The prevention, treatment and management of disease are closely linked to how the causes of a particular disease are explained. For multi-factorial conditions, the causal explanations are inevitably complex and competing models may exist to explain the same condition. Selecting one particular causal explanation over another will carry practical and ethical consequences that are acutely relevant for health policy. In this paper our focus is two-fold; the different models of causal explanation that are put forward within current scientific literature for (...) the high and rising prevalence of the common complex conditions of coronary artery disease and type 2 diabetes mellitus ; and how these explanations are taken up within national health policy guidelines. We examine the causal explanations for these two conditions through a systematic database search of current scientific literature. By identifying different causal explanations we propose a three-tier taxonomy of the most prominent models of explanations: evolutionary, lifecourse, and lifestyle and environment. We elaborate this taxonomy with a micro-level thematic analysis to illustrate how some explanations are semantically and rhetorically foregrounded over others. We then investigate the uptake of the scientific causal explanations in health policy documents with regard to the prevention and management recommendations of current National Service Frameworks for CAD and T2D. Our findings indicate a lack of congruence between the complexity and frequent overlap of causal explanations evident in the scientific literature and the predominant focus on lifestyle recommendations found in the mainstream health policy documents.

The sudden move to online learning due to the COVID-19 pandemic has created an influx of epistemological, psycho-social, emotional and financial challenges for first year students. Lecturers and academics had to find creative and sustainable ways of ensuring that all students were epistemologically included. New policies and practices were introduced rapidly at universities to facilitate the unavoidable move to online learning. As initial teacher educators at a public University in South Africa we noted that the sudden move to working online (...) has presented various challenges to first year students’ overall well-being which has further exacerbated issues of exclusion and marginalization for many. We argue that it is against this backdrop that this paper explores how the move to online learning has affected first year students’ overall well-being, at one teacher education institution. The Index for Inclusive Education was used as a theoretical lens to explore student’s perceptions of the institution’s policy, teaching and learning practices, and the institutional culture during this period. One hundred and eighty-seven purposively selected first year students participated in this qualitative, phenomenological research study. Data were collected by means of open-ended questionnaires. Responses were categorized by means of an emergent thematic analysis. The findings indicated that online learning compromised various aspects of well-being including physical, emotional, psycho-social and financial well-being for many students. The experiences of online learning and impact on well-being did, however, differ across students depending on their individual contexts and circumstances indicating that considerations of well-being need to take contextual realities into account to support the well-being and learning of all. We recommend that higher education institutions prioritize the psycho-social, emotional, and financial well-being of students during the period of online learning and not just the pedagogic needs of the qualification.

Research has shown that observers automatically align their attention with another’s gaze direction. The present study investigates whether inferring another’s attended location affects the observer’s attention in the same way as observing their gaze direction. In two experiments, we used a laterally oriented virtual human head to prime one of two laterally presented targets. Experiment 1 showed that, in contrast to the agent with closed eyes, observing the agent with open eyes facilitated the observer’s alignment of attention with the primed (...) target location. Experiment 2, where either sunglasses or occluders concealed the agent’s eye direction, showed that only the agent with the sunglasses facilitated the observer’s alignment of attention with the target location. Taken together, the data demonstrate that head orientation alone is not sufficient to trigger a shift in the observer’s attention, that gaze direction is crucial to this process, and that inferring the region to which another person is attending does facilitate the alignment of attention.

Humans are experts in cooperating with each other when trying to accomplish tasks they cannot achieve alone. Recent studies of joint action have shown that when performing tasks together people strongly rely on the neurocognitive mechanisms that they also use when performing actions individually, that is, they predict the consequences of their co‐actor’s behavior through internal action simulation. Context‐sensitive action monitoring and action selection processes, however, are relatively underrated but crucial ingredients of joint action. In the present paper, we try (...) to correct the somewhat simplified view on joint action by reviewing recent studies of joint action simulation, monitoring, and selection while emphasizing the intricate interrelationships between these processes. We complement our review by defining the contours of a neurologically plausible computational framework of joint action. (shrink)

One way in which the practice of inclusion can be actualised in classrooms is through the use of consistent, appropriate differentiated instruction. What remains elusive, however, is insight into what teachers in different contexts think and believe about differentiation, how consistently they differentiate instruction and what challenges they experience in doing so. In the study reported on here high school classrooms in a private and a government school in Lesotho were compared in order to determine teachers’ thoughts and beliefs about (...) differentiation, the frequency of differentiated instruction, and the challenges faced by teachers who implement this inclusive practice. Sampled teachers offered their views on what they understood differentiated instruction to be, the frequency of differentiated instruction, and identified challenges via an administered questionnaire. Data analysis was based on frequency counts and bar charts for comparative purposes. Findings indicate that private school teachers have a higher frequency of differentiated teaching practice, with time constraints indicated as the main challenge. Government school teachers had a lower frequency of differentiation, and identified a lack of resources, and the learner-teacher ratio as challenges, among others. In the study we highlighted the critical role that private schools can play in the national call for the implementation of inclusive teaching in Lesotho, in terms of active collaboration with surrounding government schools. Private schools, with their resources and access to professional development opportunities, can become catalysts in the implementation of inclusive teaching practices. (shrink)

We focus on Byrne & Russon's argument that program-level imitation is driven by hierarchically organized goals, and the related claim that to establish whether observed behavior is evidence of program-level imitation, empirical studies of imitation must use multi-stage actions as imitative tasks. We agree that goals play an indispensable role in the generation of action and imitative behavior but argue that multi-goal tasks, not only multi-stage tasks, reveal program-level imitation.

Background: Although inclusive education is widely discussed, its implementation has not, arguably, been far-reaching. There remains a lack of specific, targeted approaches towards fully including learners with physical and mental impairments in the educational space. Objectives: This study investigated the extent of the inclusion of learners with autism spectrum disorder (ASD) in three schools in Johannesburg. Method: A qualitative interpretivist design was adopted. Teachers who work with learners with ASD were interviewed using open-ended questions. The sampled data were analysed using (...) thematic analysis, making use of both a priori codes and emergent codes that arose from the open-ended questions. Results: The findings reveal numerous pedagogic strategies such as differentiation, scaffolding, use of visual cues, group work and collaboration that can include learners with ASD in the classroom space. Conclusion: Teacher collaboration and teacher training are vital in ensuring that learners with ASD are fully included in the classroom space. (shrink)

Three experiments investigated the nature of visuo-auditory crossmodal cueing in a triadic setting: participants had to detect an auditory signal while observing another agent’s head facing one of the two laterally positioned auditory sources. Experiment 1 showed that when the agent’s eyes were open, sounds originating on the side of the agent’s gaze were detected faster than sounds originating on the side of the agent’s visible ear; when the agent’s eyes were closed this pat-tern of responses was reversed. Two additional (...) experiments showed that the results were sensitive to whether participants could infer a hearing function on the part of the agent. When no ear was depicted on the agent, only a gaze-side advantage was observed , but when the agent’s ear was covered , an ear side advantage was observed only when hearing could still be inferred but not when hearing was inferred to be diminished . The findings are discussed in the context of inferential and simulation processes and joint attention mechanisms. (shrink)

ABSTRACTWhen processing information about human faces, we have to integrate different sources of information like skin colour and emotional expression. In 3 experiments, we investigated how these features are processed in a top-down manner when task instructions determine the relevance of features, and in a bottom-up manner when the stimulus features themselves determine process priority. In Experiment 1, participants learned to respond with approach-avoidance movements to faces that presented both emotion and colour features. For each participant, only one of these (...) two features was task-relevant while the other one could be ignored. In contrast to our predictions, we found better learning of task-irrelevant colour when emotion was task-relevant than vice versa. Experiment 2 showed that the learning of task-irrelevant emotional information was improved in general when participants’ awareness was increased by adding NoGo-trials. Experiment 3 replicated these results... (shrink)

Although applauding Pickering & Garrod's (P&G's) attempt to ground language use in the ideomotor perception-action link, which provides an of embodied social interaction, we suggest that it needs to be complemented by an additional control mechanism that modulates its operation in the service of the language users' communicative intentions. Implications for intergroup relationships and intercultural communication are discussed.

In the opening chapter of his thirty-sixth oration, Dio Chrysostom tells his listeners how in the course of a journey ‘through the lands of the Scythians to that of the Getae’, he stopped over in the city of Borysthenes ‘in the summer after my exile’. Dio had been exiled by Domitian, probably in a.d. 83 or 84; since his exile ended after the death of Domitian in September 96, it is generally accepted that his visit to Borysthenes took place in (...) the summer of 97.

In a world filled with “ambient violence”, public protest is a vital signal of shared discontent. The essential compulsion at the heart of protest, however, is conventionally not recognised for what it is: solidarity with those suffering injustices. Amid authorities’ often-fierce efforts to curtail gatherings of people whose experiences of injustice propel them into the streets, a sharp rise in public protests has been perceived since the early 2000s. Thousands of column inches dedicated to reporting on protests are rivalled in (...) volume only by the reams of academic theories produced around causes. Despite this overabundance of discourses, it often remains unclear what protest, at heart, constitutes. That is, what are we talking about when we talk about protest, and why does this question matter? In this paper I consider the constituent parts of protest formation in the abstract, including grievances, gestures, and tactics, among other. Developing these constituent parts reveals protest to be, first and foremost, a manifestation of a nonhegemonic ethical commitment to justice, requiring courage and coordination, and whose outcome is always contingent, that is, an act of love. I also reflect on the nature of protest as a direct political action that sits on a continuum that ranges from opposition politics to civil war. This continuum offers a graded view ranking expressions of discontent by severity of outcome. (shrink)

The present commentary considers the question of what must be learned in different types of motor skills, thereby limiting the question of what should be adjusted in the APG model in order to explain successful learning. It is concluded that an open loop model like the APG might well be able to describe the learning pattern of motor skills in a stable, predictable environment. Recent research on saccadic plasticity, however, illustrates that motor skills performed in an unpredictable environment depend heavily (...) on sensory (mostly visual) feedback, [HOUK et al.].

Researchers are increasingly expected to deliver “socially robust knowledge” that is not only scientifically reliable but also takes into account demands from societal actors. This article focuses on an empirical example where these additional criteria are explicitly organized into research settings. We investigate how the multiple “accountabilities” are managed in such “responsive research settings.” This article provides an empirical account of such an organizational format: the Dutch Academic Collaborative Centres for Public Health. We present a cross-case analysis of four collaborative (...) research projects conducted within this context. We build on Miller’s notion of “hybrid management.” The article shows that the extended concept of hybrid management is useful to study the different accountabilities encountered in such settings. We analyze how the collaboration developed and which conflicts or dilemmas arose. We then focus on the different hybrid management strategies used in the collaboration. The empirical material shows how the different aspects of hybrid management feature in various configurations in the four projects. We highlight that hybrid management strategies may be used by different groups or at different moments, may reinforce or contradict each other, and may be more or less effective at different points in time.

According to embodied theories of language (ETLs), word meaning relies on sensorimotor brain areas, generally dedicated to acting and perceiving in the real world. More specifically, words denoting actions are postulated to make use of neural motor areas, while words denoting visual properties draw on the resources of visual brain areas. Therefore, there is a direct correspondence between word meaning and the experience a listener has had with a word's referent on the brain level. Behavioral and neuroimaging studies have provided (...) evidence in favor of ETLs; however, recent studies have also shown that sensorimotor information is recruited in a flexible manner during language comprehension (e.g., Raposo et al. ; Van Dam et al., ), leaving open the question as to what level of language processing sensorimotor activations contribute. In this study, we investigated the time course of modality-specific contributions (i.e., the contribution of action information) as to word processing by manipulating both (a) the linguistic and (b) the action context in which target words were presented. Our results demonstrate that processes reflecting sensorimotor information play a role early in word processing (i.e., within 200 ms of word presentation), but that they are sensitive to the linguistic context in which a word is presented. In other words, when sensorimotor information is activated, it is activated quickly; however, specific words do not reliably activate a consistent sensorimotor pattern. (shrink)

There is a respectable feminist tradition in utopian thought. Dreams and fantasies about gender-equal, women-friendly or female-dominated worlds have been formulated abundantly. However, utopian thinking has also met with severe criticism. By definition, utopias were said to be too idealistic, and of little use in the process of societal change. More recently, it has been stressed that the concept of utopia has been superseded by postmodern awareness, in which general explanations of gender inequality (and, along with them, general utopian views) (...) are disqualified to the benefit of more local and more specific theories. In this book, the reader will find not one general, broadly defined utopia, but instead, a wide array of more or less specific, feminist utopias. Utopias are viewed as preliminary and imaginary goals from which present situations can be revalued and from which strategies for change can be developed. As such, utopias have not lost their significance. (shrink)

Single cell recordings in monkeys provide strong evidence for an important role of the motor system in action understanding. This evidence is backed up by data from studies of the (human) mirror neuron system using neuroimaging or TMS techniques, and behavioral experiments. Although the data acquired from single cell recordings are generally considered to be robust, several debates have shown that the interpretation of these data is far from straightforward. We will show that research based on single-cell recordings allows for (...) unlimited content attribution to mirror neurons. We will argue that a theoretical analysis of the mirroring process, combined with behavioral and brain studies, can provide the necessary limitations. A complexity analysis of the type of processing attributed to the mirror neuron system can help formulate restrictions on what mirroring is and what cognitive functions could, in principle, be explained by a mirror mechanism. We argue that processing at higher levels of abstraction needs assistance of non-mirroring processes to such an extent that subsuming the processes needed to infer goals from actions under the label ?mirroring? is not warranted.
