Business Data Sharing through Data Marketplaces: A Systematic Literature Review

Data marketplaces are expected to play a crucial role in tomorrow’s data economy but hardly achieve commercial exploitation. Currently, there is no clear understanding of the knowledge gaps in data marketplace research, especially neglected research topics that may contribute to advancing data marketplaces towards commercialization. This study provides an overview of the state of the art of data marketplace research. We employ a Systematic Literature Review (SLR) approach and structure our analysis using the Service-TechnologyOrganization-Finance (STOF) model. We find that the extant data marketplace literature is primarily dominated by technical research, such as discussions about computational pricing and architecture. To move past the first stage of the platform’s lifecycle (i.e., platform design) to the second stage (i.e., platform adoption), we call for empirical research in non-technological areas, such as customer expected value and market segmentation.
Structure, Catalytic Mechanism, and Membrane Interaction of the mTOR Activator Rheb

The activator of mammalian target of rapamycin comp lex 1 (mTORC1), Ras homolog enriched in brain (Rheb), is a membrane-associated protein belonging to the Ras subfamily of small GTPases. Rheb’s slow GTPase activity is stimulated by the GTPase ac tiv ting protein (GAP) domain of tuberous sclerosis complex 1 and 2 (TSC1/2). Rheb hyperactivation, thr ough its overexpression or loss of TSC1/2 GAP function, results in hyperactivated mTORC1 signalin g culminating in tumourigenesis. The molecular details of Rheb GTP hydrolysis and the effect of me mbrane association on Rheb structure, dynamics and its GTPase function are currently not fully underst ood. The studies presented in this thesis focus on tw key determinants of Rheb function i) the mechanism of Rheb GTP hydrolysis and ii) the structural and functional consequence of Rheb-bilayer membrane int rac ion. Through studies of fluorescent nucleotides, we revealed that the conserved G2-box residue Tyr35 auto-inhibits GTP hydrolysis in Rheb. We demonstrated that a non-canonical catalyti c residue, Asp65, in the switch II region of Rheb, contributed more to the GTP hydrolysis rate than Gl 64, which corresponds to the canonical Ras Gln61. This non-canonical auto-inhibited mechanism of GTP hydrolysis was required for optimal mTORC1 regulation. These structural insights were then use d to guide the design of novel gainand loss-of function mutants by substitutions of the ultra-cons erved G3-box Gly63 of Rheb. Finally, using solution
Cypher Cab - A Blockchain enabled Transportation Application

Ridesharing is a transportation strategy that allows drivers to share their trips with other people which results in less travel expenses. It also minimizes traffic congestions and carbon emissions. Currently, most of the existing ride-sharing services rely on a central third party, like Uber, Ola, Didi which charges high service fees. In this paper, we are using blockchain technology to build a smart ride-sharing platform - CypherCab. All the services from registering as a driver, to using this platform for ridesharing will be written directly to the blockchain distributed ledger. Utilizing the decentralized nature of blockchain, the data stored in the blocks will be stored in a distributed ledger, hence removing the dependency on a central third-party server. Moreover, blockchain enables us to remove intermediaries and allows direct transactions between the driver and passengers. In this paper, we have implemented a prototype using smart contracts in the Ethereum network and Ganache test network.
Auditing the Governance and Management of Green IT

ABSTRACT Sustainability is not a trend; more and more areas of knowledge defend it and apply it among their main characteristics. The area of Information Technology (IT) has not been left behind and, through the so-called Green IT, advocates for a more sustainable environment. Organizations around the world are realizing that Green IT is an important asset that produces great benefits at ecological, social, and economic level. For this reason, we have developed a revised version of the “Governance and Management Framework for Green IT”. With this new version we intend to offer a more complete and solid guide that helps organizations to gradually implement, assess, and improve those characteristics of governance and management that are the basis of the processes and practices of Green IT. This proposal has been empirically validated through a case study and the results obtained demonstrate the validity, usefulness, and applicability of the framework for organizations.
Valoração ambiental da terra para o Estado do Paraná considerando o atributo reserva legal: uma abordagem hedônica com econometria espacial

A valoração ambiental busca estimar um valor econômico ao meio ambiente baseada em atributos ecosistémicos como a reserva legal. O objetivo deste estudo foi determinar o valor ambiental da terra considerando o efeito do atributo reserva legal nos municípios do Estado do Paraná, de acordo com a Norma Brasileira (NBR) 14.653. Utilizou-se o método dos preços hedônicos e a econometria espacial, com dados do Instituto Paranaense de Desenvolvimento Econômico e Social (IPARDES), Instituto Brasileiro de Geografia e Estatística (IBGE), e Secretaria de Estado da Agricultura e do Abastecimento (SEAB) do Paraná. Verificou-se a existência de autocorrelação global espacial positiva para alguns tipos de terra sobre áreas de reserva legal, assim como clusters Alto-Alto em municípios das microrregiões Oeste, Centro Ocidental e Norte Central. O modelo SLX mostrou os transbordamentos dos atributos e captou a relação positiva para o tipo de terra AIII, AIV e CVIII e a área de reserva legal dos municípios.
Evaluating Active Labor Markets in Romania

We evaluate the presence of effects from joining one of four active labour market programs in Romania in the late 1990s compared to the no-program state. Using rich follow-up survey data and propensity score matching, we find that three programs (training and retraining, self-employment assistance, and employment and relocation services) had success in improving participants' economic outcomes and were cost-beneficial from society's perspective. In contrast, public employment was found detrimental for the employment prospects of its participants.
Short Term Impacts of Harvesting Operations on Soil Chemical Properties in a Mediterranean Oak Ecosystem

Soil physical and chemical properties can be seriously affected by forest operations. There is a knowledge gap on this topic for oak ecosystems, which can play a significant role in the context of multiple-use forestry. The main objective of this study was to analyse forest floor and topsoil changes (0–10 cm) two years after the application of small-scale thinning (50% reduction of basal area) and clear-cut operations using mules to carry harvested material in a Northern Greece oak (Quercus frainet-to Ten) ecosystem. The total amount of forest floor (O 1 +O 2 horizons) was reduced by 37.8% in the thinned and 30.8% in the clear-cut plots compared to control plots. These large reductions are mainly due to reduction in the O 2 horizon in the treated plots. Decomposition was reduced in the treated plots, possibly due to the new drier conditions. Treatments increased the soil pH but not to a significant extent. No evidence of erosion was found in the experimental plots due to the protective function of the forest floor and the use of designated mule trails. The areal extent of soil compaction was limited to only 3% of the total area mainly due to the careful planning and implementation of animal skidding. Small differences in C (%) and Ν (%) were found among control, thinned and clear-cut plots. The limiting growth factors in Mediterranean oak ecosystems are soil depth and the seasonal change of soil moisture, especially during the summer dry period. More research on the definition of the optimum thinning degree and extraction systems in similar ecosystems will be important to satisfy the need to improve soil characteristics.
Diet and depressive disorders

ABSTRACT Background: The importance of foods or food constituents in mental health is increasingly recognized, and “nutritional psychiatry” is a growing discipline. Objective: This narrative review aims to present work supporting associations between food or food constituents and mental health, specifically depressive disorders. Methods: The data presented is derived from preclinical and clinical work, including in vitro and in vivo assays, as well as observational studies and randomized clinical trials of dietary interventions. The focus of the review is the mediation of inflammatory processes and oxidative stress by dietary constituents that are an integral part of a healthy diet, such as the Mediterranean diet and similar. Results and Discussion: We present evidence for the role of the diet in prevention and management of depressive disorders, beyond the effect of individual nutrients. The findings indicate that among the dietary components with higher degree of evidence to influence depressive disorders are long chain n-3 polyunsaturated fatty acids (EPA and DHA), and various dietary bioactive compounds, especially plant-derived secondary metabolites represented by polyphenols such as flavonoids and resveratrol. Conclusion: Diet exerts an important role on mental health, and evidence indicates that some dietary constituents contribute to the prevention of depressive disorders.
The Online Professor Today: From Isolation and Depression to Connected and Thriving

The online professor today is part of a high-risk group of workers experiencing adverse physical and mental symptoms that were unknown a decade ago. Depression, isolation, divorce, diabetes, antisocial behavior, PTSD, chronic pain, and even suicide is among crises happening now within this population segment once highly revered, yet few studies exist that determine how quickly the declination is occurring and if remedies from mainstream healthcare professionals are being offered; and if so, the degree of healing. Amelioration is often approached from an opposite perspective--meaning, change the behavior and the mindset change follows suit, as modeled by Alcoholics Anonymous, Weight Watchers, and Kaplan. New research, innovation, and application shows there is a surprising disconnect for achieving long-term and fulfilling change, in contrast to practiced methods in conventional healthcare. Subsequently, this research posits that change begins first with the mind, and after we better understand how identities and beliefs produce automated habits, behaviors once hazardous can be transformed into health and happiness.
Storming the Beachhead: An Examination of Developed and Emerging Market Multinational Strategic Location Decisions in the U.S.

Entering a foreign market is challenging given the fierce competition posed by local incumbents. The literature suggests that when entering a foreign market, it is advantageous to locate where there are agglomeration benefits. Given the dynamic nature of regional development, foreign firms have multiple location options. While the literature has primarily focused on developed country multinationals’ (DMNEs) location decisions, emerging market multinationals (EMNEs) are increasingly becoming influential in high-tech industries. Due to differences in DMNE and EMNE resource endowments, they may consider alternative options when locating abroad and, thus, we examine these nuances. Using multinomial logistic regression, we investigate domestic and foreign location patterns of firms within the U.S. biopharmaceutical industry as of 2018. We constructed a unique dataset of 19,962 U.S. locations and examined the location patterns of DMNEs and EMNEs from 61 countries and territories. Given the heterogeneity of regional development in the U.S., we developed a typology that stratifies regions into four categories (developed, growth, transitioning, and nascent). Counterintuitively, we find that foreign multinationals are more likely to be attracted to less developed regions than domestic firms and have different location patterns, not only compared to domestic firms, but also with respect to each other.
Turbulence Models For Computational Fluid Dynamics

Turbulent fluid flow is a very complicated natural phenomenon from the viewpoint of both understanding and analysis. Therefore, in turbulent motion studies, besides the theoretical analysis, statistical and empirical correlation methods must also be resorted to. The most fluid flows encountered in industry, especially in aeronautics, and civil, environmental, mechanical, and chemical engineering are turbulent and many phenomena, such as heat or mass transfer, are intimately linked to the fluid motion. In spite of the variety of experimental works on the structure of turbulent flows have so far been conducted, the fundamental mechanisms in turbulence phenomenon still remain incompletely clarified and many problems remain open.
A novel career development course for animal science students pursuing veterinary college admissions

Abstract A one-credit hour, elective, professional development course was created at North Carolina State University to introduce pre-veterinary track students to the admissions process and the breadth of the veterinary profession. The course was designed to facilitate career exploration while building self-efficacy through vicarious learning, interacting with speakers in various veterinary subfields, and addressing misperceptions about veterinary admissions. To evaluate the student learning objectives and improve upon the current practices of the course, data from two pretest and posttest course surveys for 235 course participants between Spring 2014 and 2017 were analyzed. The results of the study showed that students experienced significant gains in self-appraisal (Cohen’s d ranged 1.88 to 2.53), gathering occupational information (Cohen’s d ranged 1.59 to 2.53), goal selection (Cohen’s d ranged 2.14 to 2.53), and planning and problem-solving (Cohen’s d ranged 1.88 to 2.77) as well as experienced a decrease in five misperceptions about veterinary admissions. This novel course is presented as a prospective course for other universities.
Complex analysis of flax seeds composition for breeding programs

Single plant selection using complex of seed quality traits requires development and optimization of the methods, which allow qualitative and quantitative analysis applying minimum quantity of seeds. The proposed evaluation scheme of seed composition enables optimal use of seed material for individual plant analysis: oil percentage (Rushkovsky’s extraction method), fatty acid composition (vaporliquid chromatography), protein and ash content (dynamic thermogravimetry), elemental composition (electron probe X-ray fluorescence method). Reproducibility of analytical methods used was assessed by the coefficient of variation, the reproducibility index (ARI) and the convergence of data on seasonal cultivation.

In Silico Genome-Wide Identification and Characterization of Glutathione Peroxidase Gene Family in Wild Cherries (Prunus avium L)

Biotic and abiotic stresses are the main problems affecting the quantity and quality losses of antioxidants in wild cherry (Prunus avium L), which provide health benefits to humans, such as anti-allergic, anti-inflammatory, antimicrobial, and anti-cancer benefits. Glutathione peroxidase (GPX) isoenzymes act a major role in responding to oxidative stresses through the multiple metabolic pathways. Protein sequences of GPXs family form Arabidopsis thaliana and Oryza sativa were used to identify homologous proteins by the BlastP in the sweet cherry’s genome. After the alignment, the existence of the specific domain, phylogenetic relationships, subcellular localization analysis, as well as exon-intron structures and conserved motives were evaluated in this study. MicroRNA target site and codon usage bias were also investigated. Furthermore, the existence of cis-regulatory element and SSR markers were identified. The three-dimensional structure of the GPXs protein prediction and the accuracy of the predicted model was also investigated. Regarding molecular docking, the best pose for considering the accuracy of binding site was evaluated. Finally, by analyzing biological process and molecular function, gene ontology of the predicted protein was considered. We identified the five GPX genes in P. avium that classified into 3 separate groups based on their phylogenetic relationships. The predicted subcellular localization showed the GPX proteins that localized both chloroplast and mitochondria. Also, results showed ENC values were ranked 45.92 to 59.21 in PavGPX3 and PavGPX2. The results of cis‐regulatory elements showed PavGPX8 contained ten cis‐regulatory elements which was the lowest number among PavGPXs. The best pose and protein interaction in the verified 3D model were the first pose with the -28.5 minimization energy in docking process. It was concluded that the precise information on putative roles of P. avium GPXs genes could be helpful in determining their functional characterizations. The presence of several developmental process, stresses, light and hormones- responsive elements in the upstream of these genes, and GPXs‐targeted miRNAs suggested that GPX family members may play various roles in different biological responses. Finally, the GPXs gene was proposed as a good candidate for genetic engineering and breeding programs in order to introduce an abiotic stress- tolerant cultivar.
GCAP 2.0: A global 3-D chemical-transport model framework for past, present, and future climate scenarios

Abstract. This manuscript describes version 2.0 of the Global Change and Air Pollution (GCAP 2.0) model framework, a one-way offline coupling between version E2.1 of the NASA Goddard Institute for Space Studies (GISS) general circulation model (GCM) and the GEOS-Chem global 3-D chemical-transport model (CTM). Meteorology for driving GEOS-Chem has been archived from the E2.1 contributions to Phase 6 of the Coupled Model Intercomparison Project (CMIP6) for the preindustrial and recent past. In addition, meteorology is available for the near future and end-of-the century for seven future scenarios ranging from extreme mitigation to extreme warming. Emissions and boundary conditions have been prepared for input to GEOS-Chem that are consistent with the CMIP6 experimental design. The model meteorology, emissions, transport and chemistry are evaluated in the recent past and found to be largely consistent with GEOS-Chem driven by the Modern-Era Retrospective analysis for Research and Applications Version 2 (MERRA-2) product and with observational constraints.
Design and Preliminary Testing of a Magnetic Spring as an Energy-Storing System for Reduced Power Consumption of a Humanoid Arm

The increasing use of robots in the industry, the growing energy prices, and higher environmental awareness have driven research to find new solutions for reducing energy consumption. In additional, in most robotic tasks, energy is used to overcome the forces of gravity, but in a few industrial applications, the force of gravity is used as a source of energy. For this reason, the use of magnetic springs with actuators may reduce the energy consumption of robots performing trajectories due their high-hardness magnetic properties of energy storage. Accordingly, this paper proposes a magnetic spring configuration as an energy-storing system for a two DoF humanoid arm. Thus, an integration of the magnetic spring system in the robot is described. A control strategy is proposed to enable autonomous use. In this paper, the proposed device is modeled and analyzed with simulations as: mechanical energy consumption and kinetic energy rotational and multibody dynamics. Furthermore, a prototype was manufactured and validated experimentally. A preliminary test to check the interaction between the magnetic spring system with the mechanism and the trajectory performance was carried out. Finally, an energy consumption comparison with and without the magnetic spring is also presented.
Salient Midlatitude Ionosphere‐Thermosphere Disturbances Associated With SAPS During a Minor but Geo‐Effective Storm at Deep Solar Minimum

This work conducts a focused study of subauroral ion‐neutral coupling processes and midlatitude ionospheric/thermospheric responses in North America during a minor but quite geo‐effective storm on September 27–28, 2019 under deep solar minimum conditions. Several prominent storm‐time disturbances and associated electrodynamics/dynamics were identified and comprehensively analyzed using Millstone Hill and Poker Flat incoherent scatter radar measurements, Fabry‐Perot interferometer data, total electron content data from Global Navigation Satellite System observations, and thermospheric composition O/N2 data from the Global‐scale Observations of Limb and Disk mission. Despite solar minimum conditions, this minor storm produced several prominent dynamic features, in particular (a) Intense subauroral polarization stream (SAPS) of 1,000 m/s, overlapping with a deepened main trough structure. (b) An enhanced westward wind of 230 m/s and a significant poleward wind surge of 85 m/s occurred in the post‐SAPS period. (c) Large‐scale traveling ionospheric disturbances (TIDs) were generated and propagated equatorward across mid‐latitudes in the storm main phase. TID characteristics were significantly affected by SAPS, evolving into divergent propagation patterns. (d) SAPS was situated on the poleward edge of a considerable storm‐enhanced density structure. (e) The midlatitude ionosphere and thermosphere exhibited a prolonged positive storm effect in the main phase and beginning of recovery phase, with 5–10 TECU increase and 10%–30% O/N2 enhancement for 12 h. This was followed by a considerable negative storm effect with 5–10 TECU and 20%–40% O/N2 decrease. Results show that minor storm intervals can produce substantial mid‐latitude ionospheric and thermospheric dynamics in low solar flux conditions.
