Statistics poster challenge for schools     

Brad Payne  Jenny Freeman  Eleanor Stillman 《Teaching Statistics》2013,35(1):43-45

The analysis and interpretation of data are important life skills. A poster challenge for schoolchildren provides an innovative outlet for these skills and demonstrates their relevance to daily life. We discuss our Statistics Poster Challenge and the lessons we have learned.  相似文献   

Property of critical excitation for moment-resisting frames subjected to horizontal and vertical simultaneous ground motions     

Kohei Fujita  Izuru Takewaki 《浙江大学学报(A卷英文版)》2009,10(11):1561-1572

It has often been reported that, when building structures are subjected to near-fault earthquake ground motions, horizontal and vertical impulsive inputs may cause critical damage during the first few seconds. In practical design of building structures, however, the safety check, taking into account the effect of multi-component ground motions, is hardly conducted except the design of important structures such as high-rise buildings and nuclear power plants. Ftirthel＇more, it is not clear how the correlation of multi-component ground motions influences the actual safety of structures. In this paper, the detailed property of critical excitation is discussed in association with the relationship between the characteristics of ground motions and those of structures. The properties of various auto power spectral density （PSD） functions of the horizontal and vertical ground motions are investigated, and those of the critical cross PSD function of these two-directional ground motions are found by a devised algorithm in a feasible complex plane. A closed-form expression is derived from the critical relation of the auto PSD functions of the simultaneous inputs. This critical excitation method provides us with a new approach for earthquake-resistant design against the possible future earthquake which causes the critical damages to buildings.  相似文献   

Projecting to the NAEP Scale: Results from the North Carolina End-of-Grade Testing Program     

Valerie S. L. Williams  Kathleen Rees Rosa  Lori D. McLeod  David Thissen  Eleanor E. Sanford 《Journal of Educational Measurement》1998,35(4):277-296

Data from the North Carolina End-of-Grade test of eighth-grade mathematics are used to estimate the achievement results on the scale of the National Assessment of Educational Progress (NAEP) Trial State Assessment. Linear regression models are used to develop projection equations to predict state NAEP results in the future, and the results of such predictions are compared with those obtained in the 1996 administration of NAEP Standard errors of the parameter estimates are obtained using a bootstrap resampling technique.  相似文献   

Contraction and extension of Vorticella and its mechanical characterization under flow loading     

Moeto Nagai  Hiroshi Asai    Hiroyuki Fujita 《Biomicrofluidics》2010,4(3)

We have studied the contraction and extension of Vorticella convallaria and its mechanical properties with a microfluidic loading system. Cells of V. convallaria were injected to a microfluidic channel (500 μm in width and 100 μm in height) and loaded by flow up to ∼350 mm s⁻¹. The flow produced a drag force on the order of nanonewton on a typical vorticellid cell body. We gradually increased the loading force on the same V. convallaria specimen and examined its mechanical property and stalk motion of V. convallaria. With greater drag forces, the contraction distance linearly decreased; the contracted length was close to around 90% of the stretched length. We estimated the drag force on Vorticella in the channel by calculating the force on a sphere in a linear shear flow.  相似文献   

Toward an understanding of higher-order thinking among minority students     

Eleanor Armour-Thomas  Keith Bruno  Brenda A. Allen 《Psychology in the schools》1992,29(3):273-280

Recent investigations have established the importance of higher-order thinking in the acquisition and application of learning skills in diverse domains of inquiry. Such findings have implications for enhancing the quality of thinking of all children but have particular significance for those minority students who historically have not performed as well as their more economically advantaged peers. Although much has been written about the construct, research is still needed to identify the specific processes underlying higher-order thinking and to examine its use among minority populations. A principal-factors extraction with varimax rotation analysis was used in the present study to clarify the nature and function of higher-order thinking among minority students from economically disadvantaged backgrounds. The results allowed for a specification of the mental processes associated with the construct and the extent to which students reported an awareness and use of these processes in academic problem-solving situations.  相似文献

语言与思索--以日语来思索的意义     

藤田正胜 《承德师专学报》2015,(3)

哲学无疑是一门思索普遍性问题的学科，所以或许可以说提出这样一个问题并无必要。不过，即使思索的是普遍性的问题，也脱离不开语言包含的限制性。就日语而言，日语所具有的特点和限制同样影响着使用日语所做的哲学思考。日语有这样一个特点，即一个句子里不总是需要一个主语。它来自于这样的经验，关注的焦点不在于行使者，而在于行使者自身之内。这跟日语“以谓语为中心”的语法结构有关。西田几多郎的“场所”理论是基于他对于康德和新康德主义的认识论的批判之上的。西田特别指出，“我们意识到的意识”固然是在这种认识论中被发现的，但“意识着的意识”却并没被把握到。我们努力发现这样的一个事实，即他对于传统的认识论的批判和他建立的“场所”理论与上面提到的日语中“以谓语为中心”的语法结构有着深刻的关联。这也就明确了，语言对于哲思有着重要的影响。  相似文献   

CONFIDENTIALITY ASSURANCES IN SURVEYS: REASSURANCE OR THREAT?   总被引：2，自引：0，他引：2  

Singer  Eleanor; Hippler  Hans-Jurgen; Schwarz  Norbert 《Int. Journal of Public Opinion Research》1992,4(3):256-268

Over the last three decades, the public's willingness to takepart in surveys has gradually declined, and the decline hasbeen attributed in part to increasing concern about the confidentialityof the data requested. This paper reviews the early literaturebearing on confidentiality assurances and willingness to respond,and then reports on three experiments designed to investigatethe effects of confidentiality on the expectations of respondentsand on their willingness to take part in a survey. The resultsof all three experiments confirm our expectation that confidentialityassurances are not always perceived as reassuring, and do notnecessarily increase the public's willingness to respond.  相似文献
