Deploying New Perspectives of Network Organizations for Chronic Diseases’ Integrated Management
Authors: Bonacci Isabella , Tamburis Oscar
Published: September 2010

The social frame of healthcare organizations in Europe (and in particular in the Italian Public Sector), as a combination of relational, formal and informal aspects, is one of their most relevant sources of complexity, which leads to different approaches about decisional, clinical and organizational processes (Cicchetti, 2004). These issues have been enlightened as well by the increasing social incidence of chronic-degenerative pathologies, such as Diabetes Mellitus type 2. In this regard, the Italian national e-government strategy has first pointed out the need for paths of integration and interoperability among information systems to ensure a safe exchange of information (CNIPA, 2008). The activity of “integrated design” of information flows between doctors and patients allows the creation and development of reticular organizational forms in which many non contiguous actors work at the same time on the diagnosis and care process. This paper shows how the adoption of the Social Network Analysis (SNA), as theoretical and methodological perspective that emphasizes the social reality as reticular framework (Moreno, 1987), can provide an innovative approach for the study of the “pathology networks” and the “integrated management” of Diabetes Mellitus type 2, where ICT solutions are (or are about to be) currently involved.
Understanding Expectations, Perceptions and Satisfaction Levels of Customers of Military Engineer Services in India
Authors: Bansal Anand Parkash , Nagadevara Vishnuprasad
Published: September 2010

Customer satisfaction and client orientation concepts are needed in all service providing organisations, including those engaged in construction and infrastructure provision within the public sector where the public perception about their services is at its lowest. This study measures the expectations and perceptions of various service elements among clients of Military Engineer Services (MES) in India. Customers’ survey mode was used to measure the expectations, perception, importance and satisfaction. The perceived quality of services provided by this department was measured with SERVQUAL instrument on selected attributes using the Gap approach for identifying priorities. Additionally, this study also examines the influence of demographic characteristics of clients on expectations and perceptions of the clients. The results can be used by similar organisations for cultural and structural change to increase accountability and performance, in which the results indicate that the three most important dimensions in the order of importance among the clients of MES are tangibles, responsiveness and reliability.
Key Challenges in the Design of Learning Technology Standards
Authors: Cooper Adam R.
Published: September 2010

This paper considers key challenges that learning technology standards must take into account: the inherent connectedness of the information and complexity as a cause of emergent behavior. Some of the limitations of historical approaches to information systems and standards development are briefly considered with generic strategies to tackle complexity and system adaptivity. A consideration of the facets of interoperability—organizational, syntactic and semantic—leads to an outline of a strategy for dealing with environmental complexity in the learning technology standards domain.
Building Tag-Aware Groups for Music High-Order Ranking and Topic Discovery
Authors: Rafailidis Dimitrios , Nanopoulos Alexandros , Manolopoulos Yannis
Published: September 2010

In popular music information retrieval systems, users have the opportunity to tag musical objects to express their personal preferences, thus providing valuable insights about the formulation of user groups/communities. In this article, the authors focus on the analysis of social tagging data to reveal coherent groups characterized by their users, tags and music objects (e.g., songs and artists), which allows for the expression of discovered groups in a multi-aspect way. For each group, this study reveals the most prominent users, tags, and music objects using a generalization of the popular web-ranking concept in the social data domain. Experimenting with real data, the authors’ results show that each Tag-Aware group corresponds to a specific music topic, and additionally, a three way ranking analysis is performed inside each group. Building Tag-Aware groups is crucial to offer ways to add structure in the unstructured nature of tags.
Robust Duplicate Detection of 2D and 3D Objects
Authors: Vajda Peter , Ivanov Ivan , Goldmann Lutz , Lee Jong-Seok , Ebrahimi Touradj
Published: September 2010

In this paper, the authors analyze their graph-based approach for 2D and 3D object duplicate detection in still images. A graph model is used to represent the 3D spatial information of the object based on the features extracted from training images to avoid explicit and complex 3D object modeling. Therefore, improved performance can be achieved in comparison to existing methods in terms of both robustness and computational complexity. Different limitations of this approach are analyzed by evaluating performance with respect to the number of training images and calculation of optimal parameters in a number of applications. Furthermore, effectiveness of object duplicate detection algorithm is measured over different object classes. The authors’ method is shown to be robust in detecting the same objects even when images with objects are taken from different viewpoints or distances.

The authors’ approach is evaluated based on a real world scenario of challenging video data of archive documentaries. In this paper, the performed experiments aim at the evaluation of the performance of established shot boundary detection algorithms, the influence of keyframe selection, and feature representation.
Multi-Label Classification Method for Multimedia Tagging
Authors: Ma Aiyesha , Sethi Ishwar , Patel Nilesh
Published: September 2010

Community tagging offers valuable information for media search and retrieval, but new media items are at a disadvantage. Automated tagging may populate media items with few tags, thus enabling their inclusion into search results. In this paper, a multi-label decision tree is proposed and applied to the problem of automated tagging of media data. In addition to binary labels, the proposed Iterative Split Multi-label Decision Tree (IS-MLT) is easily extended to the problem of weighted labels (such as those depicted by tag clouds). Several datasets of differing media types show the effectiveness of the proposed method relative to other multi-label and single label classifier methods and demonstrate its scalability relative to single label approaches.Keywords: Automated Multimedia Tagging; Community Tagging; Multi-label Classification; Multi-label Decision Tree; Pattern Classification
Robust Design of Power Distribution Systems Using an Enhanced Multi-Objective Genetic Algorithm
Authors: Taroco Cristiane G. , Carrano Eduardo G. , Neto Oriane M.
Published: September 2010

The growing importance of electric distribution systems justifies new investments in their expansion and evolution. It is well known in the literature that optimization techniques can provide better allocation of the financial resources available for such a task, reducing total installation costs and power losses. In this work, the NSGA-II algorithm is used for obtaining a set of efficient solutions with regard to three objective functions, that is cost, reliability, and robustness. Initially, a most likely load scenario is considered for simulation. Next, the performances of the solutions achieved by the NSGA-II are evaluated under different load scenarios, which are generated by means of Monte Carlo Simulations. A Multiobjective Sensitivity Analysis is performed for selecting the most robust solutions. Finally, those solutions are submitted to a local search algorithm to estimate a Pareto set composed of just robust solutions only.
Fuzzy Multi-Choice Goal Programming for Supplier Selection
Authors: Chang Ching-Ter , Ku Cheng-Yuan , Ho Hui-Ping
Published: September 2010

Supplier selection decision is an important issue of purchasing management in supply chain management involving multiple objectives; however, it is difficult to solve because objectives are often conflicting in nature. This study integrates multi-choice goal programming (MCGP) and fuzzy approaches as decision aids to help decision makers to choose better suppliers by considering multiple aspiration levels and vague goal relations. According to the function of multiple aspirations provided by the fuzzy MCGP (FMCGP), decision makers can set fuzzy relations among multiple supplier goals with linguistic quantifiers according to their different strategies. Also, decision makers can define the membership function for each linguistic quantifier to describe their ambiguous selection preference in supplier selection. With the FMCGP method, decision makers can obtain the order quantities for suitable suppliers based on different organizations’ supply chain strategies. To demonstrate the usefulness of the proposed method, a real-world case of a Liquid Crystal Display (LCD) monitor and acrylic sheet manufacturer is presented.
Automatic Real-Time River Traffic Monitoring Based on Artificial Vision Techniques
Authors: Iocchi Luca , Novelli Luca , Tombolini Luigi , Vianello Michele
Published: September 2010

Artificial vision techniques derived from computer vision and autonomous robotic systems have been successfully employed for river traffic monitoring and management. For this purpose, ARGOS and HYDRA systems have been developed by Achimedes Logica in collaboration with Sapienza University of Rome under the EU initiatives URBAN and MOBILIS for the monitoring of the boat traffic in Venice on the Gran Canal and the harbour area. These advanced systems provide an efficient automatic traffic monitoring to guarantee navigation safety and regular flow while producing and distributing information about the traffic. The systems are based on the processing of digital images that are gathered by survey cell stations distributed throughout the supervised area providing a visual platform on which the system displays recent and live traffic conditions in a synthetic way similar to radar view. ARGOS and HYDRA systems are programmed to automatically recognize and notice situations of great interest in whatever sea or land-targeted security applications including environmental, perimeter, and security control. This article describes the wide spectrum of applications of these two systems, that is, monitoring traffic and automatically tracking position, speed and direction of all vehicles.
CONFU
Authors: Dai Huning , Murphy Christian , Kaiser Gail
Published: September 2010

Many software security vulnerabilities only reveal themselves under certain conditions, that is, particular configurations and inputs together with a certain runtime environment. One approach to detecting these vulnerabilities is fuzz testing. However, typical fuzz testing makes no guarantees regarding the syntactic and semantic validity of the input, or of how much of the input space will be explored. To address these problems, the authors present a new testing methodology called Configuration Fuzzing. Configuration Fuzzing is a technique whereby the configuration of the running application is mutated at certain execution points to check for vulnerabilities that only arise in certain conditions. As the application runs in the deployment environment, this testing technique continuously fuzzes the configuration and checks “security invariants’’ that, if violated, indicate vulnerability. This paper discusses the approach and introduces a prototype framework called ConFu (CONfiguration FUzzing testing framework) for implementation. Additionally, the results of case studies that demonstrate the approach’s feasibility are presented along with performance evaluations.
Agile Software Development
Authors: Nicolaysen Torstein , Sassoon Richard , Line Maria B. , Jaatun Martin Gilje
Published: September 2010

In this article, the authors contrast the results of a series of interviews with agile software development organizations with a case study of a distributed agile development effort, focusing on how information security is taken care of in an agile context. The interviews indicate that small and medium-sized agile software development organizations do not use any particular methodology to achieve security goals, even when their software is web-facing and potential targets of attack. This case study confirms that even in cases where security is an articulated requirement, and where security design is fed as input to the implementation team, there is no guarantee that the end result meets the security objectives. The authors contend that security must be built as an intrinsic software property and emphasize the need for security awareness throughout the whole software development lifecycle. This paper suggests two extensions to agile methodologies that may contribute to ensuring focus on security during the complete lifecycle.
Semantic Search on Unstructured Data
Authors: Kohn Alex , Bry François , Manta Alexander
Published: September 2010

Studies agree that searchers are often not satisfied with the performance of current enterprise search engines. As a consequence, more scientists worldwide are actively investigating new avenues for searching to improve retrieval performance. This paper contributes to YASA (Your Adaptive Search Agent), a fully implemented and thoroughly evaluated ontology-based information retrieval system for the enterprise. A salient particularity of YASA is that large parts of the ontology are automatically filled with facts by recycling and transforming existing data. YASA offers context-based personalization, faceted navigation, as well as semantic search capabilities. YASA has been deployed and evaluated in the pharmaceutical research department of Roche, Penzberg, and results show that already semantically simple ontologies suffice to considerably improve search performance.
An Interdisciplinary Design Project in Second Life
Authors: Triggs Riley , Jarmon Leslie , Villareal Tracy A.
Published: September 2010

Virtual environments can resolve many practical and pedagogical challenges within higher education. Economic considerations, accessibility issues, and safety concerns can all be somewhat alleviated by creating learning activities in a virtual space. Because of the removal of real-world physical limitations like gravity, durability and scope, virtual space allows for an expansion of possibilities and approaches to knowledge transfer and discovery learning and becomes an “environment for information” rich with collaborative possibilities. Experimentation and participation in conceptual as well as applied projects is encouraged for both students and instructors. One of these virtual environments, Second Life, was used in a cross-disciplinary project for the creation of a Marine Science virtual class environment as an assignment for design students at a major southwestern research university in the United States. This paper reports on the findings from a project that utilized Second Life as a medium for enhancing and extending design education using a process of interdisciplinary collaboration.
The Development of a Personal Learning Environment in Second Life
Authors: Andrews Sandra Sutton , Stokrocki Mary , Jannasch-Pennell Angel , DiGangi Samuel A.
Published: September 2010

In this qualitative pilot study, the authors report on curriculum field trials within a personal learning environment (PLE) designed by a collaboration of academic researchers and nonprofit volunteers working together in the virtual world of Second Life. The purpose of the PLE is to provide learners less likely to have access to educational opportunities with a means to create a ‘new life’ in the real world, through a basic web-based curriculum and an advanced Second Life curriculum. Field trials of the Second Life curriculum were held with youth from underserved populations (n=6) to identify participant characteristics that facilitate success with the curriculum. Performance on instructional outcomes was examined in addition to a participatory action research methodology (PAR) that was employed with participants as co-researchers. To protect identities, the authors use a case study approach to track one composite participant/co-researcher through the curriculum.
Interpreting Images of Motherhood: The Contexts and Dynamics of Collective Viewing
Authors: Lomax Helen , Fink Janet
Published: September 2010

Our research is concerned with cultural representations of birth and mothering and, as part of this, we are engaged with debates concerning competing theoretical and methodological approaches to the analysis of visual images. In particular we are interested in how meanings of an image are reflexively produced, managed and negotiated. That is, whether and to what extent interpretation is influenced by personal experience, emotion and memory; the ways in which the context of viewing may mediate meaning; and how the relationship between researcher and research subject may shape the interpretative process. In order to explore such questions, this paper draws on the tape-recorded discussion of a group of women collectively viewing images of new mothers. These included photographs of mothers and their newborns taken by the Dutch photographer Rineke Dijkstra, and photographs of us, the authors, as new mothers, taken by our respective families.

The paper blends the analytic framework of conversation analysis and discursive psychology in order to consider both our own and the discussants’ responses to these photographs as they emerge through the dynamic and discursive process of collective viewing. In addition we consider the significance of our own and the discussants’ biographies and reproductive experiences, as they are made visible in the talk-in-interaction, for the meanings generated by the group's engagement with the photographs. Through this reflexive approach we highlight the significance of the interplay between broader cultural narratives, genres, memories and experiences for the interpretive process and the analytical challenges posed by collective viewings of images in which meanings are discursively situated, negotiated and silenced.
The Work of Repair: Gesture, Emotion and Sensual Knowledge
Authors: Dant Tim
Published: September 2010

As the pressure on limited natural resources and energy increases, so the trend of the consumer society of the twentieth century towards discarding and replacing things that stop working will shift towards recycling and repairing them. This paper contrasts the work of production with the work of repair and argues that the later is an artisanal process in tune with the species being of humans identified by Marx. Amongst the distinctive characteristics of the work of repair are the use of a complex repertoire of gestures, a variable emotional tone and the gathering of sensual knowledge. These distinctively human characteristics are not amenable to systematisation or replication in a machine process. The argument is illustrated with reference to more than sixty years of research on mechanised production in the car industry and a recent study of the work of repairing cars in local garages. Video data – here summarised with still images – is used to show the complex process of the work of repair that is explored in the light of theoretical perspectives from Leroi-Gourhan, Hendrick, and Merleau-Ponty.
Modelling Dimensions of ‘the Social’ in Knowledge Teams: An Operationalisation of Habermas’ Theory of Communicative Action
Authors: Quinlan Elizabeth , Robertson Susan
Published: September 2010

The introduction of knowledge teams, as a new form of work organisation, is one of many institutional transformations associated with the knowledge economy. The research on the effects of this new form of work organisation on the social processes by which knowledge workers exchange, create, and apply knowledge is limited. The research that does exist uses various communication theories to explain the social interactions within knowledge teams. We offer an alternative theoretical framework, based on Habermas’ theory of communicative action. In this paper, we operationalise the theory using dynamic agent-based modelling to perform a series of ‘virtual experiments’ on the temporal dynamics of knowledge exchange within teams. The modelling results are used to critically reflect on the theory and draw conclusions regarding the lifeworld rationalisation within knowledge teams. The paper closes by specifying areas of future work and suggesting that a practical outcome of the completed research agenda will be an evaluation tool to be used by knowledge teams to assess how effective they are at communicating and producing knowledge.

Battles over Biofuels in Europe: NGOs and the Politics of Markets
Authors: Pilgrim Sarah , Harvey Mark
Published: September 2010

In this paper, we argue that a consortium of NGOs has played a significant role in shaping the market for, and restricting the use of, biofuels as an alternative to conventional fuels for road transport in Europe. This paper considers why a number of NGOs (Greenpeace, Oxfam, WWF, RSPB, Friends of the Earth) have chosen to enter the biofuels debate, and how they have variously developed policy, agreed a political campaign, and exercised political influence, in a key area of the world's response to major global climate change: how to reduce the carbon footprint of transport.

We found that in many cases the development of NGO policy has been driven more by narrow political opportunities for influence than by broader and more coherent policy responses to global climate change or economic development, or indeed rigorous assessment of the scientific evidence. The research provides evidence of how NGO policies and lobbying significantly affected biofuel policy changes, review processes, target reductions, and sustainability regulation in the UK and in Europe.

We consider that politically instituted markets, such as the one for biofuels, are examples of the emergence of new forms of governance of capitalist political economies facing a novel and pressing combination of drivers (climate change, energy security, resource constraints, and sustainable land-use). Politically instituted markets open up possibilities for political intervention from non-governmental or party-political actors, in ways that other markets do not. If political shaping of markets by NGOs becomes more widespread, issues of democratic legitimacy and public scrutiny will become ever more pressing.

The paper is based on in-depth interviews with senior scientific directors and policy-makers in five NGOs, and of senior officials in UK government departments and the European Commission (DG Environment and DG Transport and Energy). It forms part of a wider ESRC research project in Brazil, the USA and Europe on the Transition to Sustainable Bioeconomies.

Abstract. As part of the OP3 field study of rainforest atmospheric chemistry, above-canopy fluxes of isoprene, monoterpenes and oxygenated volatile organic compounds were made by virtual disjunct eddy covariance from a South-East Asian tropical rainforest in Malaysia. Approximately 500 hours of flux data were collected over 48 days in April–May and June–July 2008. Isoprene was the dominant non-methane hydrocarbon emitted from the forest, accounting for 80% (as carbon) of the measured emission of reactive carbon fluxes. Total monoterpene emissions accounted for 18% of the measured reactive carbon flux. There was no evidence for nocturnal monoterpene emissions and during the day their flux rate was dependent on both light and temperature. The oxygenated compounds, including methanol, acetone and acetaldehyde, contributed less than 2% of the total measured reactive carbon flux. The sum of the VOC fluxes measured represents a 0.4% loss of daytime assimilated carbon by the canopy, but atmospheric chemistry box modelling suggests that most (90%) of this reactive carbon is returned back to the canopy by wet and dry deposition following chemical transformation. The emission rates of isoprene and monoterpenes, normalised to 30 °C and 1000 μmol m−2 s−1 PAR, were 1.6 mg m−2 h−1 and 0.46mg m−2 h−1 respectively, which was 4 and 1.8 times lower respectively than the default value for tropical forests in the widely-used MEGAN model of biogenic VOC emissions. This highlights the need for more direct canopy-scale flux measurements of VOCs from the world's tropical forests.
Generation of hydrogen peroxide from San Joaquin Valley particles in a cell-free solution
Authors: Shen H. , Barakat A. I. , Anastasio C.
Published: September 2010

Abstract. Epidemiological studies have shown a correlation between exposure to ambient particulate matter (PM) and adverse health effects. One proposed mechanism of PM-mediated health effects is the generation of reactive oxygen species (ROS) – e.g., superoxide (•O2−), hydrogen peroxide (HOOH), and hydroxyl radical (•OH) – followed by oxidative stress. There are very few quantitative, specific measures of individual ROS generated from PM, but this information would help to more quantitatively address the link between ROS and the health effects of PM. To address this gap, we quantified the generation of HOOH by PM collected at an urban (Fresno) and rural (Westside) site in the San Joaquin Valley (SJV) of California during summer and winter from 2006 to 2009. HOOH was quantified by HPLC after extracting the PM in a cell-free, phosphate-buffered saline (PBS) solution with or without 50 μM ascorbate (Asc). Our results show that the urban PM generally generates much more HOOH than the rural PM but that there is no apparent seasonal difference in HOOH generation. In nearly all of the samples the addition of a physiologically relevant concentration of Asc greatly enhances HOOH formation, but a few of the coarse PM samples were able to generate a considerable amount of HOOH in the absence of added Asc, indicating the presence of unknown reductants. Normalized by air volume, the fine PM (PM2.5) generally makes more HOOH than the corresponding coarse PM (PMcf, i.e., 2.5 to 10 μm), primarily because the mass concentration of PM2.5 is much higher than that of PMcf. However, normalized by PM mass, the coarse PM typically generates more HOOH than the fine PM. The amount of HOOH produced by SJV PM is reduced on average by (78±15)% when the transition metal chelator desferoxamine (DSF) is added to the extraction solution, indicating that transition metals play a dominant role in HOOH generation. By measuring calibration curves of HOOH generation from copper, and quantifying copper concentrations in our particle extracts, we find that PBS-soluble copper is primarily responsible for HOOH production by the Fresno PM. Extrapolating our results to expected concentrations of PM-derived HOOH in human lungs suggests that typical daily PM exposures in the San Joaquin Valley are unlikely to cause HOOH-mediated acute health effects, but that very high PM events might lead to cytotoxic levels of pulmonary HOOH.
Studies on Hepatitis C Virus Resistance to Inhibitors in Replicon Systems
Authors: Zhao Yongsen , Huang Mingjun
Published: September 2010

Viruses evolve under selection pressure from a particular antiviral agent, resulting in the emergence of organisms that are not susceptible to the drug. This process is referred to as “virus resistance induction.” While conventional in vitro resistance studies are conducted using infectious viruses, the lack of a robust hepatitis C virus (HCV) infection system in cell culture makes such an approach impossible in this case. Instead, cell lines harboring a self‐replicating HCV RNA (or HCV replicon) are used for this purpose. The protocols detailed in this unit describe methods for studying HCV resistance to inhibitors, including the selection of replicon variants resistant to HCV inhibitors, characterization of these variants for their phenotypes and genotypes, and determination of the role of the mutation(s) identified in their genomes. The results from such studies are not only important for lead identification and confirmation of drug targets, but also aid in monitoring the appearance of resistant variants in clinical settings.

Platinum‐Like Catalytic Behavior of Au+
Authors: Oyama S. Ted , Gaudet Jason , Zhang Wei , Su Dang Sheng , Bando Kyoko K.
Published: September 2010

The catalytic properties of gold catalysts leached with sodium cyanide solutions were investigated for the propylene epoxidation reaction with H2/O2 mixtures. Unexpectedly, the selectivity of the Au/TS‐1 catalysts changed from propylene oxide to propane as a result of the cyanide treatment. Measurements by in situ X‐ray absorption spectroscopy at in situ reaction conditions demonstrated that the active catalyst before leaching consisted of gold in the zero‐valent state, while after the cyanide treatment had gold in the Au+ state. Examination of the catalysts by high resolution transmission electron microscopy revealed the formation of precipitates of a material with lattice spacings corresponding to Na[Au(CN)2]. It is found that leaching with cyanide does not result in positively‐charged gold ions substituting in cation vacancies, as previously thought, but instead produces a gold(I) cyanide precipitate with catalytic hydrogenation properties typical of platinum. These results explain previously reported findings on highly dispersed gold nanoparticles, in which the peripheral atoms are positively charged.
Electronic Tuning of a Carbene Center via Remote Chemical Induction, and Relevant Effects in Catalysis
Authors: César Vincent , Lugan Noël , Lavigne Guy
Published: September 2010

The present report develops the idea that an N‐heterocyclic carbene incorporating a remote anionic functionality—here, a malonate group—as a backbone component of its heterocyclic framework, can be “post‐functionalized” directly from its transition‐metal complexes, upon simple addition of a variety of electrophiles interacting directly with the malonate group in the outer coordination sphere. From a palette of selected electrophilic reagents, it was thus possible to modulate the electronic donor properties of the carbene center over a rather broad range. Both the zwitterionic complex [Rh{malo‐NHC}(cod)] and the cationic derivatives [Rh{malo‐NHCE}(cod)]+ (where “malo‐NHCE” represents the ligand modified by a selected electrophile “E”) were used as pre‐catalysts in two types of catalytic reactions, namely, the polymerization of phenylacetylene and the hydroboration of styrene. The results indicate that, in both cases, the zwitterionic species is by far the best catalyst, whereas a decrease in the ligand donicity induced by the added electrophile results in a concomitant reduction of catalytic activity. Apparent deviations to such a trend in the case of the hydroboration of styrene were rationalized in terms of an interaction between the reactive catecholborane substrate and the remote functionality of the N‐heterocyclic carbene leading to an in situ modification of the nature of the active species. These observations serve as a useful basis to define the scope and limitations of the present conceptual approach in catalysis.
Getting Ring‐Closing Metathesis off the Bench: Reaction‐Reactor Matching Transforms Metathesis Efficiency in the Assembly of Large Rings
Authors: Monfette Sebastien , Eyholzer Markus , Roberge Dominique M. , Fogg Deryn E.
Published: September 2010

Reported is the first study of the influence of reactor configuration on the efficiency of a challenging ring‐closing metathesis (RCM) reaction. With the intention of increasing the generality of RCM scaleup and reducing its dependence on substrate modification, macrocyclization of an unmodified, low effective‐molarity diene was explored using different reactor types, in conjunction with a commercial, homogeneous Grubbs catalyst. Optimized performance is compared for a conventional batch reactor (BR), a continuous plug‐flow reactor (PFR), and a continuous stirred‐tank reactor (CSTR). In the PFR, maximum conversion is achieved most rapidly, but product yields and selectivity are adversely affected by co‐entrapment of ethylene with the catalyst, substrate, and product in the traveling “plug”. Use of the CSTR, in which ethylene is efficiently swept out, affords an order‐of‐magnitude increase in total turnover numbers, and reduces the required catalyst loadings by 25× relative to the BR (to 0.2 mol %), while improving RCM yields and selectivity to quantitative levels. Continuous‐flow methodologies that support liberation of the ethylene co‐product thus show great promise for industrial uptake of RCM.
