On September 14, 2015 at 09:50:45 UTC the two detectors of the Laser Interferometer Gravitational-Wave Observatory simultaneously observed a transient gravitational-wave signal. The signal sweeps upwards in frequency from 35 to 250 Hz with a peak gravitational-wave strain of 1.0×10(-21). It matches the waveform predicted by general relativity for the inspiral and merger of a pair of black holes and the ringdown of the resulting single black hole. The signal was observed with a matched-filter signal-to-noise ratio of 24 and a false alarm rate estimated to be less than 1 event per 203,000 years, equivalent to a significance greater than 5.1σ. The source lies at a luminosity distance of 410(-180)(+160)  Mpc corresponding to a redshift z=0.09(-0.04)(+0.03). In the source frame, the initial black hole masses are 36(-4)(+5)M⊙ and 29(-4)(+4)M⊙, and the final black hole mass is 62(-4)(+4)M⊙, with 3.0(-0.5)(+0.5)M⊙c(2) radiated in gravitational waves. All uncertainties define 90% credible intervals. These observations demonstrate the existence of binary stellar-mass black hole systems. This is the first direct detection of gravitational waves and the first observation of a binary black hole merger.

“WHAT can men do, what do they do, and what do they want to do ?”—these are the uestions that Prof. Thorndike seeks to answer in a very comprehensive and elaborate treatise. His undertaking is inspired by the belief that man has the possibility of almost complete control of his fate if only he will be guided by science, and that his failures are attributable to ignorance or folly. The main approach is through biological psychology, but all the social sciences are appealed to and utilized in an effort to deal with the human problem as a whole. The relative immaturity of the sciences dealing with man is continually stressed, but it is claimed that they provide a body of facts and principles which are “far above zero knowledge”, and that even now they are capable of affording valuable guidance in the shaping of public policy.

Human Nature and the Social Order

Objectification theory (Fredrickson B. L., & Roberts, T. A. (1997). Psychology of Women Quarterly, 21, 173-206) proposes that body image concerns impair sexual function and satisfaction. The present study was designed to test whether body shame was related to sexual problems and pleasure among heterosexual men and women (N = 320). Using structural equation modeling, we tested whether adult men and women's body shame was linked to greater sexual problems (lower sexual arousability and ability to reach orgasm) and less pleasure from physical intimacy. Although women were significantly more likely to report appearance concerns than men across sexual and non-sexual contexts, appearance concerns were positively related to both men and women's sexual problems. The relationship between body shame and sexual pleasure and problems was mediated by sexual self-consciousness during physical intimacy. Men and women's body shame was related to greater sexual self-consciousness, which in turn predicted lower sexual pleasure and sexual arousability. Results persisted controlling for relationship status and age. Being in a relationship was associated with less sexual self-consciousness and less orgasm difficulty for men and women. Although some paths were significantly stronger for women than for men, results largely supported the proposition that body concerns negatively affect sexual pleasure and promote sexual problems for both men and women. Findings were discussed in terms of objectification theory and the increased cultural emphasis on physical appearance.

Body concerns in and out of the bedroom: implications for sexual pleasure and problems.

Much attention has been directed toward understanding the impact having a multiracial background has on psychological well-being and adjustment. Past psychological research has focused on the challenges multiracial individuals confront in defining a racial identity. The implication is that these challenges lead to outcomes that are psychologically detrimental. However, evidence to support this assertion is mixed. The authors review qualitative and quantitative empirical research examining multiracial individuals' identity development, depression, problem behaviors, peer relationships, school performance, and self-esteem, finding support for detrimental outcomes only in studies sampling clinical populations. Studies on nonclinical samples find that multiracial individuals tend to be just as well-adjusted as their monoracial peers on most psychological outcomes. Earlier assertions of maladjustment may have been due to reliance on qualitative research that sampled clinical populations. Other implications and future research are discussed.

Perspectives and research on the positive and negative implications of having multiple racial identities.

People often believe that they must be consistent with gender norms to obtain others' approval. The authors believe people who invest in gender norms tend to base self-esteem on others' approval, which undermines their sexual autonomy and ultimately diminishes their sexual satisfaction in intimate relationships. A survey of 309 sexually active college students examined whether placing importance on conforming to gender norms undermines sexual relationships because of its link to basing self-worth on others' approval and decreased sexual autonomy. Using structural equation modeling, the authors found that valuing gender conformity (but not avoiding gender deviance) negatively affects sexual pleasure for both men and women through increased contingency on others' approval and restricted sexual autonomy. The model fit the data for both men and women.

Multiracial individuals are more likely to have a heightened awareness of race as a social construct than monoracial individuals. This article examines the impact that a heightened awareness of race as a social construct has on the relationship between racial stereotypes and performance. Study 1 finds that multiracial individuals reported subscribing less to the notion that race biologically determines ability. Study 2 finds that monoracial individuals show stereotype activation, whereas multiracial individuals show stereotype inhibition in reaction to race salience. Study 3 draws on the work on stereotypes and performance to test the susceptibility of multiracial individuals to racial stereotypes about ability. The authors find that Asian/White and Black/White multiracial individuals were less susceptible to racial stereotypes than monoracial individuals. Whereas monoracial participants showed significant performance changes in reaction to race salience, multiracial individuals did not. Study 4 finds that emphasizing the social construction of race buffers individuals from stereotype threat effects.
