International Telemetering Conference Proceedings / October 25-28, 1993 / Riviera Hotel and Convention Center, Las Vegas, Nevada / This paper describes the Launcher Instrumentation and Data Acquisition System (LIDAS) that has been developed for real-time monitoring and simultaneous recording of a diverse set of data buses on a moving MLRS launcher. The launcher onboard instrumentation consists of a central Bus Data Conversion Module (BDCM) and several specialized, intelligent "break-in" boxes. The break-in boxes collect and tag the data by using the IRIG-B standard time-code, and transfer them to the BDCM using a unique asynchronous scheme. The BDCM is built around an Intel 80960CA processor board in a VME bus environment. It coordinates all the data traffic and also stores selected data to an onboard Flash ROM data storage unit. The data from different MLRS buses are combined into a 1 megabits per second RS4-22 serial stream and telemetered to a ground station, where the user interface is provided through an IBM PC/AT type computer with touch-screen controls. The developed PC software offers several data monitoring options with engineering-unit conversions and allows simultaneous recording on a hard-disk. Because of its interactive capabilities, the system is also well suited for personnel training.

International Telemetering Conference Proceedings / October 25-28, 1993 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Boeing's Test Data Retrieval System not only acts as an interface between the Airborne Data Acquisition System and a mainframe computer but also does batch mode processing of data at faster than real time. Analysis engineers request time intervals and measurements of interest. Time intervals and measurements requested are acquired from the flight tape, converted to first order engineering units, and output to 3480 data cartridge tape for post processing. This allows all test data to be stored and only the data of interest to be processed at any given time.

This thesis is a case study on the emergence of functional categories in bilingual first language acquisition. The investigation focuses on the transition from one-word to multiword utterances and the shaping of functional projections of Determiner, Agreement and Tense and their associated formal features. The empirical basis of this work is a corpus of thirty-nine videorecorded observations of Carlo, an English-Italian bilingual child, during free-play sessions with an adult. Data was collected separately for English and Italian for a period of fifteen months from when the child was 1;10 until he was 3;1, and was then transcribed in CHAT format. Four interrelated lines of enquiry inform the analysis presented here. The principal research question concerns the acquisitional strategies adopted by C. in these early stages of development in the two languages. A bilingual child is the closest one can get to a perfect matched pair where a number of variables such as socio-cognitive development, socio-economic status, parents' education, etc. are eliminated, and the two main variables to be investigated are the child's two input languages. This is an ideal situation in which the respective roles of general acquisitional strategies and language particular ones can be teased apart. An analysis of the emergence of the morphosyntactic correlates of Determiner, Agreement and Tense categories in English and Italian reveals a discrepancy between the two languages in the age of acquisition, rate of acquisition and in the language-specific strategies the child adopts. The observation of a significant difference in C.'s acquisitional strategies in English and Italian leads us to the second and third research questions: the way in which the emergence of functional categories differs between the two languages, and the reasons why this should be the case. The most obvious difference is the extent to which morphological correlates of functional categories emerge in the child's speech. In Italian, verbal and nominal morphology emerges earlier than in English and, at least in the nominal system, there is evidence that an Agreement category is part of the child's grammar. In English, verbal morphology is virtually non-existent by the end of the period of observation, and there is no substantial evidence that either Agreement or Tense are realised. Lexically-specific, item-based learning plays a substantial role in both languages, but in Italian there is some evidence that a number of grammatical contrasts are becoming productive by age 3;0, albeit some of them are still limited to a small number of lexical items. Two reasons were identified for the observed differences in the emergence of Determiner, Agreement and Tense in English and Italian: a typological reason, and an environmental reason. The former concerns the richness of Italian morphology, where grammatical contrasts are transparently marked both on nominal and verbal paradigms, as opposed to the relative poverty of English morphology where such contrasts correlate less obviously ans systematically with morphophonological markers. The latter reason concerns the very different input conditions in which C. is exposed to Italian and English: Italian is the home language spoken to him by his family and his babsysitters, while he is addressed in English by the staff at the nursery where one adult is in charge of several children and cannot engage in the one-to-one interaction which is typical of the dyadic situation in which C. finds himself at home. The differences observed in the lead-lag pattern between C.'s Italian and his English also provide sufficient evidence to address the fourth research question concerning the separate developement of the two languages. The analysis of the data did not reveal any systematic interferences from one language to the other. On the contrary there is evidence that C. is sensitive to the different morphosyntactic cues of his two input languages, and that he can treat the two as independent, self-contained problem spaces.

This thesis by publication presents a study on English adpositions (e.g. to, in, at, from, in frontof, through). It attempts to offer a solution to the following three outstanding problems, whichare presented in each of the three parts making up the thesis, preceded by a general introduction(chapter 1) and followed by the general conclusions (chapter 7). The first part includes chapter2, and discusses the problem of What is the relation between adpositions and the non-linguistic,visual content they represent. The second part includes chapters 3 and 4, and discusses theproblem ofwhat is a proper compositional theory of the Syntax and Semantics of adpositions.The third part includes chapters 5 and 6, and discusses the problem of what is the psychologicalreality of this theory, regarding adults and children’s data.The following three solutions are suggested. First, the relation between adpositions and theircorresponding visual information is an isomorphism: adpositions capture how we “see” possiblespatio-temporal relations between objects, at a flexible level of fine-grainedness. Second, aproper compositional treatment of adpositions treats each syntactic unit (in front, of ) as offeringa distinct semantic contribution, hence spelling out a restricted instance of a spatio-temporalpart-of relation. Third, this compositional treatment of adpositions can also stand as a theory ofon-line interpretation in adults and a theory of their acquisition in children.These three answers are couched within a single theoretical approach, that of Discourse Representation Theory, and offer a unified solution to three apparently distinct problems regardingspatial adpositions and their linguistic properties.

UA Open Access Publishing Fund / Background: Ethnobotanical knowledge continues to be important for treating illness in many rural communities, despite access to health care clinics and pharmaceuticals. However, access to health care clinics and other modern services can have an impact on the distribution of medical ethnobotanical knowledge. Many factors have been shown to be associated with distributions in this type of knowledge. The goal of the sub-analyses reported in this paper was to better understand the relationship between herbal remedy knowledge, and two such factors, age and social network position, among the Yucatec Maya in Tabi, Yucatan. Methods: The sample consisted of 116 Yucatec Maya adults. Cultural consensus analysis was used to measure variation in herbal remedy knowledge using competence scores, which is a measure of participant agreement within a domain. Social network analysis was used to measure individual position within a network using in-degree scores, based on the number of people who asked an individual about herbal remedies. Surveys were used to capture relevant personal attributes, including age. Results: Analysis revealed a significant positive correlation between age and the herbal medicine competence score for individuals 45 and under, and no relationship for individuals over 45. There was an insignificant relationship between in-degree and competence scores for individuals 50 and under and a significant positive correlation for those over 50. Conclusions: There are two possible mechanisms that could account for the differences between cohorts: 1) knowledge accumulation over time; and/or 2) the stunting of knowledge acquisition through delayed acquisition, competing treatment options, and changes in values. Primary ethnographic evidence suggests that both mechanisms may be at play in Tabi. Future studies using longitudinal or cross-site comparisons are necessary to determine the whether and how the second mechanism is influencing the different cohorts.

The thesis presents a theoretical framework for the preparation of a portfolio for the course Didaktická propedeutika pro studenty angliètiny na FF UK. This preparatory course in didactics should serve as an introduction to the subject for future teachers of English in secondary schools, whom it should equip with a basic level of understanding of the general principles of learning, language acquisition and language learning. The work presents a course syllabus and in its individual chapters it describes the theoretical background for each seminar. The themes introduced in the course are: theories of learning and their application to language teaching, language identity, theory and description of first and second language acquisition, learner variables (age, gender, aptitude, intelligence, motivation, affective filter, learning styles, multiple intelligences, learner beliefs, the role of brain and memory in language acquisition, methods of teaching foreign languages, interlanguage, linguistic errors, levels of proficiency, communication and learning strategies, learner autonomy, the theory of a good language learner and teacher. The thesis includes an appendix containing handouts for each seminar and a student evaluation form for the assessment of the quality of the seminar.

Approved for public release, distribution is unlimited / There is a growing movement throughout the Department of Defense (DoD) towards the implementation of Network Centric Warfare (NCW). In an effort to transition to NCW, the Navy has fielded many different technologies. One system exploiting new technologies in the Intelligence, Surveillance, and Reconnaissance (ISR) domain is the Joint Fires Network/Tactical Exploitation System-Navy (JFN/TES-N), which was developed from the Army Tactical Exploitation System, (TES-A). This system was developed rapidly and uniquely for fleet deployment in accordance with the interim acquisition guidance signed by the Honorable Paul Wolfowitz. This guidance authorized Evolutionary Acquisition following a Spiral Development process in lieu of the "traditional" cold war process described in the DoD 5000 series publications. Assuming that (JFN/TES-N) will be viewed as a successful acquisition, several Navy personnel have stated that it may become the model for future C4I (and other) system acquisitions. This thesis seeks to help develop that model. The objectives of this thesis are: ʺ To examine whether the TES-N acquisition process is an appropriate model of Evolutionary Acquisition following a Spiral Development. ʺ To identify and make recommendations for changes or improvements to the TES-N acquisition program, so it can be used as a more appropriate model for Evolutionary Acquisition following a Spiral Development. This thesis concludes that Evolutionary Acquisition following a Spiral Development shown with the JFN/TES-N system is an acquisition policy that is appropriate for programs of the same size and scope, but larger more complex programs will not have as much success. Yet, in order for the JFN/TES-N program and future programs using Evolutionary Acquisition following a Spiral Development to succeed, changes have to be made in policies such as budgetary submissions, test and evaluation, policy, process, and training. / Ensign, United States Navy
