Although multinational enterprises (MNEs) based in emerging economies arose quickly during the past decade, most of these firms lack marketing capabilities and strong brands. Emerging-economy MNEs that have tried to build their own brands have been largely unsuccessful. The purpose of this paper is to argue that corruption in the MNEs’ home countries has been detrimental to their brand values. Corruption makes it more difficult for consumers to govern their transactions with local firms, thus decreasing firms’ trustworthiness and brand values.

Data of the global top 500 most valuable brands of 2008 and 2014 and the Poisson regression model are used.

This study finds that firms based in countries with lower levels of corruption establish more valuable brands than those based in countries with higher corruption, even when GDP and GDP per capita are controlled.

Policymakers who want to help local firms increase their marketing capabilities and establish strong brands should strive to increase the trustworthiness of local firms by undertaking anti-corruption reforms aimed at protecting consumers.

Few studies have address the research question that why emerging-market MNEs lack marketing capabilities and strong brands. This study finds that institutional factors such as corruption at country level prevent them from establishing strong brands.

The purpose of the study is to investigate, synthesize and critically evaluate empirical research findings on the behavioral traits of fund managers from 1994 to 2024. The ultimate goal is to provide a unified body of literature on three broad topics: first, fund managers' demographic and professional characteristics, such as age, gender, level of education and years of industry experience; second, fund managers' social and political connections; and third, fund managers' behavioral biases that lead to irrational investment decisions.

The relevant papers from selected journals were discovered and manually validated using the Scopus database. From 317 retrieved documents, 57 relevant articles were chosen and analyzed after the forward and backward search of the existing articles.

This paper presents a categorized summary of behavioral factors that have gained a foothold in influencing the behavior of fund managers in fund management research, with several studies demonstrating their significance leading to improved prediction and model precision, as this review indicates. In addition, the study summarized the contributions of prior empirical studies within the aforementioned three major categories and illustrated their consequences.

The present study contributes to the understanding of the effects of behavioral finance theories on fund managers by providing meaningful explanations of their behavioral traits based on empirical evidence and existing trends and knowledge gaps, both of which can influence the future direction of research.

Relativism, at least in some of its forms, is antithetical to sociology as traditionally practiced and conceived. (See, for instance, Benton and Crabb, 2001, pp.50‐74 and 93‐1006; Collins 1996a; Mann, 1998; Murphy, 1997; and Taylor‐Gooby, 1994). Hence, sociologists should consider abandoning traditional sociology or rejecting relativism. An example of the sort of relativism I have in mind is the philosophical theory that the truth and falsity of propositions is relative to the social context of their promulgation. Such epistemological relativism is expressed by Newton‐Smith when he says: “The central relativist idea is that what is true for one tribe, social group or age might not be true for an other tribe, social group or age” (Newton‐Smith, 1982, p.107).

This paper aims to investigate how students’ attitude (SA), students’ subjective norms (SN), students’ knowledge sharing intentions (KSI) can contribute to the enhancement of knowledge sharing behaviour (KSB) among students at higher education institutes (HEI) in Oman.

This study follows the quantitative methodology and the deductive causal research approach. The data were conveniently collected through a Web-based questionnaire (Google forms) from 285 active students who are affiliated to Omani universities. SPSS was used to statistically analyse the collected data, including partial least square-structural equation modelling (PLS-SEM V3.3) to draw the results.

The study concluded that SA has both direct and indirect positive impact on SN, KSI and KSB. Moreover, the result revealed that there is a mediation effect between SA and KSB through KSI, SA and KSI when SN is playing as a mediation role.

Although this study contributes to the existing body of knowledge, this study is limited by the scarcity of the related literature in the Omani context. It is recommended that these shortfalls be addressed together while improving the knowledge-sharing behaviour among students and administrative staff. Furthermore, the potential variation between academic staff and students in terms of factors affecting their intentions to share knowledge within HEIs should be explored.

This research provides policymakers in academic fields with the appropriate approaches to leverage the knowledge-sharing behaviour amongst Omani students with the understanding of the main factors affecting individuals’ knowledge-sharing behaviours.

This will help in improving the means of employing and practising knowledge-sharing strategies within HEIs, which can generate competitive advantages amongst students and institutions while benefiting knowledge management strategies and its members.

The importance of the study stems from its context being conducted in Oman as a developing country. In addition, this study is one of the initial attempts to investigate KSB by considering SA, SN and KSI and its applicability on HEI in Oman. The findings of the study can serve as inputs to HEI in developing best practices across KSB dimensions and expanding the knowledge-sharing culture amongst HEI’s students in Oman. One of the developed strategies is the spreading of the knowledge-sharing culture among students by positively directing their attitude towards the practices of knowledge exchange.

The purpose of this paper is to estimate the performance of Brazilian hospitals’ services and to examine contextual variables in the socioeconomic, demographic and institutional domains as predictors of the performance levels attained.

The paper applied a two-stage approach of the technique for order preference by similarity to the ideal solution (TOPSIS) in public hospitals in 92 Rio de Janeiro municipalities, covering the 2008–2013 period. First, TOPSIS is used to estimate the relative performance of hospitals in each municipality. Next, TOPSIS results are combined with neural networks in an effort to originate a performance model with predictive ability. Data refer to hospitals’ outpatient and inpatient services, based on frequent indicators adopted by the healthcare literature.

Despite a slight performance increase over the period, substantial room for improvement is observed. The most important performance predictors were related to the demographic and socioeconomic status (area in square feet and GDP per capita) and to the juridical nature and type of ownership of the healthcare facilities (number of federal and private hospitals).

The results provide managerial insights regarding the performance of public hospitals and opportunities for better resource allocation in the healthcare sector. The paper also considers the impact of external socioeconomic, demographic and institutional factors on hospitals’ performance, indicating the importance of integrative public health policies.

This study displays an innovative context for applying the two-stage TOPSIS technique, with similar efforts not having been identified in the healthcare literature.

Nanoparticles have been studied as additives to lubrication oils for reducing friction and wear. The purpose of this paper is to investigate the effect of nanofluid on engine oil and friction reduction in a real engine.

The nanoparticles were prepared using a high‐temperature arc in a vacuum chamber to vaporize the Ti metal, and then condensed into a dispersant to form the TiO₂ nanofluid, which was used as lubricant additive. Experiments were performed in both real engine running and test rig.

It was found that the engine oil with nanofluid additive with an ethylene glycol dispersant of nanoparticles, had gelled after 10‐h of engine running. The problem of oil gelation (jelly‐like) was solved by replacing the dispersant with paraffin oil. The engine oil with TiO₂ nanoparticle additive exhibited lower friction force as compared to the original oil. The experiment showed that a smaller particle size exhibits better friction reduction with particle size ranging from 59 to 220 nm.

The paper is restricted to findings based on the dispersed nanoparticles in fluid as additive for engine lubrication oil.

The test results are useful for the application of nanofluid additive for engine oil.

Most previous researches in this field were executed on tribotester, rather than the actual engine. This paper describes experimental methods and equipment designed to investigate the application of TiO₂ nanofluid as lubricant additive in internal combustion engine.

The concept of social media crisis has been consequently replaced by the term “paracrisis”. However, the economic implications of the paracrises have not been thoroughly researched by now. The purpose of this paper is to examine the potential influence of paracrisis on companies’ stock price values.

Secondary data analysis has been conducted to identify paracrises for the publicly listed companies and verify that there were no other market events that could affect the stock price during the observed period. Quantitative data analysis has been conducted using the event study, observing stock price values before and during the paracrisis, and the relationship between stock price oscillations and S&P 500 trends was tested.

There were no significant differences in stock price values before and during the paracrisis. Additionally, a strong correlation between S&P 500 and stock price trends has been found. Findings indicate that paracrises do not significantly impact the stock price behaviour and they should be considered as an irrelevant market event from the stock price point of view.

This study is the first research that examines the stock price paracrisis interdependence.

The objective of this study is to investigate the factors of two sub-processes – knowledge donating and knowledge collecting – of knowledge sharing in Hong Kong higher education context. This study examines the individual factors, organizational factors and technology factor of knowledge sharing. Individual factors include enjoyment in helping others and knowledge self-efficacy while organizational factors refer to the top management support, organizational rewards and organizational culture. The use of technology system is proposed to be the technology factor.

Based on the literature review, this study develops a structural model representing the impact of six latent variables on knowledge donating and knowledge collecting processes Data from a questionnaire survey of 166 respondents from academics from Hong Kong higher education sector was used to analyze the model. PLS-SEM was adopted in this study.

The result of the data analysis suggests enjoyment in helping others has a positive impact on both knowledge donating and knowledge collecting. For organizational factors, a trust and collaborative culture enhance both the sub-processes. The technology factor only contributes to the knowledge donating process. Several practical implications are provided to high education leaders, for instance, by establishing a trust and collaborative environment, academics are more eager to donate and collect knowledge.

This paper provides insights for researchers to further understand how individual, organizational and technology factors affect two sub-processes of knowledge sharing. On the practical side, this study validated several critical factors to successful knowledge donation and knowledge collection.

Country of origin has profound effects on consumer behavior; yet few studies have examined an antecedent of these effects: why some countries enjoy a positive image while others suffer a negative one. Developing an institutional theory of country image, the authors argue that weak legal institutions at the country level increase firm opportunistic behavior that expropriates consumers and decrease the product quality of local brands, thus decreasing the country’s image regarding its products and brands.

This study measures country image for products and brands using the number of valuable brands (i.e. brands included in the top 500 brands from 2008 to 2016) in a particular home country. Data concerning the rule of law in each country come from the World Bank, and data on the efficiency of countries’ judicial systems comes from Djankov et al. (2007). We also collect patent data from the US Patent and Trade Office, national culture from Hofstede Insights and GDP and GDP per capita from the World Bank as control variables. Panel Poisson regression, Tobit regression and truncated regression are used in the analyses.

Supporting the institutional theory of country image, both the rule of law and efficiency of the judicial systems show positive and significant effects on country image, even when economy size (GDP), degree of economic development (GDP per capita), level of technology and skill (patents) and culture are controlled.

To improve their country’s image and the brand value of local firms, policymakers should strive to strengthen legal institutions aimed at punishing firm opportunistic behavior in their countries.

Previous research on the country-of-origin effect has not yet appreciated the role of legal institutions in developing the construct of country image.
