<div class="page" title="Page 1"><div class="layoutArea"><div class="column"><p><span>In this workshop, we reflect on and share the fun and frustrations of working in interdisciplinary research. We ask participants to openly reflect on their experiences of interdisciplinarity. What approaches have worked and what have failed? In addition to identifying phenomena, we aim to sketch out the next decade of interdisciplinary research in computing, especially in HCI. The third paradigm of Human-Computer Interaction focuses on the qualitative aspects of use experience and the situatedness of technologies. This new orientation has drawn in researchers from various other research and arts backgrounds and traditions, including the social sciences, architecture and industrial design among others. Therefore, we consider this third paradigm to be inherently interdisciplinary. Through workshop participants’ reflection of their own experiences, we strive to identify the common problems and pitfalls of interdisciplinary research, and to celebrate successes, as well as share best practices. </span></p></div></div></div>

<div class="page" title="Page 1"><div class="layoutArea"><div class="column"><p><span>This one-day workshop seeks to reflect on the notion of fab- rication in both personal and industrial contexts. Although these contexts are very distinct in their economical and polit- ical vision, they share important characteristics (e.g., users interacting with specific fabrication equipment and tools). The workshop topic spans from personal fabrication to (au- tomated) production, from applied to theoretical considera- tions, from user requirements to design as a crafting practice. We will address changes in production that affect humans, e.g., from mass production to Do-It-Yourself (DIY) produc- tion, in order to discuss findings and lessons learned for in- dividual and collective production workplaces of the future. We aim to explore the intersections between different dimen- sions and processes of production ranging all the way from hobbyist to professional making. Furthermore, the workshop will critically reflect on current developments and their conse- quences on personal, societal, and economical levels includ- ing questions of the reorganization of work and labor, inno- vation cultures, and politics of participation. </span></p></div></div></div>

Straight-Line Triangle Representations via Schnyder Labelings
Authors: Aerts Nieke , Felsner Stefan 
Published: October 2015

A straight-line triangle representation (SLTR) of a planar graph is a straight-line drawing such that all the faces including the outer face are triangles. Such a drawing can be viewed as a tiling of a triangle with triangles where the input graph is the skeletal structure. A characterization based on flat angle assignments, i.e., selections of angles of the graph that are of size π in the representation, has been presented in earlier work. The drawback of this characterization of SLTRs is that we have no efficient algorithm for testing whether a given graph admits a flat angle assignment that fulfills the conditions. In this paper we present a new characterization based on Schnyder woods. For graphs with few Schnyder woods there exists a polynomial algorithm to check whether the conditions of this characterization are satisfied. However, there are planar 3-connected graphs on n vertices, which have 3.209n Schnyder woods. We also present a translation of the new characterization into a 2-commodity flow problem. Deciding whether a 2-commodity flow problem has an integral solution is known to be NP-complete. Hence, it is still open to decide whether the recognition of graphs that admit a straight line triangle representation is polynomially tractable.
Clercs progressistes et néonationalisme acadien, 1966-1982
Authors: Volpé Philippe 
Published: October 2015

La période de « modernisation institutionnelle » et d’élaboration du néonationalisme acadien qu’est celle des années 1960-1980 a jusqu’ici été présentée dans l’historiographie comme celle d’une sécularisation de la référence acadienne et du corps militant. Une telle simplification fausse toutefois le portrait d’ensemble. Par l’étude d’associations et de mouvements constituant le creuset idéologique du néonationalisme acadien, l’auteur met en évidence l’apport non négligeable de clercs à la modulation de la référence acadienne et à ses mobilisations. Des fondements personnalistes du néonationalisme acadien au moment autonomiste, en passant par le moment des luttes socioéconomiques, il montre qu’un important nombre de clercs, revoyant leur philosophie chrétienne qu’ils croisent à des idées progressistes, y prennent part au point d’en devenir, dans certains cas, les chefs de file.

IntroductionIn recent years children and adolescents have emerged as a priority for HIV prevention and care services. We conducted a systematic review to investigate the acceptability, yield and prevalence of HIV testing and counselling (HTC) strategies in children and adolescents (5 to 19 years) in sub‐Saharan Africa.MethodsAn electronic search was conducted in MEDLINE, EMBASE, Global Health and conference abstract databases. Studies reporting on HTC acceptability, yield and prevalence and published between January 2004 and September 2014 were included. Pooled proportions for these three outcomes were estimated using a random effects model. A quality assessment was conducted on included studies.Results and discussionA total of 16,380 potential citations were identified, of which 21 studies (23 entries) were included. Most studies were conducted in Kenya (n=5) and Uganda (n=5) and judged to provide moderate (n=15) to low quality (n=7) evidence, with data not disaggregated by age. Seven studies reported on provider‐initiated testing and counselling (PITC), with the remainder reporting on family‐centred (n=5), home‐based (n=5), outreach (n=5) and school‐linked HTC among primary schoolchildren (n=1). PITC among inpatients had the highest acceptability (86.3%; 95% confidence interval [CI]: 65.5 to 100%), yield (12.2%; 95% CI: 6.1 to 18.3%) and prevalence (15.4%; 95% CI: 5.0 to 25.7%). Family‐centred HTC had lower acceptance compared to home‐based HTC (51.7%; 95% CI: 10.4 to 92.9% vs. 84.9%; 95% CI: 74.4 to 95.4%) yet higher prevalence (8.4%; 95% CI: 3.4 to 13.5% vs. 3.0%; 95% CI: 1.0 to 4.9%). School‐linked HTC showed poor acceptance and low prevalence.ConclusionsWhile PITC may have high test acceptability priority should be given to evaluating strategies beyond healthcare settings (e.g. home‐based HTC among families) to identify individuals earlier in their disease progression. Data on linkage to care and cost‐effectiveness of HTC strategies are needed to strengthen policies.

Published: October 2015

Abstract
Marine protected areas in the sampling sites have been established 8-13 years ago. This study was conducted to have a baseline information on the diversity, density and biomass of coral reef fishes inside and outside the five marine protected areas (MPAs) of Casay, Argao; Cawayan, Dalaguete; Daan-Lungsod Guiwang, Alcoy; North Granada, Boljoon and Sta. Cruz, Ronda (Control). Coral reef fishes in the MPAs were identified using Fish Visual Census Method. Results of the t-test showed that the mean diversity (fish species/250m2) of target and non-target fish species found in areas inside and outside the MPAs were significantly different. In terms of target species, the inside and outside density showed no significant difference. Similarly, density (ind./1,000m2) of non-target species inside and outside also showed no significant difference. This is an indication that fish density inside and outside the MPAs were more or less of the same condition. The mean biomass (kg/1,000m2) of target species inside and outside the MPAs showed a significant difference in contrast with non-target species inside and outside the MPAs which showed a no significant difference. Higher biomass of target fish species belonging to family Caesonidae (fusiliers) and Scaridae (parrotfishes) were commonly observed inside the MPAs. Results showed that fish species were more diverse with higher density and biomass inside the MPAs than the outside area. However, fish diversity and density were contributed mostly by non-target species. Hence, the need for a long-term protection and a well-managed MPA to improve fish population in terms of diversity, density and biomass specifically, target fish species.
Identifying cryptotephra units using correlated rapid, nondestructive methods: VSWIR spectroscopy, X‐ray fluorescence, and magnetic susceptibility

Published: October 2015

AbstractUnderstanding the frequency, magnitude, and nature of explosive volcanic eruptions is essential for hazard planning and risk mitigation. Terrestrial stratigraphic tephra records can be patchy and incomplete due to subsequent erosion and burial processes. In contrast, the marine sedimentary record commonly preserves a more complete historical record of volcanic activity as individual events are archived within continually accumulating background sediments. While larger tephra layers are often identifiable by changes in sediment color and/or texture, smaller fallout layers may also be present that are not visible to the naked eye. These cryptotephra are commonly more difficult to identify and often require time‐consuming and destructive point counting, petrography, and microscopy work. Here we present several rapid, nondestructive, and quantitative core scanning methodologies (magnetic susceptibility, visible to shortwave infrared spectroscopy, and XRF core scanning) which, when combined, can be used to identify the presence of increased volcaniclastic components (interpreted to be cryptotephra) in the sedimentary record. We develop a new spectral parameter (BDI1000VIS) that exploits the absorption of the 1 µm near‐infrared band in tephra. Using predetermined mixtures, BDI1000VIS can accurately identify tephra layers in concentrations >15–20%. When applied to the upper ∼270 kyr record of IODP core U1396C from the Caribbean Sea, and verified by traditional point counting, 29 potential cryptotephra layers were identified as originating from eruptions of the Lesser Antilles Volcanic Arc. Application of these methods in future coring endeavors can be used to minimize the need for physical disaggregation of valuable drill core material and allow for near‐real‐time recognition of tephra units, both visible and cryptotephra.
Friction weakening in granular flows deduced from seismic records at the Soufrière Hills Volcano, Montserrat

Published: October 2015

AbstractAccurate modeling of rockfalls and pyroclastic flows is still an open issue, partly due to a lack of measurements related to their dynamics. Using seismic data from the Soufrière Hills Volcano, Montserrat, and granular flow modeling, we show that the power laws relating the seismic energy Es to the seismic duration ts and relating the loss of potential energy ΔEp to the flow duration tf are very similar, like the power laws observed at Piton de la Fournaise, Reunion Island. Observations showing that tf≃ts suggest a constant ratio Es/ΔEp≃10−5. This similarity in these two power laws can be obtained only when the granular flow model uses a friction coefficient that decreases with the volume transported. Furthermore, with this volume‐dependent friction coefficient, the simulated force applied by the flow to the ground correlates well with the seismic energy, highlighting the signature of this friction weakening effect in seismic data.

Published: October 2015

AbstractThe seasonal sea level variations observed from tide gauges over 1900–2013 and gridded satellite altimeter product AVISO over 1993–2013 in the northwest Pacific have been explored. The seasonal cycle is able to explain 60–90% of monthly sea level variance in the marginal seas, while it explains less than 20% of variance in the eddy‐rich regions. The maximum annual and semiannual sea level cycles (30 and 6 cm) are observed in the north of the East China Sea and the west of the South China Sea, respectively. AVISO was found to underestimate the annual amplitude by 25% compared to tide gauge estimates along the coasts of China and Russia. The forcing for the seasonal sea level cycle was identified. The atmospheric pressure and the steric height produce 8–12 cm of the annual cycle in the middle continental shelf and in the Kuroshio Current regions separately. The removal of the two attributors from total sea level permits to identify the sea level residuals that still show significant seasonality in the marginal seas. Both nearby wind stress and surface currents can explain well the long‐term variability of the seasonal sea level cycle in the marginal seas and the tropics because of their influence on the sea level residuals. Interestingly, the surface currents are a better descriptor in the areas where the ocean currents are known to be strong. Here, they explain 50–90% of interannual variability due to the strong links between the steric height and the large‐scale ocean currents.
Influence of Wall Effects on Filter Upscaling during Solid‐Liquid Filter Tests
Authors: Gursch Johannes , Giner Rafael , Krammer Gernot 
Published: October 2015

AbstractIndustrial solid‐liquid filtration units are upscaled based on laboratory tests, often by a resistance meter. Wall or boundary effects are more pronounced during lab tests compared with full‐scale units where these effects might be negligible. Thus, simply using area‐specific rates from lab tests may lead to a significant upscaling error. Intentional alterations of wall lengths and filtration areas are performed to allow quantitative description of this effect. Smaller area and longer wall length result in faster cake buildup as well as higher air consumption during subsequent cake drying. This indicates that the permeability close to the walls is different. Extrapolation towards negligible specific wall areas is used to improve upscaling calculations.
Electrochemical and Spectroelectrochemical Properties of Free‐Base Pyridyl‐ and N‐Alkyl‐4‐Pyridylporphyrins in Nonaqueous Media

Published: October 2015

AbstractTwelve structurally related pyridyl and meso‐N‐methylpyridylporphyrin derivatives are investigated electrochemically in different nonaqueous media. The UV/Vis spectrum of each newly investigated porphyrin was measured before and after electroreduction and, based on this data, the site of electron transfer is proposed. An interaction occurs between the meso‐pyridyl or meso‐N‐alkyl‐4‐pyridyl substituents and the porphyrin π‐ring system, the magnitude of which depends upon the number of linked pyridyl or N‐alkyl‐4‐pyridyl groups in the compound, the solvent, the supporting electrolyte, and/or other anions added to the solution.

The strategic viability of this methodology has been demonstrated through the total synthesis of cyclotryptamine alkaloids (−)‐ and (+)‐folicanthine (1 a) and the formal total synthesis of (−)‐chimonanthine (1 b), (+)‐calycanthine (1 c), and (−)‐ditryptophenaline (1 d).
Synthesis of 8‐Aminoquinolines by Using Carbamate Reagents: Facile Installation and Deprotection of Practical Amidating Groups
Authors: Gwon Donghyeon , Hwang Heejun , Kim Hye Kyung , Marder Seth R. , Chang Sukbok 
Published: October 2015

AbstractDescribed herein is the development of practical routes to 8‐aminoquinolines by using readily installable and easily deprotectable amidating reagents. Two scalable procedures were optimized under RhIII‐catalyzed conditions: i) the use of pre‐generated chlorocarbamates and ii) a two‐step one‐pot process that directly employs carbamates. Both approaches are highly convenient for the gram‐scale synthesis of 8‐aminoquinolines under mild conditions. Facile deprotection of the synthetically versatile amidating groups was achieved under the Pd‐catalyzed transfer hydrogenation conditions with simultaneous deoxygenation of quinoline N‐oxides, thus yielding 8‐aminoquinolines in excellent overall efficiency.

The formation of this compound was investigated by spectroscopic and theoretical methods, revealing an unusual ring expansion reaction. The title compound was fully characterized by experimental and computational methods.
Cloud service QoS prediction via exploiting collaborative filtering and location‐based data smoothing
Authors: Tang Mingdong , Zhang Tingting , Liu Jianxun , Chen Jinjun 
Published: October 2015

SummaryTo assess the quality of services (QoS) in service selection, collaborative service QoS prediction has recently garnered increasing attention. They focus on exploring the historical QoS information generated by interactions between users and services. However, they may suffer from the data sparsity issue because interactions between users and services are usually sparse in real scenarios. They also seldom consider the network environments of users and services, which surely will affect cloud service QoS. To address the data sparsity issue and improve the QoS prediction accuracy, the following paper proposes a collaborative QoS prediction method with location‐based data smoothing. The method first computes neighborhoods of users and services based on their locations which provide a basis for data smoothing. It then combines user‐based and service‐based collaborative filtering techniques to make QoS predictions. Experiments conducted using a real service invocation dataset validate the performance of the proposed QoS prediction method. Copyright © 2015 John Wiley & Sons, Ltd.
Congestion‐free routing strategy in software defined data center networks
Authors: Li Yan , Li Wenxin , Chen Honghui , Guo Deke , Zhang Tian , Qu Ting 
Published: October 2015

SummaryLarge‐scale online services and distributed execution engines (i.e., MapReduce and Dryad) generate large volumes of traffic in data center networks. As a consequence, significant congestion can occur in the data center network. To the best of our knowledge, most existing approaches either focus on local congestion‐aware mechanisms, which have only a poor ability to handle asymmetry or use explicit congestion notification packets, which are difficult to implement directly in switch hardware. These methods are insufficient to solve the congestion problem. In this paper, we focus on a congestion‐free routing strategy, resorting to the global view of the data center network in a software‐defined networking controller. Specifically, a timeslot allocation was first conducted for the coming packets, and then the corresponding routing paths were computed for each packet. In view of the efficiency, the timeslot allocation algorithm follows a heuristic pattern, and the path selection is modeled as a bin‐packing problem. Simulation results showed that the congestion‐free routing strategy proposed here performs well in throughput, queuing, and end‐to‐end round‐trip time. Copyright © 2015 John Wiley & Sons, Ltd.
FRP: a fast resource placement algorithm in distributed cloud computing platform
Authors: Wei Wei , Zhang Yuhong , Liu Yang , Qin Zhiguang 
Published: October 2015

SummaryWe consider a large‐scale online service system of placing resources geographically distributed over multiple regional cloud data centers. Service providers need to place the resources in these regions so as to maximize profit, accounting for demand granting revenues minus resource placement costs. The challenge is how to optimally place these resources to fulfill varying demands (e.g., multidimensional and stochastic demands) among these cloud data centers. Considering demand stochasticity will significantly increase time complexity of resource placement algorithm, resulting in inefficiency when handling a large number of resources. We propose a fast resource placement algorithm (FRP) to obtain the maximum resource revenue from distributed cloud systems. Experiments show that in scenarios with general settings, FRP can achieve up to 99.2% revenue of existed best solution while reducing execution time by two orders of magnitude. Therefore, FRP is an effective supplement to existing algorithms under time‐tense scheduling scenarios with a large number of resources. Copyright © 2015 John Wiley & Sons, Ltd.
