This paper aims to investigate how to promote two types of knowledge contribution tasks. The authors focus on the role of supervisor and coworker support on motivation, and their effects on two different contribution tasks. Motivating employees to contribute knowledge is quite challenging. While previous studies have tried to understand how to promote knowledge contribution, few have differentiated between knowledge contribution tasks.

Information technology support was chosen as the context of this study, and data were collected from system administrators within a Fortune 500 company via a web-based survey.

Results show the differential effects of two forms of motivation on different contribution tasks, and supervisor support is positively associated with intrinsic motivation. Specifically, while intrinsic motivation is positively associated with challenging knowledge contribution, external motivation is positively related to mundane knowledge contribution and negatively related to challenging knowledge contribution.

This study contributes to the current literature by providing a deeper theoretical understanding of knowledge contribution tasks, and contributes to practice by offering suggestions on how to better motivate employees within organizations and promote different knowledge contribution tasks.

This paper reviews the current literature of knowledge management systems (KMS) studies in organizations. The authors systematically review the literature according to the principle of innovation studies approach, i.e. variance and process approaches. The purpose of this paper is to identify the current state of KMS studies in organizations. By doing this, the way is paved for the authors to find the research gaps, which would facilatively suggest the direction for future research. The authors hope that this review will be regarded as a source for those who share mutual interests in KMS research and could stimulate further research being conducted in the area with different approaches in the future.

Journal articles published within the period 2003‐2013 were collected. The articles were sourced mainly from Emerald, Science Direct, IEEE, MIS Quarterly, as well as some other academic databases. The search was conducted using such keywords as “knowledge management system” “knowledge repository” “knowledge management tools” “system for knowledge management” and “knowledge‐based system”.

It was found that the majority of KMS studies primarily pertain to adoption, diffusion, usage, and implementation, which are fundamentally based on a variance approach. The studies based on a process approach, however, are found to be scarce and still lacking. The authors highlight the findings and provide a critical review of the current approach, as well as commenting on the traditional theories that have been applied, unified, and modified for the studies of KMS in organizations. The authors also suggest some appropriate approaches to studying KMS in organizations and future directions for further research in this field.

The paper has produced a certain result of review studies from the existing literature during the period 2003‐2013. However, the review mainly focused on different approaches that looked into the classification of study schemes and theories being applied for research, while not focusing on other aspects that may be relevant to the area of studies.

The result of this review highlights some gaps in the literature in terms of findings and critical observation of the theoretical and methodological approaches to the research of KMS studies in organizations. Directions for future research are suggested.

To identify features of teacher support associated with children who made accelerated progress in writing in an early literacy intervention.

Mixed methods were used to describe the paths, rates, variability, and potential sources of change in the writing development of 24 first grade students who participated in an early literacy intervention for 20 weeks. To describe the breadth and variability of change in children’s writing within a co-constructed setting, two groups who made high and low progress were identified.

We focus on one child, Paul, who made high progress (became more independent in the writing of linguistically complex messages) and the features of teacher support that this child received compared to those who made lower progress. We compare him to another child, Emma, who made low progress. Teacher support associated with high progress included a conversational style and flexibility to adapt to the child’s message intent as the student composed, supporting students to write linguistically more complex and legible messages, and supporting students to orchestrate a broad range of problem-solving behaviors while writing.

We describe how teachers can support children to gradually take control of the composition process, how they can recognize complexity in early written messages and we provide suggestions as to how teachers can systematically assess, observe, and support children’s self-regulation of the writing process.

Elasto‐plastic models based on critical state formulations have been successful in describing many of the most important features of the mechanical behaviour of soils. This review paper deals with the applications of this class of models to the numerical analysis of geotechnical problems. After a brief overview of the development of the models, the basic critical state formulation is presented together with the main modifications which have actually been used in computational applications. The problems associated with the numerical implementation of this type of models are then discussed. Finally, a summary of reported computational applications and some specific examples of analyses of geotechnical problems using critical state models are presented.

Purpose – The aim of this work is to provide a global 3D finite element (FE) model devoted to the modelling of superficial soil ploughing in the large deformation range and for a vast class of soil treatment tools. Design/methodology/approach – We introduced soil constitutive equation in a FE software initially designed for the metal forming. We performed the numerical integration of the non‐linear ploughing problem. Non‐linearities encountered by the problem can be summed up: as soil constitutive equation (idealized with non‐associated compressible plastic law), unilateral frictional contact conditions (with a rigid body), geometrical non‐linearities (the ploughing tool) and large deformation range. To handle such difficulties we performed several numerical methods as implicit temporal scheme, Newton‐Raphson, non‐symmetric iterative solver, as well as proper approximation on stress and strain measures. Findings – Main results deal with the validation of the integration of the non‐linear constitutive equation in the code and a parametric study of the ploughing process. The influence of tool geometric parameters on the soil deformation modes and on the force experienced on the tools had been point out. As well, the influence of soil characteristics as compressibility had been analyzed. Research limitations/implications – This research is devoted to perform a numerical model applicable for a large range of soil treatment tools and for a large class of soil. However, taking into account all kind of soil is utopist. So limitations met are essentially related to the limit of the accuracy of the elasto‐plastic idealization for the soil. Practical implications – In practice the numerical model exposed in the paper can clearly help to improve and optimize any process involving superficial soil submitted to the mechanical action of a rigid body. Originality/value – The original value of the paper is to provide a global and an applicable numerical model able to take into account the main topics related to the ploughing of superficial soils. Industrials in geotechnics, in agriculture or in military purposes can benefit in using such numerical model.
