Title: The effect of meditation on cortisol levels in saliva Objectives: The main objective of the research project in this master's thesis was to objectively (based on changes in cortisol levels) and subjectively (by method of questionnaire) study the effect meditation has on stress levels. Methods: The objective method in this work was measuring cortisol in saliva with the help of an established and certified ELISA method on an ELISA reader device. The cortisol level was measured before meditation and after meditation. A method of questionnaire was used to determine the subjective emotions and feelings of the participants before and after meditation. The total surveyed group consisted of 25 healthy men, students of UK FTVS with a valid medical exam, between the ages of 19 - 35. The experimental part and data collection were conducted in two phases. (i) First, it was determined, on ten of the same participants during two consecutive days, which type of meditation (static breathing or dynamic) will be better accepted by the participants and will have a greater effect on lowering cortisol levels. (ii) Then, static breathing meditation was selected (as more effective for the given group), whose effect on lowering cortisol levels was tested on a larger group of participants (15). Results: Cortisol...

Vigilance behavior can aid in the detection of predators and may also play a role in observation of conspecifics, in food acquisition, and in the prevention of kleptoparasitism. However, in most occasions, vigilance is most important as an antipredator function. Generally, factors that increase the risk of predation also increase the amount of vigilance. We examined whether the reintroduction of the large predator, the wolf, in Yellowstone National Park (YNP) would influence coyote vigilance and foraging ecology. From December 1997 to July 2000, we collected 1743 h of coyote activity budgets. Coyote home ranges occurred within wolf territories (termed high-use or nonbuffer zone areas) and also between them in buffer zones. In high wolf use areas as well as when wolves were present, coyotes fed on carcasses much more; however, they increased the amount of vigilance and decreased rest to prevent predation. Wolf kills may provide a quick source of food and be energetically advantageous to coyotes; however, costs include increased vigilance, decreased rest, and a higher predation risk. Vigilance and avoidance behavioral responses to the reintroduction of large predators may ultimately be more common outcomes than actual killing by competing carnivores of prey. Keystone carnivore reintroductions have a variety of cascading effects throughout the ecosystem and can be driven by both numeric responses (trophic cascades) and behavioral responses ("behavioral cascades"). Behavioral cascades resulting from increased vigilance or spatial changes may lead ultimately to numeric changes and trophic cascades.

This thesis examines the regulation of women in public space in Liverpool between 1908 and 1957. It considers the complex relationship between the laws used to police solicitation, governmental debate about female prostitution and local purity campaigners’ concerns with the moral vulnerability of young, working-class, urban women. It is argued that the ways in which prostitution was understood and managed had an impact upon all women’s access to and use of public space, together with wider definitions of female morality and immorality. The thesis adds to historical understandings about the implications of prostitution regulation in the twentieth century, by moving away from London-focused histories to offer a detailed analysis of the ways in which national debates about vice were taken up at local level and with what consequences. I begin by exploring the problems with policing prostitution in the early-twentieth century and argue that increasing concern about the difficulty in differentiating prostitutes from ‘ordinary’ women provoked anxiety amongst law makers and government officials alike. It is argued that the debates canvassed by the 1927 Macmillan Committee indicate the degree to which moral codes about female sexuality informed official approaches to prostitution. The thesis considers the implications of these broad debates in Liverpool. Focusing on the work of the Liverpool Vigilance Association (LVA), it is proposed that fears about the moral threat of prostitution fuelled the organisation’s belief in the necessity of preventative patrol work centred on the moral surveillance of young, working-class women. This thesis shows that in interwar Liverpool, women’s movements were circumscribed first and foremost by their gender. Traditional, nineteenth-century ideas about women’s place within the domestic sphere created a sense among local purity campaigners that female morality was being threatened by women’s visibility in urban spaces. Other aspects of social status, such as class, race and employment experiences, heightened the interest of the LVA in targeting distinctive groups of women. The thesis demonstrates that in their efforts to regulate women’s movements through the city of Liverpool, local purists singled-out working-class and immigrant (especially Irish) women, as they believed them to be the most susceptible to corruption. This thesis draws on a wide range of archival sources, especially Home Office Records relating to the Public Places (Order) Bill and the establishment of the 1927 Macmillan Committee, as well as the LVA archive, in order to show how national and local policies on prostitution were both interdependent and distinct.

Im unter Ruhebedingungen abgeleiteten Elektroenzephalogramm (Ruhe-EEG) können Episoden niedergespannter EEG-Aktivität sowohl mit Schläfrigkeit, als auch mit geistiger Aktivität assoziiert sein. Aus diesem Grunde stellt niedergespannte EEG-Aktivität eine potentielle Fehlerquelle bei der Interpretation des Ruhe-EEGs dar. Wird niedergespannte EEG-Aktivität jedoch von für das Einschlafen charakteristischen, langsamen Augenbewegungen (Slow horizontal eye movements, SEM) begleitet, ist eine Assoziation mit geistiger Aktivität ausgeschlossen. Ziel dieser Dissertation ist die Untersuchung der Frage, ob niedergespannte EEG-Aktivität im Ruhe-EEG, welche von SEM begleitet wird (B1+), sich von solcher ohne begleitende SEM (B1-) hinsichtlich ihrer spektralen und räumlichen Zusammensetzung unterscheidet. Hierzu wurden 35 Ruhe-EEGs gesunder Probanden analysiert, welche jeweils mindestens 10s B1-, B1+ sowie 10s niedergespannter EEG-Aktivität während der Bearbeitung einer Kopfrechenaufgabe (calc) präsentierten. Unter Verwendung der Methode der standardized low resolution brain electromagnetic tomography (sLORETA) wurden für calc, B1- und B1+ die kortikalen Stromdichteverteilungen in vier verschiedenen, individuell angepassten Frequenzbändern berechnet. Die statistische Auswertung ergab signifikante Unterschiede zwischen B1- und B1+: Es zeigte bei B1- sowohl im Delta- als auch im Theta-Band eine geringere Aktivität im Bereich des Cingulums sowie benachbarten Teilen der Frontal-, Parietal- und Okzipiallappen. Zusätzlich zeigte sich eine erhöhte Aktivität im Frequenzbereich des Beta-Bandes in den Temporallappen für B1- verglichen mit B1+. Der Vergleich von calc mit B1+ erbrachte ähnliche Resultate. Die Befunde lassen eine Zugehörigkeit von B1- zu einem, verglichen mit B1+ höheren Vigilanzniveau vermuten und liefern Evidenz für die Einteilung niedergespannter Episoden im Ruhe-EEG in solche mit und ohne begleitende SEM.
