Описание: A remarkable look at how the growth, technology, and politics of high-frequency trading have altered global financial marketsIn today's financial markets, trading floors on which brokers buy and sell shares face-to-face have increasingly been replaced by lightning-fast electronic systems that use algorithms to execute astounding volumes of transactions. Trading at the Speed of Light tells the story of this epic transformation. Donald MacKenzie shows how in the 1990s, in what were then the disreputable margins of the US financial system, a new approach to trading-automated high-frequency trading or HFT-began and then spread throughout the world.
HFT has brought new efficiency to global trading, but has also created an unrelenting race for speed, leading to a systematic, subterranean battle among HFT algorithms. In HFT, time is measured in nanoseconds (billionths of a second), and in a nanosecond the fastest possible signal-light in a vacuum-can travel only thirty centimeters, or roughly a foot. That makes HFT exquisitely sensitive to the length and transmission capacity of the cables connecting computer servers to the exchanges' systems and to the location of the microwave towers that carry signals between computer datacenters.
Drawing from more than 300 interviews with high-frequency traders, the people who supply them with technological and communication capabilities, exchange staff, regulators, and many others, MacKenzie reveals the extraordinary efforts expended to speed up every aspect of trading. He looks at how in some markets big banks have fought off the challenge from HFT firms, and how exchanges sometimes engineer technical systems to favor certain types of algorithms over others. Focusing on the material, political, and economic characteristics of high-frequency trading, Trading at the Speed of Light offers a unique glimpse into its influence on global finance and where it could lead us in the future.

Описание:
Good education changes lives. It is therefore unsurprising that improved schooling plays a central part in most development strategies. At the same time, the expansion of school attainment alone is not sufficient to guarantee improved welfare. This open access book focuses on one country in West Africa, Togo, to explore what a country that has successfully increased enrollment rates can do to enhance learning outcomes. The authors explore different avenues for improvement, including enhancing the efficiency with which resources are used; increasing the qualifications of teachers; and through greater community involvement in school management. There is scope for improvement along all these dimensions, yet changes at the margin are insufficient to bring about the transformation needed to bring about acceptable levels of learning.Important reading for anyone interested in understanding the pathways to improving the education system in Togo and other developing countries.

Описание: This volume provides new approaches to the concept of media logics – developed by Altheide and Snow – by drawing on theoretical and empirical perspectives from international scientists working in the field of communications, media, political science, and sociology. In an increasingly digitized and globalized world, powerful media structures and technologies influence our daily lives in many respects. It is not only mass media but ‘poly media channels’ that become more and more contextualized in everyday lives. Therefore, it is necessary to revisit the theory of media logics, which focuses on the strong intercorrelation of media technologies, media institutions and media power. Media Logic(s) Revisited attends to this by critically reflecting on the idea of media logic, a much needed input in light of current developments and strong cultural embedding of media in various social contexts.

In 1986, a group of young Brazilian women started a movement to secure economic rights for rural women and transform women's roles in their homes and communities. Together with activists across the country, they built a new democracy in the wake of a military dictatorship. In Sustaining Activism, Jeffrey W. Rubin and Emma Sokoloff-Rubin tell the behind-the-scenes story of this remarkable movement. As a father-daughter team, they describe the challenges of ethnographic research and the way their collaboration gave them a unique window into a fiery struggle for equality.
Starting in 2002, Rubin and Sokoloff-Rubin traveled together to southern Brazil, where they interviewed activists over the course of ten years. Their vivid descriptions of women’s lives reveal the hard work of sustaining a social movement in the years after initial victories, when the political way forward was no longer clear and the goal of remaking gender roles proved more difficult than activists had ever imagined. Highlighting the tensions within the movement about how best to effect change, Sustaining Activism ultimately shows that democracies need social movements in order to improve people’s lives and create a more just society.
