The Role of Agricultural Consultants in New Zealand in Environmental Extension

Abstract

The aim of this study was to understand the role that agricultural consultants in New Zealand were undertaking in the Research, Development and Extension (RD&E) system—and in particular in relation to environmental extension. New Zealand does not have a public extension service and hence there is a strong reliance on consultants and regional councils for environmental management information and advice. As they are independent of the formal RD&E system there is no guarantee that RD&E outcomes are reaching farmers, nor that effective environmental extension is occurring. The study used a combination of case studies, phone interviews with informed persons and a national web survey to explore the role of the consultant. The study found that agricultural consultants are playing an important role in working with farmers to improve agricultural production. There are, however, indications that gaps have developed over time between agricultural consultants and the agricultural research sector which limit the effectiveness of the RD&E system. Agricultural consultants are playing a minimal role in proactive environmental extension because insufficient market forces are driving this role. The paper suggests that a national database of agricultural consultants could improve the flow of tailored information between research and agricultural consultants and also suggests mechanisms where consultants could be better integrated into the RD&E system and provide feedback to research programs. Market failure in the area of environmental extension could be addressed by publicly funded incentive programs.     

Integrating technical editing students into a multidisciplinary engineering project

A three‐year experiment in integrating technical editing students into a multidisciplinary engineering design project developed several ways of helping students apply classroom learning to practical problems. Each year, the engineering students formed Integrated Product Teams (IPTs) and the technical editing students provided editorial support, first as full members of IPTs, then as separate editorial support teams. Research from cooperative learning and teamwork indicates strategies and techniques for best integrating the technical editing students.     

Models and Strategies for Factor Mixture Analysis: An Example Concerning the Structure Underlying Psychological Disorders

The factor mixture model (FMM) uses a hybrid of both categorical and continuous latent variables. The FMM is a good model for the underlying structure of psychopathology because the use of both categorical and continuous latent variables allows the structure to be simultaneously categorical and dimensional. This is useful because both diagnostic class membership and the range of severity within and across diagnostic classes can be modeled concurrently. Although the conceptualization of the FMM has been explained in the literature, the use of the FMM is still not prevalent. One reason is that there is little research about how such models should be applied in practice and, once a well-fitting model is obtained, how it should be interpreted. In this article, the FMM is explored by studying a real data example on conduct disorder. By exploring this example, this article aims to explain the different formulations of the FMM, the various steps in building a FMM, and how to decide between an FMM and alternative models.     

Student-centredness: the link between transforming students and transforming ourselves

It is widely accepted in the higher education literature that a student-centred approach is pedagogically superior to a teacher-centred approach. In this paper, we explore the notion of student-centredness as a threshold concept and the implications this might have for academic staff development. We argue that the term student-centred in the Rogerian sense implies a focus on the person of the student and is deeply resonant with Barnett's assertion that the emergent being of the student is as important as the development of skills and knowledge. To facilitate transformative learning in higher education an academic must know how to value the person of the student in the learning process. Academic staff development initiatives need to work with the person of the academic and take into account the level of personal development required for each academic to be able to facilitate this kind of learning.     

The long tail: a usage analysis of pre-1993 print biomedical journal literature

Objective: The research analyzes usage of a major biomedical library''s pre-1993 print journal collection.Methodology: In July 2003, in preparation for a renovation and expansion project, the Biomedical Library at the University of California, San Diego, moved all of its pre-1993 journal volumes off-site, with the exception of twenty-two heavily used titles. Patrons wishing to consult one of these stored volumes could request that it be delivered to the library for their use. In the spring of 2006, an analysis was made of these requests.Results: By July of 2006, 79,827 journal volumes published in 1992 or earlier had been requested from storage. The number of requests received declined with age of publication. The usage distribution exhibited a “long tail”: 50% of the 79,827 requests were for journal volumes published before 1986. The availability of electronic access dramatically reduced the chance that corresponding print journal volumes would be requested.Conclusions: The older biomedical print journal literature appears to be of continued value to the biomedical research community. When electronic access was provided to the older literature, demand for older print volumes declined dramatically.

Highlights

• Analysis of requests for stored biomedical journal volumes published prior to 1993 indicates that older biomedical journal literature receives substantial use: during this 3-year study, there were nearly 80,000 requests for journal volumes published in 1992 or earlier, with half the requests for volumes published from 1986–1992 and 40% of the request for volumes published from 1970–1985. These results indicate that retaining older print volumes, or providing easy access to the older literature through electronic journals or other means, will likely be required to meet user information needs.
• Use of older journal volumes varies by title and by user population, and a small number of journal titles were responsible for most of the use.
• Requests for older print biomedical journal titles dropped significantly when electronic access became available.

Implications

• Biomedical libraries should carefully consider implications of eliminating on-site access to older journal literature for users and budgets.
• Removing access to older journal literature may result in higher demand for interlibrary loan and document delivery services.
• Biomedical libraries can safely substitute reliable electronic access to older literature to meet ongoing needs for this information, thereby creating space for other purposes.

     

Construct Validity of Adults’ Retrospective Memory for Childhood TV Viewing: Self-Reported Early Exposure to Violent TV Programs Predicts Current Aggression

Construct validity was investigated of a measure of remote past television viewing in which adults reported their childhood viewing of specific television series. Good recall of past viewing was predicted due to two robust memory capabilities, specifically, high accuracy at estimating frequency of exposure to stimuli, and durable long-term memories for repeatedly-encountered material. Validity was tested by examining relationships between self-reported childhood TV viewing and current aggression. Results indicated that recalled childhood viewing of programs containing violent content was positively related to adult aggressive behavior directly, and aggressive cognitions indirectly, independently of adult exposure to violent TV programs, exposure to nonviolent TV programs, parental disciplinary style, and sex. A valid self-report measure of remote past TV viewing behavior can enable researchers to examine, in a relatively quick and inexpensive manner, long-term relationships between early viewing of any television content and any later psychological outcomes of interest.     

Pointing to parallels in ability-related differences in the use of metacognition in academic and psychomotor tasks

This paper offers a brief review of the use of metacognition by proficient and poor performers in academic and psychomotor tasks as well as highlights the parallels and provides directions for future research. Metacognition is knowledge about one's own cognitive processes [Flavell, J.H. (1979). Metacognition and cognitive monitoring: A new area of cognitive-developmental inquiry. American Psychologist, 34, 906–911.]. To date, the study of the use of metacognition by children with different levels of abilities (from those having a learning disability to those identified as gifted) has been mostly restricted to the cognitive abilities in academic areas such as reading, writing, or mathematics. The structure of knowledge has been more extensively explored in the expertise literature in the performance of both academic and psychomotor tasks. Similarities have been noted in the characteristic differences between experts and novices in both these types of tasks. Studies have begun to explore the use of metacognition in psychomotor tasks such as key strokes, ball throwing–catching, and running. It seems that, as with the structure of knowledge, parallels also exist in the use of metacognition by poor and proficient performers in academic and psychomotor tasks.
