This study evaluates the impact of the choice of the Economics elective course in secondary school on the performance in Economics at the University level. While several studies look at the impact on performance of the number of hours of mathematics in secondary school, less has been made regarding the impact of the secondary school Economics program. We match survey data from 360 students enrolled in the first year of the bachelors program in HEC-Management School of University of Liège, with administrative data and exam results. The methodological challenge is that students who choose Economics elective course in secondary school are likely to be different, in terms of motivation, from other students. To get rid of this potential bias, we approximate motivation using self-reported reasons for the choice of the elective courses, but also participation to non-mandatory tests and preparations before the exam. We also control for several individual characteristics (socio-economic background, age, gender, secondary school fixed effect, etc.) in order to compare students with similar abilities. Preliminary analysis shows that students who have chosen Economics elective course in the last year of secondary school do not perform better, or worse, at their University Economics exam, when controlling for the number of hours of mathematics they had in secondary school, as well as other individual characteristics. However, they are less likely to report their bachelor Economics course as being “difficult”. Overconfidence of students with higher previous economic knowledge may explain why they do not perform better than their peers. [less ▲]Detailed reference viewed: 10 (2 ULg)

Beekeepers suspected maize. Zea mays L., treated with imidacloprid to result in substantial loss of honey bee (Hymenoptera: Apidae) colonies in Belgium. The objective of this study was to investigate the potential impact of maize grown from imidacloprid-treated seeds on honey bee mortality. A survey of 16 apiaries was carried out, and all maize fields treated or not with imidacloprid were located within a radius of 3,000 m around the observed apiaries. Samples of honey, beeswax, and bees were collected in three colonies per apiary and analyzed for pesticide contain by liquid chromatography-tandem mass spectrometry and gas chromatography-tandem mass spectrometry. We first found significant correlation between the number of colonies per apiary and the mortality rates in an apiary. In addition, this mortality rate was inversely correlated with the surface of maize fields treated and not with imidacloprid, suggesting that this pesticide do not interact with bees fitness. Moreover, a very large number of our samples contained acarcides either prohibited or ineffective against varroa destructor (Anderson & Trueman) (Acari: Varroidae), suggesting that the treatment method used by the beekeepers to be inadequate for mite control. Our results support the hypothesis that imidacloprid seed-treated maize has no negative impact on honey bees. [less ▲]Detailed reference viewed: 428 (51 ULg)

Background. Recent studies suggest that implicit memory (especially perceptual implicit memory) persists during adequate general anaesthesia in adults. Studies in children, however, have failed to demonstrate implicit memory during general anaesthesia, possibly because of differences in methodological design. We therefore designed a prospective study with the aim of evaluating implicit memory in children undergoing general anaesthesia, using a perceptual memory test based on the mere exposure effect, previously tested in a control group. Methods. Twelve infrequent neutral words were played 12 times in a random sequence via headphones to 36 children aged 8–12 yr during elective or emergency surgery. The children were not premedicated, and general anaesthesia was maintained with isoflurane. The word presentation started immediately after the surgical incision. Within 36 h after the stimulus presentation, the memory was assessed by using a forced-choice preference judgement task. Time constraint and word deterioration with a low-pass filter were used to prevent the subjects from utilizing intentional retrieval. The implicit memory score was obtained by calculating the proportion of target words preferred, which was compared with the chance level (0.5). Results. The percentage of correct responses given by the children was comparable with the chance level. The memory score was mean (SD) 0.48 (0.16) (95% CI 0.43–0.53). Conclusions. The use of a perceptual implicit memory test based on the mere exposure procedure in children failed to reveal any evidence of implicit memory under general anaesthesia.

INTRODUCTION The objective of this study was to evaluate whether introducing the condensed distillers solubles Protiwanze® (PW) at different concentrations in dairy cows diet induces changes in milk production. MATERIAL AND METHODS Three herds (72 Holstein and 25 Brown Swiss, DIM = 101 ± 57; daily milk production = 34.90 ± 8.40 L) received successively two RTM differing in PW content for 4 weeks, including a 7-day transition: 0% and 10% on a dry matter basis for Herd 1 and 10% and 15% for Herd 2 and 3. Both concentrations were distributed alternatively and repeated twice, each cow being its own control. Rations were formulated to meet energy and nitrogen requirements. During each testing period, animals were scored (Body Condition, Rumen Fill, Fecal Consistency, Undigested Fraction according to Zaaier (2001)) and their milk production and composition were measured by the Dairy Herd Improvement. RESULTS AND CONCLUSION Increasing the level of PW did not significantly change milk production in any Herd: Values were for Herd 1 at PW0%: 33.08 ± 0.76 L, at 10%: 31.66 ± 0.68 L, for Herd 2 at PW10%: 32.85 ± 0.93 L and at 15%: 32.37 ± 0.89, for Herd 3 at PW10%: 28.71 ± 1.21 L and at 15%: 31.80 ± 1.16. In Herd 1, milk urea decreased from 243.80 ± 4.55 mg/L for PW0% to 218.05 ± 4.03 mg/L for PW10%, (p<0.01), while fat percentage increased from 3.38% ± 0.09 (PW0%) to 3.77% ± 0.08 (PW10%) (p<0.01). Concerning scores, unconclusive changes were observed. Although increasing level of PW in dairy cows diet did not change milk production or composition, it is profitable since PW is 30-40% cheaper than other protein supplements like soya and canola meals. Moreover, it allowed to lower milk cost price by 1,5 eurocent per liter, when used at higher concentration. [less ▲]Detailed reference viewed: 35 (0 ULg)

Rat uterus maintained in situ was used as a bioassay of kinins possibly released in vivo by hyperglycaemia or insulin. Intravenous injections of bradykinin induced contractions of rat uterus which were suppressed by HOE 140, a bradykinin B-2 receptor antagonist. Des-Arg(9)-bradykinin, a kinin B-1 receptor agonist, did not elicit any response. After propranolol, the effects of bradykinin were enhanced and dose-dependent. This potentiation did not appear in adrenalectomized rats. Captopril, an angiotensin-converting enzyme (ACE) inhibitor, largely increased the effects of bradykinin. In animals pretreated with propranolol, captopril and atosiban, an oxytocin antagonist, intravenous infusion of glucose induced hyperglycaemia and after a delay increased the uterine contractile activity. This contractile effect of glucose was abolished by HOE 140. Infusion of insulin with glucose induced contractions of the uterus. These responses did not appear or were suppressed by HOE 140 or by soya bean trypsin inhibitor (SBTI), a plasma kallikrein inhibitor. These results are direct evidence that insulin induces a release of kinins. (c) 2005 Elsevier B.V. All rights reserved. [less ▲]Detailed reference viewed: 21 (6 ULg)

In this paper, we set out to determine whether the link between deliberation and transformation (or between process and outcome) is as straightforward as deliberative democracy assumes. More specifically, our research question is threefold: (1) whether a high quality of deliberation does indeed lead to changes in attitudes, (2) whether a high quality of deliberation can lead to a higher appreciation of the members of the outgroup, and above all (3) whether group composition matters. We thus want to push the research on the transformative effects a little further, into political psychology grounds, and see whether these effects can also take place in deliberation between diametrically opposed groups. Our aim is thus not only to test the link between deliberation and transformation, but also to see whether deliberation can have its transformative effects in high conflict settings, i.e. in more real-life settings. Based on findings from two deliberative experiments organized in deeply divided Belgium, we argue that the quality of deliberation (and the perceived quality of deliberation) are only weakly linked to changes in outgroup attitudes, and that the main variable explaining shifts towards more positive outgroup feelings is actually the group composition. Participants who are confronted with the other side are less likely to hold more negative views of the outgroup after the deliberation. [less ▲]Detailed reference viewed: 41 (1 ULg)

In 385 patients with acute myocardial infarction, lactate dehydrogenase (LD; EC 18.104.22.168) isoenzymes were determined electrophoretically 24, 48, and 72 h after admission. At those times, LD-1/LD-2 ratios exceeding 1 were recorded in 78.9, 88.8, and 92.2% of the cases, respectively. LD-1 ranged from 181 to 2674 U/L, or 21.9 to 66.1% of the total activity. On the first day of hospitalization, 27.3% of the patients demonstrated abnormal LD-5 (greater than 6% of total LD); this finding dropped to 20.5% and 17.4% in the two following days. Early increases in LD-5 were most frequently observed in patients associating inferior infarcts with posterior or lateral extension and having a previous history of myocardial infarction. On day 1, LD-5 was significantly increased in early deceased patients as compared to long-term survivors (9.7% vs 4.9% of total LD, p less than 0.01). LD-5 definitely contributes to the prognostic efficiency of total LD in acute myocardial infarction, but does not replace it as a risk predictor. This study confirms the superiority of total LD over the isoenzyme measurements to achieve short-term prognostication [less ▲]Detailed reference viewed: 9 (0 ULg)

PURPOSE: To compare retrospectively the incremental value of indirect computed tomographic (CT) venography performed after multi-detector row CT pulmonary angiography and single-detector row CT pulmonary angiography for the diagnosis of venous thromboembolism (VTE). MATERIALS AND METHODS: The institutional ethics committee approved this study; informed consent was not required. The authors retrospectively reviewed results of 1100 combined single-detector row CT pulmonary angiographic and indirect CT venographic examinations (542 men, 558 women; mean age, 61 years +/- 17 [standard deviation]) (group 1) and 308 combined multi-detector row CT pulmonary angiographic and indirect CT venographic examinations (150 men, 158 women; mean age, 62 years +/- 18) (group 2), performed in 1408 patients suspected of having pulmonary embolism (PE). Frequency of deep venous thrombosis (DVT), PE, and VTE, and the incremental value of indirect CT venography were recorded in both groups. Data were compared by means of the Student t test for continuous data and z statistics for independent proportions. RESULTS: VTE, PE, and DVT were found in 23.3% (n = 256), 19.9% (n = 219), and 18.3% (n = 201) of the 1100 patients in group 1, respectively, and in 23.7% (n = 73), 17.2% (n = 53), and 18.8% (n = 58) of the 308 patients in group 2, respectively (P values ranging from .273 to .876). The incremental value of indirect CT venography was 14.4% (37 of 256 patients) in group 1 and 27.4% (20 of 73 patients) in group 2. CONCLUSION: Despite potential improved accuracy of multi-detector row CT pulmonary angiography for the diagnosis of PE, the addition of indirect CT venography increased the diagnosis of VTE in 27.4% of patients.
