Surviving Supergentrification in Inner City Sydney: Adaptive Spaces and Makeshift Economies of Cultural Production

Artists and creative workers have long been recognized as playing an important role in gentrification, being often portrayed as forerunners of urban change and displacement in former industrial and working-class suburbs of ‘post-Fordist’ cities. However, as is well represented by recent research, the relationship between the arts, gentrification and displacement has been called into question. The purpose of this article, which draws on 30 case studies of creative spaces in Sydney's inner suburbs, is to chart some of the strategies of spatial adaptation and makeshift economies of solidarity that cultural workers adopt in order to keep living and working in areas of ‘supergentrification’. We document how cultural infrastructure is transformed by the gentrification process and argue that these alterations are critical to the survival of arts and culture in the city. Such makeshift economies contribute, in a practical way, to preserving the diversity that gentrification is sometimes deemed to destroy or displace. While the survival of creative spaces is a much less researched phenomenon than other forms of resistance or displacement, we suggest that it has important consequences for both research and policy decisions around gentrification, infrastructural development and urban cultural economies

Microbial biofilm community structure and composition on the lithic substrates of Herculaneum Suburban Baths

In this work, we want to investigate the impact of different substrates and different environmental condition on the biofilm communities growing on plaster, marble, and mortar substrates inside the Herculaneum Suburban Baths. To do so, we measured environmental conditions and sampled biofilm communities along the walls of the baths and used culture-dependent and -independent molecular techniques (DGGE) to identify the species at each sampling sites. We used the species pool to infer structure and richness of communities within each site in each substrate, and confocal light scanning microscopy to assess the three-dimensional structure of the sampled biofilms. To gather further insights, we built a meta-community network and used its local realizations to analyze co-occurrence patterns of species. We found that light is a limiting factor in the baths environment, that moving along sites equals moving along an irradiation gradient, and that such gradient shapes the community structure, de facto separating a dark community, rich in Bacteria, Fungi and cyanobacteria, from two dim communities, rich in Chlorophyta. Almost all sites are dominated by photoautotrophs, with Fungi and Bacteria relegated to the role of rare species., and structural properties of biofilms are not consistent within the same substrate. We conclude that the Herculaneum suburban baths are an environment-shaped community, where one dark community (plaster) and one dim community (mortar) provides species to a “midway” community (marble)

Switchable Solvent Selective Extraction of Hydrophobic Antioxidants from Synechococcus bigranulatus

Hydrophobic molecules, in particular, carotenoids, have been directly extracted from Synechococcus bigranulatus ACUF680 by means of secondary amine switchable solvent N-ethylbutylamine (EBA) without any other pretreatment. EBA was able to extract hydrophobic molecules from both fresh and frozen biomass at the same extent of the conventional procedure (about 20% of dry biomass). In particular, selective extraction of a zeaxanthin-enriched fraction (green fraction, GF) and a β-carotene-enriched fraction (orange fraction, OF) was obtained. The ratio between zeaxanthin and β-carotene was 4.4 ± 1.5 for GF, 0.07 ± 0.06 for OF, and about 1 for conventional extraction. These fractions showed in vitro antioxidant activity (IC50 values of 0.056 ± 0.013 and 0.024 ± 0.008 mg mL-1 for GF and OF, respectively) and biocompatibility on immortalized cells. Moreover, OF and GF were able to protect cells from oxidative stress, both before and after thermal treatment. Results clearly indicate that EBA is a good candidate to specifically extract β-carotene and zeaxanthin from the wet biomass of S. bigranulatus without affecting their biological activity. Skipping energy-intensive operations to break the cells and using either fresh or frozen biomass may be the driving factors to use EBA switchable solvent on an industrial scale

Adding more fuel to the fire: an eye-tracking study of idiom processing by native and non-native speaker

Using eye-tracking, we investigate on-line processing of idioms in a biasing story context by native and non-native speakers of English. The stimuli are idioms used figuratively (at the end of the day – ‘eventually’), literally (at the end of the day – ‘in the evening’), and novel phrases (at the end of the war). Native speaker results indicate a processing advantage for idioms over novel phrases, as evidenced by fewer and shorter fixations. Further, no processing advantage is found for figurative idiom uses over literal ones in a full idiom analysis or in a recognition point analysis. Contrary to native speaker results, non-native findings suggest that L2 speakers process idioms at a similar speed to novel phrases. Further, figurative uses are processed more slowly than literal ones. Importantly, the recognition point analysis allows us to establish where non-natives slow down when processing the figurative meaning

Alien Domains Shaped the Modular Structure of Plant NLR Proteins

Plant innate immunity mostly relies on nucleotide-binding (NB) and leucine-rich repeat (LRR) intracellular receptors to detect pathogen-derived molecules and to induce defense responses. A multitaxa reconstruction of NB-domain associations allowed us to identify the first NB-LRR arrangement in the Chlorophyta division of the Viridiplantae. Our analysis points out that the basic NOD-like receptor (NLR) unit emerged in Chlorophytes by horizontal transfer and its diversification started from Toll/interleukin receptor-NB-LRR members. The operon-based genomic structure of Chromochloris zofingiensis NLR copies suggests a functional origin of NLR clusters. Moreover, the transmembrane signatures of NLR proteins in the unicellular alga C. zofingiensis support the hypothesis that the NLR-based immunity system of plants derives from a cell-surface surveillance system. Taken together, our findings suggest that NLRs originated in unicellular algae and may have a common origin with cell-surface LRR receptors

Extending the temporal context of ethnobotanical databases: the case study of the Campania region (southern Italy)

<p>Abstract</p> <p>Background</p> <p>Ethnobotanical studies generally describe the traditional knowledge of a territory according to a "hic et nunc" principle. The need of approaching this field also embedding historical data has been frequently acknowledged. With their long history of civilization some regions of the Mediterranean basin seem to be particularly suited for an historical approach to be adopted. Campania, a region of southern Italy, has been selected for a database implementation containing present and past information on plant uses.</p> <p>Methods</p> <p>A relational database has been built on the basis of information gathered from different historical sources, including diaries, travel accounts, and treatises on medicinal plants, written by explorers, botanists, physicians, who travelled in Campania during the last three centuries. Moreover, ethnobotanical uses described in historical herbal collections and in Ancient and Medieval texts from the Mediterranean Region have been included in the database.</p> <p>Results</p> <p>1672 different uses, ranging from medicinal, to alimentary, ceremonial, veterinary, have been recorded for 474 species listed in the data base. Information is not uniformly spread over the Campanian territory; Sannio being the most studied geographical area and Cilento the least one. About 50 plants have been continuously used in the last three centuries in the cure of the same affections. A comparison with the uses reported for the same species in Ancient treatises shows that the origin of present ethnomedicine from old learned medical doctrines needs a case-by-case confirmation.</p> <p>Conclusion</p> <p>The database is flexible enough to represent a useful tool for researchers who need to store and compare present and previous ethnobotanical uses from Mediterranean Countries.</p

Walking the walk: a phenomenological study of long distance walking

Evidence suggests that regular walking can elicit significant psychological benefits although little evidence exists concerning long distance walking. The purpose of this study was to provide detailed accounts of the experiences of long distance walkers. Phenomenological interviews were conducted with six long distance walkers. Data were transcribed verbatim before researchers independently analyzed the transcripts. Participants reported a cumulative effect with positive feelings increasing throughout the duration of the walk. Long distance walking elicited positive emotions, reduced the effects of life-stress, and promoted an increased sense of well-being and personal growth. Results are aligned to theories and concepts from positive psychology

Not just for romance: applications of speed dating in social work education

In this article we address how a contemporary adaptation of the \u27speed dating\u27 model was used for educational purposes with two cohorts of social work students. We outline the dimensions of \u27speed dating\u27 as a contemporary social phenomenon, then address how this model relates specifically to groupwork process, and can be used to facilitate social work student learning. The curriculum for two classroom group activities using the \u27speed dating\u27 model are outlined, the first to develop university level study skills, the second for debriefing field placement learning experiences. Finally we examine why the \u27speed dating\u27 metaphor was successful in provoking a playful yet constructively creative space for students to engage in groupwork process.<br /

Gamer Girls: Navigating a Subculture of Gender Inequality

Purpose Video gaming, which remains culturally embedded in masculine ideals, is increasingly becoming a leisure activity for female consumers. Guided by social dominance theory, this paper examines how female gamers navigate the masculine-oriented gaming consumption context. Methodology/approach Eight avid female gamers (ages 20–29) participated in-depth interviews, following a phenomenological approach to better understand their lived experiences with video gaming. Data were analyzed using phenomenological procedures. Findings Findings reveal an undercurrent of gender-based consumer vulnerability, driven by stereotypical perceptions of “gamer girls” in the masculine-oriented gaming subculture. Further, the findings highlight the multilayered, multidimensional nature of gaming as a vulnerable consumption environment, at individual, marketplace, and cultural levels. Social implications The culturally embedded gamer girl stereotype provides a foundation upon which characteristics of consumer vulnerability flourish, including a culture of gender-based consumer harassment, systematic disempowerment in the marketplace, and conflicting actions and attitudes toward future cultural change. Originality/value This research suggests female gamers struggle to gain a foothold in gaming due to the socially and culturally constructed masculine dominance of the field. Our research study provides a stepping-stone for future scholars to explore gendered subcultures and begins to address the dynamic interplay of power, gender, technology, and the market
