Esd Ideas: Why Are Glaciations Slower Than Deglaciations?, Christine J. Ramadhin, Chuixiang Yi
Esd Ideas: Why Are Glaciations Slower Than Deglaciations?, Christine J. Ramadhin, Chuixiang Yi
Publications and Research
The Earth’s climate during the Quaternary is dominated by short warm interglacials and longer cold glaciations paced by external forcings such as changes in insolation. Although not observed in the solar radiation changes, the time series of the cycles display asymmetry since transitions to full glacial conditions are slower than the termination of glaciations. Here an idea is proposed for the slower transition by identifying and describing two negative sea ice feedbacks dominant during the glaciation process that could serve as a control on the intermediate stage and decrease the pace of the process.

Streaming APIs are becoming more pervasive in mainstream Object-Oriented programming languages and platforms. For example, the Stream API introduced in Java 8 allows for functional-like, MapReduce-style operations in processing both finite, e.g., collections, and infinite data structures. However, using this API efficiently involves subtle considerations such as determining when it is best for stream operations to run in parallel, when running operations in parallel can be less efficient, and when it is safe to run in parallel due to possible lambda expression side-effects. ics-preserving fashion. The approach, based on a novel data ordering and typestate analysis, consists of preconditions and …

Many students consider mathematics too abstract and useless for their academic and career goals. Meanwhile, instructors in quantitative disciplines such as economics find many students mathematically underprepared for their courses. The disconnect between students’ perceptions of the utility of mathematics and their life and career may have contributed to some of the under-performance in learning mathematics. Addressing this problem requires collaboration across disciplines to develop an understanding of each other’s needs, more specifically to develop an integrative platform that allows students to apply mathematical skills in interdisciplinary contexts (Ganter & Barker, 2004). We collaboratively designed and implemented an integrative platform …

Degeneracies play a crucial rule in precise scientific measurements as well as in sensing applications. Spherical resonators have a high degree of degeneracy thanks to their highest symmetry; yet, fabricating perfect spheres is challenging because even a stem to hold the sphere breaks the symmetry. Here we fabricate a levitating spherical resonator that is evanescently coupled to a standard optical fiber. We characterize the resonators to exhibit an optical quality factor exceeding a billion, 10 μm radius, and sphericity to within less than 1µ. Using our high quality and sphericity, we experimentally lift degeneracies of orders higher than 200, which …

Prevalence Of Left-Handedness In China 2011: Small-Area Estimates, Hongwei Xu
Prevalence Of Left-Handedness In China 2011: Small-Area Estimates, Hongwei Xu
Publications and Research
Nationally representative survey data and small-area estimation techniques are used to assess the geographic prevalence of left-handedness in China 2011. Measures of individuals’ handedness are their self-reported dominant hand and their hand grip strength, which yield four estimates of left-handed prevalence, and these statistics are recorded at the provincial level. These estimates concord with one another. There are several geographic clusters of high-prevalence rates of left-handers located in ethnic minority-designated autonomous areas or historically revolutionary base areas, which may reflect a deep-rooted sense of defiance to authorities and promote such cultural values as individual autonomy and equality among local people.

The Impact Of A Supplemental Instruction Program On Diverse Peer Leaders At A Two-Year Institution, Sarah Hoiland, Silvia Reyes, Antonio Varelas
Publications and Research
Supplemental Instruction (SI) is a peer-led academic support program in which SI Leaders help students develop study habits and note-taking strategies as well as facilitate test preparation. While the effects of SI on students receiving the instruction have been thoroughly investigated, there have been far fewer studies that have assessed the impact of SI on its Leaders. Furthermore, research on Leaders has yet to adequately consider community colleges or Hispanic-Serving Institutions (HSIs), or to employ qualitative methodologies. Thus, this paper details an SI program developed at a two-year HSI and the impact of the SI Leaders’ experience via qualitative data …

A triflic acid (TfOH) mediated sequential cyclization of ortho-alkynylarylesters and ammonium acetate (NH4OAc) was reported. The reaction took place via a Brønsted acid-mediated intramolecular cyclization of ortho-alkynylarylesters followed by an ammonium acetate participated substitution reaction, forming isoquinolin-1-ones as the major products. Different from most of the known synthetic methods of isoquinolin-1-ones, no metal catalyst was required in the reported reaction. The regioisomers – isoindolin-1-ones were obtained together with isoquinolin-1-ones in a few cases. The intermediate compounds – isochromen-1-ones and isobenzofuran-1-ones were also isolated. The interconversion experiments showed that the regioisomers formed during the Brønsted acid induced …
