Detaljhandeln är en marknad som är under ständig utveckling och möts av nya utmaningar. Den hårda konkurrensen driver de verksamma till att arbeta med butiken och dess miljö som en konkurrensfördel. Det satsas och investeras årligen i stora ombyggnationer av butiker där detaljister planerar, bygger, förändrar och kontrollerar organisationens fysiska miljö utan att i många fall fullt förstå hur det påverkar ”användare” av miljön. Baserat på vad som skapar värde för konsumenter vid köptillfället kommer de ställa olika krav på butiksmiljön och således påverka hur de upplever det totala shoppingvärdet. Det blir därför viktigt att definiera konsumentens värdedimension för att också förstå butiksmiljöns betydelse och påverkan.Den hedonistiska värdedimensionen som syftar till emotionella värden så som underhållande och trevlig shopping har fått större utrymme inom detaljhandeln. Detaljisternas ökade strävan av en hedonistisk butiksmiljö som fokuserar på inspiration och upplevelse i butik har medfört att det utilitaristiska värdet fått mindre utrymme, en inriktning mer fokuserad på en behovsstyrd och funktionell konsumtion. Lite forskning har gjorts kring den utilitaristiska värdedimensionen samtidigt som många människor lever utifrån en alltmer hektisk livsstil vilket tycks innebära ett ökat behov av bekvämlighet och effektivitet i de sammanhang där de kan erhålla eftersökta varor.Studiens syfte är att undersöka och analysera betydelsen av butiksmiljön och dess faktorer för konsumenter vid utilitaristisk konsumtion. Studien ämnar också besvara hur detaljister genom butiksmiljön kan skapa värde för konsumenter vid utilitaristisk konsumtion. Då det krävs ens djupare förståelse för den utilitaristiska värdedimensionen och hur den påverkar konsumenternas uppfattning om vad som skapar värde för dem i butiksmiljö har studiens empir samlats in genom fokusgrupper. För att skapa förståelse för mönster och beteenden samt för att förebygga en spretig datainsamling har fokus riktats mot en typ av produkt. Då underkläder betraktas som en utilitaristisk produkt och som oftast exponeras i en hedonistisk miljö föreföll det vara en lämplig och intressant produkt att använda som undersökningsfall. Då underklädesavdelningen för kvinnor har större variation av produkter och modeller än den manliga avdelning, samtidigt som de oftast har större utrymme i butik styrdes urvalet mot underkläder för kvinnor. Fyra fokusgrupper genomfördes med kvinnor i åldrarna 23-59 år.Studiens resultat visar att butiksmiljön blev mindre viktig för konsumenter vid utilitaristisk konsumtion. Konsumenter lägger större fokus på att uppnå sitt köpmål och hitta efterfrågad produkt än upplevelsen i butik. Butikens förmåga att tillhandahålla och erbjuda rätt utbud av produkter var av störst betydelse för konsumenter vid utilitaristisk konsumtion. Det var också av stor betydelse att faktorerna i butiksmiljön underlättar och effektiviserar köpprocessen genom en tydlig layout och varuvisning, tillgänglig personal samt genom en lugn och behaglig miljö. Vid utilitaristisk konsumtion kan detaljister således skapa värde för konsumenter genom att främst erbjuda rätt produkter men också genom att skapa en tydlig layout, struktur, ha tillräcklig bemanning samt sträva efter en butiksmiljö som satsar på funktion framför inspiration. / The retail industry is a market experiencing constant change and new challenges. Tough competition pushes companies to work on their store environment in order to attain competitive advantage. Retailers annually make significant investments to plan, build, change, and control the organizations’ physical environment, and in many cases, without understanding how it truly affects the actual “users” of the environment. Based on the consumers’ preferences and value at the time of purchase they will generally have different requirements of the store environment and how they experience and evaluate it. As a result, it becomes important to define the consumers value dimension in order to understand the importance and effect that the physical environment has on the consumer.Whereas the hedonic store environment has gained more recognition, where inspiration and experience is in focus, few studies have been done on the utilitarian value which focuses on the needs-driven and functional consumption. At the same time people tend to have an increasingly busy lifestyle where an increased need of convenience and efficiency where they make their purchase is sought after. This study aims to increase understanding of the importance of the store environment and its factors in utilitarian consumption. The study intends to examine how retailers, through their store environment, can create value for consumers with a utilitarian value dimension.To be able to answer the research questions it requires a deeper understanding of the utilitarian value dimension and how it affects consumers’ view of what creates value for them in the store environment; the study is therefore conducted through focus groups. To understand consumers’ patterns and behaviors and to prevent a too wide data collection the study focuses on only one product. As underwear is considered a utilitarian product that people use on an everyday basis and mostly is exposed in a hedonistic environment; it appeared to be an appropriate and interesting product to use. In general, the women’s lingerie department will show a wider assortment of products than the respective department for men; as a result, the sample of the study was tilted towards underwear for women. Four focus groups were conducted with women in an age range of 23-59.The result of the study revealed that the store environment became less important to consumers with a utilitarian value dimension. Consumers put more focus in achieving their goal of a purchase and finding the requested product than what they experience in store. A store’s ability to provide and offer the right range of products was of the greatest importance for consumers when it comes to utilitarian consumption. It was also of great importance that the store environment provided possibilities for the consumers to make the purchase process efficient by providing a clear layout, simple exposure of the products, service and creating a calm and comfortable environment. In utilitarian consumption retailers can create value for consumers by offering the right products, creating a clear layout and structure, have sufficient staffing and aim for store environments that focus on function rather than inspiration.This thesis is hereinafter written in Swedish.

This dissertation investigated the effects of spatialized auditory cues on the development of situation awareness for teams. Based on extant research, it was hypothesized that 3-D spatialized auditory cues can be utilized by teams to develop knowledge about team member location in addition to supporting the usage of team behaviors for developing and maintaining situation awareness. Accordingly, the study examined how situation awareness would be differentially influenced by varying the type of auditory cues incorporated into virtual environment (VE) team training scenarios within the context of a MOUT team task. In general, the results of this study provided partial support for the beneficial effects of 3-D audio cues in facilitating the development of situation awareness and reducing workload. Implications are discussed in the context of design guidance for VE training systems.

While humans can separate a sound of interest amidst a cacophony of contending sounds in an echoic environment, machine-based methods lag behind in solving this task. This thesis thus aims at improving performance of audio separation algorithms when they are informed i.e. have access to source location information. These locations are assumed to be known a priori in this work, for example by video processing. Initially, a multi-microphone array based method combined with binary time-frequency masking is proposed. A robust least squares frequency invariant data independent beamformer designed with the location information is utilized to estimate the sources. To further enhance the estimated sources, binary time-frequency masking based post-processing is used but cepstral domain smoothing is required to mitigate musical noise. To tackle the under-determined case and further improve separation performance at higher reverberation times, a two-microphone based method which is inspired by human auditory processing and generates soft time-frequency masks is described. In this approach interaural level difference, interaural phase difference and mixing vectors are probabilistically modeled in the time-frequency domain and the model parameters are learned through the expectation-maximization (EM) algorithm. A direction vector is estimated for each source, using the location information, which is used as the mean parameter of the mixing vector model. Soft time-frequency masks are used to reconstruct the sources. A spatial covariance model is then integrated into the probabilistic model framework that encodes the spatial characteristics of the enclosure and further improves the separation performance in challenging scenarios i.e. when sources are in close proximity and when the level of reverberation is high. Finally, new dereverberation based pre-processing is proposed based on the cascade of three dereverberation stages where each enhances the twomicrophone reverberant mixture. The dereverberation stages are based on amplitude spectral subtraction, where the late reverberation is estimated and suppressed. The combination of such dereverberation based pre-processing and use of soft mask separation yields the best separation performance. All methods are evaluated with real and synthetic mixtures formed for example from speech signals from the TIMIT database and measured room impulse responses.

This study examined gender and self-monitoring as separate and interacting variables predicting judgmental accuracy on the part of observers of facial expressions of emotional categories. The main and interaction effects failed to reach significant levels during the preliminary analysis. However, post hoc analyses demonstrated a significant encoder sex variable. Female encoders of emotion were judged more accurately by both sexes. Additionally, when the stimulus was limited to female enactments of emotional categories, the hypothesized main and interaction effects reached significant F levels. This study utilized 100 observers and 10 encoders of seven emotional categories. Methodological considerations and alternatives are examined at length.

The chemosensory abilities of fishes, are important in order to understand how prey can perceive and avoid predators. Predator-naïve Channel catfish were exposed to four extracts over eight sessions (naïve bass water (NBW), bass that were fed catfish water (BFCW), catfish skin extract (CS), and naïve bass water paired with catfish skin extract (CO)) to determine whether they have an innate predator response to potential chemical cues indicating possible predation risk. Movement was quantified as grid squares crossed, directional changes, and tail beats. Response increased during the first minute following stimulus injection and decreased during the second minute. Channel catfish increased movement upon exposure to stimuli from NBW, CS and CO but not to BFCW. Increased response to bass odor while habituating to catfish skin extract, which presumably contains alarm pheromone, suggests that catfish learned to recognize bass odor without external reinforcement.

Arthropod predators often use prey and conspecific cues to make foraging decisions. Calosoma wilcoxi (Leconte) is a voracious predatory beetle that specializes on lepidopteran larvae often found in the forest canopy, including the fall cankerworm. This study tested the hypothesis that C. wilcoxi uses olfactory cues to detect prey and conspecifics. A Y-tube olfactometer was used to test attractiveness to larvae, larval frass, conspecific cues, and volatiles from herbivore-damaged white oak leaves. C. wilcoxi did not preferentially choose the treatment in any of the experiments. There was no difference in mean time spent in the treatment or control arm for any of the cues assayed. The time to choose the treatment was significantly shorter in the female conspecific experiment only. I found no evidence that C. wilcoxi uses olfaction to locate prey; however, C. wilcoxi is attracted to conspecifics. C. wilcoxi may use conspecific cues to make informed foraging decisions.

Fornecer dicas durante o período de manutenção de estímulos em tarefas de memória de trabalho melhora o desempenho dos participantes tanto para a acurácia quanto para o tempo de resposta (TR). Esse fenômeno é chamado de efeito de dicas retroativas. Nós realizamos três experimentos usando uma tarefa de reconhecimento de itens para testar a suposição de que o efeito das dicas retroativas é dependente de uma representação imagética disponível à inspeção consciente no momento da apresentação da dica. No Experimento 1, nós manipulamos o tamanho do conjunto (2 e 3 itens) a ser memorizado e inserimos uma tarefa de busca visual no intervalo de retenção para evitar a recitação visual dos estímulos. Nós aplicamos o método dos fatores aditivos de Sternberg para medir o tempo gasto pelos participantes para reativar os itens memorizados na forma de imagens mentais. O intercepto da função linear entre TR e tamanho do conjunto sofreu um incremento de 400 ms na presença da busca visual. No Experimento 2, nós inserimos 500 ms de tela em branco após a tarefa de busca visual e imediatamente antes do aparecimento da dica, para que os participantes usassem esse intervalo para reativar os itens na forma de imagens mentais. O efeito da dica retroativa ocorreu tanto para o TR quanto para o índice de discriminação (d). No Experimento 3, nós manipulamos a natureza da tarefa concorrente durante o intervalo de retenção: busca visual, monitoramento de tons e discriminação de cores. A busca visual foi a mais prejudicial ao desempenho dos participantes e ao efeito da dica retroativa, seguida pela discriminação de cores. A combinação de demanda atencional e necessidade de processamento visual presente na busca visual é especialmente prejudicial ao desempenho. Concluímos que o funcionamento das dicas retroativas é modulado por esses dois fatores, e não só por recursos atencionais centrais. Os resultados apoiam um modelo de memória de trabalho que considera o fenômeno da imaginação mental em sua arquitetura / Providing cues during the maintenance period of working memory tasks improves participants\' performance in terms of accuracy and response times (RT). This phenomenon is known as the retro-cue effect. We performed three experiments to test the assumption that the retro-cue effect relies on an imagetic representation of the stimuli, available to conscious inspection at the moment of the cue\'s onset. In Experiment 1, we manipulated the number of stimuli (set size 2 and 3) and inserted a visual search task during the retention interval to prevent visual rehearsal. We applied the Sternberg\'s additive factors method to measure the time participants spent to reactivate the items under the form of mental images. The intercept of the linear function between RT and set size increased 400 ms in the presence of the visual search. In Experiment 2, we added 500 ms of blank screen after the visual search task and immediately before the cue\'s onset, so that participants could use this interval to reactivate the items as mental images. The retro-cue effect occurred both for the RT and the discrimination index (d\'). In Experiment 3, we manipulated the type of the concurrent task during the retention interval: visual search, tone monitoring, and color discrimination. The visual search was the most deleterious task for the participants\' performance and for the retro-cue effect, followed by the color discrimination. The combination of attentional demand and visual processing in the visual search was particularly deleterious to performance. We concluded that the functioning of retro-cues is modulated by those two factors, and not only by central attentional resources. The results support a working memory model that considers the phenomenon of mental imagery in its architecture

In this experiment it was investigated how scent affect the memory. Encoding information in the same context as retrieving it has been suggested to be beneficial for memory, earlier research has mostly explored how environmental contextual cues affects the memory. In this research the contextual cue was created by a presentation of a scent. The participants were presented with two lists of words, during the encoding of the first list all the participants were presented with a scent, half of the group was directed to forget the first list straight after encoding and the other half to keep remembering the list. For the second list no one was presented with a scent. In the retrieval of both lists half of each group was reinstated with the scent they were presented with at encoding and the other half without the scent (control group). The data were analysed with univariate ANOVAs and significant effects were followed up with independent-samples t-test. The results were that participants that were reinstated with the scent were thought to remember more than the others, however there was only a significant difference in the forget condition with reinstatement, where they remembered less than in the other conditions.

The main objective of this thesis is to investigate acoustic cues for the voicing contrast in stops in Russian for effects of speaking rate and phonetic environment. Although the laryngeal contrast in Russian is assumed to be a [voice] contrast, very few experimental studies have looked at the acoustic properties of Russian voiced and voiceless stops. Most claims about acoustic properties of stops and phonological processes that affect them (voice assimilation and final devoicing) have been made based on impressionistic transcriptions. The present study provides evidence that (1) voicing in voiced stops is affected by speaking rate manipulation, (2) stops in Russian retain underlying voicing contrast in presonorant position and voice assimilation occurs only in obstruent clusters, and (3) phonological processes of voice assimilation and final devoicing do not result in complete neutralization. The target of the investigation is voiced and voiceless intervocalic stops, stops in clusters, and final stops in different prosodic positions within a word and at the phrase level. The acoustic cues to voicing (duration of voicing, stop closure duration, vowel duration, f0, and F1) were measured from the production data of 14 monolingual speakers of Russian recorded in Russia. Speakers produced words and phrases with target stops in three speaking rate conditions: list reading, slow rate and fast rate. The data were analyzed in 5 blocks focusing on (1) word-internal stops, (2) voice assimilation in stops in prepositions, (3) cases of so-called "sonorant transparency", (4) voice assimilation in stops before /v/, and (5) voicing processes across a word boundary. The results of the study present a challenge to the widely-held assumption that phonological processes precede phonetic processes at the phonology-phonetics interface. It is shown that the underlying contrast leaves traces on assimilated and devoiced stops. To account for the findings, a phonology-phonetics interface that allows interaction between the modules is required. In addition, the results show that temporal cues are affected by speaking rate manipulation, but the effect of rate on voicing is found only in voiced stops. Duration of voicing and VOT in voiceless stops are not affected by speaking rate. The results also show that no effect of C2 is obtained on voicing in C1 stops in in obstruent-sonorant-obstruent clusters, thus no "phonological sonorant transparency to voice assimilation" is found in Russian. Rather, the study provides evidence that there is variation in production of voicing in stops in prepositions, and that voice assimilation in stops before /v/ followed by a voiced obstruent is optional for some speakers.
