CS preexposure: Latent inhibition and Pavlovian conditioning of heart rate and eyeblink responses as a function of sex and CS intensity in rabbits

Male and female rabbits received Pavlovian conditioning in which a 1, 216-Hz tone served as the CS and a 3-mA paraorbital electric shock train served as the US. Eyeblink (EB) and heart rate (HR) CRs were assessed. Half of the animals received prior exposure to the CS, while half were restrained in the chamber for a similar length of time but did not receive prior CS exposure. Different groups of each sex received three different CS intensities including 60, 75, and 90 dB (SPL) during both preexposure and conditioning. The results revealed that latent inhibition of the EB CR occurred only at the intermediate CS intensity, as indicated by a significant impairment of EB conditioning in this group. However, the magnitude of the decelerative HR CR was attenuated by prior CS exposure at all three CS intensities. Females showed faster EB conditioning than males, but latent inhibition occurred in both sexes. These results suggest that somatomotor and autonomic systems are affected differently by prior CS exposure.     

Work-Based Learning: Effectiveness in Information Systems Training and Development

The ability to use methodologies is an essential ingredient in the teaching of Information System techniques and approaches. One method to achieve this is to use a practical approach where students undertake ‘live’ projects with local client organisations. They can then reflect on the approach adopted with the aim of producing a ‘reflective methodological practitioner’. This paper focuses on the use of experiential learning in a modular course at the University of Central Lancashire to produce these ‘methodological practitioners’ and is based on the experiences of the authors in running this module. A model is presented which outlines three viewpoints of the project. This is in line with a ‘soft systems’ perspective in analysing the three views of the project or problem situation. It reports the results of investigations into one of those viewpoints [that of the students]. This is approached by a survey undertaken amongst students to obtain their views on the determinants of project success and failure.     

Women scholars: Closing the publication gap

As more females receive advanced degrees in business and enter the field of teaching in higher education, the role of females as publishers in scholarly journals will increase. Data collected from 27 business-oriented journals covering a 23-year time period support this premise. The purpose of this article is to present that data in order to show the changing role of women in publishing and to highlight some of the similarities and differences between female and male authors.     

Making the Invisible Visible. On Participation and Communication in a Global, Web-based Master’s Programme

This study focuses on the discourse of an intercontinental on-line Master’s programme in adult learning, using English as the lingua franca of the programme and involving four collaborating universities in Sweden, South Africa, Canada and Australia. The programme is highly interactive, emphasising communication between students. Taking the variation in participation as the point of departure, a discourse analysis aiming at analysing the contingencies contributing to the pattern of communication in the programme was undertaken. Data consist of a variety of texts on-line web-documents, written notes, and narratives that participants wrote about their lives related to participation in the programme. The use of English as the lingua franca contributed to a mistake anxiety, which for some students was hampering their communication in the programme. Aspects of the material world such as the vast differences in the efforts and costs for participating in the programme were also highly interrelated to the shaping of socio-culturally situated identities among the students and thereby contributing to the variation in frequency in participation. The results show that the official discourse of the programme as a text, with its emphasis on equity, change and development, gets subordinated to the discourses produced and reproduced by the students in the programme as a discursive practice and social practice. The students’ accounts reveal that there are fragments of an alternative discourse emerging, based on mutual concern and friendship, which might suggest a potential for changing the communicative patterns in the programme.     

Control strategies and noncompliance in abusive mother-child dyads: an observational study

The present observational study of child abuse has isolated parental control strategies and child response as a promising area of investigation. The social interaction of 10 abusive and 10 matched control mothers and their preschool children was videotaped in a simulated home environment involving both structured and unstructured activities. A coding scheme was developed to record interactional behavior in each dyad. Particular emphasis was placed on the analysis of mother command/child compliance sequences. Compared to controls, abusive mothers employed more commands, and more power-assertive and less positively oriented control strategies. They were also more intrusive, more inconsistent in their use of parenting techniques, displayed more flattened affect throughout their control interactions, and were less flexible in their attempts to gain compliance from the child. In turn, children of abusive mothers demonstrated far more noncompliant behavior than their control counterparts.     

STAFF AND PEER ASSESSMENT ‐ MEASURING AN INDIVIDUAL'S CONTRIBUTION TO GROUP PERFORMANCE

Group Modelling is expanding in the UK and has provided a suitable medium for Communication training at Robert Gordon's Institute of Technology. The CNAA has approved a scheme in which 10% of the marks in Mathematical Models and Methods course are peer awarded. The criteria which students use are not cited explicitly because the scheme wishes to reflect the shift from staff‐sponsored instruction to self/peer sponsored perception of relationships and the tender of solutions. The scheme provides the opportunity to measure what happens outside class contact hours and is proving an effective method of group assessment.     

Rhetorical Analysis of Stakeholders in Environmental Communication: A Model

This article examines contributions of selected theories to technical communication's understanding of environmental discourse and uses a dialogical synthesis to construct a model of stakeholder analysis. The model, with its interactive variables of stakeholder knowledge, attitude, and desired behavior, is applied to a pollution prevention document and calls for an active research emphasis in determining effective communication strategies.     

Opening dimensions of variation: An empirical study of learning in a Web-based discussion

The discussions held in specifying an automaticvehicle as a project in a distance work-relatedcourse are in focus for an analysis of learningin networked discussions. Learning ischaracterised as coming to experience things indistinctly new ways, in keeping with theunderlying phenomenographic research approachfor the study. Group discussions are seen asone feature in the experience of, and theformation of, the context for learning, in anexperiential interpretation of activitysystems. The analysis has led to theidentification of pivotal contributions todiscussions that can be said to afford learningwithin the group, in the sense of openingdimensions of variation around criticalfeatures of the task. This is developed toproduce a taxonomy of contributions, withparticipatory, factual, reflective and learningcontributions, suggested to be necessary,though not sufficient, conditions for learning.The taxonomy is illustrated and discussed, asare its implications for tutoring in networkedcourses of this type.
