Is Ageism Alive in Date Selection Among Men? Age Requests Among Gay and Straight Men in Internet Personal Ads

We examine 2,400 personal ads from male advertisers collected from the Internet, focusing on age preference by race and sexual orientation. We look at whether advertisers display any age preference in personal ads and whether the preference varies by race and sexual orientation. We find that gay men are more likely than straight men to state an age preference. Also, the preference for younger partners intensified among the older advertisers regardless of race and sexual orientation. Youth is still a treasured commodity in date selection for men. However, some men, especially gay men, prefer more mature partners. At least 20 percent of gay Asian men in all three age groups prefer older partners. Further research is recommended to explore this exception among gay Asian men

Adaptive Physically Based Models in Computer Graphics

International audienceOne of the major challenges in physically-based modeling is making simulations efficient. Adaptive models provide an essential solution to these efficiency goals. These models are able to self-adapt in space and time, attempting to provide the best possible compromise between accuracy and speed. This survey reviews the adaptive solutions proposed so far in computer graphics. Models are classified according to the strategy they use for adaptation, from time-stepping and freezing techniques to geometric adaptivity in the form of structured grids, meshes, and particles. Applications range from fluids, through deformable bodies, to articulated solids

Gendered parental leave policies among Fortune 500 companies

This is an Accepted Manuscript of an article published by Taylor & Francis in Community, Work & Family on August 6, 2020, available at: http://www.tandfonline.com/10.1080/13668803.2020.1804324.Due to the lack of a federal paid parental leave policy in the United States, access to leave for most US workers is dependent on whether their employer offers paid leave. Our research explores employer-based access to parental leave among Fortune 500 companies. We develop a classification of leave policies based on how policies differ for mothers and fathers: gender equal (equal periods of leave to mothers and fathers), gender modified (equal leave of 6 or more weeks with an additional 6–8 weeks for mothers), gender unequal (mothers offered 2 or more times longer leave than fathers), and gender-neutral gendering (policies that offer primary and secondary caregiver leave). We find that 72% of companies offer some paid parental leave, and the majority of Fortune 500 companies have paid parental leave policies that offer substantially more leave to mothers than to fathers. We also find that technology companies, larger companies, and companies headquartered in a state with paid family leave are more likely to offer paid parental leave. This research provides insight into the degree to which employer policies may contribute to gender inequality and has implications for employer-mediated inequalities in access to parental leave

Post-birth employment leave among fathers in Britain and the United States

This study examines fathers' use of family leave in Britain and the US. Using data from interviews with 83 working fathers in Britain and the United States, we find that almost all fathers take some leave, but British fathers take more leave on average while American fathers demonstrate a wider range of leave time. Much of this has to do with the national context within which these men experience becoming a father. British fathers commonly took one week of paid leave, a taken for granted benefit. Most American fathers, faced with unpaid leave, used vacation days to take time off around the birth of their child. In some cases, it was unclear how leave was counted. Other themes include difficulties with "family unfriendly" employers and the desire for more time off and better leave policies

The Return of Diadema antillarum to Discovery Bay: Patterns of Distribution and Abundance

By 1999, populations of the sea urchin Diadema antillarum had begun a dramatic resurgence on the north coast of Jamaica after 23 years of stasis at very low levels. This increase in D. antillarum, from population levels near zero in 1984 to densities as high as 16 m2 in 2000, is associated with increases in abundance of the sympatric echinoids Echinometra viridis and Eucidaris tribuloides. In contrast, Tripneustes ventricosus was abundant on the fore reef in 1999 (unusual in that T. ventricosus generally inhabits back reef environments) but declined dramatically by 2000. Geographical Information Systems (GIS) analysis showed that D. antillarum rarely occurred alone: in 1999 and 2000, D. antillarum co-occurred with a second urchin species in 89.95% and 65.47% of the area surveyed respectively. Findings suggest that interactions between members of the echinoid complex are potentially important for reef recovery. Recent research conducted on the recovery of the D. antillarum population suggest that the presence of T. ventricosus on the fore reef may have created a disturbance large enough to facilitate a phase transition from algal to coral dominated substratum (Woodley et al. 1999). Our results are consistent with the findings of Woodley et al. (1999). We propose that recruitment of D. antillarum is facilitated by the presence of sympatric echinoids and is not dependent upon food availability. Sizes of D. antillarum populations at five sites were normally distributed, indicating strong, continued recruitment and suggesting that conditions conducive to reef recovery on the north coast of Jamaica have begun.This article was originally published at http://www.reefbase.org/download/download.aspx?type=1&docid=1231

‘We both need to work’

Both Britain and the USA are described as market-oriented or ‘liberal’ welfare regimes. However, there are important variations within these two countries: although both have high rates of maternal employment, part-time work is much more common in the UK than in the USA, where dual-earner (full-time) couples are the norm. Part-time employment can help to ease work-family conflict for women, while simultaneously contributing to the household income. However, part-time work is limited in its economic benefits, is also career limiting, and, in the USA, it generally comes without health insurance. While most of the current research regarding maternal employment decisions focuses on women, this research involves interviews with 83 British and American fathers, to better understand the complexity of such decision-making. Men’s attitudes and experiences are examined in detail, focusing on the need for two incomes, the importance of paid health care and childcare costs and the potential role of part-time work.childcare; fathers; health insurance; maternal employment; part-time
