    Get PDF
    The ethnic news media (ranging the gamut from newspapers to broadcast programs to online ventures) have experienced rapid growth in tandem with the changing nature of the nation's demographics, yet considerable anecdotal evidence shows that many of these outlets struggle with a variety of serious problems, ranging from poor journalistic standards to sheer survivability as businesses. The study was designed to provide an assessment of the sector's health and resiliency and to identify threats to success, primarilyfrom the perspective of its staff and leaders

    Plant microbiome - The physiology of symbiotic plant nutrition

    Get PDF
    Plants used to be regarded as individuals, but we know now that their phenotypes result from a complex multitude of genomes, known as the plant microbiome. Intriguingly, the same types of microbes keep showing up across the same plant varieties, species or even families. This is the core microbiome that is winnowed from what is a highly complex and diverse soil microbial community. In a healthy soil, plants create a gradient of microbial diversity with a steep decline closer to the roots, then on the roots and finally inside the plant, where perhaps only 200 species gain a pass. Plants actively recruit microbes that can provide them with services, from nutrient sequestration to suppressing pathogen growth. A number of ‚Äėgood‚Äô bacteria have now been linked to heightened resilience and yield in the face of drought, heat stress, salinity and plant disease. Inoculating crops with these could not only improve yields but also fight off disease without the need for chemicals or genetic modification. In this work we review and integrate the mechanisms allowing the symbiotic functionality between plants and microbes and give hypothesis on how to boost yields by managing microorganisms.Universidad de M√°laga.

    Disserta√ß√£o de Mestrado em Teoria da Literatura e Literatura PortuguesaMagalh√£es, n√£o √© um cr√≠tico que √© poeta, nem t√£o pouco um poeta que √© cr√≠tico. Cr√≠tico e poeta s√£o formas complementares de pensar o fen√≥meno liter√°rio. E poucos, na segunda metade do s√©culo XX, se dedicaram de forma t√£o atenta √† an√°lise da poesia portuguesa contempor√Ęnea. Muitas vezes pol√©mico, seguramente controverso, avesso a consensos, fez luz sobre muitos nomes do panorama po√©tico actual e recuperou alguns nomes ‚Äďjusta ou injustamente - ignorados pelo tempo Na primeira parte do nosso trabalho, abordamos a obra ensa√≠stica de Magalh√£es - Os Dois Crep√ļsculos; Um Pouco De Morte e Rima Pobre. Neste sentido, procuramos mostrar a influ√™ncia do pensamento de F.R. Leavis e de T.S. Eliot no seu exerc√≠cio cr√≠tico e analisamos as rela√ß√Ķes, nem sempre pac√≠ficas, de Magalh√£es com uma esfera p√ļblica fragment√°ria e pouco participativa. Achamos prof√≠cuo distinguir a no√ß√£o de modernismo da no√ß√£o de vanguarda, pois estes conceitos s√£o usados de forma pouco precisa por Magalh√£es. Este tende a confundir a ideia de vanguarda com a urg√™ncia do novo, com uma l√≥gica de supera√ß√£o, quando de facto o projecto vanguardista √© uma tentativa de reconduzir a arte √† praxis vital. A arte deve desautonomizar-se. No centro das preocupa√ß√Ķes de Magalh√£es est√° tamb√©m o p√ļblico, ou melhor os p√ļblicos. A massifica√ß√£o da res liter√°ria trouxe p√ļblicos que n√£o procuram o caminho da facilidade. At√© a poesia, conotada com a high culture e com uma sensibilidade maior e minorit√°ria, foi afectada por um p√ļblico pouco esclarecido, consumidor de emo√ß√Ķes alheias e facilmente iludido pelo aparato ret√≥rico-discursivo de certa poesia. Num segundo momentodo nosso trabalho, centramo-nos na obra po√©tica de Magalh√£es, distinguindo tr√™s momentos capitais, a saber, a reescrita de toda a obra publicada at√© 1985 em Alguns Livros Reunidos (mantendo aut√≥nomas apenas duas obras); as obras onde o vincar do negrume √© por demais evidente (especial relevo para Uma Luz com toldo vermelho e a Poeira levada pelo vento) e, finalmente, os poemas publicados em O Independente e coligidos em Alta Noite em Alta Fraga. Na √ļltima parte, tomamos de empr√©stimo um conceito do √Ęmbito da geologia ‚Äď recristaliza√ß√£o - para melhor entendermos a revisita√ß√£o tem√°tica feita nos poemas publicados em O Independente, e posteriormente coligidos em Alta noite Alta Fraga. A esfera p√ļblica, a aus√™ncia de uma moral, a pequenez, a degrada√ß√£o f√≠sica, a velhice, o destruir da paisagem (a √ļltima das utopias), a falta de um espa√ßo habit√°vel, a morte, a devasta√ß√£o invadem este textos eleg√≠acos. O desencanto, o negrume √© tanto que nem a pr√≥pria morte √© uma certeza de paz. ‚Äď ¬ęS√≥ nos resta esperar ent√£o morrer?¬Ľ (Magalh√£es, 2001f:80). A poesia de Magalh√£es √© cada vez mais uma √©tica do fim

    From Bildungsroman to Bildungsromance: Physical and Affective War in Chinelo Okparanta’s Under the Udala Trees

    Get PDF
    The bildungsroman has dominated the Nigerian literary landscape since the 1990s with novels such as Chimamanda N. Adichie‚Äôs Purple Hibiscus (2004), Unoma Azuah‚Äôs Sky-High Flames (2005), Chika Unigwe‚Äôs Night Dancer (2012), and Chinelo Okparanta‚Äôs Under the Udala Trees (2015). These coming-of-age stories place a special emphasis on the national evolution of Nigeria. Thus, by delving into such interrelation of the national and personal domains, I propose to theorize Under the Udala Trees as a ‚Äúbildungsromance,‚ÄĚ or novel of affective and romantic development. I use the term ‚Äúbildungsromance‚ÄĚ to describe the growth of Okparanta‚Äôs protagonist, Ijeoma, as intrinsically associated with the experiences gathered from her affective attachments both in the public and the private spheres. I will analyze Ijeoma‚Äôs sentimental relationships as she discovers and naturalizes her queer identity. For this, I will delve into the negative affects ‚ąí in the form of fear, shame and guilt (Braidotti 2009, 50) ‚ąí that influence Ijeoma‚Äôs experience as a result of her non-conforming to the dictums of Nigerian customary laws. Ironically, such negative affects will be introduced as tightly associated with ‚Äúthe promise of happiness‚ÄĚ (Ahmed 2010, 14). In turn, I shall underline the role of Ijeoma‚Äôs intimate and romantic relationships in prompting positive forms of affect such as self-love and pride. These affective experiences allow Ijeoma to acquire a critical perspective towards Nigerian customary laws and their impact on identity formation and on what has been referred to as the ‚Äúdemocratisation of the private sphere‚ÄĚ (Giddens 1992, 184). Ultimately, I will hinge upon Ijeoma‚Äôs awareness of her own affective advancements as a key element in her bildungsromance.This article was completed under the grant PID2021-122249NB-I00 funded by MCIN/AEI/10.13039/501100011033 and ‚ÄúERDF A way of making Europe‚ÄĚ, whose support the autor gratefully acknowledges

    Habitat Variation in Vernal Pool Ecosystems on Both Sides of the Strait of Gibraltar

    We studied vernal pool (VP) ecosystems along a latitudinal gradient crossing the Strait of Gibraltar in order to determine its role in the distribution of VP plant communities. We analyzed flora, vegetation, physical‚Äďchemical water parameters, and climatic data from two vernal pool areas on both the European (Iberian) and African (Moroccan) sides of the Strait. Despite the minor distance between both territories, the pools clearly differed in species composition and ecology. However, they showed a similar vegetation zonation in growth forms, including isoetid, batrachiid, and helophytic vegetation. The distribution of the plant communities was related to nutrient load, temperature, and precipitation. Water nitrate concentration was higher in Morocco, where VPs are characterized by Isoetes velata subsp. adspersa and Ranunculus saniculifolius communities. Iberian VPs had lower water nitrate content, and were characterized by Isoetes velata subsp. velata and Ranunculus peltatus communities. We think this nutrient difference is likely to be caused by the different land management regime on each side of the Strait, with more intensive agriculture in Morocco. Long-term (historical) and present-day (ecological) processes have been proposed to account for the habitat variation in vernal pool ecosystems on both sides of the Strait of Gibraltar

    Contextual factors and contingent reward leadership: employer adoption of telecommuting

    Get PDF
    Using a contingency perspective, this paper examines the conditions under which telecommuting is most likely to be adopted with data obtained from a sample of 122 CEOs. We hypothesized that telecommuting fits better in younger organizations, firms with a higher proportion of women and international employees in workforce, and companies that offer variable pay. We found evidence that confirm the prediction that telecommuting, a high proportion of international employees, and the use of variable compensation as an internal control mechanism tend to go hand in hand.
