This paper proposes Lagrange multiplier (LM) based tests for the null hypothesis of no cointegration in panel data. The tests are general enough to allow for heteroskedastic and serially correlated errors, individual specific time trends, and a single structural break in both the intercept and slope of each regression, which may be located different dates for different individuals. The limiting di

Gränserna för vad som ska uppfattas som en muta är sällan enkla att dra. Det som juridiskt definieras som korrupt kan i vardagliga termer beskrivas som något klanderfritt – som provisioner, konsultuppdrag, gåvor, resor, bjudningar och liknande. Mutor kan ofta förklaras som närbesläktat med socialt umgänge eller gästfrihet. De kan också förklaras i termer av tacksamhet eller som sedvänja och kultur

A stochastic model based on a probability density function (PDF) approach was developed for the investigation of spark ignition (SI) engine knock conditions. The model is based on a two zone model, where the burned and unburned gases are described as stochastic reactors, and the movement of the turbulent flame front is expressed with a Wiebe function. Using a stochastic particle ensemble to repres

I denna vetenskapliga, existentiella biografi över drottning Victgoria av Sverige (1862-1930)möter vi en kvinnas religiösa och estetiska landskap, hennes sjukdom, och hennes kyrkliga och musikaliska initiativ, även i en frånvarande närvaro. Den aktiva resignation som blev hennes livshållning hämtade inspiration från så olika gestalter som Charles Kingsley, Gottfrid Billing, kardinal Hohenlohe och

An important feature in the Swedish avant-garde film culture of the 40s and 50s is the creation of a public sphere for cinephilia. At first this public sphere was an "Öffentlichkeit" in the sense of Negt and Kluge. No distinction was made between production, exhibition and distribution; film theoretical reading, film viewing, and film production were not separated, nor were the films categorized.

An essay on the use of empty space in graphic design, particularly in modern literature and sometimes as a visual sign of silence, illustrated from works of a.o. Caylus, Sterne, Greenaway, Mallarmé.

Language policy and planning (LPP) is one of the fastest growing sub-disciplines of applied linguistics. This book is the first volume that is exclusively devoted to research methods in language policy. As in other areas of applied linguistics, LPP scholars have drawn upon an array of research methods from a range of disciplines. This book is designed as a practical roadmap for those methods. Each

Popular Abstract in Swedish En insekts rörelsemönster i en värld av dofter Jag har videofilmat hur en marklevande insekt, Protaphorura armata, rör sig på en plan yta, hur de gör när de stöter på hinder, dofter från mat, artfränder och fiender. Jag har också använt matematiska modeller för att beskriva deras rörelsemönster. P. armata är en s.k. hoppstjärt men saknar förmågan att hoppa som flertaleMovement and dispersal are important determinants of the spatial distribution and persistence of animal populations in a heterogeneous environment. I studied the small-scale movement pattern of a soil-living insect, Protaphorura armata (Collembola) by using a video-equipment. I added chemical cues, food and conspecifics to their environment and evaluated the effects of external cues on the movemen
