While “meaning negotiation” has become an ubiquitous term, its use is often confusing. A negotiation problem implies not only a convenience to agree, but also diverging interest on what to agree upon. It implies agreement but also the possibility of (voluntary) disagreement. In this chapter, we look at meaning negotiation as the process through which agents starting from different preferred concep

En teknik för att förhindra yterosion och samla ytavrinning är bygga jordvallar (1–1,5 m höga) parallellt medhöjdkurvorna. Denna teknik används över stora områden i Tunisien. I denna studie undersöks hur dessa jord-vallar påverkar ytjordens rumsliga variabilitet av markvattenhalt (θ) och salinitet, dels uttryckt som jordenstotala elektriska konduktivitet (σa) och dels som porvattnets elektriska koOne technique for collecting rainwater and prevent soil erosion applied on large areas in Tunisia involves theuse of soil ridges (1–1.5 m high). These contour ridges are constructed parallel to topographical isolines. Theeffects of the contour ridges on the soil water content (θ) distribution, bulk soil salinity σa, and soil water salin-ity (σw) were investigated in the catchment of El-Gouazine in

Purpose: The purpose of this paper is to describe a review of the most frequently cited English articles of five models of collaborative professional development for mathematics teachers, aiming to describe the character of the development addressed and its quality issues. Design/methodology/approach: The most frequently cited articles were chosen for their impact on the scientific discourse; they

Purpose – The purpose of this paper is to describe a learning study with a complex object of learning – democracy. Design/methodology/approach – The study consists of four research lessons in four different classes in grade 6. In the study two teachers, 78 students and two researchers participated. In the first lesson (A) 21 students participated, in the second class (B) 17, in the third class (C)

To link geophysical field data to specific biological phenomena, controlled laboratory experiments are needed for the understanding of the response of geophysical parameters to changes in biological conditions. In this study, suspensions of bacteria were mixed with sand to create a biofilm growing on a surface and these mixtures were monitored using the geoelectrical spectral induced polarization

Biological diversity encompasses the genetic diversity within each species, the range of species in a given ecosystem e.g. species diversity and the diversity of ecosystems across an entire region (Primack, 2000). At present 1 per cent of the world’s described species are threatened with extinction. The most pervasive and overriding threat is habitat loss and degradation due to human activity such
