Drawing on the great progress in Talmudic scholarship over the last century, The Stabilization of Rabbinic Culture is both an introduction to a close reading of rabbinic literature and a demonstration of the development of rabbinic thought on education in the first centuries of the Common Era. In Roman Palestine and Sasanid Persia, a small group of approximately two thousand Jewish scholars and rabbis sustained a thriving national and educational culture. They procured loyalty to the national language and oversaw the retention of a national identity. This accomplishment was unique in the Roman Near East, and few physical artifacts remain. The scope of oral teaching, however, was vast and was committed to writing only in the high Middle Ages. The content of this oral tradition remains the staple of Jewish learning through modern times. Though oral learning was common in many ancient cultures, the Jewish approach has a different theoretical basis and different aims. Marc Hirshman explores the evolution and institutionalization of Jewish culture in both Babylonian and Palestinian sources. At its core, he argues, the Jewish cultural thrust in the first centuries of the Common Era was a sustained effort to preserve the language of its culture in its most pristine form. Hirshman traces and outlines the ideals and practices of rabbinic learning as presented in the relatively few extensive discussions of the subject in late antique rabbinic sources. The Stabilization of Rabbinic Culture is a pioneering attempt to characterize the unique approach to learning developed by the rabbinic leadership in late antiquity.
Explaining human cooperation in large groups of non-kin is a major challenge to both rational choice theory and the theory of evolution. Recent research suggests that group cooperation can be explained assuming that cooperators can punish non-cooperators or cheaters. The experimental evidence comes from economic games in which group members are informed about the behavior of all others and cheating occurs in full view. We demonstrate that under more realistic information conditions, where cheating is less obvious, punishment is ineffective in enforcing cooperation. Evidently, the explanatory power of punishment is constrained by the visibility of cheating.
The emergence of an ever-widening sphere of global public policy is a new reality in a world characterized by the blurring of boundaries between the national and the global; by flows of ideas, people, and commodities; and by new global risks and opportunities. In this context, this article explores the empirical puzzle of the sudden outbreak of reforms leading to central-bank independence. How can we best understand the outbreak of reforms in the 1990s? It is suggested here that the reforms were diffused in a contagious and uncoordinated manner in a global policy process that may best be captured by Kingdon’s policy stream model. We develop an agent-based model to evaluate the effects of three little-explored aspects of the diffusion process. These are (i) the likelihood of the outbreak of reform, (ii) the rate of adoption of the reform, and (iii) the time to outbreak. We find that the likelihood of outbreak depends on the saliency of a problem, in conjunction with the length of time that a problem has been on the public agenda. We also find that an increase in the size of the environment surveyed before a decision is made increases the rate of adoption but also the time to outbreak. The more global the information available for agents, the longer is the time to outbreak, but outbreaks unfold much faster.
With the discovery of large quantities of natural gas, the Qatari economy has experienced sustained economic growth. Similar to what has occurred in other Gulf states, a consequence of this economic boom is that the demand level for skilled and unskilled labor far outstrips that which Qatari nationals can provide. As a result, Qatar has imported foreign labor to the point where foreigners outnumber Qataris by almost seven to one. Moreover, the structure of the labor market — in particular, the system of generous and near-guaranteed public sector employment — diminishes incentives for Qataris to acquire valuable skills and to work in the private sector. The reliance on foreign laborers and the lack of skilled Qatari workers is widely seen by Qatar’s leaders as a serious threat to the nation’s economic autonomy and long-term economic viability. Thus a key challenge facing policymakers is to devise policies and reforms that will help develop a domestic workforce with the skills and incentives to work in the economy’s most important and competitive positions. Drawing on public data sources, this article provides a detailed quantitative assessment of the economic and demographic situation that underlies the current challenges and discusses several policy options that might be used to help overcome them.
Quantitatively estimating rainfall-runoff relations in extremely arid regions is a challenging task, mainly because of lack of in situ data. For the past 40 years, rain and floods have been monitored in the Nahal Yael catchment (0.5 km2) in southern Israel, providing a unique data set of runoff hydrographs and rainfall in a hyper-arid region. Here we present an exploratory study focusing on rainfall-runoff modeling issues for a small (0.05 km2) sub-catchment of Nahal Yael. The event-based model includes the computation of rainfall excess, hillslope and channel routing. Two model parameters of the infiltration process were found by calibration. A resampling methodology of calibration group composition is suggested to derive optimal model parameters and their uncertainty range. Log-based objective functions were found to be more robust and less sensitive than non-log functions to calibration group composition. The fit achieved between observed and computed runoff hydrographs for the calibration and validation events is considered good relative to other modeling studies in arid and semi-arid regions. The study indicates that, under the calibration scheme used, a lumped model performs better than a model representing the catchment division into three sub-catchments. In addition, the use of rain data from several gauges improves runoff prediction as compared to input from a single gauge. It was found that rainfall uncertainty dominates uncertainties in runoff prediction while parameter uncertainties have only a minor effect. ?? 2009 Elsevier B.V. All rights reserved.
