Emotion recognition in the human face and voice
This thesis was submitted for the award of Doctor of Philosophy and was awarded by Brunel University LondonAt a perceptual level, faces and voices consist of very different sensory inputs and therefore, information processing from one modality can be independent of information processing from another modality (Adolphs & Tranel, 1999). However, there may also be a shared neural emotion network that processes stimuli independent of modality (Peelen, Atkinson, & Vuilleumier, 2010) or emotions may be processed on a more abstract cognitive level, based on meaning rather than on perceptual signals. This thesis therefore aimed to examine emotion recognition across two separate modalities in a within-subject design, including a cognitive Chapter 1 with 45 British adults, a developmental Chapter 2 with 54 British children as well as a cross-cultural Chapter 3 with 98 German and British children, and 78 German and British adults. Intensity ratings as well as choice reaction times and correlations of confusion analyses of emotions across modalities were analysed throughout. Further, an ERP Chapter investigated the time-course of emotion recognition across two modalities. Highly correlated rating profiles of emotions in faces and voices were found which suggests a similarity in emotion recognition across modalities. Emotion recognition in primary-school children improved with age for both modalities although young children relied mainly on faces. British as well as German participants showed comparable patterns for rating basic emotions, but subtle differences were also noted and Germans perceived emotions as less intense than British. Overall, behavioural results reported in the present thesis are consistent with the idea of a general, more abstract level of emotion processing which may act independently of modality. This could be based, for example, on a shared emotion brain network or some more general, higher-level cognitive processes which are activated across a range of modalities. Although emotion recognition abilities are already evident during childhood, this thesis argued for a contribution of ‘nurture’ to emotion mechanisms as recognition was influenced by external factors such as development and culture.Economics and Social Research Counci
Decentralisation in times of crisis: asset or liability? The case of Germany and Italy during Covid-19
How did the legal and political-administrative relationship between central and local governments of two decentralised states shape their response to COVID-19? Literature and theories on decentralisation argue that federal and decentralised states are less able to respond to crises in a coordinated manner due to their perceived greater susceptibility to political conflict. Situated within this theoretical debate and based on the analysis of legal acts, political decisions, and relevant national news media articles between March and August 2020 in Germany and Italy, this research note shows that, counterintuitively, more decentralisation does not necessarily translate into more legal and political stress during pandemic management. In responding to the COVID-19 pandemic, Germany, a highly decentralised state, experienced less legal and political tensions than the less decentralised Italy. The key to understanding this variation lies in different institutional arrangements, complemented by the specific political cultures of both states
Scenario Planning with INKA 4: Electromobility in Germany
Vehicles powered by electricity are the future of mobility in Germany. At the present
time, electromobility is rather hesitantly implemented in Germany, particularly due to
concerns regarding charging infrastructure and battery power/technology.
The purpose of this research project is to forecast – by using scenario planning techniques - how electromobility will influence the way we move in Germany by 2035. The outcome are three distinct scenarios that reflect the possible shift towards E-Mobility in Germany, especially taking into consideration the charging infrastructure, different battery technology and type of electric vehicle. In order to generate scientifically significant scenarios, input factors (Descriptors) were designed in accordance with the newest research findings from literature. Additionally, special ratios between all possible manifestations of input factors were defined, compared and evaluated
Unternehmenskultur als Herausforderung der Post Merger Integration
Unternehmenszusammenschlüsse stellen insbesondere nach der Finanzkrise wieder eine interessante Wachstumsoption für Unternehmen dar. Da in einem Unternehmenszusammenschluss stets unterschiedliche Unternehmenskulturen aufeinanderprallen, führen damit einhergehende Veränderungen meist zu einem Verlust wichtiger Orientierungspunkte für die Mitarbeiter. Die Summe der Veränderungen resultiert in erheblichem Stress und Verunsicherung, die zu zusätzlichen Kosten führen und der angestrebten Realisierung von Synergien entgegenstehen.
Die Wissenschaft bietet der Praxis in diesem Bereich bislang wenig Hilfestellung. Es bestehen nur wenige Ansätze zur Integration der Unternehmenskultur, die im Akquisitionsprozess systematisch vorgehen; ferner fehlt es diesen meist an Methoden und Instrumenten zur praktischen Umsetzung.
Diese Arbeit zeigt in Form von konkreten Handlungsempfehlungen auf, wie ein Vorgehen in der Kulturintegration ausgestaltet werden kann. Als Grundlage dienen neben den bestehenden wissenschaftlichen Ansätzen zur Kulturintegration, Erkenntnisse aus der Untersuchung von zwei Unternehmenszusammenschlüssen in der Praxis. An diesen wurde deutlich, dass die Kulturintegration nicht erst in der Post Merger Phase des Akquisitionsprozesses vorgenommen werden sollte, sondern von Beginn an eine Rolle spielen muss. Ferner sind die aktive Einbindung von Mitarbeitern und eine durchgehende Kommunikation wesentlich für die erfolgreiche Integration der Unternehmenskultur. Entsprechende Erkenntnisse werden in den Handlungsempfehlungen berücksichtigt, die damit einen Orientierungsrahmen für das praktische Vorgehen in der Kulturintegration bilden
Effects of emotional study context on immediate and delayed recognition memory: Evidence from event-related potentials
Whilst research has largely focused on the recognition of emotional items, emotion may be a more subtle part of our surroundings and conveyed by context rather than by items. Using ERPs, we investigated which effects an arousing context during encoding may have for item-context binding and subsequent familiarity-based and recollection-based item-memory. It has been suggested that arousal could facilitate item-context bindings and by this enhance the contribution of recollection to subsequent memory judgements. Alternatively, arousal could shift attention onto central features of a scene and by this foster unitisation during encoding. This could boost the contribution of familiarity to remembering. Participants learnt neutral objects paired with ecologically highly valid emotional faces whose names later served as neutral cues during an immediate and delayed test phase. Participants identified objects faster when they had originally been studied together with emotional context faces. Items with both neutral and emotional context elicited an early frontal ERP old/new difference (200-400 ms). Neither the neurophysiological correlate for familiarity nor recollection were specific to emotionality. For the ERP correlate of recollection, we found an interaction between stimulus type and day, suggesting that this measure decreased to a larger extend on Day 2 compared with Day 1. However, we did not find direct evidence for delayed forgetting of items encoded in emotional contexts at Day 2. Emotion at encoding might make retrieval of items with emotional context more readily accessible, but we found no significant evidence that emotional context either facilitated familiarity-based or recollection-based item-memory after a delay of 24 h
Towards a standardization of soil-related ecosystem service assessments
The concept of ecosystem services (ES) creates understanding of the value of ecosystems for human well-being. With regard to soils, it provides a framework for assessments of soil contributions and soil management impacts. However, a lack of standardization impedes comparisons between assessment studies and the building of synthesis information. The Common International Classification of Ecosystem Services (CICES) is an important step forward, although its application to soils is not without difficulty. CICES version 5.1 defines 83 ES classes, of which only some are relevant for soils. We compiled two subsets of CICES classes: one set of soil-related ES comprising 29 services defined as directly and quantifiably controlled by soils and their properties, processes and functions, and another set of 40 ES defined as being affected by agricultural soil management. Additionally, we conducted a systematic literature review, searching for published lists of soil-related ES that claim completeness. We identified 11 relevant lists. Of all CICES classes, 12 were included in more than 75% of the lists, whereas another 36 classes were included in 25–75% of them. Regarding the suitability of the CICES classification for addressing ES in the context of soils and their agricultural management, we identified constraints, such as overlaps, gaps, and highly specific or very broad class definitions. Close cooperation between the soil research and ES communities could ensure better consideration of soils in future CICES updates. A shortlist of 25 service classes affected by agricultural soil management facilitates a standardized approach and may function as checklists in impact assessments
Britain avoids talking about COVID-19 deaths. that’s a mistake
How has the UK government acknowledged and talked about COVID-19 deaths? In an extract from their new report, Katharine M Millar, Yuna Han, Katharina Kuhn, Martin Bayly and Irene Morlino (LSE) warn that the current focus on ‘recovery’ and ‘inevitable’ deaths risks alienating sections of society, and suggest how it can do better. Pandemics present a ... Continue
Confronting the COVID-19 pandemic: grief, loss, and social order
This research addresses the challenge the 2019- 2020 COVID-19 pandemic (COVID-19) presents to social order as a result of mass grieving and loss. It places a particular emphasis on the UK response and lessons that can be learnt for further ‘waves’. A tendency for research to look at technocratic policy responses has led to the overlooking of the social impact that pandemics produce. This study, in contrast, employs a qualitative, comparative methodology to examine four key cases – the UK, Italy, South Korea, and Germany – from 1 January to 31 July 2020, as well as the UK during the 1918-19 influenza epidemic – to examine the politics of COVID-9 as a mass death event. Our research finds that the narrative framing of the pandemic as a particular type of crisis; the ways that deaths have been recorded and managed; and the manner in which loss has been mourned and commemorated vary across cases. This variance, the research suggests, has implications for the ways that societies may respond, particularly in the medium- and longterm. Recommendations are made for governments responding to future ‘waves’ of the virus in relation to communicating loss to the public, and commemorating deaths in a manner that supports social cohesion and prepares the public for future crises
