The Mirror Room Project: A Critical Ethnographic Program Evaluation of a Teaching Personal and Social Responsibility Based Youth Development Program

Amongst a host of other benefits, proper physical education has the possibility to create a safe place where responsibility can be transferred from the teacher/facilitator, to the student. This is especially true with an underserved population. This critical program evaluation of the program CHARM was done for the purpose of program improvement. This research was a place for participants to share their experiences of the program. The participants were 5 underserved youth, 5 undergraduate students, 3 teachers and 1 graduate student. Observations, interviews, and document analysis were used to gather data. Data was analyzed using a first level read-through, and two second-level analyses. Summaries were written, and cross-case analyses were completed. The main finding of the research was the development of a Handbook, which is a guide to running the program. Secondary findings include issues of program structure, goal setting, meaningful relationships, roles, SNAP, and an outlier in the data.

Social rejection of minority groups and its impacts on the individual's identity and perception of the self : exploring homosexual and racial identities in James Baldwin's Giovanni's room and Just above my head

Ce mémoire examine la question de la formation de l'identité en tant que procédure compliquée dans laquelle plusieurs éléments interviennent. L'identité d'une personne se compose à la fois d’une identité propre et d’une autre collective. Dans le cas où l’identité propre est jugée sévèrement par les autres comme étant déviante, cela poussera la personne à, ou bien maintenir une image compatible avec les prototypes sociaux ou bien résister et affirmer son identité personnelle. Mon travail montre que l'exclusion et la répression de certains aspects de l'identité peuvent causer un disfonctionnement psychique difficile à surmonter. Par contre, l'acceptation de soi et l’adoption de tous les éléments qui la constituent conduisent, certes après une longue lutte, au salut de l’âme et du corps. Le premier chapitre propose une approche psychosociale qui vise à expliquer le fonctionnement des groupes et comment l'interaction avec autrui joue un rôle décisif dans la formation de l'identité. Des éléments extérieurs comme par exemple les idéaux sociaux influencent les comportements et les choix des gens. Toutefois, cette influence peut devenir une menace aux spécificités personnelles et aux traits spécifiques. Le deuxième chapitre examine la question des problèmes qu’on risque d’avoir au cas où les traits identitaires franchiraient les normes sociales. Nous partons du problème épineux de la quête de soi dans Giovanni's Room de James Baldwin. L'homosexualité de David était tellement refusée par la société qu’elle a engendrée chez lui des sentiments de honte et de culpabilité. Il devait choisir entre le sacrifice des aspects de soi pour satisfaire les paradigmes sociaux ou bien perdre ce qu’il a de propre. David n'arrive pas à se libérer. Il reste prisonnier des perceptions rigides au sujet de la masculinité et de la sexualité. Mon analyse se focalise essentiellement sur l'examen des différents éléments théoriques qui touchent la question du sexe et de la sexualité. Le résultat est le suivant : plus les opinions dominantes sont rigides et fermes, plus elles deviennent une prison pour l’individu. Par contre, plus elles sont tolérantes et flexibles, plus elles acceptent les diversités de l'identité humaine. Dans le dernier chapitre, j'examine la question de la représentation des relations entre les caractères masculins dans Just Above My Head. L'homosexualité est présentée comme un moyen sacré pour exprimer l'amour. Les caractères révèlent leurs sentiments implicitement à travers les chants spirituel tel que le gospel ou bien explicitement à travers la connexion physique. Dans ce roman, Baldwin montre que c'est seulement grâce à la sincérité et à l'amour que l'individu peut atteindre la libération du soi.

L'histoire de l'art mise en pièces : analyse matérielle, spatiale et temporelle de la period room comme dispositif muséal

Dans cette thèse, nous étudions la period room présentée dans le musée d’art. À travers un examen de sa spécificité matérielle, spatiale et temporelle, nous analysons les mécanismes propres à cette stratégie de mise en exposition et nous identifions ses principales conditions de possibilité. Ce faisant, nous étudions les différents savoirs qui sont sollicités par la period room, leurs interactions ainsi que l’apport réciproque de cette stratégie de mise en exposition à la construction de ces savoirs et ce, de manière à établir les fondements d’une épistémologie de la period room. Nous montrons ainsi quelle est sa contribution particulière à l’élaboration et à la médiation de l’histoire dans l’espace muséal. Grâce à cette étude, nous posons des assises conceptuelles qui permettent de repenser le rôle de la period room pour la discipline de l’histoire de l’art, déjouant par le fait même les apories de l’historicisme et de l’authenticité en vertu desquelles la period room est le plus souvent discréditée. Nous procédons par études de cas à partir d’un corpus principalement composé de period rooms ayant pour référents des intérieurs français de la seconde moitié du 18ième siècle et qui sont présentées dans des musées d’art américains (Frick Collection, Metropolitan Museum of Art, Philadelphia Museum of Art) et dans un musée canadien d’histoire naturelle et culturelle (Royal Ontario Museum). Dans la première partie de la thèse, nous établissons la typologie muséographique de la period room et nous envisageons les enjeux, notamment idéologiques, associés à la question de son « authenticité » à travers une analyse de son double statut de pastiche et de simulacre. Nous posons en outre l’un des fondements théoriques de notre étude en montrant que, parce qu’elle est formée de l’articulation entre pouvoirs et savoirs, la period room est un dispositif au sens où l’entendent Michel Foucault (1977) et Giorgio Agamben (2007). Dans la seconde partie, nous examinons la spécificité matérielle de la period room en démontrant comment elle est simultanément une réunion d’objets et un « tout », c’est-à-dire un objet muséographique en elle-même. Nous étudions les implications épistémologiques de cette idée pour la représentation de l’histoire proposée au moyen de la period room, tout en portant une attention particulière aux enjeux politiques qui informent cette représentation dans l’espace muséal. Dans la troisième partie, nous nous concentrons sur les particularités spatiales et temporelles de cette stratégie de mise en exposition et nous démontrons que, en dépit de son apparente unité de lieu et de temps, la period room est composée de plusieurs espaces et concentre plusieurs temps. En puisant dans la spécificité même de ce dispositif, nous élaborons des outils théoriques et méthodologiques inédits qui contribuent à repenser la fonction de la period room pour la mise en forme et la transmission de l’histoire. En conclusion, nous présentons une dernière étude de cas qui, examinant l’intervention de Valerie Hegarty dans trois period rooms du Brooklyn Museum (2013), synthétise les principaux enjeux traités dans la thèse et défend la valeur d’actualité de la period room.

Zeolite Encapsulated Complexes Of Fe,Co,Ni,Cu And Pd:Synthesis , Characterization And Catalysis-2003

This thesis deals with the synthesis, characterization and catalysis activity studies of some zeolite encapsulated complexes. Encapsulation inside the zeolite cages makes the catalysts more stable. Further, the framework prevents the complexes from dimerising. Catalysis by metal complexes encapsulated in the cavities of zeolites and other molecular sieves has many features of homogeneous, heterogenous and enzymatic catalysis. Serious attempts has been made to gain product selectivity in catalysis .The catalytic activity shown by the encapsulated complexes can be correlated to the structure of the active site inside the zeolite pore. It deals with the studies on the partial oxidation of benzyl alcohol to benzaldehyde. The oxidatio was carried out using hydrogen peroxide as oxidant in presence of PdYDMG and CuYSPP as catalysts. The product (benzaldehyde) was detected using TLC and confirmed using GC.The catalytic activity of the complexes was tested for oxidation under various conditions. The operating conditions like the amount of the catalyst, reaction time, oxidant to substrate ratio, reaction temprature, and solvents have been optimized. No further oxidation products were obtained on continuing the reaction for four hours beyond the optimum time. Maximum conversion was obtained at room temperature and the percentage conversion decreased with increase in temperature. Activity was found to be dependent on the solvent used. With increasing awareness about the dangers of environmental degradation, research in chemistry is getting increasing geared to the development of “green chemistry,” by designing environmentally friendly products and processes that bring down the generation and use of hazardous substances.

Analysis of Some Queueing Models Related To N-Policy: Operations Research

This study is about the analysis of some queueing models related to N-policy.The optimal value the queue size has to attain in order to turn on a single server, assuming that the policy is to turn on a single server when the queue size reaches a certain number, N, and turn him off when the system is empty.The operating policy is the usual N-policy, but with random N and in model 2, a system similar to the one described here.This study analyses “ Tandem queue with two servers”.Here assume that the first server is a specialized one.In a queueing system,under N-policy ,the server will be on vacation until N units accumulate for the first time after becoming idle.A modified version of the N-policy for an M│M│1 queueing system is considered here.The novel feature of this model is that a busy service unit prevents the access of new customers to servers further down the line.It is deals with a queueing model consisting of two servers connected in series with a finite intermediate waiting room of capacity k.Here assume that server I is a specialized server.For this model ,the steady state probability vector and the stability condition are obtained using matrix – geometric method.

Phase transitions in lithium ammonium sulfate below room temperature: An ultrasonic study

A detailed ultrasonic study of the elastic properties of lithium ammonium sulfate ~LiNH4SO4! or LAS has been carried out below room temperature. The elastic constants of LAS at room temperature are reported. The discrepancy present in earlier elastic constant data associated with the different choice of axes for this orthorhombic system are clarified. The results of the temperature variation study down to 220 K confirm the ferroelastic phase transition at 285 K and establish a thermal hysteresis of about 2.5 K between the cooling and heating cycles. Results of the investigation on the suspected weak phase transition at 256 K suggest that this transition occurs at 242 K on cooling and at 256 K on heating, thus having a thermal hysteresis of about 14 K. However, since the observed elastic anomaly for this transition is very small, the nature of this transition still remains unclear

Studies on the technological aspects and economic efficiency of trawl gear operating along the Cochin coast

Trawling, despite being heavily energy expensive, still continues to be the most energy expensive fishing method particularly so in View of the export oriented nature of the Indian seafood industry. This study therefore aims at analyzing the efficiency of trawls operation from Cochin, an important fishing center along the southwest coast of India. The analysis is made along two perspectives - economic and technological. Even though technological efficiency complement economic efficiency, in the fishing parlance, parameters like the size composition of the catch, selectivity factors, etc., will have a direct bearing on the technological qualities of the trawl, and which parameters will have a significant impact on the effective exploitation of a fishery stock. Whereas the technological analysis aims at improving the efficiency with regard to the effective utilization of fuel and fishery stocks, economic analysis ascertains the present status of the trawling operations from the commercial angle.

Near fifty percent sodium substituted lanthanum manganites—A potential magnetic refrigerant for room temperature applications

Nearly half of lanthanum sites in lanthanum manganites were substituted with monovalent ion-sodium and the compound possessed distorted orthorhombic structure. Ferromagnetic ordering at 300K and the magnetic isotherms at different temperature ranges were analyzed for estimating magnetic entropy variation. Magnetic entropy change of 1.5 J kg 1 K 1 was observed near 300 K. An appreciable magnetocaloric effect was also observed for a wide range of temperatures near 300K for small magnetic field variation. Heat capacity was measured for temperatures lower than 300K and the adiabatic temperature change increases with increase in temperature with a maximum of 0.62K at 280 K

Mn2þ-induced room-temperature ferromagnetism and spin-glass behavior in hydrothermally grown Mn-doped ZnO nanorods

The magnetic properties of Mn-doped ZnO (ZnO:Mn) nanorods grown by hydrothermal process at a temperature of 200 8C and a growth time of 3 h have been studied. The samples were characterized by using powder X-ray diffraction with Rietveld refinement, scanning electron microscopy, energy-dispersive X-ray analysis and SQUID magnetometry. Mn (3 wt%) and (5 wt%)-doped ZnO samples exhibit paramagnetic and ferromagnetic behavior, respectively, at room temperature. The spin-glass behavior is observed from the samples with respect to the decrease of temperature. At 10 K, both samples exhibit a hysteresis loop with relatively low coercivity. The room-temperature ferromagnetism in 5 wt% Mn-doped ZnO nanorods is attributed to the increase in the specific area of grain boundaries, interaction between dopant Mn2þ ions substituted at Zn2þ site and the interaction between Mn2þ ions and Zn2þ ions from the ZnO host lattice

An Experimental Multimedia Process Control Room

The centralised control rooms of large industrial plants have separated people from the processes they should control. Perception is restricted mainly to the visual sense. Only telephone or radio links provide narrow-band voice communication with maintenance personnel down in the plant. Multimedia equipment can perceptionally bring back the operator into the plant while bodily keeping him the comfortable and safe control room. This involves video and audio transmission from process components as well as sights and sounds artificially generated from measurements. Groupware systems support inter-action between operators, engineers, and managers in different plants. With support from the German government, the state of Hessen, and industrial companies the Laboratory for Systems Engineering and Human-Machine Systems at the University of Kassel establishes an Experimental Multimedia Process Control Room. Core of this set-up are two high-performance graphics workstations linked to one of several process or vehicle simulators. Multimedia periphery includes video and teleconferencing equipment and a vibration and sound generation system.

High-Speed Semiconductor Lasers based on Low-Dimensional Active Materials for Optical Telecommunication

The scope of this work is the fundamental growth, tailoring and characterization of self-organized indium arsenide quantum dots (QDs) and their exploitation as active region for diode lasers emitting in the 1.55 µm range. This wavelength regime is especially interesting for long-haul telecommunications as optical fibers made from silica glass have the lowest optical absorption. Molecular Beam Epitaxy is utilized as fabrication technique for the quantum dots and laser structures. The results presented in this thesis depict the first experimental work for which this reactor was used at the University of Kassel. Most research in the field of self-organized quantum dots has been conducted in the InAs/GaAs material system. It can be seen as the model system of self-organized quantum dots, but is not suitable for the targeted emission wavelength. Light emission from this system at 1.55 µm is hard to accomplish. To stay as close as possible to existing processing technology, the In(AlGa)As/InP (100) material system is deployed. Depending on the epitaxial growth technique and growth parameters this system has the drawback of producing a wide range of nano species besides quantum dots. Best known are the elongated quantum dashes (QDash). Such structures are preferentially formed, if InAs is deposited on InP. This is related to the low lattice-mismatch of 3.2 %, which is less than half of the value in the InAs/GaAs system. The task of creating round-shaped and uniform QDs is rendered more complex considering exchange effects of arsenic and phosphorus as well as anisotropic effects on the surface that do not need to be dealt with in the InAs/GaAs case. While QDash structures haven been studied fundamentally as well as in laser structures, they do not represent the theoretical ideal case of a zero-dimensional material. Creating round-shaped quantum dots on the InP(100) substrate remains a challenging task. Details of the self-organization process are still unknown and the formation of the QDs is not fully understood yet. In the course of the experimental work a novel growth concept was discovered and analyzed that eases the fabrication of QDs. It is based on different crystal growth and ad-atom diffusion processes under supply of different modifications of the arsenic atmosphere in the MBE reactor. The reactor is equipped with special valved cracking effusion cells for arsenic and phosphorus. It represents an all-solid source configuration that does not rely on toxic gas supply. The cracking effusion cell are able to create different species of arsenic and phosphorus. This constitutes the basis of the growth concept. With this method round-shaped QD ensembles with superior optical properties and record-low photoluminescence linewidth were achieved. By systematically varying the growth parameters and working out a detailed analysis of the experimental data a range of parameter values, for which the formation of QDs is favored, was found. A qualitative explanation of the formation characteristics based on the surface migration of In ad-atoms is developed. Such tailored QDs are finally implemented as active region in a self-designed diode laser structure. A basic characterization of the static and temperature-dependent properties was carried out. The QD lasers exceed a reference quantum well laser in terms of inversion conditions and temperature-dependent characteristics. Pulsed output powers of several hundred milli watt were measured at room temperature. In particular, the lasers feature a high modal gain that even allowed cw-emission at room temperature of a processed ridge wave guide device as short as 340 µm with output powers of 17 mW. Modulation experiments performed at the Israel Institute of Technology (Technion) showed a complex behavior of the QDs in the laser cavity. Despite the fact that the laser structure is not fully optimized for a high-speed device, data transmission capabilities of 15 Gb/s combined with low noise were achieved. To the best of the author`s knowledge, this renders the lasers the fastest QD devices operating at 1.55 µm. The thesis starts with an introductory chapter that pronounces the advantages of optical fiber communication in general. Chapter 2 will introduce the fundamental knowledge that is necessary to understand the importance of the active region`s dimensions for the performance of a diode laser. The novel growth concept and its experimental analysis are presented in chapter 3. Chapter 4 finally contains the work on diode lasers.
