Understanding inflation dynamics : Where do we stand ?

I summarize recent progress made in the literature on inflation dynamics. This has been a very productive area of research due to the development of the so-called New Keynesian model and the availability of new macroeconomic and microeconomic evidence. Nevertheless, a number of problems still subsist. In particular the importance of temporary price markdowns to inflation dynamics and the characteristics of the information set price-setters use for their price adjustment decision currently constitute unresolved issuesInflation dynamics, New Keynesian model, sticky prices

Holistic recommender systems for software engineering

The knowledge possessed by developers is often not sufficient to overcome a programming problem. Short of talking to teammates, when available, developers often gather additional knowledge from development artifacts (e.g., project documentation), as well as online resources. The web has become an essential component in the modern developer’s daily life, providing a plethora of information from sources like forums, tutorials, Q&A websites, API documentation, and even video tutorials. Recommender Systems for Software Engineering (RSSE) provide developers with assistance to navigate the information space, automatically suggest useful items, and reduce the time required to locate the needed information. Current RSSEs consider development artifacts as containers of homogeneous information in form of pure text. However, text is a means to represent heterogeneous information provided by, for example, natural language, source code, interchange formats (e.g., XML, JSON), and stack traces. Interpreting the information from a pure textual point of view misses the intrinsic heterogeneity of the artifacts, thus leading to a reductionist approach. We propose the concept of Holistic Recommender Systems for Software Engineering (H-RSSE), i.e., RSSEs that go beyond the textual interpretation of the information contained in development artifacts. Our thesis is that modeling and aggregating information in a holistic fashion enables novel and advanced analyses of development artifacts. To validate our thesis we developed a framework to extract, model and analyze information contained in development artifacts in a reusable meta- information model. We show how RSSEs benefit from a meta-information model, since it enables customized and novel analyses built on top of our framework. The information can be thus reinterpreted from an holistic point of view, preserving its multi-dimensionality, and opening the path towards the concept of holistic recommender systems for software engineering

weltwärts: Volunteers and their Civic Engagement in Germany

The development volunteer service “weltwärts” enables young adults to participate in a volunteer service in countries of the Global South. The weltwärts programme is implemented by over 150 civil society sending organisations and their partner organisations in the host countries. Since the programme was founded in 2007, more than 30,000 young adults have already taken part in weltwärts. Measured in terms of both the number of annual assignments and the volume of funding, weltwärts is the largest international youth volunteer service in Germany and one of the largest development volunteer services for young adults worldwide. The evaluation focuses its analysis on what volunteers learn, how they are changed by participating in weltwärts, and their civic engagement after they return to Germany. Another question pursued is whether diverse population groups take part in weltwärts and benefit from the programme’s assumed positive effects. The evaluation follows a programme-theory-based approach and implements a mixed-methods design. The core of the methodology is a quasi-experimental design based on cross-sectional surveys of volunteers and of a representative demographic sample of the weltwärts target group. This procedure enables reliable capture of data on the volunteers’ learning and the ways in which they are changed. Group discussions were also held in which volunteers’ voices were heard. Furthermore, members of the volunteers’ families and friends and representatives of the sending organisations were surveyed by means of online questionnaires. Finally, expert interviews and analyses of secondary data and documents were conducted

Our extended senses, tools, technologies, through the ages, have been closed systems incapable of interplay or collective awareness. Now, in the electric age, the very instantaneous nature of co-existence among our technological instruments has created a crisis quite new in human history. Our extended faculties and senses now constitute a single field of experience which demands that they become collectively conscious. Our technologies, like our private senses, now demand an interplay and ratio that makes rational co-existence possible. As long as our technologies were as slow as the wheel or the alphabet or money, the fact that they were separate, closed systems was socially and psychically supportable. This is not true now when sight and sound and movement are simultaneous and global in extent. (McLuhan 1962, p.5, emphasis in original)Over forty years later, the seamless interplay that McLuhan demanded between our technologies is still barely visible. McLuhan’s predictions of the spread, and increased importance, of electronic media have of course been borne out, and the worlds of business, science and knowledge storage and transfer have been revolutionised. Yet the integration of electronic systems as open systems remains in its infancy.Advanced Knowledge Technologies (AKT) aims to address this problem, to create a view of knowledge and its management across its lifecycle, to research and create the services and technologies that such unification will require. Half way through its sixyear span, the results are beginning to come through, and this paper will explore some of the services, technologies and methodologies that have been developed. We hope to give a sense in this paper of the potential for the next three years, to discuss the insights and lessons learnt in the first phase of the project, to articulate the challenges and issues that remain.The WWW provided the original context that made the AKT approach to knowledge management (KM) possible. AKT was initially proposed in 1999, it brought together an interdisciplinary consortium with the technological breadth and complementarity to create the conditions for a unified approach to knowledge across its lifecycle. The combination of this expertise, and the time and space afforded the consortium by the IRC structure, suggested the opportunity for a concerted effort to develop an approach to advanced knowledge technologies, based on the WWW as a basic infrastructure.The technological context of AKT altered for the better in the short period between the development of the proposal and the beginning of the project itself with the development of the semantic web (SW), which foresaw much more intelligent manipulation and querying of knowledge. The opportunities that the SW provided for e.g., more intelligent retrieval, put AKT in the centre of information technology innovation and knowledge management services; the AKT skill set would clearly be central for the exploitation of those opportunities.The SW, as an extension of the WWW, provides an interesting set of constraints to the knowledge management services AKT tries to provide. As a medium for the semantically-informed coordination of information, it has suggested a number of ways in which the objectives of AKT can be achieved, most obviously through the provision of knowledge management services delivered over the web as opposed to the creation and provision of technologies to manage knowledge.AKT is working on the assumption that many web services will be developed and provided for users. The KM problem in the near future will be one of deciding which services are needed and of coordinating them. Many of these services will be largely or entirely legacies of the WWW, and so the capabilities of the services will vary. As well as providing useful KM services in their own right, AKT will be aiming to exploit this opportunity, by reasoning over services, brokering between them, and providing essential meta-services for SW knowledge service management.Ontologies will be a crucial tool for the SW. The AKT consortium brings a lot of expertise on ontologies together, and ontologies were always going to be a key part of the strategy. All kinds of knowledge sharing and transfer activities will be mediated by ontologies, and ontology management will be an important enabling task. Different applications will need to cope with inconsistent ontologies, or with the problems that will follow the automatic creation of ontologies (e.g. merging of pre-existing ontologies to create a third). Ontology mapping, and the elimination of conflicts of reference, will be important tasks. All of these issues are discussed along with our proposed technologies.Similarly, specifications of tasks will be used for the deployment of knowledge services over the SW, but in general it cannot be expected that in the medium term there will be standards for task (or service) specifications. The brokering metaservices that are envisaged will have to deal with this heterogeneity.The emerging picture of the SW is one of great opportunity but it will not be a wellordered, certain or consistent environment. It will comprise many repositories of legacy data, outdated and inconsistent stores, and requirements for common understandings across divergent formalisms. There is clearly a role for standards to play to bring much of this context together; AKT is playing a significant role in these efforts. But standards take time to emerge, they take political power to enforce, and they have been known to stifle innovation (in the short term). AKT is keen to understand the balance between principled inference and statistical processing of web content. Logical inference on the Web is tough. Complex queries using traditional AI inference methods bring most distributed computer systems to their knees. Do we set up semantically well-behaved areas of the Web? Is any part of the Web in which semantic hygiene prevails interesting enough to reason in? These and many other questions need to be addressed if we are to provide effective knowledge technologies for our content on the web

Africa and the International Criminal Court: Behind the Backlash and Toward Future Solutions

Fifteen years into its operation as the preeminent international institution charged with the prosecution of the most serious international crimes, the International Criminal Court (ICC) has faced and continues to face intense backlash from the African continent. Once the Court’s most fervent advocates, many African leaders now lambast the ICC. In recent months, three African countries and the African Union en masse have attempted withdrawal from the Court, thus pushing the ICC-Africa relationship into the international spotlight as a topic of acute global interest. This paper seeks to explore the critiques behind this backlash through both a historical and present-day lens, as well as from the perspectives of African leaders, victims-locals, and civil society actors. In doing so, it investigates historical critiques of the ICTY and ICTR, concerns raised during the Rome Statute negotiations, current African leader perspectives as viewed through the case studies of Darfur, Kenya, Uganda, and the AU-ICC relationship, and present African victim-local and civil society opinions of the Court. By understanding the current and multi-faceted African opposition to the ICC and such criticisms’ historical roots, as well as the pockets of hope for the Court within Africa, this analysis reveals the ICC’s main challenges in its relationship with the African continent. With such hurdles unveiled, the ICC can pursue several strategies, located primarily on the state and individual levels, in its endeavor to address these important critiques and regain African support

Multimodal Definition: The Multiplication of Meaning in Electronic Dictionaries

With the popularity of electronic dictionaries, multimodality plays an increasingly important role in lexicography. To broaden the horizons of e-dictionary definitions, this article argues for the establishment of a new term, multimodal definition, as a key component of multimodal lexicography. This term integrates verbal definitions and the complementary multimodal resources from a holistic viewpoint of meaning. In a multimodal definition, a dynamic meaning ecology can be formed, with two critical variables functioning, (semiotic) mode selection and intermodal synergy. In this ecology, meaning expressed verbally can be multiplied in four dimensions: content, form, space and time. Future directions for research are discussed, including dictionary user studies and multimodal corpora. The findings of this article shed light on the construction of a theoretical model for e-lexicography which remains an urgent task in the ongoing digital revolution.Keywords: Multimodality, multimodal definition, multimodal lexicography, e-dictionary, mode selection, intermodal synergy

The place of the humanities in today’s knowledge society

Over the past four decades, the humanities have been subject to a progressive devaluation within the academic world, with early instances of this phenomenon tracing back to the USA and the UK. There are several clues as to how the university has generally been placing a lower importance on these fields, such as through the elimination of courses or even whole departments. It is worth mentioning that this discrimination against humanities degrees is indirect in nature, as it is in fact mostly the result of the systematic promotion of other fields, particularly, for instance, business management. Such a phenomenon has nonetheless resulted in a considerable reduction in the percentage of humanities graduates within a set of 30 OECD countries, when compared to other areas. In some countries, a decline can even be observed in relation to their absolute numbers, especially with regards to doctorate degrees. This article sheds some light on examples of international political guidelines, laid out by the OECD and the World Bank, which have contributed to this devaluation. It takes a look at the impacts of shrinking resources within academic departments of the humanities, both inside and outside of the university, while assessing the benefits and value of studying these fields. A case is made that a society that is assumed to be ideally based on knowledge should be more permeable and welcoming to the different and unique disciplines that produce it, placing fair and impartial value on its respective fields.info:eu-repo/semantics/publishedVersio

The India MPA Workshop Proceedings. Social Dimensions of Marine Protected Areas Implementation in India: do Fishing Communities Benefit? 21-22 January 2009, IMAGE Auditorium, Chennai, India

In the current context of natural resource management, marine protected areas (MPAs) are being widely propagated as an important tool for the conservation of marine and fisheries resources. The International Collective in Support of Fishworkers (ICSF) recently undertook a series of studies on MPAs in India to highlight the various legal, institutional, policy and livelihoods issues that confront fishing and coastal communities. In order to discuss the findings of these case studies and to suggest proposals for livelihood-sensitive conservation and management of coastal and fisheries resources through participatory processes, ICSF organized a two-day workshop on ‘Social Dimensions of Marine Protected Area Implementation in India: Do Fishing Communities Benefit?’ at Chennai on 21-22 January 2009. This publication—the India MPA Workshop Proceedings—contains the prospectus of the workshop, a report of the proceedings and the consensus statement that was reached by organizations and individuals who particapated in the workshop. This publication will be useful for fishworkers, non-governmental organizations, policymakers, trade unions, researchers and others interested in natural resource management and coastal and fishing communities
