Who Are the Givers? Briefing Paper on British Social Attitudes to Charitable Giving

This Institute for Philanthropy paper summarizes the findings of the annual British Social Attitudes Survey on the attitudes and values of Britons regarding charitable giving and philanthropy, and on their behavior. The authors differentiate the target group by age, education, religion, income, political affiliation, and newspaper readership, and determines that there are broadly three groups in British society: contributors, bystanders, and investors

Subject Unrest

Roll-to-roll manufacturing of micro components based on advanced printing, structuring and lamination of ceramic tapes is rapidly progressing. This large-scale and cost-effective manufacturing process of ceramic micro devices is however prone to hide defects within the visually opaque tape stacks. To achieve a sustainable manufacturing with zero defects in the future, there is an urgent need for reliable inspection systems. The systems to be developed have to perform high-resolution in-process quality control at high speed. Optical coherence tomography (OCT) is a promising technology for detailed in-depth inspection and metrology. Combined with infrared screening of larger areas it can solve the inspection demands in the roll-to-roll ceramic tape processes. In this thesis state-of-art commercial and laboratory OCT systems, operating at the central wavelength of 1.3 µm and 1.7 µm respectively, are evaluated for detecting microchannels, metal prints, defects and delaminations embedded in alumina and zirconia ceramic layers at hundreds of micrometers beneath surfaces. The effect of surface roughness induced scattering and scattering by pores on the probing radiation, is analyzed by experimentally captured and theoretically simulated OCT images of the ceramic samples, while varying surface roughnesses and operating wavelengths. By extending the Monte Carlo simulations of the OCT response to the mid-infrared the optimal operating wavelength is found to be 4 µm for alumina and 2 µm for zirconia. At these wavelengths we predict a sufficient probing depth of about 1 mm and we demonstrate and discuss the effect of rough surfaces on the detectability of embedded boundaries. For high-precision measurement a new and automated 3D image processing algorithm for analysis of volumetric OCT data is developed. We show its capability by measuring the geometric dimensions of embedded structures in ceramic layers, extracting features with irregular shapes and detecting geometric deformations. The method demonstrates its suitability for industrial applications by rapid inspection of manufactured samples with high accuracy and robustness. The new inspection methods we demonstrate are finally analyzed in the context of measurement uncertainty, both in the axial and lateral cases, and reveal that scattering in the sample indeed affects the lateral measurement uncertainty. Two types of image artefacts are found to be present in OCT images due to multiple reflections between neighboring boundaries and inhomogeneity of refractive index. A wavefront aberration is found in the OCT system with a scanning scheme of two galvo mirrors, and it can be corrected using our image processing algorithm.QC 20140428Multilayer (FP7-NMP4-2007-214122

The Law and Economics of Critical Race Theory

Legal academics often perceive law and economics (L&E) and critical race theory (CRT) as oppositional discourses. Using a recently published collection of essays on CRT as a starting point, we argue that the understanding of workplace discrimination can be furthered through a collaboration between L&E and CRT. L&E\u27s strength is in its attention to incentives and norms, specifically its concern with explicating how norms incentivize behavior. Its limitation is that it treats race as exogenous and static. Thus, the literature fails to consider how institutional norms affect, and are affected by, race. To put the point another way, L&E does not discuss how norms incentivize racial behavior, obscuring that how people present their race (or themselves as racial subjects) is a function of norms. The strength of CRT is its conception of race as a social construction. Under this view, race is neither biologically determined nor fixed. Instead, race is ever evolving as a function of social, political, legal, and economic pressures. A limitation of CRT is that much of its analysis of race as a social construction is macro-oriented. Thus, CRT has paid insufficient attention to the social construction of race within specific institutional settings, like the workplace. Further, CRT has virtually ignored the agency people of color exercise to shape how their racial identity is interpreted - that is say, constructed. Explicitly incorporating L&E\u27s focus on incentives and norms into CRT provides CRT with a means by which to articulate the notion of race as a social construction at the level of individual choice. The basic idea is that people of color construct (present racial impressions of) themselves in response to norms. Norms, in this sense, are racially productive, and individuals are part of the production apparatus. Having set out the basic elements of the collaborative enterprise, we deploy this collaboration to respond to a specific and important question about the workplace: How are modern employers and employees likely to manage workplace racial diversity? We raise this question because we assume that, for institutional legitimacy reasons, most workplaces will strive to achieve at least a modicum of racial diversity. The question, again, is: How will this diversity be managed? Part of the answer has to do with assimilation, an ideological technology for constructing race and a central theme in CRT; and part of the answer has to do with efficiency, an ideological technology for creating incentives and a central theme in L&E. Both ideas - assimilation and efficiency - combine to tell a story about workplace discrimination that derives from what we call the homogeneity incentive. In sum, in order to increase efficiency, employers have incentives to screen prospective employees for homogeneity, and, in order to counter racial stereotypes, nonwhite employees have incentives to demonstrate a willingness and capacity to assimilate. In this sense, the modern workplace discrimination problem may be more about employers requiring people of color to demonstrate racial palatability than about employers totally excluding people of color for the workplace. We discuss whether and to what extent anti-discrimination law can ameliorate this problem

The Context of Comprehension

We enter the teachers\u27 lounge at Woodmere School, where Mrs. Stephens and Ms. Kelly are asking Mrs. Forester, the reading teacher, for advice in developing an effective program in reading comprehension. Mrs. Stephens describes the comprehension ability of each of her students. She is confident that she accurately diagnosed her students as either good comprehenders or poor comprehenders. To do so she administered a test and interpreted the results. Ms. Kelly administered the same test but she is not as comfortable as her colleague in categorizing her readers\u27 abilities

An Analysis of Published Informal Reading Inventories

Believing that IRIs have genuine value in a comprehensive diagnostic program if used properly, we decided it would be useful to examine a number of the commercially prepared IRIs currently available for the purpose of comparing them and describing their unique features for teachers

Active Flow Control at Low Reynolds Numbers on a NACA 0015 Airfoil

Results from a low Reynolds number wind tunnel experiment on a NACA 0015 airfoil with a 30% chord trailing edge flap tested at deflection angles of 0, 20, and 40 are presented and discussed. Zero net mass flux periodic excitation was applied at the ap shoulder to control flow separation for flap deflections larger than 0. The primary objective of the experiment was to compare force and moment data obtained from integrating surface pressures to data obtained from a 5-component strain-gage balance in preparation for additional three-dimensional testing of the model. To achieve this objective, active flow control is applied at an angle of attack of 6 where published results indicate that oscillatory momentum coefficients exceeding 1% are required to delay separation. Periodic excitation with an oscillatory momentum coefficient of 1.5% and a reduced frequency of 0.71 caused a significant delay of separation on the airfoil with a flap deflection of 20. Higher momentum coefficients at the same reduced frequency were required to achieve a similar level of flow attachment on the airfoil with a flap deflection of 40. There was a favorable comparison between the balance and integrated pressure force and moment results
