Six steps for building a technological knowledge base for future taxonomic workOA

<正>Species are the principal category we use to study,understand,and conserve the natural world,so how we define species has a cascading impact across fields,well beyond biology [1].Despite such importance,debate on species concepts continues to this day ([2] 2020),with consequences for what organisms we recognize,study and protect.Given the wealth of life forms on our planet,     

Holistic face processing in newborns, 3-month-old infants, and adults: evidence from the composite face effect

Holistic face processing was investigated in newborns, 3-month-old infants, and adults through a modified version of the composite face paradigm and the recording of eye movements. After familiarization to the top portion of a face, participants (N = 70) were shown 2 aligned or misaligned faces, 1 of which comprised the familiar top part. In the aligned condition, no visual preference was found at any group age. In the misaligned condition, 3-month-olds preferred the face stimulus with the familiar top part, adults preferred the face stimulus with the novel one, and newborns did not manifest any visual preference. Results revealed that both infants' and adults' eye movements may be affected by holistic face information and demonstrated holistic face processing in 3-month-olds.     

学习科学的基本问题

学习科学的问题是,尽管我们对它知之甚多,但是行动起来还是困难重重.虽然我关注K12教育比关注大学多,但在这里我要写大学教育,因为大学应是最容易改革的教育机构.从大学开始变革有许多好的理由,但在大学教育中进行有意义的变革多少有些不太可能.     

Self-Regulation and School Readiness

RESEARCH FINDINGS: In this article, we review research on the relations of self-regulation and its dispositional substrate, effortful control, to variables involved in school success. First, we present a conceptual model in which the relation between self-regulation/effortful control and academic performance is mediated by low maladjustment and high-quality relationships with peers and teachers, as well as school engagement. Then we review research indicating that effortful control and related skills are indeed related to maladjustment, social skills, relationships with teachers and peers, school engagement, as well as academic performance. PRACTICE OR POLICY: Initial findings are consistent with the view that self-regulatory capacities involved in effortful control are associated with the aforementioned variables; only limited evidence of mediated relations is currently available.     

Using food as a tool to teach science to 3 grade students in Appalachian Ohio

The Food, Math, and Science Teaching Enhancement Resource (FoodMASTER) Initiative is a compilation of programs aimed at using food as a tool to teach mathematics and science. In 2007-2008, a foods curriculum developed by professionals in nutrition and education was implemented in 10 3(rd)-grade classrooms in Appalachian Ohio; teachers in these classrooms implemented 45 hands-on foods activities that covered 10 food topics. Subjects included measurement; food safety; vegetables; fruits; milk and cheese; meat, poultry, and fish; eggs; fats; grains; and meal management. Students in four other classrooms served as the control group. Mainstream 3(rd)-grade students were targeted because of their receptiveness to the subject matter, science standards for upper elementary grades, and testing that the students would undergo in 4(th) grade. Teachers and students alike reported that the hands-on FoodMASTER curriculum experience was worthwhile and enjoyable. Our initial classroom observation indicated that the majority of students, girls and boys included, were very excited about the activities, became increasingly interested in the subject matter of food, and were able to conduct scientific observations.     

在GPU加速的集群上应用一个消息驱动的并行程序

GPU因其高性能和硬件灵活性,以及各种通用上的用于科学计算的GPU软件开发工具的产生,已经被成为加速科学运算速度的有效手段。然而在集群中高效地使用GPU却带来很多软件开发和系统集成方面的拐点。我们给出了一种分解和调度CPU计算和GPU内核执行的策略。我们的报告指出这种技术应用在NAMD（一种广泛使用的并行分子动态模拟程序包）,在一个由64个64核GPU组成的集群上所体现出来的优势。     

Reading skills in early readers: genetic and shared environmental influences

The present study combined parallel data from the Northeast-Northwest Collaborative Adoption Projects (N2CAP) and the Western Reserve Reading Project (WRRP) to examine sibling similarity and quantitative genetic model estimates for measures of reading skills in 272 school-age sibling pairs from three family types (monozygotic twins, dizygotic twins, and unrelated adoptive siblings). The study included measures of letter and word identification, phonological awareness, phonological decoding, rapid automatized naming, and general cognitive ability. Estimates of additive genetic effects and shared environmental effects were moderate and significant. Furthermore, shared environmental effects estimated in twins were generally similar in magnitude to adoptive sibling correlations, suggesting highly replicable estimates across different study designs.     

EndNote and Reference Manager Citation formats compared to "instructions to authors" in top medical journals

The study compared citation format in EndNote version 7 and Reference Manager version 11 with the citation format for references found in the instructions to authors from the most significant medical literature. The resulting information should be very useful to those who depend on citation management software to format and organize their references for publication in medicine, and librarians and others who teach the use of citation management software.
