摘要 隨著時代變遷，行銷手法愈來愈推陳出新，商品零售市場的競爭也愈來愈激烈，走進零售店會看到二件八折，第二件五折或是買一送一等降價促銷活動；剛開始做第二件五折的時候，業績瞬間成長，但是多做幾次之後，效益可能就開始往下降，因此可能開始加碼做買一送一，或是增加降價促銷的頻率，最後無法抽身，而陷入一個不得不做的僵局。所以，如何訂定適當的行銷策略，在價格促銷深度和頻率間取得平衡點，追求最大的效益，是製造商常常面臨的問題與決策。 本研究使用尼爾森量販店商品掃描資料，以餅乾銷售資料做為研究品類，探討價格促銷深度與頻率的相互關係，如何影響消費者購買趨勢。本研究根據迴歸線性模型，利用銷售資料先了解前期、節慶及競爭者等變數對該品類的影響，再分析不同的促銷折扣下的價格彈跳幅度，最後分別以二個月及三個月為單位搭配促銷的頻率，看前期有無促銷的時候，對最後一個月不同的價格促銷深度時的業績增加幅度影響。 最後以消費者預期下一次促銷時間與預期價格差異的行為理論，針對本研究結果做分析，提供行銷建議。

兩種語句處理模型曾被提出以解釋閱讀句子時語法及語意資訊的互動。句法優先模型(syntax-first models)認為詞性判斷必定先於語意分析，而制約滿足模型(constraint-satisfaction models)則認為不同的資訊在語句理解的過程中會同時被處理。本研究檢驗兩種語句處理模型能否解釋語句中的詞彙歧義解困(lexical ambiguity resolution)。 許多眼動研究曾發現詞彙歧義詞的次要語義偏向效應(subordinate bias effect)，顯示語意偏向次要語義的語境能加速激發歧義詞的次要語義並且產生語義競爭。然而，語境的語法在詞彙歧義解困中扮演的角色並不清楚。因而，不同語義分屬不同詞性的詞性歧義詞便提供我們一個媒介以檢驗詞彙歧義解困中詞性及語意限制的互動。 本研究的目的有二：(一) 檢驗詞性限制能否決定中文詞性歧義詞的語義解困；(二) 檢驗中文歧義詞語義的詞性是否會影響次要語義偏向效應。實驗一我們將四種不同類型的中文非均勢同形異義詞置於語法及語意皆為次要語義偏向的句子裡；實驗二則將四種不同類型的中文非均勢同形異義詞置於語法為次要語義偏向但語意中立的句子裡。受試者閱讀句子時的眼動表現會即時被記錄。 實驗一的結果發現：(一) 四類型歧義詞的次要語義偏向效應只反映在目標詞後區域的二次閱讀指標上；(二) 就效果量而言，NV歧義詞的次要語義偏向效應在目標詞及目標詞後兩個區域都比VN歧義詞來得大。實驗二的結果則發現：(一) VN歧義詞的次要語義偏向效應從目標詞區的首次閱讀指標就出現，並且持續至目標詞及目標詞後兩個區域的二次閱讀指標；(二) 另外三類型歧義詞的次要語義偏向效應直到所有分析區域的二次閱讀指標才反映出來；(三) NV歧義詞的次要語義偏向效應比VN歧義詞出現得更晚也更不明顯。整體而言，本研究的結果顯示詞性限制並不是影響中文詞性歧義詞語義解困的唯一因素。此結果支持制約滿足模型，並反對句法優先模型的預測。 / Two primary sentence processing models have been proposed to account for the interaction between syntactic and semantic information in reading sentences: Syntax-first models assume that syntactic-category assignment must precede semantic analysis, while constraint-satisfaction models propose that information from different sources is processed and weighed at the same time during sentence comprehension. The present study examined whether these sentence processing models, which assume different contribution of syntactic category and semantic context, can explain the resolution of lexical ambiguity in sentences. Several eye movement studies have demonstrated the subordinate bias effect (SBE) for lexical-semantic ambiguous words (i.e., NN/VV homographs), indicating that a subordinate-biased semantic context can boost the activation of the subordinate meaning of ambiguous words and causes meaning competition (Duffy, Morris, & Rayner, 1988). However, the role of syntactic context in lexical ambiguity resolution is less clear. Syntactic category ambiguous words (i.e., SCA words; VN/NV homographs), whose alternative meanings differ in syntactic category (e.g., watch in English), serve as a means of examining the interaction between syntactic category and semantic constraints during lexical ambiguity resolution. The purpose of the present study was twofold: (a) to examine whether the syntactic category constraint can determine the semantic resolution of Chinese SCA words, and (b) to investigate whether syntactic category of alternative meanings of Chinese homographs can influence the SBE during lexical ambiguity resolution. Four types of Chinese biased homographs (NN, VV, VN, and NV) were embedded into syntactically and semantically subordinate-biased sentences (Experiment 1) and into syntactically subordinate-biased but semantically neutral sentences (Experiment 2). Participants’ eye movements were recorded as they read each sentence. In Experiment 1, the results showed: (1) The SBE for the four types of homographs was significant only in the second-pass reading on the post-target words. (2) Numerically, the NV homographs revealed a larger effect size of SBE than VN homographs on both target and post-target words. In Experiment 2, the results showed: (1) The SBE for VN appeared from the first-pass reading on the target words and lasted to the second-pass reading on the target and post-target words. (2) The SBE for the other types of homographs did not occur until the second-pass reading in all analyzed regions. (3) The SBE for NV occurred much later and less obviously than that for VN. In general, our findings support the constraint-satisfaction models and reject the prediction of the syntax-first models, suggesting that the syntactic category constraint is not the only factor influencing the semantic resolution of SCA words.

La crise économique du début des années 90 a profondément modifié le système de distribution français. La montée en puissance des "hard discounters", conjuguée au très fort développement des produits "premiers prix", a eu pour conséquence majeure d'intensifier la concurrence entre marques nationales et marques de distributeurs. Cette dernière s'est encore trouvée accrue par une utilisation de plus en plus fréquente de la promotion par ces deux groupes de marques. Jusqu'à présent, la grande majorité des recherches sur la promotion des ventes a été effectuée au niveau de la référence, ou de la marque. Or les distributeurs gèrent des catégories de produits dont l'assortiment se compose aujourd'hui de trois grands groupes - les marques nationales, les marques de distributeurs et les premiers prix - groupes de marques qui présentent des intérêts et problématiques différenciés. Les distributeurs sont donc intéressés, en priorité, dans l'analyse des promotions, par les effets qu'elles peuvent avoir sur les ventes totales de la catégorie et sur sa structure concurrentielle. Nous développons, dans cette thèse, un outil méthodologique qui a pour objectif de mesurer les effets promotionnels à des niveaux d'analyse agrégés: la catégorie de produits et le groupe de marques (marques nationales, marques de distributeurs, ou premiers prix) .. Cet outil permet d'analyser les effets à court terme d'une promotion particulièrement importante - la mise en avant - sur : 1- les ventes totales de la catégorie de produits, 2- les rapports concurrentiels entre les groupes de marques qui la constituent et, plus spécifiquement, entre les marques nationales et les marques de distributeurs. Grâce à cet outil, nous sommes en mesure d'apporter, pour chaque catégorie de produits étudiée, des réponses aux questions suivantes : 1- les mises en avant augmentent-elles les ventes totales de la catégorie? 2- ces augmentations, si elles existent, sont-elles différentes suivant le groupe de marques promu? 3- les mises en avant constituent-elles des outils efficaces pour modifier la structure concurrentielle intra-catégorie entre marques nationales et marques de distributeurs ? 4- les effets entre les deux groupes sont-ils asymétriques, comme le suggère la théorie des niveaux de prix de Blattberg et Wisniewski (1989) ? Cette méthodologie permet en outre de confirmer que les effets promotionnels varient de catégorie à catégorie et d'enseigne à enseigne.

This dissertation analyses the formation of Swedish cultural policy in the twentieth century and the emergence of a modern concept of cultural policy. The aim is to historicise this concept by opening up the process through which it was established. The dissertation explores different aspects of this process: the use of the word cultural policy (kulturpolitik), the ambitions in the 1960s to establish a form of knowledge production relevant in cultural policy making and the attempts made by various official authorities in the 1960s and early 1970s to identify and manage the field of concerns defined as belonging to cultural policy, thus demarcating culture as a formal area of policy making. I view these as examples of practices where the category of cultural policy was elaborated and established in a form widely recognized today. Accompanying my attempts to historicise the modern concept of cultural policy is an interest in how the history of cultural policy has generally been conceived. In previous research devoted to the history of cultural policy an analytical sense of cultural policy has tended to overrule the understanding(s) of cultural policy found in the historical sources. As a consequence, the histories of cultural policy have left out what historically was identified as cultural policy, thus leaving the historical grounds for the modern concept of cultural policy partly hidden. In the first empirical chapter I examine the uses of the word cultural policy when it was introduced in the Swedish language in the late nineteenth century until the 1950s. From a multitude of usages, I suggest that it was in the mid-twentieth century that a more consistent vocabulary developed, with “cultural policy” referring to political endeavors aiming at a nation’s domestic cultural life. In the second empirical chapter I investigate how scientific conceptualisations and operationalisations rendered culture available for scientific, political and administrative undertakings, and in the third chapter I study how culture was demarcated as a formal area of policy making. The chapters reveal different aspects of the historical process through which the category of cultural policy was established in its present shape.

La présente thèse reprend trois articles de recherche (deux études et un article de revue) portant sur les neurosciences cognitives du langage, chacun desquels a été écrit en vue d’identifier les bénéfices que la théorie (neuro)linguistique contemporaine pourrait tirer d’une étude exhaustive des processus cognitifs et neuraux sous-tendant les troubles du spectre autistique (TSA) et inversement. Deux études y sont présentées, utilisant la méthode des potentiels évoqués, lesquelles fournissent des preuves préliminaires, chez des individus typiques, de deux aspects de la compréhension de phrases nécessitant une recherche approfondie chez des personnes autistes : (1) Les corrélats neuraux de la nature syntaxique et sémantique particulière des verbes d’expérience (par exemple The girl has feared the storm) contrairement aux verbes d’action (par exemple The kids have eaten the fries) et leur interface potentielle avec la Théorie de l’Esprit – la capacité d’attribuer des états mentaux à soi et à autrui – pour laquelle les personnes autistes semble accuser un retard et/ou un déficit, et (2) les corrélats neuraux des compétences en « imagerie visuelle », telles quelles sont identifiées à l’aide des Matrices de Raven, sur les processus de détection de violations de catégories grammaticales (par exemple He made the meal to enjoy with friends/He made the enjoy to meal with friends) dans un paradigme expérimental “équilibré” et en modalité visuelle. L’article de revue cherche à fournir une perspective plus large du rôle que les neurosciences cognitives des TSA peuvent jouer dans l’étude biologique du langage. L’importance de considérer l’autisme comme un « style cognitif » plutôt qu’un trouble en soi y est défendue, en particulier contre la notion commune d’autisme en tant que déficit de Théorie de l’Esprit. Au delà de leurs perspectives potentielles de recherche future auprès de populations autistes, ces trois articles cherchent à répondre à plusieurs questions de recherche cruciales sur le développement et la compréhension du langage (c’est à dire le débat sur la «P600 sémantique», les théorie d’échantillonnage asymétrique de la perception de la parole et de la musique, le rôle de la vision dans le langage, la modularité, les styles cognitifs et l’inférence Bayesienne). / The present thesis comprises a set of three research articles (two studies and one review article) on the cognitive neuroscience of language, all of which were written with the purpose of understanding the benefits that contemporary (neuro)linguistic theory may draw from an extensive study of the cognitive and neural processes underlying Autism Spectrum Disorders (ASD) and vice versa. Two studies are presented, using event-related brain potentials, which provide preliminary evidence in typical individuals for two aspects of sentence processing in need of future investigation in ASD participants: (1) The neural correlates of the peculiar syntactic and semantic nature of verbs of experience (Experiencer Subject verbs, i.e., The girl has feared the storm) as opposed to verbs of action (Agent Subject verbs, i.e., The boys have eaten the fries) and their potential interface with Theory of Mind – the ability to attribute mental states to self and others – known to present delays and impairments in autism, and (2) the neural correlates of “visual imagery” skills, as assessed through the Raven Matrices, on comprehenders’ ability to detect word category violations (e.g., He made the meal to enjoy with friends/He made the enjoy to meal with friends) in a balanced visual paradigm and their potential insights into the role of visual imagery in language comprehension, known to play a potentially predominant role in ASD. The review article attempts to provide a larger perspective on the role of the cognitive neuroscience of ASD in the biology of language, in which the importance of considering autism as a “cognitive style” rather than as a disorder is given greater value, especially relative to the common notion of autism solely as a Theory of Mind impairment. Aside from their potential prospects for future research in autistic populations, these three articles also attempt to frame their topic of inquiry into the broader context of contemporary research questions on language development and language comprehension, such as the role of animacy in language processing (the “semantic P600” debate), asymmetric sampling theories of speech and music perception, the role of vision in language, modularity, cognitive styles or Bayesian inference. / VERSION ANGLAISE DISPONIBLE AU DÉPARTEMENT; THÈSE RÉALISÉE CONJOINTEMENT AVEC L'ÉCOLE DES SCIENCES DE LA COMMUNICATION DE L'UNIVERSITÉ MCGILL (DRS.

Die seit 2004 in Deutschland bekannt gewordenen Fälle der illegalen Rückführung und irrtümlichen Fehlverbringung von gemäß der Verordnung (EG) Nr. 1774/2002 nicht für den Genuss durch den Menschen bestimmten tierischen Nebenprodukten (TNP) der Kategorie 3 in die Lebensmittelkette haben zu der politischen Diskussion beigetragen, ob die Pflicht der Materialidentifizierbarkeit durch das Getrennthalten TNP am Ort des Anfalls sowie die ausschließliche Kennzeichnung ihrer Transportbehälter bei der Beförderung einen ausreichenden Schutz der Verbraucher garantieren können. Um eine ordnungsgemäße Verwendung TNP der Kategorie 3 sicherzustellen, hat der Bundesrat ihre unmittelbare und eindeutige Kennzeichnung, z.B. durch Farbstoffe, gefordert. Ziel dieser Arbeit war es, einen geeigneten, futtermittelrechtlich zugelassenen Marker für Schlachtnebenprodukte der Kategorie 3 zu erörtern, der eine technisch praktikable, vom Ort des Anfalls bis zum Verarbeitungsbetrieb optisch eindeutige, dauerhafte und nach der Verarbeitung nachweisbare sowie umwelt- und wirtschaftsverträgliche Markierung von Schlachtnebenprodukten zur sicheren Verfolgbarkeit ihrer bestimmungsgemäßen Verwendung als TNP der Kategorie 3 ermöglicht, um ihren Eintrag in die Lebensmittelkette zu unterbinden, ohne die Neutralität der Endprodukte bei der Verwendung markierter TNP als Rohstoffe für Futtermittel zu beeinträchtigen. Für die Markierung von Schlachtnebenprodukten mittels Sprühsystemen wurden für Futtermittel zugelassene, färbende Zusatzstoffe (Verordnung (EG) Nr. 1831/2003) sowie in der medizinischen Diagnostik etablierte Fluoreszenz-Farbstoffe ausgewählt und hinsichtlich der Eindeutigkeit ihrer Markierung, ihrer Farbhaltung nach Bearbeitung sowie ihrer optischen Neutralität in Lebens- und Futtermitteln, die aus markierten TNP hergestellt worden sind, von fünf ungeschulten Prüfpersonen im Rahmen einer einfach beschreibenden, sensorischen und unabhängigen Prüfung gemäß §35 LMBG (L 00.90-6, ASU) beurteilt. Die Ergebnisse der sensorischen Prüfung wurden mit den RGB-Farbprofilen der markierten und nicht markierten TNP vergleichend analysiert. Zum Nachweis des irrtümlichen oder vorsätzlichen Eintrags von mit den ausgewählten Markerfarbstoffen markierten TNP in Lebensmitteln konnten die Analyseverfahren Dünnschichtchromatographie (DC), optische Emissionsspektrometrie mit induktiv gekoppeltem Hochfrequenzplasma (ICP-OES), Photometrie sowie die Fluoreszenzspektrometrie hinsichtlich ihrer Anwendbarkeit untersucht werden. Die Untersuchung der sensorischen Neutralität der Markerfarbstoffe im Endprodukt Futtermittel erfolgte unter anderem durch einen Futtermittelpräferenzversuch an neun Hunden der Rasse Beagle. Brillantsäuregrün E142 (1,3 mg E142/kg TNP) konnte auf Grund der Eindeutigkeit der Markierung von Schlachtnebenprodukten durch die gegenüber den nativen TNP signifikant unterschiedlichen Rot-Farbintensitäten bei gleichzeitiger Neutralität in den Endprodukten (Lebens- oder Futtermittel) und einer guten bis sehr guten Farbhaltung nach dem Waschen der Nebenprodukte, der Kühl- (8°C über zwei Tage) sowie Gefrierlagerung (-25°C über 14 Tage) und dem Verwenden einer 14, 90 als auch 150 Tage gelagerten Farbstofflösung in Kombination mit dem chemisch nachweisbaren Titandioxid (90 mg E171/ kg TNP) als Markerfarbstofflösung zur eindeutigen Markierung von Nebenprodukten der Schlachtung am Ort ihres Anfalls selektiert werden. Die für die Markierung bestimmten Dosierungen der Markerfarbstoffe gelten für Tiere und Menschen als unbedenklich. Die mit den färbenden Zusatzstoffen E142 und E171 markierten Nebenprodukte der Schlachtung können mittels DC (Nachweisgrenze: ≥7,5 µg E142/kg Probe) beziehungsweise ICP-OES und Photometrie (Nachweisgrenze ICP-OES: 8,3 mg E171/kg Probe) ab einem eingebrachten Anteil von 0,55% (DC: E142) beziehungsweise 9% (ICP-OES: E171) in diversen Produkten (Lebens- oder Futtermittel) nachgewiesen werden. In den chemisch und thermisch extrahierten Fetten aus markierten, fettreichen TNP waren die Farbstoffe E142 und E171 jedoch nicht nachweisbar. Eine Fluoreszenzmarkierung TNP kann hingegen nicht präferiert werden, da nicht markierte Nebenprodukte der Schlachtung eine sichtbare und fluoreszenzspektrometrisch nachweisbare Autofluoreszenz aufweisen und in den thermisch verarbeiteten Produkten keine für die Fluoreszenz-farbstoffe charakteristischen Absorptions- und Emissionsspektren nachweisbar waren. Die Markierung mittels Sprühtechnik erscheint unter den Aspekten Substanzverlust und adaptierter Markerfarbstoff pro Kilogramm TNP praktikabel. Die im Labor bestimmte Markierungszeit für TNP (5 sec./kg) ist unter Einbeziehung der Durchsatzraten am Schlachthof als zu lang zu bewerten. Durch die rückstandsfreie Entfernung der Farbstoffe von Edelstahl- und glatten Kunststoffflächen sowie glasierten Fliesen ergeben sich keine Nachteile der Markierung TNP für die Produktion von Futtermitteln und technischen Erzeugnissen. Die in dem Präferenzversuch untersuchten Futtermittel für Hunde aus markierten TNP zeigten keine Abweichungen von der handelsüblichen sensorischen Produktqualität und hinsichtlich ihrer Haltbarkeit durch Sterilisation (F0-Wert). Mit E142 und E171 markierte TNP (Kat. 3) eignen sich somit als Rohstoffe zur Herstellung von Heimtierfuttermitteln. Bei Anwendung einer Kombinationsfarbstofflösung (E142 und E171) würden die für die Marker anfallenden Kosten pro Tonne TNP bis zu 33 Euro betragen. Bei der ausschließlichen Verwendung von E142, welches der optisch eindeutig markierende Farbstoff ist und das eine hohe Sensitivität im dünnschichtchromatographischen Nachweis zeigt, würden die Kosten 1,70 bis 3,40 Euro/t betragen. Bisher konnte kein EU-einheitlicher Rechtsrahmen zur Markierung TNP der Kategorie 3 gestaltet werden. Die politische Diskussion wird aber vor allem national fortgesetzt. / Since 2004 several illegal or aberrant transfers of animal by-products (ABP) from category 3 (according to Regulation (EC) No. 1774/2002: not intended for food production) back into food chain, have led to the political discussion, whether duty of material identifiability by separate storing of ABP on site and sole labeling of containers during transport are sufficient to protect consumers from ABP not intended for human consumption. To guarantee adequate utilisation of ABP from category 3, the German Federal Council claimed for an immediate and conclusive marking of ABP by dyeing or similar solutions. This study was implemented to define a convenient, registered feed additive for dyeing of slaughter by-products from category 3, which realize a feasible, from extraction to processing visually conclusive, long-lasting, traceable as well as sustainable and cost-effective marking on site to ensure traceability of intended utilisation as ABP from category 3 and to prevent their influx into food chain, without an impairment of the neutrality of products (e.g. pet food) made from marked ABP. For marking of slaughter by-products by air spraying device, registered colouring feed additives (Regulation (EC) No. 1831/2003) as well as diagnostically established fluorescence pigments were selected and investigated regarding their marking unambiguousness, colour retention after processing and visual neutrality in food and feed made from marked ABP by evaluation of five untrained judging persons in the course of a simply delineative, sensorial and impartial test (official list of analysis methods, ASU §35 LMBG, L 00.90-6), and by comparative RGB-colour measurement of images scanned from stained ABP samples. Detection of aberrant or deliberate discharge of marked ABP into food production was evaluated by investigation of thin layer chromatography (TLC), inductively coupled plasma optical emission spectrometry (ICP-OES), photometry and fluorescence spectrometry. Neutrality of marking feed additives in feedstuff was determined by a feeding preference test with nine dogs of the Beagle breed using pet food made from unmarked und marked ABP. Lissamine Green E142 (1,3 mg E142 per kg ABP) was selected as marker dye for slaughter by-products on site based on its unambiguousness of marking due to the significant different red-colour intensity compared to the non-marked ABP as well as the simultaneous neutrality of the colouring additive E142 in the final products feed and food. Colour retention of E142 marking was conclusive with regard to handling by washing, cold (8°C for two days) respectively fridge storage (-25°C for 14 days) and utilisation of a 14-, 90- and 150-days-stored marker solution. For marking, Lissamine Green was combined with the chemical detectable and registered food colour titanium dioxide (E171: 90 mg/kg ABP). The marker additives are classified as safe for humans and animals within the preferred concentrations for colouring ABP. With E142 und E171 marked ABP were traceable in food and feed using detection methods TLC (limit of detection: ≥7,5 µg E142 per kg sample), photometry and ICP-OES (limit of detection: ≥8,3 mg E171 per kg sample) at a proportion of 0,55% (TLC: E142) respectively 9% (ICP-OES: E171), whereas the named markers were not detectable in chemical and thermal extracted fats produced from marked high-fat ABP. Based on the visible and fluorescence spectrometric detectable autofluorescence of animal tissues as well as the uncharacteristic emission and absorption spectra of fluorescence pigments in processed ABP, fluorescence markers are not preferential for marking of slaughter by-products from category 3. Marking of slaughter by-products by air spraying device appeared practicable in due consideration of marker depletion and tissue-adapted marker per kg ABP. Current time of marking under laboratory conditions (5 sec. per kg ABP) must be graded as too long, regarding high transfer rates in slaughterhouses. Concerning the residue-free cleaning of stainless steel and even plastic surfaces from the marker solution, the utilisation of marked ABP for manufacturing of feed and technical products is unproblematic. Investigated pet food samples produced from marked ABP were from comparable commercial sensory product quality and showed no deviation of normal storability due to sterilisation. In conclusion, with E142 and E171 visible marked ABP from category 3 are suitable as crude materials for pet food production. The application of the combined marker solution (E142 and E171) have to be evaluated as comparative expensive (33 Euro per ton ABP), while the exclusive application of E142 as the optic conclusive and sensitive detectable marker for ABP is associated with sustainable costs from 1,70 to 3,40 Euro per ton ABP. To date, an EU-common regulatory framework for marking of ABP from category 3 could not be specified. Nevertheless the political discussion is still continued, especially in Germany.

There appears to be little doubt about the nature of the relationship between the fashion model and the young girl in contemporary Western culture. Dominant literature, emerging from medico-psychological and feminist research, situates the model as a disorderly influence, imbued with the capacity to infect and, hence, distort the healthy minds and bodies of 'suggestible' young girls. Opposing these perspectives is a smaller, more recent body of literature, emerging from post-feminist work that argues that the model-girl relationship is a delightful influence. Thus, the contemporary field of scholarship reveals an increasingly dichotomous way of thinking about fashion model influence: the model influences young girls in ways that are disorderly or delightful, never both. This thesis argues that to assume that the model-girl encounter is 'neatly' disorderly or delightful is shifty at best. It suggests that, in their rush to judge the fashion model as either pernicious or pleasurable, existing literature fails to account for the precision with which young girls know the fashion model. Using poststructuralist theory, the thesis argues that 'influence' may be more usefully thought of as a discursive effect, which may produce a range of effects for better and worse. Following Foucault (1972), fashion model influence is interrogated as a regime of truth about the model-girl encounter, constituted discursively under specific social, cultural and historical conditions. In so doing, the thesis makes different sense of fashion model influence, and questions influence as an independently-existing 'force' that bears down on vulnerable young girls. Drawing on a poststructural conceptual architecture, this thesis re-conceptualises the model-girl encounter as a pedagogical relationship focused on the (ideal) female body. It suggests that the fashion model, as an authoritative embodied pedagogue, transmits knowledge about 'ideal' feminine bodily conduct to the young girl, as attentive gazing apprentice. Fashion model influence is re-interrogated as the product of certain forms of disciplinary training (Foucault, 1977a), with young girls learning a discursive knowledge about how to discipline the body in ways that are properly feminine. Such a perspective departs from the notion that fashion model influence is necessarily disorderly or delightful, and makes possible a re-reading of influence in terms of learning outcomes. A problematic arises conceptualising the fashion model in this way. To consider the model as a 'good' teacher breaches a number of discursive rules for best pedagogical practice in postmodern times: She is not a pedagogue of the mind; she is not student-centred, facilitative, asexual, interpersonally engaged, relational, or authentic. To create a space for thinking differently about the model as a teacher, then, the thesis looks to ancient historical times and places in which female-to-female and body-to-body pedagogies were practised and understood. The first phase of the research project embedded in this thesis defamiliarises pedagogical work using historical texts from ancient Greece. It examines in particular the erotically embodied pedagogical relationships conducted between older, authoritative elite prostitutes known as hetairae, and their younger female apprentices. The discursive rules governing these pedagogical relationships are examined with a view to diagnosing the model-girl encounter in terms of these rules. These rules are then used to interrogate ethnographic data generated through observation of the model-girl encounter in situ in a modelling course, and through focus group interviews with groups of young girls. Working through notions of corporeal embodiment, self as art, desire, discipline, stillness, spectacle, the gaze and the conduct of conduct, the study interrogates the model-girl encounter as a contemporary pedagogical encounter. To avoid reaffirming more traditional binaries, the reading of data is ironic, working within and between binaries such as disorder/delight. Three ironic categories of femininity are produced out of the analysis: unnaturally natural, stompy grace and beautifully grotesque. These categories 'speak' the fragmentation, fissure, contradiction, inconsistency and absurdity that permeate the talk of young girls and model-girl pedagogy in the modelling classroom. Thus, the thesis offers up an analysis of the model-girl encounter that refuses the neatness and uni-dimensionality that characterises existing literature.

Abstract  The present work is a quantitative and qualitative analysis of pragmatic strategies for delivering critique, and types of politeness, used by undergraduate L2 students of English at different stages of peer-review discussion. The material examined consists of four corpora of authentic conversations between students, the main purpose of which was to give feedback on each other’s contributions during an English A-level course, at Mid-Sweden University. The conversations explored were carried out electronically, and represent four different online environments, or modes of computer-mediated communication (CMC). The material from the two asynchronous modes of CMC is comprised of L2 students’ written discussion board messages and spoken posts recorded using online software. The two synchronous environments under investigation are text-based and voice-based chat. Taking Brown and Levinson’s (1987) framework of politeness as a point of departure, the present study uses a combination of corpus and conversation analytical methods. The basic unit of analysis has been defined as the shortest message of peer-review critique that constitutes a thematic unit: these have been examined in terms of their content and politeness features associated with them, and analyzed in terms of the pragmatic strategy and type of politeness adopted. The types of pragmatic strategies or message organization patterns at different stages, i.e. initial versus subsequent feedback, of the peer-review discussion have also been analyzed. The results of the study show that the pragmatic strategies aimed at praise and agreement prevail in the corpus data produced by predominantly native speakers of Swedish. Even though the pragmatic strategies used for disagreement and negative evaluation are rich in propositional content, their occurrences and distribution vary across the four modes of CMC examined. These results seem to have wider implications in the context of online L2 learning activities, providing insights about the language of peer-review critique in a Swedish academic setting.   Keywords: computer-mediated communication (CMC), Conversation Analysis (CA), conversation management, discussion boards, feedback category, mode of CMC, peer-review discussion, politeness theory, pragmatic strategy, speech act of critique, text-based chat, type of politeness, voice-based chat, VoiceThread
