ABSTRACTRotavirus is the leading cause of infantile diarrhea in developing countries, where it causes a high number of deaths among infants. Two vaccines are available, being highly effective in developed countries although markedly less efficient in developing countries. As a complementary treatment to the vaccines, aLactobacillusstrain producing an anti-rotavirus antibody fragment in the gastrointestinal tract could potentially be used. In order to develop such an alternative therapy, the effectiveness ofLactobacillus rhamnosusGG to produce and display a VHH antibody fragment (referred to as anti-rotavirus protein 1 [ARP1]) on the surface was investigated.L. rhamnosusGG is one of the best-characterized probiotic bacteria and has intrinsic antirotavirus activity. Among fourL. rhamnosusGG strains [GG (CMC), GG (ATCC 53103), GG (NCC 3003), and GG (UT)] originating from different sources, only GG (UT) was able to display ARP1 on the bacterial surface. The genomic analysis of strain GG (UT) showed that the geneswelEandwelFof the EPS cluster are inactivated, which causes a defect in exopolysaccharide (EPS) production, allowing efficient display of ARP1 on its surface. Finally, GG (UT) seemed to confer a level of protection against rotavirus-induced diarrhea similar to that of wild-type GG (NCC 3003) in a mouse pup model, indicating that the EPS may not be involved in the intrinsic antirotavirus activity. Most important, GG (EM233), a derivative of GG (UT) producing ARP1, was significantly more protective than the control strainL. caseiBL23.

PurposeBoth foreign and local companies frequently name their brands in foreign language on the market of developing countries, and some of them choose to disclose the brands' country of origin to consumers. The purpose of this research is to investigate the joint effects between the practices of disclosing the actual country of origin of the brands and the language of the brand names on consumers' purchase intention for foreign brands and local brands in developing countries.Design/methodology/approachThe proposed hypotheses were tested in two studies, namely an experiment and a field experimental survey, with stimuli from two product categories.FindingsThe results of the two empirical studies with Chinese participants consistently demonstrate that revealing the actual country of origin of the brands undermines consumers' purchase intention for local brands that use foreign brand names, but does not impact consumers' purchase intention for foreign brands that use local brand names.Originality/valueThis research first investigates the effects of adapting the brand names into local language of developing countries for brands from developed countries on consumers' purchase intention, which provides new insight into the literature on foreign branding and country of origin effects as well as practical implications for brand managers.

Purpose This study aims to comparatively discuss the effect of lean manufacturing (LM) implementation in the manufacturing sectors of developing and developed countries. Design/methodology/approach An in-depth literature review focused on previous research published between 2015 and March 2020. The papers published by the databases such as Google Scholar, Scopus, ProQuest and Web of Science were used in the study. A total of 63 studies that focused on LM application in manufacturing industries in developing and developed countries were used in the research. Findings It was observed that LM improves operational performance for manufacturing organizations in developing and developed countries. Small and medium-sized enterprises in both developed and developing countries have difficulties transforming their organizations into lean organizations compared to large enterprises. Furthermore, the review also found that there seems to have been no paper had reported the negative impact of implementing LM in manufacturing industries in developing and developed countries from 2015 to March 2020. Research limitations/implications The study used research papers written between January 2015 and March 2020 and only considered manufacturing organizations from developed and developing nations. Practical implications The study provides more insight into LM implementation in developing and developed countries. It gives the LM practices and the implications of applying these practices in manufacturing organizations for developing and developed countries. Originality/value A preliminary review of papers indicated that this seems to be the first paper that comparatively studies how LM implementation has affected manufacturing organizations in developed and developing countries. The study also assessed the LM practices commonly used by the manufacturing industries in developing and developed countries.

Purpose Hospital information system (HIS) can be examined as a vital factor for developing the quality of health care and cost managing. There exists abundant literature on HISs, but implementation-based literature of HIS is rare, typically about progressive countries. However, a study that can comprehensively review published articles is scarce. Therefore, this paper aims to examine the systematic and comprehensive study of HIS in developed countries. Together, the benefits and harms relevant to HIS’s different mechanisms have been considered, and the fundamental challenges of them are addressed to design more efficient HIS in the future. Design/methodology/approach HIS has been used globally for numerous years and is now being used in a wide area. HIS is broadly used in clinical settings. Information technology (IT) and information system have been suggested as a required piece to solve the health-care-related issues. Hence, to improve HIS’s ability, this paper conducted a review method concentratating on research related to HIS until 2019. A total of 21 papers were recognized and examined as principal research for the summary. Findings The authors found that HIS can help in reduction of medical mistakes, enhancement doctors’ performance and increase in the quality of the care provided. HIS management can be used to provide better health-care services. Therefore, HIS must be sensible and use clear structures. The authors conclude that, generally, with an increase in awareness, acceptability and the need for HIS worldwide, there will be more strategies and approaches available. Research limitations/implications First, this paper provides an outline of the status of HIS. Second, it identifies some distinct research gaps that could be worth studying. Some flawless work may be removed because of applying some filters to select the original articles. Surveying all the papers on the topic of HIS is impossible, too. Practical implications Design and sustainability of HIS is still a big issue for most developing countries, despite its wide usage in the developed countries. The technology is changing rapidly, so the field should be reviewed regularly. This paper suggests a suitable framework that will guide HIS in the local conditions of developing countries. Social implications The government will be assisted by the suggested solving ways in its performance and design of electronic health-care projects. Originality/value The study brings the viewpoints on the state of HIS mechanisms in developing countries. The paper’s results can offer visions into future research requirements. By providing comparative information and analyzing the current growths in this area, this study will support researchers and professionals to understand the progress in HIS mechanisms better.

Purpose The purpose of this paper is to review studies focusing on the magnitude of money laundering and their effects on a country’s economy. The relevant concepts are identified on the basis of discussions in the literature by prominent scholars and policy makers. There are three main objectives in this review: first, to discuss the effects of money laundering on a country’s macro-economy; second, to seek measurements from other scholars; and finally, to seek previous findings about the magnitude and the flows of money laundering. Design/methodology/approach In the first part, this paper outlines the effects of money laundering on macroeconomic conditions of a country, and then the second part reviews the literature that measures the magnitude of money laundering from an economic perspective. Findings Money laundering affects a country’s economy by increasing shadow economy and criminal activities, illicit flows and impeding tax collection. To minimise these negative effects, it is necessary to quantify the magnitude of money laundering relative to economic conditions to identify the most vulnerable aspects of money laundering in a country. Two approaches are used in this study: the first is the capital flight approach, as money laundering will cause flows of money between countries; the second is the economic approach for measuring money laundering through economic variables (e.g. tax revenue, underground economy and income generated by criminals) separately from tax evasion. Originality/value The paper offers new insights for the measurement of money laundering, especially for developing countries. Most methods in quantifying money laundering have focused on developed countries, which are less applicable to developing countries.

Purpose Multi-channel business operations are standard practice in most business contexts today. The popularity of multi-channel adoption among developing countries is growing fast. In Bangladesh, the retailers who adopted multi-channel retailing have been getting a very good response from the consumers. This study aims to understand the factors that influence manufacturers’ decisions to adopt multiple channels in Bangladesh. The authors applied an extended technology acceptance model with three variables: business innovation, business competition and consumer satisfaction. Design/methodology/approach Partial least squares-structural equation modeling was applied to test the data collected from 157 companies and relevant hypotheses. Findings The study findings show that Bangladeshi manufacturers are positive about, and expect benefits from, applying the new channel. The study also revealed that customer satisfaction considerably affects multi-channel adoption in Bangladesh. Similarly, business innovation and business competition play a significant role in introducing multiple business channels. Research limitations/implications This research was conducted in Bangladesh, and data are collected from Dhaka and Chittagong that may limit the generalizability of findings. Practical implications The research goal was to understand a manufacturer’s perception to adopt multi-channel in business. The proposed research model was able to address the major factors that drive a manufacturer to introduce multiple business channels, especially in Bangladesh. Originality/value Many research and case studies have been done the past couple of decades, but most of them are consumer oriented. Little research has been done to investigate a manufacturer’s point of view adapting innovation in business. Though some research articles are available online, most of them from developed countries. So, the study’s goal was to study developing countries scenario; thus, the authors choose Bangladesh.

Purpose This study aims to investigate the trends in existing studies in the field of ethnic entrepreneurship in the context of growing markets in terms of definitions, theories, themes, methodologies and settings. Design/methodology/approach This study used bibliometric analysis and used Publish or Perish software with Google Scholar as the database. A total of 183 articles published in 122 journals from 1988 to 2018 were selected. This study used systematic data to reveal trends in growing markets and qualitative inductive analysis to define relevant themes within the topic. Findings The results show that ethnic entrepreneurship is defined as involving immigrants from developing countries. From a theoretical point of view, socio-cultural theories, socio-economic theories and combinations of both have been used to explain the phenomenon. Six research themes have been developed indicating potential explorative and exploitative research themes. This study identified the dominance of the qualitative approach in ethnic entrepreneurship research and found that the typical research subjects are Asian immigrants, especially Chinese, in developed countries. The articles reviewed were mainly conducted in developed countries (68.85%) and a lesser portion in developing countries (13.66%), particularly Asian countries. Practical implications This study provides future directions for research on ethnic entrepreneurship, such as gender studies of ethnic entrepreneurs and factors affecting the opening of new businesses in new locations. Originality/value This study reveals trends in the ethnic entrepreneurship field based on the country in which the study was conducted, the definition of ethnic entrepreneurship, the theories, the research themes, the methodologies, the research setting and the ethnicity studied. It also used the framework of input–process–output to establish a generic road map of the ethnic entrepreneurship research area.

Purpose This study aims to extract information and analyze the antecedents of Muslims following pilgrimage tours. Data from the Central Bureau of Statistics Indonesia shows that 87.18 per cent of the total population of Indonesia are Muslims. In addition to running the ruling of Islam and the pillars of Faith, Muslims also maintain the religious tourism. The form of religious tourism which is widely followed by the Muslims of Indonesia is to follow a pilgrimage to the tomb of the wali (Guardian), both wali limo and wali songo. Design/methodology/approach This study used a qualitative approach. Data collection was done using in-depth interviews of Muslims in Indonesia who had already attended pilgrimages to wali limo and/or wali songo. Findings The tourists are satisfied and have an intention to revisit the destination, and the interest of the community to follow religious tours is very large, as well as the opportunities to do business in this sector are still wide open. Various motives and benefits of following religious tours, as well as suggestions for improvements for religious tourism destination managers, as well as advice for the government were uncovered. Thus, the results of this study are expected to provide a theoretical contribution related to marketing management in religious tourism and a practical contribution for the managers of religious tourism. Research limitations/implications Further research can be done with a quantitative approach, as well as comparative studies between pilgrimages in Indonesia (developing countries) and pilgrimages in other developing countries or in developed countries can also be conducted. Practical implications For marketing practitioners, the results of this study can be used as a consideration to continue to improve services in the field of religious tourism in the country, given the potential for development is very large. Social implications There is a contribution from this study to the development of marketing science, particularly related to marketing management on religious tourism services. Originality/value This study offers new insight regarding factors influencing Muslims pilgrimage tourism in Indonesia.

PurposeThe paper attempts to empirically examine the difference in the foreign direct investment (FDI) – private investment relationship between developed and developing countries over the period 2000–2013.Design/methodology/approachThe paper uses the two-step GMM Arellano-Bond estimators (both system and difference) for a group of 25 developed countries and a group of 72 developing ones. Then, the PMG estimator is employed to check the robustness of estimates.FindingsFirst, there is a clear difference in the FDI – private investment relationship between developed countries and developing ones. Second, governance environment, economic growth and trade openness stimulate private investment. Third, the effect of tax revenue on private investment in developed countries is completely opposite to that in developing ones.Originality/valueThe paper is the first to provide empirical evidence to confirm the dependence of FDI – private investment relationship on governance environment. In fact, contrary to the view (arguments) in Morrissey and Udomkerdmongkol (2012), the paper indicates that FDI crowds out private investment in developed countries (good governance environment), but crowds in developing countries (poor governance environment).

Purpose This paper aims to explore international talent mobility and identify its negative/positive factors. Design/methodology/approach Bibliometric data from Scopus are explicated to model the mobility network and providing a more comprehensive posture. In addition, by using indicators of complex network, significant features of international talent mobility are described quantitatively. After that, by introducing a kind of improved gravity model with multiple linear regression, the authors identify factors to explain international talent mobility flows. Findings With the analysis of international talent mobility in complex network, the overall network is not balanced. A small part of developed countries and developing countries with good emergency attract and drain a lot of talents and talents usually moving between these countries, the amount of talents leaving or entering into other countries is very limited. Furthermore, according to multiple linear regression, it is found that the share of migrants in population is the major negative factor for international talent mobility, and the factors of destination countries is more significant than original countries. Originality/value The result of this paper may support further research studies and political suggestions for cultivating, attracting and retaining scientific and technological talents in the world.

Purpose The increasing demand for public infrastructure has caused a rise in the global adoption of the public–private partnership (PPP) concept. However, over the past years, most of the developing countries have failed to attract more private investments as realised in the developed countries. This paper aims to investigate the critical factors that attract private investments in the PPP markets of developing countries. Design/methodology/approach An empirical questionnaire survey was conducted with targeted international PPP experts from the academic and industrial sectors. The inter-rater agreement analysis, mean score ranking and Mann–Whitney U test were used to analyse the survey responses. Findings Results indicate that the three most critical factors are political support and acceptability for PPPs, government positive attitude towards private sector investments and political stability. On the other hand, factors including government guarantees, competent PPP unit and tax rebate on imported equipment are of low importance. The Mann–Whitney U test reveals that experts from the academic and industrial sectors view the importance of three factors differently: adequate public sector experience in PPP, government providing guarantees and government providing tax rebate on imported equipment. Originality/value The research outputs contribute to the existing but limited knowledge on PPP practices in developing countries by providing empirical evidence and cross-cultural perceptions on the conditions that are critical to the expansion of PPP markets in developing countries. It is therefore expected that governments and policymakers seeking to adopt the PPP concept would take into consideration the results and implications to enhance PPP growth.
