Trajectoires décisionnelles de parents d’un enfant ayant une condition médicale complexe

Les progrès médicaux, technologiques et scientifiques réalisés au cours des dernières décennies permettent à de nombreux enfants de survivre à la prématurité, à la maladie ou à des traumatismes physiques. Certains survivent avec des problèmes de santé chroniques qui altèrent le fonctionnement de plusieurs organes. Certains doivent composer avec des incapacités physiques ou intellectuelles légères, modérées ou sévères et sont maintenus en situation de dépendance médico technologique dans un contexte où les services d’aide et le soutien à domicile ne répondent pas aux besoins réels des enfants et de leur famille. Ces avancées dans le champ de la santé offrent des choix auparavant inexistants : sauver ou non la vie de l’enfant? Ces nouvelles possibilités imposent aux parents des décisions parfois difficiles qui engagent des valeurs, des croyances et ont d’énormes conséquences pour les acteurs (l’enfant, ses parents, sa famille, les membres de l’équipe soignante et des professionnels), les institutions et toute la société. Ces choix renvoient à des visions des choses et du monde, à différentes conceptions de la vie et de la mort. En nous intéressant à la trajectoire décisionnelle de parents d’enfant atteint d’une condition médicale complexe, nous souhaitions comprendre la façon dont les parents prennent des décisions à propos de leur enfant. Nous voulions également saisir les motifs décisionnels et leur façon d’évoluer avec le temps. La pensée complexe d’Edgar Morin constitue l’assise théorique principale de la recherche. Nous avons réalisé des entretiens semi-dirigés auprès de 25 parents dont 15 mères et 10 pères. Parmi les principaux résultats, notons la multiplicité des types et des objets de décision, l’influence multisystémique des motifs décisionnels et la présence de processus qui se développent au fil de la trajectoire. Les résultats permettent de proposer quelques repères susceptibles d’améliorer l’accompagnement des parents exposés à des décisions complexes à propos de leur enfant gravement malade.

L'enfant au cinéma : la condition tragique d'une figure traumatique

La recherche vise à élaborer la condition tragique qui émane de la figure de l'enfant au cinéma – à travers ses traumas, ses blessures, voire sa destruction et sa perte – devant laquelle le spectateur adulte éprouve un certain malaise. Nous pouvons voir au cinéma des enfants aux prises avec des conditions de vie traumatisantes, voire inhumaines. Que ce soit les enfants abandonnés ou orphelins, les enfants violés, les enfants maltraités, les enfants victimes de guerre – incluant la dualité paradoxale qu’instaure l'enfant-soldat, de Ivan (« L’enfance d’Ivan », Tarkovski, 1962) à Komona (« Rebelle », Kim Nguyen, 2012) – ou les enfants face à la mort, diverses situations peuvent contribuer à inscrire l'enfance dans le registre du tragique, par la destruction ou la perte de l'enfance. L'enfance détruite porte en elle une blessure (trauma) – qu'elle soit physique ou psychique – qui renvoie au « manque », ou à la fragilité humaine que traduit l'image de l'enfant dit « sans secours ». Quand l’enfant doit faire face à une situation tragique où il est sans défense et confronté à son propre anéantissement, sa figure devient pour nous traumatique. Nous suggérons que le tragique place l’enfant au cinéma dans un après-coup qui renvoie à un traumatisme premier fondamental, prototype de toute situation traumatique. Pour le psychanalyste Sigmund Freud, ce serait un traumatisme lié à la détresse infantile – le « Hilflosigkeit » – qui correspond à la première angoisse vécue par le nourrisson dû à son impuissance (« Inhibition, symptôme et angoisse », [1926] 1951, Paris : PUF). Dans cette lignée, certains psychanalystes (comme Otto Rank ou Jean-Marie Delassus) préciseraient que le traumatisme s'installe dès la naissance, qui marque de manière universelle le premier sentiment de perte et d'angoisse suite à l'éjection dans un monde étranger et d'abord impossible, ce qui correspond à une dislocation première (suivant le sens qu’en propose Benoit Goetz dans « La dislocation » (2002, Paris : Éditions de la Passion)). L'enfant au cinéma, qui traverse des épreuves qui nous sont difficiles à concevoir, nous regarde et pointe en nous nos propres faiblesses, et cela interagit avec nos propres traumatismes. Quelques exemples filmiques viendront soutenir la recherche, avec principalement l’analyse d’un film exemplaire, « Les tortues volent aussi » de Bahman Ghobadi (2004).

The main objectives of the present investigation were to evaluate the qualitative and quantitative distribution of natural cyanobacterial population and their ecobiological properties along the Cochin estuary and their application in aquaculture systems as a nutritional supplement due to their nutrient-rich biochemical composition and antioxidant potential. This thesis presents a detailed account of the distribution of cyanobacteria in Cochin estuary, an assessment of physico-chemical parameters and the nutrients of the study site, an evaluation of the effect of physico-chemical parameters on cyanobacterial distribution and abundance, isolation, identification and culturing of cyanobacteria, the biochemical composition an productivity of cyanobacteria, and an evaluation of the potential of the selected cyanobacteria as antioxidants against ethanol induced lipid peroxidation. The pH, salinity and nutritional requirements were optimized for low-cost production of the selected cyanobacterial strains. The present study provides an insight into the distribution, abundance, diversity and ecology of cyanobacteria of Cochin estuary. From the results, it is evident that the ecological conditions of Cochin estuary support a rich cyanobacterial growth.

Seasonal ramification in the biochemical composition of organic matter in Chalakudy river-estuary

The present study which is the first of its kind in this region is an attempt to generate adequate information on the relative abundances, the seasonal and spatial variations as well as on the source and fate of organic compounds found associated with the dissolved, particulate and sedimentary compartments of Chalakudy river system. The study aimed at investigating variations, the relative proportion of dissolved, particulate and sedimentary fractions of these materials as well as the pollution extent so as to be able to comment on the present condition of this river-estuarine system. This thesis focuses attention on the role of biogeoorganics in modifying the ecological and environmental condition of the dissolved, particuIate and sediment compartments with their minute variability subjected to various physical, chemical and biogeochemical processes. A scheme of study encompassing all these objectives provides the frame work for the present investigation.

Ecological characteristics of prawn culture fields in the Cochin area

Prawn culture by traditional method forms an important occupation for the people in these areas, especially in the Vypeen island. Though short term studies have been made on various aspects of prawn culture field and its ecology, a study of detailed nature covering perennial, seasonal, fields and canals between coconut plantation is lacking from these areas. This study will also enable to assess the relative productivity of different systems during different seasons and the influence of the environment on the production potentials. Therefore the present study is taken upto throw more light on the ecological characteristics of these fields with special emphasis on its primary, secondary and tertiary production. The present area of investigation includes the prawn culture fields adjacent to Cochin backwater. The Cochin backwater (O9° 58'N 76° 28'E) is a shallow semi-enclosed body of water of tropical estuary. A narrow gut, about 450 M wide forms its main connection with the Arabian sea and this region is subjected to regular tidal influenceertiary production.

Distribution and bioactive potential of soil actinomycetes from different ecological habitats

Emergence of drug resistance among pathogenic bacteria to currently available antibiotics has intensified the search for novel bioactive compounds from unexplored habitats. In the present study actinomycetes were isolated from two relatively unexplored and widely differing habitats such as mountain and wetlands and their ability to produce antibacterial substances were analyzed. Pure cultures of actinomycetes were identified by morphological and biochemical tests. Various genera of actinomycetes encountered included Nocardia, Pseudonocardia, Streptomyces, Nocardiopsis, Streptosporangium, Micromonospora, Rhodococcus, Actinosynnema, Nocardiodes, Kitasatosporia, Gordona, Intrasporangium and Streptoalloteichus. The frequency of occurrence of each genus was found to vary with sample. About 47% of wetland isolates and 33% of mountain isolates were identified as various species of Nocardia. The isolated strains differed among themselves in their ability to decompose proteins and amino acids and also in enzyme production potential. Antibiotic activities of these actinomycetes were evaluated against 12 test pathogenic bacteria by well diffusion method using agar wells in glycerol-yeast extract agar. About 95% of actinomycete isolates from wetland ecosystem and 75% of highland isolates suppressed in different degrees the growth of test pathogens. Relatively high antibacterial activity among these isolates underlined their potential as a source of novel antibiotics.

Length-weight relationship, relative condition factor (Kn) and morphometry of Arius subrostratus (Valenciennes, 1840) from a coastal wetland in Kerala

The length – weight relationship and relative condition factor of the shovel nose catfish, Arius subrostratus (Valenciennes, 1840) from Champakkara backwater were studied by examination of 392 specimens collected during June to September 2008. These fishes ranged from 6 to 29 cm in total length and 5.6 to 218 g in weight. The relation between the total length and weight of Arius subrostratus is described as Log W = -1.530+2.6224 log L for males, Log W = - 2.131 + 3.0914 log L for females and Log W = - 1.742 + 2.8067 log L for sexes combined. The mean relative condition factor (Kn) values ranged from 0.75 to 1.07 for males, 0.944 to 1.407 for females and 0.96 to 1.196 for combined sexes. The length-weight relationship and relative condition factor showed that the well-being of A. subrostratus is good. The morphometric measurements of various body parts and meristic counts were recorded. The morphometric measurements were found to be non-linear and there is no significant difference observed between the two sexes. From the present investigation, the fin formula can be written as D: I, 7; P: I, 12; A: 17 – 20; C: 26 – 32. There is no change in meristic counts with the increase in body length.

Sustainable Solid Waste Management Solutions To Kochi City, India, Through The Environmental Management Tool Ecological Footprint Analysis

Solid waste management nowadays is an important environmental issue in country like India. Statistics show that there has been substantial increase in the solid waste generation especially in the urban areas. This trend can be ascribed to rapid population growth, changing lifestyles, food habits, and change in living standards, lack of financial resources, institutional weaknesses, improper choice of technology and public apathy towards municipal solid waste. Waste is directly related to the consumption of resources and dumping to the land. Ecological footprint analysis – an impact assessment environment management tool makes a relationship between two factors- the amount of land required to dispose per capita generated waste. Ecological footprint analysis is a quantitative tool that represents the ecological load imposed on the earth by humans in spatial terms. By quantifying the ecological footprint we can formulate strategies to reduce the footprint and there by having a sustainable living. In this paper, an attempt is made to explore the tool Ecological Footprint Analysis with special emphasis to waste generation. The paper also discusses and analyses the waste footprint of Kochi city,India. An attempt is also made to suggest strategies to reduce the waste footprint thereby making the city sustainable, greener and cleaner
