Effect of Cycloplegia on Blur Perception Thresholds as Measured by Source Method

2017

Abstract One of the advantages of a source method over observer method in blur perception measurements is better control of a stimulus blur level, which is achieved with computerised image processing unlike the observer method that requires optical defocusing of the observer. The aim of this study was to determine if paralysation of accommodation has effect on blur perception thresholds, thereby evaluating its necessity in such experiments. Blur perception thresholds (just noticeable blur, clear image, recognition, and non-resolvable blur thresholds) were evaluated with (using cycloplegia) and without paralysed accommodation to determine effect on blur perception. A computerised low-pass sp…

Hierarchies of knowledge, incommensurabilities and silences in South African ECD policy: Whose knowledge counts?

2017

AbstractPolicy for young children in South Africa is now receiving high-level government support through the ANC’s renewed commitment to redress poverty and inequity and creating ‘a better life for all’ as promised before the 1994 election. In this article, I explore the power relations, knowledge hierarchies and discourses of childhood, family and society in National Curriculum Framework (NCF) as it relates to children’s everyday contexts. I throw light on how the curriculum’s discourses relate to the diverse South African settings, child rearing practices and world-views, and how they interact with normative discourses of South African policy and global early childhood frameworks. The NCF…

Revealing colonial power relations in early childhood policy making: An autoethnographic story on selective evidence

2021

The COVID-19 pandemic exposes uncertainty, instability and glaring inequality that requires urgent global policy decisions. Historically, bureaucrats regard uncertainty as the enemy and look for tested solutions (Stevens, 2011). In contrast, Fielding & Moss (2010) acknowledge an uncertain future and encourage shifting policy making towards the search for possibilities instead of replicating singular solutions. Escobar (2020) advocates for pluriversal politics, with many possibilities created through collective decision-making by autonomous interlinked networks. In this paper, I combine autoethnography with policy analysis drawing on my own experience in South African early childhood pol…

Mapping soil water content under sparse vegetation and changeable sky conditions: comparison of two thermal inertia approaches

2013

A critical analysis of a thermal inertia approach to map surface soil water content on bare and sparsely vegetated soils by means of remotely sensed data is reported. The study area is an experimental field located in Barrax, Spain. In situ data were acquired within the Barrax 2011 research project. An advanced hyperspectral scanner airborne imager provides images in the visible/near-infrared and thermal infrared bands. Images were acquired both in day and night times by the Instituto Nacional de Técnica Aeroespacial between 12th and 13th of June 2011. The scene covers a corn irrigation pivot surrounded by bare soil, where a set of in situ data have been collected both previously and simult…

“Never shake thy gory locks at me” (Macbeth, III.iv.50-51): Objecting to Gestures in Macbeth

2018

International audience; Shakespeare's Macbeth displays a pattern of characters objecting to gestures, be it others' or their own. This includes Macbeth refusing to shake hands with his opponent before the battle, his words to Banquo's ghost quoted in the title above, Banquo's own puzzlement at the weird sisters' placing a finger over their lips, the doctor's suspicions at Lady Macbeth's rubbing her hands and sleepwalking, as well as Malcom's request that Macduff not pull his hat over his eyes. In many of these cases, gesture is pitted against speech, which seems to undermine the classically-derived ideal of "suit[ing] the word to the action, the action to the word" (Hamlet, 3.2.16-18). This…

The everyday and spectacle of subdued citizenship in northern Uganda

2019

Drawing on ethnographic research in the Acholi town of Kitgum in northern Uganda, this chapter illustrates how citizenship practices are embedded in particular relationships between the state and its citizens. Two key arenas for learning are identified: the everyday, which in this region is tinged by memories of past violence and fears of its recurrence, and moments of spectacular state performance such as the burial of a prominent politician. The chapter shows how practices of citizenship are learned through embodied experiences: by taking part in public debate, by voting or by greeting a flag, but also by running away from a soldier or by staying quiet due to fear. The chapter’s overall a…

Studying the Cognitive Map of the US States: Ideology and Prosperity Stereotypes Predict Interstate Prejudice

2018

What are the spontaneous stereotypes that U.S. citizens hold about the U.S. states? We complemented insights from theory-driven approaches to this question with insights from a novel data-driven approach. Based on pile sorting and spatial arrangement similarity ratings for the states, we computed two cognitive maps of the states. Based on ratings for the states on ∼20 candidate dimensions, we interpreted the dimensions that spanned the two maps (Studies 1 and 2). Consistent with the agency/socioeconomic success, conservative-progressive beliefs, and communion (ABC) model of spontaneous stereotypes, these dimensions that participants spontaneously used to rate the states’ similarity included…

The implications of teachers’ implicit theories for moral education: A case study from Finland

2017

Implicit theories concerning the malleability of human qualities are known to have a powerful impact on motivation and learning, but their role in moral education is an under-researched topic. In this qualitative case study, we examined the impact of implicit theories on four Finnish teachers’ practices of teaching morally and in teaching morality. The data include preliminary and stimulated recall interviews (STR) as well as classroom observations. Our results demonstrate the multiple ways in which teachers’ implicit beliefs are communicated to students and influence teacher’s interpretations and endeavors to educate the ethical capabilities of students. The study provides evidence for the…
