The aim of this experiment is to examine how recollection and familiarity change over time and whether there is a qualitative difference between familiar items that were previously recollected and items that have always been familiar. It might be that, when an item is initially recollected and becomes just familiar after a delay, this form of familiarity is actually a weak and partial recollection, qualitatively different from mere familiarity. To address this issue, a task have been developed in which, at study, participants encoded two series of 100 pictures representing scenes under respectively shallow and deep encoding conditions. Memory for these pictures was tested by means of a yes-no recognition test. Recognised items were classified as recollected or as familiar. Half of the pictures from each encoding condition were tested after 10 minutes and the other half were tested after 2 days. The results indicated that recollection decreased after 2 days while familiarity increased (deep encoding condition) or did not change (shallow encoding condition). This suggests that, among the items judged as familiar after 2 days, some items would have been recollected after 10 minutes and some were initially already familiar. Because deep encoding produced a higher proportion of recollection at the 10-minute interval, the proportion of recollection-changed-into-familiarity responses should be greater in this condition than in the shallow encoding condition. Whether there is a qualitative difference between these responses and pure familiarity responses should be explored in a fMRI experiment. [less ▲]

Limnothrissa miodon, a small pelagic clupeid fish introduced at the end of the 1950s into Lake Kivu, became an important resource for the human populations of this area. The total stock of pelagic fish populations of this lake was estimated in 2008 by two hydroacoustic surveys, using an EK60 split-beam sounder (frequency 70. kHz). The total fish stocks were estimated to be approximately 5000. t in the rainy season and 6000 tons in the dry season. These values are similar to previous estimations performed in the 1980s. During 2008, the stock did not fluctuate throughout the seasons; however, the spatial distributions were different in the two hydrological seasons. Interestingly, the L. miodon stock has appeared to remain stable over the last two decades, which suggests that the pelagic fishery in Lake Kivu has not been overexploited and that it is sustainable. © 2012 Elsevier B.V.

Warming of the climate system is unequivocal, as it is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice and rising global average sea level. In this framework, sea level rise is virtually certain. This will impact ecosystems, coastal areas, human health, and economies. Vietnam is very likely to be one of the most affected countries with its 3200 km of shorelines with amplified vulnerability in large areas already affected by subsidence such as the Mekong and Red River deltas. In January 2009, international broadcast news have relayed the information that 27 houses located on the southern coast of Vietnam, in the fishing village of Phan Thiet, 200 km east of Ho Chi Minh City, have collapsed and that another hundred buildings were also threatened of destruction. According to experts, this event was definitely one of the consequences of global warning. This article shows, using the multi dates of Google Earth, that this assumption is not correct and highlights the real causes of this rapid and inevitable retreat of the coastline in this village, namely the mismanagement of natural resources, the lack of land use planning and the non-existence of policies focused on natural hazard management in the uncontrolled construction the seaside resort of Mui Ne, a few kilometers east.

Using a new evaluation of satellite data, and simula- tions carried out with a regional climate model, it has been shown that the acceleration of surface melting of the Greenland ice sheet during the 1979-2005 period was twice as rapid as earlier studies had estimated. Between 1979 and 2005, the area of Greenland affected by melt at least one day per year in fact increased by 42%, and the average summer tempera- ture rose by 2.4°C. [less ▲]

With the Key Investor Information Document (KID), the new UCITS IV framework brings a useful standardized and simplified scheme to explain the risk of mutual funds to non-professional investors. The Synthetic Risk and Reward Indicator (SRRI) methodology defines how to assess a volatility equivalent for each type of funds, and recognizes the specificities of various types of investment vehicles in the process. The SRRI rests upon two key principles: (i) risk-volatility mapping: the level of risk can be adequately translated by the volatility of returns; and (ii) reward to volatility: there must be a positive connection between the level of risk borne by the individual investor and the associated reward in terms of returns. We show that the SRRI methodology does not guarantee that these two principles are respected in practice. By forcing any type of risk to be translated into a volatility estimate, the approach overlooks investor’s heterogeneity in the definition of risk. The SRRI synthetic approach is powerless to adequately reflect the trade-off between normal and extreme risks the way it is perceived by individual investors. It also ignores that fund returns are not necessarily only related to volatility. We show that the KID does not replace a proper investment profiling system. The analysis of investor profiles is a necessary complement to the KID in order to provide adequate advice to investors. We provide an approach, based on the linear-exponential utility function, that enables the financial advisor to address the heterogeneity of investors when defining the risk of an investment portfolio.

The multicolored Asian ladybeetle, Harmonia axyridis Pallas (Coleoptera: Coccinellidae), was introduced into Western Europe in the late 1990s. Since the late 2000s, this species has been commonly considered one of the most abundant aphid predators in most Western European coun- tries. In spite of the large amount of research on H. axyridis, information concerning its relative abundance in agroecosystems is lacking. This study aims to evaluate the abundance of H. axyridis within the aphidophage community in four crops situated in southern Belgium: wheat, Triticum aestivum L. (Poales: Poaceae), corn, Zea mays, potato, Solanum tuberosum (Solanales: Solanaceae), and broad bean Vicia faba (Fabales: Fabaceae). In order to assess the species diver- sity, the collected data were analyzed by considering (1) the species richness and (2) the evenness according to the Shannon diversity index. Eleven aphidophages were observed in every invento- ried agroecosystem, including five abundant species: three coccinellids, the seven-spotted ladybug, Coccinella septempunctata L. (Coleoptera: Coccinellidae), the 14-spotted Ladybird, Propylea quatuordecimpunctata, and H. axyridis; one hoverfly, the marmalade hoverfly, Episyr- phus balteatus De Geer (Diptera: Syrphidae); and one lacewing, the common green lacewing, Chrysoperla carnea Stephens sensu lato (= s.l.) (Neuroptera: Chrysopidae). Harmonia axyridis has been observed to thrive, breed, and reproduce on the four studied crops. Harmonia axyridis is the most abundant predator of aphids in corn followed by C. septempunctata, which is the main aphid predator observed in the three other inventoried crops. In wheat and potato fields, H. axyridis occurs in low numbers compared to other aphidophage. These observations suggest that H. axyridis could be considered an invasive species of agrosystems, and that potato and wheat may intermittently act as refuges for other aphidophages vulnerable to intraguild predation by this invader. Harmonia axyridis is not the most abundant aphid predator in the main Belgian crops. [less ▲]

Ambrosia artemisiifolia L. is an invasive species from North America, causing a health crisis in Europe due to its highly allergenic pollen. In France, there is a zone where the A. artemisiifolia populations are naturalized and invasive. Outside this area, populations are more rare and do not seem to expand. We tested if the performances of A. artemisiifolia are varying with competition level, and among geographical zones. The results show that populations from Belgium and Netherlands are not less efficient than invasive populations for the measured traits. [less ▲]

Within the Hautes-Fagnes Nature Reserve (Belgium) acidic and oligotrophic biotopes are developing on very acidified stony silt raised bogs. However, they are locally dominated by mesotrophic species. Based on the fact that there are several outcrops of tonalite in the region and particularly one in the Nature Reserve, a hypothesis to explain these singularities of the vegetation implies discontinuities of the bedrock provoked by intrusions of this magmatic rock in the Revinian layer covering the region. Seventeen plots containing Phragmites australis were examined and vegetation was described. Silt and soil water were sampled and analyzed for mineral contents in 15 sites. The differences of mineral composition between the P. australis plots and their surrounding environment confirmed the more mesotrophic characteristics of these plots (i.e. higher pH, higher Ca and Mg contents, lower Al content). However, the lower Zn, Pb and Fe contents would lead to reject the hypothesis of intrusions of tonalite since these elements are more abundant in the tonalite and its mineralization than in the Revinian rock. Nevertheless, the overall ecological conditions of the examined plots and the differences of plant species composition suggested that the observed chemical environment could be evoked for explaining the distribution of the mesotrophic species in the oligotrophic environment of the Nature Reserve. Consequently, an alternative hypothesis is proposed. [less ▲]

OBJECTIVES/HYPOTHESIS: It is becoming increasingly important for clinicians to demonstrate the impact of their interventions. The Sino-Nasal Outcome Test-22 (SNOT-22) questionnaire is a disease-specific questionnaire involving 22 symptoms combining rhinologic issues with general health issues. We evaluated the SNOT-22 score as a quality-of-life outcome measure in septorhinoplasty surgery. STUDY DESIGN: Outcome research. METHODS: We carried out a prospective case series in 76 patients undergoing septorhinoplasty. Their SNOT-22 scores were compared pre- and postoperatively. We also recorded individual symptom scores to study the impact of surgery. To check its reliability, the SNOT-22 score was correlated to patient-reported symptoms on a visual analogue scale. Patients were screened for comorbid conditions. Interactions with the surgical technique and/or with the initial sinonasal disease were sought. RESULTS: The SNOT-22 is a reliable and responsive outcome measure in septorhinoplasty surgery. Septorhinoplasty was especially effective at addressing nasal obstruction, discharge, olfaction, related sleep disturbance, and emotional symptoms such as embarrassment or frustration. Comparison to the visual analogue scale instrument confirmed the outcome measured by the SNOT-22. CONCLUSIONS: The SNOT-22 could be used in routine clinical practice to highlight the impact of nasal disease in each patient and to measure the outcome and the effectiveness of the surgical intervention.

The European mink (Mustela lutreola) is one of the most threatened carnivores in Europe, with fragmented populations in Belarus. Russia and Romania, as well in south-western France and northern Spain. Many populations have become extinct recently, or are declining. We investigated mitochondrial DNA variation, using the complete D-loop region, and concentrating oil the west European population. The aim was two-fold: to use the genetic information to advise on the conservation of European mink, and to begin to understand their history through the Pleistocene. Captive breeding and re-introduction programmes are underway, so it is particularly vital to know whether the West European population should be treated separately. We find that European mink probably colonised from a single refugium after the last glaciation. West European populations may be fixed for a single haplotype. also suggesting a common origin. Despite this evidence for gene flow, following the precautionary principle we suggest that mink from the three geographically separate populations (Romania, Eastern and Western Europe) should be managed separately, for the moment.

The objective of this study was to evaluate whether introducing the condensed wheat distillers soluble ProtiWanze® (PW) in diets of beef cattle has an impact on feeding costs, health and production of the animals. PW by-product from a Belgian bio-ethanol plant which utilized only wheat without bran, is an acid (pH=4) liquid feed rich in energy (VEM= 1130) and protein (TP= 282 mg/kg DM). PW supplementation from 9 to 13% on DM basis has been tested in 4 suckler cows’ farms for 4 months in 2011 and 2012. In 2011, 2 BB (H1 and H3) and 1 Blonde d’Aquitaine (H2: 23 cows) herds were evaluated and in 2012, the Blonde d’Aquitaine herd was replaced by a third BBB herd (H4: 42 cows). Every month, animals’ health and production were checked by the mean of Body Condition Score, Ruminal Fill, Fecal Consistency, Undigested Fraction and Locomotion Scores determination, as described by Zaaier et al.(2001) and Sprecher et al.(1997). Ruminal fluid was sampled by a stomach tube (Ruminator®) on 5 cows for pH, redox potential (Methylene blue test) and protozoa assessment (optical microscopy). Reproduction performances of this 2 year’s-period were analyzed. Price of a diet containing the same amount of proteins brought by a mixture of 1/3 soybean and 2/3 canola meal was calculated to verify whether introducing PW reduced feeding costs. Whatever the concentration of PW used, no adverse effect has been observed concerning reproduction, production performance, ruminal pH. Feeding costs were reduced by 0.08 €/cow/day in 2011 and by 0.02 €/cow/day in 2012. This lower spared amount in 2012 is the consequence of the reduction in PW protein concentration while its price increased. Anyway, comparison has to take into account the energy brought by this CDS as it has been suggested by Petersen’s equation, which compares CDS price with soybean meal but also with maize price. Further argument to be considered, especially in BB, is the high PW palatability, its low ruminal filling value and better roughage digestion. [less ▲]
