¿De la educación para la castidad a la inclusión de las minorías sexuales? Libros de texto sobre ética (dôtoku) e higiene (hoken) en el Japón contemporáneo

UNESCO recommends that textbooks should be used to help students dismiss stereotypes. By containing stories that give prominence to multiple gender categories (men, women, transgender, for example) and various sexual orientations, such as lesbian, gay, and bisexual, textbooks can show the prejudicial effect of the division of humankind into two sexes and the imposition of heterosexuality. However, even today, schoolbooks in many countries provide very little space for this topic. Japan is not an exception. Since the emergence of the modern school system in the nineteenth century, sexual education, especially topics related to sexual minorities, has been absent from schoolbooks. Due to the international and national gay rights movement and several legal changes regarding sex reassignment surgery, the situation started to change in the late 1990s. In this article we overview the changes in curriculum guidelines relating to sexualities from 1958 to 2017 and critically analyse the latest school textbooks (issued after 2017) on hygiene (grade 4) and on ethics (grade 7-8). We discuss whether sex education in Japan, which was called “chastity education” (junketsu kyōiku) until 1972 and has previously been dominated by heteronormative values, has indeed transformed into “progressive” education that embraces sexual diversities. Referencing official documents of the Ministry of Education, we will argue that the Ministry of Education is medicalizing sex change surgery and labelling transgender children as “children with special needs”, while still imposing existing heteronormative gender norms on other non-minority children.La UNESCO recomienda que los libros de texto se utilicen para ayudar a los alumnos a descartar los estereotipos. Al contener historias que dan protagonismo a múltiples categorías de género (hombres, mujeres, transexuales, por ejemplo) y a diversas orientaciones sexuales, como lesbiana, gay y bisexual, los libros de texto pueden mostrar el efecto perjudicial de la división de la humanidad en dos sexos y la imposición de la heterosexualidad. Sin embargo, aún hoy, los libros de texto de muchos países dedican muy poco espacio a este tema. Japón no es una excepción. Desde la aparición del sistema escolar moderno en el siglo XIX, la educación sexual, especialmente los temas relacionados con las minorías sexuales, ha estado ausente de los libros de texto. Debido al movimiento internacional y nacional por los derechos de los homosexuales y a varios cambios legales relacionados con la cirugía de reasignación de sexo, la situación empezó a cambiar a finales de la década de 1990. En este artículo hacemos un repaso de los cambios en las directrices curriculares relacionadas con las sexualidades desde 1958 hasta 2017 y analizamos críticamente los últimos libros de texto escolares (publicados después de 2017) sobre higiene (cuarto curso) y sobre ética (séptimo y octavo curso). Debatimos si la educación sexual en Japón, que se denominó "educación para la castidad" (junketsu kyōiku) hasta 1972 y que anteriormente ha estado dominada por valores heteronormativos, se ha transformado realmente en una educación “progresista” que abarca las diversidades sexuales. Haciendo referencia a documentos oficiales del Ministerio de Educación, argumentaremos que este está medicalizando la cirugía de cambio de sexo y etiquetando a los niños transexuales como “niños con necesidades especiales”, mientras sigue imponiendo las normas de género heteronormativas existentes a otros niños no pertenecientes a minoría

Morphometric human embryonic brain features according to developmental stage

Objectives: The present study investigated linear, area, and volume measurements of human brain samples according to Carnegie stages (CS) in an attempt to select suitable morphometric features that reflect embryonic development. Methods: Using magnetic resonance imaging, we measured seven linear segments, three separate areas, and three regional volumes in 101 samples between CS13 and 23. Brain volume was determined via manual segmentation of the magnetic resonance image, whereby a formula was generated to estimate the volume of each linear measurement. Results: All parameters correlated with crown-rump length. Bitemporal length and mesencephalic height increased linearly according to the CS, and a high correlation between bitemporal length and both whole-brain (r=0.98) and prosencephalon (r=0.99) volumes was found when brain cavity volume was excluded. Conclusion: Morphometric data related to human embryonic stages are valuable for correcting and comparing sonographic data. The present approach may contribute to improvements in prenatal diagnostics by enabling the selection of more suitable measurements during early embryonic stages

MEASUREMENT OF ANTIOXIDANT POWER OF MOUTHWASHES INDICATED IN STOMATITIS

ABSTRACTObjective: Hospital formulations containing allopurinol and rebamipide are used in the prophylactic and therapeutic management of stomatitis,owing to their antioxidant powers. The objective of this study was to measure the antioxidant powers of Zyloric® tablets (allopurinol), Mucosta®tablets (rebamipide), different hospital formulations indicated in the management of stomatitis (allopurinol and rebamipide mouthwashes), andAzulene® 0.4% for Gargle (sodium azulene sulfonate).Methods: We measured the antioxidant powers of Zyloric® and Mucosta® tablets, all hospital formulations indicated in the management of stomatitis(allopurinol and rebamipide mouthwashes), and the widely used Azulene® 0.4% for Gargle by employing the biological antioxidant potential test. Wecompared the efficacy of each of these drugs in the management of stomatitis.Results: Azulene® 0.4% for Gargle was found to have stronger antioxidant power than Zyloric® (100 mg) and Mucosta® (100 mg) tablets dissolved inwater. The antioxidant power of the solvent used in hospital formulations was similar to that of the prepared hospital formulation. Antioxidant powerof the drugs themselves was not observed in both the allopurinol and rebamipide mouthwashes.Conclusion: The antioxidant power of the drugs was not observed in both the allopurinol and rebamipide mouthwashes; therefore, hospitalformulations used as antioxidants were found to be less effective in the treatment of stomatitis. However, Azulene® 0.4% for Gargle was found to beuseful in the prophylactic and therapeutic management of stomatitis, owing to its antioxidant, and anti-inflammatory effects.Keywords: Stomatitis, Bone alkaline phosphatase-test, Allopurinol mouthwash, Rebamipide mouthwash, Azulene® 0.4% for Gargle, Antioxidant powe

Induced pseudoscalar coupling of the proton weak interaction

The induced pseudoscalar coupling $g_p$ is the least well known of the weak coupling constants of the proton's charged--current interaction. Its size is dictated by chiral symmetry arguments, and its measurement represents an important test of quantum chromodynamics at low energies. During the past decade a large body of new data relevant to the coupling $g_p$ has been accumulated. This data includes measurements of radiative and non radiative muon capture on targets ranging from hydrogen and few--nucleon systems to complex nuclei. Herein the authors review the theoretical underpinnings of $g_p$, the experimental studies of $g_p$, and the procedures and uncertainties in extracting the coupling from data. Current puzzles are highlighted and future opportunities are discussed.Comment: 58 pages, Latex, Revtex4, prepared for Reviews of Modern Physic

Final Test at the Surface of the ATLAS Endcap Muon Trigger Chamber Electronics

For the detector commissioning planned in 2007, sector assembly of the ATLAS muon-endcap trigger chambers and final test at the surface for the assembled electronics are being done in CERN and almost completed. For the test, we built up the Data Acquisition (DAQ) system using test pulse of two types and cosmic rays in order to check functionality of the various aspects of the electronics mounted on a sector. So far, 99% of all 320,000 channels have been tested and most of them were installed into the ATLAS cavern. In this presentation, we will describe the DAQ systems and mass-test procedure in detail, and report the result of electronics test with some actual experience

The First Result of Global Commissioning of the ATLAS Endcap Muon Trigger System in ATLAS Cavern

We report on the ATLAS commissioning run from the view point of the Thin Gap Chamber (TGC), which is the ATLAS end cap muon trigger detector. All the TGC sectors with on-detector electronics are going to be installed to the ATLAS cavern by the end of September 2007. To integrate all sub-detectors before the physics run starting from early 2008, the global commissioning run together with other sub-detectors has been performed from June 2007. We have evaluated the performance of the complete trigger chain of the TGC electronics and provide the trigger signal using cosmic-ray to the sub-systems in the global run environment

Jet energy measurement with the ATLAS detector in proton-proton collisions at root s=7 TeV

The jet energy scale and its systematic uncertainty are determined for jets measured with the ATLAS detector at the LHC in proton-proton collision data at a centre-of-mass energy of √s = 7TeV corresponding to an integrated luminosity of 38 pb-1. Jets are reconstructed with the anti-kt algorithm with distance parameters R=0. 4 or R=0. 6. Jet energy and angle corrections are determined from Monte Carlo simulations to calibrate jets with transverse momenta pT≥20 GeV and pseudorapidities {pipe}η{pipe}<4. 5. The jet energy systematic uncertainty is estimated using the single isolated hadron response measured in situ and in test-beams, exploiting the transverse momentum balance between central and forward jets in events with dijet topologies and studying systematic variations in Monte Carlo simulations. The jet energy uncertainty is less than 2. 5 % in the central calorimeter region ({pipe}η{pipe}<0. 8) for jets with 60≤pT<800 GeV, and is maximally 14 % for pT<30 GeV in the most forward region 3. 2≤{pipe}η{pipe}<4. 5. The jet energy is validated for jet transverse momenta up to 1 TeV to the level of a few percent using several in situ techniques by comparing a well-known reference such as the recoiling photon pT, the sum of the transverse momenta of tracks associated to the jet, or a system of low-pT jets recoiling against a high-pT jet. More sophisticated jet calibration schemes are presented based on calorimeter cell energy density weighting or hadronic properties of jets, aiming for an improved jet energy resolution and a reduced flavour dependence of the jet response. The systematic uncertainty of the jet energy determined from a combination of in situ techniques is consistent with the one derived from single hadron response measurements over a wide kinematic range. The nominal corrections and uncertainties are derived for isolated jets in an inclusive sample of high-pT jets. Special cases such as event topologies with close-by jets, or selections of samples with an enhanced content of jets originating from light quarks, heavy quarks or gluons are also discussed and the corresponding uncertainties are determined. © 2013 CERN for the benefit of the ATLAS collaboration

Measurement of the inclusive and dijet cross-sections of b-jets in pp collisions at sqrt(s) = 7 TeV with the ATLAS detector

The inclusive and dijet production cross-sections have been measured for jets containing b-hadrons (b-jets) in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV, using the ATLAS detector at the LHC. The measurements use data corresponding to an integrated luminosity of 34 pb^-1. The b-jets are identified using either a lifetime-based method, where secondary decay vertices of b-hadrons in jets are reconstructed using information from the tracking detectors, or a muon-based method where the presence of a muon is used to identify semileptonic decays of b-hadrons inside jets. The inclusive b-jet cross-section is measured as a function of transverse momentum in the range 20 < pT < 400 GeV and rapidity in the range |y| < 2.1. The bbbar-dijet cross-section is measured as a function of the dijet invariant mass in the range 110 < m_jj < 760 GeV, the azimuthal angle difference between the two jets and the angular variable chi in two dijet mass regions. The results are compared with next-to-leading-order QCD predictions. Good agreement is observed between the measured cross-sections and the predictions obtained using POWHEG + Pythia. MC@NLO + Herwig shows good agreement with the measured bbbar-dijet cross-section. However, it does not reproduce the measured inclusive cross-section well, particularly for central b-jets with large transverse momenta.Comment: 10 pages plus author list (21 pages total), 8 figures, 1 table, final version published in European Physical Journal

Single hadron response measurement and calorimeter jet energy scale uncertainty with the ATLAS detector at the LHC

The uncertainty on the calorimeter energy response to jets of particles is derived for the ATLAS experiment at the Large Hadron Collider (LHC). First, the calorimeter response to single isolated charged hadrons is measured and compared to the Monte Carlo simulation using proton-proton collisions at centre-of-mass energies of sqrt(s) = 900 GeV and 7 TeV collected during 2009 and 2010. Then, using the decay of K_s and Lambda particles, the calorimeter response to specific types of particles (positively and negatively charged pions, protons, and anti-protons) is measured and compared to the Monte Carlo predictions. Finally, the jet energy scale uncertainty is determined by propagating the response uncertainty for single charged and neutral particles to jets. The response uncertainty is 2-5% for central isolated hadrons and 1-3% for the final calorimeter jet energy scale.Comment: 24 pages plus author list (36 pages total), 23 figures, 1 table, submitted to European Physical Journal
