Lay understanding of the causes of binge drinking in the United Kingdom and Australia: a network diagram approach
2017
Binge drinking is associated with deleterious health, social and economic outcomes. This study explored the lay understanding of the causes of binge drinking in members of the general public in the United Kingdom and Australia. Participants in the United Kingdom (N = 133) and Australia (N = 102) completed a network diagram exercise requiring them to draw causal paths and provide path strength ratings between 12 candidate factors (24-h opening, age, alcohol advertizing, alcohol availability, boredom, drinking culture, income, low cost, parental influence, peer pressure, stress and supermarket discounts) and binge drinking. Results indicated good consistency in paths across samples, although…
Overcommitment as a predictor of effort-reward imbalance: evidence from an 8-year follow-up study.
2016
Objective The effort–reward imbalance (ERI) model includes the personal characteristic of overcommitment (OC) and the job-related characteristics of effort, reward, and ERI, all of which are assumed to play a role in an employee’s health and well-being at work. The aim of the present longitudinal study was to shed more light on the dynamics of the ERI model by investigating the basic hypotheses related to the role of OC in the model, ie, to establish whether an employee’s OC could be a risk factor for an increased experience of high effort, low reward, and high ERI at work. Methods The study was based on 5-wave, 8-year follow-up data collected among Finnish professionals in 2006 (T1, N=747)…
Modeling Radicalization and Violent Extremism
2020
Given public anxiety about radicalization and violent extremism, it is not surprising that these topics have grabbed the attention of so many scholars in recent years. However, some have expressed concern over the fact that only a few studies in this relatively new field contain empirical data or systematic data analysis or develop causal models of the mechanisms generating these phenomena. We believe that computational modeling and simulation techniques can make a significant contribution to this scientific literature and eventually provide new tools for improving policy analysis. Here we briefly describe (1) an integrative theory of violent extremism proposed by Kruglanski and colleagues …
Model development (conceptualisation)
2016
Chapter 2 provided the theoretical background for the development of the conceptual model. In this chapter, firstly, the constructs relevant for the model are conceptualised, and secondly, hypotheses regarding the relationships between those constructs are derived from theoretical considerations.

The intentional stance as structure learning: a computational perspective on mindreading
2015
Recent theories of mindreading explain the recognition of action, intention, and belief of other agents in terms of generative architectures that model the causal relations between observables (e.g., observed movements) and their hidden causes (e.g., action goals and beliefs). Two kinds of probabilistic generative schemes have been proposed in cognitive science and robotics that link to a "theory theory" and "simulation theory" of mindreading, respectively. The former compares perceived actions to optimal plans derived from rationality principles and conceptual theories of others' minds. The latter reuses one's own internal (inverse and forward) models for action execution to perform a look…
Happy Aged People Are All Alike, While Every Unhappy Aged Person Is Unhappy in Its Own Way
2011
Aging of the world’s population represents one of the most remarkable success stories of medicine and of humankind, but it is also a source of various challenges. The aim of the collaborative cross-cultural European study of adult well being (ESAW) is to frame the concept of aging successfully within a causal model that embraces physical health and functional status, cognitive efficacy, material security, social support resources, and life activity. Within the framework of this project, we show here that the degree of heterogeneity among people who view aging in a positive light is significantly lower than the degree of heterogeneity of those who hold a negative perception of aging. We base…
THE FIRM-LEVEL EFFECTS OF SERVICE INNOVATION: A LITERATURE REVIEW
2010
Despite the importance of service innovation, its effects have been given relatively little explicit attention in the extant literature. Instead, researchers often implicitly assume that firm-level service innovation activities result in a number of positive financial and other effects. This paper conducts a systematic review of literature on the firm-level effects of service innovation and attempts to identify and categorize the effects suggested in the literature. The review reveals a considerable number of potential firm-level service innovation effects that have been discussed in extant research. We suggest that they may be divided into five effect categories: (1) business process effec…
Improved Predictability for Foreign Direct Investors by Comprising Different Macroeconomic Levels: A New Model Approach
2020
Foreign direct investments have grown over the last decades which are related to the ongoing globalization process. The current literature shows research works dealing with the topic of influence factors on foreign direct investment (FDI) decisions which may occur during the decision-making process. A new causal model has been developed to get in-depth view on macroeconomic perspective. Motives to do FDI are strongly impacted by macroeconomic factors which may influence upcoming decisions. To be able to understand the impact of the macroeconomic environment on FDI decisions the factors have been diversified and conceptualized, divided into three subgroups of independent latent variables in …
Depressive Symptoms and Alcohol Use are Genetically and Environmentally Correlated Across Adolescence
2010
Depressive symptoms and alcohol use are frequently positively associated during adolescence. This study aimed to assess the heritability of each phenotype across adolescence; to assess potential shared liabilities; to examine changes in the nature of shared liabilities across adolescence; and to investigate potential causal relationships between depressive symptoms and alcohol use. We studied a longitudinally assessed sample of adolescent Finnish twins (N = 1,282) to test hypotheses about genetic and environmental influences on these phenotypes within and across ages, using data from assessments at ages 12, 14, and 17.5 years. The heritability of depressive symptoms is consistent across ado…
