The evolution of immigration discourse in the Maltese press from 2005 to 2015: A case study of the Times of Malta

El drama migratorio del cual está siendo Europa testigo en estas últimas semanas es en parte el resultado de una falta de políticas comunitarias en relación a este tema, hecho del cual, en los últimos años, se han hecho eco multitud de medios. Europa, y en especial los países del Mediterráneo, ha experimentado un incremento sustancial en el número de inmigrantes que llegan a sus costas en condiciones cada vez más deplorables y arriesgando gravemente su integridad física. Este hecho está principalmente motivado por el aumento y la intensidad de los conflictos bélicos en países de África y Oriente próximo. En el caso de Malta, un diminuto archipiélago ubicado entre los territorios de Libia y Sicilia, el cambio en la tendencia migratoria que se produjo en 2002 le hizo pasar de ser un país de emigrantes a un país receptor de inmigrantes. Este cambio dio como resultado la aparición de grupos y partidos anti-inmigración, como Azzjoni Nazzjonali, y de un sentimiento de preocupación frente a la llegada de inmigrantes que crece de manera constante según se refleja en encuestas europeas (véase Eurobarometer 82-83). Desde el punto de vista lingüístico, el discurso discriminatorio empleado por los medios de comunicación, organismos y figuras políticas ha sido ampliamente estudiado dentro de la rama del Análisis Crítico del Discurso (Charteris-Black, 2006; Fairclough, 1989, Reisigl & Wodak, 2001; Santa Ana, 1999; Van Dijk, 1984, 1992, 1999, 2000, 2006, Van Leeuwen & Wodak, 1999). En los últimos años, se ha potenciado el uso de un enfoque cognitivo en el análisis de este tipo de discursos. Dicho enfoque utiliza elementos tomados de la lingüística cognitiva para explicar cómo la representación de eventos y participantes en el discurso atiende, o está motivada por la conceptualización mental de dichos eventos y participantes (Charteris-Black, 2006; Hart, 2011; Musolff, 2012; Núñez-Perucha, 2011; O’Brien, 2003; Santa Ana, 1999; Van Dijk, 1992, 1998, 1999, 2000, 2006; Wodak, 2006). El Análisis Crítico del Discurso es una disciplina cuyo principal objetivo es analizar cómo ciertos fenómenos sociales que se basan en relaciones de abuso de poder y dominación se representan en el discurso de las denominadas élites (Van Dijk, 2001). Muchos de estos discursos atienden a lo que en lingüística se ha denominado discurso de discriminación, en donde un grupo dominante ejerce poder sobre otro mediante el uso de diversas herramientas discursivas. Generalmente, estos estudios sobre discursos de discriminación se han centrado en fenómenos como el machismo o el racismo. Dentro de este último campo, cabe destacar el trabajo de Van Dijk en el análisis del discurso del racismo y del discurso de la inmigración (Van Dijk, 1992, 1999, 2000, 2001, 2006). El presente trabajo se centra en analizar cómo la prensa maltesa ha representado el fenómeno de la inmigración y a los inmigrantes desde 2005 hasta 2015. Dentro de esta línea temporal, se presta especial atención al día 2 de abril de 2013. Esta es la fecha en la que la Associated Press, una organización de prensa independiente con subscriptores alrededor del mundo, decidió incluir un importante cambio léxico en su manual de estilo. El motivo del mismo era modificar el uso del adjetivo “ilegal” recomendando su uso para referirse exclusivamente a acciones (ej. Inmigración ilegal) pero nunca para referirse a individuos (ej. Inmigrante ilegal). Nuestro estudio pretende identificar hasta qué punto esta medida se ha puesto en práctica en los periódicos malteses y qué repercusiones ha tenido su incorporación en la representación de los inmigrantes y la inmigración. Para ello, se ha seleccionado como caso de estudio uno de los periódicos en lengua inglesa más leídos en el archipiélago, Times of Malta. El estudio se ha centrado en el análisis de un total de treinta artículos de opinión repartidos de manera homogénea (quince y quince) en dos corpus. El primer corpus contiene artículos pertenecientes a un periodo de tiempo que va desde 2005 hasta la fecha en la cual el cambio léxico de la Associated Press fue publicado, es decir, el 2 de abril de 2013. Por otro lado, el segundo corpus contiene artículos desde el 2 de abril de 2013 hasta mediados de 2015. Para agilizar y facilitar el análisis de los artículos, se ha hecho uso del programa llamado WordSmith Tools, el cual está especializado en el trabajo con corpus. Este programa se utilizó principalmente para analizar la representación semántica de los distintos participantes y eventos. Los resultados del análisis demuestran que el periódico ha aplicado el cambio léxico sugerido por la Associated Press al no encontrarse ningún ejemplo de “inmigrante ilegal” o “migrante ilegal” a partir del 2 de abril de 2013. En estos mismos resultados también se aprecia una representación más positiva de la figura del inmigrante en el segundo corpus, dónde el inmigrante abandona la categoría léxica de “criminal” para comenzar a ser visto cada vez más como la víctima. También a nivel léxico, se puede observar cómo los autores tienden a usar cada vez más el término “migrante” en lugar de “inmigrante”. A pesar de que este último continúa siendo el término más utilizado para referirse a la persona que llega desde otro país, el significativo incremento del uso de la palabra “migrante” en el segundo corpus es llamativo y puede deberse a que la palabra “inmigrante” haya adquirido connotaciones negativas por su repetido uso junto al adjetivo “ilegal”. De entre las estrategias discursivas empleadas en la representación de la sociedad maltesa, cabe destacar dos. Por un lado, tenemos el uso de la victimización, mediante la cual la población maltesa aparece como una víctima frente a la inmigración, que es vista como una amenaza, al mismo tiempo que Malta es también víctima de la falta de apoyo internacional. En segundo lugar, es también común encontrar artículos en donde el autor destaca las cualidades positivas de la sociedad maltesa, especialmente su generosidad. Esta última estrategia es lo que Van Dijk denomina national self-glorifiation (2000:220; 2006:738). En cuanto al uso de las metáforas, el cambio es menos significativo. En general, ambos corpus muestran ejemplos de metáforas en las que el inmigrante aparece conceptualizado como parte de un fenómeno natural incontrolable, un invasor o un organismo dispuesto a infectar o dañar de algún modo el país. En el segundo corpus, sin embargo, desaparecen las metáforas en las que el inmigrante se percibe como un animal inferior, que sí aparecían en el primer corpus. Esto supone un cambio positivo. Hasta este punto hemos resumido los cambios en la representación de los inmigrantes. Respecto al modo en el cual el fenómeno de la inmigración aparece representado en los periódicos, también encontramos cambios importantes. A nivel léxico, el cambio que mencionábamos relativo a los términos “inmigrante” y “migrante” también se produce a la hora de nombrar este fenómeno social. De este modo, la palabra “migración” es más usada en el segundo corpus que en el primero, aunque sigue ocupando el segundo lugar por detrás de la palabra “inmigración”. En cuanto a los contenidos, se puede observar un cambio positivo hacia una mayor concienciación social. Por ejemplo, vemos cómo en el segundo corpus en ocasiones se pide una respuesta estatal a temas como la integración de los inmigrantes o el racismo entre la sociedad, mientras que en el primer corpus la integración era una labor del inmigrante y el racismo era un tema incómodo. En el segundo corpus también encontramos la queja más clara hacia el uso de centros de detención en la isla. En el primer corpus, aunque algunos autores manifestaban su disconformidad con las condiciones en las cuales los inmigrantes vivían dentro de los centros de detención, todos asumían que tener dichos centros era una medida necesaria. Esta especie de consenso social y político acerca del uso de centros de detención se consigue mediante el empleo de herramientas discursivas que representen la inmigración como una amenaza de la cual hay que protegerse (negative other-presentation Van Dijk, 2000:221; 2006:738). En resumen, podemos decir que este trabajo muestra una progresión en el discurso de inmigración en Malta hacia una representación más positiva y amable del inmigrante y de la inmigración. Aunque las limitaciones de este estudio hacen imposible establecer una relación única y directa entre los cambios experimentados por el periódico y el cambio léxico sugerido por la Associated Press, lo cierto es que la descriminalización de los inmigrantes a nivel léxico (mediante la supresión de términos como “ilegal” o “detenidos”) ha influido de manera positiva en el tono y la forma en que este periódico se refiere al fenómeno social de la inmigración

"Suffragettes of the Harem": The Evolution of Sympathy and the Afterlives of Sentimentality in American Feminist Orientalism, 1865-1920

This project examines narrative encounters in space identified as “harem,” produced by authors with biographical ties to the vanguard of the American Suffrage Movement. I regard these feminists’ circulations East, to the domestic space of the Other, as a hitherto unstudied, yet critical component of transnationalism in the history of U.S. Suffrage. This literary record also crucially reveals the extent to which sentimentality was plotted as a potential force for the reform of other cultures. An urge to sympathize denied in the space of the harem illustrates the colonial anxieties that subtended sentimentality’s prospective deployment beyond national borders. In five chapters on the work of Anna Leonowens, Susan Elston Wallace, Demetra Vaka Brown, Charlotte Perkins Gilman, and Edith Wharton, I examine how Suffrage-minded authors writing the harem strategically abandon an activist praxis of fellow feeling. Such a reluctance to transform sentimental literature into a colonial literature consequently informs that genre’s postbellum decline. The sentiments that run dry for American feminists in the harem additionally foreground the costly failures of Wilsonian Idealism, a doctrine that appropriated a discourse of sentimentality in order to script the United States’ expanded involvement in global affairs.

The Roles of Phenotypic Plasticity and Plant-Microbe Interactions in the Evolution of Complex Traits in Boechera stricta

All organisms live in complex habitats that shape the course of their evolution by altering the phenotype expressed by a given genotype (a phenomenon known as phenotypic plasticity) and simultaneously by determining the evolutionary fitness of that phenotype. In some cases, phenotypic evolution may alter the environment experienced by future generations. This dissertation describes how genetic and environmental variation act synergistically to affect the evolution of glucosinolate defensive chemistry and flowering time in Boechera stricta, a wild perennial herb. I focus particularly on plant-associated microbes as a part of the plant’s environment that may alter trait evolution and in turn be affected by the evolution of those traits. In the first chapter I measure glucosinolate production and reproductive fitness of over 1,500 plants grown in common gardens in four diverse natural habitats, to describe how patterns of plasticity and natural selection intersect and may influence glucosinolate evolution. I detected extensive genetic variation for glucosinolate plasticity and determined that plasticity may aid colonization of new habitats by moving phenotypes in the same direction as natural selection. In the second chapter I conduct a greenhouse experiment to test whether naturally-occurring soil microbial communities contributed to the differences in phenotype and selection that I observed in the field experiment. I found that soil microbes cause plasticity of flowering time but not glucosinolate production, and that they may contribute to natural selection on both traits; thus, non-pathogenic plant-associated microbes are an environmental feature that could shape plant evolution. In the third chapter, I combine a multi-year, multi-habitat field experiment with high-throughput amplicon sequencing to determine whether B. stricta-associated microbial communities are shaped by plant genetic variation. I found that plant genotype predicts the diversity and composition of leaf-dwelling bacterial communities, but not root-associated bacterial communities. Furthermore, patterns of host genetic control over associated bacteria were largely site-dependent, indicating an important role for genotype-by-environment interactions in microbiome assembly. Together, my results suggest that soil microbes influence the evolution of plant functional traits and, because they are sensitive to plant genetic variation, this trait evolution may alter the microbial neighborhood of future B. stricta generations. Complex patterns of plasticity, selection, and symbiosis in natural habitats may impact the evolution of glucosinolate profiles in Boechera stricta.

The Evolution of Chimpanzee Sanctuaries in the United States

Chimpanzees are native only to the jungles of equatorial Africa, but for the last hundred years, they have also lived in captivity in the United States, most commonly in biomedical research laboratories, but also at Air Force bases for experiments for the space program, at accredited and unaccredited zoos, at circuses, as performers in Hollywood and even in private homes and backyards as pets. But that has been gradually evolving over the last few decades, as more and more chimpanzees move to newly-established chimpanzee sanctuaries. That transition was already underway even before the announcement by the National Institutes of Health (NIH) last year that it will retire all of its remaining chimpanzees from labs to sanctuaries. By thoroughly examining the evolution of these sanctuaries leading up to that seminal decision, along with the many challenges they face, including money, medical care, conflicting philosophies on the treatment of animals and the pitfalls that have led other sanctuaries to the brink of ruin, we can take away a better understanding of why chimpanzee sanctuaries are needed and why caretakers of other animal species are now looking to the chimpanzee sanctuary movement as a model to show how animals can be cared for in retirement.

Combined analysis of variation in core, accessory and regulatory genome regions provides a super-resolution view into the evolution of bacterial populations

The use of whole-genome phylogenetic analysis has revolutionized our understanding of the evolution and spread of many important bacterial pathogens due to the high resolution view it provides. However, the majority of such analyses do not consider the potential role of accessory genes when inferring evolutionary trajectories. Moreover, the recently discovered importance of the switching of gene regulatory elements suggests that an exhaustive analysis, combining information from core and accessory genes with regulatory elements could provide unparalleled detail of the evolution of a bacterial population. Here we demonstrate this principle by applying it to a worldwide multi-host sample of the important pathogenic E. coli lineage ST131. Our approach reveals the existence of multiple circulating subtypes of the major drug–resistant clade of ST131 and provides the first ever population level evidence of core genome substitutions in gene regulatory regions associated with the acquisition and maintenance of different accessory genome elements.

The evolution of lactase persistence in Europe. A synthesis of archaeological and genetic evidence

Lactase persistence, the ability to digest the milk sugar lactose in adulthood, is highly associated with a T allele situated 13,910 bp upstream from the actual lactase gene in Europeans. The frequency of this allele rose rapidly in Europe after transition from hunter–gatherer to agriculturalist lifestyles and the introduction of milkable domestic species from Anatolia some 8000 years ago. Here we first introduce the archaeological and historic background of early farming life in Europe, then summarize what is known of the physiological and genetic mechanisms of lactase persistence. Finally, we compile the evidence for a co-evolutionary process between dairying culture and lactase persistence. We describe the different hypotheses on how this allele spread over Europe and the main evolutionary forces shaping this process. We also summarize three different computer simulation approaches, which offer a means of developing a coherent and integrated understanding of the process of spread of lactase persistence and dairying.

Incised Pleistocene valleys in the Western Belgium coastal plain: Age, origins and implications for the evolution of the Southern North Sea Basin

The Belgian coastal plain occupies a key position as it is located at the transition between the Southern North Sea Basin and the Strait of Dover. It is characterized by thick sequences (> 20 m) of Pleistocene terrestrial and littoral sediments. Yet the wider stratigraphical and palaeo-environmental significance of these sediments received little attention. In this paper we draw on the results of a recent sedimentological study based on > 100 drillings that spans the Pleistocene sequence, and present new biostratigraphical (pollen, foraminifera, ostracods) data, all revealing a complex history of deposition. The record includes evidence of the development of incised-valley systems that were initiated in the late Middle and Late Pleistocene. Five phases of fluvial incision can be identified. The majority of the infills are deposited in an estuarine environment that passes into a fluvial environment land inward, except the Weichselian infill which has a predominant fluvial origin. The greatest part of the most seaward located zone of the western coastal plain was free of valley incisions, there, shallow marine sediments built up the record. Local biostratigraphical investigations provide a timeframe. The result is placed in a regional context.

The evolution of public–private partnership in Ireland: a sustainable pathway?

Ireland is a latecomer to Public Private Partnership (PPP) having only adopted it in 1998. Prior to the credit crisis, Ireland followed the UK model with PPPs being implemented in transport, education, housing/urban regeneration and water/wastewater. Having stalled during the credit crisis, PPP has been reactivated recently with the domestic infrastructure stimulus programme . The focus of this paper is on Ireland as a younger participant in PPP and the nexus between adoption patterns and sustainability characteristics of Irish PPP. Using document analysis and exploratory interviews, the paper examines the reasons for Ireland’s interest in PPP which cannot be attributed to economic rationales alone. We consider three explanations: voluntary adoption – where the UK model was closely followed as part of a domestic modernisation agenda; coercive adoption – where PPP policy was forced upon public sector organisations; and institutional isomorphism – where institutional creation and change around PPP was promoted to help public sector organisations gain institutional legitimacy. We find evidence of all three patterns with coercive adoption becoming more relevant in recent years, which is likely to affect sustainability adversely unless incentives for voluntary adoption are strengthened and institutional capacity building is boosted.

The Evolution of 'Design Build Fly' Led Teaching in Aerospace Engineering

This paper describes the evolution of a ‘Design - Build-Fly’ (DBF) approach to the delivery and assessment of a Stage Three Aircraft Design module. It focuses on the primary learning outcomes around the design and manufacturing functions associated with the development of a remotely controlled aircraft. The work covers a six year period from 2011 to present mapping the transformation of the module from report based assessment to a more hands on approach resulting in a fully functioning remotely controlled aircraft. Results show that both the staff and student experience improved across key performance metrics including student feedback, learning and competency development. Challenges still remain in methods of placing students within teams and maintaining technical rigour in reporting as students develop vocational skills and more reflective writing styles.

'Producing the Scene': the Evolution of the Director in British Theatre 1900-50

The role of the director as the individual who harnesses and controls resources to shape the theatrical product to a personal artistic vision, begins to emerge in British theatre in the early years of the twentieth century. What distinguishes the role from that of the actor-manager who had led the profession since the seventeenth century, is that it separates off from the leading actor in performance. The power and authority of the director (or producer as he or she tended to be known initially) is exercised in the pre-performance stage. In the first half of the century there were still old-style actor-managers—Donald Wolfit is a prime example—and many of the new directors had begun their careers as actors and some continued to act their in their own productions. But the perception of the function of the director began to change radically. In part this was linked to the early attempts to create a new model of producing company or ‘repertory’ theatre which required a different set of administrative as well as artistic skills to tackle the challenge of a short-run system of multiple play production. This became especially important in the developing network of regional repertory theatres which were established as autonomous, locally-specific institutions predicated on policies opposed to the dominant commercial ethos. The best-known of the early directors, most notably H.Granville Barker, confined their radical experiments to short-lived metropolitan experiments, or, as in the case of Terence Gray and J.B.Fagan, operated within the influential Oxbridge nexus. Others such as H.K.Ayliff, Herbert Prentice, William Armstrong and William Bridges-Adams remain comparatively obscure because of their long-term ‘provincial’ connections or, as in the case of Nugent Monck and Edy Craig because their creativity was largely channelled through amateur actors. This chapter will explore the evolving role of the director as both a necessary functionary and an artistic innovator within the changing structures of British theatre.

The evolution of imperfect mimicry in hoverflies

Ideas about the evolution of imperfect mimicry are reviewed. Their relevance to the colours patterns of hoverflies (Diptera, Syrphidae) are discussed in detail. Most if not all of the hoverflies labelled as mimetic actually are mimics. The apparently poor nature of their resemblance does not prevent them from obtaining at least some protection from suitably experienced birds. Mimicry is a dominant theme of this very large family of Diptera, with at least a quarter of all species in Europe being mimetic. Hoverfly mimics fall into three major groups according to their models, involving bumblebees, honeybees and social wasps. There are striking differences in the general levels of mimetic fidelity and relative abundances of the three groups, with accurate mimicry, low abundance and polymorphism characterizing the bumblebee mimics: more than half of all the species of bumblebee mimics are polymorphic. Mimics of social wasps tend to be poor mimics, have high relative abundance, and polymorphism is completely absent. Bumblebee models fall into a small number of Muellerian mimicry rings which are very different between the Palaearctic and Nearctic regions. Social wasps and associated models form one large Muellerian complex. Together with honeybees, these complexes probably form real clusters of forms as perceived by many birds. All three groups of syrphid mimics contain both good and poor mimics; some mimics are remarkably accurate, and have close morphological and behavioural resemblance. At least some apparently 'poor' mimetic resemblances may be much closer in birds' perception than we imagine, and more work needs to be done on this. Bumblebees are the least noxious and wasps the most noxious of the three main model groups. The basis of noxiousness is different, with bumblebees being classified as non-food, whereas honeybees and wasps are nasty-tasting and (rarely) stinging. The distribution of mimicry is exactly what would be expected from this ordering, with polymorphic and accurate forms being a key feature of mimics of the least noxious models, while highly noxious models have poor-quality mimicry. Even if the high abundance of many syrphid mimics relative to their models is a recent artefact of man-made environmental change, this does not preclude these species from being mimics. It seems unlikely that bird predation actually controls the populations of adult syrphids. Being rare relative to a model may have promoted or accelerated the evolution of perfect mimicry: theoretically this might account for the pattern of rare good mimics and abundant poor ones, but the idea is intrinsically unlikely. Many mimics seem to have hour-to-hour abundances related to those of their models, presumably as a result of behavioural convergence. We need to know much more about the psychology of birds as predators. There are at least four processes that need elucidating: (a) learning about the noxiousness of models; (b) the erasing of that learning through contact with mimics (extinction, or learned forgetting); (c) forgetting; (d) deliberate risk-taking and the physiological states that promote it. Johnston's (2002) model of the stabilization of imperfect mimicry by kin selection is unlikely to account for the colour patterns of hoverflies. Sherratt's (2002) model of the influence of multiple models potentially accounts for all the patterns of hoverfly mimicry, and is the most promising avenue for testing.
