Recently, evidence for acoustic universals in vocal communication was found by demonstrating that humans can identify levels of arousal in vocalizations produced by species across three biological classes (Filippi et al., 2017). Here, we extend this work by testing whether two vocal learning species, humans and chickadees, can discriminate vocalizations of high and low arousal using operant discri

Purpose – The purpose of this paper is to explore, describe and categorise practices of managing product returns empirically in internet retailing.Design/methodology/approach – A multiple case study was conducted involving 12 e-commerce firms and 4 logistics service providers. An integrative data collection approach of semi-structured interviews, documentation and observations was used to gain com

This paper provides a framework by developing a conceptual model explaining how perceived return policy fairness influence consumer purchases intentions in an online context. By reviewing the literature in consumer return, signal and justice theory a conceptual model was developed. Consumer Return studies have historically been focused on reverse logistics but in the last decade moved focus toward

Den främsta orsaken till en ökad växthuseffekt anses idag bero på en högre koncentrationav koldioxid i atmosfären. Sedan den industriella revolutionen harmänniskan påverkat mängden koldioxid i atmosfären genom aktiviteter så somförbränning av fossila bränslen, avskogning, förändringar i markanvändning, samtcementproduktion. För att kunna motverka framtida klimatförändringar krävs enfördjupad kunskThis thesis focuses on the development and application of efficient mathematicaltools for estimating and modelling the exchange of carbon dioxide (CO2) between the Earth and its atmosphere; here referred to as the global CO2 surface flux.There are two main approaches for estimating the CO2 flux: Processed based(bottom-up) modelling and atmospheric inversion (top-down) modelling. Thefirst part of t

I augment transaction cost economics and the learning to contract perspective by outlining the effect of asymmetric contracting capabilities on contract design and governance structure. According to the learning to contract literature, parties in contractual relationships adopt a governance structure that economizes on transaction costs, and then over time learn to govern relationships in a more e

Parkinson's disease (PD) is a complex neurodegenerative disease, characterized by a progressive lossof dopaminergic neurons (DN) in the substantia nigra (SN) that innervate the striatum (ST) and pathologicalaccumulation of alpha-synuclein (αsyn) protein in aggregates called Lewy bodies (LB) and Lewy neurites(LN). As a complex disease, PD presents a genetically heterogeneous origin. Mutations in si

Water reuse can contribute as an important approach and practice to the reduction of the pressures on water resources lowering the demand for potable water for purposes that do not require water's high quality. However the greywater reuse has been rarely applied in Brazil. Therefore, the main objective of this study was to evaluate a greywater collection and treatment system from lavatories, showe

Separately collected urine is an attractive potential fertilizer because of its high nutrient content, low cost, and inherent linkage of urban wastewater management and peri-urban agriculture. Urine from waterless urinals was applied to corn and lettuce plants to examine the impact of urine application rates and frequency on plant growth and soil parameters. In both corn and lettuce experiments, u

Efterord till nyutgåva av Axel Wallengrens (Falstff, fakirs) ofullbordade bok "Tripp till världens ända". Inkluderar kort biografi över Wallengren samt redogörelse för manuskriptets tillkomst och tidigare publicering.

We detail here the convergence properties of a new model-independent imaging method, the Lévy expansion, that seems to play an important role in the analysis of the differential cross section of elastic hadron-hadron scattering. We demonstrate, how our earlier results concerning the Odderon effects in the differential cross-section of elastic proton-proton and proton-antiproton scattering as well

It is shown that Technicolor model can be formulated having vector-like interaction of Techniquarks with the Standard Model bosons and Dirac mass term. Oblique corrections values for the case agree with experimental restrictions. The model Lagrangian is based on σ−model scheme introducing Techni-meson and Techni-baryon states. Neutral component of a "triplet" of heavy scalar Techni-baryons can be
