Merengue: Dominican Music and Identity

Merengue—the quintessential Dominican dance music—has a long and complex history, both on the island and in the large immigrant community in New York City. In this ambitious work, Paul Austerlitz unravels the African and Iberian roots of merengue and traces its growth under dictator Rafael Trujillo and its renewed popularity as an international music. Using extensive interviews as well as written commentaries, Austerlitz examines the historical and contemporary contexts in which merengue is performed and danced, its symbolic significance, its social functions, and its musical and choreographic structures. He tells the tale of merengue\u27s political functions, and of its class and racial significance. He not only explores the various ethnic origins of this Ibero-African art form, but points out how some Dominicans have tried to deny its African roots. In today\u27s global society, mass culture often marks ethnic identity. Found throughout Dominican society, both at home and abroad, merengue is the prime marker of Dominican identity. By telling the story of this dance music, the author captures the meaning of mass and folk expression in contemporary ethnicity as well as the relationship between regional, national, and migrant culture and between rural/regional and urban/mass culture. Austerlitz also traces the impact of migration and global culture on the native music, itself already a vibrant intermixture of home-grown merengue forms. From rural folk idiom to transnational mass music, merengue has had a long and colorful career. Its well-deserved popularity will make this book a must read for anyone interested in contemporary music; its complex history will make the book equally indispensable to anyone interested in cultural studies.https://cupola.gettysburg.edu/books/1124/thumbnail.jp

Machito and His Afro-Cubans: Selected Transcriptions

Machito (Francisco Raúl Grillo, 1909–1984) was born into a musical family in Havana, Cuba, and was already an experienced vocalist when he arrived in New York City in 1937. In 1940 he teamed up with his brother-in-law, the Cuban trumpeter Mario Bauzá (1911–1993), who had already made a name for himself with top African American swing bands such as those of Chick Webb and Cab Calloway. Together, Machito and Bauzá formed Machito and his Afro-Cubans. With Bauzá as musical director, the band forged vital pan-African connections by fusing Afro-Cuban rhythms with modern jazz and by collaborating with major figures in the bebop movement. Highly successful with Latino as well as black and white audiences, Machito and his Afro-Cubans recorded extensively and performed in dance halls, nightclubs, and on the concert stage. In this volume, ethnomusicologist Paul Austerlitz and bandleader and professor Jere Laukkanen (both experienced Latin jazz performers) present transcriptions from Machito’s recordings which meticulously illustrate the improvised as well as scored vocal, reed, brass, and percussion parts of the music. Austerlitz’s introductory essay traces the history of Afro-Cuban jazz in New York, a style that exerted a profound impact on leaders of the bebop movement, including Dizzy Gillespie and Charlie Parker, who appears as a guest soloist with Machito on some of the music transcribed here. This is MUSA’s first volume to represent the significant Latino heritage in North American music.https://cupola.gettysburg.edu/books/1106/thumbnail.jp

Neuronal Correlation Parameter in the Idea of Thermodynamic Entropy of an N-Body Gravitationally Bounded System

Understanding how the brain encodes information and performs computation requires statistical and functional analysis. Given the complexity of the human brain, simple methods that facilitate the interpretation of statistical correlations among different brain regions can be very useful. In this report we introduce a numerical correlation measure that may serve the interpretation of correlational neuronal data, and may assist in the evaluation of different brain states. The description of the dynamical brain system, through a global numerical measure may indicate the presence of an action principle which may facilitate a application of physics principles in the study of the human brain and cognition

An Experimental Study on the Heat Enhancement and the Bio-Heat Transfer Using Gold Macro Road and Ultrasound: A Potential Alternative to Kill Cancer Cells

We have previously proposed a method of treating solid tumors with a combination of gold macro-rods irradiated with ultrasound. Macro particle sized rods offer a greater circumferential treatment area over nanoparticle options. Experimental studies were conducted to investigate the heat enhancement and the bio-heat transfer to breast chicken using gold macro rod and ultrasound. An ultrasound, other than a focused ultrasound, may produce heat enough to cook a chicken breast up to about 1 cm diameter if a single gold rod is placed on the superficial tissue. Simulations and experimental results will provide the means to evaluate the treatment, to better design a patient-specific therapy to achieve maximum destruction of tumor and injury minimization of healthy tissue by controlling size, shape and location of gold seeds and ultrasound parameters

Gene surfing

Spatially resolved genetic data is increasingly used to reconstruct the migrational history of species. To assist such inference, we study, by means of simulations and analytical methods, the dynamics of neutral gene frequencies in a population undergoing a continual range expansion in one dimension. During such a colonization period, lineages can fix at the wave front by means of a ``surfing'' mechanism [Edmonds C.A., Lillie A.S. & Cavalli-Sforza L.L. (2004) Proc Natl Acad Sci USA 101: 975-979]. We quantify this phenomenon in terms of (i) the spatial distribution of lineages that reach fixation and, closely related, (ii) the continual loss of genetic diversity (heterozygosity) at the wave front, characterizing the approach to fixation. Our simulations show that an effective population size can be assigned to the wave that controls the (observable) gradient in heterozygosity left behind the colonization process. This effective population size is markedly higher in pushed waves than in pulled waves, and increases only sub-linearly with deme size. To explain these and other findings, we develop a versatile analytical approach, based on the physics of reaction-diffusion systems, that yields simple predictions for any deterministic population dynamics

Making judgements about students making work : lecturers’ assessment practices in art and design.

This research study explores the assessment practices in two higher education art and design departments. The key aim of this research was to explore art and design studio assessment practices as lived by and experienced by art and design lecturers. This work draws on two bodies of pre existing research. Firstly this study adopted innovative methodological approaches that have been employed to good effect to explore assessment in text based subjects (think aloud) and moderation mark agreement (observation). Secondly the study builds on existing research into the assessment of creative practice. By applying thinking aloud methodologies into a creative practice assessment context the authors seek to illuminate the ‘in practice’ rather than espoused assessment approaches adopted. The analysis suggests that lecturers in the study employed three macro conceptions of quality to support the judgement process. These were; the demonstration of significant learning over time, the demonstration of effective studentship and the presentation of meaningful art/design work

Enhanced response of the fricke solution doped with hematoporphyrin under X-rays irradiation

The vials filled with Fricke solutions were doped with increasing concentrations of Photogem®, used in photodynamic therapy. These vials were then irradiated with low-energy X-rays with doses ranging from 5 to 20 Gy. The conventional Fricke solution was also irradiated with the same doses. The concentration of ferric ions for the Fricke and doped-Fricke irradiated solutions were measured in a spectrophotometer at 220 to 340 nm. The results showed that there was an enhancement in the response of the doped-Fricke solution, which was proportional to the concentration of the photosensitizer. The use of such procedure for studying the radiosensitizing property of photosensitizers based on the production of free radicals is also discussed.Tubos de ensaio foram preenchidos com a solução Fricke dopada com Fotogem® em concentrações crescentes; essa hemotoporfirina é utilizada na terapia fotodinâmica. Esses tubos foram irradiados com doses de 5 a 20 Gy. A solução Fricke convencional também foi irradiada com as mesmas doses. As concentrações de íons férricos nas soluções Fricke convencional e dopadas irradiadas foram medidas num espectrofotômetro com comprimento de onda entre 220 e 340 nm. Os resultados mostraram que quando comparado o Fricke convencional com o Fricke dopado irradiado, as amostras dopadas demonstraram um aumento na resposta da dose absorvida que é proporcional a concentração do Photogem® na solução Fricke. Concluímos que esse procedimento pode ser utilizado para propósitos de dosimetria na terapia com radiossensibilizadores

COMMUNITY COLLABORATION AND COMMUNICATION IN THE DESIGN STUDIO

Based on the authors teaching experience, this essay presents an example of how the traditional design studio might be modified so as to foster democratic participation and egalitarian communication between the participating students and instructors. Open communication in the studio is seen as the key to incorporating important values such as collaboration, community and respect for the every day environment into the studio\u27s hidden curriculum. The essay begins by discussing the potentials for and obstacles to meaningful communication in the studio. This discussion is followed by a description of a modified studio project that included continuous role-playing on the part of the students. The final discussion outlines and evaluates how these modifications enabled students to use previous knowledge and everyday language and permitted the discussion of topics not usually debated in the studio. The students, in their assumed roles, became critics, clients and members of a team of designers. Hence these changes influenced the distribution of power in the studio and the students gained more control over their learning experience

Good, bad or just good enough: representations of motherhood and the maternal role on the small screen

This article seeks to introduce the contemporary maternal experience and the ‘good’ mother myth as it exists within the media landscape before considering the ways in which the situation comedy in general and the new American comedy, Mom (2013– ) in particular have negotiated ideal images of home, hearth, family and motherhood

High genetic diversity at the extreme range edge: nucleotide variation at nuclear loci in Scots pine (Pinus sylvestris L.) in Scotland

Nucleotide polymorphism at 12 nuclear loci was studied in Scots pine populations across an environmental gradient in Scotland, to evaluate the impacts of demographic history and selection on genetic diversity. At eight loci, diversity patterns were compared between Scottish and continental European populations. At these loci, a similar level of diversity (θsil=~0.01) was found in Scottish vs mainland European populations, contrary to expectations for recent colonization, however, less rapid decay of linkage disequilibrium was observed in the former (ρ=0.0086±0.0009, ρ=0.0245±0.0022, respectively). Scottish populations also showed a deficit of rare nucleotide variants (multi-locus Tajima's D=0.316 vs D=−0.379) and differed significantly from mainland populations in allelic frequency and/or haplotype structure at several loci. Within Scotland, western populations showed slightly reduced nucleotide diversity (πtot=0.0068) compared with those from the south and east (0.0079 and 0.0083, respectively) and about three times higher recombination to diversity ratio (ρ/θ=0.71 vs 0.15 and 0.18, respectively). By comparison with results from coalescent simulations, the observed allelic frequency spectrum in the western populations was compatible with a relatively recent bottleneck (0.00175 × 4Ne generations) that reduced the population to about 2% of the present size. However, heterogeneity in the allelic frequency distribution among geographical regions in Scotland suggests that subsequent admixture of populations with different demographic histories may also have played a role
