Abstract

Purpose

The purpose of this paper is to determine the reason for the discrepancy in estimated and observed damage caused by fragmenting charges in closed environments.

Design/methodology/approach

A series of carefully conducted physical and numerical experiments was conducted. The results were analyzed and compared.

Findings

The analysis shows that for fragmenting charges in closed environments, dust plays a far larger role than previously thought, leading to much lower pressures and damage.

Research limitations/implications

In light of these findings, many assumptions and results for fragmenting charges in closed environments need to be reconsidered.

Practical implications

This implies that for a far larger class of problems than previously estimated it is imperative to take into consideration dust production and its effect on the resulting pressures.

Originality/value

This is the first time such a finding has been reported in this context.

Abstract

Purpose

Poor health-related quality of life (HRQoL) is one of the important issues in the health sector. The purpose of this paper is to investigate the prevalence and socio-economic inequality in poor HRQoL in Tehran city, Iran.

Design/methodology/approach

In total, 562 adults were included in this cross-sectional study. The cluster sampling method was used for data collection from May to June, 2016 in Tehran city, Iran. Data on HRQoL, using EuroQol 5-dimensions questionnaire, and data on socio-economic and demographic variables were gathered. Convenience regression method was performed to measure the concentration index (CI). Decomposition analysis was performed to determine the contribution of variables on socio-economic inequality in poor HRQoL. All analyses were performed by Stata v.14.

Findings

The prevalence of poor HRQoL was 28.3 percent. The value of CI for “poor HRQoL” was −0.299 (95% confidence interval: −0.402 to −0.195). Socio-economic status (SES) was the largest contributor to socio-economic inequality in poor HRQoL (69.44 percent of inequality was explained by SES). Age, obesity and race had a positive contribution to socio-economic inequality in poor HRQoL among the participants. Nonetheless, sex and smoking intensity had a negative contribution to inequality in poor HRQoL.

Originality/value

There is little evidence about the prevalence of poor HRQoL in insured people. This study provided new evidence in this area through the investigation of socio-economic inequality in poor HRQoL and its determinants among people with health insurance in Iran using decomposition analysis.

Abstract

Purpose

Post-partum depression (PPD) is a mood disorder that affects 20-40 per cent of women in their post-delivery period worldwide. The purpose of this paper is to compare dietary intakes of energy, macronutrients, cholesterol, saturated fatty acids (SFAs), mono-unsaturated fatty acids (MUFAs), poly-unsaturated fatty acids (PUFAs), some micronutrients and antioxidants in PPD patients with healthy controls.

Design/methodology/approach

This case-control study was conducted on 163 women in postpartum period (81 PPD and 82 non-PPD) using Edinburgh questionnaire for the diagnosis of PPD. Dietary nutrients intake was assessed using 147-item semi-quantitative food frequency questionnaire (FFQ). Portion sizes of food items were converted to grams per day. Logistic regression models were used to estimate the association between tertiles of dietary intakes with the odds ratio (OR) of PPD.

Findings

According to the fully adjusted model, highest tertile compared to lowest tertile dietary intake of SFAs [OR = 0.01; 95 per cent confidence interval (CI) = 0.00, 0.01, p = 0.001], MUFAs (OR = 0.01; 95 per cent CI = 0.00, 0.02, p < 0.001), total fats (OR = 0.01; 95 per cent CI =0.00, 0.01, p < 0.001) and cholesterol (OR = 0.06 ; 95 per cent CI = 0.01, 0.08, p < 0.001), thiamine (OR = 0.01; 95 per cent CI = 0.00, 0.01, p < 0.001), riboflavin (OR = 0.10; 95 per cent CI = 0.02, 0.39, p < 0.001), pyridoxine (OR = 0.03; 95 per cent CI =0.01, 0.32, p < 0.001), folate (OR = 0.01; 95 per cent CI = 0.00, 0.01, p < 0.001), cobalamine (OR = 0.01; 95 per cent CI = 0.00, 0.01, p < 0.001) , selenium (OR = 0.79 ; 95 per cent CI =1.36, 3.32, p < 0.001), iron (OR =0.68; 95 per cent CI = 0.24, 0.94, p < 0.001) and iodine (OR = 0.36; 95 per cent CI =1.10, 1.38, p < 0.001) had a protective effect on the incidence of PPD. Furthermore, higher intake of vitamin A and beta-cryptoxanthin can increase the incidence of PPD (OR =114.29; 95 per cent CI =17.85, 118.12, p < 0.001) and (OR = 4.85; 95 per cent CI = 1.49, 15.69, p = 0.015), respectively.

Originality/value

PPD may have destructive effects on the relationship between mother and infant. Results of previous studies demonstrated nutrients are required for the synthesis of neurotransmitters and have biochemical role in the nervous system.

Abstract

Purpose

This study aims to investigate whether human capital readiness affects business performance, and if so, whether the effect is mediated by global market orientation.

Design/methodology/approach

This is a quantitative study employing partial least square structural equation modeling (PLS-SEM) to test the hypotheses. Using a survey method, the data were collected using both online and offline questionnaires. As many as 433 owners/managers of micro-, small- and-medium-sized enterprises (MSMEs) in the East Java Province of Indonesia participated in this study. A mediating research framework was developed to investigate the mediating role of global marketing orientation on the human capital readiness–business performance relationship.

Findings

The results show that human capital readiness has a direct and positive effect on business performance. Further analysis reveals that global market orientation partially mediates the effect of human capital readiness on business performance.

Research limitations/implications

First, this study focuses on the MSMEs in the East Java Province of Indonesia. Caution needs to be taken if the results are generalized to other regions. Second, it employed a survey method that is commonly criticized as having the potential to be biased.

Practical implications

The findings provide a more comprehensive understanding of owners/managers of human capital readiness and how it should be improved to better execute global market orientation strategies to achieve the desired business performance.

Social implications

Because MSMEs play a crucial role in society, this study provides a general model to improve the welfare of society by enhancing the MSMEs' business performance. By understanding its antecedents, namely, human capital readiness and the global market orientation, improvements can be made.

Originality/value

Human capital readiness has been rarely examined in previous studies. This is the only study applying the constructs of human capital readiness, global market orientation and business performance to the Indonesian MSME research setting.

Abstract

Purpose

This study aims to examine the methods of converting the threats caused by sanctions on Iran’s petrochemical industry to economic opportunities and investigating the growth rate of Iran’s petrochemical industry during sanctions.

Design/methodology/approach

The present research was descriptive-exploratory and the research method was based on a mixed research strategy. In the qualitative part, two methods of content analysis and semistructured interview were used and in the quantitative part, the survey method was used. The participants of the qualitative part were the content of all related published researches that have been published in the past 20 years and to conduct a semistructured interview with experts that were selected by nonprobability sampling method. In the quantitative part, the statistical population, there were including managers, supervisors and experts active in the Iran’s petrochemical industry (especially in Asaluyeh area of Iran), the sampling method was nonprobability of the type available.

Findings

The findings of the research showed that the potential risks resulting from the sanctions on Iran’s petrochemical industry from the review of the selected researches include 5 main risks (marketing, financial, supply and procurement, technological and production) and 26 related subrisks. Also, the ranking of the mentioned risks showed that among the main risks, the highest rank is related to the financial risk and among the subrisks, the increase in transaction costs and disruption in the implementation of contractual obligations have the highest rank.

Research limitations/implications

The investigation of the growth rate of Iran’s petrochemical industry during the sanctions in terms of performance (production, export and foreign exchange) showed that the amount of production has gone through a growing trend during the period under review (it has grown by more than 68%). Also, the amount of exports in the investigated time period has been growing (it has grown by more than 70%) and finally, the amount of foreign exchange in this time period has experienced growth (more than 58% growth).

Originality/value

Introducing and examining methods of turning threats into economic opportunities in Iran’s petrochemical industry under the shadow of sanctions, which can be used in other active industries under sanctions in the energy field.

Abstract

Purpose

The global imperative for sustainable infrastructure management has intensified the focus on facility retrofitting as a key strategy for reducing environmental impact and enhancing operational efficiency. However, the complex interplay of factors influencing stakeholders’ willingness to pay (WTP) for such interventions remains inadequately understood, impeding effective policy formulation and resource allocation. This study aims to examine the motivational factors influencing the adoption of green retrofits in Lagos, Nigeria.

Design/methodology/approach

This study used a stated preference discrete choice experiment conducted with 425 decision-makers of corporate facilities in Lagos, Nigeria. A multinomial logit model was used to compare retrofitting choice sets and a status quo option.

Findings

The study revealed that education level, reputation concerns, income, incentives and corporate social responsibility awareness significantly predicted WTP for basic heating ventilation air-conditioning, and lighting upgrades. Regulatory compliance, awareness, education, income and reputation emerged as key drivers for more comprehensive retrofits incorporating renewables.

Practical implications

The research findings, by revealing which motivators resonate strongest, offer an evidence-based roadmap that directs practitioners to look beyond price incentives and emphasize complementary non-price interventions integrated with policy. The study’s emphasis on the significance of noneconomic WTP drivers equips program administrators with actionable strategies to optimize the uptake of retrofits based on individuals’ motivational structures.

Originality/value

This is one of the very few studies that have investigated the motivational factors influencing the adoption of green facility retrofitting in emerging markets, focusing on Lagos, Nigeria.

Abstract

Purpose

The cost-optimal analysis is not able to address the multi-dimensionality of the decision according to the new European objectives and International sustainable development goals in the field of the nearly-zero energy building (NZEB) design. The purpose of this paper is to study the role of multi-criteria decision analysis (MCDA) for guiding energy investment decisions.

Design/methodology/approach

The paper explores the Preference ranking organization method for enrichment of evaluations II (PROMETHEE II) application to support the project of transforming a rural building into a NZEB. The evaluation provides an estimate of the effects of alternative energy efficiency measures, involving energy consumption, life cycle costs, carbon emissions, property value and indoor comfort criteria. The study performs a multi-actors analysis in order to understand how different consumers' point of views can influence the final choice of the best investment. Furthermore, a multi-site analysis explores the spatial variation of NZEB building appreciation in the real estate market.

Findings

The PROMETHEE II-based model ranks 16 alternative solutions for the NZEB according to energy, economic and extra-economic criteria. The multi-actors analysis highlights the configuration of the NZEB building that best meets the needs of different end-users, respecting the European directives and national standards. The multi-site analysis concludes that location does not change users' appreciation and not influence the output for the best solution.

Originality/value

The MCDA occurs as a support tool that helps to optimize the preliminary design phase of NZEB through the exploration of the optimal solution considering crucial criteria in the energy and environmental and real estate market rules.
