A REVIEW ON TECHNOLOGY READINESS CONCEPT TO EXPLAIN CONSUMER’S ONLINE PURCHASE INTENTION

Recently in Malaysia, a substantial number of consumers have been found to be avoiding online shopping as they prefer to shop in physical stores. This scenario brings up the issue of whether Malaysian consumers are ready technologically to shop online. To tackle this issue, a review of the concept of technology readiness is made to help explain Malaysian consumers’ online purchase intention behaviour. Technology readiness is chosen here because the concept reflects an individual’s predisposition in the usage and adoption of new technology. For the purpose of this review, this study selects technology readiness concept as proposed by Parasuraman (2000). From the review, this study found that technology readiness has been measured in the past either as a single (unidimensional) or a multidimensional construct involving four factors, namely, optimism, innovativeness, discomfort and insecurity. A summary on past researchers’ findings in identifying the relationship between technology readiness (and its proposed dimensions) with technology usage is included in this review. For example, technology readiness was found to have a significant influence on behavioural intention in using mobile commerce to purchase travel-related service. Additionally, technology readiness motivator (optimism and innovativeness) and inhibitor (discomfort and insecurity) were identified to be related to intention to use technology. Based on the review, this study proposes a model to help explain the user’s intention to purchase online situation. In the proposed model, both technology readiness motivators and inhibitors are suggested to show positive and negative influences respectively on the user’s intention to purchase online. This review is thought to be beneficial to many. For instance, researchers would find insights on the usefulness of technology readiness and on how it has been and can be applied for further investigation. As for marketing practitioners, the review would help guide them understand the influence technology readiness has on consumers behaviour intention in adopting online shopping which they could apply for future marketing strategy.
UV Disinfection of Adenovirus: Present State of the Research and Future Directions

Adenoviruses are nonenveloped, double-stranded DNA viruses that infect humans, causing dysentery and respiratory infection. Adenovirus has become a focus of the water treatment community because of its apparent resistance to ultraviolet (UV) disinfection and is the basis for stringent new regulations from the U.S. Environmental Protection Agency regarding UV disinfection of all viruses. Most of the work done so far, however, has involved the use of monochromatic (254 nm) low-pressure UV sources and assay of viral inactivation in cell culture models. Adenovirus is most likely not truly resistant to UV damage but is instead damaged and then repaired in host cells during cell culture infectivity assays. Recent research has shown that newer, polychromatic UV sources are more effective than monochromatic low-pressure UV at inactivating adenovirus. The potential for viral DNA repair in cell culture necessitates the use of alternative assay methods to measure UV disinfection efficiency: these include molecular biology and animal infectivity assays. Research to help clarify the effects of UV on adenovirus should therefore address two major issues not addressed in most studies published so far: the nature of (a) the UV source used to inactivate the virus and (b) the assays used to determine inactivation and characterize viral response. In this review, the authors discuss previous work on UV inactivation of adenovirus as well as present and ongoing work designed to address these two issues.
Structure relationship to dielectric, elastic and chiral properties

Crystallography provides a major approach toward reaching an understanding of the relationship between crystal structure and material physical properties. The specific relationships of five highly structure dependent physical properties, namely piezoelectricity, pyroelectricity, ferroelectricity, ferroelasticity and optical activity, to atomic arrangement are developed in this Lead Article. The major attributes of each property, together with the structural measurements required to establish the property–structure relationship, are introduced and illustrative results for each are given. Predictive criteria that emphasize the insight leading to new property-structure relationships are presented as is an expanded experimental access to the crystallographic study of materials.
Synthesis and Characterization of Colored Polyureas

ABSTRACT Various disperse dyes based on m-phenylenediamine have been prepared. These dyes were then polycondensed with Toluene 2, 4-diisocyanate. The resultant colored polyureas were characterized by elements analyses, IR spectral studies, estimation by monaqueous conductometric titration and thermogravimetry. All the polyureas were subjected to electrical conductivity determination at room temperature.
Bioconcentration and bioavailability of organotin compounds : Influence of pH and humic substances

Bioconcentration of triphenyltin (TPT) and tributyltin (TBT) was studied in the freshwater organisms Daphnia magna (zooplankton), Chironomus riparius (sediment organism) and Thymallus thymallus (fish yolk-sac larvae). TPT bioconcentration factors (BCFs) at pH 8 were highest for Thymallus (2200), followed by Chironomus (680) and Daphnia (190). The differences could not be fully explained by different total lipid contents. Metabolism and lower bioconcentration were observed for TBT in Chironomus. The BCFs of both TBT and TPT were higher at pH 8 than at pH 5, but the difference was much less pronounced than predicted by the octanol-water partition model. This suggests that, besides the hydroxide species (TBTOH and TPTOH), the cations (TBT and TPT + ) are also taken up by the organisms to some extent and that the octanol-water partition model underestimates the uptake of the charged species. Low concentrations of humic substances (HS) led to small reduction in the bioconcentration of TPT in Daphnia and Thymallus, and a significant reduction occurred at relatively high concentrations of HS (>10 mg C 1 -1 ). The results of this study provide an important basis for future investigations aiming at a better understanding of the bioavailability and fate of TBT and TPT in freshwater ecosystems.
Effect of water stress on the growth of Arachis pintoi plants under different nitrogen levels

The objective was to evaluate the growth of Arachis pintoi fertilized with nitrogen and water deficiency conditions. The study was developed in a 4 × 4 factorial arrangement with four nitrogen levels (0, 40, 80 and 120 kg N/ha) and four irrigation levels (25, 50, 75 and 100% of field capacity), in a completely randomized experimental design, with four replications. High doses of N benefited the production of root shoots while the root increased its production at a dose of 40 kg N/ha. The number of green and senescent leaves were influenced by N fertilization and the water regime, where higher doses of N provided greater total number of green leaves (364 leaves/pot) and the limitation of water resulted in a greater number of senescent leaves (78 leaves/pot). Observing the maximum point, the water regime of 90% of field capacity and 120 kg N/ha favored leaf appearance rate of 1.2 leaves/day and less phyllochron (4.6 days/leaf) at 85% of field capacity and 115 kg N/ha. The dose of 120 kg N/ha resulted in ultimate greater width (1.4 cm) and length (2.4 cm) of the leaf at 100% of field capacity. The final length of stolons showed quadratic effect for N, having greatest length (58.1 cm) at 75 kg N/ha and 100% of field capacity.
Prognostic Factors for Borderline Resectable / Locally Advanced Pancreatic Ductal Adenocarcinoma Undergoing Resection

Background: Advancement of neoadjuvant treatment (NT) has alternated the management of borderline resectable pancreatic ductal adenocarcinoma (BR-PDAC), potentially changed the determinant of prognosis. Methods: Clinicopathological data of patients with BR-PDAC who underwent resection between 01/2008 and 12/2018 at a single institution were retrospectively reviewed. Univariable and multivariate analyses were used to compare survival between patients who received NT vs. those who underwent upfront resection (UR). Results: A total of 138 patients with BR-PDAC were included in the study, 64 underwent UR and 74 NT. NT resulted in higher R0 resection rate (68.9%) compared with UR (43.8%, p=0.005). NT was associated with improved overall survival (OS, p=0.009) and progression-free survival (PFS, p=0.027). R0 resection was also associated with improved OS (p<0.001) and PFS (p<0.001). On multivariable analysis, when adjusting for clinically relevant variables without considering R status, NT was an independent
Measurements and modelling of ozone in the Mediterranean MBL: an investigation of the importance of ship emissions to local ozone production

Abstract. Elevated concentrations of ground level ozone are both hazardous to human health and detrimental to agricultural production. The Mediterranean Basin, due to its position under the descending branch of the Hadley Cell circulation during the summer months, enjoys periods of stable, sunny and warm weather which provide ideal conditions for the production of ozone. The presence of major population centres and numerous industrialised areas in the coastal zone result in both a continual supply of ozone precursor compounds and also a significant number of people to suffer the consequences of high ozone concentrations. Using the WRF/Chem model validated with data obtained from seven oceanographic measurement campaigns, performed between 2000 and 2010, aboard the Italian Research Council's R. V. Urania, and also from a number of EMEP monitoring stations located around the Mediterranean Basin, the importance of emissions from maritime traffic in the region has been investigated. The model results indicate that over large areas of the Mediterranean emissions from shipping contribute between 5 and 10 ppb to the ground level O3 daily average concentration during the summer. The contribution to the hourly average O3 is up to 40 ppb in some particularly busy shipping lanes. Importantly the results suggest that in a number of coastal areas the contribution from ship emissions to the local O3 concentration can make the difference between complying with the EU Air Quality standard of a maximum 8 h mean of 120 μg m−3 and exceeding it.
Studies on the effect of different micro-nutrients on quality attributing parameters of banana (Musa paradisiaca L.) cv. Grand Naine

A field experiment on the “Effect of different micro-nutrients on growth parameters of banana (Musa paradisiaca L.) cv. Grand Naine” was carried out at instructional farm Pt. Kishori Lal Shukla College of Horticulture and Research Station (IGKV) Rajnandgaon, Chhattisgarh during the year 2015-16 employing randomized block design having eleven treatments replicates thrice. The treatment consisted eleven different combination of micronutrients along with recommended dose of fertilizers viz. RDF + FeSO4 (0.5%), RDF +ZnSO4(0.5%), RDF + CuSO4 (0.2%), RDF +Borax (0.1%), RDF + ZnSO4 (0.5%) + FeSO4 (0.5 %), RDF + ZnSO4 (0.5%) + CuSO4 (0.2 %), RDF + ZnSO4 (0.5%) + Borax (0.1%), RDF + FeSO4 (0.5 %) + CuSO4 (0.2 %), RDF + FeSO4 (0.5 %) + Borax (0.1%), RDF + ZnSO4 (0.5%) + FeSO4 (0.5 %) + CuSO4 (0.2 %) + Borax (0.1%) and water spray (control). The experiment was conducted on banana crop cv. Grand Naine with foliar application of micro-nutrients singly and in combinations along with fertigation of recommend dose of fertilizers applied at 3rd, 5th and 7th month after planting. The quality parameters of fruit in terms of total soluble solids, reducing, non-reducing, total sugar and ascorbic acid content was proved to be best showing a higher status with the treatment F5. The maximum total soluble solids (23.85%), reducing sugar (11.92%), non-reducing sugar (6.48 %), total sugar (18.40) and ascorbic acid (12.98 mg/100 g) was recorded under the treatment F5 (RDF + ZnSO4 (0.5%) + FeSO4 (0.5 %)), however the minimum was recorded under the treatment RDF+Control. The acidity of fruit decreased by the application of RDF + ZnSO4 (0.5%) + FeSO4 (0.5 %). The maximum weight of pulp (147.12g) was observed under the superiority of treatment RDF + ZnSO4 (0.5%) + FeSO4 (0.5% however, the minimum (95.84 g) was recorded under the treatment (RDF + control) (F0). The minimum weight of peel (34.59 g) was observed under the treatment F5 (RDF + ZnSO4 (0.5%) + FeSO4 (0.5%) and the maximum weight of peel (42.59 g) was noticed under the treatment F0 (RDF + control). Application of (RDF + ZnSO4 (0.5%) + FeSO4 (0.5 %)) showed significant difference and recorded maximum pulp: peel ratio (4.21), while minimum pulp: peel ratio (2.25) was noticed under the treatment F0 (RDF + Control).
Effect of bromine chemistry on the atmospheric mercury cycle

[1] Bromine chemistry is believed to play a major role in the atmospheric oxidation of elemental mercury (Hg0) to divalent mercury (HgII). However, its effect on the speciation of atmospheric mercury (Hg) has been mostly ignored in models of the fate and transport of mercury. We investigate the effect of bromine chemistry on Hg speciation for various reaction kinetics and environmental conditions with a box model. Bromine chemistry was also added to the chemical mechanism of a global chemical transport model, and simulations of the global mercury cycle were conducted with different sets of bromine reaction kinetics. The global model simulations conducted with bromine chemistry lead to Hg0 concentrations that are consistent with observations only if the pressure dependence of the kinetics of the oxidation of Hg0 by Br is taken into account. Bromine chemistry is found to reduce the overall lifetime of Hg by about 10%.
Elastic constants, debye temperatures, and electron-phonon parameters of superconducting cuprates and related oxides

Abstract Using both measurements and modeling, we studied the cohesive and related properties of several oxides. Superconducting oxides include La1.85Sr0. 15CuO4, Y1Ba2Cu3O7, and (Bi-Pb)2Sr2Ca2Cu3O10. Related nonsuperconducting oxides include SrTiO3, BaTiO3, and La2CuO4. For these materials, we give the complete quasiisotropic elastic constants corrected to the void-free state. From elastic constants and atomic volume, we calculated Debye characteristic temperatures, Θ D . Using Kresin's model, valid for all values of the electron-phonon parameter, λ, we estimated I from Tc and Θ D . For the superconducting cuprates, λ ranges from 1.3 (La-O) to 10.0 (Tl-O). Except perhaps for Tl-O, these parameters fall within a range predicted by theory. For all the above materials, we show the 295–5-K variation of Θ D . We support our elastic-constant measurements with Born-model calculations of the bulk modulus.
Specimen surface preparation errors in quantitative electron-probe microanalysis

The usual method of specimen preparation for electron-probe microanalysis can introduce errors of up to about ±3% in the estimates of the amount of an element present. It is believed that these errors are caused by the formation of `flowed' layers on the surfaces of polished samples. Two methods of reducing the errors are described.
SWISS VIDEO GAME HISTORY AND THE SMAKY ERA: BOOTSTRAPPING A PLATFORM ARCHAEOLOGY STUDY

Introduction In this paper, we propose a set of guidelines which can serve to conduct projects combining preservation and analytical tasks concerning a given platform, including its video games, especially at a regional level. As the capabilities of such local platforms influenced how video games were to be designed and developed, we consider that they must be documented and understood when studying regional video games history during eras when local platforms were more frequent. We illustrate our approach with an ongoing research project focused on the heritage of the Swiss computer Smaky (1978–1995) and the video games it welcomed.
Examining the Virtual Diffusion of Educational Resources across Teachers’ Social Networks over Time

Context Individuals’ curation within social media provides a window into their sensemaking and conceptions of what is worth knowing. Within education, a majority of teachers use social media for professional purposes to access and share instructional resources. Purpose This work examines Pinterest.com and the intersection of influence across virtual and physical spheres as teachers choose and curate instructional resources. Setting: The study is conducted on 19 schools over five districts in three Midwestern states. Participants The sample consists of 108 elementary teachers in total: 34 early career teachers and 74 colleagues. Research Design This is a longitudinal observational study designed to repeatedly measure and track teachers’ online resource-seeking behavior over 52 weeks in the 2015–2016 school year. Data Collection and Analysis Resource curation data were collected for each teacher, as well as early career teachers’ egocentric school network and online network data. Using generalized linear growth modeling approach to examine relationships between teachers’ curation of resources, we identify differences in the impacts of teachers’ social networks across physical and virtual space. Findings Results indicate that teachers following one another within Pinterest have a higher rate of curating a resource, but Pinterest seems to act as a bridge between those less connected teachers within a school, with an even greater rate of curation for those teachers who do not closely work together. This seems to indicate that within the cloud of social media, Pinterest may be a conduit for information and resource distribution across schools. Conclusion As schools continue to seek improvement potential, leveraging social media connections and social capital within and outside the local context may prove useful for the flow of expertise and resources.
Housing Market and Entrepreneurship: Micro Evidence from China

Using a unique survey data of Chinese households, we study the impact of house price growth and house price risk on entrepreneurship. House price risk, measured as the sensitivity of house price growth to local GDP growth, negatively impacts the entrepreneurship of homeowners relative to renters. This finding is concentrated only among sophisticated households and is consistent with the portfolio effect when housing and occupational choices are integral parts of the household portfolio. Moreover, a high past house price growth reduces the entrepreneurship of homeowners relative to renters. This holds for both sophisticated and unsophisticated households. We propose a new economic channel based on extrapolative belief and provide further supportive evidence.
Leaching of heavy metals and nutrients from calcareous sandy‐loam soil receiving municipal solid sewage sludge

Leaching column experiments were conducted to determine the degree of mobility of heavy metals (HMs) and nutrients after the addition of municipal solid sewage sludge (MSS) in a sandy-loam soil. Treatments were (1) soil application of low metal content MSS, (2) soil application of metal-enriched municipal solid sewage sludge (EMSS), and (3) control. The MSS application represented a dose of 200 Mg dry weight (dw) ha–1. Soil columns were incubated at room temperature for 15 d and were irrigated daily with distilled water to make a total of 557 mm. Leachates were collected and analyzed for HMs and nutrients. The Ni and Pb added to soil via MSS and EMSS were found to be leached through the 20 cm columns of calcareous sandy soil although Ni and Pb concentrations in the percolate were small relative to the total amounts of metals applied. Losses of K+ from the EMSS, MSS, and control were 92.5, 82.0, and 52.5 kg ha–1, respectively. Losses of Mg2+ were in the range from 104.4 (control treatment) to 295.2 kg ha–1 (EMSS), while the loss of Ca2+ was in the range from 265.0 (control treatment) to 568.2 kg ha–1 (EMSS). The results showed that the amounts of P leached from EMSS (3.02 kg ha–1) and MSS (2.97 kg–1 ha–1) were significantly larger than those from the control treatment (1.54 kg ha–1). The geochemical code Visual MINTEQ was used to calculate saturation indices. Leaching of P in different treatments was controlled by rate-limited dissolution of hydroxyapatite, β-tri-Ca phosphate, and octa-Ca phosphate. The results indicate that application of MSS to a sandy soil, at the loading rate used in this study, may pose a risk in terms of groundwater contamination with Ni, Pb, and the studied nutrients.
Volume-outcome relationship in health, inequalities in access to care and referral of patients for specialized care

Cette these de doctorat etudie la question de la centralisation des soins pour le traitement du cancer, et apporte des preuves empiriques sur de nombreux aspects lies a cette problematique. Le chapitre 1 explore la relation entre le volume d’activite des hopitaux et la qualite des soins pour le traitement du cancer de l’ovaire. L’exploitation d’une base de donnees comprenant des informations tres detaillees sur le degre de severite du cancer nous a permis de mettre en evidence de tres fortes disparites de survie en fonction du volume d’activite de l’etablissement de prise en charge. Le deuxieme chapitre de cette these vise a identifier les mecanismes soutenant cette relation, et plus particulierement la contribution du choix du traitement par les cliniciens dans l’effet causal du volume d’activite sur la qualite des soins. Les resultats confirment la contribution du processus de selection du traitement par les cliniciens dans l’effet causal du volume d’activite sur la qualite des soins, et apportent ainsi de nouveaux elements permettant caracteriser l’effet d’apprentissage induit par le volume d’activite. Le chapitre 3 a pour objectif d’evaluer l'impact d'une centralisation des soins pour le traitement du cancer du sein et de l’ovaire sur les inegalites spatiales et socioeconomiques d'acces aux soins specialises. En exploitant une base de donnees administrative nationale, nos resultats indiquent une forte deterioration de l’acces aux soins specialises si une telle reforme etait appliquee, ainsi qu’une repartition territoriale et socioeconomique tres inegale du fardeau de la centralisation. Dans une perspective plus large, il est primordial de mieux comprendre les mecanismes lies a l’adressage des patients vers les hopitaux, afin de mieux saisir la necessite - ou non - de centraliser les soins. L’objectif du quatrieme chapitre de cette these est d’identifier les preferences des patients dans le choix de leur etablissement de prise en charge pour le traitement du cancer, en tenant compte du role du medecin traitant dans l’adressage. Nos resultats soulignent le role central du medecin traitant dans le processus de d’adressage, et mettent en evidence des facteurs limitant le libre choix de l’etablissement de prise en charge.
