The Pennsylvania Environmental Resource Consortium: A State-Wide Collaborative Network for Sustainable, Outreach, Education, and Action

This paper explores the organizational theory, programs, and concomitant challenges faced by a state-level higher education consortium for sustainability in the United States, the Pennsylvania Environmental Resource Consortium (PERC). We provide insights for other institutions of higher education that may want to form consortia or consider changes to existing consortia. PERC members collaborate to advance sustainability on member campuses, in local communities, and across the Commonwealth. PERC envisions thriving, just communities on a healthy planet, and seeks to inspire higher education communities throughout the Commonwealth to lead transformational sustainability efforts through example, expertise, and collaboration. This chapter provides a brief theoretical background in PERC as a collaborative. It shares history and context for PERC’s mission and activities as well as an overview of its programs. It includes reflections on challenges to collaboration and coordination, including from COVID-19, changing digital technology, disparities among PERC institutions, accelerating sustainability challenges in the Anthropocene, anti-intellectualism and hyperpartisanship in the Commonwealth and the United States, and PERC’s own staffing, volunteerism, participation, and funding challenges. The chapter closes by revisiting the organization’s 2021–2025 Strategic Plan as an invitation to consider how cooperation, coordination, and collaboration among higher education institutions can positively impact sustainability across sectors

Comparison of Langmuir probe and laser Thomson scattering for electron property measurements in magnetron discharges

Electron property measurements made by Langmuir probe and laser Thomson scattering have been compared in weakly magnetized plasma conditions using a planar unbalanced magnetron with the aim of assessing the accuracy of the probe diagnostic. Measurements were performed at several locations within the magnetic field configuration; the magnetic null region (. 1 mT) on the discharge axis and inside the last closed flux surface boundary with fields up to 33 mT. There was good diagnostic agreement during High Power Impulse Magnetron Sputtering (HiPIMS) but significant discrepancies were observed for DC magnetron operation, even at the magnetic null. For some discharge conditions, the electron density determined by Thomson scattering was over an order of magnitude greater than the plasma density obtained from the Langmuir probe, using both ion and electron collection theories. In addition, the low energy part of the electron energy distribution function determined by the probe was depleted. The possible reasons for the discrepancies are discussed, with the conclusion being that the plasma was significantly perturbed by the probe stem. The range of plasma density and electron temperature measured in the study were 0.4-5.4 x 1017 m 3 and 0.2-5.9 eV, respectively

Self-Affirmation Improves Problem-Solving under Stress

High levels of acute and chronic stress are known to impair problem-solving and creativity on a broad range of tasks. Despite this evidence, we know little about protective factors for mitigating the deleterious effects of stress on problem-solving. Building on previous research showing that self-affirmation can buffer stress, we tested whether an experimental manipulation of self-affirmation improves problem-solving performance in chronically stressed participants. Eighty undergraduates indicated their perceived chronic stress over the previous month and were randomly assigned to either a self-affirmation or control condition. They then completed 30 difficult remote associate problem-solving items under time pressure in front of an evaluator. Results showed that self-affirmation improved problem-solving performance in underperforming chronically stressed individuals. This research suggests a novel means for boosting problem-solving under stress and may have important implications for understanding how self-affirmation boosts academic achievement in school settings. © 2013 Creswell et al

People of the British Isles: preliminary analysis of genotypes and surnames in a UK control population

There is a great deal of interest in fine scale population structure in the UK, both as a signature of historical immigration events and because of the effect population structure may have on disease association studies. Although population structure appears to have a minor impact on the current generation of genome-wide association studies, it is likely to play a significant part in the next generation of studies designed to search for rare variants. A powerful way of detecting such structure is to control and document carefully the provenance of the samples involved. Here we describe the collection of a cohort of rural UK samples (The People of the British Isles), aimed at providing a well-characterised UK control population that can be used as a resource by the research community as well as providing fine scale genetic information on the British population. So far, some 4,000 samples have been collected, the majority of which fit the criteria of coming from a rural area and having all four grandparents from approximately the same area. Analysis of the first 3,865 samples that have been geocoded indicates that 75% have a mean distance between grandparental places of birth of 37.3km, and that about 70% of grandparental places of birth can be classed as rural. Preliminary genotyping of 1,057 samples demonstrates the value of these samples for investigating fine scale population structure within the UK, and shows how this can be enhanced by the use of surnames

Unexpected Fine-Scale Population Structure in a Broadcast-Spawning Antarctic Marine Mollusc

Several recent empirical studies have challenged the prevailing dogma that broadcast-spawning species exhibit little or no population genetic structure by documenting genetic discontinuities associated with large-scale oceanographic features. However, relatively few studies have explored patterns of genetic differentiation over fine spatial scales. Consequently, we used a hierarchical sampling design to investigate the basis of a weak but significant genetic difference previously reported between Antarctic limpets (Nacella concinna) sampled from Adelaide and Galindez Islands near the base of the Antarctic Peninsula. Three sites within Ryder Bay, Adelaide Island (Rothera Point, Leonie and Anchorage Islands) were each sub-sampled three times, yielding a total of 405 samples that were genotyped at 155 informative Amplified Fragment Length Polymorphisms (AFLPs). Contrary to our initial expectations, limpets from Anchorage Island were found to be subtly, but significantly distinct from those sampled from the other sites. This suggests that local processes may play an important role in generating fine-scale population structure even in species with excellent dispersal capabilities, and highlights the importance of sampling at multiple spatial scales in population genetic surveys
