Constructions et représentation de la classe ouvrière du Nord du Québec à Fermont

À l'ère de la mondialisation, où la matrice capitaliste continue de dominer, la classification dans les groupes se définit encore en termes de classes, de genres et d'ethnicité. Les transformations causées par la mondialisation actuelle entraînent de nouveaux modes de production, qui à leur tour transforment les modes de définition et de régulation des populations. Le projet d'exploitation du Nord du Québec est un phénomène relativement récent; or, le processus de construction d'une classe sociale n'est pas un phénomène nouveau. La formation des classes sociales étant toujours en évolution, il semble aujourd'hui pertinent de réexaminer les facteurs économiques, sociologiques et historiques des caractéristiques théoriques nécessaires à la construction et à la représentation d'une classe sociale dont l'existence est liée à l'exploitation accrue des richesses naturelles, la classe ouvrière du Nord du Québec.

 À Fermont, dans le Nord du Québec, les compagnies minières emploient depuis 2011 une grande quantité de travailleurs québécois provenant de l'extérieur de la région, des travailleurs permanents non- résidents. Ainsi, la structure sociale construite sur la force de travailleurs locaux est aux prises avec de nouvelles dynamiques de mobilité sociale géographique. Au travail, les femmes et les autochtones sont aussi affectés par les relations des systèmes de pouvoir de la vie quotidienne, car les emplois de l'industrie minière et du domaine de la construction sont socialement et historiquement fondés sur des capitaux sociaux et culturels (blanc et homme). La classe ouvrière du Nord du Québec est redéfinit par son rapport à la migration géographique des travailleurs permanents non- résidents, par ses relations avec les minorités de genre et les minorités autochtones, relations qui engendrent une organisation sociale complexe et hétérogène.

Novel Hetrocyclic Constructions Mediated by Nucleophilic Carbenes and Related Chemistry

The thesis entitled novel heterocyclic constructions mediated by nucleophilic carbenes and related chemistry, embodies the results of the investigations carried out to explore the reactivity patterns of the 1:1 zwitterions, generated in situ from various nucleophilic carbenes and DiMethyl AcetyleneDicarboxylate(DMAD) towards aldehydes and ketones. The traditional synthesis of complex organic molecules employs stepwise formation of bonds and involves multiple steps. Besides the sequential synthesis, in several instances, the desired product can also be obtained in one pot reactions of three or more starting compounds. Such reactions in which more than two starting materials react to form a product in such a way that the majority of the atoms of the starting materials can be found in the products are called multicomponent reactions(MCRs). The results of our investigations on the application of N-heterocyclic carbenes in multicomponent reaction with DMAD and aromatic aldehydes leading to the one pot synthesis of 2-oxy-maleate and furanone derivatives. It is interesting to note that dihydrofuran and lactone motifs are present in a number of biologically active natural products and other heterocyclic compounds. It is conceivable that the novel multicomponent reactions described herein will find application in the synthesis of a variety of heterocyclic compounds, and in natural product synthesis.

Novel Strategies for Heterocyclic Constructions via 1, 4-Dipolar Intermediates

In the thesis entitled " Novel Strategies for Heterocyclic Constructions via 1 ,4-Dipolar Intermediates"Synthesis of a complex organic molecules essentially involves the formation of carbon-carbon and carbon-heteroatom bonds. Various synthetic methods are available for these processes involving ionic, pericyclic and radical reactions. Among the pericyclic reactions, dipolar cycloaddition reactions, introduced by Huisgen, have emerged as a very powerful tool for heterocyclic construction. Heterocyclic compounds remain an important class of organic molecules due to their natural abundance and remarkable biological activity, thus constituting an intergral part of pharmaceutical industry. In this respect, developing newer synthetic methodology for heterocyclic construction has been an area of immense interest. In recent years, 1,3-dipolar cycloaddition reactions proved to be efficient routes to a wide variety of five membered heterocycles, as attested by their application in the total synthesis of various complex organic molecules. However, the potential application of similar 1,4- dipolar cycloaddition reactions for the construction of six memebered heterocycles remained underexploited. In this context, a systematic investigation of the reactivity of 1,4-dipoles generated from nitrogen heterocycles (pyridine and its analogues) and dimethyl acetylenedicarboxy!ate (DMAD) towards various dipolarophiles has been carried out and the results are embodied.

The intelligibility of cleft palate speech with and without dental prosthesis

This paper discusses a study to investigate the possibility of quantifying and analyzing the speech of cleft palate subjects.

An analysis of vocabulary and language constructions of six series of primary readers from the standpoint of teaching the deaf

This paper discusses a study to determnine the vocabulary and language construction of primary readers and suitability for use in teaching of hearing impaired children.

Are clefts contagious in conversation?

It is well known that conversationalists often imitate their own body language as a sign of closeness and empathy. This study shows that in spontaneous, unplanned conversation, speakers go as far as emulating each other's grammar. The use of a family of focusing constructions (namely, the cleft), such as it was my mother who rang the other day, or what I meant to say was that he should go Thursday, was investigated in a corpus of conversation excerpts in New Zealand English. Findings show that clefting is contagious. In other words, if one speaker uses a cleft, others will be likely to do so too.

The effect of cleft lip and palate, and the timing of lip repair on mother-infant interactions and infant development

Background: Children with cleft lip and palate are at risk for psychological problems. Difficulties in mother-child interactions may be relevant, and could be affected by the timing of lip repair. Method: We assessed cognitive development, behaviour problems, and attachment in 94 infants with cleft lip (with and without cleft palate) and 96 non-affected control infants at 18 months; mother-infant interactions were assessed at two, six and 12 months. Index infants received either 'early', neonatal, lip repair, or 'late' repair (3-4 months). Results: Index infants did not differ from controls on measures of behaviour problems or attachment, regardless of timing of lip repair; however, infants having late lip repair performed worse on the Bayley Scales of Mental Development; the cognitive development of early repair infants was not impaired. Difficulties in early mother-infant interactions mediated the effects of late lip repair on infant cognitive outcome. Conclusions: Early interaction difficulties between mothers and infants having late repair of cleft lip are associated with poor cognitive functioning at 18 months. Interventions to facilitate mother-infant interactions prior to surgical lip repair should be explored.

Recalled relationships with parents and perceptions of professional support in mothers of infants treated for cleft lip

This study examined whether individual differences in perception of the quality of professional support available at a time of stress may be associated with security of attachment. We developed a new measure of parents' perceptions of emotional and practical support provided by a wide range of professionals involved in the treatment of infants with cleft lip. it showed good internal reliability and stability over 4 months. Mothers of 102 infants with cleft lip, with or without cleft palate, completed the measure at 2 and 6 months, together with the Parental Bonding Instrument and the General Health Questionnaire. Mean scores reflecting how much they could trust or talk frankly, or share their worst fears, with professionals, and the extent to which they saw them as a source of useful information or practical help, were lower among mothers with recollections of low maternal care in childhood, or high control. This was the case at 2 and 6 months, and there were some indications of an increasing contribution of low maternal care from 2 to 6 months. The associations were not explained by current depression. Further research is needed to clarify the role of attachment processes in parents' responses to serious medical conditions in their children, and into the implications for the way professionals in paediatric services provide support.

Does repairing a cleft lip neonatally have any effect on the longer-term attractiveness of the repair?

Objective: To determine whether attractiveness and success of surgical outcome differ according to the timing of cleft lip repair. Design: Three experiments were conducted: (1) surgeons rated postoperative medical photographs of infants having either neonatal or 3-month lip repair; (2) lay panelists rated the same photographs; (3) lay panelists rated dynamic video displays of the infants made at 12 months. Normal comparison infants were also rated. The order of stimuli was randomized, and panelists were blind to timing of lip repair and the purposes of the study. Setting: Four U.K. regional centers for cleft lip and palate. Participants: Infants with isolated clefts of the lip, with and without palate. Intervention: Early lip repair was conducted at median age 4 days (inter-quartile range [IQR] = 4), and late repair at 104 days (IQR = 57). Main Outcome Measures: Ratings of surgical outcome (Experiment 1 only) and attractiveness (all experiments) on 5-point Likert scales. Results: In Experiment 1 success of surgical outcome was comparable for early and late repair groups (difference = -0.08; 95% confidence interval [CI] = -0.43 to 0.28; p = .66). In all three experiments, attractiveness ratings were comparable for the two groups. Differences were, respectively, 0.10 (95% CI = -2.3 to 0.44, p = .54); -0.11 (95% CI = -0.42 to -0.19, p = .54); and 0.08 (95% CI = -0.11 to 0.28, p =.41). Normal infants were rated more attractive than index infants (difference = 0.38; 95% CI = 0.24 to 0.52; p < .001). Conclusion: Neonatal repair for cleft of the lip confers no advantage over repair at 3 months in terms of perceived infant attractiveness or success of surgical outcome.

The effect of cleft lip on socio-emotional functioning in school-aged children

Background: Children with cleft lip are known to be at raised risk for socio-emotional difficulties, but the nature of these problems and their causes are incompletely understood; longitudinal studies are required that include comprehensive assessment of child functioning, and consideration of developmental mechanisms. Method: Children with cleft lip (with and without cleft palate) (N = 93) and controls (N = 77), previously studied through infancy, were followed up at 7 years, and their socio-emotional functioning assessed using teacher and maternal reports, observations of social interactions, and child social representations (doll play). Direct and moderating effects of infant attachment and current parenting were investigated, as was the role of child communication difficulties and attractiveness. Results: Children with clefts had raised rates of teacher-reported social problems, and anxious and withdrawn-depressed behaviour; direct observations and child representations also revealed difficulties in social relationships. Child communication problems largely accounted for these effects, especially in children with cleft palate as well as cleft lip. Insecure attachment contributed to risk in both index and control groups, and a poorer current parenting environment exacerbated the difficulties of those with clefts. Conclusions: Children with clefts are at raised risk for socio-emotional difficulties in the school years; clinical interventions should focus on communication problems and supporting parenting; specific interventions around the transition to school may be required. More generally, the findings reflect the importance of communication skills for children’s peer relations.

Grammatical collocations and verb-particle constructions in Brussels French: a corpus-linguistic approach to transfer

In this study the focus is on transfer in Brussels French, the variety of French spoken in Brussels. The methodology proposed in Jarvis (2000) and Jarvis and Pavlenko (2009) is followed to provide proof for the fact that grammatical collocations such as chercher après "to look for" are the result of contact with the source language, Brussels Dutch.

The effect of cleft lip on cognitive development in school-aged children: a paradigm for examining sensitive period effects

Background:  Our previous investigation showed that infants with cleft lip who had undergone late (three-month) surgical repair (but not those with early, neonatal, repair) had significantly poorer cognitive development at 18 months than a group of unaffected control children. These differences were mediated by the quality of early mother–infant interactions. The present study examined whether this pattern persisted into later childhood. Method:  At 7 years, 93 index (44 early, and 49 late repair) and 77 control children were followed up and their cognitive development assessed (IQ, language and school achievements). Results:  Index children (particularly those with late lip repair) scored significantly lower than controls on tests of cognitive development. Group differences in Verbal IQ were mediated by 2 months’ maternal sensitivity; this was associated with 7-year Verbal IQ, even after controlling for later mother–child interactions. Conclusions:  Social interactions in the first few months may be of especial importance for child cognitive development. Interventions for infants with cleft lip should be directed at fostering the best possible parental care in infancy.
