<div class="page" title="Page 1"><div class="layoutArea"><div class="column"><p><span>Since the publication of Phil Agre’s [1] seminal work on critical technical practice, the sites of intersection between computation and society have multiplied, and so too have the sociotechnical borderlands we inhabit. Critical methodologies such as “critical design” [8,6,5], “reflective design” [3,4,7,9,15,12], “critical making” [11,6,7], “located accountability” [13, 14], “feminist HCI” [2], and “postcolonial computing” [10] have proliferated and are being taken up in increasingly diverse political, cultural and social contexts. As the sites of critical praxis have multiplied, new regimes like big data and social computing pose new challenges. Given the fluidity of the landscape it is important for us to articulate the specificities of our scholarly borderlands. By bringing together junior and senior scholars we aim to provide a forum for researchers in this area to learn from each other how to navigate changing terrains of technology research and design. To maximize in- depth collaboration between junior and senior scholars, we propose a format that includes in-depth mentoring sessions, panel presentations from junior and senior participants, group activities, and working sessions for steps forward. The goal of the proposed workshop is to foster cohesion and build mentoring relationships within the community by creating a space for open and honest dialogue about the challenges of conducting critical research and design practice. Outcomes from this workshop will be a shared knowledge base about praxis, tracing the trajectories, continuities, traversals and inheritances of critical sociotechnical research over the past decade, as well as strengthening of the critical technical practice community by way of establishing lasting mentorship relations. </span></p></div></div></div>

Abstract
Marine protected area or marine reserve was first conducted in Central Visayas in 1974 as a tool to manage coral reef. It was then replicated throughout the Philippines. The marine reserve of the following; Casay of Argao, Cawayan of Dalaguete, Daan-Lungsod Guiwang of Alcoy, North Granada of Boljoon and Sta. Cruz of Ronda has been established between the years 2000 to 2007. These MPAs were assessed to gather baseline information on its coral lifeform structure. Point-intercept transect (PIT) method was used in the observation. Benthic life form and reef substrate at each 0.25m point interval were identified and recorded along 50 meters transect line both inside and outside of these MPAs. It has been observed that massive, branching and digitate form of corals dominated among the five sanctuaries. Percentage of Live Hard Corals were much higher inside than outside to all sanctuaries. Common to all these sanctuaries were noticeable presence of Dead corals with algae and coral rubbles indicating its exploitation. Casay, Cawayan and Daan-Lungsod MPAs had some Crown of thorn starfish which may pose threat to its coral community. It has been recommended that there should be strict implementation of rules among the Local Government Unit; more policing and a long term monitoring to continuously conserve and protect coral reef.
A 1‐D morphodynamic model of postglacial valley incision
Authors: Tunnicliffe Jon F. , Church Michael 
Published: October 2015

AbstractChilliwack River is typical of many Cordilleran valley river systems that have undergone dramatic Holocene degradation of valley fills that built up over the course of Pleistocene glaciation. Downstream controls on base level, mainly blockage of valleys by glaciers, led to aggradation of significant glaciofluvial and glaciolacustrine valley fills and fan deposits, subsequently incised by fluvial action. Models of such large‐scale, long‐term degradation present a number of important challenges since the evolution of model parameters, such as the rate of bedload transport and grain size characteristics, are governed by the nature of the deposit. Sediment sampling in the Chilliwack Valley reveals a complex sequence of very coarse to fine textural modes. We present a 1‐D numerical morphodynamic model for the river‐floodplain system tailored to conditions in the valley. The model is adapted to dynamically adjust channel width to optimize sediment transporting capacity and to integrate relict valley fill material as the channel incises through valley deposits. Sensitivity to model parameters is studied using four principal criteria: profile concavity, rate of downstream grain size fining, bed surface sand content, and the timescale to equilibrium. Model results indicate that rates of abrasion and coarsening of the grain size distributions exert the strongest controls on all of the interrelated model performance criteria. While there are a number of difficulties in satisfying all model criteria simultaneously, results indicate that 1‐D models of valley bottom sedimentary systems can provide a suitable framework for integrating results from sediment budget studies and chronologies of sediment evacuation established from dating.
A previously unreported type of seismic source in the firn layer of the East Antarctic Ice Sheet

AbstractWe identify a unique type of seismic source in the uppermost part of the East Antarctic Ice Sheet recorded by temporary broadband seismic arrays in East Antarctica. These sources, termed “firnquakes,” are characterized by dispersed surface wave trains with frequencies of 1–10 Hz detectable at distances up to 1000 km. Events show strong dispersed Rayleigh wave trains and an absence of observable body wave arrivals; most events also show weaker Love waves. Initial events were discovered by standard detection schemes; additional events were then detected with a correlation scanner using the initial arrivals as templates. We locate sources by determining the L2 misfit for a grid of potential source locations using Rayleigh wave arrival times and polarization directions. We then perform a multiple‐filter analysis to calculate the Rayleigh wave group velocity dispersion and invert the group velocity for shear velocity structure. The resulting velocity structure is used as an input model to calculate synthetic seismograms. Inverting the dispersion curves yields ice velocity structures consistent with a low‐velocity firn layer ~100 m thick and show that velocity structure is laterally variable. The absence of observable body wave phases and the relative amplitudes of Rayleigh waves and noise constrain the source depth to be less than 20 m. The presence of Love waves for most events suggests the source is not isotropic. We propose the events are linked to the formation of small crevasses in the firn, and several events correlate with shallow crevasse fields mapped in satellite imagery.

ObjectiveThe diagnosis of mitochondrial disorders (MDs) is occasionally difficult because patients often present with solitary, or a combination of, symptoms caused by each organ insufficiency, which may be the result of respiratory chain enzyme deficiency. Growth differentiation factor 15 (GDF‐15) has been reported to be elevated in serum of patients with MDs. In this study, we investigated whether GDF‐15 is a more useful biomarker for MDs than several conventional biomarkers.MethodsWe measured the serum levels of GDF‐15 and fibroblast growth factor 21 (FGF‐21), as well as other biomarkers, in 48 MD patients and in 146 healthy controls in Japan. GDF‐15 and FGF‐21 concentrations were measured by enzyme‐linked immunosorbant assay and compared with lactate, pyruvate, creatine kinase, and the lactate‐to‐pyruvate ratio. We calculated sensitivity and specificity and also evaluated the correlation based on two rating scales, including the Newcastle Mitochondrial Disease Rating Scale (NMDAS).ResultsMean GDF‐15 concentration was 6‐fold higher in MD patients compared to healthy controls (2,711 ± 2,459 pg/ml vs 462.5 ± 141.0 pg/mL; p < 0.001). Using a receiver operating characteristic curve, the area under the curve was significantly higher for GDF‐15 than FGF‐21 and other conventional biomarkers. Our date suggest that GDF‐15 is the most useful biomarker for MDs of the biomarkers examined, and it is associated with MD severity.InterpretationOur results suggest that measurement of GDF‐15 is the most useful first‐line test to indicate the patients who have the mitochondrial respiratory chain deficiency.

Published: October 2015

AbstractDie Prozessierung organischer Bauelemente aus der Flüssigphase ist ein wichtiger Schritt zur Entwicklung kostengünstiger Fertigungsprozesse. Wir beschreiben eine Methode zur lichtinduzierten Löslichkeitsschaltung eines π‐konjugierten Polymers (Polyfluoren), dessen Seitenketten mit Hydroxyzimtsäureester funktionalisiert sind. Die Belichtung dünner Polymerfilme führt zur Abspaltung der Seitenketten, wodurch die Löslichkeit der Filme drastisch gesenkt wird. In einer ersten Konzeptstudie wurden die synthetisierten Polyfluorene als Emittermaterialien in OLEDs eingesetzt. Belichtung der Emitterschicht führt außer der Löslichkeitsschaltung auch zu einem deutlichen Leistungsanstieg der OLED. Dieser Befund eröffnet die Möglichkeit zur gezielten Manipulation der Löslichkeit und der Emissionseigenschaften einer wichtigen Klasse funktioneller Materialien.
Relative Lability and Chemoselective Transmetallation of NHC in Hybrid Phosphine‐NHC Ligands: Access to Heterometallic Complexes
Authors: Simler Thomas , Braunstein Pierre , Danopoulos Andreas A. 
Published: October 2015

AbstractThe relative lability and transmetallation aptitude of trialkylphosphine and NHC donors, integrated in semi‐rigid hybrid ligands attached to [Ag4Br4] pseudo‐cubanes, lies in favor of the NHC and is used to selectively access unprecedented NHC complexes with heterobimetallic cores, such as Ag–Cu (4Cy) and Ag–Ir (5tBu). These can be viewed as an arrested state before the full transmetallation of both donors, which gives the homodinuclear Cu (3Cy) and Ir (6Cy) complexes. The observed NHC transmetallation aptitude and reactivity urges caution in the common notion that views the NHC as a universal spectator.
Boosting Photocatalytic Water Splitting: Interfacial Charge Polarization in Atomically Controlled Core–Shell Cocatalysts

Published: October 2015

AbstractPlatinum is a commonly used cocatalyst for improved charge separation and surface reactions in photocatalytic water splitting. It is envisioned that its practical applications can be facilitated by further reducing the material cost and improving the efficacy of Pt cocatalysts. In this direction, the use of atomically controlled Pd@Pt quasi‐core–shell cocatalysts in combination with TiO2 as a model semiconductor is described. As demonstrated experimentally, the electron trapping necessary for charge separation is substantially promoted by combining a Schottky junction with interfacial charge polarization, enabled by the three‐atom‐thick Pt shell. Meanwhile, the increase in electron density and lattice strain would significantly enhance the adsorption of H2O onto Pt surface. Taken together, the improved charge separation and molecular activation dramatically boost the overall efficiency of photocatalytic water splitting.

Published: October 2015

AbstractLiquid‐phase processing is a key prerequisite for the cost‐efficient fabrication of organic electronic devices. We report an approach for light‐induced modulation of the solubility of π‐conjugated polymers (polyfluorene) with side chains functionalized with hydroxycinnamic acid. Irradiation with light cleaves the solubilizing side chains and renders the thin films of the polyfluorene insoluble. In a proof of concept device, polyfluorenes were applied as emissive layers in OLEDs. Photoirradiation of the emission layer leads to an increase in OLED performance combined with a modulation of the solubility of the thin film. These results offer the possibility for further development in terms of manipulating the solubility and emissive parameters of an important class of functional materials.
A Ca2+‐, Mg2+‐, and Zn2+‐Based Dendritic Contractile Nanodevice with Two pH‐Dependent Motional Functions
Authors: Stadler Adrian‐Mihail , Karmazin Lydia , Bailly Corinne 
Published: October 2015

AbstractA contractile dendritic motional device is reported where metal ions with biological importance—Ca2+ (the main regulatory and signaling species of the natural muscles), Mg2+, and Zn2+—initiate two kinds of motional functions. The first motional function is the metal‐ion‐induced contraction of a linear strand into a Z‐shaped dinuclear complex, and the second one is the change of the height of Z‐shaped complexes via transmetalation. By means of the pH‐dependent counterligand tren, the two motional features of the machine can depend on alternate additions of acid and base. An optical response is associated with the conversion of the linear form (which is yellow) into the metalated Z‐shaped one (which is red).
The ANKK1/DRD2 locus is a genomic substrate for affective priming and recognition of angry faces

Published: October 2015

AbstractIntroductionAnkyrin repeat and kinase domain containing I (ANKK1) and dopamine D2 receptor (DRD2) genes have been associated with psychopathic traits in clinical samples. On the other hand, individuals high in psychopathy show reduced affective priming and deficits in facial expression recognition. We have hypothesized that these emotion‐related cognitive phenomena are associated with TaqIA (rs18000497) SNP (single nucleotide polymorphism) of the ANKK1 gene and with C957T (rs6277) SNP of the DRD2 gene.MethodsWe performed a genetic association analysis in 94 self‐reported Caucasian healthy volunteers. The participants completed 144 trials of an affective priming task, in which primes and targets were emotional words. They also had to recognize 64 facial expressions of happiness, sadness, anger, and fear in an expression recognition task. Regarding the genetic analyses, TaqIA and C957T SNPs were genotyped.ResultsWe found that the C957T SNP TT genotype was associated with a stronger priming effect and a better recognition of angry expressions. No associations were found for the TaqIA SNP. In addition, in silico analysis demonstrated that C957T SNP is a marker of a regulatory sequence at the 5′ UTR of ANKK1 gene, thus suggesting the involvement of the whole ANKK1/DRD2 locus in cognitive–emotional processing.ConclusionsThese results suggest that affective priming and recognition of angry facial expressions are endophenotypes that lie on the pathway between the ANKK1/DRD2 locus and some deviant phenotypes.
Design of experiment course “Computer‐aided landscape design” based on flipped classroom

Published: October 2015

ABSTRACTThe purpose of this study was to assess the effectiveness of a traditional lecture‐based curriculum versus a modified “flipped classroom” curriculum of “computer‐aided landscape design” delivered to the second‐year undergraduate students. Students in both courses were provided the same notes and recorded lectures. Students in the modified flipped classroom were distributed the teaching case so that they can produce the effect diagram according to their own ideas before class and then attend class, discussing and trying to solve problems they met. In the traditional curriculum, the students were only asked to prepare a new lesson while the case was not distributed. Within a comparable group of graduate students, participants in the flipped class scored significantly higher (P < 0.05) on the “computer‐aided landscape design” by an average of >3 percentage points. The scores of learning attitude and learning motivation of the test group is significantly higher than that of controlled group (P < 0.05). According to our experience and surveys on students, we propose that the teaching cases made by the students before class are critical motivating factors which are likely to help student study. Independently taken together, our findings suggest that the flipped classroom model is a highly effective means which improves the undergraduates' skills of making effect charts. © 2015 Wiley Periodicals, Inc.

Single‐Crystal to Single‐Crystal Linker Substitution, Linker Place Exchange, and Transmetalation Reactions in Interpenetrated Pillared–Bilayer Zinc(II) Metal–Organic Frameworks

Published: October 2015

AbstractA twofold interpenetrated pillared–bilayer framework, {[Zn3(L)2(L2)(DMF)]⋅(18DMF)(6H2O)}n (1), has been synthesized from the ligands tris(4′‐carboxybiphenyl)amine (H3L) and 1,2‐bis(4‐pyridyl)ethylene (L2). The structure contains [Zn3(COO)6] secondary building units (SBUs), in which three ZnII ions are almost linear with carboxylate bridging. This framework undergoes reversible pillar linker substitution reactions at the terminal ZnII centers with three different dipyridyl linkers of different lengths to afford three daughter frameworks, 2–4. Frameworks 2–4 are interconvertible through reversible linker substitution reactions. Also, competitive linker‐exchange experiments show preferential incorporation of linker L3 in the parent framework 1. The larger linker L5 does not undergo such substitution reactions and framework 5, which contains this linker, can be synthesized solvothermally as a twofold interpenetrated structure. Interestingly, when framework 5 is dipped in a solution of L3 in DMF, linker substitution takes place as before, but linker L5 now moves and diagonally binds two ZnII centers to afford 6 as a nonpenetrated single framework. This linker place exchange reaction is unprecedented. All of these reactions take place in a single‐crystal to single‐crystal (SC‐SC) manner, and have been observed directly through X‐ray crystallography. In addition, each 3D framework undergoes complete copper(II) transmetalation.
Metalated Hexaphyrins: From Understanding to Rational Design
Authors: Alonso Mercedes , Pinter Balazs , Geerlings Paul , De Proft Frank 
Published: October 2015

AbstractThe heretofore unpredictable behavior of [26] and [28]hexaphyrins upon metalation has been elucidated through quantum chemical calculations. It is demonstrated that the molecular topology of Group 10 and Group 11 metal complexes of hexaphyrins depends on sensitive interplay between the intrinsic ligand strain and the metal–ligand interaction strength. As such, the aromaticity of the ligand and effective charge of the metal are revealed as key factors determining the binding mode and the preference for Möbius or Hückel structures. These findings offer a new perspective to rationalize experimental observations for metalated hexaphyrins. More importantly, the proposed guidelines could be useful for designing novel complexes of hexaphyrins, such as a hitherto unknown Möbius [26]hexaphyrin complex.
