Abstract
Purpose
To develop a classification tree via semiquantitative analysis for ultrasonographic breast composition assessment using routine breast ultrasonography examination images.

Methods
This study retrospectively enrolled 100 consecutive normal women who underwent screening mammography and supplemental ultrasonography. Based on sonographic breast composition, the patients’ breasts were classified as nondense or dense, which were correlated with mammographic breast composition. Ultrasonographic breast composition was classified based on the fibroglandular tissue (FGT) thickness-to-subcutaneous fat and retromammary fat (FAT) thickness ratio. In addition, the presence of a high glandular tissue component (GTC) in FGT or the presence of evident fat lobules in FGT was investigated. The cutoff point between the nondense and dense breasts was calculated from the area under the curve (AUC).

Results
All cases with a high GTC were dense breasts, and all cases with evident fat lobules in the FGT were nondense breasts. The AUC of the FGT thickness-to-FAT ratio of all cases, the group without a high GTC, the group without evident fat lobules in the FGT, and the group without a high GTC or evident fat lobules in the FGT were 0.93, 0.94, 0.99, and 1, respectively.

Conclusion
The presence of a high GTC indicated dense breasts, and the presence of evident fat lobules in the FGT represented nondense breasts. For the remaining cases, the cutoff point of the FGT thickness-to-FAT thickness ratio was 0.93 for ultrasonographic two-grade scale breast composition assessment with 100% accuracy.
Experimental Method to Determine the Draping Behavior of Auxiliary Materials for the Vacuum Bagging of CFRP Parts on Doubled-Curved Surfaces
Authors: Schmidt-Eisenlohr Clemens , Voggenreiter Heinz , Kupke Michael 
Published: May 2024

AbstractThe production costs of aircraft primary structures made of carbon fibre reinforced polymer (CFRP) are significantly higher than for comparable metal-based structures. Today substantial effort is made to achieve a sufficient reproducibility and parts’ quality in manufacturing processes of CFRP structures. Especially the sub process vacuum bagging for infusion processes is still expensive. One of the reasons is the complex positioning of the flexible auxiliary materials which have to be stacked on the preform. During the positioning on doubled-curved surfaces these materials tend to form wrinkles, which can lead to defects of the composite part. Yet, a defined description of the wrinkling behavior of the auxiliary materials on doubled-curved surfaces does not exist. In this work a characterization of the wrinkling behavior on doubled-curved surfaces is investigated for the auxiliary materials of the Vacuum Assisted infusion Process (VAP®): release film, perforated peel ply, flow media, membrane and vacuum foil. Therefore, an experimental test method is derived similar to established hemisphere deformation test methods. The wrinkling behavior for the specific VAP auxiliary materials is empirically determined on differently curved surface geometries. It is shown that the draping behavior can be characterized by partial wrinkle-free surfaces between the wrinkles. A material specific threshold is derived to determine the appearance of wrinkles. The work shows that a characterization of the draping behavior of auxiliary materials on doubled-curved surfaces is possible. With the gained knowledge the potential for an increase of the vacuum bagging reproducibility is given.
Dominant subspaces of high-fidelity polynomial structured parametric dynamical systems and model reduction
Authors: Goyal Pawan , Duff Igor Pontes , Benner Peter 
Published: May 2024

AbstractIn this work, we investigate a model order reduction scheme for high-fidelity nonlinear structured parametric dynamical systems. More specifically, we consider a class of nonlinear dynamical systems whose nonlinear terms are polynomial functions, and the linear part corresponds to a linear structured model, such as second-order, time-delay, or fractional-order systems. Our approach relies on the Volterra series representation of these dynamical systems. Using this representation, we identify the kernels and, thus, the generalized multivariate transfer functions associated with these systems. Consequently, we present results allowing the construction of reduced-order models whose generalized transfer functions interpolate these of the original system at pre-defined frequency points. For efficient calculations, we also need the concept of a symmetric Kronecker product representation of a tensor and derive particular properties of them. Moreover, we propose an algorithm that extracts dominant subspaces from the prescribed interpolation conditions. This allows the construction of reduced-order models that preserve the structure. We also extend these results to parametric systems and a special case (delay in input/output). We demonstrate the efficiency of the proposed method by means of various numerical benchmarks.
Redefining Academic Safe Space for Responsible Management Education
Authors: Martineau Joé T. , Cyr Audrey-Anne 
Published: May 2024

Abstract
In a time of increasing polarization, how can we address sensitive topics and ensure that university classrooms remain places of healthy discussions and ethical deliberations? This paper addresses this important question by drawing on unique qualitative data from our students’ accounts of their experience in an organizational ethics course. We developed the course using a novel pedagogical strategy centered around the creation of an artistic portfolio. We find that student engagement in an alternative individual space, such as the artistic portfolio, supports them in developing (inter)personal skills in preparation for constructive participation in sensitive discussions and ethical deliberation in the classroom. Additionally, engagement with the artistic portfolio provides them with an alternative means for alleviating tension that arises from these discussions and a space for expressing their opinions. Our findings highlight the role of the portfolio as an individual safe haven that supports teachers in facilitating a positive classroom atmosphere and guides students through challenging discussions and deliberations intrinsic to responsible management education. Considering these new insights, we advocate for a shift from a collective to an individual perspective on safety in academia. This transition liberates the classroom from the constraints and limitations often associated with the establishment of collective safe spaces.

Abstract
Background
Platinum-based doublet chemotherapy is commonly used in the treatment of non-small cell lung cancer (NSCLC). A growing body of evidence indicates that incorporating antiangiogenic agents into platinum-based chemotherapy may enhance the survival outcomes for NSCLC patients. However, the optimal administration protocol for intravenous recombinant human endostatin (rh-endostatin), an antiangiogenic agent, remains uncertain at present.

Aim
This study aims to investigate the efficacy and safety of 5-d continuous intravenous infusion of rh-endostatin in combination with chemotherapy for patients with advanced NSCLC. The predictive biomarkers for this treatment regimen were further probed.

Methods
This prospective, single-arm multicenter study enrolled a total of 48 patients with advanced NSCLC who were histologically or cytologically confirmed but had not received any prior treatment from January 2021 to December 2022. Prior to the chemotherapy, these patients received a continuous intravenous infusion of rh-endostatin (210 mg) over a period of 120 h, using an infusion pump. The chemotherapy regimen included a combination of platinum with either pemetrexed or paclitaxel, given in 21-day cycles. The primary endpoint of the study was median progression-free survival (mPFS), and the secondary endpoints included median overall survival (mOS), objective response rate (ORR), disease control rate (DCR), and assessment of adverse events (AEs).

Results
The mPFS was 6.5 months (95% confidence interval (CI): 3.8–9.1 m) while the mOS was 12.3 months (95% CI: 7.6–18.5 m). The ORR and DCR was 52.1% and 75.0%, respectively. Leukopenia (52.1%), anemia (33.3%), and thrombocytopenia (20.8%) were the most common adverse effects and these toxicities were deemed acceptable and manageable. In addition, a correlation was noted between elevated serum carcinoembryonic antigen (CEA) levels and decreased PFS and OS.

Conclusions
The incorporation of a 5-day continuous intravenous infusion of rh-endostatin into platinum-based doublet chemotherapy has demonstrated both safety and efficacy in the treatment of advanced NSCLC. Furthermore, the baseline serum levels of CEA may potentially function as a predictor for the efficacy of rh-endostatin when combined with chemotherapy in NSCLC patients.

AbstractStudent outcomes are of great importance in higher education institutions. Accreditation bodies focus on them as an indicator to measure the performance and effectiveness of the institution. Forecasting students’ academic performance is crucial for every educational establishment seeking to enhance performance and perseverance of its students and reduce the failure rate in the future. The main goal of this study is to predict the performance of undergraduate first-level students in the Computer Department during the years 2016 to 2021 to enhance their performance in future by discovering the best algorithm use to analyze the educational data to identify the students’ academic performance. The secondary data was collected by reviewing the Student Affairs Department at the Faculty of Specific Education at Damietta University, in addition to the Statistics Department at the university. The dataset contained 830 instances after excluding 139 instances of missing values, irrelevant rows, and outliers. The dataset was divided into train (577 instances (70%)), test (253 instances (30%)) and involved six features such year, midterm, practical exam, writing exam, final total degree, and grade. This paper use five machine learning (ML) algorithms which was selected according to the literature review and high accuracy in predicting educational data mining: For the purpose of comparison, a number of different machine learning algorithms, such as Random Forest, Decision Tree, Naive Bayes, Neural Network, and K-Nearest Neighbours, were utilized and evaluated with evaluation metrics such as confusion matrix, accuracy, precision, recall, and F-measure. The Random Forest and Decision Tree classifiers emerged as the top-performing algorithms, accurately categorizing 250 instances when predicting students' performance in the statistics course. This was determined based on the findings of the study. Out of a total of 253 instances that were included in the testing set, they only made three incorrect classifications.
Affectivity in its Relation to Personal Identity
Authors: Zaborowski Robert 
Published: May 2024

AbstractMy aim is to propose affectivity as a criterion for personal identity. My proposal is to be taken in its weak version: affectivity as only one of the criteria for personal identity. I start by arguing for affectivity being a better candidate as a criterion for personal identity than thinking. Next, I focus on synchronic vs. diachronic and on ontic vs. epistemic distinctions (my proposal will concern diachronic ontic personal identity) and consider the realm of affectivity in its temporal dimension. In my argument, I rely on the genuineness of affectivity and I exploit chiefly long- or everlasting feelings (or emotions) and those which involve the feeling subject more rather than less. I conclude by stating that genuine long-lasting feelings (or emotions) are constitutive of diachronic ontic personal identity.

Published: May 2024

Abstract
Purpose
The present study investigates healthcare students’ affective, behavioral, and cognitive attitudes toward hypothetical peers with autism spectrum disorder (ASD) and the effect of the ASD label on their attitudes.

Methods
The MAS scale for ASD persons in the postsecondary education (Matthews et al., 2015) was translated and adapted in Greek according to the guidelines of World Health Organization (2016). Participants (n = 444) were randomly divided into three equal groups and completed their demographic information. Each participant read the three vignettes of the Greek-adapted MAS scale describing a communicative interaction with one hypothetical fellow student with autistic characteristics in three different social situations but in each group, the vignette’s character was labeled differently (High-functioning, typical college student, and no-label).

Results
Students in the High-functioning group demonstrated more positive affective, behavioral, and cognitive attitudes toward the vignette characters than students in the no-label condition. Furthermore, students in the typical student group reported more rejective behaviors toward the vignette characters than students in the high-functioning group, implying that atypical behavior evokes rejection and stigmatization, while the label did not. Male students presented more positive cognitive attitudes across study groups in comparison to female students, while previous contact with individuals with ASD did not seem to impact significantly attitudes.

Conclusion
The findings of the study indicate that knowledge of an ASD diagnosis leads to greater acceptance and have important implications for future research, disability policy makers, and university support services.

Authors: LaGrotte Caitlin A. , Bullock Anastasia , Doremus Corey , Aricola Carissa 
Published: May 2024

AbstractCurrent literature lacks data related to the role of psychologists on consultation-liaison (CL) services; previous data indicates only 4% of CL services are run by psychologists, while 32% of liaison mental health services include a psychologist. As CL psychologists’ roles within hospitals grow, it is critical to identify clinical strategies and organizational structures of CL services across hospital systems. The current study seeks to provide a deeper understanding of CL psychologists’ scope of work. Participants (N = 77) (15% response rate) completed a measure developed for this study, exploring psychologist roles, clinical practice, and departmental structures. Thirty-two percent of respondents were in Psychiatry Departments, 58% were in academic medical centers, almost half had training programs and the most frequently utilized billing code was: Given the limited data available, this study provided a contemporary and foundational understanding of the CL psychologist roles as well as future avenues of empirical inquiry such as discrete organization and structural characteristics.
Is there a role for cooperative actors in the management of public housing? Hybrid partnerships as trojan horses for profit extraction or vehicle of housing commons: reflections on a pioneering project in Milan
Authors: Peverini Marco , Bricocoli Massimo , Tagliaferri Anna 
Published: May 2024

AbstractAfter its expansionist phase in the XX Century, in most countries public housing has incurred in a state of long-term crisis that still lasts until today. With long-lasting disinvestment in the Italian public housing, many dwellings and buildings are vacant or in decay. Public housing companies yet rely heavily on dismissal and sales to cover high overheads and low rents. In this context, there has been sporadic experimentation of partnerships between public authorities and cooperative actors in enacting hybrid forms of management as an alternative to the sale of public assets. The article uses the case study of the Quattro Corti project in Milan and experts’ panels in four Italian cities to explore potential innovation pathways for public housing in different contexts and to identify opportunities and challenges of the involvement of cooperatives through partnerships for hybrid management. A main question is whether such partnerships may be trojan horses for profit-actors or vehicles of housing commons. The article contributes to the emerging literature on the role of cooperative actors in public and social housing policies.
Bidirectional Within-Family Effects of Restrictive Mediation Practices and Adolescents’ Problematic Social Media Use

Published: May 2024

AbstractMuch remains unknown about whether restrictive mediation is an effective parenting strategy to prevent or reduce problematic social media use among adolescents. Therefore, this study examined bidirectional within-family effects between two restrictive mediation practices (rule-setting and reactive restrictions) and problematic social media use using random-intercept cross-lagged panel modeling. Three-wave survey data collected among Dutch adolescents (T1: N = 1928, Mage = 13.31 years, SD = 0.91, 43.3% girl) with a 1 year-interval were used. Results showed that within-family changes in problematic social media use symptoms predicted subsequent within-family changes in perceived parental restrictive mediation. More specifically, an increase in symptoms predicted a decrease in rule-setting and an increase in reactive restrictions 1 year later. Within-family changes in perceived parental restrictive mediation practices did not predict within-family changes in problematic social media use symptoms, suggesting that the relation is unidirectional. However, concluding that limiting adolescents’ Internet use is ineffective to prevent problematic social media use would be premature. Future research should investigate whether it may be an effective parenting strategy for a certain subgroup of adolescents or under certain circumstances.
Asymmetric effects of long-term war on human resource development in Af…ghanistan: evidence from NARDL approach
Authors: Hameed Mohammad Ajmal , Rahman Mohammad Mafizur , Khanam Rasheda 
Published: May 2024

AbstractThis study explores the effects of war on human resource development in Afghanistan using non-linear autoregressive distributed lags (NARDL) and asymmetric causality analysis. The results of the NARDL bound test support an asymmetric long-run relationship between predictors. It reveals that positive and negative shocks from the per capita cost of war, child mortality rate, and population growth rate asymmetrically affect the school enrollment rate in both the short and long runs. Furthermore, it shows that positive shocks from per capita GDP and per capita government expenditures on education increase the school enrollment rate, while their negative shocks have adverse effects, in both the short and long runs. This implies that school enrollment is highly sensitive to changes in the per capita cost of war and reacts swiftly. Moreover, the results reveal significant causality from both the positive and negative components of the per capita cost of war, per capita GDP, per capita government expenditures on education, and population growth to both the positive and negative components of the school enrollment rate. However, there is only a causal nexus from the negative component of the child mortality rate to the school enrollment rate. Based on these findings, relevant policy implications are discussed.

Published: May 2024

AbstractMultiheterocyclic inorganic–organic hybrid phosphazenes have robust inorganic ring systems with the stabilities of the phosphorus nitrogen skeleton and many different substituents bonded to the P atoms. In present study, unsymmetrical dispirocyclotriphosphazenes were prepared due to their potential to depict steric hindrance and electronic rearrangement in creating permanent chirality for certain conformational and configurational isomers. These isomers may have an effect on DNA bindings and activitiy against selected fungi and bacteria, remarkably. Herein, tetrachlorocyclotriphosphazenes (1 and 2) were reacted with 9-ethyl-N-methyl-3-carbazolyl-1,2-diaminoethane (3), 9-ethyl-N-ethyl-3-carbazolyl-1,2-diaminoethane (4) and 9-ethyl-N-methyl-3-carbazolyl-1,3-diaminopropane (5) to give the new unsymmetrical cis/trans-dispirocyclotriphosphazenes, [(ClBz/BzSpiro-6)R1(N3P3)(CzSpiro-n)R2]Cl2 (Cz: Carbazolyl; R1:Me R2:Me or Et; n = 5 or 6; trans 6a–11a and cis 6b–11b). Characterizations, chiralities, and photophysical and biological properties of the new compounds were examined. The molecular and crystal structures of cis-6b, cis-7b, trans-9a, cis-9b, trans-10a and cis-10b were determined by single crystal X-ray crystallography. The chiralities of these compounds with unsymmetrical spiro-architectures were confirmed by X-ray crystallography. These results were further proven by 31P NMR data recorded with the addition of a chiral solvent (CSA). Additionally, circular dichroism (CD) spectra also supported the results. Photophysical measurements indicate that these compounds show emission with lifetimes of approximately 5.6–5.9 ns. In addition, the bioactivities of some isomers were found to be different and quite high against some bacterial and yeast strains. Trans-8a was very active against B. cereus (MBC = 78.1 µM), while cis-6b, trans-9a and cis-9b were very active against the pathogenic yeast C. albicans (MFC = 156.3 µM).
