The aim of this review is threefold. On the one hand, we intend it to serve as a gentle introduction to the Interacting Quantum Atoms (IQA) methodology for those unfamiliar with it. Second, we expect it to act as an up-to-date reference of recent developments related to IQA. Finally, we want it to highlight a non-exhaustive, yet representative set of showcase examples about how to use IQA to shed light in different chemical problems. To accomplish this, we start by providing a brief context to justify the development of IQA as a real space alternative to other existent energy partition schemes of the non-relativistic energy of molecules. We then introduce a self-contained algebraic derivation of the methodological IQA ecosystem as well as an overview of how these formulations vary with the level of theory employed to obtain the molecular wavefunction upon which the IQA procedure relies. Finally, we review the several applications of IQA as examined by different research groups worldwide to investigate a wide variety of chemical problems.

There are abundant controversial treatises bearing on Soviet-Nazi relationships, with their consequent effect on world power politics. The observations summarized herewith may shed light on recent developments, suggesting the cataclysm that today shakes the world.(1) Mutual distrust on the part of the British and French governments on the one hand and the Soviet régime on the other, dating back to the Revolution of October 7, 1917. In a large measure, this is due to the fact that there have been, and there are now, active Communists and sympathizers in England and in the United States to propagandize the Soviets' point of view and to apologize for the faults of the Stalin régime. Conversely, there have never been, and there are not now, democratic agents and sympathizers at large in Soviet Russia to represent and interpret Western ideas of democracy either to the Russian people or to the Soviet leaders. There is a school of thought represented by distinguished scholars in America and England which contends that the Soviet overtures at Geneva looking toward disarmament were naively insincere. Ambassador Litvinov's personal motives were, however, beyond reproach.

In the last decade and a half, thin film research, particularly research into problems associated with epitaxy, has developed from a simple empirical process of determining the conditions for epitaxy into a complex analytical and experimental study of the nucleation and growth process on the one hand and a technology of very great importance on the other. During this period the thin films group of the University of Chile has studied the epitaxy of metals on metal and insulating substrates. The development of the group, one of the first research groups in physics to be established in the country, has parallelled the increasing complexity of the field.The elaborate techniques and equipment now needed for research into thin films may be illustrated by considering the plant and facilities of this group as characteristic of a good system for the controlled deposition and study of thin films.

COVID 19 has raised the profile of biosecurity. However, biosecurity is not only about protecting human life. This issue brings together mini-reviews examining recent developments and thinking around some of the tools, behaviours and concepts around biosecurity. They illustrate the multi-disciplinary nature of the subject, demonstrating the interface between research and policy. Biosecurity practices aim to prevent the spread of harmful organisms; recognising that 2020 is the International Year of Plant Health, several focus on plant biosecurity although invasive species and animal health concerns are also captured. The reviews show progress in developing early warning systems and that plant protection organisations are increasingly using tools that compare multiple pest threats to prioritise responses. The bespoke modelling of threats can inform risk management responses and synergies between meteorology and biosecurity provide opportunities for increased collaboration. There is scope to develop more generic models, increasing their accessibility to policy makers. Recent research can improve pest surveillance programs accounting for real-world constraints. Social science examining individual farmer behaviours has informed biosecurity policy; taking a broader socio-cultural approach to better understand farming networks has the potential to change behaviours in a new way. When encouraging public recreationists to adopt positive biosecurity behaviours communications must align with their values. Bringing together the human, animal, plant and environmental health sectors to address biosecurity risks in a common and systematic manner within the One Biosecurity concept can be achieved through multi-disciplinary working involving the life, physical and social sciences with the support of legislative bodies and the public.

Abstract The intersection between foreign investment and human rights is gaining attention, as is evident from an increasing number of investment treaty awards analysing legal issues relating to human rights. In the recent International Centre for the Settlement of Investment Disputes (ICSID) arbitration of Bear Creek v Peru, Philippe Sands QC posited, in a dissenting opinion, that the investor’s contribution to events—ie protests against its allegedly adverse environmental impact and disregard of indigenous rights, namely resulting from its ‘inability to obtain a “social licence”’—which led to the unlawful expropriation of its investment, was ‘significant and material’. He further noted that the investor’s ‘responsibilities are no less than those of the government’ and found that damages should thus be reduced. Last year, the Netherlands adopted a new model bilateral investment treaty (BIT), which allows tribunals to ‘take into account non-compliance by the investor with the UN Guiding Principles on Business and Human Rights and the OECD Guidelines for Multinational Enterprises’ when assessing damages. These recent developments shed light on how states and tribunals, as part of their decision-making process, can take into account human rights in practice, and crucially in respect of damages analyses. By first dissecting the concept of contributory fault, then shedding light on the intersection of investment treaty law and human rights, as elucidated in recent jurisprudence, this article questions whether there now exists a gateway for human rights obligations (soft or hard) in the investment treaty arbitration realm through the concept of contributory fault.

The current study intends to contribute to a better understanding of the medical tourism experience. In particular, this study uses data from a survey-based study conducted on a sample of 1,209 medical tourists in Croatia. On the one hand, this study aims to explore and shed light on the decision-making process of medical tourists, and, on the other hand, to reveal which elements of both the medical institution and the destination where it is located, have largest potentials to drive medical tourist delight and/or frustration, in accordance with the three-factor theory of customer satisfaction.

Starting from previous studies in professional caregivers of people with dementia and other diseases in institutionalized centers of different regions, the aim of this study was to compare burnout levels that workers present depending on the center, to create a caregiver profile with high professional accomplishment and to describe the quality of life that residents perceive Murcia and Barcelona. The instruments used were the Maslach Burnout Inventory (MBI), the Professional Caregiver Survey developed ad hoc and the Brief Questionnaire of Quality of Life (CUBRECAVI in Spanish) on residents. The results show, on the one hand, that levels of professional accomplishment may be paradoxically higher in the case of catastrophe and, on the other hand, the 98.2% of users are satisfied with the residence in which is located and 81.8% with the manner in which occupy the time. The conclusions that are extrapolated from the study shed light on the current situation of workers and residents and the influence that an earthquake can have on them.

Businesses grounded upon multisided platforms (MSPs) are found in a growing number of industries, thanks to the recent developments in Internet and digital technologies. Digital MSPs enable multiple interactions among users of different sides through information and communication technologies. The understanding of the characteristics and constituents of MSPs is fragmented along different literature streams. Moreover, very few empirical studies have been carried out to date. In order to fill this gap, this paper presents a three-level framework that describes a digital MSP. The proposed framework is based on literature analysis and multiple case study. On the one hand, the framework can be used to describe MSP as it provides an operationalization of the concept through the identification of specific dimensions, variables and items; on the other hand, it can be used as an assessment tool by practitioners, as exemplified by the three empirical applications presented in this paper.

Recent developments in contemporary theology and theological ethics have directed academic attention to the interrelationships of theological claims, on the one hand, and core community-forming practices, on the other. This article considers the value for theology of attending to practice at the boundaries, the margins, or, as we prefer to express it, the threshold of a community’s institutional or liturgical life. We argue that marginal or threshold practices can offer insights into processes of theological change – and into the mediation between, and reciprocal influence of, ‘church’ and ‘world’. Our discussion focuses on an example from contemporary British Quakerism. ‘Threshing meetings’ are occasions at which an issue can be ‘threshed out’ as part of a collective process of decision-making. Drawing on a 2015 small-scale study (using a survey and focus group) of British Quaker attitudes to and experiences of threshing meetings, set in the wider context of Quaker tradition, we interpret these meetings as a space for working through – in context and over time – tensions within Quaker theology, practice and self-understandings, particularly those that emerge within, and in relation to, core practices of Quaker decision-making.

The article is devoted to topical issues of the development of the ideology of feminism in modern conditions. The purpose of the work is to identify the factors of the dynamics of the ideology of feminism at the beginning of the 21st century. The main versions of classical feminism are characterized: liberal, Marxist and radical. There is a close connection between the origins of feminism and Marxism, but even in the early period the interaction of these ideological and political movements was problematic. There is also an interaction of feminism with new social movements in the West in the 20th century. The contradictory consequences of the development of the women's movement for the ideology of feminism are noted: on the one hand, the actualization of the feminist agenda in Western countries created the conditions for significant successes in protecting women's rights and recognizing feminism as a real political force, on the other hand, these same successes reduced the relevance of the liberal version of feminism. Recent developments in Europe have a significant impact on the feminist agenda. Globalization and, in particular, the migration crisis of the 2010s are considered as one of the new factors in the ideological dynamics of feminism. The influx of migrants from Muslim countries not only places a burden on state budgets and reduces the level of security of life on the continent, but also erodes the civilizational identity of European society. Muslim migrants do not seek to integrate into European society, often ignore the fundamental values of European civilization, and above all, women's equality. This situation creates incentives not only to renew the political goals of feminists, but also to revise the ideological foundations of their ideology itself. In particular, it is possible to move away from the traditional reliance on left-wing political slogans and replace the popular Marxist phraseology among radical Islamists with values related to the protection of democratic gains of European society.

: The synthesis of ester containing heterocyclic compounds via multicomponent reaction is one of the most preferable process in the synthetic organic chemistry and medicinal chemistry. Compounds containing ester linkage have a wide range of biological application in the pharmaceutical field. Therefore, many method have been developed for the synthesis of these type of derivatives. However, some of them are carried out in the presence of toxic solvents and catalysts, with lower yields, longer reaction times, low selectivities and by-products. Thus, the development of new synthetic methods for the ester synthesis is required in the medicinal chemistry. As we know, multicomponent reactions (MCRs) are a powerful tool towards the one-pot ester synthesis, so in this article we have reviewed the recent developments in ester synthesis. This work covers selected explanation of methods via multicomponent reactions to explore the methodological development in ester synthesis.
