We have also tried to evidence how such learners assess the level of their English discursive knowledge by means of discursive practices involving humor, as well as the implications of such appropriation to their future careers as teachers of English as L2/FL. Data were collected in an English intermediate group of undergraduates of Letras/Inglês of the Universidade Federal de Goiás. Efforts were made to design and integrate activities focusing on the humor of the American situation comedy Friends (BRIGHT; KAUFFMAN; CRANE, 1994-2004) into eight classes of the original course program taking place between November 2015 and February 2106. Four Friends episodes were explored. The data collection was carried out by means of a questionnaire, video and audio recordings of the classes, field notes of the teacher-researcher observations and audios of interviews made with each participant after the classroom work was over. This paper is based on the dialogic perspective of Bakhtin (2011, 2012, 2014), on humor studies with emphasis on L2/FL teaching and learning (BELL; POMERANTZ, 2014; 2015; 2016) as well as on the nexus between humor, language and culture (KRAMSCH, 1998, 2013; RISAGER, 2006; CORBETT, 2003, POPA, 2014; DAVIES, 2014; DICIOCCIO; MICZO, 2014; ATTARDO, 1994, 2014). The data analysis reveals that the participants’ different levels of comprehension and appreciation of humor in Friends depend both on their linguistic proficiency and on their background knowledge on American culture and of world globalized culture. Such factors led to the active and responsive engagement of the undergraduates in dialogical interactions and the collective construction of meanings during the classes. As the participants positioned themselves at different levels of appropriation of the humor in the LC2, they also recognized the importance of such factor in the construction of their subjectivities as future English teachers. / Este estudo de caso etnográfico teve como objetivo demonstrar até que ponto doze aprendizes de inglês como L2/LE se apropriam dos elementos constitutivos do humor no nível discursivo da languaculture-inglês. Buscamos ainda evidenciar como esses aprendizes avaliam o seu nível de conhecimento discursivo do inglês por meio de práticas discursivas envolvendo o humor, assim como as implicações dessa apropriação do humor em inglês para suas futuras práticas profissionais como professores dessa L2/LE. Os dados foram gerados em uma turma de Inglês 4 da Licenciatura em Letras/Inglês da Faculdade de Letras da Universidade Federal de Goiás (FL/UFG). Foi implementado um esforço para desenhar e integrar atividades explorando o humor da comédia de situação estadunidense Friends (BRIGHT; KAUFFMAN; CRANE, 1994-2004) em oito aulas do programa da disciplina entre novembro de 2015 e fevereiro de 2016. Foram explorados quatro episódios de Friends. A geração de dados se deu a partir do questionário aplicado no início do estudo, das gravações em áudio e vídeo das aulas, dos registros das observações da professora-pesquisadora em diário de campo e das entrevistas com os participantes após finalizados os trabalhos em sala de aula. Este trabalho fundamenta-se na perspectiva dialógica de Bakhtin (2011, 2012, 2014), nos estudos sobre humor com ênfase no ensino aprendizagem de línguas (BELL; POMERANTZ, 2014; 2015; 2016) assim como nas inter-relações entre humor, língua, cultura (KRAMSCH, 1998, 2013; RISAGER, 2006; CORBETT, 2003, POPA, 2014; DAVIES, 2014; DICIOCCIO; MICZO, 2014; ATTARDO, 1994, 2014). Os dados revelam que os diferentes níveis de compreensão e apreciação do humor na languaculture-inglês (LC2) ora dependem da proficiência linguística dos participantes, ora de seu conhecimento prévio de fatores da cultura estadunidense e da cultura globalizada. Isso provoca o engajamento responsivo ativo dos licenciandos em interações dialógicas significativas e a construção conjunta de sentidos durante as aulas. Ao se posicionarem de formas distintas quanto ao seu nível de apropriação do humor na LC2, os alunos evidenciam a importância desse fator na construção de suas subjetividades como futuros professores de inglês.

Illegal substance use in the United States is a growing problem, and a western state has a higher than average rate of drug offenders. Many courts, including misdemeanor courts, have limited to no budget for drug treatment programs outside of the drug court treatment programs. As such, many court-ordered drug treatment programs, when drug counseling is ordered in exchange for a reduction in charges, are outsourced to privately owned companies. The drug counseling entails a single 8-hour outsourced drug counseling course, which includes either in-person, online, or correspondence-based counseling. The purpose of this study was to investigate the effectiveness of the three modalities of the lower level drug counseling course. Effectiveness was measured by comparing recidivism rates of offenders completing each of the three modalities of the program. A second goal of the study was to investigate whether relationships exist in recidivism rates as a function of modality of program delivery, type of drug used by offenders, risk of re-offense, or an interaction between the three. Archival data (N = 395) were collected from a misdemeanor court, and the results of an ordinal logistic regression indicated a statistically significant relationship between recidivism, risk, and modalities of counseling. The modality that was most effective was the online modality of counseling, for offenders who had no risk, and reduced the potential for recidivism by 79%. The results of this study could assist the local government in determining the effectiveness of each of the three modalities of the abbreviated drug counseling program and assist in future decisions regarding development of drug counseling programs and necessary funding for those programs, providing potential for positive social change.

Emerging research highlights the role of self-regulation in the treatment of sexual offenders. Safe Offender Strategies (SOS) is a manualized sex offender treatment program that emphasizes the role of self-regulation and self-regulatory skills development in sex offender treatment, particularly for offenders with serious mental illness and intellectual/developmental disabilities. The current study involves 156 adult male sexual offenders in an inpatient psychiatric setting who received SOS treatment for a period ranging from 6 months to 1 year. Participants’ baseline and treatment data were obtained from archival medical records describing 1 year pre-treatment and up to 2 years of treatment participation. Dependent variables included monthly count rates of verbal and physical aggression and contact and noncontact sexual offending, as well as sexual deviancy attitudes, self-regulatory ability, and cooperation with treatment and supervision, as measured by the Sex Offender Treatment Intervention and Progress Scale (SOTIPS). Data were examined via paired-samples t tests, regression, and multilevel modeling, examining the impact of overall percentage of SOS groups attended over time, comparing participants’ baseline measures to data from 2 years of treatment. The impact of predicted risk was also evaluated. Significant treatment dose effects were identified for improvements in aggression, sexual offending, and indicators of treatment compliance and change. These findings suggest that the skills-based, self-regulation approach utilized in SOS may be effective in improving clients’ aggressive and sexual behaviors, attitudes toward their offenses and treatment, and self-regulatory ability over time. Implications for further research and treatment generalizability are discussed.

Quantum dot infrared photodetectors (QDIPs) have emerged as a promising technology in the mid- and far-infrared (3-25 μm) for medical and environmental sensing that have a lot of advantages over current technologies based on Mercury Cadmium Telluride (MCT) and quantum well (QW) infrared photodetectors (QWIPs). In addition to the uniform and stable surface growth of III/V semiconductors suitable for large area focal plane applications and thermal imaging, the three dimension confinement in QDs allow sensitivity to normal incidence, high responsivity, low darkcurrent and high operating temperature. The growth, processing and characterizations of these detectors are costly and take a lot of time. So, developing theoretical models based on the physical operating principals will be so useful in characterizing and optimizing the device performance. Theoretical models based on non-equilibrium Green's functions have been developed to electrically and optically characterize different structures of QDIPs. The advantage of the model over the previous developed classical and semiclassical models is that it fairly describes quantum transport phenomenon playing a significant role in the performance of such nano-devices and considers the microscopic device structure including the shape and size of QDs, heterostructure device structure and doping density. The model calculates the density of states from which all possible energy transitions can be obtained and hence obtains the operating wavelengths for intersubband transitions. The responsivity due to intersubband transitions is calculated and the effect of having different sizes and different height-to-diameter ratio QDs can be obtained for optimization. The dark and photocurrent are calculated from the quantum transport equation provided by the model and their characteristics at different design parameter are studied. All the model results show good agreement with the available experimental results. The detectivity has been calculated from the dark and photocurrent characteristics at different design parameters. The results shows a trade off between the responsivity and detectivity and what determines the best performance is how much the rate of increase of the photocurrent and dark current is affected by changing the design parameters. Theoretical modeling developed in the thesis give good description to the QDIP different characteristics that will help in getting good estimation to their physical performance and hence allow for successful device design with optimized performance and creating new devices, thus saving both time and money. / Thesis / Doctor of Philosophy (PhD)

Syftet med studien är att skapa förståelse för hur kvinnor på kvinnodominerade arbetsplatser upplever kritik. Studien kommer att vara en fältstudie vari man granskar kvinnor som är verksamma inom förskolan, då tidigare forskning visat på en klar majoritet av kvinnor inom denna yrkeskår. Avsikten med studien är inte att uppnå någon objektiv sanning av verkligheten, dock avser denna studie tolka eventuella fenomen som rör ämnet, samt skapa en förståelse för individens syn på begreppet. Informanterna har valts ut strategiskt, vidare präglas informanternas deltagande av självselektion. Man kommer inte att ta hänsyn till andra variabler än kön vad gäller urvalet. Teorier som studien vilar på är den symboliska interaktionismen där bland annat dess syn på rationalitet behandlas. Vidare tas Johan Asplunds teori om social responsivitet i beaktning och avslutningsvis Erving Goffmans teori om identitetsskapande. De slutsatser som kan dras i och med denna studie är att relationerna mellan individerna i en grupp verkar ha stor betydelse för hur man upplever kritik. För att undvika missförstånd kring det valda ämnet verkar allmän mening råda att "definitionen av situationen" är något man bör ta i beaktande, detta då kritik till en början upplevs som någonting negativt. / The purpose of this study is to create an understanding of how women in female dominated workplaces are experiencing criticism. The study will be a field study which is examining women who are active in preschool, when previous research has demonstrated a clear majority of women in this profession. The intention of this study is not to create any objective truth of reality, however, relate this study to interpret and describe any phenomena related to the topic, and create an understanding of the individual's perception of the concept. The informants were chosen strategically, further characterized the informants' participation of self-selection. It will not take into account, variables other than gender in terms of selection. Theories that the study rests on is the symbolic interactionism, which, among other things, its view of rationality is treated. Furthermore the theory of Johan Asplund, social responsivity, is taken into consideration and, finally, Erving Goffman's theory of identity formation. The conclusions to be drawn, in and of this study is that the relations between individuals in a group seems to have a major impact on how people perceive criticism. To avoid misunderstandings about the chosen topic appears public opinion, advise that the "definition of the situation" is something you should take into consideration, so where the spontaneous reaction of criticism is negative.

This thesis describes an investigation into the suitability of complementary metal oxide semiconductor (CMOS) active pixel sensor (APS) devices for scientific imaging applications. CMOS APS offer a number of advantages over the established charge-coupled device (CCD) technology, primarily in the areas of low power consumption, high-speed parallel readout and random (X-Y) addressing, increased system integration and improved radiation hardness. The investigation used a range of newly designed Test Structures in conjunction with a range of custom developed test equipment to characterise device performance. Initial experimental work highlighted the significant non-linearity in the charge conversion gain (responsivity) and found the read noise to be limited by the kTC component due to resetting of the pixel capacitance. The major experimental study investigated the contribution to dark signal due to hot-carrier injection effects from the in-pixel transistors during read-out and highlighted the importance of the contribution at low signal levels. The quantum efficiency (QE) and cross-talk were also investigated and found to be limited by the pixel fill factor and shallow depletion depth of the photodiode. The work has highlighted the need to design devices to explore the effects of individual components rather than stand-alone imaging devices and indicated further developments are required for APS technology to compete with the CCD for high-end scientific imaging applications. The main areas requiring development are in achieving backside illuminated, deep depletion devices with low dark signal and low noise sampling techniques.

Realization of spectral responsivity scale was studied in three stages. Firstly, absolute optical power measurements using Electrical Substitution Cryogenic Radiometer (ESCR) was studied. The absolute measurements were done at discrete laser wavelengths of tunable Ar+ (488 nm and 514.5 nm), Nd:YAG (532 nm) and fixed He-Ne (632.8 nm) laser sources. To increase measurement accuracy the method used for the stabilization of laser beams, transmittance measurements of optical windows, and minimization of scattered beams were discussed. Secondly, realization of absolute responsivity scale between 350- 850 nm ranges was studied. The scale based on reflection type trap detectors consisting of three silicon photodiodes. Various measurement systems were established in order to make optical characterization of trap detectors like non-linearity, surface non-homogeneity, polarization dependency, reflectance, and internal quantum efficiency. The absolute responsivity was linked to the absolute optical power by measuring the current response of trap detectors to the absolute power measured by ESCR system at laser wavelengths. Using models for the trap detector&rsquo / s, reflectance and internal quantum efficiency the scale between 350- 850 nm ranges was realized with an uncertainty of 0.05 %. Finally, the spectral responsivity scale in ultraviolet (UV) and near-infrared (NIR) regions was realized using Electrically Calibrated Pyroelectric Radiometer (ECPR). Optically characterizing the spatial non-uniformity of pyroelectric detector and its surface reflectance, the spectral responsivity scale was established with uncertainties &plusmn / 0.5-1.0 % between 250 nm and 350 nm and &plusmn / 0.5-1.5 % between 850 and 2500 nm.

In this doctoral thesis we describe a series of stimuli-responsive polymers which could be used as diagnostic tools or as smart drug delivery systems with simultaneous diagnosis (theranostics). All hereby mentioned polymers are thermoresponsive copolymers of (N-2,2-difluoroethyl)acrylamide exhibiting lower critical solution temperature in aqueous milieu. This means that they are water-soluble at low temperature while when heated above a certain temperature, they self-assemble into nano- or macro- sized assemblies. Because of the high concentration of fluorine atoms, all these polymers could be used as 19 F MRI tracers. We designed multiple different thermoresponsive, thermo- and pH-responsive, thermo-and reactive-oxygen-species-responsive polymers that could find numerous discussed applications in human medicine. We investigated their physico-chemical properties with 1 H and 19 F nuclear magnetic resonance (NMR), size exclusion chromatography (SEC), elemental analysis, dynamic light scattering (DLS), static light scattering (SLS), small angle neutron scattering (SANS), small-angle X-ray scattering (SAXS), and turbidimetry. After the physicochemical optimization of the parameters for the selected applications, their biocompatibility was tested in vitro. Several promising polymers were tested in vivo...
