Abstract A fatal accident occurred when a right angle gear box on an auger elevator disintegrated freeing the outboard end of a rotating PTO shaft. The tractor, acting as a stationary power source, flailed the PTO shaft which then struck and killed a farmer. No similar occurrences have been reported for the nearly 2000 similar units which have been used for over a decade. This paper studies a number of fundamental failure modes in order to determine which failure modes created the accident. Systematic analysis showed that the accident was caused by unusual misuse of the product. Known safety control concepts do not preclude this unforeseeable event.

This paper investigates adjectival agreement in a group of Middle Welsh native prose texts and a sample of translations from around the end of the Middle Welsh period and the beginning of the Early Modern period. It presents a new methodology, employing tagged historical corpora allowing for consistent linguistic comparison. The adjectival agreement case study tests a hypothesis regarding position and function of adjectives in Middle Welsh, as well as specific semantic groups of adjectives, such as colours or related modifiers. The systematic analysis using an annotated corpus reveals that there are interesting differences between native and translated texts, as well as between individual texts. However, zooming in on our adjectival agreement case study, we conclude that these differences do not correspond to many of our hypotheses or assumptions about how certain texts group together. In particular, no clear split into native and translated texts emerged between the texts in our corpus. This paper thus shows interesting results for both (historical) linguists, especially those working on agreement, and scholars of medieval Celtic philology and translation texts.

The Traveling Salesman Problem

The variation of the traveling salesman problem (TSP) with multiple salesmen (m-TSP) has been studied for many years resulting in diverse solution methods, both exact and heuristic. However, the high difficulty level on finding optimal (or acceptable) solutions has opposed the many efforts of doing so. The proposed method regards a two stage procedure which implies a modified version of the p-Median Problem (PMP) alongside the TSP, making a partition of the nodes into subsets that will be assigned to each salesman, solving it with Branch & Cut (B&C), in the first stage. This is followed by the routing, applying an Ant Colony Optimization (ACO) metaheuristic algorithm to solve a TSP for each subset of nodes. A case study was reviewed, detailing the positioning of five vehicles in strategic places in the Mexican Republic.

Educational research is one of the many fields of knowledge that frequently use case studies as a research method, particularly when applying an interpretive approach. Based on literature reviews and a systematic analysis of current scientific literature, this paper examines the prevalence and characteristics of the case study as a methodology for research on MOOCs. Ninety-two documents were selected from the search results returned by two of the most prestigious scientific databases: Web of Science (WOS) and SCOPUS. Findings showed that (a) even when searching solely for case studies, quantitative research paradigms were more prevalent than interpretive approaches; (b) geographical distribution of these studies was partially biased; (c) case studies were less prevalent in these databases than other empirical investigations on MOOCs; (d) the data collection and data analysis methods most frequently used in the case studies were more aligned with a quantitative approach; and (e) there is still very little instructor-focused research using this methodology. In the light of these findings and their discussion, future directions for research using case study methodology are proposed, given the potential of this method to illustrate certain issues for which other approaches have proved inadequate or insufficient.

Communicating knowledge about energy transition is a challenge of sustainable development. Serious games are a possible approach to explain complex relationships and present them to citizens. This paper discusses the development process of the serious board game “Changing the Game—Neighbourhood”. Therefore, this paper describes our approach of developing a serious game with co-designers in four phases and illustrates the process using an example. Doing so, the paper focus on two central challenges: (1) How can a serious game be developed for the energy transition, which keeps a balance between learning and playability? (2) How can co-design contribute to the development of a serious game? We found out that the use of prototypes and the influence of different stakeholders as informants, co-designers, and testers were crucial for the expansion of the learning content, the improvement of the gameplay, and the balancing of the difficulty level. In addition, the energy transition at the neighborhood level appeared to be a suitable topic for a serious game. During the development process, the serious game was already used for citizen participation, involving about 120 participants in 15 workshops.

AbstractRecent literature suggests that direct national access to multilateral climate funds could promote climate change adaptation investment that focuses more on the needs of vulnerable local communities when compared to indirect access through multilateral agencies. However, there has been no systematic comparative assessment of the level of community focus of direct-access and indirect-access projects. The lack of a standardized methodology to assess the level of community-focused adaptation has also constrained such comparison. To address this gap, this paper proposes a new framework to assess the level of community focus in adaptation projects, using a combination of financial, participatory, devolutionary, and design for policy adoption and replicability criteria. Using the Adaptation Fund (AF) as a case study, we apply the framework to systematically assess 63 projects approved by the Fund as of May 2017, comprising 22 direct-access and 41 indirect-access projects. We find that direct-access projects are more community-focused than indirect-access projects because they exhibit higher community-oriented financial, participatory, and devolutionary characteristics. We find no difference between the direct-access and indirect-access projects with regard to how they are designed to promote policy adoption and replicability of AF project-financed adaptation actions through policy and geographical mainstreaming. Our findings contribute to an improved understanding of the pattern of adaptation investment that takes place in developing countries with the support of international adaptation finance under both access modalities. The proposed assessment framework could also inform the development of a standardized methodology to track the delivery of international adaptation finance to the community level.

The analysis of precedents represents a significant point of departure for design processing. By applying a language/ design analogy, this research introduces a reverse-engineering tool that helps guide the systematic analysis of architectural precedents. The visual tool consists of four main layers: the morphological, the semantic, the semiotic, and the pragmatic. To test the tool?s applicability, a prominent precedent from the Palladian designs is analyzed as a case study. By developing the tool and demonstrating its applicability for the analysis of the underlying regulatory and formative principles of the Palladian design, this paper aims to contribute to the knowledge of architectural design by introducing an analytical tool for decoding and externalizing the design language. This tool can be added to the existing toolbox of designers, and it can help reveal new insights into the multi-layered compositional language of precedents and their underlying architectonics. The findings related to the tool?s applicability and the compositional language of the Palladian design and its associative meanings and connotations are explained, discussed and illustrated by diagrams.
