Resilience of small-scale societies: a view from drylands

To gain insights on long-term social-ecological resilience, we examined adaptive responses of small-scale societies to dryland-related hazards in different regions and chronological periods, spanning from the mid-Holocene to the present. Based on evidence from Africa (Sahara and Sahel), Asia (south margin of the Thar desert), and Europe (South Spain), we discuss key traits and coping practices of small-scale societies that are potentially relevant for building resilience. The selected case studies illustrate four main coping mechanisms: mobility and migration, storage, commoning, and collective action driven by religious beliefs. Ultimately, the study of resilience in the context of drylands emphasizes the importance of adaptive traits and practices that are distinctive of small-scale societies: a strong social-ecological coupling, a solid body of traditional ecological knowledge, and a high degree of internal cohesion and self-organization.

From global advocacy to local resistance. Benin's experience of competency-based school curriculum

In the vein of the "Education for All" campaign to promote access to education, a wave of curriculum revision along the competency-based approach has swept francophone countries in sub-Sahara Africa, thus Benin. The current study documents local actors' various interactions with the curricular reform in the course of its implementation. Secondary data supplemented with qualitative research techniques such as semi-structured interviews with teachers, and focus group discussions with parents enable to relate the patterns of change, the challenges and resistance to change. The actors spectrum generated illustrates advocacy on one hand and resistance on the other. Advocacy of local actors reflects the global optimistic discourse on education and resistance is favoured by disappointing policy outcomes as well as contextual constraints. (DIPF/Orig.)

Convective Cold Pools over the Atlas Mountains and Their Influence on the Saharan Heat Low

The West African Monsoon (WAM) and its representation in numerical models are strongly influenced by the Saharan Heat Low (SHL), a low-pressure system driven by radiative heating over the central Sahara and ventilated by the cold and moist inflow from adjacent oceans. It has recently been shown that a significant part of the southerly moisture flux into the SHL originates from convective cold pools over the Sahel. These density currents driven by evaporation of rain are largely absent in models with parameterized convection. This crucial issue has been hypothesized to contribute to the inability of many climate models to reproduce the variability of the WAM. Here, the role of convective cold pools approaching the SHL from the Atlas Mountains, which are a strong orographic trigger for deep convection in Northwest Africa, is analyzed. Knowledge about the frequency of these events, as well as their impact on large-scale dynamics, is required to understand their contribution to the variability of the SHL and to known model uncertainties. The first aspect is addressed through the development of an objective and automated method for the generation of multi-year climatologies not available before. The algorithm combines freely available standard surface observations with satellite microwave data. Representativeness of stations and influence of their spatial density are addressed by comparison to a satellite-only climatology. Applying this algorithm to data from automated weather stations and manned synoptic stations in and south of the Atlas Mountains reveals the frequent occurrence. On the order of 6 events per month are detected from May to September when the SHL is in its northernmost position. The events tend to cluster into several-days long convectively active periods, often with strong events on consecutive days. This study is the first to diagnose dynamical impacts of such periods on the SHL, based on simulations of two example cases using the Weather Research and Forecast (WRF) model at convection-permitting resolution. Sensitivity experiments with artificially removed cold pools as well as different resolutions and parameterizations are conducted. Results indicate increases in surface pressure of more than 1 hPa and significant moisture transports into the desert over several days. This moisture affects radiative heating and thus the energy balance of the SHL. Even though cold pool events north of the SHL are less frequent when compared to their Sahelian counterparts, it is shown that they gain importance due to their temporal clustering on synoptic timescale. Together with studies focusing on the Sahel, this work emphasizes the need for improved parameterization schemes for deep convection in order to produce more reliable climate projections for the WAM.

Maailma joka muuttuu elokuvallisessa prosessissa – Ranskalaisen päiväkirjan (1961) dokumentaarisuudesta

Tutkimuksen aiheena on Jean Rouchin ja Edgar Morinin ohjaama elokuva Ranskalainen päiväkirja vuodelta 1961 ja sen dokumentaarisuus. Tutkielma osoittaa, miten cinéma vérité -tyylisuunta on tapa, jolla dokumentaarisuus Ranskalaisessa päiväkirjassa toteutuu. Tutkin, minkälaisia uusia näkökulmia teos pystyy dokumentaarisuudellaan aikakauteensa avaamaan. Tyylisuunta-ajattelun lisäksi tarkastelen dokumentaarisuutta myös metodina ja elokuvallisena keinona. Ranskalaisen päiväkirjan ohella alkuperäislähteenä on dokumenttielokuva Un été + 50 (2011), jossa elokuvan tekijät ja henkilöt kertovat tutkittavan elokuvan taustoista 50 vuotta elokuvan ilmestymisen jälkeen. Ranskalainen päiväkirja sijoittuu 1950- ja 1960-lukujen vaihteeseen, jolloin Ranska oli muuttumassa. Suurvalta-asema oli menetetty, ja uutta hyvinvointivaltiota rakennettiin epäyhtenäisen ja vieraantuneen kansakunnan varaan. Kolonialismin jälkimainingeissa ranskalaisten oli määriteltävä suhteensa muun muassa käynnissä olleeseen Algerian sotaan. Autosta oli tullut kulutuskulttuurin symboli, mutta kehittyvä teknologia alkoi tarjota mahdollisuuksia myös elokuvalle ja sen ilmaisukeinojen laajentamiselle. Tutkielma selvittää, miten uusi elokuvateknologia, elokuvanteon representaatiot ja elokuvan välittämä sisältö kytkeytyvät yhteen ja muodostavat perustan Ranskalaisen päiväkirjan dokumentaarisuudelle. Elokuva antaa mahdollisuuden pohtia, miten teknologia ja eri aikakausien ajatuskehikot ovat toimineet vuorovaikutuksessa keskenään. Tyylisuunta-ajattelu kytkee elokuvan myös aikakauden filosofisiin ja elokuvateoreettisiin virtauksiin. Muutoksen mahdollisuudet, todellisuuden luonne ja paikka askarruttivat niin ikään filosofeja, sosiologeja ja muiden alojen taiteilijoita.

GENETIC DIVERSITY AMONG SORGHUM LANDRACES OF SOUTHWESTERN HIGHLANDS OF UGANDA

Sorghum ( Sorghum bicolor L. Moench) is an economic and staple crop in sub-Saharan Africa. The genetic diversity in its germplasm is an invaluable aid for its crop improvement. The objective of this study was to assess the existing genetic diversity among sorghum landraces in the southwestern highlands of Uganda. A total of 47 sorghum landraces, collected from southwestern highlands of Uganda, were characterised using 12 qualitative and 13 quantitative traits. The study was conducted at Kachwekano Research Farm in Kabale District, at an altitude of 2,223 m above sea level, during growing season of December 2014 to August 2015. Panicle shape and compactness were the most varied qualitative traits. Grain yield (1.23 to 11.31 t ha-1) and plant height (144.7 to 351.6 cm) were among quantitative traits that showed high variability. Days to 50% flowering (115 to 130 days) showed the least variability. Results of UPGMA cluster analysis generated a dendrogram with three clusters. Panicle weight, leaf width, stem girth, exertion length, peduncle length, panicle shape and compactness, glume colour and threshability were major traits responsible for the observed clustering (P<0.001). Principal Component Analysis revealed the largest variation contributors.

First record of Pagellus bellottii (Teleostei: Sparidae) in the Bay of Biscay, France

The red pandora, Pagellus bellottii Steindachner, 1882, is a tropical and subtropical demersal Sparidae (Porgies) that lives over hard or sandy bottoms in coastal marine waters. It mostly occurs at depths ranging from 10 to 50 metres. It is distributed in the eastern Atlantic, from the Strait of Gibraltar to Angola and the Canary Islands where it is occasionally recorded (Bauchot and Hureau, 1986; Franqueville, 1983). The species is also recorded in the southwestern Mediterranean, in the Alboran Sea, off the Algerian coasts and in the Gulf of Gabes (Oral, 2010). The records of the species in the eastern Mediterranean, Syrian and Israeli waters (Fricke, et al. 2014, Fig. 1) is questioned. We consider these records are misidentification of Pagrus pagrus (Linnaeus, 1758). Pagellus bellottii was also included in the checklist of the fishes from Portugal as a consequence of records coming from the Algarve region, about 36°59′ N, 8° W, the northernmost records in Atlantic waters (de Castro, 1967; Erzini et al., 1996; Carneiro et al., 2014; Carneiro com. pers.). Some specimens were also recorded in Spanish Mediterranean waters, in the Bay of Almería about 36°47′ N, 2°25′ W (Lucena, et al. 1982), the northernmost records for the Mediterranean waters. Herein, the first record of P. bellottii in the Bay of Biscay is reported.

HERITABILITY FOR RESISTANCE TO ROSETTE DISEASE IN EXOTIC VALENCIA GROUNDNUTS

Groundnut rosette disease (GRD) is the most destructive virus disease of Valencia groundnuts ( Arachis hypogaea L.) in sub-Saharan Africa. Cultural, biological and chemical control measures have received limited success due to small scale farmers’ inability to use them. Use of host plant resistance provides the most effective and economically viable management option for the resource poor farmers. This study was conducted to determine heritability for resistance to GRD in Valencia groundnuts. Six crosses; Valencia C (P1) × ICGV-SM 90704 (P2), Valencia C (P1) × ICGV-SM 96801(P2), Valencia C (P1) × ICGV-SM 99566 (P2), NuMex-M3 (P1) × ICGV-SM 90704 (P2), NuMex-M3 × ICGV-SM 96801 (P2), and NuMex-M3 (P1) × ICGV-SM 99566 (P2), were made to generate F1, F2, BC1P1 and BC1P2 populations. Data on GRD severity were collected on a 1-9 score scale. Genetic Advance as a percentage of the mean (GAM) and heritability were estimated using variance components. Phenotypic Coefficient of Variation (PCV) and Genotypic Coefficient of Variation (GCV) estimates were high (20.04-70.1%) in the six crosses, except for Valencia C × ICGV-SM 96801(18.1%) and NuMex-M3 × ICGV-SM 96801(17.1%), which exhibited moderate GCV values. Broad and narrow sense heritability estimates for GRD disease score ranged from 64.1 to 73.7% and 31 to 41.9%, respectively, in all the crosses. GAM was high in all the crosses (21-50.7%), except for Valencia C x ICGV-SM 96801 (14.67), M3 x ICGV-SM 99566 (18%) and NuMex-M3 x ICGV-SM 96801 (13.5%) crosses that exhibited moderate GAM. The study revealed the presence of variability of GRD resistance, implying that genetic improvement of these exotic materials is possible.

On the way to universal coverage of maternal services in Iringa rural District in Tanzania. Who is yet to be reached?

Background: Strategies to tackle maternal mortality in sub-Saharan Africa include expanding coverage of reproductive services.Even where high, more vulnerable women may not access services. No data is available on high coverage determinants. We investigated this in Tanzania in a predicted high utilization area. Methods: Data was collected through a household survey of 464 women with a recent delivery. Primary outcomes were facility delivery and ≥4 ANC visits. Determinants were analysed using multivariate regression. Results: Almost all women had attended ANC, though only 58.3% had ≥4 visits. ≥4 visits were more likely in the youngest age group (OR 2.7 95% CI 1.32–5.49, p=0.008), and in early ANC attenders (OR 3.2 95% CI 2.04–4.90, p<0.001). Facility delivery was greater than expected (87.7%), more likely in more educated women (OR 2.7 95% CI 1.50–4.75, p=0.002), in those within 5 kilometers of a facility (OR 3.2 95% CI 1.59–6.48, p=0.002), and for early ANC attenders (OR 2.4 95% CI 1.20–4.91, p=0.02). Conclusion: Rural contexts can achieve high facility delivery coverage. Based on our findings, strategies to reach women yet unserved should include promotion of early ANC start particularly for the less educated, and improvement of distant communities' access to facilities.

The Sword and the Pen: Life Writings by Militant-Authors of the Việt Minh and Front de Libération Nationale (FLN)

This dissertation examines four life writings by militant-authors of the Việt Minh and Front de la Libération Nationale (FLN): Ngô Văn Chiêu’s Journal d’un combattant Viet-Minh (1955), Đặng Văn Việt’s De la RC 4 à la N 4: la campagne des frontières (2000), Si Azzedine’s On nous appelait fellaghas (1976), and Saadi Yacef’s two-volume La Bataille d’Alger (2002). In describing the Vietnamese and Algerian Revolutions through the perspectives of combatants who participated in their respective countries’ national liberation struggles, the texts reveal that four key factors motivated the militants and led them to believe that independence was historically inevitable: (1) a philosophical, political, and ideological framework, (2) the support of multiple segments of the local population, (3) the effective use of guerrilla and psychological warfare, and (4) military, moral, and political assistance provided by international allies. By fighting for the independence of their countries and documenting their revolutionary experiences, the four militant-authors leave their mark on the world using both the sword and the pen.

Seasonal differences in migration patterns of a soaring bird in relation to environmental conditions: a multi-scale approach

Many studies suggest that migratory birds are expected to travel more quickly during spring, when they are en route to the breeding grounds, in order to ensure a high-quality territory. Using data recorded by means of Global Positioning System satellite tags, we analysed at three temporal scales (hourly, daily and overall journey) seasonal differences in migratory performance of the booted eagle (Aquila pennata), a soaring raptor migrating between Europe and tropical Africa, taking into account environmental conditions such as wind, thermal uplift and day length. Unexpectedly, booted eagles showed higher travel rates (hourly speed, daily distance, overall migration speed and overall straightness) during autumn, even controlling for abiotic factors, probably thanks to higher hourly speeds, more straight routes and less non-travelling days during autumn. Tailwinds were the main environmental factor affecting daily distance. During spring, booted eagles migrated more quickly when flying over the Sahara desert. Our results raise new questions about which ecological and behavioural reasons promote such unexpected faster speeds in autumn and not during spring and how events occurring in very different regions can affect migratory performance, interacting with landscape characteristics, weather conditions and flight behaviour.

Internationalization process of TUBOFURO

The central objective of this case study was to formulate the strategy of internationalization of Tubofuro®, discriminating relevant points from its design to its implementation. This is a company located in Leiria, Ortigosa parish, which operates, among others, in the Portuguese PVC pipes industry for which currently the domestic market is clearly insufficient, given the oversupply compared to demand. Being Tubofuro® an exporting company since 2004, the work here developed specifically intended to increase sales to the foreign market, with this representing 45% of total company's business in 2018 increasing of the number of markets through new partners to enable the positioning of Tubofuro® among the main players in each market, particularly in South American markets, North African and European. To achieve the above objectives presented a case study was applied, centred on Tubofuro® company, target of the internationalization strategy. The search carried out for the formulation of the strategy has been supported on a thorough analysis of the external environment and internal characteristics of the company, for which were crossed different types of data, quantitative, qualitative, secondary data and primary data. From this work resulted the development of internationalization and international marketing plan for the next three years, whose objectives are based on entrance and consequent growth in new markets, including the market Chilean, Peruvian, Mexican, Argentine, Algerian and German, as well growth in the presence and turnover in the markets for which Tubofuro® already exports regularly, for example Spain, France, Tunisia and Morocco. Based on the production capacity of Tubofuro® company, which will not suffer any kind of investment for incrementing but only to update, it is expected that the appropriate response capacity for the company is 8 regular markets, and could eventually arise sporadic exports to other markets not interfering with the normal production capacity of the company. The suggestion of the presented markets resulted from the study of the final price based on the one that local customers purchase a product equal or similar to Tubofuro® and the number of potential existing customers in each market. The internationalization model known as Uppsala Model corresponds to the strategy adopted by the company to its internationalization process, taking into account the philosophy of senior management and the risk aversion of them. The sales team Tubofuro® demand for each market, export a full container registering customer feedback, including quality and flow capacity in the market in order to seek a partnership agreement with a local distributor, which allows the Tubofuro® go to step two above mentioned model. The partnership agreement is based on mutual commitment to technical cooperation and trade between the Tubofuro® and partner, in order to increase the performance capacity among local customers. Only if the market presents a greater demand to our supply capacity and be justified by cost / benefit ratio, the entry into this market through a joint venture or subsidiary is that the decision will be taken. Although this is a case study, which means that is adjusted to the concrete case Tubofuro® preventing generalization of findings, we believe that this work can be a useful example for other companies in the internationalization process or the methodology adopted in formulating strategy or the outputs and conclusions drawn.

Représentations des langues en contexte plurilingue algérien

Le début des années 2000 a constitué un tournant dans l’évolution de la situation sociolinguistique de l’Algérie, marqué notamment par une ouverture sur le plurilinguisme qui se manifeste aujourd’hui sur le terrain comme un fait établi. Cette dynamique appelle un regard renouvelé sur les représentations qu’ont les locuteurs algériens des différentes langues en contact. C’est l’objectif de cet article qui présente les résultats d’une enquête sur les représentations sociales des quatre langues en présence (arabe standard, arabe dialectal, berbère et français) chez une population d’étudiants universitaires. Cette recherche, qui se base sur la méthode d’analyse combinée (Maurer, 2013) a permis de mettre au jour la structure de la représentation sociale de chaque langue et de voir la prégnance des images qui circulent chez les locuteurs.
