Cultural diplomacy and internationalism in regional art institutions

This study posits that current cultural diplomacy practice in UK museums and galleries could be significantly improved. Indeed, cultural diplomacy is commonly viewed as nationalist propaganda. An attempt to theoretically debunk this proposition indicates that greater understanding between peoples can be engendered by unifying the ideologies of internationalism and liberalism in the cultural sector. Liberalism is viewed as the present ideology operating in Museums and Galleries whilst internationalism is considered as a nascent force. Working in symbiosis, liberalism allows for a multiplicity of discourse whilst internationalism allows for a critical reappraisal of the status quo and nation-state hegemony. Indeed, a multiplicity of dialogic discourse is essential for cultural institutions to maintain a non-hegemonic stance. This is, of course, particularly apparent in contemporary art work which can often be subversive of national governments and the very idea of a nation-state. Further to this, a form of localised cultural diplomacy can reach the public at large and question the cultural capital of world centres. Empirically speaking, the exhibition format is used as a means to render cultural diplomacy palatable for public consumption. Hence, the UK case study Art from Elsewhere will be introduced which has rendered the international a normative presence in local art galleries. This 2014–2016 exhibition comprised a tour of recent contemporary art acquisitions in regional permanent collections which were funded by a £5 million pound grant from the UK charitable organisation, Art Fund. Instead of monophonic exhibitions emanating from one nation, Art from Elsewhere engenders a multilateral dialogue catalysed by the polyphonic nature of artists from several different nations whose works are juxtaposed both in conflict, symmetry and contrast to one another.     

Constructing brain connectivity group graphs from EEG time series

Graphical analysis of complex brain networks is a fundamental area of modern neuroscience. Functional connectivity is important since many neurological and psychiatric disorders, including schizophrenia, are described as ‘dys-connectivity’ syndromes. Using electroencephalogram time series collected on each of a group of 15 individuals with a common medical diagnosis of positive syndrome schizophrenia we seek to build a single, representative, brain functional connectivity group graph. Disparity/distance measures between spectral matrices are identified and used to define the normalized graph Laplacian enabling clustering of the spectral matrices for detecting ‘outlying’ individuals. Two such individuals are identified. For each remaining individual, we derive a test for each edge in the connectivity graph based on average estimated partial coherence over frequencies, and associated p-values are found. For each edge these are used in a multiple hypothesis test across individuals and the proportion rejecting the hypothesis of no edge is used to construct a connectivity group graph. This study provides a framework for integrating results on multiple individuals into a single overall connectivity structure.     

Close encounters of the stressful kind: Affective,physiological, and behavioral reactions to the experience of crowding

Ninety-six adults participated in a study of the joint effects of interpersonal density and an additional stressor. Experiential reports, psychophysiological indices, and task performance were assessed. Subjects seated either close together or far apart worked on a series of tasks while either expecting a stressful event or not expecting the stressful event. Perceptions of crowding were influenced only by interpersonal distance; those seated close together reported feeling more crowded than those seated far apart. However, if subjects were both crowded and expected a stressful event they reported feeling more stressed and evidenced psychophysiological signs of anxiety. Relevance of these results for an additive stress model is discussed but the model is rejected and an interactional model of crowding and stress effects is proposed. Evidence for processes of social comparison fear reduction was found in some crowded subjects.     

Creating places,relationships and education for refugee children in camps: Lessons learnt from the ‘The School of Peace’ educational model

This paper describes a unique model for building an afternoon school for refugee children sustained by volunteers and refugee teachers and based on humanistic intercultural values. The methodology is participatory including the whole school, from children to teachers to volunteers and managers. Central themes in the findings include a synergetic focus on creative placemaking, conflict negotiation and formal studies. This points to a theoretical connection between informal and formal studies. The findings teach us about the needs of refugee children. A methodological contribution is the use of arts-based methods to capture refugee children's lived experiences of school.     

Effects of Nurturing and Non‐nurturing Caregiving on Child Social Initiatives: An Experimental Investigation of Emotion as a Mediator of Social Behavior1

This study examined the effects of one unfamiliar adult's warm, responsive interactions or cold, aloof, unresponsive interactions on child emotion and subsequent social initiatives to a second adult. Participants were 32 4¹/₂‐ to 5¹/₂‐year‐old preschool children. Nurturing, responsive caregiving and non‐nurturing, unresponsive caregiving were experimentally manipulated by experimenter facial and vocal affective expressions, positive versus negative statements to the child, and contingency of responding to the child's behavior. The effect of nurturance was examined on child emotions and social initiatives to another adult. Non‐nurturing caregiving produced less expressed happiness and fewer subsequent social initiatives. Furthermore, child emotion was found to mediate partially the relation between nurturing caregiving and social initiatives, with children who experienced interactions with a non‐nurturing caregiver expressing less happiness, which led to decreased social initiatives to a second adult.     

Variance Estimators of the Gini Coefficient—Probability Sampling

An estimator of the Gini coefficient (the well-known income inequality measure) of a finite population is defined for an arbitrary probability sampling design, taking the sampling design into consideration. Alternative estimators of the variance of the estimated Gini coefficient are introduced. The sampling performance of the Gini coefficient estimator and its variance estimators is studied by means of a Monte Carlo study, using stratified sampling from a miniature population of Swedish households with authentic income data.     

Matching pursuit by undecimated discrete wavelet transform for non-stationary time series of arbitrary length

We describe how to formulate a matching pursuit algorithm which successively approximates a periodic non-stationary time series with orthogonal projections onto elements of a suitable dictionary. We discuss how to construct such dictionaries derived from the maximal overlap (undecimated) discrete wavelet transform (MODWT). Unlike the standard discrete wavelet transform (DWT), the MODWT is equivariant under circular shifts and may be computed for an arbitrary length time series, not necessarily a multiple of a power of 2. We point out that when using the MODWT and continuing past the level where the filters are wrapped, the norms of the dictionary elements may, depending on N, deviate from the required value of unity and require renormalization.We analyse a time series of subtidal sea levels from Crescent City, California. The matching pursuit shows in an iterative fashion how localized dictionary elements (scale and position) account for residual variation, and in particular emphasizes differences in construction for varying parts of the series.
