Abstract

Purpose

The paper aims to study the effects of humidity on the electrical properties of copper phthalocyanine (CuPc) thin films deposited at different gravity conditions.

Design/methodology/approach

Surface-type samples were fabricated on glass substrates with preliminary-deposited copper electrodes. The CuPc solution was prepared in benzene. The thin films of CuPc were deposited on these substrates at diverse gravity conditions by drop-casting and centrifugation at 1 × g and 70 × g, respectively. Impedance and capacitance of the fabricated devices were measured against the different relative humidity ranging from 32 to 98 per cent.

Findings

The impedance and the capacitance of the CuPc film were found to be dependent on the ambient humidity levels (32-98 per cent) and the gravity conditions (1 × g and 70 × g) opted during the fabrication process.

Research limitations/implications

The centrifugation technique can potentially be used in the instrumentation industry for the fabrication of humidity sensors.

Practical implications

The results of the investigations can potentially be used in the instrumentation and optoelectronics industry for the fabrication of humidity sensors.

Originality/value

CuPc films were deposited from a solution in benzene using drop-casting and centrifugation. The electrical properties of the films were found to be dependent on film fabrication conditions and ambient humidity levels. Growth-dependent electrical properties of the CuPc films can be explained by considering their structure.

Abstract

Purpose

The green aspects in current management practices are strongly emphasized for sustainable and environment friendly business operations. Thus, building on ability-motivation-opportunity (AMO) theory, this study aims to test the mediating role of green absorptive capacity in the relationship between green human resources management (GHRM) practices (i.e., green training and development, and green performance management) and organizational citizenship behavior towards environment (OCBE).

Design/methodology/approach

Using a paper-pencil survey, the authors collected data from 170 middle-tier officers working in cement industry of Pakistan. Structural equation modeling technique was applied for data analysis through Smart-PLS.

Findings

Results indicated that GHRM practices significantly influence OCBE and green absorptive capacity partially mediates the relationship between GHRM practices and OCBE.

Originality/value

This study offers new theoretical and practical insights by empirically investigating the mediating role of green absorptive capacity between GHRM practices and OCBE through the lens of AMO theory. Furthermore, this study contributed in disclosing the predictors of OCBE through intervening mechanism in manufacturing sector of developing country for sustainable outcomes.

Abstract

Purpose

Organizations today strive to differentiate themselves from others with the help of various tools. Aaker’s brand personality model is one of them. It comprises five components namely, sincerity, excitement, sophistication, competence and ruggedness. This model has been tested and supported by various scholars in the past. Similarly, it also attracted a lot of criticism especially in terms of generalizability across countries and cultures. The purpose of this paper is twofold: first, to study Aaker’s model from an Islamic perspective; second, considering the dearth of brand personality knowledge in the services sector, to develop Islamic Banks’ Brand Personality (IBBP) model.

Design/methodology/approach

To propose IBBP model, traits in Aaker’s model have been investigated in the light of selected Quranic verses and sayings of Prophet Muhammad (ahadith). Later on, content validation was conducted as a pilot study with experts from the relevant fields.

Findings

Findings exhibit that Quran and hadith clearly elaborate and support majority dimensions of the existing model. Importantly, three new dimensions, namely, trustworthiness, justice and Shariah compliance, were added to develop a comprehensive IBBP model. Once the dimensions of IBBP model were finalized, the underlying items were content validated from 12 experts. Most of the items were approved; some were recommended for amendments and a few items were eliminated.

Practical implications

This research contributes to the branding as well as bank marketing literature as it is the first Islamic banks’ brand personality framework. With the help of IBBP model, Islamic banks can create a better brand image, use advertising strategies effectively and ultimately retain existing and attract more potential customers.

Social implications

This research elaborates the personality traits of Muslim consumer market. Following IBBP model, financial needs of Muslim consumer market can be catered effectively.

Originality/value

The IBBP model being first of its kind is significant for Islamic banking industry as it reflects dimensions that are supported by the Quran and hadith, and therefore suits Muslim customer market.

This paper aims to present the studies which were carried out to determine building typology in Northern Pakistan, which is a seismically active region.

Abstract

Purpose

This paper aims to present the studies which were carried out to determine building typology in Northern Pakistan, which is a seismically active region.

Design/methodology/approach

A total of 41 towns and cities were surveyed to collect the data of building types. Help was also taken from global positioning system and satellite imagery.

Findings

In total, 14 different types of buildings were identified in the region based on the structural system and combination of wall and roof materials; each of them was assigned an appropriate designation. The walls in these buildings were made of block, stone or brick, whereas the roof consisted of corrugated galvanised iron sheet, thatched roof, precast concrete planks or reinforced concrete (RC). Only 6 per cent buildings were found to be engineered RC buildings; this indicates a significance proportion of non-engineered building stock in Northern Pakistan.

Research limitations/implications

The surveys were conducted in some of the selected areas. Other areas are beyond the scope of this work.

Practical implications

The presence of a huge deficient building stock in Pakistan indicates a major seismic risk. The seismic losses are largely dependent on the earthquake resistance of existing buildings and building stock. An inventory of existing buildings and their types can help in assessing seismic vulnerability of the built environment, which may lead to the development of policies for seismic risk reduction.

Originality/value

Presently, housing encyclopaedia does not exist in Pakistan. As a result, housing typology in the country is not known. The presented study addresses this gap in part. Housing typology surveys were conducted to study the typical construction practices in the selected areas and to determine the proportions of different building types in the overall building stock.

Abstract

Purpose

The purpose of this paper is to explore how different forms of integration interact with environmental dynamism to influence the outcomes of a buyer–supplier relationship (BSR). Specifically, the authors assess the impact of communication, operational process integration (OPI) and joint knowledge exploration (JKE) on the economic value and competitive differentiation generated by the BSR. Furthermore, the authors assess the moderating role of environmental dynamism in changing the performance implications of these different forms of integration.

Design/methodology/approach

The authors empirically test the theoretical model using survey data collected from North America. The authors apply techniques such as confirmatory factor analysis, regression and a variety of robustness checks to ensure the validity of the findings.

Findings

The results indicate that OPI and JKE are useful in generating higher value from key supply chain relationships. However, communication does not directly influence performance outcomes, rather it assists in the implementation of other forms of integration. In stable environments, better returns can be obtained from focusing on OPI, while in dynamic environments JKE becomes far more important.

Originality/value

This study shows that different aspects of integration have very different performance implications and that selective integration can outperform broad-based integration in some conditions. More importantly, the performance implications depend on environmental dynamism in unique ways, where greater integration is not always the best response to dynamic business conditions. The results allow managers to make better decisions regarding what forms of integration to establish in key supply chain relationships.

In this study, the behavior of a multi-story flat plate structure during fire exposure is investigated using numerical simulations conducted with using ABAQUS software.

Abstract

Purpose

In this study, the behavior of a multi-story flat plate structure during fire exposure is investigated using numerical simulations conducted with using ABAQUS software.

Design/methodology/approach

A three-dimensional finite element model is then carried out on the RC flat slab structure exposed to standard ISO-834 fire at different location arrangements. The model examines mid-span deflection, shear demand on the columns, bending moment and the membrane action of the floor slab.

Findings

The latter plays a main role to increase the capability and ductility of the slab at longer fire exposure to compensate the reduction in the flexural capacity. Also, shear demand in columns becomes bigger in cases of more than one surrounding slab exposed to fire at the same time.

Originality/value

This work focuses on the influence of the horizontal force on columns due to thermal expansion of slab which should be taken into account in the design of multistory multi-bay building considering it the same as the resulted horizontal force from the wind and seismic effect, the traveling fire and the restraint effect.

Abstract

Purpose

Islamic banking industry with all of its exponential growth and global recognition has been under criticism for the past two decades. However, the problem signifies further when such criticism is made from within the organization and is well supported by outside (the customers). The purpose of this study is to provide a coherent exploration to investigate the factors that polarize its employees and customers across many parts of the world.

Design/methodology/approach

To investigate the phenomenon, a total of 30 responses were taken through interviews 15 each from customers and employees. Afterwards, the data was analysed and summarized into two categories. In doing so, the top five Malaysia’s Islamic banks were shortlisted to collect data from employees and customers.

Findings

A detailed thematic analysis resulted in six themes (Contradiction between theory and practice, Islamic banking knowledge and awareness, inadequate Shariah training, employees’ background, Shariah compliance, Islamic banking benefits) for employees and five (Islamic banking benefits, applying Shariah in Islamic banking, knowledge of Islamic banking, Islamic banking promotion, Islamic banking employees’ behaviour) for customers, respectively.

Research limitations/implications

The results have stronger implications for both practice and theory as organizations can assess stakeholders and their perceptions about Islamic banking. Another implication is the comparative examination of employees and customers which can potentially affect decision and policy making in Islamic banks. Islamic banks can also address employment-related issues related to employees’ behaviour vis-à-vis marketing-related problems faced by its customers that will ultimately improve its global market share and strategic positioning.

Originality/value

The study is based on the importance of Islamic banking in Malaysia and explores the factors that potentially create a positive or negative insight into Islamic banking – both in employees and customers.

Abstract

Purpose

Does entrepreneurship education (EE) really enhance participants’ self-efficacy and influence their attitudes towards starting new business? How does this attitudinal influence relate to participants’ entrepreneurial intention (EI)? Researchers and entrepreneurs alike have been probing into these questions with a view to capacitate the need of EE. This study aims to understand and operationalize a framework for entrepreneurship development by measuring participants’ intention towards entrepreneurship.

Design/methodology/approach

The study proposed a sequential mediation framework to examine the impact of EE on EI mediated by self-efficacy and attitude towards starting new business. Testing the hypotheses on data collected from 380 individuals, the study provided differentiated support for the theoretical propositions.

Findings

The findings of the study reflect that EE, self-efficacy and attitude towards starting new business contribute in establishing EI of audience. It was concluded that a sequential mediation exists between EE and EI by channelizing through entrepreneurs’ self-efficacy level that transforms an attitude towards starting a new business venture.

Research limitations/implications

The study has both theoretical and practical implications that will enable academicians, managers and practitioners to facilitate entrepreneurship by enhancing their knowledge database, skillset and developing a positive and constructive attitude among potential entrepreneurs.

Originality/value

The study inculcates a cultural lens and differentiates Pakistani context with other developing countries in Asia.

Abstract

Purpose

The aim of this study was to identify and evaluate interventions shown to improve nurse resilience in the acute care settings.

Design/methodology/approach

The study was a systematically conducted scoping review of the literature. Databases including MEDLINE/PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Emerald insight and Google Scholar were searched and this complemented by reviews of the reference lists.

Findings

In total, 13 papers were included in the review but there was limited evidence of the effectiveness of individual programs. The authors found that resilience training programs for individuals reviewed provided some evidence for the effectiveness of the training. However, the context of job design, work risks and leadership require attention.

Originality/value

Resilience is an important requirement for nursing staff that helps to mitigate the stress of the working environment, particularly in the acute care setting. However, the managerial strategies required to build resilience are not well known or applied. The findings of this research may help to design cohesive and comprehensive management programs to promote and preserve nursing resilience in acute care settings. Any such program needs to reflect the four key themes that appear to underpin resilience: relationships, motivation, emotions and well-being.

Abstract

Purpose

To explore the perceptions of surgical team members in a tertiary hospital in Jordan toward the factors influencing patient safety culture (PSC).

Design/methodology/approach

This was a qualitative descriptive study intended to characterize the factors that influence PSC. Interviews were conducted with health-care providers in the operation room (OR) in a tertiary Jordanian hospital. Participants included surgeons, anesthetists, nurses and senior surgical residents who had worked for three years minimum in the OR. Thematic analysis was used to analyze the data.

Findings

A total of 33 interviews were conducted. Thematic analysis of the content yielded four major themes: (1) operational factors, (2) organizational factors, (3) health-care professionals factors and (4) patient factors. The respondents emphasized the role of the physical layout of the OR, implementing new techniques and new equipment, and management support to establish a safety culture in the operating room setting.

Originality/value

The present research study will have implications for hospitals and health-care providers in Jordan for developing organizational strategies to eliminate or decrease the occurrence of adverse events and improve patient safety in the OR.
