Training novel phonemic contrasts: a comparison of identification and oddity discrimination training

High Variability Pronunciation Training (HVPT) is a highly successful alternative to ASR-based pronunciation training. It has been demonstrated that HVPT is effective in teaching the perception of non-native phonemic contrasts, and that this skill generalizes to the perception of unfamiliar words and talkers, transfers to pronunciation, and is retained long-term. HVPT is, however, not efficient and hence not motivating for the learner. In this study, we therefore compare HVPT with an alternative, namely oddity discrimination training. This comparison, in which Mandarin-Chinese speakers were trained to pronounce the English /r/-/l/ phonemic contrast, provides preliminary evidence to support the use of discrimination tasks in addition to identification tasks to add variety to HVPT

Peace punks and punks against racism: resource mobilization and frame construction in the punk movement

In recent years, scholars have begun to attend to the gap in our understanding of the relationship between music and social movements. One such example is Corte’s and Edwards’ “White Power Music and the Mobilization of Racist Social Movements”. Our research shares the perspective of Corte and Edwards (2008) which emphasizes the centrality of music to social movement organizations, especially in terms of resource mobilization, but rather than look at how punk music was used as an instrument by an external social movement like the White Power movement, we look at how punks themselves joined social movements and altered the dynamics of the movements they joined. We also provide examples of punk involvement in left wing social movements to emphasize the indeterminate nature of punk politics. We examine two such cases: the Rock Against Racism movement in the U.K., and the Peace movement in the U.S. In both cases, punks made use of their independent media as a means to provide an infrastructure for mobilization of resources to sustain the punks’ involvement in these social movements and the unique framing provided by punks, which altered the dynamic of the movements they joined. What makes punk an interesting case is that the “do-it-yourself” ethic of independent media construction that was at the centre of the punk movement made it possible for punks to make connections to various other social movements as well as alter the dynamics of those social movements. In these cases, punk music was not used as a means toward an end, but rather punks themselves had a significant impact on these movements both in terms of resource mobilization and frame alignment

Computer support for cooperative tasks in Mission Operations Centers

Traditionally, spacecraft management has been performed by fixed teams of operators in Mission Operations Centers. The team cooperatively: (1) ensures that payload(s) on spacecraft perform their work; and (2) maintains the health and safety of the spacecraft through commanding and monitoring the spacecraft's subsystems. In the future, the task demands will increase and overload the operators. This paper describes the traditional spacecraft management environment and describes a new concept in which groupware will be used to create a Virtual Mission Operations Center. Groupware tools will be used to better utilize available resources through increased automation and dynamic sharing of personnel among missions

Feeling Low but Learning Faster: Effects of Emotion on Human Cognition

This study examined the effects of emotion on the long-term acquisition of a procedural skill over a five-day period. Two tasks were employed: a word association task (WAT) and a visual discrimination task (VDT). Over the initial four days of the study participants went through a mood induction procedure (MIP) then subsequently completed both tasks. Both tasks showed a reduction in reaction time consistent with the power law of learning. No significant change in reaction time between day four and day five (one week later) was noted suggesting the change in reaction time was robust. These data further suggest that emotion modifies the rate at which the VDT is acquired

The Virtual Mission Operations Center

Spacecraft management is becoming more human intensive as spacecraft become more complex and as operations costs are growing accordingly. Several automation approaches have been proposed to lower these costs. However, most of these approaches are not flexible enough in the operations processes and levels of automation that they support. This paper presents a concept called the Virtual Mission Operations Center (VMOC) that provides highly flexible support for dynamic spacecraft management processes and automation. In a VMOC, operations personnel can be shared among missions, the operations team can change personnel and their locations, and automation can be added and removed as appropriate. The VMOC employs a form of on-demand supervisory control called management by exception to free operators from having to actively monitor their system. The VMOC extends management by exception, however, so that distributed, dynamic teams can work together. The VMOC uses work-group computing concepts and groupware tools to provide a team infrastructure, and it employs user agents to allow operators to define and control system automation

Saving refugees or policing the seas? How the national press of five EU member states framed news coverage of the migration crisis

Migration from the Middle East and Africa to Europe increasingly hit the headlines in 2014-5 as the unprecedented scale of deaths at sea was gradually recognised as a newsworthy and important story. This article presents findings from research commissioned by UNHCR to measure how the issue of migration was framed in the news media across the EU. We compare the national press coverage of five member states: UK, Sweden, Germany, Spain and Italy, focusing upon the main themes of news coverage, reasons for and responses to migration outlined. We find striking variations in framing between national contexts, but also a significant disconnection, overall, between causal interpretation and treatment recommendation framing. We conclude that the resulting fragmented frames of European migration news in themselves signify ‘crisis’ - an unsettled discourse reflecting shifting anxieties between humanitarian concern to save refugees, and a securitising fortress mentality to better police European and national borders

Press coverage of the refugee and migrant crisis in the EU: a content analysis of five European countries

In 2014, more than 200,000 refugees and migrants fled for safety across the Mediterranean Sea. Crammed into overcrowded, unsafe boats, thousands drowned, prompting the Pope to warn that the sea was becoming a mass graveyard. The early months of 2015 saw no respite. In April alone more than 1,300 people drowned. This led to a large public outcry to increase rescue operations. Throughout this period, UNHCR and other humanitarian organisations, engaged in a series of largescale media advocacy exercises, aiming at convincing European countries to do more to help. It was crucial work, setting the tone for the dramatic rise in attention to the refugee crisis that followed in the second half of 2015. But the media was far from united in its response. While some outlets joined the call for more assistance, others were unsympathetic, arguing against increasing rescue operations. To learn why, UNHCR commissioned a report by the Cardiff School of Journalism to explore what was driving media coverage in five different European countries: Spain, Italy, Germany, the UK and Sweden. Researchers combed through thousands of articles written in 2014 and early 2015, revealing a number of important findings for future media advocacy campaigns. Most importantly, they found major differences between countries, in terms of the sources journalists used (domestic politicians, foreign politicians, citizens, or NGOs), the language they employed, the reasons they gave for the rise in refugee flows, and the solutions they suggested. Germany and Sweden, for example, overwhelmingly used the terms ‘refugee’ or ‘asylum seeker’, while Italy and the UK press preferred the word ‘migrant’. In Spain, the dominant term was ‘immigrant’. These terms had an important impact on the tenor of each country’s debate. Media also differed widely in terms of the predominant themes to their coverage. For instance, humanitarian themes were more common in Italian coverage than in British, German or Spanish press. Threat themes (such as to the welfare system, or cultural threats) were the most prevalent in Italy, Spain and Britain. Overall, the Swedish press was the most positive towards refugees and migrants, while coverage in the United Kingdom was the most negative, and the most polarised. Amongst those countries surveyed, Britain’s right-wing media was uniquely aggressively in its campaigns against refugees and migrants. This report provides important insights into each country’s press culture during a crucial period of agenda-setting for today’s refugee and migrant crisis. It also offers invaluable insights into historical trends. What emerges is a clear message that for media work on refugees, one size does not fit all. Effective media advocacy in different European nations requires targeted, tailored campaigns, which takes into account their unique cultures and political context
