The purpose of this study was to investigate the determinants of purchase intentions for utilitarian and hedonic counterfeit sporting goods among Muslim’ consumers. The moderating effect of income and status consumption was also examined.

Questionnaires were distributed among male undergraduate university students who were consumers of sports goods. A total of 360 valid and usable questionnaires were collected and analyzed through descriptive and inferential statistics.

The results showed that perceived risk, personal gratification, religiosity, information susceptibility and normative susceptibility all have a positive and significant effect on negative attitudes toward counterfeit sports goods. The effect of a negative attitude toward counterfeit goods was also negative and significant for the intention to purchase utilitarian and hedonistic goods. Income was not a moderator in the relationship between negative attitudes and the intention to purchase utilitarian and hedonic goods. However, the moderating effect of status consumption on the intention to purchase both utilitarian and hedonic goods was significant.

The use of a male-only student sample potentially limits the generalization of the findings, but not the underlying relationships between the variables. Efforts to discourage or prevent the purchase of counterfeit sporting goods should highlight the risk and reduced personal gratification associated with purchasing counterfeit products, while also appealing to a person’s faith-based ethics.

This study produces a novel model explaining the purchase intentions for utilitarian and hedonic counterfeit sporting goods. This model can inform the development of anti-counterfeiting strategies in Muslim countries.

This study aims to investigate drivers of co-branding, and the relative strength of these drivers within the Persian Gulf Pro League (PGPL). The study examines sport sponsorship, and specifically the relationship between professional football teams and on-field apparel sponsors.

Sixteen experts participated in semi-structured interviews and ranked the co-branding drivers. The expert opinions were organized into estimates and triangular fuzzy numbers were established before the Mamdani Fuzzy Inference System converted the fuzzy outputs into crisp output values using the Centroid method. Next, the rankings of the drivers by the same 16 participants were analyzed using the analytical hierarchy process (AHP).

The study identified four main factors with 19 indicators: brand management (i.e. enhancing brand value, utilizing the knowledge and experience of partner brands, brand position, brand identity, brand equity and brand image), partner relationships (i.e. satisfaction, mutual trust, commitment, common interest, product reliability and innovative strategies), marketing factors (i.e. marketing mix, market position, competitive advantage and entry into new domestic markets) and supporting factors (i.e. copyright, contracts and social media law). The AHP identified the most influential factors as marketing, partner relationships, brand management and support.

Based on the study’s findings, the authors recommend that PGPL teams adopt a partnership mindset, seek alignment of values and recognize the plurality of stakeholders to a sponsorship and their relationships to each other. The study highlights the challenges of co-branding activities in a developing country where trademark laws are not well developed.

The purpose of the study was to compare young adult responses to rational and emotional sports product advertisements. The moderating roles of product type and gender were also examined.

The study utilized a 2 (advertising appeal: emotional vs rational) ×2 (gender: male vs female)×2 (sport product type: utilitarian vs hedonic) research design. Data were collected from 160 sport product users. The collected data were analyzed using three-way analysis of variance (ANOVA).

The results indicated that emotional advertising has a greater impact on the attitude toward advertising and the intention to purchase sports products. The results also revealed that rational advertising appeals have more impact for utilitarian sports products and that emotional advertising appeals are more effective for hedonic sports products. However, there were no significant effects for gender as a moderating variable.

This is the first study to examine responses to rational and emotional appeals in sports product advertisements.

The aim of this paper is to investigate the interaction effect that sponsor-team congruence and team fan (home/rival team) have on the influence of different types of sports sponsorship (joint, corporate social responsibility [CSR]-linked and conventional sponsorship) on fans' attitudes and purchase intentions toward the sponsor.

Two experimental studies were conducted on 391 and 297 participants. The data gathered underwent analysis through five multivariate general linear model analyses.

The study found that CSR-linked sponsorship had the strongest positive impact and the weakest negative impact on the attitude and purchase intention of home team supporters and the attitude of rival team supporters. Nonetheless, the sponsor-team congruence did not significantly moderate the relationship. Additionally, the research demonstrated that the fan identity of both home and rival teams moderates the impact of sports sponsorships on attitude and purchase intention.

Previous research has studied the effectiveness of sponsorship format types independently. This is the first research comparing sponsorship formats regarding fan type and congruence.

Athlete brand image management has become a popular topic among sport marketing scholars. This study aims to test the impacts of the attributes of an athlete brand image on fan loyalty.

In total, 500 questionnaires were delivered to university students and 472 completed questionnaires were returned. Confirmatory factor analysis was conducted to test the psychometric properties of the measures and structural equation modeling was carried out to test the hypotheses.

The findings of this study show that three attributes of athlete brand image (e.g. marketable lifestyle, athletic performance and attractive appearance) positively influenced fan loyalty.

To increase the loyalty of fans, effective marketing strategies could be designed to create positive images of athletes with both athletes’ on-field (e.g. athletic skills, competition style and excellence in sport) and off-field performance (e.g. engagement with fans, community involvement, public relation and charity activities).

This paper provides valuable insights into the measurement of athlete brand image and fan loyalty and offers a foundation for future research on athlete brand management.

The main objective of the paper is to explore the theoretical correlation of base oil viscosity in grease and to study the effect of grease grade on mechanical vibrations associated with the damaged rolling bearings.

For theoretical purposes, formulation theory of dimensional analysis was implemented. Experiments were then performed on the test bearings lubricated with three different types of greases, namely, SKF LGHP2, SKF LGMT3 and SKF LGWA2.

The numerical results obtained from the theoretical model along with the results of experiments show that the vibration amplitudes of the defective bearings come down to a lower level when it is lubricated with the grease of a higher base oil viscosity.

The promising results from the theoretical model make it usable for the practical rotating machineries applying a variety of the rolling bearings. Consequently, if the bearing is not severely damaged, its performance can be increased by lubricating it with thicker grease.

Despite many significant contributions in the field to detect the presence of defects, not many studies have been performed that relate the lubrication condition of the rolling bearings with the vibration response, because around 50-75% of the bearing failures are attributed to be lubrication related. Hence, there is need to develop a mathematical model that can correlate the vibration severity of the bearings with viscosity of the lubricant oil in the greases along with other design and operating parameters.

This study aims to analyze the volatility spillover effects of crude oil, gold price, interest rate (yield) and the exchange rate (USD (United States Dollar)/INR (Indian National Rupee)) on inflation volatility in India.

This study uses the multivariate Generalized Autoregressive Conditional Heteroscedasticity (GARCH) models (Baba, Engle, Kraft and Kroner [BEKK]-GARCH and dynamic conditional correlation [DCC]-GARCH) to examine the volatility spillover effect of macroeconomic indicators and strategic commodities on inflation in India. The monthly data are collected from January 2000 till December 2020 for the crude oil price, gold price, interest rate (5-year Indian bond yield), exchange rate (USD/INR) and inflation (wholesale price index [WPI] and consumer price index [CPI]).

In BEKK-GARCH, the results reveal that crude oil price volatility has a long time spillover effect on inflation (WPI). Furthermore, no significant short-term volatility effect exists from crude oil market to inflation (WPI). However, the short-term volatility effect exists from crude oil to inflation while considering CPI as inflation. Gold price volatility has a bidirectional and negative spillover effect on inflation in the case of WPI. However, there is no price volatility spillover effect from gold to inflation in the case of CPI. The price volatility in the exchange rate also has a negative spillover effect on inflation (but only on CPI). Furthermore, volatility of interest rates has no spillover effect on inflation in WPI or CPI. In DCC-GARCH, a short-term volatility impact from all four macroeconomic indicators to inflation is found. Only crude oil and exchange rate have long-term volatility effect on inflation (CPI).

In an economy, inflation management is an essential task. The findings of the current study can be beneficial in this endeavor. The knowledge of the volatility spillover effect of all the four markets undertaken in the study can be significantly helpful in inflation management, especially for inflation-targeting policy.

It is observed that no other study has addressed this issue. We do not find any other research which studies the volatility spillover effect of gold, crude oil, interest rate and exchange rate on the inflation volatility. The current study is novel with a significant contribution to the vast knowledge in this context.

The work on bridge resilience assessment includes quantitative and qualitative approaches to compare the multiple bridges based on their resilience. But still, the bridge resilience obtained by these assessment approaches is inefficient when prioritising multiple bridges to improve their resilience. Therefore, this study aims to develop a methodology for prioritising the bridges to improve their resilience.

The research methodology follows three sequential phases. In the first phase, criteria importance through intercriteria correlation (CRITIC) technique is used to compute the criteria weights. The criteria considered are age, area, design high flood level, finish road level FRL and resilience index of bridges. While 12 river-crossing bridges maintained by one bridge owner are considered as alternatives. Then, in the second phase, the prioritisation of each bridge is evaluated using five techniques, including technique for order of preference by similarity to ideal solution, VIKOR (in Serbian, Visekriterijumska Optimizacija I Kompromisno Resenje), additive ratio assessment, complex proportional assessment and multi-objective optimisation method by ratio analysis. Finally, in the third phase, the results of all five techniques are integrated using CRITIC and the weighted sum method.

The result of the study enables bridge owners to deal with the particular bridge that requires resilience improvement. The study concluded that it is not enough to consider only the bridge resilience index to improve its resilience. The prioritisation exercise should consider various other criteria that are not preferred during the bridge resilience assessment process.

The proposed methodology is a novel framework based on the existing multi-criteria decision-making (MCDM) techniques for contributing knowledge in the domain of bridge resilience management. It can efficiently overcome the pitfall of decision-making when two bridges have the same resilience index score.

This paper aims to focus on studying the influence of gradient parameters, namely, thickness coefficient, length coefficient and height ratio of auxetic structure on responses such as strength, stiffness and specific energy absorption (SEA) under compressive loading. Optimization of significant parameters is also performed to maximize responses. Further, efforts have also been made to develop regression models for strength, stiffness and SEA of auxetic structure.

Central composite design of response surface methodology is used for planning experiments. Auxetic structures of acrylonitrile butadiene styrene (ABS) and poly-lactic acid (PLA) materials are fabricated by the material extrusion (ME) technique of additive manufacturing. Fabricated structures are tested under in-plane uniaxial compressive loading. Grey relational analysis is used for the optimization of gradient parameters of the unit cell of auxetic structure to maximize responses and minimize weight and time of fabrication.

From the analysis of variance of experimental data, it is found that the compressive strength of auxetic structures increases with a decrease in length coefficient and height ratio. In the case of ABS structures, stiffness increases with a decrease in thickness coefficient and length coefficient, while in the case of PLA structures, stiffness increases with a decrease in length coefficient and height ratio. SEA is influenced by length coefficient and thickness coefficient in ABS and PLA structures, respectively. Based on the analysis, statistical non-linear quadratic models are developed to predict strength, stiffness and SEA. Optimal configuration of auxetic structure is determined to maximize strength, stiffness, SEA and minimize weight and time of fabrication.

The present study is limited to re-entrant type of auxetic structures made of ABS and PLA materials only under compressive loading. Also, results from the current study are valid within a selected range of gradient parameters. The findings of the present study are useful in the optimal selection of gradient parameters for the fabrication of auxetic structures of maximum strength, stiffness and SEA with minimum weight and time of fabrication. These outcomes have wide applications in domains such as automotive, aerospace, sports and marine sectors.

Limited literature is available on studying the influence of gradient parameters of ME manufactured auxetic structure of ABS and PLA materials on responses, namely, strength, stiffness and SEA under compressive loading. Also, no work has been reported on studying the influence of gradient parameters on mechanical properties, weight and time of fabrication of auxetic structures. The present study is an attempt to fulfil the above research gaps.

Mental health problems during the initial years of life are precursors of mental disorders in later life, as well as poor quality of life. However, understanding and assessing the quality of life among children is very challenging and requires appropriate assessment measures. Against this backdrop, this study aims to establish the evidence for the construct and convergent validity of Urdu version of Pediatric Quality of Life Inventory (PedsQL) in Pakistani children.

This study has a cross-sectional study design in which a sample of 291 primary school children (53.3% male children and 44.7% female children) were enrolled from 6 primary schools located in Rawalpindi District in 2021 through random sampling. Children’s ages ranged between 9 and 13 years (M = 10.51 years; SD = 0.73). Urdu translated version PedsQL, Rosenburg self-esteem scale (RSES), strengths and difficulties questionnaire (SDQ), difficulty subscale and socio-demographic form were administered in a group setting.

Confirmatory factor analysis showed model provided a better fit similar to three factors: social/school functioning; psychological functioning; and physical functioning with good alpha reliability for full scale as well for subscales (r = 0.87, r = 0.75, r = 0.77 and r = 0.73), respectively. Pearson’s correlation of the translated version with SDQ_difficulties (r = −0.33; p < 0.01) and RSES (r = −016; p < 0.01) depicted solid discriminant validity (r = −0.33; p < 0.01) and RSES showed good convergent validity (r = −0.16; p < 0.01). Hence; PedsQL, Urdu proved to be a reliable, valid and efficient tool for the assessment of quality of life among Pakistani children, and its three-factor structure model suggested previously for Pakistani children was confirmed.
