This study investigates the acquisition of Chinese connectives by second language learners under the theoretical framework of usage-based theory. Language is not a random set of words and phrases, but rather a coherent and cohesive set of utterances. As such, learning a second language (L2) entails, among other processes, learners’ development of employing cohesive devices to construct a coherent discourse in their target language. One type of cohesive devices frequently used by L2 learners is connectives. In Chinese, connectives are utilized to denote various semantic relationships between the clauses in a compound sentence. Due to their flexibility and complexity in nature, Chinese connectives present a huge challenge to L2 learners’ learning. However, to date no study has been set up to explore the learners’ development of Chinese connectives within L2 Chinese research community. This study aims to fill this gap in the literature and build an L2 acquisitional model of Chinese connectives under the theoretical framework of Constructionist Usage-based Theory. Constructionist Usage-based Theory maintains that the basic unit of language is constructions and that the syntactic and lexical form of constructions and its corresponding semantic and discourse functions are conventionalized in language usage. According to these notions, language learning is believed to be driven by the factors grounded in the form and function of constructions in language usage. This study specifically examines how the factors of frequency, form, function, contingency (interaction of form and function), and L1-tuned attention affect L2 Chinese learners’ development of Chinese connectives. Furthermore, the study investigates the learners’ knowledge about the distribution of Chinese connectives across different proficiency levels. Specifically, this study aims to address four research questions: (1) what is the relationship between L2 learners’ proficiency level and language background and the acquisition of Chinese connectives?; (2) do L2 learners overuse or underuse Chinese connectives in constructing responses when the other in a pair is given and what errors do L2 learners make when using Chinese connectives?; (3) how can 12 target pairs of Chinese connectives be categorized into (hierarchical) groups based on L2 Chinese learners’ performance?; and (4) how do theoretically-motivated models represent the factorial structure underlying L2 acquisition of Chinese connectives? To address the four research questions, this study elicited L2 Chinese learners’ performance in two tests: a mini-discourse completion test and a form-function association test. In the mini-discourse completion test, learners were required to supply a missing clause to complete a three-clause discourse in which one of paired connectives was embedded; in the form-function association test, learners were asked to choose options of paired connectives to link two given clauses where connectives were omitted. Results showed that the development of all Chinese paired connectives was positively correlated to L2 learners’ L2 proficiency level. Learners with heritage language background seemed to have an advantage over less frequent and less prototypical connectives. Predominantly, L2 learners underused Chinese connectives, resulting from the cross-linguistic influence of disparity between English and Chinese connectives at the structural level in particular and between English and Chinese textual cohesion at the discourse level in general. Based on L2 learners’ performances in the two tests, the 12 pairs of Chinese connectives were classifier into four hierarchical groups. Confirmatory factor analyses showed that the usage-based factors (i.e., frequency, co-occurrence strength, formulaicity, prototypicality, contingency, and L1-tuned attention) jointly determined the L2 acquisition and development of Chinese connectives in a complex, adaptive, dynamic manner. Summarizing these findings, this study proposed a usage-based acquisitional model of L2 Chinese connectives, providing theoretical contributions to the usage-based theory and pedagogical implications for Chinese connectives.

This thesis is about how aluminium correlates to democratic design. It includes comparisons between different materials used at a company that develops products according to democratic design. The analysis of how aluminium correlates is done in order to identify if the company has used and are using aluminium in the correct way, in a home environment. This report also includes some examples of analysis of product types, to show which would and whish would not benefit from being made out of aluminium.

ReadNPlay for a Bright Future develops a variety of projects aimed at promoting healthy living in families with young children in Northeast Tennessee. The purposes of this research are: (1) to collect parents’ and caregivers’ perspectives on healthy eating for the purpose of designing a new book in the ReadNPlay children’s book series to be entitled A Farmers Market Adventure (2) to collect the preferences of parents and guardians related to website and mobile application (app) usage to help shape the development of a new ReadNPlay My Baby Book app. Anonymous clipboard surveys were administered to attendees of regional community events during July of 2013. Survey items asked parents about healthy eating in the context of their families and the role of parenting websites and mobile apps in their families. The results from these surveys were summarized using Excel. A total of 100 surveys were collected. It was found that when parents were asked to identify barriers to healthy eating, the most common responses were picky eaters in the household (30%) followed by lack of time (22%). When asked to identify things that have helped parents to encourage healthy eating in their families, the three most common responses were good recipes (20%), good role models (16%), and farmers markets (16%). Twenty-eight percent of parents surveyed do not use websites or apps for parenting, while those who do use parenting websites or apps identified advice from experts (20%) and advice from other parents (18%) to be the two features most commonly desired in such a resource. When asked what they do not like about website and app usage, 20% of parents indicated that these tools are “too complicated.” However, when parents are told that our group of pediatricians was developing a free mobile application for families designed to help them keep track of their baby’s growth, development, and eating habits, 75% of parents said such an app would be very helpful to them (25% said a little helpful). These results will inform a new ReadNPlay children’s book themed around healthy eating behaviors, overcoming pickiness, and shopping with families at farmers markets and a new ReadNPlay mobile app for families to be use in conjunction with infant-toddler well child visits.

The purpose of this study is to identify the barriers to and facilitators of mental health services utilization among youth in the justice setting, and to explore ways to overcome these barriers and expand these facilitators. This qualitative study utilized focus groups as a means to extract themes among the perceptions of social workers on this topic. Results were transcribed to written form. Qualitative analysis procedures were followed to identify and label themes. A total of 473 statements are organized into 26 major themes with 18 sub‑themes. Suggestions for change under the agency/organizational category of domain three received the most overall discussion with 108 statements in all. The most discussed topics in the focus groups are quality of or improvements to services, which receives a total of 114 statements total, and punitive systems of care, which receives a total of 60 statements in all. Major suggestions for change made by participants include education and outreach for the public on mental health for juveniles, training on interventions and cultural competence for providers, and a shift from punitive to restorative for systems that justice youth interact with, to include schools, courts, probation, and law enforcement.

This study examines style shift between formal and informal styles in first- encounter conversations between Japanese native speakers and demonstrates how the speakers shifted the speech style in the context. Many researchers have studied this type of style shift and demonstrated that style shifts occur within a single speech context where social factors, such as differences in age, status, and formalness remain constant (e.g., Cook, 2008; Geyer, 2008; Ikuta, 1983; Maynard, 1991; Okamoto, 1999). This study contributed support to these previous studies. In this study, both quantitative and qualitative analyses focusing on Japanese native speakers' use of style shifting in first-encounter conversations were conducted. The data came from four dyadic first-encounter conversations between Japanese female speakers. The conversations were audio-recorded in a room where the researcher was not present. After recording the four conversations, the researcher conducted follow-up interviews in person or by phone in order to check the validity of my analysis collected for this study. Overall, all the speakers shifted between formal and informal styles at least ten times, indicating that they did not speak exclusively in one style or the other in the current data. The frequency of style shifts varied depending on the speakers, but in each conversation, the older partners of the pairs shifted their speech style more frequently than the younger partners of the pairs. Furthermore, this study found six factors that accounted for style shifts between the formal and informal. When (1) introducing a new topic and (2) closing a topic, speakers shifted from informal to formal style. This signaled the opening of a new topic directly to the addressee. On the other hand, they shifted from formal style to informal style when (1) expressing feelings, (2) using self-directed utterances, (3) asking questions for confirmation or inference, and (4) adjusting to the context (formality and/or deference). The follow-up interviews revealed that the factors referred to as (1) expression of feelings, (2) self-directed utterances, and (3) questions for confirmation or inference were used by some speakers unconsciously. The self- directed utterances of factor (2) were divided into three types: soliloquy-like remarks, asking oneself a question, and recalling something. Factor (4) adjusting to the context (formality and/or deference), formal style was used to show politeness toward the addressee, and informal style was used to show friendliness, casualness, or empathy. Friendliness, casualness, or empathy was conveyed by use of informal style when the speakers' utterances brought laughter to the context and/or when the speakers showed empathy for the addressee.

Evidentials are one of the language codes that convey the speaker's beliefs in terms of the degree of reliability of information and how the speaker obtained information (Chafe, 1986; Ishida, 2006; McCready and Ogata, 2007). Evidentials play an important role in communication since they also function to show the speaker's attitude toward the interlocutors by making a sentence softer (Trent 1998). In his theory of territory of information, Kamio (1990, 1997, 2002) proposed that pragmatic rules of evidentials are different in Japanese than in English. Ishida (2006) studied these differences and argued that learners of Japanese (JF learners) face difficulties when conveying information with evidentials in Japanese. This study aimed to see how learners of Japanese as a foreign language (hereafter JF learners) use evidentials differently from Japanese native speakers by replicating Ishida's (2006) study. Discourse data, consisting of utterances produced by Japanese L1 speakers (J-speakers) in Japanese and JF learners in Japanese and English, was produced based on twelve situations where participants were instructed to convey hearsay information verbally to the specific third party. Collected productions were compared to see differences in the frequencies of evidentials, in general, and in terms of the source of information, the timing of conveyance, and the addressees. The study showed that JF learners use evidentials less frequently both in Japanese and English than J-speakers. This less frequent use of evidentials by JF learners in both languages indicates a transfer effect from English to Japanese. Additionally, a close look at each evidential use revealed other factors that might impact the speaker's choice of evidentials. This study revealed that JF learners tend to prefer to use evidentials such as soo da and to itta, while they tend to avoid using lexical evidentials such as rashii, mitai da, and yoo da which require more practice. These findings have implications for future research and for a classroom pedagogical approaches to the use of evidentials.

The need for efficient use of water resources has increased the importance of optimum soil water usage in agricultural systems. Soil temperature has been shown to be important in influencing the early development of many plant species. Many agricultural regions have suboptimal soil temperature regimes for plant growth, and some cultural practices have been shown to reduce near-surface soil temperatures. The seasonal influence of soil temperature on soil water extraction and aboveground and belowground plant growth under variable irrigation was investigated at the USU Greenville Farm in Logan, UT. Soil surface mulches and buried heat cables were used to modify soil temperature. A line-source sprinkler system provided a gradient of water application. During 1987 yields were mainly influenced by irrigation. During 1988 greater soil temperature differences resulted in significant plant growth and yield responses. Soil water depletion corresponded to soil temperature treatments during the early part of the growing seasons. Depth of maximum soil water depletion was about 20 cm deeper for warm treatments. Water uptake rates of earlier-maturing plants in warm treatments were reduced later in the season, so that cumulative seasonal soil water depletion was similar for all temperature treatments. Although depth of rooting was somewhat greater under high than low irrigation during 1988, low irrigation treatments depleted soil water to greater depth. There was no interactive response of plant growth and yield or of soil water depletion to soil temperature and irrigation treatments. Modifications were made to a computer simulation model of the soil-plant-atmosphere system in order to more mechanistically simulate plant water uptake and to include influences of soil temperature on seasonal rooting growth and soil water extraction. The model adequately simulated both the pattern and magnitude of soil temperature influences on soil water depletion, and conclusions drawn from model simulations agreed with field observations during 1987 and 1988.
