Rare Presentation of Neurofibromatosis and Turner Syndrome in a Pediatric Patient
Authors: Gengel Natalie , Marshall Ian
Published: June 2017

Neurofibromatosis type 1 (NF1) is classically defined by the presence of multiple café-au-lait macules as one of the diagnostic criteria. Turner syndrome (TS) can also present with café-au-lait macules along with short stature. Our patient is the fifth reported with both NF1 and TS and the first who has been on growth hormone for short stature associated with TS.
The Unisa KZN Students’ Perspectives of Student Success
Authors: Phewa Nombulelo Molly Cynthia
Published: June 2017

This paper aims to present what students refer to as ‘student success’ based on their own lived experiences and perceptions. It also aims at presenting a proposal towards developing an integrated model for learner support whose objective is to identify students' academic and career needs at the point of entry; refer them to appropriate learning and career development programmes; and thereafter enrol them in a job readiness training and placement programme (JRTP) in preparation for work-integrated learning (WIL) placements.   A mixed methods study was conducted, involving a diagnostic academic literacies assessment, student questionnaires as well as focus group discussions. Participants were the KwaZulu-Natal (KZN)-based Unisa students who had been placed in WIL programmes with and/or without the career development and JRTP experience, and those that had been placed in other jobs not directly related to their qualifications and/or career needs through the JRTP programme.   It was found that most senior students view student success as obtaining a qualification, and being able to use such qualification in gainful employment, whereas junior students placed most emphasis on obtaining a qualification. It was also found that most of the JRTP students perceived the programme as having been helpful in them landing and retaining jobs.
Improvement of learning outcome in material science through inverted classroom techniques and alternative course assessment
Authors: Pfennig Anja
Published: June 2017

Material Science is known to first year mechanical engineering students as one of the fundamental courses with high work load. The knowledge of the complex science of materials enables students to select appropriate engineering materials in different designs due to acquired knowledge on the correlation of materials properties, microstructure and their intended manipulation. These abilities are not well constituted in one final exam. Therefore peer-to-peer lecture film supported inverted classroom szenarios were estabilished to work in the course. These were accompanied by a newly developed moodle course following the blended learning approach that gives students the chance to cumulative accomplish micro-grades via multiple activities, such as tests, lectures, presentations, forum discussions, written homeworks and glossary entries. These grades are summed to obtain the overall course grade. Improved learing outcomes are demonstrated in high quality class discussions and most -important to students- in better grades (average 43/60=B) compared to those being assessed by one final exam only (average 39/69=C+). The majority of students agreed on enhanced study skills when forced to study throughout the entire semester instead of learing intensely towards the end of the semester. This paper introduces the learning structure as well as graded activities, evaluates the course and compares activity results to former class results.
Satisfaction and Getting a Career Employment Expectations of Undergraduate Students and their use of Support Services
Authors: James MacEachern Melissa
Published: June 2017

The purpose of this paper is to explore the factors that affect higher education student satisfaction and future employment and their use of career and other support services while attending an institution.  The descriptive results of this study suggest that while student satisfaction may be relatively similar for all academic programs, students utilize career and other support services very little.  Most notably, the results also indicate students’ expectations for employment was not related to their experience issuing these services. On the contrary, they were mostly satisfied with their academic and personal development. In essence, students felt prepared for the workplace based on their academic experiences rather than through other supports offered by the institution. This paper suggests that institutions efforts are best placed on the academic and learning experience available to their students versus career and support services.
Testing the Trust Game with undergraduates: An experiment with wealth heterogeneity
Authors: Rodrigo-González Amalia , Caballer-Tarazona Maria , García-Gallego Aurora
Published: June 2017

Trust, reciprocity and a fair distribution of resources are cruzial in the sustainabhility of any economic system. As a matter of fact, those are values that should be promoted among the new generations, especially among university students enroled indegrees tha are related to economics.Under this context, we are interested in enhancing criticism and active reflectionamong undergraduates with respect to social values. With  such a goal in mind, we design a two step classroom task that includes playing the Trust Game (TG) in the first place and, second, a discussion activity.This paper is an ext5ension of Caballer-Tarazona et al. (2016) with a novelty: A new treatment is introduced in which subjects have information about the cumulated wealth of their partners.As a complement of the educational propose of the task, data collected during the experiment has been used to test the three hypotheses on trust and reciprocity among students.Two main result emerge: First, information has no effect on trust and reciprocity decisions. And second, in median, a gender effect in such decision is found.

New pedagogical configurations for traditional learning tools: a proposal
Authors: Raimúndez-Urrutia Elena , Azzato Sordo Mariella
Published: June 2017

Digital technologies have changed the world dramatically and, as a consequence, higher education is undergoing significant teaching and learning transformations based on their use. The need to plan and produce disruptive innovations for traditional learning tools brings a challenge in this sense. One of these modern pedagogical perspectives is the use of transmedia storytelling in education, which has given a new configuration to instructional tools and have changed their forms and educational function. We present a proposal of specialized vocabulary in reproductive biology of plants using the principles of transmedia storytelling. The design of an educational transmedia artifact for the particular terminological entry of the term «polinizador» is shown to illustrate the proposed structure for the vocabulary. This artifact is constituted by diverse resources made with the use of different media and is based on the use of tags linked to each resource, which allow interactive navigation between them, structuring the storytelling about the selected term. Each resource adds particular information on the definition of the term, so that the student can obtain the answer he needs. Transmedia storytelling allows the students’ interaction with resources in a way consistent with their own interests, making them the center of their learning.

Innovative Learning Analytics Research at a data-driven HEI
Authors: Azcona David , Corrigan Owen , Scanlon Philip , Smeaton Alan F
Published: June 2017

A university campus is comprised of Schools and Faculties attended by students whose primary intention is to learn and ultimately graduate with their desired qualification.  From the moment students apply to a university and thereafter gain acceptance and attend the campus they create a unique digital footprint of themselves within the university IT systems. Students’ digital footprints are a source of data that is of interest to groups including teachers, analysts, administrators and policy makers in the education, sociology, and pedagogy domains. Learning analytics can offer tools to mine such data producing actionable knowledge for purposes of improving student retention, curriculum enhancement, student progress and feedback, and administrative evolution.  In this paper, we summarise three ongoing Learning Analytics projects from an Irish university, demonstrating the potential that exists to enhance Higher Education pedagogical approaches.   First year students often struggle with making the transition into University as they adapt to life and study at a Higher Education Institution. The research projects in the area of Learning Analytics at our institution focus on: improving test performance using analytics from a general-purpose VLE like Moodle, identifying studying groups and the performance peer effect using on-campus geolocation data, and detecting lower-performing or at-risk students on programming modules.
Researcher, PI and CEO - Managing a Large Scale Environmental Restoration Project in New York City; Creating Expectations, Establishing Structure, Protocols and Realistic Outcomes
Authors: Birney Lauren Beth , Diamantakos George
Published: June 2017

Abstract Research consistently shows that children who have opportunities to actively investigate natural settings and engage in problem-based learning greatly benefit from the experiences? This project developed a model of curriculum and community enterprise to address that issue within the nation's largest urban school system. Middle school students will study New York Harbor and the extensive watershed that empties into it, as they conducted field research in support of restoring native oyster habitats. The project builds on the existing Billion Oyster Project, and was implemented by a broad partnership of institutions and community resources, including Pace University, the New York City Department of Education, the Columbia University Lamont-Doherty Earth Observatory, the New York Academy of Sciences, the New York Harbor Foundation, the New York Aquarium, and others. The project model includes five interrelated components: A teacher education curriculum, a digital platform for project resources, museum exhibits, and an afterschool STEM mentoring program. It targets middle-school students in low-income neighborhoods with high populations of English language learners and students from groups underrepresented in STEM fields and education pathways. This paper explores the management of this large-scale project and provides insight with regard to the governance of the various project components.   Key words (project-based learning, environmental restoration, educational technology)
Developing Communication Competencies Through E-Learning: The Motivating Potential of Adaptive Video Role Play
Authors: Hiemstra Djoerd , Zagt Anne Carine
Published: June 2017

Abstract To develop competence through e-learning tools, students must be motivated to use these tools. Hence, we conducted two empirical studies to explore the motivating potential of an adaptive video role playing game (AVR) for training communication competencies. In Study 1 (N = 54), we used a within-person design to examine students’ motivation in three learning conditions: in the classroom, when playing the AVR, and when doing homework. The results showed that, relative to the homework condition, in the AVR condition students were higher in perceived competence, relatedness, intrinsic motivation, and flow. No difference between the classroom condition and the AVR condition were found. In Study 2 (N = 150), we used a randomized experimental design to examine the motivational consequences of using videos (AVR) rather than photos (APR) in the adaptive role playing game. We found that, relative to students in the APR condition, students in the AVR condition were higher in relatedness and flow. No differences in perceived competence, autonomy, and intrinsic motivation were observed. We conclude that an AVR may have considerable motivational benefits relative to common homework assignments, and some motivational benefits relative to an APR. Keywords: e-learning, video role play, games, motivation, flow
What should students learn in the digital world?
Authors: Harth Thilo , Dellmann Frank
Published: June 2017

The rapid changes in the working environment and society as a whole as a result of digitalisation demands a new and changed competence profile. Specialist requirements are changing, and extracurricular requirements are of growing significance. Curriculum development at higher education institutions should take note of this change in order to ensure that higher education graduates are ready for professional life, and to reinforce personal development in the digital world. What should students learn in the digital world? This question invites us to consider further, from a digital perspective, the competency orientation in higher education. This article will demonstrate approaches to competency-oriented curriculum development, to consider the digital transformation in skills profiles and to render this process more dynamic. This article is based on experiences at a higher education institution that has encountered the challenges of digital transformation.
Embedding Information Rights into Higher Education in the UK
Authors: Adshead Deborah Alison
Published: June 2017

Estimates suggest that a data breach costs an organisation over $4 million and that the total global cost of breaches will soon exceed $2 trillion. Hacking is part of the problem but errors in processing by individuals are still the most reported reasons for data breaches in the UK. With predictions of more jobs involving data processing in the future and the exponential growth in accessible personal data, it is increasingly important that this problem is taken more seriously. This Information Commissioner’s Office (ICO) sponsored research constitutes stage one of a study into the teaching of Information Rights (IR) in HE across the UK including depth interviews with professional bodies and Pro Vice-Chancellors, and an online survey aimed at Heads of Departments. Though not widespread, the research found instances of IR being taught but some barriers to embedding it across relevant subjects do exist, including: • tutor expertise; • development and consistency of materials; and • competing curriculum development drivers. Most respondents recognised the increasing importance of IR and welcomed ICO support with this but also felt that despite the proposal of accreditation as a motivator to improve the situation buy-in would be more likely if it was part of overall management strategy.
Teaching Theory in Applied Degrees: A Critical Examination of Curricular Design for Translation Theory Subjects in Comparison with the Students' Expectations
Authors: Ordóñez López Pilar , Agost Rosa
Published: June 2017

Due to the practice-oriented nature of Translation and Interpreting study programmes, students are generally assumed to have a reluctant attitude towards the study of theory. However, previous empirical research allows us to dispel this myth: students are aware of the contribution of translation theory to their education as future translators. Taking into account students' needs and expectations, in this paper emphasis is placed on curricular design. A critical examination of the syllabi of Translation Theory subjects, focusing on learning outcomes and teaching methodology, reveals some (mis)matches between teaching planning and the students' expectations. The results obtained show a relatively high degree of coincidence between these two aspects on the one hand, while also highlighting some inaccuracies in the teaching planning of these subjects on the other. These two aspects should be considered a starting point for a revision of the curricular design in order to present an accurate description of the subject by means of an adequate explanation of the intended learning outcomes and teaching methodology, and in order to provide students with significant and useful insights into the theoretical dimension of translation.
Gamification in teaching Maintenance Engineering: a Dutch experience in the rolling stock management learning
Authors: Martinetti Alberto , Parada Puig Jorge Eduardo , Oude Alink Charlotte , Thalen Jos , Van Dongen Leo A.M.
Published: June 2017

The aim of this study is to evaluate the application of an innovative serious game based on the asset management of rolling stock in the training of future maintenance engineers within the master course in mechanical engineering at the University of Twente. The Logistic Support Game (LSG) is a serious game developed together with Dutch Railway (Nederlandse Spoorwegen, NS) and Invocate (design firm) as a tool to simulate the maintenance operations of a fleet of trains. The simulation shows four perspectives: the operations manager, the asset manager, the maintenance manager and the financial manager. The three goals of this innovative training are the improvement of student engagement in the learning process, the increasing of active cooperation between students with different roles in a group, and the opportunity to receive feedback on decision making. To indicate achievement of these goals we link them to the basic needs of learning: competence, relatedness and autonomy. A total of thirty six students played the serious game in two different sessions. At the end of each session, a survey is collected for game based learning assessment. Results suggest that the serious game has a positive impact on student engagement, cooperation, and helps transfer course contents.
Project Based Learning experience with engineering students for the design of steel structures
Authors: Ibáñez Usach Carmen , Hernández Figueirido David
Published: June 2017

This work describes the Project Based Learning (PBL) experience carried out with engineering students in the field of steel structures design during the academic year 2016-2017 at the Universitat Jaume I of Castellón de la Plana (Spain). This experience is integrated in the Master of Science in Industrial Engineering. The experience consists of simulating the activity of a technical office dedicated to the development of structural projects. A real situation comprising the design and calculation of an industrial building for a costumer is presented to the students. Some geometrical aspects according to the customer desires and the industrial process to be set at the building are specified. The students are organized in groups and have to work in a project to develop a competitive solution to this real necessity within deadline. Finally, a survey is conducted to evaluate both the impact of this experience in the learning process and the students’ degree of satisfaction with respect to this technique. The results of the survey show that PBL promotes the technical training of the students in this field and encourages the development of transversal skills, enhancing, at the same time, their motivation.
Student Evaluation of Teaching (SET): Clues on how to interpret written feedback
Authors: Schiltz Guillaume
Published: June 2017

In this paper we present the preliminary results of a study covering 217 written comments submitted in the formal university SET questionnaire of two undergraduate physics lectures for engineering students. Concerning the SET-metrics, one of the lectures was rated as critical, while the other lecture had good results. The analysis is based on the praise and criticism framework elaborated by Hyland/Hyland (2001) for written feedback. Our findings, which also relate written feedback to quantitative variables and contrast the results between critical and good evaluations, provide a deeper insight for both, teachers and educational developers, on how to interpret written comments in a quality management process.
Students’ surveys and involvement in educational activities within virtual environments are related to students’ satisfaction in e-learning graduate programs
Authors: Barrós-Loscertales Alfonso , Marquez-Ramos Laura , Climent Oscar , Bueichekú Elisenda , Bustamante Juan Carlos
Published: June 2017

This paper evaluates associations across the dimensions included in students’ surveys and virtual activities for applying educational models within e-learning graduate programs. Firstly, we focus on the outcomes derived from teachers’ and students’ participation in virtual classroom forums and, secondly, on the determinants of students’ satisfaction in the graduate program. Data analyses show that teachers’ and students’ participation in forums as dynamic educational activities are positively correlated with students’ general satisfaction. To study the determinants of students’ satisfaction, we perform a regression analysis that considers as explanatory variables educational planning, teaching qualifications and development of learning, as well as of a number of controls related to the virtual learning environment and participation in the academic program. According to the obtained results, teaching skills and learning environments are associated with higher students’ satisfaction in a virtual learning environment. This type of analysis is of great interest in a social environment characterized by increasing communication via electronic networking. We find that dynamic educational activities and dimensions taken on board on students’ surveys are related to students’ satisfaction in e-learning graduate programs.
Boosting the Employability of Students and Staff at European Higher Education Institutions: An Educational Framework for Entrepreneurship, Internationalisation and Innovation
Authors: Saulich Christina , Lehmann Tine
Published: June 2017

Globalisation has altered the conditions of work and learning in Europe. Many European countries specialise in non-offshorable, knowledge- and skill-intensive tasks which require a highly educated workforce that is able to interact in global settings. European Higher Education Institutions (HEI) face the challenge of meeting the increased demand for skills of globalised work environments. In order to do this, HEI need to adapt their educational concepts. This involves promoting internationalisation, entrepreneurial and innovation skills. This paper aims to develop an educational framework for boosting student and staff employability at European HEI. It further adds to the practical dimension of HEI internationalisation, entrepreneurship education and innovation pedagogy by presenting an example how these interrelated concepts can be integrated into the curricula of HEI. At the methodological level this implies broadening traditional content-focused curricula and making use of active teaching methods that foster deep learning, best acquired in real work situations. Taking internationalisation serious further entails building up virtual learning networks and tapping the full potential of e-learning.
Objective versus subjective methods to assess discipline-specific knowledge: a case for Extended Matching Questions (EMQs)
Authors: Slattery Robyn Maree
Published: June 2017

Background: Extended matching questions (EMQs) were introduced as an objective assessment tool into third year immunology undergraduate units at Monash University, Australia. Aim: The performance of students examined objectively by multiple choice questions (MCQs) was compared to their performance assessed by EMQs; there was a high correlation coefficient between the two methods. EMQs were then introduced and the correlation of student performance between related units was measured as a function of percentage objective assessment.  The correlation of student performance between units increased proportionally with objective assessment.  Student performance in tasks assessed objectively and subjectively was then compared. The findings indicate marker bias contributes to the poor correlation between marks awarded objectively and subjectively. Conclusion: EMQs are a valid method to objectively assess students and their increased inclusion in the assessment process increases the consistency of student marks.  The subjective assessment of science communication skills introduces marker bias, indicating a need to identify, validate and implement, more objective methods for their assessment. Keywords: Extended matching question (EMQ); Objective assessment (OA); SA (SA);  Marker bias; Discipline-specific assessment; Science communication assessment
An Interdisciplinary 4th Level Education Model:Connected Health
Authors: Mountford Nicola , Watts Gemma , Fernandez Luque Luis , Chouvarda Ioanna , Kessie Threase , Cusack Tara
Published: June 2017

This paper responds to the need for interdisciplinary approaches to fourth level education that better reflect the complexity of the world in which we work and conduct research. We discuss this need in technology-enabled healthcare, Connected Health. We propose a model for fourth level interdisciplinary education and discuss its trial application in two European structured PhD programmes in the Connected Health research arena. We suggest broader learning objectives for the emerging fourth level graduate, methods for incorporating multiple disciplinary inputs and perspectives into deep disciplinary PhD training, intersectoral approaches to ensure employability and impact, and innovative training methods and structures to facilitate interdisciplinary and intersectoral learning. We give some examples of innovative training modules used within the pilot programmes. Finally we discuss six core elements of a truly interdisciplinary programme at fourth level - exposure to different environments, joint supervision, a genuine role for the non academic sector, career development training and planning, the development of a sustainable network beyond the life of the programme, and data openess.
“Walking a tight rope”- a risky narrative of transition to University
Authors: Prevett Pauline Suzanne
Published: June 2017

The study of the transition of young people to university necessarily confronts the semi-dependency of the lives of contemporary youth: on the one hand they remain largely economically dependent and on the other they are becoming socially independent.  We therefore seek to illuminate engagement with learning as situated in the midst of semi-dependency typical of adolescence, at a time in the life-cycle when typically young people experience a strong “pull” to socialise with peers, but have not yet become fully economically and socially adult. The paper examines the consequences of this contradiction on students’ transition to university, from the subjective experience of students as they transition to university. We suggest disengagement and even drop out from studies can arise from a contradiction between the students’ social and study (economic) domains. The dependency is not only economic, but is culturally mediated and may therefore be experienced by some students in more acute forms. Cultural aspirations and family expectations and ties can provide the impetus to succeed and so overcome the emotional challenges encountered, and these ties may help them walk a tight rope to success. Finally, we explore the consequences for policy and practice.
Animal welfare and Ethics course for post-graduate at Veterinary School: how to improve assessment methodologies with a bottom up approach
Authors: Ferrante Linda , Normando Simona , Florio Daniela , De Mori Barbara
Published: June 2017

Animal Welfare, with its strong ethical component, is increasingly central to public debate and in all sectors dealing with animals has become a key expertise to acquire. This paper presents a post-graduate level course on animal welfare and ethics assessment delivered by the Veterinary School of Padua University, Italy. The course was delivered at Garda Zoological Park, Italy, allowing students to do an experience with wildlife in a peculiar management system. Teachers used an inquiry-based approach to lead students ‘construct’ their experience in welfare assessment. At the end of the course students, divided into groups, had to develop a protocol for the assessment of the animal welfare of a species in the zoo. The analysis of these final works and a pre-test and post-test questionnaires were used to assess the effectiveness of the course. Results highlighted a growing awareness of the complexity of assessment methodologies and more attention on animal based indicators. Students found difficulties using a bottom-up approach but were satisfied at the end of the course. Improvements can be done to promote reflections on reasons to assess animal welfare and its ethical component, on the utility of such assessment and on a balanced use of tools and methodologies.
O ensino da dança e a relação de gênero na educação básica

Published: June 2017

A presente pesquisa objetivou o estudo do ensino da dança no ambiente escolar e a relação de gênero entre os alunos, no ensino de Educação Física. Foi desenvolvida por meio de uma pesquisa transversal de coleta única de dados, de análise exploratória, utilizando dois questionários, um com 03 professores, e outro com 24 alunos, com questões fechadas e abertas. Os dados coletados foram analisados por meio do programa estatístico SPSS 22.0. Verificou-se que 66,7% dos professores afirmaram trabalhar com a dança direcionada às festividades escolares e 100%, de forma recreativa, 66,7% a aplicam para o desenvolvimento de aspectos motores, cognitivos, perceptivos e socioafetivos, o que não foi confirmado pelos alunos. Concluiu-se que a dança não está sendo utilizada nas aulas de Educação Física devido a motivos, como: a falta de qualificação dos professores, ausência de espaço adequado e materiais de apoio, ideias sexistas diferenciando a prática e os preconceitos existentes entre os alunos, relacionados a gênero.
Characterization of organic nitrate constituents of
secondary organic aerosol (SOA) from nitrate-radical-initiated
oxidation of limonene using High-Resolution Chemical Ionization Mass Spectrometry
Authors: Faxon Cameron , Hammes Julia , Pathak Ravi Kant , Hallquist Mattias
Published: June 2017

Abstract. The gas phase nitrate radical (NO3•) initiated oxidation of limonene can produce organic nitrate species with varying physical properties. Low-volatility products can contribute to secondary organic aerosol (SOA) formation and organic nitrates may serve as a NOx reservoir, which could be especially important in regions with high biogenic emissions. This work presents the measurement results from flow reactor studies on the reaction of NO3• and limonene using a High-Resolution Time-of-Flight Chemical Ionization Mass Spectrometer (HR-ToF-CIMS) combined with a Filter Inlet for Gases and AEROsols (FIGAERO). Major condensed-phase species were identified, and the identity and volatility properties of the most prevalent organic nitrates in the produced SOA were determined. Analysis of multiple experiments resulted in the identification of several dominant species (including C10H15NO6, C10H17NO6, C8H11NO6, C10H17NO7, and C9H13NO7) that occurred in the SOA under all conditions considered. The observed and expected (listed) products (associated with the Master Chemical Mechanism (MCM) limonene mechanism) were compared, and many non-listed species were identified. Additionally, the formation of dimers was consistently observed and these species resided almost completely in the particle phase. The identities of these species are discussed, and formation mechanisms are proposed. Cluster analysis of the desorption temperatures corresponding to the analyzed particle-phase species yielded at least five distinct groupings based on a combination of molecular weight and desorption profile. Overall, the results indicate that the oxidation of limonene by NO3• produces a complex mixture of highly oxygenated monomer and dimer products that contribute to SOA formation.
Calcium carbonates: Induced biomineralization vs. controlled macromorphology?
Authors: Meier Aileen , Kastner Anne , Harries Dennis , Wierzbicka-Wieczorek Maria , Majzlan Juraj , Büchel Georg , Kothe Erika
Published: June 2017

Abstract. Biomineralization of (magnesium) calcite and vaterite by bacterial isolates has been known for quite some time. However, the extracellular precipitation hardly has been linked to different macro-mophologies of the minerals that are observed. Here, isolates from limestone associated groundwater, rock and soil were shown to form calcite; magnesium calcite or vaterite was also present. More than 92 % of isolates indeed could form carbonates, while aboitic controls failed in mineral formation. The crystal morphologies varied, including rhombohedra, prisms and pyramid-like macro-morphologies. Using different conditions like varying temperature, pH or media components, but also co-cultivation to test for collaborative effects of sympatriotic bacteria, were used to differentiate mechanisms of calcium carbonates formation. Single crystallites were cemented with bacterial cells; these may have served as nucleation sites by providing a basic pH at short distance from the cells. A calculation of potential calcite formation of up to 2 g per liter of solution could link the microbial activity to geological processes.
ShellTrace v1.0 – A new approach for modelling growth and trace element uptake in marine bivalve shells: Model verification on pacific oyster shells (Crassostrea gigas)
Authors: de Winter Niels J.
Published: June 2017

Abstract. Bivalve shells record changes in their environment in the chemical composition of their shells and are frequently used as paleoclimate archives. However, many studies have shown that physiological changes related to growth of the bivalve may overprint these chemical tracers. In the present study, a new approach is presented that models growth and development of bivalve shells without a priori knowledge of the physiology of the species. The model uses digitized growth increments in a cross section of the shell together with basic assumptions of the shape of the shell in order to model changes in shell length, thickness, volume, mass and growth rate at a daily resolution through the lifetime of the bivalve. This approach reconstructs the growth history of bivalves based on their shell without the need for a culture experiment, paving the way for growth rate estimations based on fossil bivalve shells. Combination of the growth model with 2D X-Ray Fluorescence trace element mapping allows the incorporation of trace elements into the shell to be modelled in 3D through the bivalve's lifetime. This approach yields records of integrated total-shell trace element concentrations and accumulation rates, which shed light on the rates and mechanisms by which these trace elements are incorporated into the shells of bivalves. Application of growth and trace element modelling on a set of modern pacific oyster shells of well-known origin and comparison of model results with conventional trace element transects highlights the importance of considering heterogeneity in mineralogy, mineralization rates and chemical composition within the shells of bivalves. These insights lead to a better understanding of the complexity of trace element concentrations in bivalve shells, which can then be applied as proxies for the reconstruction of sub-annual changes in palaeoenvironmental conditions over geological timescales.
Seeing the Growth: Strengthening Teacher Connectedness Through Outward Bound Excursions
Authors: Turke Shani Rose , Caldas Stephanie V. , Kågesten Anna , Parsons Jennifer , Ahn Ji Young , Winch Peter
Published: June 2017

Positive teacher-student relationships are protective for various health outcomes in adolescence. Evidence suggests that outdoor education programs, such as Outward Bound (OB), have the potential to encourage social skill development, but little research has investigated programs’ effects on teacher-student relationships. This study assessed high-school teacher connectedness following participation in OB excursions. Twelve in-depth interviews with teachers and two focus groups with OB instructors were conducted in the Chesapeake Bay area. Data were analyzed in Atlas.ti using an iterative, Grounded Theory methodology. As OB trips altered the role teachers often played in their classrooms, informants perceived increased trust with participating students as they developed shared memories. The effects of OB extend beyond individual-level outcomes to encourage positive relationships between high-school teachers and their students. Given these findings, educators may want to consider incorporating outdoor education programs into their curricula as a way to engage teachers and students beyond their prescribed roles in the classroom.
El origen de los primeros principios según Tomás de Aquino. Una dificultad interpretativa
Authors: Valdivia Fuenzalida José Antonio
Published: June 2017

En el libro I de su Comentario a los Analíticos Posteriores, Tomás de Aquino explica que toda demostración supone la existencia de principios evidentes e indemostrables que aseguren la certeza de las conclusiones. Para garantizar la existencia de verdades ciertas e indemostrables, introduce la idea de las proposiciones per se notae. Estas proposiciones son típicamente caracterizadas por tener un predicado que forma parte del contenido inteligible del sujeto, es decir, por ser proposiciones analíticas. Ahora bien, al final del libro II, cuando explica cómo se obtienen los principios de las demostraciones, la doctrina expuesta no parece ser perfectamente congruente con la de las proposiciones per se notae, por describir un proceso inductivo más apto para explicar el surgimiento de proposiciones no analíticas. El objetivo del este artículo es proponer una solución de este problema, distinguiendo entre dos tipos de principio. La pertinencia de tal distinción se intentará demostrar comentando algunos textos de Roberto Grosseteste y Alberto Magno.
¿Hay nada antes del principio? Acerca del sentido y de la sostenibilidad de la idea de creatio ex nihilo en La Estrella de la Redención de F. Rosenzweig
Authors: Garrrido-Maturano Ángel Enrique
Published: June 2017

El estudio analiza desde una perspectiva fenomenológica la idea de creación en La Estrella de la Redención de Franz Rosenzweig. El análisis determina primero en qué medida el concepto de creación puede ser considerado bajo la categoría de creatio ex nihilo y qué concretamente ha de entenderse por tal. Luego explicita hasta qué punto es legítimamente sostenible la concepción de la creación desde la nada postulada por Rosenzweig y cuál es su estatus epistemológico confrontada con un estudio científico del problema. Finalmente elucida cómo creatio ex nihilo y creatio continua se implican y presuponen mutuamente en el pensamiento rosenzweiguiano.
Dios y el coito: entre la misoginia y el feminismo
Authors: Calabuig Cañestro Noemí
Published: June 2017

El objetivo de este trabajo es señalar que para la reflexión filosófica sobre los sexos hay dos cuestiones de vital importancia que están íntimamente relacionadas: el significado que atribuimos al coito y cómo entendemos la relación del ser humano con lo absoluto (o con Dios). Para ello, recurriremos a las filosofías de dos autores que representan opciones antagónicas en esta materia: Otto Weinigner, un autor indudablemente misógino, y Simone de Beauvoir, precursora del feminismo. Dado que sus discursos coinciden en muchos aspectos relevantes —pues ambos identifican los valores masculinos con los valores humanos, creen que las mujeres han sido víctimas de un engaño y defienden la desaparición de la feminidad—, la razón por la que merecen juicios contrapuestos debe de hallarse en sus discrepancias. Aquí defendemos que la divergencia fundamental entre sus teorías está en el significado que atribuyen al coito y que este depende del tipo de relación que proponen entre el ser humano y la divinidad. La comparación entre estos autores revela el carácter fundamental de dichas cuestiones para el discurso filosófico sobre los sexos.

Authors: Marín Garcia Jorge Luiz
Published: June 2017

El wixarika - más conocido como huichol - existe en el imaginario teiwari (no wixarika) de distintas maneras. Pero dichaimágenes no emergen de la naturaleza o dictadas por una mano omnipotente que asignó a cada quien prácticas culturalesespecíficas, como suele mirarse inconscientemente aún en ámbitos académicos; sino de un contexto histórico culturaldel que ellos y sus “Otros” son actores y producto. En ese sentido, este artículo pretende explicar la transformación de laimagen del wixarika en el imaginario teiwari a través de las problemáticas relaciones que ambas sociedades ha entabladoa lo largo de los siglos. Para ello se toma como eje el arte huichol, poderoso referente actual de la identidad wixarika.
