The role of self-efficacy and customer satisfaction in driving loyalty to the mobile shopping application

The purpose of this paper is to develop and empirically test a model that examines the relationship between post-adoption self-efficacy, satisfaction, and loyalty in the usage of mobile shopping applications. ,A structured questionnaire was used to collect data from respondents who had used mobile shopping applications to make purchases. Data analysis was done using partial least square structural equation modelling. ,The results show that self-efficacy and satisfaction have a positive impact on continuance intention; however, the same may not lead to advocacy. The results also show that some antecedents of self-efficacy and satisfaction at the post-adoption stage differ from the pre-adoption intention stage. ,The findings of the study provide a better understanding of the factors likely to influence loyalty among customers using mobile shopping applications. The findings also provide valuable insights into the factors that e-retailers need to focus to build self-efficacy among their customers using mobile interface. ,The contribution of the paper lies in eliciting the differences between customer choice model at the pre-adoption and post-adoption stage for mobile shopping. Furthermore, the study demonstrated the role of a cognitive factor of self-efficacy in loyalty at the post-adoption stage that is pre-dominantly researched with affective factor of satisfaction.
Folate: a magic bullet or a double edged sword for colorectal cancer prevention?

Low folate status might inhibit colorectal carcinogenesis and high folate status may promote colorectal carcinogenesis, contradicting findings from epidemiological studies showing an inverse relationship between folate status and risk of colorectal cancer Folate is a water soluble B vitamin, deficiency of which appears to play an important pathogenetic role in the development of anaemia, atherosclerosis, neural tube defects (NTDs), adverse pregnancy outcomes, neuropsychiatric disorders, and cancer.1 Folic acid is the fully oxidised monoglutamyl form of this vitamin that is used commercially in supplements and in fortified foods. Folate is generally regarded as safe and has long been presumed to be purely beneficial and an ideal functional food component for disease prevention.2,3 For example, an overwhelming body of evidence for a protective effect of periconceptional folic acid supplementation against NTDs led to mandatory folic acid fortification in the USA and Canada in 1998.4 The effectiveness of folic acid fortification in improving folate status has already been shown to be quite striking, with a dramatic increase in blood measurements of folate concentrations in the USA and Canada.4 Preliminary reports also suggest a significant reduction (∼15–50%) in the incidence of NTDs in the USA and Canada.4 Perhaps one of the most speculative and provocative new medical applications of folate nutrition is the potential role of folate as a cancer preventive agent.1,5 The concept that folate deficiency enhances, whereas folate supplementation reduces, the risk of neoplastic transformation appears counterintuitive and contradictory to our conventional understanding of folate biochemistry. Folate is an essential cofactor for the de novo biosynthesis of purines and thymidylate, and in this role folate plays an important role in DNA synthesis and replication.5,6 Consequently, folate deficiency in tissues with rapidly replicating cells results in ineffective DNA synthesis. In neoplastic cells where …
The Effect of Trust in Adoption of Internet Banking: A case study of Nigeria.

The concept of trust in the domain of internet banking has received a significant rate of interest and was recognized by researchers as one of the key motive why a large percentage of consumers are still reluctant to accept Internet banking, most especially in developing countries and Nigeria in particular. There is imbalance in the methodology and analysis of internet banking as the majority of the study in this field adopts quantitative methodology. There is little qualitative research that investigates the effect of trust in adoption of internet banking from the customers’ perspective. This paper aimed to explore qualitatively the effect of trust on adoption and usage of internet banking. This study analyzed the data that was drawn through interviews with 40 bank customers in Nigeria. The four themes that emerged from the data in this study show that Nigerian customers lack trust in internet banking because of security issue, bank reputation, information technology and institution based trust.

The Impact of Oil Price Fluctuations on Industry Stock Returns: Evidence from International Markets

This study investigates the impact of oil price variation on 14 industries in six markets, including Canada, China, France, India, the United Kingdom, and the United States. Panel weekly data were collected from June 1998 to December 2011. The results indicate that price fluctuations primarily affect the Oil and Gas as well as the Mining industries and have the least influence on the Food and Beverage industry. Furthermore, in three out of six of these countries (Canada, France, and the U.K.), oil price changes negatively affect the Pharmaceutical and Biotechnology industry. One possible reason for the negative relationship between oil price changes and the Pharmaceutical and Biotechnology industries in the above-mentioned countries is that the governments of these countries fund their healthcare systems. Portfolio managers and investors will find the results of this study useful because it enables adjusting portfolios based on knowledge of the industries that are impacted the most or the least by oil price fluctuations.
Distribution of lipids and trace minerals in different muscle sites of farmed and wild turbot (Psetta maxima)

Summary Lipid and trace mineral composition were studied in different sites of the edible flesh of farmed and wild turbot (Psetta maxima). Lipid matter (total content, sterols, tocopherols) showed to accumulate in the edge zone (EZ), except for phospholipid (PL), which provided a distribution that was found to be independent from the kind of turbot and the zone considered. Fatty acid composition of total lipids showed a non-homogeneous distribution, as the EZ exhibited a different fatty acid group composition (higher monounsaturated and lower polyunsaturated and ω3/ω6 ratio values) than the other zones considered; fewer differences were observed by considering the PL fatty acid composition. Most minerals (Ca, Cu, Fe, Mn and Se) studied showed to be homogeneously distributed along the muscle sites of the wild fish, while more differences were obtained when considering the farmed one. For both kinds of turbots, the most important difference was obtained in the case of Zn, as a largely higher content in the EZ than in the other zones was detected. A close relationship between Zn and total lipid contents (r2 = 0.90 and 0.76 for farmed and wild turbots, respectively) was observed.
Why Should I Switch Off: Understanding the Barriers to Sustainable Consumption?

This study identifies the barriers to sustainable consumption and measures the discriminating power of these barriers between groups having significant differences in their energy conservation behaviour. By analysing the response of 321 consumers to questionnaire survey in India, results reveal that belief in material growth is found to be the most important factor associated with the energy conservation behaviour across levels (grey, grey-green and green energy consumers). However, belief in technology is negatively associated with energy conservation efforts to all consumers. However, cynicism does not relate to energy conservation efforts. The results are significant to the agencies designing energy conservation campaigns aimed at modifying energy consumption behaviour of domestic consumers.
Stroke in CT-scan Department of Khartoum Hospital, Sudan

Prospective data were collected on consecutive patients admitted to Khartoum Teaching Hospital with a diagnosis of stroke. Risk factors and clinical characteristics were assessed by neurological examination and computed tomography scan. A total of 128 patients were enrolled in the study, of whom 74 (57.8%) were men. The age (mean±standard deviation) of the patients was 53±18.5 years. Eighty-five (66.4%) and 43 (33.6%) patients had ischaemic and haemorrhagic stroke, respectively. Hypertension, diabetes mellitus, smoking, heart disease and hypercholesterolaemia were the risk factors for stroke. Thus, further studies are needed on stroke. Hypertension should be discovered early and treated effectively.
Earnings Management Surrounding Takeover Rumours

I investigate whether firms manage earnings in proximity to initially published rumours of their impending takeover. Utilizing a unique sample of 1,831 takeover rumours, I find that rumoured target firms inflate their earnings prior to the rumour's publication. Rumours which are more likely to be anticipated by the target firm (rumours initiated by targets, rumours concerning financial distress, and rumours concerning the hiring of a financial advisor) provide stronger associations with earnings management than do other rumour types. I interpret results as consistent with rumored target firms attempting to benefit from higher takeover valuations if takeover bids are indeed forthcoming
Analysis of Information Systems Capabilities and Performance of Firms in Telecommunications Industry, Kenya

In the 21st century where economies are driven majorly by knowledge and information-based service businesses, telecommunication industries are playing a critical economic role both regionally and globally. In Kenya, with a combined subscription rate of 37.8 million based on a 2016/17 Communication Authority of Kenya report of 2017, Safaricom Kenya Limited controls about 71.2% of the subscribers, Airtel Kenya Limited is second with 17.6% with Telkom Kenya coming third with 7.4%. Finserve East Africa (Equitel) a new entrant in the market controls 3.8% of subscribers. These figures points to the fact that only Safaricom seems to be the only firm performing well. This reality forms the basis of establishing whether their difference in performance is attributable to their information systems capabilities. The purpose of this study was to analyse the relationship IS capabilities and performance of firms in the telecommunications industry in Kenya. It was anchored on Resource-Based Theory and guided by a conceptual framework with the dependent variable being firm performance while independent variable was IS capabilities. Correlational and survey research designs were used. The population of the study was 408 staff comprising all executive, management and operational level managers from the business and IT sections in each firm. A sample of 202 staff was drawn through proportionate stratified random sampling method. Primary data was collected using structured questionnaire and an interview schedule. Reliability of the research instrument was tested against Cronbach’s alpha coefficient where a reliability score of 0.814 was achieved while validity was gauged through research experts’ opinions. Data was analysed using both descriptive and inferential statistics. The findings established that IS capabilities and firm performance have a weak relationship (r = 0.409, p<0.05) which means that whenever firms in industry invested on market based IS capabilities there was a small improvement on their performance and therefore firms should invest in the development of market based IS capabilities since they have significant influence on their performance. This study may be useful to industry players by gaining better understanding on various information system resources that they can utilize to improve and sustain their performance besides policy formulation. By advancing a model that depicts the relationship between information systems resources and firm performance, this study may make a significant contribution to theory building in the field of information systems.
Clinical Application of Multicolor Imaging Technology

Purpose: To assess the clinical application of multicolor imaging by confocal scanning laser ophthalmoscopy (cSLO). Methods: Retinal imaging was performed in 76 patients including cSLO multicolor imaging (SPECTRALIS SD-OCT, Heidelberg Engineering, Heidelberg, Germany) and color fundus photography (CFP). Results: The use of confocal optics, reduced light scatter and automated eye tracking enable high-resolution cSLO reflectance images. Compared to CFP, the appearance of pigment alterations and hemorrhages were some of the differences observed. Various artifacts including those derived from optical media alterations need to be considered when interpreting images. Specific pathological findings including epiretinal membranes, fibrovascular proliferations, and reticular pseudodrusen may be better visualized on multicolor images. Conclusions: When using multicolor imaging, ophthalmologists need to be mindful about differences in the appearance of pathological changes and artifacts. Multicolor imaging may offer information over and above conventional CFP; it can be performed through undilated pupils and is less affected by media opacities.
Diffusion-Weighted Intravoxel Incoherent Motion Imaging of Renal Tumors With Histopathologic Correlation

PurposeThe aim of this study was to use intravoxel incoherent motion diffusion-weighted imaging to discriminate subtypes of renal neoplasms and to assess agreement between intravoxel incoherent motion (perfusion fraction, fp) and dynamic contrast-enhanced magnetic resonance imaging (MRI) metrics of tumor vascularity. Subjects and MethodsIn this Health Insurance Portability and Accountability Act–compliant, institutional review board–approved prospective study, 26 patients were imaged at 1.5-T MRI using dynamic contrast-enhanced MRI with high temporal resolution and diffusion-weighted imaging using 8 b values (range, 0-800 s/mm2). Perfusion fraction (fp), tissue diffusivity (Dt), and pseudodiffusivity (Dp) were calculated using biexponential fitting of the diffusion data. Apparent diffusion coefficient (ADC) was calculated with monoexponential fit using 3 b values of 0, 400, and 800 s/mm2. Dynamic contrast-enhanced data were processed with a semiquantitative method to generate model-free parameter cumulative initial area under the curve of gadolinium concentration at 60 seconds (CIAUC60). Perfusion fraction, Dt, Dp, ADC, and CIAUC60 were compared between different subtypes of renal lesions. Perfusion fraction was correlated with CIAUC60. ResultsWe examined 14 clear cell, 4 papillary, 5 chromophobe, and 3 cystic renal cell carcinomas (RCCs). Although fp had higher accuracy (area under the curve, 0.74) for a diagnosis of clear cell RCC compared with Dt or ADC, the combination of fp and Dt had the highest accuracy (area under the curve, 0.78). The combination of fp and Dt diagnosed papillary RCC and cystic RCC with 100% accuracy, and clear cell RCC and chromophobe RCC, with 86.5% accuracy. There was significant strong correlation between fp and CIAUC60 (r = 0.82; P < 0.001). ConclusionIntravoxel incoherent motion parameters fp and Dt can discriminate renal tumor subtypes. Perfusion fraction demonstrates good correlation with CIAUC60 and can assess degree of tumor vascularity without the use of exogenous contrast agent.
Computationally Mapping Sequence Space To Understand Evolutionary Protein Engineering

Evolutionary protein engineering has been dramatically successful, producing a wide variety of new proteins with altered stability, binding affinity, and enzymatic activity. However, the success of such procedures is often unreliable, and the impact of the choice of protein, engineering goal, and evolutionary procedure is not well understood. We have created a framework for understanding aspects of the protein engineering process by computationally mapping regions of feasible sequence space for three small proteins using structure‐based design protocols. We then tested the ability of different evolutionary search strategies to explore these sequence spaces. The results point to a non‐intuitive relationship between the error‐prone PCR mutation rate and the number of rounds of replication. The evolutionary relationships among feasible sequences reveal hub‐like sequences that serve as particularly fruitful starting sequences for evolutionary search. Moreover, genetic recombination procedures were examined, and tradeoffs relating sequence diversity and search efficiency were identified. This framework allows us to consider the impact of protein structure on the allowed sequence space and therefore on the challenges that each protein presents to error‐prone PCR and genetic recombination procedures.
Multi-objective compact differential evolution

A wide range of problems in engineering require the simultaneous optimization of several objectives. Given the nature of such problems, it is often the case that the optimization process needs to take place from a device with very limited resources. Compact algorithms are a suitable alternative for being implemented in devices with limited computing resources, but so far, they have been used only to solve single-objective optimization problems. Here, we present a multi-objective compact algorithm based on differential evolution. The proposed algorithm obtains competitive results (and even better in some cases) than state-ofthe- art multi-objective evolutionary algorithms while using less memory resources because of its statistical representation of the population.
Shigella flexneri regulates tight junction‐associated proteins in human intestinal epithelial cells

Shigella spp. are a group of Gram‐negative enteric bacilli that cause acute dysentery in humans. We demonstrate that Shigella flexneri has evolved the ability to regulate functional components of tight junctions after interaction at the apical and basolateral pole of model intestinal epithelia. In the regulation of tight junctional protein assemblies, S. flexneri can engage serotype‐specific mechanisms, which targets not only expression, but also cellular distri‐bution and membrane association of components of tight junctions. Distinct mechanisms resulting in the regulation of tight junction‐associated proteins are initiated after either apical or basolateral interactions. S. flexneri serotype 2a has the ability to remove claudin‐1 from Triton X‐insoluble protein fractions upon apical exposure to T‐84 cell monolayers. S. flexneri serotype 2a and 5, but not the non‐invasive Escherichia coli strain F‐18, share the ability to regulate expression of ZO‐1, ZO‐2, E‐cadherin and to dephosphorylate occludin. The disruption of tight junctions is dependent on direct interaction of living Shigella with intestinal epithelial cells and is supported by heat‐stable secreted bacterial products. Intestinal epithelial cells have the ability to compensate in part for S. flexneri induced regulation of tight junction‐associated proteins.
The use of CellaVision™ DM96 in the verification of the presence of blasts in samples flagged by the Sysmex XE‐5000

The CellaVision™DM96 is a digital pattern recognition system that classifies white blood cells. The aim of this study was to evaluate whether the CellaVision preclassification feature, without a subsequent re‐classification, was a sufficient approach to follow up flags reported by Sysmex XE‐5000.
Distribution of Carabid Beetles (Coleoptera: Carabidae) Across Ecotones Between Regenerating and Mature Forests in Southwestern China

ABSTRACT Edge effects resulting from logging on the distribution of carabid beetles (Coleoptera: Carabidae) were studied across ecotones between regenerating and mature forests established after harvesting of old-growth forests 20 yr prior to this study in southwestern China. Using pitfall traps, beetles were collected along five ecotone transects using nine samples with a distance interval of 25 m each. Although no significant differences were found in species richness and abundance of carabids among all three habitats, i.e., mature forest, young regenerating stand, and edge habitat, rarefaction estimates of species richness indicated that traps in young regenerating stands accumulated species faster than those on mature forest interiors and forest edges. Carabid species composition of the forest edges was more similar to those of the mature forest interiors than to those of the young regenerating stands. Variability in species composition was significantly reduced in young stands, suggesting that the carabid community from young stands is more homogeneous than the one from mature forests. Although most species occurred in all habitats, some species were significantly more abundant in mature forests and/or edges than in young stands. Results indicated that edge effects on forest carabids may persist for at least 20 yr after disturbance.
