Testo completo

Abstract (sommario):

Cladophorus Guérin-Méneville, 1830 are endemic Papuan net-winged beetles which take part in highly diverse Müllerian mimicry rings. Available specimens were sequenced for cox1–tRNA-Leu–cox2 mitochondrial DNA fragment and the species delimitations were based on the genetic distance, phylogenetic analysis, and morphology. Three earlier described species were identified in the recently collected material and further 10 species are described: C. pallescens sp. nov., C. bicolor sp. nov., C. craterensis sp. nov., C. motykai sp. nov., C. mindikensis sp. nov., C. kailakiensis sp. nov., C. manokwarensis sp. nov., C. haiaensis sp. nov., C. humeralis sp. nov., and C. boceki sp. nov. DNA-based identifications provided some ambiguous results and closely related species could not be robustly delimited using solely molecular data. Additionally, the species limits were based on clearly defined morphological characters and the morphological differentiation was found unlinked from the genetic divergence. Colour patterns cannot be used for identification because all species available in more specimens were polymorphic and followed various local co-mimics. The Papuan fauna of Cladophorus is very diverse and the closely related species regularly occur in limited regions. Differentiation within restricted ranges is therefore considered as the main speciation mode.

Abstract (sommario):

The genus Microcerotermes Silvestri is revised in an area covering New Guinea, the Bismarck Islands and the Solomon Islands. The presence and status of M. biroi (Desneux), M. papuanus Holmgren and M. repugnans Hill are confirmed. Microcerotermes brevior (Desneux), formerly treated as a subspecies or a synonym of M. biroi, is raised to specific rank. Microcerotermes piliceps Snyder, formerly considered a junior synonym of M. biroi, is recognised as valid; M. umbritarsus Hill and M. froggatti Hill are transferred from the synonymy of M. biroi to that of M. piliceps. The Australian species, M. taylori Hill, is reported from southern New Guinea. Four new species: M. luluai, sp. nov., M. cupreiceps, sp. nov.,M. bouilloni, sp. nov. and M. flyensis, sp. nov. are described. For each of the ten species recorded from our study area, all castes are described or redescribed, diagnostic characters are outlined, and a distribution map is given. Comparisons are also made with related species from adjacent regions. An identification key, based on the soldier and worker castes, is provided. We hypothesise that the New Guinean Microcerotermes fauna is of mixed Australian/southeast Asian origin.

Abstract (sommario):

Three species of Pleuranthodium were encountered and collected during a survey of gingers at Mount Wilhelm, Chimbu Province, Papua New Guinea. Based on new material, the only previously known Pleuranthodium from this area, P. piundaundense, is described in more detail highlighting new diagnostic characters and its known distribution range is expanded based on identification of older specimens at Edinburgh from two other provinces. Two species so far only known from Mount Wilhelm could not be identified after studying all protologues, types and material from several herbaria. These are here described as new species, P. corniculatum and P. sagittatum. A key with both floral and vegetative characters is provided to all three species. Pleuranthodium corniculatum is distinct in having apical appendages on the calyx, and P. sagittatum has a wrinkled calyx. All species are described and illustrated, and conservation assessments are made.

Abstract (sommario):

Les cycles de transmission des maladies zoonotiques et les facteurs qui les influencent sont difficiles à déterminer, particulièrement lorsqu’ils sont dus à des agents pathogènes généralistes dépendant de plusieurs espèces hôtes et vectrices pour être transmis. De plus, perturbations anthropiques et changements climatiques exercent de fortes pressions sur les systèmes hôtes-pathogène-vecteurs pouvant modifier les cycles de transmission. Une approche globale à différentes échelles spatiales est alors nécessaire pour caractériser et quantifier l’importance relative de ses facteurs. Cette approche a été utilisée pour étudier l’écologie du cycle de transmission de la leishmaniose cutanée (LC) en Guyane, une maladie vectorielle sylvatique avec de multiples hôtes et vecteurs. Ce cycle, soumis à des pressions anthropiques grandissantes, a vu sa dynamique se modifier, ce qui a entrainé une augmentation du risque de transmission aux populations humaines. Dans cette thèse, nous avons étudié l’influence des facteurs environnementaux, climatiques et anthropiques, à l’échelle globale du biome amazonien et régionale de la Guyane sur la distribution des cas humains de LC, en utilisant des modèles de niches écologiques. Puis, grâce à l’utilisation du séquençage à haut débit et d’outils probabilistes, nous avons observé la réponse des communautés de vecteurs à une échelle régionale dans des sites forestiers soumis à différents degrés de perturbation. Enfin, nous avons contribué à l’amélioration de la gamme d’outils disponibles pour l’identification des phlébotomes en utilisant le MALDI-TOF MS. Cette thèse a permis d’améliorer les connaissances générales du cycle de la LC en Guyane
For many zoonotic diseases, transmission cycles remain difficult to determine, especially when they are due to generalist pathogens that can rely on several host and vector species to be transmitted. In addition, anthropogenic disturbances and climate change have strong impacts on ecosystems and can alter pathogen transmission cycles. Characterization and quantification of the relative importance of factors influencing host-pathogen-vector systems is then central for a global approach aiming to understand pathogen dynamics at different spatial scales. This approach has been used to study the ecology of the transmission cycle of cutaneous leishmaniasis (CL) in French Guiana. This vector-born disease, mainly sylvatic and including multiple hosts and vectors, is influenced by strong anthropic pressures that modified the dynamics of the cycle and led to an increase in the risk of transmission to human populations. In this work, we first explored the influence of environmental, climatic and anthropic factors on the distribution of human cases of CL at the global scale of the Amazonian biome and at the regional scale of French Guiana, using ecological niche modelling, allowing building risk maps. Then we observed the responses of communities of sandflies and known vectors at the regional scale in forest sites facing different disturbance levels. This work was made possible using a metabarcoding approach with high throughput sequencing. Last, we contributed to the improvement of the range of tools available for the identification of sandflies using the MALDI-TOF MS. This thesis contributed to the improvement of the general knowledge of the CL cycle in French Guiana

Abstract (sommario):

AbstractGerman citizens usually leave their home country voluntarily and face fewer barriers, e.g. in terms of freedom of travel or labour market integration. However, when arriving in their host country, they are confronted with the need to adapt to life in a new society. Analysing data from the German Emigration and Remigration Panel Study, we found that half of the emigrants developed a sense of belonging to their new host society. Moreover, we set out to examine this development of host country attachment. Guided by findings from acculturation and expatriate attachment research, we identified factors potentially contributing to host country attachment and tested these in a series of regression models. Permanence of the intended stay is the strongest predictor, and social integration also plays an important role. Host country language competence is also important for the identification processes. Regarding cultural distance, our findings suggest an inverted U-shaped relationship with certain cultural novelty facilitating the development of host country belonging. Moreover, the data point to a complex relationship between cultural characteristics of the target country and factors related to an emotional settlement.

Abstract (sommario):

AbstractBuilding on a recent study (Shepherd et al. in Strategic Management Journal 38:626–644, 2017), this chapter highlights the importance of noticingopportunities as an initial step toward new venture creation. Unsurprisingly, there has been considerable interest in the processes of allocating attention to notice potential opportunities arising from changes in the external environment. We know a great deal about the role of top-down (i.e., based on knowledge and experience) processes of allocating attention to the environment in forming opportunity beliefs worthy of entrepreneurial action. However, in this chapter, we illustrate how bottom-up processes, whereby environmental changes capture entrepreneurs’ attention, shape opportunity identification. Building on the notion of guided attention, we detail an attention model of forming opportunity beliefs for entrepreneurial action that includes both top-down and bottom-up processes for allocating attention. This chapter explains how entrepreneurs can allocate their transient attention to identify potential opportunities from environmental changes. This chapter also describes how allocating sustained entrepreneurial attention influences belief formation about radicaland incremental opportunities requiring entrepreneurial action.

Abstract (sommario):

This work fills a gap that has existed up to now, proposing a series of specific indicators that serve as a manual of good digital marketing practices for the promotion of tourism destinations. According to the proposed model, the variables to take into account are those related to web metrics, SEO positioning, and social networks. Likewise, the indicators and metrics proposed in the tourism destination Malaga (Spain) are applied. In this way, the model can serve as a guide for the managing institutions of tourism destinations that wish to measure the results of their efforts. This analysis facilitates the identification of the strengths of the strategy followed, as well as those that need to be improved. It can also be used to verify the positioning of tourism destinations with respect to their competitors.

Abstract (sommario):

The core dimensions that define what is meant when a person is said to have an ‘intellectual disability’ include evidence of intellectual and functional impairments and disabilities. They will have been first apparent in early childhood, with a significant delay in reaching key developmental milestones. This umbrella term, the definition of which has been refined over time, refers to a highly heterogenous population, given the multiple possible causes of intellectual disability, differences in severity, and the presence of other impairments and disabilities. Core dimensions of alternate definitions emphasize the role of education, life experience, and opportunities in optimizing the acquisition of skills and the identification and subsequent removal of barriers impeding development and full participation. Developmental, biomedical, and functional models inform our understanding of, and interventions for, the high prevalence rates of mental ill health and of challenging behaviours in this population. These different explanatory models guide the assessment and subsequent diagnostic formulation and interventions described in this chapter.

Abstract (sommario):

Research on child and adolescent MDD and bipolar disorder needs to proceed on many fronts to maximize the diagnosis, treatment, and prevention of these disorders. Identification of risk factors – psychological, sociological, familial, and biological – to include studies of biomarkers, genetics and epigenetics, and brain imagining are needed to inform the development of new treatments and prevention programs. Studies are needed in both MDD and bipolar disorder regarding the identification of predictors of clinical outcome and selection of psychosocial and/or pharmacological treatment(s) that are personalized for an individual patient. Maintenance studies are needed to guide optimal treatment duration. Studies focusing on the treatment and prevention of suicide are needed in both MDD and bipolar disorder. More prevention programs are needed in MDD with a focus on a full range of risk factors and the active ingredients and predictors of change that will ultimately guide a specific prevention program for a given patient. Prevention programs in bipolar disorder await further research advances in the identification of risk factors and in the characterization of early signs and symptoms to target those individuals who are at risk for the development of bipolar disorder in youth.

Abstract (sommario):

<p>The variety of transparency, lightness, and shape of cable-supported bridges is being actively utilized in the design of pedestrian bridges. Moreover, the pedestrian bridge, which is demanded to play a key role as a harmonious structure with surrounding landscape, is being reborn as a landmark sculpture. Considering that understanding design trends is very important step to establish design guide lines for future design, existing cable-supported pedestrian bridges developed until recently have been investigated considering structural material, structural system, and architectural styles. The visual inspiration of the pedestrian bridge is felt in the sense of the structure and the structural form is determined to satisfy the geometric design requirements while considering the efficiency and stability of the cable structure. Therefore, it is needed to identify the main variables affecting the cable-support structures and understand the true beauty of bridges by comparing and analyzing various bridge cases based on major variables. This paper will focus mainly on the following issues:</p><p>(1) the classification of types of cable-supported pedestrian bridges; (2) the identification of the important factors affecting structural forms and (3) an integrated framework for future pedestrian bridges considering form, function, and behavior. Note that the relationship between structural form and visual form is explained using graphical approach. It is expected that this study will help to explore future pedestrian bridges considering bridge aesthetics.</p>

Abstract (sommario):

The piezoelectric impedance/admittance-based damage detection has been recognized to be sensitive to small-sized damage due to its high frequency measurement capability. Recently, a new class of admittance-based damage detection schemes has been proposed, in which the piezoelectric transducer is integrated with a tunable inductive circuitry. The present research focuses on exploiting the tunable nature of the piezoelectric admittance sensor for the effective identification of damage. In particular, we incorporate the Bayesian inference network into the damage detection process which can intelligently guide the accurate identification of damage location and severity by taking full advantage of the baseline model and measurement as well as the online measurement. As the tunable sensor can provide greatly enriched measurement information, the Bayesian inference can adequately utilize such information and furthermore directly and continuously update the structural model until the model prediction matches with the measurement results. This new approach takes into account the model uncertainty, measurement error, and incompleteness of measurements. Extensive numerical analyses and experimental studies are carried out on a panel structure for methodology demonstration and validation.

Abstract (sommario):

As road safety issues become increasingly complex and involve various stakeholders, designing of safety actions as on-board vehicle safety systems or public policy measures needs knowledge that describes the performance level to fulfil the objectives. Performance is assessed by evaluating designed actions as regards their functional specifications. By its ability to create new knowledge, evaluation is also used to improve existing actions or to specify road safety strategies. However, given the complexity of the evaluation activity and its context, experts consider that the existing knowledge is insufficient. One considers that this situation reflects the lack of a theoretical framework. In particular, there is no way to identify emerging assessment issues due to the insertion of new safety systems and the emergence of new users’ behaviours. In this paper, we introduce a framework that describes the design of the evaluation methods in the field of road safety. It is used as a guide to build new evaluation models for specific stakeholders and viewpoints. This framework is based on the identification of the objectives to be achieved and the use of the evaluators’ expertise.

Abstract (sommario):

RGB-infrared (IR) person re-identification is a challenging task due to the large modality gap between RGB and IR images. Many existing methods bridge the modality gap by style conversion, requiring high-similarity images exchanged by complex CNN structures, like GAN. In this paper, we propose a highly compact modality-aware style adaptation (MSA) framework, which aims to explore more potential relations between RGB and IR modalities by introducing new related modalities. Therefore, the attention is shifted from bridging to filling the modality gap with no requirement on high-quality generated images. To this end, we firstly propose a concise feature-free image generation structure to adapt the original modalities to two new styles that are compatible with both inputs by patch-based pixel redistribution. Secondly, we devise two image style quantification metrics to discriminate styles in image space using luminance and contrast. Thirdly, we design two image-level losses based on the quantified results to guide the style adaptation during an end-to-end four-modality collaborative learning process. Experimental results on two datasets SYSU-MM01 and RegDB show that MSA achieves significant improvements with little extra computation cost and outperforms the state-of-the-art methods.

Abstract (sommario):

Rapid progress in molecular biology, much sparked by the human Genome Project, is opening a new era in medicine and biology. The development of in-vivo micro-imaging technology for small animals (mice and rats) has generated unprecedented opportunities for studying the structural and physiologic properties exhibited by different genes in a cost-effective and low-risk means. This knowledge, in turn, will help guide the study in human genetic system. Micro-computed tomograph (microCT) with resolution on the scale of micrometer is a new technique for obtaining the 3D images of the internal structure of small objects [1,2]. Its biological and medical applications include noninvasively screening animals for genetic mutations and identification as well as monitoring of structural and physiology properties that are linked with specific genes. This paper reports on our preliminary investigation on two aspects of this new imaging technique: (1) an initial experience of instrumentation capability and limitation, and (2) the contrast enhancement strategy necessary for organ-specific anatomic and physiologic studies.

Abstract (sommario):

Parallel programs are imperative for improving performance and problem solving, having an increasing demand on implementing efficient parallel programming techniques. This entails new challenges on software testing to ensure their quality and reliability. Structural testing is a technique that allows the identification of concurrency defects by analyzing the internal structure of the program. However, the non-determinism of concurrent programs has implications in the testing activity, requiring the use of structured methods to reveal defects. Testing criteria support the selection of test cases in a systematic form by statically analysing elements of concurrent programs. We found that there are currently gaps in the definition of testing criteria contemplating scenarios with elements that are dynamically evaluated, such as the execution of communication primitives inside loops. The objective of this project is to define structural testing criteria to guide the selection of test cases, improving the reliability of concurrent programs by revealing non-determinism related errors present in repetition structures. We developed a Concurrent Defects Taxonomy, identifying and classifying concurrency types of defects found in related literature. The analysis of such defects, paths inside loops, number of loop iterations, and nested loops allow us to model the proposed structural testing criteria. We define new sets and associations related to communication and synchronization flows for message-passing programs, establishing a model for testing criteria. We implemented the proposed test model in ValiMPI, a testing tool prototype, considering the new concepts defined in our test model, generating required elements and evaluating coverage after constructing loop paths. For the application evaluation of criteria we perform an empirical study with statistical validation, indicating the results for cost, effectiveness and strength. Our experimental evaluation demonstrated that the proposed testing criteria generates required elements that support the identification of concurrency defects occurring in different loop iterations, when having communicational events with non-deterministic behavior.

Abstract (sommario):

After over five decades of efforts, computers have recently begun to plan chemical syntheses of complex targets at a level comparable to human experts. With this milestone achieved, it is now time to ponder not only how the machines will accelerate and multiplex synthetic design, but also how they will guide the discovery of new targets having desired properties.

Abstract (sommario):

Highly imperiled Oregon white oak ecosystems are a regional conservation priority of numerous organizations, including Oregon Metro, a regional government serving over one million people in the Portland area. Previously dominant systems in the Pacific Northwest, upland prairie and oak woodlands are now experiencing significant threat, with only 2% remaining in the Willamette Valley in small fragments (Hulse et al. 2002). These fragments are of high conservation value because of the rich biodiversity they support, including rare and endemic species, such as Delphinium leucophaeum (Oregon Department of Agriculture, 2020). Since 2010, Metro scientists and volunteers have collected phenology data on approximately 140 species of forbs and graminoids in regional oak prairie and woodlands. Phenology is the study of life-stage events in plants and animals, such as budbreak and senescence in flowering plants, and widely acknowledged as a sensitive indicator of environmental change (Parmesan 2007). Indeed, shifts in plant phenology have been observed over the last few decades as a result of climate change (Parmesan 2006). In oak systems, these changes have profound implications for plant community composition and diversity, as well as trophic interactions and general ecosystem function (Willis 2008). While the original intent of Metro’s phenology data-collection was to track long-term phenology trends, limitations in data collection methods have made such analysis difficult. Rather, these data are currently used to inform seasonal management decisions on Metro properties, such as when to collect seed for propagation and when to spray herbicide to control invasive species. Metro is now interested in fine-tuning their data-collection methods to better capture long-term phenology trends to guide future conservation strategies. Addressing the regional and global conservation issues of our time will require unprecedented collaboration. Phenology data collected on Metro properties is not only an important asset for Metro’s conservation plan, but holds potential to support broader research on a larger scale. As a leader in urban conservation, Metro is poised to make a meaningful scientific contribution by sharing phenology data with regional and national organizations. Data-sharing will benefit the common goal of conservation and create avenues for collaboration with other scientists and conservation practitioners (Rosemartin 2013). In order to support Metro’s ongoing conservation efforts in Oregon white oak systems, I have implemented a three-part master’s project. Part one of the project examines Metro’s previously collected phenology data, providing descriptive statistics and assessing the strengths and weaknesses of the methods by which the data were collected. Part two makes recommendations for improving future phenology data-collection methods, and includes recommendations for datasharing with regional and national organizations. Part three is a collection of scientific vouchers documenting key plant species in varying phases of phenology for Metro’s teaching herbarium. The purpose of these vouchers is to provide a visual tool for Metro staff and volunteers who rely on plant identification to carry out aspects of their job in plant conservation. Each component of this project addresses specific aspects of Metro’s conservation program, from day-to-day management concerns to long-term scientific inquiry.
