Stimulated emission of particles by 1+1 dimensional black holes

The stimulated emission of massless bosons by a relativistic and the CGHS black hole are studied for real and complex scalar fields. The radiations induced by one-particle and thermal states are considered and their thermal properties investigated near the horizon. These exhibit both thermal and non-thermal properties for the two black-hole models.Comment: 29 pages, Latex (run 3 times

Aurel Kolnai

Aurel Kolnai (1900–1973) is best known for his political and moral writings, but he also chiefly contributed to the phenomenology of the emotions. In a series of papers devoted to hostile and aversive emotions and, in particular, to disgust, haughty pride, fear, and hatred (Kolnai 1929, 1931, 1935 and 1998) Kolnai presents his most comprehensive views on the affective life and its ethical significance. Scattered discussions on the emotions can also be found in an early paper written on Scheler and under the influence of psychoanalysis (1925), in his dissertation Der ethische Wert und die Wirklichkeit (Ethical Value and Reality) (1927), which is his first phenomenological writing, and in later papers “On the Concept of the Interesting” (1964) and “The Concept of Hierarchy” (1971). This chapter is divided into four sections. The first reconstructs Kolnai’s general approach to the emotions as embedded within the larger context of early phenomenology. Sections 2–4 present Kolnai’s analyses of hostile emotions by focusing on disgust, haughty pride, and hatred

Else Voigtländer

Else Voigtländer (1882–1946) provided one of the first substantial contributions to the phenomenology of the emotions. Her writings, which unfortunately have remained mostly unexplored, anticipate many of the issues that would become major focal points for later phenomenologists working on the topic. Within the phenomenological movement, Voigtländer was one of the first to study phenomena such as Ressentiment, inauthentic feelings and erotic love. In her book Vom Selbstgefühl (On the Feeling of Self-Worth) (1910), she undertakes an exhaustive study of the feelings of self-worth as part of a more ambitious project of elaborating a study of character. Further discussions on feelings, emotions and their relation to values can be found in a series of papers devoted to character traits, political emotions, erotic love and the psychology of sentiments (Voigtländer 1920, 1923, 1928 and 1933). This chapter is divided into four sections. The first presents Voigtländer’s notion of feelings of self-worth (Selbstgefühle). The remaining sections are devoted to her analyses of inauthentic feelings, Ressentiment and other negative attitudes, and erotic love, respectivel

Geiger and Wollheim on Expressive Properties and Expressive Perception

The aim of this paper is to reconstruct Geiger’s realist and Wollheim’s projectionist accounts on expressive properties and expressive perception by considering them within the larger contexts from which they emerged, by using as far as possible a common language and by focusing on the questions of the nature of expressive properties and of how we grasp them. My aim is to show that it is possible to put into dialogue phenomenological and Anglo-American aesthetics and that this dialogue might lead to new insights about how we engage with art

Mud Creek Urban Nonpoint Source Demonstration

Northwest Arkansas is the seventh fastest developing area in the nation. The conversion of rolling pastureland into paved city streets, parking lots, and buildings within this rapidly urbanizing region is reducing infiltration and intensifying stormwater runoff. In the city of Fayetteville alone, the population increased from 42,099 to 58,163 between 1990 and 1999, moving the city across the population threshold which will require the Phase II Stormwater Permit process. Approximately half of Fayetteville is included in the Illinois River Watershed, which has been identified as the third highest priority watershed in need of restoration in the state of Arkansas. Mud Creek, an urban tributary to the Illinois River, receives half of the treated effluent from the Fayetteville municipal wastewater treatment plant in addition to capturing residential and commercial runoff in Northeast Fayetteville. Pollutants including sediment, nutrients, bacteria and chemicals can be channeled off residential lawns, parking lots, and construction sites, through stormdrains, and into area water resources. For these reasons, the Mud Creek sub-basin of the Illinois River was the focus of an EPA 319(h) grant-funded project focusing on urban NPS prevention education. The Mud Creek Project was the first of it’s kind in Arkansas to target urban audiences, promoting their role and responsibility in improving and protecting the water quality in an urbanizing watershed
