Forskningsöversikt (refereegranskat)abstract
- While consumer engagement (CE) in the context of artificially intelligent (AI-based) technologies (e.g., chatbots, smart products, voice assistants, or autonomous cars) is gaining traction, the themes characterizing this emerging, interdisciplinary corpus of work remain indeterminate, exposing an important literature-based gap. Addressing this gap, we conduct a systematic review of 89 studies using the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) approach to synthesize the AI-based CE literature. Our review yields three major themes of AI-based CE, including (i) Increasingly accurate service provision through AI-based CE; (ii) Capacity of AI-based CE to (co)create consumer-perceived value, and (iii) AI-based CE's reduced consumer effort in their task execution. We also develop a conceptual model that proposes the AI-based CE antecedents of personal, technological, interactional, social, and situational factors, and the AI-based CE consequences of consumer-based, firm-based, and human-AI collaboration outcomes. We conclude by offering pertinent implications for theory development (e.g., by offering future research questions derived from the proposed themes of AI-based CE) and practice (e.g., by reducing consumer-perceived costs of their brand/firm interactions).

Bokkapitel (populärvet., debatt m.m.)abstract
- Utgångspunkten i vårt forskningsprojekt Kreativa och entreprenöriella utkanter (Creative and entrepreneurial edges) är att geografer och andra akademiker kanske i alltför hög utsträckning har fokuserat på städer, urbana miljöer och tätbebyggda infrastrukturer. Detta för att förklara fenomen som relaterar till kreativa processer och aktiviteter. Framförallt har man lyft fram den närhet och interaktion som kan uppstå i städer och som kan ge fördelar i processer som har att göra med nya idéer och kreativitet. Motsatt har forskningen inte i tillräcklig utsträckning uppmärksammat vare sig de aktiviteter som de facto sker i periferin, samt de fördelar som existerar i mer perifera lokaliseringar. Det finns således anledning att ifrågasätta en förenklad och binär uppdelning. I det forskningsprojekt vi arbetar med är utgångspunkten att även om centrum är viktigt för allehanda kreativa processer så kan vi inte bortse från perifera miljöers roll och positiva effekter på kreativa processer. Syftet är således att undersöka idén om att kreativitet och entreprenörskap i utkanten och på perifera platser är betydelsefull och hållbar och att vi bör förhålla oss till idén om att outsiders ofta omformulerar våra frågeställningar och föreställningar och förändrar vårt sätt att se. För att nyansera förståelsen kring myter som är relaterade till konstnärskap, kreativa processer och perifera platser har vi valt att empiriskt fokusera på konstnärer i Värmland och Skogen mellan oss. Vi antar ett relationellt perspektiv på platser och processer. Det ger oss utrymme att utmana en ortodox uppdelning mellan centrum och periferi och på så vis frångå synen på dessa som en dualism, ett antingen-eller. Vi hävdar att det att vara perifer varken betyder att man är isolerad eller hänvisad till en lägre grad av professionellt arbete eller sämre kreativa möjligheter. Snarare bör vi se centrum-periferi som ett kontinuum där ett nätverk av aktörer (individer, organisationer eller objekt) agerar på olika avstånd. Denna studie visar att ekonomiska faktorer och balansen mellan arbete och privatliv är två väsentliga orsaker till att konstnärer väljer att bosätta sig och vara aktiva i periferin. Samtidigt omfamnar konstnärerna de kreativa möjligheter som uppstår av att befinna sig i utkanten och de skapar aktivt lokala och externa nätverksrelationer och plattformar. För konstnärer och kulturarbetare är en binär rumslig indelning således inte en relevant utgångspunkt. Istället behövs en mer nyanserad förståelse av relationella geografier som stödjer både landsbygden som kreativ plats och de individuella konstnärernas kreativa karriärer. I synnerhet ifrågasätter vi antagandet om att urban kreativitet är kollektiv och att landsbygdens kreativitet är individuell och skulle sakna fördelarna med närhet och agglomeration. Det är just i arbetet med att skapa infrastruktur för konst och kreativitet på landsbygden som det kollektiva är centralt. Där bidrar professionaliteten både i det konstnärliga arbetet i sig och i tillgången till professionella nätverk till att flera konstnärer kan dra nytta av detta och utveckla sitt konstnärskap. Vi hävdar således att dessa konstnärer inte väljer mellan den sociala staden och den isolerade landsbygden. De kombinerar fördelarna med de bägge genom translokala processer och nätverk.

- Objective Objective measurement of audibility (verification) using bone conduction devices (BCDs) has long remained an elusive problem for BCDs. For air conduction hearing aids there are well-defined and often used objective methods, and the aim of this study is to develop an objective method for BCDs. Design In a novel setup for audibility measurements of bone-anchored hearing aid (BAHA) attached via a soft band, we used a skin microphone (SM) on the forehead measuring in-situ sound field thresholds, maximum power output (MPO) and international speech test signal (ISTS) responses. Study sample Five normal-hearing persons. Result Using the electrical output of SM it was possible to objectively measure the audibility of a skin drive BCD, presented as an eSPL-o-gram showing thresholds, MPO and ISTS response. Normalised eSPL-o-gram was verified against corresponding FL-o-grams (corresponding force levels from skull simulator and artificial mastoid (AM)). Conclusion The proposed method with the SM can be used for objective measurements of the audibility of any BCDs based on thresholds, MPO and speech response allowing for direct comparisons of hearing and BCD output on the same graph using an eSPL-o-gram. After normalisation to hearing thresholds, the audibility can be assessed without the need for complicated calibration procedures.

A barrier to sustainable transports? : Path dependence and the Swedish tax deduction for commuting
- 2023

- We explore the decisions in Parliament about the Swedish tax deduction for commuting since the 1980s. The aim is to explain the continuity of the tax regulation despite several attempts from motions in Parliament and public investigations to reform it towards environmental goals, e.g., reduced emissions of CO2. When reforms have been proposed, the political majority in Parliament has regardless of political colour voted against and retreated to the original motives for the tax deduction; economic growth and the enlargement of regional labour markets. The interests of Swedish mass motorisation succeeded in finding the arguments to slow down reforms and at the same time reinforce the path dependency by adding new legitimacy to the regulation. If the attempts to reform the tax deduction had been part of a broader reform of the transport sector and the tax system, they might have succeeded in breaking with the old path.

- 2023
-

Tidskriftsartikel (refereegranskat)abstract
- Introduction: The aim of this study was to develop a clinical test for body sounds' hypersensitivity in superior canal dehiscence syndrome (SCDS). Method: Case-control study, 20 patients affected by SCDS and body sounds' hypersensitivity and 20 control matched subjects tested with a new test called ankle audiometry (AA). The AA consisted of a psychoacoustic hearing test in which the stimulus was substituted by a controlled bone vibration at 125, 250, 500, and 750 Hz, delivered at the medial malleolus by a steel spring-attached bone transducer prototype B250. For each subject, it was defined an index side (the other being non-index), the one with major symptoms in cases or best threshold for each tested frequency in controls. In 3 patients, the AA was measured before and after SCDS surgery. Results: The AA thresholds for index side were significantly lower in SCDS patients (115.6 ± 10.5 dB force level [FL]) than in control subjects (126.4 ± 8.56 dB FL). In particular, the largest difference was observed at 250 Hz (-16.5 dB). AA thresholds in patients were significantly lower at index side in comparison with non-index side (124.2 ± 11.4 dB FL). The response obtained with 250 Hz stimuli outperformed the other frequencies, in terms of diagnostic accuracy for SCDS. At specific thresholds' levels (120 dB FL), AA showed relevant sensitivity (90%) and specificity (80%) for SCDS. AA did not significantly correlate to other clinical markers of SCDS such as the bone and air conducted hearing thresholds and the vestibular evoked myogenic potentials. The AA thresholds were significantly modified by surgical intervention, passing from 119.2 ± 9.7 to 130.4 ± 9.4 dB FL in 3 patients, following their relief in body sounds' hypersensitivity. Conclusion: AA showed interesting diagnostic features in SCDS with significantly lower hearing thresholds in SCDS patients when compared to healthy matched subjects. Moreover, AA could identify the affected or more affected side in SCDS patients, with a significant threshold elevation after SCDS surgery, corresponding in body sounds' hypersensitivity relief. Clinically, AA may represent a first objective measure of body sounds' hypersensitivity in SCDS and, accordingly, be an accessible screening test for SCDS in not tertiary audiological centers.

- INTRODUCTION: A simultaneous recording of cervical and ocular vestibular evoked myogenic potential (sVEMP) to unilateral air-conducted (AC) stimulation reduces the test time and halves the sound load. MATERIALS AND METHODS: The sVEMP has been compared with the conventional sequential unilateral AC cervical and ocular VEMP in a consecutive cohort of 120 subjects attending the vestibular laboratory. The stimulus was a 500-Hz 6-ms tone burst, at 130 dB peSPL for sequential recordings but at 125 dB for the added sVEMP, for cumulative sound load containment. Amplitudes, latencies, and amplitude asymmetry ratios (ARs) were the parameters included in analysis. RESULTS: Relevant results were as follows: 1) significantly lower amplitudes in sVEMP versus VEMP (ocular recordings, median = 2.90 [IQR = 0-4.98] vs. 4.15 [1.73-8.98] μV, p < 0.001; cervical, 0.84 [0.30-1.69] vs. 1.36 [0.60-2.30], p < 0.001; electromyography scaled values); 2) 10% lower response rate at cervical recordings and 11% at ocular recordings in sVEMP, particularly in older subjects; 3) significant correlations between cervical amplitudes ( rs = 0.88, p < 0.001), ocular amplitudes ( rs = 0.71, p < 0.001), peak latencies ( rs = 0.36-0.67, p < 0.001), and ARs (ocular, rs = 0.56; cervical, rs = 68, p < 0.001); and 4) good agreement in pathological AR detection (cervical recordings, Cohen's κ = 0.649, p < 0.001; ocular, κ = 0.589, p < 0.001). DISCUSSION: AC sVEMP showed good correlation/agreement with sequential AC VEMP. Test time containment and halved sound load are clinical adds in sVEMP, opening to its use as laboratory standard. However, AC sVEMP presented reduced amplitudes and response rates, secondary to the reduced AC stimulation used in this study to allow checking of the null responses and the pathological ARs at AC sVEMP with conventional AC VEMP.

- This paper seeks to determine the decision-making route relating to hedonic and environmental motivation in green innovation adoption and to show how two similar green innovations can motivate consumers differently. It also aims to determine the effect of domain-specific innovativeness (DSI) on emotions and green identity on environmental motivations. The paper focuses on two types of green transport innovations: shared e-bikes and e-scooters. Four models were tested using structural equation modelling based on survey data from 800 shared e-bike and e-scooter users. The results reveal that the decision to use shared e-bikes follows a cognitive route, while shared e-scooter use follows an affective route. Additionally, findings show that DSI significantly affects positive emotions in the use of both shared microvehicles. However, green identity only impacts the environmental motivations in shared e-bike use.
