Conceptualising capabilities and value co-creation in a digital business ecosystem (DBE): a systematic literature review

Digital Business Ecosystem (DBE) is a topical concept for business organisations to collaborate in driving product or service innovation. DBE is supported by digital technologies which aim to create and co-create values among the participated business organisations. For achieving successful collaboration, business organisations need to understand their capabilities that lead to value creation. This approach is vital for a business organisation to benefit from the values co-created when collaborating with others. Failing to do so will cause inefficient collaboration. However, there is a lack of capability and value co-creation studies in the DBE context. Therefore, this paper aims to conceptualise capabilities and value co-creation through a systematic literature review. We analysed the findings by thematic analysis. The review results produced a set of research themes surrounding the capability and value co-creation concepts. The research themes contribute to informing future avenues in digital business ecosystem research

Insights into sugar metabolism during bilberry (Vaccinium myrtillus L.) fruit development

Bilberry fruit is regarded as one of the best natural sources of anthocyanins and iswidely explored for its health-beneficial compounds. Besides anthocyanins, one of themajor attributes that determine the berry quality is the accumulation of sugars thatprovide sweetness and flavor to ripening fruit. In this study, we have identified 25 sugarmetabolism-related genes in bilberry, including invertases (INVs), hexokinases (HKs),fructokinases (FKs), sucrose synthases (SSs), sucrose phosphate synthases (SPSs), andsucrose phosphate phosphatases (SPPs). The results indicate that isoforms of the identified genes are expressed differentially during berry development, suggesting special-ized functions. The highest sugar content was found in ripe berries, with fructose andglucose dominating accompanied by low sucrose amount. The related enzyme activi-ties during berry development and ripening were further analyzed to understand themolecular mechanism of sugar accumulation. The activity of INVs in the cell wall andvacuole increased toward ripe berries. Amylase activity involved in starch metabolismwas not detected in unripe berries but was found in ripe berries. Sucrose resynthesizing SS enzyme activity was detected upon early ripening and had the highestactivity in ripe berries. Interestingly, our transcriptome data showed that supplementalirradiation with red and blue light triggered upregulation of several sugar metabolism-related genes, including α- and β-amylases. Also, differential expression patterns inresponses to red and blue light were found across sucrose, galactose, and sugar-alcoholmetabolism. Our enzymological and transcriptional data provide new understanding ofthe bilberry fruit sugar metabolism having major effect on fruit quality (20) (PDF) Insights into sugar metabolism during bilberry ( Vaccinium myrtillus L.) fruit development

Pregnant Women’s Mental Health Status and its Related Factors Amidst COVID-19: A Cross- Sectional Study

Introduction: Since the emergence of COVID-19 pandemic, it has challenged the psychological aspect of everyone. Pregnant women being the vulnerable group are most likely to be at increased risk. This study aimed to assess the mental health status of the pregnant women residing in Nepal during COVID-19. Methods: A cross-sectional online study was carried out among 368 pregnant women during lockdown using Perceived stress scale-10, Generalized Anxiety Disorder-7 scale and Edinburg Perinatal Depression Scale. Data were analyzed using descriptive and inferential statistics. Results: The mean age of the participants was 27.06±4.64years. Getting infected with the virus (71.7%) was the major fear and inadequate antenatal checkup (61.1%) was the major effect experienced by the participants. The prevalence of stress, anxiety and depression was 41%, 28.5% and 33.2% respectively. Age, salary status of oneself and their husband, healthcare frontliner in the family and effect of social distancing were significantly associated with perceived stress. Age, education, employment, monthly income, trimester and effect of social distancing were significantly associated with anxiety. Salary status of husband, trimester, parity, being infected with COVID-19 and effect of social distancing were associated with depression. Conclusion: High prevalence of mental health disorders during COVID-19 outbreak suggests the importance of special attention on monitoring the maternal mental health status during such public health emergencies. Measures such as awareness program targeted to pregnant women and health education programs on how to cope during the pandemic situations should be made effective to rule down the mental health burden of COVID-19

Variability and path coefficient analysis for yield attributing traits of mungbean (Vigna radiata L.)

Seven mungbean genotypes were studied to estimate the genetic variability and path coefficient analysis for yield attributing traits at Agronomy farm of Institute of Agriculture and Animal Science (IAAS), Paklihawa Campus, Rupandehi, Nepal during summer season of 2017. The experiment was conducted with four replications in a randomized complete block design. Pant-5 and Maya were found high yielding genotypes. High genotypic coefficient of variation was exhibited by secondary branches and seed yield per plant. The low genotypic coefficient of variation was given by pod length, number of grains per pod and days to 50% flowering. High heritability was shown by test weight, secondary branches and seed yield per plant. Yield was correlated positively with days to flowering, pod length, primary branches per plant, test weight, biological, seed yield per plant and number of pods per plant. Biological yield, pod length, days to 50% flowering and no. of grains per pod contributed maximum positive and direct effect on yield indicating these three traits should be given emphasis while selecting high yielding mungbean cultivar for irrigated condition

Change in sugar levels and related gene expression during bilberry fruit development and ripening

Vaccinium myrtillus L., commonly known as European blueberry or bilberry, has been used as food and medicine since ancient times. Bilberries are highly valued in European and Asian markets. Sugar accumulation is responsible for the sweet taste of fruit, which is one of the main determinants of fruit quality. However, sugar metabolism in bilberry has not been studied before. This study was aimed to measure sugar content and to examine the expression of genes encoding the invertase enzymes; which are one of the key enzymes involved in the metabolism of sugars. All the analyses were done from four ripening stages of bilberry fruit (small unripe, large unripe, ripening, and fully ripe). Fructose was found to be predominant sugar in bilberry, followed by glucose. Sucrose was present in lower amount than fructose and glucose. The total sugar content was highest in fully ripe berries. Altogether 32 bilberry specific sugar metabolism genes were identified by bioinformatics tools, and expression of invertases, cell wall invertases (CwINVs), vacuolar invertases (VINVs), and neutral invertases (NINVs) were studied in detail. The different isoforms of invertases were differentially expressed, suggesting that they have specialized functions in the sugar metabolism pathway. VmCwINV2 and VmNINV5 were highly expressed in unripe berries while the levels of VmVINV1 and VmVINV2 transcripts were high in ripe berries. The findings of this study provide a basis for the further sugar metabolism research in bilberry fruit and deepen understanding of the role of sugar metabolism pathway to the fruit quality
