A multi-modal context-aware sequence stage validation for human-centric AR assembly

Augmented reality (AR) has demonstrated its superior performance to benefit manual assembly tasks by delivering intuitive guidance on the workbench directly, alleviating the mental load while leading to time-saving operations. Nevertheless, current AR-assisted assembly mainly focuses on superimposing visual instructions onto real scenarios and assumes that the worker performs correctly as instructed, ignoring the confirmation of the actual assembly execution processes, and it is still difficult to avoid operating errors on the shop floor. To this end, this paper aims to propose a multi-modal context-aware on-site assembly stage recognition for human-centric AR assembly. Firstly, a sim-real point cloud-based semantic understanding method for assembly stage identification is presented, which can recognize the current sequence stage during the AR assembly process even when encountering weakly textured workpieces. In addition, a 2D image-based semantic recognition for on-site images is applied as compensation from the RGBD camera, resulting in a robust multi-modal context-aware assembly stage validation for the ongoing AR assembly tasks. Followed by a context-aware closed-loop AR assembly system that provides actual assembly result confirmation automatically, relieving the mental load for workers to activate the next assembly instruction, as well as confirm the current status during the actual operation. Finally, extensive experiments are carried out, and the results illustrate that the proposed context-aware AR assembly system can monitor the on-site sequence stage while providing a human-centric AR assembly action.

Inhibitory Pedunculopontine Neurons Gate Dopamine-Mediated Motor Actions of Unsigned Valence.

The pedunculopontine nucleus (PPN) maintains a bidirectional connectivity with the basal ganglia that supports their shared roles in the selection and execution of motor actions. Previous studies identified a role for PPN neurons in goal-directed behavior, but the cellular substrates underlying this function have not been elucidated. We recently revealed the existence of a monosynaptic GABAergic input from the PPN that inhibits dopamine neurons of the substantia nigra. Activation of this pathway interferes with the execution of learned motor sequences when the actions are rewarded, even though the inhibition of dopamine neurons did not shift the value of the action, hence suggesting executive control over the gating of behavior. To test the attributes of the inhibition of dopamine neurons by the PPN in the context of goal-directed behavior regardless of whether the outcome is positively or negatively reinforced. We delivered optogenetic stimulation to PPN GABAergic axon terminals in the substantia nigra during a battery of behavioral tasks with positive and negative valence. Inhibition of dopamine neurons by PPN optogenetic activation during an appetitive task impaired the initiation and overall execution of the behavioral sequence without affecting the consumption of reward. During an active avoidance task, the same activation impaired the ability of mice to avoid a foot shock, but their escape response was unaffected. In addition, responses to potential threats were significantly attenuated. Our results show that PPN GABAergic neurons modulate learned, goal-directed behavior of unsigned valence without affecting overall motor behavior.

Sensory Reinforced Corticostriatal Plasticity.

Regional changes in corticostriatal transmission induced by phasic dopaminergic signals are an essential feature of the neural network responsible for instrumental reinforcement during discovery of an action. However, the timing of signals that are thought to contribute to the induction of corticostriatal plasticity is difficult to reconcile within the framework of behavioural reinforcement learning, because the reinforcer is normally delayed relative to the selection and execution of causally-related actions. While recent studies have started to address the relevance of delayed reinforcement signals and their impact on corticostriatal processing, our objective was to establish a model in which a sensory reinforcer triggers appropriately delayed reinforcement signals relayed to the striatum via intact neuronal pathways and to investigate the effects on corticostriatal plasticity. We measured corticostriatal plasticity with electrophysiological recordings using a light flash as a natural sensory reinforcer, and pharmacological manipulations were applied in an in vivo anesthetized rat model preparation. We demonstrate that the spiking of striatal neurons evoked by single-pulse stimulation of the motor cortex can be potentiated by a natural sensory reinforcer, operating through intact afferent pathways, with signal timing approximating that required for behavioural reinforcement. The pharmacological blockade of dopamine receptors attenuated the observed potentiation of corticostriatal neurotransmission. This novel in vivo model of corticostriatal plasticity offers a behaviourally relevant framework to address the physiological, anatomical, cellular, and molecular bases of instrumental reinforcement learning.

Regulator of G Protein Signaling 14 protein expression profile in the adult mouse brain.

Regulator of G protein signaling 14 (RGS14) is a multifunctional signaling protein that serves as a natural suppressor of synaptic plasticity in the mouse brain. Our previous studies showed that RGS14 is highly expressed in postsynaptic dendrites and spines of pyramidal neurons in hippocampal area CA2 of the developing mouse brain. However, our more recent work with adult rhesus macaque brain shows that RGS14 is found in multiple neuron populations throughout hippocampal area CA1 and CA2, caudate nucleus, putamen, globus pallidus, substantia nigra, and amygdala in the adult rhesus monkey brain. In the mouse brain, we also have observed RGS14 protein in discrete limbic regions linked to reward behavior and addiction, including the central amygdala and the nucleus accumbens, but a comprehensive mapping of RGS14 protein expression in the adult mouse brain is lacking. Here, we report that RGS14 is more broadly expressed in mouse brain than previously known. Intense RGS14 staining is observed in specific neuron populations of the hippocampal formation, amygdala, septum, bed nucleus of stria terminalis and ventral striatum/nucleus accumbens. RGS14 is also observed in axon fiber tracts including the dorsal fornix, fimbria, stria terminalis, and the ventrohippocampal commissure. Moderate RGS14 staining is observed in various other adjacent regions not previously reported. These findings show that RGS14 is expressed in brain regions that govern aspects of core cognitive functions such as sensory perception, emotion, memory, motivation, and execution of actions, and suggests that RGS14 may serve to suppress plasticity and filter inputs in these brain regions to set the overall tone on experience-to-action processes.

Documenting and analyzing pre-reflective self-consciousness underlying ongoing performance optimization in elite athletes: the theoretical and methodological approach of the course-of-experience framework.

Traditional theories of motor learning emphasize the automaticity of skillful actions. However, recent research has emphasized the role of pre-reflective self-consciousness accompanying skillful action execution. In the present paper, we present the course-of-experience framework as a means of studying elite athletes' pre-reflective self-consciousness in the unfolding activity of performance optimization. We carried out a synthetic presentation of the ontological and epistemological foundation of this framework. Then we illustrated the methodology by an in-depth analysis of two elite windsurfers' courses of experience. The analysis of global and local characteristics of the riders' courses of experience reveal (a) the meaningful activities accompanying the experience of ongoing performance optimization; (b) the multidimensionality of attentional foci and the normativity of performance self-assessment; and (c) a micro-scale phenomenological description of continuous improvement. These results highlight the fruitfulness of the course-of-experience framework to describe the experience of being absorbed in an activity of performance optimization.

Effects of psilocybin on uncertain punishment learning

Psilocybin may provide a useful treatment for mood disorders including anxiety and depression but its mechanisms of action for these effects are not well understood. While recent preclinical work has begun to assess psilocybin’s role in affective behaviors through innate anxiety or fear conditioning, there is scant evidence for its role in conflict between reward and punishment. The current study was designed to determine the impact of psilocybin on the learning of reward-punishment conflict associations, as well as its effects after learning, in male and female rats. We utilized a chained schedule of reinforcement that involved execution of safe and risky reward-guided actions under uncertain punishment. Different patterns of behavioral suppression by psilocybin emerged during learning versus after learning of risky action-reward associations. Psilocybin increased behavioral suppression in female rats as punishment associations were learned. After learning, psilocybin decreased behavioral suppression in both sexes. Thus, psilocybin produces divergent effects on action suppression during approach-avoidance conflict depending on when the conflict is experienced. This observation may have implications for its therapeutic mechanism of action.

Contextual expectations shape the motor coding of movement kinematics during the prediction of observed actions: A TMS study

Contextual information may shape motor resonance and support intention understanding during observation of incomplete, ambiguous actions. It is unclear, however, whether this effect is contingent upon kinematics ambiguity or contextual information is continuously integrated with kinematics to predict the overarching action intention. Moreover, a differentiation between the motor mapping of the intention suggested by context or kinematics has not been clearly demonstrated. In a first action execution phase, 29 participants were asked to perform reaching-to-grasp movements towards big or small food objects with the intention to eat or to move; electromyography from the First Dorsal Interosseous (FDI) and Abductor Digiti Minimi (ADM) was recorded. Depending on object size, the intentions to eat or to move were differently implemented by a whole-hand or a precision grip kinematics, thus qualifying an action-muscle dissociation. Then, in a following action prediction task, the same participants were asked to observe an actor performing the same actions and to predict his/her intention while motor resonance was assessed for the same muscles. Of note, videos were interrupted at early or late action phases, and actions were embedded in contexts pointing toward an eating or a moving intention, congruently or incongruently with kinematics. We found greater involvement of the FDI or ADM in the execution of precision or whole-hand grips, respectively. Crucially, this pattern of activation was mirrored during observation of the same actions in congruent contexts, but it was cancelled out or reversed in the incongruent ones, either when videos were interrupted at either early or long phases of action deployment. Our results extend previous evidence by showing that contextual information shapes motor resonance not only under conditions of perceptual uncertainty but also when more informative kinematics is available.

Online chasing action recruits both mirror neuron and mentalizing systems: A pilot fNIRS study

Engaging in chasing, where an actor actively pursues a target, is considered a crucial activity for the development of social skills. Previous studies have focused predominantly on understanding the neural correlates of chasing from an observer's perspective, but the neural mechanisms underlying the real-time implementation of chasing action remain poorly understood. To gain deeper insights into this phenomenon, the current study employed functional near-infrared spectroscopy (fNIRS) techniques and a novel interactive game. In this interactive game, participants (N = 29) were tasked to engage in chasing behavior by controlling an on-screen character using a gamepad, with the goal of catching a virtual partner. To specifically examine the brain activations associated with the interactive nature of chasing, we included two additional interactive actions: following action of following the path of a virtual partner and free action of moving without a specific pursuit goal. The results revealed that chasing and following actions elicited activation in a broad and overlapping network of brain regions, including the temporoparietal junction (TPJ), medial prefrontal cortex (mPFC), premotor cortex (PMC), primary somatosensory cortex (SI), and primary motor cortex (M1). Crucially, these regions were found to be modulated by the type of interaction, with greater activation and functional connectivity during the chasing interaction than during the following and free interactions. These findings suggested that both the MNS, encompassing regions such as the PMC, M1 and SI, and the mentalizing system (MS), involving the TPJ and mPFC, contribute to the execution of online chasing actions. Thus, the present study represents an initial step toward future investigations into the roles of MNS and MS in real-time chasing interactions.

Two distinct networks for encoding goals and forms of action: An effective connectivity study

Goal-directed actions are characterized by two main features: the content (i.e., the action goal) and the form, called vitality forms (VF) (i.e., how actions are executed). It is well established that both the action content and the capacity to understand the content of another's action are mediated by a network formed by a set of parietal and frontal brain areas. In contrast, the neural bases of action forms (e.g., gentle or rude actions) have not been characterized. However, there are now studies showing that the observation and execution of actions endowed with VF activate, in addition to the parieto-frontal network, the dorso-central insula (DCI). In the present study, we established-using dynamic causal modeling (DCM)-the direction of information flow during observation and execution of actions endowed with gentle and rude VF in the human brain. Based on previous fMRI studies, the selected nodes for the DCM comprised the posterior superior temporal sulcus (pSTS), the inferior parietal lobule (IPL), the premotor cortex (PM), and the DCI. Bayesian model comparison showed that, during action observation, two streams arose from pSTS: one toward IPL, concerning the action goal, and one toward DCI, concerning the action vitality forms. During action execution, two streams arose from PM: one toward IPL, concerning the action goal and one toward DCI concerning action vitality forms. This last finding opens an interesting question concerning the possibility to elicit VF in two distinct ways: cognitively (from PM to DCI) and affectively (from DCI to PM).

Improving Speaking Skills of 11th Graders at Nguyen Trai High School Using Role Play: Students’ Perspectives

This study investigates the efficacy of role-play as an instructional strategy for improving speaking skills and investigates students’ attitudes towards this technique. Conducted at Nguyen Trai High School, the research adopted an action research approach, encompassing planning, execution, observation, and reflection within a single cycle. A cohort of 40 eleventh-grade students during the 2022/2023 academic year participated. The study employed direct observation to gauge student attitudes towards role-play and its impact on speaking abilities. Additionally, a questionnaire survey was administered to collect student opinions on the role-play method and speaking skills. Further insights were gleaned through interviews with select students, aimed at delving deeper into their questionnaire responses and validating the accuracy of feedback. This mixed-methods approach facilitated an assessment of role-play’s effectiveness in enhancing speaking skills, with findings suggesting a significant improvement in students’ speaking competence.

대학생을 위한 단회기 진로상담 모형 및 운영 매뉴얼 개발

Objectives The purpose of this study is to develop a career counseling model and manual so that career counseling instructors (or school counselors) can provide career counseling services to students (clients) during one session (single session). Methods For this purpose, we conducted a literature analysis and collected basic data by analyzing the current status of career counseling linked to career courses at D University in Gyeonggi-do. Based on basic data, the theoretical components of the research model were selected and the opinions of the expert group were collected to establish the research model. In the second Delphi survey, the suitability of the research model was verified and expert opinions were collected on the components of the career counseling manual. In the third Delphi survey, the validity of the single-session career counseling manual was verified. Results The single-session career counseling model consisted of a total of four stages. Step 1 is the start/preparation step, step 2 is the in-depth exploration step, step 3 is the action execution step, and step 4 is the finishing step. The career counseling manual consists of a total of 6 chapters. Chapter 1 outlines single-session career counseling (definition of single-session career counseling, operating period, operation procedure), chapter 2 prepares for single-session career counseling (application and operation method for counseling, how to use Online, schedule management method, notes, Guidance on screening potential students and related support), Chapter 3, single-session career counseling process and strategies (4 stages of single-session career counseling, career counseling intervention strategies), Chapter 4, counseling guide by type of career problem (types of career counseling for college students and intervention strategies, majors) Cases according to satisfaction and goal setting), Chapter 5 Examination of counselor preparation behavior (consultation preparation checklist, basic role of counselor, communication checklist, core skills of counseling), Chapter 6 Appendix (Risk assessment of high-risk group, satisfaction with major, career goals), conflict situation, goal setting, list for career efficacy, etc.). Conclusions A model was developed so that career course instructors (counselors) could efficiently counsel many students (clients) within a limited time, and a manual was developed to facilitate smooth counseling activities. Although single-session counseling has existed for a long time, it is meaningful that a plan that can be practically used in a situation where there are not many studies has been prepared.

The plasticity of pyramidal neurons in the behaving brain.

Neurons are plastic. That is, they change their activity according to different behavioural conditions. This endows pyramidal neurons with an incredible computational power for the integration and processing of synaptic inputs. Plasticity can be investigated at different levels of investigation within a single neuron, from spines to dendrites, to synaptic input. Although most of our knowledge stems from the in vitro brain slice preparation, plasticity plays a vital role during behaviour by providing a flexible substrate for the execution of appropriate actions in our ever-changing environment. Owing to advances in recording techniques, the plasticity of neurons and the neural networks in which they are embedded is now beginning to be realized in the in vivo intact brain. This review focuses on the structural and functional synaptic plasticity of pyramidal neurons, with a specific focus on the latest developments from in vivo studies. This article is part of a discussion meeting issue 'Long-term potentiation: 50 years on'.

A domain-independent agent architecture for adaptive operation in evolving open worlds

1Angry Birds Competition. Model-based reasoning agents are ill-equipped to act in novel situations in which their model of the environment no longer sufficiently represents the world. We propose HYDRA, a framework for designing model-based agents operating in mixed discrete-continuous worlds that can autonomously detect when the environment has evolved from its canonical setup, understand how it has evolved, and adapt the agents' models to perform effectively. HYDRA is based upon PDDL+, a rich modeling language for planning in mixed, discrete-continuous environments. It augments the planning module with visual reasoning, task selection, and action execution modules for closed-loop interaction with complex environments. HYDRA implements a novel meta-reasoning process that enables the agent to monitor its own behavior from a variety of aspects. The process employs a diverse set of computational methods to maintain expectations about the agent's own behavior in an environment. Divergences from those expectations are useful in detecting when the environment has evolved and identifying opportunities to adapt the underlying models. HYDRA builds upon ideas from diagnosis and repair and uses a heuristics-guided search over model changes such that they become competent in novel conditions. The HYDRA framework has been used to implement novelty-aware agents for three diverse domains - CartPole++ (a higher dimension variant of a classic control problem), Science Birds (an IJCAI competition problem1), and PogoStick (a specific problem domain in Minecraft). We report empirical observations from these domains to demonstrate the efficacy of various components in the novelty meta-reasoning process.

PENGARUH PARTISIPASI ANGGARAN, KOMITMEN ORGANISASI, DAN BUDGET EMPHASIS TERHADAP BUDGETARY SLACK PADA HOTEL BINTANG 5 DI BADUNG

The budget is a tool utilized by companies to regulate resource utilization within a specified timeframe. However, discrepancies frequently arise between the planned budget and actual execution, potentially leading to what is known as budgetary slack. This slack occurs due to conflicts between those setting the budget and those implementing it. Among the factors contributing to budgetary slack are involvement in budgeting, dedication to the organization, and emphasis placed on the budget. This study aims to explore how involvement in budgeting, dedication to the organization, and emphasis on the budget impact budgetary slack within the setting of 5-star hotels in Badung. It adopts a quantitative approach, with the population consisting of 65 5-star hotels in Badung. The sample comprises 220 respondents selected through non-probability sampling, specifically use ipurposive isampling. Multiple linear regressiont ianalysis is utilized for data ianalysis. The findings reveal that both involvement in budgeting and emphasis on the budget positively affect ibudgetary slack in 5-star hotels in Badung. Conversely, dedication to the organization demonstrates a negative correlation with budgetary slack in the same context. The combined influence of involvement in budgeting, dedication to organization, and emphasis on the budget accounts for 44.5% of the variability in budgetary slack, while the remaining 55.5% is attributed to external variable not addressed in this study.

Europeanisation in the aftermath of COVID-19: the organisational adaptation of the central governance of the National Recovery and Resilience Plan in Italy

AbstractWhile much of the recent literature on the impact of COVID-19 has focussed on governance at the EU level and specific policy areas, the changing political institutional arrangements within the EU Member States themselves have received significantly less attention. This article aims to contribute filling this gap by asking: how, and to what extent, has the core executive in Italy changed to manage and implement the National Recovery and Resilience Plan (NRRP)? Italy has been heavily hit by the COVID-19 pandemic and has subsequently been allocated the largest proportion of the Next Generation EU (NGEU) funds: it is therefore a ‘most likely’ case of organisational adaptation. We argue that the implementation of the NRRP triggers centralisation of power in the core executive. Such concentration of power, however, takes different forms depending on the composition of the executive. We also find that ‘coordinative’ Europeanisation occurs through the continuous interaction and exchange between the executive actors (political and administrative) based in Rome and the European Commission in Brussels. Such interaction showcases the attempt to manage both further integration and politicisation of the EU. The collaboration between the European Commission and the national executive is based both on the recognition of the value of the political ownership of the NRRP and the importance of the EU support for post-pandemic recovery.

Applications of Brain Wave Classification for Controlling an Intelligent Wheelchair

The independence and autonomy of both elderly and disabled people have been a growing concern in today’s society. Therefore, wheelchairs have proven to be fundamental for the movement of these people with physical disabilities in the lower limbs, paralysis, or other type of restrictive diseases. Various adapted sensors can be employed in order to facilitate the wheelchair’s driving experience. This work develops the proof concept of a brain–computer interface (BCI), whose ultimate final goal will be to control an intelligent wheelchair. An event-related (de)synchronization neuro-mechanism will be used, since it corresponds to a synchronization, or desynchronization, in the mu and beta brain rhythms, during the execution, preparation, or imagination of motor actions. Two datasets were used for algorithm development: one from the IV competition of BCIs (A), acquired through twenty-two Ag/AgCl electrodes and encompassing motor imagery of the right and left hands, and feet; and the other (B) was obtained in the laboratory using an Emotiv EPOC headset, also with the same motor imaginary. Regarding feature extraction, several approaches were tested: namely, two versions of the signal’s power spectral density, followed by a filter bank version; the use of respective frequency coefficients; and, finally, two versions of the known method filter bank common spatial pattern (FBCSP). Concerning the results from the second version of FBCSP, dataset A presented an F1-score of 0.797 and a rather low false positive rate of 0.150. Moreover, the correspondent average kappa score reached the value of 0.693, which is in the same order of magnitude as 0.57, obtained by the competition. Regarding dataset B, the average value of the F1-score was 0.651, followed by a kappa score of 0.447, and a false positive rate of 0.471. However, it should be noted that some subjects from this dataset presented F1-scores of 0.747 and 0.911, suggesting that the movement imagery (MI) aptness of different users may influence their performance. In conclusion, it is possible to obtain promising results, using an architecture for a real-time application.

Task-in-Process in Breakout Rooms eines aufgabenbasierten Videokonferenzprojekts

This paper explores the transformative impact of digitalization on foreign language education, particularly in the context of Emergency Remote Teaching (ERT) during the COVID-19 pandemic. Focusing on the use of the programmes like Teams with video conferencing capabilities, this study delves into the interactions of student groups in Breakout Rooms (BOR) during language learning tasks. Grounded in the theoretical framework of task-based language teaching (TBLT) and technology-mediated TBLT, the article investigates how four groups of 10th-grade students organise their work processes and implement task-based language learning while completing a creative task. The study addresses a gap in existing research by examining the actual execution of tasks in BOR, offering insights into the dynamics of student collaboration and language use in a technologyenhanced language learning environment.

Extra-nuclear and cytoplasmic steroid receptor signalling in hormone dependent cancers

Steroid hormone receptors are key mediators in the execution of hormone action through a combination of genomic and non-genomic action. Since their isolation and characterisation in the early 20th Century much of our understanding of the biological actions of steroid hormones are underpinned by their activated receptor activity. Over the past two decades there has been an acceleration of more omics-based research which has resulted in a major uptick in our comprehension of genomic steroid action. However, it is well understood that steroid hormones can induce very rapid signalling events in tandem with their genomic actions wherein they exert their influence through alterations in gene expression. Thus the totality of genomic and non-genomic steroid action occurs in a simultaneous and reciprocal manner and a greater appreciation of whole cell action is required to fully evaluate steroid hormone activity in vivo. In this mini-review we outline the most recent developments in non-genomic steroid action and cytoplasmic steroid hormone receptor biology in endocrine-related cancers with a focus on the 3-keto steroid receptors, in particular the androgen receptor.

Inequivalent and uncorrelated response priming in motor imagery and execution.

Theoretical considerations on motor imagery and motor execution have long been dominated by the functional equivalence view. Previous empirical works comparing these two modes of actions, however, have largely relied on subjective judgments on the imagery process, which may be exposed to various biases. The current study aims to re-examine the commonality and distinguishable aspects of motor imagery and execution via a response repetition paradigm. This framework aims to offer an alternative approach devoid of self-reporting, opening the opportunity for less subjective evaluation of the disparities and correlations between motor imagery and motor execution. Participants performed manual speeded-choice on prime-probe pairs in each trial under three conditions distinguished by the modes of response on the prime: mere observation (Perceptual), imagining response (Imagery), and actual responses (Execution). Responses to the following probe were all actual execution of button press. While Experiment 1 compared the basic repetition effects in the three prime conditions, Experiment 2 extended the prime duration to enhance the quality of MI and monitored electromyography (EMG) for excluding prime imagery with muscle activities to enhance specificity of the underlying mechanism. In Experiment 1, there was no significant repetition effect after mere observation. However, significant repetition effects were observed in both imagery and execution conditions, respectively, which were also significantly correlated. In Experiment 2, trials with excessive EMG activities were excluded before further statistical analysis. A consistent repetition effect pattern in both Imagery and Execution but not the Perception condition. Now the correlation between Imagery and Execution conditions were not significant. Findings from the current study provide a novel application of a classical paradigm, aiming to minimize the subjectivity inherent in imagery assessments while examining the relationship between motor imagery and motor execution. By highlighting differences and the absence of correlation in repetition effects, the study challenges the functional equivalence hypothesis of imagery and execution. Motor representations of imagery and execution, when measured without subjective judgments, appear to be more distinguishable than traditionally thought. Future studies may examine the neural underpinnings of the response repetition paradigm to further elucidating the common and separable aspects of these two modes of action.

CompLaw: A Coding Protocol and Database for the Comparative Study of Judicial Review

Abstract A growing theoretical literature identifies how the process of constitutional review shapes judicial decision-making, legislative behavior, and even the constitutionality of legislation and executive actions. However, the empirical interrogation of these theoretical arguments is limited by the absence of a common protocol for coding constitutional review decisions across courts and time. We introduce such a coding protocol and database (CompLaw) of rulings by 42 constitutional courts. To illustrate the value of CompLaw, we examine a heretofore untested empirical implication about how review timing relates to rulings of unconstitutionality (Ward and Gabel 2019). First, we conduct a nuanced analysis of rulings by the French Constitutional Council over a 13-year period. We then examine the relationship between review timing and strike rates with a set of national constitutional courts in one year. Our data analysis highlights the benefits and flexibility of the CompLaw coding protocol for scholars of judicial review.
