The Scientific Basis of the Target Plant Concept: An Overview

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.

Mapping National Environmental Sustainability Distribution by Ecological Footprint: The Case of Italy

The paper proposes a possible way of spatially representing sustainability in Italy. For this purpose, the ecological footprint approach was used as a methodological framework to assess the level of sustainability of the 8092 Italian municipalities. For each municipality, the exploitation of ecosystem services, assessed by the ecological footprint indicator, and the corresponding availability of biological capacity, associated to an indicator, have been calculated and compared, thus generating a map representing the relative sustainability of Italian municipalities. The results show a very scattered distribution of ecological balance, wherein unsustainable conditions characterize more than 60% of the territory and almost 95% of the Italian population. Despite the limitations of the methodology and some assumptions regarding the ecological footprint assessment at the municipality level, the study represents an attempt to produce an innovating tool that, based on an operational definition of sustainability, can represent natural resource exploitation at the local level, and provide useful information to address coherent and targeted environmental policies of sustainability.

Self and Dignity: The Spirituality of Survival

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.

Deception, Lying, and Lust

Primatologists have identified the apparent ability to deceive others in more dominant positions in order to gain sexual or other privileges. Evidence for the deliberative quality of deception in primates is much harder to assess. This chapter explores the biological capacity to deceive and shows how common it is among social animals even though relationships involving honest signalling are usually dominant. The chapter investigates the potential evolutionary roles for deception and how it plays out in the human sphere at different societal levels. Lying, however, which relies on language, brings in aspects to deception which are unique to our species. The human capacity for complex symbolic thought in which language emerges also influences the biocultural evolution of language and associated capacity for lying. Theological ethical debates about whether Thomas Aquinas ever permitted lying in situations where greater harm would ensue are worth considering in the light of the biological advantages of deception. Lust (illicit sexual desire) is another of the seven deadly sins and has been given perhaps greater pride of place in the Christian tradition because of a common interpretation of Augustine linking sex with original sin.

EU Political Agenda of COVID-19 Crisis: Mechanisms and Financial Instruments to Mitigate the Economic Effects of the Pandemic in Newspapers ‘El País’ and ‘El Mundo’

With approximately one fifth of the world population in blockade, the COVID-19 has radically changed indi­viduals’ way of life. The virus has in­fected million people and more than 200 countries (Worldometer’s COV­ID-19 data). But the effects of the virus go far beyond its biological capacity to cause disease. Beginning in the city of Wuhan, China, it rapidly spread across national borders, and has drawn at­tention to the porous and interconnect­ed world in which we live. The econom­ic results from the lockdown measures put the question of the European Un­ion project. This article intends to an­alyse how the press in Spain, one of the Eurozone countries most affected by COVID-19, reflected the decisions of the EU (mechanisms and financial instruments) to mitigate the economic effects. The corpus of analysis includes articles published by the newspapers ‘El País’ and ‘El Mundo’. The analytic peri­od starts on March 1 and ends on April 24, the day after the European Council approved the Economic Recovery Fund. The results show that the published news reflects the recommendations and decisions of the EU institutions, framing the mechanisms and financial instruments into coordinated Econom­ic Strategy from EU, so essential to the economic recovery of Member States. Keywords: European Union, COV­ID-19, political agenda, Spanish news­paper, content analysis.

Chitosan hydrogel/silk fibroin/Mg(OH)2 nanobiocomposite as a novel scaffold with antimicrobial activity and improved mechanical properties

Herein, 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.

Hip preservation surgery and the acetabular fossa

As our understanding of hip function and disease improves, it is evident that the acetabular fossa has received little attention, despite it comprising over half of the acetabulum’s surface area and showing the first signs of degeneration. The fossa’s function is expected to be more than augmenting static stability with the ligamentum teres and being a templating landmark in arthroplasty. Indeed, the fossa, which is almost mature at 16 weeks of intrauterine development, plays a key role in hip development, enabling its nutrition through vascularization and synovial fluid, as well as the influx of chondrogenic stem/progenitor cells that build articular cartilage. The pulvinar, a fibrofatty tissue in the fossa, has the same developmental origin as the synovium and articular cartilage and is a biologically active area. Its unique anatomy allows for homogeneous distribution of the axial loads into the joint. It is composed of intra-articular adipose tissue (IAAT), which has adipocytes, fibroblasts, leucocytes, and abundant mast cells, which participate in the inflammatory cascade after an insult to the joint. Hence, the fossa and pulvinar should be considered in decision-making and surgical outcomes in hip preservation surgery, not only for their size, shape, and extent, but also for their biological capacity as a source of cytokines, immune cells, and chondrogenic stem cells.

Judgment, normativity and the subject

One of the fundamental questions in post-Fregean philosophy is how to account for the normativity involved in assertoric claims once the traditional subject-object view of thinking is rejected. One of the more productive lines of inquiry in the contemporary literature attributes normativity to second nature, which is presented as a sui generis space of reason giving and receiving distinct from the space of nature studied by the natural sciences. In this paper I suggest an alternative account by drawing from Castoriadis’s philosophical interpretation of autopoiesis. For Castoriadis, the idea of second nature protects the modern conception of nature from undergoing the radical critique it requires, for it restricts normativity to the anthropic sphere. In contrast, he proposes an autopoietic account of the subject that grounds the capacity to know that one knows in the activity of the living being. Castoriadis demonstrates that the normativity of assertoric claims is not a vertical break from nature but rather a horizontal transformation of the biological capacity for self-referentiality.
