Where’s the Body?: Victimhood as the Wrongmaker in Abortion
Authors: Derin Jacob 
Published: November 2022

AbstractMuch of the work in moral philosophy and the political debate on abortion has focused on when in human development personhood begins. In this article, using a variant of Derek Parfit’s view on personal identity, I instead frame the question as one of victimhood. I argue for what I call the Victim Requirement for the wrongness of killing–killing is wrong only if there is an identifiable victim. An identifiable victim is, temporally speaking, in the midst of a chain of psychological connections in the sense of “Relation R.” I go on to argue for a version of psychological identity which makes consciousness a necessary condition of rational self-interest and numerical identity across time. The implications for the abortion debate, based upon the best neurological evidence, are that abortion cannot be wrong before at least 22 weeks of pregnancy and perhaps significantly later. I then respond to alternatives to my Victim Requirement and argue that they either fail on their own merits or are deeply problematic. Finally, I discuss the role of autonomy and consent in a world where fetal consciousness develops much earlier.
Dynamic and monotonic response of Monopile Foundations for Offshore wind turbines using centrifuge testing

Published: November 2022

AbstractThe seismic response of monopile foundations is a growing area of research as the offshore wind industry expands worldwide, including in earthquake prone regions of the world. This paper presents dynamic centrifuge tests aimed at investigating the dynamic response of monopiles in both dry and saturated sandy soils. The latter case includes soil liquefaction under strong input motions, with measured excess pore pressures indicating liquefaction. The natural frequency of the monopile-soil system is experimentally determined by measuring the response to a sine sweep motion. Strong earthquakes are then applied at this frequency and its harmonics. This paper discusses the response of the monopile in terms of the peak accelerations observed in the dry and saturated tests, as well as using response spectra and amplification ratios. The dynamic bending moments along the pile are also measured to infer the bending moment profile with depth. Finally, two identical monopiles are pushed-over in each of the centrifuge tests to establish the pre and post-earthquake monotonic response, including the lateral stiffness and capacity, which are compared for the dry model tests and the saturated case.
Circadian clocks signal future states of affairs
Authors: Pridmore Brant 
Published: November 2022

AbstractOn receiver-based teleosemantic theories of representation, the chemical states of the circadian clocks in animal, plant and cyanobacterial cells constitute signals of future states of affairs, often the rising and setting of the sun. This signalling is much more rigid than sophisticated representational systems like human language, but it is not simple on all dimensions. In most organisms the clock regulates many different circadian rhythms. The process of entrainment ensures that the mapping between chemical states of the clock and the daily light-dark cycle is adjusted to deal with seasonal changes. In regulating anticipatory behaviour, the states of the clock look forward both to the time the behaviour is supposed to happen and the later time when the anticipated circumstances are supposed to arise. The case of the circadian clock shows that purely indicative signals can arise in very basic biological systems and brings into sharp relief the trade-offs involved in characterizing representational systems. On receiver-based teleosemantic theories, future-directed signals are not restricted to complex multicellular organisms but are ubiquitous in the biological world.
The phase space structure of retrograde mean motion resonances with Neptune: the 4/5, 7/9, 5/8 and 8/13 cases

Published: November 2022

AbstractWe compute planar and three-dimensional retrograde periodic orbits in the vicinity of the restricted three-body problem (RTBP) with the Sun and Neptune as primaries and we concentrate on the dynamics of higher-order exterior mean motion resonances with Neptune. By using the circular planar model as the basic model, families of retrograde symmetric periodic orbits are computed at the 4/5, 7/9, 5/8 and 8/13 resonances. We determine the bifurcation points from the planar circular to the planar elliptic problem and we find all the corresponding families. In order to obtain a global view of the families of periodic orbits, the eccentricity of the primaries takes values in the whole interval $$0<e'<1$$

Immobilization of a cellulose carbamate-type chiral selector onto silica gel by alkyne-azide click chemistry for the preparation of chiral stationary chromatography phases
Authors: Bui Cuong Viet , Rosenau Thomas , Hettegger Hubert 
Published: November 2022

AbstractA new synthesis strategy for the preparation of cellulose derivative-based chiral selectors and the subsequent mild immobilization onto pre-functionalized silica gel are introduced, utilizing Cu(I)-catalyzed alkyne-azide Huisgen cycloaddition (“click”) chemistry. A cellulose 3,5-dimethylphenyl carbamate derivative carrying propynyl carbamate groups was prepared by a combination of carbonate aminolysis and isocyanate chemistry. For immobilization, 3-azidopropyl-functionalized silica gel as an inert carrier was used, synthesized via a 3-chloropropyl intermediate. The chiral selector, as well as the inorganic/organic hybrid materials (silica gel/chiral selector), were comprehensively characterized by ATR-FTIR, solid-state 13C and 29Si NMR, liquid-state NMR, GPC, TGA, and elemental analysis. The enantioseparation performance of the immobilized-type chiral stationary phase was evaluated by HPLC with a set of representative chiral test analytes and different eluents and compared to a respective coated-type (=non-covalently bound) chiral stationary phase carrying the same selector quality and quantity on the same silica gel matrix. The immobilization did not adversely affect the chiral separation performance; on the contrary, in some chromatographic separations the immobilized-type chiral stationary phase surprisingly even surpassed the coated reference material.

Published: November 2022

AbstractThe 21st century has ushered in accelerated new technologies, new knowledge and new information and the fourth industrial revolution (4IR) – causing rapid changes in the way humans live and work and resulting in an outcry for educational reforms globally. Many frameworks and debates centred on rethinking and reshaping the curriculum including what knowledge, skills, values and attitudes should be taught to prepare learners to thrive in the 21st century, have been developed. This study examined the students’ conceptions of 21st century education in four diverse schools in Zimbabwe. The study is framed by the powerful theory and the complexity theory. The study used a quantitative non-experimental correlation design to collect data from four secondary schools, three of which follow the ZIMSEC syllabus and the other, a private school that follows a Cambridge syllabus. The questionnaire was adapted from the Partnership for 21st century framework (P21) and (Ravitz, 2014) to fit the Zimbabwean context. A total of 236 students and 93 took part. Exploratory and confirmatory factor analyses and ANOVA were used to analyse the data.The results showed that the students’ conception of 21st century skills is defined by three factors: the learning of self-management, learning skills and values and learning process. Students most strongly endorsed self-management.It is envisaged that the proposed model of Zimbabwean students’ conceptions of 21st century skills will act as a baseline for theory, policymakers, head teachers, teachers and teacher education colleges to realign the current teaching to fit the 21st century curricula.
Combinatorial and topological aspects of path posets, and multipath cohomology
Authors: Caputi Luigi , Collari Carlo , Di Trani Sabino 
Published: November 2022

AbstractMultipath cohomology is a cohomology theory for directed graphs, which is defined using the path poset. The aim of this paper is to investigate combinatorial properties of path posets and to provide computational tools for multipath cohomology. In particular, we develop acyclicity criteria and provide computations of multipath cohomology groups of oriented linear graphs. We further interpret the path poset as the face poset of a simplicial complex, and we investigate realisability problems.

AbstractThe sublingual mucosa is a commonly used intraoral location for identifying microcirculatory alterations using handheld vital microscopes (HVMs). The anatomic description of the sublingual cave and its related training have not been adequately introduced. The aim of this study was to introduce anatomy guided sublingual microcirculatory assessment. Measurements were acquired from the floor of the mouth using incident dark-field (IDF) imaging before (T0) and after (T1) sublingual cave anatomy instructed training. Instructions consists of examining a specific region of interested identified through observable anatomical structures adjacent and bilaterally to the lingual frenulum which is next to the sublingual papilla. The anatomical location called the sublingual triangle, was identified as stationed between the lingual frenulum, the sublingual fold and ventrally to the tongue. Small, large, and total vessel density datasets (SVD, LVD and TVD respectively) obtained by non-instructed and instructed measurements (NIN (T0) and IM (T1) respectively) were compared. Microvascular structures were analyzed, and the presence of salivary duct-related microcirculation was identified. A total of 72 video clips were used for analysis in which TVD, but not LVD and SVD, was higher in IM compared to NIM (NIM vs. IM, 25 ± 2 vs. 27 ± 3 mm/mm2 (p = 0.044), LVD NIM vs. IM: 7 ± 1 vs. 8 ± 1mm/mm2 (p = 0.092), SVD NIM vs. IM: 18 ± 2 vs. 20 ± 3 mm/mm2 (p = 0.103)). IM resulted in microcirculatory assessments which included morphological properties such as capillaries, venules and arterioles, without salivary duct-associated microcirculation. The sublingual triangle identified in this study showed consistent network-based microcirculation, without interference from microcirculation associated with specialized anatomic structures. These findings suggest that the sublingual triangle, an anatomy guided location, yielded sublingual based measurements that conforms with international guidelines. IM showed higher TVD values, and future studies are needed with larger sample sizes to prove differences in microcirculatory parameters.

Abstract
There is a large amount of research that indicates that the use of 3DMP in STEM education improves students’ knowledge, motivation, and participation in the learning process. Nevertheless, despite the existing attempts to market 3DMP in education, its adoption in schools remains low. A number of studies with teachers in secondary schools and colleges indicate that teachers’ perceptions of 3DMP are one of the key factors for its successful use. However, to our best knowledge, there is no research that examined STEM upper primary school teachers’ perception on 3DMP. Through phenomenographic approach, this study is seeking to address the existing gaps. Four conceptions of 3DMP teaching emerged: (1) 3DMP as tools for classroom modernization; (2) 3DMP technical and software characteristics’ impact on implementation; (3) 3DMP as a tool for learning and improvement in teaching; (4) 3DMP and students’ professional orientation, teachers’ professional development. These four categories are connected by five key aspects of variation: impact on students, impact on teachers, classroom activity management, authenticity, subject-curriculum matters. The results of our study indicate that the mathematics and science teachers have a more sophisticated opinion on 3DMP than teachers of technical education, engineering, and informatics who mostly require additional training when it comes to using 3DMP in STEM education. Comparatively, science and mathematics teachers need support with implementation of software and 3D printers as a technical tool. Considering that this study’s teachers were early adopters of 3DMP, any future research should explore conceptions of experienced users.
Challenging the Rule of Law Universalism: Why Marxist Legal Thought Still Matters
Authors: Piekarska Anna 
Published: November 2022

AbstractThe primary aim of this article is to present the rule of law universalism as a relevant theoretical and socio-political issue that critical legal thought needs to contend with. In order to do so, this issue is described through a Marxist theoretical framework, which aids in identifying the consequences of this universalism. Furthermore, the Marxist theoretical framework is suggested as a countermeasure that allows for going beyond it. The rule of law universalism is analysed as a process connected to establishing hegemony and status quo that affects both the way the law is thought of and practiced. The post-communist context serves in fleshing out some of these consequences. Although the transition is not the main subject of inquiry, it is a starting point to a set of philosophical questions directed towards the rule of law universalism, mainly regarding historical embeddedness and socio-political dependency of the rule of law. The transitional context illustrates the tension between the rule of law treated as a generalized blueprint and the reality it is introduced to. The method of approach to this tension argued for in this paper is Marxian theorization of concept as an interplay between concrete and abstract that underlies historical materialism. This movement within concept is juxtaposed to the universalism. The philosophical investigations are followed by findings from Marxist legal theory that pinpoint the importance of concrete interventions into the legal theory that abate its ever-growing abstractness. In particular, the import of knowledges and practices divorced from the capitalist system is brought into focus. The paper concludes with a brief assessment of the possibility of overturning the rule of law universalism and a discussion on the emancipatory potential of law.

Abstract
Purpose
Shorter hypofractionated radiation therapy (HF-RT) schedules may have radiobiological, patient convenience and healthcare resource advantages over conventionally fractionated radiation therapy (CF-RT) in glioblastoma (GBM). We report outcomes of young, fit GBM patients treated with HF-RT and CF-RT during the COVID-19 pandemic, and a meta-analysis of HF-RT literature in this patient subgroup.

Methods
Hospital records of patients with IDH-wildtype GBM treated with HF-RT (50 Gy/20 fractions) and CF-RT (60 Gy/30 fractions) between January 2020 and September 2021 were reviewed. Overall survival (OS) and progression-free survival (PFS) were estimated using the Kaplan-Meier method. Univariable analysis was performed using Cox regression analysis. A systematic search and meta-analysis of studies from January 2000 to January 2022 was performed.

Results
41 patients were treated (HF-RT:15, CF-RT:26). For both HF-RT and CF-RT groups, median age was 58 years and 80–90% were ECOG 0–1. There were more methylated tumours in the HF-RT group. All patients received concurrent/adjuvant temozolomide. At 19.2 months median follow-up, median OS was 19.8 months and not-reached for HF-RT and CF-RT (p = 0.5), and median PFS was 7.7 and 5.8 months, respectively (p = 0.8). HF-RT or CF-RT did not influence OS/PFS on univariable analysis. Grade 3 radionecrosis rate was 6.7% and 7.7%, respectively. 15 of 1135 studies screened from a systematic search were eligible for meta-analysis. For studies involving temozolomide, pooled median OS and PFS with HF-RT were 17.5 and 9.9 months (927 and 862 patients). Studies using shortened HF-RT schedules reported 0–2% Grade 3 radionecrosis rates.

Conclusion
HF-RT may offer equivalent outcomes and reduce treatment burden compared to CF-RT in young, fit GBM patients.
Transforming East Asia: Regional Integration in a Trade War Era
Authors: Jackson Karen , Shepotylo Oleksandr 
Published: November 2022

AbstractThis paper evaluates the trade and welfare implications of further East Asian trade integration, through the signing of the China-Japan-Korea FTA, and continued trade tensions between the US and China. Our analysis uses a structural gravity approach to explore the effects of these cooperative and non-cooperative trade policies. Our key findings are: (i) for China, the FTA can compensate for continued trade tensions (ii) in terms of the FTA and for the members involved, reductions in tariffs are expected to lead to larger welfare gains compared to those from lower NTBs (iii) for the members involved, a deeper agreement will be more welfare enhancing. Overall, East Asian integration appears to be a more appealing prospect in light of tensions with the US.

Published: November 2022

AbstractRide-hailing services such as Lyft, Uber, and Cabify operate through smartphone apps and are a popular and growing mobility option in cities around the world. These companies can adjust their fares in real time using dynamic algorithms to balance the needs of drivers and riders, but it is still scarcely known how prices evolve at any given time. This research analyzes ride-hailing fares before and during the COVID-19 pandemic, focusing on applications of time series forecasting and machine learning models that may be useful for transport policy purposes. The Lyft Application Programming Interface was used to collect data on Lyft ride supply in Atlanta and Boston over 2 years (2019 and 2020). The Facebook Prophet model was used for long-term prediction to analyze the trends and global evolution of Lyft fares, while the Random Forest model was used for short-term prediction of ride-hailing fares. The results indicate that ride-hailing fares are affected during the COVID-19 pandemic, with values in the year 2020 being lower than those predicted by the models. The effects of fare peaks, uncontrollable events, and the impact of COVID-19 cases are also investigated. This study comes up with crucial policy recommendations for the ride-hailing market to better understand, regulate and integrate these services.
Spatial variability of soil properties, nitrogen balance and nitrate leaching using digital methods on heterogeneous arable fields in southern Germany

Published: November 2022

AbstractIn this study, the spatial variability of nitrogen (N) balances and potential nitrate leaching were determined in heterogeneous arable fields in southern Germany using digital methods (tractor-mounted multispectral sensor, satellite data, vegetation indices and models) and measurements of nitrate stocks in deeper zones (1−2.5 m soil depth) with deep drilling. The aim of this study was to achieve precise localisation of N losses at high spatial resolution (sub field level; 10 × 10 m grid). The spatial variability of plant parameters within uniformly fertilised fields (crop yield, N uptake) was determined for the calculation of the N balances. The spatial variability of soil properties (e.g. soil organic carbon content, soil total nitrogen content) were determined to identify the causes of high or low N surpluses and nitrate leaching in sub-fields. N surplus determined using different digital methods and measured nitrate stocks showed similar spatial patterns. Site-specific N balancing identified zones with high N loss potential (N surplus up to 86 kg ha−1). Deep drilling showed zones with high nitrate loss (nitrate N up to 94 kg ha−1). N surplus and nitrate loss correlated with r = 0.49. This relationship could be impacted by many other soil and management factors. Soil properties showed considerable spatial variation within the fields. Soil organic carbon (SOC) and soil total nitrogen (TN) content were closely correlated in all fields (up to r = 0.96) and were most closely positively correlated with crop yield and N uptake (up to r = 0.74) and negatively correlated with N surplus (up to r = − 0.73). The sensor data and satellite data (crop yield, N uptake, N surplus) showed similar distribution patterns. Based on these results, digital technologies are suitable for the calculation of site-specific N surplus and estimation of nitrate leaching risk. Satellite or sensor based site-specific and yield-oriented fertilization is one approach to reduce N surplus on sub fields with low yield potential and high nitrate leaching risk.

AbstractWe develop heuristic interpolation methods for the functions$$t\mapsto \log \det \left( \textbf{A} + t\textbf{B} \right) $$t↦logdetA+tBand$$t\mapsto {{\,\textrm{trace}\,}}\left( (\textbf{A} + t\textbf{B})^{p} \right) $$t↦trace(A+tB)pwhere the matrices$$\textbf{A}$$Aand$$\textbf{B}$$Bare Hermitian and positive (semi) definite and$$p$$pand$$t$$tare real variables. These functions are featured in many applications in statistics, machine learning, and computational physics. The presented interpolation functions are based on the modification of sharp bounds for these functions. We demonstrate the accuracy and performance of the proposed method with numerical examples, namely, the marginal maximum likelihood estimation for Gaussian process regression and the estimation of the regularization parameter of ridge regression with the generalized cross-validation method.
