Contribution à l’étude de la dynamique des espèces végétales envahissantes face aux fluctuations des précipitations et des températures dans la plaine de Sidi Bel Abbes (Algérie)

Le développement des mauvaises herbes dans la plaine de Sidi Bel Abbes (Algérie) constituent un facteur agroécologique déterminant sur la qualité de la récolte et des rendements. L’impact sur les agrosystèmes reste important et est tributaire de deux paramètres climatiques : précipitations et températures. Lutter efficacement contre les mauvaises herbes dans les agrosystèmes exige une connaissance de leur dynamisme. Les mauvaises herbes se développent en relation avec les précipitations et présentent un spectre différent chaque année. Une connaissance des espèces à forte présence constitue une base fondamentale pour diminuer leur présence. Cerner le spectre de développement des principales espèces végétales nuisibles dans les céréales et l’appréciation de leur dynamisme est le but de cette étude. Le développement des mauvaises herbes dans les céréales reste un problème préoccupant et sa prise en charge pour organiser une lutte efficace passe par une compréhension de la dynamique phytoécologique.

Investigación acción participativa y compromiso social del arquitecto: estudio de un caso

Presentamos la Investigación Acción Participativa (IAP) que hemos llevado a cabo en un barrio de las afueras de Albacete, cuyo nombre popular, “las 500”, evidencia su condición marginal (perfil social, patologías constructivas, viviendas mínimas) de polígono de vivienda social promovido por la Obra Sindical del Hogar en los primeros 60. Ha consistido en aprovechar la oportunidad que nos brindaba la inauguración de su nueva iglesia para buscar la documentación y estudiar la arquitectura y el urbanismo del barrio, permitiendo su conocimiento y su valoración para darlo a conocer y a valorar y para irlo mejorando. La acción principal se ha concretado en una exposición itinerante que conmemora su 50 aniversario.

Comparing Common Data Environment Platforms for Student Collaborative Working: A Case Study from Ulster University

PAS1192-2 (2013) outlines the “fundamental principles of Level 2 information modeling”, one of these principles is the use of what is commonly referred to as a Common Data Environment (CDE). A CDE could be described as an internet-enabled cloudhosting platform, accessible to all construction team members to access shared project information. For the construction sector to achieve increased productivity goals, the next generation of industry professionals will need to be educated in a way that provides them with an appreciation of Building Information Modelling (BIM) working methods, at all levels, including an understanding of how data in a CDE should be structured, managed, shared and published. This presents a challenge for educational institutions in terms of providing a CDE that addresses the requirements set out in PAS1192-2, and mirrors organisational and professional working practices without causing confusion due to over complexity. This paper presents the findings of a two-year study undertaken at Ulster University comparing the use of a leading industry CDE platform with one derived from the in-house Virtual Learning Environment (VLE), for the delivery of a student BIM project. The research methodology employed was a qualitative case study analysis, focusing on observations from the academics involved and feedback from students. The results of the study show advantages for both CDE platforms depending on the learning outcomes required.

The Influence of Space Layout, Technology and Teaching Approach on Student Learning: An Architectural Technology Perspective

Some would argue that there is a need for the traditional lecture format to be rethought in favour of a more active approach. However, this must form part of a bipartite strategy, considered in conjunction with the layout of any new space to facilitate alternative learning and teaching methods. With this in mind, this paper begins to examine the impact of the learning environment on the student learning experience, specifically focusing on students studying on the Architectural Technology and Management programme at Ulster University. The aim of this study is two-fold: to increase understanding of the impact of learning space layout, by taking a student centered approach; and to gain an appreciation of how technology can impact upon the learning space. The study forms part of a wider project being undertaken at Ulster University known as the Learning Landscape Transition Project, exploring the relationship between learning, teaching and space layout. Data collection was both qualitative and quantitative, with use of a case study supported by a questionnaire based on attitudinal scaling. A focus group was also used to further analyse the key trends resulting from the questionnaire. The initial results suggest that the learning environment, and the technology within it, can not only play an important part in the overall learning experience of the student, but also assist with preparation for the working environment to be experienced in professional life.
