Looking for Mr Hyde: The protest paradigm, violence and (de)legitimation of mass political protests
Authors: Trivundža Ilija Tomanić , Brlek Sašo Slaček 
Published: May 2017

Abstract
This article analyses the shifting use of violence as a framing device that determines the legitimacy of political actors in mainstream media coverage of mass political protests. Building on an analysis of news reports on the largest political protests in Slovenia in the past two decades, which lasted between November 2012 and March 2013, we show how violence can be used as a ‘floating’ framing device that articulates the legitimacy or illegitimacy of protesters at large, and of specific groups of protesters, state institutions (e.g. police) and political elites. The analysis is grounded in the tradition of ‘protest paradigm’ research but is conducted according to a revised analytical framework, which better captures the nuances of mainstream media reports on mass protests and the complexities of contemporary protest action. A qualitative multimodal analysis of protest coverage in the main evening news programmes of two leading Slovene mainstream news sources – commercial TV station POP TV and national public broadcaster TV Slovenia – shows that mainstream media can resort to providing a normative social function, even in cases when protesters are framed as legitimate political subjects. It also shows that the legitimization of protesters as political subjects does not necessarily imply legitimization of their explicitly political challenges to the status quo, but can serve to shift the discourse from the sphere of politics to that of morality.
Corporate influence on the media in South Korea: The case of Samsung
Authors: Kwak Ki-Sung 
Published: May 2017

Abstract
This article is designed to broaden the understanding of South Korean newspapers’ journalistic practices. It examines the editorial approaches of two contrasting sets of newspapers towards corruption accusations and judicial proceedings against a leading corporation, Samsung. Through an analysis of the degree to which the ideological leanings and economic interests of the newspapers are reflected in their editorials on this issue, it shows that the journalistic practices of South Korean newspapers have been mixed. In addressing to what extent the financial viability of newspapers influences their news reporting, this article shows that there is a complex interplay of ideological inclination and economic interests in their reporting on economic corruption. It argues that the watchdog role performed by the newspapers, conservative newspapers in particular, in relation to the powerful economic and corporate actors represented by business conglomerates, has to a large extent been subordinated to the papers’ organizational and economic interests.
Evolving media structures in Central America
Authors: Rockwell Rick 
Published: May 2017

Abstract
Advances in social media and Internet penetration mask the long-time collusion between media owners, political elites and other forces running the countries of Central America. This analysis focuses primarily on the Northern Triangle countries of Guatemala, Honduras and El Salvador to examine the media systems that have supported conservative control in this region. Yet media evolution in the region is underway and the structures of the last century could eventually shift. This study earmarks some of those new factors while illuminating the existing structures.
Muscle or muzzle? A critical analysis of media, power and censorship in democratic India
Authors: Kumar Lata Rajagopalan 
Published: May 2017

Abstract
The controversy around media, power and censorship in democratic India is centred around the debate over the pros and cons of total freedom of expression. The freedom of speech guaranteed by the Constitution of India can be suppressed if it is considered objectionable, harmful, or a threat to communal harmony. Governments across the globe have used religious, political and other powerful arguments to support their censorship efforts. Offensive communication in the eyes of the government varies from country to country, religion to religion, even sect to sect. Many governments provide for certain limited protection against censorship. It is always necessary to balance conflicting rights in order to determine what can and cannot be censored. The past few years in India have seen films, rock bands, websites, Internet articles, events, documentaries and books restricted or totally banned under various censorship laws. These occurrences have sparked widespread criticism. This article takes a closer look at recent instances of media censorship, the reasons behind the decisions and the reactions of the Indian people. The discussion is within the framework of existing laws in India, historical background and culture, and examines the future of Indian media in the context of power and censorship.
Cultivating curatorial habits of mind through studentcreated exhibitions
Authors: Marsh Joanna , Showalter Anne 
Published: May 2017

Abstract
This article presents a descriptive and analytical account of a semester-long partnership between museum educators and high school students piloting the National Coalition for Core Arts Standards Visual Arts Model Cornerstone Assessment. To mentor the students through their task of curating a themed art exhibition of their own work at school, museum educators modelled curatorial strategies, best practices, and lines of questioning that the students later adapted and applied to their own exhibition planning process. The resulting collaboration reveals the deeply authentic, if under-recognized, relationship between curatorial practice and art education practice and offers a compelling case for breaking down traditional barriers between curators and museum educators in order to create a generative space in which to cultivate student curators across multiple disciplines.
Logical curating: Unraveled: Textiles Reconsidered, 2016
Authors: Bonansinga Kate 
Published: May 2017

Abstract
This article describes the planning and development of the 2016 exhibition Unraveled: Textiles Reconsidered as a case study to investigate contemporary art curating as research; curatorial methodology as an approach to problem solving; and curatorial process as a driver of curatorial decision making. The author of this essay guest curated Unraveled: Textiles Reconsidered for the Contemporary Arts Center in Cincinnati, Ohio, where it was on view from 22 April 2016 to 14 August 2016. As a component of the argument the article iterates the CAC’s institutional mission and educational art making workshops. The logic of how, when and why curatorial decisions were made can be applied to many other types of creative decision-making.
The curatorial turn of curricular architecture
Authors: Garoian Charles R. 
Published: May 2017

Abstract
In this writing, I conceptualize the curricular explorations, experiments and improvisations in a collaborative high school art and architecture history course as a curatorial riffing that activated a curricular architecture from which new and differential histories emerged. Homologous with curatorial experimentation, the curriculum consisted of historical and contemporary works of art and architecture positioned alongside disparate, seemly unrelated tasks, events, and students’ memories and cultural histories to evoke from their interstices a plurality of discursive encounters, alliances and emissions. The curatorial contingencies of that curriculum will be conceptualized in contiguity with the following theoretical constructs: the movement-image and time-image of Gilles Deleuze as they activate thinking standardized figurations of curricular scope and sequence differently; thinking historical discourse as a curatorial plurality according to Michel Foucault’s notions of heterotopia and genealogy differently from hegemonic curricular constructs; and, the implications of Paul O’Neill’s concept of the curator as artist in thinking curricular creation in terms of curatorial performance.
When the display matters: A multifaceted perspective on 3D geovisualizations

Published: May 2017

AbstractThis study explores the influence of stereoscopic (real) 3D and monoscopic (pseudo) 3D visualization on the human ability to reckon altitude information in noninteractive and interactive 3D geovisualizations. A two phased experiment was carried out to compare the performance of two groups of participants, one of them using the real 3D and the other one pseudo 3D visualization of geographical data. A homogeneous group of 61 psychology students, inexperienced in processing of geographical data, were tested with respect to their efficiency at identifying altitudes of the displayed landscape. The first phase of the experiment was designed as non-interactive, where static 3D visual displayswere presented; the second phase was designed as interactive and the participants were allowed to explore the scene by adjusting the position of the virtual camera. The investigated variables included accuracy at altitude identification, time demands and the amount of the participant’s motor activity performed during interaction with geovisualization. The interface was created using a Motion Capture system, Wii Remote Controller, widescreen projection and the passive Dolby 3D technology (for real 3D vision). The real 3D visual display was shown to significantly increase the accuracy of the landscape altitude identification in non-interactive tasks. As expected, in the interactive phase there were differences in accuracy flattened out between groups due to the possibility of interaction, with no other statistically significant differences in completion times or motor activity. The increased number of omitted objects in real 3D condition was further subjected to an exploratory analysis.

Abstract

Background

Zingiber officinale Roscoe has been used in traditional medicine for the treatment of neurological disorder. This study aimed to investigate the phenolic contents, antioxidant, acetylcholinesterase enzyme (AChE) inhibitory activities of different fraction of Z. officinale root grown in Vietnam.

Methods
The roots of Z. officinale are extracted with ethanol 96 % and fractionated with n-hexane, ethyl acetate (EtOAc) and butanol (BuOH) solvents. These fractions evaluated the antioxidant activity by 1,1-Diphenyl -2-picrylhydrazyl (DPPH) assay and AChE inhibitory activity by Ellman’s colorimetric method.

Results
Our data showed that the total phenolic content of EtOAc fraction was highest equivalents to 35.2±1.4 mg quercetin/g of fraction. Our data also demonstrated that EtOAc fraction had the strongest antioxidant activity with IC50 was 8.89±1.37 µg/mL and AChE inhibitory activity with an IC50 value of 22.85±2.37 μg/mL in a dose-dependent manner, followed by BuOH fraction and the n-hexane fraction is the weakest. Detailed kinetic analysis indicated that EtOAc fraction was mixed inhibition type with Ki (representing the affinity of the enzyme and inhibitor) was 30.61±1.43 µg/mL.

Conclusions
Our results suggest that the EtOAc fraction of Z. officinale may be a promising source of AChE inhibitors for Alzheimer’s disease.
MAX-SAT Problem using Hybrid Harmony Search Algorithm

Published: May 2017

Abstract
Maximum Satisfiability problem is an optimization variant of the Satisfiability problem (SAT) denoted as MAX-SAT. The aim of this problem is to find Boolean variable assignment that maximizes the number of satisfied clauses in the Boolean formula. In case the number of variables per clause is equal or greater than three, then this problem is considered NP-complete. Hence, many researchers have developed techniques to deal with MAX-SAT. In this paper, we investigate the impact of different hybrid versions of binary harmony search (HS) algorithm on solving MAX 3-SAT problem. Therefore, we propose two novel hybrid binary HS algorithms. The first hybridizes Flip heuristic with HS, and the second uses Tabu search combined with Flip heuristic. Furthermore, a distinguished feature of our proposed approaches is using an objective function that is updated dynamically based on the stepwise adaptation of weights (SAW) mechanism to evaluate the MAX-SAT solution using the proposed hybrid versions. The performance of the proposed approaches is evaluated over standard MAX-SAT benchmarks, and the results are compared with six evolutionary algorithms and three stochastic local search algorithms. The obtained results are competitive and show that the proposed novel approaches are effective.

Published: May 2017

Abstract
Genomic instability, including genetic mutations and chromosomal rearrangements, can lead to cancer development. Aberrant DNA methylation occurs commonly in cancer cells. The aim of this study is to determine the effects of a specific chromosomal lesion the BCR-ABL translocation t(9:22), in establishing DNA methylation profiles in cancer. Materials and methods We compared DNA methylation of 1,505 selected promoter CpGs in chronic myelogenous leukemia (CML), acute lymphoblastic leukemia (ALL) with and without the Philadelphia chromosome t(9:22), CD34+ hematopoietic stem cells transfected with BCR-ABL, and other tumors without BCR-ABL (acute promyelocytic leukemia (APL) and gastrointestinal stromal tumors (GIST). In this study, the DNA methylation profile of CML was more closely related to APL, another myeloid leukemia, than Ph+ ALL. Although DNA methylation profiles were consistent within a specific tumor type, overall DNA methylation profiles were no influenced by BCR-ABL gene translocation in the cancers and tissues studied. We conclude that DNA methylation profiles may reflect the cell of origin in cancers rather than the chromosomal lesions involved in leukemogenesis.

Offene Werkstätten und Postwachstumsökonomien: kollaborative Orte als Wegbereiter transformativer Wirtschaftsentwicklungen?
Authors: Lange Bastian 
Published: May 2017

Zusammenfassung:
In jüngster Zeit richtet sich ein Fokus der Postwachstumsdebatte auf sogenannte offene Werkstätten (z. B. Siebdruck-, Fahrradwerkstätten, Repair Cafés, FabLabs u. a.) und die sich dabei vollziehenden offenen kollaborativen Prozesse. Im diskursiven Umfeld finden sich neben dem Phänomen offene Werkstatt weitere Orte wie Living Labs, Reallabore und FabLabs. Entgegen dem vorherrschenden Wachstumsparadigma von zahlreichen regionalökonomischen Ansätzen eröffnet sich eine lebendige, transdisziplinäre Debatte zur Erfassung neuer und alternativer Konzepte von Produktionsprozessen. Die folgenden empirischen Ergebnisse am Fall offener Werkstätten zeigen, dass zukünftig von kontingenten und fallspezifischen Wirtschaftsentwicklungen auszugehen ist, bei denen die Fähigkeit zur Problemansprache und deren prozessuale Lösung in Themengemeinschaften wichtiger als die faktischen stofflichen Material- und Ressourceneinsparungen von offenen Werkstätten sind.
Electron-counting in intermetallics made easy: the 18-n rule and isolobal bonds across the Os–Al system
Authors: Miyazaki Ken , Yannello Vincent J. , Fredrickson Daniel C. 
Published: May 2017

Abstract
Electron count is one of the key factors controlling the formation of complex intermetallic structures. The delocalized nature of bonding in metals, however, has made it difficult to connect these electron counts to the various structural features that make up complex intermetallics. In this article, we illustrate how structural progressions in transition metal-main group intermetallics can in fact be simply understood with the 18-n bonding scheme, using as an example series the four binary phases of the Os–Al system. Our analysis begins with the CsCl-type OsAl phase, whose 11 electrons/Os count is one electron short of that predicted by the 18-n rule. This electron deficiency provides a driving force for Al incorporation to make more Al-rich intermetallic phases. In the structures of Os2Al3 (own type) and OsAl2 (MoSi2 type), each additional Al atom contributes three electrons, two of which go towards cleaving Os–Os isolobal bonds, with the third alleviating the original electron deficiency of OsAl. Across the series, the framework of isolobal Os–Os bonds is reduced from a primitive cubic network (n=6, OsAl) to layers of cubes (n=5, Os2Al3) to individual square nets (n=4, OsAl2). Upon adding more Al to form Os4Al13, the Os–Os contacts are further reduced to dumbbells at the interfaces between fluorite-type columns. At this point, the added Al raises the electron count beyond that needed for filled octadecets on the Os atoms; the excess electrons are accommodated by Al–Al bonds. Throughout this work, we emphasize how the 18-n scheme can be applied from structural inspection alone, with theoretical calculations confirming or refining these conclusions.

Published: May 2017

Abstract
In many applications it has been found that the standard generalized gradient approximation (GGA) does not accurately describe weak chemical bond and electronic properties of solids containing transition metals. In this work, we have considered the intercalation material 1T-Li
x
TiS2 (0≤x≤1) as a model system for the evaluation of the accuracy of GGA and corrected GGA with reference to the availabile experimental data. The influence of two different dispersion corrections (D3 and D-TS) and an on-site Coulomb repulsion term (GGA+U) on the calculated structural and electronic properties is tested. All calculations are based on the Perdew-Burke-Ernzerhof (PBE) functional. An effective U value of 3.5 eV is used for titanium. The deviation of the calculated lattice parameter c for TiS2 from experiment is reduced from 14 % with standard PBE to −2 % with PBE+U and Grimme’s D3 dispersion correction. 1T-TiS2 has a metallic ground state at PBE level whereas PBE+U predicts an indirect gap of 0.19 eV in agreement with experiment. The 7Li chemical shift and quadrupole coupling constants are in reasonable agreement with the experimental data only for PBE+U-D3. An activation energy of 0.4 eV is calculated with PBE+U-D3 for lithium migration via a tetrahedral interstitial site. This result is closer to experimental values than the migration barriers previously obtained at LDA level. The proposed method PBE+U-D3 gives a reasonable description of structural and electronic properties of 1T-Li

Los programas, tan llenos a veces de objetivos y contenidos de carácter repetitivo, apartan muy a menudo a la infancia y a la juventud del gozo de la experimentación, del placer de la creación, de la comunicación con los demás, del conocimiento de los valores de los compañeros que les rodean. Es necesario reconocer que nuestra sociedad actual necesita humanizarse, recibir emociones personales positivas. En cambio, cada vez tenemos más chicos y chicas introvertidos, con problemas de relación y comunicación. Los profesores y profesoras debemos aunar, rectificar, y modificar para que nuestros alumnos sepan incluir en su vida un poquito de creatividad y conocimiento personal. El juego teatral puede ser un maravilloso recurso para trabajar las relaciones personales y sociales y ayudar especialmente a los alumnos/as que necesitan desarrollar ese tipo de habilidades. Aquí mostramos un estudio de caso donde un alumno con dificultades en habilidades sociales, y que le había llevado a una terrible relación con sus iguales, recibe terapia a través de un grupo de teatro escolar de forma normalizada e inclusiva. Consiguiendo grandes logros en su desarrollo personal, afectivo y social. José Cañas nos invita a llevar a cabo la misión de animar al profesorado para que den el paso de pintar de color y calor cada uno de los centros, cada una de las aulas, cada una de las almas de nuestros chicos y chicas.
USP4 inhibits SMAD4 monoubiquitination and promotes activin and BMP signaling

Published: May 2017

AbstractSMAD4 is a common intracellular effector for TGF‐β family cytokines, but the mechanism by which its activity is dynamically regulated is unclear. We demonstrated that ubiquitin‐specific protease (USP) 4 strongly induces activin/BMP signaling by removing the inhibitory monoubiquitination from SMAD4. This modification was triggered by the recruitment of the E3 ligase, SMURF2, to SMAD4 following ligand‐induced regulatory (R)‐SMAD–SMAD4 complex formation. Whereas the interaction of the negative regulator c‐SKI inhibits SMAD4 monoubiquitination, the ligand stimulates the recruitment of SMURF2 to the c‐SKI‐SMAD2 complex and triggers c‐SKI ubiquitination and degradation. Thus, SMURF2 has a role in termination and initiation of TGF‐β family signaling. An increase in monoubiquitinated SMAD4 in USP4‐depleted mouse embryonic stem cells (mESCs) decreased both the BMP‐ and activin‐induced changes in the embryonic stem cell fate. USP4 sustained SMAD4 activity during activin‐ and BMP‐mediated morphogenic events in early zebrafish embryos. Moreover, zebrafish depleted of USP4 exhibited defective cell migration and slower coordinated cell movement known as epiboly, both of which could be rescued by SMAD4. Therefore, USP4 is a critical determinant of SMAD4 activity.
Bacilli glutamate dehydrogenases diverged via coevolution of transcription and enzyme regulation
Authors: Noda‐Garcia Lianet , Romero Romero Maria Luisa , Longo Liam M , Kolodkin‐Gal Ilana , Tawfik Dan S 
Published: May 2017

AbstractThe linkage between regulatory elements of transcription, such as promoters, and their protein products is central to gene function. Promoter–protein coevolution is therefore expected, but rarely observed, and the manner by which these two regulatory levels are linked remains largely unknown. We study glutamate dehydrogenase—a hub of carbon and nitrogen metabolism. In Bacillus subtilis, two paralogues exist: GudB is constitutively transcribed whereas RocG is tightly regulated. In their active, oligomeric states, both enzymes show similar enzymatic rates. However, swaps of enzymes and promoters cause severe fitness losses, thus indicating promoter–enzyme coevolution. Characterization of the proteins shows that, compared to RocG, GudB's enzymatic activity is highly dependent on glutamate and pH. Promoter–enzyme swaps therefore result in excessive glutamate degradation when expressing a constitutive enzyme under a constitutive promoter, or insufficient activity when both the enzyme and its promoter are tightly regulated. Coevolution of transcriptional and enzymatic regulation therefore underlies paralogue‐specific spatio‐temporal control, especially under diverse growth conditions.
