Le Réalisme dans le roman policier : Une Analyse du réalisme des décors, des personnages et de l'enquête dans deux romans policiers

Ce mémoire a pour but de comparer deux romans policiers contemporains et ayant eu un grand succès, l’un écrit par Henning Mankell dont la traduction française a paru sous le titre Les Morts de la Saint-Jean et le second est Pars vite et reviens tard de Fred Vargas. L’objectif de la candidate est d’essayer de trouver les éléments réalistes dans le décor, les personnages et l’enquête. Pour ce qui est du premier paramètre, la candidate montre que Mankell n’essaie jamais de cacher la vérité derrière une surface idéale ; il en va de même pour Vargas qui accentue les points de vue divergents des Français sur la réalité de leur pays. En ce qui a trait aux personnages, on distingue dans le portrait qu’en fait Mankell un combat compliqué et non manichéen, proche de la réalité psychologique; idem pour ceux de Vargas, mais le réalisme est quelque peu atténué par un recours au mystère. Enfin, l’enquête menée par Wallander aboutit un peu par hasard grâce à son intuition alors qu’Adamsberg résout l’énigme grâce à sa faculté de voir, de s’imaginer et d’aller au-delà de la capacité des autres. La conclusion générale du mémoire est que ces deux œuvres sont tout à fait réalistes, mais à un degré un peu différent. Le roman de Mankell l’est sans doute davantage dans la mesure où le recours au mystère est écarté et que l’enquête est menée de façon logique alors que le roman de Vargas, tout en suivant les règles de la logique, a tendance à faire appel au merveilleux. En tout état de cause, il s’agit de deux œuvres réalistes comportant un côté romantique plus ou moins bien exprimé.

En okänd svensk folkrörelse : Svenska Skolornas Fredsförenings fredsarbete 1922-1929

Den här undersökningen ämnar kartlägga Svenska Skolornas Fredsförenings (SSF) fredarbete under 1920-talet, en ansats som inte tidigare gjorts på detta sätt. Medlemmarna i denna före­ning arbetade outtröttligt för en fredligare värld, där fredsfostran av unga sågs som den bästa metoden för att få till stånd en internationell varaktig fred. Syftet med undersökningen är att, genom en kvalitativ innehållsanalys av delar av SSFs bevarade tryckta skrifter, beskriva SSFs principer och pedagogiska metoder samt utröna varför de ansåg fredsfostran riktad mot skolan som viktig. Resultaten visar att SSF hade ambitionen att genom internationellt samarbete på­verka barnen i en sådan riktning att de aldrig skulle kunna ta till vapen för att lösa konflikter. Istället skulle barn lära sig att tänka kritiskt, vara självständiga och få en förståelse för andra folks kulturer. Genom att respektera och leva efter kristna, jämlika och demokratiska ideal, menade SSF att krig skulle gå att förhindra.  

Bereden (beredskaps)väg för kvinnorna Lärarinneförbundet i krigets skugga. : En studie i folkskollärarinnornas fackliga och politiska aktivitet under be-redskapsåren 1940-1945

Denna studies syfte är att försöka kartlägga folkskollärarinnornas fackliga och politiska akti-vitet under andra världskrigets beredskapsår i Sverige, samt belysa flera av de problem 40-talets kvinnoorganisationer stod inför. Det empiriska matrealet har i huvudsak bestått av utvalda artiklar, annonser och notiser i folk-skollärarinnornas fackliga tidningsorgan Lärarinneförbundet (LF). Resultatet presenteras te-matiskt samt i tabellform. De kvinnliga folkskollärarnas ambition under beredskapsåren var att förbereda en evig världs-fred, misstagen från första världskriget fick inte upprepas. Då var de, så att säga, tagna på sängen vid krigsutbrottet. Denna gång var de förberedda och inte minst, redan organiserade. Bereden väg för Herran har i denna studie, i jämställdhetens namn ändrats till Bereden väg för Kvinnan, med tanke på att dessa fackligt aktiva pionjärkvinnor i mångt och mycket, be-redde väg för kommande generationer av yrkeskvinnor

Protocols between programs and proofs

In this paper we describe a new protocol that we call the Curry-Howard protocol between a theory and the programs extracted from it. This protocol leads to the expansion of the theory and the production of more powerful programs. The methodology we use for automatically extracting “correct” programs from proofs is a development of the well-known Curry-Howard process. Program extraction has been developed by many authors, but our presentation is ultimately aimed at a practical, usable system and has a number of novel features. These include 1. a very simple and natural mimicking of ordinary mathematical practice and likewise the use of established computer programs when we obtain programs from formal proofs, and 2. a conceptual distinction between programs on the one hand, and proofs of theorems that yield programs on the other. An implementation of our methodology is the Fred system. As an example of our protocol we describe a constructive proof of the well-known theorem that every graph of even parity can be decomposed into a list of disjoint cycles. Given such a graph as input, the extracted program produces a list of the (non-trivial) disjoint cycles as promised.

Effects of creatine loading and prolonged creatine supplementation of body composition, fuel selection, sprint and endurance performance in humans

Most research on creatine has focused on short-term creatine loading and its effect on high-intensity performance capacity. Some studies have investigated the effect of prolonged creatine use during strength training. However, studies on the effects of prolonged creatine supplementation are lacking. In the present study, we have assessed the effects of both creatine loading and prolonged supplementation on muscle creatine content, body composition, muscle and whole-body oxidative capacity, substrate utilization during submaximal exercise, and on repeated supramaximal sprint, as well as endurance-type time-trial performance on a cycle ergometer. Twenty subjects ingested creatine or a placebo during a 5-day loading period (20g·day^-1) after which supplementation was continued for up to 6 weeks (2g·day^-1). Creatine loading increased muscle free creatine, creatine phosphate (CrP) and total creatine content (P<0.05). The subsequent use of a 2g·day^-1 maintenance dose, as suggested by an American College of Sports Medicine Roundtable, resulted in a decline in both the elevated CrP and total creatine content and maintenance of the free creatine concentration. Both short- and long-term creatine supplementation improved performance during repeated supramaximal sprints on a cycle ergometer. However, whole-body and muscle oxidative capacity, substrate utilization and time-trial performance were not affected. The increase in body mass following creatine loading was maintained after 6 weeks of continued supplementation and accounted for by a corresponding increase in fat-free mass. This study provides definite evidence that prolonged creatine supplementation in humans does not increase muscle or whole-body oxidative capacity and, as such, does not influence substrate utilization or performance during endurance cycling exercise. In addition, our findings suggest that prolonged creatine ingestion induces an increase in fat-free mass.

The presence of GABA in gastropod mucus and its role in inducing larval settlement

Chemical substances that induce larval settlement have been the focus of many gastropod studies due to the importance of wild stock recruitment and production within aquaculture facilities. Gamma-aminobutyric acid (GABA), GABA analogs, and GABA-mimetics associated with certain crustose coralline algae (CCA), are known to induce larval settlement in commercial abalone (Haliotis) species, and other gastropods. Furthermore, mucus secreted from these gastropods has been shown to induce larval settlement, but the stimulatory components of mucus have not been thoroughly investigated. We now present data confirming that GABA is the settlement-inducing effector molecule contained within abalone mucus. To do this, we initially generated anti-GABA for use in immunoenzyme and immunofluorescent microscopy. Using these techniques GABA was identified in the nerves and epithelial cells of the foot, including mucus. Dried mucus samples subject to HPLC analysis revealed a mean concentration of 0.68 mM GABA after sample rehydration. The presence of GABA in these samples was confirmed by time-of-flight mass spectroscopy (TOF-MS). In addition, GABA was detected in the mucus of several abalone species and other gastropods by immunocytochemistry. Subsequent bioassays using both dry and fresh mucus strongly promoted induction of larval settlement.

Sex difference in the suppressive effect of cortisol on pulsatile secretion of luteinizing hormone in sheep

We tested the hypothesis that there are sex differences in the inhibitory effect of cortisol on pulsatile LH secretion and pituitary responsiveness to GnRH in gonadectomized sheep. In experiment 1, pulsatile LH secretion was examined in gonadectomized ewes and rams infused with either saline, a low (250 µg/kg·h) or a high (500 µg/kg·h) dose of cortisol for 30 h. In experiment 2, direct pituitary actions of cortisol were assessed by monitoring LH pulse amplitude in response to exogenous GnRH in hypothalamo-pituitary disconnected ewes and rams infused with the low dose of cortisol. In experiment 1, the mean (±SEM) plasma LH concentration was (P < 0.05) reduced significantly during cortisol infusion in both sexes, but the effect was greater in rams. In ewes, LH pulse amplitude and frequency were reduced (P < 0.05) at the high, but not the low, cortisol dose, whereas total LH output (LH pulse amplitude multiplied by frequency) was reduced (P < 0.05) at both doses. In rams, LH pulse frequency and amplitude and total LH output were (P < 0.05) reduced significantly at both cortisol doses. In experiment 2, plasma LH concentration and pulse amplitude in response to exogenous GnRH were not affected by infusion of cortisol in either sex. We conclude that gonadectomized rams are more sensitive than gonadectomized ewes to the effects of cortisol to inhibit LH secretion and that sex differences exist in the specific actions of cortisol on LH pulses. The results of experiment 2 suggest that intact hypothalamic input to the pituitary is necessary for cortisol to inhibit pituitary responsiveness to GnRH.

Cortisol interferes with the estradiol-induced surge of lutenizing hormone in the ewe

Two experiments were conducted to test the hypothesis that cortisol interferes with the positive feedback action of estradiol that induces the luteinizing hormone (LH) surge. Ovariectomized sheep were treated sequentially with progesterone and estradiol to create artificial estrous cycles. Cortisol or vehicle (saline) was infused from 2 h before the estradiol stimulus through the time of the anticipated LH surge in the artificial follicular phase of two successive cycles. The plasma cortisol increment produced by infusion was ∼1.5 times greater than maximal concentrations seen during infusion of endotoxin, which is a model of immune/inflammatory stress. In experiment 1, half of the ewes received vehicle in the first cycle and cortisol in the second; the others were treated in reverse order. All ewes responded with an LH surge. Cortisol delayed the LH surge and reduced its amplitude, but both effects were observed only in the second cycle. Experiment 2 was modified to provide better control for a cycle effect. Four treatment sequences were tested (cycle 1-cycle 2): vehicle-vehicle, cortisol-cortisol, vehicle-cortisol, cortisol-vehicle. Again, cortisol delayed but did not block the LH surge, and this delay occurred in both cycles. Thus, an elevation in plasma cortisol can interfere with the positive feedback action of estradiol by delaying and attenuating the LH surge.

Partnerships for skilling a seasonal workforce

As a group, seasonal workers tend to fall through the formal training net. The temporary nature of their work and the traditional understanding that seasonal work is unskilled has provided little impetus for workers, employers, providers or government to consider formal training. In this qualitative study of two regions, one in Circular Head, Tasmania and the other in Wide Bay-Burnett, Queensland, collaborative arrangements between stakeholders resulted in training benefiting seasonal workers, employers and the regional industry.The study showed that training must be integrated into industry and community processes and planning at a regional level to ensure training is beneficial to and accepted by seasonal workers and employers. This paper explores who was involved in these regional collaborative arrangements, how the collaborative arrangements came into being and how plans were put into action.

Cortisol delays the estradiol-induced LH surge : is this dependent on prior ovarian steroid exposure?

Glucocorticoids can inhibit pulsatile LH secretion and can delay or even block the preovulatory LH surge. Previous work in ovariectomized ewes has indicated that cortisol can delay the estradiol-induced LH surge in an artificial follicular phase model but the results suggest this effect may be influenced by prior exposure to ovarian steroids. Here we tested the hypothesis that this disruptive effect of cortisol on the positive feedback action of estradiol is dependent on prior exposure to the ovarian steroidal milieu of the estrous cycle. Using long-term ovariectomized ewes, sequential artificial estrous cycles were created in the anestrous season by treatment and subsequent withdrawal of progesterone (CIDRs inserted for 9 d) followed by estradiol implants simulating the pre-ovulatory estradiol rise that induces the LH surge. Following the first artificial estrous cycle, a second cycle was initiated. Progesterone was again administered for 9 d followed by a second artificial follicular phase two weeks later. Beginning 2 hr prior to estradiol administration and ending at 40 hr, animals received either a cortisol infusion (elevate plasma levels to ∼170 ng/ml) or vehicle. Jugular blood was sampled hourly to assess occurrence and timing of the LH surge. Four different treatment sequences were tested (Cycle 1-Cycle 2): cortisol-cortisol; vehicle-cortisol; cortisol-vehicle; and vehicle-vehicle (n=5-6/sequence). If prior exposure to the ovarian steroidal milieu of the estrous cycle was necessary for cortisol to interfere with the positive feedback action of estradiol, then we would predict that cortisol would only delay the LH surge when it was delivered in Cycle 2 but not Cycle 1. Our results failed to support this prediction. Cortisol delayed the surge in both cycles (p<0.01), and the extent of the delay was the same in both Cycles 1 and 2 (4 hrs). Cortisol did not significantly affect surge amplitude in either cycle. These findings reinforce our previous conclusion that cortisol can delay the estradiol-induced LH surge but they do not support the hypothesis that this action of cortisol is dependent upon exposure to the ovarian steroidal milieu of the previous estrous cycle.
