Entrepreneurship in the Age of Big Data: A Researcher's Guide to Data Mining, Inference and Prediction

The bottleneck of Big Data today is the analysis of large amounts of information, including data mining, inference and prediction. Entrepreneurship researchers who want to take advantage of Big Data, need tools and workflows to find important trends and patterns within massive data sets, and understand "what the data tell us." Here, we apply gradient boosting to big, register-based data, and estab

Three-year outcome of rivastigmine treatment in Alzheimer's disease in a routine clinical setting.

Objectives: Long-term, placebo-controlled studies of cholinesterase inhibitors (ChEIs) in Alzheimer’s disease (AD) are not permitted for ethical reasons. Therefore, the advancement of knowledge on longitudinal outcomes in different domains warrants well-designed naturalistic studies. The aim of this study was to explore the 3-year effectiveness of rivastigmine treatment. Methods: The Swedish Alzhe

Fields of Green and Gold : Territorial hunger, rural planning, and the political ecologies of high-end golf

Fields of Green and Gold är en multipel fallstudie som analyserar placeringen och etableringen av två storskaliga, berömda och påkostade golfanläggningar för att därigenom undersöka den exklusiva golfens politiska ekologi. De fall som studeras är Bro Hof Slott Golf Club i Upplands-Bro - som öppnade 2007 - och Trump International Golf Links Scotland i Aberdeenshire - som öppnade 2012. Att analyseraFields of Green and Gold is a multiple case study analysing the placing and establishment of two large-scale, high-profile, upmarket golf developments with the aim of exploring a political ecology of high-end golf. The cases studied are Bro Hof Slott Golf Club in Upplands-Bro, opened in 2007, and Trump International Golf Links Scotland in Aberdeenshire, opened in 2012. Reading these two cases toge

Multilayered wideband absorbers for oblique angle of incidence

Design procedures of Jaumann and circuit analog absorbers are mostly formulated for normal angle of incidence. Only a few design methods considering oblique angle of incidence are published. The published methods are restricted to single resistive layer circuit analog absorbers or multilayered Jaumann absorbers with low permittivity spacers. General design procedures are developed in this paper fo

From Partnership to Resistance: Unions and Organisational Learning at Ericsson Infocom

In recognising that much mainstream literature on organisational learning is overwhelmingly managerial, this paper explores learning as an appropriate framework for studying organisations at the level of sub-systems or subcultures. It is thus argued that there is an interesting agenda to be pursued by the critical researcher on seeing organisational learning as a means of analysing both co-operati

Multi-level coding/modulation using LDPC convolutional codes

In this paper, we propose a novel multilevel coding scheme that employs low-density parity-check convolutional (LDPCC) codes. A combined decoding/ demodulation scheme is also considered. Unlike previous work on multilevel coding, the proposed scheme employs a single code with some structure that allows it to benet from the use of multilevel mapping. The proposed scheme can be seen as a form of bit

Assessing interleaver suitability for turbo codes

The two major purposes of the interleaver in a turbo coding scheme are, firstly, to improve the weight distribution of the turbo code, and, secondly, to make the performance of iterative decoding as close to maximum likelihood as possible. Both these purposes should be considered when ranking and designing interleavers for turbo codes. In lack of a measure of how well the second purpose is carried
