Published: October 2016

This article is focuses on an educational programme to facilitate critical thinking within the nursing perspective. For the purpose of developing an educational programme; the study was conducted in four phases, beginning with a needs assessment in Phase 1 through which the researcher determined the need of student nurses in terms of critical thinking. The deductive data analysis of phase 1 served as conceptual framework for the development of education programme in phase 2.Phase 2 consisted of the development of educational framework to facilitate critical thinking in student nurses. Specific educational approaches and a philosophical framework were employed during the development of the programme. An expert opinion on the programme was obtained before the implementation could be concluded in phase 3. Phase 3 and 3 of the study were conducted simultaneously. Phase 3 covered the implementation of the educational programme and Phase 4 the evaluation.The process itself includes, the purpose of the development of the programme, conducting a situational analysis; utilization of philosophical approaches, developing the educational programme; content of the programme; educational and curriculum approaches integrated into the development of an educational programme and strategies to overcome obstacles during the implementation of an educational programme.

Working toward a synthesis
Authors: Langacker Ronald W.
Published: October 2016

Although Cognitive Linguistics represents a recontextualization with respect to prior tradition, internally it has been diverse and grounded from the outset. In design and principle, this holds for Cognitive Grammar, which seeks a comprehensive yet unified account of structure and use. It foreshadowed the “social turn” by claiming that the speaker-hearer interaction is inherent in linguistic units, which are abstracted from usage events; and also the “quantitative turn”, by its usage-based nature and the view that structure resides in processing activity. There is no single way of describing a language, just as there is no single way of describing a biological organism. Linguistics is thus a vast, multifaceted enterprise embracing a wide range of objectives, methods, and expertise. A number of points are made in this regard. (i) While corpus analysis is essential for many purposes, elicited and introspective data also have their place. (ii) With no inconsistency, language is validly characterized as both a cognitive/mental phenomenon and a social/interactive one. (iii) The fact that language resides in processing activity does not entail the absence of discreteness or the non-existence of complex structures. (iv) The importance of quantitative methods does not obviate the central role of structural analysis and description, which have equal claim to being empirical.
The sociolinguistics of gender, social status and masculinity in Aristophanes
Authors: McDonald Katherine
Published: October 2016

This article explores variation in the language of male characters in the plays of the Athenian playwright Aristophanes, usingThesmophoriazusaeandFrogsas in-depth case studies. Studies of modern languages have shown that men’s linguistic practices can be just as marked for gender as women’s, and the data from these plays bears this out. Using past work on ‘female speech’ as a starting point, this article explores the incidence of gendered markers in male characters’ speech, and shows that some of these features characterise not just gender but the intersection of different aspects of identity including gender, social class and sexuality. These features include particular oaths, obscenities, certain uses of the particlege, hedging and politeness strategies. The article shows that a lack of male-associated speech markers is enough to characterise a male Greek speaker as ‘unmanly’, without the addition of female-associated speech markers.
Progression from impaired glucose tolerance to type 2 diabetes in obese children and adolescents: a 3–6-year cohort study in southern Thailand
Authors: Jaruratanasirikul Somchit , Thammaratchuchai Sudarat , Puwanant Maneerat , Mo-suwan Ladda , Sriplung Hutcha
Published: October 2016

Background:

Childhood obesity is associated with abnormal glucose metabolism and type 2 diabetes mellitus (T2DM). This study evaluated the prevalence of abnormal glucose metabolism in asymptomatic obese children and adolescents, and determined the percentage of T2DM development after 3–6 years of follow-up.

Methods:

During 2007–2013, 177 obese children and adolescents who had normal fasting plasma glucose (FPG<100 mg/dL) were given an oral glucose tolerance test (OGTT). The participants were classified into four groups: normal glucose tolerance (NGT), NGT-hyperinsulinemia (NGT-HI), impaired glucose tolerance (IGT), and diabetes mellitus (DM). Blood chemistries, including FPG, glycated hemoglobin, and lipid profiles, and liver function test were performed every 6–12 months or when the patient developed any symptom or sign indicative of diabetes.

Results:

Glucose metabolism alterations were detected in 81.4% of the participants: 63.8% with NGT-HI, 15.3% with IGT, and 2.3% with T2DM. The median levels of homeostasis model assessment-insulin resistance (HOMA-IR) in patients with IGT (8.63) were significantly greater than those in the patients with NGT (4.04) (p<0.01). During the follow-up, 22 patients (14.4%) developed T2DM significantly more from the IGT group (nine of 33 cases, 27.3%) than the NGT-HI group (12 of 108 cases, 11.1%) (p=0.022). The predicting parameters for T2DM conversion were weight status, body mass index (BMI), FBG, fasting insulin, alanine transaminase (ALT) levels, and HOMA-IR.

Conclusions:

Glucose metabolism alteration was commonly found among obese adolescents. Factors associated with T2DM development were greater weight status and the severity of insulin resistance as shown by higher HOMA-IR levels.
Association between the triglyceride to high-density lipoprotein cholesterol ratio and insulin resistance in Korean adolescents: a nationwide population-based study
Authors: Park Jae-Min , Lee Jee-Yon , Dong Jae June , Lee Duk-Chul , Lee Yong-Jae
Published: October 2016

Background:

Studies have suggested the triglyceride to high-density lipoprotein cholesterol ratio (TG/HDL-C) as a surrogate marker of insulin resistance. However, few studies have examined the association between TG/HDL-C and insulin resistance in the general adolescent population. This study aimed to examine the association between TG/HDL-C and insulin resistance in a nationally representative sample of Korean adolescents.

Methods:

A total of 2649 participants aged 12–18 years were selected from the 2007 to 2010 Korean National Health and Nutrition Examination Survey (KNHANES). Insulin resistance was defined as the homeostatic model assessment of insulin resistance (HOMA-IR) values greater than the 80th percentile.

Results:

The mean values of most cardiometabolic variables increased proportionally with TG/HDL-C quartiles. Compared to individuals in the lowest TG/HDL-C quartile, the odds ratio for insulin resistance for individuals in the highest quartile was 2.91 in boys and 2.38 in girls after adjusting for confounding variables.

Conclusions:

This study suggests that TG/HDL-C could be a convenient marker for identifying Korean adolescents with insulin resistance.
Contextualising Translator Training: Defining Social, Professional and Disciplinary Requirements
Authors: Plaza-Lara Cristina
Published: October 2016

In order to adapt universities to the social, disciplinary and professional needs, we consider it necessary to contextualise the professional profiles of translators. The main groups involved in the educational process are translation teachers and researchers, employers and students/graduates, and their contribution to the definition of professional profiles is essential. Therefore, in this article we will focus on studies about professional profiles from the following perspectives: translation market studies, academic research, research on labour market insertion and students’ expectations. These studies will allow us to draw conclusions that could be applied during curricular design.
„Arbeitssprachen: Englisch – Russisch – Deutsch. Spezialgebiet: Holocaust“: ökonomische Faktoren bei der Übersetzung von Audio-/Videointerviews mit Überlebenden des nationalsozialistischen Terrors
Authors: Degen Sylvia
Published: October 2016

This article is based on the preliminary results of an interview project with managers, project leaders, and translators from three major German multimedia archives who are/were involved with translating audio-visual Holocaust testimony for educational purposes. It will focus on the economic aspects in this highly sensitive field of translation and assess what status translation is given within these projects. Despite of the narrow research framework, the findings point out to broader issues related to current outsourcing practices instead of integrating translation as central part of a project.
The Future of Studying Hobbyist Metal Detecting in Europe: A Call for a Transnational Approach
Authors: Thomas Suzie
Published: October 2016

Much research on hobbyist metal detecting has either focused on the archaeological impact only,
conflated hobbyism with criminal activity (namely looting and illicit trade), or generalized the motivations
and drivers for metal detectorists. Studies to date have targeted specific countries and regions, with only
limited reference to metal detecting activities elsewhere. This has meant that the transnational aspects of
metal detecting – such as the international trade of metal-detected objects, and transnational movement of
metal detectorists themselves (for example through touristic activities) – has mostly been overlooked or merely
speculated upon. Much debate has revolved around assumptions, stymied by perceived ethical barriers and
accepted attitudes which limit deeper engagement with the metal detecting community. Approaching the
study of hobbyist metal detecting at a trans-European level would encourage greater understanding of the
scale of hobbyist metal detecting and the world views, activities and contact and trade networks of metal
detectorists. This may challenge traditionally-held perspectives concerning what should be valued as cultural
heritage and who is entitled to make use of it. In this paper I set out our current state of knowledge, and
propose directions for future research.

Published: October 2016

In this paper, based on Jumarie’s modified Riemann-Liouville derivative, we apply the fractional variational iteration method using He’s polynomials to obtain solitary and compacton solutions of fractional KdV-like equations. The results show that the proposed method provides a very effective and reliable tool for solving fractional KdV-like equations, and the method can also be extended to many other fractional partial differential equations.

Third phase formation in the extraction of Th(NO3)4 by Tri-sec-butyl phosphate: a comparison with Tri-n-butyl phosphate
Authors: Chandrasekar Aditi , Suresh A. , Sivaraman N.
Published: October 2016

Earlier studies carried out in our laboratory indicated that Tri-sec-butyl phosphate (TsBP) is a potential extractant for U/Th separation. Also, the third phase formation tendency of TsBP is lower compared to its isomers, Tri-n-butyl-phosphate (TBP) and Tri-iso-butyl phosphate (TiBP). In this context, the extraction and third phase formation behaviour of 1.1 M solutions of TiBP and TsBP in n-dodecane in the extraction of Th(IV) from 1 M HNO3 at 303 K over a wide range of Th concentrations were investigated in the present study and the results are compared with the literature data on TBP system. Concentrations of Th(IV) and HNO3 loaded in the organic phase before third phase formation (biphasic region) as well as in third phase and diluent-rich phase after third phase formation (triphasic region) were measured as a function of equilibrium aqueous phase Th(IV) concentration. The density of loaded organic phase was also measured at various Th(IV) concentrations. The extraction profiles in the biphasic region indicated that extraction of Th(IV) by TBP is higher than that of TiBP which in turn is higher than that of TsBP. Extractant concentration in the diluent-rich phase and third phase was measured for the triphasic region.

Published: October 2016

Environmental tobacco smoke (ETS) is one of the greatest and the most frequent environmental toxic exposures presenting a high risk to children and to their mothers as well. The aim of the study was to find determinants of the household ETS in the sample of pregnant women living in the household with smokers and to assess their physical and mental health. The survey was distributed to women being seen for follow-up at the obstetric/gynecology departments in hospitals and at gynecological out-patient departments in Bratislava, Slovakia. The medical outcomes short form-12 (SF-12) was included to quantify the mental and physical health of mothers. From the total sample of 617 women, 35.5% (219) were pregnant, 88.6% of them (194) non-smokers, 27.8% (54) lived with a smoking partner, the average mental component summary (MCS) score was 50.8±9.1 and physical component summary (PCS) score was 41.6±10.3. The average age was 31.3±5.1 years. In the sample of 309 non-pregnant non-smoking mothers 23% (71) lived with a smoking partner; the average age was 31.7±4.8 years. The average PCS score was 47.8±8.7 and MCS score 49.1±9. Non-smoking, pregnant women living with a smoker have fewer years of education (p=0.0003) and lower MCS scores (48.50±9.8) (p=0.03). Non-smoking, non-pregnant women living with a smoker are older (p=0.0042), with lower income (p=0.0145), have fewer years of education (p=0.002) and lower PCS score (45±9.1) (p=0.0056). Multivariate analyses revealed the decrease of MCS score in pregnant women and the decrease of PCS score in non-pregnant women living with a smoker. Our results show that living with a smoker is independently associated with worse physical and mental health in a selected sample of Slovak women, which represents an important argument for intervention in families.
Mit Kindern eine Sprache für das Geheimnis suchen

Behandlungen in der Pädiatrie sind auf einer spirituellen Ebene davon beeinflusst, „was es bedeutet, ein Kind zu sein“ und in welcher Beziehung die Behandler zu dem kranken oder verletzen Kind stehen. Spiritual Care in der Pädiatrie darf sich nicht darauf beschränken, die Spezifizität der behandelten Kinder zu berücksichtigen. Der Beitrag zeigt, dass die spirituellen Erfahrungen von Kindern in impliziter oder expliziter Weise durch die zwischen Eltern und Gesundheitsberufen geteilte Sorge um die Gesundheit der Kinder geprägt wird.
Gilbert’s syndrome: protective effect on endothelial dysfunction
Authors: Sertoğlu Erdim , Tapan Serkan , Doğru Teoman , Acar Ramazan , Doğan Tolga , İnce Selami , Bilgi Cumhur
Published: October 2016

Objective

Gilbert’s syndrome (GS), is a benign condition characterized by unconjugated hyperbilirubinemia related to a decreased hepatic glucuronidating activity without symptoms and signs of liver disease or overt hemolysis. In the present study, we aimed to assess circulating levels of asymmetric dimethylarginine (ADMA), pentraxin-3 (PTX-3) and high sensitivity C-reactive protein (hs-CRP) between patients with GS and controls and determine the correlation of unconjugated bilirubin (UCB) levels with these molecules as prognostic factors for vascular risk stratification and endothelial dysfunction.

Methods

Forty two patients with GS and 37 age and sex matched control subjects were enrolled in this study. The diagnosis of GS was made by unconjugated hyperbilirubinemia (1 mg/dL or >17.1 μmol/L) on at least two occasions with normal values of other liver function tests, normal hepatic imaging, and absence of hemolysis.

Results

Serum ADMA, PTX-3 and hs-CRP levels were significantly lower in GS than the healthy controls (p=0.037, p=0.025 and p=0.040, respectively). In correlation analysis, UCB was negatively correlated with ADMA, PTX-3 and hs-CRP (r=−0.239, p=0.034; r=−0.280, p=0.012 and r=−0.224, p=0.047, respectively).

Discussion and conclusion

The present study showed for the first time that decreased levels of ADMA, PTX-3 and hs-CRP may prove the protective effects of hyperbilirubinemia on the endothelial dysfunction.

Linear and Nonlinear Electrical Models of Neurons for Hopfield Neural Network
Authors: Sarwar Farah , Iqbal Shaukat , Hussain Muhammad Waqar
Published: October 2016

A novel electrical model of neuron is proposed in this presentation. The suggested neural network model has linear/nonlinear input-output characteristics. This new deterministic model has joint biological properties in excellent agreement with the earlier deterministic neuron model of Hopfield and Tank and to the stochastic neuron model of McCulloch and Pitts. It is an accurate portrayal of differential equation presented by Hopfield and Tank to mimic neurons. Operational amplifiers, resistances, capacitor, and diodes are used to design this system. The presented biological model of neurons remains to be advantageous for simulations. Impulse response is studied and conferred to certify the stability and strength of this innovative model. A simple illustration is mapped to demonstrate the exactness of the intended system. Precisely mapped illustration exhibits 100 % accurate results.
Multi-Scale Morphological Analysis of Conductance Signals in Vertical Upward Gas–Liquid Two-Phase Flow

Published: October 2016

The multi-scale analysis is an important method for detecting nonlinear systems. In this study, we carry out experiments and measure the fluctuation signals from a rotating electric field conductance sensor with eight electrodes. We first use a recurrence plot to recognise flow patterns in vertical upward gas–liquid two-phase pipe flow from measured signals. Then we apply a multi-scale morphological analysis based on the first-order difference scatter plot to investigate the signals captured from the vertical upward gas–liquid two-phase flow loop test. We find that the invariant scaling exponent extracted from the multi-scale first-order difference scatter plot with the bisector of the second-fourth quadrant as the reference line is sensitive to the inhomogeneous distribution characteristics of the flow structure, and the variation trend of the exponent is helpful to understand the process of breakup and coalescence of the gas phase. In addition, we explore the dynamic mechanism influencing the inhomogeneous distribution of the gas phase in terms of adaptive optimal kernel time–frequency representation. The research indicates that the system energy is a factor influencing the distribution of the gas phase and the multi-scale morphological analysis based on the first-order difference scatter plot is an effective method for indicating the inhomogeneous distribution of the gas phase in gas–liquid two-phase flow.

Authors: Bräuchle Sebastian , Hejny Clivia , Huppertz Hubert
Published: October 2016

BaSr2Ge3O9 was prepared by high-temperature solid-state synthesis at 1100°C in a platinum crucible from barium carbonate, strontium carbonate, and germanium(IV) oxide. The compound crystallizes in the triclinic space group P1̅ (no. 2) isotypically to walstromite BaCa2Si3O9. The structure was refined from single-crystal X-ray diffraction data: a=7.104(5), b=10.060(7), c=7.099(5) Å, α=83.0(2), β=77.0(2), γ=70.2(2)°, V=464.3(6) Å3, R1=0.0230, and wR2=0.0602 for all data. BaSr2Ge3O9 is characterized by three-membered rings of germanate tetrahedra. There are three crystallographically different Ge sites (Ge1, Ge2, and Ge3) in each [Ge3O9]6− ring. The rings occur in layers with the apices of alternating rings pointing in opposite directions. The Sr2+ and Ba2+ ions are located in between. The Sr1 cation is eight-fold coordinated, while Sr2 is octahedrally surrounded by oxide anions, and the Ba cation again eight-fold coordinated.
Anodic Voltammetric Behavior of Lincomycin and its Electroanalytical Determination in Pharmaceutical Dosage form and Urine at Gold Electrode
Authors: Abbar Jyothi C. , Meti Manjunath D. , Nandibewoor Sharanappa T.
Published: October 2016

The anodic voltammetric behavior of an antibiotic drug, lincomycin hydrochloride (LIN) at gold electrode (GE) has been investigated using cyclic and linear sweep voltammetry. The dependence of the current on pH, concentration and scan rate were investigated to optimize the experimental conditions for the determination of lincomycin. The anodic peak was characterized and the process was adsorption-controlled. The number of electrons transferred in the oxidation process was calculated. In the range of 8.0×10−6to 1.0×10−4M, the current measured by linear sweep voltammetry presents a good linear property as a function of the concentration of lincomycin with a detection limit of 1.7×10−7M with good selectivity and sensitivity. The proposed method was successfully applied to lincomycin determination in pharmaceutical dosage form and in urine as a real sample. This method can be employed in clinical analysis, quality control and routine determination of drugs in pharmaceutical formulations.
"O aparelho é como um automóvel; a pista é a paciente": para além do ensino de tecnologia no pré-natal
Authors: Chazan Lilian Krakowski
Published: October 2016

O presente estudo contempla as práticas e ideias envolvidas na formação acadêmica de um grupo social relevante: o dos médicos que, dada sua posição hierárquica significativa na produção da marca ultrassom obstétrico, parece-nos ser um ponto de "parada" interessante e fundamental no fluxo circular entre ideias, marcas e coisas que constituem esse objeto, ultrassom. A observação etnográfica da situação de ensino permite captar dinamicamente esse momento fundamental no qual os principiantes são apresentados a uma tecnologia que foi histórica (e provisoriamente) constituída como indispensável no acompanhamento pré-natal. Pretende-se, assim, apreender de que modo é produzida a "socialização visual" dos futuros profissionais; a pesquisa empírica evidenciou que, juntamente com um determinado tipo de olhar, outros elementos bastante heterogêneos também são ensinados aos futuros médicos. Uma tensão bastante presente no campo consiste na dicotomia entre uma abordagem eminentemente clínica e outra, de teor fortemente tecnicista. A eventual precariedade de dispositivos tecnológicos evidencia diversos paradoxos e incongruências nesta segunda tendência. As modificações ocorridas no desenrolar dos diversos processos que se articulam no campo observado são discutidas em termos do que são capazes de revelar sobre os grupos sociais envolvidos em sua produção.
Oxalobacter formigenes–Derived Bioactive Factors Stimulate Oxalate Transport by Intestinal Epithelial Cells

Published: October 2016

Hyperoxaluria is a major risk factor for kidney stones and has no specific therapy, although Oxalobacter formigenes colonization is associated with reduced stone risk. O. formigenes interacts with colonic epithelium and induces colonic oxalate secretion, thereby reducing urinary oxalate excretion, via an unknown secretagogue. The difficulties in sustaining O. formigenes colonization underscore the need to identify the derived factors inducing colonic oxalate secretion. We therefore evaluated the effects of O. formigenes culture conditioned medium (CM) on apical 14C-oxalate uptake by human intestinal Caco-2-BBE cells. Compared with control medium, O. formigenes CM significantly stimulated oxalate uptake (>2.4-fold), whereas CM from Lactobacillus acidophilus did not. Treating the O. formigenes CM with heat or pepsin completely abolished this bioactivity, and selective ultrafiltration of the CM revealed that the O. formigenes–derived factors have molecular masses of 10–30 kDa. Treatment with the protein kinase A inhibitor H89 or the anion exchange inhibitor 4,4'-diisothiocyano-2,2'-stilbenedisulfonic acid completely blocked the CM-induced oxalate transport. Knockdown of the oxalate transporter SLC26A6 also significantly restricted the induction of oxalate transport by CM. In a mouse model of primary hyperoxaluria type 1, rectal administration of O. formigenes CM significantly reduced (>32.5%) urinary oxalate excretion and stimulated (>42%) distal colonic oxalate secretion. We conclude that O. formigenes–derived bioactive factors stimulate oxalate transport in intestinal cells through mechanisms including PKA activation. The reduction in urinary oxalate excretion in hyperoxaluric mice treated with O. formigenes CM reflects the in vivo retention of biologic activity and the therapeutic potential of these factors.
Option-Implied Libor Rate Expectations across Currencies
Authors: Gebbia Nick
Published: October 2016

In this paper, I study risk-neutral probability densities regarding future Libor rates denominated in British pounds, euros, and US dollars as implied by option prices. I apply Breeden and Litzenberger’s (1978) result regarding the relationship between option prices and implied probabilities for the underlying to estimate full probability density functions for future Libor rates. I use these estimates in case studies, detailing the evolution of probabalistic expectations for future Libor rates over the course of several important market events. Next, I compute distributional moments from density functions estimated for fixed horizons and test for Granger causality across the three Libor rate distributions considering their mean, standard deviation, skewness, and kurtosis. I further break these relationships down by various fixed horizon lengths, as well as the slope and curvature in the term structure of moments over different horizons. The results show a rich interconnectedness among these three Libor rates that extends well beyond levels of future mean expectations.
Pedagogical habitus engagement: teacher learning and adaptation in a professional learning community
Authors: Feldman Jennifer
Published: October 2016

Situated within the context of teaching in post apartheid South Africa, this article discusses the establishment and functioning of a professional learning community (PLC) that was constituted to generate pedagogical learning and adaptation among practicing teachers in consonance with a socially just teaching orientation. Drawing on the thinking tools of Bourdieu, the article offers a view of PLCs as a form of "habitus engagement" that engages with teachers' firmly established pedagogical identities, their "pedagogical habitus," to effect adaptation and change in their classroom pedagogy. The exemplifying basis of this article is empirical data drawn from a 2-year PLC process where teachers from different school contexts collaborated to find ways to conceptually and pragmatically shift and change their pedagogy. The article highlights both the limits and possibilities of teachers' pedagogical change and concludes by arguing that the ongoing, reflexive, and dialogical PLC process, as a form of habitus engagement, holds the potential to challenge, adapt, and shift teachers' pedagogical habitus to conceptually and pragmatically include a more socially just teaching orientation in their classroom pedagogy.
Cuando la intimidad es política. Arte y homosexualidad en el Centro Cultural Ricardo Rojas de Buenos Aires durante los años ’90.
Authors: Rosa María Laura
Published: October 2016

Las propuestas que tuvieron como cita la galería de arte del Centro Cultural Ricardo Rojas, dependiente de la Universidad de Buenos Aires, apuntaron a estéticas locales emergentes muchas de las cuales comenzaban a hablar temas silenciadosen el país como la cuestión gay. Sus exposiciones, talleres, debates y publicaciones marcaron la escena undergroundlocal. Sin embargo a partir de 1992/93 se tornará en un espacio consagrado y de referencia para el campo oficial de la crítica y el coleccionismo. En el presente artículo me propongo una lectura política de algunas obras de los artistas Feliciano Centurión (San Ignacio de las Misiones, Paraguay, 1962 –Buenos Aires, 1996) y Marcelo Pombo (Buenos Aires, 1959). Tomo como herramienta de análisis la teoría de arte feminista y su entendimiento de que lo personal es político. Planteo, así, una lectura que busca ir más allá de lo formulado por la historiografía tradicional, abriendo el debate sobre cuestiones referidas a la identidad y la homosexualidad.

O objetivo deste artigo é discutir o adultocentrismo presente em nossas relações cotidianas junto às crianças. Nele mostraremos que nosso entendimento acerca das crianças e das infâncias construiu-se com base numa concepção adulta idealizada, fortalecida ao longo da história humana, a qual enxerga a criança quase que somente como ser em desenvolvimento, portanto, não ainda completo. Refletiremos também como o mundo adulto deu materialidade a uma determinada noção hegemônica de infância, aquela decorrente do latim, indicando suas consequências à vida das crianças. Por fim, defenderemos a quebra do modelo hegemônico de nossas relações adultocentradas frentes às crianças.

(Non-)Monumental Layers of Berlin
Authors: Székely Juli
Published: October 2016

The two books reviewed in this article, Hsiu-Ling Kuos’s Monumentality and Modernity in Hitler’s Berlin (2013) and Janet Ward’s Post-Wall Berlin (2011), focus on the structural, political, social and aesthetic transformation of Berlin, from the first half of the twentieth century to the ‘post-wall’ era. Since both authors strongly emphasize the former and present status of monumental architecture and monumental memory, this book review pays particular attention to a critical discussion of the (non-)monumental layers of Berlin.
Transculturalism and Translation
Authors: Giffard Hermione
Published: October 2016

Transculturalism is an approach to studying cultures that pays particular attention to how cultures interact. Because it aspires to be a new way of studying cultural intermingling, transculturalism is still searching for concepts and vocabulary to define a unique approach to history. In their advice for aspiring transculturalists, the three books examined here stress the usefulness of the metaphor of translation for viewing how cultures interact. A product of and a response to increased interest in the global, the empirical case studies in these books open a new view of the construction of global imaginaries and how we might more usefully study them, but seem to add little to existing approaches to intercultural interaction.

The behavior of a slight chiral bias in favor of l-amino acids over d-amino acids was studied in an evolutionary mathematical model generating mixed chiral peptide hexamers. The simulations aimed to reproduce a very generalized prebiotic scenario involving a specified couple of amino acid enantiomers and a possible asymmetric amplification through autocatalytic peptide self-replication while forming small multimers of a defined length. Our simplified model allowed the observation of a small ascending but not conclusive tendency in the l-amino acid over the d-amino acid profile for the resulting mixed chiral hexamers in computer simulations of 100 peptide generations. This simulation was carried out by changing the chiral bias from 1% to 3%, in three stages of 15, 50 and 100 generations to observe any alteration that could mean a drastic change in behavior. So far, our simulations lead to the assumption that under the exposure of very slight non-racemic conditions, a significant bias between l- and d-amino acids, as present in our biosphere, was unlikely generated under prebiotic conditions if autocatalytic peptide self-replication was the main or the only driving force of chiral auto-amplification.

Ribonuclease Dicer plays a pivotal role in RNA interference pathways by processing long double-stranded RNAs and single-stranded hairpin RNA precursors into small interfering RNAs (siRNAs) and microRNAs (miRNAs), respectively. While details of Dicer regulation by variety of proteins are being elucidated, less is known about non-protein factors; e.g. RNA molecules, that may influence the enzyme activity. Therefore, we decided to investigate the problem of whether the RNA molecules can function not only as Dicer substrates but also as its regulators.Our previous in vitro studies indicated that the activity of human Dicer can be influenced by short RNA molecules that either bind to Dicer or interact with its substrates, or both. Those studies were carried out with commercial Dicer preparations. Nevertheless, such preparations are usually not homogeneous enough to carry out more detailed RNA-binding studies. Therefore, we have established our own system for the production of human Dicer in insect cells. In this manuscript we characterize the RNA-binding and RNA-cleavage properties of the obtained preparation. We demonstrate that Dicer can efficiently bind single-stranded RNAs longer than ~20-nucleotides. Consequently, we revisit possible scenarios of Dicer regulation by single-stranded RNA species ranging from ~10- to ~60-nucleotides, in the context of their binding with the enzyme. Finally, we show that siRNA/miRNA-sized RNAs may affect miRNA production either by binding to Dicer or by regulatory feedback-loops. Altogether, our studies suggest a broad regulatory role of short RNAs in Dicer functioning.

Background: Developing a drug carrier with favorable handling characteristics that can respond to environmental changes after inflammation, such as pH changes, may be beneficial for treating periodontitis. This study aims to investigate the preclinical feasibility of using naringin, a naturally derived polymethoxylated flavonoid compound with anti‐inflammatory properties, to inhibit periodontitis induction via a thermogelling and pH‐responsive injectable hydrogel.

Methods: The hydrogel was made of amphipathic carboxymethyl‐hexanoyl chitosan (CHC), β‐glycerol phosphate (β‐GP), and glycerol. Thermogelling and pH‐responsive characteristics of the hydrogel, as well as cell viability after treatment with the hydrogel containing naringin, were evaluated in vitro. Hydrogel was subgingivally delivered when experimental periodontitis was induced in vivo, and therapeutic effect was evaluated with microcomputed tomography imaging, histology, and expression of inflammation‐associated genes, including toll‐like receptor (TLR)2, the receptor for advanced glycation end products (RAGE), myeloid differentiation primary response gene‐88, and tumor necrosis factor (TNF)‐α.

Results: The hydrogel was consistently fluidic at 4°C but rapidly gelled at 37°C. Release of naringin was faster at pH 5.5 to 6.5, and viability was significantly promoted by treatment with 0.85% naringin. Naringin‐carrying CHC‐β‐GP‐glycerol hydrogel sites showed significantly reduced periodontal bone loss (P <0.05) and inflammatory infiltration (P <0.01) as well as significantly downregulated TLR2 (P <0.05), RAGE (P <0.01), and TNF‐α (P <0.05) relative to the sites with experimental periodontitis alone.

Conclusion: Naringin‐carrying CHC‐β‐GP‐glycerol colloidal hydrogel can be used to inhibit induction of experimental periodontitis with favorable handling and inflammation‐responsive characteristics.
La Carmen de Pedro Castera
Authors: Sandoval Adriana
Published: October 2016

La novela más famosa de Pedro Cstera ha sido considerada por la mayor parte de los estudiosos de la literatura mexicana del siglo XIX como la novela romántica mexicana o como el mejor exponente de la novel sentimental mexicana. No obstante, es posible abordarla desde otros ángulos que resultan de interés en una lectura de principios del siglo XXI.
Fernando Valle: un suicida romántico, en Clemencia de Altamirano
Authors: Sandoval Adriana
Published: October 2016

El XIX es el siglo de la consolidación del individualismo, vinculado con el liberalismo; es también de los nacionalismos, fomentados en gran medida por el romanticismo, o mejor dicho, los romanticismos. Sin embargo, al mismo tiempo que promovía el nacionalismo, el romanticismo ponía un fuerte énfasis en la subjetividad. Ignacio Manuel Altamirano percibía todas estas corrientes, y es posible ver a dos de ellas en lucha -el subjetivismo y el nacionalismo- en su más célebre novela, Clemencia (1868).
Concha Urquiza: poemas de la adolescencia (inéditos y no recopilados)
Authors: León Margarita
Published: October 2016

La figura contradictoria de Concha Urquiza, su poesía de altos vuelos, más su corta trayectoria vital, sobre la que se cierne la duda de su suicidio, la hace ser polémica y legendaria. Fue mujer de notable belleza y cultura, de amena y enterada charla; mujer de letras y entrañable maestra; amiga lo mismo de estridentistas y de comunistas que de sacerdotes; militante política y postulante a monja. Observa en lo privado una conducta liberal a la vez que guarda celosamente los preceptos de la Iglesia Católica.
La anotación en textos virreinales: hacia una anotación crítica
Authors: Higashi Alejandro
Published: October 2016

Resumen: en este artículo, el autor analiza los criterios de anotación explícitos o implícitos de un número importante de ediciones críticas de textos virreinales. Proponiendo en cada caso analogías con el método de la crítica textual, discute la necesidad de explicitar criterios que rigen sobre las prácticas, para de este modo incentivar las tomas de decisiones consensuadas y reducir, en la medida de lo posible, la confusión en los criterios individuales nacida de la falta de una reflexión explícita en la disciplina respecto a las normas con que anotamos nuestros textos virreinales.Abstract: In this article, the author analyzes the criteria for explicit or implicit annotation of a significant number of critical editions of viceregal texts. Proposing in each case analogies with the method of textual criticism, the author discusses the necessity of creating explicit criteria to govern the practice, and thus incentivize the making of decisions by consensus and to reduce, as much as possible, the confusion of individual criteria born from the lack of an explicit reflection in the discipline regarding the norms with which we annotate our viceregal texts
Gringo viejo de Carlos Fuentes
Authors: Boldy Steven
Published: October 2016

De acuerdo con el autor, su interés por esta novela se centra en su estética maliciosa y ambigua; la mañosa y desorganizadora presencia de anglicismos en el español de los estadounidenses; el aire hollywoodesco de un Tortilla-Western en muchas de las escenas; el marco intelectual que es ostensiblemente antagónico; y además, por el ataque público y vehemente contra Carlos Fuentes por parte de Enrique Krauze.

Ciudad de la memoria de José Emilio Pacheco: hacia la creación de un único poemario
Authors: Olivera-Williams María Rosa
Published: October 2016

La obra de José Emilio Pacheco se mueve hacia adelante, pero siempre retomando un impulso en lo ya creado. A diferencia de sus anteriores libros de poesía, Ciudad de la memoria, no se organiza en secciones. Treinta y cinco poemas que se entretejen libremente van desarrollando los temas constantes de Pacheco: el tiempo y sus derivados, la vejez, la muerte, el olvido y su envés, la memoria, la fugacidad de todo lo creado por el hombre, contrastada con la perennidad cíclica de la naturaleza.

La vertiente romántica en la obra de Manuel Gutiérrez Nájera: su poesía
Authors: Gutiérrez José Ismael
Published: October 2016

El panorama literario del último tercio del siglo XIX en América Latina se hace más complejo por la convergencia de un naturalismo y de un realismo transculturados que se aclimatan y se desnudan de sus postulados originales, así como por la perduración de una fecunda línea costumbrista heredada de la visión crítica, retroactiva, que impuso el romanticismo, todavía hacia 1875 y en años subsiguientes en continuada, aunque declinante trayectoria.La producción literaria de Manuel Gutiérrez Nájera nace nada menos que en este periodo signado por la transición estética, por la hibridez, por la alinealidad y la dominación de varias secuencias literarias.
