- The aim of this study was threefold: (i) to clarify whether letter and category fluency tap different cognitive abilities; (ii) to make diagnostic comparisons and predictions using temporally resolved fluency data; (iii) to challenge and test the widely made assumption that 1-min sum scores are the fluency test measure of choice in the diagnosis of dementia. Scores from six 10-sec intervals of letter and category fluency tests were obtained from 240 participants including cognitive levels ranging from mild subjective cognitive complaints to Alzheimer's disease. Factor analysis revealed clearly separate factors corresponding to letter and category fluency. Category fluency was markedly impaired in Alzheimer's disease but not in Mild Cognitive Impairment. Only scores from relatively early intervals predicted Alzheimer's disease and Mild Cognitive Impairment. The conclusions are (i) letter and category fluency are different tests, category fluency being the best diagnostic predictor; (ii) it would be possible to administer category fluency tests only for 30 sec, because after this point the necessary differential diagnostic information about the patient's word fluency capacity has already been gathered.

- Supraspan verbal list learning is widely used to assess dementia and related cognitive disorders where declarative memory deficits are a major clinical sign. While the overall learning rate is important for diagnosis, serial position patterns may give insight into more specific memory processes in patients with cognitive impairment. This study explored these patterns in a memory clinic clientele. One hundred eighty three participants took the Rey Auditory-Verbal Learning Test (RAVLT). The major groups were patients with Alzheimer's disease (AD), Vascular Dementia (VD), Mild Cognitive Impairment (MCI), and Subjective Cognitive Impairment (SCI) as well as healthy controls (HC). Raw scores for the five trials and five serial partitions were factor analysed. Three memory factors were found and interpreted as Primacy, Recency, and Resistance to Interference. AD and MCI patients had impaired scores in all factors. SCI patients were significantly impaired in the Resistance to Interference factor, and in the Recency factor at the first trial. The main conclusion is that serial position data from word list testing reflect specific memory capacities which vary with levels of cognitive impairment.

The Compensatory Effect of Text-to-Speech Technology on Reading Comprehension and Reading Rate in Swedish Schoolchildren With Reading Disability : The Moderating Effect of Inattention and Hyperactivity Symptoms Differs by Grade Groups

Tidskriftsartikel (refereegranskat)abstract
- The purpose of this study was (i) to investigate if the compensatory effect of text-to-speech (TTS) technology on reading comprehension and reading rate in schoolchildren with reading disability is influenced by problems with inattention and hyperactivity and (ii) to examine whether a potentially moderating effect of such symptoms differ between grade groups. Participants (N = 49) were randomized into one of the two experimental conditions: Group A listened to a text with TTS, and Group B read the text themselves. The conditions were then switched. Inattention and hyperactivity symptoms were assessed with the Strengths and Difficulties Questionnaire (SDQ). Statistical analyses were performed both on the whole group and within-grade groups (Grades 3–5 and 6–9). Using TTS technology had a positive effect on reading rate for both grade groups, and this effect was not influenced by attention-deficit/hyperactivity disorder (ADHD) symptoms. As for reading comprehension, the two groups differed both with respect to the amount of improvement seen in the TTS condition and with respect to the moderating effect of ADHD symptoms. Reading with TTS improved reading comprehension significantly in the younger group, whereas no effect on reading comprehension was found in the older group. A higher score on the SDQ ADHD Scale was associated with less improvement in reading comprehension in the younger group and with greater improvement in reading comprehension in the older group. The results indicate that symptoms of inattention and hyperactivity, as well as the child’s grade level, are factors that should be taken into account when planning and introducing TTS technology.

Impaired verb fluency : a sign of mild cognitive impairment
- 2005

Tidskriftsartikel (refereegranskat)abstract
- We assessed verb fluency vs. noun and letter-based fluency in 199 subjects referred for cognitive complaints including Subjective Cognitive Impairment, Mild Cognitive Impairment, and Alzheimer's disease. ANCOVAs and factor analyses identified verb, noun, and letter-based fluency as distinct tasks. Verb fluency performance in Mild Cognitive Impairment differed significantly from Subjective Cognitive Impairment and Alzheimer's disease. Reduced verb fluency thus appears to be a linguistic marker for incipient dementia. One possibility is that the verb fluency deficit in Mild Cognitive Impairment results from degenerative processes known to occur in the parahippocampal region.

Does Investor Recognition Predict Excess Returns?

Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- We test Merton's (1987) hypothesis using individual level stockholdings of Swedish investors. Controlling for size and other factors, we find that lower levels of investor recognition lead to greater future excess returns. Positive (negative) changes in investor recognition are followed by lower (higher) excess returns. The effect of investor recognition is more pronounced for young firms. We demonstrate that investor recognition is conditionally priced.

Investor Recognition and the Long-Run Performance of Repurchases
- 2004
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Theory suggests that firms with lower investor recognition should provide investors with higher returns. Using U.S. data we document a strong negative relationship between changes in investor recognition and asset returns. We demonstrate that investor recognition is a priced factor in asset returns different from the traditional ones. Undertaking a repurchase significantly reduces the firm's investor recognition. Accounting for changes in investor recognition reduces the abnornlal performance of firms undertaking a repurchase by 1.4% over one year.

The Political Dimension of Place Branding
- 2015
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Place branding is commonly understood as the application of marketing and commercial ideas, strategies, measurements and logic to the realm of places such as cities, regions and nations. Nevertheless, place branding is also understood as the locus where political activities – imbued with political impact and political effects – appear and affect the soft and hard infrastructures of urban agglomeration and other spatial environments. In this regard, by performing an analysis that helps unpack the multiple characters and impacts of political structures and processes in relation to place branding activities, the present dissertation aims to offer a conceptualization of the political dimension of place branding. By drawing on the critical assessment of the academic literature on place branding and on a series of studies about the branding processes in the region of Romagna and in the Greater Stockholm, the present dissertation further specifies an alternative conceptual framework (i.e. ecological politics) that suggests how place branding should be seen an empirical and theoretical political apparatus that acts, in praxis, based on an emerging, multifaceted and spatio-temporal enfolding of politics. More specifically, the ecological politics of place branding is characterized by four main aspects: the unfolding of a biopolitical ecology around place-branding practices; the ideological appropriation of place-branding processes; the positioning through politicized actions between the interest groups; and finally place-branding as a process of policy-intervention. Finally, on more general level, the present dissertation, by recognizing the political activities and efforts of place branding as crucial elements to be analyzed, makes the case for a more explicit, complex and manifold political analysis of the political dimension of place branding, which allows attention to be given to the impact that branding processes, practices and activities have on cities, regions and nations

Mat, kärlek och metapraktik : En studie i vardagsmiddagskonsumtion bland ensamstående mödrar
- 2011
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The everyday dinner usually involves a number of different and sometimes conflicting ambitions that may include striving for self-fulfillment and striving to care for one’s family and society at large. To understand the consumption that occurs in connection with these ambitions, consumer researchers must understand the context surrounding the everyday dinner. In this dissertation theories of practice are utilized as a conceptual framework to emphasize the importance of context.Theories of practice have gained renewed interest within the field of consumption. Yet, Consumer Culture Theory (CCT) has neglected practice theories’ ability to operationalize the consumption context. The aim of this dissertation is to develop further CCT’s practice perspective to increase the understanding of the consumption context and thereby better understand consumption as a social and cultural phenomenon. An ethnographic approach is employed to identify what practices operate within a complex consumption situation such as the everyday dinner among single mothers; how these practices incorporate consumption in their strivings and how the different practices operating within the consumption situation interact with one another.This new approach comes to the conclusion that mothering, defined as a meta-practice, dominated the consumption situation and organized the other practices involved. A meta-practice is one with major influence over consumption and thus a type of practice consumption researchers should look for. Furthermore in Western society consumption situations, like the everyday dinner, seem to be especially important when it comes to anchoring meta-practices and thereby the social order. A preliminary characterization of the meta-practice is proposed as consisting of four different traits: I) its impact on the social order; II) its generalizability, density and superiority; III) its regulation and IV) its stability or slow change. However, more studies are necessary to explore these characteristics further.
