blue-enriched light-emitting glasses on sleepiness, alertness, and sustained attention during the early morning hours of night shift work.

Methods
To remedy the risks of reduced alertness, sustained attention, and increased sleepiness in a single-blind study design, Luminette® 3 (Lucimed SA, Wavre, Belgium) glasses emitting blue-enriched light (BL) were tested from 05:00 to 05:30 during night shift work in 21 participants at a sleep laboratory, and the effects were compared with those of glasses emitting sham dim red light (DRL). Sleepiness was rated hourly from 21:00 to 07:30 using the Karolinska Sleepiness Scale, while alertness was assessed using the PC Psychomotor Vigilance Task before and after the intervention. At the end of the night shift, sustained attention (using the computerized Mackworth Clock Test), comfort ratings, and fatigue were measured. Statistical analyses were conducted using the Friedman and Wilcoxon signed-rank tests.

Results
Sleepiness increased significantly throughout the night and was not significantly reduced after the intervention, with a more prolonged reduction using BL. Compared with using DRL, using BL revealed no clear benefit in terms of alertness or sustained attention, yet comfort ratings were slightly better, without any negative side effects.

Conclusion
In the current study, BL glasses were not clearly superior to DRL glasses in ameliorating the negative side effects of night shift work. Despite some limitations, however, this field study showed high ecological validity and demonstrated the convenient use of an intervention that is easy to implement in a realistic workplace setting.
Treatment of node-positive endometrial cancer: chemotherapy, radiation, immunotherapy, and targeted therapy
Authors: Tubridy Elizabeth A. , Taunk Neil K. , Ko Emily M. 
Published: January 2024

Opinion StatementThe standard of treatment for node-positive endometrial cancer (FIGO Stage IIIC) in North America has been systemic therapy with or without additional external beam radiation therapy (RT) given as pelvic or extended field RT. However, this treatment paradigm is rapidly evolving with improvements in systemic chemotherapy, the emergence of targeted therapies, and improved molecular characterization of these tumors. The biggest question facing providers regarding management of stage IIIC endometrial cancer at this time is: what is the best management strategy to use with regard to combinations of cytotoxic chemotherapy, immunotherapy, other targeted therapeutics, and radiation that will maximize clinical benefit and minimize toxicities for the best patient outcomes? While clinicians await the results of ongoing clinical trials regarding combined immunotherapy/RT as well as management based on molecular classification, we must make decisions regarding the best treatment combinations for our patients. Based on the available literature, we are offering stage IIIC patients without measurable disease postoperatively both adjuvant chemotherapy and IMRT with carboplatin, paclitaxel, and with or without pembrolizumab/dostarlimab as primary adjuvant therapy. Patients with measurable disease post operatively, high risk histologies, or stage IV disease receive chemoimmunotherapy, and vaginal brachytherapy is added for those with uterine risk factors for vaginal recurrence. In the setting of endometrioid EC recurrence more than 6 months after treatment, patients with pelvic nodal and vaginal recurrence are offered IMRT and brachytherapy without chemotherapy. For measurable recurrence not suitable for pelvic radiation alone, chemoimmunotherapy is preferred as standard of care.
Desmoid Tumors: Current Perspective and Treatment
Authors: Mangla Ankit , Agarwal Nikki , Schwartz Gary 
Published: January 2024

Opinion statementDesmoid tumors are rare tumors with a tendency to infiltrate locally. The lack of a standard treatment approach makes choosing the most appropriate treatment for patients challenging. Most experts recommend watchful observation for asymptomatic patients as spontaneous regression of tumor is observed in up to 20% of patients. Upfront resection of the desmoid tumor has fallen out of favor due to high morbidity and high relapse rates associated with the tumor. Systemic therapy has evolved over several decades. Where chemotherapy, hormonal therapy, and non-steroidal anti-inflammatory drugs were used over the last several decades, tyrosine kinase inhibitors came to the forefront within the last decade. Most recently, gamma-secretase inhibitors have shown significant clinical benefit in patients with desmoid tumors, bringing forth an entirely new mechanistic approach. Several Wnt pathway inhibitors are also under development. Invasive approaches like cryoablation have also shown clinical benefit in patients with extra-abdominal desmoid tumors in recent years. The recent approval of nirogacestat has ushered in a new era of treatment for patients diagnosed with desmoid tumors. Several new molecules are expected to be approved over the coming years.
Multiple Origins and Multiple Destinations: The Fertility of Immigrant Women in Europe
Authors: Mussino Eleonora , Cantalini Stefano 
Published: January 2024

AbstractStudies on immigrant fertility typically compare immigrants and natives or different migrant groups at the same destination but rarely immigrants of the same origins in different destination countries. In this paper, we look at immigrants from multiple origins in multiple destination countries simultaneously, using the European Union Labour Force Survey to compare female immigrants from ten areas of origin in eight destination countries in Europe. Our results indicate a strong origin effect. However, they also suggest that when women migrate to a context where the fertility norm is different from that in their origin, they adjust their behaviors accordingly, which indicates that policy and normative context play an important role in shaping migrants’ fertility. From a policy perspective, this is important because it suggests that the fertility of immigrant women, who are exposed to different norms and normative contexts, can resemble that of native women at the destination. Our findings contribute to strengthening the role of destination in shaping fertility behavior and highlighting the importance of looking at all the possible combinations of immigrants coming from and going to different fertility regimes.
Cerebellar Neurostimulation for Boosting Social and Affective Functions: Implications for the Rehabilitation of Hereditary Ataxia Patients

Published: January 2024

AbstractBeyond motor deficits, spinocerebellar ataxia (SCA) patients also suffer cognitive decline and show socio-affective difficulties, negatively impacting on their social functioning. The possibility to modulate cerebello-cerebral networks involved in social cognition through cerebellar neurostimulation has opened up potential therapeutic applications for ameliorating social and affective difficulties. The present review offers an overview of the research on cerebellar neurostimulation for the modulation of socio-affective functions in both healthy individuals and different clinical populations, published in the time period 2000–2022. A total of 25 records reporting either transcranial magnetic stimulation (TMS) or transcranial direct current stimulation (tDCS) studies were found. The investigated clinical populations comprised different pathological conditions, including but not limited to SCA syndromes. The reviewed evidence supports that cerebellar neurostimulation is effective in improving social abilities in healthy individuals and reducing social and affective symptoms in different neurological and psychiatric populations associated with cerebellar damage or with impairments in functions that involve the cerebellum. These findings encourage to further explore the rehabilitative effects of cerebellar neurostimulation on socio-affective deficits experienced by patients with cerebellar abnormalities, as SCA patients. Nevertheless, conclusions remain tentative at this stage due to the heterogeneity characterizing stimulation protocols, study methodologies and patients’ samples.
Enhancing trust in global supply chains: Conceptualizing Digital Product Passports for a low-carbon hydrogen market

Published: January 2024

AbstractIndustries and energy markets around the world are facing mounting pressure to decarbonize, prompting them to transform processes and supply chains towards sustainability. However, a lack of credible sustainability data proves to be a considerable barrier for emerging markets for sustainable products: Against the background of complex and globalized supply chains, it is necessary to verify the sustainability claim of products in order to demand price premiums for sustainable products in the long run. To enable this, it is necessary that stakeholders in globalized supply chains are willing to share relevant data along the entire supply chain for increasing traceability and reducing information asymmetries. Using the example of international hydrogen supply chains, we study how data can be shared between different stakeholders using Digital Product Passports while addressing stakeholders’ concerns about data privacy and disclosure. In our work, we develop design principles that provide insight into how a Digital Product Passport should be designed to verify the hydrogen’s carbon footprint in a reliable way and to ensure the willingness of stakeholders to share their data. We follow a multi-step approach with a structured literature review followed by expert interviews and qualitative content analysis for a synthesis of design principles. Our research illustrates that a Digital Product Passport must collect data comprehensively and automatically, process it in a decentralized and tamper-proof manner, protect privacy and sovereignty of stakeholders, and ensure interoperability.
Working Poor – empirische Einblicke und sozialstaatstheoretische Überlegungen
Authors: Ritter Bettina 
Published: January 2024

ZusammenfassungWorking Poor bezeichnet ein (nicht nur) in Deutschland weit verbreitetes Phänomen: Menschen erzielen zwar durch eigene Erwerbstätigkeit ein Einkommen, welches aber so gering ist, dass sie ihren Lebensunterhalt damit nicht bestreiten können. Eine solche sogenannte Erwerbsarmut ist angesichts ihrer dauerhaften und steigenden Existenz längst zur bundesdeutschen Normalität zu zählen. Der plakative Slogan „Arm trotz Arbeit“, mit dem diese Lebenslage in politischen Debatten problematisiert (Meiser 2022) oder offiziell betitelt wird (Statistisches Bundesamt 2022), drückt demgegenüber aus, dass es sich um eine abzulehnende Abweichung von – zumindest für Westeuropa geltenden – normalen Arbeits- und Lebensverhältnissen handelt, da Arbeit eigentlich vor Armut schützen solle (Pradella 2015). Der vorliegende Beitrag geht dieser Annahme mit Blick auf empirische Realitäten und unter Rückgriff auf sozialstaatstheoretische Perspektiven sowie einige marxistisch-feministische Grundannahmen nach und kommt zu einem kritischen Urteil: Zwar stellt sich die Lage bezüglich der einzelnen arbeitenden und von Armut betroffenen Person als „arm trotz Arbeit“ dar, ihre Armut begründet sich gesamtgesellschaftlich allerdings eher „wegen Arbeit“. Zunächst werden das Phänomen und seine Verbreitung in Deutschland beschrieben und zwei Varianten von Betroffenheit genauer in den Blick genommen: Elternschaft und Behinderung. Anschließend wird dem sozialpolitischen Charakter des Phänomens nachgegangen, bevor daraus ableitend Überlegungen zur gesellschaftskonstituierenden Rolle des Sozialstaats sowie eine gesellschaftstheoretische Begründung von Working Poor umrissen werden. Anschließend werden Implikationen bezüglich sozialer Dienste formuliert, bevor ein Fazit den Beitrag abschließt.
