Leakage Resilient Password Systems
This book investigates tradeoff between security and usability in designing leakage resilient password systems (LRP) and introduces two practical LRP systems named Cover Pad and ShadowKey. It demonstrates that existing LRP systems are subject to both brute force attacks and statistical attacks and that these attacks cannot be effectively mitigated without sacrificing the usability of LRP systems. Quantitative analysis proves that a secure LRP system in practical settings imposes a considerable amount of cognitive workload unless certain secure channels are involved. The book introduces a secure and practical LRP system, named Cover Pad, for password entry on touch-screen mobile devices. Cover Pad leverages a temporary secure channel between a user and a touch screen which can be easily realized by placing a hand shielding gesture on the touch screen. The temporary secure channel is used to deliver a hidden message to the user for transforming each password symbol before entering it on the touch screen. A user study shows the impact of these testing conditions on the users' performance in practice. Finally, this book introduces a new LRP system named ShadowKey. Shadow Key is designed to achieve better usability for leakage resilient password entry. It leverages either a permanent secure channel, which naturally exists between a user and the display unit of certain mobile devices, or a temporary secure channel, which can be easily realized between a user and a touch screen with a hand-shielding gesture. The secure channel protects the mappings between original password symbols and associated random symbols. Unlike previous LRP system users, Shadow Key users do not need to remember anything except their passwords. Leakage Resilient Password Systems is designed for professionals working in the security industry. Advanced-level students studying computer science and electrical engineering will find this brief full of useful material.

Power in Language, Culture, Literature and Education
In one of the contributions to this edited volume an interviewee argues that "English is power". For researchers in the field of English Studies this raises the questions of where the power of English resides and which types and practices of power are implied in the uses of English. Linguists, scholars of literature and culture, and language educators address aspects of these questions in a wide range of contributions. The book shows that the power of English can oscillate between empowerment and subjection, on the one hand enabling humans to develop manifold capabilities and on the other constraining their scope of action and reflection. In this edited volume, a case is made for self-critical English Studies to be dialogic, empowering and power-critical in approach.

What is leakage current, but no leakage voltage?
Leakage current is the flow of electric current through an insulating material, typically due to imperfections or defects in the material. This current can occur even when there is no applied voltage across the material. Leakage current can lead to energy loss, reduced efficiency, and potential safety hazards in electronic devices or systems. It is important to monitor and control leakage current to ensure the proper functioning and safety of electrical equipment.
-
What is the leakage current, but no leakage voltage?
Leakage current refers to the small amount of current that flows through an insulating material, such as a dielectric or semiconductor, when a voltage is applied across it. This can occur even when there is no external voltage source connected, and is due to the inherent properties of the material. On the other hand, leakage voltage refers to the voltage that is present across an insulating material due to the flow of current through it. Therefore, it is possible to have leakage current without leakage voltage, but not the other way around.

How can you prevent leakage?
To prevent leakage, you can take several measures such as regularly inspecting and maintaining your plumbing system, ensuring that all pipes and connections are properly sealed and in good condition. Additionally, you can use leak detection devices and sensors to monitor for any potential leaks and address them promptly. It's also important to be mindful of what you dispose of down your drains and toilets to prevent clogs and potential leaks. Finally, educating yourself and your household members about water conservation and responsible water usage can also help prevent leakage.

What is leakage current or induction?
Leakage current refers to the small amount of electric current that flows through an insulating material, such as the dielectric in a capacitor or the insulation of a wire. This current occurs due to imperfections in the insulating material or the presence of moisture or contaminants. Induction, on the other hand, refers to the generation of an electric current in a conductor due to a changing magnetic field. This phenomenon is the basis for the operation of transformers and inductors in electrical circuits. Both leakage current and induction can have implications for the performance and safety of electrical and electronic systems.

Delivering Citizenship
The 21st century promises to be an "Age of Mobility." More people around the globe, from an ever greater variety of backgrounds, are migrating. As Europe and North America absorb larger and more diverse inflows, many policymakers, commentators, and academics are questioning whether their societies can cope with the influx. Citizenship has emerged as one of the key policy battlegrounds for such concerns. Citizenship lies at the nexus of a host of social policy issues because it provides definitions of identity, belonging, and participation in key aspects of society, including the right to vote. Governments recognize the urgent need to understand citizenship better. Once a narrow, somewhat static legal backwater, citizenship has become a dynamic policy vehicle for promoting the political incorporation of immigrants and, by extension, their more complete integration. This book is the first major product of the Transatlantic Council on Migration. It offers insights into key aspects of the citizenship debate from a policy perspective. It is a result of the deliberations and thinking of the Transatlantic Council on Migration, which brings together leading political figures, policymakers and innovative thinkers from the USA and Europe. The Council is a new initiative of the Migration Policy Institute (MPI) in Washington, DC. The Bertelsmann Stiftung and the European Policy Centre (in cooperation with the King Baudouin Foundation) are the Council's policy partners.

Myśli nowoczesnego Polaka
"Od dawna już mam poczucie tego, że nasz systemat politycznego myślenia — o ile o takim może być mowa — w przeważnej mierze zbudowany jest na fałszach. W najważniejszych sprawach, w kwestjach dotyczących samej istoty naszego narodowego bytu, naszego stosunku do innych narodów i naszych widoków na samoistną przyszłość, polityczną i cywilizacyjną — zadawalniają nas zupełnie a nawet najlepiej nam smakują sądy, którym rzeczywistość zadaje kłam na każdym kroku. (...) Przez porównanie swego narodu z obcymi przekonałem się, że wiele z tych kłamstw naszą tylko myśl zatruwa, że niedorzeczności, które gdzieindziej powtarzane są tylko przez stare panny i w ogóle przez jednostki, żyjące po za społeczeństwem, odgrodzone od realnego życia, u nas stanowią podstawę myślenia ludzi poważnych, kierowników opinji i przodowników pracy publicznej, którzy na nich budują sądy dziejowe i nadzieje polityczne."

Are tampons or pads safer against leakage?
Both tampons and pads are designed to absorb menstrual flow and prevent leakage, but tampons are generally considered safer against leakage because they are inserted into the vaginal canal and directly absorb the flow. Pads, on the other hand, are worn externally and can sometimes shift or move, leading to potential leaks. However, the choice between tampons and pads ultimately depends on personal preference and comfort.
-
How do I measure the leakage current?
To measure leakage current, you can use a digital multimeter set to the milliampere (mA) range. First, ensure that the device or circuit you are testing is turned off. Then, connect the multimeter in series with the circuit or device, making sure the positive lead of the multimeter is connected to the positive terminal of the circuit and the negative lead to the negative terminal. Turn on the circuit and measure the current flowing through the multimeter. This reading will give you the leakage current of the circuit or device.
-
Are tampons or pads safer from leakage?
Both tampons and pads are designed to absorb menstrual flow and prevent leakage. However, some people may find that tampons are less likely to leak compared to pads, especially when engaging in physical activities like swimming or exercising. It ultimately depends on personal preference and comfort level, as both products can be effective in preventing leakage when used correctly.

How can one check for gas leakage?
One can check for gas leakage by using a gas leak detector, which is a handheld device that can detect the presence of gas in the air. Another method is to use a soapy water solution and apply it to the gas pipes or connections. If bubbles form, it indicates a gas leak. Additionally, one can listen for any hissing or whistling sounds near gas appliances or pipes, which could also indicate a gas leak.
