Literature on organizational commitment of employees has long established that quality of work life (QWL) is a significant determinant. However, the strength of the relationship between organizational commitment and QWL is more complicated given the diversity of employees and the broad scope of organizational commitment as a construct. The researchers break down organizational commitment into three distinct measures as extant literature suggests and then explore the role played by gender in a culturally rich context as in Egypt.

This paper is based on a sample of 117 respondents from small and medium enterprises (SMEs). Items used in the survey were extracted from previous research studies. The survey consisted of 39 questions to measure the three research variables. QWL was measured using Zin’s (2004) developed questionnaire. The items covered seven dimensions: growth and development, participation, physical environment, supervision, pay and benefits, social relevance and workplace integration. The reported Cronbach’s alpha for the scale was 0.93. Items were measured on a five-point Likert scale.

The researchers empirically found that gender plays only a minor and moderating role in the relationship between QWL and affective commitment. The researchers conclude the study with implications for policy, practice and future research.

This study had several limitations. First, the sample size was relatively small. Second, the sample composition (singular focus on SMEs in Egypt) was not diverse enough. Third, the tools used in collecting the data were not adjusted to the national cultural context. Fourth, the study lacks an experimental design which is a limitation (Shadish et al., 2002). These limitations, taken together, limit the generalizability of the results and conclusions from the study. Thus, the results are suggestive rather than definitive. Additionally, only the association between variables was investigated, and the researcher did not clearly explore the cause–effect relationships. Whether QWL is the antecedent or the consequence is another research question yet to be explored.

It is recommended for future researchers to enlarge and diversify the sample. Additional investigations of the role of gender as a mediator or moderator need to be explored. Researchers should also study the roles of other demographic variables to highlight behavioural and attitudinal variables that significantly affect QWL.

While the primary relationship between “perceived quality of work life” and “organizational commitment” is well established in existing literature across many organizational contexts, there is a paucity of research on the moderating and/or mediating effects of third attitudinal variables on this primary relationship. Hence, the main focus of this study was to empirically test the moderating and/or mediating effects of gender on the relationship between “perceived quality of work life” and “organizational commitment.” The researchers examine organizational commitment more granularly in terms of its components, namely, affective, continuance and normative commitments.

The purpose of this study is to inspect the corrosion inhibition of API N80 steel pipelines in uninhibited solution and inhibited with a synthesized surfactant compound [N-(3-(dimethyl octyl ammonio) propyl) palmitamide bromide] (DMDPP), which is prepared through a simple and applicable method.

Weight loss was inspected at five different temperatures of 25°C, 30°C, 40°C, 50°C and 60°C Potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and electrochemical frequency modulation were used at room temperature. Density functional theory was used to study the relation between the molecular structure and inhibition theoretically.

Adsorption of the prepared DMDPP fits the Langmuir isotherm model. The inhibition efficiency of the prepared DMDPP amphipathic inhibitor is directly proportional to temperature increase. Polarization results reveal that the investigated DMDPP amphipathic compound behaves as a mixed-type inhibitor. EIS spectra produced one individual capacitive loop.

The originality is the preparation of cationic surfactants through a simple method, which can be used as corrosion inhibitors in oil production. The synthesized inhibitors were prepared from low-price materials. The work studied the behavior of the synthesized surfactants in inhibiting the corrosion of the steel in an acidic medium. Electrochemical and theoretical studies were presented, besides gravimetric and surface examination.

The purpose of this article is to revisit the concepts of city singularity and identity, as well as the concept’s related topics (i.e. place identity, place attachment and place dependence). The aim is to investigate the impact of development projects on people's preferences for old and contemporary features in modern cities. The evidence for this can be seen mainly at historical sites such as Heliopolis in Cairo, Egypt.

The authors investigated how development projects affect place identity and city singularity through a three-step process. As a first step, an online questionnaire was administered to experts to assess the characteristics that shape the identity of local districts. In the second and third steps, interviews were conducted, followed by online surveys directed at Heliopolis residents and non-residents. The weight of people’s preferences was determined using multi-criteria decision-making (MCDM).

The results highlighted people's preferences to consider when developing projects at historical sites. Based on these preferences, the authors’ concluded remarks provide insight into some considerations for developing projects in historic places.

The added value here is surveying people’s preferences about development projects in historical places. The physical and social components interplay contributes to city identity and singularity. Based on these preferences, this investigation offers valuable insights into enhancing historical site development.
