Purpose:This study analyzes digital equity realities in U.S.K-12 schools and the role that school leadership plays in digital ***/Approach/Methods:Based on Selwyn's conception of technology as three interlocking elements(access,educational practices,and social context),we applied the ideals of equity and social justice to each of the three elements to conceptualize a framework of digital equity,situating school practice in the larger social,cultural,and political context of the United *** by this framework,we conducted a systematic literature review of the current state of digital equity and school leadership in K-12 ***:The findings demonstrate that U.S.K-12 schools face digital inequity issues,including inequitable access to technology,exclusionary and punitive educational practices using technology,and an unjust social context for technology in *** findings indicate that school leadership plays an important role in digital ***:Based on these findings,we present a framework to assist K-12 leaders in enhancing digital equity,including addressing educational inequities and creating an inclusive social context for the school,ensuring equitable accessibility to technology in schools,and supporting teachers in developing meaningful and equitable practices using technology to address the opportunity gaps encountered by marginalized learners.

High-frequency （〉2 Hz） Rayleigh-wave data acquired with a multichannel recording system have been utilized to determine shear （S）-wave velocities in near-surface geophysics since the early 1980s. This overview article discusses the main research results of high-frequency surface-wave techniques achieved by research groups at the Kansas Geological Survey and China University of Geosciences in the last 15 years. The multichannel analysis of surface wave （MASW） method is a non-invasive acoustic approach to estimate near-surface S-wave velocity. The differences between MASW results and direct borehole measurements are approximately 15% or less and random. Studies show that simultaneous inversion with higher modes and the fundamental mode can increase model resolution and an investigation depth. The other important seismic property, quality factor （Q）, can also be estimated with the MASW method by inverting attenuation coefficients of Rayleigh waves. An inverted model （S-wave velocity or Q） obtained using a damped least-squares method can be assessed by an optimal damping vector in a vicinity of the inverted model determined by an objective function, which is the trace of a weighted sum of model-resolution and model-covariance matrices. Current developments include modeUng high-frequency Rayleigh-waves in near-surface media, which builds a foundation for shallow seismic or Rayleigh-wave inversion in the time-offset domain; imaging dispersive energy with high resolution in the frequency-velocity domain and possibly with data in an arbitrary acquisition geometry, which opens a door for 3D surface-wave techniques; and successfully separating surface-wave modes, which provides a valuable tool to perform S-wave velocity profiling with high-horizontal resolution.

In 2007,the Connecticut Department of Energy and Environmental Protection issued the first Total Maximum Daily Load(TMDL)in the country based not on a specific pollutant or pollutants,but on impervious cover(IC)(Arnold et al.,2010).The water body in question was Eagleville Brook,a small tributary of the Willimantic River in eastern Connecticut that drains a majority of the University of Connecticut *** university is in effect a small city within a largely rural *** as a result of this,there has been a history of“town-gown”tension and controversy with regard to the university’s impact on the water resources of the *** tension reached a climax in September 2005,when a quarter-mile stretch of the Fenton River,which drains the part of campus not in the Eagleville watershed,ran dry(Merritt,2005).Water quantity concerns were frequently joined by water quality concerns,with area residents complaining about the pollution of their drinking water(Morse,2002).Although the Fenton incident precipitated increased efforts on the part of the university to conserve water,efforts to improve the way that campus addressed stormwater issues lagged behind until the advent of the impervious cover *** the intervening eight years since the issuance of the“IC-TMDL”-practically the wink of an eye in the deliberate world of land use decision making-the University of Connecticut campus has become a showcase for green stormwater infrastructure(GSI)practices,also known as low impact development(LID)*** the IC-TMDL served as the catalyst,an environmental regulation,no matter how innovative,cannot in itself produce such dramatic *** this to occur a number of interconnected efforts have to come together,including leadership,research,monitoring,coordination,and education both within and without the university *** paper is an attempt to capture these key elements,consider why they worked(or didn’t),and provide a status report on green storm-water

通过对697名60岁以上、配偶健在的老年人进行调查,对《老年人夫妻依恋问卷》进行修订及信效度的检验,并应用该问卷对老年人的夫妻依恋风格进行划分,考察夫妻依恋风格与一般依恋之间的吻合程度。结果显示修订后的《老年人夫妻依恋问卷》具有稳定的三维度结构以及良好的信效度;聚类分析显示老年人夫妻依恋以安全型和专注型为主,而一般依恋以安全型和冷漠型居多。在老年人中仅有39.9%的个体具有相同类型的夫妻依恋与一般依恋,呈现出较低的一致性。

本文通过分析高压对流扩散湍流燃烧直接数值模拟的高精度结果,研究了复杂燃烧反应中组分扩散过程。在直接数值模拟中,本文使用的组分扩散项在Fick扩散的基础上添加了不同组分扩散、Soret扩散、Dufour扩散、和多组分扩散。计算对比分析了组分扩散在不同环境压力和雷诺数下的区别。此外,为了能够量化的研究高压下组分扩散对燃烧造成的影响,本文推导了用于简化计算的有效扩散因子模型。结果显示,在超过临界压力的情况下,不同组分扩散效应十分显著.且相较于浓度高且分子量大的组分,燃烧过程中产生的低浓度小分子量的组分更易受到其他组分浓度梯度、压力梯度和温度梯度的影响.

在生产可移植的应用软件中已很好地确立了对高级语言和自顶向下设计方法的使用。在系统程序设计中应用同样的原理,就能把可移植性扩展到操作系统本身。虽然 UNIX 操作系统是为特定的计算机(DEC PDP 11)研制的,但是它的简洁和雅致的设计以及细心选择所提供的“原语”,使它成为一个可移植系统的理想候选者。本文描叙了把 UNIX 移植到 Interdata 7/32上的经验。
