Analyzing environmental‐trait interactions in ecological communities with fourth‐corner latent variable models
2021
In ecological community studies it is often of interest to study the effect of species related trait variables on abundances or presence-absences. Specifically, the interest may lay in the interactions between environmental and trait variables. An increasingly popular approach for studying such interactions is to use the so-called fourth-corner model, which explicitly posits a regression model where the mean response of each species is a function of interactions between covariate and trait predictors (among other terms). On the other hand, many of the fourth-corner models currently applied in the literature are too simplistic to properly account for variation in environmental and trait resp…
Blind source separation for non-stationary random fields
2022
Regional data analysis is concerned with the analysis and modeling of measurements that are spatially separated by specifically accounting for typical features of such data. Namely, measurements in close proximity tend to be more similar than the ones further separated. This might hold also true for cross-dependencies when multivariate spatial data is considered. Often, scientists are interested in linear transformations of such data which are easy to interpret and might be used as dimension reduction. Recently, for that purpose spatial blind source separation (SBSS) was introduced which assumes that the observed data are formed by a linear mixture of uncorrelated, weakly stationary random …
On the usage of joint diagonalization in multivariate statistics
2022
Scatter matrices generalize the covariance matrix and are useful in many multivariate data analysis methods, including well-known principal component analysis (PCA), which is based on the diagonalization of the covariance matrix. The simultaneous diagonalization of two or more scatter matrices goes beyond PCA and is used more and more often. In this paper, we offer an overview of many methods that are based on a joint diagonalization. These methods range from the unsupervised context with invariant coordinate selection and blind source separation, which includes independent component analysis, to the supervised context with discriminant analysis and sliced inverse regression. They also enco…

Multivariate time series observations are increasingly common in multiple fields of science but the complex dependencies of such data often translate into intractable models with large number of parameters. An alternative is given by first red…
Test of the Latent Dimension of a Spatial Blind Source Separation Model
2024
We assume a spatial blind source separation model in which the observed multivariate spatial data is a linear mixture of latent spatially uncorrelated random fields containing a number of pure white noise components. We propose a test on the number of white noise components and obtain the asymptotic distribution of its statistic for a general domain. We also demonstrate how computations can be facilitated in the case of gridded observation locations. Based on this test, we obtain a consistent estimator of the true dimension. Simulation studies and an environmental application in the Supplemental Material demonstrate that our test is at least comparable to and often outperforms bootstrap-bas…
Forme del fritto: alcune esperienze di consumo
2020
Questo capitolo propone uno studio sul campo di una pratica alimentare che caratterizza la Sicilia e, in particolare, la città di Palermo: lo street food. Lo street food palermitano si caratterizza per essere indissolubilmente legato alla frittura, una modalità di cottura pervasiva tanto nei mercati storici della città, quanto in quei luoghi chiusi che, in forme diverse, tentano di replicarne l'esperienza. Il fritto è, ancor prima che una modalità di cottura dei cibi, un particolare dispositivo ambientale e sensoriale, che pregiudica olfattivamente gli spazi di vendita e consumo e che spinge, alcuni format di distribuzione, a limitarne la pervasività. Vedremo, in questo senso, come la diffe…
Monimuotoisuuden johtamisen ristiriitaisuus : diskurssianalyysi suomalaisista mediateksteistä
2010
The diversity management paradox – A discourse analysis of Finnish media texts The phenomenon called ‘diversity management’ originating in North America has recently emerged in Europe. Although the importance of a diverse workforce has been emphasised in Finland, research on diversity management has been rather limited. In this study, we examine the discursively constructed meanings of diversity and diversity management in Finnish media texts. On the basis of our analysis, we (re)constructed five discourses for understanding diversity and diversity management. Based on our analysis, we suggest that the significance of the diversity discussion in Finland lies primarily in encouraging busines…
Caracterización morfológica y molecular de Paragonimus caliensis Little 1968 y Paragonimus mexicanus Miyazaki & Ishii 1968 (Digenea: Paragonimidae) e…
2018
La paragonimiasis es una enfermedad pulmonar granulomatosa inflamatoria crónica causada por trematodos del género Paragonimus. En América Latina, P. mexicanus Miyazaki & Ishii 1968 es la única especie confirmada que causa infecciones humanas. Paragonimus caliensis Little 1968, es una especie poco común a menudo considerada sinónima junior de P. mexicanus. Recientemente, el estudio molecular y morfológico de dos tipos de metacercarias de Paragonimus en Costa Rica proporcionó la evidencia de que P. caliensis es una especie separada de P. mexicanus. En el presente estudio se utilizaron herramientas moleculares, filogenéticas y morfológicas para caracterizar cuatro poblaciones de Paragonimus en…
Diversity in Teams : Perceptions of Team Learning Behaviour in a Military Staff Exercise
2020
The aim of this study is to analyse diversity in team learning behaviour between and among national respondents’ perceptions during a military staff exercise (CJSE). Edmondson’s team learning behaviour model is used as the theoretical basis of the study. The results showed statistically significant differences both between and among national respondents’ perceptions. The research results indicate that team leader coaching, team psychological safety, the importance of obtaining expert knowledge as well as pre-exercise training are perceived to be crucial for team learning behaviour. The study has theoretical and practical implications for a more nuanced understanding of the diversity of team…
