Over the past two decades, advanced technologies and space missions have completely transformed our understanding of potential life beyond Earth. The resulting field, astrobiology, has become a multidisciplinary scientific discipline, encompassing many of the natural sciences and having implications for many areas of research. This book presents an introduction and overview of astrobiology. It deals with a wide range of fields, from the search for signs of life on planets in our solar system, to the discovery of exoplanets in distant solar systems and assessing the potential for life there. The book is based on the course of the same name that the author taught for more than two decades at the Hebrew University, and the course recorded on YouTube in the Cornerstones program , which has accumulated tens of thousands of views. The book is accessible not only to students of natural sciences, but to any reader who wants to learn about and understand the fascinating possibilities of life on other worlds.

Usury: Moneylending, Money and Society in Rabbinic Literature is a study of the moneylending norms in the early stratum of rabbinic literature. It shows how these norms use the language of legal formalism to construct a community of status-equals, into which rabbinic adherents can buy their entry by making the correct investment choices. Placing these norms in a broad historical and intercultural context, it is a fresh look at Jewish moneylending norms, the first in over 30 years.

Relations between the new state of Israel and the European Union in the first twenty years of the Community’s existence were a major policy issue given the background of the Holocaust and the way the new nation was established. This book focuses on Israel-European Community relations from 1957 to 1970 - from the signing of the Treaty of Rome (1957), which officially established the Common Market, to the conclusion of Israel’s Free Trade Agreement with the Community. It reveals a new and key facet of Israeli diplomacy during the country's infancy, joining the many studies concerning Israel's relations with the United States, France, Germany and Britain.

The articles compiled in this volume are studies by Jacob (Kobi) Metzer, which examine economic and political-economy issues in the Mandate era and the State of Israel. Most of the studies were originally published in scholarly journals and collected volumes in English. Their revision and publication in Hebrew under one volume is aimed at making them more accessible to the Israeli readership. The book consists of nine chapters, grouped into three parts. The first part includes four chapters that present the main socio-economic attributes of the Arab and Jewish populations during the Mandate period and examine them in broad comparative frameworks. The three chapters of the second part take up ethno-national aspects of land and settlement in Mandatory Palestine and Israel, and analyze them in comparative perspective. The third part deals with patterns of immigration and employment of Jews as individuals. It contains two chapters. One documents the socio-demographic profile of the immigrants to Palestine in the first decade of the British Mandate, and compares it with the international migration of the time. The other chapter examines comparatively the patterns of Jewish self-employment in the Diaspora and in Mandatory Palestine and Israel, from the early twentieth century onward.

Despite many decades of research, we seem to linger in a state of confusion regarding what leadership is and if or how it might be cultivated. The book offers a new perspective on leadership, whereby what defines leadership is not one’s position or successful conduct but action of a certain kind. More specifically, leadership is about realizing the human potential to think, create or act outside the boundaries of what is known and safe in order to serve the greater good. What distinguishes “acts of leadership” is that they take place in a sphere of ambiguity and uncertainty. As such, acts of leadership are essentially risky, bold and adventurous. Obstacles and opponents are to be expected and no measure of success can be guaranteed. By placing leadership in its unique sphere of action, we realize that widely accepted prescriptions for rational or sensible conduct do not apply and that relying on them may shut us down before we even begin. We further appreciate that such acts exemplify “action” in its deepest sense: what we choose to do as free individuals in an uncertain universe, and how we do it, is a self-defining act; it makes us who we are.

The spread of the Assyrian Empire over the entire Fertile Crescent in the second half of the 8th century BC introduced various forms of cooperation between the neighboring nomadic Arabs and the imperial authorities. The geographical conditions and resultant lifestyle of the Arabs facilitated a mutual dependence and delicate equilibrium between themselves and the Assyrian rulers, eager to capitalize on their unprecedented regional might. Henceforth, the Arabs appear as an organic component of the Fertile Crescent history rather than mere desert raiders.

Marx’s 1857 introduction to his Critique of Political Economy , which was not published in his lifetime, remains his only mature attempt to formulate the philosophical presuppositions of his economic research. Marx’s preface to the same work, published in 1859, contains a complementary philosophical discussion on the relations between economy and society. Their joint translation presents Hebrew readers with an accessible overview of the philosophical principles at the basis of Marx’s research.

In recent years, information technology has become a significant factor in public policy, whether as an area in which to pursue policy, as a tool for implementing policy, or as a reflection on the social environment in which policy is shaped. The aim of this edited collection of articles is to present to the academic and general public a vivid updated picture of the relationship between the spread of the use of various information technologies and the design and operation of public policy. This is the first book in Hebrew to shed light on the changes taking place in public policy in the 21st century as a result of new techno-social processes. The collection includes articles written by researchers from various fields of knowledge: communications, law, education, political science, and public policy. The diversity of knowledge bases, theoretical frameworks, and research methods allows for a comprehensive and complex discussion of the relationships between information technology and public policy. These relationships raise several key issues discussed in the articles included in the edited collection. The first issue is that information technologies are a new area of public policy, and as such, these technologies and their distribution create multiple challenges for the state as designer and regulator of its citizens' living environment. A second issue concerns the penetration of information technologies into the field of civic participation in policymaking and policy implementation. The wide distribution of social networks, as well as the assembly and analysis of big data are being used to reshape the civil participation environment. A third issue relates to the fact that information technologies are resources in their own right in democratic processes in general, and in policy design in particular. For example, significant parts of the public debate on a variety of policy topics take place through social networks, which are privately owned by Internet platforms. Additionally, access to social networks and advanced technological capabilities can be seen as an important resource for influencing policymaking processes.

The kibbutz is a social experiment in collective living that challenges traditional economic theory. By sharing all income and resources equally among its members, the kibbutz system created strong incentives to free ride or—as in the case of the most educated and skilled—to depart for the city. Yet for much of the twentieth century kibbutzim thrived, and kibbutz life was perceived as idyllic both by members and the outside world. In The Mystery of the Kibbutz , Ran Abramitzky blends economic perspectives with personal insights to examine how kibbutzim successfully maintained equal sharing for so long despite their inherent incentive problems. Weaving the story of his own family’s experiences as kibbutz members with extensive economic and historical data, Abramitzky sheds light on the idealism and historical circumstances that helped kibbutzim overcome their economic contradictions. He illuminates how the design of kibbutzim met the challenges of thriving as enclaves in a capitalist world and evaluates kibbutzim’s success at sustaining economic equality. By drawing on the stories of his pioneering grandmother who founded a kibbutz, his uncle who remained in a kibbutz his entire adult life, and his mother who was raised in and left the kibbutz, Abramitzky brings to life the rise and fall of the kibbutz movement. The lessons that The Mystery of the Kibbutz draws from this unique social experiment extend far beyond the kibbutz gates, serving as a guide to societies that strive to foster economic and social equality.

The book examines the ideological motivations behind the selection of representations for Israeli banknotes and coins. The research is based on the proceedings and correspondence of the Bank of Israel Banknotes and Coinage Planning Committee from its inception in 1955 to 2012. The study reveals the mechanisms in which the legal tender is exploited as an expression of banal nationalism, implementing national emblems in an unnoticed manner. Banal nationalism is one of three theoretical frameworks we adopted. The other two are the long history of the Jewish people in the territory which today is the State of Israel; and selective tradition as a means for designing a nation. The book comprises eight chapters: theoretical overview; analytical portrayal of the working methods of the Bank of Israel Banknotes and Coinage Planning Committee; a study of the first designed “Allegoric Figures Series” (1959); analysis of the selection of human figures; the construction of the state borders through an array of landscape images; the reflection of the shifting boundaries in the changing representations in Jerusalem; the selection of archaeological emblems as a proof for national continuity; and the symbolic role of flora as identification with the land.

Since the establishment of the state and until 1985, Israel’s capital market was mostly nationalized. The government controlled most of the financial activities, and the scarce private activity was shared by only a few institutions that lacked real competition. A long line of reforms that took place since 1985 and to this day revolutionized the banking structure, the capital market and the pension system: • The government reduced its involvement almost completely • The funding means of the business sector and of households expanded tremendously • International capital movements were liberalaized • Conflicts of interests were reduced and the competition amongst financial institutions was improved. The book is divided into 3 parts: The demand for investment in means of production and housing; the funding supply of these investments; and the financial institutions and their supervising system. Every chapter covers a description of a different aspect of the Israeli capital market before exploring the market failures that plagued it and the reforms that alleviated them. A special emphasis is dedicated to the importance of resisting the pressure of interest groups and to the lessons that need to be implemented in the tasks that still lay ahead.

Modern Investment Theory is the only book published in Hebrew on this central topic for students and practitioners of business and economy. The book opens with a review of the investment environment and the structure and institutions of the Israeli capital market, as well as a description of the assets traded in the equity, debt, and derivative markets. Since Israel is a small economy, its interactions with global financial markets is highlighted. The core concepts are presented by order of their evolution and contribution to the field: from rational and behavioral decision-making in states of risk, to Portfolio Theory, the CAPM, and advanced theoretical and empirical models, including five-factor models. Three chapters are devoted to fixed income pricing and risk, and two chapters address derivative assets and their pricing. Some of the chapters introduce for the first time in Hebrew financial crises and their impact on the real economy and on society, private capital, behavioral finance, and international finance. Many of the concepts of modern investment theory were developed by prominent researchers; some won Nobel or other prestigious prizes. To sixteen of these outstanding researchers, seven of whom are Israeli, I devote special boxes entitled "Figures from the Hall of Fame," highlighting their contribution to the field. Pedagogically, the book follows the American model where each chapter is accompanied by a Powerpoint presentation file, the chapter is briefly summarized, has a list of key terms, and between twenty to forty questions. Teachers can access all chapter solutions.
