The changing structure of American innovation: Some cautionary remarks for economic growth. Ashish Arora, Sharon Belenzon, Andrea Patacconi, Jungkyu Suh. NBER Working Paper No. 25893, May 22, 2019. https://www.nber.org/chapters/c14259.pdf
Abstract: A defining feature of modern economic growth is the systematic application of science to advancetechnology. However, despite sustained progress in scientific knowledge, recent productivity growth in the U.S. has been disappointing. We review major changes in the American innovation ecosystem over the past century. The past three decades have been marked by a growing division of labor between universities focusing on research and large corporations focusing ondevelopment. Knowledge produced by universities is not often in a form that can be readily digested and turned into new goods and services. Small firms and university technology transfer offices cannot fully substitute for corporate research, which had integrated multiple disciplinesat the scale required to solve significant technical problems. Therefore, whereas the division ofinnovative labor may have raised the volume of science by universities, it has also slowed, at leastfor a period of time, the transformation of that knowledge into novel products and processes.
---
In this chapter, we suggest that this division of innovative labor has not, perhaps, lived up to its promise. The translation of scientific knowledge generated in universities to productivity enhancing technical progress has proved to be more difficult to accomplish in practice than expected. Spinoffs, startups, and university licensing offices have not fully filled the gap left by the decline of the corporate lab. Corporate research has a number of characteristics that make it very valuable for science-based innovation and growth. Large corporations have access to significant resources, can more easily integrate multiple knowledge streams, and direct their research toward solving specific practical problems, which makes it more likely for them to produce commercial applications. University research has tended to be curiosity-driven rather than mission-focused. It has favored insight rather than solutions to specific problems, and partly as a consequence, university research has required additional integration and transformation to become economically useful. This is not to deny the important contributions that universities and small firms make to American innovation. Rather, our point is that large corporate labs may have distinct capabilities which have proved to be difficult to replace.

‘I see you sharing, thus I share with you’: indirect reciprocity in toddlers (18-24 mos.) but not infants (6 mos.)
‘I see you sharing, thus I share with you’: indirect reciprocity in toddlers but not infants. Elena Nava, Emanuela Croci & Chiara Turati. Palgrave Communications 5, Article number: 4 (2019). https://www.nature.com/articles/s41599-019-0268-z
Abstract: Human societies are organised around cooperative interactions, the origins and development of which have become a timely topic. In this study, we investigated the development of indirect reciprocity in 18–24-month-old toddlers, and infants aged 6 months, on a two-phase sharing task with non-familiar individuals. In the first phase, we observed whether infants and toddlers differentiated and manifested a preference toward an individual altruistically sharing or acting selfishly. In the second phase, infants and toddlers interacted with the same prosocial and antisocial individuals seen in the first phase, and we observed whether they were willing to share with one of the two. Indirect reciprocity was assessed as the match between the preferences for the prosocial individual in phase one, and the first-person sharing in the second phase. Evidence showed that toddlers, but not infants, indirectly reciprocated the prosocial individual, suggesting that understanding of such a complex behaviour as indirect reciprocity may require prolonged experience in order to emerge.

Can events be accurately described as historic at the time they are happening?
Predicting history. Joseph Risi, Amit Sharma, Rohan Shah, Matthew Connelly & Duncan J. Watts. Nature Human Behaviour (2019). June 3 2019. https://www.nature.com/articles/s41562-019-0620-8
Abstract: Can events be accurately described as historic at the time they are happening? Claims of this sort are in effect predictions about the evaluations of future historians; that is, that they will regard the events in question as significant. Here we provide empirical evidence in support of earlier philosophical arguments1 that such claims are likely to be spurious and that, conversely, many events that will one day be viewed as historic attract little attention at the time. We introduce a conceptual and methodological framework for applying machine learning prediction models to large corpora of digitized historical archives. We find that although such models can correctly identify some historically important documents, they tend to overpredict historical significance while also failing to identify many documents that will later be deemed important, where both types of error increase monotonically with the number of documents under consideration. On balance, we conclude that historical significance is extremely difficult to predict, consistent with other recent work on intrinsic limits to predictability in complex social systems2,3. However, the results also indicate the feasibility of developing ‘artificial archivists’ to identify potentially historic documents in very large digital corpora.

Individuals in committed relationahips with a high position engaged in all types of online sexual activity more frequently; perceived position and sense of power significantly predicted OSAs
The influence of power on online sexual activities among Chinese men and women in committed relationships. Guangju Wen, Lijun Zheng. Personality and Individual Differences, Volume 149, 15 October 2019, Pages 88-93. https://doi.org/10.1016/j.paid.2019.05.032
Highlights
• Individuals with a high position engaged in all types of OSA more frequently.
• Perceived position and sense of power significantly predicted OSA.
• Attitude toward infidelity mediated the relationship between power and OSA.
Abstract: Power has been empirically demonstrated to influence infidelity. This study investigated the influence of power on online sexual activity (OSA), as a form of online infidelity, among Chinese men and women in committed relationships. We also explored the potential mediating effect of attitude toward infidelity on the relationship between power and OSA. We hypothesized that powerful individuals would engage in OSA more frequently than would less powerful individuals. Participants (N = 425) completed questionnaires assessing their OSA experience within the past 12 months, as well as their own sense of power and their attitude toward infidelity. The OSAs were categorized as viewing sexually explicit material, sexual partner seeking, cybersex, and flirting. Three aspects of power were measured: position, perceived power, and sense of power. The results showed that individuals with higher positions engaged in all types of OSA more frequently than did individuals with lower positions. Power, a latent variable comprising perceived power and sense of power, also significantly predicted OSA, while attitude toward infidelity played a mediating role in this relationship. The findings demonstrate a common mechanism underlying the effect of power on both offline and online infidelity.

Compared to the participants lower in dark traits, those with higher narcissism & boldness reported higher sexual motivation, sexual self-esteem & sexual assertiveness & lower negative emotions in sex
The Dark Triad and the quality of sexual life. Irena Pilch, Klaudia Smolorz. Personality and Individual Differences, Volume 149, 15 October 2019, Pages 78-82. https://doi.org/10.1016/j.paid.2019.05.041
Abstract: This study investigated sexual functioning with respect to differences in the Dark Triad traits in a large community sample (N = 1116). The participants completed an online survey examining dark traits (Machiavellianism, narcissism, and psychopathy domains: boldness, meanness and disinhibition) and measures of sexual functioning. The Dark Triad traits were positively associated with sexual preoccupation in both sexes. Compared to the participants lower in dark traits, those with higher narcissism and boldness reported higher sexual motivation, sexual self-esteem and sexual assertiveness and lower negative emotions in the sexual context, which can be interpreted as higher quality of their sexual experience. In turn, those higher in Machiavellianism and disinhibition reported higher sexual fear and anxiety; women additionally showed lower sexual self-esteem and/or sexual assertiveness. Boldness was the only dark trait positively related to sexual satisfaction, especially in men.

Women who faked orgasm in order to elevate their own sexual arousal had greater orgasm consistency; opposite for women who faked orgasm out of fear or insecurity
Motivations for faking orgasm and orgasm consistency among young adult women. Michael D. Barnett et al. Personality and Individual Differences, Volume 149, 15 October 2019, Pages 83-87. https://doi.org/10.1016/j.paid.2019.05.031
Abstract: Women fake orgasm for partner-focused reasons and self-focused reasons, the latter of which include elevating their own sexual arousal. The purpose of this study was to investigate the relationships between motivations for faking orgasm and orgasm consistency within the sexual activities of receiving oral sex and sexual intercourse among young adult women (N = 998). For both receiving oral sex and sexual intercourse, women who faked orgasm in order to elevate their own sexual arousal had greater orgasm consistency, whereas women who faked orgasm out of fear or insecurity had lower orgasm consistency. Overall, the results suggest that self-focused motivations for faking orgasm – particularly elevating arousal – are more closely associated with orgasm consistency than partner-focused motivations for faking orgasm.
