In the past decade, corporate firms have globally increasingly adopted social responsibility (CSR) practices; however, so far less is known about how productivity change in presence of socially responsible and undesirable output can be evaluated. This paper develops a framework that integrates CSR dynamic by-production technology which captures transformation multiple inputs into marketed outpu...

A constrained pseudorandom function F : K×X → Y for a family T ⊆ 2X of subsets of X is a function where for any key k ∈ K and set S ∈ T one can efficiently compute a constrained key kS which allows to evaluate F (k, ·) on all inputs x ∈ S, while even given this key, the outputs on all inputs x / ∈ S look random. At Asiacrypt’13 Boneh and Waters gave a construction which supports the most genera...

This paper considers recovering L-dimensional vectors w, and xn, n = 1, . . . , N from their circular convolutions yn = w∗xn. The vector w is assumed to be S-sparse in a known basis that is spread out in the Fourier domain, and each input xn is a member of a known K-dimensional random subspace. We prove that whenever K + S log S . L/ log(LN), the problem can be solved effectively by using only ...

Dinitrogen (N2) fixation (the reduction of atmospheric N2 to ammonium by specialized prokaryotic microbes), represents an important input of fixed nitrogen and contributes significantly to primary productivity in the oceans. Marine N2 fixation was discovered in the North Atlantic Ocean (NA) in the 1960s. Ever since, the NA has been subject to numerous studies that have looked into the diversity...

Given measured data generated by a discrete-time linear system we propose a model consisting of a linear, time-invariant system affected by norm-bounded perturbation. Under mild assumptions, the plants belonging to the resulting uncertain family form a convex set. The approach depends on two key parameters: an a priori given bound of the perturbation, and the input used to generate the data. It...

We study several models for fixed-size packetkell switching (e.g., 53 bytes for asynchronous transfer mode) in wavelength routed optical networks with an emphasis on throughput performance analysis. In particular, we examine the associated trade-offs between functionality and hardware complexity. The basic model here is a two-sided “switch” or sorter. Cells generated at user inputs destined for...

This article contributes to the efficiency literature by defining, in the context of the data envelopment analysis framework, the directional distance function approach for measuring both technical and scale inefficiencies with regard to the use of individual inputs. The input-specific technical and scale inefficiencies are then aggregated in order to calculate the overall inefficiency measures...

In the Map-Reduce programming model for data parallel computation in a cloud environment, the reducer phase is responsible for computing an output key-value pair, given a sequence of input values associated with a particular key. Because of non-determinism in transmitting key-value pairs over the network, the inputs may not arrive at a reducer in a fixed order. This gives rise to the reducer co...

Previous research on human visual perception system had conducted studies on the spatial variation in human visual resolution. Their studies had shown that only the fovea region of human eyes can afford sharp vision with acute visual details. In this paper, we propose an interactive multi-resolution monitor system composed of a multi-resolution input channel and output display. The multi-resolu...

Secure function evaluation (SFE) allows a set of players to compute an arbitrary agreed function of their private inputs, even if an adversary may corrupt some of the players. Secure multi-party computation (MPC) is a generalization allowing to perform an arbitrary on-going (also called reactive or stateful) computation during which players can receive outputs and provide new inputs at intermed...
