Technological impacts on market attitudes and behaviors

Technology has had a profound effect on twentieth century society and is increasingly changing the nature of the way we live our lives in the twenty first century, particularly, but not solely, through innovations in digital and social media marketing. As media and other technologies change, the question arising concerns how these changes impact on consumers’ attitudes and behaviors, and consequently on their lives. In this special edition, nine papers are presented, outlining cutting-edge research exploring how changing technologies affect consumer attitudes, emotions and behaviors in a variety of country settings and industries. In this introductory editorial, the papers are outlined in further detail, with a brief exposition of their contribution

Assent for children's participation in research is incoherent and wrong

When children are considered for participation in research, British and international guidelines suggest that they should provide assent in addition to their parents' consent. However, examination of these guidelines shows there is confusion regarding the concept of assent. Furthermore, the need for assent may cause problems. The guidelines should be revised: the parents of incompetent children should consent for them and competent children should consent on their own behalf

Death and best interests: a response to the legal challenge

In an earlier paper I argued that we do not have an objective conception of best interests and that this is a particular problem because the courts describe that they use an ‘…objective approach or test. That test is the best interests of the patient’ when choosing for children. I further argued that there was no obvious way in which we could hope to develop an objective notion of best interests. As well as this, I argued that a best-interest-based approach was a particular problem around the time of death of some children. A response from a legal perspective argued that, while there is not a clear conception of objective best interests, the courts have a well-described approach to finding a child's objective best interests. In this paper, I argue that without clear agreement on an objective conception of best interests, the courts are unable to locate an objective sense of best interests and that the solutions do not solve the problems that were identified in the initial paper ‘Death and best interests’

Asymmetry in Leader Image Effects and the Implications for Leadership Positioning in the 2010 British General Election

Using national survey data on voters' perceptions of party leaders during the 2010 British general election campaign, we use logistic regression analysis to explore the association between specific image attributes and overall satisfaction for each leader. We find attribute-satisfaction relationships differ in some respects between the three main party leaders, demonstrating that leader image effects are not symmetrical across leaders. We find evidence that negative perceptions have more powerful effects on satisfaction than positive ones, implying that parties should seek to determine a leader's image attribute perceptions measured against the public's expectations of them on the same dimensions. The positions that campaigners ought then to choose are those that will have the most beneficial effect in encouraging voting behaviour for each particular leader or discouraging voting behaviour for an opponent

Influence and interference in foreign elections

The use of influence or interference activities by one country to change the tide of elections in another has recently gained prominence due to alleged Russian influence in the 2016 US presidential election and the 2017 French presidential election. In this article, Paul Baines and Nigel Jones chart the evolution of influence and interference in foreign elections. With the rise of its modern digital form, they consider whether it is acceptable as a norm in international relations, or a violation

Regulation of synaptic connectivity: levels of fasciclin II influence synaptic growth in the Drosophila CNS

Much of our understanding of synaptogenesis comes from studies that deal with the development of the neuromuscular junction (NMJ). Although well studied, it is not clear how far the NMJ represents an adequate model for the formation of synapses within the CNS. Here we investigate the role of Fasciclin II (Fas II) in the development of synapses between identified motor neurons and cholinergic interneurons in the CNS of Drosophila. Fas II is a neural cell adhesion molecule homolog that is involved in both target selection and synaptic plasticity at the NMJ in Drosophila. In this study, we show that levels of Fas II are critical determinants of synapse formation and growth in the CNS. The initial establishment of synaptic contacts between these identified neurons is seemingly independent of Fas II. The subsequent proliferation of these synaptic connections that occurs postembryonically is, in contrast, significantly retarded by the absence of Fas II. Although the initial formation of synaptic connectivity between these neurons is seemingly independent of Fas II, we show that their formation is, nevertheless, significantly affected by manipulations that alter the relative balance of Fas II in the presynaptic and postsynaptic neurons. Increasing expression of Fas II in either the presynaptic or postsynaptic neurons, during embryogenesis, is sufficient to disrupt the normal level of synaptic connectivity that occurs between these neurons. This effect of Fas II is isoform specific and, moreover, phenocopies the disruption to synaptic connectivity observed previously after tetanus toxin light chain-dependent blockade of evoked synaptic vesicle release in these neurons

Automatic estimation of flux distributions of astrophysical source populations

In astrophysics a common goal is to infer the flux distribution of populations of scientifically interesting objects such as pulsars or supernovae. In practice, inference for the flux distribution is often conducted using the cumulative distribution of the number of sources detected at a given sensitivity. The resulting "$\log(N>S)$-$\log (S)$" relationship can be used to compare and evaluate theoretical models for source populations and their evolution. Under restrictive assumptions the relationship should be linear. In practice, however, when simple theoretical models fail, it is common for astrophysicists to use prespecified piecewise linear models. This paper proposes a methodology for estimating both the number and locations of "breakpoints" in astrophysical source populations that extends beyond existing work in this field. An important component of the proposed methodology is a new interwoven EM algorithm that computes parameter estimates. It is shown that in simple settings such estimates are asymptotically consistent despite the complex nature of the parameter space. Through simulation studies it is demonstrated that the proposed methodology is capable of accurately detecting structural breaks in a variety of parameter configurations. This paper concludes with an application of our methodology to the Chandra Deep Field North (CDFN) data set.Comment: Published in at http://dx.doi.org/10.1214/14-AOAS750 the Annals of Applied Statistics (http://www.imstat.org/aoas/) by the Institute of Mathematical Statistics (http://www.imstat.org

The persuasiveness of guilt appeals over time: Pathways to delayed compliance

Past research on guilt-elicitation in marketing does not examine how the communications' effects might persist over time, when there is a gap between advertising at time 1 and the time of choice consideration at time 2. This study explores the processes leading to delayed compliance through guilt-based communications. Guilt elicitation enhances transportation into the message, driving message compliance through the effect of transportation. Transportation explains the effects recorded several days after campaign exposure. The influence of transportation is mediated by two pathways: increases in anticipated guilt and perceived consumer effectiveness. The message type moderates the relevance of different pathways in explaining persuasiveness. Appeals delivered through a text and image message (rather than text only) are more effective in driving compliance and shape reactions via guilt anticipation. The study raises important implications for research on the use of guilt appeals and the design of more effective messages based on this emotion

Evolving forms of manufacturing strategy development:evidence and implications

This paper outlines, using evidence from several case studies, the use of alternative forms of manufacturing strategy processes. Our investigation shows that the manufacturing strategy development practices of manufacturers are evolving in many directions; we found several alternatives to the formal top-down planning process. Manufacturers use one or more of the following alternatives with or without the top-down manufacturing strategy process: a coherent pattern of actions; manufacturing/process improvement programs; or the pursuit of core manufacturing capabilities. It appears that the various manufacturing strategy development processes may be tied to the strategic role of manufacturing in a company. This paper offers a framework that captures the relationship between the strategic role of manufacturing and the process of manufacturing strategy development. An in-depth case from a UK company illustrates the evolving forms of manufacturing strategy development processes
