Novel Structures

The evolution of organometallic chemistry during the second half of the 20th century has transformed chemical science and technology to a degree and in ways that have rarely been matched throughout the history of chemistry. These include the discovery of radically new types of chemical compounds; novel structures and bonding modes; unprecedented reactivity patterns; unsuspected roles of organometallic chemistry in biology; powerful new synthetic methodologies; new materials; and whole new classes of catalysts and catalytic processes of extraordinary versatility and selectivity. The impact of these developments, which still are unfolding, has been truly revolutionary. Some milestones in this remarkable chapter of chemical history, as well as challenges and opportunities confronting organometallic chemistry today, will be examined.

The Impact

Following a long history of using various strategies and policies for diversification and seasonal adjustment in the face of the challenges of achieving economic, social, and environmental sustainability, sun and beach destinations should also consider targeting the wellness tourism market as a post pandemic opportunity and long-term solution. Salou is a mature sun and beach destination in the Mediterranean, but one which, for some time, has had an increasing commitment to family and sports tourism as a result of a strategic renewal process. Now, with the impact of the coronavirus pandemic, the destination management organization is considering the evolution of the model, the internalization of sustainability as a fundamental value, and the impact of different markets. In this study, we examined the challenges the Salou Tourist Board has faced during the development of a post pandemic model for sustainable tourism and what strategies it has adopted in response. We also considered the opportunities and competitive advantages that Salou has in the field of wellness tourism. The results obtained should encourage the continuation of work that promotes the environmental axis of sustainability and adds value to the natural resources on which it depends, including the sea and the landscape, while maintaining the environmental quality of the resources.

Health social work is a subspecialization of social work concerned with a person's adjustment to changes in one's health and the impact this has on that person's social network. Social workers in every setting must be ready to assist individuals and families adjusting to illness and coping with medical crises. This entry provides a brief overview and history of health social work and describes the settings and roles where this work is practiced. Significant challenges and opportunities in clinical care, research, education, and policy are discussed. Standards and guidelines for quality practice are then noted.

We present first results of an implementation of chemical evolution in a cosmological hydrodynamical code, focusing the analysis on the effects of cooling baryons according to their metallicity. We found that simulations with primordial cooling can underestimate the star formation rate from z < 3 and by up to ≈ 20%. We constructed simulated spectra by combining the star formation and chemical history of galactic systems with spectral synthesis models and assess the impact of chemical evolution on the energy distribution.

The Impact

It is now 49 years since Johan Heyns’s Sterwende Christendom? [Dying Christendom] was published (1969) in which he traced the history of secularisation and its impact on the theology of his time and 36 years since the publication (1982) of the first volume of his Teologiese etiek [Theological ethics] in which he discussed the impact of secularisation on ethics. In this article, the topic of the impact of secularisation on Christian ethics is revisited. Account is taken of research conducted on the secularising impact of modernisation since then. Although empirical research points to the fact that it is not true that modernisation inevitably leads to the complete demise of religious faith and ethics, and also not that there is today absolutely no room for religious influences in the different social orders, it does not mean that it is a case of business as usual for Christian ethics. It cannot be denied that modernisation has a significant effect on the shape of Christian ethics in the contemporary world. And it can also not be denied that in most contemporary liberal democratic societies, including South Africa, the public role of Christian ethics is restricted. Some of the challenges – and opportunities – present-day realities pose to South African churches and their members are identified and discussed.Intradisciplinary and/or interdisciplinary implications: On account of the pluralising and fragilising impact of modernisation on Christian faith, the discipline of Christian ethics should today criticise the absolutising of Christian ethical beliefs and encourage Christians to actively support consensus seeking on moral values in the workplace and in society.

Abstract. Background: Self-esteem is a major contributor to risk for repeated suicide attempts. Prior research has shown that awareness of stigma is associated with reduced self-esteem among people with mental illness. No prior studies have examined the association between self-esteem and stereotype awareness among individuals with past suicide attempts. Aims: To understand the relationship between stereotype awareness and self-esteem among young adults who have and have not attempted suicide. Method: Computerized surveys were administered to college students (N = 637). Linear regression analyses were used to test associations between self-esteem and stereotype awareness, attempt history, and their interaction. Results: There was a significant stereotype awareness by attempt interaction (β = –.74, p = .006) in the regression analysis. The interaction was explained by a stronger negative association between stereotype awareness and self-esteem among individuals with past suicide attempts (β = –.50, p = .013) compared with those without attempts (β = –.09, p = .037). Conclusion: Stigma is associated with lower self-esteem within this high-functioning sample of young adults with histories of suicide attempts. Alleviating the impact of stigma at the individual (clinical) or community (public health) levels may improve self-esteem among this high-risk population, which could potentially influence subsequent suicide risk.

This chapter traces the early history of state-sponsored informational filmmaking in Denmark, emphasising its organisation as a ‘cooperative’ of organisations and government agencies. After an account of the establishment and early development of the agency Dansk Kulturfilm in the 1930s, the chapter considers two of its earliest productions, both process films documenting the manufacture of bricks and meat products. The broader context of documentary in Denmark is fleshed out with an account of the production and reception of Poul Henningsen’s seminal film Danmark (1935), and the international context is accounted for with an overview of the development of state-supported filmmaking in the UK, Italy and Germany. Developments in the funding and output of Dansk Kulturfilm up to World War II are outlined, followed by an account of the impact of the German Occupation of Denmark on domestic informational film. The establishment of the Danish Government Film Committee or Ministeriernes Filmudvalg kick-started aprofessionalisation of state-sponsored filmmaking, and two wartime public information films are briefly analysed as examples of its early output. The chapter concludes with an account of the relations between the Danish Resistance and an emerging generation of documentarists.

The Impact

This article is part of a special Left History series reflecting upon changing currents and boundaries in the practice of left history, and outlining the challenges historians of the left must face in the current tumultuous political climate. This series extends a conversation first convened in a 2006 special edition of Left History (11.1), which asked the question, “what is left history?” In the updated series, contributors were asked a slightly modified question, “what does it mean to write ‘left’ history?” The article charts the impact of major political developments on the field of left history in the last decade, contending that a rising neoliberal and right-wing climate has constructed an environment inhospitable to the discipline’s survival. To remain relevant, Palmer calls for historians of the left to develop a more “open-ended and inclusive” understanding of the left and to push the boundaries of inclusion for a meaningful historical study of the left. To illustrate, Palmer provides a brief materialist history of liquorice to demonstrate the mutability of left history as a historical approach, rather than a set of traditional political concerns.
