The discussion highlights the need to distinguish between perceptions and the experiences implicated by perceptions, noting that Coliva’s framework makes perception irrelevant to justified belief, except for being the contingent means by which we are furnished with experiences that are the real source of justified belief. It then addresses two issues concerning the problem of cognitive locality. The problem concerns what enables us rationally to suppose that our perceptual experiences mostly put us in touch with reality. The issues addressed are: (1) whether, assuming that there is a problem of cognitive locality, Coliva’s Moderate position adequately addresses it; and (2) whether Coliva gives us enough to make sense of the claim, central to the Moderate position, that certain background presuppositions are constitutive of empirical rationality.

Purpose – The aim of the paper is to determine the perception of extended warranty when communicated by retailer during the sales promotion of durable products (e.g. refrigerators). We consider perception as five signals or conceptual dimensions in retail context. The research question is: What perception creates the extended warranty? The dimensions studied can increase or decrease the value and therefore attractiveness of the product. In this sense, extended warranties are a tool that retailers can use to change customers’ attitudes towards a product. There is little primary research that shows how communication of extended warranties influences customer perception and which signals are relevant to customers and retailers. Research methodology – A survey was conducted on a sample of 180 respondents. The measurement model includes extended warranty as a construct with five observed variables related to customer sentiment (risk relief, no cost, quality, price and brand). Each sentiment signal is tested as a separate hypothesis. The model was tested with SEM and CFA was used to interpret the data. Findings – In advertising theory, the extended warranty is seen as a signal of better quality and reliability, but we have shown that it creates a sense of risk relief in the purchase decision. Research limitations – Extended warranties can give rise to perceptions other than those examined in the measurement model. For different categories of consumer goods, the warranty features can be perceived differently. Practical implications – Retailers design promotional activities by communicating extended warranty to customers. As a result, they do not perceive promoted object as a more expensive due to warranty provision, even though it offers value to customers. Originality/Value – The originality of the article lies in the different perceptions that arise when customers are confronted with an extended warranty as part of the product promotion in a store. The empirical model proposes a construct of perception of the extended warranty mediated by a unique combination of signals such as risk relief, no cost sentiment, quality, price, and brand value. Only two signals, namely risk relief and quality, influence purchase intention.

South Korean President Yoon Suk Yeol's statement on nuclear acquisition resonates throughout the United States, raising speculations about his intent. Although the U.S. has made strides to reassure South Korea by establishing the Nuclear Consultative Group in 2023, the South Korean public's heightened threat perception of North Korea has neither been assuaged nor translated into support for the U.S. extended deterrence. This situation contradicts existing literature, which posits that a state's restraint on nuclear armament can be attributed to the security guarantee provided by its nuclear ally. To resolve this puzzle, this study explores the nature of the South Korean public's threat perception and the factors determining its support for the U.S. extended deterrence. Empirical analyses demonstrate that South Korean public's threat perception of North Korea is substantially high in both progressive and conservative blocs. However, South Koreans would rather develop their own nuclear weapon than rely on extended deterrence.

In this article, we propose a conformal model for 3D visual perception. In our model, the two views are fused in an extended 3D horopter model. For visual simultaneous localization and mapping (SLAM), an extended Kalman filter (EKF) technique is used for 3D reconstruction and determination of the robot head pose. In addition, the Viola and Jones machine-learning technique is applied to improve the robot relocalization. The 3D horopter, the EKF-based SLAM, and the Viola and Jones machine-learning technique are key elements for building a strong real-time perception system for robot humanoids. A variety of interesting experiments show the efficiency of our system for humanoid robot vision.

Learning temporal abstractions which are partial solutions to a task and could be reused for other similar or even more complicated tasks is intuitively an ingredient which can help agents to plan, learn and reason efficiently at multiple resolutions of perceptions and time. Just like humans acquire skills and build on top of already existing skills to solve more complicated tasks, AI agents should be able to learn and develop skills continually, hierarchically and incrementally over time. In my research, I aim to answer the following question: How should an agent efficiently represent, learn and use knowledge of the world in continual tasks? My work builds on the options framework, but provides novel extensions driven by this question. We introduce the notion of interest functions. Analogous to temporally extended actions, we propose learning temporally extended perception. The key idea is to learn temporal abstractions unifying both action and perception.

Memetics is a Darwinian approach to evolution of culture proposed in late 1970s. This thesis proposes an approach to Memetics, which is an effort to overcome some of the problems involved. It is argued in this thesis that units of cultural evolution are functional abstraction of physical reality and are realized within the boundaries of our cognitive processes. The boundaries of human cognitive processes are defined by Clark and Chalmers (1998) in their extended cognition hypothesis according to which, human cognition is understood as a part of the cultural environment. Therefore human cognition and cultural environment can best be understood by studying them together. As for identifying these units, an extended functionalist approach has been proposed and an empirical cultural transmission study has been conducted and explored in the thesis.

Cette thèse se concentre sur la conception et l'utilisation d'environnements de Réalité Etendue (RE) comme soutien à la perception sensorielle d'enfants autistes.Alors que la recherche sur l'autisme en RE, allant de la Réalité Augmentée (RA) à la Réalité Virtuelle (RV), est prometteuse pour étendre les interventions des praticiens, elle se concentre sur les compétences socio-émotionnelles d'enfants autistes légers. Pourtant, les interventions courantes ciblent le spectre entier au travers de nombreux aspects, dont la perception sensorielle. Partant de ce constat, j'ai mené 34 entretiens avec des personnes de la communauté de l'autisme pour comparer leurs besoins éventuels avec les études existantes en RE. Les résultats ont confirmé que certaines approches demeurent sous-explorées, permis de dresser un ensemble de recommandations de conception d'environnements de RE, et encouragé à plus explorer les approches sensorielles et de médiation. Pour considérer l'autisme modéré à sévère, la RA semble également plus adaptée que la RV, car permet de garder un contact avec l'environnement réel. A partir de ces résultats, deux initiatives de recherche ont été lancées au sein d'environnements cliniques en collaboration avec des praticiens.Dans la première partie de cette thèse, j'ai étudié la possibilité d'utiliser des approches sensorielles en RE pour sécuriser des enfants autistes et renforcer leur lien avec le praticien. L'application de RA Magic Bubbles a ainsi été créée pour compléter les interventions sensorielles courantes, telles que Snoezelen et la thérapie par l'intégration sensorielle, qui sont parfois limitées en termes de flexibilité ou d'accès. Un processus de conception centrée utilisateur a été mené pour un hôpital de jour avec deux psychologues et une médecin psychiatre, puis validé avec onze praticiens. Après des tests d'acceptabilité et d'usabilité avec dix enfants avec des troubles neurodéveloppementaux, une étude de terrain de plusieurs mois avec sept enfants autistes a confirmé son potentiel de réassurance et d'interaction sociale. De plus, en utilisant la théorie ancrée, j'ai construit une catégorisation de leurs expériences qui pourrait renseigner de futures recherches en RE sur l'autisme. Pour compléter ces résultats, deux applications de RV ont été créées, basées sur une autre intervention sensorielle, la musicothérapie. Elles explorent respectivement la performance musicale, en collaboration avec une musicothérapeute dans un conservatoire de musique, et le dialogue musical, avec les psychologues de l'hôpital de jour. Des pré-tests avec trois enfants autistes ont été positifs quant à leur acceptabilité et engagement. Afin de rendre les environnements présentés ci-dessus encore plus sécurisants, ils doivent maintenant être individualisés selon une meilleure évaluation des stimuli perçus comme négatifs ou positifs par les individus.Dans la seconde partie de cette thèse, je me suis donc concentré sur l'utilisation de la RA pour évaluer le Fonctionnement Auditif Atypique (FAA) d'enfants autistes, en collaboration avec un psychomotricien. En effet, bien que le FAA impacte fortement leur vie quotidienne, les profils sensoriels et tests auditifs actuels ne permettent pas de tester des stimuli variés dans des contextes écologiques. Ceci empêche de différencier les réactions émotionnelles et physiques par rapport aux sons et donc de développer des stratégies sensorielles appropriées. J'ai commencé par développer une taxonomie sonore représentative du FAA autistique au travers d'une revue systématique de la littérature. Je l'ai ensuite validée, hiérarchisée, et améliorée avec un questionnaire en ligne répondu par 68 personnes de la communauté de l'autisme. Une application en RA a enfin été conçue pour réaliser de telles évaluations. Des tests futurs sont prévus avec des personnes autistes dans un cabinet de psychomotricité.Cette thèse conclut en dressant des perspectives de recherches issues des résultats principaux
This thesis focuses on the design and use of Extended Reality (XR) environments for supporting autistic children regarding sensory perception.While autism XR research, ranging from Augmented Reality (AR) to Virtual Reality (VR), is promising to extend practitioners' interventions, it mainly addresses the socio-emotional abilities of children with mild autism. Yet, common interventions address the entire spectrum by targeting a range of abilities, including sensory perception. Based on these observations, I conducted 34 interviews with autism stakeholders to compare their practical needs with the literature XR uses and designs. Findings confirmed the presence of a research gap, provided a set of XR guidelines, and called for further exploration of XR sensory and mediation approaches. Furthermore, to better consider moderate to severe autism, AR seemed more suited than VR, as allowing children to keep contact with the real environment and their usual practitioner. To examine this objective, two research endeavors were conducted within clinical settings in collaboration with practitioners.In the first part of this thesis, I investigated the possibility of using sensory and mediation XR approaches to support reassurance and to reinforce the child-practitioner relationship. To that end, an AR application called Magic Bubbles was created to complement usual sensory interventions, such as Snoezelen and Sensory Integration Therapy, which are sometimes limited in terms of flexibility or access. A user-centered design process was conducted for a day hospital setting with two psychologists and one psychiatrist, and validated by a clinical team of eleven practitioners. After acceptability and usability testing with ten children with neurodevelopmental disorders, a long-term field study with seven autistic children confirmed its potential for reassurance and social interaction. Moreover, using a grounded theory approach, I built a categorization of children's experiences, which could inform future autism XR research. To complement these findings, VR was explored to extend another type of sensory intervention called music therapy. Two applications were created which respectively focus on the music performance in collaboration with a music therapist at a music conservatoire, and the music dialogue in collaboration with two psychologists at the day hospital. Preliminary tests with three autistic children were positive in terms of their acceptability and engagement. In order to make the multisensory XR spaces previously presented even more reassuring, they must be adapted based on a better assessment of the stimuli inducing negative or positive experiences among autistic individuals.In the second part of this thesis, I thus focused on using AR to assess the Atypical Auditory Functioning (AAF) of autistic children, in collaboration with a psychomotor therapist. Indeed, although AAF largely impacts the everyday life of autistic people, current sensory profiles and auditory exams prevent practitioners from testing various auditory stimuli in ecological settings. This makes it hard to differentiate between emotional and physical reactions towards sounds, and thus to develop appropriate sensory strategies. To address this issue, I started by developing a sound taxonomy being representative of autistic AAF through a systematic literature review. The items of the taxonomy were then validated, ranked, and enhanced, through an online questionnaire answered by 68 stakeholders. At last, an AR application was designed to perform such assessments. Future field tests are planned with autistic individuals at the therapist's office.The thesis concludes by drawing research perspectives based on the main research findings

This study investigates the effects on self-concepts of high school students who experienced an eight week outdoor education program. Specifically, multidimensional measures of self-concept were used to compare group and gender effects across the duration of the program as well as a follow-up period of eight weeks. Literature generally supports the assumption that outdoor education programs are effective for enhancing self-concepts of participants, although empirical research reports mixed results. This study uses a participation group (N=60) and a comparison group (N=58). The participation group (31 girls, 29 boys) consisted of Year 10 students who experienced the eight week outdoor education program which included residential living activities, farm work, outdoor camping and adventure components, as well as meditative and community development activities. The comparison group (24 girls, 34 boys) consisted of Year 10 students who continued normal school schedules for the duration of the outdoor program period. A Non-Equivalent Control Group Design (Campbell & Stanley, 1963) was employed, using the Self-Description Questionnaire-II (SDQ-II) self-concept measurement instrument (Marsh, 1990). The SDQ-II measures 11 scales and a total score. Data were collected concurrently for both participation group and comparison group at each of three stages (immediately prior to outdoor program, at conclusion of outdoor program, and eight weeks after conclusion of outdoor program). A repeated measure analysis of variance (ANOV A) was conducted for the participation group, for each of the eleven scales and total score of SDQ-II. Results for the participation group showed a significant increase in three self-concept scales (Parent Relations, Emotional Stability, General School) and Total Score and a significant decrease in scores for Same-Sex Relations scale, across the duration of the outdoor program. No significant retention effects were found for the follow-up period, while Total Score for this period significantly decreased. Gender differences within the participation group indicated boys' self-perceptions of Physical Appearance and Emotional Stability were significantly influenced more these same scales for girls, as a result of participation in the outdoor program. A repeated measures multivariate analysis of variance (MANOVA) was conducted for participation and comparison groups, for each of the eleven scales and total score of SDQ-II. Results comparing self-concept measure of participation and comparison groups reported five significant effects, all favouring the comparison group (Physical Appearance, Same-Sex Relations, General School, General Self, Total Score), across the duration of the outdoor program. These comparative group results indicate the outdoor program at best had no significant positive effects on the participants, both for the duration of the outdoor program and the follow-up period. Results of gender effects comparing all boys with all girls in the study supported empirical research which reports adolescent self-concept differences are generally consistent with gender stereotypes. Significantly higher scores in this study were found for boys in three scales (Physical Appearance, Emotional Stability, Math). Generally speaking, this study has found that a one-off outdoor experience of a long duration had no significantly positive results for the participants, for multidimensional measures of self-concept. Results from this study also indicate that consistent gender stereotypes for adolescent self-concept were not significantly influenced by participation in the outdoor program. Review of relevant research in this study highlights the need for robust research design and methodology. This will enable research in this area to be more validly compared and discussed. The scarcity of empirical research concerning retention effects and gender effects in outdoor education has been identified in this study, indicating needs for future research in these areas.

Purpose: Low citizen adoption rates jeopardize the success and proliferation of e-government systems. This study aims to understand how the perception of environmental sustainability (ES) can influence a citizen’s intention to use e-government systems. Design/methodology/approach: In a case study in Peru, the technology acceptance model (TAM) adoption model is extended with the construct of ES and evaluated with structural equation modeling. An 18-element, in-person survey was constructed and administered to citizens of Lima, Peru who had prior exposure to e-government systems. Findings: The results show that citizens can be positively influenced to adopt e-government systems if they perceive that doing so will contribute to ES. Research limitations/implications: As this was a preliminary study, further research should focus on specific, as opposed to general, e-government systems, as well as encompassing a broader cross section of the population. Practical implications: Administrators of e-government initiatives can consider public-interest factors, alongside of the common self-interest factors, when looking to improve adoption rates of e-government systems. Originality/value: This is the first time that TAM has been extended with the construct of ES.

Previous research has established a relationship between exercise and cognition, with more emphasis on this ascertained link, being made on the effects of long term and endurance exercise on cognition. However, enhanced worker effectiveness relies on a strong acute collaboration of physical and cognitive performance during task execution. As a result, the purpose of this study was to examine the acute effects of extended aerobic exercise on visual perception, working memory and motor responses, and to achieve this 24 participants (12 males and 12 females) aged between 18 and 24 participated in a 2 bout cycling exercise. The experimental condition had cycling resistance set at 60 percent of each individual’s maximum aerobic output and the control condition had zero cycling resistance, where three cognitive tasks were performed at 10 minute intervals during the cycling exercise. The results showed that exercise did not affect any significant changes on the cognitive performance measures over the entire cycling duration, as well as during the exercise phase (cycling with resistance). However, visual perception improved significantly (p<0.05) immediately after exercise. This led to the conclusion that moderate to high intensity exercise when performed for an extended duration, has selective effects on certain cognitive performance measures, with the time at which the performance is measured during the exercise being a relevant factor to be considered for maximum activation effects of the exercise.

Widespread adoption of mobile payments has not taken place despite a decade of trials in various countries based upon a mobile phone handset that does not have the technology capabilities of today’s smart phones. However, significant technology developments have led to widespread consumer adoption of smart phones and other devices that may now provide the foundation for wider consumer adoption of mobile payments. Understanding UK consumer cultural perceptions on the new phenomenon is one of the first steps to influencing purchase behaviour. This thesis is based upon a post-positivist philosophy and a social constructionist ontology that explores UK consumer perceptions of mobile payments through human cognitive and affective responses of consumer payment behaviour as these influence attitude that leads to adoption. However, UK consumer interest in mobile payments on its own is unlikely to be enough to change payment behaviour, although meeting specific payment needs can motivate consumers to amend their payment behaviour that can lead to widespread adoption. Inductive empirical research is used to explore UK consumer perceptions of mobile payments through sequential mixed methods. A questionnaire is used as the 1st research instrument with closed questions that explore various aspects of consumer interest in the mobile payments phenomenon. The key themes identified from the numerical analysis of the questionnaire data are used to guide the semi-structured interviews. Content analysis is then undertaken on the qualitative interview data from which new knowledge on consumer perceptions of mobile payments is identified. Analysis of the empirical data suggests that UK consumers have significant technology and security concerns which negatively affect consumer interest. Despite these concerns, UK consumers demonstrate interest in the mobile payments phenomenon when perceived usefulness benefits are identified. The perceived usefulness positively influences attitude that overcomes perceived risks which can lead to amended consumer payment behaviour and widespread adoption. In addition, UK consumers have a significant lack of trust towards unknown organisations as well as new market entrants although there is an increased level of trust in mobile payments provided by UK banks as well as other established organisations. This research fills an important gap in existing literature on consumer payment behaviour as it explores UK consumer cultural perceptions of the mobile payments phenomenon using smart phones and contactless consumer devices; whereas earlier consumer payment research is based upon a mobile phone handset that does not have the technology capabilities of today’s smart phones and has an Asian and Nordic cultural focus. Furthermore, this research provides UK empirical evidence that refines and extends existing research through the use of sequential mixed methods whilst adding to the understanding of UK consumer attitudes related to UK payment instruments.

For adult learners of a second language, the similarities and differences in acoustic properties between their native language and the language they are learning can affect how they perceive the sounds of the new language. How learners perceive these acoustic properties will directly affect their ability to communicate. According to the Perceptual Assimilation Model (PAM) (Best 1995), learners will perceive the sounds of a language that is new to them based on how similar or different the sounds are from the learner’s native language. Between the English and Spanish language, there are some sounds that share acoustic properties and others that show contrast. Such is the case with the stop consonants /p/, /t/, /k/, /b/, /d/, and /g/. These consonants exist in both Spanish and English, and though they are similar, there are important differences in how they should be perceived and produced. Despite the differences, these sounds are likely to be confused by L2 learners due to similarity in acoustic cues. This study will use Best’s Perceptual Assimilation Model (PAM) as a framework. It will test the L2 perception of native English-speaking adults who are L2 learners of Spanish, have spent between 18 and 24 months speaking the target language as Latter-day Saint (LDS or Mormon) missionaries in the United States, and who are also currently university students enrolled in an upper-level Spanish course. It will focus on their perception of the acoustic cue of Voice Onset Time (VOT) of stop consonants.

Les principales techniques de spatialisation sonores sont pour la plupart orientées vers la reproduction de sources ponctuelles, l’étendue reste un sujet peu exploré. Cette thèse défend l’idée que les sources étendues sont pourtant des objets expressifs pouvant significativement contribuer à la richesse des pratiques de spatialisation, notamment en musique. Nous décomposerons cette thèse en trois hypothèses. La première, auditive, postulera que les sources étendues sont pertinentes perceptivement. C’est-à-dire qu’elles offrent la possibilité de faire varier de nouveaux attributs sonores et que l’auditeur est sensible à ces variations. La seconde, analytique, proposera que la polarisation des techniques de spatialisation les plus courantes vers la source ponctuelle n’est qu’arbitraire et que d’autres modèles de sources peuvent être considérés. La troisième, opérationnelle, suggèrera qu’il est possible de créer des outils permettant aux compositeurs de manier et de s’approprier les sources étendues à des fins musicales.Pour valider ces hypothèses, nous formaliserons les propriétés auditives et musicales de ces sources puis nous proposerons des méthodes concrètes pour les analyser et les synthétiser. Ces travaux seront considérés dans le cadre de la bibliothèque HOA, un ensemble d’outils de spatialisation de bas niveau que nous avons spécialement fondé à des fins d’expérimentations. Nous décrirons les spécificités de cette bibliothèque. Nous verrons notamment comment son architecture et ses différents modules permettent d’ouvrir l’ambisonie à de nouvelles pratiques éloignées du concept de ponctualité
Mainstream spatialization techniques are often oriented towards the reproduction of point sources; extension remains a relatively unexplored topic. This thesis advocates that extended sources are yet expressive objects that could contribute to the richness of spatialization practices, especially in the field of music. We’ll decompose this thesis in three hypotheses. A perceptive one, who postulates that extended sources are perceptually relevant, i.e., that they offer the possibility of varying new sound attributes and that the listener is sensitive to these variations. An analytical one, who proposes that the most common spatialization techniques focus to point sources is arbitrary and that other source’s models can be considered. And an operational one, who suggests that it’s possible to create tools for composers so they can handle and musicalize extended objects. To confirm these hypotheses, we’ll formalize the auditory and musical properties of extended sources and we’ll propose concrete methods for their analysis and synthesis. This work will be considered as part of the HOA library, a set of low-level spatialization tools we’ve founded for the purpose of experimentation. We’ll describe the specificities of this library and see how its architecture and its different modules allow the generalization of ambisonics to new practices away of punctuality

We investigate the effect of domestic armed violence brought about by political instability on the geography of distance frictions in freight mobility and the resulting differential access of regions to global markets. The Colombian transportation system has been found to be impeded by deficiencies in landside transport infrastructure and institutions, and by fragmented political environments. The micro-level analysis of U.S.-bounded export shipping records corroborates that export freight shipping from inland regions is re-routed to avoid exposures to domestic armed violence despite greatly extended landside and maritime shipping distances. We exploit the trajectories of freight shipping from Colombian regions and spatial patterns of violent armed conflicts to see how unstable geopolitical environments are detrimental to freight shipping mobility and market openness. The discrete choice model shows that the shipping flow is greatly curbed by the extended re-routing due to domestic armed violence and that inland regions have restricted access to the global market. The perception of risk and re-routing behavior is found heterogeneous across shipments and conditional to shipment characteristics, such as commodity type, freight value and shipper sizes. The results highlight that political stability must be accommodated for improved freight mobility and export-oriented economic development in the global South.

An industry survey of a representative group of gas transport experts in the pipeline industry. This survey was undertaken primarily to define and measure their perceptions of the relative rankings of the important factors considered in purchasing compressor station equipment; this information will be used subsequently to help screen technology ideas. Secondarily, the survey was designed to obtain some insight as to the types of equipment in use, when and with what it might be replaced or extended, and what new technologies could be of interest.

Worldwide, societal norms traditionally assign distinct parenting roles to mothers and fathers, shaping their approaches and contributions to childcare. However, new fatherhood is challenging these historical perceptions of parenting by redefining and highlighting men’s capacity to provide nurturing and equally enriching care to young children as women. As this review will show, recent research indicates that the positive impact of engaged fathering extends beyond simply benefiting children and fathers themselves; it also positively affects their partners, communities, and workplaces. To achieve an equal sharing of care, men must step into these roles and become actively engaged fathers who are committed to challenging traditional gender norms and proactively participating in all aspects of caregiving.

Annual plants have developed a range of different mechanisms to avoid flowering (exposure of reproductive organs to the environment) under adverse environmental conditions. Seasonal environmental events such as gradual changes in day length and temperature affect the timing of transition to flowering in many annual and perennial plants. Research in Arabidopsis and additional species suggest that some environmental signals converge on transcriptional regulation of common floral integrators such as FLOWERING LOCUS T (FT). Here we studied environmental induction of flowering in the model legume Medicago truncatula. Similarly to Arabidopsis, the transition to flowering in M. truncatula is hastened by long photoperiods and long periods of vernalization (4°C for 2-3 weeks). Ecotypes collected in Israel retain a vernalization response even though winter temperatures are way above 4°C. Here we show that this species is also highly responsive (flowers earlier) to mild ambient temperatures up to 19°C simulating winter conditions in its natural habitat. Physiological experiments allowed us to time the transition to flowering due to low temperatures, and to compare it to vernalization. We have made use of natural variation, and induced mutants to identify key genes involved in this process, and we provide here data suggesting that an FT gene in M.truncatula is transcriptionally regulated by different environmental cues. Flowering time was found to be correlated with MtFTA and MtFTB expression levels. Mutation in the MtFTA gene showed a late flowering phenotype, while over-expressing MtFTA in Arabidopsis complemented the ft- phenotype. We found that combination of 4°C and 12°C resulted in a synergistic increase in MtFTB expression, while combining 4°C and long photoperiods caused a synergistic increase in MtFTA expression. These results suggest that the two vernalization temperatures work through distinct mechanisms. The early flowering kalil mutant expressed higher levels of MtFTA and not MtFTB suggesting that the KALIL protein represses MtFTA specifically. The desert ecotype Sde Boker flowers earlier in response to short treatments of 8-12oc vernalization and expresses higher levels of MtFTA. This suggests a possible mechanism this desert ecotype developed to flower as fast as possible and finish its growth cycle before the dry period. MtFTA and FT expression are induced by common environmental cues in each species, and expression is repressed under short days. Replacing FT with the MtFTA gene (including regulatory elements) caused high MtFTA expression and early flowering under short days suggesting that the mechanism used to repress flowering under short days has diversified between the two species.The circadian regulated gene, GIGANTEA (GI) encodes a unique protein in Arabidopsis that is involved in flowering mechanism. In this research we characterized how the expression of the M.truncatula GI ortholog is regulated by light and temperature in comparison to its regulation in Arabidopsis. In Arabidopsis GI was found to be involved in temperature compensation to the clock. In addition, GI was found to be involved in mediating the effect of temperature on flowering time. We tested the influence of cold temperature on the MtGI gene in M.truncatula and found correlation between MtGI levels and extended periods of 12°C treatment. MtGI elevation that was found mostly after plants were removed from the cold influence preceded the induction of MtFT expression. This data suggests that MtGI might be involved in 12°C cold perception with respect to flowering in M.truncatula. GI seems to integrate diverse environmental inputs and translates them to the proper physiological and developmental outputs, acting through several different pathways. These research enabled to correlate between temperature and circadian clock in M.truncatula and achieved a better understanding of the flowering mechanism of this species.

Objective: To compare the performance of popular machine learning algorithms (ML) in mapping the sensorimotor cortex (SM) and identifying the anterior lip of the central sulcus (CS). Methods: We evaluated support vector machines (SVMs), random forest (RF), decision trees (DT), single layer perceptron (SLP), and multilayer perceptron (MLP) against standard logistic regression (LR) to identify the SM cortex employing validated features from six-minute of NREM sleep icEEG data and applying standard common hyperparameters and 10-fold cross-validation. Each algorithm was tested using vetted features based on the statistical significance of classical univariate analysis (p<0.05) and extended () 17 features representing power/coherence of different frequency bands, entropy, and interelectrode-based distance. The analysis was performed before and after weight adjustment for imbalanced data (w). Results: 7 subjects and 376 contacts were included. Before optimization, ML algorithms performed comparably employing conventional features (median CS accuracy: 0.89, IQR [0.88-0.9]). After optimization, neural networks outperformed others in means of accuracy (MLP: 0.86), the area under the curve (AUC) (SLPw, MLPw, MLP: 0.91), recall (SLPw: 0.82, MLPw: 0.81), precision (SLPw: 0.84), and F1-scores (SLPw: 0.82). SVM achieved the best specificity performance. Extending the number of features and adjusting the weights improved recall, precision, and F1-scores by 48.27%, 27.15%, and 39.15%, respectively, with gains or no significant losses in specificity and AUC across CS and Function (correlation r=0.71 between the two clinical scenarios in all performance metrics, p<0.001). Interpretation: Computational passive sensorimotor mapping is feasible and reliable. Feature extension and weight adjustments improve the performance and counterbalance the accuracy paradox. Optimized neural networks outperform other ML algorithms even in binary classification tasks. The best-performing models and the MATLAB® routine employed in signal processing are available to the public at (Link 1).

Previous research on ride-hailing has focused on the effects that the built environment, demographic variables, and personal attitudes have on the frequency of ride-hailing use, finding that adopters are mainly young and highly educated people with increased levels of technology embracement. Despite that some scholars have shown that the convenience of ride-hailing such as their flexibility and major geographical coverage has led to users to prefer services provided by Transportation Network Companies (TNCs) over public transportation for some trips, there is a lack of research on how perceptions of public transit systems and TNCs can induce ride-hailing usage. In this article we extend the understanding of ride-hailing phenomena by proposing that structural gaps in public transit are key explanatory variables in the uptake and willingness to pay for ride-hailing trips. Building on an international survey in Mexico City, Bogotá, and Medellín, we develop a Structural Equation Model (SEM) incorporating latent variables expressing perceptions people have about features of ride-hailing and vulnerabilities in public transit. Results show that these variables are relevant. We also confirm that educational attainment and income are instrumental for ride-hailing trips, and that technology embracement is the most important variable to distinguish among levels of adoption. Findings inform public policy by focusing on the negative experiences of using public transit and how this could be generating more ride-hailing trips. TNCs are an attractive transport alternative that can fill gaps in public transit systems but that are also benefiting from structural problems in the transit systems.

Most people in low-income countries contribute substantially to the financing of local public goods through informal revenue generation (IRG). However, very little is known about how IRG works in practice. We produce novel evidence on the magnitude and regressivity of IRG and its relationship with the state in a fragile context, Somalia. We rely on original data from surveys with over 2,300 households and 117 community leaders in Gedo region, as well as on extensive qualitative research. We first show that IRG is prevalent. Over 70 per cent of households report paying at least one informal tax or fee in the previous year, representing on average 9.5 per cent of annual income. We also find that, among households that contribute, poorer ones contribute larger amounts than richer ones, with higher incidence in relation to their income. Further, in line with theory and expectations, informal payments have inequitable community-level effects, with individuals in wealthier communities making more informal payments than in poorer ones and, correspondingly, having access to a greater number of public goods. We then consider four explanations for the prevalence of IRG. First, IRG clearly fills gaps left by weak state capacity. Relatedly, we show that IRG can bolster perceptions and legitimacy of the state, indicating that sub-national governments may actually benefit from informal taxation. Second, informal taxing authorities are more effective tax collectors than the state, with informal taxing authorities having greater legitimacy and taxpayers perceiving informal payments to be fairer than those levied by the state. Third, dispelling the possibility that informal payments should be classified as user fees, taxpayers overwhelmingly expect nothing in return for their contributions. Fourth, in contrast to hypotheses that informal payments may be voluntary, taxpayers associate informal payments with punishment and informal institutions of enforcement. Our research reinforces the importance of IRG to public goods provision in weak formal institutional contexts, to everyday citizens, and to policymakers attempting to extend the influence of the federal state in south-central Somalia. Foremost, informal tax institutions need to be incorporated within analyses of taxation, service delivery, social protection, and equity. At the same time, our findings of the complementary nature of IRG and district-level governance and of the relative efficiency of revenue generation by local leaders have important implications for understanding statebuilding processes from below. Indeed, our findings suggest that governments may have little incentive to extend their taxing authority in some fragile contexts.

The arts do not exist in vacuum and cannot be valued in abstract ways; their value is how they make people feel, what they can empower people to do and how they interact with place to create legacy. This research presents insights across Australia and Aotearoa New Zealand about the value of arts and culture that may be factored into whole of government decision making to enable creative, vibrant, liveable and inclusive communities and nations. The COVID-19 pandemic has revealed a great deal about our societies, our collective wellbeing, and how urgent the choices we make now are for our futures. There has been a great deal of discussion – formally and informally – about the value of the arts in our lives at this time. Rightly, it has been pointed out that during this profound disruption entertainment has been a lifeline for many, and this argument serves to re-enforce what the public (and governments) already know about audience behaviours and the economic value of the arts and entertainment sectors. Wesley Enoch stated in The Saturday Paper, “[m]etrics for success are already skewing from qualitative to quantitative. In coming years, this will continue unabated, with impact measured by numbers of eyeballs engaged in transitory exposure or mass distraction rather than deep connection, community development and risk” (2020, 7). This disconnect between the impact of arts and culture on individuals and communities, and what is measured, will continue without leadership from the sector that involves more diverse voices and perspectives. In undertaking this research for Australia Council for the Arts and Manatū Taonga Ministry for Culture & Heritage, New Zealand, the agreed aims of this research are expressed as: 1. Significantly advance the understanding and approaches to design, development and implementation of assessment frameworks to gauge the value and impact of arts engagement with a focus on redefining evaluative practices to determine wellbeing, public value and social inclusion resulting from arts engagement in Australia and Aotearoa New Zealand. 2. Develop comprehensive, contemporary, rigorous new language frameworks to account for a multiplicity of understandings related to the value and impact of arts and culture across diverse communities. 3. Conduct sector analysis around understandings of markers of impact and value of arts engagement to identify success factors for broad government, policy, professional practitioner and community engagement. This research develops innovative conceptual understandings that can be used to assess the value and impact of arts and cultural engagement. The discussion shows how interaction with arts and culture creates, supports and extends factors such as public value, wellbeing, and social inclusion. The intersection of previously published research, and interviews with key informants including artists, peak arts organisations, gallery or museum staff, community cultural development organisations, funders and researchers, illuminates the differing perceptions about public value. The report proffers opportunities to develop a new discourse about what the arts contribute, how the contribution can be described, and what opportunities exist to assist the arts sector to communicate outcomes of arts engagement in Australia and Aotearoa New Zealand.
