The Aranda’s Pepa

"The German missionary Carl Strehlow (1871-1922) had a deep ethnographic interest in Aboriginal Australian cosmology and social life which he documented in his 7 volume work Die Aranda- und Loritja-Stämme in Zentral-Australien that remains unpublished in English. In 1913, Marcel Mauss called his collection of sacred songs and myths, an Australian Rig Veda. This immensely rich corpus, based on a lifetime on the central Australian frontier, is barely known in the English-speaking world and is the last great body of early Australian ethnography that has not yet been built into the world of Australian anthropology and its intellectual history. The German psychological and hermeneutic traditions of anthropology that developed outside of a British-Australian intellectual world were alternatives to 19th century British scientism. The intellectual roots of early German anthropology reached back to Johann Gottfried Herder (1744-1803), the founder of German historical particularism, who rejected the concept of race as well as the French dogma of the uniform development of civilisation. Instead he recognised unique sets of values transmitted through history and maintained that cultures had to be viewed in terms of their own development and purpose. Thus, humanity was made up of a great diversity of ways of life, language being one of its main manifestations. It is this tradition that led to a concept of cultures in the plural.

Cultural Evolution and Perpetuation of Arbitrary Communicative Conventions in Experimental Microsocieties

Previous studies have shown that iconic graphical signs can evolve into symbols through repeated usage within dyads and interacting communities. Here we investigate the evolution of graphical signs over chains of participants. In these chains (or "replacement microsocieties"), membership of an interacting group changed repeatedly such that the most experienced members were continually replaced by naive participants. Signs rapidly became symbolic, such that they were mutually incomprehensible across experienced members of different chains, and new entrants needed to learn conventionalised meanings. An objective measure of graphical complexity (perimetric complexity) showed that the signs used within the microsocieties were becoming progressively simplified over successive usage. This is the first study to show that the signs that evolve in graphical communication experiments can be transmitted to, and spontaneously adopted by, naive participants. This provides critical support for the view that human communicative symbols could have evolved culturally from iconic representations

Predictors of Bank Distress : The 1907 Crisis in Sweden

This paper contributes to literature on bank distress using the Swedish experience of the in- ternational crisis of 1907, often paralleled with 2008. By employing previously unanalyzed bank-level data, we use logit regressions and principal component analysis to measure the im- pact of pre-crisis bank characteristics on the probability of their subsequent distress. The crisis was characterized by “creative destruction,” as those banks with weaker corporate governance structures, wider branching networks, operating with lower cost efficiency were more likely to experience distress. We find that poor credit allocation rather than foreign borrowing, as often stressed, were associated with ultimate demise

Cell Atlas technologies and insights into tissue architecture.

Since Robert Hooke first described the existence of 'cells' in 1665, scientists have sought to identify and further characterise these fundamental units of life. While our understanding of cell location, morphology and function has expanded greatly; our understanding of cell types and states at the molecular level, and how these function within tissue architecture, is still limited. A greater understanding of our cells could revolutionise basic biology and medicine. Atlasing initiatives like the Human Cell Atlas aim to identify all cell types at the molecular level, including their physical locations, and to make this reference data openly available to the scientific community. This is made possible by a recent technology revolution: both in single-cell molecular profiling, particularly single-cell RNA sequencing, and in spatially resolved methods for assessing gene and protein expression. Here, we review available and upcoming atlasing technologies, the biological insights gained to date and the promise of this field for the future

The effects of textured insoles on quiet standing balance in four stance types with and without vision

Background: Wearing a textured shoe insole can decrease postural sway during static balance. Previous studies assessed bipedal and/or unipedal standing. In contrast, we aimed to investigate if textured insoles modulated postural sway during four stance types (bipedal, standard Romberg, tandem Romberg, and unipedal), with and without vision.Methods: The repeated measures design involved 28 healthy young adults (13 females; mean age = 26.86 +/- 6.6 yrs) performing quiet standing in the four stance types on a force platform, under two different insole conditions (textured insole; TI vs. smooth insole; SI), with eyes open and eyes closed. Postural sway was assessed via the range and standard deviation of the COP excursions in the anterior-posterior and medial-lateral sway, and overall mean velocity.Results: The main effect of insole type was statistically significant at the alpha p = 0.05 level (p = 0.045). Compared to smooth insoles, textured insoles reduced the standard deviation of anterior-posterior excursions (APSD). While simple main effect analyses revealed this was most pronounced during eyes closed bipedal standing, insole type did not provide a statistically significant interaction with either stance or vision in this measure, or any other. Postural sway showed statistically significant increases across both stance type (bipedal < standard Romberg < tandem Romberg < unipedal), and vision (eyes closed < eyes open), in almost all measures. Stance and vision did have a statistically significant interaction in each measure, reflecting greater postural disturbances with eyes closed when stance stability decreased.Conclusions: Overall, these results support textured insole use in healthy young adults to reduce postural sway measures. This is because APSD is an index of spatial variability, where a decrease is associated with improved balance and possibly translates to reduced falls risk. Placing a novel texture in the shoe presumably modulated somatosensory inputs. It is important to understand the underlying mechanisms by which textured insoles influence postural sway. As such, utilising a healthy adult group allows us to investigate possible mechanisms of textured insoles. Future research could investigate the potential underlying mechanisms of textured insole effects at a neuromuscular and cortical level, in healthy young adults

Enticing Communication: An Examination of Environmental Arrangement Strategies in Early Intervention Settings

Many children develop language naturally, but some children experience communication delays. In these cases, naturalistic communication intervention can improve a child’s language abilities. One component of naturalistic communication intervention and the focus of this study is environmental arrangement (EA). This study sought to understand the relationship between parent-implemented EA strategy use during daily home routines and child rate of communication. Thirteen sets of video recordings were transcribed and coded from a larger data set from the Language and Play Every Day program (LAPE) to be analyzed. Although there appeared to be a relationship when looking at the averages, no statistically significant correlations between EA usage and child rate of communication were found

Evaluation of benthic assemblage structure in the NAFO regulatory area with regard to the protection of VME

This article presents the results from the analysis of data acquired during the NEREIDA survey programme (2009-2010) around the Flemish Cap and the tail of the Grand Banks of Newfoundland (NAFO Regulatory Area). Biological samples were collected using a mega box-core, which were processed for the extraction and identification of benthic macrofauna. A suite of physical samples and environmental measurements was also collected for evaluation. Analyses revealed the presence of benthic assemblages that were indicative of Vulnerable Marine Ecosystems (VME). VME indicative assemblages were present mostly outside of the fishing footprint. A simple habitat suitability model identified areas that are likely to accommodate VME indicative assemblages. Areas with the greatest potential to accommodate VME assemblages closely correspond with areas already managed for the protection of VME, where bottom-contact fishing practices are presently excluded. Such results support the notion that existing bottom-fishery exclusion zones should continue to be enforced for the long-term protection of VME.En prensa2,277

Reconstructing baselines: use of habitat suitability modelling to predict pre-fishing condition of a Vulnerable Marine Ecosystem

As industrialized fishing activities have moved into deeper water, the recognition of Vulnerable Marine Ecosystems (VMEs) has become important for the protection of the deep-sea. Our limited knowledge on the past and present distribution of VMEs hinders our ability to manage bottom fisheries effectively. This study investigated whether accounting for bottom fishing intensity (derived from Vessel Monitoring System records) as a predictor in habitat suitability models can (1) improve predictions of, and (2) provide estimates for a pre-fishing baseline for the distribution and biomass of a VME indicator taxon. Random Forest models were applied to presence/absence and biomass of Geodia sponges and environmental variables with and without bottom fishing intensity. The models including fishing were further used to predict distribution and biomass of Geodia to a pre-fishing scenario. Inclusion of fishing pressure as a predictive term significantly improved model performance for both sponge presence and biomass. This study has demonstrated a way to produce a more accurate picture of the current distribution of VMEs in the study area. The pre-fishing scenario predictions also identified areas of suitable Geodia habitat that are currently impacted by fishing, suggesting that sponge habitat and biomass have been impacted by bottom trawling activities.1054-3139Versión del editor2,27
