Abstract

Purpose

This paper aims to present a computational approach which – setting off from measures obtained by using an overdrilling method – determines, automatically and accurately, stress changes undergone in terrain as a consequence of human activity.

Design/methodology/approach

The method presented uses the data from three boreholes and the elasticity theory to represent a numerical system whose resolution allows determining the stress state in a particular point. Since the system obtained is over‐dimensioned, the Levenberg‐Marquardt minimization method has been used in order to minimize errors. This paper details the analysis carried out in order to develop the computational method.

Findings

This paper provides the algorithm for determining inner stresses in a particular point of a rock mass. Besides, a method to verify obtained results is presented, including its computational encoding in C#. Furthermore, the developed methods have been integrated in a computer tool which presents the results in a graphic environment.

Research limitations/implications

The algorithms presented are applicable when using an overdrilling method to measure stresses.

Practical implications

A reliable determination of global stress state demands the use of any method that is numerically difficult to use. Thus, in practice, it is of great importance to dispose of some reliable automatic tool to calculate stress state.

Originality/value

Accuracy in the results obtained with the tool, together with the simplicity of its interface, involves a certain advantage regarding the use of a general‐scope commercial tool, since it allows – without being necessary to be an expert user – quickly obtaining results within the analysed working area.

Abstract

Purpose

This paper aims to carry out a systematic review based on the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines to assess the adherence to the Mediterranean dietary pattern (MDP) in workers.

Design/methodology/approach

Three electronic databases were searched up to March 2022. The population was restricted to adults, workers in any professional area, without special diets and no specific health conditions. Their adherence to the MDP was assessed by any a priori method/instrument. Two reviewers independently applied the eligibility criteria and performed the data extraction from each study included. In case of disagreement, a third reviewer was consulted.

Findings

Of the 590 studies found, 46 were included. Most of the studies were carried out in Europe, between the years 2019 and 2022 and were cross-sectional studies. The minimum sample size was 38, and the maximum was 1,74,638 participants. Most studies included both males and females; six included only females and nine only males. The three most prevalent types of workers under study were health professionals, factory workers and firefighters. The most used method for assessing adherence to the MDP was the Mediterranean diet score. Overall, workers showed low or moderate adherence to the MDP.

Originality/value

This systematic review conducted to assess the adherence to the MDP in workers displays an urgent need to improve diet quality in the workplaces.

Abstract

Purpose

Aggression is an undesirable behavior that assaults traditions norms, morals and standards of ethics practiced in society. To address the scarceness of identification tools and for evidence-based interventions in Pakistan, the purpose of this study is to determine the extent to which aggression is prevalent in Pakistan’s people by newly developed self-reported questionnaires in the Urdu language designed after reviewing the cultural and social perspectives of the society.

Design/methodology/approach

The research design was based on principles of scale development followed by exploratory and confirmatory factor analysis. A subject matter expert panel technique was adopted where educationists from diversified backgrounds helped to generate items and to establish content validity.

Findings

The three-factor construct has been supported by factor analysis. These analyzes identified aggression measures in terms of direct aggression, displaced aggression and indirect aggression. The model has established inner consistency, reliability and validity. Furthermore, the impact of age and gender on different forms of aggression was explored and discussed.

Originality/value

Aggression is a distinctive trait of many psychiatric disturbances. To undertake the dearth of identification tools and for evidence-based interventions in Pakistan, it was necessary to develop a tool for identification to address aggression issues among common people. This research is devised to develop a self-reported questionnaire in the Urdu language keeping cultural and social perspectives of society.
