Climate change poses one of the greatest challenges on an international scale. Responding to this challenge requires the collective effort of all States, however, primary burden has been placed on climate finance deriving from developed States, reflecting a dichotomy amongst the member States to the UN climate change regime. The climate finance obligation, albeit justified under the UNFCCC and the principle of differentiation, does not come without challenges for both categories of States. Most of these challenges have focused so far on the donor side, as well as the institutional design and policy weaknesses of the development institutions administering and disbursing climate finance. Considerable challenges, however, also exist on the beneficiary side, especially due to the lack of national climate finance readiness and solid institutional frameworks and policies in recipient countries. This paper focuses on the legal aspects of readiness for climate finance examining the regulatory tools currently deployed by developing States to strengthen their domestic capacities. First, it elaborates on the climate finance obligation per se, while embarking on analyzing this obligation and the challenges it entails under the UN climate change framework. Second, it examines the concept of legal readiness by analyzing what it means to be ready for climate finance, the rationale of legal readiness and the role of law in enhancing developing States’ readiness for climate finance. In doing so, the paper elaborates on the existing taxonomies and guidelines on legal readiness for climate finance, as well as the regulatory and policy tools extensively utilized for this purpose in developing countries. Third, the paper demonstrates the case study of Bangladesh as a country that has advanced and adjusted its national legislation and policies, in order to enhance its legal readiness for climate finance.

In the context of robotic software, the selection of an appropriate planner is one of the most crucial software engineering decisions. Robot planners aim at computing plans (i.e., blueprint of actions) to accomplish a complex mission. While many planners have been proposed in the robotics literature, they are usually evaluated on showcase examples, making hard to understand whether they can be effectively (re)used for realising complex missions, with heterogeneous robots, and in real-world scenarios. In this paper we propose ENFORCE, a framework which allows wrapping FM-based planners into comprehensive software engineering tools, and considers complex robotic missions. ENFORCE relies on (i) realistic maps (e.g, fire escape maps) that describe the environment in which the robots are deployed; (ii) temporal logic for mission specification; and (iii) Uppaal model checker to compute plans that satisfy mission specifications. We evaluated ENFORCE by analyzing how it supports computing plans in real case scenarios, and by evaluating the generated plans in simulated and real environments. The results show that while ENFORCE is adequate for handling single-robot applications, the state explosion still represents a major barrier for reusing existing planners in multi-robot applications.

The globalization of food systems has engendered significant changes to the operation and structure of food supply chains (FSCs). Alongside increasing consumer demands for safe and sustainable food products, FSCs are challenged with issues related to information transparency and consumer trust. Uncertainty in matters of transparency and trust arises from the growing information asymmetry between food producers and food consumers. In particular: how and where food is cultivated, harvested, processed, and under what conditions. FSCs are tasked with guaranteeing the highest standards in food quality and food safety-ensuring the use of safe and authentic ingredients, limiting product perishability, and mitigating the risk of opportunism such as quality cheating or falsification of information. A sustainable, food-secure world will require multidirectional sharing of information and enhanced information symmetry between food producers and food consumers. The need for information symmetry will drive transformational changes in FSCs methods of practice and will require a coherent standardized framework of best practice recommendations to manage logistic units in the food chain A standardized framework will enhance food traceability, drive FSC efficiencies, enable data interoperability, improve data governance practices, and set supply chain identification standards for products and assets (what), exchange parties (who), locations (where), business processes (why) and sequence (when). FSCs began to adopt industry-driven supply chain standards in 1974 when the first barcode was scanned at a point-of-sale at Marsh's Supermarket in Troy, Ohio. However, the adoption of standards alone will not adequately address the challenges created by the information asymmetry between food producers and food consumers. Therefore, this paper examines the integration of GS1 standards with the functional components of Blockchain technology as an approach to realize a coherent standardized framework of industry-based tools for successful FSC transformation.

UML models are standard artifacts used by software engineers for designing software. As software is designed, different UML diagram types (e.g., class diagrams and sequence diagrams) are produced by software designers. Since the various UML diagram types describe different aspects of a software system, they are not independent but strongly depend on each other, hence they must be consistent. Inconsistencies cause faults in the final software systems. It is, therefore, paramount that they get detected, analyzed, and fixed. Consistency rules are a useful tool proposed in the literature to detect inconsistencies. They categorize constraints that help in identifying inconsistencies when violated. This case study aims at collecting and analyzing UML models with OCL consistency rules proposed in the literature and at promoting the development of a reference benchmark that can be reused by the (FM-)research community. We collected 33 UML consistency rules and 206 different UML diagrams contained in 34 open-source UML models presented in the literature. We propose an FM-based encoding of the consistency rules in OCL. This encoding allows analyzing whether the consistency rules are satisfied or violated within the 34 UML models. To assess the proposed benchmark, we analyzed how the UML models, consistency rules, diagram types contained in the benchmark help in assessing the consistency of UML models, and the consistency of diagrams across the different software development phases. Our results show that the considered UML models and consistency rules allowed identifying 2731 inconsistencies and that those inconsistencies refer to different software development phases. We concluded that the considered UML models and consistency rules could be considered as an initial benchmark that can be further extended by the research community. [less ▲]

Food systems and food supply chains (FSCs) have undergone significant changes in their operations and structure over the last decade as globalization expands both food choice and availability. As FSCs lengthen, and food passes through extended trading relationships, transparency on food origins, methods of cultivation, harvest, processing as well as labor conditions and sustainability is reduced, along with food trust. Moreover, while the rapid pace of technology innovation benefits FSCs, we are witness to the usage of social media platforms by citizen-consumers to amplify the rhetoric related to recurring incidents and crises in food quality, food safety, food fraud, food security, sustainability, and other ethical lapses. Furthermore, we are witness to new evidence on the global burden of foodborne diseases, including non-communicable diseases that range from severe malnutrition to morbid obesity and from severe illnesses requiring hospitalization to mortality. The World Health Organization claims that thirty-one foodborne hazards cause six-hundred million illnesses and four-hundred and twenty thousand deaths annually. Overcoming these challenges requires a holistic reframing of our food systems and societal challenges. The emergence of the United Nations (UN) Sustainable Development Goals (SDGs) provides an overarching framework for collaboration and alignment. Japan has put forward a vision for a human-centric, technology-enabled future branded as "Society 5.0". Increasingly, the redesign of FSCs necessitates a concerted, multi-stakeholder effort and the development of digitization strategies in order to cope with the evolution toward the vision of Society 5.0 and to achieve the UN SDGs.

This chapter examines recent language education laws in Luxembourg as well as the ways in which early years practitioners appropriated the new policies and put them into practice. The chapter begins with a brief introduction of the linguistic landscape in Luxembourg and a summary of the dynamic development of the country’s early childhood education system. Special emphasis is put on recent changes in language education policies, which call for a more inclusive and multilingual early language education. Monolingual practices now need to open up to flexible language use and offer children opportunities to capitalize on their entire semiotic repertoire for communicating, meaning-making, and learning. The central concerns of this chapter are the ways in which policy changes influence educational practices in formal and non-formal settings and how professional development shapes this process. In order to address these questions, the authors review literature on language education policy, translanguaging and professional development and examine studies on early language education in Luxembourg. Next, they discuss recent initiatives of professional development in formal and non-formal early years settings as well as their outcomes. Finally, they present critical issues such as the practitioners’ reflexivity and responsibility and the sustainability of professional development. Future research directions include family language policies, partnerships between families and early childhood institutions and children’s languaging practices inside and across these institutions.

Drawing on two longitudinal case-studies, this study aimed to identify some salient characteristics of the agentic behaviour of two young emergent multilinguals in two different multilingual contexts: Luxembourg and Israel. Despite the fact that the studies were conducted independently, the two cases were analysed together owing to the similarities in the research methods such as video-recorded observations, and semi-structured interviews with teachers and parents. The data were analysed through thematic and conversational analyses. Findings showed that a boy who learned Luxembourgish in Luxembourg and a girl who learned Hebrew in Israel, were outgoing and active learners who influenced their learning environment. We identified ten types of agentic behaviour, including engaging in repetition after peers and the teacher, creatively producing language, translanguaging, and self-monitoring. Despite differences of the children's sociocultural and linguistic backgrounds, and the language policies of their educational settings, we found a striking overlap in their language-based agentic behaviours. We suggest that the identified types can encourage further research in this field. Although our study with talkative children allowed us to observe many types of agentic behaviours, we cannot claim that less outgoing children or children who do not show the same behaviours do not have ways of expressing their agency.

In diesem Beitrag wird die Bedeutung von nationalen Grenzen für räumliche Identitäten in Grenzregionen analysiert. Dafür wird ein mehrdimensionales Analysemodell entwickelt und am Beispiel der Großregion SaarLorLux gefragt, wie die Einwohner den Raum repräsentieren und wie sie ihre alltagskulturellen Praktiken räumlich organisieren. Außerdem werden räumliche Projektionen im politischen Diskurs aufgedeckt und rekonstruiert, inwiefern diese in Identifizierungsprozessen wirksam sind. Die Betrachtungen stützen sich auf eine Repräsentativbefragung der Einwohner Luxemburgs und der an das Großherzogtum angrenzenden Gebiete in Frankreich, Belgien und Deutschland. Der Beitrag zeigt, dass nationale Grenzen in den Identifikations- und Identifizierungsvorgängen der Einwohner der Großregion SaarLorLux trotz grenzüberschreitender Verflechtungen und Alltagsgeographien eine wichtige Rolle spielen, aber nicht zwangsläufig als stabile Ordnungskategorien.

We propose a novel methodology for designing oversampled discrete Fourier transform-modulated uniform filter banks. The analysis prototype is designed as a Nyquist filter, whereas the synthesis prototype is designed to guarantee perfect reconstruction (PR) considering oversampling. The resulting optimization problem fits into the disciplined convex programming framework, as long as some convex objective function is employed, as the minimization of either the stop-band energy or the maximum deviation from a desired response. The methodology also accounts for near-PR multiplierless approximations of the prototype analysis and synthesis filters, whose coefficients are obtained in the sum-of-power-of-two (SOPOT) space. The quantized coefficients are computed using successive approximation of vectors, which is able to yield filters with a reduced number of SOPOT coefficients in a computationally efficient manner. The proposed methodology is especially appealing for supporting actual hardware deployments, such as modern digital transparent processors to be used in next-generation satellite payloads. [less ▲]

Today, higher education is typically seen as offering the most assured pathways to secure careers and low unemployment rates. Yet, increasingly some groups, not least higher education graduates and their families paying ever-higher tuition fees, question the taken-for-granted contributions higher education makes to individuals and society as a whole. Despite decades of mass higher education expansion, even societies with strong systems continue to struggle to achieve their goal of universalizing participation and equalizing access. While in part this is due to limited public or corporate funding for (affordable) study opportunities, differentiated systems, such as in the US, also lack policy coordination and effective governance, providing a surfeit of options. While participation rates have climbed worldwide, higher education systems continue to produce winners (“insiders”) and losers (“outsiders”), even as the “schooled society” shifts the occupational structure upward. Market-oriented higher education systems face increasing privatization, which also involves financializing university governance. Many states have retrenched investments that had once underwritten universities’ flourishing and their moves toward massification. Tensions have deepened over who should pay for rising costs, exacerbated in an era of increasing status competition via higher education. In the face of such challenges globally, which alternatives exist? A prominent possibility, pioneered in Germany in the 1970s, are “dual study” programs offered by several organizational forms, from vocational academies to universities of applied sciences. Such hybrid programs fully integrate phases of higher education study and paid work in firms. Another potential advantage of apprenticeship training being offered in conjunction with higher education is that this would boost the reputation of apprenticeships overall. The German experience indicates that the attractiveness of the apprenticeship training system as a whole can be bolstered when it offers a viable pathway also for those individuals with a traditional university entrance certificate. If these students seriously consider and choose advanced work-based higher education, this may well increase the standing of apprenticeship training among students, their families, and employers. Thus, dual study programs provide an innovative model for policymaking and implementation. Especially when considering strategies to improve skill formation overall, to reduce the costs individuals must bear in attaining higher education, and to improve the fit between the expectations of employers and potential employees regarding skill formation, dual study programs excel. The origins and contemporary developments in work-based higher education in Germany offer lessons and inspiration for Anglophone countries, with their strong and differentiated higher education systems, to further bolster study programs coordinated with firms.

This paper develops normative approaches for measuring individual-level income insecurity. Using concepts derived from Expected Utility Theory and Prospect Theory, we build a suite of measures designed to capture various facets of psychologically distressing income risk. We present an application for the US and Germany from 1993-2013, employing conditionally heteroskedastic fixed-effects models to generate predictive densities for future incomes. Our results reveal much higher levels of income risk in the US relative to Germany, which can be mostly attributed to a higher level of autonomous, time-invariant volatility. State-by-state variations in liberal/conservative political administrations partially explain our results, and we find some evidence that trade exposure is a contributing factor in the US. [less ▲]

Objective: Identifying factors that control food intake is crucial to the understanding and treatment of eating disorders characterized by binge eating. In healthy individuals, stomach distension plays an important role in the development of satiation, but gastric sensations might be overridden in binge eating. The present study investigated the perception of gastric signals (i.e., gastric interoception) and gastric motility in patients experiencing binge eating episodes, i.e. bulimia nervosa (BN) and binge-eating disorder (BED). Method: Twenty-nine patients with BN or BED (ED group) and 32 age-, sex-, and BMI-matched healthy controls (HC group) participated in the study. The onset of satiation and stomach fullness were assessed using a novel 2-step water load test (WLT-II). Gastric myoelectrical activity (GMA) was measured by electrogastrography (EGG) before and after ingestion of non-caloric water. Results: Individuals in the ED group drank significantly more water until reporting satiation during the WLT-II. The percentage of normal gastric myoelectrical power was significantly smaller in the ED group compared to HC, and negatively related to the number of objective binge-eating episodes per week in bulimic patients. Power in the bradygastria range was greater in ED than in HC subjects. Discussion: Patients with EDs have a delayed response to satiation compared to HC participants, together with abnormal GMA. Repeated binge eating episodes may induce disturbances to gastric motor function. [less ▲]
