Plastic has been present in our lives for the past century as an essential material for many commodity items. However, the same properties that make plastic convenient are also responsible for the current dramatic environmental pollution. As an alternative, most of the world has been working with technological innovations, and one of its strategies is the use of bioplastics. Despite being considered environmentally beneficial by some people, there are still developments and discussions that need to be made. This article aims to present a legislative review and discusses the difficulty in implementing policies related to the incentive of the bioplastics market, as well as presenting some state and municipal laws, already prohibiting single-use plastics in Brazil. These laws aim to encourage the substitution of these plastics for biodegradable ones. However, it still has gaps and a lack of clarification on how the banning of disposable plastics and their substitution will be beneficial since composting is still an incipient process in the country. It is also the purpose of this article to discuss the challenges in the context of the Circular Economy, as well as the potential solution based on the creation of public policies aimed at improving waste management, in addition to clearer legislation on alternatives to single-use plastics.

Today, many people enjoy an easy lifestyle. However, this comfort has come with a price because of plastic that is thrown away after a single use. As such, governments around the world have pushed for biodegradable plastics to be produced, especially for food packaging, and these can be easily seen in supermarkets, for example. Using plastic for only one time has resulted in environmental pollution. To solve this problem, polylactic acid (PLA) has been introduced as an alternative bio-based plastic to replace artificial petroleum-based plastics. PLA comes from renewable resources and is biodegradable under certain conditions. Furthermore, the development of the properties of PLA could solve problems related to its weakness in packaging applications. This editorial proposes expansion of the property attributes of PLA to include hygienic character, through the addition of antibacterial agents. This can be done by introducing two alternative approaches for waste management: PLA recycling and degradation. However, some key research is still needed to improve the properties and waste management of PLA relative to the effectiveness of its reprocessing and acceleration of its (bio)degradation.

Over the past century, democracy spread around the world in turbulent bursts of change, sweeping across national borders in dramatic cascades of revolution and reform. This book offers a new global-oriented explanation for this wavelike spread and retreat—not only of democracy but also of its twentieth-century rivals, fascism, and communism. The book argues that waves of regime change are driven by the aftermath of cataclysmic disruptions to the international system. These hegemonic shocks, marked by the sudden rise and fall of great powers, have been essential and often-neglected drivers of domestic transformations. Though rare and fleeting, they not only repeatedly alter the global hierarchy of powerful states but also create unique and powerful opportunities for sweeping national reforms—by triggering military impositions, swiftly changing the incentives of domestic actors, or transforming the basis of political legitimacy itself. As a result, the evolution of modern regimes cannot be fully understood without examining the consequences of clashes between great powers, which repeatedly—and often unsuccessfully—sought to cajole, inspire, and intimidate other states into joining their camps.

In many parts of the world, fertility has declined in important ways in the past century. What are the consequences of this demographic change? Our study expands the empirical basis for understanding the relationship between number of siblings in childhood and social outcomes among adults. An important recent study found that for each additional sibling an individual grows up with, the likelihood of divorce as an adult declines by 3%. We expand this work by (a) determining whether the original pattern replicates in the National Longitudinal Study of Adolescent to Adult Health and (b) extending the analysis beyond divorce to consider whether growing up with siblings is related to prosocial adult behaviors (relationships with parents, friends, and views on conflict management with one’s partner). Our results confirm a negative association between number of siblings and divorce in adulthood. We find mixed results related to other prosocial adult behaviors.

It seems to me that the study of writing is about where the study of language was before the development of linguistics over the past century-and-a-bit. Everyone we know knows how to write, and therefore everyone we know thinks they know about writing. This paper looks at how writing has been presented to the general public, and how it has been treated in linguistics since the first real textbook of 1933.

The world ecological problem of waste accumulation, environmental pollution and the need to develop a circular economy are described. The aim of the article is to show the advantage of using a circular economy in the management of the national economy. It is substantiated that resource management should radically change from a linear model of accept-use-dispose to a more stable, circular model. It is proved that the principles of circular economy are not based on the management of material and waste flows, but on more valuable methods, such as maintenance, recycling and reuse. Different models of circular economy and their shortcomings are considered. Based on practical world experience in implementing the concept of circular economy, 5 main circular business models are identified. It has been established that circular supply chains that minimize waste and seek to reuse, repair and recycle where waste cannot be prevented should be more sustainable than the linear systems they replace. It was found that in the absence of effective resource management, the current environmental situation will lead to fatal consequences, which confirms the need for public administration to ensure the use of a circular economy.

The use of plants to prevent and treat illnesses has been known since time immemorial. Blackseed has been used in different civilizations around the world for centuries. The curative properties of blackseed were mentioned in the Bible and further elaborated on by Prophet Mohammed (PBUH) as “Hold on to the use of blackseed, as it has a remedy for every illness except death”. Extensive research conducted over the past century into the phytochemistry of blackseed has identified many active ingredients and confirmed its pharmacological action in the treatment of a vast range of illness conditions across the different systems of the body, including the prevention and treatment of cancer, and optimum functioning of the immune system. Furthermore, the Tibb philosophical principles highlight the ability of the body’s inherent self-healing capacity, known as Physis, and the intricate functioning of the human body, based on the temperamental and humoral theory. This paper emphasizes the importance of Physis, and its role in the maintenance and restoration of health with the regular intake of blackseed, highlighting why blackseed can be a cure for all illnesses except death. Keywords: Blackseed, phytochemistry, pharmacological action, Tibb philosophical principles.

IT is a pity that Hume, who carried the Cartesian system of philosophy to its logical conclusion, lived too early to contemplate the discoveries of the past century in Egypt and Babylonia, for he would readily have understood and assimilated the ancient processes of thought which arose at the dawn of history in Western Asia--‘ And no truth appears to me more evident ’, he said, ‘ than that beasts are endowed with thought and reason as well as man ’. The arguments are developed in section XVI of ‘ The Understanding ’, where there are many delightful passages of special relevance to the ancient concepts about life. Again, he said that a bird, that ‘chooses with such care and nicety the place and materials of the nest, and sits upon her eggs for a due time, and in a suitable season, with all the precaution that a chymist is capable of in the most delicate projection, furnishes us with a lively instance of animal sagacity’. Locke, on the other hand, in his discussion of animal rationale, had refused to be drawn so far. ‘ And if Balaam’s ass had, all his life, discussed as rationally as he did once with his master, I doubt yet whether any one would have thought him worthy the name ‘man’, or allowed him to be of the same species with himself ’. Of these two statements Hume’s approximates more closely to the earliest Asiatic view of life, and it is on these lines that Messrs. Frankfort, Wilson, and Jacobsen have approached their problem, which, briefly put is-how did the early thinkers of the Near East come to say what they did about creation, the state, and man ? Professor and Mrs Frankfort define the earliest mode of thought as an ‘ I-thou ’ relation-ship, by which they mean that the primitive Asiatic conceived of all creation in a reciprocal nexus wherein the material world was percipient as well as perceived, and Professor Wilson elaborates the same theme by saying that for the Egyptians the world was consubstantial, and that their view of life might be defined as monophysite. Pro-fessor Jacobsen’s contribution illustrates to what extent the Mesopotamian view of life conformed with this outlook, for example how salt and grain were conceived of as animate beings in a close relationship with man, responsible and responsive to him. Other ideas peculiar to the Mesopotamian mind are no less clearly stressed, and herein lies the fascination of the book, that we have a comparative examination of the Egyptian, Mesopotamian and Israelite approach to life, for Hebrew theology was cast out of a similar matrix. In a concluding chapter by the Frankforts, we see the dawn of a new intellectual era. The Greek physical philosophers, regardless of the data of experience, carried the old basic concepts of the Egyptians and Mesopotamians from a concrete to an abstract frame and worked them to a reductio ad absurdurn, much as Hume did for the concepts of Cartesian philosophy. Their prescience gave birth to science. Nor should we forget that Thales of Miletus prophesied an eclipse, thereby following in the wake of the Babylonian astronomers, who had made similar observations and recorded them centuries earlier.

Health traditionally has been highly valued in many cultures, but it is only in the past century that science and technology have made possible the dramatic modification of the developmental potential of nations as well as individuals. That sickness and premature death are a major deterrent to the progress of a society has repeatedly been confirmed, most strikingly in the emerging nations. In such countries, alteration of a particular disease pattern by application of scientific knowledge has had immediate measurable effects upon the society as a whole. A prime example is the malaria eradication program, which has changed the productivity of large areas of the world.

The centennial of the Azusa Street revivals of 1906 provides us with convenient poles for charting shifts in the landscape of Christian spiritual healing practices during the past century. Alongside unprecedented achievements in medical science, nearly 80 percent of Americans report believing that God supernaturally heals people in answer to prayer. Individuals who need healing, even after trying the best medical cures, readily transgress ecclesiastical, physical, and social boundaries in their quest for health and wholeness. The promise of a tangible experience of divine power, moreover, presents an attractive alternative to seekers disillusioned with what they perceive as the callous materialism of medical science and the religious legalism of traditional Christian churches. This essay calls for new narratives of sacred space that map the ways that pentecostal and charismatic healing practices have proliferated, diversified, and sacralized a growing number and variety of physical, social, and linguistic spaces in the past hundred years. At the turn of the twentieth century, modernist epistemological assumptions that privileged reason over experience encouraged fine intellectual distinctions between the sacred and the secular. In esteeming bodily experience as more trustworthy than disembodied doctrine and in resisting linguistic binaries as culturally constructed, postmodern epistemologies have multiplied the number and range of places available to be endowed with sacred meanings. I argue that boundaries between the sacred and the secular are dissolving at the same time that new boundaries are being established, privileging particular places and defining a new relationship among the United States, the Americas, and the world.
