Digital Protest and Activism in Public Education : Reactions to Neoliberal Restructuring in Israel
Digital protest and activism in reaction to the consequences of neoliberalism in public education have become a global phenomenon in the second decade of the 21st century, emerging in countries such as the US, UK, France, and Israel.Teachers, parents, and other stakeholders in education are increasingly using digital media in their protest and activism efforts, yet these efforts have hardly been investigated to date.This book addresses this gap and employs an empirical exploration of the way in which Internet-based protest activity concerning public education issues is constructed, mobilised, and carried out.In doing so it provides key insights for the study of educational politics in the digital age.It shows how digital media is used by teachers and parents to create a bottom-up politics, spanning a common divide in the study of education politics between the macro (policymaking) and the micro (school) levels.The authors propose a novel taxonomy of uses of social media by digital activists, and argue that Internet-based social mobilisations develop different patterns of use of social media, based on the lived experience of their members and potential supporters.Finally, the book situates the rise of digital activism in education within the neoliberal restructuring of national education systems and the rise of neoliberal discourse of competition, budget discipline, and measurable achievements.The authors highlight three cases of Internet-based mobilisations in Israel, in which teachers and parents successfully affected public education policy. By providing a case-study driven analysis of digital protest and activism in education, this book will prove an invaluable text for researchers, leaders and practitioners in the field of education policy and comparative education.

Can RGB LEDs replace grow LEDs?
RGB LEDs can provide red, green, and blue light, but they may not be as effective as dedicated grow LEDs for plant growth. Grow LEDs are designed to emit specific wavelengths of light that are most beneficial for plant photosynthesis and growth, such as red and blue light. While RGB LEDs can provide some of these wavelengths, they may not be as efficient or effective for promoting healthy plant growth. Therefore, it is recommended to use dedicated grow LEDs for indoor plant cultivation.

How can you convert 4-pin digital LEDs to 3-pin connectors?
To convert 4-pin digital LEDs to 3-pin connectors, you can use a simple adapter or converter cable. These cables typically have a 4-pin female connector on one end and a 3-pin male connector on the other end, allowing you to easily connect your 4-pin digital LEDs to a 3-pin header on your motherboard or controller. Alternatively, you can also manually rewire the 4-pin LED strip to a 3-pin connector by cutting and reconnecting the wires, ensuring that the positive, negative, and data wires are correctly aligned.
-
Can I connect LEDs?
Yes, you can connect LEDs to a power source using a resistor to limit the current flow and prevent the LEDs from burning out. Make sure to check the voltage and current requirements of the LEDs and use an appropriate power supply and resistor. You can also connect multiple LEDs in series or parallel to achieve the desired brightness and configuration. Always double-check the polarity of the LEDs and ensure proper connections to avoid damaging them.

Anonymity
Formally launched in 2014, ALA’s Center for the Future of Libraries works to identify emerging trends relevant to libraries and the communities they serve, promote futuring and innovation techniques to help librarians and library professionals shape their future, and build connections with experts and innovative thinkers to help libraries address emerging issues.The first volume in a new series presented in partnership with the Center, Anonymity explores the roles and ramifications of this hallmark of technology.In the virtual realm, anonymity means that such bedrock values of librarianship as privacy, free speech, and intellectual freedom coexist uneasily with the proliferation of fake news, sexist and racist sentiments, and repugnant ideologies.As trusted guardians of knowledge, libraries and librarians can fill a growing need for reputable information and open dialog.Macrina, founder and director of the Library Freedom Project and a core contributor to the Tor Project, along with co-author Cooper of The Intercept, discuss apps (Whisper, Secret) and forums (Reddit) that promote anonymity as a central feature, even as so-called true anonymity remains elusive because of pervasive user data tracking.They also examine how anonymous content has become valuable fodder for both news organizations and clickbait websites.Will the rise of anonymity and the vulnerabilities it exposes, especially for governments and businesses, lead to a movement against it? Or have our society and its technology passed the point of no return?Bringing issues and viewpoints from outside the profession into the conversation, this book will encourage libraries to think about anonymity and what it means for the future of our institutions.
