Eye tracking has become a valuable tool for investigating infant looking behavior over the last decades. However, where eye‐tracking methodology and achieving high data quality have received a much attention for adult participants, it is unclear how these results generalize to infant research. This is particularly important as infants behave different from adults in front of the eye tracker. In this study, we investigated whether eye physiology, positioning, and infant behavior affect measures of eye‐tracking data quality: accuracy, precision, and data loss. We report that accuracy and precision are lower, and more data loss occurs for infants with bluish eye color compared to infants with brownish eye color. Moreover, accuracy was lower for infants positioned in a high chair or in the parents' lap compared to infants positioned in a baby seat. Finally, precision decreased and data loss increased as a function of time. We highlight the importance of data quality when comparing multiple groups, as differences in data quality can affect eye‐tracking measures. In addition, we investigate how two different measures to quantify infant movement influence eye‐tracker data quality. These findings might help researchers with data collection and help manufacturers develop better eye‐tracking systems for infants. 相似文献

People with disabilities are consistently found to face considerable difficulties in the labour market. In this study we investigated whether their earnings and income trajectories are more adversely affected in case of involuntary job loss. Earnings of those with and without disabilities began to diverge already several years prior to job loss because of larger incidence of sickness. Following job loss much more job losers with disabilities became disability retirees resulting in a considerable and seemingly permanent earnings differential. However, larger uptake of public social insurances among job losers with disabilities resulted in a much smaller income differential. 相似文献

In recent years, the situation of e-commerce in Germany especially in the retail sector has not only been characterized by a sustained growth in sales but also by an increase in deficits in payment. Companies considering a general exclusion of risky payment methods to be suboptimal are challenged by an adequate assessment of their prospective customers’ risk of payment default. Thereby, inability and unwillingness to pay has to be considered as possible reasons on a transactional basis and in real-time. This paper presents a new approach combining common methods for risk identification and assessment. Case studies show that a more sophisticated risk control can be achieved by applying the approach presented. 相似文献

This paper presents an integrated 21-equation model of how marriage, family, and population conditions, as indexed by macro social indicators, affect each other and are affected by other social, demographic, and economic forces. An opportunity structures theoretical paradigm is applied to the specification of dynamic structural equations for determining changes (both trends and cyclical fluctuations) in marriage formation and dissolution, family and household composition, fertility, mortality, population growth, and population distribution. The equations are estimated on annual national data for the United States during the post-World War II years 1947 to 1972, and then they are used to make conditional forecasts of the values of some of the endogenous variables for 1973 and 1974. It is found that the equations fit the observed data well, lack demonstrable autocorrelation of disturbances, and forecast the 1973 and 1974 values usually with less than 2% error. Strategies are sketched for further refining some of the equations, and it is suggested that this model should be integrated into a larger societal model in order to estimate some of the effects of changes in demographic phenomena on other social conditions. 相似文献

Building the therapeutic alliance is a creative process and is a central issue for all age groups. In the absence of an alliance, there can be no therapy. The alliance contains many primitive sources for collaboration with the therapist. It is a combination of both rational and irrational elements. The therapist's awareness of developmental issues and defense mechanisms are utilized to guide one along the pathway of productive therapy. In addition, the unique psychodynamic factors are considered when working with children and adolescents. The clinical examples distinguish pitfalls which are destructive and could be avoided, in contrast with understanding and responding appropriately to the verbal and nonverbal communications of the young patient.This paper was presented to the International Conference for the Advancement of Private Practice of Clinical Social Work, Rio de Janeiro, Brazil, August 1987.
