TL;DR: Japanese socialized and/or immersed in Hokkaido were nearly as likely as European Americans in North America to associate happiness with personal achievement, to show a personal dissonance effect wherein self-justification is motivated by a threat to personal self-images, and to commit a dispositional bias in causal attribution.
Abstract: The authors hypothesized that economically motivated voluntary settlement in the frontier fosters independent agency. While illuminating the historical origin of American individualism, this hypothesis can be most powerfully tested in a region that is embedded in a broader culture of interdependence and yet has undergone a recent history of such settlement. The authors therefore examined residents of Japan's northern island (Hokkaido). Hokkaido was extensively settled by ethnic Japanese beginning in the 1870s and for several decades thereafter. Many of the current residents of Hokkaido are the descendents of the original settlers from this period. As predicted, Japanese socialized and/or immersed in Hokkaido were nearly as likely as European Americans in North America to associate happiness with personal achievement (Study 1), to show a personal dissonance effect wherein self-justification is motivated by a threat to personal self-images (Study 2), and to commit a dispositional bias in causal attribution (Study 3). In contrast, these marker effects of independent agency were largely absent for non-Hokkaido residents in Japan. Implications for theories of cultural change and persistence are discussed.

TL;DR: Highly inert to ionic additions to aldehydes, aryl- and 1-alkenylboronic acids succumb to a catalytic variant mediated by a [Rh(acac)(CO)2 ]-diphosphane complex in aqueous phase at 80-95°C to yield secondary alcohols.
Abstract: Highly inert to ionic additions to aldehydes, aryl- and 1-alkenylboronic acids succumb to a catalytic variant mediated by a [Rh(acac)(CO)2]–diphosphane complex in aqueous phase at 80–95°C to yield secondary alcohols [Eq. (a)]. A key step in the catalytic cycle is the transmetalation between the boron reagent and the rhodium complex. Ln=diphosphane (e.g. 1,1′-bis(diphenylphosphanyl)ferrocene); R=aryl, 1-alkenyl; R′=alkyl, aryl; acac=acetylacetonate.

TL;DR: It is proved that, under the constant population size assumption, the concavity of the function f(S,I) with respect to the number of the infective hosts I ensures the uniqueness and the global stability of the positive endemic equilibrium state.

TL;DR: Besides micro-mechanical interlocking through hybrid-layer formation, self-etch adhesives may benefit from additional chemical interaction between the functional monomer and residual hydroxyapatite, which may account for their lower bonding effectiveness.
Abstract: Besides micro-mechanical interlocking through hybrid-layer formation, self-etch adhesives may benefit from additional chemical interaction between the functional monomer and residual hydroxyapatite. One-step adhesives are commonly associated with lower bonding effectiveness, which must be attributed in part to the dissolution of hydrophilic and hydrophobic monomers in a relatively highly concentrated solvent. In this 'difficult' mixture, also water is essential as ionization medium to enable self-etching activity. Due to the high hydrophilicity, one-step self-etch adhesives have been reported to behave as semi-permeable membranes, allowing fluids to pass through and seriously jeopardizing bond durability. Recent research has also revealed that HEMA-free one-step adhesives are prone to phase-separation, which may also account for their lower bonding effectiveness. Employing an appropriate air-drying technique may, however, improve the bonding effectiveness of such phase-separating adhesives by getting rid of substantially more interfacial water than HEMA-containing adhesives, of which water might be more difficult to remove from.

TL;DR: In this paper, the authors found that recent record lows of Arctic summer sea ice extent are triggered by the Arctic atmospheric DipoleAnomaly (DA) pattern, which produced astrong meridional wind anomaly that drove more sea ice outof the Arctic Ocean from the western to the eastern Arctic into the northern Atlantic during the summers of 1995,1999, 2002, 2005, and 2007.
Abstract: ] Recent record lows of Arctic summer sea ice extentare found to be triggered by the Arctic atmospheric DipoleAnomaly (DA) pattern. This local, second–leading mode ofsea–level pressure (SLP) anomaly in the Arctic produced astrong meridional wind anomaly that drove more sea ice outof the Arctic Ocean from the western to the eastern Arcticinto the northern Atlantic during the summers of 1995,1999, 2002, 2005, and 2007. In the 2007 summer, the DAalso enhanced anomalous oceanic heat flux into the ArcticOceanviaBeringStrait,whichacceleratedbottomandlateralmelting of sea ice and amplified the ice–albedo feedback. Acoupled ice–ocean model was used to confirm the historicalrecord lows of summer sea ice extent.
