Concentration Camps : A Global History
A global and comprehensive history of a modern institution of inhumanity. In popular perception concentration camps are synonymous with genocide and Nazi racial extermination.Yet concentration camps were and are a global phenomenon, not restricted to Nazi Germany, used at times even by democracies, with an astonishing range of functions. Drawing together a wide range of multi-lingual archival research and synthesising a broad secondary literature, Alan Kramer provides here a comprehensive history of concentration camps, charting their first establishment at the beginning of the twentieth century on the colonial periphery, through their most extreme and inhuman instances in the mid-twentieth century, to their continued use today.Concentration camps are shown to be a truly transnational phenomenon that emerged both simultaneously (within and between imperial spheres—Britain, Spain, the USA, and Germany around 1900), and diachronically (from then to the First World War, the Gulag, and Nazi camps).Such camps existed (and exist) under a variety of regimes, often concomitant with empire-building by revolutionary dictatorships, as sites of genocide, mass murder, and performative violence, but also as central elements of utopian schemes of social and racial transformation.Integrating the perspective of perpetrators and the victims and contextualising them within the historiography of other carceral institutions, the book will reshape the way we think about concentration camps as part of modern civilization, past and present.

What causes lack of concentration when learning?
Lack of concentration when learning can be caused by a variety of factors. These can include distractions in the environment, such as noise or visual stimuli, as well as internal factors like fatigue, stress, or hunger. Additionally, lack of interest or motivation in the subject matter can also lead to difficulty concentrating. Finally, underlying issues such as attention deficit disorders or anxiety can also contribute to a lack of concentration when learning.

How can one have more concentration while learning?
One can improve concentration while learning by creating a dedicated study environment free from distractions, setting specific goals and deadlines for each study session, taking regular breaks to prevent burnout, and practicing mindfulness techniques such as deep breathing or meditation to stay focused. Additionally, staying organized and breaking down complex topics into smaller, more manageable chunks can help improve concentration and retention of information. Lastly, incorporating regular exercise, proper nutrition, and sufficient sleep into one's routine can also enhance concentration and overall cognitive function.

How does hunger arise from high concentration and learning?
Hunger can arise from high concentration and learning due to the increased energy expenditure of the brain during these activities. When we are deeply focused on a task or learning new information, our brain requires more glucose and nutrients to function effectively. As a result, our body may signal hunger to replenish these energy stores. Additionally, the mental exertion of concentration and learning can also lead to stress, which can trigger hunger as a physiological response to alleviate the stress. Overall, the cognitive demands of concentration and learning can lead to increased energy needs, which may manifest as hunger.

Why are concentration camps actually called concentration camps?
Concentration camps are called so because they concentrate a large number of people in a confined area, often under harsh conditions. The term "concentration" refers to the act of bringing together or focusing a specific group of individuals in one place. These camps were historically used to detain and oppress specific groups of people, such as political dissidents, minorities, or prisoners of war, with the goal of controlling and monitoring them closely.

Participatory Culture, Community, and Play : Learning from Reddit
What does online community look like in the age of social networking?How do participatory culture platforms reflect both their designers’ intentions and the desires of their users?In this incisive and timely work, Adrienne L. Massanari discusses how culture is created and challenged on Reddit.com, the self-proclaimed «front page of the internet».Reddit enables the sharing of original and reposted content from around the web, and provides a platform for like-minded individuals to commune around topics of interest – everything from the joys of drinking beer in a shower (/r/showerbeer) to celebrating the pleasures of tidy penmanship (/r/penmanshipporn).Massanari’s ethnographic work provides a detailed examination of the contradictions that shape Reddit’s culture and how they reflect its role as an epicenter of geek culture.The book explores the ways in which community on Reddit is formed and solidified through play and humor, and the complex ways in which Redditors come together, which demonstrate a deep capacity for altruism and charitable giving, but can easily lapse into mob action.It also explores the community’s troubling gender and racial politics and how some Redditors are carving out their own space on the site to fight back.

How does the enzyme concentration affect the substrate concentration?
The enzyme concentration directly affects the rate of reaction by increasing the likelihood of collisions between the enzyme and substrate molecules. As the enzyme concentration increases, there are more active sites available to bind with the substrate molecules, leading to a faster rate of reaction. However, once all the active sites are occupied, further increases in enzyme concentration will not have a significant effect on the rate of reaction unless the substrate concentration is also increased. Therefore, the enzyme concentration and substrate concentration both play a crucial role in determining the rate of reaction.

What is the difference between concentration and ion concentration?
Concentration refers to the amount of a substance present in a given volume of solution, typically measured in moles per liter (M). It can refer to the amount of any substance, such as a solute or a solvent, in a solution. On the other hand, ion concentration specifically refers to the amount of ions present in a solution. This can be the concentration of a specific type of ion, such as the concentration of hydrogen ions (H+) in a solution. Therefore, while concentration is a more general term that can refer to any substance, ion concentration specifically refers to the amount of ions in a solution.

What is the difference between molar concentration and mass concentration?
Molar concentration is a measure of the amount of a substance in a given volume of solution, expressed in moles per liter (mol/L). Mass concentration, on the other hand, is a measure of the amount of a substance in a given volume of solution, expressed in grams per liter (g/L). Molar concentration takes into account the molecular weight of the substance, while mass concentration simply considers the mass of the substance present in the solution.

What is the difference between mass concentration and molar concentration?
Mass concentration refers to the amount of solute present in a given volume of solution, typically expressed in units such as grams per liter. On the other hand, molar concentration, also known as molarity, refers to the number of moles of solute present in a given volume of solution, typically expressed in units of moles per liter. In other words, mass concentration is based on the mass of the solute, while molar concentration is based on the number of moles of the solute.
