This study aimed to evaluate the urinary excretion of sodium and potassium, and to estimate the main food sources of sodium in Maputo dwellers. A cross-sectional evaluation of a sample of 100 hospital workers was conducted between October 2012 and May 2013. Sodium and potassium urinary excretion was assessed in a 24-h urine sample; creatinine excretion was used to exclude unlikely urine values....

Recent evidence indicates that spending discretionary money with the intention of acquiring life experiences-events that one lives through-makes people happier than spending money with the intention of acquiring material possessions-tangible objects that one obtains and possesses. We propose and show that experiences are more likely to be shared with others, whereas material possessions are mor...

As salt is a potential vehicle for delivering iodine to a population, study on salt intake is important. Many methods have been used to measure iodised-salt intake, but the methods were suspected to be inaccurate. A new method, called a lithium-marker technique, has been considered as suitable and safe; hence it has been proposed as a gold standard for measuring the actual salt intake of an ind...

INTRODUCTION Salt intake increases fluid intake and, consequently, blood pressure (BP) and interdialytic weight gain (IDWG), known as morbi-mortality risk factors for hemodialysis (HD) patients. OBJECTIVE Evaluate salt intake and food sources, as well as its relationship with demographics, clinical and nutritional parameters. METHODS Cross-sectional study with 109 patients (66% women, age =...

In this paper we examine how Discretionary Access Control principles, that have been successfully applied to relational and XML data, can be applied to the Resource Description Framework (RDF) graph data model. The objective being to provide a baseline for the specification of a general authorisation framework for the RDF data model. Towards this end we provide a summary of access control requi...

Utility maximization problems of mixed optimal stopping /control type are considered, which can be solved by reduction to a family of related pure optimal stopping problems. Sufficient conditions for the existence of optimal strategies are provided in the context of continuous-time, Itô process models for complete markets. The mathematical tools used are those of optimal stopping theory, contin...

This paper studies two disclosure regimes when a firm with superior private information must rely on a strategic certifier to disclose credibly its prospects. In the ex ante (ex post) disclosure regime, the firm must decide on whether to hire the certifier before (after) observing the certifier's noisy assessment. Endogenously determined certification fees can actually cause the disclosure prob...

Discretionary Access Control (DAC) systems provide powerful mechanisms for resource management based on the selective distribution of capabilities to selected classes of principals. We study a type-based theory of DAC models for concurrent and distributed systems represented as terms of Cardelli, Ghelli and Gordon’s pi calculus with groups [3]. In our theory, groups play the rôle of principals,...

this study presents empirical evidence concerning the effect of different accounting standard on earnings management. prior studies have shown that accounting standards influence earnings management. tighter accounting standards regime restricts management’s descretion to manipulate accruals, and at the same time, induce more costly real earnings management activities. to investigate this iss...
