Raising awareness for energy efficiency in the service sector: learning from success stories to disseminate good practices

International audienceEnergy efficiency in the service sector is a key issue because of the important growth of its energy consumption. The energy performance of buildings and equipment can be improved through technical investments, but this has to be linked with an efficient management and good practices in order to reach better energy efficiency levels in a cost-effective way. Experience feedback concerning awareness activities in the service sector highlights the interesting opportunities of energy efficiency improvements they represent. This paper first draws a synthesis of the available feedback in this area to detect factors of success for this kind of activities. More than twenty operations from Europe and North America were analyzed looking at items such as the stakeholders involved, the actions implemented, the communication means, and the evaluation performed. Then a case study describes an EDF pilot operation in South East of France. An awareness campaign was led in four particular EDF buildings to inform the employees of the best practices and to involve them to apply these advice. Different action packages were used to compare their efficiency. The evaluation emphasizes the success of the operation, with around 10% of energy savings (i.e. more than 270 MWh/a). More than 80% of the employees said they changed their energy behavior and other indicators show their commitment and satisfaction towards the campaign. Finally, suggestions are made to disseminate good practices at a broader scale, especially out of the "initiated" circle. Building up a know-how from the evaluation of past experiences makes easier the development of process such as networking, experience sharing, and including these activities in energy services offers and in white certificates systems

The demand for money in developing countries: Assessing the role of financial innovation

Traditional specifications of money demand have been commonly plagU4:!d by persistent overprediction, implausible parameter estimates, and highly autocorrelated errors. This paper argues that some of those problems stem from the failure to account for the impact of financial innovation. We estimate money demand for ten developing countries employing various proxies for the innovation process and provide an assessment of the relative importance of this variable. We find that financial innovation plays an important role in determining money demand and its fluctuations, and that the importance of this role increases with the rate of inflation.

Comparative Studies and the South American Gran Chaco

This article reviews the historical and present prospects of ethnohistorical and ethnographic work in the South American Gran Chaco. Geographically the Chaco is a semi-arid central South American plain, some one million square kilometers in size, encompassing portions of northern Argentina, eastern Bolivia, and western Paraguay. Average rainfall oscillates around 800 mm/yr, with the peripheries being wetter and the central Chaco drier. Some 250,000 indigenous people belonging to more than twenty ethnic groups live in the Chaco. Traditional ethno-linguistic categorization classifies them into six main linguistic groups: Mataco-maká (Wichí-Mataco, Chorote, Nivaclé-Chulupí, Maká), Guaycurú (Toba, Toba-Pilagá, Pilagá, Mocoví, Mbayá-Caduveo), Lule-Vilela (Chunupí), Lengua-Maskoi (Lengua, Sanapaná, Angaité, Enenlhet), Zamuco (Chamacoco-Ishir, Ayoreo) and Tupí-Guaraní (Ava-Chiriguano, Chané, Tapiete, Isoseño-Guaraní, and Guaraní Occidental). The last group is the largest, including nearly 100,000 people, of whom the majority live in Bolivia. Unlike their Amazonian and Andean counterparts, Chaco indigenous peoples have yet to establish transnational, pan-indigenous representative bodies of their own. The present position of Chaco scholars is in many ways isomorphic to that of Chaco indigenous peoples, as Chaco anthropology has not established itself as an internationally recognized field of endeavor. Nevertheless, recent scholarship in the region is currently producing an original synthesis of many of the long-standing concerns of Andeanist and Amazonianist scholarship, respectively. A case can also be made for a new direction for research, based upon intriguing anthropological and historical parallels between the North American Great Plains and the South American Gran Chaco. The very indefinition of Chaco scholarship may also be its principal strength, and the past and present directions of Chaco research both draw upon and make a persuasive case for returning to comparative and area studies approaches in anthropology

Anthropology of the South American Lowlands

Since the first contacts, the ’lowlands’ of South America have been defined in a residual way, as the term referred to all the regions that do not belong to the Andes: the immense Amazon, the Chaco, Patagonia and the Atlantic coast. In fact, the lowlands were thought of as a sort of negative image of the picture that Andean societies presented to the conquistadores: like Central America, with its kings and nobles, its numerous armies, its productive surpluses and its monumental constructions, the Andes and its inhabitants offered an exotic image, certainly. But it was also one that was more understandable or, at the very least, easier to identify: the image of a consolidated state, of farming and sedentary peoples, with a certain demographic density, and more familiar to Europeans. Therefore it is not surprising that in trying to understand the peoples who lived east of the Andes, beyond the Piedmont, European observers most often recycled the prejudices, generic categories and stereotypes of savagery or barbarity that were held by the Andean peoples themselves, who thought of the peoples of the lowlands through the reductive prism of the ’Anti’, the ’Chuncho’ or the ’Chiriguano’ – all generic and contemptuous terms, equivalent to our ’savages’ or ’barbarians’.Fil: Combes de Guzman, Isabelle.

Galaxy Zoo: Passive Red Spirals

We study the spectroscopic properties and environments of red spiral galaxies found by the Galaxy Zoo project. By carefully selecting face-on, disk dominated spirals we construct a sample of truly passive disks (not dust reddened, nor dominated by old stellar populations in a bulge). As such, our red spirals represent an interesting set of possible transition objects between normal blue spirals and red early types. We use SDSS data to investigate the physical processes which could have turned these objects red without disturbing their morphology. Red spirals prefer intermediate density regimes, however there are no obvious correlations between red spiral properties and environment - environment alone is not sufficient to determine if a spiral will become red. Red spirals are a small fraction of spirals at low masses, but are a significant fraction at large stellar masses - massive galaxies are red independent of morphology. We confirm that red spirals have older stellar popns and less recent star formation than the main spiral population. While the presence of spiral arms suggests that major star formation cannot have ceased long ago, we show that these are not recent post-starbursts, so star formation must have ceased gradually. Intriguingly, red spirals are ~4 times more likely than normal spirals to host optically identified Seyfert or LINER, with most of the difference coming from LINERs. We find a curiously large bar fraction in the red spirals suggesting that the cessation of star formation and bar instabilities are strongly correlated. We conclude by discussing the possible origins. We suggest they may represent the very oldest spiral galaxies which have already used up their reserves of gas - probably aided by strangulation, and perhaps bar instabilities moving material around in the disk.Comment: MNRAS in press, 20 pages, 15 figures (v3

Etnonimia wichí: Cien hipótesis para mil y un nombres

El artículo rastrea los diversos nombres que sirvieron para designar a los wichís y weenhayek del Chaco central argentino y boliviano, desde el s. XVII hasta la actualidad. A medida que avanza la conquista y colonización del área, estos nombres pasan de términos vagos, genéricos y multiétnicos a nombres que refieren a un único complejo etnolingüístico y, finalmente, a sectores relativamente grandes de ese “complejo”. Se muestra que el uso de “wichí” y “weenhayek” para designar, respectivamente, a los grupos argentinos y bolivianos es bastante reciente: donde existían un “complejo étnico” y un “continuum lingüístico”, las organizaciones religiosas y los antropólogos identificaron “pueblos” y “lenguas”, y luego la academia, las ONG y los Estados consagran, anquilosan y difunden estas etiquetas como etnónimos.The paper tracks several names that designated the Wichí and Weenhayek of the Argentinian and Bolivian Chaco since the 17th century. With the conquest and colonization of the region, these vague, generic and multi-ethnic labels gradually started to designate certain ethnolinguistic complexes, and even relatively vast portions of those complexes. The paper shows that the use of “Wichí” and “Weenhayek” to name, respectively, Argentina and Bolivia groups is quite recent: where there was only an ethnic complex and a linguistic continuum, religious organizations and anthropologists identified “nations” and “languages”, and then the agendas of academy, NGOs and the State spread the use of these labels as ethnonyms.Fil: Montani, Rodrigo Matias.

Robust intensification of global ocean Eddy Kinetic Energy from three decades of satellite altimetry observations

Ocean mesoscale variability, a key component of the climate system, influences ocean circulation and heat, gas, carbon and nutrient distribution. Trends on Eddy Kinetic Energy (EKE), a metric measuring its intensity, are investigated using two products constructed from 30 years of altimetric observations. Statistically significant positive trends in globally-averaged EKE reveal a strengthening of 1-3% per decade. Regions of intense mesoscale activity become more energetic than other areas. Robust positive EKE trends are observed in the Kuroshio Extension and the Gulf Stream, with remarkable EKE increases of ~50% and ~20%, respectively, over the last decade. Our study opens a new question into how the observed Gulf Stream strengthening impacts the AMOC, and challenges existing climate models emphasizing the necessity for improved small-scale ocean process representation

The 'PUCE CAFE' Project: the First 15K Coffee Microarray, a New Tool for Discovering Candidate Genes correlated to Agronomic and Quality Traits

Background: Understanding the genetic elements that contribute to key aspects of coffee biology will have an impact on future agronomical improvements for this economically important tree. During the past years, EST collections were generated in Coffee, opening the possibility to create new tools for functional genomics. Results: The "PUCE CAFE" Project, organized by the scientific consortium NESTLE/IRD/CIRAD, has developed an oligo-based microarray using 15,721 unigenes derived from published coffee EST sequences mostly obtained from different stages of fruit development and leaves in Coffea Canephora (Robusta). Hybridizations for two independent experiments served to compare global gene expression profiles in three types of tissue matter (mature beans, leaves and flowers) in C. canephora as well as in the leaves of three different coffee species (C. canephora, C. eugenoides and C. arabica). Microarray construction, statistical analyses and validation by Q-PCR analysis are presented in this study. Conclusion: We have generated the first 15 K coffee array during this PUCE CAFE project, granted by Genoplante (the French consortium for plant genomics). This new tool will help study functional genomics in a wide range of experiments on various plant tissues, such as analyzing bean maturation or resistance to pathogens or drought. Furthermore, the use of this array has proven to be valid in different coffee species (diploid or tetraploid), drastically enlarging its impact for high-throughput gene expression in the community of coffee research

Extracorporeal Membrane Oxygenation for Severe Acute Respiratory Distress Syndrome associated with COVID-19: An Emulated Target Trial Analysis.

RATIONALE: Whether COVID patients may benefit from extracorporeal membrane oxygenation (ECMO) compared with conventional invasive mechanical ventilation (IMV) remains unknown. OBJECTIVES: To estimate the effect of ECMO on 90-Day mortality vs IMV only Methods: Among 4,244 critically ill adult patients with COVID-19 included in a multicenter cohort study, we emulated a target trial comparing the treatment strategies of initiating ECMO vs. no ECMO within 7 days of IMV in patients with severe acute respiratory distress syndrome (PaO2/FiO2 <80 or PaCO2 ≥60 mmHg). We controlled for confounding using a multivariable Cox model based on predefined variables. MAIN RESULTS: 1,235 patients met the full eligibility criteria for the emulated trial, among whom 164 patients initiated ECMO. The ECMO strategy had a higher survival probability at Day-7 from the onset of eligibility criteria (87% vs 83%, risk difference: 4%, 95% CI 0;9%) which decreased during follow-up (survival at Day-90: 63% vs 65%, risk difference: -2%, 95% CI -10;5%). However, ECMO was associated with higher survival when performed in high-volume ECMO centers or in regions where a specific ECMO network organization was set up to handle high demand, and when initiated within the first 4 days of MV and in profoundly hypoxemic patients. CONCLUSIONS: In an emulated trial based on a nationwide COVID-19 cohort, we found differential survival over time of an ECMO compared with a no-ECMO strategy. However, ECMO was consistently associated with better outcomes when performed in high-volume centers and in regions with ECMO capacities specifically organized to handle high demand.
