‘Can we doubt … that individuals having any advantage, however slight, over others, would have the best chance of surviving and of procreating their kind?’ In the Origin of Species (1859) Darwin challenged many of the most deeply held beliefs of the Western world. His insistence on the immense length of the past and on the abundance of life-forms, present and extinct, dislodged man from his central position in creation and called into question the role of the Creator. He showed that new species are achieved by natural selection, and that absence of plan is an inherent part of the evolutionary process. Darwin's prodigious reading, experimentation, and observations on his travels fed into his great work, which draws on material from the Galapagos Islands to rural Staffordshire, from English back gardens to colonial encounters. The present edition provides a detailed and accessible discussion of his theories and adds an account of the immediate responses to the book on publication. The resistances as well as the enthusiasms of the first readers cast light on recent controversies, particularly concerning questions of design and descent.

Over the past decades, the BRICS (Brazil, Russia, India, China, South Africa) countries have experienced significant economic growth. However, their political voices in global governance have not grown on par with their economic surge. The contributions to the symposium ‘The BRICS, Global Governance, and Challenges for South–South Cooperation in a Post-Western World’ argue there is a quest for emerging markets and developing countries to play a more significant role in global governance. There is a widening gap between the actual role of emerging markets and developing countries in the global system and their ability to participate in that system. However, for the moment, various domestic and international political-economic challenges limit this quest. To understand why this is the case, one should understand the BRICS phenomenon in the broader context of the global power shift towards the Global South.

In the past two decades bilingual education has become an educational movement and a field of academic inquiry of remarkable growth throughout the world. At first glance this appears to be the outcome of the increasingly hegemonic role of a few languages like English in the western world and countries economically affiliated to it, Russian in the multilingual republics of the Soviet Union, and Putonghua in the People's Republic of China. But a closer look at the first of these areas—the one better known to us—shows how complex the dynamics of language spread and language change are in diverse sociopolitical contexts.

Based on an oral history study that retrospectively explores the life histories of former orphans in the city of Ghent (Belgium) after the Second World War, we analyse and critique the role of historical research in the current apology trend. Due to the crucial role of (oral) history in these out-of-home care inquiries, these official public apologies, offered by the state as an attempt to come to terms with the past, deserve some specific academic attention in social work research. By inquiring into historical abuse in child welfare and educational institutions, governments of the Western world attempt to close a rather dark chapter in their national histories. Relying on research insights emerging from our research project with formerly orphaned children, we argue that it is impossible to puzzle together one common historical narrative. Moreover, we discovered that the history of the Ghent orphanages is still very much debated and alive more than 35 years after their doors were closed. In this article, we tease out how life histories can play a role in Western welfare states today. We therefore explore the relevance of the notion of ‘presence’ in order to rethink the relationship between the past and the present.

Selenium is a fascinating element that has a long history, most of which documents it as a deleterious element to health. In more recent years, selenium has been found to be an essential element in the diet of humans, all other mammals, and many other life forms. It has many health benefits that include, for example, roles in preventing heart disease and certain forms of cancer, slowing AIDS progression in HIV patients, supporting male reproduction, inhibiting viral expression, and boosting the immune system, and it also plays essential roles in mammalian development. Elucidating the molecular biology of selenium over the past 40 years generated an entirely new field of science which encompassed the many novel features of selenium. These features were (1) how this element makes its way into protein as the 21st amino acid in the genetic code, selenocysteine (Sec); (2) the vast amount of machinery dedicated to synthesizing Sec uniquely on its tRNA; (3) the incorporation of Sec into protein; and (4) the roles of the resulting Sec-containing proteins (selenoproteins) in health and development. One of the research areas receiving the most attention regarding selenium in health has been its role in cancer prevention, but further research has also exposed the role of this element as a facilitator of various maladies, including cancer.

In the Baltic countries, the golden jackal (Canis aureus) was first recorded in Estonia on 28 February 2013 and three specimens of golden jackal were hunted in Latvia in 2014. The first golden jackal in Lithuania was hunted on 7 February 2015. The species of the golden jackal was identified using morphological and mitochondrial DNA control region (CR1) analysis. In Lithuania, hunting of these animals is permitted throughout the year. Few studies in the past revealed the potential role of the golden jackal as a carrier of intestinal helminths, parasites, and zoonotic diseases. In this study, the presence of tick-borne pathogens and other parasites in golden jackal specimen were investigated. No pathogens (Anaplasma phagocytophilum, Babesia sp., Bartonella sp.) were found in the spleen of the golden jackal. However, the flukes Apophallus donicus, nematodes Uncinaria stenocephala, and unidentified individuals of class Cestoda were detected. Helminths A. donicus and U. stenocephala are not new species for Lithuania and neighbouring territories.

Ancient Times

We constructed a simple evolutionary system, “evoloop,” on a deterministic nine-state five-neighbor cellular automata (CA) space by improving the structurally dissolvable self-reproducing loop we had previously contrived [14] after Langton's self-reproducing loop [7]. The principal role of this improvement is to enhance the adaptability (a degree of the variety of situations in which structures in the CA space can operate regularly) of the self-reproductive mechanism of loops. The experiment with evoloop met with the intriguing result that, though no mechanism was explicitly provided to promote evolution, the loops varied through direct interaction of their phenotypes, smaller individuals were naturally selected thanks to their quicker self-reproductive ability, and the whole population gradually evolved toward the smallest ones. This result gives a unique example of evolution of self-replicators where genotypical variation is caused by precedent phenotypical variation. Such interrelation of genotype and phenotype would be one of the important factors driving the evolutionary process of primitive life forms that might have actually occurred in ancient times.

Abstract: In this article, we discuss the results of studying the flora of the Absheron Peninsula. The dynamics of the species composition over the past 70 years is considered. We were unable to find 206 species in the habitats previously recorded by Karyagin in 1952. We included 678 species in the list of flora of the Absheron Peninsula, of which 599 species were classified as native flora. In accordance with the direction of the dynamics of their habitats, we distinguish five groups of native flora species: Extinct (not found on the territory of Absheron for more than 50 years) – seven species, endangered (disappeared in several previously known localities) - 130 species, stable (found in previously known localities) – 209 species, dynamic (disappeared in previously known localities, but found in new localities) - 191 species, progressive (found in previously known localities and found in new localities) - 47 species. It is well known that for any region the adventive element of the flora is more dynamic than the native one. In total, we recorded 97 adventive species for the Absheron peninsula, of which 23 were new species for the flora of the region. We draw attention to the fact that since the beginning of the XIX century, the relative role of various sources of replenishment of the adventitious flora has changed. However, with the beginning of the new millennium, the contribution of railways to the formation of the advent component is noticeably decreasing.The number of new species entering the territory of the Absheron Peninsula by rail is radically decreasing. During the period covering 9 years (from 2012 to 2020), we were not able to find a single new adventive species that was intrude by rail. On the other hands, the activity of cultivated ornamental trees, shrubs and herbaceous plants became more clearly visible. There is a significant increase in the role landfills and wastelands in the formation of the adventive flora of the region

The role of electron microscopy and associated techniques is assured in diagnostic pathology. At the present time, most of the progress has been made on tissues examined by transmission electron microscopy (TEM) and correlated with light microscopy (LM) and by cytochemistry using both plastic and paraffin-embedded materials. As mentioned elsewhere in this symposium, this has revolutionized many fields of pathology including diagnostic, anatomic and clinical pathology. It began with the kidney; however, it has now been extended to most other organ systems and to tumor diagnosis in general. The results of the past few years tend to indicate the future directions and needs of this expanding field. Now, in addition to routine EM, pathologists have access to the many newly developed methods and instruments mentioned below which should aid considerably not only in diagnostic pathology but in investigative pathology as well.

According to the latest forecasts, it will take 10 years for the world economy to get back to “decent shape”. Some more critical estimates suggest that the whole western world will have a “colossal mess” within the next 5–10 years. Regulators of some major countries significantly and over a short time‑period changed their forecasts for the worse which means that uncertainty in the outlook for the future persists. Indeed, the intensive anti‑crisis measures have reduced the severity of the past problems, however the problems themselves have not disappeared. Moreover, some of them have become more intense — the eurocrisis, excessive debts, global liquidity glut against the backdrop of its deficit in some of market segments. As was the case prior to the crisis, derivatives and high‑risk operations with “junk” bonds grow; budget problems — “fiscal cliff” in the US — and other problems worsen. All of the above forces the regulators to take unprecedented (in their scope and nature) steps. Will they be able to tackle the problems which emerge?

The Relationship

The rise of e-commerce has brought considerable changes to the relationship between firms and consumers, especially within international business. Hence, understanding the use of such means for entering foreign markets has become critical for companies. However, the research on this issue is new and so it is important to evaluate what has been studied in the past. In this study, we conduct a systematic review of e-commerce and internationalisation studies to explicate how firms use e-commerce to enter new markets and to export. The studies are classified by theories and methods used in the literature. Moreover, we draw upon the internationalisation decision process (antecedents-modalities-consequences) to propose an integrative framework for understanding the role of e-commerce in internationalisation
