Growing monstrous organisms: the construction of anti-GMO visual rhetoric through digital media

This paper explores the international controversy over genetically modified organisms (GMOs). We argue that the uncommonly high levels of opposition to genetically modified food in both the United States and in Europe can be attributed to the overwhelming success of the online visual campaign against GMOs. By exploiting the unique characteristics of the internet to create memetic images that can travel freely across linguistic and cultural borders, opponents of the technology have been able to refute rationalist claims about the safety of GMOs. In response to the single coherent narrative of scientific certainty, a diffuse set of challenges emerges. The risk of genetic engineering holds within it the potential for catastrophe, leaving the industries that produce and manufacture the technology in a perpetual state of crisis. Instead of a unified narrative of scientific certainty, each challenge presents a multiplicity of diffuse narratives that unsettle the public’s understanding of the risk presented by GMOs. We aim to augment traditional understandings of the way that publics may interact with the “public screen” by explicating one way in which dominance of the visual in mediated political discourse may privilege non-rational political decision making.     

Family resources and parenting quality: links to children's cognitive development across the first 3 years

Reciprocal associations among measures of family resources, parenting quality, and child cognitive performance were investigated in an ethnically diverse, low-income sample of 2,089 children and families. Family resources and parenting quality uniquely contributed to children's cognitive performance at 14, 24, and 36 months, and parenting quality mediated the effects of family resources on children's performance at all ages. Parenting quality continued to relate to children's cognitive performance at 24 and 36 months after controlling for earlier measures of parenting quality, family resources, and child performance. Similarly, children's early cognitive performance related to later parenting quality above other measures in the model. Findings merge economic and developmental theories by highlighting reciprocal influences among children's performance, parenting, and family resources over time.     

Changes in and Stability of Cardiovascular Responses to Behavioral Stress: Results from a Four-Year Longitudinal Study of Children

This study examined the changes in and stability of cardiovascular responses to behavioral stress among 132 children in a 4-year longitudinal study. Children's heart rate and blood pressure were measured at rest and while performing 3 tasks: serial subtraction, mirror image tracing, and isometric exercise. This procedure was followed at study entry when children were in grades 2-12 (ages 6-18 years) and at follow-up when children were in grades 6 through post-high school (ages 11-21 years). Results showed that blood pressure and heart rate responses during the tasks were reliable across time for all measures except heart rate responses during isometric exercise. Systolic blood pressure responses to all tasks increased with age for boys, but not for girls. These results support the notion that cardiovascular responses to behavioral stress are a stable individual difference variable.     

‘Timescapes’ in doctoral education: the politics of temporal equity in higher education

ABSTRACT

In the twenty-first century, the politics of higher education in Australia and around the globe have become dominated by neoliberal agendas of efficiency, profitability and managerialism. This has fundamentally altered the ‘timescapes’ of higher education. In the case of doctoral education, doctoral candidates and supervisors are subjected to increasing time pressures and required to produce a wide variety of outcomes in very short timeframes. These managerial agendas of efficiency and speed impact upon all doctoral candidates and supervisors but present particular practical and epistemic difficulties for Indigenous, migrant, refugee and international students. In this article, I illustrate how fast doctoral timescapes encourage assimilationist pedagogies that have been shown to be especially detrimental for Indigenous, migrant, refugee and international doctoral candidates. Drawing upon a complex array of theoretical resources that investigate Lefebvre’s rhythm analysis and other authors’ notions of epistemic time and the ethics of time, this article argues for a reconceptualization of doctoral timescapes in order to promote a politics of temporal equity in doctoral education. This especially involves making space for epistemic, lived and eternal temporal rhythms in doctoral education policy and practice.     

What participatory photography can tell us about immigrant and refugee women’s learning in Atlantic Canada

Migration is a gendered phenomenon, embedded within patriarchal structures and social relations that extend beyond State borders. We draw on a transnational feminist framework to explore the gendered dimensions of young refugee and immigrant women’s migration and learning experiences. Ten women were involved in a participatory photography research project over a period of two years in which they took and shared photographs, and engaged in storytelling and self-reflection through writing and dialogue. Through the photo-stories, the women demonstrate the plurality of refugees’ and immigrants’ stories and how these contribute to the larger social analysis of what it is to be an immigrant or refugee woman in Atlantic Canada. We focus this paper on three key themes: (1) formal and informal learning experiences; (2) the essential role relationships play in the women’s migration experiences; and (3) the importance of reflecting on and embracing life’s journeys.     

Mid-career academic women and the prestige economy

Drawing on 30 semi-structured interviews with women academics based in London higher education institutions in the UK, this paper investigates the gendered nature of the prestige economy in academia. We explore how mid-career academic women strategise their career development and the opportunities and barriers they perceive, particularly in relation to the accrual of academic esteem. Concept maps were used to facilitate dialogue about career plans and provided an artefact from the interviewee’s own perspective. The analysis draws on the concept of prestige, or the indicators of esteem that help advance academic careers, against the backdrop of a higher education context which increasingly relies on quantitative data to make judgements about academic excellence. The interviews indicated that women generally feel that men access status and indicators of esteem more easily than they do. Many women also had ambivalent feelings about gaining recognition through prestige: they understood the importance of status and knew the ‘rules of the game’, but were critical of these rules and sometimes reluctant to overtly pursue prestige. The findings are valuable for understanding how women’s slow access to the highest levels of higher education institutions is shaped by the value that organisations place on individual status.     

Developing Collaboration Skills in Team Undergraduate Research Experiences

Abstract

Interdisciplinary undergraduate research experiences often require students to work in teams with other students and researchers from different disciplines, creating a need for development of new skills in interdisciplinary collaboration. In this paper, we describe our unique efforts to mentor participants in developing these skills during our team-based research experience for undergraduates program. This effort was initiated in response to a perceived need to provide professional development in collaboration for our participants, who come from diverse backgrounds that span a range of disciplines, institutions, and cultures. We describe here the intervention used, which is a modified version of one successfully implemented in a classroom setting. Furthermore, we present our formative and summative program evaluation data regarding participants’ perceptions about what helps or hinders team science. The most-repeated themes in student evaluations, in order from most mentions to least, were: communication, goal setting, shared mental model, timing/scheduling, cooperation, non-participation, attitudes, and mentor guidance/support. Together these themes account for 82% of the student responses. Lastly, we present our observations of the positive effects of this intervention on our program. Our findings may be useful to those mentoring undergraduates in both team research and classroom group learning.     

Analyzing Mathematical Tasks: A Catalyst for Change?

In this study we investigate a strategy for engaging high school mathematics teachers in an initial examination of their teaching in a way that is non-threatening and at the same time effectively supports the development of teachers’ pedagogical content knowledge [Shulman (1986). Educational Researcher, 15(2), 4–14]. Based on the work undertaken by the QUASAR project with middle school mathematics teachers, we engaged a group of seven high school mathematics teachers in learning about the Levels of Cognitive Demand, a set of criteria that can be used to examine mathematical tasks critically. Using qualitative methods of data collection and analysis, we sought to understand how focusing the teachers on critically examining mathematical tasks influenced their thinking about the nature of mathematical tasks as well as their choice of tasks to use in their classrooms. Our research indicates that the teachers showed growth in the ways that they consider tasks, and that some of the teachers changed their patterns of task choice. Further, this study provides a new research instrument for measuring teachers’ growth in pedagogical content knowledge. An earlier version of this paper was presented at the American Educational Research Association Annual Meeting, New Orleans, LA, April 2002.

A Comparison of General and Content-Specific Literacy Strategies for Learning Science Content

This study employed an adapted alternating treatments single-case design to explore students’ learning of biology content when using a general note-taking (GNT) strategy and a content-specific graphic organizer (CGO) to support reading high school biology texts. The 4 focal participants were 15–18-year-olds committed to a moderate risk juvenile justice facility. Lessons were delivered once a week for 7 weeks with CGO delivered first in odd weeks and GNT first in even weeks. When students were unfamiliar with the strategies or experiencing emotional or health problems, their weekly quiz scores tended to be higher on whichever lesson was delivered first. After stabilizing, an average ability reader did better on CGO lessons, and a student with below-average reading ability did better on GNT lessons. CGO took more time to prepare but an average of 11 minutes less than each GNT lesson to implement. CGO also was associated with more student-initiated responses and more self-reported student preferences.
