The childhood-onset neuropsychiatric background to adulthood psychopathic traits and personality disorders.
- 2005
-
In: Comprehensive psychiatry. - : Elsevier BV. - 0010-440X. ; 46:2, s. 111-6
-
Journal article (peer-reviewed)abstract
- Childhood conduct disorder (CD) and adult psychopathic traits according to the Psychopathy Checklist Revised (PCL-R) were the closest psychiatric covariates to repeated violent crimes and aggression among offenders under forensic psychiatric investigation in Sweden. As psychopathy is not included in the present psychiatric diagnostic systems, we compared total and factor PCL-R scores to Axis I disorders, including childhood-onset neuropsychiatric disorders, and to Axis II personality disorders, to establish the convergence of psychopathic traits with other psychiatric diagnoses, and to identify possible unique features. Psychopathic traits were positively correlated with bipolar mood disorder and negatively with unipolar depression. The total PCL-R scores as well as the Factor 2 (unemotionality) and Factor 3 (behavioral dyscontrol) scores were significantly correlated with attention-deficit/hyperactivity disorder, Asperger's syndrome/high-functioning autistic traits, CD, substance abuse, and the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition Cluster B personality disorders. The interpersonal Factor 1 showed none of these correlations and may capture features that are specific to psychopathy, distinguishing core psychopathy from other diagnostic definitions.

When communication challenges brand associations : a framework for understanding consumer responses to brand image incongruity
- 2006
-
In: Journal of Consumer Behaviour. - : Wiley. - 1479-1838 .- 1472-0817. ; 5:1, s. 32-42
-
Journal article (other academic/artistic)abstract
- In this conceptual paper, the authors review literature on how consumers react when a piece of brand communication is incongruent with established brand associations. Although brand experts typically criticize such brand image incongruity, it is a fact that companies do communicate in a way that challenges existing associations, for example in advertising or when launching brand extensions. The article integrates previous work-which has been scattered across several poorly connected domains-into a coherent framework. The authors propose effects of brand image incongruity on consumers' processing and evaluation. They also identify marketing implications and avenues for future research. The propositions imply opportunities for brand management, thus suggesting the need for a balanced view on brand image incongruity.

MASQOT : a method for cDNA microarray spot quality control.
- 2005
-
In: BMC Bioinformatics. - : Springer Science and Business Media LLC. - 1471-2105. ; 6, s. 250-
-
Journal article (peer-reviewed)abstract
- BackgroundcDNA microarray technology has emerged as a major player in the parallel detection of biomolecules, but still suffers from fundamental technical problems. Identifying and removing unreliable data is crucial to prevent the risk of receiving illusive analysis results. Visual assessment of spot quality is still a common procedure, despite the time-consuming work of manually inspecting spots in the range of hundreds of thousands or more.ResultsA novel methodology for cDNA microarray spot quality control is outlined. Multivariate discriminant analysis was used to assess spot quality based on existing and novel descriptors. The presented methodology displays high reproducibility and was found superior in identifying unreliable data compared to other evaluated methodologies.ConclusionThe proposed methodology for cDNA microarray spot quality control generates non-discrete values of spot quality which can be utilized as weights in subsequent analysis procedures as well as to discard spots of undesired quality using the suggested threshold values. The MASQOT approach provides a consistent assessment of spot quality and can be considered an alternative to the labor-intensive manual quality assessment process.

Age at onset of substance abuse: a crucial covariate of psychopathic traits and aggression in adult offenders.
- 2007
-
In: Psychiatry research. - : Elsevier BV. - 0165-1781 .- 1872-7123. ; 153:2, s. 195-8
-
Journal article (peer-reviewed)abstract
- To examine age at onset of substance abuse in relation to other factors of relevance to criminal behavior, we compared Life History of Aggression (LHA) scores, traits of psychopathy according to the Psychopathy Checklist--Revised (PCL-R), and violent recidivism in 100 violent offenders with early (before the age of 18) versus late onset of abuse or dependence. Of 56 subjects with a history of alcohol and/or drug abuse, an early onset was ascertained in 31. The duration of abuse did not correlate with the LHA and PCL-R scores or with violent recidivism, but the age at onset correlated strongly with all these factors and also remained their strongest correlate in multivariate models including childhood-onset attention deficit/hyperactivity disorder, conduct disorder, and drug abuse as covariates. Strong mathematical associations with aggression, psychopathy, and recidivism pointed to age at onset of substance abuse as a marker of possible complications that require preventive social, educational and medical measures.

Effects of ad-brand incongruency
- 2005
-
In: Journal of Current Issues and Research in Advertising. - : Informa UK Limited. - 2164-7313 .- 1064-1734. ; 27:2, s. 1-12
-
Journal article (peer-reviewed)abstract
- In this article, we add to the research on information incongruency in advertising with two studies of ad-brand incongruency. In the first study, subjects were exposed to either an ad that was congruent with the brand schema or an ad that was incongruent with the brand schema. Comparisons showed that the incongruent ad produced a lower ad attitude and ad credibility, but a higher brand attitude and more sophisticated processing of brand-related information. In the second study, the results of ad-brand incongruency on ad attitude, ad credibility and brand attitude were tested at one and two ad exposures. Furthermore, the impact of two moderating variables were tested: need for cognition (NFC), and attitude toward advertising. Theoretical and managerial implications from the two studies are discussed.

Dirt! : an interpretive study of negative opinions about a brand extension
- 2006
-
In: European Advances in Consumer Research. - : Association for Consumer Research. - 9780915552559 ; 7, s. 92-96
-
Journal article (other academic/artistic)abstract
- How can researchers and managers understand the notions and feelings behind unfavorable responses to a brand extension? Using a sociocultural perspective on purity and impurity (Douglas 1966), this paper explores the usefulness of thinking about negative opinions in terms of reactions to dirt. The metaphor informs an interpretation of negative comments in an internet discussion forum, on the introduction of a new car model from Porsche. Conceptions of dirt as disturbing and upsetting; risky and dangerous; and immoral and blameworthy, are employed to develop new insights into the intersection between brands, brand extensions, and consumers.

- 2007
-
In: Journal of Brand Management. - : Springer Science and Business Media LLC. - 1479-1803 .- 1350-231X. ; 14:3, s. 223-231
-
Journal article (other academic/artistic)abstract
- The possibility to assess brand strategies based on their financial consequences is attractive to managers and researchers alike. This conceptual article discusses financial assessment of brand extension proposals within companies. An integrated framework synthesises key questions and arguments in theoretically informed valuation, in order to support managerial decision-making. It highlights the link between brand equity considerations and financial evaluation, to acknowledge the role of brand extension as an investment in business development. The ideal role of financial assessment in the practice and research of brand extension is discussed.

Tensions of extensions : adverse effects of brand extension within consumer relationships
- 2008
-
Doctoral thesis (other academic/artistic)abstract
- Imagine how you would react if you learned that your favorite singer was recording new music in a style far from that which you have come to love. Perhaps you would disapprove. Then you might react like many Porsche consumers did when they learned that “their” brand would start producing sports utility vehicles. They are not without peers. In fact, how would you respond if a favored brand would launch, say, a chain of coffee shops? Some people would resist such an idea. These scenarios illustrate how strong consumer-brand bonds may complicate attempts to extend brands into new businesses. The research presented in the thesis explores this connection, towards a better understanding of the stakes facing both companies and consumers. It is an inquiry into tensions of extensions. The thesis comprises four published studies. Three explore how consumers with close ties to a brand react to brand extension. They acknowledge that consumers who come close to a brand potentially become stakeholders with opinions on efforts to change the products and marketing of that brand. They suggest that the implications of combining brand extension and strong consumer bonds can be substantial. The fourth study considers how the financial implications in particular can be analyzed and communicated within organizations. The findings show how brand extension can be an important event in a longer relationship with core consumers. This perspective is easily obscured when concentrating only on the perceptions of “the average consumer”. The thesis highlights symbolic and experiential aspects. It offers a closer look at such things as consumer identity, emotional reactions, and expression of criticism, and the findings should inform communication strategies and decision-making related to brand extensions.

Upsetting brand extensions : an enquiry into current customers' inclination to spread negative word of mouth
- 2008
-
In: Journal of Brand Management. - : Palgrave Macmillan. - 1479-1803 .- 1350-231X. ; 15:4, s. 258-271
-
Journal article (peer-reviewed)abstract
- The opinions of current customers are important when introducing new products through brand extension. This paper deals with the potential for negative word of mouth and empirically investigates the inclination of current customers to criticise a brand extension. The study identifies antecedents to this inclination and highlights the importance of anger. Implications for brand management are offered and encourage broad analysis of extension initiatives that could become targets of negative word of mouth.
