Assessing Spatiotemporal Behavior of Human Gait: A Comparative Study Between Low-Cost Smartphone-Based Mocap and OptiTrack Systems
Authors: Castillo B. , Riascos C. , Franco J. M. , Marulanda J. , Thomson P. 
Published: May 2024

Abstract
This study assessed the accuracy of a low-cost marker-based motion capture system with smartphone devices to estimate the spatiotemporal behavior of human gait in comparison with the performance of the commercial OptiTrack system. Initially, three test subjects were selected for the study, and after equipping them with passive retroreflective markers, they were recorded for gait velocities of 1.50, 1.90, and 2.30

while collecting kinematic data and videos. The results showed that the smartphone motion capture system exhibited significant spatiotemporal tracking and accuracy in the x-y trajectories and estimation of joint relative angles of the hip, knee, and ankle joints (θ1, θ2, and θ3, respectively) compared to the commercial OptiTrack system. In this comparison, an average goodness-of-FIT and normalized root mean square error of over 88.93% and 2.71% were obtained, respectively, for the joint relative angles of the hip and knee (θ1 and θ2) in all tests performed. However, the accuracy of the joint relative angle of the ankle (θ3, average FIT: 71.04% and nRMSE: 4.26%) was lower because of the low capture rate of the retroreflective markers in the smartphone system and the higher relative velocity in the lower extremities of the test subjects, which generated noise in the calculation of x-y trajectories. This decrease in accuracy has been reported in other studies. However, both motion capture systems experienced marker data loss at the hip, highlighting the need for improvement in the spatial distribution of the optical devices. The OptiTrack system demonstrated better optical redundancy but still required improvements. In contrast, the smartphone system, with its inherent limitations in terms of optical redundancy and spatial distribution, can be enhanced by incorporating multiple cameras for a three-dimensional view. Despite these limitations, the low-cost smartphone system showed optimal performance with minimal errors compared with the commercial system, making it a cost-effective option with potential for further development. The rapid advancement of smartphone technology and its accessibility make it an attractive choice for motion capture applications.
Externalisation of Migration Controls: A Taxonomy of Practices and Their Implications in International and European Law
Authors: Nicolosi Salvatore Fabio 
Published: May 2024

AbstractThe externalisation of migration and border controls refers to a series of practices whereby States attempt to manage migration flows and enforce immigration policies beyond their borders, often by collaborating with other countries or non-state actors. Externalisation can involve various measures such as outsourcing border control functions, implementing agreements with neighbouring or transit countries to intercept migrants before they reach the State’s territory, and providing aid or incentives for other countries to prevent or reduce migration flows. Externalisation practices are employed to shift the burden of migration management away from the receiving state and onto other actors or territories, often to limit responsibilities and on the assumption that human rights obligations only apply territorially. In an attempt to challenge such an assumption and to frame the nature of human rights obligations in the context of externalisation practices, this article develops a taxonomy of externalisation measures and provides an overview of the jurisdictional approaches to the extraterritorial scope of human rights obligations.
A Region-Selective Anti-compression Image Encryption Algorithm Based on Deep Networks

Published: May 2024

AbstractIn recent years, related research has focused on how to safely transfer and protect the privacy of images in social network services while providing easy access by authorized users. To safeguard privacy, we suggest an image encryption scheme that combines data hiding and image encryption. The proposed scheme successfully decrypts images after JPEG compression attacks and preserves the privacy of secret regions through the use of block scrambling encryption based on region selection. Simultaneously, the scheme can handle nonuniform secret regions and obtain more sensitive secret keys because of the incorporation of a chaotic system. The enhanced deep learning-based data-hiding technology reduces algorithm complexity by enabling the encryption position to be determined in the decryption phase without the need for any information or equipment. However, this approach also increases algorithm security, because only when the right secret data are extracted can they be decrypted successfully. According to the experimental findings, the proposed scheme can correctly decrypt images via JPEG compression while maintaining visually acceptable quality. The proposed scheme can achieve greater robustness against image processing algorithms and a wider secret key space than traditional schemes.
The Primacy of the Practical
Authors: Brunero John 
Published: May 2024

AbstractAccording to Action-First theorists, like Jonathan Dancy, reasons for action explain reasons for intentions. According to Intention-First theorists, like Conor McHugh and Jonathan Way, reasons for intentions explain reasons for action. In this paper, I introduce and defend a version of the Action-First theory called “Instrumentalism.” According to Instrumentalism, just as we can derive, using principles of instrumental transmission, reasons to ψ from reasons to ϕ (provided there’s some relevant instrumental relation between ψ-ing and ϕ-ing), we can derive reasons to intend to ϕ from reasons to ϕ (provided there’s some relevant instrumental relation between intending to ϕ and ϕ-ing). After providing some defense of Instrumentalism, I turn to two recent, important arguments for the Intention-First theory advanced by McHugh and Way, and I argue that neither of them succeed. I conclude that we should reject the Intention-First theory and that we have grounds for optimism about the Action-First theory.
A crinoid fauna and a new species of Pycnocrinus from the Martinsburg Formation (Upper Ordovician), lower Hudson Valley, New York
Authors: Brower James C. , Brett Carlton E. , Feldman Howard R. 
Published: May 2024

AbstractA new crinoid fauna has been discovered in the Upper Ordovician (Katian) Martinsburg Formation at a small shale quarry, locally known as the ‘Shale Bank,’ on the Shawangunk Ridge in Ulster County, NY. The assemblage, which is from a relatively low energy, offshore mud-bottom environment, includes four identified species, including a new species of glyptocrinid camerate, Pycnocrinus mohonkensis n. sp., described herein. Crinoid taxa in order of increasing branch density in the assemblage include (1) the dicyclic inadunate Merocrinus curtus with irregularly isotomous and heterotomous, non-pinnulate arms and a stout cylindrical column exceeding 700 mm; (2) the disparids Cincinnaticrinus varibrachialus, with heterotomous non pinnulate arms, and Ectenocrinus simplex, with extensively branched ramulate arms and meric columns of 460–500 mm; and (3) the camerate Pycnocrinus mohonkensis n. sp., with uniserial pinnulate arms and a somewhat shorter column. Some cylindrical stems with nodose and holomeric columnals are thought to belong to unknown camerate crinoids with pinnulate arms. Filtration theory is used to model food capture in the Martinsburg crinoids. Surprisingly, even densely pinnulate camerates were able to survive in this setting, suggesting that ambient currents attained velocities exceeding 25 cm/sec even in this offshore setting. Similar assemblages were widespread in eastern Laurentia during the Late Ordovician.UUID: http://zoobank.org/23ca31e8-f572-4520-ba1d-891e3abb950d
Independence in Europe: Regionalist Party Rhetoric and the EU in a Post-Brexit United Kingdom
Authors: Snowmann Sarah 
Published: May 2024

AbstractIn the wake of Brexit, how has the framing of the EU and independence evolved among regionalist parties in the devolved regions of the UK? The effects of a multilevel structure such as the EU on regionalist parties has been examined, yet European disintegration is novel and thus yet to be fully explored. Has the framing of the EU by these parties shifted, and if so, how? In this article, I analyze 19 regionalist party manifestos between 2011 and 2022 through the lens of rational choice and discursive institutionalism to examine the effects of Brexit on the framing of the EU. At a rhetorical level, these parties have engaged in the subsuming of the EU, rhetorically tying their independence or enhanced autonomy to Brexit. Sinn Féin, Scottish Nationalist Party, and Plaid Cymru have used the critical juncture of Brexit to incorporate the EU into their regionalist rhetoric. By examining the effects of European disintegration on regionalist political parties, we can better understand the role that current events play in the fluidity of party positions as presented in manifestos.
Estimators for Topic-Sampling Designs
Authors: Clifford Scott , Rainey Carlisle 
Published: May 2024

AbstractWhen researchers design an experiment, they usually hold potentially relevant features of the experiment constant. We call these details the “topic” of the experiment. For example, researchers studying the impact of party cues on attitudes must inform respondents of the parties’ positions on a particular policy. In doing so, researchers implement just one of many possible designs . Clifford, Leeper, and Rainey (2023. “Generalizing Survey Experiments Using Topic Sampling: An Application to Party Cues.” Forthcoming in Political Behavior. https://doi.org/10.1007/s11109-023-09870-1) argue that researchers should implement many of the possible designs in parallel—what they call “topic sampling”—to generalize to a larger population of topics. We describe two estimators for topic-sampling designs: First, we describe a nonparametric estimator of the typical effect that is unbiased under the assumptions of the design; and second, we describe a hierarchical model that researchers can use to describe the heterogeneity. We suggest describing the heterogeneity across topics in three ways: (1) the standard deviation in treatment effects across topics, (2) the treatment effects for particular topics, and (3) how the treatment effects for particular topics vary with topic-level predictors. We evaluate the performance of the hierarchical model using the Strengthening Democracy Challenge megastudy and show that the hierarchical model works well.
Creating and Using Liturgies for the Commune sanctorum in Medieval Iberia
Authors: Hornby Emma , Jones Marcus , Shaffer Melanie 
Published: May 2024

AbstractProviding source material for liturgical practice on a significant proportion of feast days in each sanctorale cycle, the Commune sanctorum liturgies had crucial daily importance for medieval Christians. Despite their frequent use, or perhaps because of this prosaic nature, the Commune sanctorum has rarely been considered as a liturgical phenomenon in its own right. Focusing on the Old Hispanic liturgy, this article explores the creation and presentation of the Commune sanctorum. We address systematically a question left unexamined in previous scholarship: where did the Commune sanctorum come from? We first survey the Old Hispanic material shared with other rites. Turning then to the Old Hispanic rite’s unique material, we examine materials found only in the Commons and those shared elsewhere in the rite. We set out a methodology for determining the direction of origin for such shared chants, demonstrating the importance of proper saints’ liturgies in the creation of the Commune sanctorum as well as the creative interest in producing new Commons materials. In addition to the origin of the Commune sanctorum, this article engages with manuscript presentation, asking how Commons materials were organized and how such presentations guided liturgical practitioners. A deeper understanding of the Commune sanctorum opens a window onto one of the foundational devotional experiences of Western Christendom.

AbstractObjectiveTo assess the efficacy and safety of two different modes of administration, external ear canal filling and smearing, in the treatment of otomycosis.MethodsA computerised search of relevant published studies in the China National Knowledge Infrastructure, China Biology Medicine, Web of Science, PubMed, Embase and Cochrane Library databases that include randomised controlled trials or clinically controlled trials on the same drug in different modes of administration for the treatment of otomycosis.ResultsSeven studies with 934 patients were included. The filled group had a higher clinical efficacy (relative risk = 1.18, 95 per cent confidence interval (CI) 1.12–1.24, p < 0.0001) and a lower recurrence rate (relative risk = 0.29, 95 per cent CI 0.18–0.47, p < 0.0001) compared with the smear group, and there was no significant difference in the adverse effects (relative risk = 0.61, 95 per cent CI 0.34–1.12, p = 0.11).ConclusionCurrent evidence suggests that the efficacy of the delivery modality of the external auditory canal filling treatment is significantly better than external auditory canal smearing.

Published: May 2024

Abstract
Otoliths are an excellent tool for analysing the pattern of habitat use between adults and juveniles and connectivity between fish populations. Larimus breviceps is a species belonging to the family Sciaenidae, which has an important role in the marine food chain, as it is one of the most abundant and frequent species in the bycatch of coastal shrimp fisheries in Brazil. The present study aimed at comparing the otolith shape of specimens collected in three different Brazilian coastal areas: Sergipe (SE), northeastern region; São Paulo (SP), southeastern region; and Paraná (PR), southern region. In a laboratory, 88 otoliths were extracted, photographed, and the contour was analysed by the wavelet method (32 from SE, 28 from SP, and 28 from PR). The otolith contours varied between sampling sites. Linear discriminant analysis correctly reclassified 60.23% otoliths by the sampled sites, with the best reclassifications occurring in SE (62.5%), followed by PR (60.71%) and SP (57.14%). Multivariate analysis of variance also evidenced significant differences in contours among the sampling sites (F = 2.3; P < 0.005). Thus, two morphotypes of otoliths were found for L. breviceps: one from Sergipe (northeastern Brazil) and the second one from southeastern–southern Brazil, indicating connectivity between the populations off São Paulo and Paraná, to be confirmed by future genetic studies.
Philometroides giginosantoroi n. sp. (Nematoda: Philometridae), a new muscle-infecting species in the Mediterranean moray (Muraena helena) revealed using integrative taxonomy
Authors: López-Verdejo Alejandro , Occhibove Flavia , degli Uberti Barbara , Crocetta Fabio , Santoro Mario 
Published: May 2024

AbstractPhilometroides Yamaguti, 1935 is a genus of dracunculoid nematodes of the family Philometridae Baylis & Daubney, 1926 comprising tissue-infecting species worldwide. In the present study, a new species of Philometroides is described from the Tyrrhenian Sea (central-western Mediterranean Sea) using integrative approaches such as light and scanning microscopy, histopathology and 18S rRNA sequencing. Philometroides giginosantoroi n. sp. found in the skeletal muscles of the Mediterranean moray Muraena helena can be distinguished from its congeners by a combination of morphological traits and in particular by having the oral aperture with 3 large sclerotized triangular oesophageal teeth. The molecular analyses and phylogenetic reconstructions support its status as a new taxon and placed it within a clade of tissue-infecting species, although also confirmed mismatches in the generic assignment of several species. Philometroides giginosantoroi n. sp. is the second species of the genus found in the Mediterranean Sea and in general in the European marine waters and the third species of the family known to infect the family Muraenidae.
Proxy failures in practice: Examples from the sociology of science

Published: May 2024

Abstract
Following John et al., we provide examples of failing proxies that might help to contextualize the role of proxy failures in applied research. We focus on examples from the sociology of science and illustrate how the notion of proxy failure can sharpen applied analysis, if used in a way that does not obscure other dysfunctional effects of proxies.
Navigating proxy failures in education: Learning from human and animal play
Authors: Samuelsson Robin 
Published: May 2024

Abstract
The notion of proxy failure provides considerable insight into educational processes, and in childhood education has the potential to elucidate known problems stemming from the early implementation of overly regulated educational regimes. This commentary expands on play and how its relation to learning provides a useful perspective on how activities based on nongoal-oriented interactions can lead to desired outcomes.
Statistical Insignificance is not wholesale transfer in L3 Acquisition: An approximate replication of Rothman (2011)
Authors: Parrish Kyle 
Published: May 2024

AbstractThis study was an approximate replication of Rothman (2011),examining the determiner phrase syntax of a large sample (n = 211) of L3 learners of Portuguese who spoke English and Spanish. Rothman (2011) investigated whether L3 Italian or Brazilian Portuguese speakers are differently impacted by another known Romance Language, if it was their L1 or L2. The original study concluded that groups did not perform differently on experimental tasks on the basis of a null effect, and that the typological similarity of Spanish, Portuguese, or Italian predicts transfer in the initial stages of L3 acquisition. The present replication recreated all materials, which were unavailable, and examined the same population and questions. However, rather than examining L3 Italian and L3 Brazilian Portuguese, the present work maintained a constant L3 Portuguese. Learners were divided into two groups in a mirror-image design (n = 96 L1 English-L2 Spanish, n = 115 L1 Spanish-L2 English), and data were collected online. Like the original study, there was no main effect of group in any of the two-way analyses of variance. However, results show that it should not be assumed that experimental groups behave equivalently based on a null effect: Of the four total post hoc tests of equivalence, only two were significant when the equivalence bounds were set at a small effect size (d = $ \pm $ .4). Ultimately, it is argued that determining the smallest effect size of interest and subsequent equivalence testing are necessary to answer key questions in the field of L3 acquisition.
Racial Realities
Authors: Anderson Luvell 
Published: May 2024

AbstractHow should we conceive of conflicts that seem intractable? Is there any hope of a resolution? We observe impasses between various groups concerning the Israeli and Palestinian conflict, the Movement for Black Lives and racial conservatives, and Indigenous voices versus settler colonial states. Some aspects of these impasses can surely be explained by an unwillingness by one or more parties to the conflict to yield any ground. Might there also be room for misunderstanding generated by radically different ways of conceiving the world? According to the different worlds thesis, people come to radically different understandings of the world because they inhabit incompatible conceptual realities. In this article, I endeavor to explore possible ways of understanding the thesis and its potential impact on certain normative practices we tend to take for granted.
Inflammatory Language
Authors: Lepore Ernie 
Published: May 2024

AbstractThis is a paper is about a particular subclass of pejoratives, namely, slurs. These are epithets that denigrate a group on the basis of membership alone, e.g., on the basis of race, ethnicity, origin, religion, gender, or ideology. They carrry a characteristic sting, prone to cause outrage and even injury. As to the source of their characteristic sting, the predominant position invokes some aspect of meaning. Some of the few who reject this assumption locate the source of the sting in the taboo status of pejoratives. Others think slurs can sting because of negative associations they carry across time. We challenge both approaches and defend an alternative, for which negative associations are triggered not by every token of a pejorative, but rather by certain of its articulations.
Exempting Least Developed Countries from Border Carbon Adjustments: Simple Economically but Complex Legally
Authors: Sasmal Sunayana , Zhang Dongzhe , Lydgate Emily , Winters L. Alan 
Published: May 2024

AbstractThe EU has introduced a Carbon Border Adjustment Mechanism (CBAM), which extends its carbon prices to imported products in some sectors. Increasingly considered by other countries, such border carbon adjustments (BCAs) are facing a global backlash against the lack of consideration of the adverse impacts on developing countries and particularly, least developed countries (LDCs). This article first argues that small overall import volumes support the conclusion that exempting or lessening BCA requirements from LDCs would not undermine developed countries' climate-related objectives in practical terms. An economic analysis of EU and UK trade in relation to a CBAM supports this assertion. However, legally, such an exemption or development-based preferential treatment is difficult under existing multilateral trade rules and jurisprudence, owing to the legal characterization and objectives of BCAs; their interaction with existing special and differential treatment (SDT) provisions; and complexity of available policy options. We thus highlight the gap between normative aims of SDT provisions to support development, and current WTO law and jurisprudence which expose WTO members providing preferential treatment to allegations of discrimination. With increasing unilateral climate action, an inability to integrate SDT more meaningfully into WTO non-discrimination frameworks risks further weakening of international cooperation on climate and trade.
