The use of textbooks in Capeverdean secondary schools: The Relationship between Use, Evaluation and Adaptation of Textbooks

This study examines the relationship between teacher’s use of English textbooks and the way teachers evaluate and adapt them, looking at a particular context, the Capeverdean secondary schools, specifically in Praia. The referred relationship was analyzed through teachers’ responses about how they use, evaluate and adapt their textbooks. The results of the study revealed that, on the one hand, the way teachers use their textbooks influences the way they evaluate the same textbooks; on the other hand, the use of textbooks doesn’t necessarily influence the way teachers adapt them. Moreover, the findings revealed that, in general, due to some particular constraints the Capeverdean English teachers are using their textbooks as resources, in which several textbooks are used in combination with one another. Additionally, although teachers assume that they are doing their best, they still need more confidence concerning the way they use, evaluate and adapt available textbooks. Teachers’ confidence in the way they are using their textbooks can be reinforced by establishing an intensive teacher training module on materials evaluation and adaptation, taking into account that a textbook is one of the most important tools in the process of teaching and learning. I hope that the elements presented may lead to further studies on this matter, specifically regarding textbook evaluation and adaptation.

Individual and contextual effects aretested applying multilevel analysis. The results show that educational public policies(level of decentralization, degree of comprehensiveness and public spending) as well asthe students social environment (socioeconomic and cultural status) have a soundimpact on the opinions about the state of education.

Identifying the gap between need and intervention for alcohol use disorders in Europe.

AIMS: A literature review of existing research on the prevalence of alcohol use disorders (AUDs) and availability of alcohol interventions in Europe was conducted. The review also explored what is known about the gap between need and provision of alcohol interventions in Europe. METHODS: The review search strategy included: (i) descriptive studies of alcohol intervention systems in Europe; (ii) studies of alcohol service provision in Europe; and (iii) studies of prevalence of AUD and alcohol needs assessment in Europe. RESULTS: Europe has a relatively high level of alcohol consumption and the resulting disabilities are the highest in the world. Most research on implementation of alcohol interventions in Europe has been restricted to screening and brief interventions. Alcohol needs assessment methodology has been developed but has not been applied in comparative studies across countries in Europe. CONCLUSIONS: This review points to key gaps in knowledge related to alcohol interventions in Europe. There is a lack of comparative data on variations in alcohol treatment systems across European countries and there is also a lack of comparative data on the prevalence of alcohol use disorders across European countries and the relative gap between need and access to treatment. The forthcoming Alcohol Measures for Public Health Research Alliance (AMPHORA) research project work package on 'Early identification and treatment' aims to address these gaps.

The role of alliance in the relationship between therapist competence and outcome in brief psychodynamic psychotherapy.

Therapist competence is a key variable for psychotherapy research. Empirically, the relationship between competence and therapeutic outcome has shown contradictory results and needs to be clarified, especially with regard to possible variables influencing this relationship. A total of 78 outpatients were treated by 15 therapists in a very brief 4-session format, based on psychoanalytic theory. Data were analyzed by means of a nested design using hierarchical linear modeling. No direct link between therapist competence and outcome has been found, however, results corroborated the importance of alliance patterns as moderator in the relationship between therapist competence and outcome. Only in dyads with alliance change over the course of treatment was it clear that competence is positively related to outcome. These findings are discussed with regard to the importance for outcome of therapist competence and alliance construction processes.

The role of fungi in the precipitation of calcite : relationships between fungal filaments, nanofibres, and needle fibre calcite

RésuméLes champignons sont impliqués dans les cycles biogéochimiques de différentes manières. En particulier, ils sont reconnus en tant qu'acteurs clés dans la dégradation de la matière organique, comme fournisseurs d'éléments nutritifs via l'altération des minéraux mais aussi comme grands producteurs d'acide oxalique et de complexes oxalo-métalliques. Toutefois, peu de choses sont connues quant à leur contribution à la genèse d'autres types de minéraux, tel que le carbonate de calcium (CaCO3). Le CaCO3 est un minéral ubiquiste dans de nombreux écosystèmes et il joue un rôle essentiel dans les cycles biogéochimiques du carbone (C) et du calcium (Ca). Le CaCO3 peut être d'origine physico-chimique ou biogénique et de nombreux organismes sont connus pour contrôler ou induire sa biominéralisation. Les champignons ont souvent été soupçonnés d'être impliqué dans ce processus, cependant il existe très peu d'informations pour étayer cette hypothèse.Cette thèse a eu pour but l'étude de cet aspect négligé de l'impact des champignons dans les cycles biogéochimiques, par l'exploration de leur implication potentielle dans la formation d'un type particulier de CaCO3 secondaires observés dans les sols et dans les grottes des environnements calcaires. Dans les grottes, ces dépôts sont appelés moonmilk, alors que dans les sols on les appelle calcite en aiguilles. Cependant ces deux descriptions correspondent en fait au même assemblage microscopique de deux habitus particulier de la calcite: la calcite en aiguilles (au sens strict du terme cette fois-ci) et les nanofibres. Ces deux éléments sont des habitus aciculaires de la calcite, mais présentent des dimensions différentes. Leur origine, physico-chimique ou biologique, est l'objet de débats intenses depuis plusieurs années déjà.L'observation d'échantillons environnementaux avec des techniques de microscopie (microscopie électronique et micromorphologie), ainsi que de la microanalyse EDX, ont démontré plusieurs relations intéressantes entre la calcite en aiguilles, les nanofibres et des éléments organiques. Premièrement, il est montré que les nanofibres peuvent être organiques ou minérales. Deuxièmement, la calcite en aiguilles et les nanofibres présentent de fortes analogies avec des structures hyphales, ce qui permet de confirmer l'hypothèse de leur origine fongique. En outre, des expériences en laboratoire ont confirmé l'origine fongique des nanofibres, par des digestions enzymatiques d'hyphes fongiques. En effet, des structures à base de nanofibres, similaires à celles observées dans des échantillons naturels, ont pu être produites par cette approche. Finalement, des enrichissements en calcium ont été mesurés dans les parois des hyphes et dans des inclusions intrahyphales provenant d'échantillons naturels de rhizomorphes. Ces résultats suggèrent une implication de la séquestration de calcium dans la formation de la calcite en aiguilles et/ou des nanofibres.Plusieurs aspects restent à élucider, en particulier la compréhension des processus physiologiques impliqués dans la nucléation de calcite dans les hyphes fongiques. Cependant, les résultats obtenus dans cette thèse ont permis de confirmer l'implication des champignons dans la formation de la calcite en aiguilles et des nanofibres. Ces découvertes sont d'une grande importance dans les cycles biogéochimiques puisqu'ils apportent de nouveaux éléments dans le cycle couplé C-Ca. Classiquement, les champignons sont considérés comme étant impliqués principalement dans la minéralisation de la matière organique et dans l'altération minérale. Cette étude démontre que les champignons doivent aussi être pris en compte en tant qu'agents majeurs de la genèse de minéraux, en particulier de CaCO3. Ceci représente une toute nouvelle perspective en géomycologie quant à la participation des champignons au cycle biologique du C. En effet, la présence de ces précipitations de CaCO3 secondaires représente un court-circuit dans le cycle biologique du C puisque du C inorganique du sol se retrouve piégé dans de la calcite plutôt que d'être retourné dans l'atmosphère.AbstractFungi are known to be involved in biogeochemical cycles in numerous ways. In particular, they are recognized as key players in organic matter recycling, as nutrient suppliers via mineral weathering, as well as large producers of oxalic acid and metal-oxalate. However, little is known about their contribution to the genesis of other types of minerals such as calcium carbonate (CaCO3). Yet, CaC03 are ubiquitous minerals in many ecosystems and play an essential role in the biogeochemical cycles of both carbon (C) and calcium (Ca). CaC03 may be physicochemical or biogenic in origin and numerous organisms have been recognized to control or induce calcite biomineralization. While fungi have often been suspected to be involved in this process, only scarce information support this hypothesis.This Ph.D. thesis aims at investigating this disregarded aspect of fungal impact on biogeochemical cycles by exploring their possible implication in the formation of a particular type of secondary CaC03 deposit ubiquitously observed in soils and caves from calcareous environments. In caves, these deposits are known as moonmilk, whereas in soils, they are known as Needle Fibre Calcite (NFC - sensu lato). However, they both correspond to the same microscopic assemblage of two distinct and unusual habits of calcite: NFC {sensu stricto) and nanofibres. Both features are acicular habits of calcite displaying different dimensions. Whether these habits are physicochemical or biogenic in origin has been under discussion for a long time.Observations of natural samples using microscopic techniques (electron microscopy and micromorphology) and EDX microanalyses have demonstrated several interesting relationships between NFC, nanofibres, and organic features. First, it has shown that nanofibres can be either organic or minera! in nature. Second, both nanofibres and NFC display strong structural analogies with fungal hyphal features, supporting their fungal origin. Furthermore, laboratory experiments have confirmed the fungal origin of nanofibres through an enzymatic digestion of fungal hyphae. Indeed, structures made of nanofibres with similar features as those observed in natural samples have been produced. Finally, calcium enrichments have been measured in both cell walls and intrahyphal inclusions of hyphae from rhizomorphs sampled in the natural environment. These results point out an involvement of calcium sequestration in nanofibres and/or NFC genesis.Several aspects need further investigation, in particular the understanding of the physiological processes involved in hyphal calcite nucleation. However, the results obtained during this study have allowed the confirmation of the implication of fungi in the formation of both NFC and nanofibres. These findings are of great importance regarding global biogeochemical cycles as they bring new insights into the coupled C and Ca cycles. Conventionally, fungi are considered to be involved in organic matter mineralization and mineral weathering. In this study, we demonstrate that they must also be considered as major agents in mineral genesis, in particular CaC03. This is a completely new perspective in geomycology regarding the role of fungi in the short-term (or biological) C cycle. Indeed, the presence of these secondary CaC03 precipitations represents a bypass in the short- term carbon cycle, as soil inorganic C is not readily returned to the atmosphere.

PEASANT AND SCIENTIFIC KNOWLEDGE ON PLANOSOLS AS A SOURCE OF MATERIALS IN THE MAKING OF NON-INDUSTRIAL POTTERY

Ethnopedological studies have mainly focused on agricultural land uses and associated practices. Nevertheless, peasant and indigenous populations use soil and land resources for a number of additional purposes, including pottery. In the present study, we describe and analyze folk knowledge related to the use of soils in non-industrial pottery making by peasant potters, in the municipality of Altinho, Pernambuco State, semiarid region at Brazil. Ethnoscientific techniques were used to record local knowledge, with an emphasis on describing the soil materials recognized by the potters, the properties they used to identify those soil materials, and the criteria employed by them to differentiate and relate such materials. The potters recognized three categories of soil materials: “terra” (earth), “barro” (clay) and, “piçarro” (soft rock). The multi-layered arrangement of these materials within the soil profiles was similar to the arrangement of the soil horizon described by formal pedologists. “Barro vermelho” (red clay) was considered by potters as the principal ceramic resource. The potters followed morphological and utilitarian criteria in distinguishing the different soil materials. Soils from all of these sites were sodium-affected Alfisols and correspond to Typic Albaqualf and Typic Natraqualf in the Soil Taxonomy (Soil Survey Staff, 2010).

Unravelling the interaction between tectonic and sedimentary processes during lithospheric thinning in the Alpine Tethys margins

The discovery of exhumed continental mantle and hyper-extended crust in present-day magma-poor rifted margins is at the origin of a paradigm shift within the research field of deep-water rifted margins. It opened new questions about the strain history of rifted margins and the nature and composition of sedimentary, crustal and mantle rocks in rifted margins. Thanks to the benefit of more than one century of work in the Alps and access to world-class outcrops preserving the primary relationships between sediments and crustal and mantle rocks from the fossil Alpine Tethys margins, it is possible to link the subsidence history and syn-rift sedimentary evolution with the strain distribution observed in the crust and mantle rocks exposed in the distal rifted margins. In this paper, we will focus on the transition from early to late rifting that is associated with considerable crustal thinning and a reorganization of the rift system. Crustal thinning is at the origin of a major change in the style of deformation from high-angle to low-angle normal faulting which controls basin-architecture, sedimentary sources and processes and the nature of basement rocks exhumed along the detachment faults in the distal margin. Stratigraphic and isotopic ages indicate that this major change occurred in late Sinemurian time, involving a shift of the syn-rift sedimentation toward the distal domain associated with a major reorganization of the crustal structure with exhumation of lower and middle crust. These changes may be triggered by mantle processes, as indicated by the infiltration of MOR-type magmas in the lithospheric mantle, and the uplift of the Brianconnais domain. Thinning and exhumation of the crust and lithosphere also resulted in the creation of new paleogeographic domains, the Proto Valais and Liguria-Piemonte domains. These basins show a complex, 3D temporal and spatial evolution that might have evolved, at least in the case of the Liguria-Piemonte basin, in the formation of an embryonic oceanic crust. The re-interpretation of the rift evolution and the architecture of the distal rifted margins in the Alps have important implications for the understanding of rifted margins worldwide, but also for the paleogeographic reconstruction of the Alpine domain and its subsequent Alpine compressional overprint.

Effects of crop and weed densities on the interactions between barley and Lolium rigidum in several Mediterranean locations

The effects of both barley and Lolium rigidum densities on weed growth and spike production and on crop yield were examined in five field experiments carried out in the Mediterranean drylands of Spain and Western Australia. The aim was to check the consistency of the competitiveness of the crop in different environmental and management conditions. L. rigidum reduced barley yields in most of the experiments (between 0 and 85%), the number of ears per m2 being the most affected. It was found that increasing the barley seeding rate did not reduce the crop losses but did limit weed biomass (between 5 and 61%) and spike production (between 24 and 85%). The variability observed in crop yield losses between sites and seasons was related to rainfall at the beginning of the season. The most sensitive component of yield to weed competition was the number of ears per plant.

Between Cratylism and Positivism: the Old Poem and What Alice Found There

En aquest article em referiré molt sumàriament a la fi lologia del dinou, mirant de relacionar-la amb tot el joc de paraules en Lewis Carrol, per tal d'establir-hi una trama correcta de (dis)continuïtats. El meu objectiu és considerar el Jabberwocky de Humpty Dumpty en el context de la feina i les descobertes de la moderna fi lologia. F. A. Wolf i J. Grimm condensen bona cosa dels experiments radicals i les troballes que tingueren lloc en aquells moments, que podríem contrastar amb les aventures textuals d'Alícia a l'altra banda de l'espill. Els llibres de l'altra banda necessiten intèrprets i cerquen la versió correcta, original, de la mateixa manera que la interpretació dels mots depèn d'un mètode fi able. Segurament Lewis Carroll com a jove fi lòleg era capaç de jugar bé amb aquelles troballes, entre un món que s'acabava i un altre que començava.
