Though it's many a person's first sexual activity, masturbation isn't only for solo play ? it may be even more fun with company! Masturbation with more than yourself is often referred to as mutual masturbation. Whether solo or social, this activity is concsidered one of the safer forms of sex play. However, as you suggest, there is a risk of transporting your little swimmers to your partner. Bu...

Timbre is a major cue for the human auditory system to recognize musical sounds. Timbral patterns can be decomposed in the widely used spectral envelope and the less considered temporal dynamics. In this paper, we present new temporal dynamics similarity measures, which will prove valuable for the recognition of timbral patterns. These similarity measures are evaluated, first alone, then in con...

Peterson et al raise important issues about the decline in the proportion of solo practitioners in primary care and whether it will have a detrimental effect on access to care in rural areas. They use practice organization data provided by family physicians who took the American Board of Family Medicine’s recertification examination in 1993, 1998, 2003, 2008, and 2013 to track the proportion of...

We have used 19.9 million papers over 5 decades and 2.1 million patents to demonstrate that teams increasingly dominate solo authors in the production of knowledge. Research is increasingly done in teams across nearly all fields. Teams typically produce more frequently cited research than individuals do, and this advantage has been increasing over time. Teams now also produce the exceptionally ...

When it was introduced in the Affordable Care Act of 2010 as the new 2012 payment model for Medicare, an accountable care organization (ACO) was a new and untested concept in healthcare delivery and payment. The authors estimated the likelihood of engagement in ACOs by small group and solo healthcare practitioners. An evaluation of five case studies showed that significant organizational, finan...

This paper presents an automatic accompaniment system for jazz that understands solist’s intention of improvising and outputs expressive accompaniment of a bass guitar and drums reacting to solo. Previous systems extracted just one parameter as solist’s intention and output accompaniment by switching registered patterns. Our system can understand solist’s intention in more detail by extracting ...

This study presents an effective technique for automatically identifying the singer of a music recording. Since the vast majority of popular music contains background accompaniment during most or all vocal passages, directly acquiring isolated solo voice data for extracting the singer’s vocal characteristics is usually infeasible. To eliminate the interference of background music for singer ide...

Two studies examined how parent explanation changes what children learn from everyday shared scientific thinking. In Study 1, children between ages 3and 8-years-old explored a novel task solo or with parents. Analyses of children's performance on a subsequent posttest compared three groups: children exploring with parents who spontaneously explained to them; children exploring with parents who ...

We used structure-mapping theory (Gentner, 1983) to study learning in negotiation teams. We instructed some teams to compare two training cases and identify a key negotiation principle; other teams were given the same two cases to study and analyze separately. Teams who compared the two cases during the training period were more likely to transfer a key value-added strategy to a novel face-to-f...
