The PREDICTS database: a global database of how local terrestrial biodiversity responds to human impacts

Biodiversity continues to decline in the face of increasing anthropogenic pressures such as habitat destruction, exploitation, pollution and introduction of alien species. Existing global databases of species’ threat status or population time series are dominated by charismatic species. The collation of datasets with broad taxonomic and biogeographic extents, and that support computation of a range of biodiversity indicators, is necessary to enable better understanding of historical declines and to project – and avert – future declines. We describe and assess a new database of more than 1.6 million samples from 78 countries representing over 28,000 species, collated from existing spatial comparisons of local-scale biodiversity exposed to different intensities and types of anthropogenic pressures, from terrestrial sites around the world. The database contains measurements taken in 208 (of 814) ecoregions, 13 (of 14) biomes, 25 (of 35) biodiversity hotspots and 16 (of 17) megadiverse countries. The database contains more than 1% of the total number of all species described, and more than 1% of the described species within many taxonomic groups – including flowering plants, gymnosperms, birds, mammals, reptiles, amphibians, beetles, lepidopterans and hymenopterans. The dataset, which is still being added to, is therefore already considerably larger and more representative than those used by previous quantitative models of biodiversity trends and responses. The database is being assembled as part of the PREDICTS project (Projecting Responses of Ecological Diversity In Changing Terrestrial Systems – www.predicts.org.uk). We make site-level summary data available alongside this article. The full database will be publicly available in 2015.

Core and patch position optimizations for vibration control of piezolaminated structures

This paper deals with a finite formulation baserd on the classical laminated plate tehory, for active control of thin late laminated structures with integrated piezoelectric layers, acting as sensors and actuators. The control is initialized through a previuos optimization of the core of the laminated structure, in order to minimize the vibration amplitude. Also the optimization of the patches position in performed to maximize the piezoelectric actuator efficiency. the simulating annealing mthod is used for these purposes. The finite element model is a single layer triangular nonconforming plate/shell element with 18 degrees of fredom for the generalized displacements, and one electrical potential degree of freedom for each piezoelectric element layer, wich can be surface bonded or imbedded on the laminate. To achieve a mechanism of active control of the structure dynamic response, a feedback control algorirhm is used, coupling the sensor and active piezoelectric layers. To calculate the dynamic response of the laminated structures the Newmark method is considered. The model is applied in the solution of an illustrative case and the results are presented and discussed.

The SmartVision navigation prototype for the blind

The goal of the project "SmartVision: active vision for the blind" is to develop a small and portable but intelligent and reliable system for assisting the blind and visually impaired while navigating autonomously, both outdoor and indoor. In this paper we present an overview of the prototype, design issues, and its different modules which integrate a GIS with GPS, Wi-Fi, RFID tags and computer vision. The prototype addresses global navigation by following known landmarks, local navigation with path tracking and obstacle avoidance, and object recognition. The system does not replace the white cane, but extends it beyond its reach. The user-friendly interface consists of a 4-button hand-held box, a vibration actuator in the handle of the cane, and speech synthesis. A future version may also employ active RFID tags for marking navigation landmarks, and speech recognition may complement speech synthesis.

Conversations with remarkable teachers an exploration of teaching as healing

Through analysis and interpretation of transcribed taped conversations with two remarkable University teachers, Joel Shack and Harry Whittier, an articulation of perception and metaphor that exists in effective teaching, emerges as life giving or transformational. Creative insight and interpretation connect teaching to life. This work demonstrates how insightful conversations about teaching relate to poetic essence (Joel), energy (Harry), and healing (Ray), all aspects of a similar perceptual, creative and transformative process. Teachers shape education and excellent teaching inspires insofar as it is inspirited. Effective teaching is highly conscious and intentional. So much depends on how aware the teacher is, how the teacher sees what s/he is doing and how this doing/teaching is received. The effective teacher, attentive to how this energy works, can provoke positive change in consciousness both in the student, in education and in society. My study draws attention to the healing power of the teacher as he/she teaches and to the process of dialogue as teachers talk about what they do and don't do. For inherent in conversation and dialogue is the desire to affirm whole perceptions of existence. Dialogue and conversation is necessary to creating the kind of consciousness that will aid the reflective and conscientious teacher. The effective teacher attempts to effect change, to make things better. I call this transforming process, healing. And what creates this healing is the life, the attitude and approach of the teacher. The teacher's energy and consciousness, the teacher's perception of meaning, is the active but implicit ingredient in this transformative and healing process. These conversations are creative, theoretical, illuminating and even practical. It is my hope that the contents of these conversations will inspire potential teachers who can consider the vocation of teaching as a healing process that promises to generate positive growth in mind, body and spirit.

O repertório cerâmico da sala nº 1(Vidigueira), na sequência Neolítico final e Calcolítico do Alentejo Médio

O trabalho aqui proposto tem como objectivo central, a realização de análises ao conjunto dos recipientes cerâmicos pertencentes ao povoado da Sala nº1. Repertório esse, que se baseou no acervo retirado do sítio arqueológico Sala nº1, intervencionado pelo Professor Victor S. Gonçalves (1988, 1989 e 1995). As análises e descrições efectuadas foram sempre norteadas para a tentativa de estabelecer uma sequência de formas que se pudesse verificar quanto à sua normalização e frequência nos contextos presentes ao povoado da Sala nº1. Traduzindo nessa realidade, a diacronia transversal entre os estratos arqueológicos pertencentes ao Neolítico final e os estratos pertencentes ao Calcolítico. Tendo sempre como parâmetros de análise, as metodologias e critérios descritivos dos recipientes cerâmicos, presentes nos trabalhos publicados sobre as realidades cronológicas semelhantes no Sul de Portugal. O próprio conjunto de recipientes cerâmicos aqui analisado foi submetido a essas metodologias, com fim de obter primordialmente as formas e as tipologias a que pertencem. Nesse sentido procurei criar um quadro de referência local e regional, e posteriormente coloca-lo num enquadramento geral do Neolítico final e início do Calcolítico do Alentejo Médio, tentando verificar as similitudes nos quadros tipológicos existentes, como os estabelecidos por Carlos Tavares da Silva e Joaquina Soares. Sendo este um estudo que abrange um tempo cronológico de praticamente 1500 anos, premiei através da amplitude dos contornos que moldaram esta análise, algumas perspectivas possíveis. Quer ao nível das tipologias, quer ao nível das estratégias de ocupação do território, aplicáveis para o espaço e o tempo em análise. Verificando a realidade escassa nos contextos alentejanos (publicados), em que a cultura material se integra numa estratigrafia e cronologias com uma diacronia semelhante à do povoado da Sala nº1. Tentei integrar este povoado num estudo que não sendo comparativo, tivesse essa componente em relação às tipologias e formas cerâmicas identificadas. Procurou-se dar enfase à realidade artefactual das taças carenadas, e à sua possível evolução para formas mais adaptáveis ao uso e consumo quotidiano das comunidades contemporâneas das fases Calcolíticas do povoado.

Development of user-friendly, high throughput screening for ligands and inhibitors of carbohydrate modifying enzymes

This paper describes the impact of cloud computing and the use of GPUs on the performance of Autodock and Gromacs respectively. Cloud computing was applicable to reducing the ‘‘tail’’ seen in running Autodock on desktop grids and the GPU version of Gromacs showed significant improvement over the CPU version. A large (200,000 compounds) library of small molecules, seven sialic acid analogues of the putative substrate and 8000 sugar molecules were converted into pdbqt format and used to interrogate the Trichomonas vaginalis neuraminidase using Autodock Vina. Good binding energy was noted for some of the small molecules (~-9 kcal/mol), but the sugars bound with affinity of less than -7.6 kcal/mol. The screening of the sugar library resulted in a ‘‘top hit’’ with a-2,3-sialyllacto-N-fucopentaose III, a derivative of the sialyl Lewisx structure and a known substrate of the enzyme. Indeed in the top 100 hits 8 were related to this structure. A comparison of Autodock Vina and Autodock 4.2 was made for the high affinity small molecules and in some cases the results were superimposable whereas in others, the match was less good. The validation of this work will require extensive ‘‘wet lab’’ work to determine the utility of the workflow in the prediction of potential enzyme inhibitors.

“I’m Not Waving, I’m Drowning”: An Autoethnographical Exploration of Biographical Disruption and Reconstruction During Recovery From Prescribed Benzodiazepine Use

Benzodiazepines are group of drugs used mainly as sedatives, hypnotics, muscle relaxants, and anti-epileptics. Tapering off benzodiazepines is, for some users, a painful, traumatic, and protracted process. In this article, I use an autoethnographic approach, adopting the metaphor of water, to examine heuristically my experience of iatrogenic illness and recovery. I draw on personal journals and blog entries and former users’ narratives to consider the particular form of biographical disruption associated with benzodiazepines and the processes involved in identity reconstruction. I emphasize the role of the online community in providing benzodiazepine users such as myself with a co-cultural community through which to share a voice and make sense of our experiences. I explain how the success stories of former users provided me with the hope that I, the “medical victim,” could become the “victor” and in the process construct a new life and fresh identity.
