Customer Satisfaction Towards Food Service Apps in Indian Metro Cities

Abstract The appearance of the internet, together with the development of related advancements, has made a noteworthy effect on the lives of individuals around the world. For advertisers, a standout among the various effects has been the rise of virtual stores that sell items and administrations online. Consumers are now be able to buy products and ventures for all intents and purposes anywhere, 24 hours daily, 7 days and without land and fleeting limits. While numerous advertisers recognize the significance of utilizing the internet in their promoting blends, little research has exactly tried the basic factors that impact a person’s choice when purchasing items or administrations on the web. This investigation looks at the determinants of the client-requesting knowledge, which incorporates information quality of the app, payment system and design of the app, customer services, customer satisfaction and the quality of food. The levels of determinants are indicated site quality and administration quality. Study information of 369 online sustenance-requesting clients was used to test the examination display, utilizing multiple regression analysis. Results uncover that not exclusively is there a huge positive relationship between customer services and satisfaction, yet additionally a huge positive relationship between quality of food and consumer satisfaction. Moreover, huge positive connections are additionally found not just between the app and consumer satisfaction but in addition between services and satisfaction also. There is a negative and insignificant connection between design of the app and satisfaction. By and large, the examination gives important bits of knowledge for working on web sustenance-requesting administrations effectively.
The Impact of Mobile Telecommunication Services on Students’ Lives: Findings from a Comparative Study in South Africa and Nigeria

The advancement in telecommunication network and computer based communication is of great importance in global communications, especially on young adults that constitute the sample of the study. In most mobile telecommunication services, quality is ascertained during the service delivery and not prior to the delivery of service making it to offer various services that is of interest to young people. These services are used to create and maintain social interactions while also depending on it for educational activities. This paper is based on empirical research to examine the impact of mobile telecommunications services on first-year Information Technology (IT) students at Lagos State University (LASU), Lagos, Nigeria and University of KwaZulu-Natal (UKZN) Durban, South Africa. The study enables the understanding of the quality of services required to identify students’ experiences and perceptions of mobile telecommunication services and the effect it has on their academic and social life.
A Cascade-Classifier Approach for Fall Detection

The current machine learning algorithms in fall detection, especially those that use a sliding window, have a high computational cost because they need to compute the features from almost all samples. This computation causes energy drain and means that the associated wearable devices re- quire frequent recharging, making them less usable. This study proposes a cascade approach that reduces the computational cost of the fall detection classifier. To examine this approach, accelerometer data from 48 subjects performing a combination of falls and ordinary behaviour is used to train 3 types of classifier (J48 Decision Tree, Logistic Regression, and Multilayer Perceptron). The results show that the cascade approach significantly reduces the computational cost both for learning the classifier and executing it once learnt. Furthermore, the Multilayer Perceptron achieves the highest performance with precision of 93.5%, recall of 94.2%, and f-measure of 93.5%.
Innovation in the UK fresh produce industry : sources, barriers and innovative capacity

The UK fresh produce industry faces a number of challenges, including new pests and diseases, foreign competition and the cost of and access to seasonal labour. ‘Innovation’ has been promoted to meet these challenges, but the sources of innovation, and what holds it back, have not been explored. This thesis aims to: 1) identify the sources of innovation in the fresh produce industry, 2) determine the barriers to innovation in the industry and 3) seek ways to improve the overall innovative capacity of the sector. It does so by using the Agricultural Innovation Systems (AIS) approach as an underpinning framework within a case study design. 32 industry practitioners, including growers, technologists, researchers and retailers took part in semi-structured interviews, which were analysed using Framework Analysis. The study finds an increasingly consolidated and competitive industry, influenced heavily by retail groups and the need for constant innovation. It describes ‘types’ of innovation and their interlinked nature, as well as the inherent uncertainty around innovation and the difficulties in ‘measuring’ change. It finds that innovation often originates overseas and through experimentation or interaction with a given product or process. It describes both positive and negative communication in the industry and explores other blocking mechanisms to innovation including horizontal and vertical fragmentation, diverging innovation agendas and a “defensive” innovation culture. It also identifies a number of enabling factors for change. Interactivity and network formation are recognised as vital components of the innovation system. However, considerable emphasis is placed on non-systemic factors, such as entrepreneurialism. These findings are combined with existing literature in a functional-structural analysis to offer recommendations to bolster innovative capacity in the industry. The study makes several original contributions to knowledge, particularly with respect to the AIS approach: that innovation systems routinely extend beyond national borders, facilitated in part by another understudied issue – producer organisations – is an area for further research.
Effectiveness of Schools’ Management and Its Measurement – a Review of Concepts

Purpose – Identification of factors determining the effectiveness of public schools’ management, and the establishment of means for developing the concept of measuring the schools’ effectiveness. Methodology – Review and assessment of concepts and studies present in Polish and international literature pertaining to the evaluation of public schools’ effectiveness. Findings – The hitherto methods for evaluating schools are unsatisfactory. It is largely associated with ambiguous definitions of schools’ effectiveness and identification of objectives and tasks schools are to achieve and undertake, associated with it. This, in turn, results from the fact that effectiveness assessment may by defined differently by various stakeholders. However, the measurement of effectiveness is necessary due to the fact that it facilitates the emergence of high quality educational services in Polish public schools. Research implications – The review of literature indicates that the assessment of educational added value over the course of several years of education seems valid. This means that rather than tracking final results achieved by students, the growth of students’ knowledge ought to be measured. The Data Envelopment Analysis (DEA) method may be helpful in relation to the above. The method seems well-suited for evaluating the effectiveness of NGO sector institutions, and takes non-financial factors into consideration, which will enable methodologically categorized knowledge on the effectiveness of schools’ management to be obtained. Practical implications – Results of the present study may be applied by institutions supervising public schools and by individuals who manage these institutions in order to perform periodic assessments of schools’ effectiveness, and who would stimulate the education quality improvement. Social implications – Results of the present study may foster the improvement of schools’ competitiveness and improvement of their educational actions’ quality. Originality/ Value – The paper supplements knowledge regarding the assessment of Polish public schools’ effectiveness. Type of article – A theoretical paper.
Fine mapping of ZNF 804 A and genome-wide significant evidence for its involvement in schizophrenia and bipolar disorder

A recent genome wide association study reported evidence for association between rs1344706 within ZNF804A (encoding zinc finger protein 804A) and schizophrenia (P=1.61 ×10−7), and stronger evidence when the phenotype was broadened to include bipolar disorder (P=9.96 ×10−9). Here we provide additional evidence for association through meta-analysis of a larger dataset (schizophrenia/schizoaffective disorder N = 18945, schizophrenia plus bipolar disorder N =21274, *corresponding authors; Michael C O’Donovan and Michael J Owen, MRC Centre for Neuropsychiatric Genetics and Genomics, Henry Wellcome Building, Department of Psychological Medicine and Neurology, School of Medicine, Cardiff University, Cardiff, CF14 4XN, UK.

Author manuscript; available in PMC 2014 February 10. Published in final edited form as: Mol Psychiatry. 2011 April ; 16(4): 429–441. doi:10.1038/mp.2010. 36. N IH PA Athor M anscript N IH PA Athor M anscript N IH PA Athor M anscript controls N =38675). We also sought to better localize the association signal using a combination of de novo polymorphism discovery in exons, pooled de novo polymorphism discovery spanning the genomic sequence of the locus and high density LD mapping. Meta-analysis provided evidence for association between rs1344706 that surpasses widely accepted benchmarks of significance by several orders of magnitude for both schizophrenia (P=2.5 ×10−11, OR=1.10, 95% CI 1.07–1.14) and schizophrenia and bipolar disorder combined (P=4.1 ×10−13, OR=1.11, 95% CI 1.07–1.14). After de novo polymorphism discovery and detailed association analysis, rs1344706 remained the most strongly associated marker in the gene. The allelic association at the ZNF804A locus is now one of the most compelling in schizophrenia to date, and supports the accumulating data suggesting overlapping genetic risk between schizophrenia and bipolar disorder.
Taxonomy-Based Approaches to Quality Assurance of Ontologies

Ontologies are important components of health information management systems. As such, the quality of their content is of paramount importance. It has been proven to be practical to develop quality assurance (QA) methodologies based on automated identification of sets of concepts expected to have higher likelihood of errors. Four kinds of such sets (called QA-sets) organized around the themes of complex and uncommonly modeled concepts are introduced. A survey of different methodologies based on these QA-sets and the results of applying them to various ontologies are presented. Overall, following these approaches leads to higher QA yields and better utilization of QA personnel. The formulation of additional QA-set methodologies will further enhance the suite of available ontology QA tools.
Integrating Third Parties in Digitally Mature Companies: Determinants of Innovation Success

We develop and empirically analyse a theoretical model that examines both the antecedents of digital maturity and the involvement of external third parties in companies undergoing digital transformation. We use structural equation modelling technique to test our propositions using the survey data from IT executives on self-reported importance scores they assign to different types of IT competences. We find that digitally mature companies are more likely to establish partnerships with the third parties with a purpose of jointly carrying out digital innovation projects.

The Survival Benefits of Service Intensity for New Manufacturing Ventures: A Resource-Advantage Theory Perspective

We investigate the association between service intensity and the survival odds of new manufacturing ventures. Although previous research extensively addresses the value of servitization in established firms, this is the first empirical study that asks whether service intensity, defined as the percentage of sales from services, is beneficial or detrimental to new ventures. Drawing on resource-advantage theory, we further ask whether, under increasing service intensity, new ventures with a higher industry-adjusted ratio of tangible to total assets, labor productivity, or current ratio improve survival odds. Based on a comprehensive data on 6,683 new Portuguese manufacturing ventures founded between 2006 and 2010 and followed until 2015 (33,272 venture-year observations), the results show that higher service intensity lowers the odds of survival. For entrepreneurs, we caution against higher service intensity but demonstrate that survival odds can improve under increasing service intensity when the company can achieve a higher industry median–adjusted ratio of tangible to total assets, improved labor productivity, or a stronger current ratio position. The findings are robust after controlling for endogeneity and self-selection into services.
Adaptive Neural Output Feedback Control of Uncertain Nonlinear Systems With Unknown Hysteresis Using Disturbance Observer

In this paper, an adaptive neural output feedback control scheme is proposed for uncertain nonlinear systems that are subject to unknown hysteresis, external disturbances, and unmeasured states. To deal with the unknown nonlinear function term in the uncertain nonlinear system, the approximation capability of the radial basis function neural network (RBFNN) is employed. Using the approximation output of the RBFNN, the state observer and the nonlinear disturbance observer (NDO) are developed to estimate unmeasured states and unknown compounded disturbances, respectively. Based on the RBFNN, the developed NDO, and the state observer, the adaptive neural output feedback control is proposed for uncertain nonlinear systems using the backstepping technique. The first-order sliding-mode differentiator is employed to avoid the tedious analytic computation and the problem of “explosion of complexity” in the conventional backstepping method. The stability of the whole closed-loop system is rigorously proved via the Lyapunov analysis method, and the satisfactory tracking performance is guaranteed under the integrated effect of unknown hysteresis, unmeasured states, and unknown external disturbances. Simulation results of an example are presented to illustrate the effectiveness of the proposed adaptive neural output feedback control scheme for uncertain nonlinear systems.
Is a fully heparin-bonded cardiopulmonary bypass circuit superior to a standard cardiopulmonary bypass circuit?

A best-evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was 'Is a fully heparin bonded cardiopulmonary bypass circuit superior to a standard cardiopulmonary bypass circuit? ' Altogether more than 792 papers were found using the reported search, of which 13 represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated (Table 1). The studies analysed show that perfusion with heparin-coated and heparin-polymer-coated bypass does not increase the risk of adverse effects but reduces blood loss, re-operation rates, ventilation time, length of intensive care unit (ICU) and hospital stay and is also associated with improved biocompatibility, as evidenced by platelet preservation, reduced leucocyte and complement activation, and proinflammatory cytokine production. The various coated circuits have comparable biocompatibility as evaluated by a range of inflammatory markers and clinical outcomes. Three studies documented a significant decrease in post-operative blood loss (P = 0.001-0.54) and a meta-analysis found that perfusion with a heparin-bonded circuit resulted in a reduction in blood transfusion requirements (20%), ventilation time (P < 0.01), length of time in the ICU (P < 0.01) and also hospital stay (P = 0.02). Two studies found reduced levels of polymorphonuclear elastase (P < 0.018-0.001) and two trials concluded that the use of heparin-coated circuits in combination with low-dose systemic heparin (activated clotting time >250) resulted in the greatest clinical benefit and improvement in inflammation. One study documented significant platelet preservation with the use of third-generation heparin-polymer-bonded circuits (P ≤ 0.05). We conclude that despite heparin-bonded and newer third-generation heparin-polymer-bonded cardiopulmonary bypass circuits having a greater cost per person, their improved clinical outcomes and biocompatibility in patients undergoing cardiac surgery make them a preferable option to standard non-heparin-bonded circuits.
Surgical robotics and laparoscopic training drills.

PURPOSE We investigated the impact of robotics on surgical skills by comparing traditional laparoscopy with the da Vinci Surgical System in the performance of various laparoscopic training drills. SUBJECTS AND METHODS Twenty-one surgeons performed eight timed drills of increasing difficulty with a laparoscopic trainer and the da Vinci Surgical System (Intuitive Surgical Sunnyvale, CA). The mean time to drill completion, drill time variance, and statistical analysis were performed. Surgeons were also questioned about their perception of the robotic technology following completion of the drill series. RESULTS The mean time required to complete the first drill was 69 seconds with laparoscopy and 57 seconds with the robotic system. The mean times for drill two were 67 seconds with laparoscopy and 44 seconds with robotics; for drill three, the times were 88 seconds for laparoscopy and 61 seconds for robotics, and for drill four, 186 seconds with laparoscopy and 71 seconds with robotics. Only the first drill failed to show a statistically significant difference between the laparoscopic and robotic groups. CONCLUSIONS The robotic system allowed surgeons to complete drills faster than traditional laparoscopy. Novice laparoscopic surgeons performed three of the four drills faster robotically than did expert laparoscopic surgeons. These findings may indicate that the attributes of the robotic system level the playing field between surgeons of different skill levels. The next generation of surgeons must focus on this evolving technology and its application in the operating room of the future.
Bergenin, Acting as an Agonist of PPARγ, Ameliorates Experimental Colitis in Mice through Improving Expression of SIRT1, and Therefore Inhibiting NF-κB-Mediated Macrophage Activation

Bergenin, isolated from the herb of Saxifraga stolonifera Curt. (Hu-Er-Cao), has anti-inflammatory, antitussive and wound healing activities. The aim of the present study was to identify the effect of bergenin on experimental colitis, and explored the related mechanisms. Our results showed that oral administration of bergenin remarkably alleviated disease symptoms of mice with dextran sulfate sodium (DSS)-induced colitis, evidenced by reduced DAI scores, shortening of colon length, MPO activity and pathologic abnormalities in colons. Bergenin obviously inhibited the mRNA and protein expressions of IL-6 and TNF-α in colon tissues, but not that of mucosal barrier-associated proteins occludin, E-cadherin and MUC-2. In vitro, bergenin significantly inhibited the expressions of IL-6 and TNF-α as well as nuclear translocation and DNA binding activity of NF-κB-p65 in lipopolysaccharide (LPS)-stimulated peritoneal macrophages and RAW264.7 cells, which was almost reversed by addition of PPARγ antagonist GW9662 and siPPARγ. Subsequently, bergenin was identified as a PPARγ agonist. It could enter into macrophages, bind with PPARγ, promote nuclear translocation and transcriptional activity of PPARγ, and increase mRNA expressions of CD36, LPL and ap2. In addition, bergenin significantly up-regulated expression of SIRT1, inhibited acetylation of NF-κB-p65 and increased association NF-κB-p65 and IκBα. Finally, the correlation between activation of PPARγ and attenuation of colitis, inhibition of IL-6 and TNF-α expressions, NF-κB-p65 acetylation and nuclear translocation, and up-regulation of SIRT1 expression by bergenin was validated in mice with DSS-induced colitis and/or LPS-stimulated macrophages. In summary, bergenin could ameliorate colitis in mice through inhibiting the activation of macrophages via regulating PPARγ/SIRT1/NF-κB-p65 pathway. The findings can provide evidence for the further development of bergenin as an anti-UC drug, and offer a paradigm for the recognization of anti-UC mechanisms of compound with similar structure occurring in traditional Chinese medicines.
