description: This poster outlines the design of a new survey created by the Digital Preservation at Oxford and Cambridge (DPOC) project, in collaboration with the Digital Preservation Coalition (DPC). The purpose of the survey is to collect current statistics about full-time equivalent (FTE) staffing resources that organizations have dedicated to digital preservation activities, and how these FTEs are arranged in each organization. This will be measured alongside each organization’s current digital preservation maturity level, the duration the organization has been undertaking digital preservation activities and their current digital preservation policy and strategy landscape. The intention is to provide up-to-date and accurate information for organizations looking to build their own business cases and advocate for digital preservation programs.

How Well Do Cognitive and Metacognitive Models Predict Obsessive-Compulsive Symptoms?
Creators: name: Nance, Melissa
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: The research reported here was designed to expand upon the understanding that cognitive and metacognitive theories each offer explanations for the development of obsessive compulsive disorder (OCD) by contrasting predictions derived from these models. Undergraduate students at the University of North Carolina at Chapel Hill (n=110) completed online surveys to facilitate this study. The Obsessive Beliefs Questionnaire (OBQ-44) was used to measure beliefs and appraisals which are considered to be critical to the etiology of OCD from the cognitive perspective, whereas the Metacognitive Beliefs Questionnaire (MCQ-30) was used to measure beliefs related to monitoring and evaluating thoughts, from the metacognitive perspective. Each of these models has support in that both cognitive and metacognitive beliefs are linked to OC symptoms, but the extent to which the OBQ and MCQ account for various obsessive-compulsive (OC) symptoms had not been compared previously. Partial correlations and hierarchical regression analyses provided a framework through which to compare the utility of these tools in predicting OC symptoms, while holding general distress constant. In final regression models the OBQ significantly predicted OC symptoms related to responsibility for harm whereas the MCQ significantly predicted OC symptoms related to unacceptable thoughts and symmetry. Neither the OBQ nor the MCQ significantly predicted OC contamination concerns in this study, however, across regression models the MCQ and OBQ differed in the amount of variance in OC symptoms that they could each explain. These findings demonstrate a lack of overlap between the OBQ (specifically the importance and control of thoughts domain) and the MCQ, as previously suggested. This study offers additional insight into how cognitive and metacognitive models align with various OC symptom domains, and indicates that each model has specific strengths in predicting certain kinds of OC symptoms.

description: In this paper, we aim to address the problem of channel robustness in speech countermeasure (CM) systems, which are used to distinguish synthetic speech from human natural speech. On the basis of two hypotheses, we suggest an approach for perturbing phase information during the training of time-domain CM systems. Communication networks often employ lossy compression codec that encodes only magnitude information, therefore heavily altering phase information. Also, state-of-the-art CM systems rely on phase information to identify spoofed speech. Thus, we believe the information loss in the phase domain induced by lossy compression codec degrades the performance of the unseen channel. We first establish the dependence of time-domain CM systems on phase information by perturbing phase in evaluation, showing strong degradation. Then, we demonstrated that perturbing phase during training leads to a significant performance improvement, whereas perturbing magnitude leads to further degradation.

Publisher: name: Culture - Journal of Culture in Tourism, Art & Education
Year: 2023

description: This article briefly approaches the multidimensional character of press, and especially of newspapers, as a means of communication used not only for transmission but also for mediation of the events. Press, considered as a cultural product, facilitates both the historical understanding of social relations and the mass’ way of thinking. A two-way communicative relationship is gradually being built, which is fed back by the needs of the press. The issues of press are related to society, which interacts in a way with it. In this sense, considering the contribution of the Press can facilitate the terms of understanding the social and educational context. In this way, the testimonies in this context intersect based on the assessment of constant or changing conditions. Methodologically, our effort utilizes theoretical approaches in order to define the function of this means of communication.

Motion of small objects in curved spacetimes: An introduction to gravitational self-force
Creators: name: Pound, Adam
Publisher: name: arXiv
Year: 2015
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: In recent years, asymptotic approximation schemes have been developed to describe the motion of a small compact object through a vacuum background to any order in perturbation theory. The schemes are based on rigorous methods of matched asymptotic expansions, which account for the object's finite size, require no "regularization" of divergent quantities, and are valid for strong fields and relativistic speeds. Up to couplings of the object's multipole moments to the external background curvature, these schemes have established that at least through second order in perturbation theory, the object's motion satisfies a generalized equivalence principle: it moves on a geodesic of a certain smooth metric satisfying the vacuum Einstein equation. I describe the foundations of this result, particularly focusing on the fundamental notion of how a small object's motion is represented in perturbation theory. The three common representations of perturbed motion are (i) the "Gralla-Wald" description in terms of small deviations from a reference geodesic, (ii) the "self-consistent" description in terms of a worldline that obeys a self-accelerated equation of motion, and (iii) the "osculating geodesics" description, which utilizes both (i) and (ii). Because of the coordinate freedom in general relativity, any coordinate description of motion in perturbation theory is intimately related to the theory's gauge freedom. In this review I describe asymptotic solutions of the Einstein equations adapted to each of the three representations of motion, and I discuss the gauge freedom associated with each. I conclude with a discussion of how gauge freedom must be refined in the context of long-term dynamics.

Year: 2016

description: This study observes global and local processing in 3½ year old children to understand
developmental trajectories at this age, and explores correlations of global and local processing to
ASD risk. Participants were selected at 12 months old based on their successful completion of
the FYI (First Year Inventory), a parent questionnaire that assesses early risk for ASD. Twenty-nine
typically-developing 3½ year olds performed a forced choice Navon shape task, in which
they were presented with shapes that contained both local and global levels, and then two shapes
at either the local or global level. They were instructed to choose which one they saw first.
Higher global scores were slightly correlated to higher risk scores from the FYI. These results
are discussed in the context of global and local processing in ASD groups and typically-developing
groups.

description: Gravitational waves (GW) emanating from unstable quasi-normal modes in Neutron Stars (NS) could be accessible with the improved sensitivity of the current GW detectors or with the next-generation GW detectors and, therefore, can be employed to study the NS interior. Assuming f-mode excitation in isolated pulsars with typical energy of pulsar glitches and considering potential f-mode GW candidates for A+ (upgraded LIGO detectors operating at 5th observation run design sensitivity) and Einstein Telescope (ET), we demonstrate the inverse problem of NS asteroseismology within a Bayesian formalism to constrain the nuclear parameters and NS Equation of State (EOS). We describe the NS interior within relativistic mean field formalism. Taking the example of glitching pulsars, we find that for a single event in A+ and ET, among the nuclear parameters, the nucleon effective mass ($m^*$) within 90\% credible interval (CI) can be restricted within $10\%$ and $5\%$, respectively. At the same time, the incompressibility ($K$) and the slope of the symmetry energy ($L$) are only loosely constrained. Considering multiple (10) events in A+ and ET, all the nuclear parameters are well constrained, especially $m^*$, which can be constrained to 3\% and 2\% in A+ and ET, respectively. Uncertainty in the observables of a $1.4M_{\odot}$ NS such as radius ($R_{1.4M_{\odot}}$), f-mode frequency ($f_{1.4M_{\odot}}$), damping time ($τ_{1.4M_{\odot}}$) and a few EOS properties including squared speed of sound ($c_s^2$) are also estimated.

description: A format is created, becomes widely used, and eventually fades away. File format obsolescence lies at the core of many digital preservation narratives, but does the field know what obsolescence looks like. This demonstration explores the issue of obsolescence with tools that can be used to see the rise and fall of formats in an institution’s collection and potentially distinguish a local extirpation from a mass extinction. By demonstrating the information about format endangerment that can be derived and the tools used to derived it, this demonstration aims to encourage a practice of sharing file format profiles of collections that can be used to better understand the lifecycles of file formats and inform better format management practices.

description: Purpose: As consumer debt can substantially impair subjective well-being, it is crucial for research to gain insights into how consumers can be motivated to improve financial planning. This paper aims to investigate how frontline employees in financial services can help consumers regulate their financial planning behaviors and how financial service providers can effectively support their frontline employees in this effort through leadership and organizational climate. Design/methodology/approach: We incorporate regulatory focus theory and conservation of resource theory to develop a conceptual model that we test in a triadic study with a unique dataset collected from consumers, frontline employees, and managers in the banking sector. Findings: We find that frontline employees must pay attention to the details of consumers’ needs and customize the service to those needs to trigger consumer promotion focus and stimulate consumers’ financial planning behaviors. Moreover, our results emphasize that the organization must act as an integrated entity. Thus, a manager’s servant leadership and an organizational climate of customer stewardship are crucial for frontline employees to transform consumers’ financial planning behaviors. Research limitations/implications The study highlights frontline employees’ key role in motivating consumer financial planning behavior, offering a new perspective in transformative service research on enhancing financial well-being. Practical implications: The findings provide financial service providers with actionable implications for enhancing consumers’ financial planning. This benefits both consumers and financial institutions, as customers with greater spending power can buy more financial products. Originality/value: This study advances transformative service research on consumer financial planning behavior, which has largely focused on consumer-related or society-level variables, by exploring the role of frontline employees and organizational support in terms of leadership and climate.

description: Measurements of the primordial element abundances provide us with an important probe of our universe's early thermal history, allowing us to constrain the expansion rate and composition of our universe as early as $\sim 1 \, {\rm s}$ after the Big Bang. Prior to this time, we have essentially no empirical information on which to base any such claims. In this paper, we imagine a future time in which we have not only detected the particles that make up the dark matter, but have measured their mass and annihilation cross section with reasonable precision. In analogy to the light element abundances, the dark matter abundance in this scenario could be used to study and constrain the expansion rate and composition of our universe at the time of dark matter freeze out, which for a standard thermal relic occurs at $T_f \sim m_χ/20$, corresponding to $t \sim 4 \times 10^{-10} \, {\rm s} \times ({\rm TeV}/m_χ)^2$, many orders of magnitude prior to the onset of Big Bang nucleosynthesis. As examples, we consider how such measurements could be used to constrain scenarios which feature exotic forms of radiation or matter, a ultralight scalar, or modifications to gravity, each of which have the potential to be much more powerfully probed with dark matter than with the light element abundances.

description: The Doppler effect, the shift in the frequency of sound due to motion, is present in both classical gases and quantum superfluids. Here, we perform an in-situ, minimally destructive measurement, of the persistent current in a ring-shaped, superfluid Bose-Einstein condensate using the Doppler effect. Phonon modes generated in this condensate have their frequencies Doppler shifted by a persistent current. This frequency shift will cause a standing-wave phonon mode to be "dragged" along with the persistent current. By measuring this precession, one can extract the background flow velocity. This technique will find utility in experiments where the winding number is important, such as in emerging `atomtronic' devices.

description: In this paper we investigate higher-order corrections to the energies of bound states in hydrogen subjected to the external blackbody radiation field. In particular, within the framework of thermal quantum electrodynamics and $S$-matrix approach we analyze combined type of two-loop self-energy corrections, including one zero-vacuum and one loop at finite temperature. By utilizing the method of dimensional regularization, we derive closed analytical expressions for the energy shifts of atomic levels. Our numerical calculations demonstrate that even at room temperature these corrections can be significant for excited states, reaching the magnitude of the thermal induced Stark contribution.

description: We describe a concept of digital preservation for smaller cultural heritage institutions without their own infrastructure. The concept is based on the Outer-Inner OAIS (OO-IO) Model. It means that a digital depot is extended by an external pre-ingest component - the aggregator. That component will serve as a multi-mode platform. The modes are (1) management, (2) gateway and (3) access. Mode 2 prepares the data for a standardized and automated ingest process. The aggregator will include web-tools and a support desk.
Human-Like Intuitive Behavior and Reasoning Biases Emerged in Language Models -- and Disappeared in GPT-4

description: Large language models (LLMs) are currently at the forefront of intertwining AI systems with human communication and everyday life. Therefore, it is of great importance to evaluate their emerging abilities. In this study, we show that LLMs, most notably GPT-3, exhibit behavior that strikingly resembles human-like intuition -- and the cognitive errors that come with it. However, LLMs with higher cognitive capabilities, in particular ChatGPT and GPT-4, learned to avoid succumbing to these errors and perform in a hyperrational manner. For our experiments, we probe LLMs with the Cognitive Reflection Test (CRT) as well as semantic illusions that were originally designed to investigate intuitive decision-making in humans. Moreover, we probe how sturdy the inclination for intuitive-like decision-making is. Our study demonstrates that investigating LLMs with methods from psychology has the potential to reveal otherwise unknown emergent traits.

description: Current digital preservation systems such as Archivematica and Preservica lack a common and consistent way to describe and execute preservation policies and actions at a technical level. Archivematica’s Format Policy Register (FPR) and Preservica’s Linked Data Registry (LDR) both define what tools and rules to use when doing digital preservation and whilst these two approaches aim to solve similar problems, they are not interoperable. There is no way to share technical information between the two solutions and for users to share their experience on what approaches to use in different contexts and why. This hinders implementation and execution of digital preservation in an interoperable way within the digital preservation community. This paper presents new work by Artefactual, Arkivum, Preservica and Jisc on how Preservation Action Registries (PAR) could be used to capture and share technical best practice for the preservation of digital objects in the form of a corpus of machine-readable recommendations. The registry’s data model defines what tools can be used for different digital object formats, what properties can be extracted or measured and what preservation actions can be taken. The model includes contextual and historical information on the reasons why recommendations are being given. The information is versioned and includes the tool parameters and software environments needed to execute different preservation actions so they are directly ‘executable’ by preservation systems. Our model makes registry content accessible through APIs using a distributed set of registries rather than a single canonical source. In this way, information can be made available from a range of sources including central registries (moderated and curated) or by exchange directly between trusted peer institutions or systems. Preservation systems such as Archivematica and Preservica are able to publish to and consume content from these registries. The work is supported by Jisc as part of the Research Data Shared Service initiative and we believe is the first time that vendors, national service providers and end-users have all come together in this way. The PAR approach should engender greater confidence in digital preservation, provide users with more flexibility and knowledge sharing opportunities, and accelerate the adoption of digital preservation in new sectors.

description: We describe the Quantum Test of the Equivalence principle and Space Time (QTEST), a concept for an atom interferometry mission on the International Space Station (ISS). The primary science objective of the mission is a test of Einstein's equivalence principle with two rubidium isotope gases at a precision of better than 10$^{-15}$. Distinct from the classical tests is the use of quantum wave packets and their expected large spatial separation in the QTEST experiment. This dual species atom interferometer experiment will also be sensitive to time-dependent equivalence principle violations that would be signatures for ultralight dark-matter particles. In addition, QTEST will be able to perform photon recoil measurements to better than 10$^{-11}$ precision. This improves upon terrestrial experiments by a factor of 100, enabling an accurate test of the standard model of particle physics and contributing to mass measurement, in the proposed new international system of units (SI), with significantly improved precision. The predicted high measurement precision of QTEST comes from the microgravity environment on ISS, offering extended free fall times in a well-controlled environment. Suppression of systematic errors by use of symmetric interferometer configurations and rejection of common-mode errors drives the QTEST design. It uses Bragg interferometry with a single laser beam at the "magic" wavelength, where the two isotopes have the same polarizability, for mitigating sensitivities to vibrations and laser noise, imaging detection for correcting cloud initial conditions and maintaining contrast, modulation of the atomic hyperfine states for reduced sensitivity to magnetic field gradients, two source regions for simultaneous time reversal measurements and redundancy, and modulation of the gravity vector using a rotating platform to reduce otherwise difficult systematics to below 10$^{-16}$.
Strengths and Growth Opportunities of a Grocery Program Serving the Homebound, Low-income, Older Adults of Apex, North Carolina:  A Program Evaluation from the Client and Volunteer Perspective
Creators: name: Ghan, Natalia

description: Functionally-disabled older adults in America, and especially those who live alone, are more likely to be food insecure.  Although there are a number of nonprofit meal delivery programs across the nation that have been shown to improve the nutritional status and provide other health benefits to the seniors they serve, some gaps in food quality and quantity persist in these programs.  Therefore, it is important that regular program evaluations are conducted in order to help ensure satisfaction and identify any unmet needs.  The purpose of this exploratory program evaluation is to holistically assess and provide recommendations to a nonprofit home food delivery program located in Apex, North Carolina.  Clients (n=6) were interviewed and volunteers (n=6) were surveyed.  Overall, clients and volunteers were extremely satisfied with the program, and clients indicated that this program is very helpful in allowing them to obtain the food they need.  This program also supports social health, evidenced by clients and volunteers citing the value of friendships formed through social interaction at delivery time.  If resources allow, there is room for growth in providing clients with fresher food and vegetables, and the option to call in for extra food supplementation when needed.  In addition, volunteers should periodically assess clients’ functional ability to prepare their own meals, and refer them to a Meals on Wheels program if necessary.  From the volunteer perspective, room for growth mainly centered on efficiency and training.  Program staff and volunteers should continue to meet to identify concerns as they arise.

description: Σύμφωνα με έρευνες, ένας στους τέσσερις θανάτους από τον κορωνοϊό της Covid-19 αφήνει πίσω του ένα παιδί που πενθεί. Καμία κρίση στην πρόσφατη μνήμη δεν προκάλεσε τόση απώλεια σε τόσο σύντομο χρονικό διάστημα. Ακόμη και υπό κανονικές συνθήκες, ο θάνατος προκαλεί πολλά συναισθήματα, αλλά οι καταστάσεις είναι τελείως διαφορετικές, όταν ένα παιδί έρχεται αντιμέτωπο με την έννοια της απώλειας και του πένθους. Στην προσχολική ή σχολική ηλικία, η απώλεια ενός κοντινού προσώπου μπορεί να έχει απήχηση σε κάθε πτυχή της ζωής τους. Ιδιαίτερα, όμως, κατά τη διάρκεια μιας πανδημίας, η απώλεια που προκαλείται από έναν νέο και τρομακτικό ιό ανατρέπει κάθε πτυχή της καθημερινής ζωής και μπορεί να εντείνει όλα αυτά τα συναισθήματα. Δεν υπάρχει ένας αποκλειστικά ενδεδειγμένος τρόπος, με τον οποίο τα παιδιά θα πρέπει να βιώσουν τη θλίψη τους, ούτε και ένας σωστός τρόπος για να προσφέρουμε υποστήριξη. Η αντιμετώπιση της απώλειας που έχουν βιώσει –και συνεχίζουν να βιώνουν– αυτά τα παιδιά, θα πρέπει να εξετάζεται στο πλαίσιο της γνωστικής, συναισθηματικής και κοινωνικής ανάπτυξής τους. Εμείς, ως ενήλικοι, θα πρέπει να καταβάλλουμε κάθε δυνατή προσπάθεια, ώστε να διασφαλίσουμε ότι θα έχουν πρόσβαση σε εμπειρικά τεκμηριωμένης καταλληλότητας παρεμβάσεις πρόληψης, που μπορούν να τα βοηθήσουν να αντιμετωπίσουν αυτό το τραύμα και να υποστηρίξουν τη μελλοντική ψυχική τους υγεία και ευημερία.

description: Surface properties are critical to the capabilities of superconducting microwave devices. The native oxide of niobium-based devices is thought to consist of a thin normal conducting layer. To improve understanding on the importance of this layer, an attempt was made to replace it with a more easily controlled gold film. A niobium sample host microwave cavity was used to measure the surface resistance in continuous wave operation at 4.0 GHz and 5.2 GHz. Sample conditions studied include temperatures ranging from 1.6 K to 4.2 K with RF magnetic fields on the sample surface ranging from 1 mT to the maximum field before the superconducting properties were lost (quench field). The nominal film thickness of the gold layer was increased from 0.1 nm to 2.0 nm in five steps to study the impact of the normal layer thickness on surface resistance on a single niobium substrate. The 0.1 nm film was found to reduce the surface resistance of the sample and to enhance the quench field. With the exception of the final step from a 1.5 nm gold film to 2.0 nm, the magnitude of the surface resistance increased substantially with gold film thickness. The nature of the surface resistance field-dependence appeared to be roughly independent from the gold layer thickness. This initial study provides new perspectives and suggests avenues for optimizing and designing surfaces for resonant cavities in particle accelerators and quantum information applications.

description: It is shown that the extended quadratic residue code of length 20 over GF(7) is a unique self-dual [20,10,9] code C such that the lattice obtained from C by Construction A is isomorphic to the 20-dimensional unimodular lattice D_{20}^+, up to equivalence. This is done by converting the classification of such self-dual codes to that of skew-Hadamard matrices of order 20.

description: Σύμφωνα με νεότερες έρευνες, η δημιουργία ενός θετικού κλίματος στις σχολικές μονάδες και η ενίσχυση της ψυχικής υγείας των εμπλεκόμενων στην εκπαιδευτική διαδικασία είναι απαραίτητα για την πρόοδο και εξέλιξη της σχολικής μονάδας. Αναδεικνύεται με πολλούς τρόπους ο ρόλος, λοιπόν, της συναισθηματικής νοημοσύνης στην αποτελεσματική και σωστή λειτουργία των μονάδων (Αρβανιτάκης, 2005). Στην παρούσα μελέτη, αναγνωρίζονται από τους εκπαιδευτικούς συγκεκριμένες δεξιότητες στη στάση και στη συμπεριφορά των διευθυντών των σχολείων τους, που σκιαγραφούν τη συναισθηματική νοημοσύνη, δίνοντας έμφαση στον πρώτο παράγοντα νοημοσύνης που αφορά το ενδοπροσωπικό κομμάτι των δεξιοτήτων τους. Η έρευνα και τα αποτελέσματα προήλθαν από το πακέτο SPSS και αναδείχθηκε ότι οι περισσότεροι εκπαιδευτικοί διακρίνουν στους διευθυντές τους τον παράγοντα της αυτοεκτίμησης, κυρίως, των προσωπικών τους συναισθημάτων και όχι της αναγνώρισης των άλλων (Καφέτσιος, 2003). Εντοπίζεται η τάση να ενισχύουν κυρίως τις δικές τους βλέψεις, έχοντας προσωπικές αξίες και να επιζητούν, κατά κύριο λόγο, την εργασιακή αναγνώριση.

description: Διεθνώς, στις υψηλές βαθμίδες της διοικητικής ιεραρχίας δημόσιων και ιδιωτικών οργανισμών, παρατηρείται μειωμένη εκπροσώπηση του γυναικείου φύλου. Ειδικότερα, στον τομέα της εκπαίδευσης, παρόλο που «γυναικοκρατείται» στο επίπεδο της Πρωτοβάθμιας και της «κατώτερης» Δευτεροβάθμιας Εκπαίδευσης (Γυμνάσιο), αυτό δεν συνεπάγεται και την ισότιμη αντιπροσώπευσή τους σε θέσεις που συνεπάγονται υψηλό κύρος και ευθύνη. Στη χώρα μας, κατά τη διάρκεια των τελευταίων δεκαετιών, παρατηρείται αυξημένη συμμετοχή των γυναικών που καταλαμβάνουν θέσεις στη διοίκηση της εκπαίδευσης, ωστόσο, ο αριθμός αυτός συνεχίζει να παραμένει χαμηλός, ιδιαίτερα όσο ανερχόμαστε στην κλίμακα της διοικητικής ιεραρχίας, υποδηλώνοντας ότι οι γυναίκες αντιμετωπίζουν μια «γυάλινη οροφή» που τις εμποδίζει στην επαγγελματική τους ανέλιξη. Σκοπός της παρούσας εργασίας είναι να προσεγγίσει θεωρητικά μέσα από τη βιβλιογραφική ανασκόπηση, την ιστορική πορεία των γυναικών στην εκπαίδευση, καθώς και την ερμηνεία των παραγόντων και των μηχανισμών που επηρεάζουν και τις παρεμποδίζουν στη διεκδίκηση ή μη, της ισότιμης συμμετοχής τους, τόσο στη διοίκηση δημοσίων και ιδιωτικών οργανισμών και εταιρειών, ειδικότερα δε στην ηγεσία της εκπαίδευσης.

description: The recent observations from the James Webb Space Telescope have led to a surprising discovery of a significant density of massive galaxies with masses of $M \ge 10^{10.5} M_{\odot}$ at redshifts of approximately $z\sim 10$. This corresponds to a stellar mass density of roughly $ρ_*\sim 10^6 M_{\odot} Mpc^{-3}$. Despite making conservative assumptions regarding galaxy formation, this finding may not be compatible with the standard $Λ$CDM cosmology that is favored by observations of CMB Anisotropies from the Planck satellite. In this paper, we confirm the substantial discrepancy with Planck's results within the $Λ$CDM framework. Assuming a value of $ε=0.2$ for the efficiency of converting baryons into stars, we indeed find that the $Λ$CDM model is excluded at more than $99.7 \%$ confidence level (C.L.). An even more significant exclusion is found for $ε\sim 0.1$, while a better agreement, but still in tension at more than $95 \%$, is obtained for $ε=0.32$. This tension, as already discussed in the literature, could arise either from systematics in the JWST measurements or from new physics. Here, as a last-ditch effort, we point out that disregarding the large angular scale polarization obtained by Planck, which allows for significantly larger values of the matter clustering parameter $σ_8$, could lead to better agreement between Planck and JWST within the $Λ$CDM framework. Interestingly, the model compatible with Planck temperature-only data and JWST observation also favors a higher Hubble constant $H_0=69.0\pm1.1$ km/s/Mpc at $68\%$ C.L., in better agreement with observations based on SN-Ia luminosity distances.

The Impact of Abortion Policy on Patient Safety: How Is It Measured?

description: In 1973, the Supreme Court decision Roe vs. Wade established the constitutional right to abortion, but since 2010, the number of abortion laws has increased significantly.  The impact of those laws on society has been conceptualized and evaluated in a variety of ways, but their impact on patient health remains obscure.
The purpose of this research is to examine measures that could be used to evaluate the impact of abortion policy on patient safety. The methodology used in this project was Bardach’s “eight-fold path” for conducting a policy analysis. A literature review was performed to identify measures from 20 studies evaluating the association between abortion policy and patient safety. Four common measures were identified: abortion fatality rate, abortion rate, unintended pregnancy/birth rate, and delay in abortion timing. Each measure was systemically evaluated based on two criteria: (1) relevance and validity as a measure of patient safety and (2) convenience. The most relevant and valid measure was delay in abortion timing.  While collecting data about abortion timing is inconvenient and costly, it may be worthwhile as long as the concept of “safety” is prominent in the political discourse around abortion and valid evidence for policy-making is desired. The first step toward evidence-based public policy is ensuring the use of valid, relevant measures.
