The launch of innovative product-related services: Lessons from automotive telematics     

Sylvain Lenfle  Christophe Midler 《Research Policy》2009,38(1):156-169

In the literature on new product development, most existing studies on the end of the design process concentrate on managing ramp-up in the field of manufactured products. This situation poses a problem at a time when our economies increasingly depend upon services and products are more and more related with sophisticated services that provide value for customers and producers. This article examines the management of the final phases of the design process of an innovative product-related service. Our research thus makes three contributions: (1) an analysis of the implementation process shows that the simultaneity of the production and consumption of a service means that three types of learning - technical, sales and uses - take place at the same time. Launch management strategies have thus to be adapted; (2) an analysis of the data collected confirms this difference by bringing to light great contrasts in these different aspects of learning; (3) this led us to identify a field that needs exploration by researchers in product and service innovation: the design of the sales process. Furthermore we underline two scenarios to manage the launch of innovative product-related services.  相似文献   

Upending the Grammar of the Conventional Religious School     

Isa Aron 《Journal of Jewish Education》2014,80(3):193-228

This article provides an overview and analysis of a relatively new phenomenon: congregational schools that have altered the conventional grammar of schooling, either through their structural arrangements or through their curricular approaches. Five pre-bar/bat mitzvah models are discussed: family schools, schools as communities, informal / experiential programs, afterschool/day care programs, and those that deconstruct and reconstruct the conventional model. In addition, three curricular innovations are examined: project based learning, learning organized around the interests and abilities of the students, and Hebrew Through Movement. Also considered are the factors that are necessary to the survival and proliferation of these new structures and curricular arrangements.  相似文献   

Toddlers Default to Canonical Surface‐to‐Meaning Mapping When Learning Verbs     

Isabelle Dautriche  Alejandrina Cristia  Perrine Brusini  Sylvia Yuan  Cynthia Fisher  Anne Christophe 《Child development》2014,85(3):1168-1180

Previous work has shown that toddlers readily encode each noun in the sentence as a distinct argument of the verb. However, languages allow multiple mappings between form and meaning that do not fit this canonical format. Two experiments examined French 28‐month‐olds' interpretation of right‐dislocated sentences (noun_i‐verb, noun_i) where the presence of clear, language‐specific cues should block such a canonical mapping. Toddlers (N = 96) interpreted novel verbs embedded in these sentences as transitive, disregarding prosodic cues to dislocation (Experiment 1) but correctly interpreted right‐dislocated sentences containing well‐known verbs (Experiment 2). These results suggest that toddlers can integrate multiple cues in ideal conditions, but default to canonical surface‐to‐meaning mapping when extracting structural information about novel verbs in semantically impoverished conditions.  相似文献   

Vocational education,on-the-job training,and labour market integration of young workers in urban West Africa     

Christophe J. Nordman  Laure Pasquier-Doumer 《Prospects》2014,44(3):445-462

Young people in Africa encounter many difficulties in entering the labour market and in searching for decent and productive jobs. Research on the links between formal education and vocational training and their economic returns are especially crucial in understanding the inadequate demand for their labour. This article presents evidence based on the 1-2-3 Surveys conducted in seven West African countries; the surveys provide a consistent and comparable picture of the urban youth employment situation in these countries. The analysis also indicates that vocational education could be helpful in integrating the formal sector and that it often offers better earnings and better firm performance than general education, especially at higher levels of schooling. Overall, young workers with no formal vocational education and training face poorer working conditions, while those who have had a traditional apprenticeship in a small firm occupy an intermediate position. Finally, on-the-job training plays a crucial role in the informal sector of the West African cities.  相似文献   

Deaf parents and pediatric cochlear implantation: an exploration of the decision-making process   总被引：1，自引：0，他引：1  

Hardonk S  Daniels S  Desnerck G  Loots G  Van Hove G  Van Kerschaver E  Sigurjónsdóttir HB  Vanroelen C  Louckx F 《American annals of the deaf》2011,156(3):290-304

The study examined factors in deaf parents' decision between cochlear implantation (CI) and traditional hearing aids for their child. The subjects were 6 Flemish children ages 5-9 years with severe/profound congenital hearing loss, with at least 1 deaf parent. The researchers, who conducted thematic content analysis of qualitative data collected through parent interviews, found that with the exception of a family with 1 hearing parent, parents gave priority to Deaf identity, sign language, and ethical issues in deciding between CI and hearing aids. Medical risks were also mentioned. The researchers conclude that the decision-making processes of the parents involved factors that have also been found among hearing parents, as well as aspects that have not been reported to play a role in hearing parents' decision making. A further conclusion is that deaf parents' perspective merits attention in professional practice and empirical research.  相似文献

Developmental changes in the comparison of decimal fractions     

Laetitia Desmet  Jacques Grégoire  Christophe Mussolin 《Learning and Instruction》2010,20(6):521-532

Learning about decimal fractions is difficult because it requires an extension of the number concept built on natural numbers. The aim of the present study was to investigate developmental changes in children's misconceptions in decimal fraction processing. A large sample of children from Grades 3 to 6 performed a numerical comparison task on different categories of pairs of decimal fractions. The success rate and the type of error they made varied with age and categories. We distinguished the impact of the value of the digits from the impact of the length of the fractional part on children's pattern of responses. Although both kinds of impact affected the success rate, the digit values had a stronger impact and were mastered later than the length. Our results also showed that a zero just after the decimal point was understood better and earlier than a zero at the end of the fractional part of a number. Cluster analysis was conducted to determine groups of children who answered similarly regarding the response type across the various categories of decimal fractions. To interpret the data the conceptual change framework was used.  相似文献   

An assessment model for proof comprehension in undergraduate mathematics     

Juan Pablo Mejia-Ramos  Evan Fuller  Keith Weber  Kathryn Rhoads  Aron Samkoff 《Educational Studies in Mathematics》2012,79(1):3-18

Although proof comprehension is fundamental in advanced undergraduate mathematics courses, there has been limited research on what it means to understand a mathematical proof at this level and how such understanding can be assessed. In this paper, we address these issues by presenting a multidimensional model for assessing proof comprehension in undergraduate mathematics. Building on Yang and Lin’s (Educational Studies in Mathematics 67:59–76, 2008) model of reading comprehension of proofs in high school geometry, we contend that in undergraduate mathematics a proof is not only understood in terms of the meaning, logical status, and logical chaining of its statements but also in terms of the proof’s high-level ideas, its main components or modules, the methods it employs, and how it relates to specific examples. We illustrate how each of these types of understanding can be assessed in the context of a proof in number theory.  相似文献
