    Financial Stress and Marital Quality: The Moderating Influence of Couple Communication

    This study explores the negative relationship between financial stress and marital quality and examines couple communication as a moderator in this relationship. Using a sample of 373 married U.S. couples from the Flourishing Families Project, an Actor-Partner Interdependence Model (APIM) was run to determine the influence of husbands’ and wives’ financial stress on both their own and their partner’s reports of marital quality. Results found negative associations between both actor and partner reports of financial stress and marital quality. Couple communication did not moderate the associations between husbands’ and wives’ financial stress and wives’ marital quality. However, it did moderate the negative associations between both husbands’ and wives’ financial stress and husbands’ marital quality. Specifically, the deleterious relationship of financial stress to marital quality for husbands was significantly less severe when coupled with positive couple communication. Implications for financial therapists and avenues for future research are discussed

    Perceived Family and Partner Support and the Work-Family Interface: A Meta-Analytic Review

    This study employed meta-analytic techniques to elucidate the role of perceived partner and family support in four measures of the work-family interface. We extracted 183 effect sizes from 82 samples and a total of N = 36,226 individuals. We found perceived familial (partner and family) support was negatively associated with work-to-family conflict (r = -.099) and family-to-work conflict (r = -.178). It was positively associated with work-to-family enrichment (r = .173) and family-to-work enrichment (r = .378). Various sample-level moderators were investigated through meta regression and subgroup analyses, including whether the support measure was family or partner focused. Perceived family support showed larger magnitude associations with the two conflict outcome variables than partner support, while there were no significant differences between family and partner support and the two enrichment outcomes. The results suggest that familial support is an essential component of successfully minimizing work-family conflict and maximizing work-family enrichment, and that whether the measure of support is partner or family specific may impact the magnitude of results

    Modeling long-range cross-correlations in two-component ARFIMA and FIARCH processes

    We investigate how simultaneously recorded long-range power-law correlated multi-variate signals cross-correlate. To this end we introduce a two-component ARFIMA stochastic process and a two-component FIARCH process to generate coupled fractal signals with long-range power-law correlations which are at the same time long-range cross-correlated. We study how the degree of cross-correlations between these signals depends on the scaling exponents characterizing the fractal correlations in each signal and on the coupling between the signals. Our findings have relevance when studying parallel outputs of multiple-component of physical, physiological and social systems.Comment: 8 pages, 5 figures, elsart.cl

    Spenders and Tightwads Among Newlyweds: Perceptions of Partner Financial Behaviors and Relational Well-Being

    Finances, and how couples manage their finances, can have important implications for couples’ relational well-being. Using data from 1,585 couples that participated in the CREATE study (a nationally representative dyadic dataset of U.S. newlywed couples), we examined how perceiving one’s spouse as a financial spender (i.e., spending more than they ideally would) or financial tightwad (i.e., spending less than they ideally would) was associated with several measures of relational well-being (i.e., satisfaction, commitment, and power) through actor-partner interdependence structural equation models. Results showed that perceiving one’s partner as a spender was detrimental for both the individual’s and the partner’s marital satisfaction, marital commitment, and marital power. Perceiving one’s partner as a tightwad was detrimental for both the individual’s and the partner’s marital commitment and marital power. The findings suggest that interventions focused on perceptions of financial management behaviors may help strengthen relational well-being among newlyweds

    Emerging properties of financial time series in the “Game of Life”

    Get PDF
    We explore the spatial complexity of Conway’s “Game of Life,” a prototypical cellular automaton by means of a geometrical procedure generating a two-dimensional random walk from a bidimensional lattice with periodical boundaries. The one-dimensional projection of this process is analyzed and it turns out that some of its statistical properties resemble the so-called stylized facts observed in financial time series. The scope and meaning of this result are discussed from the viewpoint of complex systems. In particular, we stress how the supposed peculiarities of financial time series are, often, overrated in their importance

    Nanostructured 3D Constructs Based on Chitosan and Chondroitin Sulphate Multilayers for Cartilage Tissue Engineering

    Nanostructured three-dimensional constructs combining layer-by-layer technology (LbL) and template leaching were processed and evaluated as possible support structures for cartilage tissue engineering. Multilayered constructs were formed by depositing the polyelectrolytes chitosan (CHT) and chondroitin sulphate (CS) on either bidimensional glass surfaces or 3D packet of paraffin spheres. 2D CHT/CS multi-layered constructs proved to support the attachment and proliferation of bovine chondrocytes (BCH). The technology was transposed to 3D level and CHT/CS multi-layered hierarchical scaffolds were retrieved after paraffin leaching. The obtained nanostructured 3D constructs had a high porosity and water uptake capacity of about 300%. Dynamical mechanical analysis (DMA) showed the viscoelastic nature of the scaffolds. Cellular tests were performed with the culture of BCH and multipotent bone marrow derived stromal cells (hMSCs) up to 21 days in chondrogenic differentiation media. Together with scanning electronic microscopy analysis, viability tests and DNA quantification, our results clearly showed that cells attached, proliferated and were metabolically active over the entire scaffold. Cartilaginous extracellular matrix (ECM) formation was further assessed and results showed that GAG secretion occurred indicating the maintenance of the chondrogenic phenotype and the chondrogenic differentiation of hMSCs

    Heterogeneous Agent Models: Two Simple Case Studies

    Full text link
    These notes review two simple heterogeneous agent models in economics and finance. The first is a cobweb model with rational versus naive agents introduced in Brock and Hommes (1997). The second is an asset pricing model with fundamentalists versus technical traders introduced in Brock and Hommes (1998). Agents are boundedly rational and switch between different trading strategies, based upon an evolutionary fitness measure given by realized past profits. Evolutionary switching creates a nonlinearity in the dynamics. Rational routes to randomness, that is, bifurcation routes to complicated dynamical behaviour occur when agents become more sensitive to differences in evolutionary fitness
