Stages for the More Sustainable Farm
No full textCurrently, agricultural farm units are faced with a double and most times contradictory challenge, in order to be successful: on the one hand the invested capital has to be profitable and the economic performance has to be maximised. On the other hand, given the socio-environmental situation, it is necessary to preserve and to protect the environment and natural resources. Given the potential conflict of the two aims, since the satisfaction of one implies the underperformance of the other (and vice versa), the question then is: which is the solution to choose? We intend, in this work, to formulate a farm plan with the purpose of reconciling the criteria of environmental sustainability with that of economic competitiveness. For this achievement we proceed to the comparative study of sustainability of different groups of farms identified in the study area (first evaluation cycle) through MESMIS (“Marco para la Evaluación de Sistemas de Manejo de Recursos Naturales Mediante Indicadores de Sustentabilidad” - Framework for Evaluation of Natural-Resource Systems Handling through Sustainability Indicators) methodology, that allowed to select the more sustainable group of farms. Based on the found potentialities and weakness on these production systems, we stepped to the planning of a production unit of bovine meat, which obeys simultaneously to economic and environmental objectives, using Multicriteria Decision. We finished the work with the sustainability evaluation between groups of farms identified previously and the planned farms (second evaluation cycle), based, again, in the MESMIS methodology, to confirm (or not) the greatest sustainability of the last ones. Analyses of the results allow us to confirm the greatest relative sustainability of the planned farm, for the diverse traced scenarios.Decision taking, planning, sustainability, Environmental Economics and Policy, Farm Management,
TRAGIC NOISE AND RHETORICAL FRIGIDITY IN LYCOPHRON'S ALEXANDRA
No full textAbstract This paper seeks to shed fresh light on the aesthetic and stylistic affiliations of Lycophron's Alexandra , approaching the poem from two distinct but complementary angles. First, it explores what can be gained by reading Lycophron's poem against the backdrop of Callimachus’ poetry. It contends that the Alexandra presents a radical and polemical departure from the Alexandrian's poetic programme, pointedly appropriating key Callimachean images while also countering Callimachus’ apparent dismissal of the ‘noisy’ tragic genre. Previous scholarship has noted links between the openings of the Aetia and of the Alexandra , but this article demonstrates that this relationship is only one part of a larger aesthetic divide between the two poets: by embracing the raucous acoustics of tragedy, Lycophron's poem offers a self-conscious and agonistic departure from Callimachus’ aesthetic preferences. Second, this article considers another way of conceiving the aesthetics of the poem beyond a Callimachean frame, highlighting how Lycophron pointedly engages with and evokes earlier Aristotelian literary criticism concerning the ‘frigid’ style: the Alexandra constructs its own independent literary history centred around the alleged name of its author, ‘Lycophron’. The article proposes that this traditional attribution is best understood as a pen name that signposts the poem's stylistic affiliations, aligning it not so much with the Ptolemaic playwright Lycophron of Chalcis but rather with Lycophron the sophist and a larger rhetorical tradition of stylistic frigidity. Ultimately, through these two approaches, the article highlights further aspects of the Alexandra 's aesthetic diversity
Teaching empathy and emotions : J. M. Coetzee's "The lives of animals" and human-animal studies
No full textIn "Teaching Empathy and Emotions: J. M. Coetzee's 'The Lives of Animals' and Human-Animal Studies," Alexandra Böhm focuses on one of the most influential novels in the field of HAS. In her article, she delineates the two main difficulties in teaching Coetzee's text: firstly, the text's protagonist, fierce and fearless Australian author Elizabeth Costello, is often less-than-lovable and offers few grounds for identification; secondly, the text's multilayered structure further problematizes the authorial voice. However, by focusing on Costello's reassessment of emotion and empathy, Böhm convincingly demonstrates that Coetzee's text offers possibilities for understanding the key concepts of HAS, such as animal agency, alterity, and the necessity of assuming a non-anthropocentric perspective. In the narrative, Costello employs empathy in her approach to animals, but is this also true of the metadiegetic level of Coetzee's text? Does the text itself suggest how to teach empathy? Alexandra Böhm demonstrates that it is possible to elicit affective responses to these questions through emotion journals and role-playing
Addressing the challenges of climate change risks and adaptation in coastal areas: A review
No full textClimate change is and will continue altering the world's coasts, which are the most densely populated and economically active areas on earth and home for highly valuable ecosystems. While there is considerable relevant research, in the authors' experience this problem remains challenging for coastal engineering. This paper reviews important challenges in this respect and identifies three key actions to address them: (a) refocusing traditional practice towards more climate-aware approaches; (b) developing more comprehensive risk frameworks that include the multi-dimensionality and non-stationarity of their components and consideration of uncertainty; and (c) building bridges between risk assessment and adaptation theory and practice. We conclude that the way forward includes numerous activities including increased observations; the attribution of coastal impacts to their drivers; enhanced climate projections and their integration into impact models; more impact assessments at the local scale; dynamic projections of spatially-distributed exposure and vulnerability; and the exploration of inherently adaptive options. Given the complexity of the possible solutions, more practical guidance is required.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Coastal Engineerin

Exploring the model minority: views of Asian American students on school climate with implications for school professionals
No full textWhen Asian students are seen as the model minority, pressures to conform and meet high expectations combined with discrimination and harassment may serve to negatively influence how Asians view their school climate. The current study seeks to examine views of the school climate by Asians as a function of their majority/minority status in their schools, as well as variability within Asian subgroups. By examining the students’ perceptions of overall school climate, student respect, student friendship and belonging, students’ shaping of their environment, and student support and care by staff, this study seeks to empirically examine the notions that have been demonstrated largely theoretically and anecdotally. In addition, this study seeks to examine the moderating effects of ethnic composition of the school on Asian students’ perception of school climate. Data were collected from completion of the Developing Safe and Civil Schools School Community Survey (Elias, 2009), a self-report questionnaire. Participants consist of 10,401 sixth to twelfth grade students from 25 New Jersey public schools who were enrolled in the Developing Safe and Civil Schools (DSACS) Project, directed by Maurice J. Elias, Ph.D., during the years 2006-2007. A series of ANCOVA analyses were used to examine differences on aspects of school climate based on ethnicity, Asian subgroup, and ethnic composition of the school, while controlling for the effects of DFG. Asians held higher views than Blacks and Latinos on overall school climate, student friendship and belonging, and student respect. Asians had higher perceptions of students’ shaping their environment than Whites, Blacks, and Latinos. Asians had lower perceptions of student support and care by staff than Whites. Southeast Asians held higher views than East Asians on student support and care by staff. With regard to ethnic composition of school, non-White dominant schools had higher perceptions of overall school climate than White dominant schools. Asian dominant schools had higher views of student respect than White dominant schools. In non-White dominant schools, Asians held higher views on overall school climate than Asians in White dominant schools. Relationship of findings to the literature, limitations, and implications of the current study for practice and research are discussed.Psy.
