Cadieux, Kirsten Valentine. „Possible moral ecologies, the function of everyday curation, and the experience of regions“. Journal of Political Ecology 23, Nr. 1 (01.12.2016): 134. http://dx.doi.org/10.2458/v23i1.20185.

Investigating the political ecologies of everyday engagements with environments—including material as well as policy and ideological interactions—requires consideration of the moral economy at play, as well as the political economy and social ecology. A.V. Chayanov (1966/1925), E.P. Thompson (1971, 1991), and Jim Scott (1976) have provided useful ways to think about moral economy. They framed moral economy as a way of enacting understandings of just commons, subsistence entitlements, and desirable economic relations based on social struggle. This framing can be particularly useful in combination with political ecology approaches to investigate 'moral ecologies.' These are society-environment assemblages that are often more aspirational than enacted, but toward which considerable effort is expended, and whose moral and ecological dynamics are functionally linked, perhaps as best illustrated in recent attention to agroecology as a powerful mechanism for ensuring rights to food (De Schutter 2011a, 2011b, 2012). Given political ecology's focus on power relations, moral ecologies that do not exercise considerable power are often overlooked by political ecologists. However, even if particular understandings may not be highly efficacious in exercising power, they may have considerable influence on relational conceptualizations. This mismatch between habitual inattention to moral ecologies and their potential importance contributes to tensions within contemporary society-environment scholarship between structuralist and poststructuralist modes of engagement. Given the value of both modes, particularly for understanding what Peet and Watts (1993) describe as liberation ecologies (and the regional discourse formations that shape them), I argue that political ecology provides useful frameworks for documenting and analyzing the socio-ecological experience of regions—in terms not only of the functions of society and environment, but also of the performance and curation of knowledge about those functions.Keywords: moral economy, food systems, curation, critical regional studies, land use planning, participatory action research, environmental justice, integrated natural resource management science

This essay describes strategic approaches to graphic representation associated with critical environmental engagement and that build from the idea of works of architecture as stitches in the ecological fabric of the city. It focuses on the building up of partial or fragmented graphics in order to describe inclusive, open-ended possibilities for making architecture that marry rich experience and responsive performance. An aphoristic approach to crafting drawings involves complex layering, conscious absence and the embracing of tension. A self-critical attitude toward the generation of imagery characterized by the notion of ‘loose precision’ may lead to more transformative and environmentally responsive architectures.

Science teachers' career satisfaction and organisational climate, which influence their job performances, are very important. This research examined the extent to which science teachers' career satisfaction and organisational climate are related to their job performances in rural learning ecologies. Within a survey and correlational research design of a quantitative type, 250 science teachers were selected in Ondo State, Nigeria using a purposive sampling technique. Data were collected using an adapted questionnaire on science teachers' career satisfaction, school organisational climate and job performance. Descriptive and inferential statistics were used to analyse data. The results showed that 65.2% of the science teachers in rural learning ecologies were satisfied with their careers while 34.8% were dissatisfied with their careers. It was discovered that a combination of career satisfaction and organisational climate significantly influenced their job performances. It was found that the teachers’ career satisfaction had a significant positive effect on their job performances while school organisational climate had a significant negative effect on their job performances. In light of the results, it can be concluded that science teachers' career satisfaction is the most effective significant contribution to their job performances. Further, it can be inferred that the school organisational climate does not significantly predict job performance in rural learning ecologies. To this end, results of the current research have some implications worth considering for the employers of science teachers, principals of schools and other stakeholders in creating a healthy school organisational climate and demonstrate good leadership behaviour in order to achieve improvement in the job performance of science teachers in rural learning ecologies. Keywords: school organisational climate, science education, teachers’ career satisfaction, teachers’ job performance, rural learning ecologies.

In what would a postmodern theatrum mundi, or ‘theatre of the world’, consist? In an ironic inversion of the very concept, with the microcosm issuing a unilateral declaration of independence – or of incorporation? Or in a neo-neoplatonic recognition that it is but a cultural construct of an outer world that is itself culturally constructed? In the following article, Baz Kershaw makes connections between the high-imperial Victorian love of glasshouses, which at once created and constrained their ‘theatre of nature’, and the massive 'nineties ecological experiment of ‘Biosphere II’ – ‘a gigantic glass ark the size of an aircraft hangar situated in the Southern Arizona desert’, which embraces all the main types of terrain in the global eco-system. In the Biosphere's ambiguous position between deeply serious scientific experiment and commodified theme park, Kershaw sees an hermetically-sealed system analogous to much contemporary theatre – whose intrinsic opacity is often further blurred by a theorizing no less reductive than that of the obsessive Victorian taxonomists. He offers not answers, but ‘meditations’ on the problem of creating an ecologically meaningful theatre. Baz Kershaw, currently Professor of Drama at the University of Bristol, originally trained and worked as a design engineer. He has had extensive experience as a director and writer in radical theatre, including productions at the Drury Lane Arts Lab and as co-director of Medium Fair, the first mobile rural community arts group, and of the reminiscence theatre company Fair Old Times. He is the author of The Politics of Performance: Radical Theatre as Cultural Intervention (Routledge, 1992) and The Radical in Performance: Between Brecht and Baudrillard (Routledge, 1999), and co-author of Engineers of the Imagination: the Welfare State Handbook (Methuen, 1990).

Indigenous chickens were evaluated for their egg production, growth performances, and external and internal egg quality parameters across three agro-ecologies. For experiment 540 (180 male and 432 female) chickens were distributed to the three agro-ecologies (lowland, midland, and highland) at their 20 weeks age. Body weight was recorded from each chicken during distribution, 4th week, and 8th week after distribution into pre-selected households. Egg production potential was identified from the indigenous chickens across different agro-ecologies. Moreover, egg quality traits were evaluated from randomly selected 270 (90 from each agroecology) eggs. Egg production of indigenous chickens in the highland was 47.7 which was highly significantly (P = 0.0001) lower number than of midland (54.2) and lowland (51.4). Except for Shell weight, all the external egg quality parameters evaluated were exhibited significant differences across different agro-ecologies. Among the internal egg quality parameters only albumen weight had a significantly (P = 0.007) higher in midland than highland. Most of the variation in egg weight was due to the positive correlation with egg length (69%), and egg width (67%). There was a variation for performance and egg quality traits of indigenous chickens in different agro-ecologies, especially better in midland, which might be resulted from the variation in environment, feed resources availability, and better management followed by households.

This article explores an ecodramaturgical approach to performance-making and research with algae. The first part considers the notion of ‘algae rendering’ as a methodological tool for theorising algae ecological relations which highlights links between representations of algae and their material effects. The second part considers how my embodied encounters with cyanobacteria algae, in the form of lichen, inspire new modes of working with algae in creative practice that explore how algae agencies ‘render’ bodies and environments. I also draw on an artistic case study by The Harrissons (1971) to illustrate principles of what I consider examples of ‘algae rendering’ in artistic practice. The third part considers my approach to making-with algae in a series performance experiments that develop the concept of ‘rendering-with algae’ in practice. This work attempts to depart from anthropocentric binaries that mark different algae species according to their use-value for humans as either ‘healthy’ or ‘harmful’ and investigates embodied ways of working with algae as co-creators, inspired by material ecological relations. The fourth part considers how these performance encounters, experiments and analysis together compose an ecodramaturgical framework that generates new thinking about algae-human relationships in performance and in wider ecologies. Drawing on Donna Haraway’s (2016) concept of ‘sympoiesis’, I develop the term ‘algae sympoiesis’ to describe my embodied ecodramaturgical approach to rendering-with algae in this research. The concept of algae sympoiesis explores how humans and algae shape matter and meaning together in performance and seeks to invite new ways of thinking about how broader algae-human material ecologies are performative of environmental change.

I write about butoh through a prism of Zen and phenomenology because they share similar philosophical outlooks on performance, and they explain everyday things. In articulating performance in the everyday, the progress of this reflective essay takes a somatic turn inward to matters of consciousness and ecosomatic convergence of body and nature. The several threads of this article relate through matters of ‘suchness’, a non-dual principle of Zen spanning several kinds of Buddhism. Suchness as perceptual oneness arises through meditative or neutral attention without attachment or need. I understand suchness in performance as attentive, generous presentation and witnessing ‐ these propelled by acumen and guidance more than criticism. Judgements can have simple good sense in suchness too. An attitude of suchness accepts things as they are, and people and performances as they are, whether in personal relationships or on the stage. Expectations are not lowered through suchness; they are open to curiosity and wonder. The article further develops ecosomatic performances for the reader to experience.

University managers are forced to assume responsibility for more and more aspects of academic life. This essay focuses on academic publishing and how deans and department heads attempt to manage the volume and quality of publications at their university because others, including politicians and scholars, rate the quality and effectiveness of the university on their publication output. How managers assume and practice this responsibility for academic publishing may seem self-evident but proves to hide both paradoxes and loopholes. Reflections build on an empirical illustration derived from the adoption of a conventional publication strategy. The implementation of this strategy is fueled by a large dose of strategic expediency. However, such expediency incurs costs related to impression management when managers need to show a sense of command in response to a disappointing performance. Both material costs (time and money) and symbolic costs (demonstrating allegiance to an embarrassingly naive conception of academia) are incurred. Exactly because management is exercised on the premise of an embarrassingly naive conception of academia, the presumed coercive forces are exceedingly loose and ineffective. The room for value judgment at all levels of the university organization is not closed but rather enshrined (for good or bad) behind a façade of objectivity and factuality.

Audience engagement with a sound work can extend beyond fixed conventions in which roles of creation and reception are separate. In an ‘open work’ these roles are blurred, and the audience takes on an active part of co-creation. Participatory sound works can be considered as ecologies of engagement rather than fixed compositions. Technologies of dissemination and interactivity have become part of the design of such ecologies, and sound artists have integrated them in highly diverse works. Two main aspects of participatory ecologies will be considered: the continuum of ‘active interpretation’ to ‘co-authorship’ and the creation of a community of intersubjectivity. These two aspects will be discussed in the context of a range of sound works, including the author's work Shadowgraphs (2009/11) and its interconnected manifestations: an installation, a live performance and a blog.

Mannerism was the bridge between late Renaissance and the Baroque between 1520 and the 1600s. This movement was characterized by the destabilization of compositional elements through repetition and expressiveness, regardless of their function. This phase in history echoes a trend in contemporary architecture based on the repetition of functionless elements that constitute a ‘green aesthetic’ in detriment of sustainable systems. Ecomannerism is a conceptual vehicle to identify and evaluate iconic contemporary projects that are positioned between ecologies of practice and ecologies of symbols, which are directly related to the sustainable performance of the built environment.

When charities launch capital campaigns, they hope to attract large amounts of resources in a relatively short period of time; however, other charities in the area are likely to see such campaigns as disruptive to the natural distribution of resources to area nonprofits by disproportionately directing area donations to a single organization. This study seeks to understand the effects capital campaigns have on both the fundraising performance of other nonprofits and the makeup of a local nonprofit ecology. The analysis uses data from a randomly sampled set of nonprofit arts organizations that had capital campaigns for facilities projects between 1994 and 2007 and Internal Revenue Service Form 990 data on 501 (c) (3) nonprofit organizations in each county. The results illustrate that a capital campaign positively affects the fundraising performance of other charities in a local nonprofit ecology, but that campaigns decrease the size of a local nonprofit ecology.

Honeybee colonies exhibit a wide range of variations in their performance, depending on genetic and environmental factors. However, there has been little research carried out on Apis mellifera bandasii (A. m. bandasii) populations to characterize their behavioural performance. To gain insight into the details of the behavioural performance of this local honeybee, we characterized and compared the colony performance of honeybee populations at different altitudes. Fifty honeybee colonies per site, making a total of 150 colonies, were established at Bako (mid-highland), Gedo, and Holeta (highland). The colonies were evaluated for brood-rearing activities, resource collecting, brood solidity, swarming, defensive and hygienic behaviours, and honey yield parameters. The average brood areas were determined to be 6114.13 ± 500.36, 3298.30 ± 365.92, and 2521.23 ± 244.67 cm2 per colony; the average nectar areas were found to be 3399.46 ± 738.88, 1238.78 ± 228.96, and 1883.09 ± 232.57 cm2 per colony; the average number of queen cells was determined to be 0.62 ± 0.30, 1.20 ± 0.39, and 2.19 ± 0.49 per colony; the average percent of pin-killed broods removed was determined to be 93.78 ± 1.74, 96.42 ± 1.86, and 80.09 ± 7.86 per colony; the average percent of colonies absconded was determined to be 36, 54, and 46 per site at Holeta, Gedo, and Bako, respectively. The mean differences among the locations for brood areas, nectar areas, number of queen cells, percent of pin-killed broods removed, and percent of colonies absconded were significant ( p < 0.05 ), while the variations in the area of stored pollen, brood solidness, and honey yield were not significant. Significant variation within colonies of the same apiary of the same subspecies was observed. These results showed that A. m. bandasii at Holeta had the best performance and that Bako had the lowest performance. Therefore, the variability in colony performances indicates the possibility of improving strains of native stocks through selection and breeding strategies using the variations as an opportunity.

The Surveillance Camera Players, from New York City, are a performance based activist-awareness group who openly, critically, and playfully engage various elements of public surveillance. This discussion with Bill Brown, co-founder of the Surveillance Camera Players, covers the group’s history, the strategy of their public performances and, during the winter months, their weekly walking camera tours. Furthermore, Brown critiques the growth of the surveillance society and how it continues to reify a culture of public conformity and increasingly enforces a dangerous homogeneity of behavioral display across our social ecologies.

The aim of this research is to identify and analyse the ubiquitous learning acquired though blending education settings devoted to the 'lifelong training of trainers' and how these contribute to the development of a conscious, critic and engaged citizenship. Through active exploration of the learning process, the study analyses the 'soft skills” acquired which enhance performance in work and daily life, with the purpose of detecting the process of ubiquitous learning often overlooked in formal education. To this end, the study case presented here draws upon a data triangulation of qualitative and quantitative multisource information (questionnaires, interviews, participant observation, discussion groups, individual and collective diaries) which includes the study of the semantic networks consisting of learners’ own utterances. The results obtained indicate that the soft skills related to the capacity of selfdevelopment, the use of innovative resources, the enhancement of social cooperation, the ability to meet cognitive and social challenges, and the functional learning as produced though expanded learning, have the potential to pave the way for the empowerment of peoples, communities and social movements. But this form of expanded learning, as open, collaborative, democratic and committed learning, must be actively supported if future generations are not only to be consumers but also cooperative producers in a socially shared world. El objetivo de este trabajo ha sido detectar y analizar los aprendizajes ubicuos adquiridos en entornos educativos expandidos destinados a la «formación permanente de formadores» y cómo estos influyen en la construcción de una ciudadanía consciente, crítica y comprometida. Se han analizado las «soft skills» adquiridas para el desenvolvimiento efectivo en el trabajo o la vida diaria, mediante la exploración activa del proceso formativo. Se ha tratado así de detectar el aprendizaje ubicuo que suele resultar invisible para la educación formal. Con este propósito, el estudio de caso aquí presentado recurre a una triangulación de análisis cualitativo y cuantitativo de información multifuente (cuestionarios, entrevistas, observación participante, grupos de discusión, diarios individuales y colectivos), que incluye análisis de red semántica de las expresiones de los participantes. Los resultados obtenidos nos indican que las «soft skills» relacionadas con la capacidad de desarrollo autónomo, el uso de medios y recursos transformadores, la potenciación de la cooperación social, la resolución de desafíos cognitivos y sociales, la potenciación del compromiso cívico y del aprendizaje funcional, que genera el aprendizaje expandido, se pueden convertir en un instrumento para el empoderamiento de personas, colectivos y movimientos sociales. Pero este aprendizaje expandido, como aprendizaje abierto y colaborativo, democrático y comprometido, requiere un apoyo consciente si se desea que las futuras generaciones no solo sean consumidoras, sino productoras colaborativas en un mundo socialmente compartido

Der volle Inhalt der QuelleAnnotation:
Act Three of William Shakespeare’s and John Fletcher’s The Two Noble Kinsmen features a scene, written by Fletcher, in which a Schoolmaster named Gerald teaches his students a Morris dance. Fletcher’s depiction of Gerald and pupils is a rare moment in early modern drama in which the humanist pedagogical praxis is acted on stage. In this essay, I draw on recent scholarship on dance, embodied performance and cognitive ecologies of the stage and classroom to illustrate the way in which the Morris dance functions as a complex commentary on performance ecologies and Humanist pedagogical methodology. I argue that throughout this scene, Gerald teaches his pupils how to dance by using the movements and terminology associated with actio, a performance of rhetoric in which the student used his body to act out his lesson. While actio was supposed to be an embodied experience comprised of both outward gestures and inward reflection, Fletcher satirizes the Gerald’s lack of mental awareness behind his movements, questioning whether rhetorical training could produce genuine, cognitive learning. Reading the Morris dance scene in this way illustrates the complexity of Fletcher’s contribution to The Two Noble Kinsmen. Fletchers undergirds this comedic moment with a serious critique of humanist schoolroom methodology.

The study focus on the evaluation of popcorn lines for their yield and agronomic potentials. Genetic materials were evaluated under irrigation in a three-replicate in a Randomized Complete Block Design (RCBD) with a commercial variety as check. Two seeds were planted per hole using two- row plots of 5 m long with inter and intra-row spacing of 0.75 m x 0.5 m, respectively in two locations viz: Ibadan and Ikenne representing the forest and savannah agro-ecologies of Nigeria respectively. Genotypes (G) differed significantly (ρ ≤ 0.01) for almost all the characters measured except for ear aspect. Location (L) as well as G x L interaction effects were also well pronounced on all agronomic characters measured except for days to silking and ears per plant. Popcorn 33-1-Y, large pearl shaped, Popcorn 40-Y and Popcorn 34-Y were high yielding with a potential of above 2.0 t ha−1. These materials were found to be fairly resistant to major foliar diseases of the tropical humid ecologies. They are recommended for further evaluation across different agro-environments for possible propagation by popcorn farmers in Nigeria to boost production.

Abstract This article builds a framework for considering the place of contemporary performance groups in 21st century Bangkok. It grounds performance groups in ensembles of performance practices developed by groups as part of their unique performance cultures. The varied ensembles of performance practice of three such groups – the Pichet Klunchun Dance Company, the 8X8 Theatre Group, and the B-Floor Artist Collective – are embodied in these groups’ distinctive interactive performance styles and tied to the different creative spaces where they work. The groups’ artistic practices and their working spaces are produced within larger ecologies of performance spanning the urban landscape of 21st century Bangkok. The article suggests this framework as a richer way to study performance cultures in Thailand. Relating the performance landscape of Bangkok’s contemporary theatre scene to the embodied artistic practices of different groups shows how their unique performance cultures help to enliven the city’s distinctive cultural ecology of performance.

Aim: The study aimed to evaluate ten wheat cultivars along with 45 F1 under different environments to identify best suited environment for potential expression of grain yield and related traits under terminal heat stress. Methodology: Ten wheat cultivars and 45 F1 were evaluated under three different environments at Rajasthan Agricultural Research Institute, Durgapura, Jaipur (SKNAU, Jobner). The experiment was carried out in randomized block design with 3 replications and each plot had 2 rows for F1 and 4 rows for parents with 30×10 cm spacing. The parents of the crosses were selected on basis of their superiority in performance across diverse ecologies. Results: The results of present investigation revealed that first two principal components contributed to nearly 63 % of total variance that is grouped in two clusters. Genotype plus genotype by environment interaction view revealed top cultivars and hybrids under terminal heat stress conditions. AMMI biplot analysis indicated environment 1 and environment 2 as the best suited environments for potential expression of grain yield and related traits. The study identified potential donors, cultivars C306, Raj4079, Raj1482 and PBW396 for earliness and cultivarsCR43, CR20 and PBW590 for grain yield and related traits under terminal heat stress conditions. Interpretation: The grain yield can be improved by selecting for higher grain number, biomass and harvest index as revealed from their positive correlations. The presence of G×E interaction provides the opportunity to select for the stable genotypes for diverse ecologies. On other hand, environment specific genotypes can be targeted in befitting ecologies. AMMI and GGE biplot based stability analysis prove to be an efficient approach in testing the genotypes performance in multi-environment trials for selection of stable heat resilient cultivars.

The outcomes of IEA's Trends in International Mathematics and Science Study (TIMSS) conducted from 1995 to 2002 confirmed that there was no improvement in the learning outcomes of grade eight learners in Mathematics and Science. Additionally, the failure rate in Mathematics at the National Senior Certificate (NSC) Matriculation examination has increased from 2008 to 2018 in South African schools. It was consequent on this decline in performance that the South African National Roads Agency Limited (SANRAL) Chair in Science and Mathematics Education developed a short learning intervention programme for Mathematics teachers in South Africa in 2013 and 2014. This research reports post-intervention instructional practices of five teachers at Reitz who took part in the intervention programme. The teachers took part in the training workshops that were orgnised for participants at the University of the Free State, implemented the knowledge acquired from the programme in their respective schools, and compiled an evidence portfolios of their post-intervention instructional practices. The portfolios of evidence submitted by the teachers were thus analysed to give voice and meaning to their post-intervention instructional practices and reflections. The analyses provide evidences of which aspects of their instructional delivery worked well while other aspects did not work well.

Abstract This article considers choreographer Ligia Lewis's hour-long ensemble performance Water Will (in Melody) to theorize on the relationship between ecological fugitivity and black fugitive movement. It explores how Lewis's choreography disrupts the colonial space-times of colonialism and slavery by offering portals into other space-times. In Water Will (in Melody), racialized assemblages break down from overuse and from glaring surveillance in the form of illumination. The last few minutes of the piece evoke an ambivalent postapocalyptic space-time where darkness becomes textured with what seems to be moonlight peeking into a wet cave. This ending evokes the ecological of histories of fugitivity and the earthiness of Édouard Glissant's concept of opacity, both frequently overlooked in discussions of black fugitivity. The final section traces Lewis's fugitive choreography into what the article calls the barbed ecologies of the hills of the Dominican Republic and Haiti, sites of black and indigenous marronage and symbiosis.

Abstract. The layperson’s view associates aging with biological and cognitive losses, which could be associated with decrements in work productivity and overall contributions to society. In turn, ecological approaches to life span development suggest that successful performance can result from an adaptive employment of an individual’s physical, cognitive, or social capital in the appropriate environment. This ecological framework suggests that one must understand the demands of particular ecologies (i.e., niches) to predict whether aging is associated with failure, maintenance, or even improvements in performance. We provide examples that illustrate the importance of an ecological approach to understanding adaptation to challenging decision tasks both in the laboratory and in the wild. Overall, we propose that there are specific strategies and niches that can help older adults thrive and that more work is needed to understand the exact characteristics that lead to good performance in old age.

Abstract Three sessions of international and local participants from a July 2019 conference created active ecosystems which generated living examples of intercultural improvisation, performance research, cultural ecologies and artistic research in Thailand. Summarized and assessed in this article, these sessions revealed some of the first fruits of Thailand’s work in these areas through engagement with other practitioners in the region. Besides offering creative improvisation among Thai artists and artist-centered critical assessments of their work, the article captures active thinkers seeking to reimagine the “festival” format for performance research, and seeks for ways to continue future regional collaboration in artistic research. The article embodies the ecological aspects of live collective thinking in the arts.

To identify superior quality protein maize genotypes for grain yield under different agro climatic conditions of terai and hill districts in Nepal, the coordinated varietal trials (CVT) were conducted at Dailekh, Doti, Salyan, Lumle and Pakhribas in 2013 and Salyan, Pakhribas and Kabre in 2014 during summer season and coordinated farmer’s field trials (CFFT) at Surkhet and Dailekh in 2013 and Salyan, Pakhribas and Khumaltar in 2014 during summer season. The experiment was carried out using randomized complete block design with three replications for CVT and CFFT. Across the locations and years the superior genotypes found under CVT were S01SIYQ, S01SIWQ-2 and Poshilo Makai-1 where as S99TLYQ-HG-AB, S99TLYQ-B and Poshilo Makai-1 were found superior genotypes under CFFT. The superior genotypes derived from CFFT will be promoted further for similar environments across the country.Journal of Maize Research and Development (2015) 1(1):21-27DOI: http://dx.doi.org/10.5281/zenodo.34282

Affordance theory, originating in ecological psychology but adopted by the field of design studies, refers to possibilities for action that a subject perceives in an environment. I posit Black spatial affordance, critically employing affordances with an eye toward Black ecological and geographical practices, and I apply it to the Great Migration residential landscape and literature. Grounded in racial capitalist critique, Black geographic thought, and cultural critique at the intersections of race, place, and performance, Black spatial affordance works as an analytic to engage Black quotidian practice in racially circumscribed and delineated places and spaces. Operating at multiple scales, Black spatial affordance engages the specificity of places structured by racism to analyze the micro-level spatial negotiations Black subjects devise and employ in recognition of the terrain through which they move or are emplaced. Employing Black spatial affordance enables critical inquiry into the spatial navigation of subjects who occupy marginal positions in society.

Cashew (Anacardium occidentale L.) is an important tropical cash crop cultivated in Ghana. It provides livelihood for about 200,000 people and contributes 6.1% to Ghana’s gross domestic product (GDP). Four Brazilian dwarf accessions were introduced to improve nut yield. Objectives of this study were to (1) assess the agronomic performance of the accessions across two contrasting ecologies, (2) determine environmental influence on juvenile growth, (3) determine the relationship between early vegetative growth and yield and (4) explore heritability and genetic advance for the measured agronomic traits. The experiment was laid out in a randomized complete block design with 3 replications. Results revealed significant (p < 0.05) environmental influence on growth and yield of cashew. Transitional savanna agro-ecology is more suitable for cashew growth and development. Crop year, location and crop year × location interactions also influenced most of the agronomic traits. Early growth characteristics alone were not enough to predict yield. Genotype B2 ranked highest yielding across the agro-ecologies. Moderate to high heritability and genetic advance estimates were observed for nut yield, plant height and girth, an indication of variability among accessions needed for cashew improvement in Ghana.

Differential performance of genotypes in different cultivation environments has remained a challenge to farmers and plant breeders, the emphasis being the selection of high yielding and stable genotypes, across similar ecologies. A set of nine cowpea genotypes were cultivated in Ago-Iwoye and Ayetoro, two locations representing high and moderate moisture zones. Plantings were done with the early and late season rains in Ago-Iwoye and mid-late season rains of Ayetoro. Statistical analysis was done to understand genotype reaction to the different environments and the plant and environment factors mediating the performance. The Additive Main Effect and Multiplicative Interaction (AMMI) model captured 61.30% of the total sum of squares (TSS). The main effects: genotype (G) environment (E) and their interaction (GxE) were significant with the largest contribution of 28.70% by the environment while the interaction and genotype fractionscaptured 20.20% and 12.40%, respectively. The percentage contribution of the main effects and GxE to total sum of squares (TSS) for traits was not consistent. The Genotype plus Genotype-by-Environment (GGE) analysis summarized 91.30% of the variation in genotype performance across environment. The cultivation environments were separated into two, with IT 95M 118 as the vertex genotype in the Ayetoro while TVU 8905 was the topmost genotype in Ago-Iwoye. The two genotypes recorded the highest grain weight per plant (GWPP) but were also the most unstable The stable genotypes IT 95M 120 and IT 86 D 716 flowered relatively late compared to others, are taller, had higher vegetative score and are low grain producers.

Abstract This article reflects on the sociopolitical, cultural, and health landscape(s) of our current moment in time, addressing how intersecting crises have delivered us to an unprecedented moment for drama, theatre, and performance. As communities across the world have had to dispense with staples of everyday life – attending live theatre performances being one of these –, so art, in all its forms, has never been more significant in its capacity to bring us together, even if modes of togetherness have shifted in their referentiality and locationality. As the article proposes, we need to take an intuitive approach to the appreciation of how our ecologies – in their broadest iteration – have been impacted and realigned by the COVID-19 pandemic in such ways that we can expect that our future scholarship(s) on plays, place, and landscape will and, indeed, ought to reflect this experience. Dialogues on theatre and environment, which are already intersectional, are now receiving yet another focusing lens through the pandemic.The article also suggests that our understandings of how our ecologies have been adapted invite a consideration of new modes of engaging with the environment in our discourses – and of the very term itself and what it might encompass – and new economies in calibrating our discourses to reflect our radically redistributed individual and collective experiences. The text offers examples of categories that emerge particularly strongly where spatial liminality is key; in so doing, it asserts that in-betweenness is a central element towards understanding our contemporary role and responsibilities: from collapsing binaries (environment/economy) to the unmoored experience of our times.

Lack of improved maize variety is highly limited in different parts of Ethiopia due to inaccessibility of different production factors. Guji Zone is one of such areas where the technologies are not widely addressed and adopted so far. This study was conducted by Bore agricultural research center with the objective of selecting and recommending adaptable high yielding and early maturing maize varieties for mid land agro-ecologies of Guji zone. The experiment was done at three locations Adola on station and two farmer’s field (Dole and Kiltu Sorsa). Six (6) released maize varieties with one local check were used. RCBD experimental design with three (3) replications was used on plot size of 5mx6m. All phonological and yield data were collected subjected to analysis using GenStat (18th edition) software. Combined data analysis was used to test the performance of the varieties across the testing locations. The result of the study shows that, all varieties revealed significant difference for the selected characters across the locations. Based on the obtained result, two Maize varieties (MH-140 and BH-546) were early maturing and gave higher yield .Therefore; these varieties were selected and recommended for the study area and similar agro-ecologies of Guji Zone.

Drought and limited availability of water serve as the serious limitation for rice production in rainfed ecosystems. Among the major rainfed rice-cultivating areas, states of eastern India occupy one of the largest drought-prone ecologies in the world. Cultivating drought tolerant rice varieties can serve as the most coherent approach to ensure food security in these areas. International Rice Research Institute (IRRI), along with its national collaborators, has developed drought tolerant rice varieties possessing high yield along with desirable grain quality. One such conventionally bred line, IR74371-70-1-1, has been released with different names in the different countries: in India as Sahbhagi Dhan, in Nepal as Sukha Dhan 3, and in Bangladesh as BRRI Dhan 56. This indicates the suitability of this line to show better performance across the wide range of environments. Sahbhagi Dhan is a short duration variety that has genetic drought tolerance and is more efficient at extracting available moisture from the soil. During drought years, farmers cultivating Sahbhagi Dhan obtained the yield advantage of 0.8 to 1.6 t ha−1 over currently grown long duration as well as traditional varieties. In 2012, when the paddy crop was hit by drought, Sahbhagi Dhan revealed the yield advantage of more than a t ha−1, which reduced to 0.78 and 0.56 t ha−1 during non-drought years of 2013 and 2014, respectively. Data taken from head to head trials during 2017 showed that Sahbhagi Dhan exhibited better performance over the existing rice varieties grown by farmers even under non-drought conditions. The important feature of Sahbhagi Dhan is its evident impact under drought and no yield penalty under favorable conditions over the counterfactual varieties of the same duration. Along with better yield under drought, the important advantage of Sahbhagi Dhan is the short maturity duration of this variety. This allows the farmers to advance the succeeding crop and creates an opportunity for accommodating an additional crop under favorable rainfed ecology, thereby enhancing the cropping intensity. Since the majority of the farmers living in drought prone ecologies are socio-economically under privileged, Sahbhagi Dhan, along with other drought tolerant varieties, can serve as one of the most viable and deliverable technologies for eradicating poverty from these ecologies dependent on rainfed rice.

Fall armyworm (FAW) Spodoptera frugiperda (J.E. Smith) and southern armyworm (SAW) Spodoptera eridania (Stoll) have become major threats to crops in Africa since 2016. African governments adopted emergency actions around chemical insecticides, with limited efforts to assess the richness or roles of indigenous natural enemies. Field surveys and laboratory studies were conducted to identify and assess the performance of parasitoids associated with spodopterans in Cameroon. FAW was the most abundant spodopteran pest. Telenomus remus (Nixon), Trichogramma chilonis (Ishi), Charops sp. (Szépligeti), Coccygidium luteum (Cameron), Cotesia icipe (Fernandez & Fiaboe), and Cotesia sesamiae (Cameron) are the first records in the country on spodopterans. Telenomus remus, T. chilonis, C. icipe, and Charops sp. were obtained from both FAW and SAW; C. luteum and C. sesamiae from FAW. The distribution of spodopterans, their endoparasitoids, and parasitism rates varied with host, season and location. In the laboratory, T. remus showed significantly higher parasitism on FAW than SAW, and significant differences in the development parameters between the two host eggs, with shorter development time on FAW. It induced significant non-reproductive mortality on FAW but not on SAW. Developmental parameters showed that C. icipe has a shorter development time compared to other larval parasitoids. Implications for conservative and augmentative biocontrol are discussed.

Chickpea is among the major pulse crops grown in southern Ethiopia including Borana and West guji zone. The area has potential to the production of Chickpea for food and nutrition security as well as export commodity. However, scarcity of varieties that fit to the environment is one of the major constraints of production. Therefore, this experiment was conducted to evaluate 9 chickpea varieties to select adaptable varieties for yield and agronomic traits. The field experiment was conducted in 2017 and 2018 at two locations (Abaya and Bule hora) and varieties were planted in Randomized complete block design. Data were collected on yield and important agronomic traits. Analysis of variance computed for individual locations and combined analysis over locations revealed significant variations among varieties. Moreover, Varieties showed a grain yield as high as 1087.5kg/ha and 873.79kg/ha at Bule hora and Abaya respectively. Minjar variety is significantly high yielding variety at both locations with yield advantage of 26.13% and 52.07% over variety mean at Bule hora and Abaya respectively and therefore recommended for both locations and locations with similar agro ecologies.

The ephemerality of music is a consuming philosophical problem; it is also a practical dilemma for archivists and researchers. For oral traditions such as Indian classical music, notations, recordings and transcriptions fail to capture much of what is communicated in musical performance, which problematizes the creation and function of archives. This article explores an approach to archiving musical practices in relation to constitutive processes of emplacement, a complex I denote by the term ‘thick sound’. Using a rich and historic Dhrupad tradition as a case study, I discuss how I used documentary, material, aural, embodied and sensory performance data to construct my archive. I investigate the ways in which such documentation captures ecologies of music-making and the challenges posed for the analysis of histories of (thick) sound. I conclude by discussing the implications for theorizing archival work as active intervention, mediating relationships of past, present and future.

Heat stress resilience in maize hybrids is emerging as an important trait in germplasm targeted for cultivation in the post-rainy season spring in South Asia. One of the major challenges in targeted breeding for these agro-ecologies is the differential response of maize genotypes to heat stress across locations during the spring season. This study is targeted at identifying the major environmental variables that contributed to the genotype × environmental (GEI) yield variations observed among genotypes grown in response to heat stress. The trial dataset used for this study constitutes 46 trials × location combinations spread over a period of three years (2013-2015). Partial least square (PLS) regression analysis was implemented to decipher the important environmental variables contributing to the observed yield variation among maize trials planted during spring across locations of South Asia. The first two factors from the PLS study explained the 30 per cent yield variation across trials. The largest contributor of this variation was relative humidity (RH) and vapor pressure deficit (VPD) during flowering stage of the crop across the years.

Data sources were surveys for sample teachers and students in 20 schools on how often a teaching or evaluation strategy was used in various courses. The study concluded that most teachers were able to adopt most of the reforms. Even though teacher-directed lessons still dominated, there were sufficient student-centered lessons. Tests, exams, and performance tasks were used for evaluations. However, classroom management needs increased attention. More resources and professional development are needed. Policymakers and educators in all jurisdictions can learn from the reform efforts.

The Twelve (12) pure lines and a local check were evaluated in Nine (9) locations for two years. Combined Analysis and Stability Models were employed. The genotype EXPL03-10-01 had the tallest plants in the population, recorded the highest yield of 810.30kg/ha at Ryom and an overall combined yield of 696.09kg/ha. Finlay-Wilkinson stability model identified the genotype EXPL03-10-01 in the presence of changes in environmental quality, genotype x environment interaction (GEI) shows 30% higher than 1 in 2019 and 32% less than 1 in 2020 for slopes value having significant t-values in both years. GGE biplot analysis of grain yield indicated that, PC1 and PC2 explained a total of 66.3% and 15% of GGE sum of observed variations respectively. AMMI model deployed revealed that greater portion of total variability in the grain yield of the Fonio lines was contributed by the environments. G1 (EXPL03-10-01) was not only an ideal genotype in majority of the tested environments but was also found to be more stable than other genotypes according to GGE Biplot.

The highest total seed yield was recorded from genotypes 242826-2 followed by 242826-2 (24.54 and 23.32 Qt ha-1) while the lowest total seed yield was obtained from local checks. These two genotypes have yield advantage of 22.41 and 14.96% over standard check Derbera. Based on their performance across location over standard checks these two genotypes will be promoted for variety verification for Bale mid altitude and similar agro ecologies.
