Learning from the lagoon: Research in development in Solomon Islands

A major challenge for international agricultural research is to find ways to improve the nutrition and incomes of people left behind by the Green Revolution. To better address the needs of the most marginal and vulnerable people, the CGIAR Research Program on Aquatic Agricultural Systems (AAS) developed the research-in-development (RinD) approach. In 2012, WorldFish started to implement RinD in Solomon Islands. By building people’s capacity to analyze and address development problems, actively engaging relevant stakeholders, and linking research to these processes, RinD aims to develop an alternative approach to addressing hunger and poverty. This report describes the key principles and implementation process, and assesses the emergent outcomes of this participatory, systems-oriented and transformative research approach in Solomon Islands.

Intercultural musical learning in the era of technology

Foreign students abroad need to feel integrated in the new community, which includes complex learning processes in multicultural environments. The fact that we have experienced these processes ourselves was certainly a motivation for this research, especially knowing that we could contribute to help our fellow Portuguese brass players undergoing the same experience. From the singularity of music performance in the style of playing and communication emerge many cultural aspects, which have been developed through centuries of orchestral practice. As the new students are confronted with the aesthetic musical concepts and both professional and social practices of the country they arrive in, they strive to understand these concepts and adapt themselves to the values promoted by the new music practice. The aim of this on-going research is the study of the integration of brass music students in German universities and in the German society. Notably, through the understanding of intercultural processes experienced by the students, professors can become more aware of the challenges that concern music education. In this research all ten Portuguese brass students enrolled in any German music university in the last five years were interviewed in order to deeply understand this process. With a growing importance of the technological facilities, students are able to gather more information, to prepare themselves for the new concepts they try to embrace and to better deal with a different culture.

The interaction factor as a challenge for foreign language learning in the technology based education: a pedagogical reflection

The author carries out a pedagogical reflection on how the technology driven distance learning repeatedly neglects the scientific achievements of Second Language Acquisition and Language Pedagogy. Seeing communicative competence as a major goal of a language classroom, she presents the main challenges that the communicative approach poses to distance learning. To this end, a general distance learning theory by Moore is adapted to the needs of language education, through a distinction between three aspects of learner interaction – with the teacher, with other learners and with content. In this three-dimensional paradigm the learner is seen as the main actor of the process, the teacher as a facilitator, the text as a main source of communicative data and the learner autonomy as the fundament of the process.

On the brink of madness: Leituras do tema da loucura na obra pré-heteronímica de Fernando Pessoa

O tema da loucura na obra pessoana tem sido objecto de várias aproximações interpretativas, decorrentes da multiplicidade de textos que fazem eco do fenómeno e da sua persistência enquanto topos ao longo de praticamente toda a sua produção. Na sua acepção literal, manteve constantes interferências com a dimensão empírica do autor sobretudo quando sustentadas na contingência de certos textos basilares, os quais têm vindo a ser questionados quanto ao seu valor estritamente testemunhal. Como fenómeno desde cedo relacionado com a criação artística, a loucura surge neste estudo não apenas na representatividade da condição distintiva do sujeito criador mas ainda como figuração da contingência que envolve qualquer acto criativo que tome a linguagem na sua dimensão essencialmente metafórica e ambígua. Neste sentido, o presente trabalho pretende a abertura de várias vias de leitura do fenómeno através da análise crítica dos vocabulários relativos a diferentes âmbitos e concepções de loucura e a sua relação com o génio (capítulos I e II), focando o seu interesse no que diz respeito a alguma produção pessoana pré-heteronímica, nomeadamente Charles Robert Anon, Alexander Search (capítulo III) e Jean Seul de Méluret (capítulo IV), a que acrescentaremos o Primeiro Fausto (capítulo IV), de modo a conseguirmos estabelecer uma possível relação entre as primeiras experiências de alterização e a descoberta simultânea da irredutibilidade do discurso literário face a tentativas de literalização e de racionalização da linguagem, defendidas por outros modelos (paradigma biologista). A identificação da ambiguidade e da ironia nas suas mais variadas acepções como componentes essenciais da aprendizagem do valor contingente do processo de criação contribuirá tanto para a definição da autonomização da literatura como para a redescrição moderna do sujeito criador, paradoxalmente investido do pathos criativo anunciado no Romantismo e confrontando-se com os seus limites, que corresponderão aos da própria linguagem, situação de crise de que a figuração do louco lúcido será um dos tópicos mais produtivos. ABSTRACT: The theme of madness in the Pessoa work has been the subject of several interpretive approaches, from the multiplicity of texts that echo the phenomenon and its persistence as a topos priority over virtually all its production. ln its physiological sense, remained constant interference with the empirical dimension of the author when sustained in the contingency of certain basic texts that have been questioned as to their strictly testimonial value. As early phenomenon associated with artistic creation, the madness in this study is not only representative in the distinctive condition of the subject creator but also as the contingency figuration involving any creative act to take the language mainly in its essential metaphorical and ambiguous dimension. Accordingly, this work intends to open several analysis manners of the phenomenon through critical analysis of vocabularies for different areas and concepts of madness and its special relationship with the genius (Chapters I and II), focusing its interest in respect to some of the previous-heteronomy Pessoa production, including Charles Robert Anon, Alexander Search (Chapter III) and Jean Seul de Méluret (Chapter IV), and the Primeiro Fausto (Chapter IV), among others, to establish a possible relationship between changing early experiences and the discovery simultaneous literary discourse of irreducibility in the face of the attempts of literacy and the rationalization of language defended by other models (biologist paradigm). The identification of the ambiguity and irony in its many different meanings as essential components of learning the contingent value of the creation process which will contribute to the definition of empowerment in the literature as to the redescription of the modem subject creator that paradoxically had the creative pathos announced in Romanticism and from the confrontation with its limits, which will correspond to the language itself, the crisis situation from which the mad-lucid figuration will be one of the most productive topics.

VOX POPULI: THREE ESSAYS ON THE USE OF SOCIAL MEDIA FOR VALUE CREATION IN SERVICES

Prior research shows that electronic word of mouth (eWOM) wields considerable influence over consumer behavior. However, as the volume and variety of eWOM grows, firms are faced with challenges in analyzing and responding to this information. In this dissertation, I argue that to meet the new challenges and opportunities posed by the expansion of eWOM and to more accurately measure its impacts on firms and consumers, we need to revisit our methodologies for extracting insights from eWOM. This dissertation consists of three essays that further our understanding of the value of social media analytics, especially with respect to eWOM. In the first essay, I use machine learning techniques to extract semantic structure from online reviews. These semantic dimensions describe the experiences of consumers in the service industry more accurately than traditional numerical variables. To demonstrate the value of these dimensions, I show that they can be used to substantially improve the accuracy of econometric models of firm survival. In the second essay, I explore the effects on eWOM of online deals, such as those offered by Groupon, the value of which to both consumers and merchants is controversial. Through a combination of Bayesian econometric models and controlled lab experiments, I examine the conditions under which online deals affect online reviews and provide strategies to mitigate the potential negative eWOM effects resulting from online deals. In the third essay, I focus on how eWOM can be incorporated into efforts to reduce foodborne illness, a major public health concern. I demonstrate how machine learning techniques can be used to monitor hygiene in restaurants through crowd-sourced online reviews. I am able to identify instances of moral hazard within the hygiene inspection scheme used in New York City by leveraging a dictionary specifically crafted for this purpose. To the extent that online reviews provide some visibility into the hygiene practices of restaurants, I show how losses from information asymmetry may be partially mitigated in this context. Taken together, this dissertation contributes by revisiting and refining the use of eWOM in the service sector through a combination of machine learning and econometric methodologies.

The murky waters of neoliberal marketization and commodification on the education of adults in the United States

We approach marketization and commodification of adult education from multiple lenses including our personal narratives and neoliberalism juxtaposed against the educational philosophy of the Progressive Period. We argue that adult education occurs in many arenas including the public spaces found in social movements, community-based organizations, and government sponsored programs designed to engage and give voice to all citizens toward building a stronger civil society. We conclude that only when adult education is viewed from the university lens, where it focuses on the individual and not the public good, does it succumb to neoliberal forces. (DIPF/Orig.)

SARASOM: a supervised architecture based on the recurrent associative SOM

We present and evaluate a novel supervised recurrent neural network architecture, the SARASOM, based on the associative self-organizing map. The performance of the SARASOM is evaluated and compared with the Elman network as well as with a hidden Markov model (HMM) in a number of prediction tasks using sequences of letters, including some experiments with a reduced lexicon of 15 words. The results were very encouraging with the SARASOM learning better and performing with better accuracy than both the Elman network and the HMM.

Research on the BEIC Curriculum: Unveiling What Lies Under the Tip of the Iceberg

Es un detenido análisis de la investigación The Value of Curricular lntrospection, en que se incorpora la realimentación dada por diversos participantes nacionales y extranjeros en el CILAP 2007, a quienes se les expuso los resultados iniciales de esta investigación. El estudio surgió de la disparidad de criterios entre diversos actores del BEIC, de la ELCL, respecto a la pertinencia que para la enseñanza del inglés a niños en Costa Rica tienen los principios comunicativos denominados interacción, inmersión parcial y aprendizaje por experiencia. Así, mientras diseñadores de currículo y profesores del BEIC consideraban estos principios altamente eficaces, buena parte del estudiantado que realizaba la práctica docente pensaba lo contrario.A detailed analysis is provided here of the research project titled The Value of Curricular Introspection. It also includes the feedback given by the national and foreign participants in CILAP 2007, to whom this study was presented. The investigation emerged from the diverse opinions existing among BEIC-ELCL actors regarding the pertinence of interaction, partial immersion and experiential learning communicative principies for the teaching of English to children in Costa Rica. Thus, whereas BEIC curriculum designers and professors considered these principies to be highly effective, many student-teachers in that program believe just the opposite.

A Comparison of the Effects of Classroom and Multi-User Virtual Environments on the Perceived Speaking Anxiety of Adult Post-Secondary English Language Learners

The population of English Language Learners (ELLs) globally has been increasing substantially every year. In the United States alone, adult ELLs are the fastest growing portion of learners in adult education programs (Yang, 2005). There is a significant need to improve the teaching of English to ELLs in the United States and other English-speaking dominant countries. However, for many ELLs, speaking, especially to Native English Speakers (NESs), causes considerable language anxiety, which in turn plays a vital role in hindering their language development and academic progress (Pichette, 2009; Woodrow, 2006). Task-based Language Teaching (TBLT), such as simulation activities, has long been viewed as an effective approach for second-language development. The current advances in technology and rapid emergence of Multi-User Virtual Environments (MUVEs) have provided an opportunity for educators to consider conducting simulations online for ELLs to practice speaking English to NESs. Yet to date, empirical research on the effects of MUVEs on ELLs’ language development and speaking is limited (Garcia-Ruiz, Edwards, & Aquino-Santos, 2007). This study used a true experimental treatment control group repeated measures design to compare the perceived speaking anxiety levels (as measured by an anxiety scale administered per simulation activity) of 11 ELLs (5 in the control group, 6 in the experimental group) when speaking to Native English Speakers (NESs) during 10 simulation activities. Simulations in the control group were done face-to-face, while those in the experimental group were done in the MUVE of Second Life. The results of the repeated measures ANOVA revealed after the Huynh-Feldt epsilon correction, demonstrated for both groups a significant decrease in anxiety levels over time from the first simulation to the tenth and final simulation. When comparing the two groups, the results revealed a statistically significant difference, with the experimental group demonstrating a greater anxiety reduction. These results suggests that language instructors should consider including face-to-face and MUVE simulations with ELLs paired with NESs as part of their language instruction. Future investigations should investigate the use of other multi-user virtual environments and/or measure other dimensions of the ELL/NES interactions.

Student’s Perception on the Personal Impact of a Social Education Degree Internship

The functional profile of the social educator is based on the development of theoretical, technical and personal/relational skills, which should guide training courses organization. Assuming the shortcomings of a merely theoretical approach, besides a consistent preparation in theoretical and essential technical contents for socio-educational intervention, practice in context should be favoured as an opportunity to develop professional skills, together with a critical reflection on the functional profile. This study emerges from the need to reflect and rethink the internship, as well as how the respective supervision is developed, of the degree in social education at the School of Education of the Polytechnic Institute of Viseu, and it is based on the students’ perceptions about the impact of the internship on personal development. This is a qualitative and exploratory study, using the documentary analysis of 50 final internship reports. From the content analysis, four categories emerged referring to gains in terms of acquiring and managing knowledge, development of technical skills, personal and relational development and reinforcement of professional identity. The importance given to personal and relational development should be noted (41.4% of mentions) taking into account its relevance in constructing a professional identity. Findings on the technical skills and on the increase of profession knowledge, also by mobilising theoretical training, positively reinforce the internship model that is based on a proximity supervision approach and on a dialogical perspective of the professional learning.

Best-practice model for technology enhanced learning in the creative arts

This paper presents a best-practice model for the redesign of virtual learning environments (VLEs) within creative arts to augment blended learning. In considering a blended learning best-practice model, three factors should be considered: the conscious and active human intervention, good learning design and pedagogical input, and the sensitive handling of the process by trained professionals. This study is based on a comprehensive VLE content analysis conducted across two academic schools within the creative arts at one Post-92 higher education (HE) institution. It was found that four main barriers affect the use of the VLE within creative arts: lack of flexibility in relation to navigation and interface, time in developing resources, competency level of tutors (confidence in developing online resources balanced against other flexible open resources) and factors affecting the engagement of ‘digital residents’. The experimental approach adopted in this study involved a partnership between the learning technology advisor and academic staff, which resulted in a VLE best-practice model that focused directly on improving aesthetics and navigation. The approach adopted in this study allowed a purposive sample of academic staff to engage as participants, stepping back cognitively from their routine practices in relation to their use of the VLE and questioning approaches to how they embed the VLE to support teaching and learning. The model presented in this paper identified a potential solution to overcome the challenges of integrating the VLE within creative arts. The findings of this study demonstrate positive impact on staff and student experience and provide a sustainable model of good practice for the redesign of the VLE within creative disciplines.

Shaping the future of learning using the student voice: we’re listening but are we hearing clearly?

Student voice data is a key factor as Manchester Metropolitan University strives to continually improve institutional technology enhanced learning (TEL) infrastructure. A bi-annual Institutional Student Survey enables students to communicate their experience of learning, teaching and assessment on programmes and specific units studied. Each cycle of the survey contains approximately 40–50,000 free text comments from students pertaining to what they appreciate and what they would like to see improved. A detailed thematic analysis of this data has identified 18 themes, arranged into six categories relating to the ‘Best’ aspects of courses, and 25 themes, arranged in seven categories in relation to aspects of courses considered to be ‘in need of improvement’. This student data was then used as a basis for semi-structured interviews with staff. Anecdotally, evidence suggested that student expectations and staff expectations around TEL and the virtual learning environment (VLE) differed. On-going evaluation of this work has highlighted a disconnect. In significant instances, academic colleagues seemingly misinterpret the student voice analysis and consequently struggle to respond effectively. In response to the analysis, the learning technologist's role has been to re-interpret the analysis and redevelop TEL staff development and training activities. The changes implemented have focused on: contextualising resources in VLE; making lectures more interactive; enriching the curriculum with audio–visual resources; and setting expectations around communications.

Practical assessment on the run – iPads as an effective mobile and paperless tool in physical education and teaching

This paper investigates the use of iPads in the assessment of predominantly second year Bachelor of Education (Primary/Early Childhood) pre-service teachers undertaking a physical education and health unit. Within this unit, practical assessment tasks are graded by tutors in a variety of indoor and outdoor settings. The main barriers for the lecturer or tutor for effective assessment in these contexts include limited time to assess and the provision of explicit feedback for large numbers of students, complex assessment procedures, overwhelming record-keeping and assessing students without distracting from the performance being presented. The purpose of this pilot study was to investigate whether incorporating mobile technologies such as iPads to access online rubrics within the Blackboard environment would enhance and simplify the assessment process. Results from the findings indicate that using iPads to access online rubrics was successful in streamlining the assessment process because it provided pre-service teachers with immediate and explicit feedback. In addition, tutors experienced a reduction in the amount of time required for the same workload by allowing quicker forms of feedback via the iPad dictation function. These outcomes have future implications and potential for mobile paperless assessment in other disciplines such as health, environmental science and engineering.

On the Democratization of AI: Bridging the Gap with AutoML

Riding the wave of recent groundbreaking achievements, artificial intelligence (AI) is currently the buzzword on everybody’s lips and, allowing algorithms to learn from historical data, Machine Learning (ML) emerged as its pinnacle. The multitude of algorithms, each with unique strengths and weaknesses, highlights the absence of a universal solution and poses a challenging optimization problem. In response, automated machine learning (AutoML) navigates vast search spaces within minimal time constraints. By lowering entry barriers, AutoML emerged as promising the democratization of AI, yet facing some challenges. In data-centric AI, the discipline of systematically engineering data used to build an AI system, the challenge of configuring data pipelines is rather simple. We devise a methodology for building effective data pre-processing pipelines in supervised learning as well as a data-centric AutoML solution for unsupervised learning. In human-centric AI, many current AutoML tools were not built around the user but rather around algorithmic ideas, raising ethical and social bias concerns. We contribute by deploying AutoML tools aiming at complementing, instead of replacing, human intelligence. In particular, we provide solutions for single-objective and multi-objective optimization and showcase the challenges and potential of novel interfaces featuring large language models. Finally, there are application areas that rely on numerical simulators, often related to earth observations, they tend to be particularly high-impact and address important challenges such as climate change and crop life cycles. We commit to coupling these physical simulators with (Auto)ML solutions towards a physics-aware AI. Specifically, in precision farming, we design a smart irrigation platform that: allows real-time monitoring of soil moisture, predicts future moisture values, and estimates water demand to schedule the irrigation.

The “FRA wheel” as a teaching tool to elaborate on the identity aspects of physics and mathematics as disciplines in interdisciplinary contexts

This thesis project is framed in the research field of Physics Education and aims to contribute to the reflection on the importance of disciplinary identities in addressing interdisciplinarity through the lens of the Nature of Science (NOS). In particular, the study focuses on the module on the parabola and parabolic motion, which was designed within the EU project IDENTITIES. The project aims to design modules to innovate pre-service teacher education according to contemporary challenges, focusing on interdisciplinarity in curricular and STEM topics (especially between physics, mathematics and computer science). The modules are designed according to a model of disciplines and interdisciplinarity that the project IDENTITIES has been elaborating on two main theoretical frameworks: the Family Resemblance Approach (FRA), reconceptualized for the Nature of science (Erduran & Dagher, 2014), and the boundary crossing and boundary objects framework by Akkerman and Bakker (2011). The main aim of the thesis is to explore the impact of this interdisciplinary model in the specific case of the implementation of the parabola and parabolic motion module in a context of preservice teacher education. To reach this purpose, we have analyzed some data collected during the implementation in order to investigate, in particular, the role of the FRA as a learning tool to: a) elaborate on the concept of “discipline”, within the broader problem to define interdisciplinarity; b) compare the epistemic core of physics and mathematics; c) develop epistemic skills and interdisciplinary competences in student-teachers. The analysis of the data led us to recognize three different roles played by the FRA: FRA as epistemological activator, FRA as scaffolding for reasoning and navigating (inhabiting) the complexity, and FRA as lens to investigate the relationship between physics and mathematics in the historical case.
