1. 6. Some Cases of Kudla’s Modularity Conjecture for Unitary Shimura Varieties

   Författare :Jiacheng Xia; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; special cycles; Eisenstein series; spherical designs; central L-values; unitary Shimura varieties; Jacobi forms; rational points; generating functions; the circle method; Kudla s modularity conjecture; theta series; Rankin--Selberg method;

   Sammanfattning : A common theme of the thesis is the interplay of symmetry and rigidity, which is a general phenomenon in mathematics. Symmetry is a notion related to the degree to which an object remains unchanged under transformations, and rigidity is a notion that in terms of physics can be thought of as a lack of freedom, which leads to stronger properties of an object than we normally expect.

3. 7. Essays on Microeconometrics and Immigrant Assimilation

   Författare :Alpaslan Akay; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Average marginal effect; Marginal effect of the average individual; Employment and earnings assimilation; Quasi-fixed effects approach; Initial value problem; Dynamic censored random-effects model; Monte Carlo experiment; Heckman’s approximation; Simple method of Wooldridge; Dynamic random-effects sample-selection model; wage-curve method;

   Sammanfattning : Paper I. Asymptotic bias reduction for a conditional marginal effects estimator in sam- ple selection models. In this article we discuss the di¤erences between the average marginal effect and the mar- ginal effect of the average individual in sample selection models, estimated by the Heck- man procedure.

4. 8. Measurement of alignment between standards and assessment

   Författare :Gunilla Näsström; Widar Henriksson; Peter Nyström; Jan-Olof Lindström; Astrid Pettersson; Umeå universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; alignment; standards; assessment; Bloom s revised taxonomy; the Angoff method; the borderline-group method; usefulness; validity; Other processing assembly; Övrig bearbetning sammanfogning;

   Sammanfattning : Many educational systems of today are standards-based and aim at for alignment, i.e. consistency, among the components of the educational system: standards, teaching and assessment. To conclude whether the alignment is sufficiently high, analyses with a useful model are needed. LÄS MER

5. 9. Analytical method development in liquid chromatography- mass spectrometry based metabolomics

   Författare :Ida Erngren; Mikael Hedeland; Curt Pettersson; Torbjörn Arvidsson; Gérard Hopfgartner; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Analytical pharmaceutical chemistry; metabolomics; liquid chromatography; mass spectrometry; hydrophilic interaction liquid chromatography; Analytical Pharmaceutical Chemistry; Analytisk farmaceutisk kemi;

   Sammanfattning : Metabolomics is the analytical field which aims at analyzing all small molecules, metabolites, in a biological system simultaneously. Currently no analytical methods are able to capture the entire metabolome, therefore, the analytical methods are often developed to be as general as possible. LÄS MER

7. 10. Essays on Mergers and Acquisitions and Event Studies

   Författare :Mohammad Irani; Lars Nordén; Rickard Sandberg; Neslihan Ozkan; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; mergers and acquisitions; event study; prediction; payment method; conditional CAPM; time-varying parameters; structural change methodology; variance; covariance; företagsekonomi; Business Administration;

   Sammanfattning : This dissertation consists of three studies on the anticipation of mergers and acquisitions (M&As) and its impact on takeover event studies. Article I investigates whether the market can anticipate both takeovers and their payment forms prior to their announcement dates. LÄS MER
