Thermoelastic vibration and maneuver control of smart satellites
Authors: Fazelzadeh S. Ahmad , Azadi Emad
Published: March 2017

Purpose

The purpose of this paper is to analyze and control the thermally induced vibration of orbiting smart satellite panels, which have been modeled as functionally graded material (FGM) beams.

Design/methodology/approach

It is assumed that the satellite moves in a circular orbit and has pitch angle rotation maneuver. Rapid temperature changes at day–night transitions in orbit generate time dependent bending moments that induce vibrations in the appendages. So, the heat radiation effects on the appendages should be considered. The thermally induced vibrations of the appendages and the nonlinear heat transfer equation are coupled and should be solved simultaneously. So, the governing equations of the motion are nonlinear and very complicated ones. A robust passivity-based controller is proposed to control the satellite maneuver and appendages vibrations, using piezoelectric sensors/actuators.

Findings

After the simulation, the effects of the heat radiation, piezoelectric actuators and piezoelectric locations on the response of the system are studied. The results of dynamic response and thermal analysis show that the radiation thermal effects are coupled with structure dynamic. These effects induce the vibration. Also, the effectiveness and the capability of the controller are analyzed. The results of the simulation show that the robust passivity-based control can ensure that the satellite rotates in the desired trajectory and vibrations of the appendages are damped. It demonstrates that the proposed control scheme is feasible and effective.

Originality/value

The paper is the basis of deriving the governing equations, thermal analysis and a robust control system design of a smart satellite with FGM panels.
Unpacking Young Migrants’ Collective Identities: The Case of Ethnonational Identifications and Belonging
Authors: Katartzi Eugenia
Published: March 2017

Based on a qualitative study of youth identities in Greece, the paper unpacks the dynamic processes of ethnonational (dis)identification and belonging that Albanian young migrants are implicated in. Analysis of in‐depth interviews illustrates how racism, coupled with their lack of citizenship, affects their (dis)identifications. Additionally, categorisation is reported to crucially mediate their belonging, giving rise to a double‐edged sense of otherness and alienation. The paper concludes by putting forward a conceptualisation of young migrants’ collective identities as involving the emotive dialectic of (dis)identification, categorisation and belonging, along with negotiation of boundaries and acceptance by ‘others’ in both home and settlement societies.
‘You Can't Have Well‐being If You're Dead…or Can You?’ Children's Realistic and Logical Approach to Discussing Life, Death and Wellbeing
Authors: Gillett‐Swan Jenna K.
Published: March 2017

Well‐being is a popularised and regularly considered aspect of an individual's life. Whilst frequently theorised across disciplines interested in childhood, children's perspectives on well‐being are often missing. This article presents children's views on well‐being, focussing on the extent they consider well‐being to exist after death or near‐death experiences. Through focus‐group discussion, children's conversations reflect their ability for deep philosophical, abstract thinking and contributing to clearer understandings of well‐being across different contexts. Children's pragmatic responses about death when considering well‐being provide a valuable contribution to understanding fear of death whilst arguing for collaborative approaches between adults and children when considering complex issues.

Authors: Inoue Ayami , Kondoh Eiji , Suginami Koh , Io Shingo , Chigusa Yoshitsugu , Konishi Ikuo
Published: March 2017

Aim

The aim of this study was to elucidate the feasibility and safety of vaginal delivery (VD) when placental abruption causes fetal demise.

Methods

We conducted a retrospective study of women who were managed for placental abruption with intrauterine fetal death at Kyoto University Hospital during the period from 1995 to 2015.

Results

Sixteen cases were identified during the study period. VD was attempted in 15 cases and was accomplished in 14 (93.3%) cases. The median gestational age was 36 (24–39) weeks, and there were eight primiparas. The median Bishop score on admission was 2.5 (1–9). Eight pregnancies were complicated with pregnancy‐induced hypertension. The median duration of labor was 5 h and 18 min (30 min–12 h 43 min), and the median amount of hemorrhage was 2503 (445–6808) mL. Fresh frozen plasma (≥ 20 U) and red cell concentrate (≥ 10 U) were administered in 10 (71%) and 9 (64%) cases, respectively. Two cases required uterine artery embolization for post‐partum hemorrhage, while there was no case of maternal death or hysterectomy. Patients with Bishop score > 3 (n = 6) experienced shorter‐duration deliveries (P = 0.020) and had significantly larger blood loss volume (P = 0.020) compared to patients with Bishop score ≤ 3. The duration of labor was negatively correlated with the amount of blood loss (R2 = −0.56, P = 0.039).

Conclusion

After placental abruption with intrauterine fetal death, VD is feasible and safe regardless of gestational age, parity, cervical maturity, and duration of labor when intensive medical resources are available.
The company you keep: Qualitative uncertainty in providing a club good
Authors: Datta Bipasa , Fraser Clive D.
Published: March 2017

Clubs are typically experience goods. Potential members cannot ascertain precisely beforehand their quality (dependent endogenously on the club's facility investment and number of users, itself dependent on its prices). Members with unsatisfactory initial experiences discontinue visits. We show that a monopoly profit maximizer never offers a free trial period for such goods. For quality functions homogeneous of degree of at least minus one, a welfare maximizer, motivated by distributional concerns to mitigate disappointed consumers' losses, always does. We demonstrate the robustness of this finding by showing that (i) without qualitative uncertainty (thus, no disappointed customers), neither welfarist nor monopolist offers free trials; and (ii) if the planner pursues an objective mixing welfare maximization with profit maximization, the likelihood of free trials increases with the weight put on welfare maximization. Regarding club quality and usage, the monopolist provides a socially excessive level of quality to repeat buyers when the quality function is homogeneous of degree zero. With nonhomogeneous quality functions, the monopolist permits too little club usage; quality may or may not be socially excessive.
Violence, Atonement, and Retributive Justice: Bonhoeffer as a Test Case
Authors: Burkholder Benjamin
Published: March 2017

Recent soteriological discourse has worried that atonement theologies like satisfaction and penal substitution have potentially damaging effects like inoculating us to our violence, further buttressing retributive justice, and inducing passive acquiescence in the face of abuse. Though legitimate concerns in their own right, this essay investigates whether certain views on the atonement do in fact produce the issues of concern. By investigating the thought of Dietrich Bonhoeffer, who believed that God had to punish sin, this article will seek to identify the complex nuances in Bonhoeffer's work that would potentially safeguard against some of the concerns being raised about atonement theologies like his.
How do functional traits syndromes covary with growth and reproductive performance in a water‐stressed population of Fagus sylvatica?
Authors: Bontemps Aurore , Davi Hendrik , Lefèvre François , Rozenberg Philippe , Oddou‐Muratorio Sylvie
Published: March 2017

A central issue in plant evolutionary ecology is to understand how several coordinated suites of traits (i.e. traits syndrome) may be jointly selected within a single species. This study aims to describe patterns of variation and co‐variation of functional traits in a water‐stressed tree population and test their relationships with performance traits.

Within a Mediterranean population of Fagus sylvatica experiencing recurrent summer droughts, we investigated the phenotypic variation of leaf unfolding phenology, leaf area (LA), leaf mass per area (LMA), leaf water content (LWC), water use efficiency (WUE) estimated by carbon isotopic discrimination (d13C), twig Huber‐value (HV: the stem cross‐section divided by the leaf area distal to the stem), wood density (WDens), and leaf nitrogen content (Nmass).

First, a principal component analysis revealed that two main axes structured the phenotypic variability: the first axis opposed leaf unfolding earliness and LWC to LMA and WUE; the second axis opposed LA to HV. These two axes can be interpreted as the opposition of two strategies (water economy versus water uptake) at two distinct scales (leaf for the first axis and branches for the second axis). Second, we found that LMA, LA, leaf unfolding and LWC responded differently to competition intensity, while WUE, WDens and HV did not correlate with competition. Third, we found that all studied functional traits were related to growth and/or reproductive performance traits and that these relationships were frequently non‐linear, showing strong interactions between traits.

By highlighting phenotypic clustering of functional traits involved in response to water stress and by evidencing antagonistic selection favouring intermediate trait values as well as trait combinations, our study brought new insights on how natural selection operates on plant functional traits in a stressful environment.
ERP evidence for conflict in contingency learning
Authors: Whitehead Peter S. , Brewer Gene A. , Blais Chris
Published: March 2017

The proportion congruency effect refers to the observation that the magnitude of the Stroop effect increases as the proportion of congruent trials in a block increases. Contemporary work shows that proportion effects can be driven by both context and individual items, and are referred to as context‐specific proportion congruency (CSPC) and item‐specific proportion congruency (ISPC) effects, respectively. The conflict‐modulated Hebbian learning account posits that these effects manifest from the same mechanism, while the parallel episodic processing model posits that the ISPC can occur by simple associative learning. Our prior work showed that the neural correlates of the CSPC is an N2 over frontocentral electrode sites approximately 300 ms after stimulus onset that predicts behavioral performance. There is strong consensus in the field that this N2 signal is associated with conflict detection in the medial frontal cortex. The experiment reported here assesses whether the same qualitative electrophysiological pattern of results holds for the ISPC. We find that the spatial topography of the N2 is similar but slightly delayed with a peak onset of approximately 300 ms after stimulus onset. We argue that this provides strong evidence that a single common mechanism—conflict‐modulated Hebbian learning—drives both the ISPC and CSPC.
Food and Drug Administration's Humanitarian Device Exemption Marketing Approval Pathway: Insights for Developing Devices for Rare Diseases
Authors: Liu Gumei , Chen Eric , Lewis Debra , Rao Gayatri
Published: March 2017

The Food and Drug Administration's (FDA) Humanitarian Device Exemption (HDE) is a unique marketing approval pathway for medical devices targeting diseases affecting small (rare) patient populations. In an effort to increase the utilization and success of this pathway, the FDA has analyzed data from HDE approvals from 2007 to 2015 to identify factors that have contributed to a successful HDE marketing application. There were 28 HDE approvals during the analysis period and were based on a broad range of data constituting valid scientific evidence. Most had at least one prospectively conducted clinical trial to support safety and probable benefit. An analysis of these HDE approvals demonstrates that the FDA exercises a high degree of flexibility when reviewing HDE applications.
Size-Dependent Elasticity of Nanoporous Materials Predicted by Surface Energy Density-Based Theory
Authors: Yao Yin , Yang Yazheng , Chen Shaohua
Published: March 2017

The size effect of nanoporous materials is generally believed to be caused by the large ratio of surface area to volume, so that it is also called surface effect. Based on a recently developed elastic theory, in which the surface effect of nanomaterials is characterized by the surface energy density, combined with two micromechanical models of composite materials, the surface effect of nanoporous materials is investigated. Closed-form solutions of both the effective bulk modulus and the effective shear one of nanoporous materials are achieved, which are related to the surface energy density of corresponding bulk materials and the surface relaxation parameter of nanomaterials, rather than the surface elastic constants in previous theories. An important finding is that the enhancement of mechanical properties of nanoporous materials mainly results from the compressive strain induced by nanovoid's surface relaxation. With a fixed volume fraction of nanovoids, the smaller the void size, the harder the nanoporous material will be. The results in this paper should give some insights for the design of nanodevices with advanced porous materials or structures.
Polarization effects in light-by-light scattering: Euler–Heisenberg versus Born–Infeld
Authors: Rebhan Anton , Turk Günther
Published: March 2017

The angular dependence of the differential cross-section of unpolarized light-by-light scattering summed over final polarizations is the same in any low-energy effective theory of quantum electrodynamics and also in Born–Infeld electrodynamics. In this paper, we derive general expressions for polarization-dependent low-energy scattering amplitudes, including a hypothetical parity-violating situation. These are evaluated for quantum electrodynamics with charged scalar or spinor particles, which give strikingly different polarization effects. Ordinary quantum electrodynamics is found to exhibit rather intricate polarization patterns for linear polarizations, whereas supersymmetric quantum electrodynamics and Born–Infeld electrodynamics give particularly simple forms.
Maximal T-spaces of free associative algebras over a finite field
Authors: Bekh-Ochir C. , Rankin S. A.
Published: March 2017

In earlier work, it was established that for any finite field [Formula: see text] and any nonempty set [Formula: see text], the free associative (nonunitary) [Formula: see text]-algebra on [Formula: see text], denoted by [Formula: see text], had infinitely many maximal [Formula: see text]-spaces, but exactly two maximal [Formula: see text]-ideals (each of which was shown to be a maximal [Formula: see text]-space). This raises the interesting question as to whether or not the maximal [Formula: see text]-spaces can be classified. However, aside from the two maximal [Formula: see text]-ideals, no examples of maximal [Formula: see text]-spaces of [Formula: see text] have been identified to this point. This paper presents, for each finite field [Formula: see text], an infinite set of proper [Formula: see text]-spaces [Formula: see text] of [Formula: see text], none of which is a [Formula: see text]-ideal. It is proven that for any distinct integers [Formula: see text], [Formula: see text]. Furthermore, it is proven that for the prime field [Formula: see text], [Formula: see text] any prime, [Formula: see text] is a maximal [Formula: see text]-space of [Formula: see text]. We conjecture that for any finite field [Formula: see text] of positive characteristic different from 2 and each integer [Formula: see text], [Formula: see text] is a maximal [Formula: see text]-space of [Formula: see text]. In characteristic 2, the situation is slightly different and we provide different candidates for maximal [Formula: see text]-spaces.
Technical communication practices in the collaborative mediascape
Authors: Löwgren Jonas
Published: March 2017

Professional practices in technical communication are increasingly being challenged by the emergence of collaborative media that enable users to access technical information created by non-professionals. At the same time, these technologies also allow technical communicators to provide a continually expanding audience with knowledge and skills needed now more than ever. Through a co-design case study, researchers developed a new and innovative platform for producing and distributing technical information including user-generated content. Moreover, the events of the case included market strategies in which a professional organization moved from a reactive to a more proactive position on collaborative media. In so doing, they outlined a set of new professional roles for technical communicators including editors, curators, facilitators, and community managers.

Effects of Cognitive Effort on the Resolution of Overspecified Descriptions
Authors: Paraboni Ivandré , Lan Alex Gwo Jen , de Sant'Ana Matheus Mendes , Coutinho Flávio Luiz
Published: March 2017

Studies in referring expression generation (REG) have shown different effects of referential overspecification on the resolution of certain descriptions. To further investigate effects of this kind, this article reports two eye-tracking experiments that measure the time required to recognize target objects based on different kinds of information. Results suggest that referential overspecification may be either helpful or detrimental to identification depending on the kind of information that is actually overspecified, an insight that may be useful for the design of more informed hearer-oriented REG algorithms.
Error cascade in taxonomy: The case of Cardiomya perrostrata (Mollusca: Bivalvia: Cuspidariidae) in Brazilian waters
Authors: OLIVEIRA CLÉO D. C. , SARTORI ANDRÉ F. , ABSALÃO RICARDO S.
Published: March 2017

Successions of erroneous taxonomic identifications in biodiversity studies are an undesirable but not rare phenomenon. Such cascades of errors frequently involve taxa with few, polymorphic diagnostic characters, such as representatives of the cuspidariid genus Cardiomya. Four species of the genus are believed to live in Brazilian waters: C. cleryana (d’Orbigny, 1842), C. ornatissima (d’Orbigny, 1853), C. striata (Jeffreys, 1876) and C. perrostrata (Dall, 1881). Many reported occurrences of these species are based on misidentifications, but the error cascade of incorrect records of C. perrostrata is by far the most extensive. Although the species has been reported to live in Brazilian waters for about half a century, all previous records seem to be based on a succession of mistaken identifications. This paper redescribes C. perrostrata based on an analysis of the type series, several lots of museum vouchers and new material collected in the Campos Basis (Rio de Janeiro, Brazil). Ontogenetic changes in shell outline and ultrastructural details of the hinge plate, periostracal surface and larval shell are described and illustrated for the first time. Based on a critical appraisal of the literature, we present an updated geographic and bathymetric distribution of the species. Cardiomya perrostrata displays a gradual increase in the relative length of the rostrum during its ontogeny and in larger specimens the rostrum is more prominently curved upwards. The larval shell is of type 2D, measuring about 215–235 μm in length. The periostracum is minutely pitted and a lithodesma is present. Its distribution is Western Atlantic, ranging from 42°N to 30°S, in depths of 18 to 1646–1829 m. Cardiomya knudseni (Allen & Morgan, 1981), a possibly related amphi-Atlantic species whose type material has been lost, is regarded herein as a nomen dubium.

Optical Emission Lines and the X-Ray Properties of Type 1 Seyfert Galaxies
Authors: La Mura G. , Ciroi S. , Cracco V. , Ilić D. , Popović L. Č. , Rafanelli P.
Published: March 2017

In this contribution we report on the study of the optical emission lines and X-ray spectra of a sample of Type 1 AGNs, collected from the SDSS database and observed by the XMM-Newton satellite. Using different instruments onboard XMM, we identify the spectral components of the soft and hard energy bands (in the range from 0.3 keV to 10 keV). The properties of the X-ray continuum and of the Fe Kα line feature are related to the optical broad emission line profiles and intensity ratios. The resulting picture of emission, absorption and reflection processes is interpreted by means of a structural model of the broad line region, developed on the basis of independent optical and radio observations.

Published: March 2017

Most of the Broad Absorption Lines (BALs) in quasars show very complex profiles. An idea to explain these profiles is that the dynamical systems of broad line regions are not homogeneous but consist of a number of dense regions or ion populations with different physical parameters. This approach is used to study the ultraviolet CIV resonance lines in the spectra of a group of high ionization BAL quasars, using the Gauss-Rotation model.

We present preliminary results of the long-term spectral monitoring of two active galactic nuclei with different broad line shapes: Ark 564 and Arp 102B. Ark 564 is a bright nearby narrow-line Syfert 1 (NLS1) galaxy with relatively narrow permitted optical emission lines and a high Fe II/Hβ ratio, while Arp 102B is a nearby broad-line radio galaxy with broad double-peaked Balmer emission lines. The spectra of Ark 564 were observed during 11-year period (1999-2009) and the spectra of Arp 102B in the 12-year period (1998-2009), with SAO 6 m and 1 m telescopes (Russia) and the OAGH 2.1 m telescope (Cananea, Mexico).

We report the preliminary results of a kinematical study of three Seyfert galaxies selected from a sample of nearby active galactic nuclei observed using 3D spectroscopy. The observations were performed at the prime focus of the 6 m telescope of SAO RAS with the integral-field spectrograph MPFS and with a scanning Fabry-Pérot interferometer, installed on the multimode device SCORPIO. Based on these data, the monochromatic maps and velocity fields in different emission lines were constructed. We have detected the nuclear outflow or ionized gas motions associated with a radio jet in all the circumnuclear regions of these galaxies.

A project for astrometric and photometric observations of asteroids at Mt. Graham Observatory with the VATT telescope is described. One of the most important results is a discovery of the Centaur 2012 DS85. Astrometric and photometric data on the asteroid are presented. The orbit of the asteroid was computed from 67 observations. Combined with its apparent brightness, the orbit gives an absolute magnitude of 9.43. Using a typical albedo value of 0.08 for Centaurs and TNOs (Moullet et al. 2011), we get a diameter of 2012 DS85 at about 61 km.
Die Odysseeparaphrase des Demosthenes Thrax
Authors: Nünlist René
Published: March 2017

Eustathius’ commentaries on Homer preserve the fragments of a paraphrase that a certain Demosthenes Thrax made of the Odyssey. This article provides a new edition of these fragments with commentary. Compared to the old edition by Gehrmann (1890), this edition produces an improved text and expands that collection by five new fragments and a new attestation of a known fragment. In addition to the usual goals of a running commentary, the present one attempts, in particular, to reconstruct the character and general principles of Demosthenes’ paraphrase, which is likely to have covered the entire Odyssey. Based on these findings, the article ends by giving a summary sketch of this remarkable work and its shadowy author.
Hydrodynamic limits of kinetic equations for polyatomic and reactive gases
Authors: Bisi M. , Spiga G.
Published: March 2017

Starting from a kinetic BGK-model for a rarefied polyatomic gas, based on a molecular structure of discrete internal energy levels, an asymptotic Chapman-Enskog procedure is developed in the asymptotic continuum limit in order to derive consistent fluid-dynamic equations for macroscopic fields at Navier-Stokes level. In this way, the model allows to treat the gas as a mixture of mono-atomic species. Explicit expressions are given not only for dynamical pressure, but also for shear stress, diffusion velocities, and heat flux. The analysis is shown to deal properly also with a mixture of reactive gases, endowed for simplicity with translational degrees of freedom only, in which frame analogous results can be achieved.

A comprehensive work was carried out to investigate natural radionuclides of 238U, 232Th and 40K in 73 soil samples collected from islands of Adır, Çarpanak and Akdamar on the Van Lake (Turkey) located at Eastern Turkey. Radioactivity concentrations of these radionuclides were measured by using a gamma spectrometer with NaI(Tl) detector to be from 4.11 to 77.1 Bq/kg, from 6.0 to 70.0 Bq/kg and from 133.05 to 749.77 Bq/kg with the mean values of 33.33 Bq/kg, 36.68 Bq/kg and 478.19 Bq/kg, respectively. In addition, the absorbed gamma dose rate in air (D) and annual effective dose equivalent (AED) were found to be 57.5 nGy/h and 70.5 μSv/year, respectively. We have shown that our results might be related to the geological formation type. The results were compared with some published ones in Turkey and the World, which were found within acceptable limits.
Local cluster networks and the number of valence states in aluminium–transition metal face-centred icosahedral quasicrystals
Authors: Kitahara Koichi , Kimura Kaoru
Published: March 2017

Coordination environments of a special class of clusters which are related to the valence states in aluminium–transition metal face-centred icosahedral quasicrystals were analysed on the basis of the six-dimensional model of Katz and Gratias for the atomic sites and that of Yamamoto for the centres of the clusters. The number of the clusters per atom in the model (≈0.263) is comparable with that of Al–Cu–Ir cubic approximant crystal (≈0.258), and it indicates that the model reasonably represents the distribution of the clusters. We identified all the possible local cluster networks of short distances, which are related to the inter-cluster bonds, and evaluated the number of the valence states by assuming two possible configurations of inter-cluster bonds. The number of the valence states per atom was derived as a function of the fraction of transition-metal atoms, and the value is in good agreement with that expected from the compositions of real quasicrystals. Notably, the number of the part of the valence states which do not depend on the fraction of transition-metal atoms is numerically similar to the electron to atom ratio known as e/a, which is phenomenologically related to the stability of quasicrystals.

The Suzuki-Miyaura reaction of 2,6-dichloro-3-(trifluoromethyl)pyridine with 1 equiv of arylboronic acids resulted in site-selective formation of 2-aryl-6-chloro-3-(trifluoromethyl)pyridine. Due to electronic reasons, the reaction takes place at the sterically more hindered position. The selectivity was rationalised by DFT calculations. The one-pot reaction with two different arylboronic acids afforded 2,6-diaryl-3-(trifluoromethyl)pyridine containing two different aryl substituents. The reactions proceeded smoothly in the absence of phosphine ligands. In addition, Suzuki-Miyaura reactions of 2,6-dichloro-4-(trifluoromethyl)pyridine with one or two equivalents of arylboronic acids were carried out.

Para tanto, este estudo está organizado da seguinte forma: Primeiro aborda-se a definição de recepção e na seqüência, discute-se os processos de implicação emotiva, priorizando as implicações do mesmo, dado que estes mecanismos são com muita frequência utilizados pela televisão e demais meios de comunicação. Interessa-nos também a apresentação de uma reflexão sobre o fenômeno zapping como técnica modificadora de condutas e acerca das respostas emotivas, como característica inerente à natureza humana.
Pasolini. Das modulações das formas fílmicas.
Authors: Bezerra Furtado Sylvia Beatriz
Published: March 2017

Este artigo é um diálogo com alguns dos escritos de Pasolini sobre cinema, em especial com as transcrições de gravações de conversas realizadas em diferentesmomentos de filmagens em La Voz de Pasolini, publicado no ano 2000, em Madrid, e nos textos, de 1957-1974, reunidos em livro pela Cahiers du Cinema, nos escritos sobre o cinema, quando Pasolini fala dos embates na construção de planos, com a inserção da luz em determinadas cenas e na forma de dirigir atores. Trata-se de entender como as formas fílmicas respondem a demandas do realizador que faz um cinema de modulações da matéria do mundo, trabalhadas em enquadramentos breves, em ápices dramáticos, em formulações dos gestos na montagem e em movimentos de câmera precisos com o objetivo de inscrever uma forma no embate com as sobreexposições das luzes sobre os corpos.
“Where does the Indian begin and where does it end?”: Legal-Criminal Categories in Peru, 1920s-1940s, and two Bolivian Cases from the 1940s*
Authors: David Lior Ben
Published: March 2017

Como tratar os Índios? Durante a primeira metade do Século 20, com a ascensão do indigenismo e sob a influência das ideias positivistas, esta antiga questão colonial reapareceu na América Latina no campo da legislação criminal. Uma grande parte do debate sobre o status legal dos criminosos indígenas girava em torno de quem exatamente seria o Índio que mereceria ou precisaria de um tratamento penal especial. Esta questão será examinada aqui, principalmente no contexto do Peru, onde o Código Penal de 1924 introduziu novas categorias legais de criminosos Indígenas, e também em duas propostas legislativas Bolivianas que procuraram adaptar a legislação criminal à “realidade Indígena” do seu país. As maneiras como estas categorias criminais foram interpretadas pelas cortes Peruanas, e reformuladas por diversas propostas legislativas Peruanas e Bolivianas, redesenharam as fronteiras interiores destas nações, e implicitamente redefiniram o termo “índio” em si mesmo. No contexto Peruano, elas também refletiram as mudanças do Indigenismo durante os anos 1920/1940.
El arte conceptual como recurso educativo, a través de las obras de algunos artistas centroamericanos
Authors: Flores Canet Alberto
Published: March 2017

Se aborda el papel del arte en la sociedad y en particular en la educación, se aportan ideas sobre el valor del arte conceptual en algunas de sus variantes expresivas, así como las posibilidades de ser utilizado como recurso didáctico en la enseñanza de algunos cursos en los cuales se pretende -además- abrir una posibilidad de explorar las tendenciasartísticas postmodernas a partir de las propuestas estéticas y vincularlas con la historia.Se toma como ejemplo la obra de cuatro artistas, cuyos trabajos son dignos de analizar desde varios ángulos, ante sobre todo por ser confrontativos, contestatarios, por la profundidad de sus contenidos y su actualidad, los cuales pueden servir de punto de partida para incorporar en la educación o cuando menos en algunos procesos de enseñanza y de aprendizaje, ya que sus obras explican situaciones de los tiempos actuales, como pueden ser: la marginalidad, la pobreza, la discriminación, la género, la ambiente, la corrupción, entre otros.

Authors: Kitt Candice , Wang Vanessa , Harvey-Fitzgerald Linda , Kayes Nicola , Saywell Nicola
Published: March 2017

This study explored the perspectives on participation in group rehabilitation in the inpatient setting for people with moderate to severe stroke. A qualitative descriptive study using in-depth semi-structured interviews ascertained the experiences and impressions of participating in a group exercise programme. Six participants were interviewed, and analysis of the data identified four main themes: Loss of self; I can’t do it alone; Being part of the whole; and, Therapeutic approach in the context of personhood. These themes allowed identification of key components that may inform development of group exercise for people with moderate to severe stroke. People with moderate to severe stroke expressed feelings of loss of who they had been. Some were reluctant to join group exercise; the need to be part of a group was sometimes overwhelmed by doubt that they could participate in a meaningful way. Those who overcame their reluctance to join found a benefit in shared experience and mutual assistance to progress. The way they were treated and the degree their autonomy was respected by physiotherapists had a significant impact on their willingness to exercise and their enjoyment of group sessions. These findings will assist the development of a group programme to increase opportunities for activity in the inpatient stroke rehabilitation setting.

In the late 90-ies of XX century in Russia there was an exacerbation of the epidemic situation of tuberculosis (TB) and “explosive” increase in pathogen drug resistances. Regardless of lower incidence of pulmonary TB in recent years, the number of cases caused by multidrug-resistant (MDR) mycobacteria was increasing due to a reduction in the effectiveness of treatment. Among the 11 subjects of the North-West Federal District the Leningrad Region is leading in the number of ineffective chemotherapy outcomes in newly diagnosed bacteriologically confirmed TB cases. A specific feature of the current epidemic situation in the Leningrad Region is the prevalence (74.1% in 2014) of MDR strains among previously treated patients with pulmonary TB. The aim of the research was a comparative genotypic characterization of Mycobacterium tuberculosis strains, isolated from patients with chronic pulmonary tuberculosis in the Leningrad Region in 1999–2004 and 2010–2014. As defined by spoligotyping, the Beijing family genotype was prevailing among M. tuberculosis strains of previously treated patients from Leningrad region (76.5% in 2010–2014 versus 56.3% in 1999–2004). The proportion of other genotypes strains — LAM and T decreased from 16.7 and 12.5% to 10.3 and 2.9%, respectively. The proportion of multi-drug resistance in the studied subpopulations of the Beijing genotype strains remained virtually constant (86.5 and 88.9%). The extensive drug resistance was not observed among MDR Beijing strains in 1999–2004, whereas in 2010–2014 it reached 33.3%. MIRU-VNTR-typing (12 loci) of 68 M. tuberculosis strains revealed 20 profiles; of these, five were presented by clusters MIT1, MIT46, MIT16, MIT17, MIT571, comprising two or more strains. The largest clusters MIT16 (223325153533) and MIT17 (223325173533) included 25 (48.1%) and 21 (40.4%) apparently highly transmissible Beijing genotype strains. Previously, clinical significance and mainly epidemic pathways for MDR M. tuberculosis Beijing strains belonging to these MIRU-VNTR-types were proved in a number of Russian regions. These findings require in-depth analysis of the situation in the region studied.

Published: March 2017

Introdução: No exercício da Odontologia, o cirurgião-dentista está sujeito a ser responsabilizado por suas ações ou omissões que resultem em danos aos seus pacientes. Essa responsabilização pode ocorrer na esfera ética, civil e penal, entre outras. Ao longo dos anos, a sociedade e a relação profissional-paciente têm se modificado apoiadas nas legislações vigentes, assim como na disseminação da informação e da comunicação. Desse modo, tem se visto um crescente número de litígios envolvendo cirurgiões-dentistas e pacientes, o que revela a importância dos profissionais conhecerem as normas que regulamentam o exercício da Odontologia, bem como, as consequências do ato ilícito. Objetivos: O presente trabalho teve como objetivos fornecer conhecimento, por meio de uma revisão de literatura, sobre o aspecto legal da responsabilidade profissional do cirurgião-dentista e destacar a importância da documentação odontológica como meio de prova da atuação profissional. Métodos: Foram utilizados livros, teses e artigos científicos publicados em bases eletrônicas como SciELO, Bireme, MedLine e Lilacs, no idioma Português, além de leis e normativas publicadas em endereços eletônicos oficias. Conclusões: Concluiu-se que um prontuário adequado resguarda o profissional; assim como uma documentação falha, compromete todo o trabalho realizado e pode resultar em uma condenação.

Background: The purpose of this study was to investigate the relationship between the genetic mutations, which are frequently detected and known to cause familial Mediterranean fever (FMF) disease, with ABO blood groups.Methods: There were 271 patients with FMF diagnosis and 271 healthy control subject enrolled in the study. The medical files of each case were screened retrospectively and demographic characteristics, genetic mutations, and ABO blood groups were recorded.Results: No statistically significant difference was detected between the two groups with respect to their gender and age (p>0/05). When patient and healthy control groups were compared based on ABO blood groups, the study groups were observed to differ significantly with respect to B blood group (p=0.008). In the patient group, a considerable relationship could not have been found when the gene mutations were compared based on blood groups, either for E148Q (n=64) and M694V (n=142) genes (p>0.05). However, a considerable difference was observed for V726A (n=58) gene; B blood group was more frequently observed among those who were detected to have V726A mutation (p=0.022).Conclusions: In present study cohort, blood type B was more frequent among FMF patients. We observed that there could be a significant association between V726A mutation and ABO blood groups.

Background: Pterygium is a fibrovascular wing or triangular shaped tissue that develops from the conjunctiva and encroaches on to the cornea.Methods: This prospective observational study was conducted at postgraduate department of Ophthalmology of GMC Jammu, Jammu and Kashmir, India. A total of 90 pterygium patients were selected to analyze various sociodemographic factors especially age, sex, residence, occupation, position etc. on the occurrence of this problem.Results: In the present study, out of 90 pterygium patients, 40% were in the age of 31-40 years followed by 24.44% in 41-50years, 60% were males whereas 66.67% belong to rural areas. The incidence was found to be maximum among farmers 35.56% followed by labourers 20%. The right eye was involved in 55.56% cases while majority 97.78% cases of pterygium were nasal. Progressive pterygium was found in 80% while 20% reported with atrophic pterygium.Conclusions: People who work outdoors are subjected to involuntary U.V. B exposure, dust. Workers must be aware of this and they must take appropriate precautions like wearing protective photochromatic glasses, caps etc.
