Narratives great and small: neighbourhood change, place and identity in Notting Hill

The area of Notting Hill in west London has been subject to much media coverage in recent years, which, along with substantial gentrification, has given rise to an image of the area as the epitome of fashionable London. This study investigates the views of those marginal to gentrification and mediated representation on their feelings about the local area, its image and their changing neighbourhoods. Many participants in the research resented some of the more recent changes in Notting Hill and the area's representation in the media. However, in contrast to expectations, most of the more working-class respondents involved in the research did not articulate much emotional attachment to the area. They were more concerned with what might be termed the material aspects of life in Notting Hill: convenience, facilities, safety and so on. In contrast, the more middle-class respondents frequently spoke of their regret of the changes to the area, such as the loss of independent shops, and the reduction in diversity. Paradoxically, the loss of working-class landscapes seems a relatively middle-class worry. The symbolically important landscapes described by working-class respondents were related to more immediate, material issues, in which gentrification was only a relatively minor concern.

Seamount abundances and abyssal hill morphology on the eastern flank of the East Pacific Rise at 14 degrees S

Bathymetric data from a Hydrosweep multibeam sonar survey of a 720 km long tectonic corridor on the east flank of the southern EPR at 14 degrees 14'S covered about 25,000 km(2) of zero-age to 8.5 m.y. old crust (magnetic anomaly 4A). In this corridor we document a strong correlation of robust along flowline changes in abyssal hill morphology and seamount size distribution with spreading rate changes deduced from our magnetic data. Indeed, we find that both rms height of abyssal hills and abundance and height of seamounts increase significantly as spreading rate changes from similar to 75 mm/yr to over 85 mm/yr (half rate). Moreover, we identified 46 seamounts taller than 100 m. Previous studies on the southern EPR reported a larger density of seamounts, organized primarily in chains. Our investigation, however, revealed seamounts not associated with major chains, leading us to the conclusion that different forms of off-axis volcanism occur along the spreading center.

From Hill to Harbor: Serving Water and People on Baltimore's Civic Waterfront

People and cities alike derive their life from water. Water is consequently influenced by the actions of people and cities. This crucial relationship deserves to be commemorated, and also analyzed as further human development, sea level rise, and ecological remediation efforts influence its form. This thesis seeks to remember the past condition, recognize the current, and positively influence the future of this relationship in Baltimore’s Inner Harbor through a waterfront park and harbor history museum. How can a building and a site work together to improve the health of local hydrology while still effectively serving its human community? This thesis weaves these opportunities together to create a responsible redesign of Rash Field and Federal Hill on the south side of the Inner Harbor in Baltimore.

Liian pitkiä taukoja puhutun puheen aikana – miss�� viipyy tekstitys? Yleisradion ohjelmatekstitysten laatu ja saavutettavuus kohdeyleisön näkökulmasta

Tutkielmassa käsitellään Yleisradion ohjelmatekstitysten laatua ja saavutettavuutta pääasiallisten kohderyhmien näkökulmasta. Lähtökohtana tutkimukselle toimivat kolme hypoteesia, joiden mukaan ohjelmatekstitysten ensisijaiset kohderyhmät olisivat tyytyväisimpiä ja toissijaiset kohderyhmät tyytymättömämpiä ohjelmatekstitysten laatuun, toissijaisia katsojaryhmiä ei olisi huomioitu riittävästi ohjelmatekstityksiä tehdessä sekä ohjelmatekstitysten saavutettavuutta voitaisiin parantaa. Tavoitteena oli siis selvittää Yleisradion ohjelmatekstitysten laadun ja saavutettavuuden taso katsojalähtöisesti kyselytutkimuksen muodossa. Katsojien mielipiteitä ohjelmatekstityksestä kerättiin Webropol-työkalulla toteutetun kyselyn avulla. Vastauksia toivottiin saatavan ainakin ensisijaisilta katsojaryhmiltä eli kuuroilta ja kuulovammaisilta, sekä lisäksi eläkeläisiltä ja maahanmuuttajilta, joiden on myös havaittu hyötyvän ohjelmatekstitysten käytöstä. Kysely toteutettiin yhteistyössä asiantuntijatahojen, kuten Yleisradion, katsojaryhmien etujärjestöjen ja edustajien kanssa. Pääasiassa suljettuja kysymyksiä ja Likert-asteikkoon pohjautuvia väittämiä sisältävä verkkokyselylomake oli avoinna yleisölle julkisen linkin kautta vuoden 2013 kevään ja kesän ajan. Kyselyyn vastasi yhteensä 84 ohjelmatekstitysten käyttäjää. Kyselyn alussa kartoitettiin vastaajien taustoja ja televisionkatselutottumuksia, jonka jälkeen kyselyssä keskityttiin selvittämään vastaajien mielipiteitä Yleisradion ohjelmatekstityksen laadusta ja saavutettavuudesta. Ohjelmatekstityksen laatua koskevissa kysymyksissä perehdyttiin seuraaviin tekijöihin: puheen tekstittäminen, ohjelmatekstitysten vaikutus television katseluelämykseen, tekstityksissä käytettävät värit, infokyltin käyttö ja muiden äänten tekstittäminen. Lisäksi vastaajilta tiedusteltiin esimerkiksi mitä mieltä he ovat ohjelmatekstitysten käyttöönoton helppoudesta. Kerätyistä vastauksista kävi yllättäen ilmi, että toisin kuin ensimmäisessä hypoteesissa oletettiin, tyytyväisimpiä esimerkiksi ohjelmatekstityksissä käytettyyn kieleen ja tekstitysten positiiviseen vaikutukseen kielenoppimisessa ja ylläpitämisessä ovat toissijaisista katsojaryhmistä ainakin maahanmuuttajat. Täten myös toinen hypoteesini kumoutui, sillä kyselyyn saadut vastaukset osoittivat, että huolimatta aiemmista tutkimuksista, ensisijaisten katsojaryhmien eli kuurojen ja kuulovammaisten tarpeita ja toiveita tulisi sittenkin tutkia lisää ja tämän myötä ottaa ne paremmin huomioon ohjelmatekstityksiä toteutettaessa. Tutkimuksen tuloksista kävi lisäksi selville, että Yleisradion ohjelmatekstitysten laadun yleiseen tasoon ollaan suhteellisen tyytyväisiä katsojien keskuudessa. Ainoastaan viimeiseen hypoteesiini eli tarpeeseen parantaa ohjelmatekstitysten saavutettavuutta sain kannatusta kyselyn vastaajilta.

Efficient Hill Climber for Constrained Pseudo-Boolean Optimization Problems

Efficient hill climbers have been recently proposed for single- and multi-objective pseudo-Boolean optimization problems. For $k$-bounded pseudo-Boolean functions where each variable appears in at most a constant number of subfunctions, it has been theoretically proven that the neighborhood of a solution can be explored in constant time. These hill climbers, combined with a high-level exploration strategy, have shown to improve state of the art methods in experimental studies and open the door to the so-called Gray Box Optimization, where part, but not all, of the details of the objective functions are used to better explore the search space. One important limitation of all the previous proposals is that they can only be applied to unconstrained pseudo-Boolean optimization problems. In this work, we address the constrained case for multi-objective $k$-bounded pseudo-Boolean optimization problems. We find that adding constraints to the pseudo-Boolean problem has a linear computational cost in the hill climber.

GENETIC VARIATION, LOCAL ADAPTATION AND POPULATION STRUCTURE IN NORTH AMERICAN RED OAK SPECIES, QUERCUS RUBRA L. AND Q. ELLIPSOIDALIS E. J. HILL

Forest trees, like oaks, rely on high levels of genetic variation to adapt to varying environmental conditions. Thus, genetic variation and its distribution are important for the long-term survival and adaptability of oak populations. Climate change is projected to lead to increased drought and fire events as well as a northward migration of tree species, including oaks. Additionally, decline in oak regeneration has become increasingly concerning since it may lead to decreased gene flow and increased inbreeding levels. This will in turn lead to lowered levels of genetic diversity, negatively affecting the growth and survival of populations. At the same time, populations at the species’ distribution edge, like those in this study, could possess important stores of genetic diversity and adaptive potential, while also being vulnerable to climatic or anthropogenic changes. A survey of the level and distribution of genetic variation and identification of potentially adaptive genes is needed since adaptive genetic variation is essential for their long-term survival. Oaks possess a remarkable characteristic in that they maintain their species identity and specific environmental adaptations despite their propensity to hybridize. Thus, in the face of interspecific gene flow, some areas of the genome remain differentiated due to selection. This characteristic allows the study of local environmental adaptation through genetic variation analyses. Furthermore, using genic markers with known putative functions makes it possible to link those differentiated markers to potential adaptive traits (e.g., flowering time, drought stress tolerance). Demographic processes like gene flow and genetic drift also play an important role in how genes (including adaptive genes) are maintained or spread. These processes are influenced by disturbances, both natural and anthropogenic. An examination of how genetic variation is geographically distributed can display how these genetic processes and geographical disturbances influence genetic variation patterns. For example, the spatial clustering of closely related trees could promote inbreeding with associated negative effects (inbreeding depression), if gene flow is limited. In turn this can have negative consequences for a species’ ability to adapt to changing environmental conditions. In contrast, interspecific hybridization may also allow the transfer of genes between species that increase their adaptive potential in a changing environment. I have studied the ecologically divergent, interfertile red oaks, Quercus rubra and Q. ellipsoidalis, to identify genes with potential roles in adaptation to abiotic stress through traits such as drought tolerance and flowering time, and to assess the level and distribution of genetic variation. I found evidence for moderate gene flow between the two species and low interspecific genetic differences at most genetic markers (Lind and Gailing 2013). However, the screening of genic markers with potential roles in phenology and drought tolerance led to the identification of a CONSTANS-like (COL) gene, a candidate gene for flowering time and growth. This marker, located in the coding region of the gene, was highly differentiated between the two species in multiple geographical areas, despite interspecific gene flow, and may play a role in reproductive isolation and adaptive divergence between the two species (Lind-Riehl et al. 2014). Since climate change could result in a northward migration of trees species like oaks, this gene could be important in maintaining species identity despite increased contact zones between species (e.g., increased gene flow). Finally I examined differences in spatial genetic structure (SGS) and genetic variation between species and populations subjected to different management strategies and natural disturbances. Diverse management activities combined with various natural disturbances as well as species specific life history traits influenced SGS patterns and inbreeding levels (Lind-Riehl and Gailing submitted).

Book review: Laurel Kamada, Hybrid Identities and Adolescent Girls: Being Half in Japan. Bristol: Multilingual Matters, 2010

Arguably, the catalyst for the best research studies using social analysis of discourse is personal ‘lived’ experience. This is certainly the case for Kamada, who, as a white American woman with a Japanese spouse, had to deal first hand with the racialization of her son. Like many other mixed-ethnic parents, she experienced the shock and disap-pointment of finding her child being racialized as ‘Chinese’ in America through peer group taunts, and constituted as gaijin (a foreigner) in his own homeland of Japan. As a member of an e-list of the (Japan) Bilingualism Special Interest Group (BSIG), Kamada learnt that other parents from the English-speaking foreign community in Japan had similar disturbing stories to tell of their mixed-ethnic children who, upon entering the Japanese school system, were mocked, bullied and marginalized by their peers. She men-tions a pervasive Japanese proverb which warns of diversity or difference getting squashed: ‘The nail that sticks up gets hammered down’. This imperative to conform to Japanese behavioural and discursive norms prompted Kamada’s quest to investigate the impact of ‘otherization’ on the identities of children of mixed parentage. In this fascinat-ing book, she shows that this pressure to conform is balanced by a corresponding cele-bration of ‘hybrid’ or mixed identities. The children in her study are also able to negotiate their identities positively as they come to terms with contradictory discursive notions of ‘Japaneseness’, ‘whiteness’ and ‘halfness/doubleness’.The discursive construction of identity has become a central concern amongst researchers across a wide range of academic disciplines within the humanities and the social sciences, and most existing work either concentrates on a specific identity cate-gory, such as gender, sexuality or national identity, or else offers a broader discussion of how identity is theorized. Kamada’s book is refreshing because it crosses the usual boundaries and offers divergent insights on identity in a number of ways. First, using the term ‘ethno-gendering’, she examines the ways in which six mixed-ethnic girls living in Japan accomplish and manage the relationship between their gender and ethnic ‘differ-ences’ from age 12 to 15. She analyses in close detail how their actions or displays within certain situated interactions might come into conflict with how they are seen or constituted by others. Second, Kamada’s study builds on contemporary writing on the benefits of hybridity where identities are fluid, flexible and indeterminate, and which contest the usual monolithic distinctions of gender, ethnicity, class, etc. Here, Kamada carves out an original space for her findings. While scholars have often investigated changing identities and language practices of young people who have been geographi-cally displaced and are newcomers to the local language, Kamada’s participants were all born and brought up in Japan, were fluent in Japanese and were relatively proficient in English. Third, the author refuses to conceptualize or theorize identity from a single given viewpoint in preference to others, but in postmodernist spirit draws upon multiple perspectives and frameworks of discourse analysis in order to create different forms of knowledge and understandings of her subject. Drawing on this ‘multi-perspectival’ approach, Kamada examines grammatical, lexical, rhetorical and interactional features from six extensive conversations, to show how her participants position their diverse identities in relation to their friends, to the researcher and to the outside world. Kamada’s study is driven by three clear aims. The first is to find out ‘whether there are any tensions and dilemmas in the ways adolescent girls of Japanese and “white” mixed parentage in Japan identify themselves in terms of ethnicity’. In Chapter 4, she shows how the girls indeed felt that they stood out as different and consequently experienced isolation, marginalization and bullying at school – although they were able to make better sense of this as they grew older, repositioning the bullies as pitiable. The second aim is to ask how, if at all, her participants celebrate their ethnicity, and furthermore, what kind of symbolic, linguistic and social capital they were able to claim for themselves on the basis of their hybrid identities. In Chapter 5, Kamada shows how the girls over time were able to constitute themselves as insiders while constituting ‘the Japanese’ as outsiders, and their network of mixed-ethnic friends was a key means to achieve this. In Chapter 6, the author develops this potential celebration of the girls’ mixed ethnicity by investigating the privileges they perceived it afforded them – for example, having the advantage of pos-sessing English proficiency and intercultural ‘savvy’ in a globalized world. Kamada’s third aim is to ask how her participants positioned themselves and performed their hybrid identities on the basis of their constituted appearance: that is, how the girls saw them-selves based on how they looked to others. In Chapter 7, the author shows that, while there are competing discourses at work, the girls are able to take up empowering positions within a discourse of ‘foreigner attractiveness’ or ‘a white-Western female beauty’ discourse, which provides them with a certain cachet among their Japanese peers. Throughout the book, Kamada adopts a highly self-reflexive perspective of her own position as author. For example, she interrogates the fact that she may have changed the lived reality of her six participants during the course of her research study. As the six girls, who were ‘best friends’, lived in different parts of the Morita region of Japan, she had to be proactive in organizing six separate ‘get-togethers’ through the course of her three-year study. She acknowledges that she did not collect ‘naturally occurring data’ but rather co-constructed opportunities for the girls to meet and talk on a regular basis. At these meetings, she encouraged the girls to discuss matters of identity, prompted by open-ended interview questions, by stimulus materials such as photos, articles and pic-tures, and by individual tasks such as drawing self-portraits. By giving her participants a platform in this way, Kamada not only elicited some very rich spoken data but also ‘helped in some way to shape the attitudes and self-images of the girls positively, in ways that might not have developed had these get-togethers not occurred’ (p. 221). While the data she gathers are indeed rich, it may well be asked whether there is a mismatch between the girls’ frank and engaging accounts of personal experience, and the social constructionist academic register in which these are later re-articulated. When Kamada writes, ‘Rina related how within the more narrow range of discourses that she had to draw on in her past, she was disempowered and marginalized’ (p. 118), we know that Rina’s actual words were very different. Would she really recognize, understand and agree with the reported speech of the researcher? This small omission of self-reflexivity apart – an omission which is true of most lin-guistic ethnography conducted today – Kamada has written a unique, engaging and thought-provoking book which offers a model to future discourse analysts investigating hybrid identities. The idea that speakers can draw upon competing discourses or reper-toires to constitute their identities in contrasting, creative and positive ways provides linguistic researchers with a clear orientation by which to analyse the contradictions of identity construction as they occur across time in different discursive contexts
