A study on investigating the impact of website features on online impulse buying behaviour

E-commerce has led to many deliveries in business relationships specially used for online shopping. Given the growth of e-commerce to increase e-shopping, researchers can be investigated in this area in recent years. This paper aims to investigate the effect of website features on online impulse buying behaviour (OIBB). A questionnaire survey was conducted on the users of the Digi Kala website. They have made an impulsive online purchase at least once from the DigiKala website in Arak city, Iran. A relative stratified sampling technique was utilized for data collection. The data were analyzed statistically. The results show that: All research hypotheses have been confirmed. Among the research variables for the research's statistical sample, service quality and visual attraction affect online impulsive shopping behaviour.

The Effects of Ozone on Visual Attraction Traits of Erodium paularense (Geraniaceae) Flowers: Modelled Perception by Insect Pollinators

Ozone (O3) effects on the visual attraction traits (color, perception and area) of petals are described for Erodium paularense, an endangered plant species. Plants were exposed to three O3 treatments: charcoal-filtered air (CFA), ambient (NFA) and ambient + 40 nL L−1 O3 (FU+) in open-top chambers. Changes in color were measured by spectral reflectance, from which the anthocyanin reflectance index (ARI) was calculated. Petal spectral reflectance was mapped onto color spaces of bees, flies and butterflies for studying color changes as perceived by different pollinator guilds. Ozone-induced increases in petal reflectance and a rise in ARI under NFA were observed. Ambient O3 levels also induced a partial change in the color perception of flies, with the number of petals seen as blue increasing to 53% compared to only 24% in CFA. Butterflies also showed the ability to partially perceive petal color changes, differentiating some CFA petals from NFA and FU+ petals through changes in the excitation of the UV photoreceptor. Importantly, O3 reduced petal area by 19.8 and 25% in NFA and FU+ relative to CFA, respectively. In sensitive species O3 may affect visual attraction traits important for pollination, and spectral reflectance is proposed as a novel method for studying O3 effects on flower color.

Defining Color Change in Pitaya: A Close Look at Betacyanin Synthesis Genes in Stenocereus queretaroensis

Betalains are tyrosine-derived plant pigments present in several species of the Caryophyllales order. Betalains are classified in red betacyanins and yellow betaxanthins and are implicated in plant stress tolerance and visual attraction for pollinators. The compounds are used as natural colorants in many industries. Today, there is little information on betalain biosynthesis with several key enzymes that remain unknown on plants of the Caryophyllales order. Omic tools have proven to be very useful in gaining insights into various molecular mechanisms. In this study, we used suspension cells from fruits of the cactus Stenocereus queretaroensis. Two growing conditions were used to perform RNA-seq and differential expression analysis to help identify betalain biosynthesis-related genes. We found 98 differential expressed genes related to aromatic amino acids and betalain biosynthesis pathways. Interestingly, we found that only one gene of the betalain synthesis pathway was differentially expressed. The rest of the genes belong to the aromatic amino acid pathway, including hydroxy phenylpyruvate-related genes, suggesting the possibility of an alternative biosynthetic pathway similar to that observed in legumes.

Visibility and attractiveness of Fritillaria (Liliaceae) flowers to potential pollinators

Visual floral characters play an important role in shaping plant-pollinator interactions. The genus Fritillaria L. (Liliaceae), comprising approximately 140 species, is described as displaying a remarkable variety of flower colours and sizes. Despite this variation in visual floral traits of fritillaries, little is known about the potential role of these features in shaping plant-pollinator interactions. Here, we seek to clarify the role of visual attraction in species offering a robust food reward for pollinators early in the spring, which is the case for Fritillaria. We also searched for potential tendencies in the evolution of floral traits crucial for plant-pollinator communication. The generality of species with green and purple flowers may indicate an influence of environmental factors other than pollinators. The flowers of the studied species seem to be visible but not very visually attractive to potential pollinators. The food rewards are hidden within the nodding perianth, and both traits are conserved among fritillaries. Additionally, visual floral traits are not good predictors of nectar properties. When in the flowers, pollinators are navigated by nectar guides in the form of contrasting nectary area colouration. Flower colour does not serve as a phenotypic filter against illegitimate pollinators—red and orange bird-pollinated fritillaries are visible to bees.

Continuance Intention of Augmented Reality Textbooks in Basic Design Course

The Basic Design course can help students understand design principles and visual art elements It is a compulsory basic course for the department of art and design in many universities. In recent years, Augmented Reality (AR) technology has found its way into the field of design education and has become a popular textbook tool in teaching courses. There are not many pieces of research on the application of AR in design courses. Therefore, this study attempts to explore the factors that affect students’ acceptance of AR textbooks in Basic Design course and their continuance intention for AR textbooks. This study first focused on students with experience in using AR textbooks. Open-ended questions were used to collect factors that allow AR textbooks to be used in the design curriculum; then questionnaire surveys and factor analysis were conducted and the research hypotheses are presented. Then, the research hypotheses were verified through reliability and validity as well as structural equation modeling. Three factors and 15 items for students to accept AR textbooks in the Basic Design course were summarized in the research results, including the three factors named “Visual Attraction”, “Knowledge-ability”, and “Situational Experience”. The analysis of differences showed significant differences in gender among these three factors and no significant differences between grades and departments. Also, it was found from the analysis results of the structural equation model that the factors of “Visual Attraction” and “Knowledge-ability” both had a positive effect on the continuance intention, of which “Knowledge-ability” was the most important influencing factor. The results of this study can help the application and development of AR textbooks in the Basic Design course.

Light environment influences mating behaviours during the early stages of divergence in tropical butterflies

Speciation is facilitated when traits under divergent selection also act as mating cues. Fluctuations in sensory conditions can alter signal perception independently of adaptation to the broader sensory environment, but how this fine-scale variation may constrain or promote behavioural isolation has received little attention. The warning patterns of Heliconius butterflies are under selection for aposematism and act as mating cues. Using computer vision, we extracted behavioural data from 1481 h of video footage, for 387 individuals. We show that the putative hybrid species H. heurippa and its close relative H. timareta linaresi differ in their response to divergent warning patterns, but that these differences are strengthened with increased local illuminance. Trials with live individuals reveal low-level assortative mating that is sufficiently explained by differences in visual attraction. Finally, results from hybrid butterflies are consistent with linkage between a major warning pattern gene and the corresponding behaviour, though the differences in behaviour we observe are unlikely to cause rapid reproductive isolation as predicted under a model of hybrid trait speciation. Overall, our results reveal that the contribution of ecological mating cues to reproductive isolation may depend on the immediate sensory conditions during which they are displayed to conspecifics.

Innate visual attraction in wood ants is a hardwired behaviour seen across different motivational and ecological contexts

ABSTRACTWood ant foragers show an innate attraction to conspicuous visual cues. These foragers inhabit cluttered woodland habitat and feed on honeydew from aphids on trees, hence, the attraction to ‘tree-like’ objects might be an ecologically relevant behaviour that is tailored to wood ant foraging ecology. Foragers from other ant species with different foraging ecologies show innate attractions different to wood ants. What we do not know, however, is whether these innate visual responses vary with the ants’ motivational states or caste. We thus recorded the innate visual response of wood ant foragers with different motivational states, i.e. unfed or fed, as well as males that have a short life span and show no foraging activity. Our results show that ants from all three groups orient towards the visual cue, i.e. the wood ants’ innate visual attraction is not context dependent, but a hardwired behaviour seen across different motivational and ecological contexts.

ANTHOCYANINS PROFILES OF SOME AUTOCHTONOUS GRAPEVINE CULTIVARS FOR RED WINES, CULTIVATED AT DRĂGĂȘANI, ROMÂNIA

The Dragasani vineyard is one of the most ancient existing in Romania being famous for obtaining red and white wines of the highest quality. The present study has performed during five years (2005-2009), focusing on the anthocyanin profiles of the autochthonous Novac grapevine cultivar, in comparison with Cabernet Sauvignon cultivar which, also provides wines of high quality. The obtained results put into evidence, a special potential and chromatic structure in case of the grapes and wines characteristics for these autochthonous cultivars, which are very closed to those shown by the Cabernet Sauvignon. For all the cultivars studied, the amounts of cationical flavidium within the anthocyanin matter do keep continuously was growing, while acidity decreased and glucides was accumulated. However, at some moment, these synthesis indices of the cromatical structure’s quality begin to decline. Depending of the viticultural year it is the genetical nature of the respective anthocyanin pigments to differentiate through the involvements of each of the 3 categories of pigments (yellow, red or blue). During the wine’s evolution (maturation and aging), due to the modification of its cromatical structure, the ratio between the yellow and red pigments does confer to the wine a colour nuance which continues to increase, significantly improving the wine’s visual attraction. For the autochthonous grapevine cultivars for red wines, their antocyanins potential their respective qualities do enable us to state that on the basis of the quality of the raw materials, wine types of high qualities could be created, being so endowed that they could bear as well an origin denomination.
