Social Network Structures among Groundnut Farmers

Abstract

Purpose: Groundnut farmers in East Africa have experienced declines in production despite research and extension efforts to increase productivity. This study examined how social network structures related to acquisition of information about new seed varieties and productivity among groundnut farmers in Uganda and Kenya.

Design/methodology/approach: Data came from face-to-face interviews with a sample of 491 farmers randomly selected from a larger frame purposefully selected to represent farmers who had worked with researchers and farmers who had not, and to represent both male and female farmers. We used social network analysis to visualize and interpret patterns of farmers' networks with regard to information sources, productivity supports and local group affiliations.

Findings: Ugandan farmers primarily used weak ties with researchers and extension agents as sources of information. In contrast, Kenyan farmers used strong ties with close associates. For farmers in both countries weak ties were least associated with productivity. Strong ties, natural factors and farmers' own experience with new varieties were most associated with productivity. The majority of farmers had ties to local groups to strategically pool risks and access available resources.

Practical implications: Visualizing farmers' social networks enables policy-makers and change agents to identify relevant social relationships that could be utilized strategically to increase the capacities of poor farming communities.

Originality/value: The study demonstrates that important differences in social network structures can exist among farmers in similar geographic regions producing similar crops.     

First grade teachers’ knowledge of phonological awareness and code concepts: Examining gains from an intensive form of professional development and corresponding teacher attitudes

The study examined the efficacy of an intensive form of professional development (PD) for building the knowledge of first-grade teachers in the areas of phonological awareness and phonics. The PD featured frequent in-class support from highly knowledgeable mentors for one school year, in addition to an introductory two-day summer institute and monthly workshops. Pre- and post-assessment of participants on a Teacher Knowledge Survey (TKS) indicated weak knowledge of phonological awareness and phonics concepts prior to PD and large, significant gains in each area by year-end. In addition, to investigate factors potentially associated with teachers’ responses to training, a Teacher Attitude Survey (TAS) was administered before and after the PD. The TAS measured teachers’ attitudes regarding PD, external and internal motivation to participate, intentions to actively engage in learning and implementing new instructional methods, sense of self-efficacy as reading instructors, and premises about reading instruction (e.g., about whole language). Attitudes on a subset of these factors, teachers’ initial knowledge scores on the TKS, and years of teaching experience (estimated by age) accounted for significant portions of the variance in performance on the TKS after training.

K-12 online lesson alignment to the principles of Universal Design for Learning: the Khan Academy

The field of K-12 education is being transformed, with an influx of students, including those with identified disabilities, engaging in blended and fully online learning. While online learning shows promise for students with disabilities through flexible content and personalised instruction, concerns regarding accessibility and appropriateness of online learning for this population still exist. In order to examine this concern, researchers developed and used a Universal Design for Learning (UDL) Scan Tool to measure lesson content and alignment with UDL principles, guidelines and checkpoints. Four hundred and seventy-eight math, science and world history Khan Academy lessons were randomly selected and evaluated for this study. The paper highlights the results of the study, in terms of the lessons’ alignment with UDL principles and guidelines, as well as a discussion on limitations and future research.     

Hurricane Sandy Exposure Alters the Development of Neural Reactivity to Negative Stimuli in Children

This study examined whether exposure to Hurricane Sandy‐related stressors altered children's brain response to emotional information. An average of 8 months (M_age = 9.19) before and 9 months after (M_age = 10.95) Hurricane Sandy, 77 children experiencing high (n = 37) and low (n = 40) levels of hurricane‐related stress exposure completed a task in which the late positive potential, a neural index of emotional reactivity, was measured in response to pleasant and unpleasant, compared to neutral, images. From pre‐ to post‐Hurricane Sandy, children with high stress exposure failed to show the same decrease in emotional reactivity to unpleasant versus neutral stimuli as those with low stress exposure. Results provide compelling evidence that exposure to natural disaster‐related stressors alters neural emotional reactivity to negatively valenced information.     

Foreign language reading and spelling in gifted students with dyslexia in secondary education

A few studies suggest that gifted children with dyslexia have better literacy skills than averagely intelligent children with dyslexia. This finding aligns with the hypothesis that giftedness-related factors provide compensation for poor reading. The present study investigated whether, as in the native language (NL), the level of foreign language (FL) literacy of gifted students with dyslexia is higher than the literacy level of averagely intelligent students with dyslexia and whether this difference can be accounted for by the difference in their NL literacy level. The sample consisted of 148 Dutch native speaking secondary school students divided in four groups: dyslexia, gifted/dyslexia, typically developing (TD), and gifted. All students were assessed on word reading and orthographic knowledge in Dutch and English when they were in 7th or 8th grade. A subsample (n = 71) was (re)assessed on Dutch, English, French, and German literacy one year later. Results showed that Dutch gifted students with dyslexia have higher NL literacy levels than averagely intelligent students with dyslexia. As in the NL, a stepwise pattern of group differences was found for English word reading and spelling, i.e., dyslexia < gifted/dyslexia < TD < gifted. However, it was not found for French and German literacy performance. These results point towards compensation: the higher English literacy levels of gifted/dyslexic students compared to their averagely intelligent dyslexic peers result from mechanisms that are unique to English as a FL. Differences in results between FLs are discussed in terms of variation in orthographic transparency and exposure.
