Did humans migrate to the new world from europe in early prehistoric times - Essay Example However, Curry cited that the discovery of the prehistoric and hypothetically pre-Clovis, mastodon fossils in Washington spur debate concerning the actual manner of human migration from Europe to America. Specifically, existing debates focus on the theories of Bradley and Stanford and Straus. In studying the fossils found both in Alaska and Siberia, Bradley and Stanford assert the existence of pre-Clovis culture in America (465). Further, with their radiocarbon fossil dating technologies, Bradley and Stanford unearthed evidences that link the fossils in pre-Clovis North America with the fossils of the Solutrean culture residing in Spain and France 17,000-21,000 years in the past (466). The fossils, particularly the hunting technologies, show significant similarities, regardless of the fact that the Clovis technology appears more advanced and a few radiocarbon years older than its Solutrean counterparts. Relatively, the Clovis culture may be considered predecessors of the Solutrean culture, considering the similarities of their hunting tools. With those findings, Bradley and Stanford went on to propose that Solutrean may have traveled from Europe to America through ice bridges near the Arctic, although remaining close to the coast to ensure sustainable, marine food source s. The proposition relies heavily on the existence of steppe tundra vegetations during the Last Glacial Maximum wherein ice formed as land bridges connecting the continents. Although Bradley and Stanford succeeded in nulling the theory supporting the Clovis culture as the first American inhabitants, Straus argues that the theory still lack evidences supporting the existence of Solutrean culture in North America before the Clovis culture. Specifically, in studying the drawings and artistic works in Cosquer Cave, Straus found out that the Solutrean culture was purged approximately 18,000 radiocarbon years ago (223). Further, Strauss asserts that the similarities in the

Comprehensive Exam - Research Paper Example Nature and Types of Theory In order to understand the nature and types of theory, five articles in the field of ‘virtual project management’ have been analyzed. Article 1: â€Å"Patterns for Effective Management of Virtual Projects: Theory and Evidence† This research was undertaken with the intention of understanding the forms for efficient management of virtual projects. The research uses a blend of theories and disciplines in order to recognize different perspectives on the research subject. It explores the theoretical foundation of project typologies. For instance, in this research, the researcher used ‘Media Richness Theory’, ‘Channel Expansion Theory’ and ‘Adaptive Structuration Theory’ in order to recognize the theoretical concept of virtuality. The research is based on ‘Pattern Theory’ in order to understand natural perspectives on effective methods in the field of virtual project management. Theory is use ful way in this research to develop a sense with respect to different factors which impact on the virtual project management. In order to explain the theory, the researcher has also used figures. The figures help to describe different patterns on the aspect of virtual project management. ... It discovers the combined impact of leadership, personality and organizational aspects on time, scope and quality of virtual projects. The research is based on the theoretical aspect of transformational leadership, personality and other substitute factors in order to measure their effects on virtual projects. A model has been used in order to demonstrate the impact of leadership on performance of virtual projects. In this research, the major concept is to measure the impact of leadership, personality, and other aspects on virtual team performance (Strang, 2010). Article 3: â€Å"Knowledge Integration in Virtual Teams: The Potential Role of KMS† This article explores difficulties of knowledge integration in virtual team context. The research is based on communication theory in order to recognize ‘Knowledge Management System’ (KMS) in different stages of virtual project management. The research concepts are operationalized by concentrating on virtual team circumstan ces where organizations try to utilize the knowledge oriented assets. In order to conduct the research, the researchers used secondary databases for describing how virtual teams can generate challenges towards application of knowledge oriented assets throughout virtual project phases (Alavi & Tiwana, 2002). Article 4: â€Å"Getting it Together: Temporal Coordination and Conflict Management in Global Virtual Teams† The research aims at investigating the impact of chronological management on virtual teams through asynchronous interaction. The research demonstrates an explicit theoretical framework on the aspect of chronological management challenges, interaction and management of conflict within a virtual team. In order to gather information theories on non-virtual teams have
