Desafios na execução do atendimento socioeducativo de jovens em privação de liberdade
Authors: Francisco Julio Cesar , Onofre Elenice Maria Cammarosano
Published: February 2019

O artigo trata do trabalho pedagógico realizado em unidade de internação de jovens em privação de liberdade na região de Fortaleza, estado do Ceará, Brasil, e de alguns desafios do Sistema Socioeducativo. Os procedimentos metodológicos utilizados na investigação são de caráter qualitativo e se utilizou da análise de conteúdo de Bardin (2010) no processo de coleta, organização e análise dos dados. Os resultados da pesquisa identificam atuações na gestão do atendimento socioeducativo fragmentadas e desconexas da rede de serviços públicos, num processo de criminalização e institucionalização de jovens, através de paradigma tradicional e repressivo dentro da segurança pública, delegando à polícia dois fazeres: (i) apreensão de populações pobres da periferia pelo cometimento de ato infracional; e (ii) uso desproporcional de força violenta na contenção dos conflitos dentro de unidade de internação, em vista de harmonia, vigilância e adaptação no confinamento.
Adaptação de materiais/recursos na educação de surdos: uma revisão bibliográfica
Authors: Da Costa Larissa , Santos Lara Ferreira dos
Published: February 2019

O presente estudo visou analisar os materiais e conteúdos pedagógicos pensados para alunos surdos em contexto de educação inclusiva bilíngue, visando identificar quais estratégias e materiais didáticos são atualmente utilizados e disponibilizados para estes alunos. Este trabalho justifica-se por pretender uma revisão e análise sobre as mudanças que vêm sendo propostas na educação para atender as especificidades deste alunado, a partir da publicação do Decreto 5.626, do ano de 2005. Realizou-se um levantamento bibliográfico realizado nos periódicos Portal de Periódicos CAPES e Scielo, no período de doze anos, sendo de 2005 a 2017. Os dados revelaram que há pouquíssimos resultados; acredita-se que muito se tem discutido sobre questões como a educação inclusiva, e materiais e/ou recursos adaptados, entretanto, quando relacionados à temática surdez, tais registros tornam-se bastante escassos. Com a vigência do Decreto 5.626 a Libras passou a ter maior relevância nas adaptações realizadas, bem como na produção de softwares que atendam alunos com deficiência. Todavia apenas inserir a Libras como forma de “adaptação” de materiais é insuficiente, pois esta, obrigatoriamente, deve ser o principal meio de acessibilidade.

Authors: Mesquita Rafael
Published: February 2019

This essay analyzes how traditional media has dealt with the arrival of the internet age, examining its reactions and efforts to adapt to this new environment. For such, we will explore the case of the French daily Le Monde, which carries a long and renowned tradition in print and, therefore, faced numerous challenges to adjust itself to the digital domain, having to overcome barriers in its organization culture, newsroom workflow and business models until a suitable strategy was found to ensure its competitiveness. The investigation is supported by historical bibliographic review and original interviews with personnel from the media group.
A Rhetorical Analysis of English and Persian Online Comments on the News Articles Related to Iran’s Nuclear Issue
Authors: Kafi Mohsen , Irajzad Fatemeh , Shahriari Hesamoddin
Published: February 2019

The comments section of news articles is intended for the public to share their views on posted news stories. Accordingly, this section has been subject to numerous analyses from a wide range of perspectives. The current study analyzes the tone and purpose of comments posted on news articles dealing with Iran’s nuclear issue. The data consisted of 150 online comments in English and 150 in Persian. The comments were taken from three news websites in English and three in Persian. These websites were chosen based on their different political leanings in order to take account of the various approaches to Iran’s disputed nuclear talks. The results did not indicate a significant difference between the tone of English and Persian comments, but the purposes intended by English and Persian comments varied extensively. It was also found that the political leaning of news agencies is a major cause of the observed differences.
Los emigrantes argentinos y la construcción de identidades nacionales en soportes de Internet
Authors: Busso Mariana Patricia
Published: February 2019

En este artículo se analizan las construcciones identitarias de los emigrantes argentinos hacia España e Italia realizadas discursivamente en soportes de Internet, durante el período 2001-2005. A partir de reconocer que en ellos se producen particulares dinámicas de establecimiento de vínculos e identidades colectivas, se dará cuenta de las construcciones discursivas mediante las que se elaboró en distintos foros de Internet a la argentinidad como una dimensión identitaria en sí misma, que fundó a su vez dos grandes caracterizaciones: el migrante argentino como involucrado o prescindente en relación a su país de origen, y aquél que hace de su calificación del propio ser argentino un tópico de identificación y debate.
The fish in the creek is sentient, even if I can’t speak with it
Authors: Woodruff Michael L.
Published: February 2019

Abstract: In this paper I argue that Velmens’ reflexive model of perceptual consciousness is useful for understanding the first-person perspective and sentience in animals. I then offer a defense of the proposal that ray-finned bony fish have a first-person perspective and sentience. This defense has two prongs. The first prong is presence of a substantial body of evidence that the neuroanatomy of the fish brain exhibits basic organizational principles associated with consciousness in mammals. These principles include a relationship between a second-order sensory relay, the preglomerular complex, and the fish pallium which bears a resemblance to the relationship between the mammalian thalamus and the neocortex, the existence of feedback/feedforward and reentrant circuitry in the pallium, and structural and functional differences among divisions of the fish pallium. The second prong is the existence of behaviors in fish that exhibit significant flexibility in the presence of environmental change and require relational learning among stimuli distributed in space, over time, or both. I conclude that, although they are instantiated differently, a first-person perspective and sentience are present in fish.
The projective theory of consciousness: from neuroscience to philosophical psychology
Authors: Pereira Jr. Alfredo
Published: February 2019

Abstract: The development of the interdisciplinary areas of cognitive, affective and action neurosciences contributes to the identification of neurobiological bases of conscious experience. The structure of consciousness was philosophically conceived a century ago (HUSSERL, 1913) as consisting of a subjective pole, the bearer of experiences, and an objective pole composed of experienced contents. In more recent formulations, Nagel (1974) refers to a “point of view”, in which qualitative experiences are anchored, while Velmans (1990, 1993, 2009, 2017) understands that phenomenal content is composed of mental representations “projected” to the space external to the brains that construct them. In Freudian psychology, the conscious mind contains a tension between the Id and the Ego (FREUD, 1913). How to relate this bipolar structure with the results of neuroscience? I propose the notion of projection [also used by Williford et al. (2012)] as a bridge principle connecting the neurobiological systems of knowing, feeling and acting with the bipolar structure. The projective process is considered responsible for the generation of the sense of self and the sense of the world, composing an informational phenomenal field generated by the nervous system and experienced in the first-person perspective. After presenting the projective hypothesis, I discuss its philosophical status, relating it to the phenomenal (BLOCK, 1995, 2008, 2011) and high-order thought (ROSENTHAL, 2006; BROWN, 2014) approaches, and a mathematical model of projection (RUDRAUF et al., 2017). Eight ways of testing the status of the projective hypothesis are briefly mentioned.
How to investigate perceptual projection: a commentary on Pereira Jr., “The projective theory of consciousness: from neuroscience to philosophical psychology”
Authors: Velmans Max
Published: February 2019

Abstract: This commentary focuses on the scientific status of perceptual projection-a central feature of Pereira’s projective theory of consciousness. In his target article, he draws on my own earlier work to develop an explanatory framework for integrating first-person viewable conscious experience with the third-person viewable neural correlates and antecedent causes that form conscious experience into a bipolar structure that contains both a sense of self (created by interoceptive projective processes) and a sense of the world (created by exteroceptive projective processes). I stress that perceptual projection is a psychological effect (not an explanation for that effect) and list many of the ways it has been studied within experimental psychology, for example in studies of depth perception in vision and audition and experiences of depth arising from cues arranged on two-dimensional surfaces in stereoscopic pictures, 3D cinemas, holograms, and virtual realities. I then juxtapose Pereira’s explanatory model with two other models that have similar aims and background assumptions but different orientations, Trehub’s Retinoid model, which focuses largely on the neural functioning of the visual system, and Rudrauf et al’s Projective Consciousness Model, which draws largely on projective geometries to specify the requirements of organisms that need to navigate a three-dimensional world, and how these might be implemented in human information processing. Together, these models illustrate both converging and diverging approaches to understanding the role of projective processes in human consciousness.

Published: February 2019

ABSTRACT The present study aimed to determine heavy metal concentrations in the tree bark of the species Poincianella pluviosa in Volta Redonda municipality, Rio de Janeiro. Four sets of barks of eight trees with three replicates each from sectors 1 (W), 2 (S), 3 (E), and 4 (N) of the Volta Redonda center corresponding to the cardinal points were collected. The samples were digested in a nitroperchloric mixture and the lead (Pb), cadmium (Cd), nickel (Ni), copper (Cu), zinc (Zn), iron (Fe), and manganese (Mn) contents were determined by atomic absorption spectrophotometry. The cluster analysis (CA) formed 12 groups; among them, group 3 (G3) showed the presence of all seven elements in sector 1 and group 8 (G8) showed the presence of Pb, Zn, Fe, Ni, and Mn in sector 2. Kruskal-Wallis and Bonferroni tests showed that all elements presented statistically different values among the four sectors when compared with each other (p > 0.05). Sectors 1, 2, and 3 had the highest concentrations of heavy metals, which are directly associated with vehicle and railroad flow and iron and steel activities that are concentrated in these sectors. Bark can be used as an effective method for the monitoring of air pollution in urban areas.

The majority presented physical illness and there was an association between social (p<0.001) and psychological (p=0.001) damages in drowsy workers. Conclusion: workers with excessive daytime sleepiness were identified and it was evidenced an association between lack of sleep and impairment of the worker's health in a psychosocial context.
Planos diretores municipais e planos de gestão das águas: uma análise comparada das cidades de Lisboa/PT e Porto Alegre/BR
Authors: Young Juliana , Sedoura Francisco Manuel
Published: February 2019

Resumo A transformação do território está relacionada à ocupação do solo, o que reflete nos recursos hídricos. É necessário que os Planos Diretores Municipais (PDM) contemplem as diretrizes delineadas nos planos de água, levando à transformação sustentável do território e produzindo menos impacto nos rios. O objetivo deste trabalho foi analisar a interação entre os planos de água e solo. A inovação aqui apresentada foi o uso das Questões Significativas de Gestão da Água (QSiGA) como ferramenta para comparar os planos diretores das cidades de Lisboa, em Portugal, e de Porto Alegre, no Brasil, localizadas em diferentes realidades. Obteve-se o atendimento de 77,8% das QSiGA pelo PDM de Lisboa e 61,1% pelo de Porto Alegre. Ambas as cidades estão preocupadas com a qualidade e a quantidade de água, mas não observam plenamente as diretrizes nacionais. Acredita-se na relevância deste estudo para a materialização de um método de aferição dos PDM que possa ser usado por países com diferentes realidades. Conclui-se que, ao identificar que as diretrizes nacionais não foram totalmente cumpridas, são necessários estudos adicionais para se estabelecer uma metodologia que integre efetivamente planos de água com planos diretores.

Authors: KOTZE Lorete Maria da Silva , KOTZE Luiz Roberto , MORENO Isabela , NISIHARA Renato
Published: February 2019

ABSTRACT BACKGROUND: Up to 15% of other immune-mediated diseases (IMDs) can occur in patients with CD throughout their lives and are associated with multiple factors, including sex and sex hormone levels. Moreover, sex is associated with differences in clinical presentation, onset, progression, and outcomes of disorders. OBJECTIVE: To investigate the prevalence of IMDs at diagnosis in patients with celiac disease (CD) and their first-degree relatives and to compare the findings between female and male patients of different age. METHODS: A retrospective study including Brazilian patients with CD who visited the same doctor during January 2012 to January 2017 was performed. Demographic and medical history data were collected through self-administered questionnaires and medical charts of the patients. In total, 213 patients were examined at diagnosis: 52 males (mean age, 40.0 years) and 161 females (mean age, 41.4 years). The patients were divided into two groups according to sex and age. RESULTS: IMDs were observed in 60.2% of the female (97/161) and 42.3% of the male patients (22/52; P=0.22). However, the frequency of IMDs was significantly higher in females aged 51-60 years than in males with same age (P=0.0002). Dermatitis herpetiformis (DH) was significantly more prevalent in males (P=0.02), whereas atopy was more prevalent in females (P=0.02). IMDs observed in first-degree relatives were similar to those observed in patients (70.9%; P<0.001), with a higher number observed in female relatives. CONCLUSION: The frequency of IMDs in CD patients was similar in all age groups and both sexes, except women diagnosed with CD after 51 years of age presented with an increased frequency of IMDs compared with males. Dermatitis herpetiformis was more prevalent in males, whereas atopy was more prevalent in females. No difference was observed in the type of IMDs between the first-degree relatives of both sexes.

Published: February 2019

ABSTRACT BACKGROUND: Colorectal cancer is one of the major causes of death worldwide. Many studies have been done on the biology of its formation as well as its treatment in recent years. One of the factors involved in the formation or treatment of this malignancy can be attributed to the microbial flora in the intestine. OBJECTIVE: This study investigate the potential preventive effect of Lactobacillus acidophilus and Lactobacillus plantarum in patients with polyps or colorectal cancer (CRC). METHODS: A total of 77 samples were selected in the form of three groups including individuals suffering from CRC, polyps and healthy subjects. Genomic DNA of fecal specimens and standard strains were extracted and amplified employing primers targeting of the 16S rRNA gene for initial detection. Absolute Real Time PCR quantification was used to determine the copy of the bacterial expression per gram of feces. RESULTS: No significant difference were observed between age and gender in the mentioned groups (P=0.06). The average copy number of Lactobacillus acidophilus shows Significant difference between the healthy group and those with polyps (P<0.0001), the healthy group and those with colorectal cancer (P<0.0001), as well as those with polyps and the colorectal cancer patients (P<0.0001). CONCLUSION: These results may indicate that taking Lactobacillus acidophilus in people with a family history of CRC and people with polyps may be a way of preventing, treating or reducing the severity of CRC.
Performance of limestone calcined clay blended cement-based concrete against carbonation
Authors: Khan Mohammad S. H. , Nguyen Quang Dieu , Castel Arnaud
Published: February 2019

The aim of this work is to investigate the carbonation resistance of limestone and calcined clay blended cement-based concrete. Two limestone and calcined clay concretes with an average 28 d compressive strength of about 36 MPa were considered. Limestone and calcined clay (with a ratio of 2 : 1) were blended with a general purpose (GP) cement. The GP cement substitution rates considered were 30% and 45%.A low-grade calcined clay was used with about 50% amorphous phase. Accelerated and natural carbonation tests were performed. Mercury intrusion porosimetry and X-ray diffraction were carried out, to assist in the analysis of the experimental results. Results show that the early-age compressive strength is only marginally affected by the limestone and calcined clay substitution up to 45% and a significant refinement of the pore structure was observed compared to the reference GP cement concrete. The resistance of concrete against carbonation reduces with increase in the GP cement substitution rate. Overall, this study shows that a limestone and calcined clay blend used as a simple substitution for GP cement in concrete can provide adequate protection against carbonation-induced steel reinforcement corrosion if the ordinary Portland cement content in the mix is at least 60%.
Effect of MQL on roughness, white layer and microhardness in hard turning of AISI 52100
Authors: Pradeep Allu Venkat , Dumpala Lingaraju , Ramakrishna Shinagam
Published: February 2019

The influence of turning parameters on the surface integrity of the workpiece in hard turning of AISI 52100 steel using minimum quantity lubrication (MQL), was investigated in this work. The cutting parameters considered were cutting speed, feed, depth of cut and tool nose radius, at three levels each. Response surface methodology was employed to study the influence of factors on surface roughness, microhardness, topography, white layer thickness and elemental composition. From model analysis, the microhardness and surface roughness were best predicted by quadratic regression models, whereas white layer thickness was best evaluated by a linear model. The variance analysis revealed that surface roughness was significantly affected by nose radius (33·83%), followed by feed (32·5%). It was observed that surface defects were reduced with an increase in cutting speed. Microhardness was majorly affected by feed (36·64%), followed by nose radius (32·88%). The white layer thickness ranged from 4·3 to 15·9 μm for all experiments. White layer thickness was significantly influenced by nose radius (82·24%), cutting speed (9·78%) and feed (1·23%). Energy-dispersive X-ray spectroscopy analysis of the machined workpiece at a cutting speed of 150 m/min validated that oxidation was instigated and the weight percent of carbon was augmented in the base metal.

Published: February 2019

Biochar (BC) has been proposed as an alternative soil amendment in landfill cover. Its effects on soil hydraulic properties (e.g. soil water retention) have been explored to some extent, while its influence on landfill gas flow characteristics is not clear yet. The objective of this study is to investigate the water retention and gas permeability (kg) of BC-amended soil and its relationship with soil water content in unsaturated state. In total, three BC contents (0, 5 and 10%) were considered in clay–sand mixtures. Soil suction, water content and gas pressure were measured continuously using a new in-house developed apparatus. Test results show that the presence of BC increased soil water content and the increased amount was almost the same over a wide range of suction values (up to 3 MPa). kgincreased linearly with soil suction in semi-log scale, regardless of the BC content. The addition of 5 and 10% of BC could decrease kgby up to 50 and 65%, respectively, compared with that of the bare soil. kgdecreased with water content for both soil and BC -amended soils. Moreover, the decrease rate of kgwith water content became smaller when the BC percentage was higher.

The Effects of Asynchronous Computer Voice Conferencing on L2 Learners' Speaking Anxiety
Authors: Poza María Isabel Charle
Published: February 2019

This study investigated the influence of a computer voice conferencing environment (Wimba) on learners’ anxiety when speaking in a foreign language. Several instruments were used for data collection: A demographic survey, the Computer Anxiety Index (CAIN), the Foreign Language Classroom Anxiety Scale (FLCAS), the Wimba Anxiety Scale, student interviews, and a rubric developed for the evaluation of risk-taking. Results indicate that there is a strong potential for the reduction of anxiety associated with the Wimba environment. This was due to the elimination of the time pressure of the classroom and opportunity to edit student contributions. Increased risk-taking, in terms of the quantity and quality of the output produced by students, and reduced fear of negative evaluation were also found in the electronic environment. The conditions of the facility where the Wimba environment is accessed, i.e. a language laboratory, were found to hinder Wimba’s anxiety-reducing potential.

This paper reports on an empirical study in mobile language learning,with the purpose of exploring how mobile technology affects thelearning of a foreign language.Mobile devices possess fundamental properties, such as portability,individuality, interactivity and connectivity, that are essential tolanguage learning, in that they enhance exposure and noticing,promote interaction and calibrate corrective feedback.The mobile device adopted for this study is the iPad, which can fulfillthe functions of a computer with the additional plus of beinglightweight and therefore easily portable. It has a wide high-resolutiontouch screen, which enhances input as well as learners’ attention,making them focus on key language features and raising theirawareness. Furthermore, the iPad is compatible with the most recentapplications for the development of interactive skills.The author investigated the impact of iPad on a class of sixth gradersin their first year of learning Italian and compared their learning to anon-iPadded class over two years’ time, first in sixth grade and then inseventh grade. Results show that, thanks to mobile technology, theiPadded sixth graders generally progressed better than the noniPaddedsixth graders, but, remarkably, even better than the noniPaddedseventh graders in oral interactive tasks.
RESPONSES TO STRUCTURAL VIOLENCE: THE EVERYDAY WAYS IN WHICH QUEER AND TRANS MIGRANTS WITH PRECARIOUS STATUS RESPOND TO AND RESIST THE CANADIAN IMMIGRATION REGIME
Authors: Lee Edward Ou Jin
Published: February 2019

This article examines how the Canadian immigration regime socially organizes the everyday lives of queer and trans migrants with precarious status. Drawing from key findings from an institutional ethnographic study, this article maps out the disjuncture between the actual experiences of queer and trans migrants with precarious status and the ideological and textual production of precarious status by the Canadian state. Making explicit this disjuncture reveals how the Canadian immigration regime enacts structural violence upon queer and trans migrants. This article also engages with the response-based approach to violence in order to understand how queer and trans migrants actively respond to this violence. In doing so, this article highlights the ways in which queer and trans migrants respond and resist the structural violence integral to the Canadian state’s production of precarious status.
Qualidade e sustentabilidade: sistemas de certificação do café sob a ótica dos Pilares da Qualidade
Authors: Leme Paulo Henrique Montagnana Vicente , Pinto Cintia Loos
Published: February 2019

Qualidade e sustentabilidade são conceitos complexos, mas cada vez mais importantes no contexto da produção de alimentos. Neste cenário, os sistemas de certificações assumem papel importante de coordenação das diversas cadeias. Este trabalho utiliza a metodologia de análise dos pilares da qualidade proposta por Leme (2007) para analisar quatro certificações ligadas ao café: o Programa de Qualidade do Café (PQC), a certificação do Café do Cerrado, a certificação Rainforest Alliance e a certificação Utz Certified. O objetivo é unir os conceitos de certificação e qualidade sob um referencial teórico único, analisando como estas certificações abordam a qualidade em suas normas e diretrizes. Para isto, os pontos principais de cada programa de certificação foram analisados e sistematizados segundo o modelo proposto. O modelo dos pilares da qualidade demonstrou-se muito útil para sistematizar e analisar os objetos de estudo no que se refere aos principais aspectos ligados à certificação e qualidade no agronegócio café.

Wierny i rzetelny obraz instrumentów pochodnych w sprawozdaniu finansowym według modelu rachunkowości zabezpieczeń w dobie MSSF 9
Authors: Dunal Patryk , Andrzejewski Mariusz , Ożga Paweł
Published: February 2019

Zasady rachunkowości instrumentów pochodnych zawarte w Międzynarodowym Standardzie Rachunkowości 39 (MSR 39) były przedmiotem krytyki z uwagi na stopień skomplikowania i niedopasowanie do rzeczywistości biznesowej. Zastąpienie MSR 39 Międzynarodowym Standardem Sprawozdawczości Finansowej 9 (MSSF 9) miało z jednej strony uprościć zasady rachunkowości zabezpieczeń i przyczynić się do jej szerszego stosowania, a z drugiej wyeliminować niedoskonałości poprzedniego standardu i poprawić jakość informacji na temat instrumentów pochodnych, przekazywanej w sprawozdaniu finansowym. MSSF 9 wprowadził wiele zmian w zakresie rachunkowości instrumentów pochodnych i dlatego też zasadna wydaje się dyskusja na temat ich konsekwencji i wpływu na rzetelność i wiarygodność informacji przekazywanej otoczeniu. Jest to niezwykle istotne, gdyż z instrumentami pochodnymi wiąże się znaczne ryzyko – ich nieumiejętne stosowanie niejednokrotnie prowadziło do znacznych problemów finansowych lub upadłości przedsiębiorstw i instytucji finansowych. Celem niniejszego artykułu jest przedstawienie najważniejszych zmian w rachunkowości instrumentów pochodnych zaimplementowanych w MSSF 9 oraz analiza ich wpływu na walory informacyjne sprawozdań finansowych jednostek gospodarczych, tj. wierne i rzetelne odzwierciedlenie ekonomicznych efektów stosowania derywatów.
Inwestycje w złoto jako zabezpieczenie przed inflacją w wybranych krajach
Authors: Mamcarz Katarzyna
Published: February 2019

Złoto jest metalem szlachetnym, który pełni ważną funkcję w zarządzaniu aktywami. Celem artykułu jest ocena inwestycji w złoto jako aktywów zabezpieczających inwestorów przed inflacją w wybranych pięciu krajach (USA, Wielka Brytania, Szwajcaria, Japonia, Kanada) i strefie euro. Analizowane kraje są ważnymi inwestorami na rynku złota oraz jego producentami (USA, Kanada). Dla realizacji tego celu dokonano ilustracji graficznej zależności między nominalną ceną złota i ceną złota zabezpieczającą przed inflacją, a także zbudowano model liniowy, obrazujący elastyczność stopy zwrotu ze złota względem inflacji (parametr β). Modele dla poszczególnych krajów poddano także weryfikacji, uwzględniając współczynniki determinacji i błędy standardowe reszt oraz stosując statystykę Durbina‑Watsona (autokorelacja), test na normalność rozkładu reszt (Doornika‑Hansena), test White’a na heteroskedastyczność reszt oraz test na nieliniowość (kwadraty zmiennych). Badania przeprowadzono na podstawie publikowanych na koniec miesiąca danych na temat cen złota i indeksu ogólnego poziomu cen (Consumer Price Index), wyrażającego zmiany poziomu inflacji w latach 1990–2016. Badania dowiodły, że inflacja, abstrahując od nielicznych przypadków, miała niewielki wpływ na kształtowaniem się ceny złota w walutach narodowych poszczególnych krajów. Cena złota zabezpieczająca przed inflacją wykazała, z wyjątkiem Japonii, trend rosnący, mimo różnych wahań nominalnych cen złota. Inwestorzy mieli szansę osiągania stóp zwrotu przewyższających inflację, nabywając złoto w okresie, gdy jego cena nominalna kształtowała się poniżej fair value. Złoto okazało się doskonałym zabezpieczeniem przed inflacją dla inwestorów z Kanady, biorąc pod uwagę zarówno cały okres analizy, jak i okres hossy oraz bessy. Dotyczy to również USA w okresie bessy. Parametr β przyjmował poziom przekraczający jedność. Niepełne zabezpieczenie przed inflacją osiągnęli inwestorzy z USA (cały okres analizy, okres hossy) oraz Wielkiej Brytanii (okres hossy). W większości przypadków parametr β przyjmował jednak wartości ujemne, co oznacza, że cena złota nie podążała za zmianami inflacji, a inwestycje w złoto nie dawały zabezpieczenia przed nią. Otrzymane wyniki nie były zawsze istotne statystycznie przy przyjętych poziomach istotności.

Les plantations de palmiers phœnix ont une grande importance socio-économique et écologique en Tunisie. Actuellement, elles contiennent près de trois millions d'arbres, qui assurent d'importants approvisionnements en bois pour l'artisanat et l'industrie du meuble. Autrefois, le palmier dattier était également utilisé comme matériau de construction. Ses médiocres propriétés technologiques ont été améliorées par l'immersion dans l'eau salée naturelle des troncs de palmiers fraîchement coupés. C’était une pratique ancestrale dans la zone du Maghreb, mais elle a disparu maintenant, et les informations sur les différents paramètres impliqués dans ce type de processus sont rares. L’objectif de cette étude est d'évaluer les propriétés technologiques principales du bois de Phoenix dactylifera L. quand il est préservé dans l'eau salée. Des échantillons de bois prélevés dans le sud de la Tunisie sur deux cultivars communs de palmier dattier (Kentichi et Deglet Noor) âgés de 40 à 50 ans, non traités et conservés par salage dans le lac Chot Djérid, ont été utilisés pour ces expériences. Les densités, les propriétés mécaniques, la résistance à la putréfaction et aux termites et la composition chimique des échantillons de bois non traités (contrôle) et traités avec l’eau salée ont été déterminés. Les résultats ont montré une augmentation significative de la densité du bois de palmier séché à l'air après immersion dans l'eau salée. Le traitement avec l'eau salée a aussi amélioré le nodule de rupture du bois de palmier phœnix perpendiculairement et parallèlement aux fibres. Les deux, le bois non traité et le bois traité avec de l'eau salée, semblent être sensibles aux agressions de termites, mais le bois de palmier traité semble être plus toxique pour les termites. Les teneurs en extraits de lignine et de cellulose étaient légèrement plus abondantes dans les échantillons témoins, alors que les hémicelluloses étaient plus abondantes dans les échantillons traités. Les analyses minéralogiques ont permis également d'expliquer l'amélioration de la performance du bois de palmier après ce processus de préservation naturelle.

La connaissance du volume exploitable est une information essentielle tant pour la gestion que pour le contrôle de l’exploitation forestière. En Afrique centrale, l’estimation des volumes repose essentiellement sur l’utilisation de tarifs de cubage à une entrée, spécifique à chaque essence, et prédisant le volume exploitable à partir du diamètre de l’arbre. Or, récemment, de nombreux acteurs de la gestion forestière au Cameroun rapportent une inadéquation entre les volumes commerciaux estimés avec les tarifs de cubage imposés par l’administration et les volumes estimés à partir des mesures de la longueur et du diamètre des billes exploitées. Afin de vérifier la justesse des tarifs de cubage imposés par l’administration camerounaise, nous avons réalisé un échantillonnage destructif pour 12 essences jouant un rôle crucial dans le commerce du bois au Cameroun, et développé de nouveaux tarifs de cubage, qui ont été comparés avec les tarifs imposés par l’administration camerounaise et 52 autres tarifs de cubage disponibles dans la littérature. Dans quatre concessions forestières du Cameroun, représentatives des différentes conditions écologiques prévalant dans ce pays, 732 arbres ont été abattus et leur volume a été mesuré par la méthode des billons successifs. Des tarifs de cubage à une entrée, fonction uniquement du diamètre de référence, ont ensuite été ajustés par la méthode des moindres carrés généralisés. Notre étude confirme l’existence de biais entre les volumes mesurés et les volumes estimés en utilisant les tarifs de cubage imposés par l’administration camerounaise. En conséquence, de nouveaux tarifs de cubage et un abaque de correction sont proposés. Enfin, la majorité des tarifs de cubage testés présentaient un biais similaire qui résulte vraisemblablement d’une évolution de la ressource et des pratiques d’exploitation.

En zone tropicale, les services écosystémiques associés aux espèces agroforestières sont peu connus. Une enquête ethnobotanique a été conduite dans le bassin versant de Boura pour appréhender la perception des espèces agroforestières et leurs services écosystémiques. Des interviews semi-structurées et des observations directes ont été réalisées auprès de 214 chefs d'exploitation (CE) appartenant aux groupes ethniques Sissala, Dagara et Mossi. Les caractéristiques socio-économiques des CE, les espèces ligneuses conservées dans les champs et leurs services écosystémiques ont été recensés. L’importance des espèces a été déterminée selon la méthode de l’indice culturel d’importance (ICT). Des tests de comparaison des réponses et des modèles linéaires généralisés ont été réalisés à l’aide du logiciel R.3.3.2. Au total, 64 espèces ligneuses appartenant à 59 genres et 30 familles ont été recensées. Ces espèces fournissent aux communautés 17 services écosystémiques répartis en quatre catégories. Vitellaria paradoxa (ICT = 10,45) et Parkia biglobosa (ICT = 7,80) sont deux espèces agroforestières clés pourvoyeuses de services écosystémiques à l’ensemble des communautés. L’ordination non métrique (NMS) de la matrice d’occurrence des espèces agroforestières indique qu’en dépit des similitudes de connaissances ethnobotaniques les groupes ethniques Dagara et Sissala manifestent différentes préférences dans la conservation d’essences ligneuses spécifiques dans les champs. Le groupe ethnique, le genre, la taille du ménage, le niveau d’éducation et l’expérience du chef d’exploitation sont les principaux facteurs déterminant la perception et la conservation des espèces agroforestières. La sélection d’essences végétales pour les interventions agroforestières doit tenir compte des facteurs socio-économiques déterminant les préférences des communautés.

Química analítica básica: equilíbrios iônicos em solução aquosa
Authors: Andrade João Carlos de
Published: February 2019

Obedecendo à lei fundamental da natureza que diz: “um sistema físico ou químico sempre tende a provocar uma mudança irreversível de algum estado de não-equilíbrio inicial, para um estado de equilíbrio final”, as reações químicas podem ser definidas como processos em que diferentes substâncias interagem entre si, ocorrendo um rearranjo de átomos que acaba alterando completamente as características iniciais das substâncias envolvidas, tendendo a uma situação de equilíbrio. Neste artigo mostramse, concisamente, os aspectos cinéticos e termodinâmicos dos estados de equilíbrio em solução aquosa.
