This study examines the eliciting potential of two tasks, one for proto-imperative and another for protodeclarative communicative intentions. The task to elicit proto-imperative utterances and the scoring form are partially based on Casby and Cumpata's (1986) Protocol for the Assessment of Prelinguistic Intentional Communication (PAPIC). However, a number of modifications are proposed for use with young deaf children. For the protodeclaratives, a new eliciting task called Tac-Tic was created. These tasks were offered to 18 normally developing profoundly deaf toddlers at the ages of 18, 24, and 30 months. Results indicate that both tasks possess sufficient eliciting potential to measure both the prelinguistic and early linguistic "illocutionary force" of profoundly deaf children. Moreover, the new eliciting task Tac-Tic seems to have a higher eliciting potential than the corresponding task used in the PAPIC. For clinical aims, a more adapted and more efficient scoring form than the one Casby and Cumpata used was created. 相似文献

Abstract Consumer concerns about food safety have been steadily growing during the last decade. Along with the recognition of the increasing power from the consumer side of food chains, this has forced agricultural producers to innovate and adapt their production methods. One of those innovations is integrated fruit production (IFP) aiming at providing consumers with specific quality products. The focus in this paper is on the establishment and impact of socio-technical networks that close existing gaps between the consumers' world and the one of producers. Specific attention is paid to the role of extension services and product champions as mediators. The theoretical framework comprises elements of the actor-network theory and economic conventions theory. It is shown that the interaction between the consumers' world and the producers' world results from a mediated interactive process that clearly influences the socially constructed technology. Relevant input from consumers, as well as adequate policy measures are urgently needed in order to realise a successful development of quality networks for fresh food. 相似文献

Public knowledge regarding green energy is limited and there is a perceived lack of information, particularly in the case of biofuels. This study investigates the information seeking behaviour of fuel consumers with regard to biofuels, their preferences for particular elements and channels of information and their trust in information sources. The majority of respondents were interested in many elements of information, and particularly in the tax (dis)advantages associated with biofuels. They prefer to obtain information via newspapers and brochures. Scientists, environmental and consumer organizations and the government are perceived as the most trustworthy sources of information whilst word of mouth sources, journalists and the fuel sector are less well trusted. Four consumer clusters could be distinguished, on the basis of the perceived relative trustworthiness of information sources, and these clusters have significantly different socio-demographic characteristics and preferences for elements and channels of information. 相似文献

Ballet training includes exercises of high and moderate intensities, which require breathing control for a good performance. This study describes the thoracoabdominal motion of professional dancers and compares the breathing patterns between professional dancers and non-dancers. Participants of this study were four male and four female (30.33 ± 4.64 years) professional dancers and four male and four female (22.75 ± 1.49 years) non-dancers. The participants executed two breathing manoeuvres while sitting motionless: quiet breathing (QB) and vital capacity (VC). The 3D coordinates of 32 retro-reflective markers positioned on the trunk were used to calculate the volume of the superior thorax, inferior thorax and abdomen. Principal component analysis was applied in the volume variation of each trunk compartment to search for dominant independent variables in a breathing motion pattern. The correlation coefficient was calculated to verify the coordination between the compartments during the breathing manoeuvres. A predominance of the superior thorax or abdomen movement was found in both groups. The professional ballet dancers have an efficient breathing pattern and maintain the same breathing pattern in QB and VC manoeuvres. On the other hand, the non-dancers group showed relevant changes of the breathing pattern to respond to a greater breathing effort, like in VC. 相似文献

How do people learn about the environment and behave accordingly? What is the cognitive process at the base of this learning mechanism? The present paper is a pilot work investigating the dynamics of individual environmental knowledge on the basis of social capital theory. Using Tsai and Ghoshal’s findings, a well known framework widely accepted in organizational studies which supports the existence of a relationship between structural, relational and cognitive dimensions of social capital, and between social capital and knowledge exchange, these dynamics are then tested in the context of environmental behaviour studies. The quantitative analysis is carried out by means of a structural equation model based on data collected in the Republic of Latvia. Results support main theoretical hypotheses, but several effects are found to be highly sensitive to control variables (residence place dimensions, ethnic affiliation, age, personal income), leading to hypothesise a strong dependency of environmental learning patterns on the socio-demographic, socio-economic and cognitive context. 相似文献

Based on new data, this paper studies the invention disclosure, licensing, and spin-off activities of Max Planck Institute directors over the time period 1985-2004, analyzing their effects on the scientists’ subsequent publication and citation records. Consistent with prior findings, inventing does not adversely affect research output. Mixed results are obtained with regard to commercialization activities. The analysis suggests qualifications to earlier explanations of positive relationships between inventing and publishing. 相似文献
