No full textWhittier House scrapbooks document Whittier House programs, events, and anniversary celebrations through newspaper clippings, lecture fliers, newsletters, event programs, and ticket stubs. Newspaper clippings are primarily from the Jersey Journal. There is also Whittier House fundraising materials, including pamphlets, appeal letters, brochures, and postcards. The Whittier House Social Settlement, the first settlement house in New Jersey, was established in Jersey City, N.J. (Hudson County) in 1894. Founded by Cornelia Foster Bradford, who would remain with the organization as headworker until 1926, Whittier House was based on the settlement house, Toynbee Hall, in England. Whittier House provided various recreational and educational programs, along with much needed social services, for the immigrant populations of Jersey City. Many of these successful services were used as models for large-scale social reform movements through the state. In 1935, the Whittier House was taken over by the Boys' Club of Jersey City
Non-Scientist Sources Lend Balance, but Create Bias

Promoting the Study of Natural Resources in K-12 Classrooms: Developing Active Professional Learning Communities for Science Educators On-Line
No full textLaboratory Earth originated as a series of graduate courses offered to K-12 teachers by the School of Natural Resources at the University of Nebraska-Lincoln. The scientific content of the courses is congruent with topics identified in the National Science Education Standards and is designed to meet a variety of learning styles and appeal to teachers’ motivation to learn the content and improve their teaching. These graduate-level courses consist of four modules , are taught entirely on-line, and are part of a 36 credit hour graduate program, Science for Educators specialization in a Masters of Applied Science program at UNL. The Laboratory Earth program has grown in scope--from an initial three to six Lab Earth courses, as well as in sophistication of delivery. Course activities now include group projects interacting with on-line climate models and GIS software, as well as synchronous virtual chats and lectures using no-cost meeting software such as EVO and Join.me. Web 2.0 technologies sought out by the participants themselves are now complementing the Content Management System hosting the course at the university. Pre- and post-course surveys indicated significant increases in teachers‘ (n=51) content knowledge, science teaching efficacy beliefs (STEBI- A), sense of community within the course (LEO) and science teaching enjoyment (STES). Qualitative data indicated teachers valued the cohort system, content aligned to teaching needs, and the instructor’s response to requested feedback. Participants in the Lab Earth program find on-line learning an attractive professional development option. Throughout the Great Plains and western United States, many rural teachers live as far as 200 miles from an institution of higher education. For those teachers, participation in on-line courses provides an opportunity to be part of a vibrant and active professional learning community, where they can accumulate graduate credit while developing expertise and lesson plans that they can use in their own classroom. We have teachers who continue to take classes after graduation because of the value they see in continuing professional development within a community of dedicated professionals, developing and sharing lesson plans and inquiry-based activities, and tackling challenges they face in their classrooms together
Use of Fourier-Transform Infrared Spectroscopy for the Diagnosis of Failure of Transfer of Passive Immunity and Measurement of Immunoglobulin Concentrations in Horses
No full textBackground: The economic, accurate, and rapid screening of foals for failure of transfer of passive immunity (FPT) is essential to ensure timely intervention. Hypothesis: Infrared (IR) spectroscopy of foal sera and pattern recognition may be used to diagnose FPT and quantify serum IgG. Samples: Sera from 194 foals (24–72 hours) with serum immunoglobulin G (IgG) concentrations determined previously by radial immunodiffusion assay (RID) were used. Methods: IR spectra were recorded for the serum samples, and the data were randomly divided into training and independent test sets, each containing both FPT-positive (IgG <400 mg/dL) and non-FPT samples. A genetic optimal region selection algorithm and linear discriminant analysis were used to partition the training spectra, and the resulting classifier was then validated by comparing the IR-predicted FPT status for each of the test samples to that provided by the RID IgG assay. A quantitative IR-based assay for IgG was developed using partial least squares (PLS) and validated by testing its ability to predict IgG concentrations. Results: Specificity, sensitivity, and accuracy for the combined data were 92.5, 96.8, and 95.9%, respectively. Corresponding positive (88.1%) and negative predictive (98.0%) values determined a success rate of 95–97% as compared to RID-based IgG concentrations. The IR-based quantitative assay yielded correlation coefficients for IR spectroscopy versus RID-based IgG concentrations of 0.90 and 0.86 for the training and test sets, respectively. Conclusions and Clinical Importance: The overall performance of the IR-based test was similar to that of the colorimetric assay and was superior and more economic than other available tests.Christopher B.

Beyond Data and Learning Outcomes: Understanding the Personal and Social Dimensions of Citizen Science Volunteer Engagement
No full textCitizen science is a term broadly used to describe activities that typically involve the public in the process, methods, and standards of scientific research with the aim of advancing scientific knowledge or application. Engagement in citizen science for project and program volunteers is influenced by much more than an individual’s interest or desire to learn and contribute to scientific research and can be assessed beyond counts and statistics associated with their project role. Opportunities with citizen science have been identified as mechanisms to support the personal development of an individual's science-related identity in addition to their social and cultural identities, especially for participants from communities and backgrounds considered to be nondominant and underrepresented in science, technology, engineering, and mathematics (STEM). Additionally, social aspects of participation in citizen science have been identified, both as indicators of volunteer satisfaction and as contributors to continued project engagement. While previous studies on citizen science and volunteer engagement have acknowledged the lack of demographic diversity in terms of gender, race/ethnicity, education, and socioeconomic status, to date there remains little record of the sexual orientation and/or gender identity of citizen science volunteers. In this study I contribute to efforts to include these aspects of identity by exploring the experiences of LGBTQ+ volunteers in citizen science. This research project incorporated three elements reported in three manuscripts: 1) a survey of citizen science practitioners (N=49) that reveals the extent to and methods by which citizen science projects contribute to the science identity development and community-building of and among their project volunteers. A mixed-methods analysis of data from closed and open response survey items highlights the current methods by which and factors that could be improved related to how citizen science projects promote science identity development and community-building among their volunteers. 2) semi-structured interviews (N=14) conducted with lesbian, gay, bisexual, transgender, and queer (LGBTQ+)-identifying citizen science volunteers to explore the relationships between citizen science volunteers’ science identities and queer, sexual orientation, and/or gender identities. The narratives of LGBTQ+ citizen science volunteers are explored to understand if, how, and to what extent engagement with science as a citizen science volunteer contributes to the development of their science identities in addition to the interplay between their science identities and queer identities, among other aspects of their lives and backgrounds. Finally, 3) based on the semi-structured interviews (N=14) conducted with LGBTQ+-identifying citizen science volunteers, a study to understand how they characterize a sense of community, which includes social interactions and social/community connectedness, within and beyond the context of a group of citizen science volunteers. The experiences and stories of LGBTQ+ citizen science volunteers regarding the degree of social interaction and sense of community among other project volunteers and/or leaders are examined to highlight the importance of community among citizen science volunteers, especially those that identify as LGBTQ+

Emerging low-carbon urban mega-projects
No full textThis is the author accepted manuscript. The final version is available from Springer via the DOI in this recordThis chapter focuses on the recent trend in some geographical locations (particularly China and the United Arab Emirates) towards building large-scale low-carbon city projects. These low-carbon cities are increasingly being described as mega-projects due to their scale and involvement of large-scale experimental approaches to ways of organizing the low-carbon city. The chapter discusses some of the main trends towards the development of low-carbon eco-city projects since 2000, and then introduces the two main low-carbon city mega-projects currently being developed
Which Canadian Seniors Are Below the Low-Income Measure?
No full textAbout 6% of seniors in Canada have family incomes below the Low-Income Measure. (The Low-Income Measure is 50% of the median family income, adjusted for family size, and is a commonly used, if arbitrary, operational definition of relative poverty.) This is a low rate by international standards, in sharp contrast to the high rate in Canada about 35 years ago. It is lower than the comparable rates for the general Canadian population or for families with children and more Canadians leave below-LIM status during their retirement years than enter it. Canadian income tax data show that the remaining 6% are disproportionately immigrant, female, currently unmarried and supporting dependent children (possibly grandchildren). Age does not appear to be of great importance.relative poverty, Canadian income distribution, pension adequacy

A solver for clustered low-rank SDPs arising from multivariate polynomial (matrix) programs
No full textIn this thesis, we give a primal-dual interior point method specialized to clustered low-rank semidefinite programs. We introduce multivariate polynomial matrix programs, and we reduce these to clustered low-rank semidefinite programs. This extends the work of Simmons-Duffin [J. High Energ. Phys. 1506, no. 174 (2015)] from univariate to multivariate polynomial matrix programs, and to more general clustered low-rank semidefinite programs. Clustered low-rank semidefinite programs are programs with low-rank constraint matrices where the positive semidefinite variables are only used within clusters of constraints. The free variables can be used in any constraint, and can be used to connect clusters. The solver uses this structure to speed up the computations in two ways. First, the low rank structure is used to reduce matrix products to products of the form uT M v, where M is a matrix and u and v are vectors, as already suggested by Löfberg and Parrilo in [43rd IEEE CDC (2004)]. Second, an additional block-diagonal structure is introduced due to the clusters. This gives the possibility to do operations such as the Cholesky decomposition block-wise. We apply this to sphere packing and spherical cap packing. For sphere packing, the speed of the solver is compared to the often used arbitrary precision solver SDPA-GMP, showing the theoretical speedup in time complexity. We give a new three-point bound for the maximum density when packing spherical caps of sizes on the unit sphere. https://github.com/nanleij/Clustered-Low-Rank-SDP-solver Repository link Github repository with the Julia code of the solverApplied Mathematics | Optimizatio
