Population Decline and Plague in late medieval Norway

Norwegian scholars have engaged in considerable research over the last half century in an attempt to assess the impact of the Black Plague of 1349 on population and society in Norway. Evidence has been put forward relating the incidence of plague to a continuance of population decline over the two centuries following its initial introduction. Estimates of population decline in Norway between 1350 and 1550 indicate a reduction by as much as 65 % . Two directions of study have emerged, one concentrating on land abandonment known as the "Odegard Project." The other is represented by the recent works of Ole Jorgen Benedictow presenting epidemiological and osteo-archaeological research. An examination of the available literature raises questions concerning the degree to which plague, and its recurrence, directly affected population decline in Norway during the Late Middle Ages. While evidence of the virulence of the plague and the degree of farm abandonment is compelling, a direct relationship to population decline may not be as great as implied by the research. Other explanatory factors, especially social and économie responses to plague, have been given limited attention.Les chercheurs norvégiens ont beaucoup travaillé durant la seconde partie du XIXe siècle sur les répercussions de la Grande Peste sur la population et société norvégiennes. On a établi avec certitude la relation entre l'incidence de la peste et le déclin continuel de la population durant les deux siècles qui ont suivi son apparition. Le déclin de la population norvégienne entre 1350 et 1550 fait état d'une baisse qui atteint 65 %. Deux orientations de recherche sont apparues. L'une centrée sur l'abandon des terres et connue sous l'appellation "Projet Odegard". L'autre est représentée par les travaux récents de Ole Jorgen Benedictow sur la recherche epidemiologique et archéologique. La lecture de ces travaux soulève la question de savoir dans quelle mesure la peste et ses réapparitions ont directement affecté la diminution de la population en Norvège à la fin du Moyen Age. Si le rapport entre la virulence de la peste et l'importance des abandons de fermes est évident, en revanche une relation directe avec la baisse de la population n'apparaît pas de manière aussi nette dans ces recherches. D'autres facteurs explicatifs, spécialement sociaux et économiques, ont été insuffisamment observés.Brothen James A. Population Decline and Plague in late medieval Norway.

Examining Procrastination across Multiple Goal Stages: A Longitudinal Study of Temporal Motivation Theory

Procrastination is among the most common of motivational failures, putting off despite expecting to be worse off. We examine this dynamic phenomenon in a detailed and realistic longitudinal design (Study 1) as well as in a large correlational data set (N = 7400; Study 2). The results are largely consistent with temporal motivation theory. People’s pacing style reflects a hyperbolic curve, with the steepness of the curve predicted by self-reported procrastination. Procrastination is related to intention-action gaps, but not intentions. Procrastinators are susceptible to proximity of temptation and to the temporal separation between their intention and the planned act; the more distal, the greater the gap. Critical self-regulatory skills in explaining procrastination are attention control, energy regulation and automaticity, accounting for 74% of the variance. Future research using this design is recommended, as it provides an almost ideal blend of realism and detailed longitudinal assessment
