Essential for 21st Century Human Capital

This book explores the premise that coding is an essential 21st century skill required for all. Learning of coding does not merely mean learn the syntax, grammar and usage of a specific computer language like Python or Ruby, but the deeper concept of computational thinking. It is possible to learn aspects of computational thinking without learning coding, but coding is essential to acquire a sound understanding and knowledge of computational thinking. The book is intended to be helpful to policy makers at the Federal and Regional level who are concerned about the need for the Russian Education system to be responsive to the demands that will be faced by children growing up today into a networked, connected world of ever-increasing digitization and online and offline collaboration. The book will also be helpful to teachers and parents and other adults who are interested in understanding more about the subject of preparing children for the 21st century from both theoretical and practical perspectives. It is also useful to explain what this book is not, even though it refers to a substantive body of rich and growing academic work on the subject, it is not intended to be an academic work that would contribute new knowledge. Most of this academic work does not appear in headlines or social media feeds of non-specialists, but quite a bit of the work is very interesting and relevant. This book has tried to translate some of this knowledge in understandable terms to policy makers and practitioners, without oversimplifying complex realities. An extensive set of references including website urls will allow the interested reader to delve deeper into any of the topics

The Effect of Perceived Social Support Systems and Empowerment Approaches on the Quality of Life in Elderly Patients

Objective: This study investigated the effect of social support systems and strengthening approaches on the quality of life in elderly patients.Materials and Methods: This cross-sectional study was conducted with 390 participants above the age of 65 receiving service at the Kayseri State Hospital Geriatric Care Center between September-October 2019. The World Health Organization quality of life scale module and multidimensional scale of perceived social support and the patient perceptions of empowerment scale were used as the data collection tools. The effect of multidimensional scale of perceived social support and the patient perceptions of empowerment scale on the quality of life was tested using structural equation modeling.Results: It was determined that education, income, smoking, and chronic disease were significantly related to the quality of life of the elderly. When the effects of multidimensional scale of perceived social support on the quality of life were modeled, it was determined that social support and patient empowerment influenced the quality of life. In the model, patient empowerment significantly affected the quality of life with a standardized regression coefficient of 0.47 and a patient empowerment scale of 0.59.Conclusion: Patient empowerment level has a significant effect on the quality of life of the elderly, with social support. Patient empowerment is an essential determinant of the quality of life in the elderly

Irradiance and nutrient-dependent effects on photosynthetic electron transport in Arctic phytoplankton: A comparison of two chlorophyll fluorescence-based approaches to derive primary photochemistry.

We employed Fast Repetition Rate fluorometry for high-resolution mapping of marine phytoplankton photophysiology and primary photochemistry in the Lancaster Sound and Barrow Strait regions of the Canadian Arctic Archipelago in the summer of 2019. Continuous ship-board analysis of chlorophyll a variable fluorescence demonstrated relatively low photochemical efficiency over most of the cruise-track, with the exception of localized regions within Barrow Strait, where there was increased vertical mixing and proximity to land-based nutrient sources. Along the full transect, we observed strong non-photochemical quenching of chlorophyll fluorescence, with relaxation times longer than the 5-minute period used for dark acclimation. Such long-term quenching effects complicate continuous underway acquisition of fluorescence amplitude-based estimates of photosynthetic electron transport rates, which rely on dark acclimation of samples. As an alternative, we employed a new algorithm to derive electron transport rates based on analysis of fluorescence relaxation kinetics, which does not require dark acclimation. Direct comparison of kinetics- and amplitude-based electron transport rate measurements demonstrated that kinetic-based estimates were, on average, 2-fold higher than amplitude-based values. The magnitude of decoupling between the two electron transport rate estimates increased in association with photophysiological diagnostics of nutrient stress. Discrepancies between electron transport rate estimates likely resulted from the use of different photophysiological parameters to derive the kinetics- and amplitude-based algorithms, and choice of numerical model used to fit variable fluorescence curves and analyze fluorescence kinetics under actinic light. Our results highlight environmental and methodological influences on fluorescence-based photochemistry estimates, and prompt discussion of best-practices for future underway fluorescence-based efforts to monitor phytoplankton photosynthesis

Chlorophyll fluorescence-based estimates of photosynthetic electron transport in Arctic phytoplankton assemblages

AbstractWe employed Fast Repetition Rate fluorometry for high-resolution mapping of marine phytoplankton photophysiology and primary productivity in the Lancaster Sound and Barrow Strait regions of the Canadian Arctic Archipelago in the summer of 2019.
