Ecodrama and Sustainable Theatre: A Handbook for Creating Remarkable Change
The climate crisis is not new to us, nor are the art forms that have taken shape as vital components of the many activist movements that seek to save the planet. Yet, for the first time at Pomona College, a play about environmental devastation and our hand in it finally graced the stage of this progressive institution this past year. This mini handbook is a call-to-action (of sorts), one that stems from the idea that this should not be the last ecodrama performed at Pomona College. These chapters are structured and supported by both experience and research – formulated from what I have learned from advocating for and helping to produce an ecodrama for the college’s mainstage season. This documentation will provide the foundation for a path forward, including next steps the college and theatre department can take, and the most prominent limitations of this institution as it pertains to producing ecodramas and sustainable art. It is my hope that ecodramas are more seriously considered in future season planning and that this mini-guide paints a path forward for progress as a department and an institution
La formación de profesores en los Grados en USA: instantáneas del paisaje
[EN] The U.S. does not have a federal certification for teaching at the university level mandating graduatelevel training in pedagogy. Nevertheless, the field of Graduate Assistant Training is thriving in America and has produced several models that fit a variety of institutional contexts. This chapter reviews training models at 3 institutions: Kennesaw State University, Carnegie Mellon University, and University of Colorado–Boulder. From these models, we extrapolate common successes and point out some unresolved issues that characterize the U.S. landscape.[ES] Los EE.UU no tienen una certificación federal en el nivel universitario que ordene una formación pedagógica para la enseñanza en los niveles de grado. Sin embargo, el ámbito de la Formación para los Graduate Assistant (asistentes de Grado) está creciendo en los Estados Unidos y ha producido varios modelos que se ajustan a una variedad de contextos institucionales. Este texto analiza los modelos de formación en tres instituciones: la Universidad Estatal de Kennesaw, la Universidad Carnegie Mellon y la Universidad de Colorado-Boulder. A partir de estos modelos, extrapolamos los éxitos y los puntos comunes a algunas cuestiones no resueltas, que caracterizan el paisaje de EE.UU. Dipietro, M.; Buddie, AM. (2013).

Comments on "Mycobiota and Mycotoxins in Traditional Medicinal Seeds from China. Toxins 2015, 7, 3858-3875"-in Attributing Ochratoxin A Biosynthesis Within the Genus <i>Penicillium </i>Occurring on Natural Agricultural Produce
The unusual attribution of trace amounts of ochratoxin A in some Chinese food commodities to Penicillium polonicum is questioned by European experience in searches for ochratoxinogenic food-spoilage Penicillia, where mistaken attribution is now known to have been due to cryptic Penicillium verrucosum contamination. Consequently, selection of single-spore isolates is recommended as pre-requisite for attributing mycotoxin biosynthetic potential to fungi
Anisotropic Small-Polaron Hopping In W:Bivo4 Single Crystals
DC electrical conductivity, Seebeck and Hall coefficients are measured between 300 and 450 K on single crystals of monoclinic bismuth vanadate that are doped n-type with 0.3% tungsten donors (W:BiVO4). Strongly activated small-polaron hopping is implied by the activation energies of the Arrhenius conductivities (about 300 meV) greatly exceeding the energies characterizing the falls of the Seebeck coefficients' magnitudes with increasing temperature (about 50 meV). Small-polaron hopping is further evidenced by the measured Hall mobility in the ab-plane (10(-1) cm(2) V-1 s(-1) at 300 K) being larger and much less strongly activated than the deduced drift mobility (about 5 x 10(-5) cm(2) V-1 s(-1) at 300 K). The conductivity and n-type Seebeck coefficient is found to be anisotropic with the conductivity larger and the Seebeck coefficient's magnitude smaller and less temperature dependent for motion within the ab-plane than that in the c-direction. These anisotropies are addressed by considering highly anisotropic next-nearest-neighbor (approximate to 5 angstrom) transfers in addition to the somewhat shorter (approximate to 4 angstrom), nearly isotropic nearest-neighbor transfers.

The Role of Women’s Alcohol Consumption in Managing Sexual Intimacy and Sexual Safety Motives
Objective: Two studies, based on an alcohol myopia model, were designed to understand the role of women’s alcohol consumption on vulnerability to sexual assault. We predicted that, in a high-conflict social situation, alcohol would make it more difficult to recognize sexual assault risk, lowering intentions to resist sexual advances.
Method: In Study 1, women (N = 51) were recruited in bars and classified as having a high (.06 or greater) breath alcohol concentration (BrAC) or low BrAC. They were asked to project themselves into a hypothetical scenario that portrayed interest in establishing an intimate relationship and included mild sexual aggression. In Study 2. women (N = 101) were randomly assigned to an alcohol (target BrAC: .08%), placebo, or no-alcohol condition. They responded at two time points to a similar hypothetical scenario that described mild sexual aggression (Time 1) and serious sexual aggression (Time 2).
Results: In Study 1, women with higher BrAC perceived less risk in the scenario and anticipated less resistance than women with low BrAC. In Study 2, similiar results were found but only following serious aggression. There were no placebo effects. Both studies suggest that effects of alcohol on resistance are partially mediated via risk perceptions.
Conclusions: Alcohol appears in reduce intentions to resist sexual advances from an acquaintance while increasing intentions to pursue relationship-enhancing behaviors. Effects are not completely explained by an alcohol myopia perspective. Differences in findings between the two studies may reflect differences in methodology, context, or sample
Parasitoid complex of fall armyworm, spodoptera frugiperda, in Ghana and Benin
Open Access Journal; Published online: 21 Jan 2020The fall armyworm, Spodoptera frugiperda, a moth originating from the American continent, has recently invaded most African countries, where it is seriously threatening food security as a pest of cereals. The current management methods rely heavily on the use of synthetic insecticides but there is a need for more sustainable control methods, including biological control. Surveys were conducted in two West African countries, Ghana and Benin, to determine the native parasitoid complex and assess parasitism rates of S. frugiperda. Samples of S. frugiperda eggs and larvae were collected in maize fields located in 56 and 90 localities of Ghana and Benin, respectively, from July 2018 to July 2019. Ten species were found parasitizing the pest, including two egg parasitoids, one egg–larval, five larval and two larval–pupal parasitoids. The two most abundant parasitoids in both countries were two Braconidae: the egg‐larval parasitoid Chelonus bifoveolatus and the larval parasitoid Coccygidum luteum. Parasitism rates were determined in three Ghanaian regions and averages varied from 0% to 75% between sites and from 5% to 38% between regions. These data provide an important baseline for the development of various biological control options. The two egg parasitoids, Telenomus remus and Trichogramma sp. can be used in augmentative biological control and investigations should be conducted to assess how cultural practices can enhance the action of the main parasitoids, C. luteum and Ch. bifoveolatus, in the field. Understanding
the parasitoid complex of S. frugiperda in Africa is also necessary before any development of classical
biological controls involving the introduction of parasitoids from the Americas
Exploring Voice as Integration: A Direction for Assessing Student Work in Learning Communities with Composition
Kennesaw State University’s team of interdisciplinary scholars qualitatively assessed student learning within theme-based learning communities to determine whether content from one discipline was evident in student work produced within another discipline. Faculty concluded that they were likely expecting more disciplinary integration than first-semester college students were capable of providing, and that they were likely not asking for the integration they were expecting. By examining student work as evidence, the researchers became more acutely aware of the assignment instructions, prompting them to work more closely with colleagues in their future learning communities to develop interdisciplinary assignments with explicit expectations for integration
Diversidad genética de Chondrostereum purpureum (Pers.) Pouzar causante del plateado en arándano en Chile
Blueberry (Vaccinium corymbosum L.) in Chile is being affected by silver disease whose causative agent is Chondrostereum purpureum (Pers.) Pouzar. This fungus causes a decrease in the yield of the fruit and the death of the plant. So far, this disease has not been reported in the literature attacking blueberry plants in Chile. The main objective of this research was to characterize genetically the populations of Ch. purpureum at molecular level using the ITS-RFLP markers. The results of the ITS-RFLP indicate a low level of diversity in the Chilean populations of Ch. purpureum. When analyzing the isolates collected in blueberry, two large groups were configured in the dendrogram. The first one grouped 49 isolates with the same molecular profile and in the second cluster there was a greater diversity among the isolates. On the other hand, when we analyzed Ch. purpureum isolates collected in other hosts, 12 isolates constituted a group with identical molecular profile with the 49 isolates collected from blueberry. Analysis of variance of the molecular data showed that there were no statistical differences between Ch. purpureum collected in different areas or in different hosts.El arándano en Chile está siendo afectado por la enfermedad del “plateado” cuyo agente causal es Chondrostereum purpureum (Pers.) Pouzar. Este hongo produce una disminución en el rendimiento de la fruta y la muerte de la planta. Hasta ahora, esta enfermedad no se ha reportado en la literatura atacando plantas de arándano en Chile. El objetivo principal de esta investigación fue caracterizar genéticamente las poblaciones de Ch. purpureum a nivel molecular utilizando los marcadores ITS-RFLP. Los resultados de los ITS-RFLP indican un bajo nivel de diversidad en las poblaciones Chilenas de Ch. purpureum. Al analizar los aislados recolectados en arándano se configuraron en el dendrograma dos grandes grupos. El primero de ellos agrupó 49 aislamientos con el mismo perfil molecular y en el segundo cluster hubo una mayor diversidad entre los aislados. Por otro lado, cuando se analizaron aislados de Ch. purpureum recolectados en otros huéspedes, 12 aislados constituyeron un grupo con idéntico perfil molecular con los 49 aislados recolectados de arándano. El análisis de varianza de los datos moleculares mostró que no había diferencias estadísticas entre Ch. purpureum recolectado en zonas diferentes o en diferentes huéspedes
Molecular diversity of anthracnose pathogen populations associated with UK strawberry production suggests multiple introductions of three different Colletotrichum species.
Fragaria × ananassa (common name: strawberry) is a globally cultivated hybrid species belonging to Rosaceae family. Colletotrichum acutatum sensu lato (s.l.) is considered to be the second most economically important pathogen worldwide affecting strawberries. A collection of 148 Colletotrichum spp. isolates including 67 C. acutatum s.l. isolates associated with the phytosanitary history of UK strawberry production were used to characterize multi-locus genetic variation of this pathogen in the UK, relative to additional reference isolates that represent a worldwide sampling of the diversity of the fungus. The evidence indicates that three different species C. nymphaeae, C. godetiae and C. fioriniae are associated with strawberry production in the UK, which correspond to previously designated genetic groups A2, A4 and A3, respectively. Among these species, 12 distinct haplotypes were identified suggesting multiple introductions into the country. A subset of isolates was also used to compare aggressiveness in causing disease on strawberry plants and fruits. Isolates belonging to C. nymphaeae, C. godetiae and C. fioriniae representative of the UK anthracnose pathogen populations showed variation in their aggressiveness. Among the three species, C. nymphaeae and C. fioriniae appeared to be more aggressive compared to C. godetiae. This study highlights the genetic and pathogenic heterogeneity of the C. acutatum s.l. populations introduced into the UK linked to strawberry production
