A generalization of Lehman’s method
Authors: Hales Jonathon , Hiary Ghaith 
Published: October 2024

AbstractA new deterministic algorithm for finding square divisors, and finding r-power divisors in general, is presented. This algorithm is based on Lehman’s method for integer factorization and is straightforward to implement. While the theoretical complexity of the new algorithm is far from best known, the algorithm becomes especially effective if even a loose bound on a square divisor is known. Additionally, we answer a question by D. Harvey and M. Hittmeir on whether their recent deterministic algorithm for integer factorization can be adapted to finding r-power divisors.
Corporate responsibility and corporate misbehavior: are CSR reporting firms indeed responsible?
Authors: Reitmaier Christine , Schultze Wolfgang , Vollmer Julia 
Published: October 2024

Abstract We investigate whether firms that proclaim a commitment to corporate social responsibility (CSR) by CSR reporting indeed internalize such a commitment and behave more responsibly. We analyze the association of the issuance and quality of voluntary CSR reports with the occurrence, number, and severity of corporate misbehaviors, both preceding and subsequent to CSR reporting. We find a significantly positive association of CSR reporting with our measures of prior and future misbehavior. The results are corroborated by a quasi-natural experiment around the Rana Plaza disaster where we find that the signatories of an accord for better working conditions have significantly higher prior and future misbehavior relative to non-signatories and firms unaffected by the exogenous shock. Our results are in line with legitimacy theory implying that, on average, the firms’ proclaiming commitment to CSR is not a signal of internalized commitment but more likely serves greenwashing and impression management purposes.
Comparative Historical Analysis in Political Theory
Authors: Leader Maynard Jonathan 
Published: October 2024

AbstractTwo important methodological debates in political theory concern (i) the place of historical research and interpretation in normative inquiry; and (ii) the importance of comparing different cultural traditions of political thought. The first question animates a long-standing controversy over the relative importance of ‘history of political thought’ versus ‘philosophy’ in political theory, while the second has been central to the recent growth of ‘comparative political theory’. Despite both debates being concerned, in fundamental ways, with history and comparison, they have remained surprisingly disconnected from broader debates in the humanities and social sciences about the use of comparative history and, in particular, of the prominent methodological approach in political science known as ‘comparative historical analysis’. This may reflect the fact that the debates over history of political thought and comparative political theory have fundamentally revolved around thought—history as the history of thought and comparison as the comparison of thought—whereas comparative historical analysis is more centrally focused on the study of political behaviour. In this paper I suggest that this neglect of comparative historical analysis in political theory represents a missed opportunity. Like other forms of social scientific inquiry, comparative historical analysis can yield important empirical knowledge for political theorists. But I wish to more ambitiously suggest that comparative historical analysis can also be adapted for conducting normative political theory itself. I summarise the key features of comparative historical analysis for political theorists, and explain how its use of historical cases can supplement both the use of imaginary thought experiments and the study of contemporary politics. I then delineate three specific ways in which comparative historical analysis might be used to support normative inquiry: deductive testing, inductive construction, and casuistic elaboration. All three, I argue, can help meet recent calls to bring the study of real political behaviour more centrally into political theory research.

AbstractProtestors recently repurposed the abortion rights’ mantra, “my body, my choice,” to oppose COVID-19 mandates. But do those who oppose public health mandates fully support the right to choose? We answer this question by using exploratory analyses to identify the unique response patterns underlying support for abortion and COVID-19 mandates in random samples from the United States (Study 1; N = 2,331) and New Zealand (Study 2; N = 33,310). Latent profile analyses revealed a small subgroup in both countries (12.6% and 3.4% of the respective samples) who opposed mandates. Yet contrary to the “my body, my choice” rhetoric seen at anti-mandate protests, they also opposed abortion. Across both studies, those in the Anti-Mandate profile tended to be more religious, conservative, and distrustful of institutions. In Study 2, they were also low on cognitive consistency and high on conspiracy belief. Finally, the Anti-Mandate profile was opposed to free speech critical of both the United States and religion (Study 1), high on sexual prejudice (both studies), unsupportive of progressive protests (but supportive of reactionary protests; Study 2), and likely to vote for conservative parties (both studies). These results reveal the mobilization potential of the anti-mandate movement, uncover important contradictions within its members, and illustrate the nuanced ways in which opposition to gender policies (i.e., reproductive rights) coalesce with reactionary protests.
When Successful Action Research is not Legitimized as Scientific Contribution by the Central Sponsors: How can Morten Levin’s Three Pillars of Action Research Support the Arch of Research Collaboration between Large Public Organizations and Universities?
Authors: Dale Stine , Holmemo Marte Daae-Qvale , Kjæmpenes Wenche M. 
Published: October 2024

AbstractMorten Levin’s work on Action Research (AR) clearly stated that the three pillars participation, action and research was equally important. During his long practice as an AR pioneer, he campaigned for the legitimacy of AR within academia. In this paper we investigate how AR is perceived as sound research within a large and distributed organization. We present a retrospective case study based on a research collaboration between UiT The Artic University of Norway (UiT) and the Norwegian Labour and Welfare Organization (NAV), that fostered an AR project together, ‘Work inclusion, learning and innovation’ (ALIN), but later led to the termination of the collaboration agreement. The ALIN project fulfils all the criteria for being a successful AR project in terms Levin’s action, research and participation criteria. However, external audit and central NAV actors had different expectations of successful institutional research collaboration. Through our case we illustrate several conflict dimensions within the three AR pillars that must be challenged to strengthen the legitimacy of AR. The debate on rigour and relevance should not be limited to academic fields and include various actors and decision makers within large and distributed organizations.
Mixed-precision pre-pivoting strategy for the LU factorization
Authors: Sahraneshinsamani Nima , Catalán Sandra , Herrero José R. 
Published: October 2024

AbstractThis paper investigates the efficient application of half-precision floating-point (FP16) arithmetic on GPUs for boosting LU decompositions in double (FP64) precision. Addressing the motivation to enhance computational efficiency, we introduce two novel algorithms: Pre-Pivoted LU (PRP) and Mixed-precision Panel Factorization (MPF). Deployed in both hybrid CPU-GPU setups and native GPU-only configurations, PRP identifies pivot lists through LU decomposition computed in reduced precision and subsequently reorders matrix rows in FP64 precision before executing LU decomposition without pivoting. Two variants of PRP, namely hPRP and xPRP, are introduced, differing in their computation of pivot lists in full half-precision or mixed half-single precision. The MPF algorithm generates FP64 LU factorization while internally utilizing hPRP for panel factorization, showcasing accuracy on par with standard DGETRF but with superior speed. The study further explores auxiliary functions required for the native mode implementation of PRP variants and MPF.
Design and Evaluation of pH-Sensitive Pectin Films Infused with Anthocyanin-Rich Extracts from Australian Native Fruits for Intelligent Food Packaging Applications
Authors: Nastasi Joseph Robert , Hay Thomas Owen , Fitzgerald Melissa A. , Kontogiorgos Vassilis 
Published: October 2024

AbstractThis study investigates the incorporation of anthocyanin-rich extracts from Mountain Pepper Berry (MPB) and Queen Garnet Plum (QGP) into pectin-based films to develop pH-sensitive indicators. Using glycerol as an extraction solvent, significant differences in anthocyanin composition were identified: MPB extracts contained a diverse range of anthocyanin species, with a total content of 267.13 ± 5.21 mg L⁻¹, compared to the predominantly cyanidin-based QGP extracts, with 222.14 ± 1.61 mg L⁻¹. Differences in anthocyanin structures were elucidated using UPLC-Q-ToF-MS/MS analysis. FTIR and UV-Vis spectroscopy were used to assess the compatibility of the extracts with pectin and the homogeneity of anthocyanins within the film structure. Mechanical testing revealed that MPB films exhibited superior tensile strength (8.53 ± 0.51 MPa), stiffness (2274 ± 158.64 gmm− 1), and energy to failure (141.7 ± 16.23 J m− 3) compared to QGP films, which had lower tensile strength (7.74 ± 0.32 MPa), stiffness (1947 ± 125.82 gmm− 1), and energy to failure (115 ± 18.81 J m− 3). Both film types displayed similar moisture content (MPB: 48.89%, QGP: 48.13%) and water vapour permeability, indicating comparable barrier properties. When exposed to volatile ammonia, QGP films showed a more pronounced colour change, attributed to their anthocyanin profile, with a notable shift from red to brown. This research highlights the potential of glycerol-extracted anthocyanins from Australian native fruits as functional additives in pectin films, offering promising applications for intelligent packaging with enhanced mechanical performance and responsive colour-changing properties.

Hickam’s Dictum: An Analysis of Multiple Diagnoses
Authors: Aberegg Scott K. , Poole Brian R. , Locke Brian W. 
Published: October 2024

Abstract

Background
Hickam’s dictum (“a patient can have as many diseases as he damn well pleases”) has been touted as a counterargument to Ockham’s razor, which enjoins clinicians to seek a single, simple, or unifying diagnosis. Yet the phenomenon of multiple diagnoses has not been formally analyzed.

Methods
We evaluated multiple diagnoses using three methods of inquiry: (1) a review of 83 case reports; (2) a review of 220 cases from the New England Journal of Medicine; and (3) an online survey of providers’ intuitions.

Results
Eighty-three published case reports claimed to instantiate Hickam’s dictum or violate Ockham’s razor. All reported a primary diagnosis that explained the presenting illness, and one or more additional diagnoses which could be classified into four categories: (1) an incidentaloma (n = 21; 25.3%); (2) a pre-existing disease (n = 26; 31.3%); (3) a disease causally linked to the primary diagnosis (n = 33, 39.8%); and (4) a causally unrelated second disease contributing to the acute presentation (n = 3, 3.6%). Among 220 cases from the New England Journal of Medicine, all reported a unifying final diagnosis. In an online survey, 265 respondents recruited using social media evaluated four hypothetical cases with multiple diagnoses representing this categorization scheme. A majority of respondents (79%; 95% CI, 74–84%) chose the case representing category 4 — a coincident, causally unrelated second diagnosis — as the most unlikely or surprising diagnostic combination.

Conclusion
Multiple diagnoses commonly occur. However, the majority of the multiple diagnoses we analyzed were causally linked, or represented incidentalomas or known pre-existing diseases. These diagnostic combinations were unsurprising to a majority of surveyed providers. We show that multiple diagnoses can be arranged in a framework that considers time, probability, and causation. This framework reconciles the alleged conflict between Hickam’s dictum and Ockham’s razor and has greater practical and pedagogical utility.
Study on the Interaction Dynamics of Magnesium and Molten Cast Iron: A Chill Casting Perspective
Authors: Adhiwiguna Ida B. G. S. , Horn Lucas , Deike Rüdiger 
Published: October 2024

Abstract
This study presents a reassessment of the role of magnesium in the production process of cast iron. Through detailed experimentation involving an interrupted reaction process employing a chill casting approach in a copper mold, several reaction products that emerged during the high-temperature interaction between magnesium and cast iron were thoroughly examined. Two cast irons with different chemical compositions, notably different sulfur contents, were used to describe the contribution of magnesium during desulfurization and nodularization. The designed approach successfully revealed that rapid deoxidation and desulfurization reactions of cast iron involving liquid magnesium take place before following its ignition characteristics. Furthermore, the behavior of dissolved carbon concerning the remaining magnesium and magnesium-containing reaction products in molten iron is also empirically identified. Specifically, large graphite flakes and an indication of solidification behavior shifting are circumstantially detected in the magnesium-rich regions, which, to a certain extent, can provide additional insight into the role of magnesium during graphite nucleation.

Abstract
Objective
We investigated and compared the long-term (6-month) histologic changes in a rat model of sublobar resection created using electrocautery or stapler techniques.

Methods
Nine-week-old male rats were anesthetized and intubated; thoracotomy with sublobar resection was performed in the right middle lobe using electrocautery or stapler techniques. Histological examination was performed at 2, 4, 8, 12, and 24 weeks post-surgery to assess long-term effects on lung tissue repair and morphologic changes. Lung expansion and alveolar epithelial cell proliferation were evaluated by measuring the mean linear intercept and counting the number of alveolar type I and II cells.

Results
The electrocautery group showed signs of lung self-repair at the resected area over time, with inflammatory cell infiltration followed by growth of vessels and bronchioles. Mesothelial cells covered the resected area by 2 weeks; elastic fibers gradually connected from both sides by 24 weeks. Lung expansion, measured by mean linear intercept, was initially small below the electrocautery resection area at 2 weeks but recovered from 4 to 24 weeks. The stapler group showed persistently small mean linear intercept over time. In the electrocautery group, the number of alveolar type II cells was higher just below the resection than in other areas from 2 to 24 weeks, followed by alveolar type I cells (4 to 24 weeks). The stapler group showed a transient alveolar type II cell increase at 2 weeks.

Conclusions
Compared to the stapler technique, electrocautery may provide advantages for postoperative lung repair by promoting lung expansion and alveolar epithelial cell proliferation.

Menschenkunde in strukturdynamischer Absicht
Authors: Bormuth Matthias 
Published: October 2024

ZusammenfassungNach Karl Jaspers und Kurt Schneider entwickelte Werner Janzarik in der Heidelberger Schule ein psychopathologisches Denken, das methodisch an Nietzsches Verstehenslehre anknüpfte. Der strukturdynamische Ansatz rekurrierte zudem auf dessen Willensphilosophie, deren Grund Arthur Schopenhauer gelegt hatte. Als Alternative zu anthropologisch psychiatrischen und psychoanalytischen Modellen entwarf Janzarik eine kulturwissenschaftliche Perspektive, die empirische und spekulative Elemente verknüpft und subjektive Wertprämissen bietet. Die Pathographie Nietzsches zeigte dabei die Spannung zwischen asketischen und expansiven Aspekten in der Bildung des Willens, der nach Janzarik Gegenspieler des vitalen Wollens ist.Um die heuristische Triftigkeit des strukturdynamischen Denkens zu erweisen, behandelte er v. a. forensische Kasuistiken und war zuletzt offen für literarische Fälle. Janzarik selbst widmete sich in diesem Sinne spät auch Goethe, dessen künstlerische und wissenschaftliche Kreativität für ihn strukturelle Parallelen besitzen.Der strukturdynamische Ansatz bewegt sich theoretisch in einer Vielzahl wissenschaftlich-philosophischer Ansprüche, die Janzarik interdisziplinär und synthetisch in seiner Menschenkunde verknüpft. Seine Texte verbergen die subjektiven Wertprämissen meist hinter einer abstrahierenden wie komplexen Sprache. Diese Maske der Objektivität führt mit Nietzsche zu einem nüchternen Pathos, das implizit mit Max Weber für ein von persönlichem Pathos durchzogenes Denken spricht. Aber zugleich vermag der späte Janzarik Selbstbeobachtungen in luzider Nüchternheit zu objektivieren.
Rollenverständnis und Haltungsfragen bei der strafrechtlichen Begutachtung
Authors: Habermeyer Elmar 
Published: October 2024

ZusammenfassungDer Beitrag befasst sich mit den Unterschieden, aber auch Gemeinsamkeiten der forensisch-psychiatrischen Begutachtung und Therapie. Er macht deutlich, dass medizinethische Maximen in beiden Arbeitsbereichen gültig sind. Psychotherapeutische Expertise und eine therapeutische Haltung sind von hoher Bedeutung für die gutachterliche Untersuchung bzw. die Aussagekraft der dabei erhobenen Befunde. Außerdem beeinflusst die Wahrnehmung der Begutachtung durch die zu begutachtende Person deren Einstellung zur Therapie, weshalb ein transparenter und psychoedukativer Ansatz empfohlen wird.
New trends in didactic research in university mathematics education
Authors: Biehler Rolf , Durand-Guerrier Viviane , Trigueros María 
Published: October 2024

AbstractRecent research in university mathematics education has moved beyond the traditional focus on the transition from secondary to tertiary education and students' understanding of introductory courses such as pre-calculus and calculus. There is growing interest in the challenges students face as they move into more advanced mathematics courses that require a shift toward formal reasoning, proof, modeling, and problem-solving skills. This survey paper explores emerging trends and innovations in the field, focusing on three key areas: innovations in teaching and learning advanced mathematical topics, transitions between different levels and contexts of mathematics education, and the role of proof and proving in advanced university mathematics. The survey reflects the evolving landscape of mathematics education research and addresses the theoretical and practical challenges of teaching and learning advanced mathematics across various contexts.
On Functional Plurality: A Taxonomy of Benign and Problematic Functions
Authors: Vilchis Rogelio Miranda 
Published: October 2024

AbstractPhilosophers interested in conceptual engineering take it for granted that the same concept can unproblematically play diverse functions, but this view overlooks the fact that conceptual and functional change often impair concepts and even functions themselves. I demonstrate that while conceptual and functional engineering may improve concepts and functions, they can also produce detrimental effects. Therefore, it is crucial to carefully assess the potential benefits or problems before making any modifications. Frequently, we overlook the fact that, for instance, adding extra functions to our concepts modifies them; this may increase, but also impair, their theoretical and practical efficacy. I analyze and clarify these possibilities through a general classificatory framework encompassing concepts, functions, and conceptual and functional change. The larger aim of this paper is to bring attention to these complex and under-researched relationships and pave the way for further research in this area.

AbstractThis rapid communication highlights the correlation between protein kinase B alpha (AKT1)-phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha (PIK3CA)- phosphatase and tensin homolog (PTEN) alterations and clinicopathological factors in Japanese patients with metastatic recurrent breast cancer (mBC). This study analyzed 1967 patients with luminal-type breast cancer who underwent cancer gene panel testing. The results demonstrated that AKT pathway alterations, including PI3K/AKT/PTEN, occurred in 1038 (52.8%) cases. Patients with AKT pathway mutations were older (p = 0.002) and had a higher rate of invasive lobular carcinoma (ILC) histology (p = 0.001), progesterone receptor (PgR) positivity (p = 0.006), and bone metastases (p = 0.001), and a lower rate of germline BRCA2 (p < 0.001). Comprehensive genomic profile results demonstrated a higher tumor mutational burden (TMB) (< 0.001) and lower tumor BRCA1/2 expression (< 0.001) in patients with mutations in the AKT pathway. These results are crucial for characterizing candidates for AKT pathway-targeted molecular therapies and conceptualizing optimal treatment strategies. Clinical trial registration: This study is an observational study and is therefore not registered with the clinical trials registration.
