Effects of Positive Emotions on Enhanced IT Use

Recently emotions started to receive more attention from IT use researchers. However, similarly to psychology, much of the focus goes to investigation of negative emotion influence. Drawing on broaden-and-build theory and flow theory, this manuscript aims to explore how positive emotions can influence enhanced IT use. In order to test it, experiment study is proposed. Findings are expected to support influence of positive emotions on enhanced IT use via state of flow. This suggests that organizations seeking to improve individual IT use should aim to stimulate positive emotions in individual users

Exploring Critical Success Factors in Agile Analytics Projects

Via updating Chow and Cao’s list of success factors for agile projects, attributes of potential critical success factors (CSF’s) for agile analytics projects were identified from the literature. Ten new attributes were added to Chow and Cao’s original list. Seven new attributes from the general agile project literature address: risk appetite, team diversity and availability, engagement, project planning, shared goals, and methods uncertainty. Three attributes specific to analytics projects were added: data quality, model validation, and building customers’ trust in model solution. The potential validity of the various CSF’s and attributes was explored via data from case studies of two analytics projects that varied in deployment success. The more successful project was found to be stronger in almost all the factors than the failed project. The findings can help researchers and analytics practitioners understand the environmental conditions and project actions that can help get business value from their analytics initiatives

Small Open Reading Frames, Non-Coding RNAs and Repetitive Elements in Bradyrhizobium japonicum USDA 110

Small open reading frames (sORFs) and genes for non-coding RNAs are poorly investigated components of most genomes. Our analysis of 1391 ORFs recently annotated in the soybean symbiont Bradyrhizobium japonicum USDA 110 revealed that 78% of them contain less than 80 codons. Twenty-one of these sORFs are conserved in or outside Alphaproteobacteria and most of them are similar to genes found in transposable elements, in line with their broad distribution. Stabilizing selection was demonstrated for sORFs with proteomic evidence and bll1319_ISGA which is conserved at the nucleotide level in 16 alphaproteobacterial species, 79 species from other taxa and 49 other Proteobacteria. Further we used Northern blot hybridization to validate ten small RNAs (BjsR1 to BjsR10) belonging to new RNA families. We found that BjsR1 and BjsR3 have homologs outside the genus Bradyrhizobium, and BjsR5, BjsR6, BjsR7, and BjsR10 have up to four imperfect copies in Bradyrhizobium genomes. BjsR8, BjsR9, and BjsR10 are present exclusively in nodules, while the other sRNAs are also expressed in liquid cultures. We also found that the level of BjsR4 decreases after exposure to tellurite and iron, and this down-regulation contributes to survival under high iron conditions. Analysis of additional small RNAs overlapping with 3’-UTRs revealed two new repetitive elements named Br-REP1 and Br-REP2. These REP elements may play roles in the genomic plasticity and gene regulation and could be useful for strain identification by PCR-fingerprinting. Furthermore, we studied two potential toxin genes in the symbiotic island and confirmed toxicity of the yhaV homolog bll1687 but not of the newly annotated higB homolog blr0229_ISGA in E. coli. Finally, we revealed transcription interference resulting in an antisense RNA complementary to blr1853, a gene induced in symbiosis. The presented results expand our knowledge on sORFs, non-coding RNAs and repetitive elements in B. japonicum and related bacteria

Antecedents of Project Agility in Analytics Projects

Agile project management methods have been widely adopted since the publication of the Agile manifesto. However, the nature of project agility needs further theoretical development and empirical support. Consequently, this study defines project agility and then explores the factors that influence project teams’ achievement of agility. Complex Adaptive Systems (CAS) theory is adopted as a theoretical lens suitable to address the emerging, co-evolving nature of projects. A case-based research methodology is used to examine several analytics projects. Overall, the proposed study is designed to contribute to the project agility literature by applying CAS theory in the context of business analytics

Project Team Agile Capacity

Agile project management methodologies have been widely adopted since the 1990s. However, there is a lack of empirical investigations and theoretical development. Drawing on capacity theory, this manuscript explores components of agile capacity and its influence on project performance. An online survey study is proposed. Findings are expected to develop an instrument that measures agile capacity and test the influence of agile capacity on project performance. The results can then be used to evaluate and adjust the agile capacity of a project

Role of reputation cues in trust formation for a developer\u27s decision to join Open Source Software projects

Level of contributors\u27 activity around an Open Source Software (OSS) project is one of the key factors in terms of its survival and success. There are several factors that affect a developer\u27s decision to join an OSS project, yet little research examined the influence of third-party assessments on a developer\u27s intention to join a project. Drawing on signaling theory, this manuscript explores how third-party assessment can influence a developers\u27 decision to join an OSS project. In order to test it, vignette survey study was conducted manipulating reputation, development experience, and a number of current OSS projects of existing developers in the OSS project. The findings suggest that all three signals have a positive influence on developer\u27s decision to join the OSS project. This suggests that projects seeking to expand the number of contributing developers should consider offering information about its star developers

Currant growing technology and mechanized harvesting-review

Currant is a technological, fast-growing, high-yielding crop with a high content of vitamins in the fruit. The intensification of production provides for an increase in the productivity of plantings and a reduction in the cost of production due to the introduction of new cultivation technologies. The main production expenses are connected with harvest. The authors of this paper present the first and modern berry harvesters that reduce the cost of production and ensure high productivity of automated labor. The prospect of using technologies is based on agricultural techniques for cultivating highly productive, disease-and pest-resistant currant cultivars with a certain bush habit and physical and mechanical parameters of berries. Scientists have developed new breeding programs for Ribes, taking into account the genetic characteristics of the cultivar. The review presents the main cultivars of currants grown commercially in Europe, the USA, and Russia. Information about crop cultivation technologies is summarized and analyzed

Agrometeorological and Morpho-Physiological Studies of the Response of Red Currant to Abiotic Stresses

The aim of this work was to study the mechanism of climatic adaptation of red currant genotypes (Ribes rubrum L.) on the basis of physiological, biochemical and agrometeorological measurements and to determine the different phenophases of plant development identify adaptive genotypes for introduction. The studies were carried out in 2014–2017. The indicators of the water status of annual shoots (water content, water retention capacity), the biochemical composition of berries (vitamin C) and phenological observations were evaluated, taking into account meteorological data. The genotypes of R. petraeum Wulf. and R. multiflorum Kit. had the longest production period. Ambiguous data on the influence of temperature on the content of ascorbic acid in berries were revealed. High temperatures (>+26 °C) contributed to a greater accumulation of ascorbic acid in the cultivars of R. vulgare Lam. High accumulations of vitamin C in the range of +25–27 °C were found in R. petraeum Wulf. and R. multiflorum Kit.. High water content and water loss contributed to early recovery from the dormant state and reduced resistance to spring temperature changes in R. vulgare Lam. Genotypes of R. vulgare Lam., and R. multiflorum Kit. are promising for growing in a zone with a temperate continental climate. The genotypes of the species R. petraeum Wulf are suitable for introduction to the areas with a continental climate. The obtained results are important for adaptive gardening

New methods in genotype diagnostics of small-fruit crops for intensive gardening

Physiological and morphological studies of red Russian and foreign breeding red currant varieties were carried out for establishing intensive plantings and introduction. Varieties Dana, Niva, Vika, Hollandische Rote are yielding, highly resistant and promising for introduction and industrial cultivation, during dry periods they are able to regulate metabolism through changing indicators of water balance (water deficit, fractional composition of water) and photosynthetic apparatus of leaves (leaf lamina area). Using Natali, Shchedraya and Jonkheer Van Tets varieties in production is possible with application of artificial irrigation. Selyanochka variety is most affected by weather conditions and is recommended to be grown in temperate climate area. Physiological and morphological methods of research allow to diagnose the genotypes resistance of garden crops to growing period abiotic factors at the early stages of plant development, they are confirmed by field observations and are promising in diagnosis for establishing intensive gardens and berry-fields
