Digital Entrepreneurship and its Role in Innovation Systems: A Systematic Literature Review as a Basis for Future Research Avenues for Sustainable Transitions

Digital entrepreneurship is an essential driver within the innovation system. It changes the structure, aims, and networking mechanisms of the overall business system and, ultimately, affects the various levels and dimensions of the innovation system. Bringing inevitable changes to the innovation system, digital technologies may not only provide new business opportunities but also be disruptive and cause new vulnerabilities. In order to gain a rigorous understanding of the hybrid concept of digital entrepreneurship and its role within the transformation of the innovation system, we conducted a systematic literature review. The results of 52 core papers allow for the identification of key categories of digital entrepreneurship and also its differentiation from other types of business activities. The analysis leads to the distinction of the determinants of digital entrepreneurship within three core dimensions of the innovation system, which encompass the entrepreneur (including, e.g., behavioral, competence. and mentality patterns, as well as personal outcomes and consequences of entrepreneurial activity), the entrepreneurial process (including activities that concern digitalization in organizational management processes, transformations within strategic and operational activities, and digital start-up establishment), and its relevant ecosystem (which encompasses, among others, the influence that external infrastructure and institutions have on digital entrepreneurship development). The systematization of the existing literature is highly relevant for future research that aims to understand the interrelations between the transformation of entrepreneurial structures within innovation systems as well as the socioeconomic system in general. Such understanding requires further extended research in fields related to method, content, and theory.
Evaluating the Relationship between Parental Dental Anxiety and Early Childhood Caries

Background Early Childhood Caries (ECC) is considered as the most prevalent childhood disease. Numerous factors have been mentioned for the formation of ECC. This study evaluated the relationship of parental dental anxiety and ECC in Iranian Children. Materials and Methods In this cross-sectional study, 340 parent-child dyads were divided into two groups: the first group consisted of 170 parents and their 3-6-year-old child with ECC (the case group), and the second group consisted of 170 parents and their 3-6-year-old child without ECC (the control group). Samples were selected using cluster random sampling from the kindergartens of Zahedan,Iran in 2019. A questionnaire containing parent’s information (age, education level, occupation and monthly income), and Corah Dental Anxiety Scale (CDAS) were used in this study. Data were analyzed using SPSS software version 20. Results The anxiety level of mothers and fathers of the case group was similar to the control group (P= 0.284 and P= 0.114, respectively). There was no statistically significant difference between the level of parental anxiety (mother and father), and dmft index in the case group (P= 0.154 and P= 0.255, respectively). Also, mothers who were equal or less than 30 years-old were more anxious than mothers with more than 30 years-old (P= 0.034). Conclusion Based on the results, there were no significant differences in the groups based on parental dental anxiety. In other words, parental dental anxiety cannot lead to ECC in children.
Tailoring the solar-blind photoresponse characteristics of β-Ga2O3 epitaxial films through lattice mismatch and crystal orientation

Realizing manipulation of the photoelectric properties of wide bandgap semiconductors is a main challenge for successful next-generation functional optoelectronics. As an intriguing wide bandgap semiconductor, β-Ga2O3 (e.g. ∼4.9 eV) is emerging as a promising candidate for photodetectors operating in the solar-blind region. Here, we show that by selecting substrates with different symmetries and lattice parameters (i.e. (100) MgO, (100) MgAl2O4 and (0001) α-Al2O3), epitaxial β-Ga2O3 films with (100)-or 2ˉ01-orientation could be fabricated. We found that the photoresponse characteristics are strongly correlated with the lattice mismatch and film orientation. In particular, (100)-oriented β-Ga2O3 film grown on MgO substrate with smaller lattice mismatch exhibited a 254 nm responsivity of 0.1 A · W−1 and detectivity of 4.3 × 1012 Jones, which are approximately an order of magnitude higher than that of the 2ˉ01-oriented β-Ga2O3 film. Our work may provide a strategy to develop further high performance solar-blind photodetectors.

The design of the study is a descriptive research survey, and the study population comprises of all the Economics senior secondary II students in Edo South Senatorial District of Edo State, Nigeria. The sample size of this study consists of 390 Economics senior secondary school class II. The instrument used for this study is a questionnaire, which was validated by expert in Measurement and Evaluation as well as Educational Psychology. The Cronbach Alpha reliability was used to determine the consistency of the instrument which was at 0.84. The data collected was analyzed using Pearson’s product-moment correlation to determine the relationship between metacognitive skills, self-assessment, and Economics student’s achievement. The two hypotheses were tested at 0.05 level of significance. Firstly, the data analysis showed that there is a relationship between metacognitive skills and Economics students’ achievement. Secondly, it also shows that self-assessment is related to the achievement of Economics students. From the findings, it was recommended that Economics teachers should give Economics students more homework that will compel the students to search for information online (e-learning). Secondly, Economics teachers should consistently monitor, check when relevant, and reply the Economics students based on the assignment given to them. Finally, a significant relationship exists between students’ metacognitive skills and determinant of academic performance.
Factors Affecting the Popularity of Video Content on Live-Streaming Services: Focusing on V Live, the South Korean Live-Streaming Service

Naver V Live, a South Korean live-streaming service, showcases video contents specific to the entertainment industry, such as K-pop and music. On V Live, K-pop stars and their fans can interact directly in a natural way, and V Live provides high-quality video content with novel topics. This study has identified key characteristics of video content that affect its popularity. A total of 620 video contents of five leading Star channels were classified on the basis of production company, type of video content, and whether it was live-streamed or not. The popularity of video content was measured by the number of comments, hearts, and views. To control potential bias, additional variables were set as control variables—such as the number of channel subscribers, mini-album sales, if the video content was previewed, and cumulative number of days since the video content was uploaded. For analysis, a hierarchical linear regression was conducted. The findings suggest future directions in video content planning.
Research and Application of Biochar in Soil CO2 Emission, Fertility, and Microorganisms: A Sustainable Solution to Solve China’s Agricultural Straw Burning Problem

This study aimed to explore a new way to address the burning of agricultural waste in China while achieving the sustainable use of it. Three agricultural wastes (Wheat straw, peanut shell, and rice husk) were slowly pyrolyzed into biochar, which was subsequently added to the soil to reduce CO2 emissions from the soil, and to improve soil fertility as well as microbial community structure. The biochar and raw materials were added to the soil and cultured under controlled conditions, and then the CO2 emissions produced from the mixing. At the same time, this study used pot experiments to determine the effects of biochar on tobacco soil physical and chemical properties and, therefore, the microbial communities of the soil. This study suggests that (1) biochar can effectively reduce soil CO2 emission rate. Compared with the control, peanut shell biochar could reduce the total CO2 emissions of soil by 33.41%, and the total CO2 emissions of wheat straw biochar treatment was 90.25% lower than that of wheat straw treatment. (2) The soil’s physical and chemical properties were improved. The soil bulk density of wheat straw biochar treatment kept 34.57% lower than that of the control as well as 21.15% lower than that of wheat straw treatment. The soil’s organic carbon of peanut shell biochar treatment was 87.62% more than that of peanut shell treatment. (3) Biochar changed soil microbial community structure. (4) Biochar is suitable for tobacco growth. Peanut husk biochar significantly increased the total biomass of tobacco, and wheat straw biochar significantly increased tobacco root vigor. This study concluded that processing Chinese agricultural waste into biochar and adding it to the soil instead of burning it directly would be an effective means to reduce greenhouse gas emissions, to improve soil, and to promote crop growth.
Experimental and numerical investigations of actuator disks for wind turbines

The expenses of a wind turbine modeling in particular a wind farm modeling either numerically or experimentally cause to take the advantages of actuator disks (AD). Porous disks (PD) are used to simulate actuator disks in experiments especially for wake studies. A rotor of a wind turbine replaced by a PD can be modeled efficiently with less cost and process time. For a proper PD selection, some semi‐empirical equations are suggested for a range of solidity of 0.2‐0.6. These equations came from a number of tests. The PDs with different dimensions and solidity values were considered for the tests and models. The results of 2D and 3D numerical simulations and the experimental results show that at the solidity of 0.5, the coefficient of performance of a PD reaches approximately 16/27 which is equal to the Betz's limit; the relation between the coefficient of power and the solidity is fitted by a parabolic equation. The average error of the proposed equations for the power coefficient is reported 1.59%. Finally, based on the current results, some semi‐empirical equations are suggested to help the initial PD selection, and then, the cost of further studies may decrease.

Surgical management of fracture shaft tibia with closed interlocking intramedullary nailing – A clinical study

Introduction: The tibia being the most commonly fractured long bone. A study was conducted to analyze the efficacy of closed intramedullary nailing tibial shaft fractures. Materials and methods: Study was conducted in the Department of orthopedics. Individuals with closed tibial diaphyseal fractures of >18 years, open diaphyseal fractures of tibia type I, type II were included. Open diaphyseal fractures of tibia Type III A, B, C, tibial fractures with intraarticular extensions and medically ill were excluded. Under spinal anesthesia, intramedullary locking was done as per the protocol. Results: During the study period, 50 fractures were included. the male-female ratio was 5.25. The youngest patient was 19 years and the oldest patient was 67 years. 60% of the participants had right tibial fractures and 40% with left. Thirty-nine (78%) participants simple and 22% (11) had type I and type 11 compound fractures. The majority of fractures (58%; 29) were united within 18-20 weeks. The average healing time was 19 weeks. Conclusion: In this study 16.9 weeks was the average healing time and 76% patients showed excellent outcome.
Psychometric Properties, Measurement Invariance, and Construct Validity of the Italian Version of the Brand Hate Short Scale (BHS)

Brand hate can be defined as the consumer’s dissatisfaction with the product or service performance. The consumer’s hatred of the brand is related to the desire for revenge and avoidance. This kind of emotion does not remain only a desire; it is often transformed into real actions that lead to consumer behavior. Although the analysis of the literature provides useful insights and interesting suggestions about the phenomenon of brand hate, to date, very few studies and scales that are capable of measuring this phenomenon have been developed, especially in the Italian context. The present work investigated the psychometric properties of an Italian adaptation of the BHSs (N = 422) with the aim of verifying the same factor structure found in the original German version. Results confirmed a one-factor structure (first order, 6 items). Moreover, the scale was found to be invariant across gender. This suggests that companies must first have adequate systems and mechanisms in place to understand the reasons that drive consumers to hate the brand and implement recovery strategies to address this hatred. The achievement of sustainability or failure to do so can add to or detract from a brand’s value in the marketplace.
Novel Phosducin-Like Protein Binding Partners: Exploring Chaperone and Tumor Suppressor Protein Interactions

Novel Phosducin-Like Protein Binding Partners: Exploring Chaperone and Tumor Suppressor Protein Interactions Amy J. Gray Department of Chemistry and Biochemistry, BYU Doctor of Philosophy Many proteins cannot fold into their native state without the assistance of one or more molecular chaperones. Chaperonins are an essential class of chaperones that provide an isolated chamber for proteins to fold. CCT, a group II chaperonin found in eukaryotes assists in the folding of actins, tubulins, and many other cellular proteins. PhLP1 is a member of the phosducin protein family that assists CCT in the folding of Gβ and its subsequent assembly with Gγ. However, previous studies have not addressed the scope of PhLP1 and CCT-mediated Gβγ assembly. The data presented in Chapter 2 shows that PhLP1 plays a vital role in the assembly of all Gγ subunits that form dimers with Gβ2 and the assembly of Gγ2 with Gβ1-4, without affecting the specificity of the Gβγ interactions. These findings suggest that PhLP1 has a general role for the assembly of all Gβγ combinations. Although the role of PhLP1 as a co-chaperone for Gβγ assembly has been established, other possible functions for PhLP1 either as a co-chaperone or otherwise are yet to be investigated. A known tumor suppressor protein, PDCD5, was found to interact with PhLP1 in a co-immunoprecipitation proteomics screen. The data presented in Chapter 3 show that PDCD5 binds PhLP1 indirectly through a ternary complex with CCT. Our results signify that the apoptotic function of PDCD5 is cytosolic, is phosphorylation dependent, and most likely involves CCT. Moreover, structural analysis suggests that over-expressed PDCD5 blocks βactin from entering the CCT folding cavity, suggesting a co-chaperone role for PDCD5 in inhibiting or enhancing folding of yet-to-be determined CCT substrates. Compared to PhLP1, the functions of other members of the phosducin family, PhLP2A, PhLP2B, and PhLP3, are poorly understood. They have no role in G-protein signaling, but appear to assist CCT in the folding of actin, tubulin and proteins involved in cell cycle progression. Chapter 4 investigates the possibility of PhLP2 and/or PhLP3 acting as cochaperones in the folding and assembly of actins and tubulins. In addition, another mediator of cellular signaling, 14-3-3ε, was found to interact with PhLP2A in a phosphorylation dependent manner and relieve the inhibition of β-actin folding caused by PhLP2A over-expression.
Effect of Chelated Mineral Mixture on Blood Profile and Fertility in Anoestrus Buffaloes of Tribal Areas of Dahod District in Gujarat, India

An on-farm trial for 90 days was conducted at four tribal villages to assess the effect of chelated mineral mixture (CMM) supplementation on blood biochemistry as well as hormonal and mineral status, nutrient intake and reproductive performance of the anoestrus buffaloes (n=24). The animals selected were randomly divided into two groups of 12 animals each. The group T1 was the control group (farmer’s feeding schedule), and T2 treatment group (T1 + CMM @ 50 g/animal/day). Blood collection was done on days 0, 45, and 90 of the experiment from the animals of both the groups for assessment of blood biochemical, hormonal, and mineral status of the animals. Average DM, DCP, and TDN intake in anoestrus buffaloes calculated as per information collected from farmers were statistically similar among both the groups and were as per ICAR requirements of animals. Results revealed significant p less then 0.05 improvement in hemoglobin, serum glucose, total protein, total cholesterol, progesterone, estradiol and macro (Ca, P) – micro (Zn, Fe, Cu, Co, Mn) mineral status of chelated mineral supplemented group as compared to control animals. The number of days taken to come into oestrus in anoestrus buffaloes (51.22±3.78 vs 75.00±6.18 days for 9 vs 5 animals), as well as the cost of feeding (Rs. 5441 vs 8039), was also significantly p less then 0.05) reduced upon supplementation of CMM as compared to control group. The control group recorded a 32.32% higher cost of rearing than the treatment group during the experimental period. The findings revealed the beneficial role of chelated minerals supplementation in improving the health, nutritional and reproductive status of anoestrus buffaloes.
Spatiotemporal Variability of Precipitation in Beijing, China during the Wet Seasons

To comprehensively evaluate the changes in precipitation patterns in the context of global climate change and urbanization, the spatiotemporal variability of precipitation during the wet seasons of 1981–2017 in Beijing was analyzed in this study using up-to-date daily and hourly precipitation data from observation stations. It was concluded that the average annual precipitation in wet seasons showed a downward trend, while the simple daily intensity index (SDII) showed an upward trend. Precipitation in the central urban area of Beijing showed obvious changes from 1981 to 2017; the average annual precipitation in the central urban area was almost as great as that in Miyun country after 2010, which was the storm center for the past three decades. The average annual maximum 3-h and 6-h precipitation in the 2010s was higher than the past three decades, especially in urban and suburban areas. In addition, the atmospheric circulation index, urbanization impact, and topography were all found to be important factors that affect the pattern of precipitation in Beijing.
Satisfaction and perceptions of research participants in clinical and translational studies: An urban multi-institution with CTSA

Abstract Purpose: To examine research participants’ levels of satisfaction and perceptions and aid researchers to better engage research volunteers from all racial and ethnic populations in clinical trials. A participant satisfaction survey was developed that focused on three domains to reflect satisfaction with delivery of care, environment, and center operations. In addition, the survey contained open-ended questions to reflect overall experiences and perceptions. Two hundred and seventy-eight participants (55% African American and 29% non-Hispanic Whites) with an average age of 52 years completed the survey. Results: The results indicated that the majority of the participants rated their satisfaction very highly across all domains. Ninety percent stated they were very satisfied/satisfied or very strongly agreed/agreed in the three domains. Obtaining high-quality care/access to health care professionals (60%), learning more about their illness/disease (60%), and helping others (57%) were noted as important factors in choosing to participate in a trial. Regarding overall experience, majority of respondents stated that friendliness, expertise of staff, learning more about their disease, and contributing to science were important. Further, financial compensation was not a primary motivation for participation. A majority of participants stated that they would participate in future studies and would recommend a friend or a family member to participate in clinical trials. Conclusions: The findings indicate that the degree of satisfaction with the research staff and with the specific trial itself are important determinants for enrolling, completing a study, and for participating in future trials.
