Abstract

Purpose

This paper emphasizes the theoretical relevance that workplace spirituality may add to the person–organization (P-O) fit theory through the examination of a framework that comprises how workplace and self-spirituality fit enhances the perceived P-O spirituality fit. A related aim is to test how the perceived P-O spirituality fit enhances both employees' ethical and spiritual leadership behavior.

Design/methodology/approach

Data were collected using a quantitative study of 132 employees across various organizations in Jordan. Data were firstly checked by the use of exploratory factor analysis (EFA) and reliability tests. Hypotheses have been tested by the use of hierarchical multiple regression analysis.

Findings

In line with the hypotheses, the study's results exhibited that workplace and self-spirituality fit positively enhances the perceived P-O spirituality fit. The results also show that the perceived P-O spirituality fit enhances both employees' ethical and spiritual leadership behaviors.

Practical implications

The present study warrants several practices for human resource management (HRM), policy and development. It suggests that HRM practices should encourage a more “spiritual– and ethical-friendly” environment by ensuring that staffing and other HRM responsibilities are clearly committed to ethics and supportive of spirituality. Specifically, within performance appraisal policies, HR managers may include specific policies and ethical action targets to promote more ethical behaviors. There may be regular monitoring to track the trajectory of the HRM practices in this regard.

Originality/value

The contribution of this paper extends beyond the vast literature on P-O fit with the generation of a new concept (i.e. P-O spirituality fit) to the literature in a Muslim-majority country. This offers reinvigorated awareness of the topic under study and suggests specific future research directions.

Abstract

Purpose

The purpose of this paper is to investigate three Arylfuranylnicotinamidine derivatives against corrosion of carbon steel (C-steel) in 1.0 M HCl by chemical and electrochemical means. The inhibition efficiency (%IE) increases with increasing the dose of inhibitors. The tested compounds exhibited improved performance at elevated temperature, with %IE reaching 93 percent at 21 µM. Tafel polarization method revealed that the tested compounds act as mixed-type inhibitors. The inhibition action was rationalized due to chemical adsorption of inhibition molecules on C-steel surface following Temkin’s isotherm. Surface examination was carried out by AFM and FTIR techniques. Further, theoretical chemical approaches were used to corroborate the experimental findings.

Design/methodology/approach

Experimental and computational methods were applied to investigate the efficiency of these new compounds. These studies are complemented with spectral studies and surface morphological scan by AFM. The theoretical results indicate good correlation with experimental findings.

Findings

The tested derivatives are promising corrosion inhibitors for C-steel in the acid environment. The molecular scaffold of this class of compounds can be used to design new highly efficient inhibitors by screening its activity by modeling studies.

Originality/value

The studied compounds are safe inhibitors and greatly adsorbed on Fe surface. The action of compounds is enhanced with temperature, which means these compounds can be used in higher temperature systems. The new compounds are effective at very low concentration.

Abstract

Purpose

This paper aims to investigate the influence of temperature (25-65°C) on the adsorption and the inhibition efficiency of gum arabic (GA) for the corrosion of API 5L X42 pipeline steel in 1M HCl.

Design/methodology/approach

Inhibition behaviour on steel in HCl has been studied in relation to the concentration of the inhibitor and the temperature using potentiodynamic polarization curves and electrochemical impedance spectroscopy. Thermodynamic parameters of adsorption were calculated from the viewpoint of adsorption theory.

Findings

The results show that at a temperature range from 25 to 65°C, GA was a good inhibitor for API 5L X42 pipeline steel, and its inhibition efficiency was significantly stable. The maximum inhibition efficiency (93 per cent) is obtained at 4 g L−1. In absence and presence of GA, there is almost no change in the corrosion mechanism regardless of the temperature. The adsorption of GA on steel surface is an exothermic process. The adsorption of GA involves physical adsorption.

Practical implications

The use of GA as an eco-friendly corrosion inhibitor is practical for carbon steel in HCl.

Originality/value

The stability of inhibition efficiency of GA at a temperature range from 25 to 65°C could find possible applications in acid pickling, industrial acid cleaning and acid descaling.

Abstract

Purpose

The purpose of this paper is to investigate how different measures of working conditions affect the health at work of female and male workers of 15 European countries. Particular attention is paid to the gender dimension of this relationship.

Design/methodology/approach

Using the European Working Conditions Survey from 2005 the author describes differences in health at work by gender accounting for both psychosocial and physical hazards at work. A Probit OLS estimator is used to obtain the relevant estimates and endogeneity problems have been properly addressed.

Findings

Results show that controlling for a broad selection of personal and work attributes, working conditions are associated with more work related health problems – both physical and mental. Importantly, some evidence is found in support of a different pattern by gender. With respect to mental health at work, males suffer more from high work demands/low job autonomy compared to females. Task segregation may play a role in explaining these differences. A less clear pattern across gender is found with respect to physical health problems at work. When the endogeneity of working conditions is taken into account, results are confirmed and show that the effect of working conditions on health at work is under‐estimated when endogeneity is not accounted for.

Originality/value

The paper's findings contribute to shed more light on the controversial analysis between working conditions and health according to gender.

Abstract

Purpose

As the number of social media users continues to rise globally, a heated debate emerges on whether social media use improves or harms mental health, as well as the bidirectional relation between social media use and mental health. Motivated by this, the authors’ study adopts the stressor–strain–outcome model and social compensation hypothesis to disentangle the effect mechanism between social media use and psychological well-being. The purpose of this paper is to address this issue.

Design/methodology/approach

To empirically validate the proposed research model, a large-scale two-year longitudinal questionnaire survey on social media use was administered to a valid sample of 6,093 respondents recruited from a university in China. Structural equation modeling was employed for data analysis.

Findings

A longitudinal analysis reveals that social media use positively (negatively) impacts psychological well-being through the mediator of nomophobia (perceived social support) in a short period. However, social media use triggers more psychological unease, as well as more life satisfaction from a longitudinal perspective.

Originality/value

This study addresses the bidirectional relation between social media use and psychological unease. The current study also draws both theoretical and practical implications by unmasking the bright–dark duality of social media use on psychological well-being.

Abstract

Purpose

The purpose of this study was to examine the copper protection against corrosion using 3-thiophenemalonic acid (3TMA).

Design/methodology/approach

The heterocyclic organic molecule was tested experimentally as a corrosion inhibitor of copper in two different concentrations (0.01 M and 0.001 M) in 0.5 M solutions of sodium chloride and sulfuric acid by AC electrochemical and DC techniques.

Findings

Results showed that the organic compound was adsorbed chemically on the copper surface, and the inhibitions mechanism was both anodic and cathodic. The corrosion mechanism was under mixed control: charge transfer from metal to the environment through the double electrochemical layer, and diffusion processes.

Practical implications

This inhibitor could have application in water cooling systems.

Originality/value

The results of this paper showed that 3TMA could be used for reducing corrosion rates of copper in solutions of sodium chloride and sulfuric acid.

Abstract

Purpose

Over the past two decades, the application of most-favoured-nation (MFN) clauses in international investment agreements (IIAs) to dispute settlement matters has generated controversy. The purpose of this paper is to help resolve some of the controversies by examining the rule of law issues that may arise from such application of MFN.

Design/methodology/approach

The study describes controversies regarding the application of MFN to dispute settlement as per the extant literature on the subject. It explores the elements of rule of law in investor-state arbitration. The paper then analyses the implications of applying MFN to dispute settlement matters for the elements of rule of law. Based on such analysis, the study argues that the application of MFN to dispute settlement matters undermines certain elements of rule of law.

Findings

The paper has outlined the relevant elements of rule of law in investor-state arbitration as access to dispute settlement; judicial (or tribunal) independence, fairness and impartiality; consistency and predictability of law and decisions; transparency; accountability and subjection of dispute forums and systems to law. It found that the application of MFN undermines various components of rule of law, in particular of consistency and predictability and the requirement of tribunals to adjudicate within the limits of the law.

Originality/value

The findings of this study will help future investor-state arbitral tribunals to decide on the application of MFN to dispute settlement matters.

Abstract

Among recent criticisms levelled against traditional administrative theory those raised by adherents to the Critical Theory perspective have gained considerable influence. This paper examines their claim that Habermasian Critical Theory in particular is in a better position to solve the theoretical and practical problems of educational administration. The focal points of discussion are Habermas's fundamental categories of “interests” and the “ideal speech situation” since their theoretical coherence is a minimum requirement for the theory's validity and practical applicability. It is concluded that Critical Theory, while being the most ambitious attempt to date to provide a new, post‐positivist framework for social and administrative studies, has insufficient epistemological resources to justify its claims. As a result, the theory is driven to rational a prioris which deprive it of empirical content and relevance. Since Critical Theory claims to have reunited theory with practice, lack of empirical content would seem to disqualify the claim and render questionable the theory's value for educational administration.
