Desterceirização e flexibilidade: retorno à integração vertical e o impulso à polivalência.
Authors: Dias Sabrina de Oliveira Moura 
Published: June 2020

Esta pesquisa tem por objetivo analisar o processo de flexibilização da organização do trabalho a partir de mudanças na gestão dos efetivos, tais como a terceirização, a destercerização e a polivalência. A partir do estudo de caso de uma unidade de produção siderúrgica buscar-se-á compreender a forma como a desterceirização aliada à polivalência permite a expansão da flexibilização e a redução de parte das resistências dos trabalhadores ao acúmulo de funções. Esta pesquisa foi elaborada com base em entrevistas com trabalhadores e ex-trabalhadores da empresa e de suas prestadoras de serviços, e com sindicalistas e ex-sindicalistas do Sindicato dos Metalúrgicos. Foram utilizados ainda na elaboração do texto os boletins sindicais e ações ajuizadas na Justiça do Trabalho relativas à desterceirização e à prática da polivalência na empresa.A desterceirização e o retorno a uma gestão mais verticalizada dos efetivos se desenvolveu em sintonia com o aumento da polivalência, expandindo a flexibilidade e reduzindo os postos de trabalho.
Las víctimas frente al sufrimiento colectivo: estructuras morales y sacralizaciones emergentes.
Authors: Vecchioli Virginia , Catoggio María Soledad 
Published: June 2020

Los artículos reunidos aquí muestran cómo las formas de movilización de las víctimas y la gestión del sufrimiento colectivo están atravesadas por su relación con el espacio de lo sagrado, entendido en un sentido amplio y diverso. Presentan en forma novedosa las diversas articulaciones entre las gramáticas de lo sagrado y el activismo de sobrevivientes y familiares de víctimas, el lugar de los especialistas en la consagración de sus figuras en el espacio público y las políticas de gestión de su sufrimiento. Su lectura nos permite recorrer las acciones del movimiento negro y los colectivos de familiares de la violencia urbana en Brasil, las prácticas de los curas identificados con la opción por los pobres y la emergencia de organizaciones de familiares de víctimas de la violencia institucional en la Argentina, el surgimiento de nuevas formas de espiritualidad y gestión del pasado de las víctimas del terrorismo de Estado en Argentina y Uruguay, las iniciativas del movimiento de familiares de víctimas de la violencia terrorista en País Vasco, las estrategias de protección y/o denuncia de mujeres víctimas de violencia sexual en Argentina y Paraguay y los emprendimientos de los colectivos que gestionan la salida del apartheid en Sudáfrica. De la lectura de los trabajos se destaca la forma en que la intervención pública de estos colectivos instituye regímenes de verdad que tensionan y/o resignifican las reivindicaciones clásicas de memoria, verdad y justicia y los modos de gestión del pasado establecidos a partir de la gramática binaria víctima-victimario.

El presente artículo es un fragmento del Trabajo Final de Máster que se defendió en septiembre de 2017, fue tutorizado por el profesor D. Gil Pecharromán en el marco del Máster de la España Contemporánea en el Contexto Internacional de la UNED. El trabajo consistió en una investigación sobre la importancia que tuvo la asociación de veteranos de guerra Hermandad de Alféreces Provisionales[1], cuya creación marcó la agenda política de la dictadura de finales de los años 50. Con el trabajo, resumido en el artículo, se pretendía lograr un triple objetivo: llenar el vacío historiográfico existente en referencia a la creación de la HAP, aportar documentación nueva que apoye o no la tesis dominante de que la HAP fue una creación del Ejército como altavoz político en la escena pública; y por último, la tesis inicial del trabajo era que la HAP surgió como una idea espontánea de un grupo de veteranos alféreces provisionales, y que únicamente cuando esa idea se convirtió en una asociación con millares de miembros, el Ejército intervino para mediatizarla.his article is a fragment of a bigger research about the origin and initally importance of a civil war veteran association called «Hermandad de Alféreces Provisionales», whose apparition was really important in Francoist politics of the fifties. The «Alféreces Provisionales» were the core of the Francois army during the Spanish Civil War, and later on they were formed an important lobby inside the dictatorship regime.With the thesis, summarized in this article, there were three objectives to achieve: fill the lack of knowledge about the creation of the «HAP», get new evidence to support or not the most accepted theory, that says that the «HAP» was a creation of the army as a way of getting more influence in politics; and finally, the initial theory of the thesis was that the «HAP» was an unplanned project of the veterans, and only when they became a successful association, the Army intervened to control them.[1] En adelante HAP.

Published: June 2020

En forskergruppe har fulgt 73 erhvervsskolelærere på efteruddannelse som gennem undervisningseksperimenter har udforsket og udviklet didaktisk praksis rettet mod udvikling af elevernes innovative og entreprenørielle kompetencer.
Ny forskning viser, at elever fra GF1 til svendeprøve - også de elever, der har faglige udfordringer, motiveres og engageres, når der gøres op med den traditionelle undervisningsform og i stedet fokuseres på en mere eksperimenterende og intensiv undervisningsform, hvor det er eleverne, der sætter retning.
Et forskerteam har fulgt læreres undervisningseksperimenter fra både SOSU-, Merkantile- og Tekniske skoler. I gennem interview og observation er der fundet didaktiske greb og forhold i entreprenørskabsundervisning, som gør en forskel for elevernes læring og motivation.
Konklusionen i analysen peger på, at det øger intensiteten og engagementet blandt eleverne, når de får mulighed for arbejde med læring ift. noget, der er personligt meningsfuldt, involverer handling, samarbejde med andre elever, kreativitet og autentiske opgaver, der værdsættes i omverdenen.
Fem fokuspunkter:1.Det udvider læringsindholdet med eleveksperimenter, hvor eleverne ikke bare lærer mere eller er mere motiverede, men de lærer intensivt gennem udforskning af og afprøvning i praksis
2.Åbenhed om indhold og form i undervisningen giver mere indflydelse og selvbestemmelse til elever. Inddragelse af virksomheder og institutioner som de kan samarbejde med understøtter dette
3. Støtte undervejs ved at forholde sig undrende, undersøgende og som medskaber i processen, giver plads til elevers selvigangsatte aktiviteter og
4. Gruppearbejde, hvor eleverne har fælles ansvar og træffer de vigtigste beslutninger sammen, betyder, at alle trækker på samme hammel – trods individuelle forskelle.
5.Inklusion gennem samarbejde, hvor eleverne oplever anerkendelse og aktiv deltagelse af alle, minimerer sociale og faglige udfordringer.
Resultaterne peger på, at entreprenørskabsundervisning åbner for, at elever får medindflydelse på både indhold, tidsforbrug, slutproduktet og evalueringsform. Det gør eleverne mere engagerede og deltagende i undervisningen. De tager medansvar for deres læring og føler et ejerskab over processen
Den transnationale uddannelsesrevolutions opløsning af pædagogikkens egenart
Authors: Pio Frederik 
Published: June 2020

Artiklen perspektiverer på den almene pædagogiks aktuelle, pressede tilstand, i lyset af de centrale, transnationale udviklingstendenser inden for uddannelsesstyring der har gjort sig gældende de sidste ca. 25-30 år. Dette gøres, ved at tage afsæt i de såkaldte antinomier, som en række pædagogiske forskere har forholdt sig til som definerende for moderne pædagogik. Denne tematik blevet sat på dagsordenen af aktuelle uddannelsesforskere som bl.a. Alexander von Oettingen; Michael Uljens; Lars Løvlie; Gert Biesta, Birgit Schaffar og Dietrich Benner. Oettingen ser nærmere bestemt spørgsmålet om pædagogisk professionalitet som spaltet i fire antinomiske paradokser, der angår (i) Rationalisering (sociologi); (ii) Pluralisering (kultur); (iii) Individualisering (psykologi) og (iv) Civilisering (natur, filosofi) (Oettingen i Kristensen & Laursen: 2012, s. 531-549). Disse pædagogiske paradoksaliteter har en rod bl.a. hos Kant, Rousseau og Herbart. Artiklen søger gennem fokusering af sådanne pædagogiske antinomier eller paradokser (omkring pædagogikkens videns-, værdi-, institutions- samt handlings-problem, jf. Oettingen: 2010) at vise, hvorledes den transnationale uddannelsesrevolution de sidste 25-30 år har udtyndet den almenpædagogiske undermuring af begreberne: I. professionalitet, II. læring, III. autenticitet og IV. dannelse. Dermed fokuseres de almenpædagogiske problemstillinger der kendetegner disse fire begreber. Dette gøres for at vise, hvorledes den transnationale uddannelsesstyring i dette lys udgør en bekymrende afvikling eller sammenklapning af pædagogikkens almene grundtræk.
La formación de investigadores con tecnologías digitales: una revisión sistemáticade la literatura especializada
Authors: Palacios-Díaz Rosalba , Escudero-Nahón Alexandro 
Published: June 2020

La educación superior es uno de los tipos de educación más influidos por las tecnologías digitales. Esta situación, al tiempo que presenta varias ventajas, también impone muchos desafíos. La educación de tipo superior en México se conforma por tres niveles: técnico superior, licenciatura y posgrado. En los estudios de posgrado es donde se forman, propiamente, los investigadores en ciernes. No obstante, no existe abundante literatura especializada sobre los desafíos que impone las tecnologías digitales para formar a los investigadores en, relativamente, poco tiempo (de uno a cuatro años). Este estudio documental aplicó el método de investigación llamado Revisión Sistemática para identificar los hallazgos más relevantes que los especialistas han analizado sobre el uso de las tecnologías digitales por parte de los investigadores en formación. La Revisión Sistemática se realizó en cuatro fases: búsqueda documental en bases de datos científicos, descripción de los criterios de inclusión y exclusión de textos, análisis y categorización y, finalmente, discusión y propuesta. Los resultados más relevantes sugieren que los investigadores en formación lidian con varios problemas al momento de usar tecnología digital, entre los que destacan: la preparación incorrecta de los espacios de trabajo para la producción de conocimiento; la necesidad de generar articulaciones espontáneas entre las herramientas digitales disponibles, vigentes e interoperables; y la configuración adecuada de las redes de investigación, entre otros. Finalmente, se propone un proceso de uso de las tecnologías digitales que recorre, de forma itinerante, tres etapas durante la formación del investigador: preparación, uso y distribución.

Searching for a signature involving 10 genes to predict the survival of patients with acute myelocytic leukemia through a combined multi-omics analysis
Authors: Zhuang Haifeng , Chen Yu , Sheng Xianfu , Hong Lili , Gao Ruilan , Zhuang Xiaofen 
Published: June 2020

Background
Currently, acute myelocytic leukemia (AML) still has a poor prognosis. As a result, gene markers for predicting AML prognosis must be identified through systemic analysis of multi-omics data.

Methods
First of all, the copy number variation (CNV), mutation, RNA-Seq, and single nucleotide polymorphism (SNP) data, as well as those clinical follow-up data, were obtained based on The Cancer Genome Atlas (TCGA) database. Thereafter, all samples (n = 229) were randomized as test set and training set, respectively. Of them, the training set was used to screen for genes related to prognosis, and genes with mutation, SNP or CNV. Then, shrinkage estimate was used for feature selection of all the as-screened genes, to select those stable biomarkers. Eventually, a prognosis model related to those genes was established, and validated within the GEO verification (n = 124 and 72) and test set (n = 127). Moreover, it was compared with the AML prognosis prediction model reported in literature.

Results
Altogether 832 genes related to prognosis, 23 related to copy amplification, 774 associated with copy deletion, and 189 with significant genomic variations were acquired in this study. Later, genes with genomic variations and those related to prognosis were integrated to obtain 38 candidate genes; eventually, a shrinkage estimate was adopted to obtain 10 feature genes (including FAT2, CAMK2A, TCERG1, GDF9, PTGIS, DOC2B, DNTTIP1, PREX1, CRISPLD1 and C22orf42). Further, a signature was established using these 10 genes based on Cox regression analysis, and it served as an independent factor to predict AML prognosis. More importantly, it was able to stratify those external verification, test and training set samples with regard to the risk (P < 0.01). Compared with the prognosis prediction model reported in literature, the model established in this study was advantageous in terms of the prediction performance.

Conclusion
The signature based on 10 genes had been established in this study, which is promising to be used to be a new marker for predicting AML prognosis.
A Statistically Driven Spectral Method for Deriving Reservoir Properties Using 3D Seismic Data and Well Log Suites
Authors: B. Olaseni V. , S. Onifade Y. , O. Airen J. , Adeoti L. 
Published: June 2020

A statistically driven spectral method was carried out on 3D seismic data and well logs in ‘’VIC’’ Field within the Niger Delta with the aim of deriving reservoir properties and delineating stratigraphic features using edge detection attributes like coherence so as to have a better and clearer view of subsurface structure of a reservoir interval that possesses hydrocarbon using Spectral method.
A suite of data consisting of seismic sections and composite logs comprising Gamma-ray, Resistivity, Spontaneous Potential, Sonic Time and Porosity logs (density and Neutron) were utilized to identify reservoir interval on log signature across wells 4 and 5 and the reservoir interval obtained was between 11,164 feet and 11,196 feet. Edge detection attribute like coherence was computed from the amplitude data in time domain and transformed to frequency domain using Fourier Transform tool in MATLAB. In order to display well log in time, well to seismic tie was carried out using check shot data which was used as time to depth relationship.
The analysis of the spectral domain shows distinct bright spots that vary with measured depth due to variation in fluid and formation properties. The results led to an enhancement of seismic data interpretation in the field of study due to a spectral technique method that was applied to calculate the frequency slices. The results indicate that the spectral domain in coherence attributes revealed better geological features and the reservoir character such as faults and fractures.
Frequency domain gives better geological maps as it is used to filter data, which means it is an enhancement of hidden features in time domain and gives a smoother variation of the features that has low frequency values. A reservoir with low frequency values is a sandy environment showing stratigraphy features. Hence, the reservoir is suspected to be a channel fill reservoir. This implies that Spectral domain (frequency) defines major geological areas of the ‘’VIC’’ field and gives much clearer image of the reservoir features within the field than in time domain.

Published: June 2020

The measurement of magnetic field intensity within Captain Elechi Amadi Polytechnic, Rumuola was carried out with the aid of a handheld Bentech (GM-3120) Model Electromagnetic Radiation Metre. A total of 6 sampled locations were recorded; randomly with six distinct measurement and their coordinates at each of the sampled location with the aid of the global system position satellite (GPS) device. The measurement took place between 2017 November to 2018 March. A minimum value of 0.3417 0.65 T was recorded at the Administrative Block and a maximum value of 1.9767 1.43 T at the Business Centre. The overall mean values of all the sampled locations all fall below the recommended limit for the outdoor magnetic field intensity exposure of 100T of the International Commission of Non-Ionizing Radiation Protection (ICNIRP). The outcome of the measurement reveals that the exposure to magnetic field intensity to staffs, students and commercial workers within the campus of the Captain Elechi Amadi Polytechnic poses no health hazard.

Published: June 2020

The activity concentration and Annual Effective doses of 40K, 226Ra, and 232Th in some edible mushroom species (Cantharellus cibarius, Agaricus campestris, Termitomyces robustus) found in three Local Government Areas of Benue state-Nigeria were determined using Gamma Spectrometry; the 1460KeV gamma-radiation of 40K was used to determine the concentration of 40K, gamma transition energy of 1764.5KeV 214Bi was used to determine the concentration of 226R, while the gamma transition energy of 2614KeV 208TI was used to determine the concentration of 232Th. The activity concentration due to 226Ra, 232Th and 40K in the samples ranged from 10.06±1.6 - 14.19±3.01Bqkg-1; 10.88±2.65 to 15.38±4.30Bqkg-1and 202.31±1.4 to 318.44±3.20Bqkg-1 respectively; the highest activity due to 226Ra was found in Termitomyces robustus grown in Gboko; that due to 232Th was recorded in Agaricus campestris grown in Buruku L.G.A., while the highest activity concentration due to 40K was recorded in Termitomyces robustus found in Buruku. Generally, 40K recorded the highest activity concentration in each mushroom species examined. Annual Effective Dose from these species sampled ranges from 0.0006952mSvy-1 (in Makurdi- Termitomyces robustus species) - 0.0008467mSvy-1 (in Buruku Termitomyces robustus species). The average effective dose value of 0.00788±0.000186mSvy-1 obtained in this work is below the maximum permissible level established by ICRP (1996). Thus, these mushrooms species will not pose any apparent risk to human health.

Published: June 2020

Aims: To investigate The effect of concentration on organic solar cell efficiency.
Study Design: Polymer and natural dye Eriochrome black T were deposited on ITO glass substrate, and then the resulted cells were tested for characteristics.
Place and Duration of Study: International University of Africa Faculty of Pure and applied science-Department of Physics collaboration with University Medical Science and Technology- Alawia Centre and AlNilain University – Faculty of Science and Technology – Department of Physics, between March 2016 and May 2017.
Methodology: we have dye of different colour, we select three colours the dye, and then UV-visible spectrometer used for absorption spectra. After that, the relation between absorption and wavelength, absorption coefficient, and energy band gap were found graphically. Finally, cells were designed on ITO glass substrate by using spin coating deposition. Characteristics measured.
Results: The relation between the Eriochrome black T concentration of dye for three samples are 6.67, 6.03, and 5.43 g/L, and the corresponding efficiencies for dark blue are 0.091, 0.090 and 0.229 respectively. The efficiencies of yellow Eriochrome Black T are 0.228, 0.193 and 0.181. And the efficiencies of red Eriochrome Black T are 0.246, 0.235 and 0.193. The decreases of efficiency due to the decreases of Eriochrome Black T concentration is related to the direct relation between Eriochrome Black T concentration and solar cell.
Conclusion: The efficiency of dye-sensitised solar cells can be increased by increasing the Eriochrome Black T dye concentrations at least within the examined range. The Eriochrome Black T dye type also affect efficiency. This includes the transparency of the Eriochrome Black T dye beside the value of the Fermi energy. In addition to the relative positions of highest occupied molecular orbitals (HOMO) and lowest unoccupied molecular orbits (LUMO) to nearby layers.
