Academic literature on the topic 'CSR adaptive plant strategie'

Sulfur is an essential macronutrient for plant primary metabolism. Its availability can modulate plant growth in most terrestrial ecosystems. However, its relationship with other leaf and nutrient traits, and hence its contribution to plant functioning, remains unclear. We analysed leaf and nutrient traits for 740 vascular plant species growing in a wide range of environmental conditions in Northern Italy. We determined whether leaf sulfur content per unit leaf dry mass (LSC) is associated with leaf economics spectrum, and whether its distribution among functional types (growth forms, leaf life span categories, and Grime’s CSR (Competitive, Stress-tolerant, Ruderal strategies) could help to elucidate adaptive differences within plant taxa. High LSC values were mainly associated with fast-growing species representative of R- and C- strategy selection, thus the acquisitive extreme of plant economics, reflecting strong potential connections with ecosystem properties such as biomass production or litter decomposability. In general, LSC was significantly and positively correlated with leaf nitrogen content, and nitrogen to sulfur ratio was constant throughout growth forms, leaf life span and CSR strategies, and phylogenetic effects were evident. Our findings highlight that LSC variation is strongly associated with the leaf economics spectrum, suggesting that additional nutrients seldom included in functional analyses may also be embroiled within the context of plant economics. However, different ratios among nitrogen and sulfur may be expected across different plant families, suggesting that deeper insight from functional groups can provide a bridge between plant stoichiometry and ecology, useful for the evaluation of ecological responses to global change.

Human Natural Killer (NK) cells are all round players in immunity thanks to their powerful and immediate response against transformed cells and the ability to modulate the subsequent adaptive immune response. The potential of immunotherapies based on NK cell involvement has been initially revealed in the hematological setting but has inspired the design of different immune tools to also be applied against solid tumors, including colorectal cancer (CRC). Indeed, despite cancer prevention screening plans, surgery, and chemotherapy strategies, CRC is one of the most widespread cancers and with the highest mortality rate. Therefore, further efficient and complementary immune-based therapies are in urgent need. In this review, we gathered the most recent advances in NK cell-based immunotherapies aimed at fighting CRC, in particular, the use of monoclonal antibodies targeting tumor-associated antigens (TAAs), immune checkpoint blockade, and adoptive NK cell therapy, including NK cells modified with chimeric antigen receptor (CAR-NK).

Successfully restoring degraded forest areas depends on seedlings adapting their growth to suit harsh environments. Hence, the requirements for seedlings’ growth need to be addressed before replanting degraded sites. The present study determines the effect of abiotic factors viz. light irradiance (8%, 30%, and 100%), nutrient addition (no fertiliser (NF), NPK, and vermicompost) on the growth performance and photosynthetic capacity of two dipterocarp species seedlings, Shorea leprosula Miq. and Shorea acuminata Dyer. The morphological characteristics assessed for growth performance comprised plant height, stem diameter, leaf count, leaf area, relative chlorophyll concentration, biomass, and root-to-shoot ratio. Li-Cor 6400 and 6800 were used to measure the leaf gas exchange traits, including photosynthetic rate (A), transpiration rate (E), intercellular CO2 concentration (Ci), stomatal conductance (gsw), and water-use efficiency (WUE). Our results demonstrated that different levels of light intensity and nutrient amendment significantly impacted plant-growth performance. Plants grown in 30% irradiance showed better growth performance in terms of relative height growth rate (RHGR), mean number of leaves, and leaf areas 41%, 24%, and 32% higher than the control. The A value was also higher in 30% irradiance, but no significant differences were observed between each level of light irradiance. The addition of vermicompost gave better growth for RHGR, relative diameter growth rate (RDGR), mean number of leaves, biomass, and relative chlorophyll concentrations 47%, 40%, 131%, 19%, and 27% higher than the control, respectively. However, the results obtained for photosynthetic parameters were contrary to growth performance. The photosynthesis rate (A) was higher (14.8%) in NPK compared to the control, and the other photosynthetic parameters did not differ significantly despite different nutrient amendments. In terms of species, S. leprosula has better growth performance and photosynthetic characteristics than S. acuminata in different light irradiance and nutrient amendments, thereby rendering S. leprosula the preferred rehabilitation species. Generally, nutrient addition of either NPK or vermicompost and 30% light irradiance gave better morphological and physiological growth for both species. The outcome of this study could provide a better understanding on the forest rehabilitation strategy to reduce the seedling-mortality rate, particularly for climax tree species.

This study aimed to analyze the correlation between Human Capital Sustainability Leadership style and manager resilience through a pragmatic worldview. Using explanatory sequential mixed methods research design (QUAN→qual), respondents covered were managers from the Airline Operations Group of an AIRLINE Company with at least one year of managerial experience within the organization. In the quantitative phase, Human Capital Sustainability Leadership Scale by Di Fabio and Peiro (2018) and Domain-Specific Resilient Systems Scales (DRSSWork) by Maltby, Day, Hall, and Chivers (2019) were used for the online survey. Forty-five (45) eligible respondents have participated. Mean, standard deviation, and Spearman rank correlation coefficient were employed. To further explain the quantitative results, one-on-one qualitative interviews were done with eight (8) key informants, face-toface and online. Themes were identified. Results showed that Human Capital Sustainability Leadership style was exhibited by the Airline Operations Group managers to a very high degree while resilience was exhibited to a high degree. There was a linear, positive, and highly significant correlation between Human Capital Sustainability Leadership style and resilience. Each aspect of the Human Capital Sustainability Leadership style was positively, highly, and significantly correlated with manager resilience. Through triangulation, a model of leadership styles and manager resiliency was built. To implement the model, implications for a management development program were identified.ReferencesAcosta, H., Cruz-Ortiz, V., Salanova, M., & Llorens S. (2015).

Membrane lipid reprogramming is one of the most important adaptive strategies in plant species under unfavorable environmental circumstances. Therefore, the present experiment was conducted to elucidate the effect of diethyl aminoethyl hexanoate (DA-6), a novel synthetic plant growth regulator, on oxidative damage, photosynthetic performance, changes in lipidomic profile, and unsaturation index of lipids in two white clover (Trifolium repens) cultivars (drought-sensitive “Ladino” and drought-resistant “Riverdel”) under PEG-6000-induced water-deficit stress. Results revealed that water-deficit stress significantly enhanced oxidative damage and decreased photosynthetic functions in both cultivars. However, the damage was less in Riverdel. In addition, water-deficit stress significantly decreased the relative content of monogalactocyl-diacylglycerols (MGDG), sulfoquinovosyl-diacylglycerols (SQDG), phosphatidic acisd (PA), phosphatidyl-ethanolamines (PE), phosphatidyl-glycerols (PG), phosphatidyl-serines (PS), ceramides (Cer), hexosylmonoceramides (Hex1Cer), sphingomyelins (SM), and sphingosines (Sph) in both cultivars, but a more pronounced decline was observed in Ladino. Exogenous application of DA-6 significantly increased the relative content of digalactocyl-diacylglycerols (DGDG), monogalactocyl-diacylglycerolsabstra (MGDG), sulfoquinovosyl-diacylglycerols (SQDG), phosphatidic acids (PA), phosphatidyl-ethanolamines (PE), phosphatidyl-glycerols (PG), phosphatidyl-inositols (PI), phosphatidyl-serines (PS), ceramides (Cer), hexosylmonoceramides (Hex1Cer), neutral glycosphingolipids (CerG2GNAc1), and sphingosines (Sph) in the two cultivars under water-deficit stress. DA-6-treated Riverdel exhibited a significantly higher DGDG:MGDG ratio and relative content of sphingomyelins (SM) than untreated plants in response to water deficiency. Furthermore, the DA-6-pretreated plants increased the unsaturation index of phosphatidic acids (PA) and phosphatidylinositols (PI) in Ladino, ceramides (Cer) and hexosylmonoceramides (Hex1Cer) in Riverdel, and sulfoquinovosyl-diacylglycerols (SQDG) in both cultivars under water stress. These results suggested that DA-6 regulated drought resistance in white clover could be associated with increased lipid content and reprogramming, higher DGDG:MGDG ratio, and improved unsaturation index of lipids, contributing to enhanced membrane stability, integrity, fluidity, and downstream signaling transduction.

Ecological strategy is the tactics employed by species in adapting to abiotic and biotic conditions. The ecological strategy spectrum is defined as the relative proportion of species in different ecological strategy types within a community. Determinants of ecological strategy spectrum of plant community explored by most previous studies are about abiotic factors. Yet, the roles of biotic factors in driving variations of ecological strategy spectra of forest communities across different geographic regions remains unknown. In this study, we established 200 0.04-ha forest dynamics plots (FDPs) and measured three-leaf functional traits of tree and shrub species in four forest vegetation types across four climatic zones. Based on Grime’s competitor, stress-tolerator, ruderal (CSR) triangular framework, and the StrateFy method, we categorized species into four ecological strategy groups (i.e., C-, S-, Int-, and R-groups) and related the ecological spectra of the forests to three species diversity indices [i.e., species richness, Shannon-Wiener index, and stem density (stem abundance)]. Linear regression, redundancy analysis, and variance partition analysis were utilized for assessing the roles of species diversity in regulating ecological strategy spectra of forest communities across different climatic zones. We found that the proportion of species in the C- and Int-groups increased, while the proportion of species in the S-group decreased, with the increase of three indices of species diversity. Among the three species diversity indices, stem abundance played the most important role in driving variations in ecological strategy spectra of forests across different climatic zones. Our finding highlights the necessity of accounting for biotic factors, especially stem abundance, in modeling or predicting the geographical distributions of plant species with varied ecological adaptation strategies to future environmental changes.

Abstract Collaboration is increasingly emphasized as a tool to realize national-level policy goals in public lands management. Yet, collaborative governance regimes (CGRs) are nested within traditional bureaucracies and are affected by internal and external disruptions. The extent to which CGRs adapt and remain resilient to these disruptions remains under-explored. Here, we distill insights from an assessment of the Collaborative Forest Landscape Restoration Program (CFLRP) projects and other CGRs. We asked (1) how do CGRs adapt to disruptions? and (2) what barriers constrained CGR resilience? Our analysis is informed by a synthesis of the literature, case examples and exemplars from focus groups, and a national CFLRP survey. CGRs demonstrated the ability to mobilize social capital, learning, resources, and flexibility to respond to disruptions. Yet authority, accountability, and capacity complicated collaborative resilience. We conclude with policy and practice recommendations to cultivate collaborative resilience moving forward. Study Implications Collaborative approaches between public lands management agencies and nongovernment organizations have become common in forest restoration. Yet collaborative progress may be affected by turnover, wildfire disturbances, or legal or policy changes. We assessed how forest collaboratives in the United States adapted to changes that affected their performance and documented the factors that constrained response. We found that forest collaboratives developed myriad strategies to adapt to these changes, although limited authority, capacity, and accountability constrain adaptation options. We offer policy and practice recommendations to overcome these constraints, increase adaptation options, and enhance the sustainability of forest collaboratives.

Surface water and groundwater catchments rarely align with the boundaries of cities, states, or nations. More often, water runs through, over, and under man-made sociopolitical divisions, making the governance of transboundary waters a formidable task. Although much of the public conversation regarding the availability and management of shared waters may appear to be dire (e.g., reports of “water wars”), there are transboundary basin water management strategies across the globe which offer hope. These include the efforts of the Apalachicola-Chattahoochee-Flint Stakeholders (ACFS) in the southeastern United States, which may serve as a useful template for future conversations around the water sharing table. The Apalachicola-Chattahoochee-Flint Basin (ACF Basin) is a vital economic engine in the southeastern United States. The waters of the ACF are shared between three states—Alabama, Florida, and Georgia—and harbor some of the richest freshwater biodiversity in North America, including sturgeon, rock bass, madtom, sculpin, bass, darters, and the highest densities of freshwater mussels in the world. Many of these are species of concern or threatened or endangered species; therefore, water management strategies in multiple portions of the ACF must comply with habitat protection plans under the U.S. Environmental Protection Act of 1970 (https://www.enr.gov.nt.ca/en/environmental-protection-act). The ACFS was organized in 2009 in the hopes of overcoming a decades-long stalemate between Alabama, Florida, and Georgia, regarding the use of shared waters in the ACF Basin. Despite years of litigious relationships among these three states, the ACFS managed to bring a diverse and previously contentious set of water users to the table and build consensus on a shared water management plan for the entire ACF Basin. While the ACFS holds no regulatory power, they made more progress in breaking through existing distrust and deadlock than any previous efforts in this basin to date. In the end, they developed cooperation, respect, and a sustainable and adaptive water management plan which included input and buy-in from all identified water sectors in the ACF Basin. It is, therefore, a valuable exercise to examine the ACFS model and contemplate whether it contains exportable methodologies for other catchments challenged with managing transboundary waters.

Climate is, presently, a heatedly discussed topic. Concerns about the environmental, economic, political and social consequences of climate change are of central interest in academic and popular debates. As such, climate change is a ‘hot’ cultural discourse and media issue. Moreover, there has recently been a ‘cultural turn’ in climate change science and politics, with some scholars arguing that climate change research and action has been hindered because it has not fully accommodated cultural values that give everyday meaning to climate, and consequently urging for greater attention to the cultural dimensions of climate change. As Mike Hulme asserts, “registers of climate can be read in memory, behaviour, text and identity as much as they can be measured through meteorology” (7) and thus “the idea of climate can only be understood when its physical dimensions are allowed to be interpreted by their cultural meanings” (6) (for specifically Australian examples, see Sherratt, Griffiths and Robin; Nicholls). Climate change is both a “physical transformation and cultural object” and requires new examination which “needs to start with contributions from the interpretative humanities and social sciences” (Hulme 5). Advancing these debates, this issue of M/C Journal adds to the critical interface of climate and culture, particularly in the context of climate change. A number of key themes concerning the culture-climate nexus weave through the following papers. Most notably, the authors consider how climate and climate change are embodied and experienced at local and personal levels. Dominant earth systems approaches to climate have enumerated—rather than ‘felt’—local changes in precipitation and temperature, fixing these statistics to planetary models of global warming and thus cleaving changes in weather patterns from their localised cultural meanings and constitutive values (Hulme). Instead, a cultural approach emphasises that individuals ‘feel’ their environments through ‘embodied’ engagements with seasonal weather conditions (Palang et al; Ingold). Statistics cannot capture how these everyday visceral and emotional experiences will be altered by climate change. All the papers in this collection invoke felt, embodied responses to changing climatic conditions, from housing (Simpson), eating (Brien) and transport (Simpson), to disaster (Wolbring) and mitigation (Harrison) responses, to the very biopolitics of life (Potter). Likewise, the authors in this collection indicate that anthropogenic climate change results from uneven, localised consumption. As commentators have noted, planetary statistics on global warming also cleave its ‘causes’ from local resource over-use, removing the ‘problem’ from the scope of everyday lifeworlds. Yet, just as climate change impacts will be felt locally, mitigation or adaptation must start with localised individual and collective responses. This might mean changing foodways (Brien), architecture (Sully), car use (Simpson) or energy consumption and its means of calculation (Potter). Simultaneously, these localised responses feed into wider global environmental governance attempts to address mitigation (Harrison) and adaptation (Wolbring). To this end, another critical contribution that cultural and media studies makes to this ‘wicked problem’ concerns communication strategies about climate change impacts, mitigation and adaptation. Communication is the central theme of Harrison’s paper, and is also addressed by other authors here (e.g. Wolbring, Potter and Simpson). Our lead paper, by Emily Potter, provides a timely provocation on climate change as a ‘biopolitical terrain’, where ‘the politics of life’ undergird the debates unfolding across and between state, corporate and domestic spheres. She seeks to complicate moralistic discussions of ‘good’ and ‘bad’ environmental practices that have emerged in the wake of climate change concerns. Instead, Potter prompts us to recognise that the spectrum of investments by actors, interests and devices, across a range of spheres, is fundamentally focused on sustaining life. Life-sustaining practices and debates consequently weave through the subsequent papers. Indeed, the following two papers are very much concerned with different ways of sustaining life, and how these practices are entwined with changing lifestyles. Donna Lee Brien’s paper focuses on foodways. She notes that eating is both a biological and cultural activity, and takes this interplay a step further by exploring how practices of eating are also bound up with environmental changes. Brien argues that awareness of climate change is prompting (r)evolutionary modifications in popular foodways, such as the Slow Food movement. She suggests, moreover, that further changes might be driven by increased insight into the connections between climate change and the social injustices of food production. Catherine Simpson focuses on another key dimension of Western lifestyles: automobility. ‘Automobile dependence’ is a major challenge for climate change mitigation and adaptation. In response, Simpson considers how cars might be used differently, analysing the developing phenomenon of car sharing, with specific reference to its emergence in Sydney. She argues that car sharing is an ‘adaptive technology’ that both extends and subverts the flexibility and autonomy associated with automobility. Car sharing organisations and practices transform car cultures: instead of privately-owned and stridently consumerist vehicles, ‘philandering car sharers’ invest in different subjectivities and values. Nicole Sully tackles climate-culture connections broadly, rather than modifications in the wake of climate change. Her focus is houses designed by seminal figures in Modern Architecture, and she discusses a number of pragmatic examples where climatic conditions became a contested issue in the reception of ‘the masterpiece’. In doing so, Sully shows the intimate links between dwelling and climate, and that effective building must account for weather and climatic patterns. She notes that these connections will be an increasing concern in the context of climate change, prompting greater attention to sustainable housing. Gregor Wolbring takes a different tack: he is concerned with the plight of disabled people in the context of climate change. He argues that disabled people are disproportionately affected by natural disasters—such as those sometimes linked with climate change—but points out that climate discourse rarely accounts for disabled people. Wolbring contends that more needs to be done to integrate disabled people into climate change plans to avoid ‘adaptation apartheid’. At the same time, he notes that disabled people could contribute to adaptation strategies through their experiences of interdependence and resilience. In the final paper, Karey Harrison focuses on communication about climate change and mitigation. She draws on her experience as a Climate Presenter in The Climate Project and wider theories of marketing and behavioural change. Harrison considers the usefulness of marketing approaches for prompting individual behavioural change, and how they work effectively alongside strategies that encourage transformations in wider business and social systems. She demonstrates that effective communication about climate change impacts and practices of mitigation is vital if we are to approach this ‘wicked problem’ with open eyes. Together, these papers provide new reflections on the climate-culture nexus, especially in the light of climate change threats. Our cultures—lifestyles, habits, rhythms, practices—are bound up with climatic conditions. But our cultures will have to change in the wake of anthropogenic climate change. Everyday practices—of eating, driving and housing, for instance—will have to change in scenarios of either mitigation or adaptation. If we want to arrest climate change, we have to change our lifestyles. And if climate change can’t be mitigated, adaptation will also require lifestyle changes. Existing embodied connections to local environments and weather patterns will take new forms. The cover picture for this issue provides an example of possible changes in the weather.

Every crisis at the same time reveals, forewarns and implies changes with cyclical trends that can be analyzed from different disciplinary perspectives, building scenarios to anticipate the future, despite uncertainties and risks. And the current crisis certainly appears as one of the most problematic of the modern era: recently, Luigi Ferrara, Director of the School of Design at the George Brown College in Toronto and of the connected Institute without Boundaries, highlighted how the pandemic has simply accelerated undergoing dynamics, exacerbating other crises – climatic, environmental, social, economic – which had already been going on for a long time both locally and globally. In the most economically developed contexts, from North America to Europe, the Covid emergency has led, for example, to the closure of almost 30% of the retail trade, as well as to the disposal and sale of many churches. Places of care and assistance, such as hospitals and elderly houses, have become places of death and isolation for over a year, or have been closed. At the same time, the pandemic has imposed the revolution of the remote working and education, which was heralded – without much success – more than twenty years ago. In these even contradictory dynamics, Ferrara sees many possibilities: new roles for stronger and more capable public institutions as well as the opportunity to rethink and redesign the built environment and the landscape. Last but not least, against a future that could be configured as dystopian, a unique chance to enable forms of citizenship and communities capable of inhabiting more sustainable, intelligent and ethical cities and territories; and architects capable of designing them. This multifactorial and pervasive crisis seems therefore to impose a deep review of the current unequal development models, in the perspective of that “creative destruction” that Schumpeter placed at the basis of the dynamic entrepreneurial push: «To produce means to combine materials and forces within our reach. To produce other things, or the same things by a different method, means to combine these materials and forces differently» (Schumpeter, 1912). A concept well suiting to the design practice as a response to social needs and improving the living conditions. This is the perspective of Architectural Technology, in its various forms, which has always placed the experimental method at the center of its action. As Eduardo Vittoria already pointed out: «The specific contribution of the technological project to the development of an industrial culture is aimed at balancing the emotional-aesthetic data of the design with the technical-productive data of the industry. Design becomes a place of convergence of ideas and skills related to factuality, based on a multidisciplinary intelligence» (Vittoria, 1999). A lucid and appropriate critique of the many formalistic emphases that have invested contemporary architecture. In the most acute phases of the pandemic, the radical nature of this polycrisis has been repeatedly invoked as a lever for an equally radical modification of the development models, for the definitive defeat of conjunctural and emergency modes of action. With particular reference to the Italian context, however, it seems improper to talk about a “change of models” – whether economic, social, productive or programming, rather than technological innovation – since in the national reality the models and reference systems prove to not to be actually structured. The current socio-economic and productive framework, and the political and planning actions themselves, are rather a variegated and disordered set of consolidated practices, habits often distorted when not deleterious, that correspond to stratified regulatory apparatuses, which are inconsistent and often ineffective. It is even more difficult to talk about programmatic rationality models in the specific sector of construction and built environment transformation, where the enunciation of objectives and the prospection of planning actions rarely achieve adequate projects and certain implementation processes, verified for the consistency of the results obtained and monitored for the ability in maintaining the required performance over time. Rather than “changing the model”, in the Italian case, we should therefore talk about giving shape and implementation to an organic and rational system of multilevel and inter-sectorial governance models, which assumes the principles of subsidiarity, administrative decentralization, inter-institutional and public-private cooperation. But, even in the current situation, with the pandemic not yet over, we are already experiencing a sort of “return to order”: after having envisaged radical changes – new urban models environmentally and climatically more sustainable, residential systems and public spaces more responsive to the pressing needs of social demand, priority actions to redevelop the suburbs and to strength infrastructures and ecosystem services, new advanced forms of decision-making decentralization for the co-planning of urban and territorial transformations, and so on – everything seems to has been reset to zero. This is evident from the list of actions and projects proposed by the National Recovery and Resilience Plan (NRRP), where no clear national strategy for green transition emerges, even though it is repeatedly mentioned. As highlighted by the Coordination of Technical-Scientific Associations for the Environment and Landscape1, and as required by EU guidelines2, this transition requires a paradigm shift that assumes eco-sustainability as a transversal guideline for all actions. With the primary objective of protecting ecosystem balances, improving and enhancing the natural and landscape capital, as well as protecting citizen health and well-being from environmental risks and from those generated by improper anthropization phenomena. The contents of the Plan explicitly emphases the need to «repair the economic and social damage of the pandemic crisis» and to «contribute to addressing the structural weaknesses of the Italian economy», two certainly relevant objectives, the pursuit of which, however, could paradoxically contrast precisely with the transition to a more sustainable development. In the Plan, the green revolution and the ecological transition are resolved in a dedicated axis (waste management, hydrogen, energy efficiency of buildings, without however specific reform guidelines of the broader “energy” sector), while «only one of the projects of the Plan regards directly the theme Biodiversity / Ecosystem / Landscape, and in a completely marginal way» (CATAP, 2021). Actions are also limited for assessing the environmental sustainability of the interventions, except the provision of an ad hoc Commission for the streamlining of some procedural steps and a generic indication of compliance with the DNSH-Do not significant Harm criterion (do not cause any significant damage), without specific guidelines on the evaluation methods. Moreover, little or nothing in the Plan refers on actions and investments in urban renewal, abandoned heritage recovery3, of in protecting and enhancing areas characterized by environmental sensitivity/fragility; situations widely present on the national territory, which are instead the first resource for a structural environmental transition. Finally yet importantly, the well-known inability to manage expenditure and the public administration inefficiencies must be considered: a limit not only to the effective implementation of projects, but also to the control of the relationship between time, costs and quality (also environmental) of the interventions. In many places, the Plan has been talked about as an opportunity for a real “reconstruction”, similar to that of post-war Italy; forgetting that the socio-economic renaissance was driven by the INA-Casa Plan4, but also by a considerable robustness of the cultural approach in the research and experimentation of new housing models (Schiaffonati, 2014)5. A possible “model”, which – appropriately updated in socio-technical and environmental terms – could be a reference for an incisive governmental action aiming at answering to a question – the one of the housing – far from being resolved and still a priority, if not an emergency. The crisis also implies the deployment of new skills, with a review of outdated disciplinary approaches, abandoning all corporate resistances and subcultures that have long prevented the change. A particularly deep fracture in our country, which has implications in research, education and professions, dramatically evident in the disciplines of architectural and urban design. Coherently with the EU Strategic Agenda 2019-2024 and the European Pillar of Social Rights, the action plan presented by the Commission in March 2021, with the commitment of the Declaration of Porto on May 7, sets three main objectives for 2030: an employment rate higher than 78%, the participation of more than 60% of adults in training courses every year and at least 15 million fewer people at risk of social exclusion or poverty6. Education, training and retraining, lifelong learning and employment-oriented skills, placed at the center of EU policy action, now require large investments, to stimulate employment transitions towards the emerging sectors of green, circular and digital economies (environmental design and assessment, risk assessment & management, safety, durability and maintainability, design and management of the life cycle of plans, projects, building systems and components: contents that are completely marginal or absent in the current training offer of Architecture). Departments and PhDs in the Technological Area have actively worked with considerable effectiveness in this field. In these regards, we have to recall the role played by Romano Del Nord «protagonist for commitment and clarity in identifying fundamental strategic lines for the cultural and professional training of architects, in the face of unprecedented changes of the environmental and production context» (Schiaffonati, 2021). Today, on the other hand, the axis of permanent and technical training is almost forgotten by ministerial and university policies for the reorganization of teaching systems, with a lack of strategic visions for bridging the deficit of skills that characterizes the area of architecture on the facing environmental and socio-economic challenges. Also and precisely in the dual perspective of greater interaction with the research systems and with the world of companies and institutions, and of that trans- and multi-disciplinary dimension of knowledge, methods and techniques necessary for the ecological transition of settlement systems and construction sector. Due to the high awareness of the Technological Area about the multifactorial and multi-scale dimension of the crises that recurrently affect our territories, SITdA has been configured since its foundation as a place for scientific and cultural debate on the research and training themes. With a critical approach to the consoling academic attitude looking for a “specific disciplinary” external and extraneous to the social production of goods and services. Finalizing the action of our community to «activate relationships between universities, professions, institutions through the promotion of the technological culture of architecture [...], to offer scientific-cultural resources for the training and qualification of young researchers [...], in collaboration with the national education system in order to advance training in the areas of technology and innovation in architecture» (SITdA Statute, 2007). Goals and topics which seem to be current, which Techne intends to resume and develop in the next issues, and already widely present in this n. 22 dedicated to the Circular Economy. A theme that, as emerges from the contributions, permeates the entire field of action of the project: housing, services, public space, suburbs, infrastructures, production, buildings. All contexts in which technological innovation invests both processes and products: artificial intelligence, robotics and automation, internet of things, 3D printing, sensors, nano and biotechnology, biomaterials, biogenetics and neuroscience feed advanced experiments that cross-fertilize different contributions towards common objectives of circularity and sustainability. In this context, the issue of waste, the superfluous, abandonment and waste, emerge, raising the question of re-purpose: an action that crosses a large panel of cases, due to the presence of a vast heritage of resources – materials, artefacts, spaces and entire territories – to be recovered and re-functionalized, transforming, adapting, reusing, reconverting, reactivating the existing for new purposes and uses, or adapting it to new and changing needs. Therefore, by adopting strategies and techniques of reconversion and reuse, of re-manufacturing and recycling of construction and demolition waste, of design for disassembly that operate along even unprecedented supply chains and which are accompanied by actions to extend the useful life cycle of materials , components and building systems, as well as product service logic also extended to durable goods such as the housing. These are complex perspectives but considerably interesting, feasible through the activation of adequate and updated skills systems, for a necessary and possible future, precisely starting from the ability – as designers, researchers and teachers in the area of Architectural Technology – to read the space and conceive a project within a system of rationalities, albeit limited, but substantially founded, which qualify the interventions through approaches validated in research and experimental verification. Contrarily to any ineffective academicism, which corresponds in fact to a condition of subordination caused by the hegemonic dynamics at the base of the crisis itself, but also by a loss of authority that derives from the inadequate preparation of the architects. An expropriation that legitimizes the worst ignorance in the government of the territories, cities and artifacts. Education in Architecture, strictly connected to the research from which contents and methods derive, has its central pivot in the project didactic: activity by its nature of a practical and experimental type, applied to specific places and contexts, concrete and material, and characterized by considerable complexity, due to the multiplicity of factors involved. This is what differentiates the construction sector, delegated to territorial and urban transformations, from any other sector. A sector that borrows its knowledge from other production processes, importing technologies and materials. With a complex integration of which the project is charged, for the realization of the buildings, along a succession of phases for corresponding to multiple regulatory and procedural constraints. The knowledge and rationalization of these processes are the basis of the evolution of the design and construction production approaches, as well as merely intuitive logics. These aspects were the subject of in-depth study at the SITdA National Conference on “Producing Project” (Reggio Calabria, 2018), and relaunched in a new perspective by the International Conference “The project in the digital age. Technology, Nature, Culture” scheduled in Naples on the 1st-2nd of July 2021. A reflection that Techne intends to further develop through the sharing of knowledge and scientific debate, selecting topics of great importance, to give voice to a new phase and recalling the practice of design research, in connection with the production context, institutions and social demand. “Inside the Polycrisis. The possible necessary” is the theme of the call we launched for n. 23, to plan the future despite the uncertainties and risks, foreshadowing strategies that support a unavoidable change, also by operating within the dynamics that, for better or for worse, will be triggered by the significant resources committed to the implementation of the Recovery Plan. To envisage systematic actions based on the centrality of a rational programming, of environmentally appropriate design at the architectural, urban and territorial scales, and of a continuous monitoring of the implementation processes. With the commitment also to promote, after each release, a public moment of reflection and critical assessment on the research progresses.

But also a «grandiose machine for the housing» (Samonà, 1949), based on a clear institutional and organizational reorganization, with the establishment of a single body (articulated in the plan implementation committee, led by Filiberto Guala, with regulatory functions of disbursement of funds, assignment of tasks and supervision, and in the INA-Casa Management directed by the architect Arnaldo Foschini, then dean of the Faculty of Architecture), which led to the construction of two million rooms for over 350,000 families.

Over the last few decades, plant functional traits (morphological, physiological or phenological features, measurable at the individual level, with a direct or indirect effect on whole-plant fitness) have become widely applied to plant ecology; they provide many insights into plant responses to ecological factors, plant resource acquisition and use, plant assemblages and relations within and between communities, from individual to ecosystem scale. A small set of traits that co-vary recurrently among environments has been used to globally identify certain axes of variation, representing the different plant strategies of resources acquisition and use. In particular, plant species have been classified within a three-way strategy model (CSR) proposed by Grime, according to the distinct trait combinations the are selected under conditions of competition (C), abiotic limitation to growth (S) and periodic biomass destruction (R). Variation in plant functioning (captured by variation in trait values) and species distribution depend on variation in environmental factors that can change gradually through space and time identifying gradients which can be determined by different variables such as altitude, latitude, successional stage, resource availability, soil composition, disturbance events (grazing, fire, trampling, floods etc.) and many others. In this study, plant functional traits and Grime’s CSR adaptive plant strategies were applied in order to gain a functional characterization of plant communities of European vegetation at different levels (within and between communities), to highlight functional similarities and/or differences and to identify common patterns and responses to environmental factors. In details, was investigated the role of an additional trait associated to leaf nutrient content (i.e. leaf sulfur content) within the framework of both global spectrum of plant form and function and the CSR plant adaptive strategies, which resulted to be a consistent addition to the acknowledged and commonly used trait set as it was related to other traits identifying the leaf economics spectrum. Plant inter-specific trait variation in response to changes in single ecological factors was also assessed by considering gradients of different Ecological Indicators referring to key environmental drivers, demonstrating that temperature, light conditions and nutrients were associated with clear effects on plant traits, underlining that responses to changes in land use and increased soil nutrient loading could trigger and strengthen responses to climate alteration. CSR plant strategies were also applied to investigate alien species success and adaption to different habitats, showing that alien species occupy the same CSR space and, therefore, the same niches of native species, being also particularly competitive and associated to relatively productive habitats which are highly prone to invasion. Plant functional traits variation was then studied at the community level considering a topographic sequence in in an alpine pasture, in relation to a variety of abiotic and biotic factors, which showed a strong relationship between vegetation, soil properties, topography, and grazing supporting the ability of plant strategy variation to reflect ecological parameters. In alpine environment, multiple plant communities (floristically and ecologically defined, corresponding to Habitat of EU Commmunity interest) were also functionally characterized along a successional gradient at a regional scale, finding a clear pattern of community-level trait variation that reflected the plant economics spectrum (from acquisitive and fast-growing characteristics in pioneer succession stages, to conservative and stress-tolerant features toward the succession climax) demonstrating that plant trait trade-offs can undergo adaptation at the regional scale caused by local environmental conditions. Finally, the functional characterization of classes of European vegetation using their woody diagnostic species was applied to investigate whether traits and CSR strategies reliably indicate plant-environment relations underpinned by the phytosociological classification method, suggesting a solid link between the two main approaches to vegetation description and classification, phytosociology and functional ecology. This Ph.D. project allowed an overall better insight into plant ecology and functioning, starting from the species-level and then moving to the community-level, analysing plant adaptive strategies and trait interactions, and identifying trends and responses to environmental factors.

The chapter proposes a novel optimization framework to solve the motion planning problem of non-holonomic wheeled mobile robots using swarm algorithms. The specific robotic system considered is a vehicle with approximate kinematics of a car. The configuration of this robot is represented by position and orientation of its main body in the plane and by angles of the steering wheels. Two control inputs are available for motion control including the velocity and the steering angle command. Moreover, the car-like robot is one of the simplest non-holonomic vehicles that displays the general characteristics and constrained maneuverability of systems with non-holonomicity. The control methods proposed in this chapter do not require precise mathematical modeling of every aspect a car-like system. The swarm algorithm-based motion planner determines the optimal trajectory of multiple car-like non-holonomic robots in a given arena avoiding collision with obstacles and teammates. The motion planning task has been taken care of by an adaptive bio-inspired strategy commonly known as Bat Algorithm.

In this paper, a natural approach of the describing for the kids which it is brought into use, by making the image engraving technique of Deep Learning into thought. The previous work opens the technique for a course semantic mix plan (CSF) to mine the specialist features to encode the image content through thought instrument. A CSF benefits by three sorts of visual thought semantics which including the thing level, picture level, and spatial thought features, in three-stage course way. In the viewpoint on the current structure, the model takes the moved picture given by the customer as the information and starts recording the image what a PC find in human standard language with point by point explicit presents in the image appropriately exhibiting the significance of picture captioning. This strategy can be applied to the field of youngster’s tutoring to make them pattern of adapting also entrancing. Fundamentally, we facilitate thought instrument with three kinds of features to orchestrate the setting data about the photos from differentviewpoints.

The digital transformation in the world of work has profound effects on the processes of career orientation and the transition between school and work. Together with international partners from Bulgaria, Germany, Greece, Spain, Italy and Hungary, a digital mentoring concept to secure the employability of young people has been or is being investigated in the three-year EU project "Career 4.0". The focus is on the further development of a personal development plan with the help of which the young people can reflect on their future employment opportunities. Compared to other teaching-learning situations, this is a learning process that is open to development without a predetermined true or false, as is usually the case with mathematical tasks, for example. This places special demands on the mentors when it comes to assessing which forms of feedback are particularly beneficial for the young people and which prove to be less beneficial.Within the framework of the EU project, empirical studies were carried out which came to the conclusion that the quality of the feedback that mentors give to mentees is assessed very dif-ferently by these groups of participants. The mentees see considerable potential for improve-ment when it comes to the quality of the feedback from the mentors. In contrast, the mentors themselves are not as critical of their activities in giving feedback. Over 60 mentees and over 30 mentors have participated in the empirical study so far.The starting point for the study is the meta-analysis of the research team around Hattie et al. (2016). They differentiate between the following forms of feedback: (1) task-related, (2) pro-cess-related, (3) self-regulation-related and (4) person- or self-related feedback. According to the evaluation of their meta-analysis, the second and third forms of feedback have the greatest effect on learning outcomes.Furthermore, scientific studies have shown that the acceptance of feedback depends on numerous influencing factors, which can be assigned to four areas: Characteristics of (1) the feedback message, (2) the feedback source, (3) the feedback recipient and (4) the feedback context. The effect of feedback can be related to three levels, following the psychology of lear-ning: (1) cognitive (e.g. closing competence gaps), (2) metacognitive (e.g. supporting self-assessment and self-awareness) and (3) motivational level (e.g. promoting readiness). How the feedback recipients (here: the young people) ultimately deal with the feedback also depends on their causal attribution, i.e. which reasons they see as causal for their progress or the failure of their actions. If, for example, they attribute their inadequate task performance to environmental factors, e.g. difficult and unfair tasks or disproportionate time pressure, or if they see the reasons in themselves, e.g. in their lack of commitment or insufficient skills, this has very different effects on the effects of the feedback. Among other things, this can lead to a "self-esteem distortion" if, for example, negative results are primarily attributed to external circumstances. The research project is also investigating the extent to which AI tools can help to make feed-back even more effective and efficient for learners. In order to provide IT and AI solutions (such as adaptive learning systems, learning analytics, intelligent CBR recommendation sys-tems) to support the giving of feedback, e.g. with the help of a learning platform, it is advantageous and necessary to make the feedback process transparent by using a process mo-delling approach and to work out individual process steps.Hattie, J. & Timperley, H.
