Diverse characteristics of UK organic direct marketing chains
In the past few years, organic direct sales in the UK have grown rapidly. Direct sales are assumed to have short or distinct marketing chains from farm gate to consumer. This paper begins by outlining some current problems with the widely accepted defi nition of organic direct sales and charts some of their diverse characteristics. It goes on to argue that the mix of organic direct and multi-farm direct sales is so diverse that a greater clarification of terms is necessary in order to progress consumer, policy and research understanding

The traditional food market and place: new insights into fresh food provisioning in England
This article adds to on-going debates about food provisioning in England and the relative positioning of supermarkets vis-à -vis other sources of fresh food. Arguing that traditional food markets have been neglected in the agri-food literature, the paper investigates the suggestion that they are at ‘a critical juncture’, with many in decline and others being (re-)gentrified for a wealthier type of customer. Theoretically, the article argues that the ‘internal’ and ‘external’ spaces and places of traditional food markets are tightly interwoven. It draws on database analysis and detailed findings from interviews with market managers, traders and shoppers conducted on markets in contrasting regions of England in the cities of Newcastle and Cambridge. The findings provide new insights by examining the connective spaces and places that link market actors and consumers as fresh food moves across the geographical regions and through the marketplace. Taking a relational view, the paper challenges the suggestion that traditional food markets are at ‘a critical juncture’, arguing that there are unique points of difference on how the traditional food market adapts to rapid retail change, according to its geography, history and the spatial and temporal tensions between traditional and modernised fresh food provisioning systems, and suggests the need for further in-depth research
A visual attention mechanism for autonomous robots controlled by sensorimotor contingencies
Alexander Maye, Dari Trendafilov, Daniel Polani, Andreas Engel, ‘A visual attention mechanism for autonomous robots controlled by sensorimotor contingencies’, paper presented at the International Conference on Intelligent Robots and Systems (IROS) 2015 Workshop on Sensorimotor Contingencies for Robotics, Hamburg, Germany, 2 October, 2015.Robot control architectures that are based on learning the dependencies between robot's actions and the resulting change in sensory input face the fundamental problem that for high-dimensional action and/or sensor spaces, the number of these sensorimotor dependencies can become huge. In this article we present a scenario of a robot that learns to avoid collisions with stationary objects from image-based motion flow and a collision detector. Following an information-theoretic approach, we demonstrate that the robot can infer image regions that facilitate the prediction of imminent collisions. This allows restricting the computation to the domain in the input space that is relevant for the given task, which enables learning sensorimotor contingencies in robots with high-dimensional sensor spaces.Peer reviewedFinal Accepted Versio
Mutual Information as a Measure of Coordination in Collaborative Interaction
Dari Trendafilov, Alexander Maye, D. Polani, Roderick Murray-Smith, Andreas Engel, ‘Mutual Information as a Measure of Coordination in Collaborative Interaction’, paper presented at the British HCI 2015 Workshop on Ubiquitous and Collaborative Computing (iUBICOM), Lincoln, UK, 13 July, 2005.We present an information-theoretic approach for quantifying the level of coordination between cooperating parties engaged in a computer-mediated collaborative interaction. The approach builds on Shannon’s mutual information, as a task-independent objective measure, which captures the level of corelation between the actions of interacting agents. We introduce the approach through two characteristic examples and discuss the challenges in designing a reliable measure and the amount of modelling effort required. Our initial results suggest the potential of this measure in supporting designers of collaborative systems and in providing more solid theoretical foundations for the science of Human-Computer Interaction.Peer reviewedFinal Accepted Versio
On-farm biosecurity in livestock production: farmer behaviour, cultural identities and practices of care
This is the author accepted manuscript. The final version is available from Portland Press via the DOI in this recordefinitions of biosecurity typically include generalised statements about how biosecurity risks on farms should be managed and contained. However, in reality, on-farm biosecurity practices are uneven and transfer differently between social groups, geographical scales and agricultural commodity chains. This paper reviews social science studies that examine on-farm biosecurity for animal health. We first review behavioural and psychosocial models of individual farmer behaviour/decisions. Behavioural approaches are prominent in biosecurity policy but have limitations because of a focus on individual farmer behaviour and intentions. We then review geographical and rural sociological work that emphasises social and cultural structures, contexts and norms that guide disease behaviour. Socio-cultural approaches have the capacity to extend the more commonly applied behavioural approaches and contribute to the better formulation of biosecurity policy and on-farm practice. This includes strengthening our understanding of ‘good farming' identity, tacit knowledge, farmer influence networks, and reformulating biosecurity as localised practices of care. Recognising on-farm biosecurity as practices of biosecure farming care offers a new way of engaging, motivating and encouraging farmers to manage and contain diseases on farm. This is critical given government intentions to devolve biosecurity governance to the farming industry

Expanding the neurological phenotype of ring chromosome 10 syndrome: A case report and review of the literature
Ring chromosome 10 [r(10)] syndrome is a rare genetic condition, currently described in the medical literature in a small number of case report studies. Typical clinical features include microcephaly, short stature, facial dysmorphisms, ophthalmologic abnormalities and genitourinary malformations. We report a novel case of r(10) syndrome and review the neurological and neuro-radiological phenotypes of the previously described cases. Our patient, a 3 year old Italian girl, represents the 20th case of r(10) syndrome described to date. Intellectual disability/developmental delay (ID/DD), microcephaly, strabismus, hypotonia, stereotyped/aggressive behaviors and elec-troencephalographic abnormalities were identified in our patient, and in a series of previous cases. A brain MRI disclosed a complex malformation involving both the vermis and cerebellar hemispheres; in the literature, posterior cranial fossa abnormalities were documented by CT scan in another case. Two genes deleted in our case (ZMYND11 in 10p and EBF3 in 10q) are involved in autosomal dominant neurodevelopmental disorders, characterized by different expressions of brain and posterior cranial fossa abnormalities, ID/DD, hypotonia and behavioral problems. Our case expands the neurological and neuroradiological phenotype of r(10) syndrome. Although r(10) syndrome represents an extremely rare condition, with a clinical characterization limited to case reports, the recurrence of specific neurological and neuroradiological features suggests the need for specific genotype-phenotype studies
