BACKGROUND Health Related Quality of Life (HRQoL) is an important outcome measure in health economic evaluation that guides health resource allocations. Population norms for HRQoL are an essential ingredient in health economics and in the evaluation of population health. The aim of this study was to produce EQ-5D-3L-derived population norms for Sri Lanka. METHOD A population sample (n =  780)...

We estimate the essential norm of a weighted composition operator relatively to the class of Dunford-Pettis operators or the class of weakly compact operators, on the space H∞ of Dirichlet series. As particular cases, we obtain the precise value of the generalized essential norm of a composition operator and of a multiplication operator.

Let φ(z) = (φ1(z), · · · , φn(z)) be a holomorphic self-map of Bn and ψ(z) a holomorphic function on Bn, and H(Bn) the class of all holomorphic functions on Bn, where Bn is the unit ball of C , the weight composition operator Wψ,φ is defined by Wψ,φ = ψf(φ) for f ∈ H(Bn). In this paper we estimate the essential norm for the weighted composition operator Wψ,φ acting from the Hardy space H to H (...

Let Un be the unit polydisc of Cn and φ = (φ1, . . . ,φn) a holomorphic self-map of Un. p(Un), p 0 (U n), and p 0∗(U n) denote the p-Bloch space, little p-Bloch space, and little star p-Bloch space in the unit polydisc Un, respectively, where p,q > 0. This paper gives the estimates of the essential norms of bounded composition operators Cφ induced by φ between p(Un) ( p 0 (U n) or p 0∗(U n)) an...

Mi~ed sensitivity optimization was considered! by Kwakernaak [9]. Francis et al. [5,4,6] gave various characterizations of the problem, e.g., in terms of the distance from [0 w] to [vM]H °°, where W, M, V, are in H = and M is inner. Jonckheere and Verma [7,12] described the problem in terms of the norm of the Hankel-Toeplitz operator displayed in (1) (below). Implicit methods of minimization, e...

A child's growth achievement is a useful indicator of his well-being and nutritional status. This can easily be assessed by comparing his growth parameters such as weight, length and head ci rcumference, with norms or standards derived from a relatively healthy population of genetically similar children. Such standards are essential to professionals working with children, for example paediatric...

To develop realistic computational cognitive models of human decision making, it is essential to incorporate various traditionally non-cognitive but critically important soft factors into the model development, such as cultural biases, intuition, emotion, social norms, etc. In this paper we attempt to explore human cognitive-affective interactions in strategic thinking through a neurocomputatio...

Background: Knowledge sharing in university environments is essential and students' behavior in this field is based on their beliefs, norms and attitudes. Theory of planned behavior is one of the most prestigious behavior prediction models that can be used to examine the ideas, values, and attitudes in the context of knowledge sharing behavior. Considering the role of academics...
