Abstract

Purpose

The purpose of this paper is to study the effect of the nano tube fillers on the corrosion protection properties of the self-curing epoxy (SEP) coatings.

Design/methodology/approach

The self-curing epoxy (SEP) resin was synthesized via a reaction between diisopropoxy-bis ethylacetoacetato titanate and the epoxy resin. Halloysite nanotubes (HNTs) was surface modified by grafting (3-glycidoxypropyl) trimethoxysilane to obtain modified HNTs (mHNTs). The HNTs and mHNTs are used as nano tube fillers for the SEP coating. The thermal stability of the coatings was assessed via thermo-gravimetric analysis. The field-emission scanning electron microscopy (SEM) was conducted to analyze the surfaces and cross sections of the coatings. The anticorrosive efficiencies of the coatings were investigated by electrochemical measurements and a neutral salt spray test.

Findings

The results demonstrated that the additions of HNTs and mHNTs have little effect on the thermal degradation temperature of the SEP coating. However, the addition of the nanotubes reduced the corrosion resistance of the SEP coating.

Originality/value

The SEP coating itself showed excellent corrosion resistance without any reinforcement particles and is hence promising for application in the heavy-duty anticorrosion field of heat exchangers.

Abstract

Purpose

The purpose of this paper is to examine the impact of corporate governance, investor sentiment and financial liberalization on downside systematic risk and the interplay of socio-political turbulence on this relationship through static and dynamic panel estimation models.

Design/methodology/approach

The evidence is based on a sample of 230 publicly listed non-financial firms from Pakistan Stock Exchange (PSX) over the period 2008–2018. Furthermore, this study analyzes the data through Blundell and Bond (1998) technique in the full sample as well sub-samples (big and small firms).

Findings

The authors document that corporate governance mechanism reduces the downside risk, whereas investor sentiment and financial liberalization increase the investors’ exposure toward downside risk. Particularly, the results provide some new insights that the socio-political turbulence as a moderator weakens the impact of corporate governance and strengthens the effect of investor sentiment and financial liberalization on downside risk. Consistent with prior studies, the analysis of sub-samples reveals some statistical variations in large and small-size sampled firms. Theoretically, the findings mainly support agency theory, noise trader theory and the Keynesians hypothesis.

Originality/value

Stock market volatility has become a prime area of concern for investors, policymakers and regulators in emerging economies. Primarily, the existence of market volatility is attributed to weak governance, irrational behavior of market participants, the liberation of financial policies and sociopolitical turbulence. Therefore, the present study provides simultaneous empirical evidence to determine whether corporate governance, investor sentiment and financial liberalization hinder or spur downside risk in an emerging economy. Furthermore, the work relates to a small number of studies that examine the role of socio-political turbulence as a moderator on the relationship of corporate governance, investor sentiment and financial liberalization with downside systematic risk.

Abstract

Purpose

The paper aims to test the effect of liquidity creation on profitability and stability with the moderating role of political instability and its level of implication on the overall banking sector of Pakistan.

Design/methodology/approach

This study uses the panel data estimation technique, including fixed- and random-effect model, by taking sample data of 28 banks of Pakistan that are providing their services from 2006 to 2019. Moreover, this study uses the Genreralized Method of Moments (GMM) estimation technique to check the robustness of the results.

Findings

The empirical outcomes of this study found a negative relationship of liquidity creation with profitability meanwhile positive relation with banking stability. However, this study shows a negative relation of political instability with liquidity creation, profitability and stability of overall banks of Pakistan.

Practical implications

The findings of this paper recommended the vital role of liquidity creation in the profitability and stability of banks, especially in the decision-making process of the investors and bank managers, and how it is affected strongly in the presence of an unstable political situation. These findings may be helpful for policymakers to devise appropriate policies to maintain a fair field between state authority and financial institutions and also assist in formulating strategies to strengthen the banking sector of Pakistan to avoid financial turmoil in the future.

Originality/value

As per the knowledge of the authors, this study is the first contribution to examine the moderating effect of political instability on liquidity creation, profitability and stability of the overall banking sector of Pakistan.

Abstract

Purpose

With a foundation in the conservation of resource theory, this paper aims to examine the validity of a conceptual model that explains the mechanism connecting perceived threat of terrorism to production deviance. The link between perceived threat of terrorism and production deviance was examined via emotional exhaustion. Notably, the study evaluated whether the relationship between perceived threat of terrorism and production deviance is mediated by emotional exhaustion and moderated by levels of emotional intelligence.

Design/methodology/approach

The study is cross-sectional in nature and data were collected from 432 pharmaceutical sales representatives who operate outdoors in the high-risk region. Two-step approach consisting confirmatory factor analysis and structural equation modeling was used for analysis. To examine conditional direct and indirect effects, the authors used model 8 in PROCESS.

Findings

Results were consistent with prediction made from the conceptual model in that emotional exhaustion partially mediated the relationship between perceived threat of terrorism and production deviance. This was particularly the case when emotional intelligence was low, but not when high. Likewise, perceived threat of terrorism exerted a direct effect on production deviance when emotional intelligence was low, but not when high.

Originality/value

The study is the first to examine the relationship between perceived threat of terrorism and production deviance. Moreover, no study to date has examined the mediating role of emotional exhaustion between perceived threat of terrorism and production deviance. Finally, up till now, it is unknown that emotional intelligence moderates the relationship of perceived threat of terrorism with emotional exhaustion and production deviance.
