Robustifying principal component analysis with spatial sign vectors

2012

In this paper, we apply orthogonally equivariant spatial sign covariance matrices as well as their affine equivariant counterparts in principal component analysis. The influence functions and asymptotic covariance matrices of eigenvectors based on robust covariance estimators are derived in order to compare the robustness and efficiency properties. We show in particular that the estimators that use pairwise differences of the observed data have very good efficiency properties, providing practical robust alternatives to classical sample covariance matrix based methods. peerReviewed

Lutheran Clergy in an Orthodox Empire. The Apppointment of Pastors in the Russo-Swedish Borderland in the 18th Century

2015

Abstract The history of the parishioners’ right to participate in and influence the choice of local clergy in Sweden and Finland can be taken back as far as the late Medieval Times. The procedures for electing clergymen are described in historiography as a specifically Nordic feature and as creating the basis of local self-government. In this article the features of local self-government are studied in a context where the scope for action was being modified. The focus is on the parishioners’ possibilities and willingness to influence the appointment of pastors in the Lutheran parishes of the Russo-Swedish borderlands in the 18th century. At the same time, this article will offer the first c…

The Joint Distribution Criterion and the Distance Tests for Selective Probabilistic Causality

2010

A general definition and a criterion (a necessary and sufficient condition) are formulated for an arbitrary set of external factors to selectively influence a corresponding set of random entities (generalized random variables, with values in arbitrary observation spaces), jointly distributed at every treatment (a set of factor values containing precisely one value of each factor). The random entities are selectively influenced by the corresponding factors if and only if the following condition, called the joint distribution criterion, is satisfied : there is a jointly distributed set of random entities, one entity for every value of every factor, such that every subset of this set that corr…

When Social Media Influencers Go Political: An Exploratory Analysis on the Emergence of Political Topics Among Finnish Influencers

2022

Social media influencers are often understood as non-political actors who, due to the impact they exert on their followers’ purchase decisions and brand attitudes, play an important role in marketing and branding. In recent years, various influencers have addressed political issues during important political events such as elections. This political aspect of social media influencing has not received much scholarly interest thus far. In one of the first exploratory studies on the topic, we surveyed over one hundred Finnish influencers and investigated the degree to which they engaged with political topics. Our results show that political topics are commonly brought up among Finnish influence…

Multiple forms of stakeholder interaction in environmental management: business arguments regarding differences in stakeholder relationships

2010

This study describes and interprets differences in stakeholder interaction as rhetorically constructed in environmental reports and in interviews with environmental managers. It also interprets the role of the natural environment among stakeholders, and discusses how that role is justified or not justified. The study focuses in a business perspective on stakeholder interaction in environmental management. Characteristically, stakeholder studies of environmental management have concentrated on stakeholder influence or the creation of stakeholder management models. In contrast to those, the present study identifies different types of stakeholder relationships: power-based, collaborative, conf…

The Process of Selecting Influencers for Marketing Purposes in an Organisation

2023

Influencer marketing practices are growing on social media channels, while the usage of other mass-media channels is decreasing, prompting organisations to search for new tools with which to communicate efficiently with their target audiences. Influencers can affect purchase intentions if the audience identifies with them. For a successful collaboration with an influencer, an organisation needs to ensure that the brand fit is suitable, as the audience will become suspicious if the paid collaboration is too apparent. In addition, an organisation can ask an influencer to perform many roles during the collaboration. The objectives of this study, therefore, are to discover how organisations ens…

Social media influencer: a new hybrid professionalism in the age of platform capitalism?

2023

International audience; Chapter 13 Social media influencer: a new hybrid professionalism in the age of platform capitalism? by P. Sedda and O. Husson, analyses the way social media influencers, acting in the context of communities of practice, participate in redefining professionalism and professional practices in marketing and communications fields while promoting social values or advocating for a cause of public interest. Using a methodological approach based on interviews and ethnographic observation, the study considers the influencer as a specific case of “hybrid professionalism” (Noordegraaf 2007) in which quantitative performance criteria, prescribed by platforms, are combined with c…

The Role of Social Media Influencers in Public Health Communication: Case COVID-19 Pandemic

2022

During public health crises, public organizations face a variety of strategic communication challenges, and the outbreak of the COVID-19 pandemic in 2020 is an extreme example. In Finland, the Prime Minister’s Office initiated a communication campaign that utilized social media influencers to communicate timely instructions regarding the pandemic. However, it is uncertain how social media influencers adapt to briefings of public organizations given that they typically work with brands that align with their own interests and expertise, which rarely is epidemiology. We use the two-step flow of communication model and social influence theory to analyze research data that consisted of 96 Instag…
