De la peur de l'infantile à la peur de l'enfant ?
Authors: Cohen-Salmon Julie
Published: December 2014

À partir de son expérience clinique, l’auteur met en évidence un mode de fonctionnement psychique opératoire proche de la perversion narcissique. L’un et l’autre auraient une valeur défensive à l’encontre de la sexualité infantile. Exprimée et agie par l’enfant dans l’institution, la sexualité infantile fragilise le narcissisme de l’adulte. Elle met notamment à l’épreuve la malléabilité de l’objet. L’objet malléable, trouvé-créé par le sujet, étaye le développement des autoérotismes. La fonction de cet objet serait avant tout de favoriser le travail de symbolisation primaire, par lequel le Moi va progressivement construire une représentation du travail psychique qu’il fournit. Ce processus d’auto-représentation va ouvrir la voie au meurtre de l’autoconservation pour laisser place à l’intégration d’une sexualité porteuse d’altérité.
Émergence des affects en musicothérapie réceptive de groupe
Authors: Duperret-Gonzalez Nicole
Published: December 2014

Confrontés à des problématiques entraînant le blocage d’affects violents chez certains de leurs patients, les psychanalystes de groupe ont parfois recours à une médiation. La musique, si le psychanalyste est musicothérapeute, peut s’avérer très efficiente, d’autant plus qu’elle est un langage à part entière : elle détient un code, signifié sur la partition musicale, et constitue de ce fait un système symbolique différent du langage parlé. La musicothérapie est une technique de psychothérapie à médiation. Dans cet article, nous évoquons un dispositif de musicothérapie réceptive psychanalytique de groupe. Puis nous présentons l’exemple d’une séance expérimentale, basée sur la proposition de quatre extraits d’œuvres analysés brièvement. Nous montrons une corrélation entre la structure de l’œuvre musicale et la thématique du discours des participants, lié à l’émergence des affects enkystés.
Les fondateurs de l'écologie corporelle : immerseurs-naturiens-émerseurs
Authors: Andrieu Bernard
Published: December 2014

Nous présentons ici trois types de fondateurs de l’écologie corporelle, les naturistes et naturiens, les immerseurs écologiques et les émerseurs de conscience. Chaque type d’expérience décrit un niveau de profondeur du corps vivant et de la conscience du corps vécu.
Écologie des interactions
Authors: Maître de Pembroke Emmanuelle
Published: December 2014

Les gestes relationnels diffèrent selon les contextes dans lesquels ils ont été incorporés. Cette incorporation n’est pas simplement de l’ordre de l’imitation, mais imprègne tout à la fois le ressenti, la conscience corporelle et l’identité, ainsi que le sens et les valeurs, dans un système complexe. Ces travaux dégagent trois niveaux de cohérence. Une cohérence interne relie les comportements aux intentions et aux valeurs de la personne. Une cohérence interpersonnelle se co-construit dans l’instant de l’échange. Enfin, une cohérence externe relie l’individu et ses milieux d’appartenance. La rencontre de systèmes culturels différents des siens provoque la redécouverte des liens de sens et la prise de conscience de ces différents niveaux écologiques.
La dimension corporelle de l'émotion sportive
Authors: Lévêque Marc
Published: December 2014

L’expression de l’émotion dans les compétitions sportives prend souvent une forme spectaculaire, intense et à dominante corporelle. Banalisée dans sa signification et peu interrogée dans les recherches, l’émotion positive est considérée comme source d’efficacité tandis que l’émotion négative doit être réprimée et éliminée. Cet article invite à considérer la construction et la signification sociales de cette expression, sa place dans la communication avec la communauté sportive environnante, enfin son lien avec les mécanismes structurels de l’économie affective. C’est l’économie psychosomatique du sujet et les places respectives du langage et du rapport au corps qui sont contenus dans cette expression corporelle. L’écoute et l’analyse de ce ressenti pour en comprendre la signification devraient être favorisées.
Le corps, matière d'exercices spirituels
Authors: Pavie Xavier
Published: December 2014

Toute la philosophie antique peut être définie comme exercice spirituel, entendu comme l’ensemble des disciplines destinées à transformer, en soi-même ou chez les autres, la manière de vivre, de percevoir le monde. Cela requiert une dimension théorique, un discours, qu’il soit intérieur ou extérieur, et une mise en œuvre pratique. Si l’aspect travail de l’esprit semble être fondamental, le corps ne l’est pas moins. L’enjeu est ici de souligner que depuis l’Antiquité jusqu’à la période contemporaine l’exercice spirituel se retrouve pleinement articulé avec des attributs corporels qui peuvent être de deux ordres. D’une part une pratique corporelle accessible à tous, comme peut l’être la marche. D’autre part une pratique corporelle où le corps est plus intensément sollicité comme à l’occasion de disciplines sportives extrêmes.
L'écologie corporelle des transes en danse
Authors: Midol Nancy
Published: December 2014

À partir de deux témoignages donnés en première personne, je questionne le surgissement de transes dans des situations d’improvisations dansées. Pour rendre le phénomène intelligible, je fais trois suggestions ou hypothèses. La première est que la métaphysique occidentale sur laquelle se fonde la pensée scientifique classique est inapte à comprendre le phénomène dans sa complexité. La deuxième est que les spiritualités autres, qui n’ont pas séparé l’humain de son milieu pour éclairer le monde et sa place dans le monde, ont développé des savoirs cliniques fondamentaux sur les transes. La troisième est que la révolution mentale des sciences contemporaines et notamment l’approche écologique s’avère la plus prometteuse pour comprendre le phénomène.
Pratiques somatiques et écologie corporelle

Je m’attacherai à explorer une manière d’aller vers une écologie corporelle, une écologie de soi. Cet article rend compte d’une expérience vécue en formation personnelle mise en lien avec une pensée élaborée au cours de mes années d’enseignement de danse contemporaine tout particulièrement. C’est au travers cette observation participante que je partage mes réflexions. J’ai pratiqué plusieurs années la gymnastique holistique du Dc Ehrenfried et suivi des stages en Feldenkrais et en Continuum Movement. Lorsque j’ai commencé à travailler en BMC, ce qui m’a particulièrement touché c’est que le travail proposé parlait de la vie.
Vivre et penser son corps
Authors: Delassus Éric
Published: December 2014

Si pour Spinoza l’esprit est l’idée du corps, il est permis d’en déduire que l’accès à la sagesse consiste dans l’élaboration, sinon d’une idée adéquate, en tout cas d’une idée aussi cohérente que possible de son corps. L’homme peut ainsi mieux comprendre comment son esprit « est uni à toute la nature », pour reprendre une expression empruntée au Traité de la réforme de l’entendement . Par exemple, le malade ou le sujet handicapé pourra plus aisément accepter les changements que subit son corps s’il est susceptible d’en produire une représentation claire et distincte. Cependant, s’il est important de bien penser son corps pour mieux le vivre, ne peut-on pas envisager qu’un processus inverse soit possible pour ceux qui n’ont pas la possibilité de concevoir une idée cohérente du corps ? Pour celui dont les fonctions cognitives ont été atteintes, n’est-ce pas en vivant plus activement son corps qu’il lui sera possible d’accéder à une perception plus juste de celui-ci ?
Déstructuration et restructuration identitaire du corps prothétique
Authors: Gourinat Valentine
Published: December 2014

L’amputation d’un membre et la perte des capacités motrices qu’elle induit entraînent bien souvent une dissolution de l’identité du patient. Dans le processus de réadaptation, l’appareillage prothétique a donc pour fonction d’aider le patient à surmonter cette double mutilation (physique et identitaire). Mais la prothèse est un objet ambivalent, à l’origine de perceptions et processus identitaires contradictoires. Elle est génératrice de souffrance et de doutes, parce qu’elle intervient forcément dans le cadre d’une expérience difficile et que son usage entraîne nombre de désagréments, mais elle est en même temps un extraordinaire outil de reconstruction, parce qu’elle permet à la personne amputée de réinvestir son propre corps, son environnement quotidien ainsi que l’espace social. À partir d’une série d’entretiens menés auprès de personnes appareillées à différents stades de leur apprentissage de la prothèse, cet article propose de mettre en lumière le parcours complexe de la réadaptation fonctionnelle et identitaire que traversent les personnes équipées d’une prothèse externe.
Les enjeux de la patrimonialisation dans la gestion du développement économique : un cadre conceptuel
Authors: Lavoie Marie
Published: December 2014

Le but de cet article est de présenter un cadre conceptuel permettant d’analyser les enjeux que soulève la patrimonialisation sur le développement économique et, par conséquent, de gérer les déséquilibres qui peuvent survenir au niveau national et international. Une stratégie patrimoniale devrait viser prioritairement le bien-être humain d’une population, mais il serait irréaliste de passer outre l’impact d’une telle stratégie sur le développement et le bien-être économique. Le cadre d’analyse développé par l’OCDE prend en compte des objectifs de croissance économique, de bien-être économique et humain. Ce cadre est opportun et particulièrement bien adapté à la mise en œuvre de la stratégie de patrimonialisation. Le concept de capital tel qu’utilisé par l’OCDE permet de lier de façon systémique les différentes influences, qu’elles soient sociales, culturelles, humaines, matérielles et naturelles, sur le développement économique et les autres formes de bien-être. En permettant de bien cerner la complémentarité entre les capitaux et les dispositions institutionnelles et juridiques, il s’avère un guide très efficace pour le processus d’élaboration des politiques publiques dans un contexte de patrimonialisation.
Safety and efficacy of human breast milk Lactobacillus fermentum CECT 5716. A mini-review of studies with infant formulae
Authors: López-Huertas E.
Published: December 2014

Human breast milk has been described as a source of lactic acid bacteria. Lactobacillus fermentum CECT5716 is a human breast milk strain whose probiotic properties, safety and efficacy has been demonstrated in vitro and in vivo, including controlled trials with human adults. Since the origin of this probiotic strain is human breast milk, we aimed to investigate the safety and efficacy of an infant and a follow-on formulas supplemented with this strain of L. fermentum. We carried out two randomised controlled trials: one trial with infants of 6-12 months of age (follow-on formula study) and another one with infants from 1 to 5 months of age (infant formula study). The results from the trials showed that the probiotic formulas were safe, well tolerated and might be useful for the prevention of community-acquired infections.
Consumption of partially hydrolysed guar gum stimulates Bifidobacteria and butyrate-producing bacteria in the human large intestine

Published: December 2014

Partially hydrolysed guar gum (PHGG) is a water-soluble dietary fibre that is non-digestible in the upper gastrointestinal tract. It is believed that PHGG benefits the health of hosts by altering the colonic microbiota and stimulating short-chain fatty acid (SCFA) production. However, it remains unclear which bacteria ferment PHGG in the human large intestine. In this study, the effect of PHGG on faecal bacteria was analysed to specify the bacteria that contribute to the fermentation of PHGG in the human large intestine. Ten healthy volunteers consumed PHGG (6 g/day) for 2 weeks. Faeces were collected at 2 weeks prior to consumption, at the end of 2 weeks of consumption, and 2 weeks after consumption of PHGG. Bacterial DNA was extracted from these collected faeces and subjected to real-time PCR using bacterial group- or species-specific primers. The copy number of the butyryl-CoA CoA-transferase gene and the 16S rRNA gene copy numbers of Bifidobacterium, the Clostridium coccoides group, the Roseburia/ Eubacterium rectale group, Eubacterium hallii, and butyrate-producing bacterium strain SS2/1 were significantly increased by the intake of PHGG. Other bacteria and bacterial groups were not significantly influenced by the intake of PHGG. It was believed that the Roseburia/E. rectale group bacteria, Bifidobacterium, the lactate-utilising, butyrate-producing bacteria, E. hallii and bacterium strain SS2/1, would contribute to the fermentation of PHGG in the human large intestine. PHGG may benefit health by stimulating Bifidobacterium and butyrate-producing bacteria in the human large intestine.
HUMAN GASTROINTESTINAL DATA ANALYSIS BASED ON WAVELET TRANSFORM-FRACTAL ALGORITHM CHARACTERIZED BY WIRELESS CAPSULE

Published: December 2014

Background: Gastrointestinal tract pressure information can reflect the dynamic disorder of gastrointestinal tract physiological and pathological changes, which is important in early diagnosis and treatment of gastrointestinal diseases. However, the rule of human gastrointestinal activities under his normal state is still not clear. The purpose of this paper is to find some rules of gastrointestinal activities using wavelet transform-fractal algorithm and provides a reference for the diagnosis of gastrointestinal disease. Methods: Data from 16 healthy subjects (13 men and three women) aged 18–35 years were analyzed. The key challenges on the data processing were filtering, features extraction, information evaluation and providing the reference conclusion which were resolved by employing wavelet decomposition, fractal algorithm etc. Key Results: About 94% of the subjects gastrointestinal activities follow the rule that the colonic activities in the digestive period are the roughest with the largest box dimension, closely followed by small intestinal activities with gastric activities ranking third with the smallest box dimension, which is never revealed before. Moreover, for the same person the gastrointestinal activities in the digestive period are rougher than in the inter-digestive period, as the box dimension of gastrointestinal activities in the digestive period is larger than in the inter-digestive period. Conclusions and Inferences: The results show that the wavelet transform-fractal algorithm provides a new way to research human gastrointestinal activities.
IN SITU MONITORING OF MEAN BLOOD OXYGEN SATURATION USING EXTENDED MODIFIED LAMBERT BEER MODEL
Authors: Huong Audrey K. C. , Ngu Xavier T. I.
Published: December 2014

We present the use of Extended Modified Lambert–Beer model for optical monitoring of mean blood oxygen saturation ( S m O 2) via a fitting procedure. This work focuses on the absorption characteristics of hemoglobin derivatives in the wavelength range of 520–600 nm to give the best estimates of S m O 2. The study of the feasibility of applying this analytic method to skin oximetry is via spectroscopy data collected from fingertips of four healthy volunteers both at rest and during arterial blood occlusion condition. The results revealed a decrease in the mean of mean and standard deviation of S m O 2 value of fingertips from 94.5 ± 2.19% when volunteers were at rest to 56.76 ± 5.8% during the arterial blood occlusion measurement. The larger variation in the value estimated for blood occlusion condition could be a result of differences in volunteers' physical fitness and hypertension status. These estimated S m O 2 values agreed reasonably well with the value reported in most of the previous studies. This work concluded that the proposed technique can potentially be used as a complementary technique to clinical assessment of skin grafts and burnt skin.
DESIGN OF A RING-TYPE REFLECTION PULSE OXIMETER WITH A PARABOLIC REFLECTOR
Authors: Lu Chun-Hao , Lin Jiun-Hung , Huang Han-Ming , Huang Cheng-Yang , Tai Cheng-Chi
Published: December 2014

A pulse oximeter is a noninvasive instrument used in clinical medicine to monitor arterial oxygen saturation. Fingertip-type pulse oximeters are popular, but their inconvenience for long-term monitoring in daily life means that other types of wearable pulse oximeters, such as a ring-type reflection pulse oximeter, needs to be developed. However, designing a ring-type pulse oximeter for measuring the oxygen saturation is difficult due to the complex tissue architecture of the finger base. This study used human tissue simulations to evaluate the practicability of a ring-type reflection pulse oximeter design. Moreover, given that the collection of diffusely reflected light can be enhanced by using a parabolic reflector, the efficacy of a ring-type reflection pulse oximeter with a parabolic reflector was also evaluated.

Published: December 2014

To develop a more convenient electromyography (EMG) signal acquisition system for masticatory muscles (MMs) will have implication for the diagnosis of disease of stomatological system and functional reconstruction in dentistry. This study attempted to design a multi-channel MM surface electromyography (s-EMG) signal acquisition system which has high common mode rejection ratio (CMRR) and preamplifier system. In this system, a USB graphical interface technology on windows operating system was specifically designed and s-EMG data were analyzed by a combination of time domain, frequency domain, time-frequency, several spectral analysis, wavelets and other special algorithms under multi-parameter. Then the EMG data from some patients with stomatological dysfunction in temporomandibular joint (TMJ) clinic and a control group from dental school students were acquired and analyzed. The data indicate that the s-EMG signal acquisition system which has been built is simple and useful in aiding diagnosis and treatment evaluation of temporomandibular disorders.
Stable Interactions and Sustained TCR Signaling Characterize Thymocyte–Thymocyte Interactions that Support Negative Selection
Authors: Melichar Heather J. , Ross Jenny O. , Taylor Kayleigh T. , Robey Ellen A.
Published: December 2014

Negative selection is one of the primary mechanisms that render T cells tolerant to self. Thymic dendritic cells play an important role in negative selection, in line with their ability to induce migratory arrest and sustained TCR signals. Thymocytes themselves display self-peptide/MHC class I complexes, and although there is evidence that they can support clonal deletion, it is not clear whether they do so directly via stable cell–cell contacts and sustained TCR signals. In this study, we show that murine thymocytes can support surprisingly efficient negative selection of Ag-specific thymocytes. Furthermore, we observe that agonist-dependent thymocyte–thymocyte interactions occurred as stable, motile conjugates led by the peptide-presenting thymocyte and in which the trailing peptide-specific thymocyte exhibited persistent elevations in intracellular calcium concentration. These data confirm that self-Ag presentation by thymocytes is an additional mechanism to ensure T cell tolerance and further strengthen the correlation between stable cellular contacts, sustained TCR signals, and efficient negative selection.

Current subunit vaccines are incapable of inducing Ag-specific CD8+ T cell cytotoxicity needed for the defense of certain infections and for therapy of neoplastic diseases. In experimental vaccines, cytotoxic responses can be elicited by targeting of Ag into cross-presenting dendritic cells (DC), but almost all available systems use target molecules also expressed on other cells and thus lack the desired specificity. In the present work, we induced CD8+ T cell cytotoxicity by targeting of Ag to XCR1, a chemokine receptor exclusively expressed on murine and human cross-presenting DC. Targeting of Ag with a mAb or the chemokine ligand XCL1 was highly specific, as determined with XCR1-deficient mice. When applied together with an adjuvant, both vector systems induced a potent cytotoxic response preventing the outgrowth of an inoculated aggressive tumor. By generating a transgenic mouse only expressing the human XCR1 on its cross-presenting DC, we could demonstrate that targeting of Ag using human XCL1 as vector is fully effective in vivo. The specificity and efficiency of XCR1-mediated Ag targeting to cross-presenting DC, combined with its lack of adverse effects, make this system a prime candidate for the development of therapeutic cytotoxic vaccines in humans.
MiR-127 Modulates Macrophage Polarization and Promotes Lung Inflammation and Injury by Activating the JNK Pathway

Published: December 2014

A polarized macrophage response is presumed to have a pivotal role in a variety of immunological pathophysiology. However, the molecular mechanism underlying macrophage functional shaping remains largely unknown. In this study, we reveal a pivotal role of miR-127 in macrophage development and thereby the pathogenesis of inflammation and lung injury. In particular, miR-127 was demonstrated to be prominently induced upon TLR engagement and repressed by the M2-prone cytokines. Enforced expression of miR-127 in macrophages resulted in significantly increased production of proinflammatory cytokines, whereas deletion of miR-127 impaired M1 gene expression and led to a M2-biased response. Accordingly, intratracheal administration of miR-127 resulted in an exaggerated pulmonary inflammation and injury. Conversely, antagonizing of miR-127 suppressed production of the proinflammatory cytokines and rendered the mice more refractory to the inflammation-associated pathology. Mechanistically, miR-127 demonstrated to target B cell lymphoma 6 (Bcl6) and remarkably downregulated its expression and subsequently dual specificity phosphatase 1 (Dusp1), which in turn enhanced the activation of JNK kinase and hence the development of proinflammatory macrophages. Thereby, reconstitution with the expression of Bcl6 or Dusp1 or inhibition of JNK activity impaired miR-127–mediated skewing of M1 proinflammatory macrophages, whereas interference of Bcl6 or Dusp1 expression abrogated the anti-inflammatory property of anti–miR-127. Together, these data establish miR-127 as a molecular switch during macrophage development and as a potential target for treatment of inflammatory diseases.
The palynostratigraphy, age, and environment of strata penetrated by the Mallik 5L-38 gas-hydrate research well, Northwest Territories, determined by differentiating the recycled and contemporaneous palynomorphs
Authors: White J M
Published: December 2014

Quantitative palynostratigraphy of the Mallik 5L-38 well provides insight into palynomorph recycling and a Late Eocene age for the basal coals. Samples from 450 m to 900 m yielded a fraction on the 180 ?m screen having a high concentration of recycled
palynomorphs, releasable by standard oxidation. The fraction that passed through the screen was not oxidized and yielded more in-place palynomorphs. This observation may affect interpretation of other regional upper Cenozoic studies of oxidized samples. The 0-270 m interval is interpreted to be late
Pliocene to Pleistocene. The regional erosional unconformity below the Iperk Sequence is identified at 340 m, with other possible unconformities at 445 m and 550 m. The interval from 340 m to 700 m is thought to be Early Miocene. The 700-900 m interval is tentatively identified as Oligocene. Climate
proxy ratios, compared with those of Mallik 2L-38 well between 670 m and 900 m are inconsistent, possibly due to low palynomorph counts or a change from a coherent Late Eocene record to a noisy Oligocene and younger record. An erosional unconformity near 930 m may have resulted from sea-level
decline due to earliest Oligocene glaciation in Antarctica. Core samples from coal beds between 933.65 m and 1081.90 m yielded Late Eocene palynomorphs unlikely to be recycled, and some pollen associated with earlier Eocene ages. The coal swamps seem to be an environment where relict species can
persist. A warm paleoclimate is indicated, consistent with an Eocene age.
Quaternary unconsolidated sediment thickness on the Grand Banks of Newfoundland and northeast Newfoundland Shelf; a GIS database
Authors: King E L
Published: December 2014

The thickness of Quaternary unconsolidated sediments (overburden) across the Grand Banks of Newfoundland and the Northeast Newfoundland shelf has been compiled and incorporated into a GIS-based geodatabase. It is derived from interpretation of a vast grid of high
and mid-resolution seismic reflection profiles collected over about 40 years by the Geological Survey of Canada-Atlantic. This spatial database is in the form of spot thicknesses along survey tracks and thickness-classed zonation interpolated from these points. It comprises over 85 000 point
thickness entries, each identifying the stratigraphic unit (or range in units) measured, a code linking to the raw data source, thickness in metres and milliseconds, notes on the source of interpretation and the process and positional accuracy, and generally the stratigraphic unit underlying the
sediment at that position. Most records document only the total Quaternary thickness. A total Quaternary thickness zonation map (polygons/contours in six thickness classes) adds considerable interpretive value to the spot thickness measurements. Control for extrapolation and interpolation of the
spot thicknesses came from bathymetric shaded relief images (mainly low resolution) where, for example, basins, valleys and ridges, near-seabed bedrock expression and other morphological elements helped provide spatial control for sediment thickness distribution. Till from the last glaciation is
dominant volumetrically and locally stacked tills, presumably from older glaciations/statials are also identified. However the thickness database also includes a differentiation of eight separate sediment facies or stratigraphic units. These records are only compiled from select datasets where the
appropriate raw data (generally ultra-high resolution profiles) were in a suitable format. This product complements other new map products from the area, both bedrock and surficial geological and a surface and sub-surface geo-features geodatabase.
Guide de production d'imagerie sonar à l'aide d'outils grand public - Étude de cas à la rivière des Outaouais à Quyon, Québec
Authors: Prévost C
Published: December 2014

Natural Resources Canada (NRCAN) has the mandate of providing essential geographic information. An improved knowledge of our physical environment represents one of the basis of this mandate. This essential baseline information is generally associated with the
terrestrial or landmass environment. The geographic knowledge of the underwater environment often represents the weak segment in the chain linking terrestrial units together. In the geohazard domain, also a NRCAN mandate, the development of mitigation strategies for geohazards, including landslide,
rely on accurate underwater terrain information.
Recently, there have been consumer grade, low cost, side scan imaging sonars capable of imaging the floor of a lake, a river or a coastline. These tools are targeted for sport fishing and diving markets but they are also capable of partly providing an image view of the lake and river floor. These
tools, which are versatile, portable and easy to use can have scientific and technological applications, such as the subsurface geomorphological mapping of lake and river floors: bedrock outline, contact between sediments and bedrock, lineaments, sand waves location and various forms of erosion /
deposit. Therefore, low cost consumer grade side scan sonars can partly fill the technology / scientific information gap for essential geographic information and geohazards, and are particularly well suited for the Canadian North and in remote or difficult to access areas.
A case study was carried out in Quyon Qc. area, in the Ottawa region, to determine the potential of these tools for the geomorphological mapping of a river floor, as it may relate to landslide characterization in the area. This document explains the main constraints for a high quality survey and
recommends ways to overcome them. Several image examples and interpretation are presented as well as the findings resulting from this case study.
Macro-level drivers of multidimensional poverty in sub-Saharan Africa: Explaining change in the Human Poverty Index
Authors: Prince Heath
Published: December 2014

Poverty is increasingly recognised as a multidimensional phenomenon in the development literature, encompassing not only income, but also a range of factors related to broadening an individual’s freedoms to live a life of their own choosing. Poverty so understood suggests that alternative approaches to poverty measurement reflecting this multidimensionality may point towards alternative policies for poverty alleviation. The imperative to reinforce pro-poor policy development in sub-Saharan Africa with evaluation findings that reflect improvements in well-being, rather than solely improvements in national economies, has become self-evident as, despite decades of market-led development policies, much of the subcontinent remains mired in deprivation. As recognised by the 2014 African Evaluation Association’s biannual conference, fresh thinking and new evaluation metrics are required in order to create policies that more effectively increase well-being. This article explores the factors that may account for changes in one metric of multidimensional poverty in developing countries, the United Nation Development Program’s Human Poverty Index (HPI), and will be primarily concerned with measuring the effects on the HPI of policies and activities that relate to, or are explicitly meant to encourage, economic growth, increased literacy and improved health. The study focuses on the outcomes of a panel data set, created for the purpose of this study, of HPI scores for a set of 47 sub-Saharan countries, between 1990 and 2010, and a range of indicators that the development literature and theory suggest should have an effect on income poverty, asking, what is the relationship between these indicators and multidimensional poverty? A parallel set of models has been developed to measure the response of household consumption expenditure to changes in economic growth and human capabilities indicators. All models are estimated using fixed effects estimators and cluster robust standard errors in Stata 12. Consistent with the development literature, household expenditure appears to be significantly and positively related to changes in gross domestic product (GDP) per capita. However, when the HPI is regressed on GDP per capita, no statistically significant relationshipis observed, even when controlling for a range of other indicators, calling into question the relationship between economic growth and well-being in much of sub-Saharan Africa. This finding suggests that development policies that focus primarily on economic growth as a means to addressing multidimensional deprivation may be misplaced.
Potential Health Effects Associated with Dermal Exposure to Occupational Chemicals
Authors: Anderson Stacey E. , Meade B. Jean
Published: December 2014

There are a large number of workers in the United States, spanning a variety of occupational industries and sectors, who are potentially exposed to chemicals that can be absorbed through the skin. Occupational skin exposures can result in numerous diseases that can adversely affect an individual's health and capacity to perform at work. In general, there are three types of chemical-skin interactions of concern: direct skin effects, immune-mediated skin effects, and systemic effects. While hundreds of chemicals (metals, epoxy and acrylic resins, rubber additives, and chemical intermediates) present in virtually every industry have been identified to cause direct and immune-mediated effects such as contact dermatitis or urticaria, less is known about the number and types of chemicals contributing to systemic effects. In an attempt to raise awareness, skin notation assignments communicate the potential for dermal absorption; however, there is a need for standardization among agencies to communicate an accurate description of occupational hazards. Studies have suggested that exposure to complex mixtures, excessive hand washing, use of hand sanitizers, high frequency of wet work, and environmental or other factors may enhance penetration and stimulate other biological responses altering the outcomes of dermal chemical exposure. Understanding the hazards of dermal exposure is essential for the proper implementation of protective measures to ensure worker safety and health.

For an ideal of smooth functions

\mathfrak a

that is either Łojasiewicz or weakly Łojasiewicz, we give a complete characterization of the ideal of functions vanishing on its variety

\mathcal I(\mathcal Z (\mathfrak a))

in terms of the global Łojasiewicz radical and Whitney closure. We also prove that the Łojasiewicz radical of such an ideal is
analytic-like
in the sense that its saturation equals its Whitney closure. This allows us to revisit Nullstellensatz results due to Bochnak and Adkins–Leahy and to resolve positively a modification of the Nullstellensatz conjecture due to Bochnak.

The return on investment for undergraduate degrees in hospitality and tourism management
Authors: Tasci Asli D. A. , Pizam Abraham , Croes Robertico , Chen Po-Ju
Published: December 2014

Increasing concerns regarding the value of higher education in the United States have motivated several organizations to calculate the return on investment (ROI) for college education by employing diverse methodologies. This study evaluates these methodologies by using data from a survey of alumni of Rosen College of Hospitality Management at the University of Central Florida. The results reveal that the highly publicized low ROI for college education might be inaccurate, confusing, and misleading for several reasons, among which is the assumption of zero income while studying, causing debt to be the total of a student’s expenses. Data reveal that Rosen College graduates who work in mandatory paid internships and hold part-time jobs could be debt-free within 2 years if they pay 20% of their salary toward their debt. A more valid and reliable education ROI calculation method is proposed for the United States and other countries where students must pay tuition and acquire loans to cover their educational expenses.

Este trabalho analisa a formação e constituição dos depósitos derivados do assoreamento no Reservatório Santa Bárbara (Pelotas - RS). Desta forma, foi feito o mapeamento do uso e ocupação do solo da bacia hidrográfica deste corpo d’água, referente a duas épocas: 1988 e 2002. Posteriormente, os depósitos foram caracterizados e classificados, de acordo com sua estrutura, gênese e composição. Para isto, foi feito testemunhagem na confluência de cada um dos cinco afluentes. Os resultados obtidos foram a quantificação das classes de uso e ocupação do solo, a identificação e classificação dos depósitos tecnogênicos e a verificação, nestes, de fases de menor e maior antropização.
Mineração do ouro no período colonial: alterações paisagísticas antrópicas na serra de Ouro Preto, Minas Gerais

A descoberta do ouro nas cabeceiras da bacia do ribeirão do Carmo em fins do século XVII provocou um processo migratório na província de Minas Gerais e o surgimento de vários povoados, que originaram posteriormente as vilas que hoje são as cidades de Ouro Preto e Mariana. As atividades de mineração ocorreram tanto no leito dos cursos de água como nas vertentes da serra de Ouro Preto e no interior dos maciços, neste caso por trabalhos subterrâneos. Entre os processos utilizados, o desmonte manual ou hidráulico dos depósitos de vertentes e do substrato mais friável foi o procedimento que deixou os vestígios mais marcantes das atividades mineiras, representados por grandes áreas escavadas e totalmente modificadas em relação à sua morfologia e estabilidade originais. Os principais sítios destas atividades, pela extensão e volume de material mobilizado, estão nas vertentes da serra nos atuais limites a norte da área urbana de Ouro Preto, já parcialmente ocupada pela malha urbana, e nas encostas e topos a montante da área urbana do distrito de Passagem de Mariana (Mariana), cobrindo uma área total de cerca de 300 hectares. Estas áreas foram delimitadas e caracterizadas como áreas de erosão tecnogênica, sendo possível em alguns locais a reconstituição da paisagem original a partir de testemunhos topográficos e a estimativa do volume de material retirado. Porém, os depósitos correlatos a estes processos erosivos foram destruídos pela dragagem do ribeirão na década de 1980 por companhia de mineração. Esta paisagem modificada tem importância histórica e cultural para as cidades e a região, e deve ser integrada ao seu patrimônio geomineiro como testemunho da capacidade de alteração do meio físico pela ação antrópica, mesmo com técnicas primitivas.

Este trabalho visa apresentar depósitos tecnogênicos como testemunhos e indicadores de ações antrópicas de urbanização, utilizando a implantação de loteamento no município de Guarulhos (SP) como estudo de caso. A região objeto de estudo possui área degradada que foi terraplenada, porém embargada pela prefeitura e posteriormente abandonada. Os processos de erosão e assoreamento que se manifestaram produziram os referidos depósitos. Este estudo foi conduzido pela abordagem geotecnogênica, que considera o homem como agente geológico com relevância para a caracterização de depósitos tecnogênicos. A situação atual dos depósitos indica tendência à estabilização dos processos, e suas camadas testemunham a história dinâmica de tais processos.
Antropoceno - Tecnógeno: o Brasil avança nas pesquisas

Quando o editor me convidou para realizar um volume temático da Revista sobre o Tecnógeno não foi difícil aceitar o desafio, pois já havíamos realizado o Primeiro Encontro Brasileiro do Tecnógeno em 2005, durante o X Congresso da ABEQUA, em Guarapari.  Neste mesmo ano, o livro da ABEQUA – Quaternário do Brasil – estava sendo lançado, contemplando um capítulo sobre o tema – Tecnógeno: Registros da Ação Geológica do Homem. Além disso, nos incentivou, também, o fato de que a comunidade científica está discutindo a definição de uma nova época – o Antropoceno, no âmbito de um Grupo de Trabalho da International Commission on Stratigraphy (ICS) da International Union of Geological Science (IUGS). Temos certeza que volume contribuirá para os debates do grupo, que concluirá seus trabalhos em 2016.A proposta do Tecnógeno é de Ter-Stepanian, feita em 1989, no âmbito da IAEG - International Association of Engineering Geology, considerando o Holoceno como o começo do Tecnógeno, há cerca de 10.000 anos antes do presente, tendo como referência a Revolução Agrícola, a primeira revolução tecnológica, a ser concluído quando todas as paisagens naturais tiverem sido alteradas pela Humanidade. A proposta do Antropoceno é de Stoermer e Crutzen, feita em 2000, considerando seu início na Revolução Industrial, na Europa em torno do ano de 1800, considerando que as transformações antrópicas atingiram a escala planetária. Embora ainda não tenha sido formalmente definido como unidade da escala de tempo geológico, o termo Antropoceno já vem sendo largamente aplicado no mundo científico e foi adotado definitivamente pela mídia.Neste semestre de 2014, quando a ABEQUA comemora os seus 30 anos, a publicação do volume especial “Antropoceno – Tecnógeno” é como um presente para todos nós associados para enriquecermos nosso debate sobre as transformações ambientais do passado, do presente e do futuro e, assim, aprofundarmos nossas reflexões sobre nosso papel como cientistas do Quaternário, sobre a vida da nossa Terra.Permanecerei, por todo o Quaternário, grato ao Rodolfo J. Angulo que proporcionou esta realização; a todos os autores e revisores, que contribuíram de forma inestimável; a Maria Cristina de Souza, pela ajuda permanente aos meus pedidos de socorro, solucionando todos os problemas, e a Claudia Ortiz pelo esforço de editoração. Finalmente, registro meus profundos agradecimentos à minha esposa Adriana Oliveira que, entusiasmada por sua pesquisa de mestrado sobre depósitos tecnogênicos, me deu o apoio decisivo para que eu pudesse cumprir mais uma missão nossa, de forma consistente do início ao fim.
ESTIMATIVA DO POTENCIAL DE PRODUÇÃO DE BIOGÁS E ENERGIA NA INDÚSTRIA DE ABATE DE FRANGOS NO BRASIL
Authors: Malaggi Michelle , Souza Samuel Nelson Melegari de
Published: December 2014

O presente trabalho teve como objetivo estimar a produção de biogás proveniente das indústrias brasileiras de abate de frangos e a sua capacidade de produzir energia por meio do biogás. Alguns dos dados base foram obtidos junto a uma agroindústria avícola que serviu como referência. A empresa possui um abate médio de 266 mil frangos por dia, com sistema de tratamento de efluentes baseado no biodigestor modelo canadense, o qual através da degradação anaeróbia produz o biogás como resultado final.  A indústria de abate de frangos produz em média 743,77 m3.dia-1 de biogás, ou seja, gera 2,78 m3.dia-1 por animal abatido. Cuja conversão em eletricidade através de motores geradores é de 1,47 kWh. Com estes dados e outros obtidos em literaturas pertinentes, conseguiu-se estimar que o Brasil possui capacidade para gerar 39.335,44 mil m3.dia-1 de biogás e de produzir  57.823,11 kWh de energia elétrica.

A intensificação da suinocultura no país tem levado a um aumento deresíduos destinados incorretamente, uma alternativa viável é a utilização da água residuária da suinocultura (ARS) por meio da fertirrigação. Deste modo, o objetivo deste trabalho foi avaliar em uma área de cultivo de pinhão manso, os efeitos da água residuária da suinocultura sobre a população da macrofauna em solo. O experimento instalado no Colégio Agrícola Estadual Adroaldo Augusto Colombo em Palotina-PR, em uma área com cultivo de pinhão-manso, possuindo 216 m², sendo dividida em 18 parcelas, com três repetições e seis tratamentos (0, 40, 80, 120, 160, 180 m3.ha-1) com diferentes quantidades de ARS. Foram instaladas armadilhas de queda em cada uma das parcelas e realizadas coletadas uma vez por semana nas três semanas antecedentes á aplicação, bem como nas três semanas posteriores. Observou-se de modo geral que a utilização de água residuária de suinocultura nas doses utilizadas foi prejudicial a macrofauna do solo,  diminuindo a densidade destes organismos e consequentemente interferindo na  qualidade.

A produção de suínos brasileira é uma atividade antiga, porém não havia alta concentração de dejetos como nos dias atuais, o sistema de confinamento de criação de animais se alastrou e proporcionalmente a produção de dejetos também. Cada fase da vida de um suíno produz uma quantidade de dejetos diferente, que varia de acordo com o peso, sexo, raça, dieta e digestibilidade do animal. Esses resíduos possuem uma alta capacidade poluidora se eliminada no ambiente sem nenhum tratamento, atualmente existem técnicas para tratar os dejetos para que haja um reaproveitamento e/ou possam ser descartadas sem causar nenhum dano na natureza. Depois de tratados esses resíduos podem ser utilizados como biofertilizantes no solo, o gás que provém da decomposição de bactérias aeróbicas e anaeróbicas em biodigestores possui alto valor energético que pode ser usado na geração de energia. Este artigo possui como principal objetivo fazer um levantamento básico sobre as características dos dejetos de suínos como também sua utilização sustentável após receber tratamento adequado.
AVALIAÇÃO DA ESTABILIDADE OXIDATIVA DO BIODIESEL DE SOJA (Glycine max L.) NA PRESENÇA DE ANTIOXIDANTES NATURAIS OBTIDOS DAS FOLHAS DE ACEROLA (Malpighia glabra L.) UTILIZANDO CO2 SUPERCRÍTICO

Biodiesel pode ser obtido de fontes renováveis, como óleos vegetais e devido ao seu perfil favorece a sua oxidação, sendo necessário acrescentar antioxidantes. Os mais utilizados são BHT, TBHQ e BHA. Os compostos fenólicos são importantes devido às suas propriedades antioxidantes. A aceroleira (Malpighia glabra L.) produz um fruto rico em vitamina C sendo cultivada em várias regiões do país. O objetivo desse trabalho foi avaliar a estabilidade oxidativa do Biodiesel na presença de antioxidantes sintético TBHQ e naturais dos extratos das folhas de Acerola obtidos com CO2 supercrítico em condições de temperatura e pressão variadas, utilizando Rancimat® para medição. Os melhores resultados foram para o Biodiesel acrescido de TBHQ. Os extratos nas condições 40 °C e 150 bar e 60 °C e 250 bar apresentaram tempo de indução maior que o controle.
