There is evidence that serotonin [5-hydroxytryptamine (5-HT)] is involved in the physiological responses to hypercapnia. Serotonergic neurons represent the major cell type (comprising 15-20% of the neurons) in raphe magnus nucleus (RMg), which is a medullary raphe nucleus. In the present study, we tested the hypothesis 1) that RMg plays a role in the ventilatory and thermal responses to hyperca...

seems to be original. This goes to show that the human foetus exhibits signs of animation parallel with those of bodily configuration. In significance and purpose Albertus' observation is, therefore, far removed from Harvey's ideas, although the method is the same. It is not unlikely that Harvey was familiar with Albertus' text in which comparative embryology was treated on a broad Aristotelian...

This report describes a study project done at the Rudolf Magnus Institute (RMI) in the eld of neural network development. The goal of this study is to develop a neural network that is able to automatically classify rat behaviour from video. This project was started because of the great di erences in perception and classi cation of rat behaviour between human observers. Chapter 1 consists of a g...

We investigate the e¤ect of employee heterogeneity on the incentive to put forth e¤ort in a market-based tournament. Employers use the tournament’s outcome to estimate employees’ abilities and accordingly condition their wage o¤ers. Employees put forth e¤ort, because by doing so they increase the probability of outperforming the rival, thereby increasing their ability assessment and thus the wa...

Are fairness concerns of relevance to environmental economics and, if so, are they sufficiently structured to improve analysis in this field? On both of these questions, we answer in the affirmative, arguing that people’s fairness views are based on both general rules and the context, where context refers to the set of variables and persons employed to interpret and apply the principles. The fa...

We examine the relationship between portfolio manager ownership, closed-end fund premiums/discounts, and future returns. Using a sample of 592 closed-end funds in 2005, representing 95% of the entire industry, we find that fund manager ownership has a positive and economically significant impact on fund premiums and future fund performance measured using both NAV and price returns. Furthermore,...

The helminth burdens of 17 springbok from 2 localities in the Transvaal and of 4 springbok from the western Cape Province were determined. Eight of the animals from the Transvaal and the 4 from the Cape Province were also examined for arthropod parasites. In all, 26 helminth species, 5 species of ixodid ticks and 4 species of lice were recovered from the springbok. Of the helminths Dictyocaulus...

John Earman and John T. Roberts advocate a challenging and radical claim regarding the semantics of laws in the special sciences: the statistical account. According to this account, a typical special science law “asserts a certain precisely defined statistical relation among well-defined variables” (Earman and Roberts 1999) and this statistical relation does not require being hedged by ceteris ...
