TL;DR: In this paper, the authors assess characteristics of the relationship with their primary investor and compare the results between entrepreneurial firms that had received venture capital funding versus private investor funding, and find that differences were examined along the following lines: 1. • Levels of investor involvement in entrepreneurial firms 2. • Reporting and operational controls placed on the firm 3. • Types of expertise sought by the entrepreneur

TL;DR: The results underscore the risk posed by cultural adjustment problems, the potential for progressive deterioration of this population's mental health, and the need for culturally appropriate mental health services.
Abstract: OBJECTIVES: In this study, the prevalence of and risk factors for 12 psychiatric disorders were examined by sex and ethnicity (Indian vs non-Indian) among Mexican migrant farm-workers working in Fresno County, California. METHODS: Subjects aged 18 through 59 years were selected under a cluster sampling design (n = 1001). A modified version of the Composite International Diagnostic Interview was used for case ascertainment. The effects of sociodemographic and acculturation factors on lifetime psychiatric disorders were tested. RESULTS: Lifetime rates of any psychiatric disorder were as follows: men, 26.7% (SE = 1.9); women, 16.8% (SE = 1.7); Indians, 26.0% (SE = 4.5); non-Indians, 20.1% (SE = 1.3). Total lifetime rates were as follows: affective disorders, 5.7%; anxiety disorders, 12.5%; any substance abuse or dependence, 8.7%; antisocial personality, 0.2%. Lifetime prevalence of any psychiatric disorder was lower for migrants than for Mexican Americans and for the US population as a whole. High acculturation and primary US residence increased the likelihood of lifetime psychiatric disorders. CONCLUSIONS: The results underscore the risk posed by cultural adjustment problems, the potential for progressive deterioration of this population's mental health, and the need for culturally appropriate mental health services.

TL;DR: In this paper, a cross-temporal meta-analysis of U.S. college students' scores on the BSRI (34 samples, N = 8,027), examined changes in ratings on the Bem masculinity (M) and femininity scales since the early 1990s.
Abstract: The Bem Sex-Role Inventory (BSRI) is one of Sandra Bem’s most notable contributions to feminist psychology, measuring an individual’s identification with traditionally masculine and feminine qualities. In a cross-temporal meta-analysis of U.S. college students’ scores on the BSRI (34 samples, N = 8,027), we examined changes in ratings on the Bem masculinity (M) and femininity (F) scales since the early 1990s. Additional analyses used data collected in a previous meta-analysis (Twenge 1997) to document changes since the BSRI’s inception in 1974. Our results reveal that women’s femininity scores have decreased significantly (d = −.26) between 1993 and 2012, whereas their masculinity remained stable. No significant changes were observed for men. Expanded analyses of data from 1974 to 2012 (94 samples, N = 24,801) found that women’s M rose significantly (d = .23), with no changes in women’s F, men’s M, and men’s F. Women’s androgyny scores showed a significant increase since 1974, but not since 1993. Men’s androgyny remained the same in both time periods. Our findings suggest that since the 1990s, U.S. college women have become less likely to endorse feminine traits as self-representative, potentially revealing a devaluation of traditional femininity. However, it is also possible that the scale items do not match modern gender stereotypes. Future research may need to update the BSRI to reflect current conceptions of gender.

TL;DR: Perets et al. as discussed by the authors identified three peculiar transients with five distinguishing characteristics: peak luminosity in the gap between novae and supernovae (M_R ≈ - 15.5 to -16.5), rapid photometric evolution (t_(rise) ≈12-15 days), large photospheric velocities (≈6000 to 11,000 km s^(-1)), early spectroscopic evolution into nebular phase (1 to 3 months) and peculiar nebular spectra dominated by Calcium.
Abstract: From the first two seasons of the Palomar Transient Factory, we identify three peculiar transients (PTF09dav, PTF10iuv, PTF11bij) with five distinguishing characteristics: peak luminosity in the gap between novae and supernovae (M_R ≈ - 15.5 to -16.5), rapid photometric evolution (t_(rise) ≈12-15 days), large photospheric velocities (≈6000 to 11000 km s^(-1)), early spectroscopic evolution into nebular phase (≈1 to 3 months) and peculiar nebular spectra dominated by Calcium. We also culled the extensive decade-long Lick Observatory Supernova Search database and identified an additional member of this group, SN 2007ke. Our choice of photometric and spectroscopic properties was motivated by SN 2005E (Perets et al. 2010). To our surprise, as in the case of SN 2005E, all four members of this group are also clearly offset from the bulk of their host galaxy. Given the well-sampled early and late-time light curves, we derive ejecta masses in the range of 0.4--0.7 M_⊙. Spectroscopically, we find that there may be a diversity in the photospheric phase, but the commonality is in the unusual nebular spectra. Our extensive follow-up observations rule out standard thermonuclear and standard core-collapse explosions for this class of "Calcium-rich gap" transients. If the progenitor is a white dwarf, we are likely seeing a detonation of the white dwarf core and perhaps, even shock-front interaction with a previously ejected nova shell. In the less likely scenario of a massive star progenitor, a very non-standard channel specific to a low-metallicity environment needs to be invoked (e.g., ejecta fallback leading to black hole formation). Detection (or lack thereof) of a faint underlying host (dwarf galaxy, cluster) will provide a crucial and decisive diagnostic to choose between these alternatives.

TL;DR: It is demonstrated that perovskites nanocrystals are exceptional candidates as photocatalysts for fundamental organic reactions, for example C–C, C–N and C–O bond-formations, which may bring new breakthrough in organic chemistry.
Abstract: Nature is capable of storing solar energy in chemical bonds via photosynthesis through a series of C-C, C-O and C-N bond-forming reactions starting from CO2 and light. Direct capture of solar energy for organic synthesis is a promising approach. Lead (Pb)-halide perovskite solar cells reach 24.2% power conversion efficiency, rendering perovskite a unique type material for solar energy capture. We argue that photophysical properties of perovskites already proved for photovoltaics, also should be of interest in photoredox organic synthesis. Because the key aspects of these two applications are both relying on charge separation and transfer. Here we demonstrated that perovskites nanocrystals are exceptional candidates as photocatalysts for fundamental organic reactions, for example C-C, C-N and C-O bond-formations. Stability of CsPbBr3 in organic solvents and ease-of-tuning their bandedges garner perovskite a wider scope of organic substrate activations. Our low-cost, easy-to-process, highly-efficient, air-tolerant and bandedge-tunable perovskites may bring new breakthrough in organic chemistry.
