This study investigated the mechanisms by which experiences of poverty influence the trajectory of conduct problems among preschool children. Drawing on two theoretical perspectives, we focused on family stress (stress and harsh discipline) and investment variables (educational investment, nutrition, and cognitive ability) as key mediators. Structural equation modeling techniques with prospecti...

In this paper, we show that the Advanced Encryption Standard (AES) cryptosystem can be utilized as an error-correcting code to obtain reliability over noisy communication and data systems. Specifically, by composing a simple padding followed encrypting with AES, achieve performance similar random codes. We conduct empirical comparison between our AES-based error correction approach, Random Line...

In December 2007 and January 2008 a survey on ethical aspects of ICT was executed. The aim was to assess the ethical behaviour of ICTprofessionals in Belgium and thus opening a discussion on the need for an ethical code of conduct in the ICTmanagement domain. Respondents were asked to give their opinion on the ethical impact of nine ICT related cases. The target group involved in the survey con...

In December 2007 and January 2008 a survey on ethical aspects of ICT was executed. The aim was to assess the ethical behaviour of ICT-professionals in Belgium and thus opening a discussion on the need for an ethical code of conduct in the ICT-management domain. Respondents were asked to give their opinion on the ethical impact of nine ICT related cases. The target group involved in the survey c...

we present an approach to design of fault tolerant computing systems. in this paper, a technique is employed that enable the combination of several codes, in order to obtain flexibility in the design of error correcting codes. code combining techniques are very effective, which one of these codes are turbo codes. the algorithm-based fault tolerance techniques that to detect errors rely on the c...

We conduct an analysis of ideal error correcting codes for randomized unitary channels determined by two unitary error operators – what we call “binary unitary channels” – on multipartite quantum systems. In a wide variety of cases we give a complete description of the code structure for such channels. Specifically, we find a practical geometric technique to determine the existence of codes of ...

the main objective of this paper is to evaluate the effect of r&d on profitability of high -tech industries with new evidence from the iranian industries carrying four- digit codes. the structure- conduct- performance (scp) paradigm, which is relatively well known in industrial economics and in organization management, provides the theoretical construct that guides our empirical model formu...
