Culture and Identity in Organization Studies

This chapter deals with culture and identity in management studies. An interest in culture and identity can be understood as an interest in the symbolic side of the organization that deals with meaning, interpretation, symbols and action (rather than behavior). The symbolic side of enterprise has always been present in organization studies; since the early 1980s, however, this has predominantly be

Laughter in stories of crime and tragedy : The importance of humor for marginalized populations

Humor is essential to social life, but it is often overlooked in the study of crime and other social problems. We introduce and make use of humor theory, emphasizing the theories of superiority and relief. Based on interviews with incarcerated men, we demonstrate how humor is used to criticize authorities, for self-aggrandizement, and to alleviate the pain of tragic experiences. Funny remarks and

Friction Compensation Based on LuGre Model

We consider a tracking problem for mechanical systems. It is assumed that feedback controller is designed neglecting some disturbances, which could be approximately modeled by a dynamic LuGre friction model. We are interested to derive an additive observer-based compensator to annihilate or reduce the influence of such a disturbance. We exploit a recently suggested approach for observer design for

The asymptotic distribution of the isotonic regression estimator over a general countable pre-ordered set

We study the isotonic regression estimator over a general countable pre-ordered set. We obtain the limiting distribution of the estimator and study its properties. It is proved that, under some general assumptions, the limiting distribution of the isotonized estimator is given by the concatenation of the separate isotonic regressions of the certain subvectors of an unrestrecred estimator’s asympto

The Swedish Fiscal Framework – The Most Successful One in the EU?

This paper discusses the history and future of the Swedish fiscal framework. First, we claim that the fiscal framework has contributed to a sharp decline in the debt-to-GDP ratio, from one of the highest to one of the lowest in the European Union. Next, we focus on the future. Despite its success, we argue that the framework is unsustainable. Running large surpluses over the long run is not a stea

Bandwidth-Constrained Capacity Bounds on MIMO Antennas

The optimal spectral efficiency of MIMO antennas in Rayleigh and ideal channels are investigated when bandwidth requirements are placed on the antenna. By posing the problem as a convex optimization problem restricted by the port Q-factor a semi-analytical expression is formed for its solution. The antennas are simulated by method of moments and the solution is formulated both for structures fed b

The coexistence of humans and algorithmic machines

Machine Learning (ML) applications shape, and are shaped by, human values. In the last decade classificatory models have become the most widely applied type of ML. However, since the invention of Generative Adverserial Networks (GANs) in 2014, the field of generative ML is likely to become equally prolific in the years to come. GANs can generate convincing fakes of video footage, pictures, graphic

Testing and Modelling of Electrical Traction Machines : Performance Characterisation with Measurements from Transient Operation

This thesis presents methods to derive and model the performance characteristics of interior permanent magnet machines – a machine type which is commonly used for propulsion of electrical vehicles. The thesis divides the performance characteristics into three subcategories: The electromagnetic properties, the loss profile and the thermal behaviour of the machines. One separate characterisation metThis thesis presents methods to derive and model the performance characteristics of interior permanent magnet machines – a machine type which is commonly used for propulsion of electrical vehicles.

The aerobic diagenesis of Mesoproterozoic organic matter

The Xiamaling Formation in the North China Block contains a well-preserved 1400 Ma sedimentary sequence with a low degree of thermal maturity. Previous studies have confirmed the dynamic and complex nature of this evolving marine setting, including the existence of an oxygen-minimum zone, using multi-proxy approaches, including iron speciation, trace metal dynamics, and organic geochemistry. Here,

Resursanvändning och samverkan mellan skola och socialtjänst vid barnavårdsutredningar : En modell för beräkningar av tid, kostnader och samverkan

Under hösten 2017 och våren 2018 genomförde innovationsenheten PART – Preventivt arbete tillsammans– och Institutionen för service management och tjänstevetenskap vid Lunds universitet ett utvecklingsarbete,med syftet att ta fram en modell för att öka kunskapen om resursanvändning i barnavårdsutredningar. Måletmed den framtagna modellen är att göra det möjligt att kartlägga arbetsuppgifter och tid
