Abstract
The Hubble Space Telescope photometric survey of Galactic globular clusters (GCs) has revealed a peculiar “chromosome map” for NGC 6934. In addition to a typical sequence, similar to that observed in Type I GCs, NGC 6934 displays additional stars on the red side, analogous to the anomalous Type II GCs, as defined in our previous work. We present a chemical abundance analysis of four red giants in this GC. Two stars are located on the chromosome map sequence common to all GCs, and another two lie on the additional sequence. We find (i) star-to-star Fe variations, with the two anomalous stars being enriched by ∼0.2 dex. Because of our small-size sample, this difference is at the ∼2.5σ level. (ii) There is no evidence for variations in the slow neutron-capture abundances over Fe, at odds with what is often observed in anomalous Type II GCs, e.g., M 22 and ω Centauri; (iii) no large variations in light elements C, O, and Na, compatible with locations of the targets on the lower part of the chromosome map where such variations are not expected. Since the analyzed stars are homogeneous in light elements, the only way to reproduce the photometric splits on the sub-giant (SGB) and the red giant (RGB) branches is to assume that red RGB/faint SGB stars are enhanced in [Fe/H] by ∼0.2. This fact corroborates the spectroscopic evidence of a metallicity variation in NGC 6934. The observed chemical pattern resembles only partially the other Type II GCs, suggesting that NGC 6934 might belong either to a third class of GCs, or be a link between normal Type I and anomalous Type II GCs.

Abstract
The late-time light curves of Type Ia supernovae (SNe Ia), observed >900 days after explosion, present the possibility of a new diagnostic for SN Ia progenitor and explosion models. First, however, we must discover what physical process (or processes) leads to the slow-down of the light curve relative to a pure 56Co decay, as observed in SNe 2011fe, 2012cg, and 2014J. We present Hubble Space Telescope observations of SN 2015F, taken ≈600–1040 days past maximum light. Unlike those of the three other SNe Ia, the light curve of SN 2015F remains consistent with being powered solely by the radioactive decay of 56Co. We fit the light curves of these four SNe Ia in a consistent manner and measure possible correlations between the light-curve stretch—a proxy for the intrinsic luminosity of the SN—and the parameters of the physical model used in the fit. We propose a new, late-time Phillips-like correlation between the stretch of the SNe and the shape of their late-time light curves, which we parameterize as the difference between their pseudo-bolometric luminosities at 600 and 900 days: ΔL
900 = log(L
600/L
900). Our analysis is based on only four SNe, so a larger sample is required to test the validity of this correlation. If true, this model-independent correlation provides a new way to test which physical process lies behind the slow-down of SN Ia light curves >900 days after explosion, and, ultimately, fresh constraints on the various SN Ia progenitor and explosion models.
Lean and agile in small- and medium-sized enterprises: Complementary or incompatible?
Authors: Gurahoo Neeshal , Salisbury Roger H. 
Published: May 2018

Background: This study explores the relationship between the implementation of lean supply chain management and the agility of manufacturing small- and medium-sized enterprises (SMEs). Although some studies have suggested that these two approaches are mutually exclusive, other research finds that they may be applied to different parts of the supply chain or may be compatible through the common elements of process integration and supply chain-wide collaboration. Objectives: Through an investigation of two companies at different stages of lean implementation, this study sought to establish which of these paradigms might be applicable in the context of South African SMEs. Method: Semi-structured interviews were conducted with managers at both companies, and the progress towards lean manufacturing was probed. Results: Company B was found to have made considerably more progress towards a lean system than Company A. Neither company had achieved just-in-time purchasing, and this was identified as a challenging aspect for SMEs. Both companies experienced stockouts and long lead times. The volatile nature of their markets indicated a need for greater agility. Company B was found to have a greater potential for speed, flexibility and response. It is proposed that this may be a direct consequence of greater progress in lean implementation. Conclusion: It was concluded that strategies to implement lean are a necessary prelude to achieving an agile enterprise. This article presents a model incorporating the lean principles that SMEs should adopt in order to achieve agility.
Screening for mutation hotspots in Bardet–Biedl syndrome patients from India
Authors: Chandrasekar Sathya Priya , Namboothiri Sheela , Sen Parveen , Sarangapani Sripriya 
Published: May 2018

Background & objectives:
Bardet–Biedl syndrome (BBS) is a genetically heterogeneous autosomal recessive disorder characterized by multiple organ defects involving retina, kidney, liver and brain. Disease-causing mutations in BBS genes narrowed down by homozygosity mapping in small consanguineous and non-consanguineous pedigrees were reported in 80 per cent of the study population. This study was aimed to screen these genes (BBS3, BBS10) and specific exons of BBS genes (BBS1, BBS5, MKKS, BBS9, BBS11 and BBS12) for recurrent mutations in a selected sample of BBS patients.

Methods:
The recurrent mutations in BBS genes were screened in the BBS affected individuals by PCR based direct sequencing. The pathogenicity of the observed mutations were confirmed by co-segregation analysis, screening of healthy unrelated controls and in silico analysis.

Results:
In the 64 BBS patients (44 males, 20 females) were studied, mutations were predominant in BBS10 and ARL6 genes; the c.272T>C; p.(I91T) mutation in ARL6 gene was a recurrent mutation. One novel non-sense mutation c.425T>G; p(L142*) was obtained in BBS5 gene (family BSI-31).

Interpretation & conclusions:

BBS10 gene mutations clustered in exon 2 of the gene suggesting the exon as a probable hotspot for mutations in Indian population. A cost- and time-effective strategy for the molecular diagnosis of BBS was designed based on these results.
C-glycosyl flavone from Urginea indica inhibits proliferation & angiogenesis & induces apoptosis via cyclin-dependent kinase 6 in human breast, hepatic & colon cancer cell lines

Published: May 2018

Background & objectives:
Search for novel compounds beneficial to the treatment of cancer attracts a great deal of attention. We earlier demonstrated the isolation of 5,7-dihydroxy-2-[4’-hydroxy-3’-(methoxymethyl)phenyl]-6-C-β-glucopyranosyl flavone, a novel C-glycosyl flavone from Urginea indica bulb. The present study was undertaken to investigate the effect of this novel compound on human normal epithelial and breast, hepatic and colon cancer cell lines.

Methods:
The maximum non-toxic concentration (MNTC) and cytotoxicity of C-glycosyl flavone were assayed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT). Cell cycle was analyzed by flow cytometry. Docking studies were performed to predict possible targets. Levels of cyclin-dependent kinase 1 (CDK1) and CDK6, Bcl2 and BAX and cytochrome c were quantified by specific ELISA. Mitochondrial membrane potential was determined using JC-1 dye. Apoptosis was quantified by Annexin V ELISA method.

Results:
Flow cytometry analysis demonstrated G0/G1 arrest. In silico docking studies predicted CDK1 and CDK6 as a possible target of C-glycosyl flavone. In vitro study confirmed CDK6 as the main target in C-glycosyl flavone-treated cancer cell lines. C-glycosyl flavone treatment also induced membrane blebbing, chromatin fragmentation and nucleosome formation. C-glycosyl flavone treatment caused marked loss of mitochondrial membrane potential, decrease in Bcl2/BAX ratio and activation of caspase-3 and release of caspase-9 and cytochrome c. In addition, C-glycosyl flavone inhibited the tumour-induced angiogenesis and reduced the vascular endothelial growth factor levels. Similarly, CDK6 inhibitor significantly inhibited proliferation and angiogenesis and induced apoptosis in tested cell lines.

Interpretation & conclusions:
The results indicate that C-glycosyl flavone may exert induction of apoptosis, cell cycle arrest and inhibition of angiogenesis via CDK6. Thus, targeting CDK6 using C-glycosyl flavone may serve as a novel therapeutic approach for the treatment of breast, hepatic and colon cancers.
La relación entre el consumo de medios digitales, la participación y la eficacia política. Un estudio sobre los jóvenes universitarios en Colombia
Authors: Barredo Ibáñez Daniel , Garza Montemayor Daniel Javier , Dias Castillo Dania Lorena 
Published: May 2018

La participación política es esencial para la consolidación democrática, dado que, mediante el involucramiento social, la ciudadanía puede alcanzar consensos y desarrollar deliberaciones públicas. Esto es especialmente importante en Colombia, cuya sociedad se ha visto envuelta tanto en un conflicto armado durante más de cinco décadas, como asolada por las mafias asociadas al narcotráfico, la brecha económica y la falta de presencia del Estado en algunas regiones, entre otras. Metodología: A través de una encuesta a 581 jóvenes universitarios colombianos, hemos evaluado la relación entre cuatro categorías que pueden ser determinantes para la calidad democrática, como son el consumo de medios digitales, la participación en línea y fuera de línea y la eficacia política. Resultados y conclusiones: En los resultados, además de un vínculo entre las variables indicadas, observamos un bajo consumo de medios tradicionales, así como una falta de participación –en línea y fuera de línea-, en los estudiantes consultados.
El periodismo narrativo español y latinoamericano: influencias, temáticas, publicaciones y puntos de vista de una generación de autores
Authors: Palau-Sampio Dolors , Cuartero-Naranjo Antonio 
Published: May 2018

El periodismo narrativo ha experimentado un auge importante en Latinoamérica, al calor del llamado boom de la crónica latinoamericana. A nivel más modesto, en el ámbito español, ha logrado un particular impulso de la mano de editoriales especializadas. El objetivo de este trabajo es contrastar puntos de vista, temáticas, influencias y publicaciones entre periodistas españoles y latinoamericanos. Metodología. El estudio parte de entrevistas en profundidad a 22 destacados representantes del periodismo narrativo de España, Argentina y Chile. Resultados y conclusiones. Pese a la diversidad de denominaciones, los periodistas de ambas latitudes coinciden al identificar las claves del género y apuntan las dificultades para su desarrollo, por la falta de espacios en la prensa convencional, que han absorbido el libro y las revistas. A la versatilidad temática se suman algunas diferencias entre autores españoles y latinoamericanos, tanto al abordar la estructura narrativa como en la reciprocidad de las referencias profesionales.
Cloud condensation nuclei activity of CaCO3 particles with oleic acid and malonic acid coatings

Published: May 2018

Abstract. Condensation of carboxylic acids on mineral particles leads to
coatings and impacts the particles' potential to act as cloud
condensation nuclei (CCN). To determine how the CCN activity of
mineral particles is impacted by carboxylic acid coatings, the CCN
activities of CaCO3 particles and CaCO3 particles
with oleic acid and malonic acid coatings were compared in this
study. The results revealed that small amounts of oleic acid coating
(volume fraction (vf) ≤4.3 %) decreased the CCN activity
of CaCO3 particles, while more oleic acid coating (vf ≥16 %) increased the CCN activity of CaCO3
particles. This phenomenon has not been reported before. In contrast, the CCN activity of CaCO3 particles coated with
malonic acid increased with the thickness of the malonic acid
coating (vf =0.4–40 %). Even the smallest amounts of malonic
acid coating (vf =0.4 %) significantly enhanced the CCN
activity of CaCO3 particles from κ=0.0028±0.0001 to κ=0.0123±0.0005. This indicates that a small
amount of water-soluble organic acid coating may significantly
enhance the CCN activity of mineral particles. The presence of water
vapor during the coating process with malonic acid additionally
increased the CCN activity of the coated CaCO3 particles,
probably because more CaCO3 reacts with malonic acid when
sufficient water is available.
Landscape analysis of soil methane flux across complex terrain
Authors: Kaiser Kendra E. , McGlynn Brian L. , Dore John E. 
Published: May 2018

Abstract. Relationships between methane (CH4) fluxes and environmental conditions
have been extensively explored in saturated soils, while
research has been less prevalent in aerated soils because of the relatively
small magnitudes of CH4 fluxes that occur in dry soils.
Our study builds on previous carbon cycle research at Tenderfoot
Creek Experimental Forest, Montana, to identify how environmental conditions
reflected by topographic metrics can be leveraged to estimate watershed scale
CH4 fluxes from point scale measurements. Here, we measured soil
CH4 concentrations and fluxes across a range of landscape positions (7 riparian, 25 upland),
utilizing topographic and seasonal (29 May–12 September) gradients to examine the relationships between
environmental variables, hydrologic dynamics, and CH4 emission and
uptake. Riparian areas emitted small fluxes of CH4 throughout the study
(median: 0.186 µg CH4–C m−2 h−1) and uplands increased
in sink strength with dry-down of the watershed (median: −22.9 µg CH4–C m−2 h−1). Locations with volumetric water content (VWC)
below 38 % were methane sinks, and uptake increased with decreasing VWC.
Above 43 % VWC, net CH4 efflux occurred, and at intermediate VWC net
fluxes were near zero. Riparian sites had near-neutral cumulative seasonal
flux, and cumulative uptake of CH4 in the uplands was significantly
related to topographic indices. These relationships were used to model the
net seasonal CH4 flux of the upper Stringer Creek watershed (−1.75 kg CH4–C ha−1). This spatially distributed estimate was 111 % larger
than that obtained by simply extrapolating the mean CH4 flux to the
entire watershed area. Our results highlight the importance of quantifying
the space–time variability of net CH4 fluxes as predicted by the
frequency distribution of landscape positions when assessing watershed scale
greenhouse gas balances.
The Environmental Conditions of Agency: John Dewey and Jane Jacobs on Diversity and the Modern Urban Landscape
Authors: Howell Whitney 
Published: May 2018

ABSTRACT
In this article, I examine the formative relation between individuals and their environment to consider more specifically how urban environments support individual agency. I draw on John Dewey's account, in Individualism, Old and New (1930), of the transformation of American society through rapid industrialization, the rise of corporate culture, and their effects on individual psychology. Dewey's analysis demonstrates the role of environmental conditions in motivating and sustaining individual development and thus draws on his earlier work in Democracy and Education (1916), in which he identifies environmental features of democratic societies—namely, diversity and openness to change—as crucial for individual growth and well-being. Drawing on Jane Jacobs's monumental work The Death and Life of Great American Cities (1961), I show how urban environments enact the democratic ideals Dewey identifies. Following Dewey's and Jacobs's accounts, I argue that the psychological health of city inhabitants—and, correspondingly, the vitality of the cities where they live—depends on their dynamic relation to an environment that values diversity and offers opportunities for growth. It is only in the context of such a relation—that is, as embedded in and supported by an environment that reflects their own possibilities—that individuals can realize agency.
Royce on Self and Relationships: Speaking to the Digital and Texting Self of Today
Authors: Kegley Jacquelyn Ann 
Published: May 2018

ABSTRACT
Is Internet and phone technology impacting our understanding of “self” and changing the way we relate to each other? Have we given up a strong self-identity for self-presentation and self-promotion? As anonymous individuals we are losing our inhibitions and also a sense of ethical commitment and responsibility. This essay argues that Josiah Royce's philosophy provides a rich resource for addressing these problems. He understood how technology brings about changes in conceptions of self and of relationships. He experienced firsthand the changes in social relations and self-understanding brought about by the mining technology of his time, and he recognized the dangers that media technology posed, including the leveling of opinions and the loss of individuality. More importantly, his theory of self and self-development is fruitful in addressing the problems posed by interaction in a disembodied Internet world, and his theory of community speaks to the isolation and loneliness promoted by the Internet and the starving of our capacity to communicate face-to-face fostered by the new phone technology.
Radical Holiness Mission Theory in the Church of the Brethren Experience
Authors: Kostlevy William 
Published: May 2018

ABSTRACT
The Radical Holiness movement deeply impacted not only emerging Holiness and Pentecostal denominations but existing churches. This impact was especially felt by the so-called Peace Churches of Friends, Mennonites, and the Church of the Brethren. This essay explores the understudied Brethren experience. It describes Brethren mission theory in the Social Gospel era and its relationship to currents in the broader Protestant world. While denominational mission board members followed a more moderate course, pastors and missionaries nurtured at Bethany Bible School, later Bethany Theological Seminary, drew on Radical Holiness currents. The most important was Anna Beahm Mow, missionary to India, professor, and popular evangelical author. For Mow the essence of the Christian or surrendered life was living a life devoted to and shaped by Christ, not support for programs or institutions.
Of Exterior and Exception: Latin American Rhetoric, Subalternity, and the Politics of Cultural Difference
Authors: Cortez José M. 
Published: May 2018

ABSTRACTThe question of non-Western difference has come to feature prominently across the field of comparative rhetoric, where it is often presupposed that an irreducible difference separates Western from non-Western rhetorical and cultural production. It is on the basis of this presupposition that critics have established a politics of comparative inquiry, whereby restituting the pure consciousness of a non-Western subaltern subject is understood to subvert the hegemony of Western thought. But what exactly is the nature of this difference? In this article I examine the recent turn toward Latin America in the field of comparative rhetoric to argue that this presupposition serves as a constitutive topos—that the object of Latin America is invented rhetorically in the very act of comparative inquiry—and that this presupposition yields a political impasse that the field has yet to think through. Drawing on recent work in Latin American studies, I argue for a rearticulated notion of subalternity as a methodological approach for dealing with this impasse.
Rhetorical Action inRektoratsrede: Calling Heidegger'sGefolgschaft
Authors: Sharpe Matthew 
Published: May 2018

ABSTRACTThis article analyzes Heidegger's rhetoric in his most famous political address, the Rektoratsrede, which he delivered at the University of Freiburg on 27 May 1933. After I set out the political and philosophical kairos of the Rektoratsrede by drawing on Heidegger's contemporary lectures, letters, and Ponderings, in part 2 I use classical rhetorical resources and Heidegger's philosophy of temporality in Sein und Zeit (1927) to analyze the arrangement of his speech. In part 3, I examine two key National Socialist terms in the speech's climax. In part 4, I consider Heidegger's elocutio—his artful use of charged figures of speech and thought in the Rektoratsrede—in more detail. Concluding remarks reflect on the value and limits of the analysis in the context of debates about Heidegger's politics and its imbrication with his thought.
Estilística Léxica e o Discurso Jurídico nas Sentenças da Vara Maria da Penha no Combate à Violência Doméstica Contra a Mulher
Authors: Canezin Claudete Carvalho 
Published: May 2018

É o presente artigo um estudo acerca da estilística léxica nos discursos jurídicos das sentenças que envolvem a violência contra a mulher na Vara Maria da Penha, na comarca de Londrina-Paraná. Assim como o Direito, a linguagem é uma instituição social reguladora das relações humanas, funcionando, portanto, como mediadora entre a pessoa e a realidade cotidiana que a cerca. Infelizmente, em muitas situações, a linguagem é utilizada de forma nociva, donde é possível vislumbrar itens lexicais e avaliativos utilizados de forma pejorativa, tal como acontece em músicas, propagandas, e até mesmo em piadinhas de mau gosto que circulam nas redes sociais e que acabam camuflando a agressividade contra a mulher, violência esta que não precisa ser especificamente física, mas também moral e psicológica, e, neste contexto, as palavras são armas poderosas. A fim de coibir a violência contra a mulher, foi editada a Lei nº 11.340/2006, conhecida como Lei Maria da Penha. A partir de sua promulgação, todos os processos envolvendo violência de gênero passaram a tramitar nos Juizados Especiais Criminais da Varas Maria da Penha. Pretende-se, pois, através da análise da estilística léxica, voltar olhares e trazer para a pauta do estudo a análise de itens lexicais e avaliativos comuns no discurso jurídico das sentenças dos processos que tramitam na Vara Maria da Penha, inclusive, com a transcrição de parte dos relatórios, preservando as partes envolvidas por se tratar de segredo de justiça.
