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

Urban planning is the most relevant decision-making process affecting urban regulating ecosystem services. However, a clear understanding of the effects of planning decisions on both the supply and demand of urban regulating ecosystem services is still lacking. To support planners in enhancing urban regulating ecosystem services, there is a need to understand what variables are at stake and how ch

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-

Question: How does reproductive timing in annual social insects evolve under intraspecific exploitation competition and in response to a changing environment? The latter includes shifts in resource abundance, mortality, season length, and resource peak timing, factors often associated with climate change. Background: Climate and land use are changing. Evolutionary ecology must learn to predict how

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

Biogeochemical silicon (Si) cycling in coastal systems is highly influenced by anthropogenic perturbations in recent decades. Here, we present a systematic study on the distribution of stable Si isotopes of dissolved silicate (δ30SiDSi) in a highly eutrophic coastal system, the Baltic Sea. Besides the well-known processes, diatom production and dissolution regulating δ30SiDSi values in the water c

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

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

From the catalytic, semiconducting, and optical properties of zinc oxide (ZnO) numerous potential applications emerge. For the physical and chemical properties of the surface, under-coordinated atoms often play an important role, necessitating systematic studies of their influence. Here we study the vicinal ZnO(10 1 ¯ 4) surface, rich in under-coordinated sites, using a combination of several expe

Responding to today's often transboundary emergencies, frequently characterized by unclear root causes and indistinct responsibilities as well as multiple actors, will require that responding actors come together to meet societal needs and solve problems arising in relation to those needs. In collective problem solving, representing the problem is crucial, especially in emergency situations, where

The Danish religious landscape has been significantly transformed, especially during the last three decades. This transformation is marked by the shift from near religious hegemony towards a much more diverse religious population. Originally, the Danish Lutheran state church was closely intertwined with the governmental administration of the country after the reformation in Denmark of 1536 and the
