    Environmental and Sustainability Indicators 11: 100131
    Cities face growing challenges and urban greenspaces (UGS) play a key role in improving cities liveability. UGS are complex socio-ecological systems and evidence-based and context-sensitive tools are needed to assist planning and manage environmentally sound and socially inclusive UGS. In this paper, we propose an innovative indicator-based tool to operationalize the biocultural diversity (BCD) framework in urban contexts, deriving from its three conceptual layers – materialized, lived and stewardship. Indicators proposed are bundled in themes representing essential components when assessing and analyzing urban BCD from a contextual and sensitizing perspective. The set of indicators highlight key features of socio-cultural and ecological systems, theirs links and interactions, both material and non-material, to capture the essence of biocultural diversity at site-level. By offering a uniform scoring system with the possibility to set site-specific benchmarks, these can be used in any type of greenspace of any city, while allowing different communities/neighborhoods/city councils to embrace different approaches to meet their objectives towards larger scale goals. Twelve urban parks in Lisbon were used as a test-bed for the indicator-based tool and proved its feasibility to gather an overall snapshot of all parks and to demonstrate the possibility to deepen the study to only two parks uncovering self-exclusion processes that otherwise would have remained hidden. The BCD tool brings together essential information scattered over several quality and good practices assessment tools and protocols and, by including indicators specifically addressing governance and stewardship, offers a policy-driven instrument able to capture trade-offs and/or synergies between ecological, social and political domains.

    Puumala virus (PUUV) is the agent of nephropathia epidemica (NE), a mild form of hemorrhagic fever with renal syndrome (HFRS) in Europe. NE incidence presents a high spatial variation throughout France, while the geographical distribution of the wild reservoir of PUUV, the bank vole, is rather continuous. A missing piece of the puzzle is the current distribution and the genetic variation of PUUV in France, which has been overlooked until now and remains poorly understood. During a population survey, from 2008 to 2011, bank voles were trapped in eight different forests of France located in areas known to be endemic for NE or in area from where no NE case has been reported until now. Bank voles were tested for immunoglobulin (Ig)G ELISA serology and two seropositive animals for each of three different areas (Ardennes, Jura and Orleans) were then subjected to laboratory analyses in order to sequence the whole S, M and L segments of PUUV. Phylogenetic analyses revealed that French PUUV isolates globally belong to the central European (CE) lineage although isolates from Ardennes are clearly distinct from those in Jura and Orleans, suggesting a different evolutionary history and origin of PUUV introduction in France. Sequence analyses revealed specific amino acid signatures along the N protein, including in PUUV from the Orleans region from where NE in humans has never been reported. The relevance of these mutations in term of pathophysiology is discussed.

    Working Papers
    This paper discusses various theoretical approaches to diversity management, analysing their similarities and differences. I start with a review of certain previously presented classifications, and then proceed to describing the different approaches in more detail. In this paper, I propose that the various viewpoints can be categorized into three groups: 1) practitioner/consultant approach, 2) mainstream approach, and 3) critical approaches. Although there are differences within these groups, in particular regarding the critical approaches, these differences appear less significant than those between the groups. Those representing the first group are mainly interested in how to get most out of a diverse workforce, while those in the second group focus on the effects of diversity on performance or work group functioning. While some of the mainstream writers can be rather critical towards earlier research, they hardly ever discuss or even recognize the wide ranging criticism put forward by critical scholars. The critical researchers, then, remain a rather scattered group who do not always share much more than a conviction that the mainstream research keeps missing highly significant issues. Nonetheless, in order to increase our understanding of how different persons can and do work together, more dialogue is required between the varying standpoints.

    Avhandlingen består av en diskursanalys av intervjuer med kvinnoidentifierade personer verksamma inom startupekosystemet i Finland. Syftet med avhandlingen är att utforska kvinnornas tolkningar av startupekosystemets kultur från ett jämställdhets- och mångfaldsperspektiv. Avhandlingen bidrar med ett kritiskt perspektiv på startupkulturer och ämnar inspirera till nya synvinklar på sociologisk forskning om startupekosystem. De huvudsakliga forskningsfrågorna lyder: ”Hur förstår och tolkar kvinnor verksamma inom det finska startupekosystemet startupkulturen?”, ”Hur tolkar kvinnorna entreprenörsfiguren i rollen av det ideala startupsubjektet?” och ”Hur upplever kvinnorna jämställdhets- och mångfaldsdiskurser inom kontexten av det finska startupekosystemet?”. Det empiriska materialet består av kvalitativa semistrukturerade intervjuer med fyra kvinnor som på ett eller annat sätt är verksamma inom det finska startupekosystemet. Intervjuerna analyseras genom diskursanalys. Det teoretiska ramverket för avhandlingen består av synen på startupekosystem som performativa diskurser – diskurser som konstruerar de verkligheter de beskriver – och entreprenören som en performativ figur och det ideala startupsubjektet. Det teoretiska ramverket betonar vikten av att inkludera ekosystemet som en forskningsparameter i kulturell forskning om startupkulturer. Avhandlingen hämtar inspiration från akademiska diskussioner om den diskursiva konstruktionen av startup, entreprenörskap och teknologifältet. I avhandlingen framhävs i enlighet med forskning tre diskursiva teman som beskriver startupkulturen: öppenhet och hierarkilöshet; passion och heroism; samt rationalitet och hårt arbete. Samtliga diskursiva teman bidrar till en hegemonisk förståelse om startupkulturen som inkluderande, jämlik och rättvis. Avhandlingen ifrågasätter dessa premisser och argumenterar för att startupdiskurser bidrar till att reproducera en förgivettagen sanning om inkludering och jämlikhet som osynliggör maktstrukturer och förhindrar att status quo ifrågasätts. Dessa diskursiva formationer konstruerar entreprenörsfiguren, som representerar ett demokratiserat och jämlikt ideal inom en objektiv marknadsekonomi. Analysen påvisar att entreprenören, trots sina neutrala premisser, är könad och rasifierad, och lättare fäster sig vid maskulint kodade kroppar. Slutligen påvisar avhandlingen att respondenterna blivit marginaliserade som kunskapsinnehavare när det gäller frågor om jämställdhet och likabehandling. Avhandlingen föreslår att startupdiskurser och konstruktionen av entreprenörsfiguren påverkar hur jämställdhet och mångfald förstås inom fältet och skapar en förutsättning för icke-performativa diskurser och tystnader gällande jämställdhet och mångfald.

    The National Ecological Observatory Network (NEON) will monitor ground beetle populations across a network of broadly distributed sites because beetles are prevalent in food webs, are sensitive to abiotic factors, and have an established role as indicator species of habitat and climatic shifts. We describe the design of ground beetle population sampling in the context of NEON's long-term, continentalscale monitoring program, emphasizing the sampling design, priorities, and collection methods. Freely available NEON ground beetle data and associated field and laboratory samples will increase scientific understanding of how biological communities are responding to land-use and climate change.

    Aim Global biodiversity loss has raised interest in understanding variation in diversity at different scales. In particular, studies conducted across large spatial gradients are crucial, because they can increase perspectives on how ecological patterns change relative to environmental factors and facilitate predictions of possible responses to environmental change. We explored the full extent of a brackish sea to test the hypotheses that: (a) benthic communities are defined by the limited ranges of species, controlled by varying drivers along a large environmental gradient; (b) the responses of taxonomic and functional community composition and turnover to the environmental gradient are different, thus highlighting the need to include both measures in ecological studies; and (c) diversity reaches the minimum at intermediate salinities (Remane curve) owing to the low adaptation of freshwater and marine species. Location A large environmental and spatial gradient spanning the entire Swedish coastline (c. 2,300 km; salinity 1.2-27.6), the Baltic Sea. Time period August 2018. Major taxa studied Benthic diatoms. Methods We assessed environmental drivers for the communities and calculated the taxonomic and functional alpha and beta diversity along the gradient. We also compared the taxonomic and functional composition and diversity of communities among areas with different salinity. Results We found support for the hypothesis of limited species ranges, because taxonomic beta diversity, mainly induced by changes in salinity and climate, was high, whereas functional beta diversity remained considerably lower, and the composition and diversity of communities, in addition to environmental drivers controlling the communities, differed between regions with different salinity. The lowest taxonomic diversity was found at intermediate salinities of 5-6. Main conclusions These findings advance understanding of large-scale patterns of benthic diversity, emphasize the importance of large gradient studies for a better understanding of general ecological patterns and highlight the vulnerability of brackish water ecosystems as ecologically important tipping-point realms.

    In many countries diversity management has become an increasingly common way of treating differences between people in the world of work. Companies may sign diversity charters to show their engagement in promoting diversity, design and implement diversity management programmes, and communicate about their diversity initiatives to internal and external stakeholders. But what does diversity in the workplace mean? Who is defined as being different? And what do those defined as being different think about diversity and difference in work? By addressing these questions this book sheds light on the complex meanings of diversity management. The meanings of diversity management have long been developed and discussed in relation to equality and anti-discrimination policy and practice. A key question has been whether diversity management is a better way to enhance equality between organisational members or, on the contrary, is it diluting the results of equality approaches. The scope of this study is broader and shows that meanings of diversity management are constructed by drawing on not only knowledge about equality and anti-discrimination, but also understandings of society, the organisation, the individual, and the nature of differences. The study is informed by poststructuralist theory and based on interview data produced with 23 diversity managers and 52 ethnic minority employees in diversity promoting organisations in Finland and France. The findings contribute to the field of diversity management in several ways. First of all, the results show that there is no unitary meaning of diversity, difference and diversity management, but a number of discourses together forming the complexity and variety of what diversity management can come to mean in a given context and at a given point of time. Secondly, the findings challenge the idea that diversity management initiatives would be based solely on essentialist views of difference. However, the findings also show that even when differences are seen to be socially constructed, the organisation is not seen as participating in the construction of differences and in the production of related inequalities. Thirdly, the findings show that ethnic minority employees rarely draw on their differences as positive resources in work, and that they often are left alone to manage challenging situations related to difference, even in organisations promoting diversity. Lastly, the study highlights the importance of being attentive to national societal context, as discursively constructed, throughout the research process.

    Studying the evolution of viruses and their molecular epidemiology relies on accurate viral sequence data, so that small differences between similar viruses can be meaningfully interpreted. Despite its higher throughput and more detailed minority variant data, next-generation sequencing has yet to be widely adopted for HIV. The difficulty of accurately reconstructing the consensus sequence of a quasispecies from reads (short fragments of DNA) in the presence of large between-and within-host diversity, including frequent indels, may have presented a barrier. In particular, mapping (aligning) reads to a reference sequence leads to biased loss of information; this bias can distort epidemiological and evolutionary conclusions. De novo assembly avoids this bias by aligning the reads to themselves, producing a set of sequences called contigs. However contigs provide only a partial summary of the reads, misassembly may result in their having an incorrect structure, and no information is available at parts of the genome where contigs could not be assembled. To address these problems we developed the tool shiver to pre-process reads for quality and contamination, then map them to a reference tailored to the sample using corrected contigs supplemented with the user's choice of existing reference sequences. Run with two commands per sample, it can easily be used for large heterogeneous data sets. We used shiver to reconstruct the consensus sequence and minority variant information from paired-end short-read whole-genome data produced with the Illumina platform, for sixty-five existing publicly available samples and fifty new samples. We show the systematic superiority of mapping to shiver's constructed reference compared with mapping the same reads to the closest of 3,249 real references: median values of 13 bases called differently and more accurately, 0 bases called differently and less accurately, and 205 bases of missing sequence recovered. We also successfully applied shiver to whole-genome samples of Hepatitis C Virus and Respiratory Syncytial Virus. shiver is publicly available from https://github.com/ChrisHIV/shiver.

    Palaearctic grasslands encompass a diverse variety of habitats, many of high nature value and vulnerability. The main challenges are climate-change, land-use change, agricultural intensification and abandonment. Many measures are in place to address these challenges, through restoration and appropriate management, though more work is necessary. We present eight studies from China/Germany, Greece, Kazakhstan, Russia and Ukraine. The papers cover a wide range of grassland and steppe habitats and cover vegetation ecology, syntaxonomy and zoology. We also conducted a systematic search on steppe and grassland diversity. The greatest number of studies was from China, followed by Germany and England. We conclude that the amount of research being carried out on Eurasian grasslands is inadequate considering their high levels of biodiversity and vulnerability. We hope to encourage readers to address current major challenges, such as how to manage grasslands for the benefit of diverse taxa, to ensure that conservation initiatives concentrate on sites where there is good potential for success and for the generation of realistic and viable conservation strategies.

    Eutrophication is a major problem currently impacting many surface water ecosystems. Impacts of increased nutrient concentrations on biodiversity may differ between different scales, different organism groups, and different trophic states. Surveys at different spatial scales have suggested that biodiversity of different taxa may exhibit significant cross-taxon congruence. In our study, we examined the diversity of zooplankton and zoobenthos across 261 lakes in the Lake Taihu watershed, an area that is undergoing a severe eutrophication process. We tested the cross-taxon congruence in species richness and Shannon-Wiener diversity between zooplankton and zoobenthos along a nutrient gradient across the lakes. Our findings were consistent with the intermediate disturbance hypothesis, considering nutrient input as the disturbance. Also, we found significant cross-taxon congruence between zooplankton and zoobenthos diversities. Our results confirmed that excess nutrient levels resulted in diversity loss and community simplification. Zoobenthos were more sensitive to nutrient increases compared with zooplankton, which decreased cross-taxon congruence because these organism groups did not respond similarly to the anthropogenic disturbance.

    Fashion blogs are invention of the new millennia. Starting with something as simple as commenting on the outfit or a fashion event using this online medium, modern bloggers transformed it now into a successful business venture and a massive network for sharing ideas, tips and personal struggles with their followers. Thus, nowadays, a successful fashion blogger can be anything from a minor celebrity in the blogosphere, to a major international influencer in the fashion industry. Being personally fascinated by the way modern fashion bloggers run their blogs and manage to create a personal brand, I have decided to focus my research on creation of an online identity fashion bloggers go through whilst managing their personal blogs. Intentionally, or unintentionally personal fashion bloggers develop a certain type of writing and content creation that allows them to connect to many people. Fashion bloggers try to produce an idea that will guarantee them professional success. However, their personal background partially already set them up to be more connected to a certain group of people rather than the other. It is visible in their looks, ethnicity, lifestyle, personal interests and in opinions what type of people would be the majority of their followers. As a results, the network of followers that will be build by the blogger will determine what type of content she will be producing to attract even more readers. This is what will be discussed in this thesis: how fashion bloggers behave and what they primarily focus on in their blogs to keep up the online persona they are constructing.

    This article examines religion in Finnish newspapers, arguing that religion-related discourses have changed from one of Lutheran dominance to one of diversity. The main data consists of a longitudinal sample (1946-2016) of the most popular Finnish newspaper, Helsingin Sanomat, and especially of its editorials and readers' letters. Additional data covers a wider variety of newspapers from the 1990s to 2018. The data is analysed using quantitative content analysis and a discursive approach. It will be suggested that it is possible to discuss diversity both as an emergent discourse and a theme in the Finnish media since the mid-1990s, thereby overcoming earlier frameworks that took Lutheranism for granted or gave it a special role in the private sphere. The analysis shows that these shifts do not provide clear support for the idea that newspapers and journalism are anti-religious; rather, it suggests that they may be understood as having a 'liberalizing' effect, especially when religious values are not seen as compatible with those of journalists and newspapers.

    Background: Early-life indoor bacterial exposure is associated with the risk of asthma, but the roles of specific bacterial genera are poorly understood. Objective: We sought to determine whether individual bacterial genera in indoor microbiota predict the development of asthma. Methods: Dust samples from living rooms were collected at 2 months of age. The dust microbiota was characterized by using Illumina MiSeq sequencing amplicons of the bacterial 16S ribosomal RNA gene. Children (n = 373) were followed up for ever asthma until the age of 10.5 years. Results: Richness was inversely associated with asthma after adjustments (P = .03). The phylogenetic microbiota composition in asthmatics patients' homes was characteristically different from that in nonasthmatic subjects' homes (P = .02, weighted UniFrac, adjusted association, permutational multivariate analysis of variance, PERMANOVA-S). The first 2 axis scores of principal coordinate analysis of the weighted UniFrac distance matrix were inversely associated with asthma. Of 658 genera detected in the dust samples, the relative abundances of 41 genera correlated (r > vertical bar 0.4 vertical bar) with one of these axes. Lactococcus genus was a risk factor for asthma (adjusted odds ratio, 1.36 [95% CI, 1.13-1.63] per interquartile range change). The abundance of 12 bacterial genera (mostly from the Actinomycetales order) was associated with lower asthma risk (P <.10), although not independently of each other. The sum relative abundance of these 12 intercorrelated genera was significantly protective and explained the majority of the association of richness with less asthma. Conclusion: Our data confirm that phylogenetic differences in the microbiota of infants' homes are associated with subsequent asthma risk and suggest that communities of selected bacteria are more strongly linked to asthma protection than individual bacterial taxa or mere richness.

    The aim of the study is to examine primary school teachers’ opinions concerning a reformed model of the religious- and ethics education in the Finnish school context and how it can affect the students development of their own cultural identity and feeling of solidarity in schools. The study is based on the current discussions about the subject where globalization and diversity is seen to be demanding more of schools (Rautionmaa & Kallioniemi, 2017). Previous studies also show that the cultural segregation that is seen in the society is a result of the segregation done in schools (Korkeakoski & Ubani, 2018). A relatively new study done in Finland found out the Finnish populations view about a reformed model of these subjects and shows that the majority of the population advocate a reformation (Mattsonn, 2020). The research was conducted as a qualitative study with a phenomenographic research approach. The material consists of six semi-structured, individual interviews with teachers working in four different schools in the metropolitan area. The collected material was analyzed using content analysis. The results showed that the majority of the teachers, four out of six, found a reformed model of the subject as a positive development and that it would come to support every student. Some of the effects predicted were an increased understanding and solidarity between students with different cultural backgrounds, more equality that would lead to a more integrated society. Some of the aspects seen from the teachers who didn’t support a reformation was that education in faith is important, the possibility that one student may feel excluded and that an separate religious education would be important especially for those who belong to a minority religion.
  • Crosier, Brittni Joette (Helsingin yliopisto, 2020)
    Biogeography is a crucial aspect to ecological studies, as an ecosystem is comprised of the physical habitat, the organisms living there, and the interactions of these components. Community structure, and therefore functioning, are inherently of a spatial nature. Spatial structure of populations is often crucial basic knowledge for understanding the evolutionary history, dispersal patterns, and resilience of any given species. One aspect of spatial structure, and the topic covered in this study, is community distance decay, or the rate at which community similarity decreases with physical distance. More of the landscape is constantly being altered by humans on a large scale, so it is increasingly important to understand the effects that these anthroprogenic changes to the environment has on local populations. Studying community distance decay helps form understanding of dispersal and establishment limitations for different organisms, which is necessary for mitigating biodiversity loss. Many studies show that habitat fragmentation and loss has greatly impacted the structure of plant and animal communities, but there has been much less focus on fungal communities. There’s no certainty that fungi is impacted in the same ways, given the different lifestyles and dispersal methods, so the aim of this study is to contribute to the much needed research on fungal community structure at various scales. This aim is addressed by examining fungal community distance decay from small scale of a couple kilometers or less to a fairly large scale encompassing a landscape of primarily urban, forest, and agricultural areas. The five main localities of sampling were in middle and southern Finland: Helsinki, Lahti, Tampere, Jyväskylä, and Joensuu. Sampling locations and plot design were chosen to allow the comparison of communities separated by a mosaic, as well as along a short rural to urban gradient, to assess the effects of habitat type. From each location, six plots were decided, two in urban core, one in urban edge, two in natural core, and one in natural edge. The role of dispersal ability and functional traits in distance decay is also studied by comparing results from two different methods of fungi sampling, which were collecting spores from the air using cyclone samplers, and taking soil cores to gather fungal biomass. All samples were DNA analysed with high-throughput sequencing and the results from the DNA barcoding were used to create OTU clusters, by which the 30 plots could be compared through relative abundances of OTU’s. I determined the similarity of fungal communities using an analysis of similarity (ANOSIM) test in R, where all possible variables (site, habitat type, sample type) were used as a grouping in individual tests, thereby indicating which variable is associated with highest community difference. I also determined the differences in functional groups and major taxonomic levels among locations and sampling method using interactive taxanomic (KRONA) charts. Results showed that there are differences in fungal community structure among habitat type and sampling type. However there was greater difference at the level of plots than site locations, so clear patterns of strong community distance decay with physical distance was not measured in this study. The results suggest that fungal communities can be fairly impacted by human caused habitat change, and individual characteristics, such as dispersal methods or lifestyle, effect the rate of community distance-decay. This provides a valuable early insight into fungal community patterns, which need deeper study to understand the complexities and mechanisms behind them.

    Sedimentary pollen offers excellent opportunities to reconstruct vegetation changes over past millennia. Number of different pollen taxa or pollen richness is used to characterise past plant richness. To improve the interpretation of sedimentary pollen richness, it is essential to understand the relationship between pollen and plant richness in contemporary landscapes. This study presents a regional-scale comparison of pollen and plant richness from northern Europe and evaluates the importance of environmental variables on pollen and plant richness. We use a pollen dataset of 511 lake-surface pollen samples ranging through temperate, boreal and tundra biomes. To characterise plant diversity, we use a dataset formulated from the two largest plant atlases available in Europe. We compare pollen and plant richness estimates in different groups of taxa (wind-pollinated vs. non-wind-pollinated, trees and shrubs vs. herbs and grasses) and test their relationships with climate and landscape variables. Pollen richness is significantly positively correlated with plant richness (r = 0.53). The pollen plant richness correlation improves (r = 0.63) when high pollen producers are downweighted prior to estimating richness minimising the influence of pollen production on the pollen richness estimate. This suggests that methods accommodating pollen-production differences in richness estimates deserve further attention and should become more widely used in Quaternary pollen diversity studies. The highest correlations are found between pollen and plant richness of trees and shrubs (r = 0.83) and of wind-pollinated taxa (r = 0.75) suggesting that these are the best measures of broad-scale plant richness over several thousands of square kilometres. Mean annual temperature is the strongest predictor of both pollen and plant richness. Landscape openness is positively associated with pollen richness but not with plant richness. Pollen richness values from extremely open and/or cold areas where pollen production is low should be interpreted with caution because low local pollen production increases the proportion of extra-regional pollen. Synthesis. Our results confirm that pollen data can provide insights into past plant richness changes in northern Europe, and with careful consideration of pollen-production differences and spatial scale represented, pollen data make it possible to investigate vegetation diversity trends over long time-scales and under changing climatic and habitat conditions.

    The traditional nuclear family is the most common type of family in our society. During the last decades other kinds of family models have appeared besides the nuclear family. Every child comes across with the diversity of families at some part of their lives. It will happen during their lives or when they start the early childhood education and school. Children should know how to meet the diversity and grow to understand it so that everyone would feel themselves appreciated. Children's books can be a tool to handle diversity of families with children. Through children's books, a child can observe different kinds of families and their lives from a reasonable distance. From a book, the child can find objects to identify to. The child also learns to understand his/her own family as well as other kinds of families. All this widens up the child's picture of the world and teaches how to tolerate dissimilarity. The goal of this research was to find out what kind of families can be found from the popular children's book series Risto Räppääjä, and how the families are represented in it. Another goal was to reflect how educators could use the series in preschool and in elementary school while discussing about diversity of families. The research also tries to broaden the impressions of parents and other educators towards how children's literature can be used variedly when teaching children liberality and how to be a member of the society who accepts dissimilarity. This research was qualitative. The research method was content analysis, where fictional documents were analyzed. The documents were 13 books from a children's book series Risto Räppääjä. Many kinds of families were found from the children's book series Risto Räppääjä. The extended family Räppääjä and nuclear family Perhonen were the most relevant families in this research. These two families broke many of the stereotypes that are placed towards families. Children's points of view and thoughts about families in general also surface from these two families. An adult reader and a child reader find opportunities to reflect the families to their own lives and consider their attitudes through these two families. Also through all the families in the series reader will learn different kinds of ways of living. The children's book series Risto Räppääjä can be used in many ways in preschool and elementary school, for example in conversations, drama and artwork.

    This thesis is the written component of artistic-pedagogical event Patella-floating bone that was created in collaboration with Theatre Pedagogy peer Elina Sarno, and performed over a four-night season in the Spring of 2018 at the Theatre Academy of Helsinki. My research is an enquiry into the relational in-between spaces of a diverse artistic working group with dance and theatre practices as the frame for sensory exploration and making. Disability and difference as diverse embodied perceptions come to interrelate in a co-creative, process-oriented and practice-based mode of making, within a landscape of nonhuman material things as equal agents in opening other relational spaces and embodiments to sense with. The research examines the phenomena in and of the process, how artistic practice and the ecology of interdependence emerge, interweave and inform creative art pedagogy in action. The work studies the performative experience of practice and audience experiences within a cohabited immersive setting. The main question that mobilised this research is: how does interrelational sensing occur between divers embodied perceptions and mobilise processes of art making and learning? The work suggests that through artistic practice which privileges embodied sensory exploration in the context of diversity and the call of materiality, the in-between spaces become foregrounded as fields of events unfolding, arising phenomena and knowledge-making. The group’s diversity of embodied perceptual differences informs and develops artistic enquiry through engaging in practice, co-creation and performance, harnessing pedagogical value in the very seeds of process. The group ecology of the shared in-between spaces becomes the generator for these relational experiences in the making. The research in the thesis engages philosophical and artistic theories with particular reference to Erin Manning’s understanding of agencement, and to disability discourse in dance by Ann Cooper Albright, to reflect and critique broader societal frames of dominant structures. Dialogical pedagogy theories and self-reflective research, as pedagogue and facilitator of emerging unknowns within the group ecology, move through a phenomenological landscape of knowledge-making processes. The performance outcome becomes a motor of playful exploration, yet in itself not an outcome but a practice in process within a cohabited shared space, in which audience are invited to participate through sensory perceptual ways to the in-betweenness of the diverse group embodiment, dissolving nonhuman / human dichotomies along with ableist dichotomies. I intend a mode of facilitation that opens to collaboration, that surrenders the pedagogy to a group artistic agent and to an immanent directionality in art, while honouring the role.
