Despite the differences among programs in total cost, procurement units, and technical objectives, DoD standardizes the weapon systems acquisition process via regularly updated directives (Ferrara 1996). Known as the Defense Acquisition Management System (DAMS), the formal process for the life cycle of a weapon system includes five phases and three milestone decisions (Department of Defense 2008). Given that each weapon system must adhere to the same policies and regulations, regardless of its scope or size, analysis across the entire DoD portfolio is feasible. In fact, research into the effectiveness of DoD weapon systems dates back to the 1950s (Marshall and Meckling 1959).
As part of the DAMS, weapon systems are required to publically release information regarding cost and schedule data via Selected Acquisition Reports and military budget requests. Cost and schedule data are tied to the development and production milestones outlined in DAMS. In contrast, performance data fr...

...t would measure the fulfillment of the knowledge points. GAO considered the fulfillment of each knowledge point to be analogous to the achievement of maturity for the weapon system. Technology maturity, as measured by Technology Readiness Levels (TRL), should be achieved by the program start to fulfill Knowledge Point #1 (GAO 1999). Design maturity, as measured by the number of releasable design drawings, should be achieved by the critical design review to fulfill Knowledge Point #2 (GAO 2002). Production maturity, as measured by the statistical control of critical manufacturing processes, should be achieved by the production start to fulfill Knowledge Point #3 (GAO 2002). Partly based on GAO recommendations, DoD has embraced the concept of weapon systems maturity within its acquisition guidance (Department of Defense 2008; Defense Acquisition University 2012).

- People have been interested for thousands of years in how babies seem to be so effortlessly and universally successful in learning their first language. After many years of research, linguists today believe that first language acquisition is the result of a complex set of factors which make unique contributions (and which undoubtedly operate interactively with each other). According to the latest research, perhaps the most important of these factors is the innate capacity all human brains have at birth to process language....

- very few terrorist organizations are highly motivated to detonate nuclear weapons of any kind to advance their objectives. The reason for this is the greatest challenge facing any terrorist group; the initial acquisition of a nuclear device (Ayson 2010, 573-574). The other challenge is the ability to create a weapon that can do the amount of damage hoped for. There are other points to consider, these include getting the right scientists to make the weapon, the cost of assembling the weapon and then transporting the assembled weapon safely to the site of the attack....

- The theory that had most impact on my understanding of the process of language acquisition, development and learning was the Acquisition/Learning Hypothesis. The Acquisition/Learning hypothesis was developed by Stephen Krashen. According to the textbook, he is a seminal researches in the innastis tradition, who developed five hypotheses about second language acquisition. All these hypotheses are relevant to educating English Language Learners and how they learn. The Acquisition/Learning hypothesis really made most sense to me and I was able to relate to it....

- Second Language Acquisition As globalization become more embedded in daily life, second language acquisition is considered as a necessary for people to be more engaged in the modern society. However, learning a second language is not an easy task. In order to acquire a second language in a more effective way, issues concerning the role of consciousness in foreign language learning have been raised. While there are general debates about the best way of learning a second language, I will advocate for the position that unconscious learning is taking place as a significant portion of second language acquisition....

- With the increasing popularity of dual immersion programs in schools and the widespread notion that language acquisition is something that needs to happen early on life, is there an ideal age to learn a second language (L2). Wilder Penfield and Lamar Roberts first introduced the idea that there is a “critical period” for learning language in 1959. This critical period is a biologically determined period referring to a period of time when learning/acquiring a language is relatively easy and typically meets with a high degree of success....

- Possessing a language is a quintessentially human trait, yet the acquisition of language in children is not perfectly understood. Most explanations involve the observation that children mimic what they hear and the assumption that human beings have a natural ability to understand grammar. Behaviorist B.F. Skinner originally proposed that language must be learned and cannot be a module. The mind consisted of sensorimotor abilities as well as laws of learning that govern gradual changes in an organism’s behavior (Skinner, B.F., 1957).... [tags: Chomsky, Language Acquisition]

- Language is perceived as the way humans communicate through the use of spoken words, it involves particular system and styles in which we interact with one another (Oxford 2009). Possessing this ability to communicate through the use of language is thought to be a quintessential human trait (Pinker 2000). Learning a language, know as language acquisition, is something that every child does successfully within a few years. Language acquisition is in itself the development by which humans acquire the ability to perceive, produce and use words to understand and communicate.... [tags: Language Acquisition]

- When I was in fourth grade a Jewish man visited my school to talk about his experiences during the Holocaust. However, his account of his time spent in the consecration camps was not what made my eyes to tear up that day. He related that when he was a young boy, he and his friends thought that in America money grew on trees. He said that growing up in Czechoslovakia he always dreamed of coming to America and living the "American dream." I could see the tears well up in his eyes and could hear the tremble in his voice when he began to tell us how lucky we were to be born in the USA because it "is the best country in the world." This was the first time when I realized how enormously blessed I... [tags: Immigrants Immigration USA]
