It is often postulated that an increased hip to shoulder differential angle (`X-Factor') during the early downswing better utilises the stretch-shorten cycle and improves golf performance. The current study aims to examine the potential relationship between the X-Factor and performance during the tee-shot. Seven golfers with handicaps between 0 and 10 strokes comprised the low-handicap group, whilst the high-handicap group consisted of eight golfers with handicaps between 11 and 20 strokes. The golfers performed 20 drives and three-dimensional kinematic data were used to quantify hip and shoulder rotation and the subsequent X-Factor. Compared with the low-handicap group, the high-handicap golfers tended to demonstrate greater hip rotation at the top of the backswing and recorded reduced maximum X-Factor values. The inconsistencies evident in the literature may suggest that a universal method of measuring rotational angles during the golf swing would be beneficial for future studies, particularly when considering potential injury.

Telecommunications is a key component in any country's economic infrastructure, requiring a vast amount of capital injection and ongoing technical support and innovation. Many developing countries experience handicaps in accessing capital and sustaining the required technical capability in their industralisation process. Therefore, attracting both capital investments and expertise by attuning the developing country's economic policies and legal environment to meet investors' expectations is a priority. Privatisation has been seen as a triumph by international institutions such as the World Bank, and a major requirement for developing economies to industrialise. However from a regulatory perspective, this process is far from straightforward. Implementing economic policies requires a number of regulations and regulatory instruments to be in place. Apart from the need for an independent regulator, regulatory outcomes are often dependent on the willingness of various stakeholders to comply with the course of actions undertaken by authorities. This article examines the factors steering the processes and changes in the telecommunication reforms of Indonesia and China.

Life of children exposed to alcohol or drugs in utero This study focused on the growth environment, physical development and socio-emotional development of children, aged 16 and under, who had been exposed to alcohol (n=78) or drugs (n=15) in utero. The aim of the study was to obtain a comprehensive picture of the living conditions of these children and to examine the role of the growth environment in their development. The study was carried out using questionnaires, written life stories and interviews. Attachment theory was used as a background theory in the study. Over half of the children exposed to alcohol were diagnosed with foetal alcohol syndrome (FAS), one quarter was diagnosed with foetal alcohol effects (FAE), and one fifth had no diagnosis. Most of the children exposed to drugs had been exposed to either amphetamines or cannabis, and a smaller number to heroin. Some of the children exposed to alcohol were mentally handicapped or intellectually impaired. The children exposed to drugs did not exhibit any serious learning difficulties but a considerable number of them had socio-emotional development problems. Language and speech problems and attention, concentration and social interaction problems were typical among both the children exposed to alcohol and those exposed to drugs. Only one child had been placed into long-term foster care in a family immediately after leaving the maternity hospital. In biological families there had been neglect, violence, mental health problems, crime and unemployment, and many parents were already dead. Two of the children had been sexually abused and four were suspected of having been abused. From the point of view of the children's development, the three most critical issues were 1) the range of illnesses and handicaps that had impaired their functional capacity as a result of their prenatal exposure to alcohol, 2) child's age at the time of placement on a long-term basis, and 3) the number of their traumatic experiences. The relationship with their biological parents after placement also played a role. Children with symptoms were found in all diagnosis categories and types of exposure. Children with the smallest number of symptoms were found among those who had never lived with their biological parents. Almost all children were exhibiting strong symptoms at the time of placement in foster care. In most cases, they were behaving in a disorderly manner towards others, but some children were withdrawn. The most conspicuous feature among those with the most severe symptoms was their disorganized behaviour. Placement in a foster family enhanced the children's development, but did not solve the problems. The foster parents who brought these children up did not receive as much therapy for the children and support for the upbringing as they appear to have needed. In Finland, transfer to long-term custody is based on strict criteria. The rights of children prescribed in the child protection law are not fulfilled in practice. Key words: FASD, FAS, FAE, alcohol exposure, drugs exposure, illegal drugs, early interaction, child development, attachment

This bulletin has been written primarily to serve as a handbook to the Indo-Pacific Fisheries Council at its sessions in Colombo during December 1958. It presents an outline of the fishing industry as found in Ceylon today, in non-technical language so that it may also be understood by laymen. The large gaps in our knowledge are brought out in the section on "resources"; the section on "administration" gives an indication of progress made towards solving the problems of the industry, while sections on "fishing methods" and "utilization of catch" will help us to appreciate the handicaps and difficulties of those concerned with the industry. The Government Administration of the fisheries of Ceylon is being assisted to a considerable extent by the generous gifts of machinery and equipment as well as the loan of skilled technical personnel made by other countries through the FAO and the Colombo Plan. The progress made so far has helped to place the industry in a favorable position for further improvements.

Soft-tissue and bone necrosis, although rare in childhood, occasionally occur in the course of infectious diseases, either viral or bacterial, and seem to be the result of hypoperfusion on a background of disseminated intravascular coagulation. Treatment consists in correction of septic shock and control of necrosis. Necrosis, once started, shows extraordinarily rapid evolution, leading to soft-tissue and bone destruction and resulting in anatomic, functional, psychological, and social handicaps. Ten mutilated children were treated from January 1986 to January 1999 in Hospital de Dona Estefaˆ nia, Lisbon, Portugal. One was recovering from hemolytic-uremic syndrome with a severe combined immunodeficiency, another malnourished, anemic child had malaria, and three had chicken pox (in one case complicated by meningococcal septicemia). There were three cases of meningococcal and two of pyocyanic septicemia (one in a burned child and one in a patient with infectious mononucleosis). The lower limbs (knee,leg, foot) were involved in five cases, the face (ear, nose, lip) in four, the perineum in three, the pelvis (inguinal region, iliac crest) in two, the axilla in one, and the upper limb (radius, hand) in two. Primary prevention is based on early recognition of risk factors and timely correction. Secondary prevention consists of immediate etiologic and thrombolytic treatment to restrict the area of necrosis. Tertiary prevention relies on adequate rehabilitation with physiotherapy and secondary operations to obtain the best possible functional and esthetic result.

Abstract : Auditory spatial functions are of crucial importance in everyday life. Determining the origin of sound sources in space plays a key role in a variety of tasks including orientation of attention, disentangling of complex acoustic patterns reaching our ears in noisy environments. Following brain damage, auditory spatial processing can be disrupted, resulting in severe handicaps. Complaints of patients with sound localization deficits include the inability to locate their crying child or being over-loaded by sounds in crowded public places. Yet, the brain bears a large capacity for reorganization following damage and/or learning. This phenomenon is referred as plasticity and is believed to underlie post-lesional functional recovery as well as learning-induced improvement. The aim of this thesis was to investigate the organization and plasticity of different aspects of auditory spatial functions. Overall, we report the outcomes of three studies: In the study entitled "Learning-induced plasticity in auditory spatial representations" (Spierer et al., 2007b), we focused on the neurophysiological and behavioral changes induced by auditory spatial training in healthy subjects. We found that relatively brief auditory spatial discrimination training improves performance and modifies the cortical representation of the trained sound locations, suggesting that cortical auditory representations of space are dynamic and subject to rapid reorganization. In the same study, we tested the generalization and persistence of training effects over time, as these are two determining factors in the development of neurorehabilitative intervention. In "The path to success in auditory spatial discrimination" (Spierer et al., 2007c), we investigated the neurophysiological correlates of successful spatial discrimination and contribute to the modeling of the anatomo-functional organization of auditory spatial processing in healthy subjects. We showed that discrimination accuracy depends on superior temporal plane (STP) activity in response to the first sound of a pair of stimuli. Our data support a model wherein refinement of spatial representations occurs within the STP and that interactions with parietal structures allow for transformations into coordinate frames that are required for higher-order computations including absolute localization of sound sources. In "Extinction of auditory stimuli in hemineglect: space versus ear" (Spierer et al., 2007a), we investigated auditory attentional deficits in brain-damaged patients. This work provides insight into the auditory neglect syndrome and its relation with neglect symptoms within the visual modality. Apart from contributing to a basic understanding of the cortical mechanisms underlying auditory spatial functions, the outcomes of the studies also contribute to develop neurorehabilitation strategies, which are currently being tested in clinical populations.

Les syndromes de déficiences cérébrales en créatine (CCDS) sont dus à des mutations dans les gènes GATM et G AMT (codant pour les enzymes AGAT et G AMT de la voie de synthèse de créatine) ainsi que SLC6A8 (transporteur de créatine), et génèrent une absence ou une très forte baisse de créatine (Cr) dans le cerveau, mesurée par spectroscopic de résonance magnétique. Les patients CCDS développent des handicaps neurologiques sévères. Les patients AGAT et GAMT peuvent être traités avec des doses importantes de Cr, mais gardent dans la plupart des cas des séquelles neurologiques irréversibles. Aucun traitement efficace n'existe à ce jour pour la déficience en SLC6A8. Bien que de nombreux modèles aient été développés pour comprendre la Cr cérébrale en conditions physiologiques, les pathomécanismes des CCDS ne sont pas encore compris. Des souris transgéniques pour les gènes Gatm, Gamt et Slc6a8 ont été générées, mais elles ne miment que partiellement la pathologie humaine. Parmi les CCDS, la déficience en GAMT est la plus sévère, en raison de l'accumulation cérébrale de l'intermédiaire guanidinoacétate (GAA). Alors que la toxicité cérébrale du GAA a été étudiée par exposition directe au GAA d'animaux adultes sains, les mécanismes de la toxicité du GAA en condition de déficience en GAMT dans le cerveau en développement sont encore inconnus. Le but de ce projet était donc de développer un modèle de déficience en GAMT dans des cultures 3D primaires de cellules nerveuses de rat en agrégats par knock-down du gène GAMT, en utilisant un virus adéno-associé (AAV) induisant le mécanisme d'interférence à l'ARN (RNAi). Le virus scAAV2, à la multiplicité d'infection de 1000, s'est révélé le plus efficace pour transduire tous les types de cellules nerveuses des cultures (neurones, astrocytes, oligodendrocytes), et générer un knock-down maximal de la protéine GAMT de 85% (jour in vitro 18). Cette déficience partielle en GAMT s'est révélée insuffisante pour générer une déficience en Cr, mais a causé l'accumulation attendue de GAA, à des doses comparables aux niveaux observés dans le LCR des patients GAMT. Le GAA a induit une croissance axonale anarchique accompagnée d'une baisse de l'apoptose naturelle, suivis par une induction tardive de mort cellulaire non-apoptotique. Le co-traitement par la Cr a prévenu tous les effets toxiques du GAA. Ce travail montre que l'accumulation de GAA en absence de déficience en Cr est suffisante pour affecter le développement du tissu nerveux, et suggère que des formes de déficiences en GAMT supplémentaires, ne présentant pas de déficiences en Cr, pourraient être découvertes par mesure du GAA, en particulier à travers les programmes récemment proposés de dépistage néonatal de la déficience en GAMT. -- Cerebral creatine deficiency syndromes (CCDS) are caused by mutations in the genes GATM and GAMT (respectively coding for the two enzymes of the creatine synthetic pathway, AGAT and GAMT) as well as SLC6A8 (creatine transporter), and lead to the absence or very strong decrease of creatine (Cr) in the brain when measured by magnetic resonance spectroscopy. Affected patients show severe neurological impairments. While AGAT and GAMT deficient patients can be treated with high dosages of Cr, most remain with irreversible brain sequelae. No treatment has been successful so far for SLC6A8 deficiency. While many models have helped understanding the cerebral Cr pathways in physiological conditions, the pathomechanisms underlying CCDS are yet to be elucidated. Transgenic mice carrying mutations in the Gatm, Gamt and Slc6a8 genes have been developed, but only partially mimic the human pathology. Among CCDS, GAMT deficiency is the most severe, due to the CNS accumulation of the guanidinoacetate (GAA) intermediate. While brain toxicity of GAA has been explored through direct GAA exposure of adult healthy animals, the mechanisms underlying GAA toxicity in GAMT deficiency conditions on the developing CNS are yet unknown. The aim of this project was thus to develop and characterize a GAMT deficiency model in developing brain cells by gene knockdown, by adeno-associated virus (AAV)-driven RNA interference (RNAi) in rat 3D organotypic primary brain cell cultures in aggregates. scAAV2 with a multiplicity of infection of 1000 was shown as the most efficient serotype, was able to transduce all brain cell types (neurons, astrocytes, oligodendrocytes) and to induce a maximal GAMT protein knockdown of 85% (day in vitro 18). Metabolite analysis showed that partial GAMT knockdown was insufficient to induce Cr deficiency but generated the awaited GAA accumulation at concentrations comparable to the levels observed in cerebrospinal fluid of GAMT-deficient patients. Accumulated GAA induced axonal hypersprouting paralleled with inhibition of natural apoptosis, followed by a later induction in non-apoptotic cell death. Cr supplementation led to the prevention of all GAA-induced toxic effects. This work shows that GAA accumulation without Cr deficiency is sufficient to affect CNS development, and suggests that additional partial GAMT deficiencies, which may not show the classical brain Cr deficiency, may be discovered through GAA measurement including by recently proposed neonatal screening programs for GAMT deficiency.

Le désir d’avoir un enfant est universel. Les récentes avancées en génétique ont donné naissance au test génétique prénatal. Le diagnostic prénatal classique ou préimplantatoire permet de déceler des anomalies au stade foetal ou préembryonnaire. Ce type de test génétique est offert aux parents « à risque » de donner naissance à un enfant atteint d’une maladie génétique grave cependant la demande est grandissante auprès des autres couples. Il y a diverses pressions (directes ou indirectes) qui poussent les parents à recourir à ce type d’examen. La pression de la société et même l’État pousse les parents à se soumettre au test qui est une source importante de stress. La pression établit une normativité et renforce les préjugés envers les handicapés et influence la prise de décision des parents face au résultat. L’équipe médicale exerce une influence et le sentiment de culpabilité de mettre un enfant malade au monde hante les parents. Bien que les progrès de la génétique ont plusieurs avantages comme de permettre à des couples qui sans le dépistage prénatal n’auraient pas eu d’enfant la liberté de procréer doit rester au premier plan.

Depuis l’adoption de la politique de l’adaptation scolaire en 1999, le ministère de l’Éducation, du Loisir et du Sport a mis en place un plan d’action pour permettre l’intégration des élèves handicapés ou en difficulté d’adaptation ou d’apprentissage. L’intégration des élèves handicapés a fait l’objet de plusieurs études ; toutefois, peu d’entre elles se sont intéressées à l’intégration d’élèves présentant une déficience auditive et utilisant le langage parlé complété. Le but de cette étude est de mettre en lumière les perceptions d’élèves présentant une déficience auditive quant à l’utilisation du langage parlé complété en contexte d’intégration scolaire. Les concepts exploités dans ce mémoire sont relatifs à la surdité, aux élèves présentant une déficience auditive, aux modes de communication utilisés auprès de ces élèves, et plus particulièrement le langage parlé complété, de même qu’au contexte d’intégration scolaire québécois. Cette recherche est de type exploratoire et la méthode utilisée est qualitative. Cinq étudiants présentant une déficience auditive et âgés entre 12 et 17 ans ont participé à une entrevue semi-dirigée. Les résultats de ces entretiens montrent que ces élèves ont des perceptions positives et négatives face à l’utilisation du langage parlé complété en contexte d’intégration. Quoique de façon générale cela n’entrave pas leur intégration scolaire, les perceptions négatives se rapportent davantage à l’intégration sociale qu’à l’intégration scolaire.

Cette recherche porte sur la situation des élèves dysphasiques au Québec. En effet, l’identification de leur trouble, l’accessibilité à des services adaptés et la scolarisation de ces élèves a connu, à travers les années, quelques problèmes. Actuellement, 66,40% des élèves dysphasiques sévères au Québec ne sont pas scolarisés en classe ordinaire (MELS, 2008b). Une partie d’entre eux se retrouve dans des classes de langage aussi appelées classes de communication. Ce milieu de scolarisation fait partie du niveau 5 du système en cascade proposé dans le rapport COPEX (MEQ, 1976). Ce type de service a été mis en place afin de répondre, entre autres, aux besoins particuliers de la population d’élèves dysphasiques sévères. Par contre, leur efficacité par rapport à la réussite éducative de ces élèves n’est toujours pas évaluée. La recension des écrits a permis l’approfondissement des éléments-clés de la recherche, soit la dysphasie, la classe de langage et l’efficacité. Cette même recension a permis à la chercheuse de se positionner par rapport au cadre méthodologique utilisé. Ainsi, cette étude qualitative de type exploratoire vise à aller chercher sur le terrain des informations concernant l’efficacité des classes de langage. Celles-ci ont été collectées en utilisant principalement l’entretien individuel, le questionnaire ayant plutôt servi à collecter des informations factuelles sur les participants. Les personnes questionnées, qui sont au nombre de neuf, sont les principaux agents qui gravitent autour de l’élève dysphasique sévère fréquentant une classe de langage : les parents, les enseignants et les orthophonistes. Les résultats permettent une avancée dans la recherche pour ce qui est des effets de la classe de langage sur la réussite éducative des élèves dysphasiques sévères.
