This essay uses the reprocessing of the "Luis Alberto Sánchez papers," the collection of a prominent Peruvian politician and author housed at Penn State University, to argue that ethical and reparative processing needs should be prioritized within an archives' overall extensible processing program. The author explores the tension between two differing threads within the archival literature of: (1) using minimal or extensible processing practices to efficiently process backlogs; and (2) of acknowledging the power of archivists in shaping the historical record and their ethical responsibilities towards communities represented within their collections. This essay argues that archivists should prioritize collections where archival practices have perpetuated in obfuscating or marginalizing the records of traditionally underrepresented communities. It also argues that prioritizing this work capitalizes on the inherent flexibility within an extensible processing framework.

This paper presents a case study of how librarians can situate themselves as pedagogical partners by bringing their unique information literacy perspective and expertise to the programmatic assessment process. This report resulted from the Thun Library and the Penn State Berks Composition Program's collaboration to assess the institution's first-year composition (FYC) course. From previous programmatic assessments of their students' work, the faculty knew that students struggled with source use in their rhetoric but found it difficult to pinpoint students' exact source issues. By adapting a rubric theoretically-grounded in the ACRL "Framework" to deconstruct the concept of source use into four categories, librarians developed a rubric that illuminated source engagement problems on a more granular level than the programmatic assessments conducted without librarian involvement, leading to specific suggestions for addressing issues with student source engagement

The first PA Forward Information Literacy Summit was held in State College at the Pennsylvania State University, University Park campus, on Wednesday, July 24, 2013. This summit brought together K-12 and academic librarians from Pennsylvania to discuss current issues in information literacy. This text is a transcript of a discussion between Ellysa Cahoy, past chair of the of the ACRL Information Literacy Competency Standards Committee, and the ACRL Information Literacy Competency Standards Review Task Force, and Craig Gibson and Trudi Jacobson who are currently co-chairs of the ACRL Information Literacy Standards Revision Task Force. This Revision Task Force is charged with reviewing and revising the current ACRL Information Literacy Competency Standards for Higher Education, that were originally adopted by ACRL in 2000. This discussion was about the process by which the Standards came to be under review, some of the issues involved in the review, and the time line for the review and librarian feedback and comment on the process. The PowerPoint presentation which accompanied this discussion, as well as other documents mentioned during the presentation are attached to this transcript as supplemental files.

As cigarette smoking expanded dramatically during the early twentieth century, it brought more and more workers into conflict with the policies and demands of the manufacturers who employed them. As this paper shows, addiction to nicotine ignited daily struggles over workers’ shopfloor rights and the ability of employers to set rules, establish discipline, and monitor behavior. A specific set of records from the archives of the Hammermill Paper Company, a paper manufacturer once based in Erie, Pennsylvania, provide a unique opportunity to explore the impact of cigarette consumption on labor relations during the era of mass production, as two nosy factory spies probed and documented worker actions and attitudes in the summer of 1915. As a result of their intelligence gathering, the spies discovered a factory-wide work culture rooted in the addictive pleasure of cigarette smoke. This discovery worried them. Worker-smokers needed to dampen their hunger for nicotine with frequent, and often clandestine, breaks from work, typically in defiance of “no-smoking” rules, employer designations for the uses of factory space, and bosses’ demands for continuous production. Highlighting the intersections of the histories of labor, smoking, and addiction, this paper argues that cigarettes were a key battleground in workers’ and managers’ intensifying struggles over who really controlled the industrial shopfloor during the early 1900s.

The article focuses on the issuance of paper money by Pennsylvania when it was an English Colony. Pennsylvania was successful at issuing paper money with a minimal effect on prices to an extent that it is sometimes said to violate the classical quantity theory of money. The paper contends that new paper issues of money were absorbed without inflation because they encouraged more transactions to be made using money, due to it being more efficient for transactions than barter or bookkeeping. It tries to explain fixed rates in colonial Pennsylvania despite the lack of specie by considering the model of economists Thomas J. Sargent and Neil Wallace that money issues, if backed by "real bills," are not necessarily inflationary.

Purpose: The purpose of this paper is to examine existing learning innovation systems and propose a systematic methodology of delivering educational innovations in the right amount, in the right place and at the right time. Design/methodology/approach: Higher education is not effectively incorporating new discoveries in cognitive science and human learning into effective teaching strategies. In this paper, the authors explore the various impediments to change. To partially overcome these barriers, Drexel University, in collaboration with Untra Academic Management Solutions, LLC, has embarked on the development of a knowledge management system to assist instructors in obtaining, implementing, evaluating and disseminating new educational innovations. The system as envisioned would be capable of adapting to various educational environments and evolving with changes in curricula, faculty expectations, learning outcomes and student characteristics. Findings: The SocraticNet as a learning environment is stimulated, based on Socratic inquiry among teachers and learners. It is an interactive social network system utilising Web 2.0-based emerging technologies fostering communication and sharing among faculty, students and others (e.g. librarians) engaged in a particular course or other educational experience. Students learn by sharing what they know, by asking questions, judging and evaluating the retrieved information, and using this information efficiently in completing their assignments or research papers. This approach results in multidimensional information flow: instructor to instructor, instructor to student, student to instructor, student to student: which adds a new richness to the interactions between faculty and students providing the framework for a true learning community. Research limitations/implications: The present work has been conducted at one institution. This can be extended to include more institutions and tried with different disciplines. There are implications for changes in relation to teaching and learning approached adopted in higher education and also for development of technology tailored to address issues emanating from the scenario. Practical implications: The research work presented has the potential to stimulate debate to further develop and refine thinking on the role and use of technology directed at improving teaching and learning in higher education. Originality/value: This paper examines learning and teaching styles in higher education taking cognizance of conditions and factors impeding new innovations in practice. Details discussions are presented and unique suggestions are made.

Objectives: The objectives of this paper is to conduct a bibliometric analysis to examine the research status and development trend of anterior cruciate ligament injury and reconstruction in children and adolescents over the past 20 years. Design: Descriptive Research. Methods: This study obtained information regarding studies on Anterior Cruciate Ligament Reconstruction in Children and Adolescents from the Web of Science Core Collection database. Visual and bibliometric analysis were conducted using VOSviewer, Origin 2022, Pajek64 5.18and Excel 2019. These analytic tools facilitated the analysis of various aspects, including countries/regions, institutions, authors, journals and keywords related to the research. Results: From 2003 to 2023, a total of 1328 articles were retrieved in WOS, and 637 articles were selected by two authors. The most productive institutions are Childrens Hosp Philadelphia, Kocher, ms. Their articles have the highest number of publications and citations. The American journal of sports medicine is the most frequently cited journal for articles on anterior cruciate ligament reconstruction in children and adolescents. The most common keywords used in these articles were "anterior cruciate ligament reconstruction", "injury, children, adolescent", and "skeletally immature patients". Conclusions: This study provides valuable insights into the research focus of anterior cruciate ligament reconstruction in children and adolescents. In recent years, there has been significant attention paid to areas of "the return to sport, re-repture rate and functional recovery after anterior cruciate ligament reconstruction" in this specific population. These aspects have emerged as key directions for future research in this field. [ABSTRACT FROM AUTHOR]

Local control of schooling has been considered a defining feature of the American school system; however, in the past several decades of public schooling has also increasingly been subject to the influence of extralocal institutional mandates that encourage curricular and organizational standardization. We conducted a content analysis of 480 school district mission statements from Pennsylvania to understand the relationships between school and place and the locally articulated purposes of schooling. Strikingly uniform use of language and themes across multiple district contexts suggests that (a) district mission statements may not be representative of locally articulated visions of schooling and (b) the influences of local context may be superseded by broader institutional discourses regarding the purposes of education and schooling.

Wireless charging schemes aim to counter some drawbacks of electric vehicles' wired charging, such as the fact that it does not encourage mobility, leads to safety issues regarding high voltage cables, power adapters high cost, and has more battery waste by companies. In this paper, a comparative study of wireless power transfer multiple coil geometries is performed to analyze the efficiency, coupling coefficient, mutual inductance, and magnetic flux density production for each geometry. Results show that coil geometry, current excitation, and shielding techniques within the Wireless Electric Vehicle Charging (WEVC) system substantially influence magnetic flux leakage. In addition, the paper proposes an analytical framework for a WEVC scheme via electromagnetic resonance coupling. Safety considerations of the WEVC system, including the effects on humans, are investigated in several scenarios based on the relative location of the human while EV charging is conducted as the leading paper's goal. The exposure measurements are performed across various radial distances from the coils using 3-D FEA ANSYS Maxwell Software (American technology company, Pennsylvania, United States). The analysis shows that WEVC systems can achieve high power transfer, resulting in increased magnetic flux leakage around the coils. The safe distance for humans and animals during the charging sequence is attained from research results. For instance, in the 120 mm spiral coil, 120 mm square coil, and 600 mm spiral coil operating at 1 A, excitation, the SAR levels are under the threshold of 700 mm away from the coils. For the 600 mm spiral coil excited at 8 A, the SAR levels fall under the threshold at 900 mm away from the coils. When shielding is utilized, the safe distance is improved by up to 350 mm. Considering the regulations of the Non-Ionizing Radiation Protection (ICNIRP) standards, 600 mm is a safe distance away from the coils, and, vertically, anywhere past 300 mm is safe for humans.

In addition, a study is under way concerning causes of rejections by union rank and file of contracts negotiated by representatives.

With the development of artificial intelligence technology, machine learning-based production forecasting models can achieve the rapid prediction and analysis of production. However, these models need to be built on a large dataset, and having only a small amount of data may result in a decrease in prediction accuracy. Therefore, this paper proposes a transfer learning prediction method based on the hierarchical interpolation model. It uses data from over 2000 shale gas wells in 22 blocks of the Marcellus Shale formation in Pennsylvania to train the transfer learning model. The knowledge obtained from blocks with sufficient sample data is transferred and applied to adjacent blocks with limited sample data. Compared to classical production decline models and mainstream time-series prediction models, the proposed method can achieve an accurate production decline trend prediction in blocks with limited sample data, providing new ideas and methods for studying the declining production trends in shale gas.

Because dairies across the United States have rapidly adopted breeding to beef breed sires, the use of beef semen has increased dramatically in recent years. The objective of this survey was to gather information about the use of beef semen by dairy producers in the Northeast United States to generate beef × dairy cattle for beef markets. The survey was conducted using the services of the Center for Survey Research at the Pennsylvania State University—Harrisburg campus. Respondents had two options for returning their responses: 1) mail the paper survey to CSR in the postage-paid business-reply envelope included in the mailing, or 2) complete the survey online via an open-access web survey link. A total of 669 surveys were received and a final number of 617 surveys were included in the responses based on completeness and validity of the responses. Because of the broad electronic distribution, a true response rate cannot be calculated. Of these, 463 (75.0%) were completed via returned paper survey, and 154 (25.0%) were completed via web, between November 9, 2021 and February 16, 2022. Of the 617 respondents, 539 were from Pennsylvania. Due to the large variations in returned survey copies by state, results are reported without state separation. Across all respondents, 69.7% reported milking 100 or fewer cows and over 90% of collected responses reported Holsteins as the predominant dairy breed in the Northeast. Only 18.8% of the respondents did not currently, nor plan to, breed with beef semen. Deciding which beef bulls to use on Northeast dairy farms was primarily based on the recommendation of the semen sales representative (54.5%) and the price of the semen purchased (42.3%). In addition, 89.7% of respondents cited using Angus genetics in their beef bull selections. However, there was no difference in reported profitability of crossbreeding between respondents who indicated using other beef breeds vs. those who indicated just using Angus (P ≥ 0.19). In conclusion, using beef sires on dairy females, regardless of the breed of beef sire, adds value to the resulting progeny from dairy farms in the Northeast. [ABSTRACT FROM AUTHOR]

The article presents summaries of papers delivered at the 125th annual meeting of the American Statistical Association. The meeting took place on September 1965 in Philadelphia, Pennsylvania. In the paper "On the Construction of Stochastic Working Life Tables," by Haskel Benishay, stochastic working life tables are constructed and evaluated. The essence of the construction of stochastic rather than the traditionally deterministic working life tables is in the utilization of the realistic assumptions that the number of births, the number of entries into the labor force, the duration of life, and the duration of working life, are random variables. The end result is a working life table with a double entry in each cell rather than the single traditional one. The implications of this approach for the evaluation of fluctuations in various subcomponents of the labor force are evaluated. Another paper "Measuring Elasticities of Air Travel," by Samuel L. Brown, summarizes research on the response of demand for air travel to differences of fares, incomes, and elapsed travel time. There are three kinds of studies. Multiple regression studies of time series of air traffic, fares and income in the national domestic market yield short-period fare elasticities and income-elasticities. A quarterly first-difference model stands well the usual statistical tests.

Prostate cancer is the most common cancer after non-melanoma skin cancer and the second leading cause of cancer deaths in US men. Its incidence and mortality rates vary substantially across geographical regions and over time, with large disparities by race, geographic regions (i.e., Appalachia), among others. The widely used Cox proportional hazards model is usually not applicable in such scenarios owing to the violation of the proportional hazards assumption. In this paper, we fit Bayesian accelerated failure time models for the analysis of prostate cancer survival and take dependent spatial structures and temporal information into account by incorporating random effects with multivariate conditional autoregressive priors. In particular, we relax the proportional hazards assumption, consider flexible frailty structures in space and time, and also explore strategies for handling the temporal variable. The parameter estimation and inference are based on a Monte Carlo Markov chain technique under a Bayesian framework. The deviance information criterion is used to check goodness of fit and to select the best candidate model. Extensive simulations are performed to examine and compare the performances of models in different contexts. Finally, we illustrate our approach by using the 2004-2014 Pennsylvania Prostate Cancer Registry data to explore spatial-temporal heterogeneity in overall survival and identify significant risk factors.

Background: Recruiting large cohorts efficiently can speed the translation of findings into care across a range of scientific disciplines and medical specialties. Recruitment can be hampered by factors such as financial barriers, logistical concerns, and lack of resources for patients and clinicians. These and other challenges can lead to underrepresentation in groups such as rural residents and racial and ethnic minorities. Here we discuss the implementation of various recruitment strategies for enrolling participants into a large, prospective cohort study, assessing the need for adaptations and making them in real-time, while maintaining high adherence to the protocol and high participant satisfaction. Methods: While conducting a large, prospective trial of a multi-cancer early detection blood test at Geisinger, an integrated health system in central Pennsylvania, we monitored recruitment progress, adherence to the protocol, and participants' satisfaction. Tracking mechanisms such as paper records, electronic health records, research databases, dashboards, and electronic files were utilized to measure each outcome. We then reviewed study procedures and timelines to list the implementation strategies that were used to address barriers to recruitment, protocol adherence and participant satisfaction. Results: Adaptations to methods that contributed to achieving the enrollment goal included offering multiple recruitment options, adopting group consenting, improving visit convenience, increasing the use of electronic capture and the tracking of data and source documents, staffing optimization via leveraging resources external to the study team when appropriate, and integrating the disclosure of study results into routine clinical care without adding unfunded work for clinicians. We maintained high protocol adherence and positive participant experience as exhibited by a very low rate of protocol deviations and participant complaints. Conclusion: Recruiting rapidly for large studies – and thereby facilitating clinical translation – requires a nimble, creative approach that marshals available resources and changes course according to data. Planning a rigorous assessment of a study's implementation outcomes prior to study recruitment can further ground study adaptations and facilitate translation into practice. This can be accomplished by proactively and continuously assessing and revising implementation strategies. [ABSTRACT FROM AUTHOR]

Over the last few years, much attention has been focused on the nationwide teacher shortage. As teachers begin to retire in record numbers, and the number of students entering teacher education majors continues to decline, concern around the teacher shortage heightens (US Dept. of Ed., 2016). The numbers are even more dire when looking at Teachers of Color entering the profession (US Dept. of Ed., 2016). To address this TOC shortage, Pennsylvania’s Department of Education called for Institutions of Higher Education to create programs aimed at attracting and retaining students of color in their teacher education programs. The Aspiring to Educate (A2E) program was Pennsylvania’s intentional attempt to diversify the teacher workforce. This paper describes the work of three Black educators, as they examine their positionality and work independently and collectively to answer PA’s call to action through the implementation of start-up Grow Your Own programs.

This paper examines ways in which human values toward surface water, especially large rivers, are relevant to land-use decisions in the watersheds. The study's focus is the symbolic riverscape constructed by residents local to the Susquehanna River at the confluence of its branches in central Pennsylvania. The main analytical tool is the cultural landscape, a conceptualization of the ways in which alteration of the physical world is the product of human value systems. The paper traces the symbolic weights apparent in discourses about the Susquehanna River with regard to environmental use and abuse in the watershed, through qualitative analysis of public expressions of meaning and valuation. The conclusions emphasize an evolution of the meaning of the river toward a central role as an integral and intricate part of the human experience on the landscape, rather than its earlier role as one functional part of the economic system. Land-use actions consonant with that new value are now favored. This work is offered to suggest that land system science, which is highly effective in understanding altered natural systems and their consequences, can benefit from a fuller engagement with more-intimate human aspects of landscape such as symbols, meaning, and narrative.

The article presents information on the annual meeting of the society of scientific study of religion at Vista International Hotel Pittsburgh, Pennsylvania. This year's theme of religious marginality encourages participants to go beyond core beliefs and practices of members of mainline churches to the expressions of interest or disinterest in religion that are less common religious experience, mixed intermarriage, unclear interpreting "don't know" responses to questions on belief, nonestablishment (religion among street people), or rejections of religion atheism and apostasy. List of topics related to this year's theme would include, denominational switching and conversion, sources of membership change in the mainline churches, apostates and returnees, new nones (apostates) vs. stable nones with no prior ties, inter-religious marriage and religion of children, divorce, religious socialization of children, religiosity and the life cycle, Inter-racial marriage and religion and the Black Church.

He would like to encourage people to know on the records at the National Archives.

Advance directives are intended to extend patient autonomy by enabling patients to prospectively direct the care of their future incapacitated selves. There has been much discussion about issues such as whether the future incompetent self is identical to the agent who issues the advance directive or whether advance directives can legitimately secure patient autonomy. However, there is another important question to ask: to what extent and in what conditions is it ethically appropriate for one to limit the liberty or agency of one's future incompetent self by issuing an advance directive? In this paper, I use a virtue‐ethical approach to explore this question, focusing on the case of an advance directive for the future self with moderate dementia. First, I examine virtuous attitudes with regard to autonomy and argue that one can manifest vices or ethically undesirable character traits in trying to intervene in the future self's life. In particular, I argue that this case can manifest vices such as disdainfulness, intellectual arrogance, and self‐dictatorship, which is the vice of trying to control one's life to an excessive degree, and that a self‐dictator fails to give due moral consideration to the future self's liberty or agency. I then introduce the Daoist idea of wu‐wei, which recommends embracement of what happens in one's life, as one of the possible remedies for the overemphasis on the value of autonomy and control.

Political redistricting is the redrawing of electoral district boundaries. It is normally undertaken to reflect population changes. The process can be abused, in what is called gerrymandering, to favor one party or interest group over another, resulting thereby in broadly undemocratic outcomes that misrepresent the views of the voters. Gerrymandering is especially vexing in the United States. This paper introduces an algorithm, with an implementation, for creating districting plans (whether for political redistricting or for other districting applications). The algorithm, Seed-Fill-Shift-Repair (SFSR), is demonstrated for Congressional redistricting in American states. SFSR is able to create thousands of valid redistricting plans, which may then be used as points of departure for public deliberation regarding how best to redistrict a given polity. The main objectives of this paper are: (i) to present SFSR in a broadly accessible form, including code that implements it and test data, so that it may be used for both civic deliberations by the public and for research purposes. (ii) to make the case for what SFSR essays to do, which is to approach redistricting, and districting generally, from a constraint satisfaction perspective and from the perspective of producing a plurality of feasible solutions that may then serve in subsequent deliberations. To further these goals, we make the code publicly available. The paper presents, for illustration purposes, a corpus of 11,206 valid redistricting plans for the Commonwealth of Pennsylvania (produced by SFSR), using the 2017 American Community Survey, along with descriptive statistics. Also, the paper presents 1,000 plans for each of the states of Arizona, Michigan, North Carolina, Pennsylvania, and Wisconsin, using the 2018 American Community Survey, along with descriptive statistics on these plans and the computations involved in their creation.

The increase in the concentration of geological gas emissions in the atmosphere and particularly the increase of methane is considered by the majority of the scientific community as the main cause of global climate change. The main reasons that place methane at the center of interest, lie in its high global warming potential (GWP) and its lifetime in the atmosphere. Anthropogenic processes, like engineering geology ones, highly affect the daily profile of gasses in the atmosphere. Should direct measures be taken to reduce emissions of methane, immediate global warming mitigation could be achieved. Due to its significance, methane has been monitored by many space missions over the years and as of 2017 by the Sentinel-5P mission. Considering the above, we conclude that monitoring and predicting future methane concentration based on past data is of vital importance for the course of climate change over the next decades. To that end, we introduce a method exploiting state-of-the-art recurrent neural networks (RNNs), which have been proven particularly effective in regression problems, such as time-series forecasting. Aligned with the green artificial intelligence (AI) initiative, the paper at hand investigates the ability of different RNN architectures to predict future methane concentration in the most active regions of Texas, Pennsylvania and West Virginia, by using Sentinel-5P methane data and focusing on computational and complexity efficiency. We conduct several empirical studies and utilize the obtained results to conclude the most effective architecture for the specific use case, establishing a competitive prediction performance that reaches up to a 0.7578 mean squared error on the evaluation set. Yet, taking into consideration the overall efficiency of the investigated models, we conclude that the exploitation of RNN architectures with less number of layers and a restricted number of units, i.e., one recurrent layer with 8 neurons, is able to better compensate for competitive prediction performance, meanwhile sustaining lower computational complexity and execution time. Finally, we compare RNN models against deep neural networks along with the well-established support vector regression, clearly highlighting the supremacy of the recurrent ones, as well as discuss future extensions of the introduced work.

Ecological data are being collected at a large scale from a multitude of different sources, each with their own sampling protocols and assumptions. As a result, the integration of disparate datasets is a rapidly growing area in quantitative ecology, and is subsequently becoming a major asset in understanding the shifts and trends in species' distributions.However, the tools and software available to construct statistical models to integrate these disparate datasets into a unified framework is lacking. This has made these methods inaccessible to general practitioners and has stagnated the growth of data integration in more applied settings.We therefore present PointedSDMs: an easy to use R package used to construct integrated species distribution models. It provides functions to easily format the data, fit the models in a computationally efficient way and presents the output in a format that is convenient for additional work.This paper illustrates the different uses and functions available in the package, which are designed to simplify the modelling of integrated models. A case study using the package is also presented: combining three datasets coming from different sampling protocols, all containing records of Setophaga caerulescens across Pennsylvania state.

The theory and empirical analysis of the public provision of private goods have primarily considered the provision of education and healthcare. In this paper, we extend the application of the theories presented in Epple and Romano (1996a, 1996b) to the provision of a more private good—a golf course. While there may be some public social benefits of recreation including golf, for the most part, golf is a private good. We analyze golf course ownership in Pennsylvania, a state with a diversity of municipalities. Our main findings support the ends-against-the-middle hypothesis in which municipalities with a majority of low-income voters and high-income voters are less likely to own a municipal golf course. Municipalities with a majority of middle-income voters are more likely to own a municipal golf course. [ABSTRACT FROM AUTHOR]

Educators in computing-related degree programs (CS, IT, and IS) may need to regularly update their courses and programs to keep them relevant to the in-demand industry skills. Continuous and rapid changes require regular revisions in computing programs and curricula. Courses that teach computer programming, especially introductory programming language courses, need to be updated to reflect the languages in demand in the industry. Not being current with curriculum updates for these courses will likely put the programs behind due to outdated curricula. This is the case for the computer science (CS) program at a university located in Western Pennsylvania. The syllabi for the programming courses have not been updated for some time. In the process of updating the programming courses, an important question to address is the critical factors to consider when updating the syllabi of the programming course(s). This paper reviews the relevant literature and discusses the factors to be taken into consideration when updating computer programming courses. A set of recommendations for course updates are provided toward the end of the paper. [ABSTRACT FROM AUTHOR]

Simple Summary: Steel production emits manganese and other heavy metals into the environment, where these byproducts can lead to health problems in humans and other animals. Birds have historically been used to detect harmful chemicals in the air, and in this paper, we show that this role continues into the present day. Feathers of a small terrestrial songbird, the Tufted Titmouse, were collected from live birds captured both near (0.3 km) and far (4.0 km) from steel production facilities in western Pennsylvania, USA. Tail feathers from birds living near the facilities had significantly higher amounts of manganese embedded in their structure compared to the feathers of birds living farther away. This shows that manganese is present in the environment, is localized at industrial sites, is encountered by birds, and is sequestered in their tissues. Animals could suffer ill health if exposures are high enough. Feather data cannot be used to assess the magnitude of this health risk since metals laid down within feathers are no longer circulating in the birds' bodies. However, our data do suggest that the environmental monitoring of manganese should continue, as inadvertent exposure is still occurring. Human industry and land use has led to the anthropogenic release of manganese (Mn) into the air and soil near manufacturing centers. Overexposure to Mn can cause considerable health problems in birds. We studied whether the concentration of Mn in bird feathers correlates with the distance to point sources of Mn air emissions. Feathers were collected from Tufted Titmice (Baeolophus bicolor) at two sites in western Pennsylvania, USA. One site was in proximity (0.3 km) to a steel plant with documented Mn releases, and the other site was in a different town about 4.0 km away from other steel plants with documented Mn releases. Using the microwave plasma–atomic emission spectrometer (MP–AES), we found that tail feathers collected from nearest to a steel plant had a significantly higher concentration of Mn compared to the samples from the site further from the emission source. A body mass index was calculated for each set of birds; however, the indices did not vary significantly. This is the first published study of Mn sequestration in Tufted Titmouse feathers. This study develops our general understanding of the potential use of bird feathers as non-invasive bioindicators of environmental metal exposure. [ABSTRACT FROM AUTHOR]

The U.S. K–12 public education system has been notoriously hard to improve. Some argue new education technologies (EdTech) can help transform schools for the better. Yet, as large-scale policy reforms have had only limited success, it seems unlikely that small changes from EdTech could have any measurable impact. In this paper, we study DonorsChoose, a nonprofit that operates a teacher crowdfunding platform. We ask whether DonorsChoose improves educational outcomes, specifically at low-income schools. Combining DonorsChoose data with data on student test scores in Pennsylvania from 2012–2013 to 2017–2018, we find that an increase in the number of DonorsChoose projects funded at a school leads to higher student performance, after controlling for selection biases. For a school with zero funded projects, one funded project—of about $400 in value—translates to between two to nine more students scoring basic and above in all subjects in high school and science and language arts in primary and middle school. We find this effect is driven mostly by low-income schools, indicating funded projects help close the gap in educational outcomes between students at low- versus high-income schools. Based on a textual analysis of 20,000 statements from all funded teachers describing how project resources are used, we find two channels of improvement most effective in the lowest income schools. We demonstrate that, although DonorsChoose projects are small, they improve outcomes and reduce inequality because they come directly from frontline workers—teachers—who know most intimately the obstacles their students face and how to help.

Increasing precipitation variability has led to growing concerns about the risk of flood in many parts of the U.S. and worldwide. This study adopts a spatial regression analysis framework based on floodplain boundary discontinuities to control for unobserved spatial heterogeneities in flood risk assessment. The empirical strategy combines spatial matching with the regression discontinuity design. Using parcel-level data from Juniata County, Pennsylvania, we find an over six percent property value reduction due to additional one-standard-deviation flood exposure as defined by the percentage of property area inside the flood zone. Specifically, given that the study region's average single-family residential housing price is $114,684 (in 2015 USD), the estimated flood risk impact is $7056 (in 2015 USD, or 6.15%) for a one-standard-deviation increase in flood exposure. The estimate (for a rural housing market) is of a similar magnitude to several recent estimates from urban and suburban housing markets. This paper contributes to the literature as one of the first quantitative studies of flood risk impacts on rural housing markets. [ABSTRACT FROM AUTHOR]

The United States along with the rest of the world has experienced an unprecedented disruption in daily life due to the COVID-19 pandemic. Almost everyone has experienced some sort of stay at home order resulting in an economic catastrophe greater than the Great Recession of 2008 and on par with the Great Depression almost a century ago. Educational institutions at both the K-12 and post-secondary levels have not been immune from the shutdown, with many schools closed from mid-March through the end of the 2020 school year. Many schools moved classes to remote, distance delivery platforms. Career and Technical Education (CTE) teachers were tasked with creative engaging learning activities online for curricula which is taught in a hands-on contextual learning environment. This paper will present preliminary results from research conducted by a collaborative group of nine researchers from across the United States with collectively over 200 years of career and technical education experience. The conceptual framework used for this study was Danielson's Framework for Teaching and Enhancing Professional Practice and Foundations of Career and Technical Education including Constructivism. 3,267 participants representing all 50 states responded to the 37-item survey. The research objectives included description of participants and identified challenges to planning and delivery of CTE content when schools were closed, and instruction was moved to remote/distance/online platforms. Participants ranked their challenges as instructors and their perceptions of challenges that were experienced by their students. CTE teachers ranked replicating classroom or lab environments online and lack of experience teaching online as their biggest challenges. The perceptions of the participants concerning challenges for their students included motivation to guide and manage their own learning and students' access to reliable internet connection. The emergence and prevalence of the COVID-19 pandemic added a layer of complexity to educational practice that was not foreseen and for which no intentional preparation had occurred. Understanding how CTE teachers and instructors responded to this call, and the challenges they and their students encountered, is important to efforts to improve practice in the future and to be in a better position should another crisis occur that forces learning to be delivered in alternative formats from that of the traditional face-to-face classroom.

This comparative case study examines the policies of two new immigrant destinations in the United States and Canada that in the past 20 years experienced a rapid influx of immigrants. Using an integrated framework of policy design theory and the context of reception, this paper analyzes the framing of immigrant students in the state, district, and school-level policies. Interviews with immigrant students in these communities show how these policies shaped their schooling experiences and communicated important messages to them about their role in their new communities, thus shaping their political identities. The findings highlight the important interplay of these different policymakers in shaping the contexts of receptions students encountered. The paper concludes by discussing educators' role in working to craft more equitable policies.

The intersection in 2020 of the new COVID-19 pandemic with the ongoing pandemic of anti-black racism exacerbated existing injustices as well as caused and revealed new inequities in US higher education. Because inequities in assessment in particular were intensified by these twin pandemics, faculty at several US colleges revised assessment approaches as part of their pedagogical partnership work over the last year. This paper describes the one-on-one, semester-long, pedagogical partnerships these faculty undertook with undergraduates not enrolled in the faculty members' courses. It reviews the commitments of such partnership work to equity and justice, offers examples of how four faculty-student pairs across the disciplines at three US colleges revised their approaches to assessment, and analyzes how these examples work toward equity and justice. The paper concludes with a discussion of the implications of such work not only at the intersection of twin pandemics but under all circumstances.

Work zone safety is a high priority for transportation agencies across the United States. Enforcing speed compliance in work zones is an important factor for reducing the frequency and severity of crashes. This paper uses connected vehicle trajectory data to evaluate the impact of automated work zone speed enforcement on three work zones in Pennsylvania and two work zones in Indiana. Analysis was conducted on more than 300 million datapoints from over 71 billion records between April and August 2021. Speed distribution and speed compliance studies with and without automated enforcement were conducted along every tenth of a mile, and the results found that overall speed compliance inside the work zones increased with the presence of enforcement. In the three Pennsylvania work zones analyzed, the proportions of vehicles travelling within the allowable 11 mph tolerance were 63%, 75% and 84%. In contrast, in Indiana, a state with no automated enforcement, the proportions of vehicles travelling within the same 11 mph tolerance were found to be 25% and 50%. Shorter work zones (less than 3 miles) were associated with better compliance than longer work zones. Spatial analysis also found that speeds rebounded within 1–2 miles after leaving the enforcement location. [ABSTRACT FROM AUTHOR]

ePortfolios have been used in many disciplines for different purposes. In the following paper, I describe how I created and used an eportfolio as my tenure file over a five-year period. As the first tenure-track faculty member at Delaware County Community College to attain tenure through the use of an online tenure portfolio, the tenure eportfolio played many roles including as a summative, reflective, and showcase tool. Using an eportfolio for tenure promotion has become increasingly popular at my institution which now has an institutional eportfolio software package that all new tenure-track faculty use to create their online tenure files. This paper also discusses the advantages and disadvantages of using a prescribed eportfolio software package in creating tenure eportfolios. [ABSTRACT FROM AUTHOR]

This paper employs multilevel factor modelling techniques to unravel systematic unobserved determinants of the intraday and interzonal price curve dynamics for the Pennsylvania-New Jersey-Maryland (PJM) interconnection. These techniques make an explicit separation of global drivers from region-specific common factors, thereby facilitating the identification of the actual sources of co-variability. Our empirical findings confirm the hypothesis that the common unobserved determinants of power prices in the PJM interconnection obey a block structure, some of which affect different segments of our panel. We argue that a multilevel factor approach offers a more systematic and transparent representation of intertemporal and cross-sectional patterns in PJM electricity prices compared to alternative brute-force VARMAX parametrizations and the single-level factor models, which are often put forward in the literature as viable modelling alternatives.
