The influence of photoperiod on male courtship and nest-building in the Ring dove, Streptopelia risoria

McDonald, Pam January 1976 (has links)
The aim of this study was to examine the influence of photoperiod on the hormonal induction of courtship and nest-building behaviour in the male ring dove (Streptopelia risoria). In the first experiment 24 intact males were divided into two groups and held on long (16L:8D) or short (8L:16D) photoregimes for five weeks. They were then paired with intact females and their behaviour recorded. Long day males exhibited significantly higher levels of bowing and nest-soliciting. In the second experiment males were again held on long or short photoperiods. Half of each group received daily injections of testosterone propionate. Testosterone treatment eliminated differences in courtship between the two groups, but nest-building remained significantly higher in hormone-treated long day birds. The experiment was then repeated using TP-treated castrates. In this case courtship did not vary between long and short groups, although nest-building was still greater under the long photoregime. These results indicate that photoperiod alters male courtship by stimulating endogenous androgen production. The influence on nest-building, however, appears to be least partially dependent upon some other mechanism. / Science, Faculty of / Zoology, Department of / Graduate

Lärares och elevers attityder till tyska som moderna språk

Lutfiu, Valbone January 2016 (has links)
SammanfattningDen här uppsatsen handlar om elevers attityder till tyska språket och vad läraren gör för att stimulera elevernas intresse för tyska språket. För att undersöka detta har några elever som läser tyska samt tysklärare intervjuats. Jag valde att intervjua både eftersom det är intressant att få även lärarens syn på just detta. Studiens syfte är att hitta framgångsfaktorer för att eleverna ska välja tyskan som språkval . En kvalitativ intervju har genomförts med elever och språklärare där frågeställningar har gett svar på vad eleverna tycker i årskurs 6- 7 om sina språkval tyska, vilka faktorer påverkar elevers val av moderna språk och hur läraren gör för att eleverna ska bli intresserade av tyska språket. Resultatet från intervjuare visar att elevernas attityd till tyska språket är positiv när det gäller framtidens yrke eller studier. Exempelvis kan många elever som läser tyska tänka sig att studera eller jobba i tysktalande länder i framtiden. Elevernas inställning till tyska språket är mer positiv än jag förväntade mig. Eleverna som jag har tillfrågat och som läser tyska tycker om sitt språkval. Även de tysklärare som deltog i undersökningen tyckte att tyska är en bra val för elever eftersom att läsa språk ger även extra meritpoäng. En del vill bara ha meritpoängen som man får om man läser moderna språk, säger lärarna och de anser att tyska är lättast att lära sig av tyska, franska och spanska. De som har valt språket själv är oftast intresserade eller har anknytning till tyskan på något sätt. Eftersom det är ett aktivt val som eleven gör själv i samråd med sina föräldrar så är de flesta elever positivt inställda, säger de intervjuade lärare.

The Effects of the Chronic Administration of Nicotinamide in Traumatic Brain Injury

Goffus, Andrea 01 December 2010 (has links)
Previously, we have demonstrated that nicotinamide (NAm), a neuroprotective soluble B-group vitamin, improves recovery of function following traumatic brain injury (TBI). However, no prior studies have examined whether NAm is beneficial following continuous infusions over seven days post-TBI. The purpose of this study was to investigate the preclinical efficacy of NAm treatment as it might be delivered clinically; over several days by slow infusion. Rats were prepared with either unilateral controlled cortical impact (CCI) injuries over the somatosensory cortex (SMC) or sham procedures and divided into three groups: CCI-NAm, CCI-vehicle, and sham. Thirty minutes following CCI, Alzet osmotic mini-pumps were implanted subcutaneously. NAm was delivered at a rate of 50 mg/kg/day for seven days immediately post-CCI. On day seven following injury, the pumps were removed and blood draws were collected for serum NAm and nicotinamide adenine dinucleotide (NAD+) analyses. Starting on day two post-CCI, animals were tested on a battery of sensorimotor tests (bilateral tactile adhesive removal, locomotor placing, and limb-use asymmetry). Statistical analyses of the tactile removal and locomotor placing data revealed that continuous administration of NAm significantly reduced the initial magnitude of the injury deficit and improved overall recovery compared to the vehicle-treated animals. NAm treatment also significantly decreased limb-use asymmetry compared to vehicle-treated animals. Continuous infusion of NAm resulted in a significant serum elevation in NAm, but not NAD+, as well as significantly attenuated cortex tissue loss than un-treated animals. The NAm-treated group also had the lowest number of glial fibrillary acidic protein (GFAP) positive cells. No detrimental effects were seen following continuous infusion. The present results suggest that NAm delivered via a clinically relevant therapeutic regimen may truncate behavioral damage following TBI. Thus our results offer strong support for translation into the clinical population.
