Drawing on an evolutionary perspective, prior studies have revealed that conspicuous consumption by men has signaling functions (i.e. signaling the consumer’s positive mate qualities such as status and ability to acquire resources) for mate attraction. However, it is unclear whether conspicuous consumption of luxury products by women has a function in mate attraction. The purpose of this paper is to investigate the effect of mate attraction goal on women’s interest in conspicuous consumption and the possible mediating effect of the attractiveness enhancement need in this effect.

A survey and two experimental studies were conducted in which 354 Chinese female undergraduates participated. In the survey, the respondents’ desire to have a romantic partner was measured; in the two experiments, the participants’ mate attraction goals were primed. The authors followed the literature to measure dependent variables (i.e. consumption measures), but the specific consumption items were adapted to meet the purpose of the current research. The authors analyzed the data from the three studies through analysis of variance, regression analysis and bootstrapping.

Young women with a strong (vs weak) desire for a romantic partner reported a high level of attractiveness enhancement needs, thereby indicating a higher willingness to pay (WTP ) for conspicuous items that can enhance their attractiveness (Studies 1 and 3). Furthermore, activating young women’s mate attraction goal can also increase their WTP for conspicuous items (Studies 2 and 3) and attractiveness enhancement items (Study 3) but not inconspicuous luxury product (e.g. underclothes) (Study 3). These findings suggested that young women consider conspicuous consumption of certain products as a means of enhancing attractiveness to acquire a desired mate.

This research identifies a novel function of conspicuous consumption: young women, especially those who do not have a romantic partner, may use conspicuous consumption of certain products to satisfy their attractiveness enhancement needs and, ultimately, to attract an ideal mate.

Every society has unique factors that contribute to the selection of marriage partner among young adults. These factors have been found to equally determine marital satisfaction and marital stability. This study focuses on married couples in Nigeria and factors that determined how they transcended from their dating period to marriage.

A total of 19 married couples participated in this study, which involved the use of focus group discussions to elicit data from them. Snowball sampling technique was used to obtain respondents who had similar characteristics.

The respondents were aged between 38 and 50 years, had courted for at least 7 years before marriage, and marriage was not less than 10 years. Data was analyzed using content analysis. Themes bordered on factors determining choice of partner, how they met, length of their dating, and courtship periods. Physical attractiveness, as a determining factor, was clearly evident among participants. Participants agreed that communication was vital to marriage stability.

The study brought to light that in spite of strong traditional values, Nigerians displayed romantic characteristics similar to Western societies such as the United States and the United Kingdom. The study was limited because of the method adopted for selecting participants. Also, some variables such as ethnic background and educational background were not included in the study. The study recommends future studies which may be longitudinal, involving couples’ personality traits, families of origin, and so on, in order to yield more salient issues.

A novel sexual adaptive genetic algorithm (AGA) based on Baldwin effect for global optimization is proposed to overcome the shortcomings of traditional GAs, such as premature convergence, stochastic roaming, and poor capabilities in local exploring. This paper seeks to discuss the issues.

The proposed algorithm simulates sexual reproduction and adopts an effective gender determination method to divide the population into two subgroups of different genders. Based on the competition, cooperation, and innate differences between two gender subgroups, the proposed algorithm adjusts adaptively sexual genetic operators. Furthermore, inspired by the acquired reinforcement learning theory based on Baldwin effect, the proposed algorithm guides individuals to forward or reverse learning and enables the transmission of fitness information between parents and offspring to adapt individuals' acquired fitness.

Global convergence of the proposed algorithm is proved in detail. Numerical simulations are conducted for a set of benchmark functions with different dimensional decision variables. The performance of the proposed algorithm is compared with that of the other evolutionary algorithms published recently. The results indicate that the proposed algorithm can find optimal or closer‐to‐optimal solutions, and is more competitive than the compared algorithms.

The proposed algorithm introduces, integrates and simulates correctly and adequately, for the first time, the mechanisms of sexual reproduction, Baldwin effect and adaptation to GAs by referring to the latest research results of modern biology and evolution theory.

The recent wave of immigration to North American society from new source countries challenges old theories of acculturation that were based on European immigration streams that assumed that ethnic retention was generationally conditioned. For Caucasian immigrants, it was assumed that assimilation was linear and that by the third generation, all traces of ethnic origin would be absent, save for a nostalgic interest in quaint and ephemeral aspects of an ethnic past labeled symbolic ethnicity (Child, 1943; Gans, 1979; Rumbaut, 1997; Waters, 1990). Since 1965 in the United States, and 1967 in Canada, changes in immigration policy suggest that alternative assimilation patterns may exist. Whereas previous immigration policy had discouraged non-Caucasian immigration, the new policy brought with it large-scale immigration from Asia in particular which introduced a different element of race into assimilation expectations. For these new immigrants, race continues to be a marker whereby prejudice, stereotyping, and discrimination produce assumptions of “foreignness” regardless of generational status (Neckerman, Carter & Lee, 1999; Tuan, 1999).

Purpose – The purpose of this paper is to verify whether an evolutionary model outperforms logistic regression in determining the institutional placement decisions made by a London social service department panel. Design/methodology/approach – Genetic chromodynamics models an algorithm within the Michigan evolutionary classifier. Hence multiple classification rules evolve simultaneously. The dataset as described by Xie et al. is used. Two‐thirds of randomly selected cases are for training and one third for testing. Indicator weights are set between 0 and 1. Findings – Of 275 placements, 40 per cent represent residential homes, 48 per cent nursing homes, 12 per cent nursing long‐stay and two hospital long‐stay. In ten runs, 89.18 per cent were correctly placed (range 81.6 to 97.7 per cent); 5.07 per cent wrongly placed (range 1.2 to 8.0 per cent) and 5.75 per cent unplaced (range 0.0 to 11.5 per cent). Changing the 0.99 weights to 0.90 and 0.80 placed 87.6 and 87.9 per cent correctly. Research limitations/implications – Data came from written records. Errors in transcription and placement could not be checked. Other facts, or the weights, may be influencing placement decisions. Practical implications – Xie et al. matched 78 per cent of 195 placements. The evolutionary model outperformed logistic regression both in placements evaluated (275/195) and accuracy (89/78 per cent). Therefore, it could be used as a first line management information tool, revealing whether guidelines are followed. Originality/value – The authors have developed and tested a computational model, which could be used to evaluate institutional placement decisions in the UK “market”. Further development and exploitation would facilitate greater understanding of the needs old people and the resources necessary for their appropriate management.

The growing cost and difficulty related to “finding someone” suggests that the role of service organisations in explicitly supporting and designing opportunities for love between customers merits further attention. This study employs a multidisciplinary approach of both services marketing and the economics of mate choice to understand how service organisations can exercise the third place effect and facilitate human mate choice (love) opportunities for consumers in extended service encounters.

Three qualitative co-design workshops were conducted with actors (students, casual and professional staff) from the Australian university ecosystem (n = 36) to identify consumer expectations related to mate selection in third place service contexts. A quantitative online survey of (n = 1207) current Australian university students was used to rank the importance of core and enhancing service elements.

The authors find that love holds a status in the minds of some consumers as an implicitly expected by-product of participation within the core service consumption experience in third places. For service providers to facilitate mate choice opportunities in third places, the results suggest that the design of the connective mechanism(s) should maximise opportunities for informal consumer-to-consumer interaction to allow prospective partners to ascertain compatibility. Further, consumers expect the organisational facilitation of engagement in order to clarify expected etiquette and support goal congruence. In the tertiary education marketplace for love, there is an increased preference for interpersonal engagement by those studying on campus (compared to externally), and a positive relationship between duration of enrolment and increased priority for mate choice service provision.

This research makes a novel theoretical and empirical contribution by being the first exploration of the economics of third place love in the tertiary education sector, also being a research primer for the field of services marketing to consider service design in third places to support mate choice.

The purpose of this study was to investigate assortative mating processes inside Internet-dating-service settings. Unattached consumers traditionally sought to satisfy their need for love through conventional search processes, including old-fashioned match-making. That was then, this is now; dozens of internet-mediated dating websites promising romantic-love-matches currently operate internationally. These dating services cultivate dating-exchanges by offering new-fashioned match-making processes. Despite these trends, theoretical and practical questions related to how and why dating services marketers might induce superior romantic exchanges between customers by managing assortative mating processes remain unanswered until now.

A survey-based approach was used to test hypotheses. Pretests were conducted to develop reliable measures of assortative mating propensity. Seven subconstructs of assortative mating were identified by analyzing data from a representative sample. The measurement model was validated before hypotheses testing. The focal assortative mating construct was measured formatively; assortative mating subdimensions functioned as indicators. The model was tested by structural equation modeling.

Assortative mating processes facilitated superior preference-selection outcomes for individuals seeking consumer-to-consumer romantic relationships inside internet-mediated service settings. Insights were generated about how and why assortative mating processes exercised positive effects on consumers’ attitudes toward online dating and about how dating services marketers might leverage assortative mating tendencies to benefit consumers.

A novel concept was introduced to the services marketing literature, as were several theoretical implications. The study simultaneously measured consumers’ propensities to engage in assortative mating and captured the effects of various physical/behavioral consumer characteristics. This study develops new and practical insights about how dating service marketers could manage the effects of assortative mating processes.

This chapter analyzes characteristics and changing patterns of marriage formation in Vietnam over the past 50 years, from various aspects including the motives underpinning marriage decision-making, the process of mate acquaintance, the criteria for mate selection, and marriage decision-making rights. The chapter is based on a review of data derived from the Vietnam Family Survey 2006 (MOCST et al., 2008) and the Vietnam Marriage Survey 2017 (Minh, 2021). It shows that the pattern of marriage formation in Vietnam has changed significantly in the past decades under the influence of various socio-economic and legal factors. Marriage is increasingly associated with the value of personal happiness. People today have many more opportunities to meet and get to know each other before marriage than older generations in the past. Adolescents spend more time getting to know their future spouse and have more options when choosing future partners before marriage. Marriage based on a partner’s individual qualities is preferred, gradually replacing mate selection based on family background. Parents’ power over their children’s marriage has decreased, while young people are becoming more and more independent in making decisions about their lives. In other words, today, it is the interests of the people involved in the marriage that matters, not only the interests of the family and kinship that determines marriages. However, despite these new marriage formation patterns, the belief that children’s marriage is an important affair for the whole family is still maintained. The general pattern is that there is a mix of personal factors and family circumstances regarding the marriage choices.
