Resumen

The Blockchain protocol has become an essential technology capable of providing decentralization solutions for numerous industries. At the core of its progress, the idea of resembling Blockchains through a concept is known as integration. This review focuses on the underlying concept, technology development, and security issues in the interconnectivity of the Blockchain and cross-chain security. These cover the need for Blockchain integration to advance scalability and functionality, successful Blockchain integrations, and sharing insights on compliance. The study uses a systematic review approach whereby the PICOC model guides the research questions to enhance literature acquisition. Blockchain insists on innovations in standardization processes and procedures, high consensus algorithms, and security measures to realize secure cross-chain communication while decentralizing the network. Future research directions focus on scalability solutions, intelligible legislations, and consistent consensus algorithms that will further unlock the ability to use Blockchain for various applications.

Resumen

The cross-chain identity authentication method based on relay chains provides a promising solution to the issues brought by the centralized notary mechanism. Nonetheless, it continues to encounter numerous challenges regarding data privacy, security, and issues of heterogeneity. For example, there is a concern regarding the protection of identity information during the cross-chain authentication process, and the incompatibility of cryptographic components across different blockchains during cross-chain transactions. We design and propose a cross-chain identity privacy protection method based on relay chains to address these issues. In this method, the decentralized nature of relay chains ensures that the cross-chain authentication process is not subject to subjective manipulation, guaranteeing the authenticity and reliability of the data. Regarding the compatibility issue, we unify the user keys according to the identity manager organization, storing them on the relay chain and eliminating the need for users to configure identical key systems. Additionally, to comply with General Data Protection Regulation (GDPR) principles, we store the user keys from the relay chain in distributed servers using the InterPlanetary File System (IPFS). To address privacy concerns, we enable pseudonym updates based on the user’s public key during cross-chain transactions. This method ensures full compatibility while protecting user privacy. Moreover, we introduce Zero-Knowledge Proof (ZKP) technology, ensuring that audit nodes cannot trace the user’s identity information with malicious intent. Our method offers compatibility while ensuring unlinkability and anonymity through thorough security analysis. More importantly, comparative analysis and experimental results show that our proposed method achieves lower computational cost, reduced storage cost, lower latency, and higher throughput. Therefore, our method demonstrates superior security and performance in cross-chain privacy protection.

Resumen

The introduction of non-fungible tokens (NFTs) has revolutionised digital ownership and asset management in the quickly changing environment of blockchain technology. NFTs are a kind of token that cannot be exchanged for another token. On the other hand, as the market for NFTs continues to grow, customers are becoming more and more interested in interoperability across various blockchain networks. Cross-chain non-fungible token markets have been developed as a result of this necessity. These marketplaces make it possible for different blockchain ecosystems to engage in transactions and interactions with one another. LayerZero and Chainlink are two technologies that are very significant in addressing the difficulty of interoperability across different chains.

Resumen

The Web3 ecosystem is increasingly evolving to multi-chain, with decentralized applications (dApps) distributing across different blockchains, which drives the need for cross-chain bridges for blockchain interoperability. However, it further opens new attack surfaces, and media outlets have reported serious attacks related to cross-chain bridges. Nevertheless, few prior research studies have studied cross-chain bridges and their related transactions, especially from a security perspective. To fill the void, this paper presents the first comprehensive analysis of cross-chain transactions. We first make efforts to create by far the largest cross-chain transaction dataset based on semantic analysis of popular cross-chain bridges, covering 13 decentralized bridges and 7 representative blockchains, with over 80 million transactions in total. Based on this comprehensive dataset, we present the landscape of cross-chain transactions from angles including token usage, user profile and the purposes of transactions, etc. We further observe that cross-chain bridges can be abused for malicious/aggressive purposes, thus we design an automated detector and deploy it in the wild to flag misbehaviors from millions of cross-chain transactions. We have identified hundreds of abnormal transactions related to exploits and arbitrages, etc. Our research underscores the prevalence of cross-chain ecosystems, unveils their characteristics, and proposes an effective detector for pinpointing security threats.

Resumen

In recent years, the rapid development of blockchain technology has facilitated the transfer of value and asset exchange between different blockchains. However, achieving interoperability among various blockchains necessitates the exploration of cross-chain technology. While cross-chain technology enables asset flow between different blockchains, it also introduces the risk of identity privacy leakage, thus posing a significant threat to user security. To tackle this issue, this article proposes a cross-chain privacy protection scheme that leverages ring signature and relay chain technology. Specifically, this scheme utilizes RCROSS contracts based on ring signatures to handle cross-chain transactions, thereby ensuring the privacy of both parties involved in the transaction. This cross-chain solution demonstrates practicality and efficiency in facilitating cross-chain asset trading. Furthermore, it effectively combats reuse attacks and man-in-the-middle attacks at the application layer while also providing resistance against denial-of-service attacks at the network layer. To validate the proposed cross-chain solution, we conducted tests by constructing a specific cross-chain scenario and by focusing on the natural gas consumption values generated by the RCROSS contract function used in the application chain. The findings indicate that our proposed solution is highly practical in safeguarding the identity privacy of transaction participants. This article’s framework guarantees reliability, security, and efficiency in cross-chain asset transactions. By incorporating ring-based signatures and relay chain technology, users can confidently protect their identity privacy, thus ensuring secure and smooth cross-chain transactions.

Resumen

Cross-chain is an emerging blockchain technology which builds the bridge across homogeneous and heterogeneous blockchains. However, due to the differentiation of different blockchains and the lack of access control and identity authentication of cross-chain operation subjects, existing cross-chain technologies are struggling to accomplish the identity transformation of cross-chain subjects between different chains, and also pose great challenges in terms of the traceability and supervision of dangerous transactions. To address the above issues, this paper proposes a scalable cross-chain access control and identity authentication scheme, which can authenticate the legitimacy of blockchains in the cross-chain system and ensure that all cross-chain operations are carried out by verified users. Furthermore, it will record all cross-chain operations with the help of Superchain in order to regulate and trace illegal transactions. Our scheme is scalable and, at the same time, has low invasiveness to blockchains in the cross-chain system. We implement the scheme and accordingly conduct the evaluations, which prove its security, efficiency, and scalability.

Resumen

Blockchain has become important in business strategy and in technological discussions in industry, academia and government. Irrespective of differing views and beliefs about cryptocurrency, it has triggered significant interest and investment in research in the blockchain space. Enterprise-grade blockchains are being developed to meet specific business requirements. However, the limitations of scalability and interoperability remain design challenges. Technically, interoperability could address scalability by connecting multiple, application-specific blockchain networks. Interoperability is, therefore, emerging as one of the critical requirements of blockchain technology because of the need to address data and value silos. The general definition of interoperability, which stems from an information systems perspective, will not work for blockchain systems. The main challenges are accessing and accepting data from other networks. A preliminary study conducted by the author showed that these networks need to be integrated to interoperate. This research identifies three modes of integration with different security assumptions to address the data access issue. With the data acceptance issue, the value (asset) that each system carries needs to be categorised. Based on the category of asset, specific protocols need to be used to swap or transfer value. This paper proposes an asset classification and design decision framework for cross-chain integration that identifies the type of transfer and its security assumptions in any given scenario. In brief, this thesis proposes a novel protocol to transfer assets between blockchains while preserving the properties needed for value transfer. This protocol is built on the assumption that the integration process happens in multiple steps between mutually agreed parties, and the users initiate the trade. This protocol transfers assets from one network to another in a way that burns the asset on one network and creates proof that will be ported to another network through this integration system. The recipient’s system then mints the same asset on its network with the aid of the proof. The feasibility of the transfer process was tested by deploying the protocol in a test network and evaluating the outcome. A theoretical analysis of the transfer process proves the desired properties, including atomicity, correctness, and security, exist. Formal verification of the protocol in various adversarial conditions has been done. This research shows that atomicity, which is commonly believed to hold in the time-lock mechanism, does not hold in general cross-chain situations. This work verifies that this property only holds under certain assumptions. It also shows that the other two desired properties, correctness and security, hold in the proposed protocol.

Resumen

Le verrou technologique auquel cette thèse s'adresse est donc l'interopérabilité des blockchains. Chaque blockchain est un environnement indépendant avec son propre réseau, son protocole et ses règles. Elles n'ont pas nécessairement été conçues dans l'optique de s'interopérer. En vérifiant l'historique des transactions et en identifiant l'auteur d'une transaction grâce aux signatures numériques, il est possible de vérifier si une transaction peut ou non être ajoutée à la chaîne. Mais à ce jour, aucun mécanisme n'est prévu pour coordonner des transactions entre plusieurs chaînes afin de procéder à un échange. Un système d'échange de crypto-actifs entre deux chaînes cherche à satisfaire les propriétés suivantes; atomicité, l'échange à lieu intégralement ou pas du tout, sécurité, les participants ne risquent pas de perdre leur crypto-actifs et enfin vivacité, la durée de l'échange doit être limitée dans le temps The technological lock that this thesis addresses is therefore the interoperability of blockchains. Each blockchain is an independent environment with its own network, protocol and rules. They were not necessarily designed with interoperability in mind. By checking the history of transactions and identifying the author of a transaction thanks to digital signatures, it is possible to verify whether or not a transaction can be added to the chain. But to date, there is no mechanism for coordinating transactions between multiple chains to make an exchange. A system for exchanging crypto-assets between two chains seeks to satisfy the following properties; atomicity, the exchange takes place entirely or not at all, security, the participants do not risk losing their crypto-assets and finally vivacity, the duration of the exchange must be limited in time

Resumen

Nowadays communication is switching from a centralized scenario, where communication media like newspapers, radio, TV programs produce information and people are just consumers, to a completely different decentralized scenario, where everyone is potentially an information producer through the use of social networks, blogs, forums that allow a real-time worldwide information exchange. These new instruments, as a result of their widespread diffusion, have started playing an important socio-economic role. They are the most used communication media and, as a consequence, they constitute the main source of information enterprises, political parties and other organizations can rely on. Analyzing data stored in servers all over the world is feasible by means of Text Mining techniques like Sentiment Analysis, which aims to extract opinions from huge amount of unstructured texts. This could lead to determine, for instance, the user satisfaction degree about products, services, politicians and so on. In this context, this dissertation presents new Document Sentiment Classification methods based on the mathematical theory of Markov Chains. All these approaches bank on a Markov Chain based model, which is language independent and whose killing features are simplicity and generality, which make it interesting with respect to previous sophisticated techniques. Every discussed technique has been tested in both Single-Domain and Cross-Domain Sentiment Classification areas, comparing performance with those of other two previous works. The performed analysis shows that some of the examined algorithms produce results comparable with the best methods in literature, with reference to both single-domain and cross-domain tasks, in $2$-classes (i.e. positive and negative) Document Sentiment Classification. However, there is still room for improvement, because this work also shows the way to walk in order to enhance performance, that is, a good novel feature selection process would be enough to outperform the state of the art. Furthermore, since some of the proposed approaches show promising results in $2$-classes Single-Domain Sentiment Classification, another future work will regard validating these results also in tasks with more than $2$ classes.

Resumen

Most professionals working within the UK construction industry are familiar with the recommendations of both the Latham and Egan reports, their conclusions called for improvement to the service that the construction industry delivers both for its clients and for the profitability of the enterprises involved. Their recommendations were the impetus for the drive within the industry to use strategic partnering as a replacement for competitive tendering and supply chain management as a means of improving the design process and reducing conflict, in order to achieve greater integration between enterprises involved in business transactions within the construction supply chain. It is however noteworthy that to date few suggestions have been made as to how to achiev e integration of partner enterprises and project teams once an agreement is made or a team formed and thus this paper seeks to investigate why fragmentation is necessary how it adds value to the overall labour process how cross-cultural training techniques can be used as a structured means of achieving the integration of partner enterprises or project teams by reducing conflict. The investigation will follow several paths. First it aims to identify the barriers to successful integration of enterprises within the construction supply chain. Second it reviews the various different techniques by which cross-cultural training is currently carried out and its effectiveness as an assimilation tool. Thirdly it looks at the effectiveness of the application of cross-cultural training in the construction context through an action research exercise carried out on a live project.

Resumen

The current logistics chains must be designed to copy with short life cycles of products, high stock velocity, low degree of predictability etc. The conditions for accuracy, reliability and flexibility of deliveries at the markets have been changing, and that is why it is inevitable to seek new alternative methods that would lead to higher efficiency levels, remaining competitiveness and, at the same time, fulfil the needs and wishes of customers. In this paper I focuse on cross-docking which is a newer distribution method. In the first part of the paper, I try to determine the principles of this operation in distribution, identify individual types of cross-docking and in detail describe the assumptions and conditions under which the method should be implemented to reach the requested results. The paper then continues with an analysis of the current position of cross-docking and there are given several examples of demand driven supply chains that have been using this distribution method at a certain point. These examples are followed with a discussion on current options and problems of implementing cross-docking in the case of retailers and manufacturers.

Resumen

Transaction support for Geo-replicated storage system is one of the most popular challenges in the last few years. Some systems gave up for supporting transactions and let upper application layer to handle it. While some other systems tried with different solutions on guaranteeing the correctness of transactions and paid some efforts on performance improvements. However, there are very few systems that claim the supporting of ACID in the global scale. In this thesis, we have studied on various data consistency and transaction design theories such as Paxos, transaction chopping, transaction chain, etc. We have also analyzed several recent distributed transactional systems. As the result, a Geo-replicated transactional framework, namely Multi Data center Transaction Chain (MDTC), is designed and implemented. MDTC adopts transaction chopping approach, which brings more concurrency by chopping transactions into pieces. A two phase traversal mechanism is designed to validate and maintain dependencies. For cross data center consistency, a Paxos like majority vote protocol is designed and implemented as a state machine. Moreover, some tuning such as executing read-only transaction locally helps to improve performance of MDTC in different scenarios. MDTC only requires 1 cross data center message roundtrip for executing a distributed transaction globally. ACID properties are kept in MDTC. We have evaluated MDTC with an extended TPC-C benchmark on top of Cassandra. The results from various setups have been evaluated and the result shows that MDTC achieves a good performance on throughout and latency. Meanwhile it has very low abort rate and scales well for transactions executed in a global scale.

Resumen

A substantial body of literature is written on the benefits of cross-functional integration between marketing and Supply Chain Management (SCM), nevertheless, a major gap was identified regarding concrete actions needed to be taken to effectively implement such integration and measures to realise and evaluate the integration's impact on performance. Previous research has failed to support the claim about the positive impact of marketing/SCM cross-functional integration on performance. This research proposes a framework to conceptualise marketing/SCM cross-functional integration in order to optimise Supply Chain Performance (SCP) and overall business performance through identifying a set of integrative marketing capabilities and a measurement taxonomy to assess the impact on performance. Due to the novelty of the research, scarce studies and limited cross-functional effective practices, purposive sampling of specific case studies had to be followed. The case studies were selected from the Egyptian Fast Moving Consumer Goods (FMCG) market. Five Multinational Companies (MNC) fulfilled a set of criteria to be used as the research case studies and to reflect a global perspective. The research was divided into three phases, exploratory, explanatory and descriptive. The exploratory phase used a semi-structured research approach. At the exploratory phase, the cross-functional integration status between the marketing department and the SCM departments was examined. Moreover, a set of integrative marketing capabilities was explored. These capabilities are claimed to have the ability to impact SCP and business performance if well aligned between the demand creation side of the organisation (marketing and sales) and the demand fulfilment side (SCM). In addition, a list of integrative practical SCP measurements were investigated at this phase in an attempt to compile a measurement taxonomy capable of assessing the impact of integrating/aligning the identified marketing capabilities with SCM. At the second phase, the explanatory phase, the study attempted to support the results of the exploratory phase. The explanatory phase was divided into two parts, Part A and Part B. This phase employed a more structured approach. Part A resulted in defining the strength of the relationship/influence between each identified marketing capability and each SCP attribute (reliability, agility, responsiveness, cost and asset management). Part B resulted in a proposed comprehensive measurement matrix of 28 Performance Indicators (PI) capable of assessing the impact of marketing/SCM cross-functional integration on SCP and business performance. Thus, a conceptual framework was developed to visualise the measured impact of marketing/SCM cross-functional integration on performance through illustrating the influence of integrating each marketing capability on each SCP attribute and that this influence can be measured by specific corresponding PI. Moreover, in order to practically illustrate a cross-functional integration process, a descriptive research phase was conducted. The integration processes of each case study were mapped and in-depth observations were undertaken to follow and understand the level and scheme of cross-functional integration between the marketing department and the SCM department at the case studies. The descriptive phase resulted in a practical cross-functional integration process model based on the best practices of the five MNCs. This research phase followed an unstructured research approach to fully comprehend the cross-functional integration phenomenon. Finally the cross-functional integration process of Unilever Mashreq, a core case study, was demonstrated and the results of its integrative Key Performance Indicators (KPIs) were shown in order to serve as a real life example reflecting the integration impact on performance. The research provides an original contribution to knowledge by developing a conceptual framework that can benefit companies by offering a tool to evaluate the effectiveness of the marketing/SCM cross-functional integration leading to improved SCP and overall business performance. Moreover, this research also presents a practical integration model to marketing and SCM executives with key cross-functional processes that facilitate implementing successful practices between the demand creation side of the organisation, the marketing department, and the demand fulfilment side of the organisation, the SCM department.

Resumen

The human gut microbiome is a complex ecosystem with hundreds of species interacting with each other and the host. One function of the microbiome is to break down undigested nutrients into smaller nutrients, sometimes available for uptake by the host. The digestion of such macromolecules can involve several species where one feeds on another’s byproducts, forming a large cross-feeding network. The method of digital evolution can be of great aid in studying such complex ecosystems by creating models of the studied system. In this study, the digital evolution software Avida was used to study the effects of perturbations in the system on byproduct cross-feeding chain length. Intense perturbations were found to shorten the chain lengths in general whereas weaker perturbations had either a small or no effect. When perturbations ceased, most byproduct chains displayed recovery to lengths similar to the preperturbation lengths. This indicates that byproduct chain lengths may be kept short by common ecological mechanisms alone, explaining why very long chains are rarely observed while still theoretically possible.

Texto completo

Resumen

Drawing from first-hand experiences managing productive landscapes and seascapes, this brief provides insights on how landscape approaches can promote biodiversity-friendly business through local stewardship, cross-level collaboration and peer learning. Landscape approaches are collaborative strategies that promote biodiversity-friendly business practices. These approaches involve diverse stakeholders, such as local communities and other actors along the value chain, working together at a landscape or seascape scale. Leveraging landscape approaches to advance sustainable business practices for biodiversity is an iterative process, involving adaptation and course correction to accommodate diverse needs and interests among stakeholders. This enhances collaboration across and beyond a value chain. These approaches also capitalize on traditional knowledge, which has been embodied through augmenting local experiences and wisdom to help integrate different knowledge systems that are complementary, creating new business opportunities for biodiversity-friendly innovation. Recommendations: (i) Bolster local stewardship to build and pursue a common vision with enhanced recognition of the livelihood and business values of biodiversity; (ii) Institutionalize a participatory approach to cross-level collaboration that incorporates review and monitoring and capacity development elements; and (iii) Promote biodiversity elements in education and peer-learning to mainstream biodiversity in business in alignment with global policy goals for sustainability.

Texto completo

Resumen

Trade-linked cross-border climate impacts have the potential to severely disrupt the European economy. Yet, the research landscape that surrounds these potential impacts remains in a relatively nascent stage. Importantly, whilst quantitative approaches can be applied in isolation to develop our understanding of cascading cross-border impacts, these should ideally be supplemented by the broader development of knowledge as to how initial climate triggers might evolve via trade systems, might interact with the actions and activities of supply chain actors, and how the wider policy landscape might act as an enabler or barrier to EU climate resilience. The objective of this deliverable is to provide a set of preliminary policy insights resulting from a summary and synthesis of outputs from WP3 of the CASCADES project. Outputs of WP3 encompass the quantitative results of models applied to the exploration of the impacts of climate change on EU trade-linked systems, and qualitative analysis of stakeholder viewpoints – supplemented by information from the wider literature – which highlights key climate-linked concerns, potential responses, and interactions with policy. The deliverable is divided below into three main sections. The first provides a synthesis and related policy implications based on a summary of the outcomes of research activities conducted in CASCADES WP3. Then, the remainder of the report is divided into discrete summaries of the analysis conducted. Analysis Section 1 summarises the quantitative outcomes of WP3 models. Analysis Section 2 summarises the qualitative components of WP3 within the form of three focal trade-linked case studies: a) food systems, b) the soy supply chain, c) energy transition minerals. The depth and breadth of these three case studies differs (more explanation on scope of coverage and methods applied can be found in Analysis Section 2). The Deliverable overall is intended to act as a starting point for (for food systems and soy supply chains) a more in-depth exploration of the policy environment that surrounds trade-linked cross-border impacts that will link to WP6 of the CASCADES project.

Texto completo

Resumen

The size of the digital sector is significant and comprises various activities, processes, and industries. The interdependence of different markets within and across segments of the digital value chain implies that barriers to entry and expansion in one industry can have far-reaching effects on the growth of the rest of the digital sector and the economy, more widely. Ensuring robust competition across the digital value chain is therefore of paramount importance. Internet connectivity is the most critical element of the value chain as it links the various participants in the digital sector to the final users or consumers. It is also the segment that has the highest barriers to entry. Although natural barriers exist, regulatory and strategic barriers further constrain competition. Thus, access regulations will need to be strengthened and enforced. An open access framework and increased transparency will facilitate the growth of broadband. Adapting M&A guidelines, effective cross-sectoral regulatory cooperation, and investment in training will also reduce barriers to entry and expansion. Partnerships between the private and public sectors will also be necessary to reduce the digital divide in the country significantly. The telecommunications industry has been dominated by two vertically integrated firms, which are also expanding their service portfolios to other segments. While vertical integration along the digital value chain could create efficiencies, significant market power could enable anticompetitive conduct and limit innovation. In the digital age, competitive pressures must be built into the entire value chain by lowering barriers to entry and expansion, removing bottlenecks to innovation, and reducing switching costs. Further analysis of particular segments or specific bottlenecks and anti-competitive practices will be useful in crafting appropriate regulatory approaches.

Texto completo

Resumen

The creation of an intelligent supply chain is now an urgent national security priority that cannot be achieved without the joint mobilization of various stakeholders in Canada. It is not, however, an end in itself: the achievement of a single, competitive, sustainable, and consumer-focused domestic market should be the ultimate outcome of the national taskforce needed to collaboratively implement the recommendations of three complementary public policy reports published in 2022 on the state of the supply chain in Canada. The supply chain challenge is vast, and it will only become more complex over time. Governments in Canada must act together now, in conjunction with collaborative efforts with our allies and partners, notably the United States and the European Union, to ensure supply chain resilience in the face of accelerating current and anticipated upheavals, geopolitical conflicts and natural disasters. Québec's geostrategic position is a major asset, and gives it a critical role and responsibility in implementing not only the Final Report of the National Supply Chain Task Force ("ACT"), but also of the recommendations contained in the report published by the Council of Ministers Responsible for Transportation and Highway Safety (COMT) and those contained in the report of the House of Commons Standing Committee on Transport, Infrastructure and Communities published in Ottawa in November 2022, "Improving the Efficiency and Resilience of Canada's Supply Chains". The mobilizing approach towards a common data space for Canada's supply chain is inspired by Advantage St. Lawrence's forward-looking Smart Economic Corridor vision and builds on and integrates experience gained from various initiatives and programs implemented in Canada, the U.S. and Europe, as appropriate. Its initial implementation in the St. Lawrence - Great Lakes trade corridor will facilitate the subsequent access and sharing of data from across the Canadian supply chain in a reliable and secure manner. The accelerated joint development of a common data space is a game-changer not only in terms of solving critical supply chain challenges, but also in terms of the impetus it will generate in the pursuit of fundamental Canadian priorities, including the energy transition. This Bourgogne report offers a four-part synthesis: - An overview of a background characterized by numerous consultations, strategy announcements, measures, and mixed results. - A cross-analysis of the recommendations of three important and complementary public policy reports at federal level, as well as the Quebec strategy, “l'Avantage Saint-Laurent”. - An analysis of the fundamental issues of mobilization capacity, execution, and under-utilization of data. - Some operational solutions for moving into « Action, Collaboration and Transformation » (ACT) mode.

Texto completo

Resumen

The interconnections between countries in a globalizing world continue to deepen and are central to the modern international economy. Yet, governance efforts to build resilience to the adverse risks and impacts of climate change are highly fragmented and have not sufficiently focused on these international dimensions. Relationships between people, ecosystems and economies across borders change the scope and nature of the climate adaptation challenge and generate climate risks that are transboundary (Challinor et al., 2017). Climate impacts in one country can create risks and opportunities – and therefore may require adaptation – in other countries, due to cross-border connectivity within regions and globally (Hedlund et al., 2018). These Transboundary Climate Risks (TCRs) may develop in one location remote from the location of their origin. This dynamic necessitates examining the governance structures for managing climate change adaptation. For example, with regard to trade and international supply chains, climate change impacts in one location can disrupt local economies and vulnerable people’s livelihoods, while also affecting the price, quality and availability of goods and services on international markets (Benzie et al., 2018). Coffee is one of the most traded commodities in the world with an immensely globalized supply chain. The global coffee sector involves more than 100 million people in over 80 countries. Coffee production and the livelihoods of smallholder coffee farmers around the world are at risk due to climate change, threatening to disrupt one of the world’s largest agricultural supply chains. The coffee supply chain represents an important arena for public and private actors to negotiate how resource flows should be governed and climate risks should be managed. Currently, neither governments nor private sector actors are sufficiently addressing TCRs (Benzie & Harris, 2020) and no clear mandates exist for actors to take ownership of this issue. Furthermore, the United Nations Framework Convention on Climate Change (UNFCCC), the main body for climate change policy and governance, does not provide any coherent recommendations on how to manage TCRs. This governance gap raises questions about what methods are likely to effectively reduce climate risk and be taken seriously by coffee market stakeholders. This policy brief explores different ways to govern TCRs, and how public and private actors view their effectiveness and legitimacy. Focusing on the Brazilian-German coffee supply chain, the brief presents a deductive framework of five governance pathways through which TCRs could be managed. It is based on 41 semi-structured interviews with 65 Brazilian and German public and private experts, including roasters, traders, cooperatives, associations and certification schemes, as well as government ministries, international development agencies, international organizations and civil society representatives.

Texto completo

Resumen

Transboundary climate risks pose complex challenges, propagating across borders and sectors and affecting global supply chains, economies and governance systems. However, the ownership of these risks remains unclear, making adaptation efforts fragmented and less effective. This paper introduces a framework to map risk ownership in global supply chains, helping identify key stakeholders, assets and objectives at risk. By applying this framework to the case of Brazilian-produced soy products imported for fish food in Norway, we illustrate how climate risks – and the adaptation measures to address them – extend beyond direct supply chain actors to industries, governments and broader economic systems. The framework highlights the systemic nature of transboundary climate risks, emphasizing the need for coordinated, cross-sectoral approaches to adaptation. It also raises critical questions on fairness and responsibility, as differing risk exposures and incentives influence who takes action. Ultimately, the framework provides a foundation for improving risk governance and enhancing climate resilience in interconnected global systems.

Texto completo

Resumen

The quality and utilization of wheat is largely dependent upon the exact physical/chemical properties of the doughs made from flour/water mixtures. Among the wheat seed components most correlated with dough visoelastic parameters are the high-molecular-weight (HMW) glutenin subunits whose disulfide cross-linked macropolymer is critical for dough functionality. We have used the tools of molecular biology, wheat transformation, heterologous expression of HMW-glutenin subunits in bacteria, and dough micro-mixing experiments to examine some of the molecular basis of HMW-glutenin functionality. In addition, we have developed sets of modified and synthetic gene constructs and transgenic wheat lines that will allow further examination of the role of the HMW-glutenins. Among the results from this work is evidence that the HMW-glutenin repeat domain is directly related to dough properties, the demonstration that interaction between subunits is dependent upon domain presence but not order, a novel understanding of the restrictions on intra-vs inter-chain disulfide bonds, the demonstration that HMW-glutenin genes can be transformed into wheat for simultaneously high expression of the transgene and suppression of the endogenous genes, and the construction of a set of modified HMW-glutenins capable of being epitope tagged for studying polypeptide subcellular processing and the fate of HMW-glutenins in dough mixing experiments.

Morrison, Mark, and Joshuah Miron. Molecular-Based Analysis of Cellulose Binding Proteins Involved with Adherence to Cellulose by Ruminococcus albus. United States Department of Agriculture, 2000. http://dx.doi.org/10.32747/2000.7695844.bard.

Texto completo

Resumen

At the beginning of this project, it was clear that R. albus adhered tightly to cellulose and its efficient degradation of this polysaccharide was dependent on micromolar concentrations of phenylacetic acid (PAA) and phenylpropionic acid (PPA). The objectives for our research were: i) to identify how many different kinds of cellulose binding proteins are produced by Ruminococcus albus; ii) to isolate and clone the genes encoding some of these proteins from the same bacterium; iii) to determine where these various proteins were located and; iv) quantify the relative importance of these proteins in affecting the rate and extent to which the bacterium becomes attached to cellulose. BARD support has facilitated a number of breakthroughs relevant to our fundamental understanding of the adhesion process. First, R. albus possesses multiple mechanisms for adhesion to cellulose. The P.I.'s laboratory has discovered a novel cellulose-binding protein (CbpC) that belongs to the Pil-protein family, and in particular, the type 4 fimbrial proteins. We have also obtained genetic and biochemical evidence demonstrating that, in addition to CbpC-mediated adhesion, R. albus also produces a cellulosome-like complex for adhesion. These breakthroughs resulted from the isolation (in Israel and the US) of spontaneously arising mutants of R. albus strains SY3 and 8, which were completely or partially defective in adhesion to cellulose, respectively. While the SY3 mutant strain was incapable of growth with cellulose as the sole carbon source, the strain 8 mutants showed varying abilities to degrade and grow with cellulose. Biochemical and gene cloning experiments have been used in Israel and the US, respectively, to identify what are believed to be key components of a cellulosome. This combination of cellulose adhesion mechanisms has not been identified previously in any bacterium. Second, differential display, reverse transcription polymerase chain reaction (DD RT-PCR) has been developed for use with R. albus. A major limitation to cellulose research has been the intractability of cellulolytic bacteria to genetic manipulation by techniques such as transposon mutagenesis and gene displacement. The P.I.'s successfully developed DD RT- PCR, which expanded the scope of our research beyond the original objectives of the project, and a subset of the transcripts conditionally expressed in response to PAA and PPA have been identified and characterized. Third, proteins immunochemically related to the CbpC protein of R. albus 8 are present in other R. albus strains and F. intestinalis, Western immunoblots have been used to examine additional strains of R. albus, as well as other cellulolytic bacteria of ruminant origin, for production of proteins immunochemically related to the CbpC protein. The results of these experiments showed that R. albus strains SY3, 7 and B199 all possess a protein of ~25 kDa which cross-reacts with polyclonal anti-CbpC antiserum. Several strains of Butyrivibrio fibrisolvens, Ruminococcus flavefaciens strains C- 94 and FD-1, and Fibrobacter succinogenes S85 produced no proteins that cross-react with the same antiserum. Surprisingly though, F. intestinalis strain DR7 does possess a protein(s) of relatively large molecular mass (~200 kDa) that was strongly cross-reactive with the anti- CbpC antiserum. Scientifically, our studies have helped expand the scope of our fundamental understanding of adhesion mechanisms in cellulose-degrading bacteria, and validated the use of RNA-based techniques to examine physiological responses in bacteria that are nor amenable to genetic manipulations. Because efficient fiber hydrolysis by many anaerobic bacteria requires both tight adhesion to substrate and a stable cellulosome, we believe our findings are also the first step in providing the resources needed to achieve our long-term goal of increasing fiber digestibility in animals.
