Abstract

Purpose

The main purpose of this study is to examine the damage behavior of flexural members under different loading conditions. The finite element model is proposed for the prediction of modal parameters, damage assessment and damage detection of flexural members. Moreover, the analysis of flexural members has been done for the sensor arrangement to accurately predict the damage parameters without the laborious work of experimentation in the laboratory.

Design/methodology/approach

Beam-like structures are structures that are subjected to flexural loadings that are involved in almost every type of civil engineering construction like buildings, bridges, etc. Experimental Modal Analysis (EMA) is a popular technique to detect damages in structures without requiring tough and complex methods. Experimental work conducted in this study concludes that a structure experiences high changes in modal properties once when cracking occurs and then at the stage where cracks start at the critical neutral axis. Moreover, among the various modal parameters of the flexural members, natural frequency and mode shapes are the viable parameters for the damage detection.

Findings

For torsional mode, drop in natural frequency is high for higher damages as compared to low levels. This is because of the opening and closing of cracks in modal testing. When damage occurs in the structure, there is a reduction in the magnitude of the FRF plot. The measure of this drop can also lead to damage assessment in addition to damage detection. The natural frequency of the system is the most reliable modal parameter in detecting damages. However, for damage localization, the next step after damage assessment, mode shapes can be more helpful as compared to all other parameters.

Originality/value

Effect on Dynamic Properties of Flexural Members during the Progressive Deterioration of Reinforced Concrete Structures is studied.

Abstract

Purpose

Building on high-performance organizations (HPO) framework, the purpose of this paper is to hypothesize the direct impact of five factors of HPO framework on public organizations’ performance in Pakistan. This is first research to employ the partial least squares (PLS) method to provide empirical evidence of the predictive power of the framework in public organizations.

Design/methodology/approach

This is a cross-sectional study conducted in non-contrived settings thereby keeping researcher interference to a minimum. Data collection was carried out by distributing online questionnaires to 513 employees from three different service-based public organizations in Pakistan. PLS is used to examine the statistical and substantive significance of five factors by employing SmartPLS 3.2.6.

Findings

This study concludes that the HPO framework has predictive relevance for public organizations’ performance surveyed in this study. Furthermore, three out of the five factors of HPO framework, namely, management quality, workforce quality and long-term orientation have positive relationships, while openness and action orientation (OAO), and continuous improvement process and renewal have a negative relationship with the performance of public sector organizations (PSOs) surveyed in Pakistan.

Research limitations/implications

The study’s small sample size limits this research, and only quantitative methodology is applied. A significant limitation of this research is that this study relied on a subset of respondents of surveyed organizations and may not representative of the population. Therefore, result should be carefully interpreted as some degree of biasness may be present. Furthermore, findings of the study cannot be generalized to all PSOs of Pakistan.

Practical implications

The implication for public managers is that the HPO framework has predictive relevance and substantive significance. However, the ideal value of HPO framework will occur when leadership considers HPO factors and struggles persistently to improve performance. The useful implication is that public managers should focus on continuous improvement process and renewal and OAO to meet stakeholders’ satisfaction.

Originality/value

This study answer two questions, first “is there any significant relationship of five factors of HPO framework with public organizations’ Performance in Pakistan?” and second “what is the predictive relevance level of HPO framework in the Public organizations in Pakistan?” The answers to these research questions will fill the gaps in the literature by providing empirical evidence to the existing knowledge on improvement methods, especially the public sector (PS), and contributing insights on the real world working of the five factors of HPO framework in a PS.

Abstract

Subject area

Operations and human resourcing.

Study level/applicability

This case study is intended for use in graduate, executive level management and doctoral programs. The case study illustrates a combined IT and HR driven participative management control system in a flexible organization structure. It is intended for a class discussion rather than to illustrate either effective or ineffective handling of an administrative situation.

Case overview

The case describes the situation of managing unskilled workforces (≥14,000 workers) during the construction phase of the 4 × 250MW power plants both for purposes of turnout as well as due compensation, in the event of an accident. The approved labour forces appointed for 45 × 8 h. Man-days after a rigorous fitness test and approvals of the safety officer are allocated housing and other necessary amenities and a commensurate compensation system.

Expected learning outcomes

These include: illustrating typical organizational responsibility structure at a construction site of a large power plant; illustrating the planning and administrative control mechanism in implementing strategy at a construction site of a large power plant; offering students the opportunity to understand and view a typical operational (project) structure; allowing students to speculate adaptations in the wake of an ever-changing business and company environment; and providing an opportunity to introduce a power scenario in India, Indian labour laws and radio frequency identification technology and to relate this to the case in context.

Abstract

Purpose

The purpose of this paper is to explore the factors that enable end‐user adoption of e‐government services in Pakistan, where these facilities are at a rudimentary stage.

Design/methodology/approach

Following previous research on e‐government services adoption, this study employs the Unified Theory of Acceptance and Use of Technology (UTAUT) model to examine the influential factors of the adoption and use of e‐government services in Pakistan from a citizen perspective. An online survey was conducted and a statistical descriptive analysis was performed on the responses received from 115 Pakistani citizens.

Findings

In line with previous research, the findings show that performance expectancy, effort expectancy, facilitating conditions and social influence are the factors that affect the user's adoption of e‐government services in Pakistan. Furthermore, the results show that lack of awareness, user data privacy, lack of appropriate support and assistance hamper the process.

Practical implications

The findings are useful for policy‐makers and decision‐makers to develop a better understanding of citizens' needs. The adopted model can be used as a guideline for the implementation of e‐government services in Pakistan. This study suggests that government should run extensive advertising campaigns to ensure that people are aware of the services and use them. This implies that government should place emphasis on increasing awareness of the services, show the benefits of citizens, and encouraging confidence in the system.

Originality/value

This study is one of the few to examine what influences citizens adoption of e‐government services in South Asia. This paper is the first step exploring end‐user adoption of the e‐government services of Pakistan using UTAUT model. Corresponding to previous research, this study enforces the significance of particular factors that need to be considered when the goal is to increase e‐government services adoption in developing countries, particularly South Asian.

Abstract

Purpose

The philosophy of the conservation resource theory, this paper aims to evaluate the relationship between humble leadership on project success by integrating the mediating role of psychological empowerment and the interacting effect of top management support on the direct relationship (humble leadership and project success), as well as indirect relationships through psychological empowerment.

Design/methodology/approach

Time lag data were gained from 337 persons working in the project-based organization across the information technology industry. Confirmatory factor analysis and structural equation modelling were used in this study.

Findings

By using the structural equation modelling method, the confirmatory factor analysis verified the uniqueness of the variable used in this research. The outcomes exhibited that humble leadership raised project success both directly and indirectly through mediation (psychological empowerment). Furthermore, Top management support was expected to have a moderating effect on the direct but not on the indirect relationship (via psychological empowerment).

Originality/value

This study demonstrates how top management support is essential for the project manager and project team members for the successful execution of the project. Particularly, minimal empirical research examines the interacting effect of top management support on humble leadership and employee psychological empowerment.

Abstract

Purpose

In rapidly changing global village, individuals, organizations and the society are faced with various unforeseen challenges every day, and these challenges continuously trigger and test the instincts for survival, and higher education is of no exception. In the context of today’s most critical uncertainty, i.e. COVID-19, the purpose of this study is to highlight the significance of two leadership styles, i.e. adaptive and academic leadership, and assessing readiness for change among higher education institutions (HEIs) of Punjab, Pakistan.

Design/methodology/approach

An online survey was conducted to collect data from 404 permanent faculty members in the public sector universities identified using stratified random sampling. The hypotheses developed were tested using co-variance-based structural equation modeling.

Findings

As per the findings, both leadership styles as exogenous constructs and the presence of organizational learning capability as mediators contributed positively in crafting organizational readiness for change (ORC) among HEIs in the course of unpredictable circumstances.

Practical implications

The COVID-19 episode globally has reiterated the importance of change, and the role of leadership in this regard cannot be undermined. This study, for that matter, stresses on the importance and benefits of academic and adaptive leadership dealing with uncertainties or change and the readiness of HEIs for change. Several institutions faced challenges in doing so, and the transition was not smooth, except for institutions where leaders were the differentiating factor. On top of it, institutions that had timely invested in digital systems and had enhanced organizations learning capacity survived in these turbulent times.

Originality/value

COVID-19 has placed tremendous challenges on HEIs to adapt with the rapidly changing conditions. Hence, this study is unique in understanding the academic and adaptive leadership styles in context of ORC. This study further helps in understanding that how public sector universities that are already influenced by stringent bureaucratic structures react to change.

Abstract

Purpose

The purpose of this study is to investigate the interaction effect of commercial loans in between trade Credit, retain earning, and entrepreneurial small and medium enterprises (SMEs) performance.

Design/methodology/approach

In this research, the cross-sectional research design was used, and data were collected from 362 SMEs located in Pakistan by using a questionnaire. Correlation and regression analysis was adopted to establish the interaction effect of commercial loans in between trade credits, retain earning and entrepreneurial SMEs performance.

Findings

The results demonstrated that commercial loans, trade credit and retain earning have a positive relationship with entrepreneurial SMEs performance. The findings also confirmed the interaction effect of commercial loans in between retain earnings, trade credit and entrepreneurial SMEs performance.

Originality/value

The study examined the association and interaction effect of commercial loans in between retain earnings, trade credit and SMEs performance in the emerging state (Pakistan). So, this is the first time to study the relationship between these variables, which highly contributes to entrepreneurial SMEs literature.

Abstract

Purpose

This study aims to review the growing research area of behavioral corporate governance; it explores the relationship between CEO duality attributes and earning management in the context of Asia-Pacific countries. Over time, the use by boards of chief executive officer (CEO) duality has fluctuated, and the scholarly conceptualizations of the phenomenon have become more complex.

Design/methodology/approach

This paper uses panel data from 330 firm years from Australia, Malaysia, The Philippines and Pakistan by taking a sample of three years from 2011 to 2013.

Findings

The results of the analysis reveal that the board leadership structure was not associated with firm performance and financial reporting quality. However, female CEOs impacted negatively on firm performance in Malaysia, The Philippines and Pakistan. Further analyses expose that the firm size was negatively related with performance, whereas established firms in Australia had strong reporting quality. However, large boards assured healthier reporting quality in Australia and Malaysia.

Practical implications

This paper provides empirical evidence that a unitary leadership pattern has no significant impact on companies in the Asia-Pacific, and it would be of interest to regulatory bodies, business practitioners and academic researchers.

Originality/value

This paper contributes to the literature on corporate governance and earnings management by introducing a framework for identifying and analyzing moderating variables that affect the relationship between the leadership structure and a firm’s financial reporting quality.

Abstract

Purpose

In this paper, the authors investigate that the increasing level of fossil fuel combustion in the industrial sector has been considered the prime cause for the emissions of greenhouse gas. Meanwhile, the research focusing on the impact of fossil fuel consumption on the emission of CO2 is limited for the developing countries containing Vietnam. This study applied the autoregressive distributed lag (ARDL) approach with structural breaks presence, and the Bayer–Hanck combined cointegration method to observe the rationality of the environmental Kuznets curve (EKC) hypothesis in the dynamic relationship between the industrialization and carbon dioxide (CO2) emission in Vietnam, capturing the role of foreign direct investment (FDI) inflows and the fossil fuel consumption over the period of 1975–2019. The outcomes revealed the confirmation of cointegration among the variables and both short and long-run regression parameters indicated the evidence for the presence of a U-shaped association between the level of industrial growth and CO2 emission that is further confirmed by employing the Lind and Mehlum U-test for robustness purpose. The results of Granger causality discovered a unidirectional causality from FDI and fossil fuel consumption to CO2 emission in the short run. For the policy points, this study suggests the use of efficient and low carbon-emitting technologies.

Design/methodology/approach

In order to test for consistency and robustness of the cointegration analysis, this study also applied the ARDL bound testing method to find out long-run association among variables with the existence of the structural break in the dataset. The ARDL method was preferred to other traditional cointegration models; because of the smaller dataset, the results obtained from the ARDL method are efficient and consistent and equally appropriate for I(1) and I(0) variables.

Findings

The short-run and long-run causal associations among variables have been observed by employing the error correction term (ECT) augmented Granger-causality test that revealed the presence of the long-run causality among variables only when the CO2 emission is employed as a dependent variable. The outcomes for short-run causality indicated the presence of unidirectional causality between consumption of fossil fuel and CO2 emission, where the fossil fuel consumptions Granger-cause CO2 emission. Industrial growth has also been found to have an impact on fossil fuel consumptions, however not the opposite. This advocates that the policies aimed at reducing the fossil fuel consumptions would not be harmful to industrial growth as other energy efficient and cleaner technology could be implemented by the firms to substitute the fossil fuel usage.

Originality/value

The study explored the dynamic relationship among FDI, consumption of fossil fuel, industrial growth and the CO2 emission in Vietnam for the time period 1975–2019. The newly established Bayer–Hanck joint cointegration method and the ARDL bound testing were employed by taking into account the structural breaks in the dataset.
