This article is derived from the research project and developed at School of Computer Sciences of the National Polytechnic Institute of Mexico. The article reports on the problems found among engineering students with respect to their resistance to using different representation registers when solving optimization problems in the Calculus Learning Unit. Use of such registers could help the students to build mathematics knowledge and to solve calculus problems. As a didactic strategy, simulations are used in an electronic environment in order to support the students by fostering their use of tabular, graphical and algebraic representation registers. Interviews are undertaken of six of the professors who gave the calculus courses, and a diagnostic questionnaire was applied to 68 students prior to and after working with the proposal. As for the theoretical framework, the work reported by Duval and Hitt is salient in this report, particularly their emphasis of the fact that working on activities by way of one single representation system is not sufficient. From the first responses provided by the students, one can conclude that the algebraic register is preferred by the majority of students. It is however used in a mechanical fashion without affording any meaning to the content of the problem and to the process of solving it. Another conclusion reported is that implementing tasks in the classroom in which the mathematics activity requires coherent use of different representations is necessary

Preliminary Study

The music that children are exposed to in their everyday lives plays an important role in shaping the way they interpret the world around them, and television soundtracks are, together with their direct experience of reality, one of the most significant sources of such input. This work is part of a broader research project that looks at what kind of music children listen to in a sample of Latin American and Spanish TV programmes. More specifically, this study focuses on children’s programmes in Spain, and was addressed using a semiotic theoretical framework with a quantitative and musical approach. The programme «Los Lunnis» was chosen as the subject of a preliminary study, which consisted in applying 90 templates and then analysing them in terms of the musical content. The results show that the programme uses music both as the leading figure and as a background element. The most common texture is the accompanied monody and the use of voice, and there is a predominance of electronic instrumental sounds, binary stress and major modes with modulations. Musical pieces are sometimes truncated and rhythmically the music is quite poor; the style used is predominantly that of foreign popular music, with a few allusions to the classical style and to incidental music. The data reveal the presence of music in cultural and patrimonial aspects, as well as in cognitive construction, which were not taken into account in studies on the influence of TV in Spain. Such aspects do emerge, however, when they are reviewed from the perspective of semiotics, musical representation, formal analysis and restructuring theories.La música de la vida cotidiana del niño tiene uno de sus referentes, junto a su experiencia real, en la banda sonora de la televisión, configurando una parte de su interpretación de la realidad. Este trabajo forma parte de una investigación más amplia sobre la escucha televisiva infantil en una muestra iberoamericana. El objetivo, conocer qué escuchan los niños en la programación infantil de «Televisión Española», ha sido estudiado desde un marco teórico semiótico con un enfoque cuantitativo y musical. El artículo presenta un resumen de los resultados obtenidos en un primer análisis del programa «Los Lunnis» mediante la aplicación de noventa plantillas y sus análisis musicales correspondientes. Estos resultados indican que el programa utiliza la música como fondo y figura, textura de monodía acompañada y utilización de la voz, predominio del sonido electrónico instrumental, acento binario y modo mayor con modulaciones. Aparecen piezas musicales cortadas y cierta pobreza rítmica, su opción estilística es la música popular no propia, con algunos guiños al estilo clásico y a la música incidental. Los datos muestran la presencia de la música en aspectos culturales, patrimoniales y de construcción cognitiva no considerados en los estudios sobre la influencia de la TV en España, pero que emergen cuando son revisados desde la semiótica, la representación musical, el análisis formal y las teorías de la reestructuración.

Organizational Safety Culture

In the frame of an on-going 4-years research project, the Aviation Academy Safety Culture Prerequisites (AVAC-SCP) metric was developed to assess whether an organisation plans and implements activities that correspond to prerequisites for fostering a positive safety culture. The metric was designed based on an inclusive theoretical framework stemmed from academic and professional literature and in cooperation with knowledge experts and aviation companies. The goal of the AVAC-SCP is to evaluate three aspects, namely (1) the extent to which the prerequisites are designed/documented, (2) the degree of the prerequisites’ implementation, and (3) the perceptions of the employees regarding the organizational safety culture as a proxy for the effectiveness of the prerequisites’ implementation. The prerequisites have been grouped into six categories (common prerequisites and just, flexible, reporting, information and learning cultures) and the metric concludes with scores per aspect and category. The results from surveys at 16 aviation companies showed that these companies had adequately included most of the Safety Culture Prerequisites (SCP) in their documentation where Just culture plans scored the lowest and Reporting culture plans were found with the highest percentage of planning. The level of SCP implementation was the same high as the organisational plans and quite uniform across the companies and sub-cultures. The perceptions were at the same overall level with implementation, but employees perceived the organisational environment as less fair and more flexible than managers claimed. Although the study described in this report was exploratory and not explanatory, we believe that the results presented in combination with the ones communicated to the participating companies can trigger the latter to investigate further their weaker areas and foster their activities related to Safety Culture Prerequisites. Also, the AVAC-SCP metric is deemed useful to organisations that want to self-assess their SCP levels and proceed to comparisons amongst various functions and levels and/or over time.

Purpose The purpose of this paper is to report on untold stories that not only illustrate the creativity but also complexity of working in outdoor events. There has been global interest in the creative industries and the creative economy more generally. Events have not been identified or categorised as part of this. Experiences have been identified as part of the creative sectors (NESTA, 2006) and events are seen as experiences (Jackson, 2006; Berridge 2007). There has been little research undertaken about the creative nature of event experiences, especially in how they are created. Design/methodology/approach A theoretical framework was created from literature on creativity more generally to inform the Creativity in Events research project. Interviews with those working in the outdoor events sector were the basis of the qualitative stage of the research project investigating the phenomenon of creativity in events. Findings This paper identifies the core facets of creativity in the management of outdoor events. These were fluency, originality, imagination, elaboration, environment and complexity. A vignette is used to illustrate the intricacy of the nature of creativity in the production of outdoor event experiences. The overall findings were that event management was both creative and pragmatic and that both are necessary. There was a need for a creative environment with processes and familiarity that aided inspiration and originality. Originality/value The background and findings are relevant to recognising events as part of the wider creative economy. A greater understanding of the nature of creativity in events informs both education and practice.

The existing gap of mathematics knowledge was identified as the major contributor to the decline in the students’ performance on the Integral Calculus at the university level. This phenomenon has led to university students’ difficulties in identifying the correct integration techniques and developing understanding on applications of the Integral Calculus. This study aims to analyse the effectiveness of e-INTEGRAL MAP in the learning of Integral Calculus among engineering students of advanced Calculus class. A total of 118 diploma engineering students were involved in an experimental design research to study on the usage and effectiveness of e-INTEGRAL MAP. Study was performed on 65 students in control group and 53 students in treatment group, using the pre-test and post-test experimental design methodology where the effectiveness of the maps was measured through their performance scores. Findings indicate that both control and treatment groups showed significant differences in post-test scores during the two months study. The majority of e-INTEGRAL MAP users found the maps very useful, helpful, easy to understand and user-friendly because it was systematically designed. In conclusion, e-INTEGRAL MAP significantly improved the students’ performance and understanding on the topic of Integral Calculus as compared to the conventional text-book learning.

This work aims to show how commensality, a dimension of hospitality, operates in the context of new Internet businesses. It uses theories of hospitality to analyse meal-sharing websites that seek to capitalize on the booming interest in gastronomy and the growing trend of the sharing economy. This article is one piece of a broader research project that aims to identify and characterize the protagonists of a new type of gastronomy and commensality business conducted in domestic environments, and promoted on meal-sharing websites in which professional or amateur chefs (hosts) and diners (guests) are connected with one another. To perform the study we conducted documentary research through Internet searches on shared gastronomic experiences; netnographic research on meal-sharing websites; and interviews with hosts registered on these platforms and with the owner of the Brazilian website Dinneer. Using a theoretical framework focusing on hospitality and commensality, which deals with the relations between hosts and guests, their motivations and wishes, and the tacit and explicit rules by which they are bound, we analysed the contents of the websites and the interview transcripts. The results of our research reveal a paradox about the services offered on the websites and the reality of the business for hosts and diners.

In engineering studies, students need specific English language practices to communicate effectively in professional settings. This research project was carried out for two main purposes. First, the aim was to evaluate to what extent the English for general purposes courses offered to engineering students at the National School of Applied Sciences of Fes were successful in fulfilling the job requirements of the prospective engineers. And the second purpose was to devise an ESP (English for specific purposes) course that is rather linked to the field of specialization of the respondents and can attend to their vocational needs. To this end, a “needs analysis questionnaire” was devised to identify these students’ needs in relation to the English language course. The results stressed the significance of English for engineering students. They also identified the students’ lacks, needs and interests regarding English language. The study concluded with some pedagogical implications.

Taking social movement theory as my theoretical framework, this paper examines the ways in which the practices and services of Toronto organizations such as the Stop Community Food Centre, FoodShare, and Not Far From The Tree promote countercultural food ideologies and thus may be viewed as actors attempting to influence political and social change through food. While individual organizations should not be confused with social movements, it is possible that we may be able look at this ensemble of organizations as an informal network that exemplifies a new contemporary form of social movement."--Pages 3-4.

Abstract Hochschule Wismar, Germany, has been implementing Master programmes for international students since 1992. However, for most European universities, it is a rather new phenomenon. The purpose of the work is to analyse scientific literature on European higher education programmes for international students and to outline a theoretical framework of European higher education programmes for international students underpinning elaboration of new research question on master programmes for international engineering students. The research methodology comprises the study of the meaning of the key concepts of “framework”, “theoretical framework” and “international students”. Moreover, the logical chain of analysis is shown: theoretical framework → empirical study within a multicultural environment → conclusions. The case study research is applied. The empirical study was carried out at Hochschule Wismar, Germany in March 2017. Semi-structured interview served as the basis for data collection. The empirical findings allow complementing the elaborated theoretical framework consisting of the concepts on reasons for, language and impact of Masetr programme for international students with such a concept as European Credit Transfer System (ECTS). Directions of further research are proposed. The novel contribution of the paper is the newly formulated research question on master programmes for international students.
