We are in the era of multicore machines, where we must exploit thread level parallelism for programs to run better, smarter, faster, and more efficiently. In order to increase instruction level parallelism, processors and compilers perform heavy dataflow analyses between instructions. However, there isn’t much work done in the area of inter-thread dataflow analysis. In order to pave the way and find new ways to conserve resources across a variety of domains (i.e., execution speed, chip die area, power efficiency, and computational throughput), we propose a novel framework, termed Contech, to facilitate the analysis of multithreaded program in terms of its communication and execution patterns. We focus the scope on shared memory programs rather than message passing programs, since it is more difficult to analyze the communication and execution patterns for these programs. Discovering patterns of shared memory programs has the potential to allow general purpose computing machines to turn on or off architectural tricks according to application-specific features. Our design of Contech is modular in nature, so we can glean a large variety of information from an architecturally independent representation of the program under examination.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Jogos educacionais constituem em uma importante ferramenta de ensino na área de Engenharia de Software, onde, muitas vezes, os alunos não passam por nenhum mecanismo de treinamento prático. Um jogo educacional de qualidade tem que ter objetivos educacionais bem definidos, motivar os alunos e efetivar a aprendizagem dos conteúdos. A aplicação de jogos no Ensino de Engenharia de Software deve ser realizada de forma sistemática e controlada com base em avaliação. A técnica Estatística de Experimentação permite a medição e a análise das variáveis envolvidas no processo de aplicação de jogos para que estes possam ser aplicados com qualidade. Para definir melhor os experimentos no uso de jogos para o ensino de Engenharia de Software, este trabalho propõe diretrizes para o planejamento de experimentos em jogos educacionais, de forma que permita verificar a influência e a significância da utilização desses jogos no ensino e aprendizado dos conceitos de Engenharia de Software. Um experimento com o SimulES-W foi realizado seguindo essas diretrizes, onde foi possível ser demonstrada sua aplicabilidade e simplicidade em sua definição. A experiência de uso do SimulES-W mostra que aprender com jogos de computador é divertido, interativo e que, apesar dos resultados obtidos não serem significativos estatisticamente, de certa forma contribui para o ensino da Engenharia de Software, não sendo necessariamente um conhecimento prévio do conteúdo. / Educational games constitute an important teaching tool in the area of Software Engineering, where, often, students do not pass through any mechanism for hands-on training. A quality educational game must have well-defined educational goals, motivate students and make effective learning of the content. The application of games in teaching Software engineering must be carried out in a systematic and controlled on the basis of evaluation. The statistical technique of experimentation allows the measurement and analysis of the variables involved in the process of applying for these games can be applied with quality. To further define the experiments in the use of games for teaching Software Engineering, this paper proposes guidelines for the design of experiments in educational games, in order to verify the influence and significance of the use of these games in the teaching and learning of the concepts of Software engineering. An experiment with SimulES-W was conducted following these guidelines, which may be demonstrated its applicability and simplicity in its definition. The experience of use of the SimulES-W shows that learning with computer games is fun, interactive and that, despite the results obtained are not statistically significant, somehow contributes to the teaching of Software Engineering, not necessarily a prior knowledge of the content.

Seu caráter multifacetado é tal que ainda é passível de problematização a inscrição dessa narrativa em um gênero (ou forma narrativa) definido, pois nela há rastros dos três grandes gêneros – o Lírico, o Épico (narrativo) e o Dramático – e, ainda, dentro de cada um , outras pistas que levam à percepção de variadas formas, tanto do poema, da cantiga e do cantar de gesta, quanto da epopéia, do conto e da novela; e mais ainda, do teatro e do cinema. Essa implosão de fronteiras discursivas revela a dualidade essencial da obra, sua fundação alicerçada em dois suportes: um arcaico e outro moderno, percebidos na tradição literária e na experimentação formal. O intuito, portanto, é verificar o modo como a sobreposição de planos culturais e de enredo, assim como a transposição de gêneros e de códigos artísticos mobilizam metalinguisticamente tais... / “Cara-de-Bronze” is one of João Guimarães Rosa’s most experimental narratives, for it presents a textual architecture built over several discursive layers that move implied and explicit cultural substrates related both to Western culture, as for example the medievalism and the literary tradition of medieval novels, and to Eastern-Asian culture, as the Indian Upanishads quoted as footnote. Its multi-facial characteristic is so intense that inserting this narrative into a defined genre (or narrative form) comes to a problem, because there are traces of the three great genres – Lyric, Epic, and Tragedy – in it, and, yet, inside each of them, other clues that reveal the perception of several forms, both from poetry, from folk songs or chanson de geste, and from the epopee, from the short-stories and from the novella; and, furthermore, from theater and cinema. This implosion of discursive boundaries shows the work of art’s dual essence, its foundation built upon two bases: one archaic and the other modern, noticeable in the literary tradition and in the formal experimentation. The aim is, therefore, to verify how the overlaying of cultural plans and of plot, as well as the transposition of genre and artistic codes, mobilize metalinguistically the inter- and intra-discursive layers and make Rosa’s work an aesthetical experiment whose objective is pointing out the artistic process itself and the poetical effect that follow as a result. With the general aim of investigating this narrative, the analysis here developed see as relevant the theories which are based on the critical current that regards the text as an object. From the concepts of formal experimentation, discussed by Antonio Manoel dos Santos Silva (2009), a path follows based on literary French semiotics, greimasian, rethought by Denis Bertrand (2003), on cultural semiotics, from Tartu’s school, edified...

Modules for experimental lessons were proposed, based on the Science-Technology-Society (STS) teaching approach, and applied during one semester in a class of 30 undergraduate s (1st Semester 2011). The proposed didactic modules began with the presentation and discussion of documentaries with emphasis on controversial socioscientific issues, followed by an experiment of investigative character. All the conceptual topics included in these modules were originally part of the course syllabus, which were associated with the procedural and attitudinal contents emphasizing environmental and green chemistry education. The research corpus consisting of students textual production (response to questionnaires and reports) and transcript interviews (focal groups). The content analysis method was employed to describe and interpret the survey data. Also, the analysis of the experimental didactic modules using a holistic metric known as Green Star (GS) was carried out. Through the analysis of the results obtained by qualitative research in this case study, the didactic proposal enabled students to understand the contents in a complex context that included socioscientific issues, considering Green Chemistry as a mandatory demand for the initial teacher training. / O presente estudo teve como objetivo principal o desenvolvimento, adaptação e análise da inserção de práticas de laboratório com ênfase à Química Verde em uma disciplina de caráter experimental do primeiro ano do curso de Licenciatura em Química do Departamento de Química da Universidade Federal de São Carlos (DQ-UFSCar). Módulos para aulas experimentais foram propostos, baseados na abordagem de ensino CTS, e aplicados no decorrer de um semestre junto uma turma de 30 licenciandos do curso de interesse (1o. Semestre de 2011). A proposta de ensino estudada iniciou-se com uma aula expositiva dialogada (apresentação e discussão de reportagens ou documentários com ênfase às problemáticas sociocientíficas controversas), seguida pela realização do experimento de caráter investigativo, que compreendia os conteúdos conceituais inicialmente contidos na ementa da disciplina, associados aos conteúdos procedimentais e atitudinais voltados às questões ambientais e da Química Verde. O corpus da pesquisa foi constituído pela produção textual discente (resposta aos questionários e relatórios) e transcrição de entrevistas. A análise de conteúdo foi a metodologia empregada para descrever e interpretar os dados da pesquisa. Também neste trabalho realizou-se uma análise do grau verde das experiências aplicadas, usando como instrumento uma métrica holística, a Estrela Verde (EV). Por meio da análise dos resultados obtidos pela pesquisa qualitativa pautada em um estudo de caso foi possível observar que as experiências executadas possibilitaram aos estudantes compreender os conteúdos abordados e considerar a Química Verde como um eixo a ser adotado no ensino da Química.

The objective of this work was to evaluate the action of the lactic bacterias of two commercial marks of fermented milks, one cultivated with Lactobacillus paracasei (L1) and other with Lactobacillus casei (L2), on the weight gain and hematologic and histopathologic parameters of rats Wistar making the indomethacin use. The choice of the drug based on the hypothesis of the existence of the protection of the digestive system and of the histology of the organs of the animals against the possible aggression of the nonsteroidal anti-inflammatory for the concomitant administration of the fermented milks. Three lots of each fermented milk were used, taking place the count of the viability of the lactic bacterias, gram coloration, catalase and morphologic identification. Simultaneously, 60 rats Wistar males with 90 days, consuming commercial ration and water ad libitum, were divided in 6 groups of 10, being the group LP added of L1; LP + D of L1 + drug; C (control) of water; D, of drug; LC, of L2; and LC + D, of L2 + drug. The animals received the fermented milks (5mL/Kg/day) and/or the drug indomethacin (2mg/Kg/day) for gavage for 40 days, enrolling the weekly weights. After the sacrifice, blood samples were collected for the accomplishment of hemograms and it was verified the weight of the kidneys, spleens and livers, taking place the histopathology of these organs and of the stomachs and intestines. The obtained results were treated with ANOVA, Tukey, Friedman, Duncan, Kruskall-wallis and Wilcoxon (p<0,05), being used the statistical package R. The strains of L1 and L2 resulted in catalase negative, gram positive and morphology of bacilli, presenting final counts of bacteria with superior values to 106 UFC. The fermented milks added to the diets of LP and LC and the addition of the drug to D didn't influence in the weekly weight gain of the animals, but LP+D and LC+D statistically differed of C and D, suggesting there to be interaction among drug-food. In the difference among the initial and final weight of the animals, the groups that received fermented milk resembled each other to the control, except the group LP whose weight gain was inferior; D also presented deficit of weight gain in relation to the group C. The diets didn't influence in the weights of the kidneys of the experimental groups, LP just presented significant difference in terms of spleen weight in relation to the other groups and the weights of the livers of the groups LP, D and LC+D differed in relation to the control group, where D resulted in superior weight of C and LP and LC+D obtained inferior weights to the control group. In the blood parameters, the groups didn't differ to each other in the red and white series, nor in the differential leucocyte count, if not verifying immunostimulatory effects; already in the counts of the platelets, some groups presented statistical difference, however the obtained results were inside of the allowed. The histopathological analysis had not evidenced histology alterations in the stomachs, livers, kidneys and spleens, meeting discreet infiltrated of lymphoid cells in the own sheet of the intestine of the experimental groups. / Pesquisas demonstram que o consumo de leite fermentado é benéfico à saúde devido à presença de bactérias láticas e dos metabólitos produzidos por elas durante a fermentação do leite. O objetivo deste trabalho foi avaliar a ação das bactérias láticas de duas marcas comerciais de leites fermentados, uma cultivada com Lactobacillus paracasei (L1) e outra com Lactobacillus casei (L2), sobre o ganho de peso e parâmetros hematológicos e histopatológicos de ratos Wistar fazendo o uso de indometacina. A escolha da droga baseou-se na hipótese da existência da proteção do trato digestivo e da histologia dos órgãos dos animais contra a possível agressão do antiinflamatório pela administração concomitante dos leites fermentados. Foram utilizados três lotes de cada leite fermentado, realizando-se a contagem da viabilidade das bactérias láticas, coloração de gram, catalase e identificação morfológica. Simultaneamente, 60 ratos Wistar machos com 90 dias, consumindo ração comercial e água ad libitum, foram divididos em 6 grupos de 10, sendo o grupo LP adicionado de L1; LP + D de L1 + droga; C (controle) de água; D, de droga; LC, de L2; e LC + D, de L2 + droga. Os animais receberam os leites fermentados (5mL/Kg/dia) e/ou a droga indometacina (2mg/Kg/dia) por gavagem durante 40 dias, registrandose os pesos semanais. Após o sacrifício, amostras sanguíneas foram coletadas para a realização de hemogramas e verificou-se o peso dos rins, baços e fígados, realizando-se a histopatologia destes órgãos e dos estômagos e intestinos. Os dados obtidos foram tratados com ANOVA, Tukey, Friedman, Duncan, Kruskall-wallis e Wilcoxon (p<0,05), utilizando-se o pacote estatístico R. As cepas de L1 e L2 resultaram em catalase negativas, gram positivas e morfologia de bacilos, apresentando contagens finais de bactérias com valores superiores a 106 UFC/mL. Os leites fermentados adicionados às dietas de LP e LC e a adição da droga ao grupo D não influenciaram no ganho de peso semanal dos animais, mas LP+D e LC+D diferiram estatisticamente de C e D, sugerindo haver interação entre droga-alimento. Na diferença entre o peso inicial e final dos animais, os grupos que receberam leite fermentado assemelharam-se ao controle, exceto o grupo LP cujo ganho de peso foi inferior; D também apresentou déficit de ganho de peso em relação ao grupo C. As dietas não influenciaram nos pesos dos rins dos grupos experimentais, apenas LP apresentou diferença significativa em termos de peso de baço em relação aos demais grupos e os pesos dos fígados dos grupos LP, D e LC+D diferiram em relação ao grupo controle, onde D resultou em peso superior a C e LP e LC+D obtiveram pesos inferiores ao grupo controle. Nos parâmetros sanguíneos, os grupos não diferiram entre si nas séries vermelha e branca, nem na contagem diferencial dos leucócitos, não se constatando efeito imunoestimulador; já nas contagens das plaquetas, alguns grupos apresentaram diferença estatística, porém os resultados obtidos encontraramse dentro da faixa permitida. As análises histopatológicas não evidenciaram alterações na histologia dos estômagos, fígados, rins e baços, apresentando discreto infiltrado de células linfóides na lâmina própria do intestino dos grupos experimentais.

Célèbre dans l’histoire du théâtre pour avoir fondé en 1887 le Théâtre-Libre et ainsi révolutionné la mise en scène moderne, André Antoine a consacré la dernière partie de sa vie au cinéma, tournant huit films entre 1915 et 1922 pour la Société cinématographique des auteurs et gens de lettres, puis pour la Société d’éditions cinématographiques, avant de se consacrer à la critique, dramatique et cinématographique, dans plusieurs journaux. Cette dernière partie de sa vie laissa peu de traces dans l’histoire du cinéma et ses films, comme ses critiques et textes théoriques sur le cinéma, sont encore méconnus. Inspiré par les théories naturalistes d’Émile Zola, Antoine appliqua au nouvel art une méthode rigoureuse reposant sur l’expérience du milieu. Il se heurta ainsi aux tendances avant-gardistes qui gagnèrent le cinéma au début des années 1920. Or, c’est l’intérêt de cette valeur expérimentale de son cinéma, où priment la recherche, l’observation et l’expérience, que cette thèse met en lumière, en montrant les réseaux de convergence entre la méthode singulière d’Antoine et les pratiques et discours qui animèrent le cinéma au tournant de la Première Guerre mondiale, moment clef de sa légitimation en tant qu’art. Cette étude repose sur une analyse approfondie des films d’Antoine, de ses archives personnelles, des archives de production, et des nombreux écrits qu’il a produits sur le cinéma, entre 1915 et 1928, année de rupture dans un combat pour la reconnaissance de l’auteur de film qui opposa le metteur en scène aux cinéastes de la Première vague. / André Antoine’s place in theatre history is earned through his 1887 founding of the Théâtre-Libre and revolutionizing of modern mise en scène, but it is cinema that occupied the last part of his life as he made eight films between 1915 and 1922 for the Société cinématographique des auteurs et gens de lettres (“Film Society of Authors and Men of Letters”) and then for the Société d’éditions cinématographiques (“Society of Film Editions”), before devoting himself to theatre and film critic in several newspapers. These late years left few traces in film history, and both his films and his critical and theoretical writings remain largely unknown. Inspired by Emile Zola’s naturalist theories, Antoine took to the new art form a rigorous method based on the experience of environment. He clashed with avant-garde trends which were making their way to cinema in the early 1920s. This thesis highlights the experimental value of Antoine’s cinema, which gives a special role to research, observation and experience, by demonstrating the convergence of his special method with practices and discourse animating cinema at the turn of the World War I, a key moment of its legitimation as an art form. This study is based on in-depth analysis of Antoine’s films, his personal archives, production notes, as well as numerous texts he wrote on cinema between 1915 and 1928, the climactic year in the struggle for authorship recognition between Antoine and filmmakers of the First avant-garde.

Le "gold-standard" du traitement chirurgical des scolioses est l'arthrodèse, qui consiste, à l'aide d'une instrumentation adaptée, à corriger et redresser les déformations scoliotiques, puis fusionner les vertèbres du segment pathologique afin de consolider la correction réalisée. Cette fusion entraine la destruction de la biomécanique physiologique du rachis, en supprimant sa mobilité et sa croissance. Les travaux réalisés dans le cadre de cette thèse portent sur le développement et la validation d'un nouveau concept d'instrumentation rachidienne ayant pour objectifs de réduire voire d'arrêter l'évolution des déformations rachidiennes, en conservant croissance et mobilité. Ce nouveau dispositif a nécessité une étude biomécanique large, partant du concept nouveau de cet implant, passant par la mise au point d'une méthodologie expérimentale, la conception et la réalisation de prototypes, puis leur validation à travers des études numériques, mécaniques, tribologiques et in vivo sur gros animal. La caractérisation in vitro du dispositif porte sur des essais mécaniques de caractérisation de matériau et des essais tribologiques de caractérisation du frottement. La caractérisation in vivo consiste en deux études menées sur gros animal, le modèle de porc Landrace, une première sur l'étude de l'arrachement de vis pédiculaires, puis une seconde, de validation de concept, avec 2 mois d'implantation du montage. Les premières conclusions tirées de ces travaux sont positives quant au bon fonctionnement du système. Des études en cours et à venir permettront de compléter ces résultats, et de valider le système dans son ensemble, afin de permettre sa future mise sur le marché. / The "gold standard" of surgical treatment of scoliosis is arthrodesis, which, with an appropriate instrumentation, corrects and straightens the deformities and fuses the vertebra of the pathologic segment to consolidate the correction. This fusion leads to the destruction of the physiological biomechanics of the spine, destroying growth and mobility. The work done in this thesis focuses on the development and validation of a new concept of spinal instrumentation which objectives are to reduce or even stop the development of spinal deformities, maintaining growth and mobility. This device is composed of materials used in new ways, leading to friction issues that do not exist in the current spinal systems. Thus, the system required a large biomechanical study, starting from the new concept of this implant, carrying on the development of an experimental methodology, designing and prototyping and then validation through numerical, mechanical, tribological and large animal in vivo studies. In vitro characterization of the device involves characterization of material through mechanical tests, and characterization of the tribological behavior of the system. In vivo characterization consists of two studies on large animal, the Landrace pig model : a first one on pedicle screws pullout, and a second one with 2 months of implantation, to validate the concept. The initial findings from this work are positive about the correct behavior of this system. Ongoing and future studies will complement those results, and validate the system as a whole, to allow future marketing.

Les vis pédiculaires sont largement utilisées pour l’instrumentation et la correction du rachis. L’objectif général de ce projet doctoral est d’étudier l'influence des choix chirurgicaux et des variations morphologiques des vertèbres sur l'ancrage biomécanique des vis pédiculaires. Pour cela, nous avons fait le choix de combiner une modélisation détaillée de l’interaction vis-vertèbre à l’acquisition de données expérimentales indispensables pour valider les outils de simulation. Ce projet doctoral propose un modèle par éléments finis original et innovant prenant en compte l’interface de contact entre les structures osseuses et un comportement élastoplastique avec modélisation de la fracture osseuse pour décrire la biomécanique de l’interaction vis-pédiculaire/vertèbre. De plus, ce projet a également permis de proposer un protocole et une méthode d’analyse pour l’étude de vis pédiculaires sous chargements non-axiaux. Les connaissances développées au cours de ce projet doctoral ont permis de fournir des recommandations pratiques pour les cliniciens ainsi que les développeurs d’implants biomédicaux, autant sur les futurs choix de design des vis pédiculaires que les choix de vis et leur placement afin d’obtenir un meilleur ancrage. À long terme, le modèle pourrait être adapté pour analyser plus en détail les caractéristiques spécifiques du patient et être utilisé comme une formation virtuelle ou d'un outil de planification préopératoire. / The pedicle screws are widely used for instrumentation and correction of the spine. The general objective of this doctoral project is to investigate the influence of surgical choice and morphological changes in the vertebrae on the biomechanical anchorage of pedicle screws. A combined approach using a detailed numerical model to simulate the screw-vertebrae interaction and the acquisition of necessary experimental data to validate the numerical tool was chosen. This doctoral project proposes an original and innovative finite element model taking into account the contact interface between the bone structures and an elastoplastic behavior with bone fracture modeling to describe the biomechanics of the screw / vertebra interaction. In addition, this project also propose a protocol and a method of analysis for the study pedicle screws in non-axial loads. The knowledge developed during this doctoral project have provided practical recommendations for clinicians and developers of biomedical implants, both on future choices of design pedicle screws that screw choice and placement to obtain better anchoring. In the long term, the model could be adapted to further analyze the specific characteristics of the patient and be used as a virtual training or a preoperative planning tool.

Notre travail est une contribution à l’élaboration d’un cadre de recherche pour étudier le développement institutionnel pour la cogestion des ressources halieutiques communes, qui reste un mode de gouvernance minoritaire à l’échelle mondiale malgré ses impacts positifs démontrés dans de nombreux cas concrets. Spécifiquement, la thèse examine la performance de la gouvernance de petites pêcheries suivant une approche empirique et inductive d’économie institutionnelle. Notre démarche de recherche-action a accompagné des interventions de politiques publiques des pêches sur la gestion de ressources récifales surexploitées dans plusieurs cas d’étude en Nouvelle-Calédonie et au Vanuatu (Pacifique sud) entre 2008 et 2016. Ces cas correspondaient à des contextes et des échelles spatiales et temporelles variables. La thèse s’appuie sur un modèle causal théorique des effets de ce type d’intervention sur le changement institutionnel dans les petites pêcheries, et sur une grille d’évaluation de la dynamique du développement institutionnel dans les cas d’étude. Elle propose une exploration à la fois analytique et pratique de l’expérimentation adaptative du développement de systèmes de cogestion en conditions réelles. Différentes sources de connaissances, académiques et non académiques, sont mobilisées, sur les petites pêcheries et sur l’apprentissage de leur gouvernance partagée. Les résultats montrent que la gestion spatialisée et multiéchelle des pêcheries récifales par cycles de fermetures et d’ouvertures temporaires de la pêche constitue une forme d’hybridation de la gestion communautaire et de l’intervention gouvernementale, adaptée à de nombreuses pêcheries mono ou plurispécifiques du Pacifique sud. Quatre processus clés soustendant la performance économique des régimes de cogestion des pêcheries étudiées sont mis en évidence : l’apprentissage individuel des processus systémiques, l’apprentissage collectif, l’homogénéisation des stratégies des acteurs, et le renforcement des capacités d’action. Ces processus opèrent de manière interdépendante et selon leur propre temporalité, en réponse aux aléas et aux contingences des pêcheries, qui déterminent notamment les conditions initiales des interventions. En abordant explicitement les questions de durabilité des petites pêcheries à l’échelle nationale et en même temps à l’échelle locale opérationnelle de gestion, la démarche de recherche adoptée propose des pistes de recherches effectivement transdisciplinaires sur la cogestion des petites pêcheries et sur ses capacités à mieux répondre aux enjeux de durabilité. / This work is a contribution for elaborating a research framework for the study of institutional development for the comanagement of common fishery resources. Indeed this governance mode is marginally being used worldwide despite its positive impacts that have been proved in a large number of concrete cases.Specifically the thesis examines the performance of the governance of small-scale fishery through an empirical and inductive approach of institutional economics. Our action research framework guided interventions of public fishery policy on the management of overexploited marine resources in several case studies in New Caledonia and Vanuatu (South Pacific) between 2008 and 2016.Those cases corresponded to different contexts and temporal and spatial scales. The thesis is supported i) by a theoretical causal model of the effects of this kind of intervention on institutional change in smallscale fisheries, and ii) by an evaluation grid of the dynamics of institutional development in the case studies. It analytically and practically explores the process of adaptive experimentation of co-management development in reallife conditions. Academic and non academic knowledge on small-scale fisheries and the learning through shared governance is mobilized.Results show that spatial, multi-scale management of reef fisheries through temporary openings and closures of fishing is a way to combine community-based management and government intervention that is relevant for a number of single- and multi-species fisheries in the South Pacific. Four key processes that drive the economic performance of fishery co-management regimes are highlighted, namely individual learning of systemic processes, collective learning, homogenization of actors’ strategies, and building of capacity for action.These processes are interdependent following their own temporality in response to multiple stresses and fishery contingencies, that determine the initial conditions of the interventions in particular. By explicitly taking into account sustainability problems of smallscale fisheries at both the national and the local, operational levels, our researchframework proposes truly transdisciplinary research guidelines on the co-management of small-scale fisheries and on its capacity for addressing sustainability challenges more efficiently.
