Cross-cultural adaptation of the Safety Attitudes Questionnaire - Short Form 2006 for Brazil

The objective of this study was to perform a cross-cultural adaptation of the Safety Attitudes Questionnaire - Short Form 2006 for Brazil. The instrument was applied in six hospitals in three regions of Brazil. Content, face, and construct validity was performed. Analysis of the instrument's reliability was performed by verifying the items' internal consistency through Cronbach's alpha. The sample was composed of 1301 professionals working in clinical and surgical wards of six hospitals. Confirmatory analysis showed that the model including 41 items was satisfactory. The Portuguese version presented an alpha of 0.89. The item-total correlations among the domains were moderate to strong, except for the domain Stress Recognition. We concluded that the instrument's version adapted to Portuguese and applied in our sample is valid and reliable.

Hand in hand: public endorsement of climate change mitigation and adaptation

This research investigated how an individual’s endorsements of mitigation and adaptation relate to each other, and how well each of these can be accounted for by relevant social psychological factors. Based on survey data from two European convenience samples (N = 616 / 309) we found that public endorsements of mitigation and adaptation are strongly associated: Someone who is willing to reduce greenhouse gas emissions (mitigation) is also willing to prepare for climate change impacts (adaptation). Moreover, people endorsed the two response strategies for similar reasons: People who believe that climate change is real and dangerous, who have positive attitudes about protecting the environment and the climate, and who perceive climate change as a risk, are willing to respond to climate change. Furthermore, distinguishing between (spatially) proximal and distant risk perceptions suggested that the idea of portraying climate change as a proximal (i.e., local) threat might indeed be effective in promoting personal actions. However, to gain endorsement of broader societal initiatives such as policy support, it seems advisable to turn to the distant risks of climate change. The notion that “localising” climate change might not be the panacea for engaging people in this domain is discussed in regard to previous theory and research.

Climate sensitivity across marine domains of life: limits to evolutionary adaptation shape species interactions, supplementary material

Organisms in all domains, Archaea, Bacteria, and Eukarya will respond to climate change with differential vulnerabilities resulting in shifts in species distribution, coexistence, and interactions. The identification of unifying principles of organism functioning across all domains would facilitate a cause and effect understanding of such changes and their implications for ecosystem shifts. For example, the functional specialization of all organisms in limited temperature ranges leads us to ask for unifying functional reasons. Organisms also specialize in either anoxic or various oxygen ranges, with animals and plants depending on high oxygen levels. Here, we identify thermal ranges, heat limits of growth, and critically low (hypoxic) oxygen concentrations as proxies of tolerance in a meta-analysis of data available for marine organisms, with special reference to domain-specific limits. For an explanation of the patterns and differences observed, we define and quantify a proxy for organismic complexity across species from all domains. Rising complexity causes heat (and hypoxia) tolerances to decrease from Archaea to Bacteria to uni- and then multicellular Eukarya. Within and across domains, taxon-specific tolerance limits likely reflect ultimate evolutionary limits of its species to acclimatization and adaptation. We hypothesize that rising taxon-specific complexities in structure and function constrain organisms to narrower environmental ranges. Low complexity as in Archaea and some Bacteria provide life options in extreme environments. In the warmest oceans, temperature maxima reach and will surpass the permanent limits to the existence of multicellular animals, plants and unicellular phytoplankter. Smaller, less complex unicellular Eukarya, Bacteria, and Archaea will thus benefit and predominate even more in a future, warmer, and hypoxic ocean.

A Light-Weight On-Chip Monitoring Network for Dynamic Adaptation and Calibration

Current nanometer technologies suffer within-die parameter uncertainties, varying workload conditions, aging, and temperature effects that cause a serious reduction on yield and performance. In this scenario, monitoring, calibration, and dynamic adaptation become essential, demanding systems with a collection of multi purpose monitors and exposing the need for light-weight monitoring networks. This paper presents a new monitoring network paradigm able to perform an early prioritization of the information. This is achieved by the introduction of a new hierarchy level, the threshing level. Targeting it, we propose a time-domain signaling scheme over a single-wire that minimizes the network switching activity as well as the routing requirements. To validate our approach, we make a thorough analysis of the architectural trade-offs and expose two complete monitoring systems that suppose an area improvement of 40% and a power reduction of three orders of magnitude compared to previous works.

Methodology for developing a Speech into Sign Language Translation System in a New Semantic Domain

This paper proposes a methodology for developing a speech into sign language translation system considering a user-centered strategy. This method-ology consists of four main steps: analysis of technical and user requirements, data collection, technology adaptation to the new domain, and finally, evalua-tion of the system. The two most demanding tasks are the sign generation and the translation rules generation. Many other aspects can be updated automatical-ly from a parallel corpus that includes sentences (in Spanish and LSE: Lengua de Signos Española) related to the application domain. In this paper, we explain how to apply this methodology in order to develop two translation systems in two specific domains: bus transport information and hotel reception.

Adapting a speech into sign language translation system to a new domain

This paper presents a methodology for adapting an advanced communication system for deaf people in a new domain. This methodology is a user-centered design approach consisting of four main steps: requirement analysis, parallel corpus generation, technology adaptation to the new domain, and finally, system evaluation. In this paper, the new considered domain has been the dialogues in a hotel reception. With this methodology, it was possible to develop the system in a few months, obtaining very good performance: good speech recognition and translation rates (around 90%) with small processing times.

A sharing-based approach to supporting adaptation in service compositions

Data-related properties of the activities involved in a service composition can be used to facilitate several design-time and run-time adaptation tasks, such as service evolution, distributed enactment, and instance-level adaptation. A number of these properties can be expressed using a notion of sharing. We present an approach for automated inference of data properties based on sharing analysis, which is able to handle service compositions with complex control structures, involving loops and sub-workflows. The properties inferred can include data dependencies, information content, domain-defined attributes, privacy or confidentiality levels, among others. The analysis produces characterizations of the data and the activities in the composition in terms of minimal and maximal sharing, which can then be used to verify compliance of potential adaptation actions, or as supporting information in their generation. This sharing analysis approach can be used both at design time and at run time. In the latter case, the results of analysis can be refined using the composition traces (execution logs) at the point of execution, in order to support run-time adaptation.

Generating Linked-Data based Domain-Specific Sentiment Lexicons from Legacy Language and Semantic Resources

We present a methodology for legacy language resource adaptation that generates domain-specific sentiment lexicons organized around domain entities described with lexical information and sentiment words described in the context of these entities. We explain the steps of the methodology and we give a working example of our initial results. The resulting lexicons are modelled as Linked Data resources by use of established formats for Linguistic Linked Data (lemon, NIF) and for linked sentiment expressions (Marl), thereby contributing and linking to existing Language Resources in the Linguistic Linked Open Data cloud.

Methodology for developing an advanced communications system for the Deaf in a new domain

A methodology for developing an advanced communications system for the Deaf in a new domain is presented in this paper. This methodology is a user-centred design approach consisting of four main steps: requirement analysis, parallel corpus generation, technology adaptation to the new domain, and finally, system evaluation. During the requirement analysis, both the user and technical requirements are evaluated and defined. For generating the parallel corpus, it is necessary to collect Spanish sentences in the new domain and translate them into LSE (Lengua de Signos Española: Spanish Sign Language). LSE is represented by glosses and using video recordings. This corpus is used for training the two main modules of the advanced communications system to the new domain: the spoken Spanish into the LSE translation module and the Spanish generation from the LSE module. The main aspects to be generated are the vocabularies for both languages (Spanish words and signs), and the knowledge for translating in both directions. Finally, the field evaluation is carried out with deaf people using the advanced communications system to interact with hearing people in several scenarios. In this evaluation, the paper proposes several objective and subjective measurements for evaluating the performance. In this paper, the new considered domain is about dialogues in a hotel reception. Using this methodology, the system was developed in several months, obtaining very good performance: good translation rates (10% Sign Error Rate) with small processing times, allowing face-to-face dialogues.

Two-domain reconstitution of a functional protein histidine kinase

In prokaryotes, in the absence of protein serine/threonine/tyrosine kinases, protein histidine kinases play a major role in signal transduction involved in cellular adaptation to various environmental changes and stresses. Histidine kinases phosphorylate their cognate response regulators at a specific aspartic acid residue with ATP in response to particular environmental signals. In this His-Asp phosphorelay signal transduction system, it is still unknown how the histidine kinase exerts its enzymatic function. Here we demonstrate that the cytoplasmic kinase domain of EnvZ, a transmembrane osmosensor of Escherichia coli can be further divided into two distinct functional subdomains: subdomain A [EnvZ(C)⋅(223–289); 67 residues] and subdomain B [EnvZ(C)⋅(290–450); 161 residues]. Subdomain A, with a high helical content, contains the autophosphorylation site, H–243, and forms a stable dimer having the recognition site for OmpR, the cognate response regulator of EnvZ. Subdomain B, an α/β-protein, exists as a monomer. When mixed, the two subdomains reconstitute the kinase function to phosphorylate subdomain A at His-243 in the presence of ATP. Subsequently, the phosphorylated subdomain A is able to transfer its phosphate group to OmpR. The two-domain structure of this histidine kinase provides an insight into the structural arrangement of the enzyme and its transphosphorylation mechanism.

Identification and characterization of periplasmic proteins implicated in the adaptation of Helicobacter pylori to the human gastric niche

Helicobacter pylori è un batterio Gram-negativo in grado di colonizzare la mucosa gastrica umana e persistere per l'intero arco della vita dell'ospite. E' associato a patologie gastrointestinali, quali gastrite cronica, ulcere gastriche e duodenali, adenocarcinomi e linfomi gastrici. Si tratta di uno dei patogeni più diffusi, presente in circa metà della popolazione mondiale, e il solo che si è adattato a vivere nell'ambiente ostile dello stomaco umano. Molteplici sono i fattori di virulenza che permettono al batterio la colonizzazione della nicchia gastrica e contribuiscono, anche attraverso l' induzione di una risposta infiammatoria, a profonde modificazioni dell' omeostasi gastrica. Queste ultime si associano, ad esempio, all'iperproduzione di fattori proinfiammatori, ad alterazioni sia della regolazione della secrezione acida gastrica sia del ciclo cellulare e della morte cellulare programmata (apoptosi) delle cellule epiteliali gastriche, a disordini nel metabolismo del ferro e a carenze di elementi essenziali. Studi sulla diversità genetica di H. pylori osservata in ceppi isolati da varie regioni del mondo, dimostrano che tale batterio ha avuto una coevoluzione col genere umano attraverso la storia, ed è verosimile che H. pylori sia stato un costituente del microbiota gastrico per almeno 50.000 anni. Scopo della tesi è stato quello di identificare e caratterizzare proteine importanti per la colonizzazione e l'adattamento di H. pylori alla nicchia gastrica. In particolare gli sforzi si sono concentrati su due proteine periplasmatiche, la prima coinvolta nella difesa antiossidante (l'enzima catalasi-like, HP0485), e la seconda nel trasporto di nutrienti presenti nell'ambiente dello stomaco all'interno della cellula (la componente solubile di un ABC transporter, HP0298). La strategia utilizzata prevede un'analisi bioinformatica preliminare, l'ottenimento del gene per amplificazione, mediante PCR, dal genoma dell'organismo, la costruzione di un vettore per il clonaggio, l'espressione eterologa in E. coli e la successiva purificazione. La proteina così ottenuta viene caratterizzata mediante diverse tecniche, quali spettroscopia UV, dicroismo circolare, gel filtrazione analitica, spettrometria di massa. Il capitolo 1 contiene un'introduzione generale sul batterio, il capitolo 2 e il capitolo 3 descrivono gli studi relativi alle due proteine e sono entrambi suddivisi in un abstract iniziale, un'introduzione, la presentazione dei risultati, la discussione di questi ultimi, i materiali e i metodi utilizzati. La catalasi-like (HP0485) è una proteina periplasmatica con struttura monomerica, appartenente ad una famiglia di enzimi a funzione per la maggior parte sconosciuta, ma evolutivamente correlati alla ben nota catalasi, attore fondamentale nella difesa di H. pylori, grazie alla sua azione specifica di rimozione dell'acqua ossigenata. HP0485, pur conservando il fold catalasico e il legame al cofattore eme, non può compiere la reazione di dismutazione dell'acqua ossigenata; possiede invece un'attività perossidasica ad ampio spettro, essendo in grado di accoppiare la riduzione del perossido di idrogeno all'ossidazione di diversi substrati. Come la catalasi, lavora ad alte concentrazioni di aqua ossigenata e non arriva a saturazione a concentrazioni molto elevate di questo substrato (200 mM); la velocità di reazione catalizzata rimane lineare anche a questi valori, aspetto che la differenzia dalle perossidasi che vengono in genere inattivate da concentrazioni di perossido di idrogeno superiori a 10-50 mM. Queste caratteristiche di versatilità e robustezza suggeriscono che la catalasi-like abbia un ruolo di scavenger dell'acqua ossigenata e probabilmente anche un'altra funzione connessa al suo secondo substrato, ossia l'ossidazione di composti nello spazio periplasmatico cellulare. Oltre alla caratterizzazione dell'attività è descritta anche la presenza di un ponte disolfuro, conservato nelle catalasi-like periplasmatiche, con un ruolo nell'assemblaggio dell'eme per ottenere un enzima attivo e funzionale. La proteina periplasmatica HP0298, componente di un sistema di trasporto ABC, è classificata come trasportatore di dipeptidi e appartiene a una famiglia di proteine in grado di legare diversi substrati, tra cui di- e oligopeptidi, nichel, eme, glutatione. Benchè tutte associate a trasportatori di membrana batterici, queste proteine presentano un dominio di legame al substrato che risulta essere conservato nei domini extracellulari di recettori specifici di mammifero e uomo. Un esempio sono i recettori ionotropici e metabotropici del sistema nervoso. Per caratterizzare questa proteina è stato messo a punto un protocollo di ligand-fishing accoppiato alla spettrometria di massa. La proteina purificata, avente un tag di istidine, è stata incubata con un estratto cellulare di H. pylori per poter interagire con il suo substrato specifico all'interno dell'ambiente naturale in cui avviene il legame. Il complesso proteina-ligando è stato poi purificato per cromatografia di affinità e analizzato mediante HPLC-MS. L'identificazione dei picchi differenziali tra campioni con la proteina e 5 campioni di controllo ha portato alla caratterizzazione di pentapeptidi particolarmente ricchi in aminoacidi idrofobici e con almeno un residuo carico negativamente. Considerando che H. pylori necessita di alcuni aminoacidi essenziali, per la maggior parte idrofobici, e che lo stomaco umano è particolarmente ricco di peptidi prodotti dalla digestione delle proteine introdotte con il cibo, il ruolo fisiologico di HP0298 potrebbe essere l'internalizzazione di peptidi, con caratteristiche specifiche di lunghezza e composizione, che sono naturalmente presenti nella nicchia gastrica.

Innovation and Development in the Age of Climate Change Adaptation: Open or Closed?

Change Adaptation: Open or Closed? Paper read at the Second African International Economic Law Network Conference, 7-8 March 2013, Wits School of Law, Johannesburg, South Africa. In a time of rapid convergence of technologies, goods, services, hardware, software, the traditional classifications that informed past treaties fail to remove legal uncertainty, or advance welfare and innovation. As a result, we turn our attention to the role and needs of the public domain at the interface of existing intellectual property rights and new modes of creation, production and distribution of goods and services. The concept of open culture would have it that knowledge should be spread freely and its growth should come from further developing existing works on the basis of sharing and collaboration without the shackles of intellectual property. Intellectual property clauses find their way into regional, multilateral, bilateral and free trade agreements more often than not, and can cause public discontent and incite unrest. Many of these intellectual property clauses raise the bar on protection beyond the clauses found in the WTO Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS). In this paper we address the question of the protection and development of the public domain in service of open innovation in accord with Article 15 of the International Covenant on Economic, Social and Cultural Rights (ICESCR) in light of the Objectives (Article 7) and Principles (Article 8) set forth in TRIPS. Once areas of divergence and reinforcement between the intellectual property regime and human rights have been discussed, we will enter into options that allow for innovation and prosperity in the global south. We then conclude by discussing possible policy developments.
