Orbitals in General Chemistry, Part II: Mathematical Realities

In Part II of a three-part series, we discuss two factors absent from textbooks of general chemistry that are important in a discussion of teaching orbitals. First, atomic orbitals are shown systematically to comprise algebraic formulae in coordinates of not one but four sets (spherical polar, paraboloidal, ellipsoidal, spheroconical coordinates). Each formula has its corresponding shape as a surface of constant amplitude; some visual examples are provided. Second, the argument that molecular structure is incompatible with quantum mechanics is presented. Despite the utility of orbitals as mathematical functions in various calculations, they are intrinsically complicated for the traditional purpose of qualitative explanation of molecular structure.

Orbitals in General Chemistry, Part I: The Great Debate

In Part I of a three-part series, we present an objective survey of the technical literature discussing the inclusion of orbitals in high-school and post-secondary general chemistry. We start with the definition of orbitals. The presentation of orbitals in secondary (high) school is presented with arguments for and against. The content of orbitals in the curriculum of general chemistry is presented and summarized in terms of 1) electron configuration, 2) periodic table, 3) molecular structure and 4) reactivity. Previous discussion in favor of and against each theme is presented. Recent research in chemical education is also reviewed.

ARTIFICIAL INTELLIGENCE IN ECONOMY AND POLICY NOWADAYS. ARTICLE 3. ARTIFICIAL INTELLIGENCE IN RUSSIAN AND FOREIGN PUBLIC POLICY

The third and final article of the three-part series of articles «Artificial intelligence in the economy and politics of our time» (the first and second articles of the series were published in the fourth and fifth issues of the journal for this year, respectively) presents the results of a study of the goals, motivations and specifics of the adoption of national strategies to support the development of artificial intelligence in different countries. It is shown that such a strategy in Russia is based on the idea of the most important role of using artificial intelligence in solving the most complex economic, social, and military-political problems of the country. Differences in conceptual approaches to the development of research and practical use of artificial intelligence developments in the national strategies of the largest countries of the world — the United States, China and India.

Power, control, communities and health inequalities. Part II: measuring shifts in power.

In the health field, there is great interest in the role empowerment might play in reducing social inequalities in health. Empowerment is understood here as the processes of developing capabilities that individuals and/or communities need to exercise control over decisions and actions impacting on their lives and health. There is a fundamental problem, however, in identifying and measuring capabilities for collective control that emerge at the level of the collective, with much of the existing literature focusing on individual measures even where community-level processes are concerned. Collective measures need to capture the dynamics of interactions within and between groups, not simply aggregate individual-level measures. This article, Part 2 in a three-part series, takes up the challenge of identifying qualitative markers of capabilities for collective control. We applied the emancipatory power framework (EPF) reported in Part 1 of the series, to qualitative data generated during a longitudinal evaluation of a major English area-based empowerment initiative, the Big Local (BL). We identified empirical 'markers' of shifts towards greater collective control pertaining to each of the 'power' dimensions in the EPF-'power within', 'power with' and 'power to'-and markers of communities exercising 'power over' other institutions/community members. These markers can usefully be applied in the evaluation planning and evaluation of empowerment initiatives. Part 3 in the series uses these markers and a second analytical framework developed during our evaluation of BL to explore how power dynamics unfold in participatory spaces in BL neighbourhoods.

Power, control, communities and health inequalities I: theories, concepts and analytical frameworks.

SummaryThis is Part I of a three-part series on community empowerment as a route to greater health equity. We argue that community ‘empowerment’ approaches in the health field are increasingly restricted to an inward gaze on community psycho-social capacities and proximal neighbourhood conditions, neglecting the outward gaze on political and social transformation for greater equity embedded in foundational statements on health promotion. We suggest there are three imperatives if these approaches are to contribute to increased equity. First, to understand pathways from empowerment to health equity and drivers of the depoliticisation of contemporary empowerment practices. Second, to return to the original concept of empowerment processes that support communities of place/interest to develop capabilities needed to exercise collective control over decisions and actions in the pursuit of social justice. Third, to understand, and engage with, power dynamics in community settings. Based on our longitudinal evaluation of a major English community empowerment initiative and research on neighbourhood resilience, we propose two complementary frameworks to support these shifts. The Emancipatory Power Framework presents collective control capabilities as forms of positive power. The Limiting Power Framework elaborates negative forms of power that restrict the development and exercise of a community’s capabilities for collective control. Parts II and III of this series present empirical findings on the operationalization of these frameworks. Part II focuses on qualitative markers of shifts in emancipatory power in BL communities and Part III explores how power dynamics unfolded in these neighbourhoods.

Unblocking Scholarly Writing–Part II: Minimizing Procrastination and Maximizing Mindset to Accomplish Publishing

Abstract Procrastination can stall converting a completed dissertation into articles published in peer-reviewed journals. This descriptive article, second in a three-part series, briefly explores a behavior (procrastination) that can block writing goals. Procrastination, and its parallel perfectionism, often entails negative self-talk. Procrastination may result in short-term mood repair and emotional self-regulation by avoidant behavior. However, there are negative linked consequences for health and well-being beyond stymied writing efforts. Recommendations are offered to minimize self-limiting behaviors and shift to a growth mindset that contributes to accomplishing journal publication. Intended goals, such as the intent to publish in a peer-reviewed journal, are enhanced by compassionate self-review. Self-reflection that shifts one’s internal view toward a growth mindset includes forgiving oneself for stumbles along the dissertation pathway, noticing prior success in writing and revising a document, reframing tasks as achievable, and embracing positive emotions embedded in curiosity and personal initiative. Compassion toward oneself requires a personal commitment to meeting challenges with greater self-kindness and self-acceptance. Key Words: Growth mindset, journal publishing, procrastination, self-control

Five thousand years of minimal access surgery: 1850 to 1990: Technological developments.

This is the second of a three-part series that charts the history of minimal access surgery from antiquity to current times. Although rapid developments in laparoscopic and robotic surgery have transformed surgical care over the last 30 years, our predecessors made significant advances in their time which set the principles for modern practice. Part I of this series described how ancient medical practitioners developed simple instruments, from metal or wood, for viewing body cavities. Improvements in the use of metal, glass and lighting allowed for inspection of deeper parts of the body. This second part of the series will show how advances in electrical technology allowed the development of improved lighting for endoscopy and laparoscopy along with the use of electrocautery for a wide range of therapeutic procedures.

Five thousand years of minimal access surgery: 3000BC to 1850: early instruments for viewing body cavities.

Surgeons and their patients recognise that one of the major advances in surgical technique over the last 20 years has been the growth of minimal access surgery by means of laparoscopic and robotic approaches. Partnerships with industry have facilitated the development of advanced technical instruments, light sources, recording devices and optics which are almost out of date by the time they are introduced to surgical practice. However, lest we think that technological innovation is entirely a modern concept, we should remember that our predecessors were masters of their craft and able to apply new technologies to surgical practice. The history of minimal access surgery can be traced back to approximately 5000 years ago and this review aims to remind us of the achievements of historical doctors and engineers, as well as bring more modern developments to wider attention.This review will comprise a three-part series:Part I 3000BC to 1850 Early instruments for viewing body cavitiesPart II 1850 to 1990 Technological developmentsPart III 1990 to present Organisational issues and the rise of the robots.

The main suppliers of artificial intelligence developments are identified and characterized, and market offers for the banking sector are also analyzed. Data on shares of companies implementing artificial intelligence developments are summarized, and an example of the use of such developments in exchange activities is given. Mechanisms of state stimulation of applied artificial intelligence development and creation of alliances and consortia of the largest scientific and technological corporations to accelerate these developments are considered separately.

Orthodontic Conundrums Part 1: Transposition – an Update on Presentation and Treatment Modalities

This is the first article in a three-part series considering uncommon dental anomalies and treatment approaches. Dental transpositions are rare anomalies which may present to the general dental practitioner or orthodontist. The management of transpositions is dependent on several factors, including the sub-type, severity and the other salient features of the malocclusion. Transposition may either be accepted or orthodontically corrected and the adoption of either approach must be preceded by thorough assessment of the patient. CPD/Clinical Relevance: The presentation and management of transposition is variable. The general dental practitioner must be aware of the clinical features of a developing transposition as certain treatment options are only possible before the transposition is fully established. In addition, the orthodontist must be mindful of the potential for iatrogenic harm if these dental anomalies are managed injudiciously.

The Use of Technology in Managing Diabetes in Youth Part 3-Special Considerations: Integration Into the School Setting.

The advantages of continuous glucose monitoring (CGM) and insulin pump systems have increased the popularity of these devices among students in the school setting. The use of diabetes technology at school and school-sponsored activities strengthens the student's consistent use of the technology and increases the overall beneficial effects. The school nurse has many considerations when supporting the student with diabetes technology. Integrating this technology into diabetes care at school can be complex with collaboration and safety considerations fundamental to success. This is the third article in a three-part series on the use of technology in managing diabetes in youth. The first article described CGM devices and provided tips for the school nurse in incorporating CGM into the student's individualized healthcare plan. The second article summarized insulin pump technologies, from conventional insulin pump therapy to advance automated insulin delivery systems and described keys to success with insulin pump technologies. The purpose of this article is to address some special considerations for facilitating the use of diabetes technology in the school setting. Topics to be discussed are tips on including insulin pump therapy in the student's individualized healthcare plan, safe use of diabetes technology during physical activity, and implications for school nursing practice.

Science-Driven Societal Transformation, Part I: Worldview

Humanity faces serious social and environmental problems, including climate change and biodiversity loss. Increasingly, scientists, global policy experts, and the general public conclude that incremental approaches to reduce risk are insufficient and transformative change is needed across all sectors of society. However, the meaning of transformation is still unsettled in the literature, as is the proper role of science in fostering it. This paper is the first in a three-part series that adds to the discussion by proposing a novel science-driven research-and-development program aimed at societal transformation. More than a proposal, it offers a perspective and conceptual framework from which societal transformation might be approached. As part of this, it advances a formal mechanics with which to model and understand self-organizing societies of individuals. While acknowledging the necessity of reform to existing societal systems (e.g., governance, economic, and financial systems), the focus of the series is on transformation understood as systems change or systems migration—the de novo development of and migration to new societal systems. The series provides definitions, aims, reasoning, worldview, and a theory of change, and discusses fitness metrics and design principles for new systems. This first paper proposes a worldview, built using ideas from evolutionary biology, complex systems science, cognitive sciences, and information theory, which is intended to serve as the foundation for the R&D program. Subsequent papers in the series build on the worldview to address fitness metrics, system design, and other topics.

Improving Small Satellite Communications and Tracking in Deep Space—A Review of the Existing Systems and Technologies With Recommendations for Improvement. Part III: The Deep Space Network

This article is the third of a three-part series in which we present the results of a study exploring concepts for improving communications and tracking capabilities of deep space SmallSats. In Part I, we discussed SmallSat direct-to-Earth links as well as SmallSat communications equipment, and provided recommendations for future work. In Part II, we focused on SmallSat navigation options, disruption tolerant networking, proximity links, and the use of the communication link for science observations. In Part III, we focus on ground support of deep space SmallSats. We present a brief overview of NASA's deep space network (DSN) along with concepts for adapting the DSN to improve support for SmallSats. We discuss approaches for increasing the DSN's efficiency in handling the anticipated increase in SmallSat communications, such as reducing setup and teardown times for a communications pass, and reducing DSN time allocated to Doppler and range measurements. A new demand access operational paradigm is proposed, which is more consistent with SmallSat communications requirements and will facilitate the DSN handling of larger numbers of spacecraft. Finally, we present the conclusion of the study as a list of recommendations to improve SmallSat communications and tracking.

Implementing Monetary Policy in an "Ample-Reserves" Regime: The Basics (Note 1 of 3)

The FOMC has stated that it intends to continue implementing monetary policy in a regime with an ample supply of reserves. This Note, the first in a three-part series, provides an introductory discussion of what it means to implement policy in such a regime and how the Fed ensures interest rate control in an environment with an ample supply of reserves in the banking system.

Improving Small Satellite Communications and Tracking in Deep Space—A Review of the Existing Systems and Technologies With Recommendations for Improvement. Part II: Small Satellite Navigation, Proximity Links, and Communications Link Science

This article is the second of a three-part series in which we present the results of a study exploring concepts for improving communications and tracking capabilities of deep space SmallSats. In Part I, we discussed SmallSat direct-to-earth links and SmallSat communications equipment, and provided recommendations for future work. In Part II, we focus on SmallSat navigation options, Disruption Tolerant Networking (DTN), proximity links, and the use of the communication link for science observations, and we provide recommendations for future work. We have examined both radio and optical navigation options, and considered autonomous and semiautonomous navigation to reduce operational costs for planetary SmallSats. We note that communication link resilience to delay and disruption enhances spacecraft autonomy; therefore, we have provided a discussion of DTN to indicate that using DTN allows for automated data transmission and recovery, therefore, reducing manual operations. SmallSats in deep space may utilize a relay spacecraft for communications with earth or function as a relay for landed and in-orbit assets. We present a detailed examination of relay proximity links and networks where we address both proximity hardware and networking scenarios. The proximity link features that we examine include the network architecture and its relationship to DTN, proximity radios and antennas, communications link performance, and proximity navigation. The use of the communication link for science has been practiced by primary missions in deep space scenarios. (Two examples of past planetary radio science experiments can be found in the following: https://solarsystem.nasa.gov/missions/cassini/mission/spacecraft/cassini-orbiter/radio-science-subsystem/ and https://www.boulder.swri.edu/pkb/ssr/ssr-rex.pdf) Likewise, SmallSats can offer their radio links for radio science investigations. This article provides a brief introduction to radio science and presents the prerequisite features necessary for radio science observations by SmallSats. We conclude with nine recommendations based on the findings of the study. These recommendations are guidelines on the design, implementation, and operation of deep space SmallSat communication links. The adoption of some or all of the guidelines should result in an enhanced communication and tracking capability for the deep space SmallSat missions.
