Background  In the past, consumers would go to physical stores to gather information and end their shopping there, with physical stores being one of the few sources of product information. Today, with the coming of the digital age, there are gradually more and more channels to gather information. The development of e-commerce, social media, and entertainment type of Internet has diversified the ways of consumption, thus triggering a change in retail channels. By integrating multiple channels and enhancing the consumer's sense of consumer experience, the retail industry is gradually moving toward omnichannel. Consumers tend to combine information from physical stores with information from multiple data sources to search, compare and buy, which gives rise to omnichannel shopping behaviour.  To provide consumers with a smoother shopping experience, omnichannel improves the functional limitations of cross-channel in multi-channel retail, allowing consumers to choose the channel and method they prefer and are accustomed to. This process breaks down the constraints of time and space and provides consumers with a more comfortable shopping experience. Therefore, this paper will focus on what affected consumers’ acceptance and use of omnichannel system.  Purpose  The purpose of this study is to consider omnichannel retail as a complete commercial system, and study what are key drivers for consumers to accept and use this system. Method  This thesis takes a qualitative research analysis by conducting 10 semi-structured interview of respondents who live in Sweden. 237 initial codes were used to analyse the data by using template analysis, and thematic coding was performed through categorization and structured layer-by-layer coding.  Conclusion  The determinants of customer behaviour in omnichannel retailing in the Swedish clothing industry are: perceived ease of use, perceived usefulness, perceived safety, perceived enjoyment, social influence, price value, and personal choice, and interaction was observed between these factors. These factors act synergistically on consumers' shopping intention and then influence consumer behaviour.

Regression analyses and delta-lognormal models were used to investigate whether river discharge and environmental variables significantly affected relative abundance of brown shrimp, Farfantepenaeus aztecus, in the northern Gulf of Mexico. Significant negative relationships were found between mean river flow during winter and spring months and catch rates (CPUE) off Texas, Louisiana and Mississippi/Alabama. However, during the same months significant positive relationships between CPUE and the variation in mean river discharge were found for each state. In Texas and Louisiana, delta-lognormal models revealed depth zone was the most significant variable (P≤0.001) in describing distribution, while time of day (P≤0.001) was most significant in describing CPUE and also distribution and CPUE in Mississippi/Alabama. These results suggest that brown shrimp relative abundance is effected by river discharge, while gulf-wide environmental variables exert no influence, except dissolved oxygen concentrations affecting distribution off Louisiana.

Os plantios do gênero Pinus nas regiões do Brasil são mais restritos em comparação ao Eucalyptus, principalmente pela adaptação climática de cada espécie. As espécies de pinus plantadas se destacam na região Sul e em parte da região Sudeste, enquanto nas outras regiões os plantios são pouco significativos. Assim, são necessárias pesquisas de novos materiais genéticos e inovações nas técnicas de cozimento para que o gênero Pinus se torne mais competitivo se consolide no mercado florestal. No presente estudo as árvores das espécies Pinus maximinoi e Pinus taeda (parâmetro de comparação) foram cortadas aos 7 anos de idade com o objetivo de avaliar as características anatômicas, físicas e químicas da madeira dessas espécies visando a produção de polpa celulósica kraft. Para a avaliação tecnológica dos materiais seguiram-se as principais análises: (1) Anatômica - os materiais foram descritos macro e microscopicamente e foram medidas as dimensões dos traqueídes e calculadas relações como coeficiente de flexibilidade, fração parede e índice de Runkel; (2) Física - foi determinada a densidade básica dos discos e cavacos, além da densidade aparente do lenho por densitometria de raios X; (3) Química - foram determinados o teor de extrativos, lignina, holocelulose e cinzas. Para as polpas obtidas pelo processo de polpação Lo-Solids® sendo determinado ao final de cada cozimento os rendimentos bruto, depurado e o teor de rejeitos. As condições de cozimento foram ajustadas visando a obtenção de polpa com número kappa 28±5%. Em relação às características anatômicas, a espécie P. maximinoi apresentou lenho tardio menos expressivo que P. taeda. As dimensões dos traqueídes tiveram diferenças significativas entre as duas espécies. Os valores médios para o comprimento, largura e diâmetro do lume dos traqueídes axiais foram superiores para a espécie P. taeda (3,8 mm, 62,6µm, e 54,8 µm, respectivamente) em relação à P. maximinoi (3,2 mm, 53,9 µm, e 44,0 µm). A densidade básica média ponderada foi de 0,361 g.cm-3 para P. maximinoi, não havendo diferença em comparação à espécie de P. taeda que apresentou densidade básica de 0,379 g.cm-3. A composição química das espécies não apresentou diferença estatística entre os resultados. P. maximinoi apresentou 3,98% de extrativos totais, enquanto P. taeda apresentou 4,51%, já o teor de lignina total foi de 31,81% e 32,16%, respectivamente. Sendo assim, as duas espécies apresentaram características tecnológicas muito semelhantes, o que propiciou um comportamento análogo frente ao processo de polpação Lo-Solids®, com algumas vantagens para espécie de P. maximinoi, que apresentou maior rendimento depurado (47,2%) - 1 ponto percentual a mais comparado à P. taeda (46,1%). E ainda por razões referentes às características silviculturais, o incremento médio anual em celulose (IMACEL) foi de 5,526 tsa.ha-1.ano-1 para P. maximinoi e de 4,101 tsa.ha-1.ano-1 para P. taeda. / Pinus plantations in the Brazilian regions are more restricted compared to Eucalyptus, mainly due to the climatic adaptation of each species. The planted pine species contrast in the South and part of the Southeast region of Brazil, while in other regions plantations are not significant. Therefore, research with new genetic materials and innovations in pulp processes are necessary to make pine species more competitive and consolidate in the forest sector. This study aimed to analyze the wood characteristics of 7-year-old Pinus maximinoi and Pinus taeda wood species for kraft pulp production. It were analyzed three wood characteristics: (i) Wood anatomy: macro and microscopical description and measurement of wood tracheids. (ii) Wood basic density (from wood discs and chips) and apparent density by X-ray densitometry technique; (iii) wood chemical characterization, including extractives, lignin, holocellulose and ash contents. Lo-Solids® pulping processes were carried out aiming pulps with kappa number of 28 ± 5%. The wood anatomy analysis showed that P. maximinoi presented latewood less distinct than P. taeda wood. The tracheids of P. taeda wood had greater length, width and lumen diameter (3.8 mm, 62.6 µm and 54.8 µm, respectively) than P. maximinoi tracheids. The basic density of P. maximinoi wood was 0.361 g.cm-3, slightly similar to P. taeda (0.379 g.cm-3). P. maximinoi and P. taeda chemical wood analysis resulted in 3.98% and 4.51% of total extractives content and 31.81 and 32.16% of total lignin content, respectively. The pulping processes resulted for P. maximinoi screened yield 1% higher than P. taeda pulp (47.2% and 46.1%). In addition, the forestry characteristics presents an advantage for P. maximinoi species, which resulted in 5.526 tsa.ha-1 year-1 of average annual increase in cellulose (IMACEL) compared to 4.101 tsa.ha-1 year-1 for P. taeda species.
