Educating in other Ways: Alternative Pedagogies and Different Schools in The Second Half of the Twentieth Century
Authors: Pintassilgo Joaquim
Published: January 2020

The monographic issue of Espacio, Tiempo y Educación presented here seeks to promote a critical reflection, based on a support of historiographic research, about the experiences of alternative pedagogies and different schools developed between the 50s and 80s of the twentieth century and with reference to the present. Particular attention is given to the various metamorphoses of the progressive tradition and to the way in which the ideas underlying these projects and movements have circulated internationally and have been creatively appropriated in various local contexts.
Ideas de los profesores de instrumento de conservatorio sobre las funciones y finalidades de la evaluación
Authors: González Royo Aránzazu , Bautista Alfredo
Published: January 2020

La mayor parte de la investigación sobre las ideas del profesorado acerca de la evaluación proviene de estudios realizados con profesores de educación general (p.ej. primaria, secundaria, universidad). En contraste, existen pocos trabajos realizados con profesores de enseñanzas artísticas, específicamente de interpretación musical en conservatorios. El objetivo de este estudio fue describir las ideas de profesores de instrumento acerca de las funciones y finalidades de la evaluación, comparándolas con las ideas propuestas en el currículo de enseñanzas musicales vigente. Los participantes fueron 18 profesores de instrumento de la Comunidad de Madrid. Se realizó una entrevista semi-estructurada en la que preguntamos a los profesores sobre las finalidades que consideraban a la hora de evaluar. Las respuestas se analizaron mediante análisis de contenido. Encontramos que las finalidades fundamentales mencionadas con más frecuencia fueron las sumativa, formativa y autoevaluación del profesor, mientras que calificar fue mayormente referida como finalidad secundaria. Pocos profesores hicieron alusión a la finalidad formadora. Asimismo, hallamos que las respuestas hacían alusión tanto a las funciones social y pedagógica de la evaluación. Concluimos que las ideas de los profesores entrevistados reflejaban sólo parcialmente lo establecido en el currículo de música vigente. Esto es especialmente notable en la poca presencia de la finalidad formativa, en comparación con la relevancia prescrita desde el currículo. Se discuten las limitaciones del estudio y se sugieren futuras líneas de investigación que contemplen las tensiones entre las funciones pedagógica y social a lo largo de cada ciclo educativo.
Las enseñanzas artísticas superiores en la ordenación educativa en España. Una visión crítica
Authors: Vieites Manuel F
Published: January 2020

A finales del siglo XX culmina en España el proceso de integración de enseñanzas superiores en la universidad. Sin embargo, las enseñanzas artísticas superiores se han mantenido fuera del espacio universitario por razones diversas, y entre las más recurrentes figura una supuesta singularidad que demandaría lo que se ha definido como ecosistema propio. Con este artículo, elaborado tras una revisión de normativa y literatura pertinente al amparo de la Historia de la Educación, analizamos las razones esgrimidas en los discursos más críticos con la opción universitaria, y consideramos supuestos avances normativos derivados de leyes recientes. Como conclusión defendemos que la integración universitaria sigue siendo la opción más adecuada al potencial de tales estudios, la más acorde con los retos que deben enfrentar y la que mejor se acomoda al bien común.
Aspectos básicos sobre el concepto y puesta en práctica de la coeducación emocional
Authors: Suberviola Iratxe
Published: January 2020

Las actuales teorías de la educación abogan por una formación centrada en la adquisición de competencias, habilidades y capacidades. Dentro de éstas se encontrarían los componentes de la Inteligencia Emocional. La importancia de indagar y hacer visibles las diferencias en las Competencias Emocionales entre hombres y mujeres es transcendental en el ámbito educativo puesto que, esto permite llevar a cabo una educación que compense las desigualdades a la que el sistema educativo y, la educación no formal, han sometido a los diferentes géneros.En el siguiente artículo se realiza una propuesta teórica sobre los aspectos didácticos básicos, matizando las diferencias entre Educación Primaria y Secundaria, que debe incorporar un programa de Coeducación Emocional. El desarrollo de los aspectos curriculares parte del análisis de los estudios sobre Inteligencia y Competencias Emocionales en los que se contempla la variable género.
Lejos de la naturaleza, la cultura se torna insostenible. Cultivar nos acerca a la naturaleza
Authors: García Carrasco Joaquin
Published: January 2020

Objetivo: Proponer y justificar una iniciativa pedagógica que fomenta el contacto directo con la naturaleza. Método: Rastrear en la bibliografía los argumentos que demuestran cómo la cultura tomó inicio en el contacto directo con el ecosistema, incluso antes de desplegarse la industria lítica y antes de que apareciera la competencia lingüística. Demostrar que el inicio del movimiento ecológico implicó la denuncia de la degradación de la biosfera y la propuesta del sentido del asombro como eje de la Educación Ambiental. Fuentes: las de carácter científico que justifiquen el objetivo serán interdisciplinares; y documentos internacionales que convergen en el mismo punto de vista. Conclusión: El huerto escolar puede ser un instrumento pedagógico, para recuperar la familiaridad con el mundo de la vida y contexto para profundizar en las tramas que nos vinculan con los demás seres vivos. La ecoalfabetización es un movimiento cultural que recomienda y valora el huerto escolar como instrumento para motivar el conocimiento y la sensibilidad para con los seres vivos.
Professores indígenas no Sul do Brasil: dos contextos de dominação/submissão aos caminhos da autonomia
Authors: Bergamaschi Maria Aparecida , Antunes Cláudia Pereira
Published: January 2020

O presente trabalho aborda especialmente a formação de professores kaingang no sul do Brasil. Sustentado metodologicamente em uma perspectiva cartográfica, o estudo visa mostrar um movimento histórico que, aos poucos, rompe com as práticas de dominação e tutela impostas aos povos originários. Inauguradas pela colonização portuguesa, práticas de dominação se estenderam e aprofundaram ao longo do período colonial e, principalmente no século XX, em que o Estado brasileiro criou mecanismos mais eficazes para a integração do indígena à sociedade nacional, entre eles a educação escolar. Embora o processo de dominação/subordinação tenha causado danos à existência autônoma de cada povo indígena, mostramos também que houve um forte, por vezes silencioso, processo de re-existência, que se torna mais evidente e retumbante nas últimas duas décadas do século XX e nos anos 2000. Registros documentais e estudos historiográficos analisados evidenciam os movimentos tímidos e pontuais do Estado, muitas vezes em consonância com ordens religiosas, na formação de professores Kaingang para as escolas criadas nas Terras Indígenas. Mudanças ocorrem a partir da Constituição Federal de 1988, abolindo oficialmente a tutela e a educação escolar integracionista e amparando legalmente as lutas indígenas por uma escola diferenciada, com professores pertencentes a seus povos. Em decorrência, observa-se uma atuação indígena protagonista e autônoma, que rompe com as práticas tutelares implementadas em contextos de dominação/submissão, criando caminhos para a autonomia no que tange à educação escolar diferenciada e à formação e atuação dos professores indígenas.
¿Descolonizar la sociología? Reflexiones a partir de una experiencia práctica
Authors: Altmann Philipp
Published: January 2020

La sociología decolonial ha sido un proyecto de un grupo considerable de pensadores. Existen muchos textos que contribuyen a una crítica de las raíces coloniales e imperiales de la sociología, de su institucionalización cuestionable, de sus inherentes estructuras de poder, o de su persistente eurocentrismo. No obstante, generalmente, estos textos dejan del lado la enseñanza de sociología, especialmente, si se da en el Sur Global. El presente texto intenta remediar eso. Parte de la experiencia concreta de la formación de una facultad de ciencias sociales como de la reforma de la malla curricular de sociología en una universidad del Sur Global. Esta experiencia y el material relacionado a ella forma la base para una reflexión teórica que busca poner en diálogo el debate decolonial con una realidad local particular. Haciendo énfasis en la importancia de lo local, este texto se desarrolla en un esquema que lleva a la formulación de tres principios para una sociología decolonial: la doble contextualización, la comparación y la autocrítica.
La descolonización epistemológica y la educación política en Colombia. Hacia una perspectiva ciudadana del buen vivir
Authors: Piedrahita Rodríguez Jarol Andrés
Published: January 2020

En este artículo, que parte de la revisión teórica realizada dentro del desarrollo de una tesis doctoral, se pretende analizar el aporte que la descolonización epistemológica puede realizar a las transformaciones necesarias en el sistema educativo colombiano, tomando como ejemplo la educación política o ciudadana. Para ello se revisan inicialmente los conceptos más importantes en la discusión epistemológica clásica, con los planteamientos de Karl Popper, Thomas Kuhn, Paul Feyerabend y la Teoría Crítica; luego se presentan los principales postulados de las teorías descoloniales y las epistemologías del sur, sus conceptos centrales, autores representativos y aportes a la discusión epistemológica; para posteriormente realizar la revisión de las experiencias y fundamentos teóricos de las corrientes pedagógicas que se inscriben en esta tendencia, abordando los principios del Buen Vivir y del Vivir Bien, desde los cuales se analiza críticamente la propuesta de educación ciudadana en Colombia. Finalmente se concluye que un proceso de descolonización epistemológica, a partir de los principios del Buen Vivir, es necesario, no solamente para la educación política, sino también para el sistema educativo en general, en la búsqueda de nuevas formas de educación, fundadas en el respeto por todas las formas de vida, respeto hacia el otro y hacia la naturaleza.
Decolonizing Knowledge. Starting Points, Consequences and Challenges
Authors: Clemens Iris
Published: January 2020

The call for the decolonization of knowledge refers to both its colonization and contingency and puts the focus on the multiplicity of knowledge. This contradicts European-North-American thinking and definitions of knowledge. Consequently, to advance an epistemological decolonization of knowledge, the actual process of defining knowledge will be analysed and the multiplicity of perspectives stressed at the epistemological level. Using Indian epistemology as an example, I will work out differences in definitions of knowledge and therefore basic diversifications in describing and explaining the emergence of knowledge. Truth-value-neutral forms of knowledge in particular challenge dominant European-North-American philosophical definitions, which incontrovertibly include assumptions of true or false knowledge. An interesting overlap between some Indian epistemologies and postcolonial theories can be observed with regards to the central role of the contextualization of knowledge production and the socially embodied nature of scientific knowledge in general. If the incentives gained are to be taken seriously, the consequences for educational science in general as well as educational practices must be discussed. According to the findings of organizational theory, emphasis on diversification and complication is also seen as an opportunity for the emergence of fresh meaning. Referring to Helen Verran’s concept of generative tension as a sign of collective creativity, encounters between diverse forms of knowledge and epistemological principles are seen as sources of creative processes and prerequisite for the emergence of new positions, perspectives etc., and thus as incubators for innovations.
Fausto Reinaga sobre educación. Un esbozo
Authors: Kölbl Carlos
Published: January 2020

El boliviano Fausto Reinaga (1906-1994) es considerado uno de los pensadores «indios» más importantes de la descolonización. Después de delinear los rasgos de una psicología de la descolonización y de hacer anotaciones breves acerca de la vida y obra de Reinaga, se analizan tres de sus escritos pertenecientes a diferentes etapas de su producción intelectual con particular atención a su concepción de la educación: Franz Tamayo y la revolución boliviana (1956), La revolución india (1970/2007) y América india y occidente (1974/2014). Las lecturas muestran diferentes aspectos del concepto de educación de Reinaga en y para Bolivia/Indoamérica como por ejemplo una crítica rigurosa a la escuela (rural) o a la alfabetización en castellano y esfuerzos de enaltecer la auto-estima «india» a partir de una relectura de la historia boliviana como «epopeya india». Se discuten estos y aspectos afines en referencia a las diferentes etapas de la obra de Reinaga y a discursos indigenistas. Aunque Reinaga es un pensador indianista que critica severamente discursos indigenistas también comparte algunas de sus ideas centrales.
Epistemological Decolonization and Education. International Perspectives
Authors: Knobloch Phillip Dylan Thomas
Published: January 2020

It is increasingly argued that European colonialism has left its mark not only in the political and economic structures of the current world system, but also in the fields of culture, science and education. Against this background, the demand for a comprehensive epistemic or epistemological decolonization is raised. This issue follows on from this demand to clarify to what extent the phenomena of cultural colonization and coloniality also affect the fields of pedagogy and educational science. In particular, the meaning of the demand for epistemic or epistemological decolonization in the field of education will be discussed. In the introduction to this volume, the main features of decolonial thinking are presented. This is a movement of critical thinking that starts from the history of Latin America in order to reconstruct, criticize and deconstruct the globally powerful connection between modernity and coloniality. After this short introduction, the individual contributions from this issue on decoloniality will be briefly presented. Finally, the differences and similarities of the individual articles are briefly referred to. In the end, the question is raised, whether decolonial education should distinguish itself more strongly within the discipline.
A study on the cinnabar-bottomed burials of the early Bronze Age
Authors: Zhang Guoshuo , He Jun
Published: January 2020

Bottoming burials with cinnabar emerged in Phase II of the Erlitou Culture of the Xia Dynasty, which might be an important step of the interment ceremony of the Xia people, especially the elites, with the meaning of laying foundations for the burials in order to bless the deceased in the afterworld. This funeral custom became more common, which might be because of the northward expansion of the Erlitou Culture into southern Shanxi that involved absorbing or replacing local cultural elements. In the early Shang Dynasty, cinnabar-bottomed burials continued to exist, which supports the traditional belief that “Shang people followed the regulations of Xia”. By the time of the late Shang Dynasty, the popularity of waist pit burials increased while the ability of the Shang people to control the cinnabar resource declined, and consequently we see fewer cinnabar-bottomed burials.

Rethinking the origins of animal domestication in China
Authors: Yuan Jing , Dong Ningning
Published: January 2020

Initial animal domestication in early Neolithic China may have resembled the behavior of raising animals as pets for entertainment. During the domestication process, the ecological characteristics and living habits of each animal and the subjective demands of ancient people jointly led to the formation of animal raising behaviors for utilitarian purposes. These commensal interactions involved both the actions of ancient people and the cooperative reactions of the animals themselves. Domestication processes were gradual and involved multiple repeated and progressive co-evolutionary developments.
Anhydramnios, but prenatally normal kidneys: renal tubular dysgenesis – patient with mutations in the renin-angiotensin system gene AGTR1
Authors: Kirch Naomi , Rocha Maria Linda , Wilke Mikosch , Bergmann Carsten , Schlembach Dietmar , Rossi Rainer
Published: January 2020

Background

Prenatally detected oligo- or even anhydramnios may – beside other reasons – be indicative for a diminished or absent urine production. The resulting clinical picture is a “Potter sequence” with arthrogrypotic joint contractions, a flat face and most importantly pulmonary hypoplasia. In severe cases this pulmonary hypoplasia can be life-limiting irrespective of the underlying lesion.

Case presentation

Our patient initially presented with anhydramnios and normal kidneys at external ultrasonography after 31 weeks of pregnancy. Following spontaneous birth after 37 weeks of gestation, the baby boy was born with all the clinical signs of a “Potter-sequence” along with a severe pulmonary hypoplasia leading to insufficient oxygenation and ventilation. Despite all measures taken, the child died after 8 h of life. Beside life-limiting pulmonary hypoplasia postmortem examination again confirmed macroscopically normal kidneys, but microscopy showed compact and variable sized glomeruli, numerically reduced and immature tubules, a structurally altered renal vascular bed and an expanded medullar interstitium. Immunohistochemical studies revealed the absence of proximal convoluted tubules, shortened proximal straight tubules beside an immaturity and dysmorphogenesis of the other segments of the nephron, and thus proved renal tubular dysgenesis (RTD) as the underlying disease. A homozygous mutation c.377G>C (p.Arg126Pro) in exon 2 of the AGTR1 gene was found, leading to the exchange of a highly conserved arginine to proline. This mutation has not been reported in public databases so far. As expected, both consanguineous parents were heterozygous for this mutation.

Conclusion

RTD has to be considered in an anuric fetus with apparently normal renal sonography in order to allow adequate prenatal counseling and – if indicated – palliative postnatal care.
Gridless Super-Resolution Direction-of-Arrival Estimation with Arbitrary Planar Sparse Array
Authors: Lu Aihong , Guo Yan , Yang Sixing
Published: January 2020

Two-dimensional (2D) direction-of-arrival (DOA) estimation with arbitrary planar sparse array has attracted more interest in massive multiple-input multiple-output application. The research on this issue recently has been advanced with the development of atomic norm technique, which provides super resolution methods for DOA estimation, when the number of snapshots is limited. In this paper, we study the problem of 2D DOA estimation from the sparse array with the sensors randomly selected from uniform rectangular array. In order to identify all azimuth and elevation angles of the incident sources jointly, the 2D atomic norm approach is proposed, which can be solved by semidefinite programming. However, the computational cost of 2D atomic norm is high. To address this issue, our work further reduces the computational complexity of the problem significantly by utilizing the atomic norm approximation method based on the concept of multiple measurement vectors. The numerical examples are provided to demonstrate the practical ability of the proposed method to reduce computational complexity and retain the estimation performance as compared to the competitors.
Designing Modern Compact Microstrip Planar Quadband Bandpass Filter for Hand Held Wireless Applications
Authors: Basit Abdul , Khattak M. Irfan
Published: January 2020

This paper presents a modern compact quad-band bandpass filter (BPF) using dual-mode stub loaded half wave (λ/2) resonators, where a couple of directly fed resonators are loaded with two identical inner resonators such that the direct fed resonators will act as feeding structure for the loaded resonators. Based on the proposed stub loaded resonators, a modern filter with seven transmission zeros (TZs) is designed by folding the two identical inner resonators. The proposed design has a symmetrical geometry, therefore even-odd mode analysis is used to predict the resonant frequencies of the passbands. The first and second passbands are obtained through fundamental odd and even modes respectively while the third one is achieved by placing loaded inner resonators in the proposed design. The second even harmonic of the direct fed resonators is utilized to achieve the fourth passband and is controlled by the stubs loaded at the middle of the resonators. The filter is simulated and fabricated for the purpose of validation, wherein a good agreement can be seen in both simulated and experimental results.

Published: January 2020

The Heterogeneous photocatalysis, increasingly used in effluent purification, is attracting more and more attention by the development of new photocatalytic materials based on semiconductors deposited on various supports. In this work, TiO2 supported on cellulosic fiber was prepared and characterized by different analytical techniques such as X-ray Photoelectron Spectrometry and Brunauer-Emmett-Teller surface area. Its photocatalytic activity was investigated for the degradation of Solophenyl Scarlet BNLE (SS), an organic pollutant present in textile effluents. Several conditions were investigated such as adsorption under UV and visible irradiation, catalyst recyclability, the simulated effluent pH and the presence of H2O2 as an oxidant agent. Results showed that under UV light, the removal of SS decreased significantly with increasing initial dye concentration. For an initial concentration of 5 mg/L, SS degradation was reached more than 95 % after 2 hours of treatment (neutral pH, T = 20 °C). The supported TiO2 on cellulose remains effective over four cycles of dye treatment. In the presence of H2O2, the degradation process was inhibited with increasing the molar ratio [H2O2]/[SS]0 from 5 to 30. The kinetic modeling showed that the removal of this pollutant followed a pseudo-first-order model (Langmuir-Hinshelwood) with a regression coefficient (R2) value of 0.984.
On some automorphic properties of Galois traces of class invariants from generalized Weber functions of level 5
Authors: Eum Ick Sun , Jung Ho Yun
Published: January 2020

After the significant work of Zagier on the traces of singular moduli, Jeon, Kang and Kim showed that the Galois traces of real-valued class invariants given in terms of the singular values of the classical Weber functions can be identified with the Fourier coefficients of weakly holomorphic modular forms of weight 3/2 on the congruence subgroups of higher genus by using the Bruinier-Funke modular traces. Extending their work, we construct real-valued class invariants by using the singular values of the generalized Weber functions of level 5 and prove that their Galois traces are Fourier coefficients of a harmonic weak Maass form of weight 3/2 by using Shimura’s reciprocity law.
An optimal fourth-order family of modified Cauchy methods for finding solutions of nonlinear equations and their dynamical behavior
Authors: Liu Tianbao , Qin Xiwen , Li Qiuyue
Published: January 2020

In this paper, we derive and analyze a new one-parameter family of modified Cauchy method free from second derivative for obtaining simple roots of nonlinear equations by using Padé approximant. The convergence analysis of the family is also considered, and the methods have convergence order three. Based on the family of third-order method, in order to increase the order of the convergence, a new optimal fourth-order family of modified Cauchy methods is obtained by using weight function. We also perform some numerical tests and the comparison with existing optimal fourth-order methods to show the high computational efficiency of the proposed scheme, which confirm our theoretical results. The basins of attraction of this optimal fourth-order family and existing fourth-order methods are presented and compared to illustrate some elements of the proposed family have equal or better stable behavior in many aspects. Furthermore, from the fractal graphics, with the increase of the value m of the series in iterative methods, the chaotic behaviors of the methods become more and more complex, which also reflected in some existing fourth-order methods.
New error bounds for linear complementarity problems of Σ-SDD matrices and SB-matrices
Authors: Hou Zhiwu , Jing Xia , Gao Lei
Published: January 2020

A new error bound for the linear complementarity problem (LCP) of Σ-SDD matrices is given, which depends only on the entries of the involved matrices. Numerical examples are given to show that the new bound is better than that provided by García-Esnaola and Peña [Linear Algebra Appl., 2013, 438, 1339–1446] in some cases. Based on the obtained results, we also give an error bound for the LCP of SB-matrices. It is proved that the new bound is sharper than that provided by Dai et al. [Numer. Algor., 2012, 61, 121–139] under certain assumptions.

Sr[B5O7F3] was investigated by infrared spectroscopy. Photoluminescence spectra of the doped compound revealed an Eu2+ 5d-4f emission in the UV regime peaking at 371 nm with a full width at half maximum (FWHM) of 21 nm upon excitation at 239 nm, which proves a weak coordination of europium by the anionic fluorooxoborate network.
Associations between Vaspin Levels and Coronary Artery Disease
Authors: Askin Lutfu , Tanriverdi Okan , Tibilli Hakan , Turkmen Serdar
Published: January 2020

The relationship between serum vaspin levels and metabolic or coronary artery disease is currently of interest for researchers. Although adipokine concentrations have been shown to be increased significantly in atherosclerotic lesions, the role adipokines in the atherosclerotic process remains to be elucidated. Vaspin is a new biological marker associated with obesity and impaired insulin sensitivity. Plasma vaspin concentration has been shown to correlate with the severity of coronary artery disease. Vascular inflammation triggered by vaspin inhibits atherogenesis by suppressing macrophage foam cell formation and vascular smooth muscle cell migration and proliferation. Vaspin also contributes to plaque stabilization by increasing collagen content and reducing the intraplaque macrophage to vascular smooth muscle cell ratio. The therapeutic goal concerning vaspin is to fight atherosclerosis and related diseases, as well as to maintain vascular health.
TheDrosophila melanogasterOrtholog of RFWD3 Functions Independently of RAD51 During DNA Repair
Authors: Carvajal-Garcia Juan , Gales Evan R , Ramsden Dale A , Sekelsky Jeff
Published: January 2020

Repair of damaged DNA is required for the viability of all organisms. Studies in Drosophila melanogaster, driven by the power of genetic screens, pioneered the discovery and characterization of many genes and pathways involved in DNA repair in animals. However, fewer than half of the alleles identified in these screens have been mapped to a specific gene, leaving a potential for new discoveries in this field. Here we show that the previously uncharacterized mutagen sensitive gene mus302 codes for the Drosophila melanogaster ortholog of the E3 ubiquitin ligase RING finger and WD domain protein 3 (RFWD3). In human cells, RFWD3 promotes ubiquitylation of RPA and RAD51 to facilitate repair of collapsed replication forks and double-strand breaks through homologous recombination. Despite the high similarity in sequence to the human ortholog, our evidence fails to support a role for Mus302 in the repair of these types of damage. Last, we observe that the N-terminal third of RFWD3 is only found in mammals, but not in other vertebrates or invertebrates. We propose that the new N-terminal sequence accounts for the acquisition of a new biological function in mammals that explains the functional differences between the human and the fly orthologs, and that Drosophila Mus302 may retain the ancestral function of the protein.
Mutational Analysis of N-Ethyl-N-Nitrosourea (ENU) in the Fission Yeast Schizosaccharomyces pombe
Authors: Hoyos-Manchado Rafael , Villa-Consuegra Sergio , Berraquero Modesto , Jiménez Juan , Tallada Víctor A
Published: January 2020

Forward genetics in model organisms has boosted our knowledge of the genetic bases of development, aging, and human diseases. In this experimental pipeline, it is crucial to start by inducing a large number of random mutations in the genome of the model organism to search for phenotypes of interest. Many chemical mutagens are used to this end because most of them display particular reactivity properties and act differently over DNA. Here we report the use of N-ethyl-N-nitrosourea (ENU) as a mutagen in the fission yeast Schizosaccharomyces pombe. As opposed to many other alkylating agents, ENU only induces an SN1-type reaction with a low s constant (s = 0.26), attacking preferentially O2 and O4 in thymine and O6 deoxyguanosine, leading to base substitutions rather than indels, which are extremely rare in its resulting mutagenic repertoire. Using ENU, we gathered a collection of 13 temperature-sensitive mutants and 80 auxotrophic mutants including two deleterious alleles of the human ortholog ATIC. Defective alleles of this gene cause AICA-ribosiduria, a severe genetic disease. In this screen, we also identified 13 aminoglycoside-resistance inactivating mutations in APH genes. Mutations reported here may be of interest for metabolism related diseases and antibiotic resistance research fields.
Red Light/Green Light, a Dual Fluorescent Protein Reporter System To Study Enhancer-Promoter Specificity in Drosophila
Authors: Camino Eric M , Weinstein Micheal L , List Mary P , Vellky Jordan E , Rebeiz Mark , Williams Thomas M
Published: January 2020

Enhancers activate gene transcription in spatial and temporal patterns by interactions with gene promoters. These elements typically reside distal to their target promoter, with which they must interact selectively. Additional elements may contribute to enhancer-promoter specificity, including remote control element sequences within enhancers, tethering elements near promoters, and insulator/boundary elements that disrupt off-target interactions. However, few of these elements have been mapped, and as a result, the mechanisms by which these elements interact remain poorly understood. One impediment is their method of study, namely reporter transgenes in which enhancers are placed adjacent to a heterologous promoter, which may circumvent mechanisms controlling enhancer-promoter specificity and long-range interactions. Here, we report an optimized dual reporter transgene system in Drosophila melanogaster that allows the simultaneous comparison of an enhancer’s ability to activate proximal and distal fluorescent reporter genes. Testing a panel of fluorescent transgenes in vivo, we found a two-protein combination that allows simultaneous measurement with minimal detection interference. We note differences among four tested enhancers in their ability to regulate a distally placed reporter transgene. These results suggest that enhancers differ in their requirements for promoter interaction and raise important practical considerations when studying enhancer function.

pest species and alter both the abundance and diversity of communities of their natural enemies. These impacts are probably the most conspicuous and notorious when the invaded host plant is a key commodity crop and the invasive pest an aphid (Hemiptera: Aphididae). Aphids have a remarkable
ability to overwhelm their plant hosts extremely rapidly owing to their parthenogenetic reproduction (i.e., daughters are clones of their mothers), live birth, and telescoping generations (i.e., the offspring of unborn aphids are already developing within their bodies). Aphids also attract
exceptionally diverse communities of predators and parasitoids, which are strongly attracted to the volatiles emitted from plants attacked by aphids, albeit the natural enemies' attraction to invasive aphids often requires a period of adaption to recognize a new prey. Hence, when new species
of aphids invade a new agroecosystem, their presence frequently creates an ?ecosystem earthquake' that can have profound implications for long-term stability of the system most directly affected by the invasive aphid as well as neighboring crops.
Regulatory Control and Management of Public Health Pesticides in South Africa
Authors: Utembe Wells
Published: January 2020

Pesticides used in residential settings may have harmful health effects. There are reports about pesticide poisoning in South Africa, especially among children under the age of five years. The Department of Agriculture, Forestry and Fisheries and the Department of Health use the Fertilizers,
Farm Feeds, Agricultural Remedies and Stock Remedies Act (Act No. 36) to ensure that pesticides are only registered after a rigorous science-based risk assessment. The Act 36 was designed primarily for agricultural pesticides. Therefore, guidelines have recently been developed to facilitate
registration of PHPs. However, these guidelines do not provide guidance on acceptable methods for estimating residential exposures. Furthermore, inadequate monitoring and regulation of pesticides have resulted in the use of highly toxic pesticides in residential and commercial settings. Responsible
government agencies and independent poisoning information centres (PICs) appear to lack the capacity routinely to report and investigate all pesticide-poisoning incidents adequately and comprehensively. Therefore, there is need to strengthen the capacity of responsible agencies as well as
to conduct a revision of Act 36 in order to address critical gaps with regards to the registration, monitoring and surveillance of PHPs.

Pests have been a constant threat to agriculture the world over. In the Fiji Islands where the major agricultural export commodity is raw sugar, the Sugarcane weevil borer is one such agricultural pest that poses a real threat to an already ailing industry. The Sugarcane weevil borer
(Rhabdoscelus obscure) is a pest originally found in Papua New Guinea whose introduction into Fiji has resulted in crop damage particularly to the soft variety of sugarcane found in Fiji. This review highlights the emergence of the weevil borer and explains a possible control that could
be implemented by the Fijian farmers. The current method of control in Fiji uses the split billet trap. While this method has been recognized as an economically viable method of controlling the spread of the weevil borer, it has not been completely effective in eradicating the pest. This paper
highlights and puts forth recommendations on other methods which could be used by the sugarcane industry.
Göç Türküleri: Yunanistan Mübadilleri Örneği
Authors: SÖYLEMEZ Mehmet
Published: January 2020

1923 yılında Türkiye ve Yunanistan arasındaki
Mübadele Antlaşmasına kadar Anadolu’nun farklı bölgelerinde yaşamış olan Hıristiyan
Ortodokslar hayatlarının pek çok alanında Türkçe kullanmışlardır. Kullanmış oldukları Türkçeyi sadece komşuları ile
iletişim için değil aynı zamanda çeşitli geleneksel tören ve özel günlerde de
(dini ritüeller, evlilik törenleri, ninniler, vb.) kullanmaları Ortodokslar
arasında zengin bir Türkçe sözlü geleneğin doğmasını sağlamıştır. Zorunlu
göçleri sırasında maddi anlamda yanlarında çok fazla bir şey götürme sansı
olmayan mübadiller, kültür ve kimliklerini yeni yaşayacakları yerlere
taşımışlardır. Yeni topraklara uyum noktasında yaşadıkları sorunlar, onların
şarkı ve türkülerine de yansımıştır. Belleklerin de getirdikleri türkülerin
yanında yeni vatanlarındaki sorunlar ve eski vatanlarına duydukları hasreti
içeren yeni türküler söylemeye başlamışlardır. Ağıt şeklinde olan bu eserler
göç sorunları, özlem ve hayıflanma gibi duyguları içeriyordu. Bu bağlamda
çalışma içerisinde özel arşivlerde ve alan çalışmalarında kayıt edilmiş olan
“Mübadele Türküleri” veya “Mübadele Ağıtları” 
adı verilen türküler ele alınmıştır. Yunanistan’daki mübadil köylerinde
ve özel arşivlerde karşılaşılan bu eserler, notaya alınırken, mübadelenin Yunan
tarafındaki etkilerinin sözlü kültür ve müzik kültürü üzerindeki etkilerinin
anlaşılması, bu türküler üzerinden değerlendirilmiştir.

Bu çalışmanın amacı
lise 11. ve 12. Sınıfa giden ergenlerin kişilik özellikleri ile ayrışma
bireyleşme arasındaki ilişkide akran ilişkilerinin aracı etkisini
belirlemektir. Çalışma grubunu Batman il merkezinde lise 11.ve 12 sınıfa giden
557 öğrenci oluşturmaktadır. Çalışmanın verileri LİSREL ve SPSS 22
programlarıyla analiz edilmiştir. İlk olarak çalışmada kullanılan ölçeklerin
doğrulayıcı faktör analizleri ve uyum iyiliği değerlerine bakıldı. Analiz
sonucuna göre bütün ölçeklerin doğrulayıcı faktör değerlerinin (p<.01) düzeyinde
anlamlı olduğu ortaya çıkmıştır. Ölçeklerin uyum iyiliği değerleri ise çalışma
için yeterli uyum değerlerine sahip olduğu saptanmıştır. Analizler sonucunda
lise öğrencilerinin kişilik özellikleri ile ayrışma bireyleşme arasındaki
ilişkide akran ilişkilerinin negatif yönde aracılık ettiği ortaya çıkmıştır.
Elde edilen sonuçlara göre, lise öğrencilerinin ayrışma bireyleşme düzeyleri
yükseldikçe, akran ilişkilerinin düşüş gösterdiği saptanmıştır.
İletişim Perspektifinden Siyasal İletişim ve Seçim Kampanyaları
Authors: TUNCA Elif Asude
Published: January 2020

Siyaset ve iletişim
bilimlerinin kesişim noktasında bulunan siyasal iletişim üzerine yapılan çalışmalar,
eleştirel ve Anglo-Amerikan olmak üzere 2 ana yaklaşım çerçevesinde
yürütülmektedir. Anglo-Amerikan yaklaşım çerçevesinde ele alınan çalışmalar
iletişimi, iletişim araçlarının kamuoyunun oluşumundaki etkilerini konu yapmış
çalışmalardır. Buna karşılık, eleştirel kuram pespektifinden siyasal iletişim,
deneysel çalışmaları içermekle birlikte saf ampirizme karşıdır ve eleştireldir.
Bu çalışmada, iletişim bilimi genelinde siyasal iletişim kavramı, unsurları ve
tarihsel arka planı betimleyici bir çerçevede işlenmektedir. Çalışma kapsamında
siyasal iletişimin kavramsal boyutunun yanısıra, siyasal iletişimin aktörleri,
seçim kampanyalarında kullanılan iletişim yöntem ve araçları Türkiye’de
özellikle 1946 – 1995 yılları arasındaki yürütülen seçim kampanları örnekleri
özelinde ele alınarak Anglo-Amerikan yaklaşımdan etkilenişi ortaya konmaya
çalışılmıştır.

 Küresel iletişim perspektifinden siyasal iletişim ve seçim
kampanyalarının ABD’deki uygulamaları çerçevesinde Türkiye’deki yansımalarına
bakıldığında görülmektedir ki siyasal partilerin seçmenleriyle kurdukları
iletişim seçim dönemlerinde yoğunlaşmakta, gerek kullanılan yöntem gerek
kullanılan iletişim araçları ve gerekse gönderilen mesaj kapsamları diğer
dönemlerden daha farklı ve yoğun olmaktadır.
Batman Yerel Basınında Göçmenlerin Temsili Üzerine Bir Analiz
Authors: TÜRK Emrullah
Published: January 2020

Türkiye,
son yıllarda sayıları hızla artan ve farklı ülkelerden gelen göçmenlere ev
sahipliği yapmaktadır. Bu süreç beraberinde göçmenlerle ev sahibi konumunda
olan halkın etkileşimini doğurmaktadır. İşte bu etkileşimin nicelik ve niteliği,
uyum ya da çatışma sürecini belirlemektedir. Türkiye’ye yönelen bu göçmenlerin
herhangi bir çatışma zemini oluşmadan uyum süreçlerine katkı sunmak amacıyla,
kamu kurumları ile sivil toplum örgütleri çeşitli faaliyetler yürütmektedir.
Ayrıca ulusal ya da yerel basın kuruluşları da yaptıkları haberlerle bu sürecin
olumlu ya da olumsuz yönde şekillenmesinde rol oynamaktadır.

Bu
çalışmanın amacı, Batman yerel basınında göçmenlerle alakalı haberlerin ele
alınış biçimlerini değerlendirmektir. Çalışma, nitel araştırma kapsamında,
2012-2018 döneminde Batman’daki yerel gazetelerde göçmenlerle alakalı yüzlerce
haber arasından araştırma bağlamından kopuk ve tekrara düşen haberler
elendikten sonra toplamda 67 adet haberin söylem analizine dayanmaktadır.

Çalışma
bulgularına göre, Batman yerel basınında göçmenlere dair haberlerin ele alınış
biçimlerinde yoğun benzerlikler bulunmakta ve temsiller büyük oranda olumlu bir
şekilde sunulmaktadır. Göçmenlere ilişkin haberlerin genellikle “sıkıntı”,
“sorun” ve “mağduriyet” başlıkları etrafında şekillendiği görülmektedir. Son
olarak, yerel basının bu yaklaşımın, göçmenlerin uyum sürecine katkı sağladığı
söylenebilir.
