Approximating the Pareto frontier for bi-objective preventive maintenance and workshop scheduling: A Lagrangean lower bounding methodology for evaluating contracting forms
Authors: Obradović Gabrijela , Strömberg Ann-Brith , Held Felix , Lundberg Kristian 
Published: November 2024

AbstractEffective planning of preventive maintenance plays an important role in maximizing the operational readiness of any industrial system. We consider an operating system and a maintenance workshop governed by two stakeholders who collaborate based on a mutual contract: components of the operating system that need maintenance are sent to the maintenance workshop, where necessary maintenance activities are performed and after which the maintained components are returned to the operating systems and ready to be used again. While the maintenance activities must obey the workshop capacity, the components should be returned to the operating system within a contracted time frame. For this problem, we developed in a previous work a mixed-integer linear optimization model incorporating stocks of damaged as well as repaired components, workshop scheduling, and preventive maintenance planning for the operating system. We then investigated an availability contract between the stakeholders and which is in the paper at hand compared with a turn-around time contract type, which is more often used in reality. Since, for real instance sizes, the latter leads to a computationally demanding bi-objective optimization problem, we use Lagrangean relaxation and subgradient optimization to compute local lower bounds on the set of non-dominated points, complemented with math-heuristics to identify good feasible solutions (i.e., local upper bounds). Our suggested method thus provides a bounding of the set of non-dominated points for a turn–around time contract.

Published: November 2024

AbstractResting heart rate variability (HRV) is typically higher in those with better emotional well-being. In the current study, we examined whether changes in resting HRV mediated changes in negative emotions during a 7-week clinical trial of HRV biofeedback. Younger and older adults were randomly assigned to one of two daily biofeedback practices for 5 weeks: (1) engage in slow-paced breathing to increase the amplitude of oscillations in heart rate at their breathing frequency (Osc+); or (2) engage in self-selected strategies to decrease heart rate oscillations (Osc−). We assessed negative emotion using the State Anxiety Inventory (SAI) and Profile of Mood States (POMS). Resting HRV at pre-intervention was significantly higher among those with lower negative emotion scores. Those participants showing greater increases in resting HRV showed greater decreases in negative emotion. In a mediation model with all participants, resting HRV changes significantly mediated the relationship between training performance (i.e., heart rate oscillation during practice sessions) and changes in negative emotion. However, additional analyses revealed this mediation effect was significantly moderated by condition and was only significant in the Osc+ condition. Thus, resting HRV changes mediated how biofeedback to increase amplitude of heart rate oscillations reduced negative emotion.
The Social Representations of Pornography Consumers Among Individuals in Romantic Relationships: Exploring the Roles of Gender, Relationship Satisfaction, and Sexual Satisfaction in a Romanian Sample

Published: November 2024

Abstract
Understanding the psychological conflicts associated with pornography consumption can help professionals tailor their interventions to address the mental health risks faced by individuals struggling with issues related to their pornography use. The main objective of this research was to investigate how pornography consumers are perceived from a social representation theoretical perspective and to examine variations in these perceptions—or social representations—according to gender, relationship satisfaction, and sexual satisfaction. All participants (N = 875 Romanians) were in a romantic relationship at the time of participation. Our results indicated that the social representation of pornography consumers varied significantly depending on gender, sexual satisfaction, and relationship satisfaction. Also, our findings showed a potential psychological conflict in the long run, which can put individuals at risk for self-stigma, guilt, and subsequent mental health consequences. We discuss conclusions from both a theoretical and practical perspective, with a focus on the utility of our conclusions in the clinical practice context of psychologists, psychotherapists, and mental health workers when dealing with issues related to pornography use.

Abstract
Purpose
Research on disparities in prognosis and clinical characteristics between public and private healthcare sectors in developing countries remains limited. The study aimed to determine whether patients with public health coverage (1) have a greater mean tumor size at diagnosis compared to those with private health coverage; (2) exhibit differences in clinical staging and TNM classification between groups; and (3) show variations in demographic, clinical characteristics, histopathological findings, and surgical approaches among cohorts.

Methods
A cross-sectional, multicenter study was conducted on 629 patients from both private and public healthcare sectors, all histologically confirmed and surgically treated for Renal Cell Carcinoma (RCC), between 2011 and 2021 in high-volume hospitals in Monterrey, Mexico. To compare variables between groups, we employed independent samples t-tests, Mann Whitney U nonparametric test, along with Pearson’s chi-square test complemented by post hoc analyses.

Results
Mean tumor size in the public group was 1.9 cm greater than in the private group (7.39 vs. 5.51 cm, p < 0.001). Patients in the public sector more frequently presented with larger tumors, a higher prevalence of risk factors (excluding BMI and hypertension), advanced disease (OR 2.12, 95% CI 1.43–3.16, p < 0.001), presence of symptoms, elevated TNM, lymphovascular invasion and a lower prevalence of minimally invasive surgery. A male-to-female ratio of 2.6:1 was noted in the private coverage group.

Conclusions
This study highlights a notable association between public health coverage and a higher prevalence of advanced RCC, with tumors in private coverage patients being smaller yet larger than commonly reported. There is a crucial need to develop new health policies for early detection of renal cancer in developing countries.

Published: November 2024

AbstractThe writing process approach is recognized as an effective instructional practice for engaging children in the writing process and developing emerging writing skills. The writing conference is an integral component of the writing process. One-on-one conferencing sessions create differentiated instructional spaces for teachers to respond to the individual needs of learners. Understanding how teachers leverage conferencing sessions to effectively engage and support young learners’ writing remains a limited area of research. This case study documents one experienced teacher’s conferencing practices with 19 first-grade writers. Findings show conferencing conversations worked in an integrated, multidimensional way to support young writers. Conferencing dimensions leveraged children’s funds of knowledge, questioning and affirming statements, and writers’ craft components to nurture relationships and offer feedback aligned with children’s zone of proximal development.
SNOOKER: a dataset generator for helpdesk services
Authors: Ferreira Leonardo , Silva Daniel Castro , Uriarte-Itzazelaia Mikel 
Published: November 2024

AbstractThe availability of suitable datasets and data generators is crucial for developing intelligent systems, especially in helpdesk services. However, the lack of publicly accessible data generators focused on helpdesk operations, where incidents are often closed without detailing the treatment procedures, poses challenges to implementing intelligent systems such as recommender systems. To address this issue, a dataset generator can be employed to simulate helpdesk incidents. This paper introduces SNOOKER (dataSet geNeratOr fOr helpdesK sERvices), a customizable dataset generator designed to create and treat helpdesk tickets, including domain-specific incidents (e.g., cybersecurity) by orchestrating simulated actions and multiple IT teams. SNOOKER’s output is compared against a real anonymized dataset from S21Sec Cyber Solutions by Thales. The datasets are evaluated using Kolmogorov-Smirnov, Kullback-Leibler Divergence, and Hellinger distance tests, with results indicating similar distributions. For example, the first metric returned a low K-S value and a p-value exceeding 5%, while the second and third measures presented 0.003 and 0.03, respectively. Furthermore, experiments with different team configurations revealed that ticket scheduling highly depends on each team’s operators’ numbers and work shifts, increasing with unbalanced shifts and fewer operators.
Model-informed precision dosing of vancomycin in clinical practice: an intervention development study
Authors: Swartling Maria , Hamberg Anna-Karin , Furebring Mia , Tängdén Thomas , Nielsen Elisabet I. 
Published: November 2024

Abstract

Background
Current guidelines recommend dosing vancomycin based on the area under the concentration time curve (AUC) to maximise efficacy and minimise the risk of nephrotoxicity. The preferred approach to AUC-guided therapy is to apply model-informed precision dosing (MIPD). However, the adoption in clinical practice has been slow.

Aim
We aimed to develop an intervention, including a standardised MIPD workflow and an implementation plan for vancomycin AUC-guided dosing, in a Swedish tertiary hospital.

Method
The intervention was developed in a framework-guided process. The design phase included stakeholder feedback (nurses, pharmacists, physicians), local data collection and feasibility testing of intervention components with parallel consideration of implementation aspects. The hypothesised relationships between the different components, implementation strategies and the mechanism of action resulting in expected outcomes were represented by a logic model.

Results
The final intervention consisted of a workflow for MIPD, with defined roles and responsibilities, as well as processes for data and information transfer. Details were provided in supportive documents; an instruction on therapeutic drug monitoring (TDM) sampling and documentation for nurses, and a detailed dosing software instruction for MIPD consultants and clinical pharmacists. Activities to facilitate implementation included the development of a local clinical routine for vancomycin dosing, staff training and recurring MIPD rounds.

Conclusion
An intervention for MIPD, with an implementation plan for AUC-guided dosing of vancomycin, was developed for a tertiary hospital setting. The process can be used as guidance for other institutions with similar context wishing to initiate MIPD.
Content determination in dreams supports the imagination theory
Authors: Gregory Daniel 
Published: November 2024

AbstractThere are two leading theories about the ontology of dreams. One holds that dreams involve hallucinations and beliefs. The other holds that dreaming involves sensory and propositional imagining. I highlight two features of dreams which are more easily explained by the imagination theory. One is that certain things seem to be true in our dreams, even though they are not represented sensorily; this is easily explained if dreams involve propositional imagining. The other is that dream narratives can be temporally segmented, involving events which take place across long spans of time; this makes sense if dreams involve sensory imagining, for we often sensorily imagine narratives during wakefulness in the same way. The two considerations are unified by the fact that both highlight forms of content determination characteristic of imagining.
Testing the waters meetings, retail trading, and capital market frictions
Authors: Alhusaini Badryah , Chapman Kimball L. , White Hal D. 
Published: November 2024

AbstractPre-IPO firms may “test the waters” by meeting privately with investors in order to allow access to management and more time to make an investment decision. However, these meetings have the potential to undermine the SEC’s objectives of protecting investors and supporting market efficiency by allowing institutional investors, but not retail investors, private access to management. We find lower retail trading after IPOs of firms that held testing-the-waters meetings, consistent with the meetings reducing retail investor participation. Moreover, retail investors that still participate in the market in the presence of testing-the-waters meetings have inferior investment outcomes. Nonetheless, we find no evidence of lower overall market liquidity or slower price discovery following testing-the-waters meetings. In fact, we observe a reduction in stock return volatility. Overall our evidence suggests that, while testing-the-waters meetings may harm retail investors, there does not appear to be a negative impact on overall market function.
Fuzzy clustering with Barber modularity regularization
Authors: D’Urso Pierpaolo , De Giovanni Livia , Federico Lorenzo , Vitale Vincenzina 
Published: November 2024

AbstractIn this paper, we propose a new algorithm for the joint clustering of two sets of statistical units $$\mathcal {N}$$
N
and $$\mathcal {M}$$
M
which are also equipped with an adjacency structure which is represented by a bipartite network. Our model is based on the fuzzy Partition Around Medoids, and it combines it with techniques for community detection in bipartite complex networks based on Barber modularity maximization. The goal is to produce a partition of $$\mathcal {N}\cup \mathcal {M}$$

N
∪
M

into clusters, each of which is also identified by two medoids, one in $$\mathcal {N}$$
N
and one in $$\mathcal {M}$$
M
, which represent the typical units in the cluster for each set. Such clusters are optimized so that units in the same cluster both have similar values on their attributes and are likely to be adjacent. We test the algorithm on both simulated and real data, to show how it is able to capture a wide range of different interactions between the distribution of the attributes and the network structure.

Authors: Zagorski Tabea , Arzt Michael , Driendl Sarah , Stark Klaus , Kmiec Lukasz , Stadler Stefan 
Published: November 2024

Abstract
Background
Arterial hypertension (aHT) is a common comorbidity in patients with type 2 diabetes (T2D). The aim of the present analysis was to determine which predictors are associated with the progression of aHT in participants with T2D.

Methods
We analyzed data from the sleep-disordered breathing (SDB) sub-study of the DIACORE study, a prospective cohort study of participants with T2D. Blood pressure values were determined at baseline and after a mean follow-up of 2.7 years in a standardized manner with three repeated measurements at rest. Arterial hypertension was defined as blood pressure ≥140/80 mm Hg. Progression of aHT was defined as systolic blood pressure ≥140 mm Hg at follow-up with a concomitant increase of at least 10 mm Hg.

Results
Of 1122 participants (41% female, age 66 ± 9 years, body mass index 30.7 ± 5.3 kg/m2), 925 had pre-existing aHT at baseline. At follow-up, 280 had aHT with additional progression. Multivariate regression analysis revealed that systolic blood pressure at baseline (odds ratio [95% confidence interval]: 0.984 [0.976;0.993]; p < 0.001) and age (OR [95%CI]: 1.024 [1.002;1.047]; p = 0.015) were associated with progression of aHT, independently of known modulators. Neither SDB nor its treatment were associated with progression of aHT.

Conclusion
In participants with T2D, lower systolic blood pressure at baseline and age but not SDB were associated with progression of aHT.
Trade credit and family control
Authors: Díaz-Díaz Nieves Lidia , García-Teruel Pedro J. , Martínez-Solano Pedro 
Published: November 2024

AbstractThis paper analyses whether trade credit strategies depend on the family identity of the controlling shareholder. We use a sample of 4,022 private Spanish firms for the years 2004 and 2013 and examine family firm heterogeneity by analysing different thresholds of control, involvement in management and firm identification with the family name. The results reveal that family firms have more restrictive trade credit strategies than non-family firms. Moreover, among family-controlled firms, those with the strongest identification between the family shareholders and their firms are the most restrictive. However, family-controlled firms reduced trade credit less after the financial crisis of 2008. These firms supported their customers by limiting the impact of liquidity shocks during the crisis.

ZusammenfassungWie sich internationale Ordnung nach einschneidenden Krisen verändert, bleibt eine zentrale Frage der Internationalen Beziehungen. Aus pragmatistischer Perspektive erfasst der Beitrag Prozesse der Ordnungsbildung als eine soziale Praxis, die sich entlang des Be‑, Zu- und Abschreibens von kollektiven Verantwortlichkeiten entwickelt. Dabei wird empirisch rekonstruiert, wie sich nach dem Afghanistanrückzug die Zusammenhänge, in denen Handlungen als „verantwortlich“ perzipiert werden, verschoben haben.
Effects of subject-specific professional knowledge and skills of physical education teachers on students’ learning progress

Published: November 2024

AbstractAlthough the subject-specific professional knowledge of teachers is considered to be of central importance with regard to the learning performance of their students, there is only sparse empirical evidence on this issue. Moreover, current studies are primarily limited to the subject of mathematics. The aim of this article is to investigate the significance of subject-specific professional knowledge and skills of physical education (PE) teachers on the practical learning gains of their students based on a panel study. In order to measure both non-contextual knowledge and contextual skills on the teachers’ side, paper–pencil tests as well as video and text vignettes were used as test instruments. On the students’ side, practical sport skills were assessed in a pretest–posttest design to evaluate competence growth with regard to complex sports performance. An effect chain with mediation processes was postulated. Multilevel modeling analyzing 1669 students who were taught by 74 teachers could prove significant performance improvements for the students, but none of the four differentiated knowledge dimensions (content knowledge, non-contextual; pedagogical content knowledge, non-contextual; content knowledge, contextual; pedagogical content knowledge, contextual) of the teachers could explain these learning gains. Thus, the results are in line with various studies in mathematics and suggest that direct effects of teachers’ professional knowledge on students’ learning gains seem to be lost. The results therefore suggest that while basic and broad professional knowledge is required for instructional success, specific expertise in certain competence areas does not lead to additional learning success among students. Further research within the EPiC-PE study is needed to provide a more comprehensive picture of the relationships between professional knowledge and skills, classroom behavior, instructional processes, and learning outcomes.
Junior Doctor Retention Strategies: Integrating Knowledge Management with Supportive Leadership and Organizational Climate

Published: November 2024

AbstractThis study aims to evaluate interventions and strategies used to retain junior doctors, with a specific focus on the roles of organizational climate, supportive leadership, and work engagement influenced by effective knowledge management practices. We examine how knowledge management—the systematic process of creating, sharing, using, and managing the knowledge and information of an organization—contributes to creating a favorable organizational climate and supportive leadership strategies. Engaging in a quantitative study with a sample of 950 junior doctors across four Central European countries, we explore the impact of an integrated approach that combines traditional performance-oriented climate models (rational goals model) with knowledge management practices tailored to the unique demands of healthcare settings influenced by current healthcare reforms and bureaucratic systems. Our findings suggest that not only do supportive leadership and a positive organizational climate enhance work engagement among junior doctors, but robust knowledge management practices also play a crucial role in improving retention rates by facilitating continuous learning and effective information sharing. To the best of our knowledge, our research is the first to draw on the synergy between rational goals, organizational climate, supportive leadership, and knowledge management practices to explain the antecedents of junior doctor work engagement and retention. This approach offers new insights into the dynamics of employee retention and underscores fundamental factors influencing junior doctors’ retention, paving the way for a more resilient and thriving healthcare workforce amidst the ongoing turbulence in global healthcare.
