Why don’t pesticide applicators protect themselves? Exploring the use of personal protective equipment among Colombian smallholders

The misuse of personal protective equipment (PPE) during pesticide application was investigated among smallholders in Colombia. The integrative agent-centered (IAC) framework and a logistic regression approach were adopted. The results suggest that the descriptive social norm was significantly influencing PPE use. The following were also important: (1) having experienced pesticide-related health problems; (2) age; (3) the share of pesticide application carried out; and (4) the perception of PPE hindering work. Interestingly, the influence of these factors differed for different pieces of PPE. Since conformity to the social norm is a source of rigidity in the system, behavioral change may take the form of a discontinuous transition. In conclusion, five suggestions for triggering a transition towards more sustainable PPE use are formulated: (1) diversifying targets/tools; (2) addressing structural aspects; (3) sustaining interventions in the long-term; (4) targeting farmers’ learning-by-experience; and (5) targeting PPE use on a collective level.

‘Purpose’ as a way of helping white trainee history teachers engage with diversity issues

Based on a three year action research project, this study examines one strand of that research, namely the impact that ‘purpose’, i.e. exploring the range of rationales for studying a subject, has in helping white trainee teachers embrace cultural and ethnic diversity within their teaching. Through ‘purpose’ trainees explored different reasons why history should be taught (and by implication what content should be taught and how it should be taught) and the relationship of these reasons to diversity. Focusing on ‘purpose’ appears to have a positive impact on many trainees from white, mono-ethnic backgrounds, enabling them to bring diversity into the school curriculum, in this case history teaching. It offers one way to counter concerns about issues of ‘whiteness’ in the teaching profession and by teaching a more relevant curriculum has a potential positive impact on the achievement of students from minority ethnic backgrounds.

Diversity in mathematics assessment equals diversity in opinion?

We undertook a study to investigate the views of both students and staff in our department towards assessment in mathematics, as a precursor to considering increasing the diversity of assessment types. In a survey and focus group there was reasonable agreement amongst the students with regards major themes such as mode of assessment. However, this level of agreement was not seen amongst the staff, where discussions regarding diversity in mathematics assessment definitely revealed a difference of opinion. As a consequence, we feel that the greatest barriers to increasing diversity may be with staff, and so more efforts are needed to communicate to staff the advantages and disadvantages, in order to give them greater confidence in trying a range of assessment types.

Linguistic relativity in SLA: towards a new research programme

The purpose of the current article is to support the investigation of linguistic relativity in second language acquisition and sketch methodological and theoretical prerequisites toward developing the domain into a full research program. We identify and discuss three theoretical-methodological components that we believe are needed to succeed in this enterprise. First, we highlight the importance of using nonverbal methods to study linguistic relativity effects in second language (L2) speakers. The use of nonverbal tasks is necessary in order to avoid the circularity that arises when inferences about nonverbal behavior are made on the basis of verbal evidence alone. Second, we identify and delineate the likely cognitive mechanisms underpinning cognitive restructuring in L2 speakers by introducing the theoretical framework of associative learning. By doing so, we demonstrate that the extent and nature of cognitive restructuring in L2 speakers is essentially a function of variation in individual learners’ trajectories. Third, we offer an in-depth discussion of the factors (e.g., L2 proficiency and L2 use) that characterize those trajectories, anchoring them to the framework of associative learning, and reinterpreting their relative strength in predicting L2 speaker cognition

Intolerance of uncertainty predicts fear extinction in amygdala-ventromedial prefrontal cortical circuitry

Background: Coordination of activity between the amygdala and ventromedial prefrontal cortex (vmPFC) is important for fear-extinction learning. Aberrant recruitment of this circuitry is associated with anxiety disorders. Here, we sought to determine if individual differences in future threat uncertainty sensitivity, a potential risk factor for anxiety disorders, underly compromised recruitment of fear extinction circuitry. Twenty-two healthy subjects completed a cued fear conditioning task with acquisition and extinction phases. During the task, pupil dilation, skin conductance response, and functional magnetic resonance imaging were acquired. We assessed the temporality of fear extinction learning by splitting the extinction phase into early and late extinction. Threat uncertainty sensitivity was measured using self-reported intolerance of uncertainty (IU). Results: During early extinction learning, we found low IU scores to be associated with larger skin conductance responses and right amygdala activity to learned threat vs. safety cues, whereas high IU scores were associated with no skin conductance discrimination and greater activity within the right amygdala to previously learned safety cues. In late extinction learning, low IU scores were associated with successful inhibition of previously learned threat, reflected in comparable skin conductance response and right amgydala activity to learned threat vs. safety cues, whilst high IU scores were associated with continued fear expression to learned threat, indexed by larger skin conductance and amygdala activity to threat vs. safety cues. In addition, high IU scores were associated with greater vmPFC activity to threat vs. safety cues in late extinction. Similar patterns of IU and extinction learning were found for pupil dilation. The results were specific for IU and did not generalize to self-reported trait anxiety. Conclusions: Overall, the neural and psychophysiological patterns observed here suggest high IU individuals to disproportionately generalize threat during times of uncertainty, which subsequently compromises fear extinction learning. More broadly, these findings highlight the potential of intolerance of uncertainty-based mechanisms to help understand pathological fear in anxiety disorders and inform potential treatment targets.

Striking a balance: cultural conflicts or cultural adaptation

This paper explores the cultural representations embedded in the EFL textbooks for Primary English language education in China. In particular, it examines how cultural globalisation and localisation are competing with each other as the educational policy in English attempts to strike a balance between the local culture and ‘western’ culture. Using discourse analysis as an analytical framework, this paper argues that culture as a social construct is constantly evolving and traditions are fused with new cultural values and worldviews brought about by globalisation. As such, the analysis of the textbooks illustrates that culture as a social phenomenon has changed over the decades and glocalisation is gaining new perspectives in English language education in China. Importantly, the analysis shows that new cultural elements have been established and cultural globalisation has taken place when local culture adapt ‘foreign’ cultures to suit local needs. Acknowledging that there are cultural conflicts and competing ideologies in the texts, the paper argues that these conflicts and contradictories can be used to develop students’ critical language awareness and foster their critical analytical abilities. Importantly, the analysis can facilitate the students’ English language learning by providing them with opportunities to read beyond texts per se to cultural politics and practices. Juxtaposing different cultural and ideological perspectives can help students understand that cultural values are socially and politically constructed when they are confronted with complex linguistic and cultural environments in reality.

Typo-resource: developing T&L support materials through collaboration

This paper reports on a collaborative project between staff and students in the Department of Typography & Graphic Communication at the University of Reading The Partnerships in Learning and Teaching (PLanT) project here described is a direct response to student needs for better online support materials. Methodologically, the project embeds user-centred design principles within an iterative process of design development and participant research. This process has underpinned the development of a prototype for an online interface called Typo-Resource. The resulting initial prototype addresses the usability and user experience dimensions of an online learning resource, moving beyond providing tutor-identified sets of resources to a multifaceted, collaborative, and visual platform for peer learning.
