1	Characterization of Uplink Transmit Power and Talk Time in WCDMA Networks Bhupathi Raju, Arjun 12 September 2008 (has links) As 3G handset manufacturers add more and more features such as multimedia applications, color displays, video cameras, web browsing, gaming, WLAN, and MP3 players, the current consumption of a handset is ever increasing. Of the many components, the RF power amplifiers receive the most attention as they draw significant battery current and continue to represent the largest power load on the battery. In order to improve the overall efficiency of a power amplifier, it is important to know the operating uplink transmit power levels of a mobile phone in the WCDMA network. The work in this thesis makes two major contributions. First is the characterization of uplink transmit power in WCDMA networks based on current network data (collected in AT&T's WCDMA network) and realistic usage scenarios. Second is an investigation of the relationship between the battery life and the probability distribution function of the transmit power. Another important finding is that the talk time estimates using field tests, lab testing and theoretical expressions all give results to within 5%. Based on these data, design goals for WCDMA power amplifiers (in order to improve the talk times significantly) are suggested. The output power levels where the PA efficiencies have to be improved in order to significantly increase the battery life of WCDMA handsets are presented. / Master of Science Talk time Power Amplifiers WCDMA Transmit Power
2	An analysis of teacher question types in inquiry-based classroom and traditional classroom settings Kim, Sungho 01 January 2015 (has links) This study examined the differences and patterns for three categories between an argument-based inquiry group and a traditional group over the period of the SWH (Science Writing Heuristic) project: (1) teacher talk time, (2) structure of questions (question types), and (3) student responses. The participating teachers were chosen randomly by a convenient sampling method because the data were collected previously from the SWH project. Each group had thirty teachers. A total of sixty teachers participated in the study. Student responses were part of the study to evaluate the effect of open-ended question types but students were not direct participants in the study. Each teacher was asked to send a recorded video clip of their class at the end of each semester (spring and fall) over two years. Each teacher sent four video clips for the project. A total of two hundred forty video clips was analyzed to gather the information regarding the three categories. The first category was teacher talk time. It was measured in seconds only when teachers interacted with students with the topic. The second category was the structure of questions (question types). It consisted of two question types (open-ended and close-ended). Under the open-ended question category, there were three sub-question types: (1) asking for explanation (AE), (2) asking for self-evaluation of reasoning (AF), and (3) asking for self-evaluation of others' reasoning (AFO). Under the close-ended question category, there were two sub-question types: (1) asking for factual information (AI) and (2) asking for confirmation (AC). Each sub- question type was counted numerically. The last category was student responses. Student responses consisted of higher-order thinking and lower-order thinking. Under the higher-order thinking category, there were three sub-types: (1) explanation responses (E), (2) self-evaluation of reasoning responses (SE), and (3) self-evaluation of others' reasoning responses (SEO). Under the lower-order thinking category, there was one sub-type: simple responses (S). Each sub type was counted numerically. Based on the descriptive results (the length of teacher talk time in seconds, the number of question types, and the number of student responses), repeated measures ANOVA was conducted to find any differences and patterns for teacher talk time, structure of questions and student responses between the treatment and control groups over the period of the project and across time (four different time points). The results showed that there were clear differences for teacher talk time, the structure of questions, and student responses between the treatment and control groups over the period of the project and across time. The treatment group teachers talked less and used more open-ended questions than the control group teachers. The treatment group students displayed more higher-order thinking responses than the control group students. publicabstract Inquiry Learning Student responses Teacher questioning Teacher talk time Teaching
3	From Snow White to Frozen : An evaluation of popular gender representation indicators applied to Disney’s princess films / Från Snövit till Frost : En utvärdering av populära könsrepresentations-indikatorer tillämpade på Disneys prinsessfilmer Nyh, Johan January 2015 (has links) Simple content analysis methods, such as the Bechdel test and measuring percentage of female talk time or characters, have seen a surge of attention from mainstream media and in social media the last couple of years. Underlying assumptions are generally shared with the gender role socialization model and consequently, an importance is stated, due to a high degree to which impressions from media shape in particular young children’s identification processes. For young girls, the Disney Princesses franchise (with Frozen included) stands out as the number one player commercially as well as in customer awareness. The vertical lineup of Disney princesses spans from the passive and domestic working Snow White in 1937 to independent and super-power wielding princess Elsa in 2013, which makes the line of films an optimal test subject in evaluating above-mentioned simple content analysis methods. As a control, a meta-study has been conducted on previous academic studies on the same range of films. The sampled research, within fields spanning from qualitative content analysis and semiotics to coded content analysis, all come to the same conclusions regarding the general changes over time in representations of female characters. The objective of this thesis is to answer whether or not there is a correlation between these changes and those indicated by the simple content analysis methods, i.e. whether or not the simple popular methods are in general coherence with the more intricate academic methods. / <p>Betyg VG (skala IG-VG)</p> Disney princesses Disney princesses gender Bechdel Bechdel test Walt Disney Pixar Frozen children girl culture gender representations talk time talktime gendertimer equality content analysis female feminism feminist gender role socialization model gender role socialization model passive domestic active media post-feminist gender role portrayals key measures popular nature or nurture genes or environment gender differences expressions of gender gender experiments neurological brain plasticity constructivist cultivation theory social cognitive theory quantitative quantitative measures quantitative methods stereotypes stereotype stereotypical women character count biological sex biological gender metrics femininity textual analysis submissive submissive behaviour independence daddy's girl patriarchy patriarchal patriarchal approval wicked women old wicked women wicked witch male masculine masculine characteristics feminine characteristics genders marrying marriage love at first sight empowerment fairy tale fairy tales film movie films movies Mulan Pocahontas Snow White Snow White and the seven dwarfs Cinderella Sleeping Beauty Little Mermaid The Little Mermaid Beauty and the Beast Aladdin Tangled Brave Frozen The Princess and the Frog Merida relationship relationship formation true love true love's kiss sisterhood sisterly Grimm Grimm brothers parental approval matriarchal approval matriarchal matriarchy stereotyping evil queen rate rater rating measure measuring wicked stepmother binary gender gender binarity binary genders gender identities gender identity gender identity formation identity formation animation cell animation the Smurfette principle strong women strong girls girlie positivism positivistic film studies analysis analyses antagonism action coding cultivation effect cultivation effects socialization effect socialization effects coded content analysis simple metrics cognition theory connotations cultivation theory socialization theory depictions of femininity plasticity human brain damsels in distress feminist research inequality gender inequality media studies heroines mass media social media images of women woman as image reading interpretation modern day fairy tales Disney prinsessor Disneyprinsessor Disney-prinsessor kön genus genusvetenskap Bechdel Bechdel test Bechdeltest Bechdeltestet Walt Disney Pixar Frost barn flickor kulturuppväxt representationer skildringar intryck taltid talk time talktime gendertimer jämlikhet innehållsanalys feminin feminism könsroll könsroller socialisering socialiseringsmodellen passiv hushållsarbete aktiv media post-feministisk postfemininstisk nyckeltal populärvetenskaplig populärvetenskapligt naturen uppväxt eller gener gener eller upppväxt uppfostran genetik könsskillnader könsuttryck experiment hjärnan plasticitet konstruktivism kultivationsteori kognitiv teori kvantitativ kvantitativa mått kvantitativa metoder stereotyper stereotyp stereotypisk kvinnnor kvinna kön biologiskt kön mått nyckeltal femininitet textanalys filmanalys kuvad underkastad submissiv oberoende pappas flicka patriarkat patriarkisk patriarkalt godkännande manlig maskulin kön genus äktenskap kärlek vid första ögonkastet saga sagor bröderna Grimm film Mulan Pocahontas Snövit och de sju dvärgarna Askungen Törnrosa Den lilla Sjöjungfrun Skönheten och Odjuret Aladdin Trassel Modig Frost Prinsessan och Grodan Merida förhållanden sann kärlek Grimm matriark matriarkisk patriarkalt godkännande matriarkalt godkännande bedöma betygsätta mått mäta ond styvmor binära kön könsidentitet könsidentiteter animation Smurfan starka kvinnor starka flickor positivistisk positivism filmvetenskap filmstudier antagonism protagonist hjältinna kodning kultivationseffekten socialiseringseffekten socialisationseffekten kodad innehållsanalys förenklade mått kognitiv teori konnotationer konnotera feministisk forskning könsbalans mediastudier mediestudier massmedia social media bilder av kvinnor kvinnan som bild images of women woman as image reading interpretation modern day fairy tales tolkning
