The Southern Dative Presentative Meets Mechanical Turk
Authors: Wood Jim , Horn Laurence , Zanuttini Raffaella , Lindemann Luke
Published: November 2015

This article introduces the southern dative presentative, an understudied construction that varies across speakers of American English. The authors discuss similarities and differences between this construction and the better-studied personal dative construction and compare the Southern dative presentative with similar constructions cross-linguistically. They then present the results of a nationwide acceptability judgment survey administered on Amazon Mechanical Turk. The results show that Southern dative presentatives are alive and well in Southern dialects of American English. In the process, they also illustrate the usefulness of Amazon Mechanical Turk (and similar crowdsourcing platforms) for the study of dialect variation in the domain of syntax.

The Mitogen-Activated Protein kinase, MAP3K1, plays an important role in a number of cellular processes, including epithelial migration during eye organogenesis. In addition, studies in keratinocytes indicate that MAP3K1 signaling through JNK is important for actin stress fibre formation and cell migration. However, MAP3K1 can also act independently of JNK in the regulation of cell proliferation and apoptosis.

We have identified a mouse mutant, goya, which exhibits eyes-open-at-birth and microphthalmia phenotypes. In addition, these mice also have hearing loss. The goya mice carry a splice site mutation in the Map3k1 gene. We show that goya and kinase-deficient Map3k1 homozygotes initially develop supernumerary cochlear outer hair cells (OHCs) that subsequently degenerate, and a progressive profound hearing loss is observed by 9-weeks of age. Heterozygote mice also develop supernumerary OHCs, but no cellular degeneration or hearing loss is observed. MAP3K1 is expressed in a number of inner ear cell types, including outer and inner hair cells, stria vascularis and spiral ganglion. Investigation of targets downstream of MAP3K1 identified an increase in p38 phosphorylation (Thr180/Tyr182) in multiple cochlear tissues. We also show the extra OHCs do not arise from aberrant control of proliferation via p27KIP1.

The identification of the goya mutant reveals a novel signaling molecule involved with hair cell development and survival. Mammalian hair cells do not have the ability to regenerate after damage, which can lead to irreversible sensorineural hearing loss. Given the observed goya phenotype, and the many diverse cellular processes MAP3K1 is known to act upon, further investigation of this model may help elaborate upon the mechanisms underlying sensory hair cell specification, and pathways important for their survival. In addition, MAP3K1 is revealed as a new candidate gene for human sensorineural hearing loss.
CDK9 and its repressor LARP7 modulate cardiomyocyte proliferation and response to injury in the zebrafish heart

Published: November 2015

Cyclin dependent kinase (Cdk)9 acts through the positive transcription elongation factor-b (P-TEFb) complex to activate and expand transcription through RNA polymerase II. It has also been shown to regulate cardiomyocyte hypertrophy, with recent evidence linking it to cardiomyocyte proliferation. We hypothesised that modification of CDK9 activity could both impair and enhance the cardiac response to injury by modifying cardiomyocyte proliferation. Cdk9 expression and activity were inhibited in the zebrafish (Danio rerio) embryo. We show that dephosphorylation of residue Ser2 on the C-terminal domain of RNA polymerase II is associated with impaired cardiac structure and function, and cardiomyocyte proliferation and also results in impaired functional recovery following cardiac laser injury. In contrast, de-repression of Cdk9 activity, through knockdown of La-related protein (Larp7) increases phosphorylation of Ser2 in RNA polymerase II and increases cardiomyocyte proliferation. Larp7 knockdown rescued the structural and functional phenotype associated with knockdown of Cdk9. The balance of Cdk9 and Larp7 plays a key role in cardiomyocyte proliferation and response to injury. Larp7 represents a potentially novel therapeutic target to promote cardiomyocyte proliferation and recovery from injury.
On the Verges of Overconfidence
Authors: Malmendier Ulrike , Taylor Timothy
Published: November 2015

This symposium provides several examples of overconfidence in certain economic contexts. Michael Grubb looks at “Overconfident Consumers in the Marketplace.” Ulrike Malmendier and Geoffrey Tate consider “Behavioral CEOs: The Role of Managerial Overconfidence.” Kent Daniel and David Hirshleifer discuss “Overconfident Investors, Predictable Returns, and Excessive Trading.” A number of insights and lessons emerge for our understanding of markets, public policy, and welfare. How do firms take advantage of consumer overconfidence? Might government attempts to rule out such practices end up providing benefits to some consumers but imposing costs on others? How are empirical measures of CEO overconfidence related to investment and the capital structure of firms? Can overconfidence among at least some investors help to explain prominent anomalies in stock markets like high levels of trading volume and certain predictable patterns in stock market returns?
Behavioral CEOs: The Role of Managerial Overconfidence
Authors: Malmendier Ulrike , Tate Geoffrey
Published: November 2015

In this paper, we provide a theoretical and empirical framework that allows us to synthesize and assess the burgeoning literature on CEO overconfidence. We also provide novel empirical evidence that overconfidence matters for corporate investment decisions in a framework that explicitly addresses the endogeneity of firms' financing constraints.
Overconfident Investors, Predictable Returns, and Excessive Trading
Authors: Daniel Kent , Hirshleifer David
Published: November 2015

The last several decades have witnessed a shift away from a fully rational paradigm of financial markets toward one in which investor behavior is influenced by psychological biases. Two principal factors have contributed to this evolution: a body of evidence showing how psychological bias affects the behavior of economic actors; and an accumulation of evidence that is hard to reconcile with fully rational models of security market trading volumes and returns. In particular, asset markets exhibit trading volumes that are high, with individuals and asset managers trading aggressively, even when such trading results in high risk and low net returns. Moreover, asset prices display patterns of predictability that are difficult to reconcile with rational-expectations–based theories of price formation. In this paper, we discuss the role of overconfidence as an explanation for these patterns.

Authors: Johar Saima , Irfan Shazia , Ahmed Shehnaz Sher , Jabeen Rukhsana
Published: November 2015

Rosmarinus officinalis is a medicinal plant which belongs to family Lamiaceae. It is an evergreen bush. It was analyzed for its phytochemical constitution and antibacterial activity. For this purpose flowers, leaves and stem of aqueous and methanolic extracts were used. The tests of phytochemical screening showed that flavonoids, terpenoids, reducing sugar and saponins were present in different concentrations, while tannin was absent in all parts of plant. The antibacterial activity was determined against E. coli with different concentrations (i-e 0.5gm, 1gm and 1.5gm) kept for 24 hours and 48 hours duration. The results showed that the highest mean inhibition zone was observed in the methanolic extracts of leaves 1.5gm kept for 48 hours (28.6 ± 4.261mm).In the stem the methanolic extracts showed the highest inhibition zone with the concentration of 1.5gm (13.4 ± 1.624mm) kept for 24 hours. In the flower the highest inhibition zone in methanolic extracts was observed in 1gm (25.4 ± 2.416mm) kept for 48 hours. In the aqueous extracts the highest inhibition zone values were (17.6 ± 4.029mm, 15.8 ± 2.993mm, 14.4 ± 2.33mm) for stem, flower and leaves respectively.

Published: November 2015

Shiny dome-like structures measuring less than 1mm in length were excised aseptically from shoot tip buds of infected of two cassava (Manihot esculenta Crantz) local cultivars (Boma and Mpelo Nlongi) and cultivated in vitro in two types of media with different combination of growth hormone: Murashige and Skoog supplemented of sucrose (20 g/l), Naphtalenacetic acid (NAA, 10 Î¼M), Ben-zylaminopurine (BAP, 0.66 Î¼M) as well as Gibberellic acid (GA3, 0.1 Î¼M) with 80 mg/l of Adenine sulphate and MS-free growth regulators. After four weeks, data were scored: 29.5% responding explant with callus formation and 20.5% responding explants to shoot development in the medium with growth regulators for the cultivar Boma whereas the cultivar Mpelo-Nlongi presented 5.7% and 25.7% respectively of callus formation and shoot development. The cultivar Boma presented a tendency more pronounced for the callus formation rather than with the shoot development contrary to the cultivar Mpelo-Nlongi. In regards of this experiment, it was shown that the media composition and genotype are essential factors, which influence in vitro growth, mainly the shoot development, in the culture of meristems for cassava local accessions.

Published: November 2015

This paper attempts to elaborate current existence of Islamic Communication curriculum, particularly Dakwah Jurnalism as one of the Islamic communication education pillars, either on state or private Islamic universities in Indonesia. Departing from an explanation of empirical phenomenon of the technological revolution and globalization of communication that broughtsignificant impacts on the communicationindustry and social-global behavior, this paper wants to criticize backwardness content of DakwahJournalism curriculum that failed to adopt both dynamics as genial formulation to form new scholar competency of Islamic Communications in modern world. The curriculum focus for journalism ethical values only shows another fact that there is a weakness on scientific exploration of the journalism science in Islamic tradition. This paper will be concluded with myanalysis for the differences of vision and mission addressed by Islamic Communication Departments (KPI) in PTAI that aggravate above conditions. This problem represents only one example of the complexity of the problems in the PTAI teaching system amidst of migration policy from IAIN into State Islamic University(UIN). To establish competitive graduates with holistic competency, it is necessary for PTAI managers to develop new framework, vision, mission and curriculum content at large. The initiatives can be started by changing Dakwah Journalism curriculum.
Teaching material based on biomechanical evidence: ‘high-jump hurdles’ for improving fundamental motor skills
Authors: Otsuka Mitsuo , Otomo Satoshi , Isaka Tadao , Kurihara Toshiyuki , Akutsu Chihiro
Published: November 2015

Study aim: the purpose of this study has been to develop teaching materials to help improve junior high school students’ fundamental ability to repeatedly run and jump with a high and far-reaching travelling motion and to confirm the effectiveness of a new unit using teaching materials that are experimental in comparison to a conventional unit.

Materials and methods: one unit emphasized the conventional approach. This unit aims to improve the ability to step over hurdles. To help improve this ability, a ‘step-up hurdle’ was used as the conventional teaching material. This task focused on reducing the up-and-down motion using three hurdles whose height was set lower than those used in a competitive hurdle run. The other unit aims to improve the ability to jump high and far over hurdles. To help improve this ability, ‘high-jump hurdles’ were developed and used as the teaching material. The motor skill task was to clear three hurdles without knocking a hurdle down, with the hurdle height set as high as possible. Such conventional and new units were used for a group of 25 girls and a group of 18 girls in a junior high school (CON and EXP, respectively) and were conducted during six lessons.

Results: EXP’s high-jump hurdle scores significantly increased throughout the advanced lessons. While CON did not significantly improve its hurdle running times in a post-test, there was a significant improvement in EXP. Although CON did not significantly lengthen the horizontal clearance distance from take-off to landing in the post-test, there was a significant lengthening in EXP.

Conclusions: these findings suggest that new teaching material for teaching hurdling in physical education which aims to improve the ability to jump high and far over hurdles improves hurdle running time and improves the fundamental ability to repeat running and jumping travelling motor skills in contrast to traditional materials.
Phylogeny and morphology ofParviphycus myriocladus(Børgesen) comb. nov. (Gelidiales, Rhodophyta) from Asian waters
Authors: Boo Ga Hun , Cai Yixiong , Kim Jung Yeon , Boo Sung Min
Published: November 2015

Plants of the red algal genusParviphycusare typically diminutive and often occur in mixed stands with other turf species, leading to considerable difficulty in locating them in the field. Once sorted, identification to genus and species is challenging because of their lack of conspicuous diagnostic features. Examination of the type specimen and fresh collections ofGelidiella myriocladafrom Singapore revealed that this species may be incorrectly classified toGelidiella. To test the taxonomic position ofG.myrioclada, phylogenetic analyses usingrbcL andcox1 data were performed.Parviphycuscomprised two clades that corresponded to geographical distributions in the Atlantic and the Indo-Pacific. In all analyses,G. myriocladawas consistently resolved in the Indo-PacificParviphycusclade, along withParviphycus antipaeandParviphycussp. Based on morphology,G.myriocladashows subapical growth and tetrasporangial characteristics that are unique toParviphycus. We therefore, propose the assignment ofG. myriocladaasParviphycusmyriocladus(Børgesen) comb. nov.
CFD Study of the Hydrodynamics of Slug Flow Systems: Interaction between Consecutive Taylor Bubbles
Authors: Araújo J. D. P. , Miranda J. M. , Campos J. B. L. M.
Published: November 2015

Slug flow is one of the most frequently occurring multiphase flow patterns in industrial processes. A deep knowledge of its fundamentals is necessary to accurately model not only the fluid flow but also reaction and heat and mass transfer in several operation units. A numerical study is reported on the dynamics of slug flow, under laminar regime, in vertical columns of stagnant and co-current Newtonian and non-Newtonian liquids (shear-thickening and shear-thinning). A CFD package (Ansys FLUENT) with the VOF methodology was applied to simulate the flow of individual and pairs of consecutive Taylor bubbles. The behaviour of the most relevant hydrodynamic features with the approach of the trailing bubble towards the leading one is addressed, with particular emphasis to the role of the liquid rheology and flow configuration. The main results presented are the velocity ratio curves between consecutive bubbles, the variation of the bubbles shape, and the axial velocity and viscosity fields in the surrounding liquid. This bubble-bubble interaction data can be a keystone to improve and complement continuous slug flow simulators used for very long columns.

Single photon avalanche detectors: prospects of new quenching and gain mechanisms
Authors: Hall David , Liu Yu-Hsin , Lo Yu-Hwa
Published: November 2015

While silicon single-photon avalanche diodes (SPAD) have reached very high
detection efficiency and timing resolution, their use in fibre-optic
communications, optical free space communications, and infrared sensing and
imaging remains limited. III-V compounds including InGaAs and InP are the
prevalent materials for 1550 nm light detection. However, even the most
sensitive 1550 nm photoreceivers in optical communication have a sensitivity
limit of a few hundred photons. Today, the only viable approach to achieve
single-photon sensitivity at 1550 nm wavelength from semiconductor devices is to
operate the avalanche detectors in Geiger mode, essentially trading dynamic
range and speed for sensitivity. As material properties limit the performance of
Ge and III-V detectors, new conceptual insight with regard to novel quenching
and gain mechanisms could potentially address the performance limitations of
III-V SPADs. Novel designs that utilise internal self-quenching and negative
feedback can be used to harness the sensitivity of single-photon detectors,while
drastically reducing the device complexity and increasing the level of
integration. Incorporation of multiple gain mechanisms, together with
self-quenching and built-in negative feedback, into a single device also hold
promise for a new type of detector with single-photon sensitivity and large
dynamic range.
Growth and characterization of R(O,F)BiS2 (R = La, Ce, Pr, Nd) superconducting single crystals
Authors: Nagao Masanori
Published: November 2015

R(O,F)BiS2 (R: La, Ce, Pr, Nd) superconducting single crystals with different F concentrations are grown using a CsCl/KCl flux. The obtained 1-2 mm-sized single crystals have a plate-like shape and are cleavable along the ab-plane. The crystal structure is tetragonal of space group P4/nmm (#129). The as-grown single crystals exhibit superconductivity at around 3–5 K. The superconducting transition temperature increases with decreasing the ionic radius of the R element. The superconducting anisotropies of the R(O,F)BiS2 single crystals are estimated to be 30–60 according to the effective mass model, whereas the anisotropies for Ce(O,F)BiS2 single crystals are 13–21. The c-axis transport measurements of a single crystal of Pr(O,F)BiS2 under a magnetic field parallel to the ab-plane reveal a “lock-in” state attributed to the Josephson vortex flow. Furthermore, the Ce(O,F)BiS2 single crystals exhibit a magnetic order at the temperature range of 5–7 K that apparently coexist with superconductivity below approximately 3 K.
Modelling and Validation of Transmittance from Nanocrystalline Titania film for Photoanodic Action in Dye-Sensitized Solar Cells
Authors: Jyoti Divya
Published: November 2015

A four phase model air/glass/indium doped tin oxide/TiO2 has been studied by modifying Rouard’s model to calculate the final transmittance from TiO2 layer to be used as photoanode in dye-sensitized solar cells. An optical simulation for the reflectance and transmittance has been executed for the constructed nanocrystalline TiO2 films. To validate the theoretical results TiO2 film has been deposited onto indium doped tin oxide (ITO) layer by sol-gel dip coating technique. It has been found that the incident light suffers losses by 5-15% on passage through TiO2 coated ITO layer. Experimentally it has been observed on the basis of efficiency value that meso-nano combination is the best candidate to be used as photoanode in a dye-sensitize solar cell.
Are Aquinas and Whitehead Metaphorical
and Analogical All the Way Down?
Authors: Masson Robert
Published: November 2015

The paper argues from the perspective of a significant strand of interpretation of Aquinas and
from insights in cognitive linguistics that a fruitful dialogue between Whitehead and Thomism needs
to take into account that metaphysics and talk about God are metaphorical and analogical all the way
down. Cognitive linguistics provides an explanatory scheme for explaining how Aquinas’s tectonic use
of analogy shifts the ground of our conventional fields of meanings to create space to conceptualize what
otherwise would be beyond grasp and to make inferences possible that otherwise would be unthinkable.
The essay concludes with a question, admittedly from a particular trajectory of Thomism and cognitive
linguistics, about whether Whitehead’s conception of God adequately accounts for the radically
metaphorical “imaginative leap” entailed in the Christian conception of God.
Phosphene perception is due to the ultra-weak photon emission produced in various parts of the visual system: glutamate in the focus
Authors: Császár Noémi , Scholkmann Felix , Salari Vahid , Szőke Henrik , Bókkon István
Published: November 2015

Phosphenes are experienced sensations of light, when there is no light causing them. The physiological processes underlying this phenomenon are still not well understood. Previously, we proposed a novel biopsychophysical approach concerning the cause of phosphenes based on the assumption that cellular endogenous ultra-weak photon emission (UPE) is the biophysical cause leading to the sensation of phosphenes. Briefly summarized, the visual sensation of light (phosphenes) is likely to be due to the inherent perception of UPE of cells in the visual system. If the intensity of spontaneous or induced photon emission of cells in the visual system exceeds a distinct threshold, it is hypothesized that it can become a conscious light sensation. Discussing several new and previous experiments, we point out that the UPE theory of phosphenes should be really considered as a scientifically appropriate and provable mechanism to explain the physiological basis of phosphenes. In the present paper, we also present our idea that some experiments may support that the cortical phosphene lights are due to the glutamate-related excess UPE in the occipital cortex.
Elementary triangular matrices and inverses of k-Hessenberg and triangular matrices

Published: November 2015

We use elementary triangular matrices to obtain some factorization, multiplication, and inversion
properties of triangular matrices. We also obtain explicit expressions for the inverses of strict k-Hessenberg
matrices and banded matrices. Our results can be extended to the cases of block triangular and block Hessenberg
matrices. An n × n lower triangular matrix is called elementary if it is of the form I + C, where I is the
identity matrix and C is lower triangular and has all of its nonzero entries in the k-th column,where 1 ≤ k ≤ n.
A Comprehensive Theoretical Investigation of the Molecular Properties of Methyl Bromide (CH3Br)
Authors: Yu Ang-Yang , Efil Kürşat , Yang Rui , Hu Qing-Miao
Published: November 2015

The properties of the ground and the lowest excited state of methyl bromide (CH3Br) have been studied with and without inclusion of the solvent effects in this work. The geometric parameters, energies, and frequencies of the ground state and the triplet state are calculated by using the MP2(full)/6-311++G** level of theory. The vertical excitation for the singlet state is also investigated. It is found that the theoretical results performed by the TDDFT/B3P86/6-311++G** method are in the best agreement with the experimental results. In addition, the dissociation energy of CH3Br molecule is computed at MP2(full)/6-311++G** level of theory for the gas phase and in water. The ionisation potential (IP), electron affinity (EA), electronegativity (χ), electrophilicity index (ω), hardness (η), softness (S), and chemical potential (μ) values are calculated from HOMO-LUMO energies both in the gas phase and in solvent (water). These theoretical results could serve as a guide for future experimental investigations.

Authors: Wang Ke , Feng Xu , Feng Wenlin , Shi Shasha , Li Yao , Zhang Chao
Published: November 2015

Fe3+ undoped and doped CaWO4: Pr3+ phosphors have been successfully synthesised by using the solid-state reaction method. The products were characterised by powder X-ray diffraction (XRD), photoluminescence (PL) and fluorescence lifetime testing techniques, respectively. The mean crystallite size (50.7 nm) of CaWO4: Pr3+ is obtained from powder XRD data. PL spectra of both Fe3+ undoped and doped CaWO4: Pr3+ phosphors exhibit excitation peaks at 214, 449, 474, and 487 nm under monitor wavelength at 651 nm, and emission peaks at 532, 558, 605, 621, 651, 691, 712, and 736 nm under blue light (λ
em=487 nm) excitation. The effect of trace Fe3+ on luminescence properties of CaWO4: Pr3+ phosphor is studied by controlling the doping concentration of Fe3+. The results show that radioactive energy transfers from luminescence centre Pr3+ to quenching centre Fe3+ occurred in Fe3+ doped CaWO4: Pr3+ phosphors. With the increasing concentration of Fe3+, the energy transfer from Pr3+ to Fe3+ is enhanced, and the emission intensity of CaWO4: Pr3+ will be lower. The decay times (5.22 and 4.99 μs) are obtained for typical samples Ca0.995WO4: Pr3+
0.005 and Ca0.99275WO4: Pr3+
0.005, Fe3+
0.00225, respectively. This work shows that nonferrous phosphors can improve the luminescent intensity of the phosphors.
Mechanisms of fibroblast growth factor signaling in the ovarian follicle
Authors: Price Christopher A
Published: November 2015

Fibroblast growth factors (FGFs) have been shown to alter growth and differentiation of reproductive tissues in a variety of species. Within the female reproductive tract, the effects of FGFs have been focused on the ovary, and the most studied one is FGF2, which stimulates granulosa cell proliferation and decreases differentiation (decreased steroidogenesis). Other FGFs have also been implicated in ovarian function, and this review summarizes the effects of members of two subfamilies on ovarian function; the FGF7 subfamily that also contains FGF10, and the FGF8 subfamily that also contains FGF18. There are data to suggest that FGF8 and FGF18 have distinct actions on granulosa cells, despite their apparent similar receptor binding properties. Studies of non-reproductive developmental biology also indicate that FGF8 is distinct from FGF18, and that FGF7 is also distinct from FGF10 despite similar receptor binding properties. In this review, the potential mechanisms of differential action of FGF7/FGF10 and FGF8/FGF18 during organogenesis will be reviewed and placed in the context of follicle development. A model is proposed in which FGF8 and FGF18 differentially activate receptors depending on the properties of the extracellular matrix in the follicle.

An investigation of a cluster of cervical herniated discs among container truck drivers with occupational exposure to whole‐body vibration: Fan‐Yun Lan, et al. Department of Occupational and Environmental Medicine, National Cheng Kung University Hospital, Taiwan

Objective

This study aimed to determine if occupational exposure to whole‐body vibration is associated with cervical intervertebral disc herniation among container truck drivers.

Methods

We conducted a walk‐through survey among container truck drivers and unexposed workers. We also measured the vibration hazard of the container truck over the driver's back and seat when the driver was loading a container and driving the loaded truck.

Results and Discussion

Among the 38 workers interviewed, 32 were container truck drivers. Four of them reported cervical herniated discs, and all of these individuals were container truck drivers with a job tenure of greater than 10 years. Self‐reported cervical herniated disc, nuchal pain, nocturia, arm/forearm weakness, arm/forearm numbness, and finger numbness were significantly more prevalent as the driver's duration of exposure increased (all p values of test for trend <0.05). The vibration of the truck during and after loading a container was considered the main cause of herniated disc. When a container truck was driven with a loaded container, both the vertical and horizontal vibrating acceleration over the seat and back sites exceeded the 8‐hr exposure level based on the ISO 2631‐1 criteria. The transient vibration dose values (VDVs) measured during misaligned or unsmooth loading operations were usually greater than the upper bounds of the health guidance caution zone for the 8‐hr VDV.

Conclusions

Our investigation disclosed a cluster of cervical intervertebral disc herniation that was associated with the vibration hazard during long‐term container truck driving under full load and possibly aggravated by misaligned loading operations.

Beyond the Digital Diaspora
Authors: Ó Briain Lonán
Published: November 2015

This article examines attempts by American Hmong to turn the thriving Hmong digital diaspora into a sustainable offline musical community. The Hmong, an ethnic group of five million people spread across five continents, have embraced YouTube as a primary source for Hmong music recordings. Online research on Hmong users with the aid of YouTube Analytics is informed by extensive periods of fieldwork with the Hmong in Vietnam and shorter encounters with Hmong in the US since 2007. The Hmong Music Festival, held in Fresno, California in 2012 and 2013, is used as a case study of attempts by American Hmong to build on the increasingly prominent digital diaspora to form an offline community of shared musical and cultural practices associated with their ethnicity. The cancellation of the festival in 2014 resulted in an online backlash that has challenged the continued existence of this annual event. The research shows that despite the vibrancy of online Hmong musical networks and the potential for developing offline connections, the Hmong digital diaspora are reaching the state of an enhanced imagined community in the cyber world, which may not be able to mobilise into a sustainable offline movement due to irreconcilable local and translocal differences.
Le Mystère de Marcel Cellier
Authors: Sweers Britta
Published: November 2015

Marcel Cellier (1925–2013) played a key role in early world music due to his influential recordings of Le Mystère des Voix Bulgares choirs and of the Romanian pan-flutist Gheorghe Zamfir. As Cellier remained a “footnote” in scholarly literature, the article first provides a biographical sketch, before casting a look at the history of world music before the term was established in 1987. Cellier’s work was significant in providing access to Eastern European music during the Cold War. As will be discussed in the third part of the article, this transfer process was not only intertwined with specific and differently perceived concepts of “authenticity”, it was also tied to a specific mediatized situation.

Blurring Borders: the self, the wanderer and the observer in Edgar Allan Poe, Charles Baudelaire and Machado de Assis
Authors: Philippov Renata
Published: November 2015

Much has been published and discussed in relation to Edgar Allan Poe’s and Charles Baudelaire’s intertextual dialogues, as well as to the French reception of Poe’s writings and aesthetic theories through Baudelaire’s translations and essays. Likewise, there have been several studies in Brazil comparing Poe’s and Brazilian writer Machado de Assis’ short stories and individual aesthetic theories, as well as studies regarding Baudelaire’s aesthetic reception in 19th century Brazilian literature. However, despite some academic studies and papers in Brazil referring more closely to their literary projects and their possible intertextual bindings, a deeper study into how Machado de Assis may have actually read and subverted Poe’s writings so as to fit it within his own framework and thus help foster his project of defending the formation of a national literary identity still needs to be carried out. The same may be said about both Baudelaire’s role in Poe and Machado de Assis’ literary encounter and Machado de Assis’ reception of Baudelaire’s aesthetic theories and poetics.

In this paper, therefore, I want to take a transatlantic voyage while addressing the question of how Machado de Assis may have actually incorporated and, paradoxically, subverted Poe’s and Baudelaire’s imagery, topoi and aesthetics into his own literary project. Two broad aspects regarding the three authors’ writings will be tackled: the universe of mind and man’s isolation vis-à-vis society, within the scope of the fantastic as a genre. To do so, I will focus on “Só!” [Alone/Lonely], a short-story published by Machado de Assis in 1885, thus aiming at addressing how the self, the wanderer and the observer appear in this story and how they dialogue with the same figures in some of Poe’s and Baudelaire’s writings.

Renovascular disease (RVD) induces renal microvascular (MV) rarefaction that drives progressive kidney injury. In previous studies, we showed that renal vascular endothelial growth factor (VEGF) therapy attenuated MV damage, but did not resolve renal injury at practical clinical doses. To increase the bioavailability of VEGF, we developed a biopolymer-stabilized elastin-like polypeptide (ELP)-VEGF fusion protein and determined its in vivo potential for therapeutic renal angiogenesis in RVD using an established swine model of chronic RVD. We measured single-kidney blood flow (RBF) and GFR and established the degree of renal damage after 6 weeks of RVD. Pigs then received a single stenotic kidney infusion of ELP-VEGF (100 μg/kg), a matching concentration of unconjugated VEGF (18.65 μg/kg), ELP alone (100 μg/kg), or placebo. Analysis of organ distribution showed high renal binding of ELP-VEGF 4 hours after stenotic kidney infusion. Therapeutic efficacy was determined 4 weeks after infusion. ELP-VEGF therapy improved renal protein expression attenuated in RVD, restoring expression levels of VEGF, VEGF receptor Flk-1, and downstream angiogenic mediators, including phosphorylated Akt and angiopoietin-1 and -2. This effect was accompanied by restored MV density, attenuated fibrogenic activity, and improvements in RBF and GFR greater than those observed with placebo, ELP alone, or unconjugated VEGF. In summary, we demonstrated the feasibility of a novel therapy to curtail renal injury. Recovery of the stenotic kidney in RVD after ELP-VEGF therapy may be driven by restoration of renal angiogenic signaling and attenuated fibrogenic activity, which ameliorates MV rarefaction and improves renal function.
PROFIL PEMBELAJARAN SAINS BERBASIS KELASS SEBAGAI UPAYA MENGEMBANGKAN KPS DAN MENINGKATKAN PKS SISWA (STUDI KASUS DI SMPN 1 KOTA JAMBI)
Authors: Sukarno Sukarno
Published: November 2015

Kegiatan Belajar Mengajar (KBM) sains di tingkat SMP bertujuan untuk mengembangkan Keterampilan Proses Sains (KPS) dan menanamkan Penguasaan Konsep Sains (PKS). Oleh karena itu, KBM sains harus memberikan peluang untuk mengembangkan KPS dan PKS secara bersama-sama dan tidak terpisahkan. KBM sains berbasis Kegiatan Eksplorasi Lingkungan Alam di Sekitar Sekolah (KELASS) dianggap mampu memberikan ruang yang luas untuk mengembangkan KPS siswa dan PKS. Oleh karena itu, penelitian kualitatif ini dilakukan dengan tujuan untuk mengetahui apa saja faktor pendukung dan faktor penghambat pelaksanaan KBM sains berbasis KELASS dan implikasinya terhadap KPS dan PKS siswa. Data hasil wawancara, observasi dan tes menunjukkan bahwa faktor pendukung KBM sains berbasis KELASS adalah sarana dan prasarana (indoor dan outdoor) yang memadai. Sedangkan kendala utama bagi para guru sains adalah tidak adanya bahan ajar sains yang berorientasi pada eksplorasi lingkungan alam sekitar sekolah untuk mengembangkan mahasiswa KPS dan PKS. Oleh karena itu, perlu dikembangkan bahan ajar sains yang dapat mempermudah guru sains dalam melakukan KBM sains berbasis KELASS.  Kata kunci:    eksplorasi lingkungan alam di sekitar sekolah, keterampilan proses sains, penguasaan konsep sains
Caminata al azar predictiva de la dinámica de obesidad y predicciones de obesidad y sobrepeso en la población infantil de Colombia y de variación peso/talla y peso/edad en México

La obesidad y el sobrepeso constituyen problemas de salud pública tanto a nivel mundial como en América Latina. La teoría de la probabilidad y la caminata al azar probabilista han sido base para el desarrollo de predicciones de la dinámica de diferentes epidemias. En este trabajo se estudió el crecimiento de la obesidad en cuatro países con base en la caminata al azar, para confirmar la capacidad de la metodología para describir y predecir esta dinámica específica, y se desarrollaron simulaciones de variables asociadasal estudio de sobrepeso y obesidad en Colombia y México, proyectando una predicción al 2015. Se estudiaron tasas de obesidad de Estados Unidos, Finlandia, Australia e Inglaterra desde 1982 a 1996, en analogía con una caminata al azar probabilista, valuando su capacidad predictiva para el año 1997. Posteriormente se desarrollaron simulaciones de la dinámica de sobrepeso y obesidad en Colombia con base en reportes reales de los años 2005 y 2010 de acuerdo con el índice de masa corporal (IMC), así como simulaciones de la dinámica de peso/talla y peso/edad en la población mexicana de menores de 0 a 5 años, dividida en cuatro regiones, con base en los reportes de 1999 y 2006, proyectándolas hasta el 2015, con base en la caminata al azar.El análisis de la dinámica de crecimiento de la obesidad con base en la caminata al azar, permitepredecir cuando los índices van a permanecer estables o cuando van a subir en Estados Unidos, Finlandia, Australia e Inglaterra, logrando predicciones con un porcentaje de efectividad igual osuperior al 97,85% para 1997. Las simulaciones obtenidas para México y Colombia predicen un comportamiento probable hasta el 2015, encontrando que en 2015 en Colombia las prevalencias de obesidad para niños de 0 a 9 años oscilarán entre 4,2 y 11,2, y de sobrepeso para niños entre 10 y 17 años entre 12,9 y 19,4. También se encontraron valores predictivos entre 0,1 y 7,7 para el 2015 en México en niños de 0 a 5 años, respecto a la variable de peso/talla, mientras que respecto a peso/edad se encontraron entre 0,2 y 11,89. Se evidenció que la metodología utilizada es útil para el estudio de diferentes variables asociadas a la dinámica de obesidad y sobrepeso y sirve como base para el desarrollo de predicciones de utilidad en la toma de decisiones de salud pública.
Un caso de aplicación de la dermatología integral
Authors: Castro Luis Antonio , Bedolla Angela María
Published: November 2015

La sarcoidosis es una enfermedad granulomatosa multisistémica de etiología desconocida. Presentamos el caso de una mujer que consulta por la preocupación estética de una lesión en dorso nasal. La exploración clínica lleva a sospechar de una enfermedad granulomatosa, por lo cual se lleva a biopsia y confirmación de su patología. La sarcoidosis es un trastorno crónico, que afecta múltiples órganos, su incidencia es variable, pero es mayor en países industrializados y se presenta en su mayoría en mujeres entre 20 y 40 años de edad. De las manifestaciones sistémicas, la más frecuente es la pulmonar, mientras que la afectación cutánea oscila entre 20-35%. El diagnóstico se establece con los hallazgos clínico-radiológicos apoyados por la evidencia histopatológica de granulomas no caseificantes, aunque estos últimos no son específicos, por lo que deben excluirse otros procesos.
Endotelina-1: vasoconstrictor intrínseco del endotelio vascular
Authors: Flores Valdez Neil
Published: November 2015

La endotelina es un péptido vasoconstrictor aislado inicialmente del cerdo de donde procede su denominación. Es considerado como el más potente vasoconstrictor conocido por el hombre, es incluso 10 veces más potente que la angiotensina II. Existen tres isoformas y están distribuidas en diversas células y tejidos interviniendo en la modulación del tono vascular, proliferación celular, producción hormonal, balance del sodio y como neurotransmisor. Para la regulación del tono vascular debe de haber un equilibrio de fuerzas vasoconstrictoras y vasodilatadoras generados por el endotelio o que ejercen influencia sobre el mismo, existen varios candidatos en la categoría de los vasoconstrictores, pero el más importante es la endotelina-1 por su potencia y su localización, ya que su acción es ejercida sobre el músculo liso vascular.

Estenosis laringotraqueal revisión de casos en el Centro Médico Imbanaco de Cali
Authors: Reyes Solarte Antonio José
Published: November 2015

El manejo de la estenosis laringotraqueal continúa siendo un problema difícil para el otorrinolaringólogo por la multiplicidad de hallazgos en los pacientes, su manejo complejo y la falta de un tratamiento único. En el Centro Médico Imbanaco de Cali, Colombia, se realizó un análisis retrospectivo de una serie de pacientes con este diagnóstico tratados entre octubre de 2006 y enero de 2011. Se examinaron los antecedentes, síntomas y signos, tratamientos, enfermedades asociadas, resultados del tratamiento y seguimiento en el tiempo. Se identificaronun total de 44 adultos, con edad promedio de 41,4 años; 24 (55%) eran mujeres y 20 hombres. El promedio de seguimiento fue 19 meses; 28 (63,6%) pacientes mejoraron con el empleo de tratamiento endoscópico y láser de CO2. Los mejores resultados se obtuvieron en el Grupo I (100%) y en el Grupo II (83.3%). La cirugía endoscópica láser,es un tratamiento válido para lesiones delgadas, no complicadas. El uso de técnicas de resección y reconstrucción laringotraqueal es útil en las lesiones complejas y gruesas donde falla el tratamiento endoscópico. No obstante, en casos seleccionados, el tratamiento endoscópico se debe considerar inicialmente. Otras ventajas del tratamiento endoscópico son; pocas complicaciones, baja morbilidad, tiempo quirúrgico y de hospitalización cortos.
