The aim of this study was to investigate if children's early responsiveness toward social partners is developmentally related to their growing concept of self, as reflected in their mirror self-recognition (MSR) and delayed self-recognition (DSR). Thus, a longitudinal study assessed infants' responsiveness (e.g., smiling, gaze) toward social partners during the still-face (SF) task and a social...

conclusions graft failure is more likely to occur in patients with higher serum creatinine levels. results there was a positive association between the serum creatinine level and graft failure (hr = 5.13, p < 0.001). a one unit increase in the serum creatinine level suggests an increased risk of graft failure of up to 5.13 times. the serum creatinine level significantly decreased over time (95%...

Clinical studies often collect longitudinal and time-to-event data for each subject. Joint modeling is a powerful methodology evaluating the association between these data. The existing models, however, have not sufficiently addressed problem of missing data, which are commonly encountered in studies. In this paper, we introduce novel joint model with shared random effects incomplete Our propos...

INTRODUCTION Population ageing is a welcome testament to improvements in the social, economic and health circumstances over the life course. However, these successes necessitate that we understand more about the pathways of ageing to plan and cost our health and social care services, to support our ageing population to live healthier for longer and to make adequate provisions for retirement. Lo...

Mediation models are used to describe the mechanism(s) by which one variable influences another. These models can be useful in developmental research to explicate the relationship between variables, developmental processes, or combinations of variables and processes. In this article we describe aspects of mediation effects specific to developmental research. We focus on three central issues in ...
