Extradition et non-refoulement : la justice fondamentale en péril? Analyse du cas Németh c. Canada (Justice)

Dans Németh c. Canada (Justice) (2010), la Cour suprême vient à la conclusion qu’il est possible, pour le ministre de la Justice, d’autoriser l’extradition d’un réfugié dans la mesure où cette dernière n’est pas injuste ou tyrannique, et qu’elle ne vise pas à punir la personne pour des motifs de persécution. Le juge Cromwell précise qu’il n’est pas nécessaire de révoquer le statut de réfugié avant le processus d’extradition ; le ministre n’a qu’à démontrer que les clauses de cessation se trouvant dans la Loi sur l’immigration et la protection des réfugiés s’appliquent. Cela implique qu’il doit faire la preuve, selon la balance des probabilités, que les réfugiés n’ont plus de raison de craindre la persécution dans leur pays d’origine, en établissant qu’il y a un changement stable de circonstances. Toutefois, le processus actuel d’extradition n’assure pas pleinement les protections procédurales auxquelles ont droit les réfugiés, dans la mesure où la Loi sur l’extradition accorde un pouvoir discrétionnaire au ministre de décider, au cas par cas, qui devrait avoir droit à une audition orale pour étayer sa cause. Puisque la possibilité de persécution au retour reste une question empreinte de subjectivité et fait appel à la crédibilité, il est du devoir du ministre d’accorder une forme d'audition aux réfugiés afin d’offrir de solides garanties procédurales. Or, la Cour n’est pas allée jusqu’à prescrire un tel devoir. Dans ce mémoire, nous nous interrogeons sur l’étendue des protections procédurales qui devraient être accordées à un réfugié menacé d’extradition.

Le devoir syndical de représentation sous l'angle de la Charte des droits et libertés de la personne: le cas des clauses" orphelin"

En raison des présentes transformations du marché du travail, le mouvement syndical est à la recherche d’un nouvel équilibre. Dans ce contexte plutôt changeant, réorganisations et flexibilité se négocient en échange d’une protection accrue pour ceux qui demeurent en emploi. Si d’une part, ceci mène à une prolifération de nouvelles formes d’emploi atypiques et de disparités de traitement, d’autre part la constitutionnalisation du droit du travail change le rapport quant à l’universalisme syndical. Nous nous sommes alors interrogée sur les impacts que cela peut avoir sur le devoir syndical de représentation. Prenant cela en considération, nous avons voulu au cours de notre recherche faire la lumière tant sur certains impacts de la négociation de clauses de disparité de traitement dans les milieux de travail syndiqués que sur les défis contemporains du droit du travail et de l’emploi. Cette thèse propre au champ d’études que sont les relations industrielles se distingue des autres recherches dans le même domaine en se concentrant sur l’effet empirique de la mise en œuvre d’une norme, par l’étude de deux cas suggestifs. Plus précisément, notre thèse avait comme principal objectif de répondre à la question suivante : Quels sont les effets sur l’acteur (action) syndical du recours à la norme d’égalité, à la suite la négociation de clauses « orphelin »? Pour y parvenir, nous avons dû reconstituer comment les acteurs syndicaux s’étaient approprié l’espace ouvert par la constitutionnalisation du droit du travail. Nous avons utilisé une méthode qualitative, impliquant une revue de la littérature sociohistorique, théorique et juridique, une analyse de la jurisprudence existant à ce sujet et l’étude de deux cas portant sur la négociation d’une clause « orphelin » le tout représentant soixante entrevues semi-dirigées dans plusieurs casernes et palais de justice. Les connaissances acquises permettent au plan empirique une meilleure compréhension des interactions possibles entre acteurs, institutions et stratégies lors de la mise en œuvre de la norme d’égalité ainsi que des déterminants de l’action (ou de l’inaction) syndicale. Sur le plan pratique, nous espérons que notre thèse puisse guider toute personne ou tout groupe de personnes désirant mettre en œuvre des mesures égalitaires, tant pour éviter certains écueils reliés à ces actions ou réactions suscitées par la mise en œuvre du droit à l’égalité, que pour mesurer l’efficacité des actions entreprises. De surcroît, sur le plan théorique, nous croyons que de mettre à l’épreuve un modèle théorique recoupant stratégies et institutions permettra d’aborder les problèmes à la fois au niveau de l’acteur et au niveau structurel. Les résultats obtenus aident à comprendre en quoi et comment peut se construire l’action syndicale dans certains (2) cas de mise en œuvre de la norme d’égalité. Le choix de différentes stratégies ne peut pas être dissocié des différents contextes économiques, sociaux et juridiques, ni des capacités stratégiques des différents acteurs en cause. Les principales contraintes identifiées ont pu être imputées tant aux structures de l’association syndicale qu’aux différents univers normatifs mobilisés. Les sources de tensions vécues dans les milieux à l’étude ont été rattachées notamment aux perceptions d’injustice et à la méconnaissance des différentes normes juridiques. En conséquence, il faut conclure que pour les associations syndicales (sans se restreindre à celles à l’étude), la question d’iniquité pourrait avoir de graves conséquences et non seulement sur le devoir de représentation. Nous avons spécialement souligné la fragilisation de leurs assises, dans leurs deux pôles d’actions : d’acteur économique (faille dans la capacité d’action traditionnelle) et d’acteur politique (climat hostile au syndicalisme). Nous souhaitons que l’acteur syndical puisse mobiliser, à la lumière des résultats de notre recherche, des arguments concourant à repenser l’action syndicale, que nous croyons être plus pertinente que jamais. Nous croyons également que les différents acteurs du monde du travail pourraient s’approprier certaines de nos recommandations afin de favoriser une citoyenneté au travail plus inclusive.

Syntactic complexity in the comprehension of wh-questions and relative clauses in typical language development and autism

This study investigates effects of syntactic complexity operationalised in terms of movement, intervention and (NP) feature similarity in the development of A’ dependencies in 4-, 6-, and 8-year old typically developing (TD) French children and children with Autism Spectrum Disorders (ASD). Children completed an off-line comprehension task testing eight syntactic structures classified in four levels of complexity: Level 0: No Movement; Level 1: Movement without (configurational) Intervention; Level 2: Movement with Intervention from an element which is maximally different or featurally ‘disjoint’ (mismatched in both lexical NP restriction and number); Level 3: Movement with Intervention from an element similar in one feature or featurally ‘intersecting’ (matched in lexical NP restriction, mismatched in number). The results show that syntactic complexity affects TD children across the three age groups, but also indicate developmental differences between these groups. Movement affected all three groups in a similar way, but intervention effects in intersection cases were stronger in younger than older children, with NP feature similarity affecting only 4-year olds. Complexity effects created by the similarity in lexical restriction of an intervener thus appear to be overcome early in development, arguably thanks to other differences of this intervener (which was mismatched in number). Children with ASD performed less well than the TD children although they were matched on non-verbal reasoning. Overall, syntactic complexity affected their performance in a similar way as in their TD controls, but their performance correlated with non-verbal abilities rather than age, suggesting that their grammatical development does not follow the smooth relation to age that is found in TD children.

Passives without actives: evidence from verbless complement clauses in Spanish

This paper proposes a constructionist analysis à la Goldberg (1995, 2003, 2006) of passive verbless configurations in Spanish lacking a felicitous active counterpart.Under the paradigmatic – rather than syntagmatic – view of passives invoked in this paper, configurations of the type in (1) above, attested with a number of verba cogitandi et dicendi, are handled as instances of the Impersonal Subjective-Transitive construction, whose general skeletal meaning is X (NP1) attributed Y (XPCOMP) by Z (NP2) in a direct, categorical way. Moreover, the analysis proposed here also provides a satisfactory account of the distribution of grammatical subjects and the XPCOMPs, while also capturing the commonalities with “regular” passives (i.e. those with a felicitous active counterpart). In addition, Spanish passive verbless complement configurations with se dice (‘is said’) are shown to illustrate a three-point continuum consisting of (i) non-grammaticalized configurations with an active counterpart, (ii) non-grammaticalized configurations without an active counterpart, and (iii) grammaticalized configurations without an active counterpart. From a synchronic point of view, the structural and semantico-pragmatic properties exhibited by the lower-level lo que se dice XPFOCUS construction, involving a focusing/emphasizer subjunct function (e.g. verdaderamente ‘really’) as well as a reformulatory connective use (e.g. o sea ‘that is’, en otras palabras ‘in other words’) appear to point to an early process of grammaticalization, exhibiting decategorialization as well as generalization of meaning in conjunction with a prominent increase in pragmatic function and subjectification (cf. Traugott 1988, 1995a, 1995b, 2003).

Imperatives in concessive clauses: compatibility between constructions

In his pioneering paper on “Performative Subordinate Clauses,” Lakoff (1984) claimed that subordinate clauses expressing a reason or concession allow imperatives conveying statements (i.e. assertive illocutionary force). While this analysis has gone unchallenged to this day, the present paper shows that Lakoff’s analysis is inadequate, in that reason and concessive clauses show a sharp contrast in the kinds of imperative utterances they permit. Contra Lakoff, concessive clauses with although, though and except (that) do allow imperative constructions conveying directive illocutionary forces to occur, whereas by contrast those with even though tend to disallow both types of imperatives. These findings can be explained in terms of compatibility between “component” constructions constituting a complex sentence. It is argued that the compatibility between imperatives (both directive and assertive types) and concessive adverbials (excluding even though) can be attributed to the latter’s loose integration into a matrix clause required by the former. Furthermore, it is argued that the incompatibility of even though with imperatives arises primarily from the incompatibility between the tight integration of even though and the loose integration required by imperatives, together with the associated incompatibility between the non-rectifying function of even though and the rectifying conjunction favored by imperatives.

Checking the concurrence among macrobenthic organism distribution patterns at different taxonomic scales in relation to environmental factors

The interaction of both natural conditions and anthropogenic environmental impacts can lead to different soft-bottom macrobenthic distribution patterns. Soft-bottom macrobenthic community was analysed at different taxonomic scales in order to evaluate whether diverse subset of organisms respond to the variability of the environmental pressures (natural and human induced) showing or not similar distribution patterns. Therefore, this long-term survey had been focused on a heterogeneous area, where both anthropogenic and natural stress may affect the community. Three perpendicular transects to the coast were established and stations at 4, 10 and 15 m depths were sampled at each transect twice a year (summer- winter) from 2004 to 2009. Non-parametric multivariate techniques were used to analyse soft-bottom macrobenthic community distribution and its relation to the environmental factors. Similar distribution patterns between investigated taxonomic levels were detected and they were mainly related to depth.

L’évaluation du personnel enseignant non permanent au Collège de la région de l'Amiante

Alors que le volume de leur clientèle baisse, que les modes de subventions sont requestionnés, que la concurrence entre les collèges s'installe, que les employeurs et la clientèle expriment de plus en plus clairement leurs besoins, qu'une récession continue à menacer l'économie du pays, les collèges doivent assurer une meilleure formation à leurs élèves et ce au moindre coût. Chaque collège se voit donc forcé d'introduire dans sa gestion des ressources humaines les concepts d'efficacité et d'efficience et, en conséquence, d'introduire des pratiques d'évaluation et ce à la demande expresse des contribuables qui prétendent payer trop cher les services rendus par les collèges. Qui plus est, certains vérificateurs externes des collèges commencent à s'interroger sur la façon dont les collèges assument leur responsabilité en ce qui concerne l'enseignement. Compte tenu des sommes impliquées pour le personnel enseignant, ils jugent nos systèmes de contrôle déficients, sentiment largement partagé par l'ensemble de la population. Toutefois, il nous semble important de souligner, dès le départ, que l'évaluation du personnel enseignant est un sujet délicat. Tout le monde théorise sur le sujet, tout le monde en reconnaît la nécessité mais peu de collèges passent à l'action. Pourtant, il s'en fait de l'évaluation dans notre collège. Chaque année, le directeur général dépose au ministre de l'Enseignement supérieur et de la Science un rapport de nos activités; chaque année, nous présentons à la Direction générale de l'enseignement collégial nos états financiers; chaque année, tous les départements déposent à la Direction des services pédagogiques un rapport comprenant d'une part l'évaluation des activités tenues au cours de l'armée et d'autre part, la présentation des prospectives pour l'armée à venir; depuis 1985, le Collège s'est donné et a implanté une politique institutionnelle d'évaluation des apprentissages des étudiants dont le suivi est assuré annuellement par la Commission pédagogique; chaque année se fait, de façon systématique, l'évaluation du rendement des cadres du collège.

On L2 grammar and processing: the case of oblique relative clauses and the Null-Prep phenomenon

This dissertation investigates the acquisition of oblique relative clauses in L2 Spanish by English and Moroccan Arabic speakers in order to understand the role of previous linguistic knowledge and its interaction with Universal Grammar on the one hand, and the relationship between grammatical knowledge and its use in real-time, on the other hand. Three types of tasks were employed: an oral production task, an on-line self-paced grammaticality judgment task, and an on-line self-paced reading comprehension task. Results indicated that the acquisition of oblique relative clauses in Spanish is a problematic area for second language learners of intermediate proficiency in the language, regardless of their native language. In particular, this study has showed that, even when the learners’ native language shares the main properties of the L2, i.e., fronting of the obligatory preposition (Pied-Piping), there is still room for divergence, especially in production and timed grammatical intuitions. On the other hand, reaction time data have shown that L2 learners can and do converge at the level of sentence processing, showing exactly the same real-time effects for oblique relative clauses that native speakers had. Processing results demonstrated that native and non-native speakers alike are able to apply universal processing principles such as the Minimal Chain Principle (De Vincenzi, 1991) even when the L2 learners still have incomplete grammatical representations, a result that contradicts some of the predictions of the Shallow Structure Hypothesis (Clahsen & Felser, 2006). Results further suggest that the L2 processing and comprehension domains may be able to access some type of information that it is not yet available to other grammatical modules, probably because transfer of certain L1 properties occurs asymmetrically across linguistic domains. In addition, this study also explored the Null-Prep phenomenon in L2 Spanish, and proposed that Null-Prep is an interlanguage stage, fully available and accounted within UG, which intermediate L2 as well as first language learners go through in the development of pied-piping oblique relative clauses. It is hypothesized that this intermediate stage is the result of optionality of the obligatory preposition in the derivation, when it is not crucial for the meaning of the sentence, and when the DP is going to be in an A-bar position, so it can get default case. This optionality can be predicted by the Bottleneck Hypothesis (Slabakova, 2009c) if we consider that these prepositions are some sort of functional morphology. This study contributes to the field of SLA and L2 processing in various ways. First, it demonstrates that the grammatical representations may be dissociated from grammatical processing in the sense that L2 learners, unlike native speakers, can present unexpected asymmetries such as a convergent processing but divergent grammatical intuitions or production. This conclusion is only possible under the assumption of a modular language system. Finally, it contributes to the general debate of generative SLA since in argues for a fully UG-constrained interlanguage grammar.

Non-comital women of twelfth-century England: a charter based analysis

This thesis sets out to explore the place and agency of non-comital women in twelfth-century Anglo-Norman England. Until now, broad generalisations have been applied to all aristocratic women based on a long established scholarship on royal and comital women. Non-comital women have been overlooked, mainly because of an assumed lack of suitable sources from this time period. The first aim of this thesis is to demonstrate that there is a sufficient corpus of charters for a study of this social group of women. It is based on a database created from 5545 charters, of which 3046 were issued by non-comital women and men, taken from three case study counties, Oxfordshire, Suffolk and Yorkshire, and is also supported by other government records. This thesis demonstrates that non-comital women had significant social and economic agency in their own person. By means of a detailed analysis of charters and their clauses this thesis argues that scholarship on non-comital women must rethink the framework applied to the study of non-comital women to address the lifecycle as one of continuities and as active agents in a wider public society. Non-comital women’s agency and identity was not only based on land or in widowhood, which has been the one period in their life cycles where scholars have recognised some level of autonomy, and women had agency in all stages of their life cycle. Women’s agency and identity were drawn from and part of a wider framework that included their families, their kin, and broader local political, religious, and social networks. Natal families continued to be important sources of agency and identity to women long after they had married. Part A of the thesis applies modern charter diplomatic analysis methods to the corpus of charters to bring out and explore women’s presence therein. Part B contextualises these findings and explores women’s agency in their families, landholding, the gift-economy, and the wider religious and social networks of which they were a part.

The subjunctive mood in Late Middle English adverbial clauses: the interaction of form and function

This thesis focuses on the history of the inflexional subjunctive and its functional substitutes in Late Middle English. To explore why and how the inflexional subjunctive declined in the history of English language, I analysed 2653 examples of three adverbial clauses introduced by if (1882 examples), though (305 examples) and lest (466 examples). Using a corpus-based approach, this thesis argues that linguistic change in subjunctive constructions did not happen suddenly but rather gradually, and the way it changed was varied , and that different constructions changed at different speeds in different environments. It is well known that the inflexional subjunctive declined in the history of English, mainly because of inflexional loss. Strangely however this topic has been comparatively neglected in the scholarly literature, especially with regard to the Middle English period, probably due to the limitations of data and also because study of this development requires very cumbersome textual research. This thesis has derived and analysed the data from three large corpora in the public domain: the Middle English Grammar Corpus (MEG-C for short), the Innsbruck Computer Archive of Machine-Readable English Texts (ICAMET for short), and some selected texts from The Corpus of Middle English Prose and Verse, part of the Middle English Compendium that also includes the Middle English Dictionary. The data were analysed from three perspectives: 1) clausal type, 2) dialect, and 3) textual genre. The basic methodology for the research was to analyse the examples one by one, with special attention being paid to the peculiarities of each text. In addition, this thesis draw on some complementary – indeed overlapping -- linguistic theories for further discussion: 1) Biber’s multi-dimensional theory, 2) Ogura and Wang’s (1994) S-curve or ‘diffusion’ theory, 3) Kretzchmar’s (2009) linguistics of speech, and 4) Halliday’s (1987) notion of language as a dynamic open system. To summarise the outcomes of this thesis: 1) On variation between clausal types, it was shown that the distributional tendencies of verb types (sub, ind, mod) are different between the three adverbial clauses under consideration. 2) On variation between dialects, it has been shown that the northern area, i.e. the so-called Great Scandinavian Belt, displays an especially high comparative ratio of the inflexional subjunctive construction compared to the other areas. This thesis suggests that this result was caused by the influence of Norse, relating the finding to the argument of Samuels (1989) that the present tense -es ending in the northern dialect was introduced by the influence of the Scandinavians. 3) On variation between genres, those labelled Science, Documents and Religion display relatively high ratio of the inflexional subjunctive, while Letter, Romance and History show relatively low ratio of the inflexional subjunctive. This results are explained by Biber’s multi-dimensional theory, which shows that the inflexional subjunctive can be related to the factors ‘informational’, ‘non-narrative’, ‘persuasive’ and ‘abstract’. 4) Lastly, on the inflexional subjunctive in Late Middle English, this thesis concludes that 1) the change did not happen suddenly but gradually, and 2) the way language changes varies. Thus the inflexional subjunctive did not disappear suddenly from England, and there was a time lag among the clausal types, dialects and genres, which can be related to Ogura and Wang’s S-curve (“diffusion”) theory and Kretzchmars’s view of “linguistic continuum”. This thesis has shown that the issues with regard to the inflexional subjunctive are quite complex, so that research in this area requires not only textual analysis but also theoretical analysis, considering both intra- and extra- linguistic factors.

Egfr Activating Mutations And Their Association With Response To Platinum-doublet Chemotherapy In Brazilian Non-small Cell Lung Cancer Patients.

The aim of the study was to analyze the frequency of epidermal growth factor receptor (EGFR) mutations in Brazilian non-small cell lung cancer patients and to correlate these mutations with response to benefit of platinum-based chemotherapy in non-small cell lung cancer (NSCLC). Our cohort consisted of prospective patients with NSCLCs who received chemotherapy (platinum derivates plus paclitaxel) at the [UNICAMP], Brazil. EGFR exons 18-21 were analyzed in tumor-derived DNA. Fifty patients were included in the study (25 with adenocarcinoma). EGFR mutations were identified in 6/50 (12 %) NSCLCs and in 6/25 (24 %) adenocarcinomas; representing the frequency of EGFR mutations in a mostly self-reported White (82.0 %) southeastern Brazilian population of NSCLCs. Patients with NSCLCs harboring EGFR exon 19 deletions or the exon 21 L858R mutation were found to have a higher chance of response to platinum-paclitaxel (OR 9.67 [95 % CI 1.03-90.41], p = 0.047). We report the frequency of EGFR activating mutations in a typical southeastern Brazilian population with NSCLC, which are similar to that of other countries with Western European ethnicity. EGFR mutations seem to be predictive of a response to platinum-paclitaxel, and additional studies are needed to confirm or refute this relationship.

Fatty Acid Synthase Inhibitors Induce Apoptosis In Non-tumorigenic Melan-a Cells Associated With Inhibition Of Mitochondrial Respiration.

The metabolic enzyme fatty acid synthase (FASN) is responsible for the endogenous synthesis of palmitate, a saturated long-chain fatty acid. In contrast to most normal tissues, a variety of human cancers overexpress FASN. One such cancer is cutaneous melanoma, in which the level of FASN expression is associated with tumor invasion and poor prognosis. We previously reported that two FASN inhibitors, cerulenin and orlistat, induce apoptosis in B16-F10 mouse melanoma cells via the intrinsic apoptosis pathway. Here, we investigated the effects of these inhibitors on non-tumorigenic melan-a cells. Cerulenin and orlistat treatments were found to induce apoptosis and decrease cell proliferation, in addition to inducing the release of mitochondrial cytochrome c and activating caspases-9 and -3. Transfection with FASN siRNA did not result in apoptosis. Mass spectrometry analysis demonstrated that treatment with the FASN inhibitors did not alter either the mitochondrial free fatty acid content or composition. This result suggests that cerulenin- and orlistat-induced apoptosis events are independent of FASN inhibition. Analysis of the energy-linked functions of melan-a mitochondria demonstrated the inhibition of respiration, followed by a significant decrease in mitochondrial membrane potential (ΔΨm) and the stimulation of superoxide anion generation. The inhibition of NADH-linked substrate oxidation was approximately 40% and 61% for cerulenin and orlistat treatments, respectively, and the inhibition of succinate oxidation was approximately 46% and 52%, respectively. In contrast, no significant inhibition occurred when respiration was supported by the complex IV substrate N,N,N',N'-tetramethyl-p-phenylenediamine (TMPD). The protection conferred by the free radical scavenger N-acetyl-cysteine indicates that the FASN inhibitors induced apoptosis through an oxidative stress-associated mechanism. In combination, the present results demonstrate that cerulenin and orlistat induce apoptosis in non-tumorigenic cells via mitochondrial dysfunction, independent of FASN inhibition.

Imported Malaria In A Non-endemic Area: The Experience Of The University Of Campinas Hospital In The Brazilian Southeast.

Although malaria in Brazil almost exclusively occurs within the boundaries of the Amazon Region, some concerns are raised regarding imported malaria to non-endemic areas of the country, notably increased incidence of complications due to delayed diagnoses. However, although imported malaria in Brazil represents a major health problem, only a few studies have addressed this subject. A retrospective case series is presented in which 263 medical charts were analysed to investigate the clinical and epidemiological characterization of malaria cases that were diagnosed and treated at Hospital & Clinics, State University of Campinas between 1998 and 2011. Amongst all medical charts analysed, 224 patients had a parasitological confirmed diagnosis of malaria. Plasmodium vivax and Plasmodium falciparum were responsible for 67% and 30% of the infections, respectively. The majority of patients were male (83%) of a productive age (median, 37 years old). Importantly, severe complications did not differ significantly between P. vivax (14 cases, 9%) and P. falciparum (7 cases, 10%) infections. Severe malaria cases were frequent among imported cases in Brazil outside of the Amazon area. The findings reinforce the idea that P. vivax infections in Brazil are not benign, regardless the endemicity of the area studied. Moreover, as the hospital is located in a privileged site, it could be used for future studies of malaria relapses and primaquine resistance mechanisms. Finally, based on the volume of cases treated and the secondary complications, referral malaria services are needed in the non-endemic areas of Brazil for a rapid and efficient and treatment.

Evaluation Of Fe Uptake And Translocation In Transgenic And Non-transgenic Soybean Plants Using Enriched Stable (57)fe As A Tracer.

A tracer experiment is carried out with transgenic T (variety M 7211 RR) and non-transgenic NT (variety MSOY 8200) soybean plants to evaluate if genetic modification can influence the uptake and translocation of Fe. A chelate of EDTA with enriched stable (57)Fe is applied to the plants cultivated in vermiculite plus substrate and the (57)Fe acts as a tracer. The exposure of plants to enriched (57)Fe causes the dilution of the natural previously existing Fe in the plant compartments and then the changed Fe isotopic ratio ((57)Fe/(56)Fe) is measured using a quadrupole-based inductively coupled plasma mass spectrometer equipped with a dynamic reaction cell (DRC). Mathematical calculations based on the isotope dilution methodology allow distinguishing the natural abundance Fe from the enriched Fe (incorporated during the experiment). The NT soybean plants acquire higher amounts of Fe from natural abundance (originally present in the soil) and from enriched Fe (coming from the (57)Fe-EDTA during the experiment) than T soybean ones, demonstrating that the NT soybean plants probably absorb higher amounts of Fe, independently of the source. The percentage of newly incorporated Fe (coming from the treatment) was approximately 2.0 and 1.1% for NT and T soybean plants, respectively. A higher fraction (90.1%) of enriched Fe is translocated to upper parts, and a slightly lower fraction (3.8%) is accumulated in the stems by NT plants than by T ones (85.1%; 5.1%). Moreover, in both plants, the Fe-EDTA facilitates the transport and translocation of Fe to the leaves. The genetic modification is probably responsible for differences observed between T and NT soybean plants.

[factors Associated With Satisfaction With Life Among Elderly Caregivers And Non-caregivers].

This article seeks to investigate associations between satisfaction with life and sociodemographic variables, health conditions, functionality, social involvement and social support among elderly caregivers and non-caregivers, as well as between satisfaction and the intensity of stress in the caregiver group. A sample of 338 caregivers was selected according to two items of the Brazilian version of the Elders Life Stress Inventory. A comparison-group of elderly non-caregivers was selected at random, with a similar gender, age and income profile. Data were derived from self-reported questionnaires and scales. Elderly caregivers with low levels of satisfaction and high levels of stress revealed more symptoms of insomnia, fatigue, diseases and worse IADL performance. Those with greater satisfaction and less stress revealed a good level of social support. Insomnia, depression and fatigue were associated with low satisfaction among caregivers, and with fatigue, depression and low social support among non-caregivers. It was considered relevant that instrumental, psychological and informative support can improve the quality of life and the quality of care provided by elderly caregivers, especially if they are affected by unfavorable health and psychosocial conditions and low satisfaction with life.
