“…At last 24 articles were included (see selection flowchart in Figure 1). The studies (16,19,20,28,(39)(40)(41)(42)(43)(44)(45)(46)(47)(48)(49)(50)(51)(52)(53)(54)(55)(56)(57)(58) included for each of the three groups are shown in Table 1.

“…We also conducted a subdivision comparison between female and male in the age 16-35 (16,19,20,40,45,47,49,52) . However, compared to the age 18-50, the effect size was relatively small (Cohen's d=0.36, 95% CI: 0.18 to 0.54), though a significant difference (Z = 3.87, p=0.0001) was found that female outperformed male in odor identification.…”

“…Examination of electrophysiological measures consistently show different odor event-related potentials between females and males, with a larger amplitude and shorter latency of the P2 component in women compared with those in men (11)(12)(13)(14) . At the behavioral level, most studies have demonstrated that women outperform men in olfactory function, especially in odor identification (15,16) , but there are also numerous studies that did not find an effect of gender on odor identification (17)(18)(19)(20) . Doty et al (21) reported that a gender effect existed across all age categories, whereas many studies did not find gender differences present at different life stages.…”

Background: Although conflicting findings abound, gender-related differences in olfactory identification have received continuous attention. To our best knowledge, no systematic and quantitative research has examined gender differences in olfaction identification at various stages of life. The present study aimed to find out if there is gender difference in human olfaction identification in different life stages. Methodology: Studies cited in the PubMed database were searched from its inception to August 2017 using the terms "olfact*" or "smell" and "gender" or "sex". The effect size of each comparison was calculated. 24 studies were included in this meta-analysis. Results: In this meta-analysis, we used Cohen's d to determine the effects sizes for the comparisons between women versus men among different groups. Its value was 0.18 (95% CI:-0.13 to 0.49) in Group A (age<18years), 0.62 (95% CI: 0.43 to 0.81) in Group B (age 18-50years), and 0.33 (95% CI:-0.01 to 0.66) in Group C. The effect was considered relatively small in Group A (age<18years) and Group C (age>50years), and a medium effect in Group B (age18-50 years). Moreover, a significant difference was only present in Group B (age18-50 years). Summarizing, the gender effect was only present in the group aged 18-50 years, in which women outperformed men significantly in odor identification. Conclusions: This meta-analytic review indicated that the gender differences only exist in young adults (age18-50 years), while absent in juveniles (age<18years) or an aged cohort (age >50years). Females outperformed males in the young adults.

Facilitating mCommerce Growth in Nigeria through mMoney Usage: A Preliminary Analysis

A general belief is that Mobile Money (mMoney) has the catalytic effect of spurring mCommerce growth and driving financial inclusion in developing nations like Nigeria. In Nigeria, mMoney service is certainly a new financial service innovation in the country, and as a result critical issues surrounding its early critical mass adoption, including its perceived usefulness, remain largely opaque. In this paper, our aim was to explore factors influencing perceived usefulness of mMoney by using the extended technology acceptance model (TAM) as the theoretical underpinning of our work. This work is based on a usable sample of 127 respondents from two major cities in Nigeria. Overall, the study's results indicate that perceived regulator assurance, service affordability, convenience, proximity to the nearest bank branch, and worry over ease of use are significant predictors of mMoney perceived usefulness. The work helps shed new insights about the significant factors that are closely related to the consumer's perception of the relevance of mMoney services (to his/her financial needs). In sum, the study is an initial step to addressing the issue of perceived usefulness of mMoney service, including its pivotal importance to laying a solid foundation for mCommerce growth in Nigeria and similar sub-Saharan African (SSA) countries.

“…It was possible that MSM males perform better in olfactory tasks than heterosexual, thus the observed lack of difference in olfactory sensitivity. The recent literature shows however, that it is gender nonconformity and sex-atypicality rather than sexual orientation (Nováková et al 2013) that influence sexual orientation. However, to further address this issue, the multiple regression analysis was performed.…”

On the relationship between olfactory sensitivity and personality in HIV-seropositive and healthy men

et al. 2018

The aim of this study was to further elucidate the relationship between the olfactory system and psychosocial functioning. Previous studies have shown that olfactory sensitivity is related to traits such as extraversion, agreeableness, and emotionality. In this study, the model of agency and communion as well as additional measures of social activity were used. The possible influence of HIV infection, believed to affect both chemosensory functions and social behaviors, was examined. 103 male participants were analyzed, of whom 45 were infected with HIV. Olfactory sensitivity was significantly related to the level of communion (p = .01), trait defined as interpersonal warmth, devotion to others, and morality. The effect was independent of the presence of HIV. Eagerness to engage in social activities, a construct indicating how actively one takes part in social life, was positively associated with olfactory sensitivity only in HIV+ individuals (p = .003). This result may imply that active participation in social life can buffer olfactory impairments in HIV patients.
