    UPCEO, connecting statistics and people using R

    A methodology and a tool that implements this methodology are developed using R to construct a web site that allows a lay user to consult statistical information owned by an institution and stored in a cloud database. This methodology was developed followin g the open - data philosophy and was implemented with open -source software using R as a key element. The proposed methodology was applied successfully to develop a tool to manage the data of the Centre d’Estudis d’Opinió, but it can be applied to another sta tistical center to enable open access to its data. The system is deployed on a cloud infrastructure that scales according to demand, implementing a 24/7 solution. A user (or a computer program) can access the information on the website using the R language as a communication channel or using a programming application interface. Additionally, in the R language, a common framework can be defined to structure the various processes involved in any statistical operation.Peer ReviewedPostprint (published version

    In-person school reopening and the spread of SARS-CoV-2 during the second wave in Spain

    Get PDF
    We investigate the effects of school reopening on the evolution of COVID-19 infections during the second wave in Spain studying both regional and age-group variation within an interrupted time-series design. Spain's 17 Autonomous Communities reopened schools at different moments in time during September 2020. We find that in-person school reopening correlates with a burst in infections in almost all those regions. Data from Spanish regions gives a further leverage: in some cases, pre-secondary and secondary education started at different dates. The analysis of those cases does not allow to conclude whether reopening one educational stage had an overall stronger impact than the other. To provide a plausible mechanism connecting school reopening with the burst in contagion, we study the Catalan case in more detail, scrutinizing the interrupted time-series patterns of infections among age-groups and the possible connections between them. The stark and sudden increase in contagion among older children (10–19) just after in-person school reopening appears to drag the evolution of other age-groups according to Granger causality. This might be taken as an indirect indication of household transmission from offspring to parents with important societal implications for the aggregate dynamics of infections.Peer ReviewedPostprint (published version

    A note on facultative kleptoparasitism in Prionyx kirbii (Hymenoptera: Sphecidae) as a consequence of multi-specific shared nesting site, with description of its prepupa

    Get PDF
    Observations of a female of Prionyx kirbii at an aggregation of Stizus continuus revealed an alternative nesting behaviour of the first wasp due to the presence of the second one. The overlap of some resources (prey, kind of soil) allowed P. kirbii to act as a kleptoparasite of S. continuus. The observed female often re-used as nests pre-existing S. continuus emergence holes, but no S. continuus nests. The prey were obtained sometimes by stealing the grasshoppers from S. continuus nests and/or by attacking the females while carrying the prey. From a review of interspecific kleptoparasitism among sphecoid wasps it appears that family Sphecidae includes the highest number of facultative parasitism cases and this finding is discussed. In addition, the description of the prepupa of P. kirbii is given and is shown to be in agreement with the description of the mature larvae of the other species of the genus

    Complex-to-predict generational shift between nested and clustered organization of individual prey networks in digger wasps

    Although diet has traditionally been considered to be a property of the species or populations as a whole, there is nowadays extensive knowledge that individual specialization is widespread among animal populations. Nevertheless, the factors determining the shape of interactions within food webs remain largely undiscovered, especially in predatory insects. We used an aggregation of the digger wasp Bembix merceti to 1) analyse patterns of individual prey use across three flying seasons in a network-based context; and 2) test the effect of four potential factors that might explain network topologies (wasp mass, nest spatial distribution, simultaneous nest-provisioning, prey availability). Inter-individual diet variation was found in all three years, under different predator-prey network topologies: Individuals arranged in dietary clusters and displayed a checkerboard pattern in 2009, but showed nestedness in 2008 and 2010. Network topologies were not fully explained by the tested factors. Larger females consumed a higher proportion of the total number of prey species captured by the population as a whole, in such a way that nested patterns may arise from mass-dependent prey spectrum width. Conversely, individuals with similar body mass didn't form clusters. Nested patterns seemed to be associated with a greater availability of the main prey species (a proxy for reduced intra-specific competition). Thus, according with theory, clusters seemed to appear when competition increased. On the other hand, the nests of the individuals belonging to a given cluster were not more closely located, and neither did individuals within a cluster provision their nests simultaneously. Thus, a female-female copying behaviour during foraging was unlikely. In conclusion, wasp populations can maintain a considerable individual variation across years under different food web organizations. The tested factors only partially accounted for the shift in network properties, and new analyses should be carried out to elucidate how diet network topologies arise in wasp populations. © 2014 Ballesteros et al.This work was supported by the Projects SA094A09 and SA010A06 (Junta de Castilla y León) and CGL2010-16730 (MICINN).

    Cognitive prognosis of acquired brain injury patients using machine learning techniques

    The cognitive prognosis of acquired brain injury (ABI) patients is a valuable tool for an improved and personalized treatment. In this paper, we explore the task of automatic cognitive prognosis of ABI patients via machine learning techniques. Based on a set of pre-treatment assessments, distinct classifiers are trained to predict whether the patient will improve in one or any of three cognitive areas: attention, memory, and executive functioning. Results show that variables such as the age at the moment of the injury, the patient's etiology, or the neuropsychological evaluation scores obtained before the treatment are relevant for prognosis and easily yield statistically significant accuracies. Additionally, the prognostic relevance of these and other variables is studied by means of standard feature selection methodologies. The outputs of the present paper add to the discussion on current cognitive rehabilitation practices and push towards the exploitation of existing technologies for improving medical evaluations and treatments.We thank all the patients and staff from Institut Guttmann who cooperated in data collection.

    Depth sensors-based upper limb motion capture system for functional neurorehabilitation

    Get PDF
    Versatile and accurate motion capture systems, with the required properties to be integrated within both clinical and domiciliary environments, would represent a significant advance in following the progress of the patients as well as in allowing the incorporation of new data exploitation and analysis methods to enhance the functional neurorehabilitation therapeutic processes. Besides, these systems would permit the later development of new applications focused on the automatization of the therapeutic tasks in order to increase the therapist/patient ratio, thus decreasing the costs [1]. However, current motion capture systems are not still ready to work within uncontrolled environments
