EFFECT OF ONLINE PAYMENT SECURITY ON THE BUYING BEHAVIOUR OF THE ONLINE SHOPPERS IN CHENNAI CITY

Online shopping is flattering more accepted due to its ease and affordability. But that doesn‟t mean online shopping is with no flaw or drawbacks. Payment security is big question mark in the online shopping; consumers are facing such issues every day. To safeguard the interests of the online shopping consumers there are security systems and payment systems available to protect against deception and security related threats, but still there is a threat of security breaches for online stores. This present study examines the features of online payment security threats with reference to online shopping consumers‟ purchase intentions. This research further approached the online shopping customers in Chennai city as representatives and all those representatives were contacted by mail along with the questionnaires. The data was collected from 305 respondents and the Structural equation modeling (SEM) with Wrap-PLS is administered to examine the data. The findings of the research shows that a fit model to enlighten online shopping consumers‟ purchase intentions. The outcomes of the study expose a good mediating effect relationship of perceived usefulness on online payment security and purchase intentions of the customers. Further, the perceived ease of use also has an important indirect effect, all the way through digital payment security, on the purchase intentions of the online shopping customers. Moreover accepting the ease and adoption of the security sides of the payment affect the purchase intentions of the online shopping consumers. The outcomes of the research also give more awareness over various security aspects in electronic transactions.
Gene-Environment Interactions Between Environmental Response Genes Polymorphisms and Mitochondrial DNA Copy Numbers Among Benzene Workers

Supplemental Digital Content is available in the text Objective: To determine the effect of mitochondrial DNA copy number (mtDNAcn) as a biomarker of benzene exposure. Methods: A total of 294 benzene-exposed workers and 102 controls were recruited. Biomarkers of mtDNAcn, cytokinesis-block micronucleus (MN) frequency, and peripheral blood white blood cells (WBC) were detected. Eighteen polymorphism sites in DNA damage repair and metabolic genes were analyzed. Results: Benzene exposure increased mtDNAcn and indicated a dose–response relationship (P < 0.001). mtDNAcn was negatively correlated with WBC count and DNA methylation and positively correlated with MN frequency. The AG type in rs1695 interacted with benzene exposure to aggravate mtDNAcn (β = 0.006, 95% CI: 0, 0.012, P = 0.050). rs13181, rs1695, rs1800975, and GSTM1 null were associated with benzene-induced mtDNAcn. Rs1695 interacted with benzene to increase mitochondrial damage. Conclusions: Benzene exposure increases mtDNAcn levels in benzene-exposed workers.
Exercise stress assessed by automated measurements of salivary testosterone and cortisol levels and testosterone/cortisol ratio within circadian rhythms in male long-distance runners

Background: Exercise stress promoted cortisol and testosterone secretions that have their own circadian rhythms. It is necessary that the testosterone, cortisol and testosterone/cortisol ratio (T/C ratio) are measured through their rhythms for use in monitoring exercise-induced stress in athletes. Automated measurement has not been applied to salivary testosterone, which requires passive drooling difficult to collect sufficient saliva rapidly. This study aimed to verify whether automated measurements of the testosterone and cortisol concentrations and T/C ratio using saliva collected sequentially can effectively assess exercise intensity differences within circadian rhythms in male athletes.Methods: We investigated the correlations of testosterone and cortisol concentrations measured by electrochemiluminescence immunoassay (ECLIA) between saliva and sera collected from 20 male long-distance runners. We collected the runners' saliva sequentially by passive drooling on two consecutive days involving different intensity trainings in the morning and evening; salivary testosterone and cortisol concentrations were measured by ECLIA. Each exercise intensity was measured by running distances, velocities, Borg scale score and maximum pulse rate during exercise.Results: The salivary testosterone and cortisol concentrations were positively correlated with the respective total serum hormone concentrations. The runners were divided into low-intensity exercise group (n = 8) and high-intensity exercise group (n = 7), in which five runners were excluded because measurable saliva samples could not be obtained due to low volume and high-viscosity. Sequential saliva collection and automated measurements detected the runners' circadian rhythms of testosterone, cortisol and T/C ratio. The rate of change in the salivary cortisol concentrations were significantly higher and that in the T/C ratio was significantly lower in the evening interval training on day 1 in the high-intensity exercise group which had significantly higher running velocity, Borg scale score, and maximum pulse rate values; this relationship was not shown for salivary testosterone.Conclusions: Automated measurements of the salivary cortisol concentration and the T/C ratio reflected different exercise intensities may be useful for creating appropriate exercise programs for athletes. Conversely, the automated measurements of salivary testosterone and T/C ratio, which require passive drooling to collect saliva, may be less suitable for practical use with athletes than the salivary cortisol-only measurement
Synthesis and characterization of the copper nanoparticles

Copper hydrosol were prepared from the solution of copper nitrate with NaBH4 by reductive reaction in water and ethanol-water system in the presence of NaOH and CTAB,and the copper hydrosol were transferred into organic phase by the addition of PAMDTCD.FTIR,TEM,XPS and XRD were utilized to investigate the structure and stability of copper nanoparticles modified with PAMDTCD.The results showed that the modified copper nanoparticles are stable in ambient conditions,which is attributed to the protection of the PAMDTCD molecular densely packed on the copper surface.
Training preferences of homelessness assistance service providers: a brief report

ABSTRACT This brief report presents results from a study that evaluated trainings provided by a local Continuum of Care lead agency to homelessness assistance service providers. The study explored types of trainings desired by participants, benefits and drawbacks of existing trainings and how they are offered, and ways in which trainings and the training delivery system could be improved. Data were collected through semistructured focus groups attended by 21 providers. Data analysis identified themes related to specific trainings that, providers believe, would increase their effectiveness and improve organizational efficiency and culture. Participants also identified ways in which trainings were beneficial, but they also provided feedback about ways trainings could be improved.
Logarithmic confidence intervals for the cross-product ratio of binomial proportions under different sampling schemes

Abstract We consider the problem of logarithmic interval estimation for a cross-product ratio with data from two independent Bernoulli samples. Each sample may be obtained in the framework of direct or inverse Binomial sampling schemes. Asymptotic logarithmic confidence intervals are constructed under different types of sampling schemes, with parameter estimators demonstrating exponentially decreasing bias. Our goal is to investigate the cases when the relatively simple normal approximations for estimators of the cross-product ratio are reliable for constructing logarithmic confidence intervals. We use the closeness of the confidence coefficient to the nominal confidence level as our main evaluation criterion, and use the Monte-Carlo method to investigate the key probability characteristics of intervals corresponding to all possible combinations of sampling schemes. We present estimations of the coverage probability, expectation and standard deviation of interval widths in tables. Also, we provide some recommendations for applying each logarithmic interval obtained.
Experimentation Platforms as Bridges to Urban Sustainability

Despite immense efforts to realize diverse visions of the ‘smart city,’ municipalities still face manifold uncertainties of how governance and the tools of governance can best support public and regional value creation for achieving urban sustainability. To this end, Urban Living Labs have become a known enabling mechanism. In this paper, we extend the lab idea and formulate the concept of Urban Experimentation Platform that focuses on developing urban innovation ecosystems for urban sustainability. We use action design research and participant observation across multiple case studies enacting Urban Experimentation Platforms in order to investigate how the tie-in between governance and the local lab’s innovation process unfolds. Our analysis distills three facets that are instrumental in institutionalizing these platforms as resilient organizational models. With the help of the case studies, we illustrate the three facets, concerning issues of urban ecosystem governance, empowering co-creation, and qualifying local innovation. The facets reinforce the roles of digital instruments and digital capabilities for effective urban governance and platform management. We draw some conclusions for future research and formulate policy recommendations for implementing and operating Urban Experimentation Platforms.
Inhibition of transpiration in rice by prohydrojasmon compared with that by commercially available microcrystalline and paraffin wax agents

ABSTRACT Prohydrojasmon (PDJ), a synthetic derivative of the plant hormone jasmonic acid, has been identified as a plant growth regulator used in various fruit and rice seedlings. In this study, we demonstrate the inhibition of transpiration by PDJ in the indica rice cultivar cv. Takanari compared with commercially available microcrystalline and paraffin wax agents in a greenhouse. Microcrystalline and paraffin wax agents inhibited approximately 30%–50% transpiration 3 h after application, and the inhibition lasted for seven days after treatment, depending on the concentration and the agent used. In contrast, PDJ inhibited approximately 40%–80% transpiration compared with control 0.5 h after treatment, and the effect lasted for one day. However, the effect almost disappeared 7 days after treatment. Thus, PDJ affects transpiration differently than commercially available products and could be used to lower excess transpiration in rice, specifically when an early, transient, and reversible inhibition is needed.

Comparative Proteomics Analysis of Phosphine-Resistant and Phosphine-Susceptible Sitophilus oryzae (Coleoptera: Curculionidae)

A proteomic method combining two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) and matrix-assisted laser desorption/ionization-time-of-flight/time-of-flight mass spectrometry (MALDI-TOF/TOF) was used to compare the protein expression profiles of phosphine-resistant (PH3-R) and -susceptible (PH3-S) strains of Sitophilus oryzae. Thirty-nine differentially expressed protein spots were identified between the PH3-R and PH3-S strains; 20 protein spots were upregulated, and 19 protein spots were downregulated in the PH3-R strain compared with their expression in the PH3-S strain. In particular, cytochrome oxidase subunit I showed 15-fold higher expression in the PH3-R strain than in the PH3-S strain. Additionally, citrate synthase 2, delta-1-pyrolline-5-carboxylate dehydrogenase, and triose-phosphate isomerase were highly expressed in the PH3-R strain. In summary, our study has improved understanding of the molecular mechanisms of phosphine resistance in the rice weevil.
Understanding women's wage growth using indirect inference with importance sampling

Summary The goal of this work is to investigate the effects of time out of the labor market for childcare on women's lifecycle wage growth. We develop a dynamic lifecycle model of human capital, fertility, and labor supply for women. We estimate by indirect inference using importance sampling and formalize the use of this procedure. The results indicate a modest effect of fertility-induced non-employment spells on human capital accumulation. The difference in human capital among prime-age women would be approximately 2.4% higher at its peak if the relationship between fertility and working were eliminated, and 4.7% higher if the relationship between marriage and fertility was also eliminated.
Strategy and Uncertainty: Resource-Based View, Strategy-Creation View, and the Hybrid Between Them

The resource-based view (RBV) makes a significant contribution to strategy by explaining the relationship between resources and firm performance. Particularly in low uncertainty markets, executives have the foresight and time to build strategically valuable resources in current markets and leverage them into related markets. RBV is also relevant for understanding strategies for market entry, extending the value of technology resources, and broadening the locus of resources within ecosystems. Conversely, in high uncertainty markets like nascent or disrupted ones, RBV seems less germane. Resources may not yet exist or their value (and rarity) may be indeterminate (or changing). Here, we contribute the Strategy Creation (SC) view—joining strategizing by doing, thinking, and shaping. It offers a strategic logic that fits highly uncertain markets. Finally, we contribute the insight that RBV and SC are complements under moderate uncertainty, such as growth markets and technology transitions. Overall, we propose that uncertainty forms a crucial boundary condition for RBV that distinguishes between qualitatively different strategic logics.
Optimization of connection architectures and mass distributions for metamaterials with multiple resonators

Metamaterials with multiple resonators have been widely investigated for the purpose of generating multiple stop bands or broadening the attenuation bandwidth. The multiple resonators could be connected end to end in a line, namely, in-series connection, or connected individually to the host structures, namely, in-parallel connection. This paper investigates the influence of the resonator connection methodology on the frequency response functions of metamaterial beams with multiple resonators and exhibits an approach for optimizing their resonator distribution over the structure. The receptance functions of metamaterial beams with various resonator connection architectures are calculated by a transfer matrix model, which is verified through finite element model results. It is demonstrated that resonator interconnection architectures have a great impact on the global dynamic properties of metamaterials. An optimization strategy is subsequently proposed to find out the optimal resonator connection architectures and mass distributions that could minimize the maximal receptance functions in targeted single and multiple frequency ranges. The objective functions within single targeted frequency ranges are solved by the adoption of the genetic algorithm method. The weighted sum method is used to gain an optimal solution for multi-frequency range optimization. The metamaterial beams with optimal resonator connection methods and mass distributions demonstrate greatly enhanced vibration attenuation at frequencies of interest compared with other beams. The work is expected to provide the necessary theoretical basis and incentive for future researchers working on the design of metamaterials with extended, tuned, and optimized stop bands.
Preparation and Application of ZIF-8 Thin Layers

Herein we compare various preparation methods for thin ZIF-8 layers on a Cu substrate for application as a host material for omniphobic lubricant-infused surfaces. Such omniphobic surfaces can be used in thermal engineering applications, for example to achieve dropwise condensation or anti-fouling and anti-icing surface properties. For these applications, a thin, conformal, homogeneous, mechanically and chemically stable coating is essential. In this study, thin ZIF-8 layers were deposited on a Cu substrate by different routes, such as (i) electrochemical anodic deposition on a Zn-covered Cu substrate, (ii) doctor blade technique for preparation of a composite layer containing PVDF binder and ZIF-8, as well as (iii) doctor blade technique for preparation of a two-layer composite on the Cu substrate containing a PVDF-film and a ZIF-8 layer. The morphology and topography of the coatings were compared by using profilometry, XRD, SEM and TEM techniques. After infusion with a perfluorinated oil, the wettability of the surfaces was assessed by contact angle measurements, and advantages of each preparation method were discussed.

The role of organisational culture in organisational change towards sustainability: evidence from the garment manufacturing industry

Abstract This paper explores the competing role of organisational culture in organisational change towards sustainability. Drawing on the competing values framework, data was collected by interviewing senior executives and sustainability managers of a leading multinational garment manufacturing organisation based in Sri Lanka. The study finds that organisational culture tends to play a proactive role by going beyond the compliances and regulatory requirements in organisational change towards sustainability. Four competing cultural values appear to shape their corporate sustainability approach, namely (i) people-oriented changes (e.g. empowerment, training, development, team orientation, leadership), (ii) growth-oriented changes (e.g. sustainability innovations, continuous improvements, community engagement), (iii) productivity- and efficiency-oriented changes (e.g. use of professional recommendations, open communication), and (iv) stability- and control-oriented changes (e.g. sustainability budgeting, investment appraisal, life-cycle assessment). The case organisation is more likely to be driven by an integrated approach of the four competing cultural values rather than by one dominant approach. The study contributes to the organisational culture and sustainability literature by highlighting the importance of aligning competing cultural values as a means of addressing sustainability challenges, in the much-debated garment manufacturing industry in the South Asian context. Finally, a framework for sustainability organisational culture is proposed.
Low-Calorie Beverages Made from Medicinal Plants, Flowers and Fruits: Characteristics and Liking of a Population with Overweight and Obesity

Nowadays, there are few options of low or no added sugar drinks offering health benefits and oriented to consumers with a special health condition, such as overweight and obesity. The objective of this work was to develop and characterize a low-calorie antioxidant beverage made from aqueous extracts of medicinal plants (Melissa and lemon verbena), flowers (chamomile and bougainvillea), and fruits (guava, pineapple, strawberry, orange, and tangerine) as an alternative for people with overweight and obesity. Four formulations were developed from medicinal plants, flowers, and fruits. For this, a solid-liquid conventional extraction was carried out (at 90 °C during 5 min) followed by a cold shock in ice. The developed beverages were characterized in a microbiological and physicochemical way according to official analysis methods. The sensory evaluation was carried out through liking and buying intention tests. The population under study was integrated by 400 adults divided into two groups (with and without overweight or obesity). The beverages developed were low-calorie (≤40 kcal per portion), very low in sodium (<34 mg per portion), rich in antioxidants (>1.6 g GAE portion), and with an attractive color. The results indicate that these beverages could be an alternative to the consumption of common industrialized drinks conferring additional benefits for the prevention of chronic diseases.
PVTOL global stabilisation using a nested saturation control

This paper presents how the nested saturation control introduced in Teel (1992) can be modified to stabilise the model of the Planar Vertical Take-Off and Landing (PVTOL) system. A particular choice of the amplitudes of the nested saturations controller is given such that global stability of the closed loop system is obtained. The proof is given in detail. Numerical simulations illustrate the performance of the proposed control algorithm.
Phase-Controlled Planar Metalenses for High-Resolution Terahertz Focusing

We experimentally demonstrate that high-resolution terahertz focusing can be realized in planar metalenses, which consist of arrays of different V-shaped antenna units on a silicon substrate. Numerical results show that a larger numerical aperture of metalenses can provide smaller full width at half maximum of field distribution, leading to higher spatial resolution. The measurement of fabricated metalenses samples was performed by a terahertz near-field imaging system, and experimental results agree well with the numerical prediction. Especially for 1.1 THz incident light, when the numerical aperture increases from 0.79 to 0.95, the full width at half maximum correspondingly decreases from 343 μm to 206 μm, offering an improvement of spatial resolution.
Method for inferring the mechanical strain of GaN-on-Si epitaxial layers using optical profilometry and finite element analysis

GaN-on-Si has become a useful fabrication route for many GaN devices and applications, but the mechanical stress incorporated throughout the material stack can impact the viability of this approach. The transfer printing of GaN membrane devices, a promising emerging technology, is most effective with flat membranes, but in practice many GaN structures released from their Si substrate are highly bowed due to the strain in the epitaxial nitride stack. Our approach uses the optical profiles of epitaxial wafers and membranes as inputs for inferring the mechanical strain state of the material by multi-variable numerical model fitting using COMSOL Multiphysics. This versatile, adaptable and scalable method was tested on samples from two GaN-on-Si wafers, revealing the relationship between built-in strain and material bow in principal-component fashion, returning 3–4×10−4 strain estimates for the AlGaN (compressive) and GaN (tensile) layers, and suggesting the occurrence of plastic deformation during transfer printing.
