Climbing university rankings under resources constraints: a combined approach integrating DEA and directed Louvain community detection
Authors: Di Leo Simone , Avenali Alessandro , Daraio Cinzia , Wolszczak-Derlacz Joanna 
Published: September 2024

AbstractOver recent years, scholarly interest in universities’ allocation and effective utilisation of financial resources has been growing. When used efficiently, financial resources may improve universities’ quality of research and teaching, and therefore their positions in world university rankings. However, despite the relevance of financial efficiency to university placement in academic rankings, universities’ total available financial resources appear much more significant. In the present study, we propose an innovative methodology to determine realistic ranking targets for individual universities, based on their available financial resources. In particular, we combine data envelopment analysis, as developed by Banker et al. (Manag Sci 30(9):1078–1092, 1984), and a directed Louvain community detection algorithm to examine 318 universities across five countries, considering their ARWU scores alongside key financial indicators (i.e., long-term physical capital, total operating revenues). We identify clusters of universities with similar financial profiles and corresponding ARWU scores, as well as universities that have optimised their use of financial resources, representing benchmarks for similar universities to emulate. The approach is subsequently applied to Italian universities, as a specific national case. The findings may be useful for policy makers and university managers seeking reliable strategies for climbing academic rankings, particularly in countries with limited public investment in higher education.
Are Employees Safer When the CEO Looks Greedy?

Published: September 2024

AbstractIn this study, we explore the relationship between perceived CEO greed and workplace safety. Drawing on insights from the social psychology literature, we theorize that CEOs are cognizant that their perceived greed has implications for how observers respond to failures in workplace safety. Our theorizing points to a somewhat counterintuitive positive relationship between perceived CEO greed and workplace safety. Consistent with our theorizing, we find that the relationship is attenuated when the CEO is insulated from how observers respond to firm conduct and is amplified when the CEO’s characteristics have a larger impact on how observers respond to adverse firm-level events. We contribute to business ethics research on executive greed, on the relationship between CEO traits and (ir)responsible corporate conduct, and on the antecedents of workplace safety.
Assessing the Dual Impact of the Social Media Platforms on Psychological Well-being: A Multiple-Option Descriptive-Predictive Framework
Authors: Oprea Simona-Vasilica , Bâra Adela 
Published: September 2024

AbstractA comprehensive and recent exploration into the relationship between Social Media Platforms (SMP) usage and Social Media Disorders (SMD) is currently investigated as a topic of increasing importance given the surge in SMP use over the last two decades. The approach of analyzing data from 479 individuals across various SMP using clustering is particularly noteworthy for identifying the risk profile of the users and understanding the diverse impacts of SMP on mental health. In this paper, a multiple-option descriptive-predictive framework for assessing the impact of the SMP on the psychological well-being is proposed. This method effectively categorizes mental health states into distinct groups, each indicating different levels of need for professional intervention. Out of 5 clustering algorithms, K-prototypes proved to bring the best results with a silhouette score of 0.596, whereas for predicting clusters, Random Forest (RF) and eXtreme Gradient Boosting (XGB) outperformed K-Nearest Neighbors (KNN) and Support Vector Classifier (SVC), providing the highest accuracy and F1 score (0.993). Moreover, we analyze the connectedness between each SMP, anxiety and depression. Two distinct clusters emerged: Cluster 0 “Stable Professionals”, Cluster 1 “Vibrant Students”, and new instances are seamlessly predicted. While Youtube is the most popular platform among the respondents, Instagram shows a relatively higher correlation with both anxiety (0.256) and depression (0.186), indicating a stronger association with these disorders compared to other platforms.
Mathematical discussion in classrooms as a technologically-supported activity fostering participation and inclusion

Published: September 2024

Abstract
Whole-class mathematical discussion in a problem-solving activity is recognized as a powerful pedagogical activity but also a challenge for teachers who must consider several difficulties that learners might face, particularly in terms of an overload of Working Memory and Executive Functions. This study investigates how the use of a digital platform (Padlet) can support participatory and inclusive mathematical classroom discussion. We proposed a teaching experiment based on graphical tasks anticipating integral calculus to grade 13 students, and we examined how the use of the digital platform plays a role in the construction and interpretation of new mathematical objects emerging from the activity. The use of Instrumental Genesis and Double Instrumental Genesis frameworks allowed us to make the affordances of the tool emerge. As a result, we got evidence of how mathematical discussion may develop as a network of interactions, feedback, and connection of input and discuss examples of how active participation and inclusion are enhanced by the tool affordances. Indeed, the digital platform allowed easy interaction, with many ways to represent and express the ongoing evolution of personal and shared meanings and the possibility to manage the time of the activity. This fostered students’ participation and students which did not participate in previous discussions were actively engaged in it.
Societalized Politics in the German Civil Sphere: The 2015 “Refugee Crisis” and Post-Potsdam Civil Backlash
Authors: Mast Jason L. , Šuber Daniel 
Published: September 2024

AbstractThis article introduces a theory of societalized politics to investigate crisis events in the German civil sphere between 2015 and 2024, and to proffer an answer to the disputed question of the preconditions that facilitated the rapid rise of right-wing populism in the German context. Drawing on civil sphere and societalization theory, the article specifies the foundational cultural elements, or binary cultural codes (BCCs), upon which German political elites crafted meso-level narratives to contest and manage strains in the civil sphere. Through an analysis of communicative and regulative institutions’ responses to the arrival of refugees in 2015, and the publication of the Correctiv.org report and the backlash protests it inspired in 2024, the article charts the rise of the far-right party Alternative für Deutschland (AfD), and explains its success as due in part to its leaders’ capacities to represent themselves and their supporters as embodying the BCC’s civil democratic signifiers. Introducing a theory of societalized politics, the analysis demonstrates a processual approach to the construction and contesting of crisis events that emerge within the civil sphere itself. The article also introduces a civil sphere theory of right-wing populism, which frames the phenomenon as the elevation of nativist, primordial signifiers born foremost of the noncivil spheres of ethnicity and religion. It concludes by arguing that while the German civil sphere is in flux, the post-Potsdam civil protests indicate a significant portion of the nation’s publics remain committed to universalistic, civil democratic principles.
An Archival Study of the Relationship Between Treatment Duration, Functioning, and Out-of-Home Placement for Youth with Serious Emotional Disturbance in a State-Wide Intensive In-Home Family Treatment Program

Published: September 2024

AbstractThe main aim of this study was to evaluate the effectiveness of Pennsylvania’s state-wide intensive in-home treatment for youth with serious emotional disturbance (SED), EcoSystemic Structural Family Therapy-Family Based Mental Health Services (ESFT-FBMHS). Despite its long history of implementation, the program remains empirically under-evaluated. In this archival study, out-of-home placement and youth functioning outcomes were compared across four tiers of length of stay. Given the high-risk population treated in ESFT-FBMHS, it was hypothesized that the families and youth who completed the full duration of treatment (169–224 days) would have better outcomes than those who stopped treatment after 168 days or less. We utilized an ex post facto quantitative research design analyzing archived medical claims data of 2251 youth treated between 2018 and 2022 to assess out-of-home placement rates and analyzed archived data from six domains of the Child and Adolescent Needs and Strengths (CANS; Problem Presentation, Risk Behaviors, Functioning, Child Safety, Caregiver Needs, and Child Strengths) to assess changes in youth functioning post-discharge (90 and 180 days). An analysis using generalized estimating equations (GEE), controlling for potential confounding variables such as demographics and clinical features, suggest that length of stay in ESFT-FBMHS was significantly associated with out-of-home placement and youth improvement on the CANS at both 90- and 180-days post-discharge. As a group, youth with SED who did not complete the full duration of the program had 2–3 times the odds of out-of-home placement at 90 days post-discharge and 1–3 times the odds at 180 days post-discharge as compared to program completers. CANS scores showed improvement in 40.1% of youth who completed the program as compared to only 11.7%–18.2% for those who did not. The results of this study suggest that ESFT-FBMHS is effective for youth with SED as a group and can improve youth functioning and reduce out-of-home placement.
Formation and retrieval of cell assemblies in a biologically realistic spiking neural network model of area CA3 in the mouse hippocampus

Published: September 2024

AbstractThe hippocampal formation is critical for episodic memory, with area Cornu Ammonis 3 (CA3) a necessary substrate for auto-associative pattern completion. Recent theoretical and experimental evidence suggests that the formation and retrieval of cell assemblies enable these functions. Yet, how cell assemblies are formed and retrieved in a full-scale spiking neural network (SNN) of CA3 that incorporates the observed diversity of neurons and connections within this circuit is not well understood. Here, we demonstrate that a data-driven SNN model quantitatively reflecting the neuron type-specific population sizes, intrinsic electrophysiology, connectivity statistics, synaptic signaling, and long-term plasticity of the mouse CA3 is capable of robust auto-association and pattern completion via cell assemblies. Our results show that a broad range of assembly sizes could successfully and systematically retrieve patterns from heavily incomplete or corrupted cues after a limited number of presentations. Furthermore, performance was robust with respect to partial overlap of assemblies through shared cells, substantially enhancing memory capacity. These novel findings provide computational evidence that the specific biological properties of the CA3 circuit produce an effective neural substrate for associative learning in the mammalian brain.
High-throughput exploration of the Na2O-ZrO2-SiO2-P2O5 composition space using thin film material libraries
Authors: Mockute A. , Ludwig A. 
Published: September 2024

AbstractThe composition space Na2O-ZrO2-SiO2-P2O5 was explored using thin film material libraries and high-throughput characterization methods. The combinatorial synthesis comprised non-reactive magnetron co-sputtering at room temperature from two elemental targets Zr and Si, and a compound Na3PO4 target followed by a two-step annealing process. The NASICON phase formed for all compositions on the material library produced at the optimized deposition parameters, also displaying a phase-pure Na1+xZr2SixP3−xO12 (x = 0.4—2.9) region. Analytical TEM analysis of the NASICON phase at a measurement area with stoichiometric composition revealed a fine-grained microstructure and homogeneous Si distribution, in contrast to Na-P excess conditions, where large Si-free NASICON grains have formed.

AbstractHighly ordered spaced titanium dioxide nanotubes were fabricated via electrochemical anodization and modified with titania nanoparticles and copper oxides. Such materials were rapidly annealed in hydrogen atmosphere or conventionally in a tube furnace in air, in which the temperature slowly increases. Applied synthesis procedure can be considered as simple, cost-effective, and environmentally friendly as it allows for reduction in used materials and enhances sustainable engineering. Manipulating the chemical composition of materials by different thermal treatments resulted in various photoelectrochemical activities and density of CO2 adsorption sites. Rapidly annealed nanotubes decorated by copper oxides exhibit excellent electrochemical properties where one electrode combines both: solar to electricity conversion (photocurrent under visible light 30 µA/cm2) and CO2 adsorption systems (18 times higher current after CO2 saturation). Rapidly thermal hydrogenated TiO2 nanotubes with copper oxides had 17 times higher photocurrent and wider absorption band (380–780 nm) than conventionally annealed ones. Furthermore, the crystal planes such as Cu (111), Cu (220), Cu2O (110), CuO (002) and Cu0, Cu+, Cu2+ oxidation states, and oxygen vacancies were recognized for hydrogenated sample. It should be highlighted that thermal annealing conditions significantly affects ability of copper oxide to CO2 adsorption and CO2 reduction reaction for hydrogenated electrode.

Published: September 2024

AbstractAn ideal scintillator for X- and gamma-ray detection should have a high light yield and a high effective atomic number (Zeff). In this study, we developed undoped TlCdCl3 crystals and TlCdCl3:Sb (Sb: 0.5, 1.0 and 1.5 mol%) crystals with high Zeff (TlCdCl3:68.7), as candidate scintillators. The crystals were grown using the self-seeding solidification method, and their photoluminescence (PL) and scintillation properties were investigated. For the undoped TlCdCl3 crystals, emission peaks were observed at 460 nm and 485 nm in the PL and X-ray-induced radioluminescence (XRL) spectra, respectively. For the TlCdCl3:Sb crystals, the PL spectra showed emission peaks at 480, 480 and 500 nm, while the XRL spectra exhibited peaks at approximately 510 nm. The emission bands of the TlCdCl3:Sb crystals were shifted to longer wavelengths than those of the undoped TlCdCl3 crystals. The scintillation decay time constants for the undoped TlCdCl3 crystals were 51 and 2613 ns, whereas for the TlCdCl3:Sb crystals, they were in the range of 65–81 and 4550–7350 ns. These results suggest that the incorporation of Sb3+ ions induces long components of several thousand nanoseconds. The redshift and appearance of these long components indicate that Sb3+ ions act as new luminescence centers in the undoped TlCdCl3 crystal. The scintillation light yield of the TlCdCl3:Sb 1.0 mol% crystal was measured at 10,300 photons/MeV. The doping of Sb3+ ions into the TlCdCl3 lattice improved the scintillation light yield by up to four times compared to the undoped TlCdCl3 crystal.
Domestic Violence and Custody Proceedings: An Analysis of Judicial Decisions in Portugal
Authors: Ferreira Ana Rita , Sani Ana Isabel 
Published: September 2024

Abstract
Purpose
To understand court decisions in custody cases involving allegations of domestic violence, a qualitative study was conducted among Portuguese family court magistrates.

Methods
A nonprobabilistic snowball sampling process, which involved six judges from Portuguese family courts who were authorized by the Superior Magistrate’s Court to participate in an interview, was used to construct the sample.

Results
When the data were analyzed, three main themes emerged, namely, the characteristics of the processes, the factors considered in the judicial decisions, and the impact of shared custody. The results also revealed several legal and extralegal aspects that influence judicial decisions, such as the characteristics of the violence, the mediation process, and the status attributed to victims, suggesting that there are objective and subjective factors in the perpetuation of violence.

Conclusions
Allegations of domestic violence in custody proceedings are not uncommon, and these allegations can complicate the process and delay a decision. Efforts by one parent to restrict contact with the other parent raise suspicions of attempted alienation that tend to undermine the risk assessment. There can also be overreliance on shared custody, potentially undermining children’s safety. The negative impacts of exposure to domestic violence and the instrumentalization of children are recognized, but it is questionable whether they are being prevented to the extent advocated by the Istanbul Convention. The effectiveness of communication between criminal and family courts is also debatable, despite its importance for protecting victims.
Incidence, Causes and Outcomes of Postpartum Hemorrhage in Eastern Ethiopia: A Multicenter Surveillance Study
Authors: Girma Sagni , Tura Abera Kenay , Ahmed Redwan , Knight Marian , van den Akker Thomas 
Published: September 2024

Abstract
Objectives
Maternal mortality remains an unfinished global agenda and postpartum hemorrhage (PPH) remains one of the leading causes. The aims of this study were to describe the incidence, underlying causes, and case fatality rate of PPH in public hospitals in eastern Ethiopia.

Methods
This study was part of a larger Ethiopian Obstetric Surveillance System (EthOSS) project — a multicenter surveillance of women admitted to 13 public hospitals in eastern Ethiopia due to any of the five major obstetric conditions: obstetric hemorrhage, eclampsia, uterine rupture, sepsis, and severe anemia – conducted from April 1, 2021 to March 31, 2022. All registers in maternity units of those hospitals were reviewed to identify eligible women and collect data on sociodemographic and obstetric characteristics, management and maternal outcomes at discharge or death. Findings were reported using descriptive statistics.

Results
Among 38,782 births registered during the study period, 2043 women were admitted with at least one of the five major obstetric conditions. Of these 2043, 306 women (15%) had PPH corresponding with an incidence rate of 8 (95% CI: 7–9) per 1000 births. Uterine atony was the main underlying cause in 77%; 81% of women with PPH received at least one uterotonic drug, and 72% of women for whom blood was requested received at least one unit. Of the 70 hospital based maternal deaths, 19 (27%) died from PPH, making a case fatality rate of 6 per 100.

Conclusions
Although the overall incidence of PPH appeared low, it was still the underlying cause of death in one out of four women who died. The contributing factors might be that one in five women with PPH did not receive any uterotonic drug and the low blood transfusion. Ongoing audit, followed by targeted action, is essential to improve care quality and reduce adverse maternal outcome. The relatively low incidence may reflect under-recording in paper-based records, implying that further research into methods to optimize the surveillance is needed.
A Bhattacharyya-type Conditional Error Bound for Quadratic Discriminant Analysis
Authors: Kabán Ata , Palias Efstratios 
Published: September 2024

AbstractWe give an upper bound on the conditional error of Quadratic Discriminant Analysis (QDA), conditioned on parameter estimates. In the case of maximum likelihood estimation (MLE), our bound recovers the well-known Chernoff and Bhattacharyya bounds in the infinite sample limit. We perform an empirical assessment of the behaviour of our bound in a finite sample MLE setting, demonstrating good agreement with the out-of-sample error, in contrast with the simpler but uninformative estimated error, which exhibits unnatural behaviour with respect to the sample size. Furthermore, our conditional error bound is applicable whenever the QDA decision function employs parameter estimates that differ from the true parameters, including regularised QDA.

Published: September 2024

AbstractWe investigate the Meal Delivery Routing Problem (MDRP), managing courier assignments between restaurants and customers. Our proposed variant considers uncertainties in meal preparation times and future order numbers with their locations, mirroring real challenges meal delivery providers face. Employing a rolling-horizon framework integrating Sample Average Approximation (SAA) and the Adaptive Large Neighborhood Search (ALNS) algorithm, we analyze modified Grubhub MDRP instances. Considering route planning uncertainties, our approach identifies routes at least 25% more profitable than deterministic methods reliant on expected values. Our study underscores the pivotal role of efficient meal preparation time management, impacting order rejections, customer satisfaction, and operational efficiency.
Perceptions of Self-Love Among Orthodox Christians: Clinical and Pastoral Implications
Authors: Buju S. 
Published: September 2024

AbstractUsing an interdisciplinary, empirical perspective, the study explored Orthodox Christians’ perceptions of self-love and its relationship to love of neighbour, love of God and self-sacrifice. Three scales with good reliability were designed and used with 153 Orthodox Christian adults. The main results obtained are as follows: Orthodox Christians have positive perceptions of self-love – they do not see it as a passion or sin as it is described in Christian ascetic literature; they appreciate the importance and benefits of self-love when they perceive it as a separate reality from the love of neighbour and the love of God; some of them have negative or unclear perceptions on the relationship between self-love, love of neighbour and love of God. In this last respect the empirical results of the study contradict important philosophical and theological views. In the study, less than one-quarter of the Orthodox Christians scored high in practising healthy self-love and agreed that self-love can coexist with self-sacrifice in a certain dose or balance. The clinical and pastoral implications of the findings are discussed, and practical suggestions for intervention are proposed.
