Tourism Media Dynamics: Narratives of the Nation-State

With the premise that the tourism promotional video “China, Forever” provides a crucial access to understanding how tourism engages in a wider circle of socio-culture formation, this dissertation research approaches tourism by examining communicative practices initiated by “China, Forever”. In doing so, it seeks to reveal two dialogues – firstly, between the discursive construction of tourism representational language and China’s nation-state ideology; secondly, between interpretations from overseas Chinese audiences and nation-state narratives delivered via the tourism media. In analyzing the first dialogue, this dissertation reveals that the pursuit of collective and monolithic national imagery has caused a representational violence – one that is committed by the nation-state ideology operated through the organization of tourism language. The very representational coercion itself, however, signifies the nature of tourism media as a vehicle mediating the global gaze and China’s self-representation; illuminating the fact that China’s nation-state building is only to be understood as deeply-grounded in the complexity of postcolonial politics. Furthermore, in a dialectic view, such finding consolidates the nature of “China, Forever” as a cultural product that actively exists as a component in the overall social fabric, co-creating a wider circle of culture politics together with other genres of media products; thus, calling for a more comprehensive understanding of tourism media at large. In the second approach, this dissertation seeks to understand how the tourism video “China, Forever” mediates the relationship between tourism narratives of the nation-state and overseas Chinese individuals; thus bridging together tourism media and ongoing life experiences of the audiences chosen. The analysis reveals that audiences’ interpretations heavily concentrate on resisting and fragmenting the hegemonic nation-state language in “China, Forever”. While some interviewees seek to decentralize the nation-state perspective from aspects of aesthetics, representational style, and representational subjects in “China, Forever” by incorporating their individual memories and past experiences, to some others, the over-polished glorification of China in the mediated tourism discourse is only coercive to China’s social realities experienced by the individual interviewees - the disheartening contrasts of poverty and affluence as well as other social inequalities. From the perspective of the audience group, the Chinese scholars and students at the University of Illinois interviewed for this dissertation research constitute a cohort of exiled audiences for the tourism video “China, Forever”. The audiences subject themselves to voluntary interpellation, a process in which they find themselves defending, negotiating, and resisting the nation-state representation of China – even though they are not its intended audience and have had no input into its production. Nevertheless, such process is one of identification, in which viewers articulate a subject position from which to speak of their own experiences, dilemmas and desires. The usefulness of tourism media discourse in mediating the nation-state narratives and the individual experience is amplified.

Rôle de la qualité des tapis de cellules endométriales en co-culture autologue sur le développement embryonnaire

Introduction : La fécondation in vitro est de mieux en mieux connue et en amélioration constante, cependant les taux d’implantation et de grossesse sont encore bas (environ 35% par fécondation in vitro). Un des enjeux de l’amélioration de la fécondation in vitro est le développement embryonnaire et l’implantation. Pour cela, la co-culture des embryons sur un tapis de cellules endométriales maternelles autologues peut être utilisée pour améliorer le développement embryonnaire (taux d’embryon se développant jusqu’à J5 : blastocyste) et l’implantation. L’objectif de l’étude est d’étudier le lien entre la qualité du tapis cellulaire et le développement embryonnaire. Matériel et méthodes : Cette étude est une sous analyse de l’essai clinique randomisé en double aveugle OvoGen, comparant le taux de blastulation et de grossesse dans deux groupes randomisés : le groupe étude, dans lequel les embryons se développent sur un tapis cellulaire endométrial maternel et le groupe contrôle, dans lequel les embryons sont cultivés dans du milieu conventionnel. Nous avons analysé la qualité des tapis cellulaire du groupe étude (confluence des cellules, taux de cellules épithéliales et vitalité des cellules stromales) par rapport au développement embryonnaire et au taux de grossesse. Résultats : 50 tapis de cellules endométriales maternelles et 291 embryons sur les puits ont été analysés de 2012 à 2015 à la clinique ovo (Montréal, Québec). La qualité des embryons n’était pas changée par la qualité des tapis (p=0,65 pour la confluence, p=0,25 pour le taux de glande et p=0,92 pour la viabilité des cellules). En revanche, le taux de grossesse augmentait quand la confluence diminuait (p=0,022) et lorsque la viabilité des cellules stromales augmentait (p=0,001). De plus, la qualité des tapis était dépendante de la date de la biopsie : la biopsie faite à J7 après l’ovulation permettait une meilleure qualité de puits (confluence augmentée, p=0,045, taux de glande augmenté p=0,004 et viabilité stromales augmentée p=0,001) que la biopsie faite à J5 post ovulation. Discussion : Aucune des nombreuses études sur la co-culture ne porte sur la qualité des tapis cellulaire. Il est intéressant de noter que le taux de grossesse augmente avec la diminution de la confluence et l’augmentation de la viabilité des cellules stromales dans les puits contenant les embryons transférés. Comme il a déjà été démontré, (1)le jour de la biopsie endométriale influe sur la qualité du tapis cellulaire en coculture et pour que celui-ci soit de bonne qualité, il faut que l’endomètre soit réceptif (après J19 du cycle). Conclusion : Nous avons montré que la qualité des tapis cellulaires dépendait du jour de la biopsie d’endomètre et que cette qualité pouvait influencer le bénéfice de la co-culture. Il serait intéressant d’étudier la réceptivité de l’endomètre au moment de la biopsie avant utilisation des cellules en co-culture pour optimiser la qualité du tapis cellulaire.

YouTubers as satirists: humour and remix in online video

This article aims to discuss the role humour plays in politics, particularly in a media environment overflowing with user-generated video. We start with a genealogy of political satire, from classical to Internet times, followed by a general description of “the Downfall meme,” a series of videos on YouTube featuring footage from the film Der Untergang and nonsensical subtitles. Amid video-games, celebrities, and the Internet itself, politicians and politics are the target of such twenty-first century caricatures. By analysing these videos we hope to elucidate how the manipulation of images is embedded in everyday practices and may be of political consequence, namely by deflating politicians' constructed media image. The realm of image, at the centre of the Internet's technological culture, is connected with decisive aspects of today's social structure of knowledge and play. It is timely to understand which part of “playing” is in fact an expressive practice with political significance.

Transvase : quando a ficção invade a realidade

ABSTRACT: Adopting the concept of metalepsis, as explained by Gérard Genette, I intend to tackle the miscegenation of ontological worlds as practiced in metacinematic films dealing either with the creator or the spectator and made famous with Woody Allen’s film The Purple Rose of Cairo (1985, EUA). Assuming the existence of two adjoining fictional universes, one of them intrafilmically projected onto a screen and the other positioned in front of it so as to create or observe the other, one realizes that, in fact, they both communicate in a more intense way. That is, they both can cross the barrier that separates them and function, literally, as communicating vessels thrusting themselves onto the other side of fiction. The use of this screen passage technique – which I call ‘spilling narrative’ – although it takes place inside the film, at an intradiegetic level, cannot be considered a simple comic effect. In actuality, it is a very serious affair, denoting the authorial intervention as a reflexive practice of écriture by means of a mise en abyme, according to Lucien Dällenbach. Therefore, the fictional spilling over of worlds which totally blends together both sides of the twice artificial universe of the fabula, represents the emotional and intellectual involvement of the creator with his/her creation and of the spectator with the world watched. Both illustrate the desire of fusion inherent in the acts of creation and reception. My approach will be based on Gabriele Salvatores’ Happy Family (2010) and Wojciech Marczewski’s Escape from the ‘Liberty’ Cinema (1990).

Dermatophytosis caused by Trichophyton raubitschekii. Report of the first case in São Paulo, Brazil

The authors report the first case of dermatophytosis caused by Trichophyton raubitschekii in a patient from the State of São Paulo with Tinea corporis lesions localized on the buttocks. Culture on Sabouraud-agar with cycloheximide permitted the isolation and identification of the fungus, and the diagnosis was confirmed by Dr. Lynne Sigler, University of Alberta, Canada. Systemic treatment with fluconazole, 150 mg/week for 4 weeks, in combination with topical treatment with isoconazole initially yielded favorable results, with recurrence of the lesions after the medication was discontinued. This is the fifth case of this dermatophytosis published in the Brazilian medical literature.

Evaluation of pathogenic fungi occurrence in traumatogenic structures of freshwater fish

INTRODUCTION: Fungal infections in human skin, such as sporotrichosis, can occur after fish induced trauma. This work aimed to identify fungi in freshwater fish that are pathogenic to humans. METHODS: Extraction of dental arches from Serrassalmus maculatus (piranha) and Hoplias malabaricus (wolf fish), stings from Pimelodus maculatus (mandis catfish), dorsal fin rays from Plagioscion spp. (corvina) and Tilapia spp., for culture in Mycosel agar. Some cultures were submitted to DNA extraction for molecular identification by sequencing ITS-5.8S rDNA. RESULTS: Cultures identified most yeast as Candida spp., while sequencing also permitted the identification of Phoma spp. and Yarrowia lipolytica. CONCLUSIONS: While the search for S. schenckii was negative, the presence of fungus of the genera Phoma and Candida revealed the pathogenic potential of this infection route. The genus Phoma is involved in certain forms of phaeohyphomycosis, a subcutaneous mycosis caused by dematiaceous fungi, with reports of infections in human organs and systems. Traumatizing structures of some freshwater fish present pathogenic fungi and this may be an important infection route that must be considered in some regions of Brazil, since there are a large number of a fisherman in constant contact with traumatogenic fish.

Experimental infection with Leishmania (Viannia) braziliensis, and Leishmania (Leishmania) amazonensis in the marmoset, Callithrix penicillata (Primates: Callithricidae)

Foureen marmosets (Callithrix penicillata) were inoculated intradermally with promastigotes and/or amastigotes of Leishmania (Viannia) brazilensis (L. (V) b.) strains MHOM/BR/83/LTB-300MHOM/BR/85/LTB-12 MHOM/BR/81/LTB-179 and MHOM/BR/82/LTB-250. The evolution of subsequent lesions was studied for 15 to 75 weeks post-inoculation (PI). All but of the L. (V) b. injected marmosets developed a cutaneous lesion at the point of inoculation after 3 to 9 weeks, characterized by the appearance of subcutaneous nodules containing parasites. parasites were isolated by culture (Difco Blood Agar) from all 11 positive animals. The maximum size of the lesions was variable and ranged between 37 mm² to 107 mm². Ulceration of primary nodules became evident after 3 to 12 weeks in all infected marmosets, but was faster and larger in 5 of the 11 animals. The active lesions persisted in 9 out of 11 Callithrix until the en of the observation period, which varied from 15-75 weeks. In 3 animals spontaneous healing of their lesions (13 to 25 weeks, PI) was observed buth with cryptic parasitism. In another 2 infected animals there was regression followed by reactivation of the cutaneous lesions. The appearance of smaller satellite lesions adjacent to primary ones, as well as metastatic lesions to the ear lobes, were documented in 2 animals. Promastigotes of L. (Leishmania) amazonensis (L.(L)a.) MHOM/BR/77/LTB-16 were inoculated in 1 marmoset. This animal remained chronically infected for 6 months and the lesions developed in a similar manner to L.(V)b. infected marmosets. No significant differences in clinical and parasitological behaviour were observed between promastigote or amastigote derived infections of the 2 species. Both produced chronic, long lasting lesions which eventually healed. The same was true for parameters of size and ulceration. Skin tests converted to parasite in 11 of 15 inected masmosets and in 10 of 12 parasite positive animnals. Moderate levels of circulating antibodies were also observed by IFAT /IgG assays. In spite of the failure to reproduce the mucosal form of the disease, an important aspect of the Callithrix model in experimental cutaneous leishmaniasis lies in the reproduction of 2 clinical events that are common in humans, namely, the chronic ulceration and spontaneous healing of the lesions.

Työn ja muun elämän yhteensovittaminen ja sen sukupuolittunut ulottuvuus: analyysi mediateksteistä

Tutkimuksen tarkoituksena on selvittää, miten mediatekstit kuvaavat naisten ja miesten työn ja muun elämän yhteensovittamista. Tavoitteena on tutkia sitä, miten media rakentaa ja uusintaa suomalaisessa yhteiskunnassa vallitsevia sukupuolikäsityksiä ja stereotypioita työn ja muun elämän yhdistämistä käsittelevissä lehtiteksteissä. Lisäksi tavoitteena on analysoida sitä, minkälaisia merkityksiä mediatekstit synnyttävät työstä ja yksityiselämästä. Tutkimus on luonteeltaan laadullinen ja tutkimusmetodina on käytetty diskurssianalyysia. Tutkimusaineisto koostuu 17 suomalaisesta lehtitekstistä. Tekstien valinnassa oli tärkeää se, että ne käsittelevät työn ja muun elämän yhteensovittamista mahdollisimman monipuolisesti. Tutkimustulokset osoittavat, että media uusintaa olemassa olevia sukupuolikäsityksiä työn ja muun elämän yhteensovittamisessa.Lisäksi kävi ilmi työn tekemisen arvostaminen. Muu elämä rakennetaan pääsääntöisesti työssäkäynnin ympärille, vaikka mahdollisuuksia omaan aikaan ja yksityiselämään pidetään hyvin tärkeinä. Yhteiskunnan arvot ja kulttuuri ovat mediatekstien luoman kuvan taustalla. Tämä sanelee osaltaan sen, miten sukupuolta työn ja muun elämän yhteensovittamisessa on lehdissä käsitelty.

Detection of drechslera avenae in oat seeds

The fungus Drechslera avenae, the causal agent of Helminthosporium leaf spot on oats (Avena sativa), survives as mycelium in crop residues and in infected seeds. In trials carried out in the laboratory, ten methods were evaluated for their efficiency to detect D. avenae in oat seeds. In each experiment, groups of two or three methods were compared to a standard protocol, in which seeds were placed in Petri dishes containing the Reis selective medium and incubated at 25±2 °C for ten days. Data were submitted to analysis of variation and the means of the methods were compared using the Dunnett test at the 5% significance level. Overall, the highest levels of seed infection by D. avenae were observed on oat seeds plated in the osmotic, the oat-agar and the Reis media, or on seeds subjected to heat treatment previous to incubation in malt-agar. Therefore, these methods should be recommended for detection of D. avenae in oat seed testing.

Respuestas morfológicas y anatómicas de Tessaria absinthioides (Hook. et Arn.) DC. a la salinidad

T. absinthioides, Inuleae, Compositae, is a weedy species that is spreading in the irrigation area of the Colorado River, Argentina. This species can be found in normal and saline soils. Morphological and anatomical variables were measured with two salts, sodium chloride and sodium sulfate, with three levels of osmotic potential -0.4, -0.8 and -1.5 MPa, in hydroponic culture, using Hoagland solution as the cultivation media. The total diameter of the roots of plants growing in Na2SO4 and NaCl increased when the osmotic potential was -0.4 MPa. In plants growing in NaCl this may have resulted from the increase in the size of the cortical cells and in plants growing in Na2SO4, the diameter increased may be due to an increase in the cambial activity. The number and length of shoot internodes decreased with increasing salinity, even though this was not statistically significant. In comparison to the control, the total diameter of the shoot increased at -0.4 MPa and decreased with the reduction of the osmotic potential. In comparison to the control, the length of the leaves decreased at -0.4 MPa and the leaves width increased at the same concentration. The palisade parenchyma appeared less developed in saline conditions. In comparison to the control, the number of hairs increased at -0.4 MPa. T. absinthioides acts as a semihalophytic species, according to the salt ranks it tolerates. The mechanisms of adaptation to saline conditions are succulence in root and stunted growth if the salt in the media is NaCl, and the production of haloxeromorphic characters if the salt in the media is Na2 SO4

Effect of conditioned medium of mesenchymal stem cells on the in vitro maturation and subsequent development of mouse oocyte

Mesenchymal stem cells (MSCs) secrete a variety of cytokines and growth factors in addition to self-renewal and multiple forms of differentiation. Some of these secreted bioactive factors could improve meiotic maturation in vitro and subsequent embryo developmental potential. The aim of the present study was to determine whether in vitro maturation (IVM) of mouse oocyte with or without cumulus cells could be improved by contact with conditioned medium (CM) of MSCs as well as the efficiency of CM to support follicular growth and oocyte maturation in the ovarian organ of mice cultured on soft agar. The developmental potential of matured oocyte was assessed by blastocyst formation after in vitro fertilization (IVF). Germinal vesicle stage oocytes with or without cumulus cells were subjected to IVM in either CM, Dulbecco's modified Eagle's medium (DMEM), α-minimum essential medium (α-MEM) or human tubal fluid (HTF). Approximately 120 oocytes were studied for each medium. CM produced a higher maturation rate (91.2%) than DMEM (54.7%), α-MEM (63.5%) and HTF (27.1%). Moreover, CM improved embryo development to blastocyst stage significantly more than DMEM and HTF (85 vs 7% and 41.7%, respectively) but there was no significant difference compared with α-MEM (85 vs 80.3%). The behavior of cortical granules of IVM oocytes cultured in CM revealed cytoplasmic maturation. Moreover, CM also supported preantral follicles growth well in organotypic culture on soft agar resulting in the maturation of 60% of them to developmentally competent oocytes. The production of estrogen progressively increased approximately 1-fold every other day during organ culture, while a dramatic 10-fold increase in progesterone was observed 17 h after human chorionic gonadotropin stimulus at the end of culture. Thus, CM is an effective medium for preantral follicle growth, oocyte maturation, and sequential embryo development.
