Trends in eBusiness and eGovernment

Technology affects all areas. Business and government processes are changing with the use of the internet, mobile devices, internet of things, blockchain, machine learning, artificial intelligence and many other new technologies. In this book, it is aimed to focus the use of technology, new trends in business life and government covering the studies in all sub-areas of Information Systems, Knowledge Management, eBusiness, eCommerce, eMarketing, mCommerce, eGovernment, ePublic Services, eGovernance etc. The book consists of 7 chapters. Book chapter authors are reputable scientists from different countries of the world. The first chapter is a critical review and a case study in e-Business, with special attention to the digital currencies resource and its possibilities. The second chapter attempts to incorporate the Unified Theory of Acceptance and Use of Technology (UTAUT) model with perceived risk theory (security risk and privacy risk) to explore its impact towards the intention to use m-government services. The third chapter aims to assess the level of gender inclusivity in the municipal e-procurement processes in the City of Johannesburg as a case study. The fourth chapter examines the impediments that derail the intensive uptake of eLearning programmes in a particular higher education institution. The fifth chapter investigated the role of Knowledge Management Systems (KMS) in enhancing the export performance of firms operating within the manufacturing sector in Zimbabwe. In the sixth chapter, a survey was undertaken on 131 small and medium-sized enterprises (SMEs) from Pelagonija region in order to determine the current level of SME digitalization within the region. It is aimed to compare with European Union (EU) average and to make conclusions on the impact of the SME digitalization to region gross domestic product (GDP) growth as well as revenues collection. The last chapter's purpose was to develop a measuring and modelling framework/instrument of Internet banking service quality (IBSQ) for the South African banking sector

Community Perspectives on Social Influences on Suicide Within a Native American Reservation

Relative to the general population, Native Americans (NA) bear a disproportionate burden of suicide-related mortality rates. NA males and females aged 15 to 24 years experience suicide rates nearly 3 times than the U.S. all races rates in this age group. Although efforts have been made to understand and reduce suicide in tribal communities, a large portion has focused on individual characteristics with less attention given to social factors that may also inform suicide. This article aims to build on a local conceptual model of NA youth suicide by examining additional potential social factors through qualitative interviews. Findings from the thematic analysis resulted in the identification of seven perceived social influences: contagion, violence and abuse, discrimination and bullying, negative expectations, spirituality, social support, and cultural strengths. Public health approaches to reduce suicide should consider local social factors that resonate with tribal communities to build resilience

Inibição da tripsina de bicho-mineiro do cafeeiro por um fator não-protéico presente em extratos de folhas de mamona Coffee leaf miner trypsin inhibition with castor bean leaf extracts mediated by a non-protein agent

Inibidores de tripsina representam uma estratégia de controle de insetos e, por isso, a identificação e caracterização desses inibidores são etapas muito importantes para que novas formas de controle de pragas sejam desenvolvidas. Os inibidores de tripsina atuam na digestão primária de proteínas e comprometem o processo digestivo por completo, reduzindo a disponibilidade de aminoácidos ao inseto. A incorporação de inibidores de tripsina na dieta de insetos-praga é uma forma de controle cuja eficácia foi verificada por diferentes autores. Este projeto foi conduzido a fim de se observar a eficiência de extratos de folhas de mamona na inibição "in vitro" de proteinases do tipo tripsina do bicho-mineiro do cafeeiro. Após testes realizados com os extratos de folhas de mamona não-fervidos e fervidos com e sem a adição de &#946;-mercaptoetanol 0,2% (v/v) e mediante precipitações com acetona, verificou-se que o inibidor é uma molécula termoresistente e não-protéica. Desta forma, iniciou-se um processo de purificação da molécula inibidora por meio de cromatografia de adsorção com posterior análise em espectrômetro de massas. Os resultados dos testes de inibição indicaram a presença de um inibidor de tripsina eficaz contra o bicho-mineiro do cafeeiro nos extratos de folhas de mamona capaz de inibir 2,48 + 0,15 UTI, o que representa aproximadamente 40% de inibição. Em testes realizados com tripsina bovina observou-se que o extrato de folhas de mamona não apresenta poder de inibição sobre essa enzima.<br>Trypsin inhibitors stand for a strategy of insect control and, therefore, the identification and characterization of these inhibitors are very important steps for new forms of pest control to be developed. Trypsin inhibitors act in the primary digestion of proteins and endanger the digestive process wholly, reducing the availability of aminoacids to the insect. The incorporation of trypsin inhibitors in the diet of pest insects is a control form whose efficacy was verified by different authors. In order to observe the efficiency of castor bean leaf extracts in inhibiting trypsin-like enzymes of the coffee leaf miner, an experiment was carried out with the purpose of observing an "in vitro" inhibition phenomenon. The results of the trypsin inhibition tests with normal and boiled with and without &#946;-mercaptoethanol 0.2% (v/v) castor bean leaf extracts and the results of the acetone precipitation process indicated that the inhibitor is a heat-resistant molecule and it is not a protein. This way, the purification process was made by adsorption chromatography with later analysis in mass spectrometer. The reached results indicated that the presence of a trypsin inhibitor of the coffee leaf miner in the castor bean leaf extracts is capable of inhibiting 2.48 + 0.15 UTI, which stands for about 40% of inhibition. Tests performed with bovine trypsin indicated that the castor bean leaf extract have no inhibiting power on this enzyme

Glycocapture-Assisted Global Quantitative Proteomics (gagQP) Reveals Multiorgan Responses in Serum Toxicoproteome

Blood is an ideal window for viewing our health and disease status. Because blood circulates throughout the entire body and carries secreted, shed, and excreted signature proteins from every organ and tissue type, it is thus possible to use the blood proteome to achieve a comprehensive assessment of multiple-organ physiology and pathology. To date, the blood proteome has been frequently examined for diseases of individual organs; studies on compound insults impacting multiple organs are, however, elusive. We believe that a characterization of peripheral blood for organ-specific proteins affords a powerful strategy to allow early detection, staging, and monitoring of diseases and their treatments at a whole-body level. In this paper we test this hypothesis by examining a mouse model of acetaminophen (APAP)-induced hepatic and extra-hepatic toxicity. We used a glycocapture-assisted global quantitative proteomics (gagQP) approach to study serum proteins and validated our results using Western blot. We discovered in mouse sera both hepatic and extra-hepatic organ-specific proteins. From our validation, it was determined that selected organ-specific proteins had changed their blood concentration during the course of toxicity development and recovery. Interestingly, the peak responding time of proteins specific to different organs varied in a time-course study. The collected molecular information shed light on a complex, dynamic, yet interweaving, multiorgan-enrolled APAP toxicity. The developed technique as well as the identified protein markers is translational to human studies. We hope our work can broaden the utility of blood proteomics in diagnosis and research of the whole-body response to pathogenic cues
