Abstract:

Cet article présente et discute certains résultats spécifiques provenant d’une étude plus large qui visait à explorer le rapport qu’entretiennent les consommateurs responsables aux biens de consommation. Sur la base de données empiriques collectées auprès de citoyens qui se sont tournés vers des modes de consommation à moindres impacts écologiques, il a été remarqué que l’adoption d’habitudes de « consommation durable » n’est pas seulement motivée par des considérations altruistes et environnementales, mais également par des bénéfices personnels et/ou familiaux perçus, incluant une augmentation attendue du bien-être. Ces dernières motivations, ainsi que la manière avec laquelle elles s’expriment à travers des préférences pour certaines caractéristiques que présentent des produits de consommation, sont exposées. Tout en reconnaissant les dangers que peuvent représenter la définition et la valorisation d’une approche de la consommation responsable qui se limite aux profits et intérêts individuels, l’article suggère que la compréhension de tels motifs, et leurs implications pour la manière dont les produits et services sont conçus et positionnés, demande à être davantage explorés et compris en vue de, potentiellement, supporter un avenir davantage durable.

Abstract:

L’analyse linguistique de la fréquence itérative (vs singulative) entraîne l’augmentation de la perspective du point de vue du personnage, ou une limitation de la perspective du point de vue du narrateur. La perception linguistique ne se limite pas à une saisie perceptuelle hic et nunc: avec l’itératif, des temporalités diverses sont compactées, favorisant une augmentation du savoir de l’énonciateur, ce qui complexifie l’analyse des sources évidentielles (origine du savoir) dans les récits, relativisant les approches ontologiques de l’omniscience narratoriale et de la restriction de champ actorielle.

Abstract:

A certificate is evidence of participating in a process, and anyone who holds a certificate is believed to have the prerequisites necessary to handle what the certificate qualifies them for. However, this perception might be incorrect if the certificate has been obtained by taking shortcuts. [Objective] In this paper, a compartmental model was developed to quantify factors that could put the authenticity of a certificate in doubt by examining the trade-off between academic standards and failure rates in the context of tertiary education institutions in Nigeria. [Methodology] The model was validated using several mathematical theorems. Equilibria for the model and the threshold for acceptable academic performance were derived. Stability analysis was carried out by using the stability theory of differential equations based on the derived acceptable academic performance threshold. [Results] The theoretical results for the model were validated through numerical simulations, and the results from the simulations linked acceptable failure rates to academic performance falling below the threshold of the institutions’ standards. [Conclusions] The policy implication of the result is that an increase in the supply of qualified graduates into Nigeria’s labor markets, as well as a reduction in the rate of unemployment, is a function of maintaining academic standards.

Abstract:

L’article porte sur la question de la préservation des sols face à leur consommation pour l’urbanisation. En dépit d’une législation qui pousse de plus en plus à la sobriété foncière, l’artificialisation des sols se poursuit à un rythme élevé en France. Les approches par la reconnaissance des services écosystémiques sont développées pour améliorer la préservation des ressources naturelles. Ces approches arrivent-elles à infléchir la consommation des sols lorsqu’elles sont appropriées par les élus locaux ? Quelle est la diversité des perceptions des services écosystémiques et des stratégies de développement des élus locaux ? À travers le concept de services écosystémiques, nous analysons les représentations et les usages des sols des élus pour six territoires périurbains français. En croisant les discours sur les services écosystémiques des sols et leur consommation effective, nous montrons la limite d’une approche normative des services écosystémiques pour la régulation des usages des sols.

Abstract:

RésuméLa notion d’espace intérieur, dès lors qu’elle ne se limite plus aux lieux physiques de l’intimité pour être transférée à l’intériorité, acquiert un caractère métaphorique qui en rend la saisie à la fois plus riche et plus difficile. L’espace intérieur, s’il a pour socles les modifications de la cosmologie, de la géographie, de la physiologie de la perception, de la perspective, correspond à un réaménagement des rapports de la conscience au monde. Dès lors des analogies s’établissent entre les espaces physiques et d’une part les réalités mentales et spirituelles, d’autre part les formes et les genres littéraires. Les paysages d’âme quêtent pour l’homme un nouvel habitat.

Abstract:

Dans leurs activités quotidiennes, les pauvres de Nairobi passent sans arrêt de l’informel à l’illégal. La limite n’est pas marquée. Dans l’optique de la survie, les deux sphères d’activité ne sont pas clairement différenciées. La perception de ce qui est illégal et de ce qui ne l’est pas par les différents groupes sociaux et par les autorités varie aussi beaucoup suivant l’espace et les circonstances. Ce sont pourtant des normes édictées par les uns et par les autres qui sous-tendent les relations sociales tissées entre les gens d’en bas et l’Etat. Ces relations montrent l’arbitraire et l’incohérence de la loi et de la façon dont elle est appliquée.

Abstract:

Les comportements suicidaires chez les personnes présentant une déficience intellectuelle ou un trouble du spectre de l’autisme sont peu reconnus et ont été peu étudiés, ce qui limite le développement d’interventions adéquates. Cet article propose une analyse des connaissances et des besoins dans ce domaine, à partir d’une synthèse des connaissances scientifiques et un forum de consultation d’experts en recherche et en clinique. Les résultats montrent qu’il est important de reconnaître l’existence des comportements suicidaires chez ces personnes, de développer les connaissances sur les liens entre permanence de la mort, perception du temps, communication et suicidalité chez ces personnes et d’analyser le besoin de développer ou d’adapter des stratégies d’estimation du risque.

Abstract:

La recherche présentée trouve son origine dans une double problématique : d'une part la mise en évidence de l'addiction au cannabis et d'autre part le lien articulant l'addiction au cannabis et les aménagements caractériels de la personnalité limite ("névrose de caractère" et "psychose de caractère"). Dans ce cadre, nous avons formulé l'hypothèse selon laquelle l'estime de soi, l'implication comportementale, le système d'activité et la représentation du discours social définissent le type d'aménagement caractériel du sujet addict au cannabis ("névrose de caractère" et "psychose de caractère"). La première phase de notre recherche est la caractérisation de notre échantillon. Notre population se compose de 70 sujets addicts au cannabis, sélectionnés selon des critères d'inclusion précis : questionnaire de dépendance au cannabis, Addiction severity index et critères de la personnalité limites selon le DSM IV. La seconde phase explore notre hypothèse générale à partir de l'estime de soi, de l'implication comportementale, du système d'activité et de la représentation du discours social. Pour tester notre hypothèse et ses liaisons, nous avons utilisé comme outils d'évaluation la Self esteem iventory, le Hand test, la Telic dominance scale et l'entretien semistructuré. En effet, l'estime de soi, le système d'activité et la représentation du discours social sont des composantes discriminatives des sujets addicts au cannabis de notre échantillon. L'implication comportementale est faiblement significative pour pouvoir différencier les sujets addicts au cannabis selon leurs aménagements caractériels. En conclusion, nous pouvons dire que l'aménagement caractériel du sujet addict au cannabis a une influence sur la consommation du cannabis. L'addiction au cannabis est contrôlée si l'aménagement caractériel est de type "névrose de caractère" ; par contre elle sera renforcée si l'aménagement de caractère est de type "psychose de caractère"
The research presented originates in a double set of problems : on the one hand revelation of cannabis addiction and on the other hand the link between cannabis addiction and borderline personality adaptation ("character neurosis" and "character psychosis"). With this aim in mind, we hypothesized that self esteem, behavioral involvement, activity system and representation of the rules and expectations of society define the type of personality adjustment of cannabis addict ("character neurosis" et "character psychosis"). The first phase of our research consisted of characterization of the sample. Our population consisted of 70 cannabis addict selected according to precise inclusion criteria (the cannabis dependency questionnaire, the Addiction severity index and criteria of bordreline personnahty according to the DSM IV). The second phase investigated our general hypothesis based on self-esteem, behavioral involvement, activity system and representation of the rules and expectations of society. In order to test our hypothesis and its correlations, we used the following evaluation tools : the Self esteem inventory, Hand test, the Telic dominance scale and the semi-structured interview mode. Self esteem, activity system and representation of the rules and expectations of society are in fact discriminant components of the cannabis addicts in our sample. Behavioral involvement was weakly significant in differentiating cannabis addicts according to personality adjustment. In conclusion, the personality adjustment of the cannabis addict, has an influence on cannabis consumption. Cannabis addiction is controlled if personality adjustment is of "character neurosis" type, but on the other hand addiction will be reinforced if the adjustment is of "character psychosis" type

Abstract:

Bien que le narcissisme, la psychopathie et le machiavélisme soient trois construits distincts, la recherche montre qu’ils présentent certains chevauchements. Ces trois construits de personnalité, qui sont considérés comme aversifs sans nécessairement atteindre un seuil pathologique, forment la « triade noire » (TN; « dark triad »). Chacun de ces construits de personnalité implique à divers degrés des comportements d’autopromotion, une froideur émotionnelle, une tendance à la tromperie et à l’agressivité (Paulhus et Williams, 2002). Chez les adolescents de la communauté, les traits de personnalité de la TN, plus particulièrement la psychopathie et le machiavélisme, sont associés à la présence de délinquance et de symptômes d’agression (Muris, Meesters et Timmermans, 2013). De plus, les trois construits de la TN sont associés à des déficits au niveau de la cognition sociale, notamment un déficit d’empathie. Une meilleure compréhension de la relation entre la triade noire et la cognition sociale pourrait contribuer à améliorer les interventions auprès d’adolescents présentant ces traits de personnalité. De plus, puisque la plupart des études sur la TN ont été menées auprès d’adultes, il subsiste des lacunes au niveau des connaissances quant à l’expression de ces traits de personnalité et leurs relations chez les adolescents.

Abstract:

Une question philosophique cruciale dans la philosophie contemporaine de la perception est de déterminer quelles sont les choses que nous pouvons percevoir, par opposition aux choses auxquelles nous ne pouvons que penser. Dans cette thèse, je défends une vision "libérale" de la perception qui accepte que nous puissions percevoir certains types de contenus dits de haut niveau. Je propose un argument original basé sur la description d'un mécanisme psychologique pertinent qui confère une telle capacité de représentation que j'appelle la schématisation. La schématisation décrit un processus par lequel les systèmes perceptifs (je me concentre sur la vision) structurent de manière représentationnelle leurs entrées sensorielles, en donnant la priorité à certaines de leurs dimensions, et en activant implicitement (ou amorçant) des représentations similaires stockées dans la mémoire perceptive. La schématisation est un processus purement perceptif qui nous permet de représenter des contenus, que j’appelle les aspects, qui ne sont pas réductibles à des contenus dits de bas niveau. Les aspects représentent certaines propriétés de haut niveau des objets. Ils représentent les objets comme ayant une forme physique qui les fait appartenir à un type superficiel, tel que le type superficiel de la forme d'un chat ou d'une chaise. Il est essentiel de noter que les aspects ne peuvent pas représenter des propriétés de types naturel ou fonctionnel comme le fait d’être un chat ou d’être une chaise, car ces propriétés dépendent de caractéristiques non visibles des objets, situées sous leur surface. Je soutiens donc que des considérations empiriques minutieuses sur les capacités représentationnelles de la perception justifient un libéralisme modéré qui n'admet que ces aspects représentant des propriétés de type superficiel comme contenu de niveau supérieur de la perception. Les aspects sont aussi haut que les yeux peuvent voir
A philosophically crucial question within contemporary philosophy of perception is to determine what things we can perceive, as opposed to things we can only think about. In this thesis, I defend a “liberal” view of perception which accepts that we can perceive some kinds of high-level contents. I propose an original argument based on describing a relevant psychological mechanism that grants such representational capacity that I call schematization. Schematization describes a process by which perceptual systems (I focus on vision) representationally structure their sensory inputs, prioritizing certain feature dimensions, and implicitly activate (or prime) similar representations stored in perceptual memory. Schematization is a purely perceptual process that allows us to represent contents that are not reducible to low-level contents: aspects. Aspects represent some high-level kind properties of particulars. They represent particulars as having some physical body form that makes them belong to a superficial kind, such as the superficial kind of cat-form or chair-form. Crucially, I argue that aspects cannot represent natural or functional kind properties like cat-hood or chair-hood, since such properties depend on below-surface, non-visible characteristics of objects. I thus argue that careful empirical considerations about the representational capacities of perception vindicate a moderate Liberalism that only admits aspects representing superficial kind properties as the higher-level contents of perception. Aspects are as high as eyes can see

Older adults represent a segment of population that has more increased in recent years. In Brazil, estimates for next 20 years indicate that elderly population will exceed 30 million people, which can reach nearly 13% of population. Regular physical activity provides one of most opportunities for improving quality of life, improve physical condition and reduce disability and functional limitations of elderly people. The increasing of elderly population has raised need to understand changes that occur in this stage of life, as well as their implications, since, during aging, there are several physiological changes that can affect perception of food for older consumers. For these reasons, present study aimed to evaluate taste sensitivity in elderly people practitioners of physically active, since little is known about sensory responses provided by this group. Threshold test was used to determine detection threshold for salty and sweet flavors in 40 young adults (18-38 years), 40 elderly practitioners of regular physical activity (60-84 years) and 40 elderly no activity practitioners physical (60-87 years). Women accounted for 90% in the group of elderly practitioners of physical activity and 60% of non-elderly practitioners, feature explained by aging feminization process. Physically active elderly had 4.12 mMol thresholds for salty and 6.20 mMol for sweet taste, values close to the group of young adults surveyed and below values found in other studies that worked with sensory perception in the elderly. There were significant minimization of sensory changes of salty and sweet taste in elderly practitioners of physical activity, providing to this group sensorial perception capacity similar to young adults group. Physical activity contributes in some ways to the best development of sensorial perception of older people who practice physical activity, a positive factor for both active development of that group and to its perceptual capacity.
Indivíduos da terceira idade representam um dos segmentos da população que mais tem aumentado nos últimos anos. No Brasil, as estimativas apontam para os próximos 20 anos que a população idosa irá exceder 30 milhões de pessoas, o que pode chegar a representar quase 13% da população. A atividade física regular proporciona uma das maiores oportunidades para se melhorar a qualidade de vida, melhorar as condições físicas e reduzir a incapacidade e limitações funcionais dos idosos. O crescente aumento da população idosa vem despertando a necessidade de se compreender as mudanças que ocorrem nessa fase de vida, bem como suas implicações, uma vez que, durante o envelhecimento, ocorrem diversas transformações fisiológicas que podem afetar a percepção de alimentos por consumidores idosos. Por esses motivos, o presente estudo teve como objetivo avaliar a sensibilidade gustativa em idosos praticantes de atividade física, uma vez que pouco se sabe sobre as repostas sensoriais fornecidas por esse grupo. Foi utilizado o teste de limite para determinar os limiares de detecção para os sabores salgado e doce, em 40 adultos jovens (18-38 anos), 40 idosos praticantes de atividade física regular (60-84 anos) e 40 idosos não praticantes de atividade física (60-87 anos). As mulheres representaram 90% no grupo dos idosos praticantes de atividade física e 60% dos idosos não praticantes, característica explicada pelo processo de feminilização do envelhecimento. Os idosos praticantes de atividade física apresentaram limiares de 4,12 mMol para o gosto salgado e 6,20 mMol para o gosto doce, valores estes próximos aos do grupo dos adultos jovens pesquisados e abaixo dos valores encontrados em outros estudos que trabalharam com percepção sensorial em idosos. Houve minimizações significativas das alterações sensoriais do gosto salgado e doce em idosos praticantes de atividade física, proporcionando a este grupo capacidade de percepção sensorial semelhante à de adultos jovens. A atividade física contribui de certa forma no melhor desenvolvimento da percepção sensorial dos idosos que praticam atividade física, sendo um fator positivo tanto para o desenvolvimento ativo desse grupo como para sua capacidade perceptiva.

O objetivo central desse trabalho é entender as reais possibilidades de participação de elementos subliminares no processo de persuasão publicitária. Para isso, o modelo AIDA foi utilizado em conjunto com estudos científicos que evidenciam e esclarecem as reações de um indivíduo exposto a estímulos subliminares utilizados como estímulos preparatórios para a recepção de estímulos conscientes.
The main goal of this research is to clarify the actual limits of subliminal elements in advertising persuasiveness.

Abstract:

La thèse défendue dans de document commence par un examen des approches d'évaluation de performances dans le cadre de la perception artificielle, et comment elle se rapporte aux limites ( et l'inévitable subjectivité) de la spécification de la vérité terrain. Elle établit qu'il existe une ambiguïté intrinsèque dans son interprétation et son analyse, notamment dans le cadre de l'analyse du document de l'image. Après avoir établi le fait que l'interprétation est nécessairement ambigüe et que cette ambiguïté provient essentiellement de l'existence différents contextes plus ou moins compatibles, notre objectif global est d'étudier si on peut: * établir une forme de description du contexte qui est adaptée à la perception artificielle ( et de l'analyse de documents en particulier) et si elle peut être obtenue automatiquement par des techniques d'apprentissage statistique ou formelle ; * utiliser la description du contexte pour évaluer les performances d'algorithmes ; * utiliser la description de contexte pour décrire les données, de sorte à ce que cette description peut être utilisée pour des applications de recherche d'information ; * établir des limites ou des restrictions formelles pour les descriptions décrites précédemment et déterminer s'il existe des interprétations qui sont prouvablement impossibles à être obtenues par un algorithme. S'il existe effectivement une classe de problèmes d'interprétation qui ne peuvent pas être résolus par un algorithme, la seconde question serait de savoir si cette classe peut être caractérisée d'une façon ou d'une autre.

Abstract:

The factors that limit human endurance have received extensive scientific scrutiny. Traditionally these limiting factors have been attributed to physiological processes occurring within the muscles, the cardiovascular system, or spinal and supraspinal sites. Consequently, interventions designed to provoke alterations in endurance performance are generally tailored towards targeting these physiological processes. Recent research suggests that endurance performance is also limited by psychobiological influences: specifically perception of effort (RPE). On this basis the psychobiological model of endurance performance predicts that any physiological or psychological factor affecting RPE will alter endurance performance. As such, this thesis sought to elicit alterations in RPE, and consequently physical endurance, using psychobiological strategies that were implemented to directly target RPE. In Chapter 2 it was established that a two week motivational self-talk intervention significantly reduced RPE at 50% iso-time while enhancing cycling time to exhaustion (TTE) by 18%. This equated to a very likely beneficial practical effect on TTE (beneficial/trivial/harmful%; 99/1/0%). In Chapter 3, a six week cognitive training protocol was designed to repeatedly target the anterior cingulate cortex due to its neuro-cognitive connections with cognitive and physical effort. This approach did not significantly alter RPE or TTE at exercise intensities of 80% or 65% peak power output (PPO). A likely beneficial practical effect on TTE was nonetheless evident at 65% PPO (83/15/2%). Using subliminal affective priming in Chapter 4, RPE was significantly lower and TTE significantly greater when participants were subliminally primed with happy faces while cycling compared to an alternative visit when they were subliminally primed with sad faces. This difference in TTE was of possible practical value (70/30/0%). Following on from this, Chapter 5 implemented a single subject approach using a randomization tests design and illustrated that subliminally primed action words significantly reduced RPE and enhanced TTE compared to subliminally primed inaction words.

Abstract:

Réduit à sa plus simple expression, ce travail de recherche met face à face deux acteurs s’affrontant dans un duel philosophique : le physicalisme et l’argument de la connaissance de Franck Jackson. La question clé autour de laquelle s’agencera notre discussion ici est (1) Est-il vrai que « Tout est physique » ? Le coeur de la thèse que nous défendons peut être résumé ainsi : (T) Le clivage post-platonicien (tacite) entre les formes objectivées et les formes subjectivées de la pensée, provoque des fossés explicatifs (explicites), qui sont franchis (très souvent) via des sauts conceptuels (mystérieux), intercalés entre les étapes d’une argumentation. Il sera argumenté ici que la distribution actuelle des débats sur l’axe états physiques (objectifs) / états qualitatifs (subjectifs) subit une pression souterraine post-platonicienne. Conséquemment, une bonne partie de l’énergie des penseurs actuels est dépensée à la recherche du « bon saut » ou « crochet » conceptuel permettant d’attacher les rives du mental à celui du physique. Nous soutiendrons que le coeur du problème ne consiste pas à résoudre le différend entre les physicalistes et les avocats des qualia, mais plutôt à trouver la réponse à la question : pourquoi en sommes-nous arrivés là, i.e., à ce clivage sur l’axe phénoménal/physique ?
“Everything is physical” physicalists claim. “Everything except qualia” reply the defenders of the Knowledge Argument. This thesis argues that both parties to this debate are committed to a traditional picture according to which one can tacitly adopt the standpoint of an off-stage narrator, capable of distinguishing ab initio between the different items in this conceptual scenario. The main claim here is that every time we artificially introduce a sharp conceptual distinction separating these two items or levels (mental and physical), we must automatically make a sophisticated conceptual leap in order to link the first-person qualitative perspective with the external physical world. Thus the physicalism/qualia dispute is only a by-product of an extended theoretical conception of the mind/world link which entails two distinct kinds of problems: (i) structural problems (to define and determine conceptually dual items like thought/matter, reason/senses, subject/object, etc.). Such problems require us to question “how are these items supposed to work together?” and this leads us to the second group of problems: (ii) mediation problems. The first group of problems inevitably leads to explanatory gaps; the second ends up needing to appeal to conceptual leaps in order to ensure the necessary link between two separate items. This exerts a powerful influence over the cast of our thoughts: seen from this angle, all philosophical enterprise comes down to the question of where to place the three following parameters: the world as it is, the conceptual picture which aims to represent the world as it is and the theorist-painter gifted with the ability to capture the world picture as it is. We also face the problem of finding the right mediators to assure coherence among the members of this trio, and the problem of setting the valid criteria guaranteeing the theorist-painter that what is captured on his conceptual canvas does indeed correspond to the world as it is, i.e. that he is not laboring under the delusions of an evil genie. In this thesis I argue against this way of putting things

AbstractThis chapter defends the view that empathy is tightly linked to the concept (and the phenomenon) of moral perception, which is in turn closely related to moral judgement. The contributions of scholars such as Lawrence Blum are taken into account and carefully analysed in order to demonstrate how moral judgement needs moral perception and how in turn moral perception cannot function properly without empathy.

Abstract:

AbstractThe chapter discusses the perceptions and constructions of Asia in the Mongol period, focusing on two travellers going eastward in the thirteenth and fourteenth centuries: William of Rubruck and Ibn Battuta. By reconstructing the context and motivations for their voyages, the author traces European and Arab perceptions of East Asia and Inner Asia as they emerge from two key travel reports. Particular attention is given to the scope and limit of their curiosities, exploring similarities and differences in both mental attitude and perception of Asian spaces. The scholarly concept of othering so often applied to travellers entering the East is here questioned and problematized. Interestingly, social imageries of Asia often went beyond quoting ancient authorities and repeating known tropes of classical and holy texts. This finding in turn sparks questions about the relationship between changing narratives, mobilities, and agendas behind the production of knowledge.

Abstract:

Flight testing has been performed on a Royal Canadian Air Force (RCAF) CH-147F Chinook helicopter to investigate aircrew whole-body vibration (WBV) exposure levels in accordance with ISO 2631-1 or MIL-STD-1472G standard. Results showed that the helicopter cabin vibration was dominated at the N/rev harmonics of the three-bladed tandem rotor speed. The aircrew WBV levels varied significantly depending on flight conditions and aircraft load configurations while the highest levels of WBV occurred at high speed level flight maneuver conditions. With reference to the guidelines in the standards, the aircrew WBV exposure level in the entire tested flight profile was qualitatively rated as "uncomfortable", and the maximum duration of such missions should be limited to ensure compliance with the limit of the "Vibration Health Risks Guideline Caution Zone". The aircrew subjective perception survey for this flight profile also confirmed an increase of personnel ride discomfort.

Abstract:

Le paysage, d’un point de vue sémiotique, est un ensemble figuratif producteur de valeurs : valeurs différentielles et valeurs visées par une énonciation. L’enjeu, en l’occurrence, est de comprendre comment les valeurs différentielles, saisies dans un acte de perception, sont converties en valeurs narratives et discursives, visées par une énonciation. Cela suppose entre autres que l’on comprenne ce que peut être l’ « énonciation » d’un paysage, et, plus généralement les « instances » actantielles qui le constituent comme sémiotique-objet.L’étude proposée ne prétend pas à la généralisation, car elle se limite à un corpus de paysages limousins, et elle repose sur un mouvement qui va du plan de l’expression au plan du contenu.En partant de l’analyse plastique, on peut montrer en effet comment se mettent en place les opérateurs énonciatifs (la lumière, l’atmosphère, l’horizon) et les acteurs du débrayage et de l’embrayage (ciels, terres et eaux). Pour finir, l’étude détaillée des différentes formes figuratives de l’eau (lacs, fleuves et rivières) conduit à identifier une médiation de type « mythique », où les formes aquatiques assurent la transition entre les paradigmes célestes et terrestres.

Abstract:

The European Union (EU) is doubling down on its efforts to strengthen the civilian dimensions of its Common Security and Defence Policy (CSDP) and increase the effectiveness of its civilian crisis management missions. Two thematic areas that received stronger attention in the newly updated Civilian CSDP Compact in May 2023 are gender equality and strategic communications. Yet in civilian CSDP missions, overlap between these areas—which come together as ‘gender-responsive strategic communications’—remains limited. There has also only been limited research on the overlap between gender expertise and communications in peace operations and crisis management missions. This SIPRI Policy Brief explores the opportunities and challenges of gender-responsive strategic communications in the context of EU civilian CSDP missions. It provides six recommendations which align with ongoing processes towards improving capability development, gender parity, counter-foreign information manipulation and interference (FIMI), and training. The recommendations address formal guidance, accountability mechanisms, contextual awareness in missions, men in gender work, women’s participation and gendered FIMI threats.

Abstract:

The aim of the study was to explore the impact of furniture and spatial settings on teachers and students. Drawing on a case study action research approach involving surveys, two primary schools (Frangipani and Jasmine Primary School) within the Sydney Catholic Schools were involved as case study sites. This report provides a summary of the findings of the impact of furniture and spatial settings on teacher efficacy, teacher mind frames, student learning and student engagement as well as perceptions of students on the furniture and spatial settings. In summary, teachers’ perceptions of their mind frames, student learning and engagement increased after the introduction of furniture in the prototype learning environment. For one teacher, the perception of their efficacy did not improve after the implementation of the prototype space and furniture. In terms of students’ perceptions of the furniture, a large proportion of students agreed that they enjoyed learning and are more motivated to learn because of the new furniture. At Jasmine Primary School, a fifth of students felt that they were not motivated to learn because of the new furniture. Further in-depth study is required to find out the underlying reasons for this. Key themes that emerged from the qualitative data on the furniture and spatial settings focus on characteristics of furniture that afforded comfort, improved concentration and auditory qualities, supported collaboration, and capacity for choice. These are important considerations to drive decisions in school designs and furniture purchases. The importance of good furniture in a learning space cannot be underestimated. New learning environments and furniture demand and create new possibilities for teacher practices and student learning. The findings of the study, whilst limited in its scale, provides three crucial considerations relating to the importance of prototyping, professional learning and longitudinal data. These carry ramifications for wider understanding and future research. Future inquiry in these three key areas can provide the much-needed evidence to support schools’ transition into new learning environments.

La technologie peut améliorer le recouvrement des impôts dans trois domaines, notamment l’identification de l’assiette fiscale, le contrôle de la conformité et la facilitation de la conformité. Cependant, même la technologie la plus conviviale ne peut fonctionner sans une infrastructure de base et une connexion internet stable. Les avantages potentiels des nouvelles technologies sont en outre entravés par la résistance des contribuables et des percepteurs, par un environnement réglementaire peu favorable et par l’absence de stratégie d’adoption par les institutions.

Full text

Abstract:

As a public agency, interacting with and understanding the public’s perspective regarding agency activities is an important endeavor for the Indiana Department of Transportation (INDOT). Although INDOT conducts a biennial customer satisfaction survey, it is occasionally necessary to capture public perception regarding more specific aspects of INDOT’s activities. In particular, INDOT needs an effective way to measure and track public opinions and awareness or understanding of a select set of its traffic engineering practices. To evaluate public acceptance of specific INDOT traffic engineering activities, a survey consisting of 1.000 adults residing within the State of Indiana was conducted. The survey population was representative in terms of age and gender of the state as of the 2010 U.S. Census. The survey was administered during the months of July and August 2020. Public awareness regarding emerging treatments not currently implemented in Indiana is low and opposition to the same new technologies is prominent. Older or female drivers are less likely to be aware of emerging treatments, and older drivers are more likely to oppose potential implementation of these treatments. Although roundabouts are commonplace in Indiana, multi-lane roundabouts remain controversial among the public. Regarding maintenance and protection of traffic during work zones and considering full or partial roadway closure, public preference is for partial closure; this preference is stronger in rural areas. The public equally agrees and disagrees that INDOT minimizes construction related traffic delays. Approximately 76% of Indiana drivers believe themselves to above average drivers, while an additional 23% believe themselves to be average. Driver perceptions of average highway speeds speed are not aligned with posted speed limit as the perceived average speed on Indiana’s urban freeways and rural and urban state highways is considerably higher than the actual speed limit.

Full text

Abstract:

Numerous studies have emerged so far on Covid-19 (SARS-CoV-2) across different disciplines. There is virtually no facet of human experience and relationships that have not been studied. In Nigeria, these studies include knowledge and attitude, risk perception, public perception of Covid-19 management, e-learning, palliatives, precautionary behaviours etc.,, Studies have also been carried out on public framing of Covid-19 discourses in Nigeria; these have explored both offline and online messaging and issues from the perspectives of citizens towards government’s policy responses such as palliative distributions, social distancing and lockdown. The investigators of these thematic concerns deployed different methodological tools in their studies. These tools include policy evaluations, content analysis, sentiment analysis, discourse analysis, survey questionnaires, focus group discussions, in depth-interviews as well as machine learning., These studies nearly always focus on the national government policy response, with little or no focus on the constituent states. In many of the studies, the researchers work with newspaper articles for analysis of public opinions while others use social media generated contents such as tweets) as sources for analysis of sentiments and opinions. Although there are others who rely on the use of survey questionnaires and other tools outlined above; the limitations of these approaches necessitated the research plan adopted by this study. Most of the social media users in Nigeria are domiciled in cities and their demography comprises the middle class (socio-economic) who are more likely to be literate with access to internet technologies. Hence, the opinions of a majority of the population who are most likely rural dwellers with limited access to internet technologies are very often excluded. This is not in any way to disparage social media content analysis findings; because the opinions expressed by opinion leaders usually represent the larger subset of opinions prevalent in the society. Analysing public perception using questionnaires is also fraught with its challenges, as well as reliance on newspaper articles. A lot of the newspapers and news media organisations in Nigeria are politically hinged; some of them have active politicians and their associates as their proprietors. Getting unbiased opinions from these sources might be difficult. The news articles are also most likely to reflect and amplify official positions through press releases and interviews which usually privilege elite actors. These gaps motivated this collaboration between Ekiti State Government and the African Leadership Centre at King’s College London to embark on research that will primarily assess public perceptions of government leadership response to Covid-19 in Ekiti State. The timeframe of the study covers the first phase of the pandemic in Ekiti State (March/April to August 2020).

Full text

Abstract:

There is an existing issue in human-machine interaction, such that drivers of semi-autonomous vehicles are still required to take over control of the vehicle during system limitations. A possible solution may lie in tactile displays, which can present status, direction, and position information while avoiding sensory (e.g., visual and auditory) channels overload to reliably help drivers make timely decisions and execute actions to successfully take over. However, limited work has investigated the effects of meaningful tactile signals on takeover performance. This study synthesizes literature investigating the effects of tactile displays on takeover performance in automated vehicles and conducts a human-subject study to design and test the effects of six meaningful tactile signal types and two pattern durations on drivers’ perception and performance during automated driving. The research team performed a literature review of 18 articles that conducted human-subjects experiments on takeover performance utilizing tactile displays as takeover requests. Takeover performance in these studies were highlighted, such as response times, workload, and accuracy. The team then conducted a human-subject experiment, which included 16 participants that used a driving simulator to present 30 meaningful vibrotactile signals, randomly across four driving sessions measuring for reaction times (RTs), interpretation accuracy, and subjective ratings. Results from the literature suggest that tactile displays can present meaningful vibrotactile patterns via various in-vehicle locations to help improve drivers’ performance during the takeover and can be used to assist in the design of human-machine interfaces (HMI) for automated vehicles. The experiment yielded results illustrating higher urgency patterns were associated with shorter RTs and higher intuitive ratings. Also, pedestrian status and headway reduction signals presented shorter RTs and increased confidence ratings compared to other tactile signal types. Finally, the signal types that yielded the highest accuracy were the surrounding vehicle and navigation signal types. Implications of these findings may lie in informing the design of next-generation in-vehicle HMIs and future human factors studies on human-automation interactions.

Full text

Abstract:

We examine how investors’ perception of bank balance sheet risk evolved before and during the March-April 2023 bank run. To do so, we estimate the covariance (“beta”) of bank excess stock returns with returns on factors constructed from long-short portfolios sorted on shares of uninsured deposits and unrealized losses on securities. We find that the market’s perception of bank risk shifted in both the time series and the cross-section. From January 2022 to February 2023, both factor betas were mostly insignificant, but after the bank run started, they became positive and significant for all banks on average. However, in the cross-section, only the factor betas of banks put on downgrade watch on March 13 were significant, consistent with our finding that this announcement was informative. When additional banks were downgraded in April, their factor betas also became significant, even though we find the April announcements to be noninformative for these banks. We suggest that investors with limited attention focused on the banks included in the April announcements to update their priors on balance sheet risk.

[Extract] The aim of this report is to analyse public perceptions on the changing role of local government in Australia. Exploring how the Australian public views and understands the expansion of local government activity, from the Three Rs to a more expansive if still limited tier of government, offers crucial insights about the sector’s current state and future direction. This report presents the findings from a new national survey of 1,350 respondents who were asked what they saw the role local government to be, what services the sector should deliver, and whether acting on controversial issues to do with national identity, refugee support, and climate change, for example, should be within local government’s remit.
