AbstractThe Western Sichuan Plateau (WSP), located in the eastern margin of the Qinghai–Tibet Plateau, is the most strongly deformed region of the continental crust in China. Frequent tectonic movements shape the unique topography and landform of the WSP and have also produced abundant geological heritage resources. Based on the existing geological heritage survey data in Sichuan Province, the nearest index analysis method of employing a regional spatial point model was used to reveal the distribution rules and the genetic mechanism of typical geological relics in the WSP for the first time. Results indicate that the formation and distribution of geological relics in the WSP are generally controlled by tectonic movement and supplemented by the comprehensive action of external forces such as flowing water. Their distribution shows a condensed spatial distribution pattern and extends along the strike of a fault zone and river strike strip. Finally, based on the characteristics of geological relics in the WSP, some suggestions on the protection and development of regional geological relics were put forward.

Deferred Annuity

Abstract Unlike defined benefit pensions, 401(k) plans provide little guidance on how to turn accumulated assets into income. The key risk that retirees face is outliving their assets. Insurance against such risk is available through several routes, including immediate annuities, deferred annuities, and additional Social Security through delayed claiming. Under this Social Security bridge option, participants would tap their 401(k) for payments equal to their Social Security to delay claiming. This paper compares these three options in simulations against a baseline in which no assets are used to obtain lifetime income. In each option, assets not allocated to purchasing lifetime income are consumed following the Required Minimum Distribution rules. The analysis finds that, when market and health shocks are included alongside longevity uncertainty, the Social Security bridge option is generally the best for households with median wealth. Wealthier households can benefit from combining the bridge option with a deferred annuity. Part of a symposium sponsored by the Economics of Aging Interest Group.

This paper deals with the static response of a Belleville spring and a diaphragm spring by using the finite rotation and large deflection theories of a beam and conical shell, and an experimental method as well. The authors propose new mechanical analysis mathematical models. The exact solution of a variable width cantilever beam is obtained. By using the integral equation method and the iterative method to solve the simplified equations and Reissner’s equations of finite rotation and large deflection of a conical shell, this paper has calculated a great number of numerical results. The properties of loads, strains, stresses and displacements, and the distribution rules of strains and stresses of diaphragm springs are investigated in detail by means of the experimental method. The unreasonableness of several assumptions in traditional theories and calculating method is pointed out.

Three- to five-year-old children produce speech that is characterized by a high level of variability within and across individuals. This variability, which is manifest in speech movements, acoustics, and overt behaviors, can be input to subgroup discovery methods to identify cohesive subgroups of speakers or to reveal distinct developmental pathways or profiles. This investigation characterized three distinct groups of typically developing children and provided normative benchmarks for speech development. These speech development profiles, identified among 63 typically developing preschool-aged speakers (ages 36–59 mo), were derived from the children's performance on multiple measures. These profiles were obtained by submitting to a k-means cluster analysis of 72 measures that composed three levels of speech analysis: behavioral (e.g., task accuracy, percentage of consonants correct), acoustic (e.g., syllable duration, syllable stress), and kinematic (e.g., variability of movements of the upper lip, lower lip, and jaw). Two of the discovered group profiles were distinguished by measures of variability but not by phonemic accuracy; the third group of children was characterized by their relatively low phonemic accuracy but not by an increase in measures of variability. Analyses revealed that of the original 72 measures, 8 key measures were sufficient to best distinguish the 3 profile groups.
