Commentary on the Engravers' Act (1735)

Legislation conferring exclusive rights, for a period of 14 years, on persons inventing and designing engravings and similar works. This was first occasion on which British copyright legislation extended to something other than literary works. The commentary describes the background to the Act, in particular the lobbying efforts of a small group of artists and engravers led by William Hogarth, and details similarities and differences which the legislation bore to the Statute of Anne 1710. The commentary suggests that, whereas the Statute of Anne essentially sought to regulate the production of the physical book, with the Engravers' Act the legislature began to articulate a more subtle distinction between the physical object and the subject of copyright protection, which was in this case, the engraved image.

Plasticity varies with boldness in a weakly-electric fish

The expression of animal personality is indicated by patterns of consistency in  individual behaviour. Often, the differences exhibited between individuals are consistent across situations. However, between some situations, this can be biased by variable levels of individual plasticity. The interaction between individual plasticity and animal personality can be illustrated by examining situation-sensitive personality traits such as boldness (i.e. risk-taking and exploration tendency). For the weakly electric fish Gnathonemus petersii, light condition is a major factor influencing behaviour. Adapted to navigate in low-light conditions, this species chooses to be more active in dark environments where risk from visual predators is lower. However, G. petersii also exhibit individual differences in their degree of behavioural change from light to dark. The present study, therefore, aims to  examine if an increase of motivation to explore in the safety of the dark, not only affects mean levels of boldness, but also the variation between individuals, as a result of differences  in individual plasticity.  Results: Boldness was consistent between a novel-object and a novel-environment situation in bright light. However, no consistency in boldness was noted between a bright (risky) and a  dark (safe) novel environment. Furthermore, there was a negative association between boldness and the degree of change across novel environments, with shier individuals  exhibiting greater behavioural plasticity.  Conclusions: This study highlights that individual plasticity can vary with personality. In  addition, the effect of light suggests that variation in boldness is situation specific. Finally,  there appears to be a trade-off between personality and individual plasticity with shy but  plastic individuals minimizing costs when perceiving risk and bold but stable individuals  consistently maximizing rewards, which can be maladaptive.

Investigating high-achieving sixth grade students' erroneous answers on the angle concept in Yozgat

The angle concept is a multifaceted concept having static and dynamic definitions. The static definition of the angle refers to “the space between two rays” or “the intersection of two rays at the same end point” (Mitchelmore & White, 1998), whereas the dynamic definition of the angle concept highlights that the size of angle is the amount of rotation in direction (Fyhn, 2006). Since both definitions represent two diverse situations and have unique limitations (Henderson & Taimina, 2005), students may hold misconceptions about the angle concept. In this regard, the aim of this research was to explore high achievers’ knowledge regarding the definition of the angle concept as well as to investigate their erroneous answers on the angle concept.

104 grade 6 students drawn from four well-established elementary schools of Yozgat, Turkey were participated in this research. All participants were selected via a purposive sampling method and their mathematics grades were 4 or 5 out of 5, and. Data were collected through four questions prepared by considering the learning competencies set out in the grade 6 curriculum in Turkey and the findings of previous studies whose purposes were to identify students’ misconceptions of the angle concept. The findings were analyzed by two researchers, and their inter-rater agreement was calculated as 0.91, or almost perfect. Thereafter, coding discrepancies were resolved, and consensus was established.

The Role of Art in Computer Game Design

Computer games are significant since they embody our youngsters’ engagement with contemporary culture, including both play and education. These games rely heavily on visuals, systems of sign and expression based on concepts and principles of Art and Architecture. We are researching a new genre of computer games, ‘Educational Immersive Environments’ (EIEs) to provide educational materials suitable for the school classroom. Close collaboration with subject teachers is necessary, but we feel a specific need to engage with the practicing artist, the art theoretician and historian. Our EIEs are loaded with multimedia (but especially visual) signs which act to direct the learner and provide the ‘game-play’ experience forming semiotic systems. We suggest the hypothesis that computer games are a space of deconstruction and reconstruction (DeRe): When players enter the game their physical world and their culture is torn apart; they move in a semiotic system which serves to reconstruct an alternate reality where disbelief is suspended. The semiotic system draws heavily on visuals which direct the players’ interactions and produce motivating gameplay. These can establish a reconstructed culture and emerging game narrative. We have recently tested our hypothesis and have used this in developing design principles for computer game designers. Yet there are outstanding issues concerning the nature of the visuals used in computer games, and so questions for contemporary artists. Currently, the computer game industry employs artists in a ‘classical’ role in production of concept sketches, storyboards and 3D content. But this is based on a specification from the client which restricts the artist in intellectual freedom. Our DeRe hypothesis places the artist at the generative centre, to inform the game designer how art may inform our DeRe semiotic spaces. This must of course begin with the artists’ understanding of DeRe in this time when our ‘identities are becoming increasingly fractured, networked, virtualized and distributed’ We hope to persuade artists to engage with the medium of computer game technology to explore these issues. In particular, we pose several questions to the artist: (i) How can particular ‘periods’ in art history be used to inform the design of computer games? (ii) How can specific artistic elements or devices be used to design ‘signs’ to guide the player through the game? (iii) How can visual material be integrated with other semiotic strata such as text and audio?

Cerâmica de Santo Antônio do Potengi: entre tradição e modernidade

In the Rio Grande do Norte, the craftsmanship is generating of economy, it involves a significant number of people and is diversified in its raw materials and particular type. As reference of the craft local, the ceramics supplied the primary necessities in the utilitarian domestic servants, acquired piety in the religious figures, were toy in infantile amusements and, finally, gained status of pure ornament. By its historical representation, the district of Santo Antônio do Potengi is considered the most important center of manufacture of craftpottery in the State. The work of the potters continues in that locality anchored between the familiar inheritance and the participation each more influential time of the public politics destined to the sector situation verified for visible alterations in the shape of the pottery from the decade of 1990 with the implantation of a cooperative destined to the collective production. We observe in this passage, that such actions in the measure where they objectify to structuralize conditions ideal to support the artisan making, do not benefit in significant way the social development them craftsmen. It is important not to lose of sight that exists some involved dimensions in this process and that these surpass the common interest for the object and the consequent economic connotation of its commercialization. They are knowledge that imply in the access to raw materials, in the peculiar of the formal aspects and productive methods, in the contextual relations organized to defend the survival of the activity

O lugar da hispanoamérica no processo de ensino-aprendizagem de espanhol como língua estrangeira no ensino secundário português

Tendo em conta um enfoque comunicativo experiencial (Fernández- Corbacho, 2014) e uma pedagogia crítica emancipatória (Jiménez Raya, Lamb & Vieira, 2007), enriquecida por enfoques multissensoriais (Arslan, 2009), é nossa intenção, com este projeto, contribuir para a implementação de práticas que espelhem as variedades linguísticas e culturais da Hispanoamérica (Liceras, 1995; Beave, 2000) na aula de espanhol como língua estrangeira no ensino secundário português. Neste estudo, através duma perspetiva metodológica de índole qualitativa, pretendemos, como ponto de partida, analisar: a) as representações de alunos portugueses sobre o lugar da Hispanoamérica no processo de ensino-aprendizagem de espanhol como língua estrangeira (Altmann & Vences, 2004; Pérez, 2003), através de inquéritos por questionário; e, ainda, b) as abordagens das variedades linguísticas e culturais do espanhol, que surgem nos manuais utilizados no ensino secundário português. Por outro lado, através de um estudo de caso (Benson, Chik, Gao, Huang & Wang, 2009), procurámos evidenciar uma mostra de possíveis boas práticas didático-pedagógicas e materiais, com vista a um trabalho sistemático e próativo com as variedades linguísticas e culturais do espanhol, baseado numa (hiper)pedagogia crítica e encarando a língua enquanto objeto manipulável e potenciador de cidadãos verdadeiramente conscientes do mundo. Para tal, criámos materiais físicos e digitais, que foram posteriormente implementados com alunos do 11º ano de escolaridade, no nível de iniciação de espanhol, num agrupamento de escolas da região de Aveiro. Os resultados mostram que práticas e materiais desta natureza poderão favorecer aprendizagens comunicativas experienciais, quanto à criação de futuros cidadãos críticos e ativos, fomentando o desenvolvimento das suas competências comunicativa plurilingue e pluricultural e duma consciência cultural crítica (Byram, Gribkova & Starkey, 2002) dos alunos, no contexto de ensino-aprendizagem do ensino secundário.

Génération de patrons de conception et restructuration de code vers un patron de conception pour Java

(POO) est l’utilisation de patrons de conception (PC). Un PC est un arrangement caractéristique de classes permettant d’offrir une solution éprouvée, tout en obtenant un code réutilisable et compréhensible. Plusieurs PC sont définis, dont 24 par la GoF [12] et plusieurs autres sont apparus par la suite. Le concept de PC est abstrait ce qui peut amener différentes interprétations. Ces différences peuvent aussi causer une mauvaise implémentation qui peut réduire les avantages d’utiliser ce patron. Ce projet consiste à concevoir un outil facilitant l’utilisation des PC. L’outil Génération et Restructuration de Patrons de Conception(GRPC) permet la génération automatique du squelette d’un patron de conception ainsi que la restructuration d’un code en le transformant structure respectant un PC. La génération et la restructuration automatique permettent d’obtenir un code uniforme et de qualité tout en respectant le patron de conception. La compréhension et la maintenance du code sont ainsi améliorées. GRPC est module d’extension pour l’environnement de développement Eclipse écrit en Java. Le code est conçu pour être facilement compréhensible et extensible. Les deux principaux objectifs de GRPC sont de restructurer (refactoring) une section de code vers l’architecture d’un patron de conception et de générer des squelettes de patrons de conception. Une interface graphique permet de guider l’utilisateur et d’aller chercher toutes les informations importantes pour le fonctionnement du logiciel. Elle permet aussi de configurer les éléments du patron de conception. Pour s’assurer de la possibilité d’effectuer une restructuration, chaque patron est associé avec une ou plusieurs règles qui analysent le code pour détecter la présence d’une structure particulière. Des procédures aident les développeurs à ajouter de nouveaux PC dans GRPC. GRPC fournit des fonctionnalités permettant d’implémenter quelques patrons de conception de la POO définis dans le livre Design Patterns : Elements of Reusable Object-Oriented Software.

"Je ne vous dirai point, mon très cher fils" Correspondance de Catherine de Charrière de Sévery 1780-1783

This dissertation examines the principles of education imbued in a three year correspondence between an eighteenth century woman and her teenage son from the French speaking region of Vaud, current day Switzerland. Despite her great respect for the literature and ideas of the new pedagogues of the Enlightenment, especially J.J. Rousseau and Mme de Genlis, Catherine de Charrière de Sévery maintained the traditional perspective of education of the Ancien Régime. To explore the concepts of education and instruction through the epistolary practice, this research is based on the corpus of 107 letters that Mme de Sévery wrote to her son Vilhelm between 1780 and 1783. Additional documents - among them Mme de Sévery’s diaries - from the particularly rich archival holdings of this aristocratic family have been used to complement her correspondence. Most previous studies on family correspondence have dealt with mothers to daughters, or fathers to sons, whereas this research is centered on letters between a mother and her son. The location of this family – Lausanne and the Pays de Vaud – provides a particular regional perspective due to two factors: immersion into a region uniformly Protestant, and the dual-influence of Germanic and French cultures. The study analyzes the educational principles that appear throughout Mme de Sévery’s letters by comparison with three literary works of the 18th century: a familiar correspondence, the Lettres du Lord Chesterfield à son fils (1776); the fundamental education treatise by J.J. Rousseau, Émile, ou de l’Éducation (1762); and a pedagogical treatise written by Mme de Genlis as an epistolary novel, Adèle et Théodore, ou lettres sur l’éducation. Using letters as the main tool to guide her son’s upbringing, Mme de Sévery highlights the moral and family values that are most important to her and leads him to find his place in society.

A Figured Worlds Perspective on Middle School Learners' Climate Literacy Development

The purpose of this study was to investigate the nature of the relationship between middle school science learners’ conditions and their developing understandings of climate change. I applied the anthropological theoretical perspective of figured worlds (Holland, Lachicotte, Skinner, & Cain, 1998) to examine learners’ views of themselves and their capacities to act in relation to climate change. My overarching research question was: How are middle school science learners’ figured worlds of climate change related to the conditions in which they are embedded? I used a descriptive single-case study design to examine the climate change ideas of eight purposefully selected 6th grade science learners. Data sources included: classroom observations, curriculum documents, interviews, focus groups, and written assessments and artifacts, including learners’ self- generated drawings. I identified six analytic lenses with which to explore the data. Insights from the application of these analytic lenses provided information about the elements of participants’ climate change stories, which I reported through the use of a storytelling heuristic. I then synthesized elements of participants’ collective climate change story, which provided an “entrance” (Kitchell, Hannan, & Kempton, 2000, p. 96) into their figured world of climate change. Aspects of learners’ conditions—such as their worlds of school, technology and media use, and family—appeared to shape their figured world of climate change. Within their figured world of climate change, learners saw themselves—individually and as members of groups—as inhabiting a variety of climate change identities, some of which were in conflict with each other. I posited that learners’ enactment of these identities – or the ways in which they expressed their climate change agency – had the potential to reshape or reinforce their conditions. Thus, learners’ figured worlds of climate change might be considered “spaces of authoring” (Holland et al., 1998, p. 45) with potential for inciting social and environmental change. The nature of such change would hinge on the extent to which these nascent climate change identities become salient for these early adolescent learners through their continued climate change learning experiences. Implications for policy, curriculum and instruction, and science education research related to climate change education are presented.

Garbage collection optimization for non uniform memory access architectures

Cache-coherent non uniform memory access (ccNUMA) architecture is a standard design pattern for contemporary multicore processors, and future generations of architectures are likely to be NUMA. NUMA architectures create new challenges for managed runtime systems. Memory-intensive applications use the system’s distributed memory banks to allocate data, and the automatic memory manager collects garbage left in these memory banks. The garbage collector may need to access remote memory banks, which entails access latency overhead and potential bandwidth saturation for the interconnection between memory banks. This dissertation makes five significant contributions to garbage collection on NUMA systems, with a case study implementation using the Hotspot Java Virtual Machine. It empirically studies data locality for a Stop-The-World garbage collector when tracing connected objects in NUMA heaps. First, it identifies a locality richness which exists naturally in connected objects that contain a root object and its reachable set— ‘rooted sub-graphs’. Second, this dissertation leverages the locality characteristic of rooted sub-graphs to develop a new NUMA-aware garbage collection mechanism. A garbage collector thread processes a local root and its reachable set, which is likely to have a large number of objects in the same NUMA node. Third, a garbage collector thread steals references from sibling threads that run on the same NUMA node to improve data locality. This research evaluates the new NUMA-aware garbage collector using seven benchmarks of an established real-world DaCapo benchmark suite. In addition, evaluation involves a widely used SPECjbb benchmark and Neo4J graph database Java benchmark, as well as an artificial benchmark. The results of the NUMA-aware garbage collector on a multi-hop NUMA architecture show an average of 15% performance improvement. Furthermore, this performance gain is shown to be as a result of an improved NUMA memory access in a ccNUMA system. Fourth, the existing Hotspot JVM adaptive policy for configuring the number of garbage collection threads is shown to be suboptimal for current NUMA machines. The policy uses outdated assumptions and it generates a constant thread count. In fact, the Hotspot JVM still uses this policy in the production version. This research shows that the optimal number of garbage collection threads is application-specific and configuring the optimal number of garbage collection threads yields better collection throughput than the default policy. Fifth, this dissertation designs and implements a runtime technique, which involves heuristics from dynamic collection behavior to calculate an optimal number of garbage collector threads for each collection cycle. The results show an average of 21% improvements to the garbage collection performance for DaCapo benchmarks.

Different Transitions towards Learning at University: Exploring the Heterogeneity of Motivational Processes

Transitions processes in higher education are characterized by new learning situations which pose challenges to most students. This chapter explores the heterogeneity of reactions to these challenges from a perspective of regulation processes. The Integrated Model of Learning and Action is used to identity different patterns of motivational regulation amongst students at university by using mixed distribution models. Six subpopulations of motivational regulation could be identified: students with self-determined, pragmatic, strategic, negative, anxious and insecure learning motivation. Findings about these patterns can be used to design didactic measures that will support students’ learning processes.

LOS RIESGOS DE DETERIORO DEL PATRIMONIO DOCUMENTAL EN AMÉRICA LATINA

La conservación preventiva se ha convertido en la única vía para salvaguardar la memoria histórica de los pueblos. Existen múltiples definiciones de conservación preventiva, lo que con frecuencia la convierten en centro de discusiones interminables, pero casi todos coincidimos en que por conservación preventiva podemos entender todas las acciones que se dirigen a disminuir el riesgo de deterioro de las colecciones. Y he aquí que el término riesgo ocupa un sitio de gran importancia para la conservación. Entendemos por riesgo la contingencia ó proximidad de un daño, en otras palabras la probabilidad de sufrir un evento peligroso ó indeseable, que en el caso del patrimonio documental se traduce en deterioro o pérdida de valores.El riesgo de deterioro de un documento, esta dado por la relación de dos aspectos, la vulnerabilidad del objeto, y las amenazas a la que está expuesto.

Prática de ensino supervisionada em Educação Pré-escolar e Ensino do 1.º Ciclo do Ensino Básico

Este documento espelha o relatório final de Prática de Ensino Supervisionada, realizado no âmbito do curso de Mestrado em Educação Pré-escolar e Ensino do 1.º Ciclo do Ensino Básico, e procura focalizar-se nas práticas realizadas em contexto de Educação Pré-escolar e de 1.º Ciclo do Ensino Básico, onde se destaca a arte como um meio pedagógico através do qual as crianças de dois níveis de ensino, Pré-Escolar e 1.º Ciclo do Ensino Básico, se apropriaram de novos conhecimentos. Assim, o tema escolhido para este estudo foi A educação pela arte: olhar, ouvir e sentir, e prendeu-se com a necessidade de familiarizar a criança com a arte, pela importância que esta assume no seu desenvolvimento pessoal, social e cultural na medida em que a construção do conhecimento se efetiva através de recursos expressivos que preconizam criação, participação e envolvimento, dando a ver e a sentir, oferecendo ainda possibilidades interpretativas. Destaca-se ainda a importância da cooperação com outros profissionais, a interação com as crianças, a reflexão sistemática antes, durante e após a ação e pesquisa contínua, com vista à melhoria das nossas práticas e do sucesso das crianças. Desta forma, pensamos na seguinte questão problema: Como explorar a arte com as crianças em situações de aprendizagem plurais, através de um objeto real e/ou imaginado, de uma forma concreta e lúdica, apelando a diversas formas de expressão artística? e estipulamos como intencionalidades: (i) compreender os olhares das crianças sobre a imaginação, (ii) conhecer as conceções que as crianças têm sobre a arte e os artistas; e, (iii) compreender a importância da Educação e Expressão Plástica para o desenvolvimento da criança. Em termos metodológicos posicionamo-nos numa abordagem qualitativa e para a recolha de dados atendemos à observação, às notas de campo, aos registos em áudio e fotográficos, e ao inquérito por entrevista. Pensamos que as experiências de aprendizagem que realizámos com as crianças contribuíram, de forma positiva, para o desenvolvimento de competências em vários domínios das diferentes áreas do conhecimento, envolvendo a arte, vivenciada em espaços plurais. As atividades realizadas despertaram nas crianças participantes a imaginação, a sensibilidade, o sentimento e a criatividade. Da análise e reflexão ao trabalho realizado conclui-se que a Arte deve ser assumida no ensino e seriamente desenvolvida, pois é de extrema importância o seu contributo na formação das crianças.
