The fascinating world of lichens draws the attention of the researchers because of the numerous properties of lichens used traditionally and, in modern times, as a raw material for medicines and in the perfumery industry, for food and spices, for fodder, as dyes, and for other various purposes all over the world. However, lichens being widespread symbiotic entities between fungi and photosynthetic partners may acquire toxic features due to either the fungi, algae, or cyano-procaryotes producing toxins. By this way, several common lichens acquire toxic features. In this survey, recent data about the ecology, phytogenetics, and biology of some lichens with respect to the associated toxin-producing cyanoprokaryotes in different habitats around the world are discussed. Special attention is paid to the common toxins, called microcystin and nodularin, produced mainly by the Nostoc species. The effective application of a series of modern research methods to approach the issue of lichen toxicity as contributed by the cyanophotobiont partner is emphasized.

Wars in early modern times, although frequent, generated little price inflation because of their limited demands on real resources. The invention of paper currency and the resort to deficit financing to pay for wars changed that situation. In recent centuries wars have been the principal causes of inflation, although since World War II programs of social welfare unmatched by offsetting taxation have also fueled inflationary flames.

The mid-1990s through the first decade of the new millennium marked an increase in publications pertaining to war and violence in the ancient past. This review considers how scholars of the past decade have responded to that work. The emerging consensus is that war and violence were endemic to all societies studied by archaeologists, and yet the frequency, intensity, causes, and consequences of violence were highly variable for reasons that defy simplistic explanation. The general trend has been toward archaeologies of war and violence that focus on understanding the nuances of particular places and historical moments. Nevertheless, archaeologists continue to grapple with grand narratives of war, such as the proposition that violence has decreased from ancient to modern times and the role of war and violence in state formation and collapse. Recent research also draws attention to a more expansive definition of violence. Expected final online publication date for the Annual Review of Anthropology, Volume 50 is October 2021.

Climate change is of great importance in modern times and global warming is considered as a significant part of climate change. It is proved that human’s emissions such as greenhouse gases are one of the main sources of global warming (IPCC, 2018). Apart from greenhouse gases, there is another kind of matter being released in quantity via emissions from industries and transportations and playing an important role in global warming, which is aerosol. However, atmospheric aerosols have the net effect of cooling towards global warming. In this paper, climate change with respect to global warming is briefly introduced and the role of aerosols in the atmosphere is emphasized. Besides, properties of aerosols including dynamics and thermodynamics of aerosols as well as interactions with solar radiation are concluded. In the end, environmental policies and solutions are discussed. Keywords: Climate change, Global warming, Atmospheric aerosols, Particulate matter, Radiation, Environmental policy.

Abstract   Islam, religion of tolerance and love of peace is one of Habiburrahman El Shirazy’s, it is a study indicating the values ​​of love and tolerance of Islam in the modern public space area. This study used the underlying theory of the values ​​of love and tolerance as well as the role of Islam in modern times that has been developing in the public discourse that in the history of human civilization there are several things that must be understood that humans have the sense to differentiate between humans and other creatures. From this reason humans can do something to explore and explain things that are not known by others. The method that is used in data collection technique is documentation technique, because this study is descriptive qualitative. This study examines several things including the values of love and tolerance because accepting differences is a distinct pleasure for each particular societies in other words, not seeing other people as deviants or enemies but as partner to complement each other by having an equal position and equally valid and valuable as a way of managing life and living life both individually and collectively. Acceptance of differences demands changes in the legal rule in people's lives so that the role of religion in the modern public space area becomes a middle way to build diversity and a nature that must both appreciate and respect one another, this diversity is seen in the portrait of everyday life which then creates peace, and harmony in interacting with all elements of society.

The concept of e-governance in the modern times refocuses on the fundamental role of government as the institution of transformation of society. To understand the intricacies of e- governance it will be pertinent to examine the concept from an ecological perspective. The system of governance in order to meet the challenges must equip itself with the mechanisms of managing the pressures generated from different subsystems. The interrelationship and interdependence of these subsystems explain the operational reality of bureaucratic systems in relation to societal transformation. In last few decades, the history of humankind has seen the enormous growth of technology and its utilization for creating a better global society, by disseminating the knowledge down to common person and transcending the geographical boundaries. The accessibility of knowledge is not confined to any nation. Thus, the whole world has to acquire a bigger vision of coexistence with divergent societal patterns in future, because it is the source of developing shared visions. The present analysis focuses on the normative aspects of e-connectivity, specifically, 1. It proposes a conceptual framework to understand the futuristic operational dynamics of ecology of e-governance; 2. It proposes how the interactions of various components of e-governance, can help in evolving a universal society with ethical axis to create a better world; 3. It suggests that the whole world eventually has to move in the direction of evolving a global society by inculcating universal values of coexistence with divergent ethos. Hence, the need to transform the society cannot be subdued; and 4. It focuses on striving a balance between technological and human aspects by bringing out philosophical core at the centre to evolve global society.

This paper traces the significant role of Sufism in promoting Muslim—Christian dialogue at a time of growing friction and colonial encroachment. The widening gap in power and wealth between the Western and Muslim world from the 19th century onward heightened cultural animosity between the two but also evoked ecumenical efforts to diffuse this contention. One such effort was Islamic modernism, which promoted a liberal interpretation of scripture and advocated the establishment of an inclusive polity that would encompass women and religious minorities. Islamic modernism gained considerable attention in the research literature. By contrast, another important ecumenical discourse, based on Sufism, which emerged in the early 20th century and was joined by Muslims and European Christians alike, has remained largely unexplored in the literature. Cairo, Rome, and Paris constituted the geographical points of convergence of this discourse; the Sufi teachings of Ibn al-ءArabi (d. 1240) provided its ideological core. Most participants sought to position Sufi values as a cultural bridge between East and West, although political considerations were also involved. This paper shows that far from being anachronistic or detached from reality, as some of its vociferous critics charged, Sufism remained a vital tradition well into modern times. Moreover, it engendered a lively debate within Western intellectual circles over the role of spirituality in modern life.

Those who view Rome from the perspective of modern empires have been struck by Rome's longevity (for example, Brunt 1965:267; Doyle 1986:81–103; Syme 1958:1). Attempts to explain this phenomenon, however, have given little if any consideration to why movements of national independence have occurred in modern times, but not in Roman antiquity. This is the more striking inasmuch as nationalist rebellions against imperial rule typically accompanied the dissolution of direct imperial control over native populations during the nineteenth and twentieth centuries. Certainly the decisions of modern imperialists to give up their empires have been influenced by political idealism or by calculations of economic self-interest unique to their historical situations (Liithy 1964:34). Nonetheless, the role of their subjects must also be taken into consideration, because it was the initiative of the colonial natives, not that of the imperial masters, that typically has resulted in the first calls for independence and, most often, in the nationalist rebellions that provoked imperialists into dismantling their empires. Idealistic impulses and calculations of economic self-interest alike have taken place within the context of that initiative and cannot help but to have been colored by it. It would be a mistake to identify nationalist sentiment and rebellion as the only reasons for the collapse of modern empires, but they must be included among the decisive reasons.
