Apple or Huawei: Understanding Flow, Brand Image, Brand Identity, Brand Personality and Purchase Intention of Smartphone

The global use of smartphone has had tremendous social, environmental, and economic impacts in the last decade, and continues to grow impressively. In order to comprehend customers’ purchase behavior, it is crucial to understand the driving force behind their choice of one specific brand among various competitors. A few prior researches have demonstrated that not only the optimal experience of flow, but also identity features (i.e., self-identity, social identity, brand identity) facilitate a customer’s purchase intention. Previous studies also indicate that brand-related constructs (e.g., typically brand image but sometimes also brand personality and communication) predict purchase intention. As the first study combining flow, which focuses on investigating the consumer purchase behavior through identity and brand-related constructs, we propose a conceptual model that combines flow theory, brand image, brand communication, brand identity, and brand personality to investigate purchase intention. We have empirically tested the conceptual model based on the data collected from 1377 Chinese smartphone users. Results via the structural equation modeling with AMOS software indicated that flow experience, brand image, brand communication, brand personality, and brand identity all directly or indirectly explain purchase intention. Flow experience serves a critical role in mediating the path from brand communication, brand personality, and brand identity to purchase intention. The research focuses on the strategic implication of the various brand features management and aims to harmonize economic, social, and environmental sustainability.
The clonal and population structure of a rare endemic plant, Wyethia reticulata (Asteraceae): allozyme and RAPD analysis

Genetic structure arises when limited gene flow between populations favours the development of distinct arrays of genetic characters within each population. Determining the spatial scale at which this differentiation occurs is critical to our understanding of population biology and microevolution of species. The genetic structure and spatial pattern of genetic variation in an endemic, clonal perennial, Wyethia reticulata E. Greene, was investigated using random amplified polymorphic DNA (RAPD) markers and allozyme alleles. Large stands (250–360 m2) were found to contain few genetic individuals. Despite the small population sizes and endemism of the species, W. reticulata was highly diverse genetically, with most of the variation (75–81%) distributed within populations. A population structure in full agreement with spatially defined populations was achieved only by combining RAPD and allozyme markers. Analysis using both types of markers appeared to provide estimates of genetic similarity between individuals that were most consistent with empirical data on plant distributions. We postulated that large, long‐lived clones dominated genetic relationships within populations but also provided opportunities for gene flow between populations on a longer time scale. The two marker types yielded different estimates of between‐individual similarity and revealed disparate patterns of population structure. This result will arise because allozymes and random DNA segments have dissimilar evolutionary dynamics with respect to mutation and selection.
Characterization of a FLORICAULA/LEAFY Homologue of Gnetum parvifolium and Its Implications for the Evolution of Reproductive Organs in Seed Plants

The morphological variation among reproductive organs of extant seed plants makes assessment of organ homology difficult. Comparisons of expression patterns of homeotic genes that control organ development will yield new information about the homology of organs to assess inferences deduced from previous morphological studies. In angiosperms, the FLORICAULA/LEAFY (FLO/LFY) genes convert a vegetative shoot meristem to a floral meristem by inducing floral homeotic genes, most of which belong to the MADS‐box gene family. To provide insights into the evolution of reproductive organs in seed plants, a FLO/LFY homologue (GpLFY) was cloned from Gnetum parvifolium. GpLFY mRNA was expressed in both the vegetative shoot apex and the female strobilus. The GpLFY mRNA signal was detected in early developmental stages of the collar and the ovule primordium, including the nucellus and three envelopes. A comparison of FLO/LFY gene expression in Gnetum and the conifer Pinus radiata indicates that the Gnetum collar and ovule are homologous with the conifer bract and ovule‐ovuliferous scale complex, respectively. Overexpression of GpLFY in transgenic Arabidopsis promoted a conversion of a shoot meristem to a floral primordium. The Arabidopsis LFY null mutant, lfy‐26, with a malformed flower, was complemented by overexpression of GpLFY. These results indicate that the inductive pathway from the FLO/LFY gene to the MADS‐box genes already existed in the common ancestor of angiosperms and gymnosperms.
Ramifications of elevated temperature on the growth and yield performances of rice varieties incorporated with indigenous organic amendments

A field experiment was conducted at Chandipur of Keraniganj Upazilla in the district of Dhaka, Bangladesh to screen out the studied rice varieties of BR 3, BRRI dhan 28, Local BRRI dhan 29, and BRRI dhan 74 as influenced by the Rice Straw Compost – RSC, Mustard Meal – MM, and Trichocompost – TC (indigenous organic amendments), and elevated soil temperature of 3°C in relation to the growth and yield response of rice. The experiment was conducted using split plot design with elevated temperature in main plots and the different rates of organic amendments in subplots. The rates of organic amendments were 0. 4, 8 t ha-1 for RSC; 0, 3, 6 t ha-1 for MM; and 0, 2.5, 5 t ha-1 for TC. The soil temperature was raised by 3°C from the daily field temperature of 22-25°C. Grain and straw yields, 1000-grain weight, number of filled and fissured grains of rice were significantly (p≤0.05) enhanced with the increased rates of RSC, MM, and TC at elevated temperature of 3°C.The maximum grain (8.86 t ha-1) and straw (8.40 t ha-1) yields were recorded in the treatment RSC4HW26-28 and RSC8HW26-28, respectively in BRRI dhan 29 over control, which endorsed the lowest grain (3.42 t ha-1) and straw (2.68 t ha-1) yields. The RSC treatment was ranked first in order of the growth-yield and yield components (1000 – grain weight and No. of filled and fissured grain) of rice followed by MM and TC treatments. The aforesaid treatments were found to have significantly (p≤0.05) positive aftermath with the elevated soil temperature, regardless of rice varieties. Increased rice production by the elevated soil temperature might be due to the CO2 fertilization, which is a very important climatic issue at present day environment.
Soccer games and record-breaking PM2.5 pollution events in Santiago, Chile

Abstract. In wintertime, high concentrations of atmospheric fine particulate matter (PM2.5) are commonly observed in the metropolitan area of Santiago, Chile. Hourly peaks can be very strong, up to 10 times above average levels, but have barely been studied so far. Based on atmospheric composition measurements and chemistry-transport modeling (WRF-CHIMERE), the chemical signature of sporadic skyrocketing wintertime PM2.5 peaks is analyzed. This signature and the timing of such extreme events trace their origin back to massive barbecue cooking by Santiago's inhabitants during international soccer games. The peaks end up evacuated outside Santiago after a few hours but trigger emergency plans for the next day. Decontamination plans in Santiago focus on decreasing emissions from traffic, industry, and residential heating. Thanks to the air quality network of Santiago, this study shows that cultural habits such as barbecue cooking also need to be taken into account. For short-term forecast and emergency management, cultural events such as soccer games seem a good proxy to prognose possible PM2.5 peak events. Not only can this result have an informative value for the Chilean authorities but also a similar methodology could be reproduced for other cases throughout the world in order to estimate the burden on air quality of cultural habits.
A Wearable EEG Instrument for Real-Time Frontal Asymmetry Monitoring in Worker Stress Analysis

A highly wearable single-channel instrument, conceived with off-the-shelf components and dry electrodes, is proposed for detecting human stress in real time by electroencephalography (EEG). The instrument exploits EEG robustness to movement artifacts with respect to other biosignals for stress assessment. The single-channel differential measurement aims at analyzing the frontal asymmetry, a well-claimed EEG feature for stress assessment. The instrument was characterized metrologically on human subjects. As triple metrological references, standardized stress tests, observational questionnaires given by psychologists, and performance measurements were exploited. Four standard machine learning classifiers (SVM, k-NN, random forest, and ANN), trained on 50% of the data set, reached more than 90% accuracy in classifying each 2-s epoch of EEG acquired from the stressed subjects.
Morphophysiological Traits as Indicators of Genetic Diversity in Brazilian Populations of Jatropha curcas L. Grown Under Water Deficit

Jatropha curcas L. (Euphorbiaceae) is a species grown in tropicalcountries and used for biodiesel production. Morphophysiological traits were analyzed to assess the genetic diversity in nine genotypes of J. curcas under deficit water. Seeds of plants from different populations, collected in diferente brazilian regions, were grown under two water regimes (100% and 50% tank capacity). Multivariate analysis was used to characterize genetic diversity. The UPGMA dendrogram built from the genetic distance group indicated the segregation of genotypes into five groups for growth traits and six groups for physiological traits. Then, an principal components analysis was carried out, to evaluate the pattern of character variations and then segregate the characteristics that could distinguish parental genotypes for use in plant breeding. Results showed 65.50% and 56.02% for the two first principal components of growth and physiological traits, respectively. Total root area was the most determining trait for genetic dissimilarity (18.9%) and group formation, followed by plant height (17.9%) and number of leaves (17.6%). On the other hand, stomatal conductance (gs) (24.9%) and guaiacol peroxidase (GPX) (20.9%) were the most determining physiological traits. The analysis of morphophysiological traits indicated CNPAE-298 and 299 as the most distant genotypes among the plant groups. Under water-limited conditions, total root area, plant height, gs and GPX were the most efficient traits to explain genetic dissimilarity among the genotypes, and for this reason they should be referred as a priority for further studies on genotypes selection in this species.
Ultrastructural Changes in Cotyledons of Pineapple Guava (Myrtaceae) During Somatic Embryogenesis

Abstract Ultrastructural studies (SEM and TEM) were performed on cotyledons of pineapple guava (Feijoa sellowianaBerg, Myrtaceae) induced to form embryos on medium containing 1.0 mg l−1(4.5μ M 2,4-D) and 0.3 M sucrose. At the time of culture, the cells were filled with protein and lipid bodies. Microbodies and poorly differentiated organelles could also be seen. In contrast to germinating cotyledons, where lipid and protein reserves were quickly metabolized, cells of the embryogenically induced cotyledons showed evidence of reserve consumption only after 5 d of culture. Subepidermal cells of the upper cotyledonary surface underwent several divisions giving rise to a meristematic layer of several cells thickness from which somatic embryos developed. Embryos could also be formed directly by successive divisions of epidermal cells. Cells involved in somatic embryo formation contained a large nucleus with a conspicuous nucleolus and dense cytoplasm where numerous ribosomes, mitochondria, plastids with starch and short profiles of rough endoplasmic reticulum were present. Plasmodesmata were present both in cell walls of the meristematic cells and in few celled embryos whereas in degenerating embryos or in more advanced stages of somatic embryo development no plasmodesmata could be found. Although oil bodies were not observed in the meristematic cells they were identified in very young embryos, being the first reserve compounds to appear. Cells not involved in somatic embryo differentiation were characterized by the presence of several microbodies containing a crystalloid inclusion and elongated mitochondria.
Current role of Pipelle endometrial sampling in early diagnosis of endometrial cancer

Endometrial cancer is the most common gynecologic cancer in developed countries. The most prevalent, however not pathognomonic symptom of the disease is abnormal uterine bleeding. The diagnosis of endometrial cancer is based on the histologic results of endometrial sampling. Endometrial biopsy could be obtained using different modalities: hysteroscopy-directed endometrial biopsy, uterine curettage or office endometrial biopsy. Outpatient endometrial biopsy using different devices for the evaluation of abnormal uterine bleeding is gaining popularity. The most popular office-based device for endometrial sampling procedure is the Pipelle device. Currently, Pipelle endometrial sampling is widely used to diagnose endometrial cancer in women with abnormal uterine bleeding and/or postmenopausal bleeding. The method became very useful due to easiness and simplicity of the procedure, availability of a device, as well as high sensitivity in detecting endometrial cancer. Many studies compared the validity and accuracy of Pipelle biopsy with dilation and curettage in the detection of various endometrial pathologies. Published results state that Pipelle biopsy and uterine curettage are almost equally reliable in the evaluation of endometrial pathologies. Moreover, Pipelle biopsy appears more beneficial as it does not require hospital admission and anaesthesia. However, it is proven the Pipelle technique has a limited capacity to identify endometrial polyps, and some authors, based on their study, claim that dilation and curettage is a more reliable method in terms of correlation with the final histological results. In addition, there are many factors affecting the efficiency of the endometrial biopsy. Failure to get samples that are adequate for histological examination is one of the problems associated with Pipelle sampling. The above mentioned contradictory conclusions by different researchers and lack of guidance to avoid inadequate sampling present the demand for further studies on the comparison of Pipelle biopsy and uterine curettage efficiency and accuracy.
The production of antimicrobial compounds by British marine algae II. Seasonal variation in production of antibiotics

Eleven known antibiotic-producing species of British marine algae were quantitatively screened at monthly intervals for the presence of antibacterial compounds. The antibacterial components of the algae were extracted with acetone and then assayed against Staphylococcus aureus. The results indicate that seasonal variation in antibiotic production occurs in some marine algae and also that four main patterns of production can be discerned. These are, (a) the Polysiphonia type, in which antibiotic production occurs iniformly throughout the year; (b) the Laminaria type, which is characterised by maximum antibiotic production occurring during the winter months, this is also found in Chondrus crispus, Laurencia pinnatifida and Ulva lactuca; (c) the Dictyota type, possessing a summer peak of activity, which also occurs in Dilsea carnosa and Ascophyllum nodosum; (d) the Codium type, where there is a spring peak of activity, this is also exhibited by Halidrys siliquosa.
Rhythmic variability, language, and style: A replication and extension of nPVI findings with the RISM dataset

The normalised pairwise variability index (nPVI), has been frequently used to measure the rhythmic variance between musical onsets. For example, researchers have proposed connections between the nationalities of composers and the nPVI values of their music and native language. One particular issue, however, lies in the notion of intended nationality – composers frequently wrote in national styles other than their own. This study employs the RISM-World dataset to both replicate previous findings relating the rhythmic variance of melodies to the nationalities of composers, and to examine intended nationality in the music of Mozart and Handel, namely their operas and oratorios.
The impact of the provision of water for game on the basal cover of the herbaceous vegetation around a dam in the Kruger National Park

A line intercept survey was done on the herbaceous vegetation in permanently marked plots at distance intervals from the Wik-en-Weeg Dam, Kruger National Park, in 1973. The survey was repeated in 1990 so that changes in basal cover could be determined in relation to distance from the dam. Positive relationships with distance from the dam were found for the relative total percentage basal cover of the herbaceous vegetation, as well as for the relative basal cover of, respectively, grasses, forbs, decreasers and increasers. It was concluded that the provision of a permanent supply of drinking water for game in the Wik-en-Weeg Dam has had an impact on the nearby herbaceous community basal cover composition, as well as a negative impact on the basal cover of the herbaceous vegetation in the vicinity. The basal cover of the herbaceous stratum was more sensitive to the effect of the dam than parameters of the woody stratum.
Second-Log Branch Size Comparison Between Even-aged and Multiaged Douglas-fir Stands in Coastal Northern California

We studied how forest management decisions affect branching of coastal Douglas-fir Pseudotsuga menziesii var. menziesii in coastal northern California because knot sizes can affect performance, grade, and value of structural lumber. We focused on branching in the second log which is located immediately above the butt log and constitutes an important part of a tree's wood volume and potential value. Branch diameters were measured on multiple Douglas-fir trees nested within 40 plots sampling even-aged and multiaged stands. We analyzed two tree-level branch size metrics that can be influential in log grading: (i) the basal diameter of the largest branch on the log, and (ii) the average diameter of the largest branch on each quadrant (termed BIX). Generalized linear mixed-effects regression analysis revealed that branches were smaller in multiaged stands than even-aged stands. Trees with larger branches also had larger DBH and crown width, and lower height:diameter ratio. Branch diameters were more sensitive to competition from their nearest neighboring trees than overall stand density or basal area of larger trees. Since neighboring trees exerted control over branch development, and if large branches are undesirable, managers may consider implementing more dispersed patterns of retention and limiting creation of edges.
Lack of directed Vα14‐Jα281 rearrangements in NK1+ T cells

NK1.1+ T cells are an unusual subset of TCRαβ cells distinguished by their highly restricted Vβ repertoire and predominant usage of an invariant Vα14‐Jα281 chain. To assess whether a directed rearrangement mechanism could be responsible for this invariant α chain, we have analyzed Vα14 rearrangements by polymerase chain reaction and Southern blot in a panel of cloned T‐T hybrids derived from thymic NK1.1+ T cells. As expected a high proportion (17/20) of the hybrids had rearranged Vα14 to Jα281. However, Vα14‐Jα281 rearrangements always occurred on only one chromosome and were accompanied by other Vα‐Ja rearrangements (not involving Vα14) on the homologous chromosome. These data argue that rigorous ligand selection rather than directed rearrangement is responsible for the high frequency of Vα14‐Jα281 rearrangements in NK1.1+ T cells.
Neutron-Induced Radiation Damage in LYSO, BaF2, and PWO Crystals

One crucial issue for the application of scintillation crystals in future high-energy physics experiments is radiation damage in a severe radiation environment, such as the high luminosity large hadron collider. While radiation damage induced by ionization dose in inorganic scintillators is well understood, investigations are ongoing to understand radiation damage induced by hadrons, including both charged hadrons and neutrons. Aiming at understanding neutron-induced radiation damage in fast inorganic scintillators, lutetium yttrium oxyorthosilicate (LYSO)/lutetium fine silicate (LFS), BaF<sub>2</sub>, and PWO crystals were irradiated at Los Alamos Neutron Science Center by a combination of particles, including neutrons, protons, and <inline-formula> <tex-math notation="LaTeX">$\gamma $ </tex-math></inline-formula>-rays. The results indicate that LYSO/LFS and BaF<sub>2</sub> crystal plates are radiation hard up to a 1-MeV equivalent neutrons fluence of <inline-formula> <tex-math notation="LaTeX">$9 \times 10^{15}$ </tex-math></inline-formula> equivalent neutron (n<sub>eq</sub>)/cm<sup>2</sup>, but not PWO, and the neutron-induced radiation damage in LYSO crystals is a factor of ten less than protons.
Efficient haploid induction in wheat by using pollen of Imperata cylindrica.

Intergeneric hybridization between wheat (Triticum aestivum L.) and a wild weedy species, Imperata cylindrica (2n = 20) resulted in the recovery of a high frequency of wheat haploids, which were obtained through the elimination of I. cylindrica chromosomes. Cytological analysis of the root tips revealed the somatic chromosome count of the regenerants equalled 21. Haploid regenerants were also obtained in all the crosses of wheat F 1 s with I. cylindrica, implying the genotype nonspecific nature of wheat x I. cylindrica hybridization. Variation among wheat F 1 hybrids was observed with respect to seed formation (44.9-84.5%), embryo formation (15.1-47.7%) and regeneration (27.0-75.0%) in crosses with I. cylindrica. Comparisons based on the efficiency of I. cylindrica and maize (Zea mays) as pollen sources indicated that Imperata-mediated haploid production is equally efficient. There is natural coincidence of flowering period of I. cylindrica with that of wheat under sub-temperate conditions which is advantageous compared with maize, which cannot be grown during the winter season in the sub-temperate regions.
