Modifying the farmer field school method to support on-farm adaptation of complex rice systems

Purpose: Complex rice systems (CRSs) are polycultures of plants and animals that enhance ecological processes contributing to sustainable and profitable farming systems. However, the contextual management complexity can hamper adoption, despite the large long-term benefits that CRSs offer. This paper aimed to provide a method that encourages active farmer involvement and integrates farmer’s feedback to deliver timely adaptations to CRS management.

Design/methodology/approach: FFSs that are commonly used in guiding rural development processes involve a long process of preparation, weekly meetings and dissemination of new technologies with a greater knowledge flows from researchers or institutions to farmers than contrariwise. We have simplified FFS components and modified its curriculum focusing on extracting and integrating farmers’ feedback into adaptation measures. Surveys were conducted and their results were validated through focus group discussions, which provided an adequate database to simplify the steps in the FFS approach.

Findings: Only four meetings for agroecosystems analysis that emphasised an analytical and reflective learning cycle generated suitable adaptation measures selected from farmers’ feedback. Repetition of the shortened FFS over several rice cropping cycles proved more effective than the frequent meetings within one cropping cycle.

Practical implications: The modified FFS could be considered as a promising approach to training farmers, whilst simultaneously identifying and discovering adaptations of agricultural innovations and monitoring the evolution of complex polycultures like CRSs, under diverse conditions.

Theoretical implications: The modified FFS provides participants additional time to reflect on the training topics, resulting in a significant improvement in their knowledge and the performance of the CRS.

Originality/value: The modified FFS approach is focused on reflexive learning cycles and adaptation of innovations. Therefore, it is highly suitable for management of complex polycultures such as CRSs.     

The Role of Stress in the Social Support–Mental Health Relationship

This study examined the mediating effect of psychological stress in the relationship between social support and mental health symptomatology in undergraduate students. Participants (n = 368) completed measures of social support, psychological stress, and mental health symptomatology. Bootstrapping estimates of indirect effects indicated a significant influence of psychological stress in the relationship between social support and both anxiety and depression symptomatology. Implications for mental health promotion and treatment on college campuses are discussed.     

Sociocultural anchors for incorporating sustainability in youth movements: Comparison among secular,religious, and ultraorthodox movements

Abstract

In Israel, youth movements (YMs) comprise a main agent for nonformal education of youth and a youth-engagement framework in which civic engagement can be expanded to address environmental challenges. A major source of sociocultural diversity among YMs is their religious identity, based on the categorizations of secular, religious, and ultraorthodox. We compared, among these groups, the environmental literacy (EL) characteristics of “young-guides” and YM-leaders’ perspectives of sustainability in relation to their YM. Differences among groups were found in the young-guides’ EL: members of secular YMs demonstrated greater EL and openness to including pro-environmental activities within their YM. “Judaism as a platform for addressing sustainability” emerged as a major theme from leaders’ interviews. Implications for meaningful incorporation of sustainability and EE within the groups are discussed.     

Language skills and cognitive processes related to poor reading comprehension performance

Eleven tests were administered to 20 high school readers with learning disabilities (LD) and 20 controls. The objective was to examine the relation between reading comprehension performance and performance on tests of language skills and cognitive processes. As a whole, the performance of the group with LD was significantly below the performance of the controls on all measures. However, the variance on nonverbal tests was greater for the group with LD than for controls; some individuals with learning disabilities performed as well as the controls. Results are discussed in terms of how performance deficits are amenable to remediation by instruction.     

‘A strategy of distinction’ unfolds: unsettling the undergraduate outbound mobility experience

Although short-term mobility programmes are increasingly promoted to university students as sources of competitive advantage, there is little research on academic learnings arising from these initiatives. A ‘field analysis’ of outbound mobility is undertaken to identify convergences and disjunctures between institutional discourses, staff perceptions and student experiences at one Australian university where outbound mobility is actively promoted as a ‘strategy of distinction’. Self-reported ‘personal transformations’ commonly associated with the mobility experience are interrogated in favour of alternative constructions of self–other relationships. An argument is made for greater institutional effort to enable students to make critical connections with ‘other-ness’ both in and out of place.     

Getting started: exploring pre-service teachers’ confidence and knowledge of culturally responsive pedagogy in teaching mathematics and science

Recent changes to the Australian Curriculum reinforce the need for all educators to value the cultures and perspectives of Aboriginal and Torres Strait Islander students. The disproportionately high levels of educational disadvantage experienced by many of these students has prompted the Australian Institute for Teaching and School Leadership to introduce two teacher standards aimed at improving awareness of Aboriginal and Torres Strait Islander cultures and histories, and enactment of pedagogies that support Aboriginal and Torres Strait Islander student learning. We describe a pilot study focussed on one cohort of final year mathematics and science primary/middle pre-service teachers (PSTs) as they navigate these standards. We explore PSTs’ self-reported knowledge and confidence before and after targeted interventions designed to cultivate cultural responsiveness. Although the findings suggest an increase in PSTs’ perceived confidence, further work is needed towards what could be considered culturally responsive pedagogies for early career mathematics and science teachers.     

The effects of calibration amongst management students in higher education

This study contributes to the on-going discourse on calibration among University students. The study examines the understanding of student self-reflectivity in relation to class written tests and assignments, and of the fact that students’ expected results rarely match the actual results. A quantitative research approach was adopted to collect data from third-year and honours management students at a university in South Africa. The sample population for the class test was 105 out of 205 students, while the sample population for the assignment was 71 out of 205 students. The method applied involved asking students to forecast their result before and after the class test or the assignment. The evaluation process involved a comparison of students’ expected results and the actual performance in both cases. The findings reveal that students’ perception and understanding of the questions in the class test and the assignment contribute immensely to their individual performance. A limitation on this study is that data were collected from students within the management discipline only. Insights from this study can be used to develop assessment methods that are in sync with changes in the present-day education environment. The study contributes to an understanding of curriculum development within the context of challenges facing the educational system in South Africa.     

Assessment of integration method for displacement determination using field accelerometer and geophone data

A conventional French railway track was instrumented with accelerometers and geophones at three depths: sleeper (surface), interlayer (ITL, z=?0.93 m), and transition layer (TL, z=?1.20 m). A linear variable differential transformer (LVDT) was also used to monitor the displacement at the sleeper level. The recorded data allow the integration method (double for accelerometer and simple for geophone) for displacement determination to be assessed. Several questions need to be addressed prior to the selection of an adequate monitoring system: definition of signal filtering processes, influence on results of the different loading wavelengths, repeatability of measurements, train speed and axle load impact and their ranges of validity for each sensor. It was found that the main frequencies that caused more than 95% of the displacement of the monitored materials are in the low frequency range: <25 Hz for trains running up to 200 km/h. For an intercity train, the low frequencies are normally excited by long wavelengths, for instance, those corresponding to the 1/2 coach distance (λ=13.20 m), the bogies distance (λ=6.3 m), and the axle distance (λ=2.8 m). Comparison between the displacements deduced from the records of accelerometer and geophone and obtained from the records of LVDT shows quite consistent results; the mean displacement amplitudes obtained from accelerometers differ by only 20% from the LVDT records. The train speed does not have a strong effect on the obtained differences between sensors. The embedded sensors also gave consistent displacement results for each analysed depth. Moreover, the displacement amplitudes caused by different axle loads (locomotive or passenger coach) are distinguishable for all sensors at all depths. This validates the integration method used for the displacement determination.
