Sensitivity Analysis in Nonrandomized Longitudinal Mediation Analysis
2021
Mediation analysis relies on an untestable assumption of the no omitted confounders, which posits that an omitted variable that confounds the relationships between the antecedent, mediator, and outcome variables cannot exist. One common model in alcohol addiction studies is a nonrandomized latent growth curve mediation model (LGCMM), where the antecedent variable is not randomized, the two covarying mediators are latent intercept and slope modeling longitudinal effect of the repeated measures mediator, and an outcome variable that measures alcohol use. An important gap in the literature is lack of sensitivity analysis techniques to assess the effect of the violation of the no omitted confou…

Psychosocial Factors and Chronic Illness as Predictors for Anxiety and Depression in Adolescence
2020
Adolescence is a challenging time when emotional difficulties often arise. Self-esteem, good relationships with peers, and emotional competences can buffer the effects of these difficulties. The difficulties can be even greater when coupled with the presence of a chronic physical illness (CD). Our goal is to analyze psychosocial factors and CD as predictors for anxiety and depression. It was compared the results of structural equation models (SEM) with models based on qualitative comparative analysis (QCA) to analyze the possible influence of these variables on levels of anxiety-depression in adolescents with and without CD. The sample consisted of 681 adolescents, between 12 and 16 years o…
Toward an update of the structural model in Italian submerged areas: contributions from the EMODnet Geology Project
2016
The European Marine Observation and Data Network (EMODNet) Project aims at the collection of as many existing data as possible on European Seas to be represented on digital maps at the 1:250,000 scale, accessible via web through a dedicated portal. It is articulated into different Lots concerning Bathymetry, Geology, Biology, Chemistry, Physics, Physical Habitats, Human activities. The Geology Lot is realized by a Consortium in which the Geological Survey of Italy is partner. EMODnet Geology requires the compilation of a number of layers subdivided into Work Packages (WP), referring to seafloor sediments grainsize, sedimentation rates, Quaternary geology, pre-Quaternary geology and stratigr…
Procedure for Safety Assessment and BIM Modelling of an Historical Complex Structure through a Macroelement Approach: The Building “Molino-Pastificio…
2022
The structural assessment of existing historical structures is a complex task due to the inner main difficulty in making up reliable models for structural analysis, able to include mechanical and geometrical nonlinearities, existing damage, complex configurations and arrangements of materials. This task becomes more difficult in mixed RC-masonry structures, which structural modelling can be particularly tough due to the different connections and interactions between structural members and materials. This paper presents the case study of a multi-storey mixed Reinforced Concrete (RC)- masonry historical structure, namely the former mill “Molino-Pastificio Soresi” building, located in Partinic…
Un balance de la modernización autonómica y las relaciones intergubernamentales
2015
International audience; This article contains an overview of the modernization of the regional administrations since its inception until present. We distinguish roughly four modernizing cycles: the first is mainly identified with the search for legitimacy and survival of the regional administrations. The second is inspired by the New Public Management (NPM) and the emergence of a post-burocratic paradigm that enables the development of new methodologies. The third is characterized by the primacy of e-administration and quality policies applied to public services. Finally, the last cycle poses antagonistic tendencies, according to the outbreak of the current economic crisis.; En este artícul…

Design, synthesis and structure-activity relationship of 2-(3',4',5'-trimethoxybenzoyl)-benzo[b]furan derivatives as a novel class of inhibitors of t…
2009
The biological importance of microtubules in mitosis and cell division makes them an interesting target for the development of anticancer agents. Small molecules such as benzo[b]furans are attractive as inhibitors of tubulin polymerization. Thus, a new class of inhibitors of tubulin polymerization based on the 2-(3′,4′,5′-trimethoxybenzoyl)-benzo[b]furan molecular skeleton, with electron-donating (Me, OMe or OH) or electron-withdrawing (F, Cl and Br) substituents on the benzene ring, was synthesized and evaluated for antiproliferative activity, inhibition of tubulin polymerization and cell cycle effects. Adding a methyl group at the C-3 position resulted in increased activity. The most prom…
Modelling the evolution of periodicity in the periodical cicadas
2018
Background: Periodical cicadas (Magicicada spp.) have a life cycle that ends with the entire underground nymph population exhibiting a synchronized mass emergence to mate above ground. Previous studies have hypothesized that the periodical cicadas evolved from non-periodical cicadas by switching from a life-cycle length determined by body size to one determined by age. Questions: When can a mutation coding for fixed life-cycle length invade a resident population in which life-cycle length is variable? What determines the length of the fixed cycle? Methods: Numerical analysis of a mathematical model and simulations of an individual-based model. Results: If there is a sufficiently strong pred…

2015
Anželika Ļitova Ceļojumu žanra specifika mūsdienu krievu literatūrā (2009-2014): maģistra darbs. – Rīga, 2015. – 80 lpp. Darbs ir veltīts ceļojumu žanra īpatnības pētijumam mūsdienu krievu literatūrā. Autors, vadoties pēc strukturālās, salīdzināšanas, intertekstualās un iterpretācijas analīzes metodes, atklāj ceļojumu žanra modifikāciju, struktūras elmentu un pazīmju īpatnības. Darbu veido divas sadaļas. Pirma sadaļa ir veltīta ceļojumu žanra noteikšanas un pētījuma problēmu rakstūrojam. Otra sadaļa ir veltīta dažādu autoru literāro darbu analizem, kas ir iekļauti „Krievu ceļotāja vēstules” grāmatu serijā. Pētījums var ieinteresēt filologus, kas nodarbojas ar līdzīgu tēmu.
