Individual quality as sensitivity to cysteine availability in a melanin-based honest signalling system
Authors: Galván Ismael , Alonso-Alvarez Carlos
Published: May 2017

The evolution of honest animal communication is mostly understood through the handicap principle, which is intrinsically dependent on the concept of individual quality: low-quality individuals are prevented from producing high-quality signals because if they did so, they would pay greater production costs than high-quality individuals. We tested an alternative explanation for the black bib size of male house sparrows Passer domesticus, an honest signal of quality whose expression is negatively related to levels of the pigment pheomelanin in its contituent feathers. We previously showed that experimental depletions of cysteine, which participates in pheomelanogenesis, improve the phenotype (bibs larger than controls) of high-quality males (birds with largest bibs initially) only. Here we conducted an experiment under opposite conditions, increasing the availability of dietary cysteine, and obtained opposite results: deteriorated phenotypes (bibs smaller than controls) were only expressed by high-quality birds. Some birds were also treated with the pro-oxidant diquat dibromide, and we found that the cellular resistance to free radicals of high-quality birds benefited more from the antioxidant activity of cysteine against diquat than that of low-quality birds. These findings support the existence of a mechanism uncoupling cysteine and pheomelanin in low-quality birds that confers them a low sensitivity to variations in cysteine availability. This constitutes an explanation for the evolution of signal honesty that overcomes the limitations of the handicap principle, because it provides a specific definition of individual quality and because costs are no longer required to prevent low-quality individuals from producing large signals.

Interventions de l’herméneutique juridique dans la résolution des ambiguïtés de la loi lors des contestations en justice à l’époque byzantine
Authors: Paparriga-Artémiadi Lydia
Published: May 2017

Prenant pour point de départ une illustration succincte des principales influences de la théorie rhétorique de l’intention (voluntas) sur la promotion de l’interprétation du droit au cours de la période romaine et des premiers siècles de Byzance, l’étude s’attache à repérer des éléments des “constitutions des causes” rhétoriques dans certains textes d’un traité juridique du xiie siècle, l’Ecloga librorum Ι-Χ Basilicorum. La construction juridique de l’application analogique d’une règle de droit coutumier à une affaire précise portée devant un tribunal ainsi que l’invocation de notions axiologiques telles que le “raisonnement” (λογισμός) dans le développement de l’argumentation judiciaire et de la formulation du jugement prouvent la nature et la fonction particulières de la réflexion juridique, en tant que réflexion qui est parfois appelée à dépasser les règles de l’art oratoire.

Pengaruh Perubahan Penggunaan Lahan Sub DAS Rawapening terhadap Erosi dan Sedimentasi Danau Rawapening
Authors: Aprilliyana Dian
Published: May 2017

Konferensi Nasional Danau Indonesia  ( KNDI )  di Bali tahun 2009 menetapkan Danau Rawapening sebagai salah satu dari 15  ( lima belas )  danau/waduk yang memerlukan prioritas dalam pemulihan kerusakan danau di Indonesia. Alih fungsi lahan yang terjadi pada Sub DAS Rawapening memicu terjadinya peningkatan kerusakan lahan yang berimbas pada tingginya laju erosi dan s edimentasi di Danau Rawapening. Penelitian ini menggunakan pendekatan positivistik/kuantitatif dengan metode analisis yang digunakan adalah metode penelitian deskriptif yang menggambarkan variabel -variabel dan fenomena-fenomena yang terjadi. Hasil perhitungan erosi dan sedimentasi menunjukkan bahwa erosi dan sedimentasi di Danau Rawapening menurun dari tahun 1991, 2001 dan 2011. Hal ini dikarenakan ada beberapa faktor yang bersifat dinamis pada analisis yang dilakukan. Untuk melihat pengaruh perubahan penggunaan lahan terhadap erosi dan sedimentasi secara mendalam maka digunakan nilai erosivitas rata-rata sebesar 2.523,09. Hasil analisis menunjukkan bahwa penurunan luas lahan tegakan berbanding terbalik dengan laju erosi, jumlah erosi dan sedimentasi. Sedang kan luasan lahan terbangun berbanding lurus dengan laju erosi, jumlah erosi, dan sedimentasi. Perubahan penggunaan lahan yang menyebabkan kenaikan erosi terbesar adalah perubahan penggunaan lahan dengan tegakan menjadi lahan terbangun dan perubahan penggunaan lahan pertanian menjadi lahan terbangun.Kata kunci : perubahan penggunaan lahan, erosi, sedimentasi
Design, Synthesis and biological evaluation of diazeno-thiazole derivatives as ribonucleotide reductase inhibitors
Authors: Mohd Siddique Mohd Usman , Jadav Surender Singh , Graser Geraldine , Saiko Philipp , Szekeres Thomas , Sinha Barij N , Jayaprakash Venkatesan
Published: May 2017

Ribonucleotide reductase(RNR) is a metalloenzyme that catalyses the rate limiting step in DNA synthesis and repair. It causes the reduction of ribonucleotide to 2â€™-deoxyribonuclotides which are used as precursors for DNA synthesis, thus offering a good target for inhibition of cell synthesis. Experimental results have been proven that RNR inhibitors can be used as antiviral, anticancer or antibacterial agents. Here we report the synthesis of a novel class of diazeno-thiazole derivatives as potent RNR inhibitors. A series of forty molecules were synthesized and evaluated for their RNR inhibitory properties. All compounds were found to be good inhibitors of the RNR. Compound 3iwas found to be most active showing an IC50 value of 0.8 Âµm. The established SAR study indicated the presence of a polar bridge with an adjacent flexible aromatic ringprerequisite for RNR inhibitory activity. Moreover, compounds having an additional 4-chloro phenyl ring were found to be most potent.

Authors: Henriksen Kerm , Dymek Chris , Harrison Michael I. , Brady P. Jeffrey , Arnold Sharon B.
Published: May 2017

Background:

The Improving Diagnosis in Health Care report from the National Academies of Sciences, Engineering and Medicine (NASEM) provided an opportunity for many groups to reflect on the role they could play in taking actions to improve diagnostic safety. As part of its own process, AHRQ held a research summit in the fall of 2016, inviting members from a diverse collection of organizations, both inside and outside of Government, to share their suggestions regarding what is known about diagnosis and the challenges that need to be addressed.

Content:

The goals of the summit were to learn from the insights of participants; examine issues associated with definitions of diagnostic error and gaps in the evidence base; explore clinician and patient perspectives; gain a better understanding of data and measurement, health information technology, and organizational factors that impact the diagnostic process; and identify potential future directions for research.

Summary and outlook:

Plenary sessions focused on the state of the new diagnostic safety discipline followed by breakout sessions on the use of data and measurement, health information technology, and the role of organizational factors. The proceedings review captures many of the key challenges and areas deserving further research, revealing stimulating yet complex issues.

Introduction: the transformation of Tibet’s language ecology in the twenty-first century
Authors: Roche Gerald
Published: May 2017

Tibet’s linguistic diversity is undergoing drastic transformations in the twenty-first century. In this article, I begin my examination of this issue by outlining the extent of Tibet’s linguistic diversity, including not only its numerous Tibetic languages, but also its non-Tibetic minority languages. Using a “language ecology” approach, I examine the mechanisms that have produced and maintained this diversity, as well as the ways this diversity was spatially and socially patterned. I argue that these processes and patterns were largely maintained up until the twenty-first century, when the Chinese state’s program to “Open the West” unleashed an ideologically driven modernization program on Tibet, radically altering its language ecology. I argue that the present trends emerging from this process are likely to continue throughout the twenty-first century, resulting in both language loss and the emergence of new languages, leaving the overall language ecology fundamentally altered by the beginning of the twenty-second century. It is hoped that this article will not only provide a useful framework for future discussions on linguistic diversity in Tibet, but will also focus attention on the challenges facing individual languages in Tibet today.
GluA2-Lacking AMPA Receptors and Nitric Oxide Signaling Gate Spike-Timing–Dependent Potentiation of Glutamate Synapses in the Dorsal Raphe Nucleus
Authors: Haj-Dahmane Samir , Béïque Jean Claude , Shen Roh-Yu
Published: May 2017

The dorsal raphe nucleus (DRn) receives glutamatergic inputs from numerous brain areas that control the function of DRn serotonin (5-HT) neurons. By integrating these synaptic inputs, 5-HT neurons modulate a plethora of behaviors and physiological functions. However, it remains unknown whether the excitatory inputs onto DRn 5-HT neurons can undergo activity-dependent change of strength, as well as the mechanisms that control their plasticity. Here, we describe a novel form of spike-timing–dependent long-term potentiation (tLTP) of glutamate synapses onto rat DRn 5-HT neurons. This form of synaptic plasticity is initiated by an increase in postsynaptic intracellular calcium but is maintained by a persistent increase in the probability of glutamate release. The tLTP of glutamate synapses onto DRn 5-HT is independent of NMDA receptors but requires the activation of calcium-permeable AMPA receptors and voltage-dependent calcium channels. The presynaptic expression of the tLTP is mediated by the retrograde messenger nitric oxide (NO) and activation of cGMP/PKG pathways. Collectively, these results indicate that glutamate synapses in the DRn undergo activity-dependent synaptic plasticity gated by NO signaling and unravel a previously unsuspected role of NO in controlling synaptic function and plasticity in the DRn.
Differential Expression and Cell-Type Specificity of Perineuronal Nets in Hippocampus, Medial Entorhinal Cortex, and Visual Cortex Examined in the Rat and Mouse
Authors: Lensjø Kristian Kinden , Christensen Ane Charlotte , Tennøe Simen , Fyhn Marianne , Hafting Torkel
Published: May 2017

Perineuronal nets (PNNs) are specialized extracellular matrix (ECM) structures that condense around the soma and proximal dendrites of subpopulations of neurons. Emerging evidence suggests that they are involved in regulating brain plasticity. However, the expression of PNNs varies between and within brain areas. A lack of quantitative studies describing the distribution and cell-specificity of PNNs makes it difficult to reveal the functional roles of PNNs. In the current study, we examine the distribution of PNNs and the identity of PNN-enwrapped neurons in three brain areas with different cognitive functions: the dorsal hippocampus, medial entorhinal cortex (mEC) and primary visual cortex (V1). We compared rats and mice as knowledge from these species are often intermingled. The most abundant expression of PNNs was found in the mEC and V1, while dorsal hippocampus showed strikingly low levels of PNNs, apart from dense expression in the CA2 region. In hippocampus we also found apparent species differences in expression of PNNs. While we confirm that the PNNs enwrap parvalbumin-expressing (PV+) neurons in V1, we found that they mainly colocalize with excitatory CamKII-expressing neurons in CA2. In mEC, we demonstrate that in addition to PV+ cells, the PNNs colocalize with reelin-expressing stellate cells. We also show that the maturation of PNNs in mEC coincides with the formation of grid cell pattern, while PV+ cells, unlike in other cortical areas, are present from early postnatal development. Finally, we demonstrate considerable effects on the number of PSD-95-gephyrin puncta after enzymatic removal of PNNs.

Comportamiento humano y prevención de dengue: Estudio en barrios endémicos de Barranquilla, Bucaramanga y Armenia (Colombia)
Authors: Torres Pérez Giannina , Aguilar Rodríguez Daniel Ernesto
Published: May 2017

El presente artículo expone resultados obtenidos en la investigación sobre los predictores del comportamiento que motivan el almacenamiento de agua en barrios endémicos de las ciudades de Barranquilla, Bucaramanga y Armenia (Colombia). A través de un monitoreo de almacenamiento, suministro de agua y tipo y mantenimiento de recipientes en casas centinela, así como de la implementación de un cuestionario sobre la adaptación de hogares al suministro de agua, se determinaron los factores sociales y ambientales que intervienen en el comportamiento humano, especialmente, en lo relacionado con el almacenamiento de agua. Dentro de las principales motivaciones para dicho almacenamiento se encontraron las interrupciones periódicas del suministro de agua y la necesidad de reducción de costos del servicio. A partir de estos hallazgos se evidencia la pertinencia de desarrollar estrategias multisectoriales, que incluyan una fase de sensibilización sobre la necesidad de generar prácticas apropiadas y seguras de almacenamiento, a fin de reducir el riesgo de producción del vector del dengue al interior de los hogares.
Participación de los padres de familia en la escuela. La violencia como mediadora de la relación entre los padres y la escuela
Authors: Martínez Nieto Lina Paola
Published: May 2017

El artículo reflexiona sobre cómo los procesos de participación de los padres de familia en la escuela, expresados en las formas de relación que se establecen entre ellos, muestran isomorfismo con las dinámicas de violencia que han caracterizado histórica y culturalmente a la sociedad de nuestro contexto colombiano. El análisis se fundamenta en la legitimación de dicha violencia, como medio de interacción social, a través de dispositivos de dominación en los ámbitos del cuerpo, el lenguaje y el espacio, en los términos de Alejandro Castillejo (2009). Las ideas que se exponen en el artículo son fruto de algunos hallazgos iniciales de la investigación “Representaciones sobre la participación de los padres de familia en la escuela”, que la autora está desarrollando en el Colegio San Bernardino IED en Bogotá, pero éste no constituye un reporte de la investigación ni expone sus resultados, es un análisis de algunos aspectos identificados en el trabajo de campo que evidencian la presencia de dinámicas de violencia en el contexto de la escuela.

Selected Developments in South African Labour Legislation Related to Persons with Disabilities
Authors: Basson Yvette
Published: May 2017

In South Africa marginalised groups have historically been afforded legislative protection in order to ensure that the rights of these groups are respected, protected, promoted and fulfilled. Examples of two such groups are older persons, whose rights are provided for in terms of the Older Persons Act 13 of 2006 and children, whose rights are provided for in terms of the Children's Act 38 of 2005. Persons with disabilities have, however, not yet been the subject of dedicated legislation outlining the content of the rights to which they are entitled. As a result of this lack of dedicated legislation, the rights of persons with disabilities are dealt with in a piecemeal fashion, often in disparate pieces of legislation.

In addition to this focus on the rights of persons with disabilities, South African labour law has recently undergone extensive amendments. These amendments have led to the rights of persons with disabilities in the workplace being affected substantially. Since these amendments are as yet untested, little scrutiny of these provisions and the effect they may have on persons with disabilities has been undertaken. This article will thus discuss selected amendments of the labour legislation, and interrogate the practical effect these amendments may have on the rights of such persons. Of particular importance for the purposes of this article is the updating of an existing institution known as Sheltered Employment Factories, as well as the introduction of harsher penalties for employers who remain non-compliant with certain provisions of the Employment Equity Act 55 of 1998.
Strengthening mutual accountability and performance in agriculture in Southern Africa
Authors: Nhemachena Charles , Matchaya Greenwell , Nhlengethwa Sibusiso
Published: May 2017

We critically assessed experiences in the implementation of agricultural joint sector reviews in supporting mutual accountability in Southern Africa, focusing on the lessons learned, the challenges and recommendations for improvement. Empirical data were gathered from four countries that have implemented joint sector reviews: Malawi, Mozambique, Swaziland and Zambia. The results show that recent efforts to conduct joint sector review assessments in these countries have raised the quest for increased accountability for action and results. Despite progress to strengthen mutual accountability in the countries, monitoring and evaluation capacity remains a concern, especially at sub-national levels. The mutual accountability process and implementation of the agricultural joint sector review processes in the respective countries have come a long way in facilitating sector-wide engagement of stakeholders in planning, implementation and monitoring and evaluation of agricultural policies and programmes. These processes are critical to ensure effective implementation and realisation of development impacts of agricultural priorities in the national agricultural investment plans.

Significance: 

The implementation of the CAADP mutual accountability framework is critical to ensure effective implementation and realisation of development impacts of agricultural priorities in the national agricultural investment plans.
Agriculture joint sector reviews facilitate sector-wide engagement of stakeholders in planning, implementation, and monitoring and evaluation of agricultural policies and programmes.

Are University Libraries in Kerala Ready to Market Information Services and Products? An Investigation
Authors: Suresh Kumar P. K.
Published: May 2017

The marketing of information services is very useful to improve the image and to attract more users to the library and hence it is an important area of interest in the university library profession in recent years. This study aims to understand the existing information services and products, to study the marketing orientation based on four marketing mix variables such as product, place, price and promotion, to study the approach of librarians towards marking activities and to identify the problems encountered in marketing of information products and services of the university libraries in Kerala. The data for the study collected from the university librarian or in-charge of four university libraries in Kerala such as Kerala University Library, Mahatma Gandhi University Library, Cochin University of Science and Technology Library and CH Mohammed Koya Library of University of Calicut. All the university libraries in Kerala have some sort of conventional as well as IT enabled information services and products that can be marketed. The librarians have a positive attitude towards marketing. The identified problems encountered are lack of trained staff and less demand for the existing resources and services. It is indeed in the university libraries in Kerala to initiate new information services and products suitable for the different user groups. From the analysis of the marketing elements viz. product, place, price and promotion, it is observed that university libraries in Kerala need better promotional activities. A separate marketing division with skilled staff with a marketing plan is desirable to make the marketing activities more efficient and effective.

Published: May 2017

Paraneoplastic syndromes (PNS) refer to a phenomenon whereby certain malignancies manifest as symptoms not directly related to the tumor itself. PNS has been described in association with Hodgkin lymphoma (HL) in adults and children and may affect a number of organ systems. The pathophysiology is variable and in many cases is not well understood. Specific paraneoplastic antibodies have been isolated in some syndromes, though are not required for the diagnosis. The two best described for HL are the anti-Tr and anti-mGluR5 antibodies identified in some cases of limbic encephalitis and cerebellar degeneration respectively. A high index of suspicion for underlying malignancy is necessary when recognizing these clinical syndromes to avoid a diagnostic delay. Successful treatment of the HL often reverses the manifestations of PNS although organ function at diagnosis may limit therapeutic options. Some patients suffer devastating complications of their PNS.

Cavernous sinus syndrome (CSS) is a rare clinical entity which results in compression of the neurovascular structures in the cavernous sinus, potentially leading to headache, ophthalmoplegia, and neuropathy. The most common causes are tumor, trauma, inflammation, aneurysm, and infection. We report the case of an 82-year-old male with osseous-predominant metastatic prostate cancer who was admitted for intractable right-sided periorbital pain and diplopia. He also developed a headache with associated mild ptosis and weak cranial nerve (CN) VI function. He later developed complete right eye ptosis, complete CN VI paralysis, and palsies of CNs III and IV. Magnetic resonance imaging (MRI) of the sella turcica confirmed a distinct enhancing lesion in the cavernous sinus and he was diagnosed with CSS as a result of bony metastasis from his prostate cancer. He was started on high-dose steroids, and underwent directed radiation therapy. Bone metastasis is common with prostate cancer with predilection for more proximal structures such as the iliac bones and lumbar spine. Cases of CSS stemming from metastatic prostate cancer are rare. Thus, the development of CN palsy and ophthalmoplegia along with orbital pain should trigger a thorough investigation of the etiology of CSS which should include primary malignancies and metastasis from more distant structures such as the prostate.
La Enseñanza de las Matemáticas a través del Aprendizaje Cooperativo en 2º Curso de Educación Primaria
Authors: Iglesias Muñiz Jesús , Lopez Miranda Teresa , Fernandez-Rio Javier
Published: May 2017

El objetivo del estudio fue analizar los efectos del aprendizaje cooperativo como herramienta metodológica para la enseñanza de las matemáticas. Para ello se utilizó un diseño cuasi-experimental con grupos no equivalentes de estudiantes. Un total de 33 estudiantes pertenecientes a dos clases intactas de 2º de Educación Primaria accedieron a participar. Una experimentó un planteamiento basado en la metodología cooperativa (GE), mientras que con la otra se usó un planteamiento tradicional (GC). La valoración de los efectos de los distintos planteamientos se realizó de manera cuantitativa a través de un test de conocimientos matemáticos y de manera cualitativa a través de dibujos argumentados. Los resultados cuantitativos mostraron que el grupo-clase que trabajó cooperativamente alcanzó niveles más altos de rendimiento matemático, mientras que de los resultados cualitativos emergieron tres categorías positivas: diversión, aprender y trabajo en equipo y tres negativas solo en el GC: aburrida/cansada, difícil y mal comportamiento. El aprendizaje cooperativo parece ayudar a debilitar las percepciones negativas de los estudiantes hacia la clase de matemáticas.
Porque sí nos importa. La implicación educativa de las madres marroquíes inmigrantes en Cataluña
Authors: Alcalde Campos Rosalina
Published: May 2017

Las conductas de implicación educativa de padres y madres pueden explicar en gran medida los resultados académicos de los descendientes, según demuestran diversidad de investigaciones en el campo de la psicología y de la sociología. Esto abarca también a las familias de origen inmigrante. Desde la sociología de la educación, numerosos estudios han confirmado que las hijas e hijos de padres inmigrantes obtienen peores resultados académicos. Si bien en España los estudios que analizan en profundidad las conductas de implicación parental de estas familias como factor explicativo no son abundantes. En el caso español, sabemos que el colectivo marroquí presenta un rendimiento escolar por debajo de los estudiantes españoles pero también respecto a otros grupos de alumnos de origen inmigrante. Por ello este artículo examina hasta qué punto la implicación parental podría estar involucrada en este fenómeno. Nuestro trabajo visibiliza también el protagonismo que las mujeres madres marroquíes tienen en estos procesos, acorde a una perspectiva de género femenino. Los resultados de nuestro estudio cualitativo, con 14 madres de origen marroquí residentes en Barcelona, indican que el seguimiento escolar que realizan es considerablemente alto. Incluso en situaciones de riesgo de exclusión social y de condiciones de pobreza.

Authors: Beznyakov A. M. , Gorbulin V. I. , Kargu D L. , Fadeev A. S. , Scherbakov V. I.
Published: May 2017

The paper is devoted to the optimization of using Earth remote sensing space modules of an orbital system in the survey overview mode for vast areas. It is suggested that the controlled area should be described by a set of non-overlapping Dirichlet domains spherical polygons with equal circumradii. Each center of a Dirichlet domain (nodal point) is described at any point of time by the priority coefficient which depends on the importance of the area and the length of the time interval after the previous observation of the given point by one of the orbital system satellites. The target function in the optimization task of using Earth remote sensing space modules is the accumulative value of importance coefficients of the node points included in the plan of space modules application. An algorithm for solving the defined problem of combinatorial optimization is proposed taking into account the restrictions on power consumption and volumes of accumulated target information transferred to consumers.

Published: May 2017

Digital half-tone images (DHI) represented by g-digit binary numbers often possess great statistical redundancy which can contribute to increasing DHI reception noise immunity. The paper presents algorithms of DHI non-linear filtration based on Markovian networks with several states that make it possible to reduce the time of image transmission. The filtration algorithms are investigated in the presence of white Gaussian noise. The results of the investigation confirm the theoretical assumptions of the possibility of improving DHI reception quality without the increase in energy resources on the transmitting side of the communication channel.
