MEDIUM-TERM DETERMINANTS OF INTERNATIONAL INVESTMENT POSITIONS: THE ROLE OF STRUCTURAL POLICIES
2012
This paper provides an empirical investigation of the medium-term determinants of international investment positions for a large sample of advanced and emerging economies. In addition to the usually considered drivers of foreign assets and liabilities, the analysis focuses on the role of structural policy indicators. Using cross-section and panel regression techniques the results suggest that structural policy settings are important medium-term drivers of capital flows, having a relatively large impact on gross and net foreign capital positions and on their composition. In particular, the results suggest that certain kinds of structural policy reform could help to narrow global imbalances,…
Nozīmes veidošana attēlos: lingvistiskā un paralingvistiskā perspektīva
2021
Darba mērķis ir izpētīt, kā attēlu nozīmi iespējams interpretēt noteiktā kontekstā. Pētījums reaģē uz galējās interpretācijas problemātiku un ierosina skatīt Čārlza Pīrsa zīmju teoriju kā instrumentu, kas ļauj analizēt nozīmes radīšanas un interpretācijas procesualitāti noteiktas situācijas un kultūras kontekstā. Tiek pētīti četri atšķirīgi attēlu gadījumi (Hilma af Klinta, Sajs Tvomblijs, Gerhards Rihters un Vija Celmiņa), piemērojot mainīgos konteksta lielumus un Pīrsa zīmju klasifikācijas. Vijas Celmiņas intervijas fonētiskā un runātā diskursa analīze liecina, ka mākslinieces runātais teksts var attīstīt uztvērēja priekšzinās…
Additive functionals and push forward measures under Veretennikov's flow
2014
16 pages; In this work, we will be interested in the push forward measure $(\vf_t)_*\gamma$, where $\vf_t$ is defined by the stochastic differential equation \begin{equation*} d\vf_t(x)=dW_t + \ba(\vf_t(x))dt, \quad \vf_0(x)=x\in\mbR^m, \end{equation*} and $\gamma$ is the standard Gaussian measure. We will prove the existence of density under the hypothesis that the divergence $\div(\ba)$ is not a function, but a signed measure belonging to a Kato class; the density will be expressed with help of the additive functional associated to $\div(\ba)$.
Deep Learning for Classifying Physical Activities from Accelerometer Data
2021
Physical inactivity increases the risk of many adverse health conditions, including the world’s major non-communicable diseases, such as coronary heart disease, type 2 diabetes, and breast and colon cancers, shortening life expectancy. There are minimal medical care and personal trainers’ methods to monitor a patient’s actual physical activity types. To improve activity monitoring, we propose an artificial-intelligence-based approach to classify the physical movement activity patterns. In more detail, we employ two deep learning (DL) methods, namely a deep feed-forward neural network (DNN) and a deep recurrent neural network (RNN) for this purpose. We evaluate the proposed models on two phy…
Genesi geometrica delle volte centriche
1996
Un'analisi completa degli organismi voltati comporta lo studio delle molteplici componenti necessarie alla loro definizione: configurazione geometrica, sistema costruttivo, area storico-geografica di appartenenza, interpretazioni Stilistiche. L’obiettivo di questo studio è indirizzato all' analisi delle volte continue su pianta centrica definibili attraverso le leggi della geometria euclidea. L’indagine si pone all'interno dei confini relativi alla loro configurazione geometrica e il criterio adottato, svincolato da classificazioni di carattere tipologico o stilistico, propone l'identificazione di famiglie geometriche in base alla figura del poligono di base dell'impianto. Si può identifica…
Functional classifications and their application in phytoplankton ecology
2015
SUMMARY 1. Ecologists often group organisms based on similar biological traits or on taxonomic criteria. However, the use of taxonomy in ecology has many drawbacks because taxa may include species with very different ecological adaptations. Further, similar characters may evolve independently in different lineages. 2. In this review, we examine the main criteria that have been used in the identification of nine modes of classifying phytoplankton non-taxonomically. These approaches are based purely on morphological and/or structural traits, or on more complex combinations including physiological and ecological features. 3. Different functional approaches have proved able to explain some frac…
Distributed Learning Automata-based S-learning scheme for classification
2019
This paper proposes a novel classifier based on the theory of Learning Automata (LA), reckoned to as PolyLA. The essence of our scheme is to search for a separator in the feature space by imposing an LA-based random walk in a grid system. To each node in the grid, we attach an LA whose actions are the choices of the edges forming a separator. The walk is self-enclosing, and a new random walk is started whenever the walker returns to the starting node forming a closed classification path yielding a many-edged polygon. In our approach, the different LA attached to the different nodes search for a polygon that best encircles and separates each class. Based on the obtained polygons, we perform …
Automatic image-based identification and biomass estimation of invertebrates
2020
1. Understanding how biological communities respond to environmental changes is a key challenge in ecology and ecosystem management. The apparent decline of insect populations necessitates more biomonitoring but the time-consuming sorting and expert-based identification of taxa pose strong limitations on how many insect samples can be processed. In turn, this affects the scale of efforts to map and monitor invertebrate diversity altogether. Given recent advances in computer vision, we propose to enhance the standard human expert-based identification approach involving manual sorting and identification with an automatic image-based technology. 2. We describe a robot-enabled image-based ident…
I sapori dei tatuaggi nell'Amazzonia indigena
2018
Through an analysis of some ethnographic examples (Matis, Akawaio,Guayaki, Cayabi), the chapter shows how in Indigenous Amazonia tattooing was connected in multiple ways to cultural conceptions regarding both the fabrication of the person and the classifications of world components, in which complex systems of correspondence between diverse domains organize people's experience and thought.
Soil interpretation in the context of anthropedogenic transformations and pedotechniques application
2018
Abstract Following a long and vigorous study carried out by the International Committee on Anthropogenic Soils (ICOMANTH), the Soil Taxonomy (ST) classification system recently incorporated a number of changes to include Human-Altered and Human-Transported soils, generally called anthropogenic soils. These changes underwent careful scrutiny as they affect the current classification of existing soil series, and as the proposals and logics are as yet untested against existing data and descriptions. Particular attention was given to the diagnostic characteristics of the anthropogenic soils and to the Subgroups for Human-Altered and Human-Transported soils. In this study, we consider a frequent…
