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,

Conformational dependence of through-space tellurium-tellurium spin-spin coupling in peri-substituted bis(tellurides)
No full textThe work in this project was supported by the Engineering and Physical Sciences Research Council (EPSRC). M.B. wishes to thank EaStCHEM and the University of St Andrews for support.Three related series of peri‐substituted bis(tellurides) bearing naphthalene, acenaphthene and acenaphthylene backbones (Nap/Acenap/Aceyl(TeY)2 (Nap=naphthalene‐1,8‐diyl N ; Acenap=acenaphthene‐5,6‐diyl A ; Aceyl=acenaphthylene‐5,6‐diyl Ay ; Y=Ph 1 ; Fp 2 ; Tol 3 ; An‐p 4 ; An‐o 5 ; Tp 6 ; Mes 7 ; Tip 8 ) have been synthesised and their solid‐state structures determined by X‐ray crystallography. Molecular conformations were classified as a function of the two C9‐C‐Te‐C(Y) dihedral angles (θ); in the solid all members adopt AB or CCt configurations, with larger Te(aryl) moieties exclusively imposing the CCt variant. Exceptionally large J(125Te,125Te) spin–spin coupling constants between 3289–3848 Hz were obtained for compounds substituted by bulky Te(aryl) groups, implying these species are locked in a CCt‐type conformation. In contrast, compounds incorporating smaller Te(aryl) moieties are predicted to be rather dynamic in solution and afford much smaller J values (2050–2676 Hz), characteristic of greater populations of AB conformers with lower couplings. This conformational dependence of through‐space coupling is supported by DFT calculations.Peer reviewe
Income Stereotype Threat and the Consequences for Consumer Behaviour
No full textStereotype threat, the process in which we are vulnerable to the possibility of other people ascribing negative stereotypical characteristics unto us, is an increasingly popular psychological phenomenon. We are all affected by this threat, regardless of what social groups we are members of and what stereotypes are associated with them.
Existing research into stereotype threat has closely examined how gender, age and race stereotypes have affected their targets, often discovering that academic performance and internal states such as self-esteem and anxiety are negatively impacted. While these studies have provided adequate explanation for individual failures across a range of academic fields, there is an apparent lack of research concerning stereotype threat in the marketplace and how marketing efforts may be encouraging this phenomenon to occur. There is also an absence of studies delving into the area of wealth and income stereotypes. Literature has shown wealth and income stereotypes to be of great importance within society, yet no current research has examined the possibility of income stereotype threat taking place, particularly within the domain of consumer behaviour.
The purpose of the present study is to examine when and how income stereotype threat occurs within a retail environment, and how consumer and marketers may be affected. Using a quantitative approach, an online survey was conducted in order to discover what can trigger a consumer to experience income stereotype threat and the negative outcomes marketers face as a result of consumers experiencing this threat.
The study revealed that income stereotype threat occurs when consumers make upward comparisons to another shopper who is seemingly wealthier than they are. As a result, purchasing likelihood, store return likelihood and perceptions of store quality all decrease in response to the threat. It was also discovered that interacting with a store shop assistant has no effect on the outcomes of stereotype threat, regardless of how helpful or friendly they are to the shopper. While an argument is also made for income stereotype lift in this study, this effect was not present, thus future research is suggested in order to gain a better understanding of when and if income stereotype lift is possible. Future research should also aim to understand what internal states mediate income stereotype threat as this will provide a deeper understanding of the threat and its effects on individuals
A influência da tragédia na Alexandra, de Lícofron, e a questão da performance
No full textLycophron’s Alexandra is a Hellenistic poem in which a messenger reports the prophecies that he heard Cassandra pronounce within the cell where she was arrested by his father, Priam. In this poem we find a number of features that show that its author was greatly influenced by the Tragedy of the fifth century B. C. In this paper, I intend to examine the elements that characterize this influence in the poem and, in conclusion, I want to deal with the performance possibilities of such a composition. In the most recent texts of the critics, the prevailing idea is that the Alexandra would have been written for highly educated Alexandrian readers. However, I defend the idea that perhaps Lycophron has composed his poem thinking of a sort of recitation, even if it was for a highly prepared public.A Alexandra, de Lícofron, é um poema helenístico no qual um mensageiro relata as profecias que ouviu Cassandra pronunciar de dentro da cela onde tinha sido presa pelo seu pai, Príamo. Nesse poema encontramos uma série de características que mostram que seu autor foi muito influenciado pela tragédia do século V a.C. Neste trabalho, pretendo examinar os elementos que caracterizam essa influência no poema e, como conclusão, pretendo tratar das possibilidades de performance de tal tipo de composição. Nos textos dos críticos mais recentes, prevalece a ideia de que a Alexandra teria sido composta para leitores eruditos do período alexandrino. Porém, quero defender a ideia de que talvez Lícofron tenha composto seu poema pensando num tipo de recitação, mesmo que fosse para um público altamente preparado

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
Nikolai Evreinov and Edith Craig as Mediums of Modernist Sensibility
No full textNikolai Evreinov (1870-1953) was a Russian playwright, director, and theorist of the theatre who played a leading part in the modernist movement of Russian theatre. Evreinov's 1911 monodrama The Theatre of the Soul (V kulisakh dushi) was staged by the Crooked Mirror theatre in St Petersburg in 1912. It was also performed in London (1915) and Rome (1929), and inspired Man Ray to create his aerograph The Theatre of the Soul (1917). In this article Alexandra Smith links Evreinov's play to Russian modernist thought shaped by the atmosphere of crisis associated with the Russo-Japanese War and the first Russian Revolution. It demonstrates that Edith Craig's production of Evreinov's play suggests that the philosophy of theatricalization of everyday life might enable modern subjects to overcome the fragmentation of modern society. Craig's use of the montage-like techniques of Evreinov's play prefigures cinematographic experiments of the 1920s and Marinetti's notion of synthetic theatre. Alexandra Smith is a Reader in Russian Studies at the University of Edinburgh and is the author of The Song of the Mockingbird: Pushkin in the Works of Marina Tsvetaeva (1994) and Montaging Pushkin: Pushkin and Visions of Modernity in Russian Twentieth-Century Poetry (2006), as well as numerous articles on Russian literature and culture.</p
Diphtheria-like disease caused by Toxigenic Corynebacterium ulcerans strain
No full textToxigenic Corynebacterium ulcerans is an increasingly reported cause of diphtheria in the United Kingdom and is often associated with a zoonotic origin (1,2). Here, we report a case of diphtheria caused by toxigenic C. ulcerans in a woman, 51 years of age, from Scotland, UK, who was admitted to a hospital in August 2013 with a swollen, sore throat and a gray-white membrane over the pharyngeal surface. The patient had returned from a 2-week family holiday in the state of Florida, United States, before the admission and also reported recent treatment of a pet dog for pharyngitis. The patient was believed to have been vaccinated against diphtheria during childhood. She was immediately admitted to an isolation ward and treated with a combination of clindamycin, penicillin, and metronidazole
The Heterogeneity of Family Firms in CSR Engagement: The Role of Values
No full textThis study addresses the heterogeneity of family firms in their engagement with corporate social responsibility (CSR). We build on stewardship theory and socioemotional wealth to explore the foundations of CSR in family firms and to examine whether the extent of engagement is based on values, and how and why this happens. We use the interpretative method of grounded theory to address these questions. Based on 12 case studies of Spanish family firms, this article illustrates the patterns of influence of family involvement and values in explaining the extent and scope of CSRThe author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: (a) Spanish Ministry of Science and Innovation ECO2010- 21242-C03-02 Research Funding (Pilar Marques); (b) Spanish Ministry of Science and Innovation Research aid program for the Formation of University Researchers (FPU) (Alexandra Simon); (c) Autonomous Government of Catalonia 2009 SGR 577 Research Funding (Pilar Marques, Alexandra Simon
