Past research on electronic mail (e‐mail) has established this information technology as an effective means for achieving intra‐ and inter‐organizational co‐ordination. Current research on e‐mail has gone beyond the technical aspects of implementation to the non‐technical, namely, the social aspects. This paper follows the current trend by considering the role of leadership in diffusion and implementation of e‐mail. A case study which describes the introduction of e‐mail to a university community, is presented. The diffusion of e‐mail was strongly supported by the charismatic president of the university and was a technical success. It was, however, followed by a series of political events that undermined the leadership of the president. The discussion focuses on how leadership theories, paritcularly current theories on charismatic leadership, can explain the technical success of the project and its turbulent political side‐effects. The conclusions outline implications for managers and information systems practitioners.

Grid‐group analysis is grounded in a humanistic conception of social science but, it is argued, it has flaws when applied to the analysis of the environmental movement. Environmentalism is not “border” country particularly as existing only in opposition to a “centre”. Grid‐group analysis loses clarity when forced into a “border versus centre” format. And the grid‐group analysis of sub‐cultures is not sufficiently well developed; the lack of a clear holistic frame plays havoc with efforts to derive solid policy.

THE re‐organisation of local government in Greater London and the resultant amalgamation of library authorities is viewed by many with considerable misgivings. The upheaval of staff, the loss of status for some senior officers, the general uncertainty for the future—these are very real consequences of the Act and they cannot be ignored. Many chief librarians will see the work of a lifetime, perhaps spent in building up a comprehensive and unified system, made virtually meaningless overnight.

The purpose of this descriptive study is to investigate why some elementary children have difficulties mastering addition and subtraction calculation tasks.

The researchers have examined error types in addition and subtraction calculation made by 697 Portuguese students in elementary grades. Each student completed a written assessment of mathematical knowledge. A system code (e.g. FR = failure to regroup) has been used to grade the tests. A reliability check has been performed on 65 per cent randomly selected exams.

Data frequency analyses reveal that the most common type of error was miscalculation for both addition (n = 164; 38.6 per cent) and subtraction (n = 180; 21.7 per cent). The second most common error type was related to failure to regroup in addition (n = 74; 17.5 per cent) and subtraction (n = 139; 16.3 per cent). Frequency of error types by grade level has been provided. Findings from the hierarchical regression analyses indicate that students’ performance differences emerged as a function of error types which indicated students’ types of difficulties.

There are several limitations of this study: the use of a convenient sample; all schools were located in the northern region of Portugal; the limited number of problems; and the time of the year of assessment.

Students’ errors suggested that their performance in calculation tasks is related to conceptual and procedural knowledge and skills. Error analysis allows teachers to better understand the individual performance of a diverse group and to tailor instruction to ensure that all students have an opportunity to succeed in mathematics.

Error analysis helps teachers uncover individual students’ difficulties and deliver meaningful instruction to all students.

This paper adds to the international literature on error analysis and reinforces its value in diagnosing students’ type and severity of math difficulties.

Most of the chapters in this book depict local attempts to transform practices in early childhood education. They represent endeavors to problematize the complexities and challenges facing the field and the ways in which moves are being made in everyday classroom practice, policy, teacher education, and professional development to build a knowledge base that is grounded in empirical data and that reflects the diversity characteristic of a globalized society.

Purpose – Stemming from extant literature on consumer brand narratives and the rising quest for consumption authenticity, the chapter aims at merging these two streams of knowledge. How can brand authenticity be defined and narrated? To what extent do companies and consumers interact? What are the consequences for branding?

Methodology – The chapter is case-based, and illustrates the branding strategy of l’Occitane en Provence, a company producing toiletries with a strong Mediterranean rooting. Data were collected through multisited ethnographic fieldwork in Paris and Manosque, Haute Provence. Depth and short interviews with customers and managers of l’Occitane were complemented by extensive observation and secondary data. The comprehensive dataset was analyzed consistently with interpretive research tenets.

Findings – Data document (i) five dimensions of brand authenticity contextualized to l’Occitane Mediterranean brand; (ii) the different branding strategies made possible to companies by the varied combination of these five dimensions; and (iii) the distinct profiles of brand consumers according to the specific authentic narrative each of them is more receptive to.

Practical implications – Implications for authentic brand narratives are drawn. I argue that when companies adopt a narrative approach to branding they can establish a stronger dialogue with customers and defend their competitive advantage more effectively. Actually, each brand narrative cannot be easily imitated by competitors since its imitation would turn out as a fake, unauthentic tale for the market.

Originality of the chapter – The chapter contributes to the fields of branding and authenticity, by extending the notion and understanding of consumption authenticity to brands.
