Research on returns policies is scarce and inconclusive. This study is a first attempt to empirically analyze and describe the effects of returns policies on consumer behavior and the moderating effects of the policies on profitability. The method involves analyzing the transactional data of a Swedish online fashion retailer. The results of the regression analyses show that with a lenient returns

PurposeThe aim of the study is to understand how meaning is assigned to online searching by viewing it as a mundane, yet often invisible, activity of everyday life and an integrated part of various social practices.Design/methodology/approachSearching is investigated with a sociomaterial approach with a starting point in information searching as entangled across practices and material arrangements

Dermatofibrosarcoma protuberans (DFSP) is a cutaneous tumour of borderline malignancy, the cytogenetic features of which include the translocation t(17;22)(q22;q13) or, more commonly, supernumerary ring chromosomes containing material from 17q22 and 22q13. These rearrangements result in the COL1A1/PDGFB fusion gene. Here, we describe a case of DFSP displaying a ring chromosome 5 together with a la

Researchers apply Neural Networks widely in model prediction and data mining because of their remarkable approximation ability. This study uses a prediction model based on the Elman and NARX Neural Network and a back-propagation algorithm for forecasting call volumes in call centers. The results can help determine the optimal number of agents necessary to reduce waiting time for customers, enablin

We demonstrate a wet chemical method to selectively etch InP segments within InAs/InP heterostructure nanowires based on a photo-assisted HAc/HBr solution etching process. We successfully etched InP segments ranging from 60 nm down to about 10 nm in size.

Color vision in birds is mediated by four types of cone photoreceptors whose maximal sensitivities (λmax) are evenly spaced across the light spectrum. In the course of avian evolution, the λmax of the most shortwave-sensitive cone, SWS1, has switched between violet (λmax > 400 nm) and ultraviolet (λmax < 380 nm) multiple times. This shift of the SWS1 opsin is accompanied by a corresponding short-w

This paper presents simulation results for a sliding-IF SiGe E-band transmitter circuit for the 81-86 GHz E-band. The circuit was designed in a SiGe process with fT = 200 GHz and uses a supply of 1.5 V. The low supply voltage eliminates the need for a dedicated transmitter voltage regulator. The carrier generation is based on a 28 GHz quadrature voltage oscillator (QVCO). Upconversion to 84 GHz is

In this paper we describe our approach to robotic skill representation and a prototypical implementation of a programming-by-demonstration approach that allows users to generate skills and robot program primitives for later re- finement and re-use. We intend to evaluate the applicability of this approach to high-level programming in a user study, which we also explain.

Dikotomin mellan den urbanisering och landsbygd har de senaste åren blivit starkare. Denna rapport sammanfattar samhällsvetenskaplig forskning om samt utforskar empiriskt hur denna dikotomi har konstruerats socialt och kulturellt. Flera sociala trender identifieras och diskuteras.

ABINIT is a package whose main program allows one to find the total energy, charge density, electronic structure and many other properties of systems made of electrons and nuclei, (molecules and periodic solids) within Density Functional Theory (DFT), Many-Body Perturbation Theory (GW approximation and Bethe-Salpeter equation) and Dynamical Mean Field Theory (DMFT). ABINIT also allows to optimize

Realism as a theory of science, in the view of the author of this paper, provides elegant solutions to several puzzles and dilemmas, not only in philosophy, but also to some of the most fundamental theorerical and methodological problems in social science. This paper introduces scien­tific realism, and presents one way of applying it to social science.

Physical therapy and social interactions between the stroke patient and health-care professionals or relatives facilitate the process of recovery and promote improvement of lost neurological function after stroke. These observations can be mimicked in an experimental setting by multimodal stimulation provided in the concept of enriched environment. The enriched environment is a housing condition f

GABA (γ-aminobutyric acid) is the major inhibitory neurotransmitter in the central nervous system, and changes in GABAergic neurotransmission modulate the activity of neuronal networks. Gephyrin is a scaffold protein responsible for the traffic and synaptic anchoring of GABAA receptors (GABAAR); therefore, changes in gephyrin expression and oligomerization may affect the activity of GABAergic syna

Physical therapy and social interactions between the stroke patient and health care professionals or relatives facilitate the process of recovery and promote the improvement of neurological function after stroke. These observations can be mimicked in the experimental setting with the concept of enriched environment. The enriched environment is a housing condition for rodents combining social inter
