A language is so constructed that the speaker is able to draw out of its resources whatever he wishes to communicate, yet whenever cultural borrowing occurs he cannot altogether avoid borrowing the words which are associated with it. Russian written records indicate that the language has been exposed to numerous foreign influences from very early times. With the intense introduction of "Westernization" since the sixteenth-century both English and French have had a considerable influence on Russian and especially in the twentieth-century this has even increased. For the purpose of this study, therefore, the writer has chosen to analyse English and French loanwords that are found in use in present-day Russian; examples from other languages, especially German, will be given occasionally insofar as they support the arguments presented. This thesis attempts an overall description of the morphological assimilation of loanwords. Phonological analysis and discussion of the socio-cultural context is given consideration in order to enable the reader and the analyst to see this paper as a whole. It was necessary to abstract linguistic elements at different levels of analysis so that some problems that are not explainable at the morphological level, would not be left unsolved. To some extent future borrowings into the Russian language in connection with cultural borrowing may be predicted. The pronounciation of a loanword depends on the degree of assimilation and whether or not the speaker is aware of the fact that it is a borrowing or wants to alert the listener as well. On the whole, loanwords are subject to phonological as well as morphological adjustments. Loanwords are sometimes under the pressure of both the native and foreign morphological systems, which in turn causes fluctuation of forms. Important external factors in the assimilation of loanwords at both levels are the audio and visual means of communication involved in transferring a loanword from either English or French into Russian. An interesting feature for future investigation is the analysis of loanwords on the lexical level and the correlation of lexical patterning with morphology in the process of loanword assimilation. / Arts, Faculty of / Central Eastern Northern European Studies, Department of / Graduate

Background: Since the 1940s, measures of pure-tone sensitivity and speech recognition in quiet have been vital components of the audiologic evaluation. Although early investigators urged that speech recognition in noise also should be a component of the audiologic evaluation, only recently has this suggestion started to become a reality. This report focuses on the Words-in-Noise (WIN) Test, which evaluates word recognition in multitalker babble at seven signal-to-noise ratios and uses the 50% correct point (in dB SNR) calculated with the Spearman-Kärber equation as the primary metric. The WIN was developed and validated in a series of 12 laboratory studies. The current study examined the effectiveness of the WIN materials for measuring the word-recognition performance of patients in a typical clinical setting. Purpose: To examine the relations among three audiometric measures including pure-tone thresholds, word-recognition performances in quiet, and word-recognition performances in multitalker babble for veterans seeking remediation for their hearing loss. Research Design: Retrospective, descriptive. Study Sample: The participants were 3430 veterans who for the most part were evaluated consecutively in the Audiology Clinic at the VA Medical Center, Mountain Home, Tennessee. The mean age was 62.3 yr (SD = 12.8 yr). Data Collection and Analysis: The data were collected in the course of a 60 min routine audiologic evaluation. A history, otoscopy, and aural-acoustic immittance measures also were included in the clinic protocol but were not evaluated in this report. Results: Overall, the 1000-8000 Hz thresholds were significantly lower (better) in the right ear (RE) than in the left ear (LE). There was a direct relation between age and the pure-tone thresholds, with greater change across age in the high frequencies than in the low frequencies. Notched audiograms at 4000 Hz were observed in at least one ear in 41% of the participants with more unilateral than bilateral notches. Normal pure-tone thresholds (≤20 dB HL) were obtained from 6% of the participants. Maximum performance on the Northwestern University Auditory Test No. 6 (NU-6) in quiet was ≥90% correct by 50% of the participants, with an additional 20% performing at ≥80% correct; the RE performed 1-3% better than the LE. Of the 3291 who completed the WIN on both ears, only 7% exhibited normal performance (50% correct point of ≤6 dB SNR). Overall, WIN performance was significantly better in the RE (mean = 13.3 dB SNR) than in the LE (mean = 13.8 dB SNR). Recognition performance on both the NU-6 and the WIN decreased as a function of both pure-tone hearing loss and age. There was a stronger relation between the high-frequency pure-tone average (1000, 2000, and 4000 Hz) and the WIN than between the pure-tone average (500, 1000, and 2000 Hz) and the WIN. Conclusions: The results on the WIN from both the previous laboratory studies and the current clinical study indicate that the WIN is an appropriate clinic instrument to assess word-recognition performance in background noise. Recognition performance on a speech-in-quiet task does not predict performance on a speech-in-noise task, as the two tasks reflect different domains of auditory function. Experience with the WIN indicates that word-in-noise tasks should be considered the "stress test" for auditory function.

摘要     “语言决定论”说明了语言和思想之间的联系，且通过分析语言与文化间的关系而不断改善。文化在一个人思想形成的基础阶段中发挥了决定性作用，是语言意识形态的基本特征。于是我们可以假设，文化价值作为一种可以衡量文化影响力的手段，文化影响力理应能够在文字中被识别出来和与文字建立起联系，而这也可与网络新词，这个从未被研究过的领域联系起来。     为了证明中国的文化价值对网络新词的影响，笔者会使用“定性内容分析”的方法与“定量分析法”。文化影响了字词的本意，也影响了在网络上出现的新词的意义。此外，中华文化价值与网络新词之间的联系不单可由文化对新词直接的影响中识别出来，亦可间接地在用法中加以识别。而有些网络新词虽然源于其他语言或文化，但是中国文化影响了这些网络新词的语境，使这些新词最终能够与中文融为一体。 / Linguistic determinism has prompted one of the earliest discussions about the connection between language and thought. This link has been further refined through the identification of cultural values playing a determinative role on the basic stage of thought formation, which is one of the fundamental aspects of language ideology. Such findings have sparked the hypothesis that cultural influences, in the form of cultural values as measurable means, should be recognized in or connected to words, even to those that belong to previously uninvestigated areas, such as new Internet words. The methodology of qualitative content analysis as well as a quantitative study applied to a sample of new Chinese Internet words and expressions has demonstrated that the influence of Chinese cultural values on them is identifiable to a significant extent. The cultural values either directly affect the words in their original or new meaning or have an influence on the Internet words indirectly, in their usage. Furthermore, it is argued that such connections between the researched Chinese cultural values and the meaning or usage of the collected new Chinese Internet words and expressions are not only to be strictly categorized into direct and indirect influences but should be considered in a broader sense. Despite some words and expressions originating from other languages and cultures, the influence of Chinese cultural values should still be acknowledged since it is through these that words are able to integrate into the Chinese language.

The grounding of language in humanoid robots is a fundamental problem, especially in social scenarios which involve the interaction of robots with human beings. Indeed, natural language represents the most natural interface for humans to interact and exchange information about concrete entities like KNIFE, HAMMER and abstract concepts such as MAKE, USE. This research domain is very important not only for the advances that it can produce in the design of human-robot communication systems, but also for the implication that it can have on cognitive science. Abstract words are used in daily conversations among people to describe events and situations that occur in the environment. Many scholars have suggested that the distinction between concrete and abstract words is a continuum according to which all entities can be varied in their level of abstractness. The work presented herein aimed to ground abstract concepts, similarly to concrete ones, in perception and action systems. This permitted to investigate how different behavioural and cognitive capabilities can be integrated in a humanoid robot in order to bootstrap the development of higher-order skills such as the acquisition of abstract words. To this end, three neuro-robotics models were implemented. The first neuro-robotics experiment consisted in training a humanoid robot to perform a set of motor primitives (e.g. PUSH, PULL, etc.) that hierarchically combined led to the acquisition of higher-order words (e.g. ACCEPT, REJECT). The implementation of this model, based on a feed-forward artificial neural networks, permitted the assessment of the training methodology adopted for the grounding of language in humanoid robots. In the second experiment, the architecture used for carrying out the first study was reimplemented employing recurrent artificial neural networks that enabled the temporal specification of the action primitives to be executed by the robot. This permitted to increase the combinations of actions that can be taught to the robot for the generation of more complex movements. For the third experiment, a model based on recurrent neural networks that integrated multi-modal inputs (i.e. language, vision and proprioception) was implemented for the grounding of abstract action words (e.g. USE, MAKE). Abstract representations of actions ("one-hot" encoding) used in the other two experiments, were replaced with the joints values recorded from the iCub robot sensors. Experimental results showed that motor primitives have different activation patterns according to the action's sequence in which they are embedded. Furthermore, the performed simulations suggested that the acquisition of concepts related to abstract action words requires the reactivation of similar internal representations activated during the acquisition of the basic concepts, directly grounded in perceptual and sensorimotor knowledge, contained in the hierarchical structure of the words used to ground the abstract action words.

The provision of public services has changed significantly over the years. One of the more recent changes has involved the increased delivery of public services by non-governmental organizations, whether these organizations be private in nature or belong to the so-called third sector. The third sector is known by a number of different terms, including the non-profit sector, the voluntary sector, civil society, and the social economy. Of particular interest in this study are those social economy organizations (SEOs) that receive the whole or a part of their revenue from the government. These organizations must be accountable to the government for the funds that government provides to them. The purpose of this accountability is to ensure SEOs undertake their obligations to use public resources effectively and to deliver quality public services. One potential accountability challenge involves the limitations associated with the performance evaluation of SEOs, since performance is often not easily observable. Performance is comprised of two parts: the work done by the organization (output) and the impact of this work (outcome). The difficulty in the observation of both outputs and outcomes may result in a conflict for the SEOs between focusing on observable parts of their work that can be more readily measured and reported to meet accountability requirements versus work with less tangible outputs and outcomes. In a funding agreement between an SEO and government, the SEO might have to agree with government requirements, for instance, to follow standardized procedures so that the government can monitor the observable aspects of its work. This requirement may conflict with the SEO’s desire to focus on things that are not observable, and consequently not funded by the government, but are important to the SEO’s mission and social goals. The goal of this research study is to examine the challenges that arise in the operation of SEOs, given that they need to be responsive to government’s expectations and at the same time follow their mission requirements. In-depth interviews were used to examine the extent to which outputs and outcomes are unobservable in SEOs as well as the possible conflicts that might arise between competing objectives within SEOs. Interview participants are three SEO executive directors and one manager, each of whom is responsible for the work carried out by his or her respective SEO. A government employee involved in providing funding to one of the SEOs was also interviewed. The results of this study suggest that the SEOs that were examined have varying degrees of unobservable outputs and outcomes. This study also found that organizations with a greater percentage of unobservable outputs and outcomes experienced a greater degree of conflict in their relationships with government. One of the reasons for the conflict is that the SEO personnel felt that the government focused its attention too much on the observable outputs/outcomes and not enough on outputs and outcomes that, although unobservable, were nevertheless important to clients and the public. Moreover, the SEOs examined in this study that serve specific groups of clients, such as seniors or immigrants, experienced less conflict than those whose services (e.g., increasing environmental sustainability) target the general public. The results of this research have implications for the way in which government structures its activities. Over the last 25-30 years, governments have, through New Public Management (NPM), privatized the provision of public services and encouraged greater competition in the delivery of public services. The results of the analysis carried out in this thesis suggest that this restructuring may not be as effective in situations where the services are directed toward the general public and/or where the services provided involve unobservable outputs and outcomes. The added conflict that appears to accompany these situations suggests that there may be goals and objectives that are important to society but are not being met through the contractual relationship established between the government and the SEO. Since NPM is expected to remain in place, government may wish to find ways of better addressing important unobservable outputs and outcomes. One suggestion, drawn from the interviews with SEOs, is that the government officials who are assigned to work with SEOs should have a good knowledge of the SEOs and be familiar with their missions and functions. This knowledge and familiarity might enable the government officials to evaluate the degree to which non-observable outputs and outcomes are being provided, which in turn might reduce conflict and ensure a better provision of services to clients and the public.

A morphism $\sigma$ is \emph{(strongly) unambiguous} with respect to a word $\alpha$ if there is no other morphism $\tau$ that maps $\alpha$ to the same image as $\sigma$. Moreover, $\sigma$ is said to be \emph{weakly unambiguous} with respect to a word $\alpha$ if $\sigma$ is the only \emph{nonerasing} morphism that can map $\alpha$ to $\sigma(\alpha)$, i.\,e., there does not exist any other nonerasing morphism $\tau$ satisfying $\tau(\alpha) = \sigma(\alpha)$. In the first main part of the present thesis, we wish to characterise those words with respect to which there exists a weakly unambiguous \emph{length-increasing} morphism that maps a word to an image that is strictly longer than the word. Our main result is a compact characterisation that holds for all morphisms with ternary or larger target alphabets. We also comprehensively describe those words that have a weakly unambiguous length-increasing morphism with a unary target alphabet, but we have to leave the problem open for binary alphabets, where we can merely give some non-characteristic conditions. \par The second main part of the present thesis studies the question of whether, for any given word, there exists a strongly unambiguous \emph{1-uniform} morphism, i.\,e., a morphism that maps every letter in the word to an image of length $1$. This problem shows some connections to previous research on \emph{fixed points} of nontrivial morphisms, i.\,e., those words $\alpha$ for which there is a morphism $\phi$ satisfying $\phi(\alpha) = \alpha$ and, for a symbol $x$ in $\alpha$, $\phi(x) \neq x$. Therefore, we can expand our examination of the existence of unambiguous morphisms to a discussion of the question of whether we can reduce the number of different symbols in a word that is not a fixed point such that the resulting word is again not a fixed point. This problem is quite similar to the setting of Billaud's Conjecture, the correctness of which we prove for a special case.

Content based video retrieval (CBVR) has been strongly motivated by a variety of realworld applications. Most state-of-the-art CBVR systems are built based on Bag-of-visual- Words (BovW) framework for visual resources representation and access. The framework, however, ignores spatial and temporal information contained in videos, which plays a fundamental role in unveiling semantic meanings. The information includes not only the spatial layout of visual content on a still frame (image), but also temporal changes across the sequential frames. Specially, spatially and temporally co-occurring visual words, which are extracted under the BovW framework, often tend to collaboratively represent objects, scenes, or events in the videos. The spatial and temporal information discovery would be useful to advance the CBVR technology. In this thesis, we propose to explore and analyse the spatial and temporal information from a new perspective: i) co-occurrence of the visual words is formulated as a correlation matrix, ii) spatial proximity and temporal coherence are analytically and empirically studied to re ne this correlation. Following this, a quantitative spatial and temporal correlation (STC) model is de ned. The STC discovered from either the query example (denoted by QC) or the data collection (denoted by DC) are assumed to determine speci- city of the visual words in the retrieval model, i:e: selected Words-Of-Interest are found more important for certain topics. Based on this hypothesis, we utilized the STC matrix to establish a novel visual content similarity measurement method and a query reformulation scheme for the retrieval model. Additionally, the STC also characterizes the context of the visual words, and accordingly a STC-Based context similarity measurement is proposed to detect the synonymous visual words. The method partially solves an inherent error of visual vocabulary under the BovW framework. Systematic experimental evaluations on public TRECVID and CC WEB VIDEO video collections demonstrate that the proposed methods based on the STC can substantially improve retrieval e ectiveness of the BovW framework. The retrieval model based on STC outperforms state-of-the-art CBVR methods on the data collections without storage and computational expense. Furthermore, the rebuilt visual vocabulary in this thesis is more compact and e ective. Above methods can be incorporated together for e ective and e cient CBVR system implementation. Based on the experimental results, it is concluded that the spatial-temporal correlation e ectively approximates the semantical correlation. This discovered correlation approximation can be utilized for both visual content representation and similarity measurement, which are key issues for CBVR technology development.
