Om språket får bestämma : En hermeneutisk studie av Eugene H. Petersons bibelöversättning
No full textThe purpose of this essay is to examine whether Peterson’s own philosophy of life, as interpreted thorough his articles, can be said to correlate with the content of four translations from his work The Message. By using hermeneutics as method, along with the concept of philosophy of life as applied theory and Wittgenstein’s language-games as a theoretical framework for the contextual understanding of language – this essay intends to analyze how the translations can be understood through the authors language as an expression for his philosophy of life. Hence my research questions are as follows. 1) What philosophy of life can be formulated through the authors articles? 2) How does the translations mirror the authors own philosophy of life? 3) In what way does the result yield reason for an approach of the translations as either literary works or religious writings? This study shows that Petersons philosophy of life sees (1) the world as something through God created and by mankind affected, thus there is room for both good and evil in it but it is at all times through holiness spirited along with (2) man as an active contributor in his relationship with God, where he is constantly being tested and is required to work in order to not fall in disgrace but he is always capable of doing good. The translations correlate with expressions for Petersons philosophy of life in the articles through three characteristics: 1) viewing women as equal and highly valued, 2) viewing faith as an active dedication and 3) views of self-realization through the belief in God. Finally, the results of this study give reason to approach Petersons translations as literary works, rather than religious writings, with the motivation that these translations are Petersons personal interpretations which can be derived from him as a lone author along with signs of correlations to his own philosophy of life. This motivates further research within this particular area – in order to better understand how interpretations come about with philosophy of life as an important variable, focusing on the individuals’ own outlook on life rather than the life surrounding the individual.
Improved measurement of absolute branching fraction of the inclusive decay Λ+c → K0SX
No full textBy analyzing 4.5 fb−1 of e+e− collision data accumulated with the BESIII detector at center-of-mass energies ranging from 4599.53 MeV to 4698.82 MeV, we report the measurement of the absolute branching fraction (BF) of the inclusive decay Λ+c→K0SX using the double-tag technique. The result is B(Λ+c→K0SX) = (10.9 ± 0.2 ± 0.1)%, where the first uncertainty is statistical and the second is systematic. This result indicates that there are still undiscovered decay channels containing K0S in the final state with a combined BF of (3.0 ± 0.4)%. The BF of the inclusive decay Λ+c→¯K0/K0X is calculated to be B(Λ+c→¯K0/K0X) = (21.8 ± 0.4 ± 0.2)%, The result is in agreement with the prediction of the statistical isospin model.For complete list of authors see http://dx.doi.org/10.1007/JHEP06(2025)194</p
Effectiveness of nighttime vs full-time bracing in the treatment of moderate-grade adolescent idiopathic scoliosis : a secondary analysis of the CONTRAIS trial
No full textBackground and purpose: Data on effectiveness of nighttime bracing compared with full-time bracing in adolescent idiopathic scoliosis is scarce. We aimed to investigate risk of curve progression and surgery with nighttime bracing vs full-time bracing for patients with moderate-grade adolescent idiopathic scoliosis. Methods: Skeletally immature individuals with idiopathic scoliosis (25°-40°) treated with a nighttime brace as part of a parallel-group randomized controlled trial (RCT) were compared with non-participants treated with a full-time brace. In the case of curve progression of more than 6 degrees in the nighttime brace group individuals were offered transition to a full-time brace. Surgery was offered if curve sizes were 45° or larger. Results: Median age at treatment start was 12.8 years (nighttime brace n = 45, full-time brace n = 44). Female sex (odds ratio [OR] 6.5, 95% confidence interval [CI] 1.1-37.4), lower Risser grade (OR 1.6, CI 1.01-2.7), and larger curve size at the beginning of brace treatment (OR 1.4, CI 1.2-1.5) increased the risk of curve progression to ≥ 45°. Major curves in the groups were similar at median 33 months' follow-up (P = 0.7). After 94 months of follow-up, 11 patients in the nighttime brace group and 6 in the full-time brace group had undergone surgery (OR 2.0, CI 0.7-6.1). Conclusion: Nighttime bracing, including a possibility to transition to full-time brace in the case of progression, demonstrated comparable effectiveness in preventing curve progression, but a tendency to a higher risk of surgical treatment
Framework for Rotating Electrical Machines using FEM
No full textThis project addresses the modernization and porting of a finite-element-method framework for rotating electrical machines from Ubuntu 16 to Ubuntu 24. The codebase comprising of C, C++, Fortran, Lex and Yacc relied on outdated compiler behaviors and build scripts that are incompatible with modern toolchains. The goal was to update and replace K&R-style declarations with modern ANSI-style, legacy Fortran syntax, incorrect header files and resolve linker errors between different working directories. Lex/Yacc syntax were recompiled with Flex/Bison and build scripts were used to speed up the compiling process. The updated framework now compiles on Ubuntu 24, producing the interactive GUI (AceMain) and analysis routines (Acek01). Simulations for magnetic field plotting and mesh visualization run without error. This successful port enables continued use of the framework for two-dimensional steady-state FEM analysis on modern systems.
Social security and retirement around the world : lessons from a long-term collaboration
No full textDeclining labor force participation of older men throughout the 20th century and recent increases in participation have generated substantial interest in understanding the effect of public pensions on retirement. The National Bureau of Economic Research's International Social Security (ISS) Project, a long-term collaboration among researchers in a dozen developed countries, has explored this and related questions. The project employs a harmonized approach to conduct within-country analyses that are combined for meaningful cross-country comparisons. The key lesson is that the choices of policy makers affect the incentive to work at older ages and these incentives have important effects on retirement behavior
Anomaly Detection in Bernoulli Time Series
No full textIn the industry, we might encounter a series of events that we expect to be independent, without being sure. At some point the events may stop being independent from each other. The thesis develops a way to identify anomalies where presumably independent events from a Bernoulli time series see rapidly changes in probability. Rapidly changing probability may indicate activity that is dependent. Bands similar to ordinary bollinger bands from finance are used
Comparative proton and photon treatment plans in children treated for neuroblastoma
No full textBackground and purpose: Neuroblastoma is the most common extracranial solid tumour in children. Radiotherapy is commonly part of the multimodal treatment for high-risk patients. The aim of this study is to analyse doses to organs at risk (OAR) in comparative proton and photon treatment plans for children treated for neuroblastoma and report side effects. Patient/material and methods: All children in Sweden treated with curative intent radiotherapy for abdominal neuroblastoma in 2017-2024 with comparative proton and photon treatment plans were retrospectively identified through a national registry (RADTOX), where data on side effects were collected. Doses to OAR were compared in each patient's proton and photon treatment plans. Results: A total of 30 children with a median age of 45 months (range 11-150) were included. The lowdose spread was significantly lower in the proton compared to the photon treatment plans measured as Body V5Gy and V10Gy (p < 0.001). Furthermore, the mean doses to the bowel bag, kidneys, liver, pancreas, and spleen were significantly lower in the proton plans. The median follow-up was 14 months (1-61), and the 2-year overall survival was 75.3%. While acute radiotherapy related grade ≥ 2 side effects were experienced by 12 patients (40%), late side effects were experienced by 7 patients (13%). The most common side effects were haematological and from the upper gastrointestinal tract. Interpretation: In selected cases, proton treatment can offer lower doses to OAR and less low-dose exposure compared to photon treatment in children treated for abdominal neuroblastoma. Whether this translates into a clinical benefit is currently unclear and should be evaluated in future studies
Higher Form Symmetries in Maxwell Theory
No full textWe review the structure of generalized global symmetries in quantum field theory, with a detailed focus on Maxwell theory. We explain how ordinary global symmetries extend to higher-form symmetries, and analyze the electric and magnetic 1-form symmetries in Maxwell theory. We construct the associated conserved charges using the dual field strength, and discuss key properties such as gauge invariance and electromagnetic duality. We describe spontaneous symmetry breaking in the context of higher-form symmetries. Finally, we study the gauging of discrete 1-form symmetry subgroups in Maxwell theory, showing how this procedure modifies the spectrum of line and surface operators. We also explain how such gauging can lead to non-invertible codimension-1 topological defects when combined with S-duality.Vi ger en översikt av strukturen hos generaliserade globala symmetrier i kvantfältteori, med särskilt fokus på Maxwellteorin. Vi förklarar hur vanliga globala symmetrier kan utvidgas till högreformsymmetrier och analyserar de elektriska och magnetiska 1-formsymmetrierna i Maxwellteorin. De tillhörande bevarade laddningarna konstrueras med hjälp av den duala fältstyrkan, och centrala egenskaper såsom gaugeinvarians och elektromagnetisk dualitet diskuteras. Vi beskriver hur spontant symmetribrott kan uppträda i samband med högreformsymmetrier. Slutligen undersöker vi gauging av diskreta 1-formsymmetrigrupper i Maxwellteorin och visar hur denna procedur förändrar spektrumet av linje- och ytoperatorer. Vi förklarar också hur en sådan gauging, i kombination med S-dualitet, kan ge upphov till icke-inverterbara topologiska defekter av kodimension 1
