The marketing firm and co‐creation: The case of co‐creation by LEGO

This article discusses the marketer and customer co‐creation process within the context of bilateral contingencies. Bilateral contingencies occur when the marketers' behavior is reinforced (and/or punished) by the customers' behavior, whereas the behavior of the customers is reinforced (and/or punished) by the marketers' actions. Using the example of the LEGO community, we discuss how the marketers in the organization can respond to behaviors resulting from co‐creational customer– customer exchanges. This paper fills the knowledge gap by presenting a behavior analysis framework (theory of the marketing firm) for the empirical measurement of the co‐creation process.The marketing firm and co‐creation: The case of co‐creation by LEGOacceptedVersio

Vaccine refusal: a preliminary interdisciplinary investigation

Many people who generally receive standard recommended inoculations refuse to partake of COVID-19 vaccines, preventatives that are effective, safe, and life-saving amidst the current pandemic. Our quest is to understand this puzzling and dangerous phenomenon, as it exists among US and UK citizens, whom in other respects would be regarded as quite regular. We will discuss Vaccine Refusal compared with two better understood phenomena: addiction, and akrasia, along with the related matters of human action, intention, agency, will, and identity. Vaccine Refusal, we will argue, appears to be rewarded by “informational reinforcement” leading to heightened arousal, along with increases in self-esteem resulting from “bucking the trend,” asserting one's “superior” understanding, and “tribal identity” in acting against social norms. These factors provide an overall reward amounting to satisfaction that outweighs the well-known consequences of COVID-19 infections. Our investigations will also lead us to a pair of epistemological hypotheses about two subtypes of the Vaccine Refusers under consideration here

Force-matched embedded-atom method potential for niobium

Large-scale simulations of plastic deformation and phase transformations in alloys require reliable classical interatomic potentials. We construct an embedded-atom method potential for niobium as the first step in alloy potential development. Optimization of the potential parameters to a well-converged set of density-functional theory (DFT) forces, energies, and stresses produces a reliable and transferable potential for molecular dynamics simulations. The potential accurately describes properties related to the fitting data, and also produces excellent results for quantities outside the fitting range. Structural and elastic properties, defect energetics, and thermal behavior compare well with DFT results and experimental data, e.g., DFT surface energies are reproduced with less than 4% error, generalized stacking-fault energies differ from DFT values by less than 15%, and the melting temperature is within 2% of the experimental value.Comment: 17 pages, 13 figures, 7 table

Preserved monocyte-derived dendritic cell differentiation and maturation in the presence of HIV-2 envelope

© 2012 Mary Ann Liebert, Inc. publishers. All rights reserved, USA and worldwide.Dendritic cells (DCs) are fundamental for the initiation of immune responses and are important players in AIDS immunopathogenesis. Impairment of DC function may result from bystander effects of HIV-1 envelope proteins independently of direct HIV-1 infection. HIV-2 envelope proteins are thought to interact with a broader range of receptors than those of HIV-1, and have been shown to have T cell immunosuppressive properties mediated by monocytes. The effects of HIV-2 envelope on DC differentiation and maturation were investigated. The modulatory properties of the HIV-2 envelope on DC generated from monocytes were assessed using both recombinant proteins (HIV-2(ROD) and HIV-2(ALI)) and whole chemically inactivated virus (aldrithiol-2-treated HIV-2(ROD)). DC phenotype was assessed by flow cytometry and DC function by their ability to stimulate allogeneic T cells and to produce cytokines. We demonstrate that HIV-2 Env had no effects upon DC differentiation and maturation despite its broad receptor usage and ability to modulate monocyte function. It is plausible to speculate that a reduced ability of the HIV-2 Env to impair myeloid DC function could represent a contributory factor to the relatively benign course of HIV-2 disease.This work was supported by grants from “Fundação para a Ciência e a Tecnologia” (FCT) and by “Programa Operacional Ciência e Inovação 2010” (POCI2010) to AES.

Does excessive use of smartphones and apps make us more impulsive? An approach from behavioural economics

Purpose Problematic smartphone use has been associated with negative effects in work and school environments. This study proposes the application of a behavioural economics perspective to establish whether heavy smartphone users show a tendency to devalue the consequences of their behaviour in the long term. To address this proposition, the study sought to establish how an objective measurement of usage time of smartphones and apps might help to predict, firstly, participants’ choice behaviour and, secondly, their perceived dependence levels. Design/methodology/approach An objective measurement of the usage time of smartphones and apps was conducted over four weeks (N = 560 data points), and a computer-based intertemporal choice task and the Spanish version of the Smartphone Addiction Inventory (SPAI) were applied. The participants were twenty undergraduate college students. Findings Although the usage time of devices and apps failed to predict the choice behaviour, a correlation was found between the total usage time of smartphones and WhatsApp and Facebook apps and users’ dependence level. On the other hand, dependence had a positive effect on the average selection of the impulsive choice. Originality/value This paper proposes the application of a behavioural economics perspective to explore the relationship between objectively measured usage time of smartphone and apps, choice behaviours in an intertemporal task and users’ perceived dependence levels. This allows us to consider an alternative to the traditional psychiatric approach in an environment of increasing access to and use of mobile digital platforms

The theory of the marketing firm

The theory of the marketing firm locates the rationale of the modern business enterprise that lies in its responding profitably to the imperatives of marketing orientation. Economic theories of the firm generally fail to recognize these imperatives, enhanced consumer choice and sophistication, which entail marketing orientation as the rationale of the firm. The paper propose a competence theory of the firm as a metacontingency and examines the bilateral contingencies by which firms link to their consumerates, which indicate their capacities for customer orientation. The marketing firm emerges as a means of encapsulating entrepreneurship, economizing on transaction costs, and enabling the management of marketing specialization

Gag-specific CD4+ T-cell frequency is inversely correlated with proviral load and directly correlated with immune activation in infection with human immunodeficiency virus type 2 (HIV-2) but not HIV-1

Copyright © 2008, American Society for Microbiology. All Rights Reserved.Human immunodeficiency virus type 2 (HIV-2) infection, unlike HIV-1 infection, is normally characterized by low rates of CD4 depletion and low-to-undetectable viremia. We found that the frequency of Gag-specific CD4(+) T cells featured positive correlations with the expression of markers of CD4 activation and a negative correlation with peripheral blood mononuclear cell-associated proviral load in infection with HIV-2, in contrast with HIV-1. Moreover, HIV-2-infected individuals exhibited a greater ability to respond to HIV-1 Gag peptides (heterologous responses). Our data suggest a potential link between HIV-2-specific CD4 responses, immune activation, and viral control, which may in turn relate to the better prognosis associated with HIV-2 infection.This work was supported by grants from Fundação para a Ciência e a Tecnologia (FCT) and by Programa Operacional Ciência e Inovação 2010 (POCI 2010) to A.E.S.

The marketing firm and co‐creation: An empirical study of marketer and customer's co‐creation process

This study empirically investigates the marketer and customer's co‐creation process within the context of the marketing firm. Based on principles from bilateral contingencies, findings from a conjoint study (n = 98) indicate that utilitarian and informational reinforcing consequences from the marketer have a stronger impact on customers' co‐creation behavior relative to informational reinforcing consequences from other customers. Consequently, analyzing the impact of important reinforcing contingencies through the lens of bilateral contingencies expands our understanding of how and why co‐creation outcomes might occur. Also, a good co‐creation process may increase the business companies' research and intelligence and, as a consequence, strengthen their competitiveness.The marketing firm and co‐creation: An empirical study of marketer and customer's co‐creation processacceptedVersio

SMEs' purchasing habits : A procurement maturity model for stakeholders

Although micro companies overpower the small and medium enterprise (SME) segment, generalizations are often with medium size companies, and therefore, there are many unknowns, especially when it comes to its buying behavior. Conformist studies and industry practices assume SMEs to be “normative” or “conservative” buyers; however, this hypothesis is untested. This article aims to scrutinize the reality, and proposes a unified model that rejects pre-containerization in buying behavior typologies, as well as selectiveness in terms of audience type, whether it is corporate, SME, or consumer. While replacing researchers’ perceptions with the audience’s, the model yields actual knowledge that can lead to audience’s beliefs in lieu of the opposite, which is used to mislead stakeholders. The study shows that SMEs also buy like individuals and spend in a similar way to consumers’, including not only “normative” and “conservative” but also “negligent” and “impulse” zones. From the research-implications perspective, future studies by behaviorists can explore why SMEs purchase in this way. Marketers may benefit from the finding that SMEs buy like individuals. In addition, SMEs may want to be conscious of their purchasing habits, and—utilizing the newly introduced “risk score” frontier—policymakers should assess the consequences of these habits at the macro level
