The purpose of this case study was to examine the why the English language learners (ELLs) in the Beaufort County, South Carolina school system have been so successful. This school system has recently experienced a boom in its ESL student population, and this population has performed very well on standardized tests. This study used critical theory as its theoretical framework and examined why the students have been successful rather than marginalized in Beaufort County schools. This phenomenon was investigated using semi-structured interviews with the ESOL Coordinator for Beaufort County, 4 ESL-lead teachers, and 6 mainstream teachers.^ Data were collected using semi-structured interviews with Sarah Owen, the Beaufort County ESOL, Gifted and Talented, and World Languages coordinator. Based on the results of her interview, 4 themes emerged that were used for the semi-structured interviews with ESOL and mainstream teachers. The interviews centered on the themes of ESL policy, ESL leadership, and teacher training. The ESL and mainstream teacher interviews also revealed several subthemes that included teacher attitude, why Beaufort County has been successful with the ELLs, and the teachers' recommendations for other schools systems trying to successfully accommodate a large ESL student population in mainstream classrooms. ^ The findings from the teachers' interviews revealed that additional training for the teachers without ESL experience helped them become comfortable instructing ELLs. This training should be conducted by the ESOL teachers for those without ESOL certification or endorsement. As the teachers had more training, they had better attitudes about teaching ESOL students in their classes. Finally, those who utilized the additional ESOL training and ESOL accommodations saw better student achievement in their classes.^ Based on the finding of this study, the researcher proposed a model for other school systems to follow in order to replicate the success of Beaufort County's ELLs. The implications of this study focus on other schools systems and why ELLs are not obtaining the same level of success as those in Beaufort County's schools. Finally, recommendations for further research are provided.^

This article argues that sonic technologies, such as telephones, voice recorders and phonographs, alongside more (audio)visual ones such as flickering fluorescent lights, videos, and the television sets are crucial to the world of Twin Peaks, and constitute this world as both a communications network with portals to the unknown, and an accumulation of recordings of ghosted voices and entities, perhaps finding its ultimate expression in the backwards reprocessed speech in the Black Lodge. This lodge can be understood as a space in which there are nothing but recordings, albeit now on a cosmic, spiritual and demonic level. Using a media archaeological approach to these devices in the series, this paper will argue that they were already operating by a media archaeological logic, generating the world of Twin Peaks as a haunted archive of sonic and other mediations.

[Excerpt] In this chapter, we draw from both popular media and research support, along with anecdotal examples drawn from conversations accumulated as part of our own prior studies. Our goal is to present reminders that working hours are a personal life choice, even with external demands, but a choice that is influenced by elements of the individual’s working situation. The implications of a choice for long working hours are shown through use of two past “hard working” icons from popular media, one from the 1940s and one from the 1980s. Discussion continues into current time with an overview highlighting advances in technology that provide expanded work opportunities but, also, exacerbate tendencies toward work addiction.

The morphogen Sonic Hedgehog (SHH) plays a critical role in the development of different tissues. In the central nervous system, SHH is well known to contribute to the patterning of the spinal cord and separation of the brain hemispheres. In addition, it has recently been shown that SHH signaling also contributes to the patterning of the telencephalon and establishment of adult neurogenic niches. In this work, we investigated whether SHH signaling influences the behavior of neural progenitors isolated from the dorsal telencephalon, which generate excitatory neurons and macroglial cells in vitro. We observed that SHH increases proliferation of cortical progenitors and generation of astrocytes, whereas blocking SHH signaling with cyclopamine has opposite effects. In both cases, generation of neurons did not seem to be affected. However, cell survival was broadly affected by blockade of SHH signaling. SHH effects were related to three different cell phenomena: mode of cell division, cell cycle length and cell growth. Together, our data in vitro demonstrate that SHH signaling controls cell behaviors that are important for proliferation of cerebral cortex progenitors, as well as differentiation and survival of neurons and astroglial cells.

The availability of new underwater cameras and sub-aqua diving gear in the immediate post-war era opened up exciting possibilities for both narrative and documentary filmmakers. While the visual elements of this new world could now be more easily captured on film, the sound elements of the sub-aqua environment remained more elusive. What did, or should, this undersea world sound like? This article examines the use of sound in the sub-aqua scenes of both fictional and documentary films in the 1950s and asks questions about the methods used in the sonification of these worlds. Comparing the operation of underwater sound and human hearing with the production and post-production strategies used by filmmakers, I seek to identify the emergence of a sound convention and its implications for issues of cinematic realism. Central to this convention is the manipulation of sonic frequencies. The sound strategies adopted also raise questions about the malleability of viewer perspective and sound-image relationship in terms of a realist mode of address. Linked to this is the use of sound to enhance audience experience on an affective level. As well as underpinning cinematic realism, these new sound environments offered fresh experiences to audiences seeking new reasons to visit the cinema in an era of widening forms of entertainment.

Though the trend rarely receives attention, since the 1970s many American filmmakers have been taking sound and music tropes from children’s films, television shows, and other forms of media and incorporating those sounds into films intended for adult audiences. Initially, these references might seem like regressive attempts at targeting some nostalgic desire to relive childhood. However, this dissertation asserts that these children’s sounds are instead designed to reconnect audience members with the multi-faceted fantasies and coping mechanisms that once, through children’s media, helped these audience members manage life’s anxieties. Because sound is the sense that Western audiences most associate with emotion and memory, it offers audiences immediate connection with these barely conscious longings. The first chapter turns to children’s media itself and analyzes Disney’s 1950s forays into television. The chapter argues that by selectively repurposing the gentlest sonic devices from the studio’s films, television shows like Disneyland created the studio’s signature sentimental “Disney sound.” As a result, a generation of baby boomers like Steven Spielberg comes of age and longs to recreate that comforting sound world. The second chapter thus focuses on Spielberg, who incorporates Disney music in films like Close Encounters of the Third Kind (1977). Rather than recreate Disney’s sound world, Spielberg uses this music as a springboard into a new realm I refer to as “sublime refuge” - an acoustic haven that combines overpowering sublimity and soothing comfort into one fantastical experience. The second half of the dissertation pivots into more experimental children’s cartoons like Gerald McBoing-Boing (1951) - cartoons that embrace audio-visual dissonance in ways that soothe even as they create tension through a phenomenon I call “comfortable discord.” In the final chapter, director Wes Anderson reveals that these sonic tensions have just as much appeal to adults. In films like The Royal Tenenbaums (2001), Anderson demonstrates that comfortable discord can simultaneously provide a balm for anxiety and create an open-ended space that makes empathetic connections between characters possible. The dissertation closes with a call to rethink nostalgia, not as a romanticization of the past, but rather as a reconnection with forgotten affective channels.

The paper develops a Dynamic Stochastic General Equilibrium (DSGE) model, which assesses the macroeconomic and labor market effects derived from simulating a positive shock to the stochastic component of the mining-energy sector productivity. Calibrating the model for the Colombian economy, this shock generates a whole increase in formal wages and a raise in tax revenues, expanding total consumption of the household members. These facts increase non-tradable goods prices relative to tradable goods prices, then real exchange rate decreases (appreciation) and occurs a displacement of productive resources from the tradable (manufacturing) sector to the non-tradable sector, followed by an increase in formal GDP and formal job gains. This situation makes the formal sector to absorb workers from the informal sector through the non-tradable formal subsector, which causes informal GDP to go down. As a consequence, in the net consumption falls for informal workers, which leads some members of the household not to offer their labor force in the informal sector but instead they prefer to keep unemployed. Therefore, the final result on the labor market is a decrease in the number of informal workers, of which a part are in the formal sector and the rest are unemployed.
