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…
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 …
Exploring social media network landscape of post-Soviet space
2019
The “post-Soviet space” consists of countries with a substantial fraction of the world’s population; however, unlike many other regions, its social media network landscape is still somewhat under-explored. This paper aims at filling this gap. To this purpose, we use anonymized data on user friendships at VK.com (also known as VKontakte and, informally, as “Russian Facebook”), which is the largest and most popular social media portal in the post-Soviet space with hundreds of millions of user accounts. Using the VK network snapshots from October 2015 to December 2016, we conduct a “multiscale” empirical study of this network by considering conn…
Revealing Hidden Curvilinear Relations Between Work Engagement and Its Predictors: Demonstrating the Added Value of Generalized Additive Model (GAM)
2014
Previous studies measuring different aspects of the quality of life have, as a rule, presumed linear relationships between a dependent variable and its predictors. This article utilizes non-parametric statistical methodology to explore curvilinear relations between work engagement and its main predictors: job demands, job control and social support. Firstly, the study examines what additional information non-linear modeling can reveal regarding the relationship between work engagement and the three predictors in question. Secondly, the article compares the explanatory power of non-linear and linear modeling with regard to work engagement. The generalized additive model (GAM), that makes pos…
How Multiple Party Identifications Shape the Voters' Political World
2013
Despite being part of the original concept by Campbell et al. (1954, 1960), multiple party identifications are rarely analyzed as most studies use single items that do not allow to identify multiple identifications. I am able to overcome these flaws by using current German survey data. My findings show that considerably shares of the sample hold multiple party identifications. These identifications often have a notable impact on evaluations, attitudes and behavior when compared to single party identification.
The advanced use of mobile phones in five European countries
2014
The paper explores the advanced users of mobile phones in Italy, France, Germany, Spain and the UK (EU5 countries) and aims to clarify the social meaning of advanced use. The mobile phone is seen as a strategic tool of social labour, whose capabilities are exploited to a different extent in the five studied countries. The analysis is based on a cross-national survey data collected in 2009 (N = 7,255). First, the results show that there are substantial differences in the advanced use of mobile phone and its predictors in Europe. Generally, only about one third of the studied mobile features are exploited. British and French people are the most advanced users, followed by German, Spanish and …
Campaigns, candidate evaluations, and vote choice: Evidence from German federal election campaigns, 1980–2002
2007
Abstract This article examines the effect of German federal election campaigns on citizens' attitudes toward chancellor candidates. Building on previous research, it puts forward three hypotheses tested using survey data gathered during seven German federal election campaigns. The results confirm that campaigns polarize the voters' perception of the chancellor candidates. During campaigns, voters also bring their opinions about candidates into line with their partisan attitudes. Moreover, during three campaigns candidate preferences become increasingly powerful predictors of vote choice. The findings also suggest that election-specific factors condition campaign effects. The paper concludes…
