Does government support enhance the relation between networking structure and sustainable competitive performance among SMEs?
No full textPurpose: The underlining study's main objective is to examine how networking structure (density and centrality) affects sustainable competitive performance in Pakistan's SMEs. Design/methodology/approach: Hence, small enterprises a significant source of economic development, employment, and value creation. Therefore, on the base of previous literature, we developed hypothesis related government financial support and network structure, and data collected through structured questionnaires from top management of SMEs. Findings: The results indicate that density has a positive and significant effect on sustainable competitive performance, while centrality has an insignificant impact on SCP. Furthermore, government financial support strongly and significantly supports the relation between networking structure and SCP in Pakistan. Practical implications:This research has several recommendations for the government to adequately support small enterprises because owners have a networking system at the local and international level but have a lack of environment. Originality/value:Government plays a crucial role in small- and medium-sized enterprises boost performance and economic growth because it creates employment opportunities, poverty reduction, and economic development. Nevertheless, from the last decades, due to some organizational policies and environmental flexibility, SMEs face a lot of challenges which became a barrier such as lack of government subsidies, incentives, and taxes in emerging economies. To bridge the above challenges of SMEs, the current study is conducted because before this there was no such literature who underline the current challenges in emerging economies
The Impact of Customer Relationship Management and Company Reputation on Customer Loyalty: The Mediating Role of Customer Satisfaction
No full textFactors affecting women entrepreneurs' success: A study of small- and medium-sized enterprises in emerging market of Pakistan
No full textIn the present era, women are recognized as successful entrepreneurs through their strong desire, qualities, and capabilities for robust economic development. Due to such an important contribution of women in economic development, we propose to investigate the factors which affect women entrepreneur's success in Pakistan. Data were collected through structured questionnaires from 181 registered SMEs operating in Pakistan. A conceptual model is developed, while SPSS and AMOS software's are used for analysis. The results indicate that the internal factors including the need for achievements, risk-taking, and self-confidence and external factors including economic factors and socio-cultural factors have a positive and significant influence on the success of women-owned enterprises. This research recommends Small and Medium Enterprises Development Authority (SMEDA), policymakers, and practitioners to encourage women entrepreneurs to run their businesses for the long term by providing a variety of incentives and supports related to those internal and external factors. Numerous studies have been conducted to test the different factors' effects on women's entrepreneurial success, but our study investigated some psychological, cultural, and religious factors that are still almost untouched especially in Pakistan. The current study also contributes to the existing literature through empirical shreds of evidence
Prevention of Cryptojacking Attacks in Business and FinTech Applications
No full textMore than 2000 different cryptocurrencies are currently available in business and FinTech applications. Cryptocurrency is a digital payment system that does not rely on banks to verify their financial transactions and can enable anyone anywhere to send and receive their payments. Crypto mining attracts investors to mine and gets some coins as a reward for using the cryptocurrency. However, hackers can exploit the computing power without the explicit authorization of a user by launching a cryptojacking attack and then using it to mine cryptocurrency. The detection and protection of cryptojacking attacks are essential, and thus, miners are continuously working to find innovative ways to overcome this issue. This chapter provides an overview of the cryptojacking landscape. It offers recommendations to guide researchers and practitioners to overcome the identified challenges faced while realizing a mitigation strategy to combat cryptojacking malware attacks

The designed FSS is showing stop band transmission characteristics below −10 dB threshold from 25 GHz to 42 GHz and 59 GHz to 61 GHz. The eight element antenna integrated with the FSS reflector, which results an improvement in the gain level from 12 dB to 15 dB at 28 GHz, from 10 dB to 12 dB at 38 GHz, and from 9.5 to 11 dB at 60 GHz. The dimensions of the antenna are 65 × 27 × 0.857 mm3. The proposed antenna shows stable gain and directional radiation patterns. The simulation findings are experimentally confirmed, by testing the fabricated prototypes of the proposed antenna system
Partial Discharge Characterization of HFO(E) Gas Using Ultra-High Frequency (UHF) Antenna for Medium Voltage Switchgear Application
No full textThe most frequent and dangerous hazard to the electrical insulation of high voltage (HV) and high field (HF) equipment is partial discharges (PD). The development of PD activity is both a cause and an indicator of insulation degradation, which could ultimately lead to insulation breakdown. For electrical power equipment to operate safely and dependably, continuous and efficient PD monitoring must be conveniently performed to prevent associated damages and any harm to electrical power equipment. This work presents the design of a new UHF antenna for detecting PD in medium-voltage gas-insulated applications. The working
frequency band of the proposed UHF antenna is 370 MHz–1300 MHz, which translates into a total bandwidth of 930 MHz UHF frequency band. Over the whole operating frequency of the antenna, the return loss is less than -10dB. Recently, an eco-friendly insulating gas, HFO1336mzz(E), is considered to be a good substitute for sulfur hexafluoride (SF6) in medium-voltage gas-insulated equipment (MV-GIE). The HFO(E) gas in
a mixture with CO2 can reach the dielectric strength of SF6 gas. Hence, the HFO(E)/CO2 gas mixture’s partial discharge properties are systematically investigated in this research work. In particular, a detailed examination focuses on the partial discharge extinction voltage (PDEV) and partial discharge inception voltage (PDIV) under varying electric field conditions at different gas pressure levels and mixing ratios. The PDIV of the HFO(E)/CO2 gas mixture exhibited a linear-saturation rising pattern with both mixing ratio and
gas pressure, mirroring the trend observed in SF6 when the HFO(E) gas concentration ranged between 25% and 30%
Entrepreneurial Orientation and Small and Medium-sized Enterprises’ Performance; Does ‘Access to Finance’ Moderate the Relation in Emerging Economies?
No full textThe main objective of the underline study is to examine the influence of entrepreneurial orientation (EO) on financial and non-financial performance of small and medium-sized enterprises (SMEs) with the moderating role of access to finance. Because SMEs—due to fair reasons such as lack of resources and lack of managerial skill—are often unable to succeed in their mission, the managers look for much less risky and convenience factors to compete in the market. A variety of factors has been tested but the role of finance in this perspective has received minor attention. Hence, the underline study tested finance as a moderator between firm resources and their performance. To test the model, a structured questionnaire is used to collect data from 326 Pakistani SMEs. Structural equation modelling in AMOS is used to test the hypotheses. Our finding suggests that EO significantly enhances SME’s financial and non-financial performance in emerging economies. On the other hand, access to finance significantly moderates the relationship between EO and SME’s financial performance, while it is not significantly moderating between EO and non-financial performance.
This research recommends policymakers and practitioners to focus on accessing adequate finance while the Small and Medium-sized Enterprises Development Authority encourages banks and financial institutions to facilitate SMEs. Furthermore, the possible implications have been discussed

Exploring the Effects of Gamification in Assisting Students Maintain a Better Work-Life Balance
No full textThe concept of work-life balance has become difficult for students to grasp in a world where the distinction between work and other activities in life is a blur. The aim of the study was to investigate the effects of gamification in apps on student’s perceived work-life balance. Participants were divided into a gamified app group and a non-gamified app group and were given online questionnaires before and after the experiment, which lasted two weeks. Several data analysis methods were adopted such as descriptive statistics, inferential statistics, and thematic analysis. While the non-gamified app group experienced a greater positive change in perceived work-life balance, the gamified app group showed higher satisfaction in work-life balance. Gamification did not significantly affect autonomy and competence satisfaction but increased relatedness satisfaction and engagement levels. Rewards and achievements were identified as the most effective game elements. Further research is needed to explore the effects of gamification on work-life balance in-depth as research on gamification continues to expand.</p
The Insulation Performance of Novel Refrigerant Gas as an Alternative to SF6 for Medium Voltage Switchgear
No full textGas-insulated systems are widely utilized in the electric power sector to transmit and distribute electrical energy. Sulphur-hexafluoride (SF6) has dominated gas insulation in high-voltage insulation technology since the early 60s. It is a greenhouse gas with a protracted lifespan in the atmosphere. This paper proposes an economical and comparatively more environmentally friendly R507 gas alternative to SF6 for
medium-voltage applications. R507 has been analyzed experimentally through power frequency breakdown and lightning impulse testing to validate the performance and theoretical concepts. R507 has a very low liquefication temperature of −46.7◦C, but it must still be mixed with buffer gases such as CO2, N2, or dry air to meet the diverse liquefaction temperature applications. Various field utilization factors under AC and lightning impulse voltages are used in the experiments, along with different electrode geometries, including sphere-to-plane and rod-to-plane (i.e., quasi-homogeneous and inhomogeneous electric field distribution).
For comparison, identical experiments are conducted with pure SF6. R507 gas was found to be a promising substitute for SF6 gas, with its dielectric strength being approximately 0.95 times that of SF6 gas. A positive synergistic effect is present between R507 and CO2, along with the good self-recoverability property of the gas mixture. The current research study serves as a fundamental resource for characterizing the R507/CO2 gas mixture insulation properties to be utilized in practical applications
