This study investigates changes in the mental and physical health of carers compared to non-carers over 10 years in a sample of New Zealanders aged 54–70. Mental health increased slightly over time for all participants but there was no difference in trajectory change based on carer status except for those who stopped caring. No significant differences in physical health or differences in trajectory change for physical health across time based on caregiver status were found. Results provide some support for a health selection bias into caring and the adaptation hypothesis of caring across time.

"Making use of a modi ed Hadamard product or convolution of harmonic functions with varying arguments, combined with an integral operator, we study when these functions belong to a given class. Following an idea of U. Bednarz and J. Sokol we de ne the order of convolution consistence of three classes of functions and determine it for certain classes of harmonic functions with varying arguments de ned using a convolution operator."

In the present paper, we introduce and study two new subclasses of analytic and $m$-fold symmetric bi-univalent functions defined in the open unit disk $U$. Furthermore, for functions in each of the subclasses introduced here, we obtain upper bounds for the initial coefficients $\left| a_{m+1}\right|$ and $\left| a_{2m+1}\right|$. Also, we indicate certain special cases for our results.
