This project sheds light on men's choice in the face of threats to their masculinity: to compensate to appear more masculine or to revise their definitions of manhood. Research has demonstrated that men overcompensate in their displays of masculinities when faced with challenges to their dominant status. However, not all men pursue dominant displays of masculinity through heterosexuality: Older men (85+) may abandon ideals of masculinity tied to sexual dominance as they once did in middle age. This dissertation weaves together men's three distinct pursuits of dominant manhood: approval of violence against women (AVAW), changes to sexual function in old age (i.e., flaccidity or erectile dysfunction), and sugar dating (i.e., dating between younger women and an older man, in which money is exchanged for intimacy). I show that men's use of compensatory heterosexuality offers them a way to do gender when confronted with threatened masculinity in the form(s) of subordination to women, sexual dysfunction, and older age. In each project, men rely on displays of heterosexual dominance and objectification of women as a compensatory means to do masculinity. However, their reliance on heterosexuality is subject to change under such conditions as older age, which can lead to revisions of manhood. / Doctor of Philosophy / This project sheds light on men's choices in the face of gender threats: to compensate to appear more masculine or to revise or change their definitions of manhood. Research has demonstrated that men overdo their displays of masculinity when faced with challenges. However, not all men do this: Older men (85+) may move away from a masculinity tied to sexual displays as they once did in middle age. This dissertation weaves together three displays of masculinity: approval of violence against women (AVAW), changes to sexual function in old age (i.e., flaccidity or erectile dysfunction), and sugar dating (i.e., dating between a younger woman and an older man in which money is exchanged for emotional and physical relationships). These avenues offer men a way to perform their masculinities when confronted with threats in the form(s) of subordination to women (i.e., women in power over you), sexual dysfunction, and older age. In each project, men rely on displays of sexual dominance and objectification of women to perform masculinity (when compensating). However, their reliance on these displays is subject to change under certain conditions (when revising manhood).

Avaliar a biocompatibilidade do fio lifting biológico - fio serrilhado de poliuretana de óleo de mamona - e sua eficácia no rejuvenescimento facial. Na primeira etapa deste trabalho implantamos os fios no dorso de camundongos, que foram sacrificados com 03, 07, 15 e 30 dias com posterior análise histológica por microscopia óptica. Na segunda fase implantamos os fios na face de pacientes com flacidez dérmica e analisamos, fotograficamente e através de uma modelagem numérico-computacional o resultado (rejuvenescimento), com intervalos entre 07 e 60 dias. As análises histológicas demonstraram uma rápida integração do fio ao tecido celular subcutâneo com formação abundante de colágeno e as fotografias dos pacientes revelaram uma maior firmeza da derme e um rejuvenescimento facial, comprovados pela análise computacional. Suas características químicas e físicas e os resultados iniciais nos permitem acreditar que o fio lifting biológico - fio serrilhado de poliuretana do óleo de mamona - apresenta elevada biocompatibilidade com uma rápida integração ao tecido subcutâneo sendo uma excelente opção no rejuvenescimento facial. / Evaluate the biological lifting thread - castor oil polyurethane serrulate thread - bio-compatibility and it´s eficacy on facial rejuvenation. At first we implanted the threads in subcutaneous tissues on mice backs that were sacrificed after 03, 07, 15 and 30 days, followed by histological analysis of material by using optical microscopy. Later, implants were carried out in patients with facial dermal flaccidity, and comparisons were made through photographs between 7 and 60 days, than we made a numerical-computational modelling comparision of this photographs. Histological analysis showed a quick thread integration with the celular subcutaneous tissue by a large amount of colagen syntesis and the patients photographs showed facial rejuvenation with improvement of the skin flaccidity comproved by numerical modelling. It`s chemical and physical characteristics and the initial results allow us belive that the biological lifting thread - castor oil polyurethane serrulate thread - has good bio-compatibility and fast integration with the celular subcutaneous tissue being an excellent option for the facial rejuvenation.
