In lieu of an abstract, here is a brief excerpt of the content:Art in Social Studies: Exploring the World and Ourselves with RembrandtIftikhar Ahmad (bio)IntroductionRembrandt’s art lends itself as a fertile resource for teaching and learning social studies. His art not only captures the social studies themes relevant to the Dutch Golden Age, but it also offers a description of human relations transcending temporal and spatial frontiers. Rembrandt is an imaginative storyteller with a keen insight for minute details. His narrative (...) of the culture, society, economy, geography, and contemporary events of seventeenth-century Dutch life is as vivid and perceptive as a historian’s eloquent text. How people lived in community, how the city of Amsterdam functioned, how important religion was to people, how diverse and cosmopolitan the culture was, how interdependent the world was in the seventeenth century, and what the social and civic ideals of the Dutch people were during the Golden Age—Rembrandt’s paintings, etchings, and drawings neatly organize these and other social studies themes into visual messages. More importantly, our appreciation and interpretation of Rembrandt’s work helps us learn about not just Dutch society and culture of four hundred years ago but also about ourselves. The passion, emotions, conflicts, and inspirations of his subjects are essentially human and eternal, arousing empathy in every generation and cross-section of society. In this article I look at Rembrandt’s art for the purpose of teaching and learning social studies in our contemporary interdependent world—a world that is chronologically and geographically distant from the Dutch Golden Age but in many respects shares its enduring values, norms, ideals, pursuits, challenges, and possibilities. To do so, I employ a conceptual lens—the curriculum thematic strands of the National Council for the Social Studies (NCSS)—to examine Rembrandt’s art in order to explore life and make meaning of the story that is being told about the human condition, and to seek out its relevance to ourselves and [End Page 19] our world in the early twenty-first century. Although Rembrandt’s oeuvre is extensive, including the diverse genres of self-portraits, group portraits, drawings, etchings, landscapes, and religious themes, for our limited purpose I have selected only those works that, in my judgment, correspond with the following seven of the ten thematic curriculum strands of the NCSS:CultureTime, Continuity, and ChangePeople, Places, and EnvironmentIndividual Development and IdentityProduction, Distribution, and ConsumptionGlobal ConnectionsCivic Ideals and PracticesThese thematic curriculum strands are derived from the foundational disciplines of the social sciences and humanities such as anthropology, history, geography, sociology, political science, psychology, economics, philosophy, and law, but they are conceptually interrelated.1 For example, culture is a core concept in anthropology but it is also relevant to Time, Continuity, and Change, which is the main concept in the history discipline. Similarly, culture is relevant to the theme of People, Places, and Environment, which is the central focus of geography. More importantly, since social studies is about human experiences, there is a general consensus among the social studies educators that classroom teachers should draw content knowledge not just from the social sciences as mentioned here but from wide sources “to construct curricular experiences enabling students to actively relate new knowledge to existing understanding.”2 That is to say all fields of knowledge that are related to human civilization and that help in developing students’ skills in reflective thinking, decision making, and problem solving are relevant to social studies education. Those fields also include art. Rembrandt’s art is especially relevant because his themes are universal and the social, political, and economic contexts in which he created his work—globalization, individualism, and free enterprise—are more or less similar to our age.It needs to be mentioned that by looking at Rembrandt’s art from the social studies perspective it is not my intention to strip his work of its aesthetic scope and value. On the contrary, by looking at Rembrandt in the social studies classroom I seek to humanize social studies education itself. That [End Page 20] is to say I wish to step back from the conventional view of social studies to feel free from the bonds of traditionalism and discover, describe, analyze... (shrink)

The integration of cellular networks and vehicular networks is complex and heterogeneous. Synchronization among vehicles in heterogeneous vehicular clusters plays an important role in effective data sharing and the stability of the cluster. This synchronization depends on the smooth exchange of information between vehicles and remote servers over the Internet. The remote servers predict road traffic patterns by adopting deep learning methods to help drivers on the roads. At the same time, local data processing at the vehicular cluster level may (...) increase the capabilities of remote servers. However, global positioning system signal interruption, especially in the urban environment, plays a big part in the detritions of synchronization among the vehicles that lead to the instability of the cluster. Instability of connections is a major hurdle in developing cost-effective solutions for deriving assistance and route planning applications. To solve this problem, a self-localization scheme within the vehicular cluster is proposed. The proposed self-localization scheme handles GPS signal interruption to the vehicle within the cluster. A unique clustering criterion and a synchronization mechanism for sharing traffic information system data among multiple vehicles are developed. The developed scheme is simulated and compared with existing known approaches. The results show the better performance of our proposed scheme over others. (shrink)
