The paper considers aberrant behaviour in the context of cognitive style with reference to both diagnosis and treatment.

Aims.

The aims of the study were to investigate whether the style of pupils with behaviour problems was different from that of children with no reported problems, and also to consider how pupils of different style manifested their problem behaviours.

Sample.

The sample comprised 83 male pupils aged 10‐18 years from two residential special schools.

Method.

The sample were given the Cognitive Styles Analysis to assess their positions on the Wholist‐Analytic and Verbal‐Imagery style dimensions. The pupil records of the special school pupils who were at the extreme of the style dimensions were also examined.

Results.

When their style characteristics were contrasted with a Comparison Sample of 413 12‐16‐year‐old males attending 10 secondary schools, the special school pupils had a significantly higher proportion of both Wholists and Verbalisers, than the Comparison Group. Further, the inspection of the records indicated that the types of social behaviour and behaviour problems exhibited varied with style, and particularly on the Wholist‐Analytic dimension.

Conclusion.

The results were considered to have implications for the origins and treatment of problem behaviour.  相似文献

Purpose: To examine the factors that support and hinder farmers’ learning and to investigate the impact of an innovative learning program on farmers’ practice change.

Design/methodology/approach: Individual interviews and focus group discussions were held with 24 farmers over 20 months. Observations were made of these farmers as they participated with eight agricultural and social scientists in a range of innovative experiences to learn about chicory and plantain establishment and management. These learning experiences were designed around evidence-informed educational pedagogies. Data sets were analyzed using NVivo to determine common themes of affordances and barriers to learning and actual practice changes.

Findings: The affordances for learning and practice change include belonging to a learning community, enhancing self-efficacy, engaging with scientists, seeing relative advantage, reinforcing and validating learning, supporting system’s integration and developing an identity as learners. Barriers to learning and practice change include issues of: trialability, complexity, compatibility and risk.

Practical implications: The importance of basing new models of extension around evidence-informed pedagogies known through educational research to promote learning and practice change.

Theoretical implications: Sociocultural theory and self-efficacy theories of learning are critical to the success of effective agricultural extension programs.

Originality: To date, little empirical research about the affordances and barriers for pastoral farmers’ learning has been based on contemporary educational research.  相似文献

Purpose: The key informants in a village setup were studied to understand the existing social and knowledge systems of farmers, their structure, and relationships between different actors. The purpose is to identify different channels of information and use them as a means to disseminate agricultural technologies and related information to farmers.

Design: We use the network map analysis in a case study approach as a tool to demonstrate the linkages between the key actors and stakeholders in the information network of farmers.

Findings: The government institutions are well networked among themselves but have limited interactions with non-government sources. Farmers in Bihar have strong linkages with few network actors, who are important nodes in the social knowledge network. The study showed heterogeneity and complexity in the network shape and structure across different districts.

Practical Implications: Knowledge networks and social networks are the drivers of information sharing and play a significant role in the diffusion of agricultural technology and related knowledge. Understanding these networks provides a platform for introducing the agricultural technologies and getting connected to a wider group of farming communities.

Theoretical Implications: The study shows that the network is formed by different actors and their role determine the nature and shape of the network. Knowledge of this heterogeneity is important in designing or revamping agricultural information systems.

Originality: Information and knowledge networks are least explored in the agricultural information dissemination process. Some studies have shown the role of actors and social networks, but this study uniquely explores and presents the heterogeneity of these networks.  相似文献

Purpose: This study uses data from a sample of 150 oilseed farming households from Arsi Robe, Ethiopia, to assess the impact of different knowledge bases (education, training and experience) and their interactions on linseed productivity.

Methodology: A multiple regression analysis was employed to assess the combined effect of the knowledge bases, factors such as age of the household head, land size, marketing channels and geophysical factors (such as land slope) on linseed productivity.

Findings: The findings reveal no differences in productivity between trained and untrained farmers. They further show that training and the interaction between training and experience positively influence productivity. Our findings, however, reveal farmer education to have an inverse yet insignificant effect on productivity. Furthermore, we found that factors such as the slope of the land and the choice of marketing channel also play an important role in influencing productivity.

Practical implications: Moving away from the traditional top-down approach could be the answer to avoid a mismatch between the information given by trainers and what the farmers actually need.

Theoretical implications: The study used interaction variables of knowledge bases, and attempted to demonstrate the importance of a tacit knowledge base, which is often not well documented and therefore neglected in research.

Originality/value: The research demonstrates the combined effects that interactions between several knowledge bases have on the productivity of linseed farmers.  相似文献

Purpose: This paper presents economic and pedagogical motivations for adopting information and communications technology (ICT)-mediated learning networks in agricultural education and extension. It proposes a framework for networked learning in agricultural extension and contributes a theoretical and case-based rationale for adopting the networked learning paradigm.

Design/methodology/approach: A review of the literature highlights the economic and pedagogical need for adopting a networked learning approach. Two examples are described to instantiate the language for learning networks: a small community of farmers in India and large Twitter community of Australian farmers.

Findings: This paper reviews evidence that successful networked learning interventions are already occurring within agricultural extension. It provides a framework for describing these interventions and for helping future designers of learning networks in agricultural extension.

Practical implication: Facilitation of learning networks can serve to achieve efficient agricultural extension that connects farmers across distances for constructivist learning. To realize these benefits, designers of learning networks need to consider set design, social design and epistemic design.

Theoretical implication: This paper contributes a theoretical framework for designing, implementing and analysing learning networks in agriculture. It does this by integrating existing ideas from networked learning and applying them to the agricultural context through examples.

Originality/value: This paper contributes an understanding of the value of networked learning for extension in terms of economic and pedagogical benefits. It provides a language for talking about learning networks that is useful for future researchers and for practitioners.  相似文献

Purpose: In this paper, we discuss the role of participatory research in integrated agricultural technology development using the example of a solar fruit drying project in Mozambique.

Design/methodology/approach: We engage in seven participatory exercises with groups of farmers from two farmers’ associations in Inharrime district in Mozambique to identify their needs for solar fruit drying that are crucial for solar dryer technology design. We focus in the analysis on three of these exercises including a daily schedule exercise, SWOT (Strengths Weaknesses Opportunities and Threats) analysis and technology requirement exercise.

Findings: Participatory research takes a dual function for integrated agricultural technology development. First, it can help to identify the technology needs of farmers and second it can enable the exchange and creation of different sets of knowledge for agricultural technology development between multiple stakeholders.

Practical implications: Participatory research provides a tool for joint knowledge exchange and creation, which allows the identified technology requirements to be translated into practical technology design.

Theoretical implications: This paper extends the concept of integrated research to integrated agricultural technology development and shows how participatory research is a tool that enables transdisciplinarity, which presents the most desired form of integrated research.

Originality: This research is highly relevant for researchers working in an interdisciplinary environment with agricultural technology development in cross-cultural contexts. From a meta-level perspective, it provides insights for joint and integrated technology development.  相似文献

Purpose: In this study, we use a self-determination theory (SDT) approach to understand farmers’ attitudes toward, and intentions for, participation in competence development projects (CDP).

Design/methodology/approach: By applying SDT, we developed two measures. The first one assessed the degree to which the three basic human psychological needs motivate farmers to engage in CDP, and the second concerned farmers’ intrinsic and extrinsic motivation to seek knowledge through participation in CDP. Using data from two samples of farmers, we examined the effect of SDT needs and the influence of the different regulatory styles on individuals’ decision to participate in CDP.

Findings: Our findings indicated that participation in CDP is guided by the most internal forms of human motivation (identified, integrated, and intrinsic motivation), and that deficits in the needs for autonomy and competence predict farmers’ decision to participate in CDP.

Practical implications: These results stress the importance of designing CDP that promote self-directedness, emphasise choice rather than rewards, and generate the conditions that support farmers’ autonomy.

Theoretical implications: Our work suggests that the integration of social psychology into extension/education research can paint a more detailed picture of the way farmers interact with extension/education services.

Originality/value: To the best of our knowledge, this is the first study that uses an SDT framework to examine farmers’ motivation toward participation in CDP. Hence, this research opens a new realm for extension/education research, while it also contributes to the SDT literature by examining the role of self-determined motivation in a different life domain.  相似文献

Purpose: This study examines the suitability of the system of rice intensification (SRI) for diverse small-scale farmers in Tanzania by exploring if poor and non-poor farmers adopt the system to a similar extent.

Originality: The suitability of low-external input technologies such as SRI for diverse African farmers is a contentious issue. Existing studies suggest that adoption may be skewed away from poorer farmers, but no studies have explicitly categorized farmers who participate in adoption of SRI.

Methods: Farmers exposed to SRI were randomly surveyed. Sample farmers were categorized into three socioeconomic groups – wealthier, middle-wealth, and poorer – using factor and cluster analysis approaches. Wealth category is then used in a logit model to determine probabilities of adopting SRI practices across the different groups.

Findings: The results indicate that middle-wealth group adopt SRI to a greater extent compared to the wealthier and poorer groups. The extent of adoption by wealthier and poorer groups is similar, although constraining circumstances differ. Access to factors that consistently explained adoption: contact with extension services, land with water, and labor, vary systematically among groups.

Theoretical implication: Low adoption is often assumed on reduced exposure to a technology, and non-adopters are expected to eventually adopt. The results suggest, however, that farmers, who have not adopted, may not do so, even after being exposed. SRI as a package does not fit their socioeconomic conditions.

Practical implications: To support adoption across all wealth categories, extension should focus on promoting individual practices rather than the package to enable farmers adopt practices that fit their socioeconomic characteristics.  相似文献

Purpose: Participation in labour markets and high-value crops among men and women smallholder farmers has always been an important strategy for poverty alleviation and attainment of food and income security. In contributing to the generation of gender-disaggregated empirical literature, this paper examined determinants of women smallholder farmers’ participation in their households’ decision-making regarding cash crop production.

Methodology: Data for the paper were sourced from a baseline survey conducted by Monitory and Evaluation Technical Support Services, Institute of Statistical, Social and Economic Research and Ghana Statistical Service for the USAID Feed the Future Programme in their Northern Ghana Zone of Influence. The data were analysed using probit regression analysis to identify factors which significantly influence women farmers’ participation in cash crop production.

Findings: The probit analysis identified intra-household power relations such as women participation in household decision-making, control over household productive resources and control over household income as significant determinants of smallholder women farmers’ participation in cash crop production.

Theoretical Implication: Improving women smallholder farmers’ power to participate in household decision-making, access to and control over household productive resources and income are therefore imperative in boosting women farmers’ participation in cash crop production.

Practical Implications: It is therefore recommended that any gender-targeted policy and programme with the aim of women’s economic empowerment must critically examine the sociocultural barriers impeding women’s participation in their household decision-making and control over household productive resources. Women farmers’ participation in their households’ decision-making regarding cash crop production and the use of income generated from it should be encouraged through gender mainstreaming in agricultural service delivery.  相似文献

Purpose: The purpose of this study is to develop a conceptual framework with related analysis methodologies that identifies the influence of social environment on an established cropping system.

Design/methodology/approach: A stratified survey including 103 villages and 823 farmers was conducted in all districts of Haryana (India). Firstly, technical efficiency (TE) was modeled using biophysical data including grain yield, seeding rate, wheat varieties, tillage, sowing date, seed source, harvesting method and the application of fertilizer, herbicide and irrigation. The relationship between TE and social community factors such as farm size, farmer age, level of education and agricultural support programs was analyzed by regression tree.

Findings: TE was lower with the farmers who only have education to a primary standard. Farmers with high TE scores were mostly between 35 and 40 years of age, and a higher TE association was common for farmers who use technical publications. Social individual factors such as farmers’ views on the future of farming were also analyzed across different TE levels.

Practical implications: Farmers with lower TE are an obvious target for production improvement, particularly given the understanding that the overall production yield gap is small in Haryana.

Theoretical implications: Our conceptual framework shows a quantitative way to establish the socio-ecological linkage, and to identify the opportunities for changes in management with extension services leading to productivity improvement.

Originality/value: This paper provides a novel framework with detailed methodology to effectively identify the socio-economic factors that limit the biophysical production in an agricultural system.  相似文献

Purpose: This study evaluates the impact of an outsourced extension service delivered by Lima Rural Development Foundation (Lima) in the Umzimkhulu district of South Africa. The evaluation is conducted at both the household and program levels.

Design/methodology/approach: Household impacts were estimated using two-stage regression with instrumental variables to account for selection bias. Gains in household income were extrapolated to estimate the net incremental benefit of the program and its financial return at district level. These analyses were underpinned by a rigorous sampling design.

Findings: The results show that the outsourced extension service made a significant and substantial contribution to household crop income and net income. In addition, clients perceived a range of socio-economic benefits such as better diets, improved product quality, and job creation. Analysis of the financial cost and benefit of the extension service at district level suggests an annual net incremental benefit of R5 million (US$0.4 million), and a 95% probability that returns to the service exceeded 20% in 2012/2013.

Practical implications: These results suggest that there is good reason for donors to continue funding effective extension services to small farmers in areas of high agricultural potential.

Theoretical implications: This is an empirical study. It uses well-established methods to measure the impact but introduces a local economy multiplier to capture some of the indirect effects of agricultural extension.

Originality/value: This research is valuable as very few studies worldwide have evaluated the impact of agricultural extension services at both the farm and program levels.  相似文献

Purpose: The aim of this paper is to comparatively assess the most suitable channels for dissemination of agricultural innovations along the entire information value chain.

Design/Methodology/Approach: We calculated information scores to measure channel preference from a randomly selected sample of farmers: 285 in Tamale, Ghana and 300 in Kakamega, Kenya. Using t-tests we compared the information score differences of different channels between farmers who adopted Integrated Soil Fertility Management and those who did not.

Findings: The highest information scores were observed for radio along the entire value chain for both locations. However, farmers in Tamale prefered interpersonal channels for processing information. Radio and farmer field days had the highest rankings for production information at both locations. Radio, workshops and interpersonal channels (traders and neighbours/friends/relatives) were best-bet channels for marketing and procesing information.

Practical implication: Extension agents should place more emphasis on channels such as radio, farmer field days, and workshops as they may offer more efficient delivery of information packages at all levels, whilst recognizing the central role of interpersonal channels.

Theoretical implication: The nexus between the uses and gratification, adoption, diffusion of innovations theories and the collaborative communication theory on one hand, and the agricultural product value chain framework on the other, is highlighted. Farmers’ preference for information channels is not predicated on the stage of the value chain.

Originality/Value: In the current context of weak agricultural knowledge and innovation systems in African agriculture, agricultural producers are poorly informed about the current innovations. This study furnishes empirical evidence on the best-bet information channels to be used by extension workers and change agents to disseminate and communicate system innovations.  相似文献

Purpose: This paper examines the factors affecting farmers’ participation in extension programs and adoption of improved seed varieties in the hills of rural Nepal.

Methodology/approach: Cross-sectional farm-level data were collected during July and August 2014. A sample of 198 farm households was selected for interviewing by using a multistage, random sampling technique. We employed a logistic regression model, frequency counts, and percentages to analyze the data.

Findings: Adoption decisions were mainly affected by extension-related variables – training, membership in a farmers’ group, and off-farm employment. Extension participation was found to be influenced by socioeconomic variables – age, education, household size, and distance to the extension office. Our findings reveal that distance to the extension office and off-farm employment limited participation in extension activities and adoption, respectively, and education, household size, and group membership stimulated participation in extension programs.

Practical implications: Recognition of the determinants of farmers’ participation in extension services and innovation adoption ensures that targeted extension approaches are used to address these factors in various stages of planning, delivering, and evaluating extension programs.

Theoretical implications: Innovation adoption follows a systematic decision-making process. Although personal characteristics are important, widespread use of new technology requires a conducive social and institutional context. Because contexts vary by country or region, extension services providers should create institutions favorable for innovation adoption within a social system.

Originality/value: This research is original and highly valuable to identify the factors associated with extension participation and innovation adoption in the rural hilly region of Nepal. This also provides a new direction to operationalize farmer-oriented policies of agricultural extension and so can be helpful for agricultural policy-makers in devising programs of extension services.  相似文献

Purpose: Meat processing companies have the potential to raise farm and sector productivity by directly working with farmers. This study assesses how commercial companies can undertake the roles of innovation intermediaries to increase productivity in New Zealand’s sheep and beef sector.

Design/methodology/approach: This study uses a case study approach from the red meat sector in New Zealand. The case study included the development of a trial agricultural extension system established by staff from meat processing companies acting as innovation intermediaries, providing opportunities for skill development and knowledge transfer for farmers. From the case study, a framework is developed which illustrates how company staff can undertake the role of an innovation intermediary.

Findings: (1) Meat processing company staff are able to successfully undertake the role of an innovation intermediary; (2) flexibility is necessary, as staff undertook each of the functions to different degrees depending on their existing skills and knowledge of agricultural extension and the time available within their current job; and (3) adaptability is important, as staff adapted the project to meet the needs of both farmers and their employer.

Practical implications: Balancing commercial and extension roles is challenging. The framework could assist companies to clarify how individual company staff could successfully undertake specific roles.

Theoretical implications: This paper discusses factors influencing which innovation intermediary roles and functions are optimally undertaken by staff within or outside a meat processing company.

Originality/value: Analysing the role of an innovation intermediary from the perspective of meat processing company staff balancing their extension and commercial role.  相似文献

Purpose: We examine the nature of networks through which new hybrid banana varieties (HBVs) in Uganda are developed, and how different actors engage in the technology development process.

Design/methodology/approach: We collected the data through 20 key informant interviews and 5 focus group discussions with actors involved in the process. We analysed the data with NVivo and Social Network Analysis software.

Findings: The process of developing HBVs involves many actors with a diversity of roles and interests. The network density was 29.4, implying existence of only 29.4% of the possible direct linkages. Strong ties mainly existed among research-oriented actors, with other actors in the periphery.

Practical implications: The current position of smallholder farmers and other non-research actors inhibits their influence on decisions in the technology development process. We recommend that smallholder farmers should be empowered through better organization so that they can influence the process of developing HBVs. Researchers, supported with appropriate policies, should engage more with actors in the intermediary, enterprise and support service domains for a more vibrant agricultural research system.

Theoretical implications: Application of the systems approach to technology development requires a dynamic process that supports involvement of a diverse range of actors. However, close attention to context is important in dealing with issues of power asymmetries and determining to what extent various actors engage in the process.

Originality/value: This work contributes to literature on systems approaches to agricultural and rural development. The paper demonstrates that actor diversity and interactions are critical in technology development and uptake.  相似文献

Purpose: The limited uptake of improved agricultural practices in Africa raise questions on the functionality of current agricultural research systems. Our purpose is to explore the capacity for local innovation within the research systems of Ethiopia, Malawi and Mozambique.

Design/methodology/approach: Using Conservation Agriculture (CA) as a case study, we qualitatively explore with 26 locally based agricultural researchers the context of CA research and promotion, including their perceptions on persistent research gaps and issues in closing them.

Findings: Respondents identified that CA was not yet a finished product, with concerns regarding the benefit, feasibility and relevance of CA implementation. They asserted that while further adaptation was required, they were unable to do this due to institutional constraints within their research, extension and policy contexts.

Practical implications: We find that CA continues to be considered a donor-driven intervention in its current form and requires substantial further adaptation to local contexts before researchers will deem it ready for farmer uptake. The five research gaps identified by respondents highlight practical areas where further adaptations must occur.

Theoretical implications: Our findings suggest a lack of participatory research and extension most likely reflects limited financial, human and social capital to implement more participatory approaches. Without addressing these capacities, widespread adoption of complex farming systems change appears unlikely.

Originality/Value: Whilst many studies have identified a need for local innovation to enable CA utilisation, few have qualitatively explored directly with local researchers the capacity of such systems to do so. We address this gap in the literature.  相似文献

The case is stated for a scheme of professional training for adult educators, which should at once be

_____ comprehensive and unified;

_____ able to take into account the particular possibilities of individual adult educators; and

_____ easily adjustable to the particular needs within the community.

Such a scheme can only be realized through the application of a modular structure. A scheme like this is being developed at Gwent College of Higher Education for a professional training programme which will give a Certificate in Continuing Education, conferring full teacher status in adult and further education. This development is used to illustrate the points the author wants to make. The development of a programme on such a scheme raises considerable structural and methodological problems, which are discussed and compared with what is done elsewhere.  相似文献
