Human–human communication studies have suggested that within communicative interactions, individuals acknowledge each other as intentional agents and adjust their emotion nonverbal behavior according to the other. This process has been defined as emotional attunement. In this study, we examine the emotional attunement process in the context of affective human–computer interactions. To this purpose, participants were exposed to one of two conditions. In one case, they played with a computer that simulated understanding of their emotional reactions while guiding them across four different game-like activities; in the other, the computer guided participants across the activities without mentioning any ability to understand emotional responses. Face movements, gaze direction, posture, vocal behavior, electrocardiogram and electrodermal activity were simultaneously recorded during the experimental sessions. Results showed that if participants were aware of interacting with an agent able to recognize their emotions, they reported that the computer was able to “understand” them and showed a higher number of nonverbal behaviors during the most interactive activity. The implications are discussed. 相似文献

ABSTRACTThis study describes the process of developing and validating the Sexual Prejudice in Sport Scale (SPSS), which is a multidimensional instrument developed to assess attitudes toward lesbians and gay men (LG) in sports. The authors conducted two studies: first, to establish the factor structure of the SPSS on 297 heterosexual athletes; and, second, to test the reliability and validity of the resulting 19-item scale on a sample of 311 heterosexual and 160 LG athletes. Exploratory factor analysis of an initial item pool yielded three factors: open rejection, which assesses the blatant prejudice expressed toward LG people; denial of visibility, which evaluates attitude toward the coming out of LG people; and gendering performance, which corresponds to gender stereotypes about performance/skills of LG people. A confirmatory factor analysis was conducted to assess the stability of the SPSS. The authors documented internal consistency, test-retest stability, and convergent/divergent validity. Implications and directions for future research are discussed. 相似文献

Motivated by an interest in investigating factors associated with poverty risks in Italy, our study provides insight into the relationship between various socio-economic, demographic, and behavioural variables and a new measure of the economic inadequacy of households. We propose that a household is in a condition of economic inadequacy when it simultaneously has difficulty making ends meet and is in arrears with payments of commitments for more than 90 days. To analyse the determinants of economic inadequacy, we use cross-sectional microdata collected through a structured questionnaire from a 2012 survey of household income and wealth conducted by the Bank of Italy. The results of the analysis show that the probability of economic inadequacy for Italian households is higher when the household is located in regions in southern Italy, has a low equivalent income, registers a decrease in income compared with that of a normal year, has a low liquidity ratio, pays rent for the house of residence, is over-indebted, is indebted to friends and relatives, and has an unhappy and impatient household head. We also propose constructing a composite indicator at the regional level that combines the percentage of households in relative poverty, as measured by the Italian National Institute of Statistics, and the percentage of households that we identify as existing in a condition of economic inadequacy. The composite indicator allows us to take into account some aspects of household living conditions that are not included in the measure of relative poverty. 相似文献

This article explores the interaction between consumption externalities and limited asset market participation (LAMP) in the standard New‐Keynesian model. We assess the performance of simple Taylor‐type interest rate rules with respect to (a) equilibrium determinacy, (b) the model's ability to simultaneously generate output and inflation volatility similar to the pre‐Volcker era, and (c) the model's response to a technology shock. We find that when individual preferences are affected by average household consumption (Aggregate Consumption Externality), stronger externalities increase the range of LAMP for which multiple equilibria arise even if the policy rule satisfies the Taylor principle. The interaction of LAMP and externalities can generate vast inflation/output relative volatility in line with the one observed in the data in the 1970s. According to our analysis, consumption externalities also affect the responses of endogenous variables to total factor productivity shocks. (JEL E4, E5) 相似文献

This paper focuses on biotechnologies and biotech companies. Our aim is to develop a model for assessing the openness degree of knowledge governance strategies, applying it to the biotech firms. Biotech production is described as an emerging meta-industry in the global economy, fostering through new products, many socio-economic fields. Its main features are: a close relationship among knowledge, innovation and competitiveness; the need for collaborative research; the importance of small firms. Our paper begins with a brief characterization of the biotech meta-sector. We then review the literature regarding the advantages and disadvantages of ??wholly proprietary?? versus ??wholly open?? knowledge strategies. Next we propose a model and report the main results of its application to biotech companies in Italy. In conclusion, we evaluate the degree of openness of the company knowledge strategies based upon empirical evidence from our research in the field. 相似文献

Small area estimators are often based on linear mixed models under the assumption that relationships among variables are stationary across the area of interest (Fay–Herriot models). This hypothesis is patently violated when the population is divided into heterogeneous latent subgroups. In this paper we propose a local Fay–Herriot model assisted by a Simulated Annealing algorithm to identify the latent subgroups of small areas. The value minimized through the Simulated Annealing algorithm is the sum of the estimated mean squared error (MSE) of the small area estimates. The technique is employed for small area estimates of erosion on agricultural land within the Rathbun Lake Watershed (IA, USA). The results are promising and show that introducing local stationarity in a small area model may lead to useful improvements in the performance of the estimators. 相似文献

In this paper we investigate how age affects the self-reported level of life satisfaction among the elderly in Europe. By
using a vignette approach, we find evidence that age influences life satisfaction through two counterbalancing channels. On
the one hand, controlling for the effects of all other variables, the own perceived level of life satisfaction increases with
age. On the other hand, given the same true level of life satisfaction, older respondents are more likely to rank themselves
as “dissatisfied” with their life than younger individuals. Detrimental health conditions and physical limitations play a
crucial role in explaining scale biases in the reporting style of older individuals. 相似文献

We characterize optimal consumption, capital, and population growth of a production economy under critical-level utilitarianism.
First, we show that neither classical utilitarianism nor average utilitarianism can avoid a corner solution for the population
growth rate, in that under the former, population grows at the maximum speed (the so-called repugnant conclusion) while under
the latter, it grows at the minimum. Second, we show that critical level utilitarianism yields an interior solution for the
population growth rate provided the critical level belongs to a positive, open interval. Finally, we characterize the transition
to the steady state and perform comparative dynamics analysis. 相似文献

We address the problem of robust inference about the stress–strength reliability parameter R = P(X < Y), where X and Y are taken to be independent random variables. Indeed, although classical likelihood based procedures for inference on R are available, it is well-known that they can be badly affected by mild departures from model assumptions, regarding both
stress and strength data. The proposed robust method relies on the theory of bounded influence M-estimators. We obtain large-sample test statistics with the standard asymptotic distribution by means of delta-method asymptotics.
The finite sample behavior of these tests is investigated by some numerical studies, when both X and Y are independent exponential or normal random variables. An illustrative application in a regression setting is also discussed. 相似文献
