The article discusses issues of a holistic approach to the study of entrepreneurship development at the regional level. The methodological basis of the study is the systematic approach and the concept of entrepreneurial ecosystems based on it, which is used to study entrepreneurship at the regional level. A general approach to defining the structural organization of a regional entrepreneurial ecosystem is presented, which involves the identification of four types of mutually integrated subecosystems: business ecosystems, innovation ecosystems, knowledge ecosystems and enterprise support (promotion) ecosystems. It is determined that the parameters of the development of subecosystems, their combination effect on the creation, discovery and use of entrepreneurial opportunities in the local spatial environment determine the productivity of the regional entrepreneurial ecosystem. It is justified that the proposed structuring gives a clearer view from the point of view of forming and setting up an enterprise productivity management system The approach presented in the article provides an understanding of the general logic of the functioning of the regional entrepreneurial ecosystem, which, in turn, allows the development and implementation of management tools that provide new opportunities for increasing the productivity of the regional entrepreneurial ecosystem

We merge inclusive wealth theory with ecosystem-based management (EBM) to address two challenges in the science of sustainable management of ecosystems. First, we generalize natural capital theory to approximate realized shadow prices for multiple interacting natural capital stocks (species) making up an ecosystem. These prices enable ecosystem components to be better included in wealth-based sustainability measures. We show that ecosystems are best envisioned as portfolios of assets, where the portfolio’s performance depends on the performance of the underlying assets influenced by their interactions. Second, changes in ecosystem wealth provide an attractive headline index for EBM, regardless of whether ecosystem wealth is ultimately included in a broader wealth index. We apply our approach to the Baltic Sea ecosystem, focusing on the interacting community of three commercially important fish species: cod, herring, and sprat. Our results incorporate supporting services embodied in the shadow price of a species through its trophic interactions. Prey fish have greater shadow prices than expected based on market value, and predatory fish have lower shadow prices than expected based on market value. These results are because correctly measured shadow prices reflect interdependence and limits to substitution. We project that ecosystem wealth in the Baltic Sea fishery ecosystem generally increases conditional on the EBM-inspired multispecies maximum sustainable yield management beginning in 2017, whereas continuing the current single-species management generally results in declining wealth.

The number, importance, and popularity of rankings measuring innovation performance and the strength and resources of ecosystems that provide its spatial framework are on an increasing trend globally. In addition to influencing the specific decisions taken by economic actors, these rankings significantly impact the development of innovation-related policies at regional, national, and international levels. The importance of startup ecosystems is proven by the growing scientific interest, which is demonstrated by the increasing number of related scientific articles. The concept of the startup ecosystem is a relatively new category, the application of which in everyday and scientific life has been gaining ground since the end of the 2000s. In parallel, of course, the demand for measurability and comparability has emerged among decision-makers and scholars. This demand is met by startup ecosystem rankings, which now measure and rank the performance of individual ecosystems on a continental and global scale. However, while the number of scientific publications examining rankings related to higher education, economic performance, or even innovation, can be measured in the order of thousands, scientific research has so far rarely or tangentially addressed the rankings of startup ecosystems. This study and the related research intend to fill this gap by presenting and analysing the characteristics of global rankings and identifying possible future research directions.

Selecting an appropriate model for simulating ecosystem respiration is critical in modeling the carbon cycle of terrestrial ecosystems due to their magnitude and high variations in time and space. There is no consensus on the ideal model for estimating ecosystem respiration in different ecosystems. We evaluated the performances of six respiration models, including Arrhenius, logistic, Gamma, Martin, Concilio, and time series model, against measured ecosystem respiration during 2014–2018 in four grassland ecosystems on the Mongolian Plateau: shrubland, dry steppe, temperate steppe, and meadow ecosystems. Ecosystem respiration increased exponentially with soil temperature within an apparent threshold of ~19.62 °C at shrubland, ~16.05 °C at dry steppe, ~16.92 °C at temperate steppe, and ~15.03 °C at meadow. The six models explained approximately 50–80% of the variabilities of ecosystem respiration during the study period. Both soil temperature and soil moisture played considerable roles in simulating ecosystem respiration with R square, ranging from 0.5 to 0.8. The Martin model performed better than the other models, with a relatively high R square, i.e., R2 = 0.68 at shrubland, R2 = 0.57 at dry steppe, R2 = 0.74 at temperate steppe, and R2 = 0.81 at meadow. These models achieved good performance for around 50–80% of the simulations. No single model performs best for all four grassland types, while each model appears suitable for at least one type of ecosystem. Models that oil moisture include models, especially the Martin model, are more suitable for the accurate prediction of ecosystem respiration than Ts-only models for the four grassland ecosystems.

Under the fierce business competition and sustainable development pressure, the pattern of enterprise innovation has gradually changed from independent innovation to cooperative innovation. As a collection of multi-type innovation actors, the innovation ecosystem provides opportunities and platforms for cooperative innovation among government–industry–university–research institutions. While the present studies on innovation ecosystems are mostly from the perspective of the system level, few studies pay attention to the innovation mechanism of small and medium-sized manufacturing enterprises (SMMEs) in the innovation ecosystem. Therefore, this study takes SMMEs embedded in innovation ecosystems as research objects and explores the factors affecting green innovation. We constructed a theoretical model to explain the effect of innovation eco-embeddedness on green innovation performance based on ecosystem theory and network embeddedness theory; we then collected 363 samples of SMMEs in China through surveys and further tested the data empirically. The results show that the innovation eco-embeddedness (IEE) of SMMEs has a positive effect on their green innovation performance (GIP), and their green value co-creation practices (GVCCPs) partially mediate the relationship between IEE and GIP. Moreover, ecological norms (ENs) in the innovation ecosystem not only positively moderate the impact of IEE on GVCCPs but also positively moderate the mediating role of GVCCPs. This study enriches the relevant research on innovation ecosystems from the perspective of non-core enterprises and provides a theoretical basis and practical reference for SMMEs to implement green innovation practices and realize growth through innovation ecosystems.

The two most significant signatures of the Anthropocene—agriculture and urbanisation—have yet to be studied synoptically. The term periurban is used to describe territory where the urbanising trend of the planet extends into multiscapes. A periurban praxis is required that spatially reconciles urbanisation and agriculture, simultaneously permitting urban growth and the enhancement of critical ecosystem services provided by agricultural hinterlands. This paper presents a synthesis of four fields of ecological research that converge on periurban multiscapes—ecological urbanism, landscape ecology, ecosystem services science and agroecology. By applying an ecosystem services approach, a diagram is developed that connects these fields as a holistic praxis for spatially optimising periurban multiscapes for ecosystem services performance. Two spatial qualities of agroecology—‘ES Density’ and ‘ES Plasticity’—potentiate recent areas of research in each of the other three fields—ecology for the city from ecological urbanism, landscape metrics from landscape ecology (particularly the potential application of fractals and surface metrics) and ecosystem services supply and demand mapping and ‘ES Space’ theory from ecosystems services science. While the multifunctional value of agroecological systems is becoming widely accepted, this paper focuses on agroecology’s specific spatial value and its unique capacity to supply ecosystem services specifically tailored to the critical ecosystemic demands of periurban multiscapes.

The article proposes a model of a multi-level regional ecosystem of technological entrepreneurship and a methodology for assessing its effectiveness. The problems of innovative development of high-tech industries are significant, but only a small part of first-time entrepreneurs associate their businesses with high technology. In Russia, only 3% of startups emerge at universities. The most favorable environment for the development of technological entrepreneurship is entrepreneurial ecosystems covering university, regional and sectoral levels. The article focuses on the formation of technological entrepreneurship ecosystems in the regions that generate business projects with a high potential for market success. Using the ecosystem approach, the theory of entrepreneurship, the structural and functional typology of economic systems, the study discusses a methodical approach to the creation and development of regional ecosystems of student technological entrepreneurship. The paper shows the object, project, process, and environmental elements of the regional ecosystem of student technological entrepreneurship. Methodology for assessment of the performance of regional ecosystems of student technological entrepreneurship is proposed, including assessment at the level of university (the effectiveness of educational technologies, programs, climate, and infrastructure), industry and the region. The results are significant for the formation of an optimally functioning economy in the current conditions, the acceleration of import substitution, and the achievement of the country's technological sovereignty.

Banks still play a key role in monetary transactions, but at the present stage their role for customers is declining. In the near future, many agreements may not require the involvement of an intermediary. Therefore, banks need to rethink their business models and find new ways to stay relevant to their customers. Despite the development of fintech companies, banking and, moreover, the financial market will not disappear, but we can conclude that the reasons for the preservation and, consequently, the direction of transformation of the financial market will be different. Banking institutions need to build a new model of customer relations to establish trusting relationships, on the basis of which continuous business growth is possible. The introduction of banking ecosystems is inevitable, and Ukraine has great potential in this direction. Efficient operation of its own ecosystem platform provides endless advantages of the bank over its competitors. Therefore, such a platform in the long run will allow customers to perform everyday operations conveniently and most importantly in an accessible format. The main advantages of the ecosystem of innovation banking activity include: expanding the list of innovative products and services for existing and new customers, reducing the cost of innovation; accelerate the introduction of innovations in the ecosystem through more dynamic feedback with all participants in the ecosystem and increase customer loyalty; formation of new principles of interaction between participants in the innovation process in order to provide a wider range of innovative banking products and services. Digital ecosystems are a promising business model for banks, as they can not only attract and retain customers, but also generate income beyond their core business. In addition, cooperation with other companies in the form of commercial partnerships creates an attractive income and synergy for banks

Resumo:

Coastal ecosystems are crucial to sustain productive and functioning seascapes because they provide numerous ecosystem services. However, they are under threat and overburdened by multiple anthropogenic land-based and marine-based threats. Managing these threats is challenging because governance of the activities from which threats derive is often segregated and atomistic. Therefore, it is important to assess how management performs across the seascape to ensure adequate protection for coastal ecosystems from multiple threats. Assessing management performance, defined as the ability to meet management objectives, can help managers identify under-performing sites that may need extra management attention (e.g., enforcement, capacity building, or monitoring). Further, it can infer the recovery potential of targeted species or habitats to inform on biologically realistic performance targets. We use the systematic conservation planning framework to explore targeted questions about conservation planning, to identify management gaps and inform on global and regional management decisions.This work begins by asking a series of questions about why management is failing to protect one of the most neglected coastal ecosystems, seagrass. The underlying reason is that seagrass ecosystems are not recognised in legislation or policy and therefore their status and trends are not evaluated against any performance targets. This work has formed part of a global movement to improve the management of seagrass ecosystems, together with authorities charged with global governance of the environment. I then consider how performance targets take into account the social and environmental drivers of fish biomass and assess how this shapes fish recovery. I use this information to inform on management decisions in two case-studies: the northern region of New South Wales, Australia, and in two regional Marine Protected Areas (MPAs) in southern Raja Ampat, Indonesia. In the NSW case study, I identify coastal areas that are at greatest risk to cumulative threats and suggest how management performance could be improved to protect temperate reef fish. In the Indonesian case-study, I suggest that to effectively evaluate MPA performance, it is critical to link historical threats and environmental conditions with coral reef fish outcomes. I then return to seagrass ecosystems as a case study to refine performance targets for monitoring to enable better detection of ecosystem trends. This work, carried out in southern Moreton Bay, Queensland, indicated that metabolomics could allow ecosystem trends to be identified more consistently and with greater accuracy than current methods. In my final chapter, I discuss the implications of these findings and make recommendations for key areas of further research. Each chapter of this thesis, although broad in design, has the same application to inform managers to make better decisions to protect coastal ecosystems. All chapters have an applied outcome and have utilised collaborators to make the information accessible to conservation managers.

This thesis and portfolio of compositions are the result of four years of research conducted through compositional practice and theoretical reflection. This thesis examines in some depth, what the art and craft of composition could be in the context of information age paradigms of communication and interaction. It provides an investigation into compositional approaches fitting to contemporary means of music-making. The focus of this project is composition through real-time, interactive performance systems, this subject is examined within the wider context of network performance, musical interaction and design, live electronics, live scoring, spatial consideration in composition, and new notational practices. This thesis presents the notion of a performance ecosystem, a ground from which a work of art can emerge through the act of performance. The performance ecosystem is conceived of as a self-generating environment that engages a process of genetic replication to expand the system in scope and complexity. Within these performance ecosystems, actions and interactions are generative, and the work is negotiated in real-time between multiple, independent yet interdependent actors. The product of this activity is not only the ensuing sounds, movements, and images that are created, but also the system, with all of its infrastructure and possibilities, and the performance act, as a combination of negotiations and explorations, through which each performer and experiencer partakes in a literal journey through the work. I believe that the performance ecosystem presents a satisfying framework for artistic creation in the context of contemporary constructs of creativity, thought, relationship and being and the way they are represented, experienced and engendered.

Purpose – This dissertation in practice is an evaluation study conducted at Iowa State University, entitled, Learning Ecosystem Assessment Review of Needs (LEARN). The evaluation posed these questions: (a) What educational technologies are currently used and what technologies will be needed in the future? (b) What are the attitudes and practices of faculty and students toward online and blended learning? (c) What academic technology support services are used? What are the perceptions of the support provided for the application of academic technologies? Methodology/design – The study was a mixed-methods design employing interviews with deans and focus groups and surveys of faculty and students. Findings – Iowa State University faculty and students use a wide array of academic technologies both in physical and virtual classrooms. The prevailing sentiment regarding the need for future academic technologies is not for new offerings and new features but for easier to use, more reliable technologies, and more timely support. Although Iowa State University has formally adopted online learning by offering numerous programs and courses, the university is in the early stages of adopting blended learning. Implications – The results and implications of the study inform the university on next steps to ready the institution for leveraging technology and preparing for the transformation toward strategic adoption of online and blended learning. The author outlines an organizational learning approach to manage change and promote adoption of blended learning.

The effect of increased neutral detergent fibre digestibility (NDFD) of sugarcane silage on intake, rumen kinetics and metabolism, microbial population, performance, and body fatness of beef cattle was evaluated through two trials. In the metabolism trial, eight ruminal-cannulated Nellore steers were used in a replicated 4×4 Latin square design. In the performance trial, forty-eight Nellore young bulls were used in a complete randomized block design with a 2×2 factorial arrangement of treatments. Two sugarcane genotypes with high or low NDFD harvested for silage in two maturity stages were used (2 genotypes and 2 maturity stages). Diets were formulated with 40% of sugarcane on dry matter (DM) basis. Intake of DM was likely limited by metabolic feedback. The DM intake (DMI) of cannulated steers was reduced when late-maturity sugarcane was fed, but only with low-NDFD genotype. Turnover and passage rate of NDF was accelerated when high-NDFD genotype was fed. Rumen DM, NDF and iNDF pools were greater when diets with the low-NDFD genotype were fed. There was a tendency for greater relative populations of F. succinogenes and R. albus when animals were fed with diets containing low-NDFD genotype. Performance and carcass characteristics were not affected by treatments. Excess of NFC and fermentation end products of sugarcane silage can limit intake by metabolic pathway. High-NDFD genotype can accelerated NDF turnover and passage rate in the rumen. Late-maturity ensiled sugarcane can reduce DMI of beef steers fed with low-NDFD genotype. The effect of live yeast (LY - Saccharomyces cerevisiae CNCM I-1077) on in situ fiber digestibility, rumen fermentation, and rumen cellulolytic bacteria population of grazing Nellore cattle was evaluated throughout the year. Eight rumen cannulated steers were used in a 2x4 factorial arrangement of treatments: with or without LY, and the four seasons of the year. Yeast was given daily to provide 8x109 CFU per animal. Animals were kept on a rotational grazing system with mineral supplementation. Every 45 d, in situ rumen NDF degradability of 5 reference forages was determined after 24 and 48h incubation. Rumen fluid was collected to measure yeast count and fermentation parameters, and rumen contents collected for quantitative PCR quantification of cellulolytic bacteria. Although pasture composition varied greatly throughout the year, there was no LY*season interaction. Yeast supplementation increased NDF degradability in all seasons. Among the four rumen bacteria evaluated, R. flavefaciens was the most prevalent and LY increased R. flavefaciens population in the summer and spring. Supplementing LY can benefit fibre-degrading bacteria and increase fibre degradability of grazing animals, independently of the season.
O efeito do aumento da digestibilidade da fibra detergente neutro (DFDN) da silagem de cana-de-açúcar sobre consumo, cinética e metabolismo ruminal, população microbiana, desempenho e características de carcaça de bovinos de corte foram avaliados através de dois experimentos. No experimento de metabolismo, oito novilhos Nelore canulados no rúmen foram utilizados em delineamento experimental com dois quadrados latinos 4×4 contemporâneos. No experimento de desempenho, quarenta e oito novilhos nelore foram usados em delineamento em blocos inteiramente casualizados com arranjo de tratamento em fatorial 2×2. Dois genótipos de cana-de-açúcar com alta e baixa-DFDN colhidos para ensilagem em dois estágios de maturidade (2 genótipos e 2 estágios de maturidade). As dietas foram formuladas contendo 40% de silagem de cana-de-açúcar na matéria seca. O consumo de matéria seca (CMS) foi limitado pela via metabólica. O CMS dos novilhos canulados no rúmen foi reduzido quando foram alimentados com a cana-de-açúcar colhida na maturidade tardia, mas somente para o genótipo de baixa-DFDN. A taxa de passagem e o turnover de FDN foram acelerados quando o genótipo de alta-DFDN foi fornecido. O pool ruminal de MS, FDN e FDNi foram maiores para as dietas contendo o genótipo de baixa-DFDN. Houve tendência para maior população relativa de F. succinogenes e R. albus quando os animais foram alimentado com dietas contendo o genótipo de baixa-DFDN. O desempenho e as características de carcaça não foram afetados pelos tratamentos. O excesso de carboidratos não fibrosos (CNF) e os produtos de fermentação das silagens podem limitar o consumo pela via metabólica. O genótipo de alta-DFDN pode acelerar a taxa de passagem e o turnover de FDN no rúmen. O CMS pode ser reduzido quando o genótipo de baixa-DFDN é colhido para ensilagem com maturidade tardia. O feito da suplementação com levedura viva (LV - Saccharomyces cerevisiae CNCM I-1077) sobre a digestibilidade in situ, fermentação ruminal e população de bactérias celulolíticas no rúmen de bovinos Nelore em pastejo foi avaliado ao longo de um ano. Oito novilhos canulados no rúmen foram usados em arranjo fatorial 2×4: com ou sem LV e quantro estações do ano. O tratamento com LV foi realizado diariamente para promover uma suplementação de 8x109 UFC por animal. Os animais foram mantidos em sistema de pastejo rotativo com suplementação mineral. A cada 45 dias, foi realizada a degradação de FDN n situ de 5 forragens referencia, determinada após 24 e 48h de incubação ruminal. O fluido ruminal foi coletado para avaliar a contagem de leveduras e os parâmetros de fermentação, e ainda para a quantificação de bactérias celulolíticas por PCR. Mesmo com grande variação da qualidade do pasto ao longo do ano, não foi observado interação entre LV*estação do ano. A suplementação com LV aumentou a degradabilidade da FDN em todas as estações do ano. Entre as quatro bactérias ruminais avaliadas, a R. flavefaciens foi a mais prevalente e o tratamento com LV aumentou sua população relativa no verão e na primavera. A suplementação com LV pode beneficiar bactérias degradadoras de FDN e aumentar a digestibilidade ruminal de fibra em animais em pastejo, independentemente da estação do ano.

Questa ricerca ha lo scopo di esplorare, attraverso quattro diversi paper, l’impatto della Digital Transformation sul comportamento e la performance delle imprese innovative, in particolare piccole e medie imprese (PMI). Nel primo articolo, si è cercato di fornire un breve excursus, attraverso una disanima della letteratura, sui meccanismi alla base dei processi di creazione di valore delle imprese attive in un ambiente innovativo, tenendo in particolare considerazione le cosiddette managerial dynamic capabilities. Si è cercato di dimostrare come le tecnologie digitali, quali IoT, Big Data e Intelligenza Artificiale, pur con i loro numerosi vantaggi, siano in grado di fornire solo un piccolo contributo ai processi di creazione di valore delle imprese, se non supportate da un insieme di competenze manageriali e organizzative di vario genere. Alla luce di ciò, si è cercato di superare l’approccio tecno-centrico alla Digital Transformation, sottolineando piuttosto l’alto potenziale delle abilità manageriali e organizzative proprie degli attori di tale processo trasformativo, sia dal lato dell’offerta (fornitori di soluzioni digitali) che della domanda (PMI). Nel secondo articolo è presentata un’analisi empirica a livello regionale che vuole rappresentare una preliminare indagine qualitativa sul ruolo svolto dalla stampa 3D nel contesto manifatturiero italiano. Si è cercato di dimostrare come specifici vantaggi percepiti dalle imprese in riferimento alla stampa 3D possono influenzare in modo significativo il loro comportamento di adozione in merito a questa nuova tecnologia digitale. Inoltre, viene rilevato, attraverso lo studio di più casi aziendali, come la percezione delle imprese manifatturiere italiane sul proprio livello di innovazione sia, il più delle volte, in disaccordo con il loro reale livello di innovatività. Successivamente, nel terzo paper, si è cercato di spostare il focus della ricerca su un piano nazionale, progettando un’articolata web-survey, sulla base delle ultime linee guida dell’OCSE. Si è cercato, in tal modo, di identificare, a livello quantitativo, le abilità manageriali più rilevanti per l’incremento della performance nelle PMI italiane innovative. I risultati ottenuti si sono rivelati perfettamente in linea con la letteratura analizzata nel primo capitolo, specialmente rispetto alle dynamic managerial capabilities ed agli altri asset intangibili cruciali per la performance innovativa delle imprese. Infine, nell’ultimo lavoro di ricerca, si è spostato il focus dell’analisi a livello internazionale, esplorando i meccanismi sottostanti gli effetti della Digital Transformation sulla performance dei system integrators, attori business che forniscono un supporto cruciale alle imprese nella trasformazione dei loro processi di creazione del valore. Rispetto al secondo e al terzo paper in cui l’analisi è stata condotta dal lato della domanda di digitalizzazione, in quest’ultima parte si è adottato il punto di vista dell’offerta, concentrandosi sul ruolo svolto dalle nuove tecnologie digitali e dalle capacità organizzative degli integratori di sistema sulla loro performance. I risultati supportano tutti quelli precedenti e forniscono nuovi interessanti spunti sugli effetti della Digital Transformation nel mondo business.
The aim of this research is to explore, through four different papers, the impact of Digital Transformation on behaviour and performance of innovative firms, especially small and medium- sized companies (SMEs). In the first paper, I tried to provide a brief excursus, through the most relevant literature review, on the mechanisms underlying firms’ value creation processes in a Digital Transformation environment, especially from a dynamic capabilities’ perspective. Therefore, it has been proved that digital technologies such as IoT, Big Data and Artificial Intelligence, albeit their numerous benefits, are able to provide just a little contribution to the firms’ value creation if not supported by a diversified set of managerial and organizational skills. In line with this, I tried to go beyond the technology-centric perspective of Digital Transformation, emphasizing instead the actor-driven organizational transformation of capabilities, both from a supply-side (digital solution providers) and a demand-side perspective (SMEs). In my second paper, I carried on an empirical regional analysis to provide a preliminary qualitative investigation of the role played by 3D-printing (3DP) technology in the Italian manufacturing environment. It is shown that specific 3DP’s benefits can significantly influence the firms’ 3DP adoption behaviour. Moreover, it is demonstrated, through a multiple-case study analysis, how the perception of Italian manufacturing firms about their own innovation level is, most of time, not in line with their real level of innovativeness. Thereafter, in my third paper, I tried to extend the focus of my research on a national level by designing a richer web-survey, based on the last OECD guidelines to identify, in a quantitative way, the main business capabilities impacting on the performance of Italian SMEs with a strong innovation component. The results obtained turned out to be perfectly in line with the relevant literature abovementioned in terms of the crucial role played by dynamic managerial capabilities and intangibles assets on firms’ innovation performance. Finally, in my last research essay, I moved my analysis on an international level, by exploring the mechanisms underlining the effects of the Digital Transformation on system integrators’ performance. Compared to the second and third papers where I analysed the phenomenon of interest by a demand-side perspective, in this last analysis it is adopted a supply-side point of view, focusing on the crucial role played by the organizational capabilities in system integrators’ performance improvement. The results support all the foregoing findings and provide new interesting insights on the effects of Digital Transformation in the business context.

Resumo:

Accurate estimation of the responses of understory plants to natural and anthropogenic disturbance is essential for understanding efficacy and non-target effects of management and restoration activities. However, ability to assess changes in abundance of understory plants that result from disturbance may be hampered by inappropriate sampling methodologies. Conventional methods for sampling understory plants may be robust for common, well-distributed species, but may fail to adequately characterize the abundance of less-common species, which are often the taxa of management concern. I tested conventional and novel approaches to sampling understory plants to determine their efficacy (in terms of number of replicates and time required) for quantifying abundance of plants of varying frequency and spatial heterogeneity on three control and three thinned-and-burned treatment units located within the western Montana block of the Fire and Fire Surrogates Project (FFS) a large-scale investigation of the effects of fuel-hazard reduction treatments on a variety of ecosystem components. In each treatment unit, I used four sampling methods (modified Whittaker plots, Daubenmire transects, point line intercept transects, and strip adaptive cluster sampling) to estimate the cover of 24 understory species that vary in abundance. Compared to Daubenmire and point line intercept transects, modified Whittaker plots estimated cover with the lowest variances and, consequently, for the majority (67%) of species required the smallest sample sizes to accurately measure cover. However, this greater sampling efficiency was offset by increased time required to sample. For species grouped by growth-form and for common species, all three conventional sampling designs (i.e. Daubenmire transects, modified Whittaker plots, and point line intercept transects) were capable of estimating cover with a 50% relative margin of error with reasonable sample sizes (3-36 plots or transects for growth-form groups; 8-14 for common species); however, increasing the precision to 25% relative margin of error required sampling sizes that may be logistically infeasible (11-143 plots or transects for growth-form groups; 28-54 for common species). In addition, all three designs required enormous sample sizes to estimate cover of non-native species as a group (29-60 plots or transects) and of individual less-common species (62-118 plots or transects), even with 50% relative margin of error. Strip adaptive cluster sampling was the only method tested that efficiently sampled less-common species: for Cirsium arvense, an invasive non-native plant, adaptive sampling required five times fewer replicates than needed for modified Whittaker plots and 20 times less than for Daubenmire or point line intercept transects. My findings suggest that conventional designs may not be effective for accurately estimating the abundance of newly establishing, non-native plants as a group or of the majority of forest understory plants, which are characterized by low abundance and spatial aggregation. Novel methods such as strip adaptive cluster sampling should be considered in investigations for which cover of these species is a primary response variable.

Resumo:

Rising temperature caused by global warming alters physiology, phenology and/or distribution in a wide array of plant and animal species, which has dramatic knock-on effects at different levels of organisation. This study investigates the individual and interactive effects of temperature (18ᵒC, 22ᵒC and 30ᵒC) and additions of the macroalga Gracilaria gracilis (high and low) on the performance of the seagrass Zostera capensis, which occurs in Langebaan Lagoon, South Africa over a seven-week period. Results from the laboratory experiment revealed that G. gracilis did not significantly affect the performance of Z. capensis although temperature did result in greater leaf width, fouling and senescent biomass, as well as marginally greater leaf area and lower below-ground biomass at 30ᵒC. Increasing temperature also increased G. gracilis biomass, percent cover and fouling by microalgae. In addition, there was no interaction between temperature and the additions of Gracilaria. The overall findings of this study indicate that Z. capensis abundance is likely to decrease while G. gracilis will conversely increase in abundance in response to warming. Changes in abundance of those two ecosystem engineers highlight the possibility of a phase shift from a seagrass- to macroalgal-dominated state in Langebaan Lagoon.

This research presents a study of digital capabilities in order to better understand these capabilities and the impact of these digital capabilities on digital business performance. The literature indicates that digital capabilities is a critical foundation from which digital business can transform the customer experience, operational processes, and business models. From the theoretical study of these capabilities emerged the following research questions: what are the Digital Capabilities that are related to digital business performance? And, what is the impact of digital capabilities on digital business performance? To answer these questions, the following general objectives were elaborated: to understand what are the digital capabilities that are related to digital business performance, and to measure the impact of digital capabilities on digital business performance. Then research started and is presented in here in four articles that have been developed in sequence in order to answer the research question. So, the first step was a systematic review that was developed in order to understand the digital capabilities state of the art. This research is presented in article 1. In the sequence, qualitative studies were developed, with interviews and case studies presented in article 2 and 3. The second paper examines digital capabilities and their role in the digital business performance. We could better understand the digital capabilities, but it was noticed that ecosystem capability needed more studies as it is a new and fundamental theme for understanding the impact of digital capabilities on the performance of the digital business. So, the third paper was developed to understand the relationship between ecosystems and digital business value. Finally, the research model was adjusted, and a survey was carried out in order to measure the impact of digital capabilities on the performance of the digital business, which is presented in article 4. Finally, it was possible to understand that a digital business should develop digital capabilities in order to be capable of monitoring, being responsive, having efficient digital process and able to belong to other ecosystems what will lead to a improve the digital business performance. In addition, the primary results indicate that responsiveness is a crucial capability that makes a significant impact on digital business performance.

Abstract This book contains 23 chapters divided into seven parts. Part I reviews the key hypotheses in invasion ecology that invoke biotic interactions to explain aspects of plant invasion dynamics; and reviews models, theories and hypotheses on how invasion performance and impact of introduced species in recipient ecosystems can be conjectured according to biotic interactions between native and non-native species. Part II deals with positive and negative interactions in the soil. Part III discusses mutualistic interactions that promote plant invasions. Part IV describes antagonistic interactions that hinder plant invasions, while part V presents the consequences of plant invasions for biotic interactions among native species. In part VI, novel techniques and experimental approaches in the study of plant invasions are shown. In the last part, biotic interactions and the management of ecosystems invaded by non-native plants are discussed.

Resumo:

Water-gas shift membrane reactors (WGS-MRs) offer a pathway to affordable blue H2 generation/purification from gasified feedstock or reformed fuels. To exploit their cost benefits for blue hydrogen production, WGS-MRs� performance needs to be optimized, which includes navigating the multidimensional design space (e.g., temperature, feed pressures, space velocity, membrane permeance and selectivity, catalytic performance). This work describes an equation-oriented modeling framework for WGS-MRs in the Pyomo ecosystem, with an emphasis on model scaling and multi-start initialization strategies to facilitate reliable convergence with nonlinear optimization solvers. We demonstrate, through sensitivity analysis, that our model converges rapidly (< 1 CPU second on a laptop computer) under a wide range of operating parameters (e.g., feed pressures of 1-3 MPa, reactor temperatures of 624-824 K, sweep-to-feed ratios of 0-0.5, and steam/carbon ratios of 1-5). Ongoing work includes (1) validation and calibration of the WGS-MR model using benchtop laboratory data and (2) design, intensification, and optimization of blue H2 processes using the WGS-MR model.

There has been a search for standardized and coherent methods for evaluating environmental performance in the construction sector. Despite its limitations, LCA has been the most used method to perform this task. Given its potential, this study aims to propose an improvement of the methodological and conceptual framework of the LCA model, focused on assessing the environmental performance of construction materials. The aim is to incorporate the precepts of ecosystem theory to mitigate its flaws. Analyzing the LCA normative and making a conceptual comparison with the ecosystem foundations, it was possible to embody the cascade framework and the impact categories of the ecosystem’s approach in the LCA model. The result was the expansion of the system boundaries and the consolidation of a new characterization model.

Resumo:

The overall objective of the whole research was to elucidate the mechanisms by which LAB silage inoculants enhance ruminant performance. The results generated will permit the development of better silage inoculants that maximize both silage preservation and animal performance. For this one-year BARD feasibility study, the objectives were to: 1. determine whether lactic acid bacteria (LAB) used in inoculants for silage can survive in rumen fluid (RF) 2.select the inoculants that survived best, and 3. test whether LAB silage inoculants produce bacteriocins-like substances. The most promising strains will be used in the next steps of the research. Silage inoculants containing LAB are used in order to improve forage preservation efficiency. In addition, silage inoculants enhance animal performance in many cases. This includes improvements in feed intake, liveweight gain and milk production in 25-40% of studies reviewed. The cause for the improvement in animal performance is not clear but appears to be other than direct effect of LAB inoculants on silage fermentation. Results from various studies suggest a possible probiotic effect. Our hypothesis is that specific LAB strains interact with rumen microorganisms which results in enhanced rumen functionality and animal performance. The first step of the research is to determine whether LAB of silage inoculants survive in RF. Silage inoculants (12 in the U.S. and 10 in Israel) were added to clarified and strained RF. Inoculation rate was 10 ⁶ (clarified RF), 10⁷ (strained RF) (in the U.S.) and 10⁷, 10⁸ CFU ml⁻¹ in Israel (strained RF). The inoculated RF was incubated for 72 and 96 h at 39°C, with and without 5 g 1⁻¹ glucose. Changes in pH, LAB numbers and fermentation products were monitored throughout the incubation period. The results indicated that LAB silage inoculants can survive in RF. The inoculants with the highest counts after 72 h incubation in rumen fluid were Lactobacillus plantarum MTD1 and a L. plantarum/P. cerevisiae mixture (USA) and Enterococcus faecium strains and Lactobacillus buchneri (Israel). Incubation of rumen fluid with silage LAB inoculants resulted in higher pH values in most cases as compared with that of un-inoculated controls. The magnitude of the effect varied among inoculants and typically was enhanced with the inoculants that survived best. This might suggest the mode of action of LAB silage inoculants in the rumen as higher pH enhances fibrolytic microorganisms in the rumen. Volatile fatty acid (VFA) concentrations in the inoculated RF tended to be lower than in the control RF after incubation. However, L. plalltarull1 MTDI resulted in the highest concentrations of VFA in the RF relative to other inoculants. The implication of this result is not as yet clear. In previous research by others, feeding silages which were inoculated with this strain consistently enhanced animal performance. These finding were recently published in Weinberg et.al.. (2003), J. of Applied Microbiology 94:1066-1071 and in Weinberg et al.. (2003), Applied Biochemistry and Biotechnology (accepted). In addition, some strains in our studies have shown bacteriocins like activity. These included Pediococcus pentosaceus, Enterococcus faecium and Lactobacillus plantarum Mill 1. These results will enable us to continue the research with the LAB strains that survived best in the rumen fluid and have the highest potential to affect the rumen environment.

This study explores the relationship between the quality of a country’s digital entrepreneurial ecosystem, measured by the Global Index of Digital Entrepreneurship Systems (GIDES), and its economic performance during the COVID-19 pandemic. Based on a cross-country analysis of 100 global economies, we find a positive association between GIDES and economic performance during the pandemic. This suggests that the quality of a country’s environment for digital entrepreneurs can strengthen its economic resilience even in the face of major shocks.

Resumo:

Mobile money taxation gives African governments an opportunity to broaden their fiscal base and explore new revenue-generating possibilities. Cameroon introduced a 0.2 per cent tax on mobile money transfers and withdrawals from 1 January 2022. Our research analyses the behaviour of agents, who act as intermediaries between mobile money account holders and mobile money service providers, before and after the tax on mobile money (MM tax). Agents play a key role in the distribution of mobile money services. Their presence is vital for achieving financial inclusion, especially in areas less served by banks and other traditional financial service providers. An agent’s revenue is mainly derived from commission earned on each transaction – they receive an average of 40–45 per cent of the commission, and the remaining 55–60 per cent is shared between the mobile network operator, partner banks, and agent’s manager (superagent). Given their importance in the mobile money ecosystem, factors that negatively affect the attractiveness of the business for agents could have policy implications on financial inclusion.

To ensure the maintenance and sustainability of social and behavior change (SBC), Breakthrough ACTION/Nigeria is implementing a phased, performance-based community capacity strengthening (CCS) approach that focuses on engaging existing community leaders and structures—namely ward development committees—to increase community self-efficacy, coordinate and support the health ecosystem in general, and to ensure sustained community-level activities supporting behavior change and positive social norms for improved health outcomes. Using a qualitative approach, Breakthrough RESEARCH assessed early successes, challenges, and opportunities for Breakthrough ACTION/Nigeria’s CCS Phase 1 approach in selected wards of the Bauchi and Sokoto states in Nigeria.

Microfinance Institutions (MFIs) are organizations that provide small loans to borrowers who typically lack collateral, steady employment, or a verifiable credit history and therefore do not have access to traditional commercial banking. Blockchain technology could be used to create a more holistic view of the financial position of a potential borrower, which could result in better lending decisions. This study explores how blockchain technology has the potential to assist Microfinance Institutions in the water and sanitation sector through a pilot project developed in Peru. The improvements seen in the existing microfinance ecosystem during the implementation of the blockchain platform can be sorted into two main groups: improved institutional performance, and data ownership for the individuals.

Three-wheelers (3Ws) play a significant role in providing the last-mile connectivity. Electrification of three-wheelers has emerged as a necessity to provide a green and clean last-mile ride. The electrification of three-wheelers poses various key challenges. Alliance for an Energy Efficient Economy (AEEE) and International Copper Association India (ICA) collaborated on this study to identify the key barriers to facilitating the adoption of electric three-wheelers (E3Ws) on the market. The proposed whitepaper aims to identify pathways for a market transformation for electric three-wheelers in India. The whitepaper facilitates the increased adoption of E3Ws in India by examining the perspectives of consumers and different stakeholders involved in the E3W ecosystem – fleet operators, financial institutions, dealerships, and service centres. The study was carried out in three cities – Delhi, Lucknow, and Bangalore, with the majority of the survey (70%) conducted in Delhi. The driver survey was broadly divided into three vehicle segments across the three cities: e-rickshaw, e-auto, and internal combustion engine (ICE). Each vehicle type was further divided into goods and passenger transport, and the findings are presented in this report accordingly. The entire report covers various key aspects related to E3Ws, including purchase, charging, performance, aftersales, safety, retrofitting, etc. Chapter 2 provides an overview of the E3W ecosystem, which includes the classification of E3Ws in India, charging and battery swapping infrastructure, and role of E3Ws in last-mile connectivity, with application in different areas. Chapter 3 discusses the findings and key insights from the consumer survey. It examines the key challenges, concerns, and expectations from the consumer perspective. Chapter 4 presents the key insights from the stakeholder consultation and discusses the various challenges, such as manufacturing concerns, financial challenges, the battery swapping ecosystem, and state policies' role in E3W adoption. Chapter 5 provides recommendations to address the barriers to E3W adoption in India. The recommendations presented in the whitepaper focus on topics ranging from consumer perceptions and demand incentives to addressing product issues such as awareness, servicing, safety, and other related topics. The recommendations comprise important aspects of the E3W ecosystem, such as installing more and regularly maintaining charging points, providing investment support to charging and swapping players, and conducting regular EV awareness forums to educate people about the benefits of EVs. Additionally, providing better training to service center technicians, improving the build quality of EVs through customer feedback, and partnering with financial institutions to provide cheaper loans, will be crucial in overcoming the challenges faced by EV drivers. The market transformation for E3Ws in India will require the stakeholders in the electric vehicle (EV) ecosystem to further deliberate and implement strategies in line with the recommendations presented in the whitepaper.
