Purpose: The purpose of this paper is to elaborate on how perspectives and assumptions embedded in the complexity paradigm contribute to make logistics management research better aligned with real-life logistics. This is necessary, due to increasing supply chain complexity caused by an increasing request for sustainable development (SD). Design/methodology/approach: The research is exploratory and
The minimum weighted edge dominating set problem (MWEDS) generalizes both the weighted vertex cover problem and the problem of covering the edges of graph by a minimum cost set of both vertices and edges. In this paper, we propose a meta heuristic approach based on genetic algorithm and local search to solve the MWEDS problem. Therefore, the proposed method is considered as a memetic search algori
Lawrence Summers produced a big upset within the economics profession when he revived Alvin Hansen’s theory of secular stagnation, which had been thought of as an old-Keynesian fallacy. While some economists like Brad DeLong and Paul Krugman instantly recognized Summers’s contribution, a large share of the economics profession remained skeptical at first. Whereas most New Keynesian models allow fo
Reactivity N - Own: Pyridine N-oxides can be used for the complete regio- and stereoselective synthesis of trans-substituted piperidines. The sequential addition of Grignard reagents and aldehydes or ketones to pyridine N-oxides yields a complete regio- and stereoselective trans 2,3- addition reaction in high yields, and the substituted 2,3-dihydropyridine N-oxide can be reduced to form 2,3-trans-
This article considers how the monetization of the street art world is affecting the ecosystem of expressions found in the street. It takes as a point of departure that a central quality of street art is its potential to turn public space into a site of exploration. What is meant by this, briefly, is that the presence of ephemeral street art can motivate people to explore their surroundings and pe
Total scattering and pair distribution function (PDF) analysis has created new insights that traditional powder diffraction methods have been unable to achieve in understanding the local structures of materials exhibiting disorder or complex nanostructures. Care must be taken in such analyses as subtle and discrete features in the PDF can easily be artefacts generated in the measurement process, w
The study of early watermills has, from its very beginning, concentrated on two issues: their diffusion (in time and space) and their technical construction. Very little interest has been devoted to the persons who built and managed them—the millwrights and the millers. This tendency has been even more manifest from the 1980s onward, when interest has focused more and more on the increasing number
The first measurement of the Υ(1S) elliptic flow coefficient (v2) is performed at forward rapidity (2.5
Introduction Anxiety problems have been recognized and discussed throughout the ages under various expressions and from different perspectives. Yet, their study as a specific form of childhood and adolescence psychopathology was largely neglected prior to the second half of the twentieth century. Only during the last 50 years have consistent efforts been made in psychology and psychiatry towards a
We present an up-to-date, comprehensive summary of the rates for all types of compact binary coalescence sources detectable by the initial and advanced versions of the ground-based gravitational-wave detectors LIGO and Virgo. Astrophysical estimates for compact-binary coalescence rates depend on a number of assumptions and unknown model parameters and are still uncertain. Themost confident among t
The cross-section average (CA) augmentation approach of Pesaran (A simple panel unit root test in presence of cross-section dependence. Journal of Applied Econometrics 2007; 22: 265–312) and Pesaran et al. (Panel unit root test in the presence of a multifactor error structure. Journal of Econometrics 2013; 175: 94–115), and the principal components-based panel analysis of non-stationarity in idios
The phylogeny of the subfamily Xanthorioideae (Teloschistaceae) is re-analysed based on ITS, LSU and mtSSU sequences, including a new set of specimens representing 31 genera, of which five are proposed as new: Golubkovia, Igneoplaca, Langeottia, Scythioria and Verrucoplaca. Two new species, Ovealmbornia volkmarwirthii from South Africa and Gondwania sejongensis from Antarctica are described, illus
In this study, we examine individual patent holders and the fate of their inventions. A unique database consisting of over 800 private individuals who have obtained decision rights over a new technology in Sweden is used to analyse how opportunity and individual level characteristics are related to the likelihood that patented inventions are commercialised in a new or existing small firm. Our find
New research guidelines for the diagnosis of Alzheimer's disease (AD) include biomarker evidence of amyloid-β (Aβ) and tau pathology. The aim of this study was to investigate what proportion of AD patients diagnosed in clinical routine in Sweden that had an AD-indicative cerebrospinal fluid (CSF) biomarker profile.
Glycan utilization plays a key role in modulating the composition of the gut microbiota, but molecular insight into oligosaccharide uptake by this microbial community is lacking. Arabinoxylo-oligosaccharides (AXOS) are abundant in the diet, and are selectively fermented by probiotic bifidobacteria in the colon. Here we show how selectivity for AXOS uptake is established by the probiotic strain Bif
A reduced finite element model for determining the maximum principal stress of a glass pane subjected to dynamic impact load is developed and compared to a full dynamic finite element model. The reduced model is based on the Rayleigh-Ritz method. The Ritz vectors used are determined by simple static load-cases. The model is applicable to centrically and eccentrically applied impact and to glass of
