The support of host country nationals (HCNs) is a key determinant of expatriate adjustment and performance. The purpose of this paper is to explore underlying motivations for their support to expatriates. Previous research has shown that HCNs with pro-social motivation are more likely to help expatriates. Drawing upon motivated information processing in groups (MIP-G) theory, the authors test whether epistemic motivation moderates the observed relationship between pro-social motivation and HCNs’ support toward expatriates.

The authors ran two correlational studies (N = 267) in the USA (Study 1) and South Korea (Study 2). Across two studies, epistemic motivation and social motivation were measured using their multiple proxies validated in previous research. The authors also measured HCNs’ willingness to offer role information and social support to a hypothetical expatriate worker.

Results lend support to our hypotheses that pro-social HCNs are more willing than pro-self HCNs to provide role information and social support to the expatriates, but this occurs only when they have high rather than low epistemic motivation.

The current paper contributes the literature on HCNs helping expatriates by qualifying the prior results that a pro-social motivation (e.g. agreeableness and collectivism) increases the willingness of HCNs to help expatriates. As hypothesized, this study found that that case is only true when HCNs have high, rather than low, epistemic motivation. Also, previous research on MIP-G theory has mainly focused on the performance of small groups (e.g. negotiation, creativity and decision-making). To the best of the authors’ knowledge, this research is the first attempt to test MIP-G theory in the context of HCNs helping expatriates.

The support of host country nationals (HCNs) is critical for expatriate adjustment and performance. Drawing from social identity theory and self-categorization theory, this study investigates the antecedents of HCNs' support toward expatriates in Central/South America, focusing on cultural similarities and expatriate race.

We conducted a quasi-experimental study to understand the antecedents that promote the willingness of HCNs to offer required support to expatriates. Data were gathered from 117 Latin American participants, who were asked to respond to questions about their perceptions of expatriates from the USA and their willingness to offer support to those expatriates.

Overall, our findings suggest that HCNs are likely to provide support to expatriates when they perceive the expatriates as similar in terms of culture and race. Specifically, African Americans received more positive attitudes and support than White Americans in South/Central America. The effect of cultural similarity on HCN willingness to support expatriates was mediated by perceived trustworthiness.

The present study extends the research on HCN support to expatriates, to Central/South America, an important region that has been under-studied in the expatriate–HCN context. Another novel feature of our study is that we investigate the role of expatriate race and cultural similarity and illuminate the underlying mechanism of the relationship between expatriate race and HCN support.

The purpose of this paper is to review the nutritional composition, phytochemicals and bioactive compounds of black rice such as flavonoids, phenolic compounds and their health benefits. Black rice has also been used in medicine and for curing diabetes, obesity, cardiovascular diseases and cancer. Green technologies such as microwave-assisted extraction, supercritical fluid extraction and pulse electric field assisted extraction are very useful for the extraction of bioactive compounds as these reduce the use of energy and are environmental friendly. Black rice in different forms can be incorporated in various food products such as bakery, dairy and meat products.

Information and data were collected from different sources such as Google Scholar, Research Gate, online journals available at Banaras Hindu University library, Web of Science and Scopus. A database of more than 80 scientific sources from different sources was made as per the headings and subheadings of the paper.

Black rice is a type of rice species (Oryza sativa L.) and very good source of various nutrients and one of the nutritious varieties of rice. It is a good reservoir of essential amino acids such as lysine, tryptophan, minerals including iron, calcium, phosphorus, zinc and selenium; vitamins such as vitamin B1, vitamin B2 and folic acid. Various recent methods of extraction of bioactive compounds from black rice are suggested.

Researchers and scientists have considered black rice as a “Super Food” because of its nutritional profile. Black rice has antioxidant activity, anti-inflammatory activity, anticancer activity, antihyperlipidemia and antihyperglycemia and anti-allergic activity. There is a need to create awareness among the consumers about its nutritional profile and therapeutic properties.
