Abstract

Purpose

The satellite pointing accuracy plays a crucial role in ensuring a successful satellite mission itself. Therefore, this paper aims to enhance the attitude pointing accuracy of the combined energy and attitude control system (CEACS) in a satellite in the presence of external disturbance torques through a robust controller, which can produce high pointing accuracies with smaller control torques.

Design/methodology/approach

To improve the CEACS attitude pointing accuracy, a maiden fuzzy proportional derivative (PD)-based CEACS architecture is proposed. The mathematical models along with its numerical treatments of the fuzzy PD-based CEACS attitude control architecture are presented. In addition, a comparison between the PD and fuzzy PD controllers in terms of the CEACS pointing accuracies and control torques is provided.

Findings

Numerical results show that the fuzzy PD controller produces a considerable CEACS pointing accuracy improvement for a lower control torque compartment.

Practical implications

CEACS has gained a renew interest because of significant increase in the projected onboard power requirements for future space missions. Therefore, it is of paramount importance to improve the CEACS pointing accuracy itself with a minimum control torque compartment. In fact, this proposed fuzzy PD controller is shown to be a potential CEACS attitude controller.

Originality/value

The fuzzy PD-based CEACS architecture not only provides a better attitude pointing accuracy but also ensures a lower control torque compartment, which corresponds to a lower onboard power consumption.

Abstract

Purpose

The purpose of this paper is to formulate a benchmark to increase the tyre curing press production rate while minimizing tyre curing press downtime and maintenance cost with the help of a maintenance management technique based on overall equipment effectiveness (OEE).

Design/methodology/approach

The methodology is based on determining the OEE of tyre curing press before and after rectifying the causes of failures. The failure mode and effect analysis (FMEA) technique is used to find out the root causes of repetitive failures in tyre curing press by using the risk priority number.

Findings

A significant change in the value of OEE is observed after rectifying the repetitive failures, which were determined using the FMEA technique. Thus, it is concluded that the OEE and FMEA assist in improving the industrial performance and competitiveness of the production equipment studied.

Research limitations/implications

This study is limited to determining the OEE of single equipment only, not the whole production system. Manufacturing facilities are dependent on the operating environment; therefore a comparison of two different manufacturing plants based on the OEE value would not be justified.

Practical implications

This study can be applied in any tyre manufacturing industry in order to take competitive benefits, such as reduction in equipment downtime, increased production and reduction in maintenance cost.

Originality/value

The angle from which the paper approaches the bottleneck problem in a tyre production line is original for the studied company and shows positives results. It allows the company to apply the same approach in its other production equipment, lines and factories to achieve improvement in industrial performance and competitiveness.

Abstract

Purpose

The purpose of this study is to investigate the impact of integrating “Licorice powder” into curd balls on their storage stability under refrigeration conditions. Through this examination, this study aims to evaluate the potential effects of licorice powder on extending the shelf life, maintaining quality attributes and preserving the overall stability of curd balls when stored at refrigeration temperatures.

Design/methodology/approach

Licorice powder, in varying quantities (1%, 2% and 3%), was incorporated into curd balls alongside a control group lacking licorice (0%). These batches were subsequently stored for 25 days under refrigeration at a temperature of 4 ± 1ºC, using aerobic packaging conditions. During this storage period, the samples were regularly monitored and analyzed for various parameters to assess changes in their properties and qualities.

Findings

The findings indicated that in the treatment groups, pH and titratable acidity were notably lower than those in the control group (p = 0.05). Curd balls enriched with licorice powder exhibited significantly higher levels of 2, 2-diphenyl-1-picrylhydrazyl, 2-2-azinobis-3ethylbenthiazoline-6-sulphonic acid and total phenolic contents compared to the control (p = 0.05). Furthermore, curd balls containing licorice powder displayed notably lower levels of peroxide, thiobarbituric acid reactive substances and free fatty acids in comparison to the control (p = 0.05). Among all samples, T3 (3%) demonstrated significantly less microbial growth (p = 0.05) than the other groups. Conversely, the sensory panel rated T2 significantly higher than T3 (p = 0.05).

Originality/value

The investigation highlights that curd balls enriched with 2.0% licorice powder demonstrated significant efficacy in preventing the deterioration of physicochemical attributes, enhancing antioxidant capacity, restraining lipid oxidation, curbing microbial growth and ultimately exhibiting the most favorable organoleptic properties among the tested variations. This finding underscores the potential of incorporating 2.0% licorice powder as an effective agent for bolstering the storage stability and overall quality of curd balls during refrigerated storage.

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 emergence of the COVID-19 epidemic has considerably increased the intricacy of information, exacerbating the difficulties firms encounter in efficiently processing and understanding accurate data and knowledge. Consequently, the COVID-19 epidemic has profoundly exacerbated production ambiguity for firms, thereby disrupting their regular business operations and supply chain activities. Digital technologies (DTs) are essential tools for firms to process and interpret information and knowledge, thereby improving their resilience against supply chain interruptions.

Design/methodology/approach

This research investigates the effect of digital technologies on firm resilience throughout COVID-19, utilizing PLS-SEM and artificial neural networks (ANN) derived from a comprehensive survey of Pakistani manufacturing firms.

Findings

Our research assesses the mediating role of supply chain integration, memory, and absorptive capacity, as well as the moderating influence of information complexity. The outcomes demonstrate that supply chain integration (SCI), memory (SCM), and absorptive capacity (SCAC) mediate digital technologies’ influence on firm resilience. Moreover, in situations where information is highly complex, DTs have a greater effect on a firm’s resilience.

Originality/value

The results enhance our comprehension and awareness of the resilience-related effects of DTs and offer significant management insights for strengthening firm resilience in the setting of the COVID-19 pandemic.

Abstract

Purpose

The purpose of this paper develops a conceptual model of social influence for Internet banking adoption (IBA) using social networking platforms (SNPs). It identifies the antecedents of social influence that can positively and negative influence the IBA among a targeted population of conventional and Islamic banks. Moreover, this paper contributes various factors to social influence theory with the purpose of enhancing its implication in the context of Internet banking uptake in developed and developing countries.

Design/methodology/approach

This study uses a social constructivism approach to understand customer experiences, thoughts, knowledge, awareness and perceptions in relation to IBA. For this study, data were collected from 30 respondents using semi-structured interviews and purposive sampling.

Findings

Social influence comprises customer recommendations, suggestions, ratings, reviews, experiences and thoughts regarding the IBA of Islamic and conventional banks. The findings reveal that social reviews, social experts, social consensus, social responsibility and social perceptions are the key antecedents of social influence that can enhance IBA of SNPs. The research finds that positive social reviews, expert support, consensus, social responsibility and social perceptions are significant in relation to conventional Internet banking. The respondents revealed serious concerns about the privacy of their personal and financial information especially in relation to Islamic banks.

Research limitations/implications

The effective and well-organized use of SNPs can foster service reviews, word of mouth, higher levels of service awareness, interactive communication, social consensus and social trust to drive the adoption of Internet banking. This study proposes the conceptual model which has positive business implications and provides the banks direction to use the SNPs to their advantage to influxes their customers to adopt the use of Internet banking.

Originality/value

Most previous studies have used technology acceptance model, theory of planned behavior and unified theory of acceptance and the use of technology theories in the adoption of technology and IBA. These theories have not fully illuminated the role of social content as a way to enhance or decrease the number of customers in conventional and Islamic banks. This study develops social influence theory by exploring several dimensions (i.e. social reviews, awareness, consensus, cooperation and experts support) in the context of IBA for users of SNPs. Social influence can create more reviews and can lead to more prepurchase information. It can drive customer inquiries and engagement and can inform purchase decisions for IBA. On the other hand, it can motivate existing customers of Islamic banks to use conventional banking services due to effective word of mouth.

Abstract

Purpose

Talent management research today is increasing as organizational requirements attempt to meet the challenges of effectively managing talent to achieve organizations’ strategic agendas. However, in learning organizations specifically, investigations of talent management practices are limited, with this study exploring the role of talent management practices in employee satisfaction and organizational performance in Pakistan.

Design/methodology/approach

The study was conducted in various universities (public and private) in Pakistan using a quantitative approach. Cross-sectional data are collected through a questionnaire, with analysis and conclusions based on completed questionnaires from 403 respondents.

Findings

The study’s findings from the analysis by structural equation modeling (SEM) emphasize the positive and significant effects of most talent management practices (i.e. talent identification, talent development, talent culture and talent retention) on employee satisfaction and organizational performance (talent attraction is the exception). Employee satisfaction positively and significantly affects organizational performance and is found to have a mediating effect, bridging the relationships of most talent management practices (talent identification, talent development, talent culture and talent retention) with organizational performance.

Practical implications

The study’s findings support human resource professionals, academics and policymakers in managing talent practices to enhance organizational performance. The findings assist in developing core skills and talent-related competencies to achieve organizational goals and success.

Originality/value

The study fills the research gaps by developing a framework of talent management practices for employee satisfaction and organizational performance in learning organizations, which warrants further consideration.

Abstract

Purpose

This study aims to explore how institutional quality links digital financial inclusion to inclusive development in lower-middle-income countries, considering heterogeneities.

Design/methodology/approach

The study uses dynamic generalized method of moments to analyze a balanced panel data set of 48 lower-middle- income countries (LMICs) from 2004 to 2022, sourced from various databases. It assesses four variables and conducts checks for study robustness.

Findings

The study reveals a positive link between digital financial inclusion and inclusive development in LMICs, confirming theoretical predictions. Empirically, nations with quality institutions exhibit greater financial and developmental inclusion than those with weak institutions, emphasizing the substantial positive impact of institutional quality on the connection between digital financial inclusion and inclusive development in LMICs. For instance, the interaction effect reveals a substantial increase of 0.123 in inclusive development for every unit increase in digital financial inclusion in the presence of strong institutions. The findings provide robust empirical evidence that the presence of quality institutions is a key catalyst for the benefits of digital finance in inclusive development.

Originality/value

This study offers significant insights into digital financial inclusion and inclusive development in LMICs. It confirms a positive relationship between digital financial inclusion and inclusive development, highlighting the pivotal role of institutional quality in amplifying these benefits. Strong institutions benefit deprived individuals, families, communities and businesses, enabling full access to digital financial inclusion benefits. This facilitates engagement in development processes, aiding LMICs in achieving Sustainable Development Goals.
