HOW FEMALE DIFFER IN DECISION MAKING FOR PERSONAL INVESTMENT STRATEGY

This study investigates Lithuanian females’ personal investment peculiarities in line with Australia’s case analysis and application as a good practice method. Based on many publicly available research females tend to have less knowledge about finances in general and particularly investment processes; hence, it leads to their lack of interest into investing and the possibility of poor money management. This issue might be solved by investigating why it appears first and adopting the practical example from countries with developed investment market. In the case of comparison of personal investment strategies among Lithuanian and Australian females the two sets of questionnaires have been used to collect the data for further analysis. The main findings revealed by the survey were, that women in Australia had a higher financial literacy level, invested more often, and chose broader variety of investment instruments compared to Lithuanian females. Moreover, the significant discovery of the article disclosed that Lithuanian females chose not to invest due to the lack of additional funds and the shortage of financial knowledge. The main limitation occurred during the research was the lack of the available data on personal investment topic in Lithuania’s official statistic sources such as The Lithuanian Department of Statistics. The results of the research contribute towards improving Lithuanian female personal finance and investment areas and could be applied to further studies or used for the education program dedicated to financial literacy among women in Lithuania creation. Furthermore, this article creates an original value to personal finance, investment, and financial literacy areas in Lithuania by introducing an idea to not only conduct more studies in these fields, but also to use comparative analysis and good practice method from the countries that demonstrates high achievements in personal finance and gender equality areas. Keywords: personal investment management, female investment, financial literacy, investor’s profile, investing, investment options, investment strategies.

Sex Matters: Effects of Sex and Mating in the Presence and Absence of a Protective Microbe

In most animals, female investment in offspring production is greater than for males. Lifetime reproductive success (LRS) is predicted to be optimized in females through extended lifespans to maximize reproductive events by increased investment in immunity. Males, however, maximize lifetime reproductive success by obtaining as many matings as possible. In populations consisting of mainly hermaphrodites, optimization of reproductive success may be primarily influenced by gamete and resource availability. Microbe-mediated protection (MMP) is known to affect both immunity and reproduction, but whether sex influences the response to MMP remains to be explored. Here, we investigated the sex-specific differences in survival, behavior, and timing of offspring production between feminized hermaphrodite (female) and male Caenorhabditis elegans following pathogenic infection with Staphylococcus aureus with or without MMP by Enterococcus faecalis. Overall, female survival decreased with increased mating. With MMP, females increased investment into offspring production, while males displayed higher behavioral activity. MMP was furthermore able to dampen costs that females experience due to mating with males. These results demonstrate that strategies employed under pathogen infection with and without MMP are sex dependent.

Ecological effects on female bill colour explain plastic sexual dichromatism in a mutually-ornamented bird

Sex differences in ornamentation are common and, in species with conventional sex roles, are generally thought of as stable, due to stronger sexual selection on males. Yet, especially in gregarious species, ornaments can also have non-sexual social functions, raising the possibility that observed sex differences in ornamentation are plastic. For example, females may invest in costly ornamentation more plastically, to protect body and reproductive ability in more adverse ecological conditions. We tested this hypothesis with experimental work on the mutually-ornamented common waxbill (Estrilda astrild), supplementing their diets either with pigmentary (lutein, a carotenoid) or non-pigmentary (vitamin E) antioxidants, or alleviating winter cold temperature. We found that both lutein and vitamin E supplementation increased red bill colour saturation in females, reaching the same mean saturation as males, which supports the hypothesis that female bill colour is more sensitive to environmental or physiological conditions. The effect of vitamin E, a non-pigment antioxidant, suggests that carotenoids were released from their antioxidant functions. Alleviating winter cold did not increase bill colour saturation in either sex, but increased the stability of female bill colour over time, suggesting that female investment in bill colour is sensitive to cold-mediated stress. Together, results show that waxbill bill sexual dichromatism is not stable. Instead, sexual dichromatism can be modulated, and even disappear completely, due to ecology-mediated plastic adjustments in female bill colour.

Male Investment and Male Choice

In this short chapter I revisit the role that male investment might play in the evolution of male mate choice. Simply put, one might expect with more male investment into reproduction, they may be more selective about with whom they mate. If the male investment is larger than the female investment sex roles are expected to flip. This is, however, not common. But even if males almost never invest as much or more than females, in many species they do invest somewhat, or even heavily. Should this lead to choosiness in males? I will provide a few examples where choosiness may be linked to investment in males.

Sex matters: effects of sex and mating in the presence and absence of a protective microbe

In most animals, female investment in offspring production is greater than for males. Lifetime reproductive success (LRS) is predicted to be optimised in females through extended lifespans to maximise reproductive events. Extended lifespan can be achieved through increased investment in immunity. Males, however, maximise lifetime reproductive success by obtaining as many matings as possible. Microbe-mediated protection (MMP) is known to affect both immunity and reproduction, but whether the two sexes respond differently to the provision of MMP remains to be explored. Here, we investigated the sex-specific differences in host life history traits between female and male Caenorhabditis elegans following pathogenic infection with Staphylococcus aureus with or without MMP by Enterococcus faecalis. Overall, female survival decreased with increased mating. With MMP, females increased investment into offspring production, while males displayed higher behavioural activity. These results highlight the different strategies employed by the two sexes under pathogen infection with and without MMP.

Ecological Effects on Female Bill Color Explain Plastic Sexual Dichromatism in A Mutually-Ornamented Bird

Sex differences in ornamentation are common and, in species with conventional sex roles, are generally thought of as fixed, due to stronger sexual selection on males. Yet, especially in gregarious species, ornaments can also have non-sexual social functions, raising the possibility that observed sex differences in ornamentation are not fixed. For example, females may invest in costly ornamentation more plastically, to protect body and reproductive ability in more adverse ecological conditions. We tested this hypothesis with experimental work on the mutually-ornamented common waxbill (Estrilda astrild), supplementing their diets either with pigment (lutein, a carotenoid) or non-pigment (vitamin E) antioxidants, or alleviating winter cold temperature. We found that both lutein and vitamin E supplementation increased red bill colour saturation in females, reaching the same mean saturation as males, which supports the hypothesis that female bill colour is more sensitive to environmental or physiological conditions. The effect of vitamin E, a non-pigment antioxidant, suggests that carotenoids were released from their antioxidant functions. Alleviating winter cold did not increase bill color saturation in either sex, but increased the stability of female bill color over time, suggesting that female investment in bill color is sensitive to cold-mediated stress. Together, results show that waxbill bill sexual dichromatism is not fixed. Instead, sexual dichromatism can be modulated, and even disappear completely, due to ecology-mediated plastic adjustments in female bill color.

Dutch investment advisors’ perceptions towards the MiFID II directive

Purpose The Markets in Financial Instruments Directive (MiFID) II directive was enforced in the EU in January 2018. While EU-member states implemented this directive in their national legislation, investment firms are still enforcing compliance. With the purpose of “investor protection”, the purpose of this study is to investigate the effectiveness of transparency, suitability, warning and information requirements. How do investment advisers view and embrace these MiFID II requirements? Are differences evident within this group of professionals? Design/methodology/approach In total, 267 Dutch investment advisors serving non-professional investors daily completed structured surveys on their opinion of the acceptance and effectiveness of the MiFID II requirements. The findings are compared with existing literature to examine similarities with other legislation. Findings The results demonstrated differences depending on the investment firms’ size and investment advisors’ seniority and gender. Professionals should be critical of new legislation and regulations, as it limits their autonomy. However, female investment advisors and those with up to ten years’ experience are less critical of the effectiveness of the MiFID II requirements, embracing them without discussion. Investment advisors in large investment firms believe that MiFID II contributes to investors’ interests, whereas those in small and medium-sized investment firms often do not share this opinion. For example, respondents considered cost transparency an effective requirement to achieve better investment services and protect investors’ interests. Originality/value The effectiveness and applicability of legislation are often viewed from a legal perspective, and enforcement is essential. However, this study explores legislation from the perspective of professionals under supervision.

Biparental negotiation or larval begging? Determinant of male provisioning in a burying beetle (Nicrophorus quadripunctatus)

In species showing biparental care, parents often adjust their level of care facultatively. Partners can potentially monitor each other directly (modify their effort sequentially in direct response to the prior effort of their mate) or indirectly (parents modify their effort through the begging rates of their offspring). This study examined whether partner negotiation or begging by larvae best explains male provisioning in Nicrophorus quadripunctatus. The frequency of males approaching larvae to feed did not increase with either female removal or female handicapping. However, larval begging toward males increased with female removal, but not with female handicapping. This suggests that larvae are not affected by the change of female investment in care but larvae reacted to the absence of a female parent. Although larvae begged more towards the male when the female was removed, my findings show that males did not respond by increasing their care, which suggests that males are insensitive to variation in their partner’s state or offspring behaviour in N. quadripunctatus.
