For a C2 function u and an elliptic operator L, we prove a quantitative estimate for the derivative du in terms of local bounds on u and Lu. An integral version of this estimate is then used to derive a condition for the zero-mean value property of Δu. An extension to differential forms is also given. Our approach is probabilistic and could easily be adapted to other settings. [less ▲]

We develop a variational theory of geodesics for the canonical variation of the metric of a totally geodesic foliation. As a consequence, we obtain comparison theorems for the horizontal and vertical Laplacians. In the case of Sasakian foliations, we show that sharp horizontal and vertical comparison theorems for the sub-Riemannian distance may be obtained as a limit of horizontal and vertical comparison theorems for the Riemannian distances approximations.

Usage-based statistical testing employs knowledge about the actual or anticipated usage profile of the system under test for estimating system reliability. For many systems, usage-based statistical testing involves generating synthetic test data. Such data must possess the same statistical characteristics as the actual data that the system will process during operation. Synthetic test data must further satisfy any logical validity constraints that the actual data is subject to. Targeting data-intensive systems, we propose an approach for generating synthetic test data that is both statistically representative and logically valid. The approach works by first generating a data sample that meets the desired statistical characteristics, without taking into account the logical constraints. Subsequently, the approach tweaks the generated sample to fix any logical constraint violations. The tweaking process is iterative and continuously guided toward achieving the desired statistical characteristics. We report on a realistic evaluation of the approach, where we generate a synthetic population of citizens' records for testing a public administration IT system. Results suggest that our approach is scalable and capable o [less ▲]

Caring for a close person involves and impacts several aspects and domains of personal life. A scenario that is often sketched here indicates that caring is physically exhausting, demanding time, leaving no time for leisure, and excluding the carer from further social activities. In this view, caring is strain as it is clearly described by the concept of caregiver burden, and a risk for the psychological and/or physical health of family carers. But caring may also have another side of positive gratification and of fulfilment. To care for another person may represent a meaningful work for both the cared for and the caring person that may also go along with recognition and positive feedback from others. This is the starting point of the present study that addressed a sample of 151 informal carers (n = 111 female) with a mean age of 58 years (SD=14 years) with self-report questionnaire. The measure offered in a first part positive (n=35) and negative aspects (n=23) of caring for a close person and subjects had to rate how much they agree that these aspects are present in their own care giving relationship. Moreover, life satisfaction as well as positive and negative affect were assessed in a second part. Multivariate analyses by factor as well as cluster analyses showed different profiles of gains and losses that were systematically linked to indicators of subjective well-being. Findings will be discussed with respect to their implications for psychosocial intervention in the field of informal care. [less ▲]
