Attention training (AT) is a therapeutic intervention developed by Adrian Wells that involves the training of attentional skills to treat emotional disorders (Wells, 1990). This study investigated whether the AT technique works as theorised to reduce anxiety and other symptoms by reducing self-focus. In a laboratory setting, seventy-one student participants were exposed to a single session of either an AT analogue or a control treatment to see if AT would reduce their self-focus and vulnerability to a subsequent stressor task. AT was not found to decrease self-focus or reduce vulnerability to the stressor. In addition, self-esteem (SE) and social anxiety were investigated as potential moderators of the relationship between AT and/or self-focus on vulnerability to the stressor. Prior research has shown that SE level and self-focus interact such that self-focus predicts vulnerability to anxiety in people with low SE, but not in those with high SE. In this study we also examined SE range, a measure we developed here to reflect the range within which a person’s state SE fluctuates over time. The results indicated that self-focus is related to increased vulnerability in those with low SE or a large SE range, but decreased vulnerability in those with high SE or a small SE range. This supports theorising that self-focus activates people’s self-beliefs, which then influence how they respond during potentially threatening experiences. The findings also support the recommendation that SE range be subjected to further evaluation.

A computational technique is introduced to reveal the complex intrinsic structure of homoclinic and heteroclinic bifurcations in a chaotic dynamical system. This technique is applied to several Lorenz-like systems with a saddle at the center, including the Lorenz system, the Shimizu-Morioka model, the homoclinic garden model, and the laser model. A multi-fractal, self-similar organization of heteroclinic and homoclinic bifurcations of saddle singularities is explored on a bi-parametric plane of those dynamical systems. Also a great detail is explored in the Shimizu-Morioka model as an example. The technique is also applied to a re exion symmetric dynamical system with a saddle-focus at the center (Chua's circuits). The layout of the homoclinic bifurcations near the primary one in such a system is studied theoretically, and a scalability ratio is proved. Another part of the dissertation explores the intrinsic mechanisms of escape in a reciprocally inhibitory FitzHugh-Nagumo type threecell network, using the phase-lag technique. The escape network can produce phase-locked states such as pace-makers, traveling-waves, and peristaltic patterns with recurrently phaselag varying.

Den omfattande globaliseringen som sker i världen har givit upphov till stora förändringar för världens organisationer. Den ständigt växande konkurrensen som kommer därav ökar kraven på en fungerande internkommunikation samt betydelsen av att de interna kommunikationskanalerna utnyttjas så effektivt som möjligt. Samtidigt krävs långtgående hänsynstaganden gällande alla organisationens medlemmar då utveckling av internkommunikationens struktur och strategi genomförs.   I detta examensarbete används teorierna “Uses and gratifications”, “Dependency theory” och ”Social information processing theory”. Teorierna används med målsättning att beskriva de mest framträdande dragen i den interna kommunikationsutövningen i en organisation och vidare för att undersöka hur denna utövning överensstämmer med de förväntningar och användningsmönster som kan utrönas bland de anställda. Med utgångspunkt i tidigare forskning inom ämnet framkommer vikten av att utföra studien från ett användarperspektiv i en organisation som bedriver industriell produktion såväl som kontorsarbete. Skillnader mellan dessa olika grupper i fråga om upplevelser och förväntningar inkluderades också i undersökningen.           Studien genomfördes på ett teknologiföretag i södra Sverige i ett skede där lansering av en ny intranät-portal väntade. Det empiriska materialet erhölls genom utförande av sju fokusgruppsintervjuer. Totalt deltog 28 personer i dessa fokusgrupper. Resultatet visade på många tillgängliga interna kommunikationskanaler samtidigt som det synliggjorde en upplevd avsaknad av en tydlig strategi och en utsedd koordinator som ansvarar för den interna kommunikationen.  Från ett medarbetarperspektiv karaktäriseras den generella internkommunikationen av inkonsekvens, otillförlitlighet och godtycklighet. Olika typer av strategier för att tillfredsställa specifika behov kunde identifieras såväl som långtgående beroenden av vissa informationskanaler för att få information. Kollaborationsplattformar som en integrerad del av intranätet mötte motsägelsefulla åsikter och visar på att de anställda både önskar och fruktar det fria ordet i organisationskommunikativa sammanhang. De interna kommunikationskanalsera måste struktureras och samköras för att ge alla organisationsmedlemmar möjlighet att tillfredställa sina informations- och kommunikationsbehov.

This paper presents the results of a focus group study exploring older individuals' perceptions of older drivers. The study extends the stereotype research of Joanisse, Gagnon, and Voloaca (2012b), further investigating the terms used to describe older drivers. Also explored were the ways older adults perceive age versus health in their considerations of driving. Three focus groups (N=24) were conducted with former and current drivers, 64 years and older, living in Asheville, North Carolina. Participants showed positivity in their descriptions of older drivers as "slow" and "cautious" and believed they adapted their driving behavior as aging demanded. Participants showed heterogeneity in their acceptance of the health issues that threatened their continued driving ability. The importance of context in understanding stereotypes of older adults is illustrated. Results are discussed in terms of ingroup/outgroup theory in line with the proposed model.

Mobile banking is an application of mobile computing which provides customers with the support needed to be able to bank anywhere, anytime using a mobile handheld device and a mobile service such as text messaging (SMS). Mobile banking removes space and time limitations from banking activities such as checking account balances, or transferring money from one account to another. In recent research and studies it was found that while mobile banking and more specifically SMS-based mobile banking applications have become popular in some countries and regions, they were still not widely used. This study identifies and investigates the factors which influence customers’ decision to use a specific form of mobile banking, and specifically focuses on the evaluation of SMS-based mobile banking in the context of New Zealand. The research model includes the basic concepts of the Technology Acceptance Model (TAM), as well as some constructs derived through a focus group discussion. The model is tested to determine its predictive power with respect to individual’s behaviour when considering the use of SMS-based mobile banking. A survey questionnaire was developed and employed to collect data from 250 AUT university students in New Zealand. The results of the data analysis contributes to the body of knowledge in the area by demonstrating that context specific factors such as service quality and service awareness are influencing user perceptions about the usefulness of SMS mobile banking which in turn affect intention to use and adoption. Secondly, the study demonstrates, on the example of SMS-based mobile banking, how a hybrid approach involving qualitative data collection and a subsequent quantitative survey can help investigate how user perceptions about usefulness and ease of use are formed. Although the study has its limitations, the implications of the results allow providing practical recommendations to the banking industry, and directions for further work.
