Leveraging Change: Increasing Access to Arts Education in Rural Areas

In 2015, Massachusetts College of Liberal Arts (MCLA) received funding in the first round of collective impact grants from the National Endowment for the Arts to launch the pilot initiative, Leveraging Change: Improving Access to Arts Education in Rural Areas. The authors conducted research which included a literature review and interviews with arts education leaders in rural areas. Using the research compiled through this process, a pilot convening was held in western Massachusetts' Berkshire County to activate ideas, stimulate the exchange of information, and generate cross-sector collaboration focused on strengthening support for arts education in the region. This working paper is a summary of the research results and insights gleaned from this pilot initiative

Power to the People: The Tenth Circuit and the Right of Citizens to Sue for Equitable Relief Under Section 309(g)(6)(A) of the Clean Water Act

The United States Court of Appeals for the Tenth Circuit recently determined that the jurisdictional bar contained in section 309(g)(6)(A) of the Clean Water Act does not preclude citizen plaintiffs from seeking equitable relief, but only bars those actions seeking civil penalties. However, this holding by the Tenth Circuit in Paper, Allied-Industrial, Chemical and Energy Workers International Union v. Continental Carbon Co. directly conflicts with prior decisions by the First and Eighth Circuits. The First and Eight Circuits have broadly interpreted the jurisdictional bar to preclude citizens from seeking civil penalties or equitable relief once an administrative enforcement action is underway. An examination of the relevant statutory language, legislative history, and policy rationale, however, reveals that section 309(g)(6)(A) was only intended to bar citizens actions for civil penalties, preserving citizens’ powerful role in the protection and restoration of the navigable waters of this country

Magnitude and mechanisms of disequilibrium between predawn plant and soil water potentials

Journal ArticlePredawn plant water potential (Uw, measured with leaf psychrometers) and surrogate measurements made with the pressure chamber (termed Upc here) are used to infer comparative ecological performance, based on the expectation that these plant potentials reflect the wettest soil Uw accessed by roots. There is growing evidence, however, that some species exhibit substantial predawn disequilibrium (PDD), defined as plant Uw or Upc at predawn substantially more negative than the Uw of soil accessed by roots

Seedling size and survival for Chrysothamnus nauseosus

Journal ArticleSeedling size and survival in relation to summer drought were examined for Chrysothamnus nauseosus growing under field and greenhouse conditions. In the field, summer survival rates were less than 2% annually for the three years monitored. The effect of initial seedling height on subsequent survival was examined in both the field and greenhouse by grouping seedlings into live and dead categories on each census date and comparing the initial heights for seedlings in these categories. For a majority of the census dates, the initial height of surviving seedlings was greater than the initial height of those that subsequently died (significant differences ranged from 1 to 8 mm), indicating that seedlings that were taller at the initiation of the drought period had a higher probability of survival. In the greenhouse, taller seedlings had greater shoot and root biomass and rooting depth. Seedlings that are larger (i.e., taller and have greater above-ground biomass) in late spring appear to have a higher probability of surviving the summer drought due to greater rooting depth and hence increased access to moisture in deeper soil layers. Seed availability and safe sites for germination were probably not limiting since large numbers of seedlings successfully germinated in a patchy pattern during the study period. Seedling size and probability of survival were not related to either seedling density or the distance to nearest seedling neighbor. Survival through summer drought appears to be the main limitation to seedling recruitment in this population

Aesthetics of Listening: Creating Spaces of Learning

In this study with 9th-12th grade students in an urban Massachusetts school, I consider the question \u27How can theater education develop a sense of voice and identity in adolescents?\u27 Students in a drama class engaged in a variety of performance techniques including: interview theater, improvisation, and pantomime while considering the concept of voice/identity development. They then created an interview based script focused on an issue of their choice: the rules of the school and how they were enforced.... Data collection included video-taped class sessions, interviews with the drama classroom teacher, student peer interviews, and a final focus group session six weeks following the conclusion of the project

Experience of isavuconazole as a salvage therapy in chronic pulmonary fungal disease

Background: Instances of resistant fungal infection are rising in pulmonary disease, with limited therapeutic options. Therapeutic drug monitoring of azole antifungals has been necessary to ensure safety and efficacy but is considered unnecessary for the newest triazole isavuconazole. Aims: To characterise the prevalence of isavuconazole resistance and use in a tertiary respiratory centre. Methods: A retrospective observational analysis (2016–2021) of adult respiratory patients analysing fungal culture, therapeutic drug monitoring, and outcome post-isavuconazole therapy. Results: During the study period, isavuconazole susceptibility testing was performed on 26 Aspergillus spp. isolates. A total of 80.8% of A. fumigatus isolates had isavuconazole (MIC > 1 mg/L, and 73.0% > 2 mg/L) with a good correlation to voriconazole MIC (r = 0.7, p = 0.0002). A total of 54 patients underwent isavuconazole therapy during the study period (median duration 234 days (IQR: 24–499)). A total of 67% of patients tolerated isavuconazole, despite prior azole toxicity in 61.8%, with increased age (rpb = 0.31; p = 0.021) and male sex (φc = 0.30; p = 0.027) being associated with toxicity. A total of 132 isavuconazole levels were performed with 94.8% > 1 mg/L and 72% > 2 mg/L. Dose change from manufacturer’s recommendation was, however, required in 9.3% to achieve a concentration of >2 mg/L. Conclusion: We describe the use of isavuconazole as a salvage therapy in a chronic pulmonary fungal disease setting with a high prevalence of azole resistance. Therapeutic concentrations at standard dosing were high; however, results reinforce antifungal stewardship for optimization

Contrasting drought tolerance strategies in two desert annuals of hybrid origin

Woody plants native to mesic habitats tend to be more vulnerable to drought-induced cavitation than those in xeric habitats. Cavitation resistance in herbaceous plants, however, is rarely studied and whether or not annual plants in arid habitats conform to the trends observed in woody plants is unknown. This question is addressed by comparing the hydraulic properties of annual plants endemic to relatively mesic and seasonally xeric habitats in the Great Basin Desert, in both native and experimental settings. Vulnerability to cavitation between species differed as predicted when vulnerability curves of similar-sized native individuals were compared. Contrary to expectations, Helianthus anomalus from the relatively mesic dune sites, on average, exhibited higher native embolism, lower soil-to-leaf hydraulic conductance (kL) and lower transpiration rates, than its xeric analogue, H. deserticola. In transplant gardens, H. anomalus’ vulnerability to cavitation was unaffected by transplant location or watering treatment. In H. deserticola, however, vulnerability to cavitation varied significantly in response to watering in transplant gardens and varied as a function of stem water potential (Ψstem). H. deserticola largely avoided cavitation through its higher water status and generally more resistant xylem, traits consistent with a short life cycle and typical drought-escape strategy. By contrast, H. anomalus’ higher native embolism is likely to be adaptive by lowering plant conductance and transpiration rate, thus preventing the loss of root-to-soil hydraulic contact in the coarse sand dune soils. For H. anomalus this dehydration avoidance strategy is consistent with its relatively long 3–4 month life cycle and low-competition habitat. We conclude that variance of hydraulic parameters in herbaceous plants is a function of soil moisture heterogeneity and is consistent with the notion that trait plasticity to fine-grained environmental variation can be adaptive

Identification of a serum biomarker signature associated with metastatic prostate cancer

Purpose: Improved early diagnosis and determination of aggressiveness of prostate cancer (PC) is important to select suitable treatment options and to decrease over-treatment. The conventional marker is total prostate specific antigen (PSA) levels in blood, but lacks specificity and ability to accurately discriminate indolent from aggressive disease. Experimental design: In this study, we sought to identify a serum biomarker signature associated with metastatic PC. We measured 157 analytes in 363 serum samples from healthy subjects, patients with non-metastatic PC and patients with metastatic PC, using a recombinant antibody microarray. Results: A signature consisting of 69 proteins differentiating metastatic PC patients from healthy controls was identified. Conclusions and clinical relevance: The clinical value of this biomarker signature requires validation in larger independent patient cohorts before providing a new prospect for detection of metastatic PC

pH‐dependent protonation of surface carboxylate groups in PsbO enables local buffering and triggers structural changes

Photosystem II (PSII) catalyzes the splitting of water, releasing protons and dioxygen. Its highly conserved subunit PsbO extends from the oxygen‐evolving center (OEC) into the thylakoid lumen and stabilizes the catalytic Mn4CaO5 cluster. The high degree of conservation of accessible negatively charged surface residues in PsbO suggests additional functions, as local pH buffer or by affecting the flow of protons. For this discussion, we provide an experimental basis, through the determination of pKa values of water‐accessible aspartate and glutamate side‐chain carboxylate groups by means of NMR. Their distribution is strikingly uneven, with high pKa values around 4.9 clustered on the luminal PsbO side and values below 3.5 on the side facing PSII. pH‐dependent changes in backbone chemical shifts in the area of the lumen‐exposed loops are observed, indicating conformational changes. In conclusion, we present a site‐specific analysis of carboxylate group proton affinities in PsbO, providing a basis for further understanding of proton transport in photosynthesis
