The Three Horsemen of Growth: Plague, War and Urbanization in Early Modern Europe

How did Europe overtake China? We construct a simple Malthusian model with two sectors, and use it to explain how European per capita incomes and urbanization rates could surge ahead of Chinese ones. That living standards could exceed subsistence levels at all in a Malthusian setting should be surprising. Rising fertility and falling mortality ought to have reversed any gains. We show that productivity growth in Europe can only explain a small fraction of rising living standards. Population dynamics - changes of the birth and death schedules - were far more important drivers of the longrun Malthusian equilibrium. The Black Death raised wages substantially, creating important knock-on effects. Because of Engel's Law, demand for urban products increased, raising urban wages and attracting migrants from rural areas. European cities were unhealthy, especially compared to Far Eastern ones. Urbanization pushed up aggregate death rates. This effect was reinforced by more frequent wars (fed by city wealth) and disease spread by trade. Thus, higher wages themselves reduced population pressure. Without technological change, our model can account for the sharp rise in European urbanization as well as permanently higher per capita incomes. We complement our calibration exercise with a detailed analysis of intra-European growth in the early modern period. Using a panel of European states in the period 1300-1700, we show that war frequency can explain a good share of the divergent fortunes within Europe.

Stakeholder Activism, Managerial Entrenchment, and the Congruence of Interests between Shareholders and Stakeholders

We argue that when stakeholder protection is left to the voluntary initiative of managers, concessions to social activists and pressure groups can turn into a self-entrenchment strategy for incumbent CEOs. Stakeholders other than shareholders thus benefit from corporate governance rules putting managers under a tough replacement threat. We show that a minimal amount of formal stakeholder protection, or the introduction of explicit covenants protecting stakeholder rights in the firm charter, may deprive CEOs of the alliance with powerful social activists, thus increasing managerial turnover and shareholder value. These results rationalize a recent trend whereby well-known social activists like Friends of the Earth and active shareholders like CalPERS are showing a growing support for each other s agendas.

Mediastinal lymph node clearance after docetaxel-cisplatin neoadjuvant chemotherapy is prognostic of survival in patients with stage IIIA pN2 non-small-cell lung cancer: a multicenter phase II trial.

PURPOSE: A multicenter, phase II trial investigated the efficacy and toxicity of neoadjuvant docetaxel-cisplatin in locally advanced non-small-cell lung cancer (NSCLC) and examined prognostic factors for patients not benefiting from surgery. PATIENTS AND METHODS: Ninety patients with previously untreated, potentially operable stage IIIA (mediastinoscopically pN2) NSCLC received three cycles of docetaxel 85 mg/m2 day 1 plus cisplatin 40 mg/m2 days 1 and 2, with subsequent surgical resection. RESULTS: Administered dose-intensities were docetaxel 85 mg/m2/3 weeks (range, 53 to 96) and cisplatin 95 mg/m2/3 weeks (range, 0 to 104). The 265 cycles were well tolerated, and the overall response rate was 66% (95% confidence interval [CI], 55% to 75%). Seventy-five patients underwent tumor resection with positive resection margin and involvement of the uppermost mediastinal lymph node in 16% and 35% of patients, respectively (perioperative mortality, 3%; morbidity, 17%). Pathologic complete response occurred in 19% of patients with tumor resection. In patients with tumor resection, downstaging to N0-1 at surgery was prognostic and significantly prolonged event-free survival (EFS) and overall survival (OS; P =.0001). At median follow-up of 32 months, the median EFS and OS were 14.8 months (range, 2.4 to 53.4) and 33 months (range, 2.4 to 53.4), respectively. Local relapse occurred in 27% of patients with tumor resection, with distant metastases in 37%. Multivariate analyses identified mediastinal clearance (hazard ratio, 0.22; P =.0003) and complete resection (hazard ratio, 0.26; P =.0006) as strongly prognostic for increased survival. CONCLUSION: Neoadjuvant docetaxel-cisplatin is effective and tolerable in stage IIIA pN2 NSCLC. Resection is recommended only for patients with mediastinal downstaging after chemotherapy.

Development of Implantable Flow-Through Left Ventricular Pressure Telemetric Transmitter for small Rodent Animals

Objective: Although 24-hour arterial blood pressure can be monitored in a free-moving animal using pressure telemetric transmitter mostly from Data Science International (DSI), accurate monitoring of 24-hour mouse left ventricular pressure (LVP) is not available because of its insufficient frequency response to a high frequency signal such as the maximum derivative of mouse LVP (LVdP/dtmax and LVdP/dtmin). The aim of the study was to develop a tiny implantable flow-through LVP telemetric transmitter for small rodent animals, which can be potentially adapted for human 24 hour BP and LVP accurate monitoring. Design and Method: The mouse LVP telemetric transmitter (Diameter: _12 mm, _0.4 g) was assembled by a pressure sensor, a passive RF telemetry chip, and to a 1.2F Polyurethane (PU) catheter tip. The device was developed in two configurations and compared with existing DSI system: (a) prototype-I: a new flow-through pressure sensor with wire link and (b) prototype-II: prototype-I plus a telemetry chip and its receiver. All the devices were applied in C57BL/6J mice. Data are mean_SEM. Results: A high frequency response (>100 Hz) PU heparin saline-filled catheter was inserted into mouse left ventricle via right carotid artery and implanted, LV systolic pressure (LVSP), LVdP/dtmax, and LVdP/dtmin were recorded on day2, 3, 4, 5, and 7 in conscious mice. The hemodynamic values were consistent and comparable (139_4 mmHg, 16634_319, - 12283_184 mmHg/s, n¼5) to one recorded by a validated Pebax03 catheter (138_2mmHg, 16045_443 and -12112_357 mmHg/s, n¼9). Similar LV hemodynamic values were obtained with Prototype-I. The same LVP waveforms were synchronically recorded by Notocord wire and Senimed wireless software through prototype-II in anesthetized mice. Conclusion: An implantable flow-through LVP transmitter (prototype-I) is generated for LVP accurate assessment in conscious mice. The prototype-II needs a further improvement on data transmission bandwidth and signal coupling distance to its receiver for accurate monitoring of LVP in a freemoving mouse.

Projection Par La Microsimulation de La Population Active Cap-Vert (2000-2025)

À l‟aide des microdonnées du recensement de 2000 et des données administratives sur l‟éducation et en s‟appuyant sur : 1) les scénarios concernant l‟évolution démographique, d‟éducation et d‟activité économique et 2) un modèle de microsimulation, on a projeté pour la période 2000 à 2025, certaines caractéristiques et comportements démographiques et socio-économiques de la population du Cap-Vert, notamment ceux liés à l‟évolution du statut d‟activité. Selon le scénario le plus plausible, à l‟horizon 2025, le pays se trouvera à l‟étape avancée de la seconde phase de sa transition démographique. Sa population continuerait de croître en raison de sa structure par âge relativement jeune. Bien que le solde migratoire tende à être nul et que la mortalité tende à se stabiliser (près de 5 à 7 décès pour 1 000 habitants par an), cette croissance sera à un rythme moins rapide (d‟environ 1,8 % par an) que celui de la décennie 1990-2000, et ce, malgré le déclin de la fécondité. De 2000 à 2025, le pays pourrait connaître également une augmentation des personnes âgées de 15 à 24 ans, variant de 26 % à 29 % selon les scénarios envisagés, soit ceux et celles qui entreront sur le marché du travail au cours de la période. Le nombre de ces jeunes n‟ayant pas obtenu un diplôme d‟études secondaire, en 2025, pourrait augmenter, selon les scénarios envisagés, variant de 30 % à 44 % de plus qu‟en 2000. Le nombre de personnes de ce groupe d‟âge ayant obtenu un diplôme d‟études secondaires ou plus, le pays pourrait voir leur nombre à décupler de 11 fois à 13 fois à la à l‟horizon 2025.

STRATEGIES TO SURPASS THE VULNERABILITY OF THE SMALL ISLAND STATES WITH FEW RESOURCES: THE CASE OF CAPE VERDE

The problem of small Island Developing States (SIDS) is quite recent, end of the 80s and 90s, still looking for a theoretical consolidation. SIDS, as small states in development, formed by one or several islands geographically dispersed, present reduced population, market, territory, natural resources, including drinkable water, and, in great number of the cases, low level of economic activity, factors that together, hinder the gathering of scale economies. To these diseconomies they come to join the more elevated costs in transports and communications which, allies to lower productivities, to a smaller quality and diversification of its productions, which difficult its integration in the world economy. In some SIDS these factors are not dissociating of the few investments in infrastructures, in the formation of human resources and in productive investments, just as it happens in most of the developing countries. In ecological terms, many of them with shortage of natural resources, but integrating important ecosystems in national and world terms, but with great fragility relatively to the pollution action, of excessive fishing, of uncontrolled development of tourism, factors that, conjugated and associated to the stove effect, condition the climate and the slope of the medium level of the sea water and therefore could put in cause the own survival of some of them. The drive to the awareness of the international community towards its problems summed up with the accomplishment by the United Nations in the Barbados’s Conference, 1994 where the right to the development was emphasized, through the going up the appropriate strategies and the Programme of Action for the Sustainable Development of the SIDS. The orientation of the regional and international cooperation in that sense, sharing technology (namely clean technology and control and administration environmental technology), information and creation of capacity-building, supplying means, including financial resources, creating non discriminatory and just trade rules, it would drive to the establishment of a world system economically more equal, in which the production, the consumption, the pollution levels, the demographic politics were guided towards the sustainability. It constituted an important step for the recognition for the international community on the specificities of those states and it allowed the definition of a group of norms and politics to implement at the national, regional and international level and it was important that they continued in the sense of the sustainable development. But this Conference had in its origin previous summits: the Summit of Rio de Janeiro about Environment and Development, accomplished in 1992, which left an important document - the Agenda 21, in the Conference of Stockholm at 1972 and even in the Conference of Ramsar, 1971 about “Wetlands.” CENTRO DE ESTUDOS AFRICANOS Occasional Papers © CEA - Centro de Estudos Africanos 4 Later, the Valletta Declaration, Malta, 1998, the Forum of Small States, 2002, get the international community's attention for the problems of SIDS again, in the sense that they act to increase its resilience. If the definition of “vulnerability” was the inability of the countries to resist economical, ecological and socially to the external shocks and “resilience” as the potential for them to absorb and minimize the impact of those shocks, presenting a structure that allows them to be little affected by them, a part of the available studies, dated of the 90s, indicate that the SIDS are more vulnerable than the other developing countries. The vulnerability of SIDS results from the fact the they present an assemblage of characteristics that turns them less capable of resisting or they advance strategies that allow a larger resilience to the external shocks, either anthropogenic (economical, financial, environmental) or even natural, connected with the vicissitudes of the nature. If these vulnerability factors were grouped with the expansion of the economic capitalist system at world level, the economic and financial globalisation, the incessant search of growing profits on the part of the multinational enterprises, the technological accelerated evolution drives to a situation of disfavour of the more poor. The creation of the resilience to the external shocks, to the process of globalisation, demands from SIDS and of many other developing countries the endogen definition of strategies and solid but flexible programs of integrated development. These must be assumed by the instituted power, but also by the other stakeholders, including companies and organizations of the civil society and for the population in general. But that demands strong investment in the formation of human resources, in infrastructures, in investigation centres; it demands the creation capacity not only to produce, but also to produce differently and do international marketing. It demands institutional capacity. Cape Verde is on its way to this stage.

Report to Government Oversight Committee Regrading Soil and Water Conservation Districts Competition with Small Business, 2006

At the request of the Government Oversight Committee, the Ombudsman gathered information regarding competition by county Soil and Water Conservation Districts (SWCD) with small business through the sale of products and services. The goal of the Ombudsman’s review was to assist the Government Oversight Committee (Committee) in gaining an objective understanding of the issues so the Committee can ascertain whether there is a problem that requires legislation this legislative session. The Ombudsman focused on gathering specific information from four SWCD offices in central Iowa; Dallas, Greene, Guthrie and Jasper. These offices were specifically identified in documentation presented to the Government Oversight Committee by affected small business owners (contractors), Jon Judson of Diversity Farms and Dan Brouse of Iowa Restorations. However, with 100 SWCDs in Iowa,1 each with their own elected commissioners and each with different practices, priorities and fundraising activities, what the Ombudsman learned about these four counties may not be applicable to all the SWCDs in Iowa. The Ombudsman assigned the case to the Assistant Citizens’ Aide/Ombudsman for Small Business, Kristie Hirschman. For reference purposes in this report, actions taken by Ms. Hirschman will be ascribed to the Ombudsman.

Le Créole du Cap-Vert Étude Grammaticale Descriptive et Contrastive

Cette étude linguistique porte sur les parlers de Santiago et de São Vicente, les deux variétés les plus représentatives du créole du Cap-Vert. Elle traite aussi bien des niveaux phonétique et phonologique que morphologique et syntaxique. Une approche contrastive inclut également la langue portugaise, d’où le créole capverdien tire l’essentiel de son origine. Elle s’interroge sur l’autonomisation du créole par rapport à sa langue source et pose des hypothèses sur les aspects socio-historiques qui auraient influencé son auto-régulation structurale. L’ouvrage s’adresse aux étudiants et chercheurs capverdiens ainsi qu’aux chercheurs spécialistes de la créolistique.

RsmY, a small regulatory RNA, is required in concert with RsmZ for GacA-dependent expression of biocontrol traits in Pseudomonas fluorescens CHA0.

In the plant-beneficial soil bacterium and biocontrol model organism Pseudomonas fluorescens CHA0, the GacS/GacA two-component system upregulates the production of biocontrol factors, i.e. antifungal secondary metabolites and extracellular enzymes, under conditions of slow, non-exponential growth. When activated, the GacS/GacA system promotes the transcription of a small regulatory RNA (RsmZ), which sequesters the small RNA-binding protein RsmA, a translational regulator of genes involved in biocontrol. The gene for a second GacA-regulated small RNA (RsmY) was detected in silico in various pseudomonads, and was cloned from strain CHA0. RsmY, like RsmZ, contains several characteristic GGA motifs. The rsmY gene was expressed in strain CHA0 as a 118 nt transcript which was most abundant in stationary phase, as revealed by Northern blot and transcriptional fusion analysis. Transcription of rsmY was enhanced by the addition of the strain's own supernatant extract containing a quorum-sensing signal and was abolished in gacS or gacA mutants. An rsmA mutation led to reduced rsmY expression, via a gacA-independent mechanism. Overexpression of rsmY restored the expression of target genes (hcnA, aprA) to gacS or gacA mutants. Whereas mutants deleted for either the rsmY or the rsmZ structural gene were not significantly altered in the synthesis of extracellular products (hydrogen cyanide, 2,4-diacetylphloroglucinol, exoprotease), an rsmY rsmZ double mutant was strongly impaired in this production and in its biocontrol properties in a cucumber-Pythium ultimum microcosm. Mobility shift assays demonstrated that multiple molecules of RsmA bound specifically to RsmY and RsmZ RNAs. In conclusion, two small, untranslated RNAs, RsmY and RsmZ, are key factors that relieve RsmA-mediated regulation of secondary metabolism and biocontrol traits in the GacS/GacA cascade of strain CHA0.

Alteration of glucose metabolism in cultured astrocytes after AQP9-small interference RNA application.

Aquaglyceroporin-9 (AQP9) facilitates diffusion of water and energy substrates such as glycerol and monocarboxylates. AQP9 is present in plasma membrane and mitochondria of astrocytes and catecholaminergic neurons, suggesting that it plays a role in the energetic status of these cells. Using specific small interference RNA directed against AQP9 in astrocyte cultures, we showed that glycerol uptake is decreased which is associated with an increase in glucose uptake and oxidative metabolism. Our results not only confirm the presence of AQP9 in astrocytes but also suggest that changes in AQP9 expression alter glial energy metabolism.

Predicted effects of small decreases in energy expenditure on weight gain in adult women.

Small daily positive energy imbalances of 200 to 800 kJ (about 50 to 200 kcal) due to reduced resting energy expenditure (REE), reduced diet-induced thermogenesis, or physical inactivity are believed to predispose to obesity. However, estimates of the magnitude of the weight gain often fail to account for concurrent changes in body composition and increases in maintenance energy requirements as weight increases and energy equilibrium is re-established. Using previously reported data on body composition and REE in women and the energy cost of tissue deposition, we used mathematical models to predict the theoretical effect of a persistent reduction in energy expenditure on long-term weight gain, assuming no adaptation in energy intake. The analyses indicate the following effects of a reduced level of energy expenditure in lean and obese women: (i) REE rises more slowly with increasing degrees of obesity due to a declining proportion of the more metabolically active fat-free mass; so, for the same positive energy balance, a significantly greater weight gain is expected for obese than for lean women before energy equilibrium is re-established; (ii) due to the greater energy density of adipose tissue, the time course of weight gain to achieve energy balance is longer for obese subjects: in general, this is approximately five years for lean and ten years for obese women; (iii) the magnitude of weight gain of lean women in response to a reduced energy expenditure of 200 to 800 kJ/day is only about 3 to 15 kg, amounts insufficient to explain severe obesity.

Érosion des sols au Cap Vert : étude des processus et quantification à l’échelle de trois bassins versants de l’île de Santiago

Erosão dos solos em Cabo Verde: estudo dos processos e quantificação à escala de três bacias hidrográficas O arquipélago de Cabo Verde é constituído por 10 ilhas vulcânicas pertence à zona do Sahel que se estende do Atlântico ao Mar Vermelho. Desde então, várias décadas, Cabo Verde é afectado pela desertificação causada principalmente pela recessão climatica e a erosão do solo. Esses fatores, aliados à alta pressão humana sobre os recursos, a topografia acidentada e chuvas tropicais por vezes torrenciais, causam sérios danos aos solos. No entanto, desde sua independência em 1975, o Governo realizou um amplo programa de arborização, recuperação de áreas degradadas e a correcção dos leitos das ribeiras. No entanto, a investigação, muito pouco foi realizada para avaliar as acções de protecção e conservação do solo e da água. Portanto, não há dados sobre o problema da degradação das terras nem balanços. Como parte deste trabalho, foram estudados vários factores que controlam a erosão do solo pela água. Especificamente, buscou-se diferenciar os efeitos das actividades humanas, incluindo a agricultura, os factores climáticos, como chuva e geração de escoamento. Também estabeleceu os primeiros balanços das exportações de matérias em suspensão e em solução no contexto do arquipélago de Cabo Verde. O estudo foi realizado em três bacias hidrográficas da ilha de Santiago, Cabo Verde. Estas três bacias hidrográficas (Longueira, Grande e Godim) estão localizadas na parte central da ilha de Santiago e representam os diversos tipos de uso da terra e as diferentes zonas bioclimaticas da ilha. Existe um gradiente climático entre as três bacias hidrográficas. Na verdade, Longueira que abrange uma área de 4,18 km2, tem um declive médio de 47 %, uma zona florestada de 69% e uma área agrícola de 17 %. Grande com uma área de 1,87 km2, é localizada numa zona sub humida com um declive médio de 50%, é essencialmente agrícola. Godim, com uma área de 2,0 km2, é localizado numa zona semi-árida com um declive médio de 32%, é particularmente uma zona agricola. Para estes três bacias hidrográficas, as cheias foram medidas e amostradas de 2004 a 2009. A bacia de Longueira teve um maior acompanhamento, nomeadamente em termos de amostragem e monitoramento dos escoamentos. Em cada amostra foram feitas a determinação da concentração de matérias em suspensão e a análise dos principais elementos quimicos. Os resultados mostram que a erosão mecânica nas três bacias hidrográficas é caracterizada por uma forte variabilidade espacial e temporal. Durante o período de 2005-2009, o balanço anual média para as bacias hidrográficas de Longueira, Grande e Godim é: 4266, 157 e 10,1 t.km2.an-1, respectivamente. A estação das chuvas de 2006 foi a mais erosiva para as três bacias, particularmente em Longueira, com 2 cheias excepcionais, que têm gerado uma concentração média de sólidos em suspensão superior a 100 g / l. Porém, as estações do ano de 2005 e 2008 foram de uma forma geral menos erosivas porque as concentrações médias não inferiores a 20 g / l. Além disso, não houve cheias para as temporadas 2005 e 2007 para a bacia do Godim. Na bacia de Longueira, o estudo dos fenómenos de histerese na caracterização das cheias mostrou que a evolução temporal das exportações de sólidos em suspensão durante a temporada é fortemente influenciada pelas atividades agrícolas. Na verdade, a primeira cheia causou uma exportação maciça de sedimento disponível e localizado no leito da ribeira. Assim, a segunda cheia exportou menos sedimentos. Um mês após as primeiras chuvas, a prática da monda que reduz a densidade da cobertura vegetal e destructura a camada superficial do solo, gerou uma grande quantidade de sedimento que novamente permitiu uma exportação muito forte de sedimentos durante a terceira forte cheia. Os resultados da erosão química na bacia de Longueira indicam que a taxa de erosão é de 45 t.km2.an-1 com uma forte variabilidade temporal. Na verdade, as temporadas de 2006 e 2007 são as mais erosivas, enquanto 2005 teve uma exportação de matérias disolvidas baixa. A utilização do modelo EMMA (End- Members Mixing Analysis) mostra que os escoamentos hipodermico e profundo, alimentandos os fluxos de elementos dissolvidos são os principais factores da erosão química. É mostrado que esses fluxos causam mais de 90% dos fluxos de erosão química. O escoamento superficial, que contribui com cerca de 70% na formação das cheias, é o maior factor da erosão mecânica do solo.

High-dose sequential chemotherapy (ICE) under circulating progenitor cells (CPC) protection in patients with small cell lung carcinoma (SCLC). Preliminary report on a multicentric study

Starting in February 1994, 20 patients (pt) with a median age of 50 years(range 41-63) from 7 European centers have been included. Completedata were obtained in 16 patients so far. CPC were mobilized with chemo(Epirubicine 75 mg/m2 /d, 01 + 02) followed by G-CSF 5 p.gfkg/d for14 days. HD chemo consisted in 3 sequential courses of ICE regimen(UOs. 10 g/m2 , Carbo. 1200 mg/m2 and Etop. 1200 mg/m2 ) underCPC protection and G-CSF 5 p.g/kg/d. Out of the 16 pt, 12 completedfull program (3 cycles). One pt died of septic shock before receivingany ICE course. One pt died during the first ICE of renal insufficiency.Two pt had only 2 courses because of toxicity. Among the 16 pt, responserate (RR) was: 7 CR, 6 PR, 1 PO; 3 pt are not evaluable dueto early withdrawal (overall RR: 13/16 = 81 %). Thirty-nine cycles ofHD chemo were given with a median hematological recovery of 9 days(range 7-12) until neutro. counts> 1.0 x 109 /1 and 9 days (range 717)until thrombo. > 20 x 109 /1. No cumulative, hematological toxicitywas seen. Accrual of patients is still ongoing and updated results will bepresented.

Proverbes, dictons et expressions imagées dans l’enseignement/apprentissage du FLE, dans le secondaire au Cap-Vert.

Pour bien maîtriser une langue, il faut sans doute en avoir une connaissance la plus large possible, ce qui demande alors l’enseignement/apprentissage de tous les éléments qui la composent. Dans ce cas, il est très important de savoir quels sont, parmi ces éléments, ceux qui sont amenés en classe et comment ils y sont présentés. Il y en a certains qui ne fi-gurent pas dans le programme destiné à l’enseignement/apprentissage de la langue fran-çaise. S’ils l’étaient, probablement ils seraient enseignés. Mais, d’après notre constat, non seulement ils ne figurent pas, comme ils ne sont pas ou presque pas traités en cours par l’initiative des professeurs, bien qu’ils soient parmi les éléments les plus importants dans l’apprentissage d’une langue. Très souvent, ce sont ces éléments qui sont à la base de la motivation pour l’apprentissage des langues puisqu’ils constituent, d’une certaine manière, le charme et la beauté d’une langue. Nous en avons pris trois (proverbe, dicton et expres-sion imagée), qui peuvent représenter la manière de vivre ; de penser ; la culture, les cou-tumes et les habitudes d’un peuple. Il faut préciser que ce constat nous l’avons fait depuis longtemps. Par conséquent, nous avons décidé de traduire l’inquiétude que cette problématique provoque chez nous en ce travail de recherche qui a été mené sous le thème de : Proverbes, dictons et expres-sions imagées dans l’enseignement/apprentissage du FLE, dans le secondaire au Cap- Vert. Dans l’ensemble, ce travail est composé de trois parties. Dans la première partie, après les consultations de documents, nous avons proposé une réflexion sur le proverbe, le dicton et l’expression imagée en ce qui concerne leur origine et leur contexte social, temporel, leur durée, et leur situation actuelle par rapport à leur utilisation ou leur étude. Nous en avons également présenté quelques définitions, en insistant sur la distinction entre les mêmes, vu que pendant les recherches, nous avons constaté qu’il y a parfois, une confusion entre eux. Puis, dans la deuxième partie, à travers des enquêtes qui ont été menées sur le terrain dans quelques lycées de Praia, nous avons présenté sous forme d’analyse, la situation ac-tuelle concernant le recours aux proverbes, dictons et expressions imagées par le professeur dans ses cours, bien comme l’intérêt et la motivation des élèves face aux mêmes. Finalement, dans la troisième et dernière partie, nous avons dressé une liste composée de proverbes, dictons et expressions imagées que nous avons fait accompagner de leur pays d’origine, quand cela a été possible. Ils ont été analysés et nous avons essayé de montrer également, l’utilité pratique de leur message, soit pour les élèves à l’école, soit d’une ma-nière plus générale, pour toute la vie dans la société. Pour donner un caractère pratique à notre travail, nous avons fait quelques proposi-tions de techniques d’exploitation de proverbes, dictons et expressions imagées, dans les classes. C’est-à-dire, nous avons essayé d’apporter des suggestions qui peuvent être appli-quées à un éventuel engagement de la part des professeurs ou d’autres intervenants concer-nés à la résolution de la problématique qui a légitimé notre recherche.
