AbstractHerein, a novel nanobiocomposite scaffold based on modifying synthesized cross-linked terephthaloyl thiourea-chitosan hydrogel (CTT-CS hydrogel) substrate using the extracted silk fibroin (SF) biopolymer and prepared Mg(OH)2 nanoparticles was designed and synthesized. The biological capacity of this nanobiocomposite scaffold was evaluated by cell viability method, red blood cells hemolytic and anti-biofilm assays. According to the obtained results from 3 and 7 days, the cell viability of CTT-CS/SF/Mg(OH)2 nanobiocomposite scaffold was accompanied by a considerable increment from 62.5 to 89.6% respectively. Furthermore, its low hemolytic effect (4.5%), and as well, the high anti-biofilm activity and prevention of the P. aeruginosa biofilm formation confirmed its promising hemocompatibility and antibacterial activity. Apart from the cell viability, blood biocompatibility, and antibacterial activity of CTT-CS/SF/Mg(OH)2 nanobiocomposite scaffold, its structural features were characterized using spectral and analytical techniques (FT-IR, EDX, FE-SEM and TG). As well as, given the mechanical tests, it was indicated that the addition of SF and Mg(OH)2 nanoparticles to the CTT-CS hydrogel could improve its compressive strength from 65.42 to 649.56 kPa.

Secular Spirituality

This paper examines the nature of spirit and spirituality as organic response to threat in the context of a global pandemic. Drawing from the fields of neuroscience, philosophy and theology, the author defines spirit as the biological capacity of a living organism to maintain homeostasis in response to changes in its environment. The capacity of individual human organisms to respond to changes that are perceived as threats to homeostasis with passive and active power is posited as a spirituality that is crucial for the survival of the human species. The paper represents a form of secular spirituality that is synonymous with the natural power of organic life.

Because bioeconomics is born of the interaction between the biological activity system and its socio-economic activity system, a holistic methodological approach is essential to study the relations between them. However, it must search for increasing levels of reductionism within each discipline to delve into the ultimate nature of each one of the intervening forces, whether economic or biological. This paper explores the economic forces. Through the biological capacity to comprehend, man and by extension, society, accumulates knowledge, the fulcrum from which he is able to dominate over his natural habitat. From this ‘point d’appui’, man builds two basic tools to assist him in achieving the goal of bettering his social condition. On the one hand, he creates institutions that allow him to “live with others” and, on the other, he develops technology that helps him to “live better with others”. Institutions, also referred to as ‘social technology’, tend toward stability over time while technology or ‘material technology’, tends toward instability, which would suggest that, normally, the mechanics of change will originate in material technology and, from there, progress to social technology by way of the political market. The level of progress and development attained depends on the quantity and rate of growth of knowledge applied by a society. In the process, man and his collectivity are forced to adopt new views of their environment through new shared mental models. The concurrence of equipment and political market will ultimately become the prime mover of institutional and economic change as well as change in mentality. Both technologies must keep on an adaptive course of stable evolution since discrepancies arising between them can cause tension between the various social groups. Adequate management of technological shock is essential to avoid extreme situations of social conflict. Herein lie the most important political decisions that a government must confront over the long term.

Actual Participation

In the current era of electronic domination of human experience, be it via cell phone and/or computer addiction, or the ubiquitous television, actual participation in music- making is less and less common for the average person, child or adult. Passive participation through listening is most often cited by people as their major experience with music in their lives. When asked if listening has therapeutic effects, it is rare for anyone to respond in the negative. Likewise, for performers/active participants in music- making, be it solitary or as part of a group, invariably an enhanced sense of well-being from the act of making music is reported.This paper addresses therapeutic aspects of musical participation (singing, clapping, playing an instrument, dancing, listening) by providing a historical overview (12th c to present) of attitudes toward music’s therapeutic effects. It argues that music exists through the interaction of our biological capacity to make music with our cultural circumstances. How individuals benefit in all aspects their being – physical, mental and emotional – from engaging in the act of making music is illustrated with examples from field research in southern Africa. Finally implications for Music Education are explored which emphasize how more comprehensive integration of music into the curriculum can serve as an antidote to the increasing isolation and alienation of modern life.

Target Plant

Reforestation and restoration using nursery-produced seedlings is often the most reliable way to ensure successful establishment and rapid growth of native plants. Plant establishment success—that is, the ability for the plant to develop within a set period of time with minimal further interventions needed—depends greatly on decisions made prior to planting, and yet nursery-grown plants are often produced independently of considering the range of stressors encountered after nursery production. The optimal plant or seedling will vary greatly with species and site (depending on edaphic and environmental conditions), and in having the biological capacity to withstand human and wildlife pressures placed upon vegetative communities. However, when nursery production strategies incorporate knowledge of genetic variability, address limiting factors, and include potential mitigating measures, meeting the objectives of the planting project—be it reforestation or restoration—becomes more likely. The Target Plant Concept (TPC) is an effective framework for defining, producing, and handling seedlings and other types of plant material based on specific characteristics suited to a given site. These characteristics are often scientifically derived from testing factors that are linked to outplanting success, such as seedling morphology and physiology, genetic source, and capacity to overcome limiting factors on outplanting sites. This article briefly summarizes the current knowledge drawn from existing literature for each component of the TPC framework, thereby helping land managers and scientists to meet objectives and accelerate reforestation and restoration trajectories.

The term “resilience” originated in environmental studies and describes the biological capacity to adapt and thrive under adverse environmental conditions. Regional economic resilience is defined as the capacity of a territory’s economy to resist and/or recover quickly from external shocks, even improving its situation from the pre-shock status. This editorial introduction provides a summary of the eleven contributions included in the special issue on regions and economic resilience. These eleven articles focus on different channels related to processes of mitigation (resistance-recovery) and adaptive resilience (reorientation-renewal) in a wide variety of geographical settings and scales. They include methodological advances and also relevant results from a policy perspective. The editorial concludes by providing some directions for future research.

Sustainability is the possibility of all people living rewarding lives within the means of nature. Despite ample recognition of the importance of achieving sustainable development, exemplified by the Rio Declaration of 1992 and the United Nations Millennium Development Goals, the global economy fails to meet the most fundamental minimum condition for sustainability—that human demand for ecosystem goods and services remains within the biosphere's total capacity. In 2002, humanity operated in a state of overshoot, demanding over 20% more biological capacity than the Earth's ecosystems could regenerate in that year. Using the Ecological Footprint as an accounting tool, we propose and discuss three possible global scenarios for the future of human demand and ecosystem supply. Bringing humanity out of overshoot and onto a potentially sustainable path will require managing the consumption of food, fibre and energy, and maintaining or increasing the productivity of natural and agricultural ecosystems.
