Decomposing the Afternoon Effect: An Empirical Investigation of Sequential Train Ticket Auctions
- 2015
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- The afternoon effect, i.e., that prices in a sequence of auctions with identical items are decreasing with the order in which the auctions are terminated, is a frequently observed phenomenon in empirical auction studies. Using an unsurpassed amount of data from sequential online train ticket auctions, we investigate two hitherto unexplored dimensions inherent in sequential auctions, namely, the timing of auction ends and the presentation order of the auctions in a sequence. We find that both these dimensions are important for price formation in sequential auctions, but even when controlling for them, a sizable afternoon effect remains.

- This paper investigates two hitherto unexplored dimensions inherent in online sequential auctions, namely, how the time elapsed between the end of an auction and the end of the next one and the order of presentation on the website affect prices. Using a state-of-the-art-dataset on train-ticket auctions with a particular institutional design feature that enables a causal interpretation of these dimensions, it is demonstrated that both dimensions have a significant impact on price formation in sequential auctions.

The Difference Approach to Narrative Fiction : A Recurring Critique of Narratology and Its Implications for the Study of Novels and Short Stories
- 2019
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The aim of this thesis is to advance the critical examination of narratology, or the study of storytelling. I analyze four versions of a critique of the dominant theory of narrative fiction in narratology and discuss this critique’s methodological implications. The critics, Sylvie Patron, Lars-Åke Skalin, Richard Walsh, and the proponents of unnatural narratology have, I suggest, similar understandings of narratology’s handling of works like novels and short stories as well as similar alternative approaches. I situate the critique among relevant theories of fiction and salient aspects of narratology, and conclude that the most radical critics have a difference approach to narrative fiction. This means treating this literary practice as following another rule system for creating meaning than other kinds of storytelling. These critics seem to base their reasoning on their readerly intuitions about how novels and short stories function; yet their approach also lends itself to, for instance, discussions on how such works afford life visions or worldviews. In contrast to this approach, I describe narratology, in the critics’ view, as having a sameness approach that treats narrative fiction as a subtype of “narrative” in the sense of the communication of events by a narrator.The three opening articles of the thesis comprise a metadiscussion of the critique. I here describe, in part with Greger Andersson, the critics’ ideas, characterize the critique as a whole, and speculate about why it has had no apparent effect on narratology. The two latter articles utilize the difference approach in analyses of Angela Carter’s “The Loves of Lady Purple” and Sara Stridsberg’s Drömfakulteten (The Faculty of Dreams) while discussing narratological concepts and issues. Future studies might continue this discussion or inquire further about, for example, the relations between different narrative practices or what role different intuitions about narrative fiction play in descriptions and analyses.

Plasma-assisted molecular beam epitaxy of ZnO on in-situ grown GaN/4H-SiC buffer layers

Tidskriftsartikel (refereegranskat)abstract
- Plasma-assisted molecular beam epitaxy (MBE) was used to grow ZnO (0001) layers on GaN(0001)/4H-SiC buffer layers deposited in the same growth chamber equipped with both N- and O-plasma sources. The GaN buffer layers were grown immediately before initiating the growth of ZnO. Using a substrate temperature of 440 degrees C-445 degrees C and an O-2 flow rate of 2.0-2.5 sccm, we obtained ZnO layers with smooth surfaces having a root-mean-square roughness of 0.3 nm and a peak-to-valley distance of 3 nm shown by AFM. The FWHM for X-ray rocking curves recorded across the ZnO(0002) and ZnO(10 (1) over bar5) reflections were 200 and 950 arcsec, respectively. These values showed that the mosaicity (tilt and twist) of the ZnO film was comparable to corresponding values of the underlying GaN buffer. It was found that a substrate temperature > 450 degrees C and a high Zn-flux always resulted in a rough ZnO surface morphology. Reciprocal space maps showed that the in-plane relaxation of the GaN and ZnO layers was 82.3% and 73.0%, respectively and the relaxation occurred abruptly during the growth. Room-temperature Hall-effect measurements showed that the layers were intrinsically n-type with an electron concentration of 10(19) cm(-3) and a Hall mobility of 50 cm(2).V-1.s(-1).

- Svenskarnas globala utsläpp från köttkonsumtion och flygresor motsvarar hälften av de totala utsläppen på hemmaplan. I vår rapport till Naturvårdsverket föreslår vi tydliga styrmedel – som nya skatter – för att begränsa konsumtionen på dessa områden, skriver 14 miljö- och energiforskare.

Sameness versus Difference in Narratology : Two Approaches to Narrative Fiction

Tidskriftsartikel (refereegranskat)abstract
- In this article we examine the critical proposition that common versions of narratology do not provide an accurate description of narrative fiction and analyze why this critique has mostly been disregarded by narratology. The theoreticians we refer to-Sylvie Patron, Richard Walsh, and Lars-Ake Skalin-do not accept the notion that narrative fiction should be understood in terms of non-fictional narratives. We label their position a "difference approach" in contrast to a putative "sameness approach." We find their "difference" arguments convincing and therefore ask why they have had no apparent effect on narratology. As we discuss misreadings that the criticized approach to narrative fiction could be expected to generate and arguments that refute the existence of such misreadings, as well as suggested readings of narrative fiction by Liesbeth Korthals Altes, James Phelan, David Herman, and Gerard Genette, we make the claim, referring to Phelan's rhetorical narratology, that sameness narratology is often presented as a theory but in fact used and defended as a method or toolbox. Our suggestion is that it would be better to rework the theory of narrative fiction commonly adopted by narratologists so that the theoretical assertions become congruent with the analytical practice and with the intuitions about narrative fiction that the analytical practice implies. We thus support the difference approach.

Orexin A Phosphorylates the gamma-Aminobutyric Acid Type A Receptor beta(2) Subunit on a Serine Residue and Changes the Surface Expression of the Receptor in SH-SY5Y Cells Exposed to Propofol

Tidskriftsartikel (refereegranskat)abstract
- Propofol activates the gamma-aminobutyric acid type A receptor (GABA(A)R) and causes a reversible neurite retraction, leaving a thin, thread-like structure behind; it also reverses the transport of vesicles in rat cortical neurons. The awakening peptide orexin A (OA) inhibits this retraction via phospholipase D (PLD) and protein kinase CE (PKCE). The human SH-SY5Y cells express both GABA(A)Rs and orexin 1 and 2 receptors. These cells are used to examine the interaction between OA and the GABAAR. The effects of OA are studied with flow cytometry and immunoblotting. This study shows that OA stimulates phosphorylation on the serine residues of the GABA(A)R beta(2) subunit and that the phosphorylation is caused by the activation of PLD and PKCE. OA administration followed by propofol reduces the cell surface expression of the GABA(A)R, whereas propofol stimulation before OA increases the surface expression. The GABA(A)R beta(2) subunit is important for receptor recirculation, and the effect of OA on propofol-stimulated cells may be due to a disturbed recirculation of the GABA(A)R.
