This study is a content analysis of sexual incidents in prime time television programming aired during the fall of 1990. This research replicates the content analysis of Sapolsky and Tabarlet (1991), while offering several methodological advances: the Fox network is included, in addition to programs on ABC, CBS and NBC; the context of sexual incidents is analyzed; multiple episodes of each program are coded and compared to find out if presentations of sexuality vary over time; and programs broadcast during network ratings "sweeps" are compared to non-sweeps programs to test the assumption that sweeps programs contain more sexuality. / In addition, this study considers two theories that may explain the possible effects of televised sexuality. Cultivation Analysis contends that viewers of television, over time, come to see television as a real and accurate reflection of the world. Sexual socialization, based on Social Learning Theory, argues that children and adolescents will tend to imitate the activities they see on television. Socialization into dating and sexual responsibility behaviors is thus affected by what is available on television. / The study found that the number of sexual incidents on prime time television has fallen significantly since the study of Sapolsky and Tabarlet (1991), and that programs broadcast during the fall, 1990 ratings sweeps period did not have significantly more sexual content than those broadcast before and after the sweeps. In addition, no significant difference was found between the amount of visual portrayals and sexual language on the Fox network and the amount on ABC, CBS and NBC. However, Fox programs did have significantly more innuendo and suggestiveness. Analysis of the programs by scene showed that some visual behaviors such as kissing and verbal references such as verbal innuendo tend to occur many times per scene, while other behaviors such as implied intercourse happen only once per scene. / Source: Dissertation Abstracts International, Volume: 54-04, Section: A, page: 1138. / Major Professor: Barry S.

The effect of television on the behavior of its viewers is an area of interest in communication theory. This study focuses on the effect of television and psychosocial factors on adolescents' expectations to drink. / The incidence of adolescent drinking is rising and there is a possibility proposed relationship, two theories were probed. The theories are: the Theory of Reasoned Action and Cultivation Effects. / An elaborated version of the Theory of Reasoned Action proposes a relationship between an adolescent's expectation to consume alcoholic beverages and the adolescent's behavioral and normative beliefs. / Cultivation effects reasons that there is a relationship between the amount of television watched and the beliefs viewers have about the "real" beliefs about the world. Hence, the more a viewer watches television, the more likely his/her beliefs about the world are influenced by television's symbols and messages. / The findings revealed television is not a statistically significant predictor of cultivated beliefs about drinking. Additionally, television cultivated beliefs about the consumption of alcoholic beverages are not significantly influential in predicting adolescents' expectations to drink. Furthermore, self-efficacy beliefs and noncultivated behavioral beliefs are significant predictors of adolescents' expectations to drink alcoholic beverages. / Source: Dissertation Abstracts International, Volume: 54-12, Section: A, page: 4296. / Major Professor: Gary R.

Electronic bulletin boards have become more popular with the advent of low cost computers, easily available communication channels, and large network systems. With its public posting of messages, relatively large audiences can read and provide immediate feedback. Network organization provides a hierarchical system to give users access to thousands with like interests across the country, or even the world. / A random sample of bulletin board users was selected from the two major national bulletin board services, CompuServe$\sp\circler$ and Prodigy$\sp\circler,$ and interviewed asynchronously, on-line, using electronic mail. / This study characterized this bulletin board audience focusing on the issues of (1) adoption--what characteristics bulletin board users possess, and (2) social impacts--how bulletin board adoption affects the use of other communication media. / Results of the on-line survey supported adoption hypotheses suggesting bulletin board users are higher educated, more wealthy, and work in more prestigious occupations the average American. Rejected was a similar lower age hypothesis. Open-ended responses to the question "why use boards?" were content analyzed, with selections made to categories in five areas showing a typology of use for this medium. Hypotheses suggesting a reduction of consumption of the media television, books, telephone use, and personal letter writing were supported. Rejected were suggestions of lower magazine reading, face-to-face conversations, and other on-line communication. / The findings also showed significant differences in the CompuServe and Prodigy systems along several of the above variables, in addition to quantity of use, message rate, and family usage patterns. / Source: Dissertation Abstracts International, Volume: 53-09, Section: A, page: 3029. / Major Professor: C.

This dissertation interrogates how Florida’s major electric utility companies actively suppressed the nascent solar energy industry in their effort to consolidate solar energy production into their hands during the 2015-2016 election cycle. Along with this, newspaper coverage of this issue was analyzed to determine how the fight was presented to the public and whether prevailing commercial pressures that influence the news production process affected the coverage of this issue. Finally, audience commentary about this issue was explored to determine how Facebook users made sense of this issue and whether the commentary reflected the prominent themes that were also present in the news coverage. Results highlight the economic and political ties between the utility companies and their support network as well as the solar supporters and their affiliated network that squared off in this fight. Additionally, findings reveal that commercial pressures to the news production process resulted in news coverage that portrayed this issue this to the public from a small handful of viewpoints, limiting the range of perspectives from which this issue may legitimately be discussed. Furthermore, results indicate that Facebook users who commented on this issue largely reflected the same perspectives and concerns that were present in the news coverage. Final conclusions and recommendations for changes to the news production process are provided. / A Dissertation submitted to the School of Communication in partial fulfillment of the requirements for the degree of Doctor of Philosophy. / Spring Semester 2018. / April 12, 2018. / Environmental Communication, Newspapers, Political Economy, Social Media, Solar Energy / Includes bibliographical references. / Jennifer M.

Essay 1 examines how competitive strategies influence MC practices and how MC practices influence financial performance. A model is proposed to link both cost leadership and differentiation strategies with the coordinated implementation of MC practices of elicitation, process flexibility, and logistics, and finally, with the financial performance of the firm. The model is tested using data collected from mass customizers in China. Simultaneous equation modeling and hierarchical regression analyses are used to test the hypotheses embedded in the research model. The results reveal that both cost leadership and differentiation strategies have significant impact on MC practices. Moreover, the results indicate that a successful MC implementation requires that mass customizers use elicitation, process flexibility, and logistics in complement. Firms that can successfully implement all three MC practices tend to have better financial performance. / Essay 2 examines the relationships between supply chain integration (SCI) and MC capabilities. Based on data collected from 292 manufacturing firms located in different countries, the results show that both internal and customer integration contribute positively to MC capability. Positive interaction effects on MC capability are also found between internal and customer integration, and between internal and supplier integration. The results suggest that supplier integration play only a complementary role, supporting internal integration in the development of MC capabilities. Overall, the findings demonstrate the pivotal role of internal integration in supply chain integration. Though current research tends to view SCI as "outward-facing" integration, our results suggest that manufacturing finns should pursue internal integration as the foundation for successful MC. / Essay 3 investigates the roles of service and customer value co-creation in developing MC offerings. Using exploratory case study and grounded theory building, we analyze six Chinese manufacturers in the Pearl River Delta. According to the arguments of service-dominant logic (SDL), the two types of MC offerings (product-centric MC and solution-centric MC) are service provided by manufacturer (fundamental service and resource integration service), and customer value co-creation (information and knowledge exchange and integrated design and manufacturing). Using the configurational approach, we investigate the theoretical typologies among MC offerings, service, and value co-creation. The results suggest that an internal fit exists among the three elements, and the configuration needs to fit with the supply chain capability and task characteristics. / Mass customization (MC) has been considered an important competitive weapon of manufacturers all over the world. Many successful companies adopt it to deal with growing competition characterized by heterogeneous customer demands, accelerated new product development, and shortened product life cycles. Currently, MC has become an imperative in business competition and an important topic for researchers in many disciplines. This dissertation covers three issues about MC: 1) the impact of competitive strategies on MC practices; 2) the effects of SCI on MC capability; and 3) the roles of service and customer value co-creation in developing MC offerings. / [essay 1].

基質輔助鐳射解吸電離飛行時間質譜儀是一種重要的儀器被用來對生物樣品做結構分析，通過諸如源後裂解和碰撞誘導裂解兩種方式實現。然而同碰撞誘導裂解比較，源後裂解具有較低的裂解效率。 / 本課題的目的就是提升我們原有的基質輔助鐳射解吸電離飛行時間質譜儀在結構分析方面的能力。對儀器的改造包括(a)將原有的兩級反射器替換為曲線場反射器(b)安裝一個高壓浮地的碰撞室(c)安裝一個同軸的粒子探測器。曲線場反射器和同軸粒子探測器可以實現母離子跟碎片離子的同時監測，碰撞室可以實現母離子的碰撞裂解。在儀器的性能評估實驗中，母離子和所有的源後裂解的碎片離子同時被探測器記錄。在碰撞誘導裂解實驗中，母離子與碰撞氣體分子發生高能碰撞後大多生成了小質量數的碎片離子，實驗中還發現將碰撞室浮地後，碎片離子的質量解析度和信號強度都有了顯著改進。 / 通過比較曲線場反射器和兩級反射器的性能，我們提出了一種雜化反射器設計，這種反射器在第二片和最後一片電極片上都有可調電壓。第二片和最後一片電極片之間的電場遵循曲線場分佈。這種反射器有兩種操作模式：MS 和MS/MS 模式。類比實驗和分析計算的結果顯示在MS 模式裡，通過調整兩個可調電壓u1 和u2，不同質量離子在反射器裡的反轉點可以被設置在一個最優的位置從而得到最優的質量解析度。在MS/MS 模式裡，一個全質量範圍的譜圖和若干個較窄質量範圍的譜圖可以通過改變兩個可調電壓獲得，其中較窄質量範圍的譜圖具有更高的質量解析度用來分析某個質量範圍內的碎片離子的細節資訊。這些結果表明這種雜化反射器兼具曲線場反射器和兩級反射器的優點。 / Matrix-assisted laser desorption/ionization time-of-flight mass spectrometer (MALDI-TOFMS) is an important instrument for structural analysis of biological samples through such as post-source-decay (PSD) or collision-induced dissociation (CID) analysis. However, PSD analysis is a relatively low-efficiency method compared with CID analysis. / This project aims to upgrade the TOF instrument to a high performance TOF/TOF instrument. The modification involves (a) the replacement of the two-stage reflectron with a home-built curved-field reflectron (CFR); (b) the fabrication of a high voltage floated collision cell; and (c) the installation of a coaxial microchannel plate (MCP) detector. The CFR and coaxial detector allow simultaneous reflection of precursor ions and all fragment ions. The collision cell provides an effective means of ion activation (CID). In the performance test, precursor ions with almost all the fragment ions were recorded simultaneously in PSD analysis. In CID experiments, the precursor ions were found to undergo fragmentation due to high energy collision with the target gas and by floating the collision cell to high potential (several kV), the mass resolution and signal intensities of low mass fragment ions were improved substantially. / By comparing the performance of curved-field and two-stage reflectron, a hybrid reflectron was proposed, which has adjustable high voltages U1 and U2 on the second and last electrode element, respectively. The electrostatic potential between the second and last electrode element follows curved-field distribution. There are two operation modes for this reflectron: MS and MS/MS mode. Results from theoretical investigation and experiments showed that in MS mode, optimal energy compensation could be achieved through tuning the values of U1 and U2; in MS/MS mode, a full mass scale spectrum as well as spectra segments with high mass resolution within a narrower mass range could be obtained by setting U1 and U2 with appropriate values. These results indicated that the hybrid reflectron had the advantages both of curved-field reflectron and two-stage reflectron. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Detailed summary in vernacular field only. / Li, Gang. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2012. / Includes bibliographical references (leaves 131-137). / Electronic reproduction.
