Deaf signers are typically multilingual, often exposed to a signed language and a spoken and/or written language. One outcome of this type of contact is ‘mouthing’—the silent articulation of spoken/written words with the simultaneous production of a sign. This article focuses on mouthing patterns in the Kufr Qassem deaf community, in which there is contact between Kufr Qassem Sign Language (KQSL), Israeli Sign Language (ISL), as well as Hebrew, and Arabic, which exists as a diglossia. The findings show that mouthing is constrained by the interlocutor and sign language used, with more mouthing with an ISL interlocutor than KQSL interlocutor, and when using ISL signs than KQSL signs. Contact with a diglossic spoken language shows that signers mouth in Palestinian Arabic rather than in Modern Standard Arabic. Furthermore, evidence of diachronic changes in mouthing was found, reflecting changes in education and mobility.

Functional linear regression has gained popularity as a statistical tool for studying the relationship between function-valued variables. However, in practice, it is hard to expect that the explanatory variables of interest are strictly exogenous, due to, for example, the presence of omitted variables and measurement error. This issue of endogeneity remains insufficiently explored, in spite of its empirical importance. To fill this gap, this article proposes new consistent FPCA-based instrumental variable estimators and develops their asymptotic properties in detail. Simulation experiments under a wide range of settings show that the proposed estimators perform considerably well. We apply our methodology to estimate the impact of immigration on native labor market outcomes in the US.

Previous studies in rodents suggest that mismatch between fetal and postnatal nutrition predisposes individuals to metabolic diseases. We hypothesized that in nonhuman primates (NHP), fetal programming of maternal undernutrition (MUN) persists postnatally with a dietary mismatch altering metabolic molecular systems that precede standard clinical measures. We used unbiased molecular approaches to examine response to a high fat, high-carbohydrate diet plus sugar drink (HFCS) challenge in NHP juvenile offspring of MUN pregnancies compared with controls (CON). Pregnant baboons were fed ad libitum (CON) or 30% calorie reduction from 0.16 gestation through lactation; weaned offspring were fed chow ad libitum. MUN offspring were growth restricted at birth. Liver, omental fat, and skeletal muscle gene expression, and liver glycogen, muscle mitochondria, and fat cell size were quantified. Before challenge, MUN offspring had lower body mass index (BMI) and liver glycogen, and consumed more sugar drink than CON. After HFCS challenge, MUN and CON BMIs were similar. Molecular analyses showed HFCS response differences between CON and MUN for muscle and liver, including hepatic splicing and unfolded protein response. Altered liver signaling pathways and glycogen content between MUN and CON at baseline indicate in utero programming persists in MUN juveniles. MUN catchup growth during consumption of HFCS suggests increased risk of obesity, diabetes, and cardiovascular disease. Greater sugar drink consumption in MUN demonstrates altered appetitive drive due to programming. Differences in blood leptin, liver glycogen, and tissue-specific molecular response to HFCS suggest MUN significantly impacts juvenile offspring ability to manage an energy rich diet.

While scholars have long been interested in the formation, meaning, and uses of diminutive morphology across languages, the present study illustrates a novel approach to their examination. Drawing upon a corpus of recordings of Brazilian obstetric and gynecological consultations conducted in Portuguese, our analytic points of departure are action and the sequential progression of interaction. We address these by investigating moments where diminutive forms and base forms of a lexical item are used in close proximity. This approach allows us to unpack and particularize the generic, overarching function of ‘mitigation’ in terms of the specific actions being constituted by the participants—here, offering reassurance, attenuating intrusiveness, pursuing acquiescence, and launching activity transitions. We conclude by discussing some of the implications of this analysis and suggesting some potential avenues for future comparative research.

From less than three dozen in 1949, the number of small hydropower stations in the People’s Republic of China grew to nearly ninety thousand by 1979. By the early 1980s, these stations were distributed across nearly 1,600 of China’s 2,300 counties. In 770 counties, small hydropower was the primary source of rural electricity generation. This article offers a history and assessment of these developments, unsettling our traditional emphasis on large-scale hydroelectricity. The article begins by reconstructing the PRC’s enormous investments in small hydropower from the 1950s to the early 1980s. This reconstruction, the first of its kind in the English language, not only helps reassess key periods and events in the history of the PRC but also establishes the position of small hydropower in the hydraulic history of the twentieth century. The article then turns to a discussion of the claimed impacts of small hydropower. As electricity became available for the first time in many parts of the Chinese countryside, it affected patterns of economic and social activity for hundreds of millions of people. Finally, the paper explores what the case of small hydropower can offer to conceptual and theoretical problems surrounding development, innovation, and the environment. Returning to the long-standing debate over scale and development, China’s experience with small hydropower reminds us of the important role played by smaller-scale, appropriate, and self-reliant technologies in global energy history.

Continuum robots offer unique advantages in performing tasks within extremely confined environments due to their exceptional dexterity and adaptability. However, their soft materials and elastic structures inherently introduce nonlinearity and shape instability, especially when the robot encounters external contact forces. To address these challenges, this paper presents a comprehensive model and experimental study to estimate the shape deformation of a switchable rigid-continuum robot (SRC-Bot). The kinematic analysis is first conducted to specify the degrees of freedom (DoF) and basic motions of SRC-Bot, including motion of bending, rotating, and elongating. This analysis assumes that the curvature varies along the central axis and maps the relationship between joint space and driven space. Subsequently, an equivalence concept is proposed to unify the stiffness addressing each DoF, which is then utilized in the establishment of the dynamic model. According to the mechanical structural design, the deformed posture of SRC-Bot is discretized into five segments, corresponding to the distribution of the guiders. The dynamics model is then derived using Newton’s second law and Euler’s method to simulate the deformation under gravity, friction, and external forces. Additionally, the stiffness in three directions is quantified through an identification process to complete the theoretical model. Furthermore, a series of experiments are conducted and compared with simulated results to validate the response and deformed behavior of SRC-Bot. The comparative results demonstrate that the proposed model-based simulation accurately captures the deformable characteristics of the robot, encompassing both static deformed postures and dynamic time-domain responses induced by external and actuation forces.

Narratives of the making of the international have a specific configuration of past–present–future that constitutes the unitary character of historical time and continues to reproduce spatio-temporal hierarchies. The article argues that the historical turn in IR has addressed spatio-temporal hierarchies through different timing strategies but has not sufficiently problematised the concept of History specifically with respect to unitary historical time. The article focuses on the problem of a unitary historical time; building on works that have underlined how the past, the present, and the future are not fixed entities given to us by an objective ‘truth’ but rather performatively constructed through different politics of time, it aims to develop an analytical vocabulary to further explore how to write history in the plural. How to write history in the plural will be explored through three different readings of the Haitian Revolution, underlining ‘timeliness/untimeliness’, dialogues between presents and pasts and futures, and past and multiple presents aiming to expand our analytical vocabulary in discussing the historical time of the international.

The role of social movements and civil society actors in rights advancement has been frequently emphasised. The assumption is that legal mobilisation by civil society actors works towards the extension of rights and the emancipation and advancement of justice for distinctive (minority) groups in society. While traditionally, socio-legal attention on social movement and civil society actions around rights promotion was particularly prominent in the US, for some time now the European context has also been approached from such a socio-legal lens. However, a one-sided, liberal–progressive understanding of social mobilisation around rights has, importantly, been put to the test by recent manifestations of societal actors. Conservative actors tend to (1) promote a restrictive interpretation or a radical reinterpretation of existing rights (e.g. abortion, free speech), (2) limit the diffusion of new rights (e.g. the rights to euthanasia or legalizing surrogate maternity) and/or (3) call for the interruption of the further extensions of rights (e.g. with regard to same-sex marriage, LGBTIQ issues). The analysis of legal mobilisation by such conservative right-wing actors indicates that mobilisational repertoires are strikingly similar to those of liberal actors. This article will discuss the notions of civil society and legal mobilisation and call for a rethinking of these concepts, in part because of the increasing manifestation of societal actors that are in contrast to the traditional liberal paradigm. The article will subsequently engage in a detailed study of one such actor – the Polish legal think tank Ordo Iuris (OI) – with regard to its third-party or amicus curiae interventions at the European Court of Human Rights (ECtHR), stressing the difference of orientation of such interventions from those of liberal actors and also indicating dimensions of ambivalence and similarity in their approaches.

Mystical experiences are often regarded as potential sources of epistemic justification for religious beliefs. However, the ‘disanalogy objection’ maintains that, in contrast to sense perceptions, mystical experiences lack social verifiability and are thus merely subjective states that cannot substantiate objective truths. This article explores a novel externalist response that involves the concept of angels. As spiritual beings, angels can directly perceive God and verify these perceptions in their celestial community. Thus, the ‘direct perception of God’ is not inherently incapable of social verification. While invoking angels might appear contentious, it coheres with the externalist approach of conceptualising cognitive states under hypothetical settings. Despite the differences between humans and angels and their lack of interaction for verification purposes, our approach remains valid because mystics not only exemplify the same general type of ‘direct perception of God’ as angels but can also be preliminary members of a wider celestial community.

Given an integer $k\ge 2$, let $\omega _k(n)$ denote the number of primes that divide n with multiplicity exactly k. We compute the density $e_{k,m}$ of those integers n for which $\omega _k(n)=m$ for every integer $m\ge 0$. We also show that the generating function $\sum _{m=0}^\infty e_{k,m}z^m$ is an entire function that can be written in the form $\prod _{p} \bigl (1+{(p-1)(z-1)}/{p^{k+1}} \bigr )$; from this representation we show how to both numerically calculate the $e_{k,m}$ to high precision and provide an asymptotic upper bound for the $e_{k,m}$. We further show how to generalize these results to all additive functions of the form $\sum _{j=2}^\infty a_j \omega _j(n)$; when $a_j=j-1$ this recovers a classical result of Rényi on the distribution of $\Omega (n)-\omega (n)$.

This study focuses on the kinematic and dynamic modeling of a wheeled-legged robot (WLR), taking into account kinematic and dynamic slippage. In this regard, the Gibbs–Appell formulation was utilized to derive dynamic equations. Determining the slippage in the wheels for movement equations is a challenging task due to its dependency on factors such as the robot’s postures, velocities, and surface characteristics. To address this challenge, machine vision was used to quantify the slippage of the wheels on the body based on the pose estimation method. This data served as input for movement equations to analyze the robot’s deviation from its path and posture. In the following, the robot’s movement was simulated using Webots and MATLAB, followed by various experimental tests involving acceleration and changes in leg angles on the WLR. The results were then compared to the simulations to demonstrate the accuracy of the developed system modeling. Additionally, an IMU sensor was utilized to measure the robot’s motion and validate against machine vision data. The findings revealed that neglecting the slippage of the wheels in the robot’s motion modeling resulted in errors ranging from 5% to 11.5%. Furthermore, lateral slippage ranging from 1.1 to 5.2 cm was observed in the robot’s accelerated movement. This highlights the importance of including lateral slippage in the equations for a more precise modeling of the robot’s behavior.

We have previously demonstrated that calcium plus vitamin D supplementation during adolescent pregnancy reduces the magnitude of transient postpartum bone mass loss. In the present post hoc analysis, we further investigated the effect of calcium plus vitamin D supplementation during pregnancy in hip geometry throughout one year postpartum in Brazilian adolescents with low daily calcium intake (∼600 mg/d). Pregnant adolescents (14–19 years) were randomly assigned to receive calcium (600 mg/d) plus vitamin D3 (200 μg/d) or a placebo from 26 weeks of gestation until parturition. Dual-energy X-ray absorptiometry images were obtained at 5 (n 30 and 26 for calcium plus vitamin D and placebo, respectively), 20 (n 26 and 21) and 56 (n 18 and 12) weeks postpartum, and hip geometry parameters were analysed by Advanced Hip Assessment software. The effects of the intervention, time point and their interaction were assessed using repeated-measures mixed-effects models. No significant intervention effects or intervention × time interactions were observed on hip geometry parameters (P > 0·05). Time effects were observed in cross-sectional area, cross-sectional moment of inertia and section modulus parameters with decreases from the 5th to the 20th week postpartum followed by recovery from the 20th to the 56th week (P < 0·05). Our findings indicate that the postpartum period is associated with transient changes in the hip geometry of lactating adolescent mothers, regardless of the low calcium intake and the supplementation offered during pregnancy, suggesting that a physiological adaptation of these adolescents to low calcium intake is at play.

In the past five years, there has been a striking increase in the number of people experiencing homelessness, including unsheltered homelessness, across Canada (Infrastructure Canada, 2024). Facing this growing crisis, local governments are changing and expanding their responses. An important innovation is tiny homes, a form of deeply affordable and supportive housing for people leaving homelessness. In this brief article, I ask what explains local government's increased leadership and innovation with respect to homelessness and housing crises. Drawing on interviews and document analysis regarding the development of a tiny homes community in a mid-sized BC municipality, I identify three factors that have contributed to local government's policy innovation: 1) local officials are keenly aware of the inadequacies of federal and provincial responses and of the need for alternative approaches; 2) they hold important resources, notably local knowledge and land; and 3) they are facing pressure to respond from citizens and service providers.

This paper analyses the growing litigation before the European Court of Human Rights (ECtHR) by conservative European Non-governmental Organizations (NGOs) who exploit legal opportunities and other advocacy tactics. These actors oppose the liberal insistence on permissive individual freedom, minority rights and mandatory vaccination. Instead, they promote the sanctity of life, traditional values and harsh terrorism penalties. In this study we show that conservative legal mobilisation is not only related to litigation but also covers the execution of certain ECtHR judgments and the nomination of some European judges. We analyse their tactics using legal and sociolegal methodology (interviews, analysis of legal documents and jurisprudence and network analysis) to characterise their influence on the European human rights system and the reactions of the Council of Europe. We reflect on the moral values claimed by conservative NGOs and their liberal counterparts by analysing how powerful private actors, driven by material and moral interests, take creative initiatives that shape or reshape case law and its politicisation through alliances with so-called ‘illiberal’ and ‘populist’ states.

This article serves as an introduction to the special issue on ‘Populism and Right-Wing Legal Mobilization in Europe’. We point to the dependence of populists in power on non-state actors: populist governments have ideological and political reasons to need the support of civil society’s right-wing representatives and have the financial and institutional means to strengthen those organizations. We then map right-wing legal mobilization in Europe based on the analyses in the special issue. By right-wing legal mobilization, we understand the organized efforts, resources, and strategies employed by individuals, groups, or organizations with conservative or right-leaning ideologies to embody their values in positive law and its interpretation. The text concludes with a dynamic normative framework to assess this type of mobilization. Drawing on recent contributions from comparative constitutional law, human rights, and socio-legal studies, we argue that the analysis and evaluation of right-wing legal mobilization could be based on a comprehensive analysis of three bundles of issues: (1) the relationship between mobilizing actors and the courts, as well as the local standard of judicial independence, (2) the relation of right-wing argumentation to systemic linkages and historical trajectories of human rights, (3) the redistributive effect (economic and symbolic) and the potential success of such mobilization on the legal capacities of other actors who may have opposing interests. From this perspective, the problematic part of right-wing legal mobilization in the context of populism is, therefore, not its ideological, conservative character but its influence on the rule of law to gain strategic advantage. In the process, the very idea of the rule of law and the related issue of civic agency may be compromised.

Though the Polish rule of law crisis has been on the scholarly agenda since the Law and Justice Party (PiS) took power in 2015, the individual agents of legal disruption within the judiciary have been largely off the radar. This intervention aims to fill this gap. This article analyses the legal mobilisation practices of the Supreme Court (SC) judges appointed by the PiS party in a court-packing manner after 2017. It is argued that this is a specific type of legal mobilisation; because it is conducted from within the legal system by judges, it aims to challenge doctrinal views strategically and to legitimise the status of unlawfully elected judges, which consequently destabilises the legal system. Because the legal tools to solve the conflict appear to have been exhausted, new judges engage in public discourse to convince citizens that they have a right to sit on the bench. In the first part of this paper, I critically analyse this public discourse in order to explain the framing of the rule of law crisis. The analysis of this discourse is drawn from 106 texts produced by new SC judges between 2017 and 2023. It is argued that although the ‘populist’ group of SC judges is internally differentiated and does not exhibit clear ideological linkage with the PiS party, it strategically produces certain legal narratives in which their appointments and judicial practices at the SC conform to the Constitution and to relevant statutes and, as such, are legitimate in legal terms. The new judges’ narratives are based on four populist dichotomies that distinguish them from old judges (legitimacy–lack of legitimacy, autonomy–political dependence, formal rule of law–legal anarchy and accountability–corporatism). In the second part, the article proceeds to analyse selected case law of the Supreme Court to explore whether and how court-packing makes it more responsive to the legal mobilisation of the conservative Christian organisation Ordo Iuris (OI) and helps the governing party maintain its power. It is argued that the judicial mobilisation inside the packed Supreme Court is mostly of a discursive nature, as there is limited evidence that newly appointed judges side ideologically with the government and right-wing organisations in recent case law.
