Do-search -- a tool for causal inference and study design with multiple data sources
2020
Epidemiologic evidence is based on multiple data sources including clinical trials, cohort studies, surveys, registries, and expert opinions. Merging information from different sources opens up new possibilities for the estimation of causal effects. We show how causal effects can be identified and estimated by combining experiments and observations in real and realistic scenarios. As a new tool, we present do-search, a recently developed algorithmic approach that can determine the identifiability of a causal effect. The approach is based on do-calculus, and it can utilize data with nontrivial missing data and selection bias mechanisms. When the effect is identifiable, do-search outputs an i…
Chances and Challenges of Computational Data Gathering and Analysis
2015
Digital and social media and large available data-sets generate various new possibilities and challenges for conducting research focused on perpetually developing online news ecosystems. This paper presents a novel computational technique for gathering and processing large quantities of data from Facebook. We demonstrate how to use this technique for detecting and analysing issue-attention cycles and news flows in Facebook groups and pages. Although the paper concentrates on a Finnish Facebook group as a case study, the demonstrated method can be used for gathering and analysing large sets of data from various social network sites and national contexts. The paper also discusses Facebook pla…
A Mobile-Assisted Working Model for Supporting Daily Family Life
2015
Despite rapid technological development, very few new technology-assisted tools have been developed specifically for use in family services. This article describes a new, mobile-assisted working model designed to enhance the quality of daily family life. The model has its origins in the existing research on daily family life and on the diary method, which has been widely used in data collection in family research. The model provides support for the daily life of client families in the intervals between meetings with family counselors via the use of text messages. The pilot study explored family members’ and family counselors’ experiences of using the model. Data on 26 parents and four chil…
Risk Taking by Banks in the Transition Countries
2007
The banking sectors of the transition countries have progressed remarkably in the last 15 years. In fact, banking in most transition countries has largely shaken off the traumas of the transition era. At the start of the 21st century banks in these countries look very much like banks elsewhere. That is, they are by no means problem free but they are struggling with the same issues as banks in other emerging market countries. There have been a surprisingly large number of studies that have told us about the performance of these banks but we know very little about their risk taking behaviour and how the banking environment influences it.
Financial Behaviour Under Economic Strain in Different Age Groups: Predictors and Change Across 20 Years
2021
AbstractThe present study examined the multiple micro- and macro-level factors that affect individuals’ financial behaviour under economic strain. The following sociodemographic and economic factors that predict financial behaviour were analysed: age group, year of data gathering, and attitudes towards consumption (economical, deprived, and hedonistic). Subjective financial situations and demographic characteristics were controlled for. Finnish time series data that consisted of five cross-sectional nationally representative surveys were used (n = 10 043). The analyses revealed four types of financial behaviour: cutting expenses, borrowing, increasing income, and gambling. Young adults aged…
Improving Serendipity and Accuracy in Cross-Domain Recommender Systems
2017
Cross-domain recommender systems use information from source domains to improve recommendations in a target domain, where the term domain refers to a set of items that share attributes and/or user ratings. Most works on this topic focus on accuracy but disregard other properties of recommender systems. In this paper, we attempt to improve serendipity and accuracy in the target domain with datasets from source domains. Due to the lack of publicly available datasets, we collect datasets from two domains related to music, involving user ratings and item attributes. We then conduct experiments using collaborative filtering and content-based filtering approaches for the purpose of validation. Ac…
Forest types for biodiversity assessment at regional level: the case study of Sicily (Italy)
2007
Within Europe the question of plant coenosis is attracting growing interest. The quality and quantity of collected information on forest resources at a global level largely depends on the capacity to collect and analyse data at national and sub-national scale in a way compatible with those at global or continental levels. In Italy the acceptance of all the international agreements and protocols on the protection of the environment and management of natural resources, requires a standardization of collected information and statistics, with the aim to produce homogeneous and integrative data at global level. This need is reflected in the following points: (1) the adoption of a classification …
Is R&D Enough to Take Advantage From External Knowledge?: Focusing on Coordination Mechanisms
2014
The purpose of this paper is to analyze the role of research and development (R&D) and coordination mechanisms (such as decentralization in decision-making and formalization of organizational processes) in the transformation of external knowledge into innovation results. We use survey data for performing standard ordinary least squares regressions in a representative sample of firms from the Spanish Ceramic Tile Industry. The results suggest that R&D is an important moderator influencing the relationship between acquiring external knowledge and innovation outcomes. Second, formalization tends to have a detrimental effect in the transformation of external knowledge into innovation outputs. T…
Deux plaidoyers mystiques en faveur du « no pensar nada » : le Troisième Abécédaire spirituel (1527) et la Loi d'amour (1530) de Francisco de Osuna
2017
Two mystical pleas for the «no pensar nada»: the Third Spiritual alphabet (1527) and the Law of love (1530) by Francisco de Osuna A mystic principle rooted in negative theology (from Pseudo-Dionysius the Areopagite to Saint John of the Cross), the « no pensar nada » ("thinking-nothing") was strongly defended by Franciscan preacher and spiritual guide of the « Recollection », Francisco de Osuna, in a context of spiritual polemics marked by the condemnation of Toledo's « Alumbrados » ("the Illuminated") in 1525. Despite the Holy Office's strong pressure, and the threat of censorship, Osuna openly advocated the « thinking-nothing » principle in a chapter of the Third Spiritual Alphabet (1527),…
A new system for the representation of places hit by disasters
2010
This paper analyses a new system for data collection and management after a disaster. In particular, the system enables to represent what exists in a place, and to visualize the preceding state, in a synoptic vision before and after the event; and also enables the consultation of synthetic information, the possibility of connections to internet sites for further in depth analysis and then the possibility of archiving and retrieving data through researching specific items. This is carried out in a simple and quick way, utilizing a portable device. The obtained product is consultable on site, or otherwise memorized and archived. Because of all these functions, it could be a useful instrument …
