Catolicismo social y orientación ideológica política de izquierda en Colombia: una puerta abierta por Concilio Vaticano II

El ´aggiornamento´ de la Iglesia Católica con los signos de los tiempos, llevó a la institución eclesiástica a proponer, a la luz del Evangelio, soluciones cristianas para los problemas del género humano en el mundo moderno. El catolicismo se reconcilio así con el mundo moderno, trasladándose de su posición intransigente, propia del proceso de Romanización de la Iglesia Católica del siglo XIX, hacia una apertura de las ventanas de la Iglesia para que entrara el aire del mundo. Con el Concilio Ecuménico Vaticano II, la Iglesia posibilitó pensar en la existencia de un puente entre el catolicismo y la izquierda en Colombia, abriéndose al diálogo con visiones de mundo que tradicionalmente había rechazado. Con ello se fue cerrando la brecha entre el catolicismo y la orientación ideológica política de izquierda en el país, permitiendo pensar en la posibilidad de ser católico y de izquierda en el contexto político Colombiano.

(Table 1) Oxygen isotopes in minerals at DSDP Hole 83-504B basalts

The D/H, 18O/16O and 87Sr/86Sr ratios of the basaltic basement from the Leg 83 section of DSDP Hole 504B show that in that area the oceanic crust has experienced intensive but not pervasive alteration. Isotope ratios of the basalts are very heterogeneous because of an input of oxygen, hydrogen, and strontium from seawater. The hydrogen isotopic composition of many samples displays the complete thermal history of the water-rock interactions. High-temperature mineral formations (actinolites, epidotes, and chlorites) were overgrown by a mineralization at lower temperatures (mixedlayer smectites, iddingsites, and smectites) during successive stages of cooling of the oceanic crust by cold seawater. From 87Sr/86Sr data bulk water/rock ratios up to 5:1 have been calculated. There is evidence that some primary minerals like high-An plagioclases contain oxygen from altered basalts. We have discussed the probability that there existed a seawater/crust interface, now at a depth of 620 m sub-basement, during the high-temperature water/rock interactions. This interface was covered during later magmatism by thick flows, pillow lavas, and intrusives.

Modelling Wages and Prices in Australia

This paper estimates a simultaneous-equation model of wages and prices for Australia, underpinned by a competing claims framework of imperfect competition. Two separate co-integrating relationships for wages and prices are identified by imposing the economic hypotheses implied by the theory. The steady-state relationships for wages and prices are then embedded in a parsimonious, dynamic wage-price model. The final model is both simple and parsimonious and able to describe the process of wage and price inflation in Australia

A free weekly iron-folic acid supplementation and regular deworming program is associated with improved hemoglobin and iron status indicators in Vietnamese women

Background Anemia due to iron deficiency is recognized as one of the major nutritional deficiencies in women and children in developing countries. Daily iron supplementation for pregnant women is recommended in many countries although there are few reports of these programs working efficiently or effectively. Weekly iron-folic acid supplementation (WIFS) and regular deworming treatment is recommended for non-pregnant women living in areas with high rates of anemia. Following a baseline survey to assess the prevalence of anemia, iron deficiency and soil transmitted helminth infections, we implemented a program to make WIFS and regular deworming treatment freely and universally available for all women of reproductive age in two districts of a province in northern Vietnam over a 12 month period. The impact of the program at the population level was assessed in terms of: i) change in mean hemoglobin and iron status indicators, and ii) change in the prevalence of anemia, iron deficiency and hookworm infections. Method Distribution of WIFS and deworming were integrated with routine health services and made available to 52,000 women. Demographic data and blood and stool samples were collected in baseline, and three and 12-month post-implementation surveys using a population-based, stratified multi-stage cluster sampling design. Results The mean Hb increased by 9.6 g/L (95% CI, 5.7, 13.5, p < 0.001) during the study period. Anemia (Hb<120 g/L) was present in 131/349 (37.5%, 95% CI 31.3, 44.8) subjects at baseline, and in 70/363 (19.3%, 95% CI 14.0, 24.6) after twelve months. Iron deficiency reduced from 75/329 (22.8%, 95% CI 16.9, 28.6) to 33/353 (9.3%, 95% CI 5.7, 13.0) by the 12-mnth survey, and hookworm infection from 279/366 (76.2%,, 95% CI 68.6, 83.8) to 66/287 (23.0%, 95% CI 17.5, 28.5) over the same period. Conclusion A free, universal WIFS program with regular deworming was associated with reduced prevalence and severity of anemia, iron deficiency and ho

Is the mineral borickyite (Ca,Mg)(Fe3+,Al)4(PO4,SO4,CO3)(OH)8•3-7.5H2O the same as delvauxite CaFe3+4(PO4,SO4)2(OH)8•4-6H2O?

The two minerals borickyite and delvauxite CaFe3+4(PO4,SO4)2(OH)8•4-6H2O have the same formula. Are the minerals identical or different? The minerals borickyite and delvauxite have been characterised by Raman spectroscopy. The minerals are related to the minerals diadochite and destinezite. Both minerals are amorphous. Delvauxite appears to vary in crystallinity from amorphous to semi-crystalline. The minerals are often X-ray non-diffracting. The minerals are found in soils and may be described as ‘colloidal’ minerals. Vibrational spectroscopy enables an assessment of the molecular structure of borickyite and delvauxite. Bands are assigned to phosphate and sulphate stretching and bending modes. Multiple water bending and stretching modes imply that non-equivalent water molecules in the structure exist with different hydrogen bond strengths. The two minerals show differing spectra and must be considered as different minerals.

Grenada, Education and Revolution, 1979-83

Grenada’s New Jewel Movement, led by Maurice Bishop, was the first indigenous political grouping in the history of the English-speaking Caribbean to overthrow an existing government by armed force. Yet most of the four and a half years of the Revolution (1979-83) were characterized by considerable popular support for the new People’s Revolutionary Government before it came to it’s tragic, unexpected and shocking end in October 1983. Social, economic and political change seems possible in the 1970s and ‘80s. People in newly decolonizing countries were encouraged by the beginnings of the Non-Aligned Movement of Third World nations demanding new international economic order that would win them some economic justice after the ravages of colonialism. People also saw that some radical regimes, such as that led by Michael Manley in Jamaica and the Sandinistas in Nicaragua, were articulating and implementing basic rights that held the promise of countering the social and political oppression that they had endured throughout the centuries of colonial history. A majority of Grenadians committed themselves to fighting by the side of the People’s Revolutionary Government for such new goals. This chapter will analyse how the Grenada Revolution reconceptualised the education, planned new goals, and implemented bold new educational policies. It will discuss the extent to which the government and people were able to reshape education as a tool for national reconstruction and the raising of national consciousness.

Frequency of convergence and accommodative disorders in a clinical population of Mashhad, Iran

Purpose To investigate the frequency of convergence and accommodation anomalies in an optometric clinical setting in Mashhad, Iran, and to determine tests with highest accuracy in diagnosing these anomalies. Methods From 261 patients who came to the optometric clinics of Mashhad University of Medical Sciences during a month, 83 of them were included in the study based on the inclusion criteria. Near point of convergence (NPC), near and distance heterophoria, monocular and binocular accommodative facility (MAF and BAF, respectively), lag of accommodation, positive and negative fusional vergences (PFV and NFV, respectively), AC/A ratio, relative accommodation, and amplitude of accommodation (AA) were measured to diagnose the convergence and accommodation anomalies. The results were also compared between symptomatic and asymptomatic patients. The accuracy of these tests was explored using sensitivity (S), specificity (Sp), and positive and negative likelihood ratios (LR+, LR−). Results Mean age of the patients was 21.3 ± 3.5 years and 14.5% of them had specific binocular and accommodative symptoms. Convergence and accommodative anomalies were found in 19.3% of the patients; accommodative excess (4.8%) and convergence insufficiency (3.6%) were the most common accommodative and convergence disorders, respectively. Symptomatic patients showed lower values for BAF (p = .003), MAF (p = .001), as well as AA (p = .001) compared with asymptomatic patients. Moreover, BAF (S = 75%, Sp = 62%) and MAF (S = 62%, Sp = 89%) were the most accurate tests for detecting accommodative and convergence disorders in terms of both sensitivity and specificity. Conclusions Convergence and accommodative anomalies are the most common binocular disorders in optometric patients. Including tests of monocular and binocular accommodative facility in routine eye examinations as accurate tests to diagnose these anomalies requires further investigation.

Roomalaista oikeutta kreikaksi 500-luvun Palestiinassa : Eräitä lakitermejä papyruksessa P. Petra inv. 83

Tutkimuksen tarkoituksena on analysoida eräitä lakitermejä, jotka esiintyvät papyruksessa P. Petra inv. 83. Kyseinen dokumentti, joka sisältää sopimuksen kahden naapuruksen välisen kiistan lopettamiseksi, ajoittuu todennäköisesti vuodelle 574 jKr. ja se kuuluu Jordanian Petrasta vuonna 1993 löydettyyn hiiltyneeseen papyrusarkistoon. Papyrus on tällä hetkellä vielä julkaisematon, ja tämä työ on osa siihen liittyvää perustutkimusta, jonka tarkoituksena on toisaalta selittää tekstin itsensä sisältö, toisaalta arvioida sen antaman informaation merkitystä laajemmassa historiallisessa kontekstissa. Papyrus on kirjoitettu kreikaksi, Bysantin eli Itä-Rooman valtakunnan virallisella kielellä, mutta itse lakitermeistä suurin osa liittyy alun perin latinan kielellä luotuun roomalaiseen oikeuteen. Paikallinen väestö puolestaan oli seemiläistä alkuperää, jolla ei ainoastaan ollut oma kieli, vaan jolla oli ollut ennen valtakuntaan liittämistä omat oikeustraditionsakin. Niinpä papyruksessa esiintyvien termien tutkimuksen kautta nousevat esille monenlaiset laajemmatkin kysymyksenasettelut. Lakitermejä analysoidaan pääasiassa kolmesta näkökulmasta. Ensisijaisena pyrkimyksenä on selvittää niiden tarkka merkitys asiayhteydessään, joka papyruksen fragmentaarisuuden vuoksi ei ole etukäteen selvä, ja siten edistää tekstissä puheena olevien asianhaarojen ymmärtämistä. Toiseksi termien käyttöä koskevat tulokset suhteutetaan yleiseen oikeushistoriaan ja pyritään arvioimaan niiden merkitystä Petrassa käytössä olleen oikeusjärjestelmän kannalta. Kolmas näkökulma on kielitieteellinen, sillä termien käyttö papyruksessa on nähtävä osana laajempaa kehitystä, jossa roomalaisen oikeuden vähittäinen muuttuminen bysanttilaiseksi johti kielten vaihtumiseen ja koko juridisen käsitteistön siirtymiseen latinasta kreikkaan. Siksi tässä työssä käytetään itse papyruksen analyysin lisäksi laajaa vertailumateriaalia, joka koostuu ennen kaikkea roomalaisesta ja bysanttilaisesta lakikirjallisuudesta sekä dokumentaarisesta lähdeaineistosta, etenkin egyptiläisistä papyruksista. Niin tässä papyruksessa kuin muissakin kreikankielisissä lähteissä esiintyvät roomalaiseen oikeuteen liittyvät termit voidaan jaotella suoriin lainoihin, käännöslainoihin sekä komparaatiolainoihin. Jälkimmäisillä tarkoitetaan kreikan kielessä jo aiemmin käytössä olleita termejä, jotka eivät sananmukaiselta merkitykseltään vastaa latinalaisia, mutta joita alettiin käyttää jonkin latinalaisen termin vastineina. Tutkimus tekee selväksi, että olipa kyse mistä lainakategoriasta tahansa, lakitermien siirtyessä kielestä toiseen tapahtui yleensä semanttisia muutoksia eikä termejä aina käytetty samalla tavalla kuin alkukielessä. Merkityskenttä saattoi esimerkiksi supistua taikka laajentua tai sanalle saattoi kehittyä lainautumisen jälkeen täysin uusiakin merkityksiä. Oikeushistorian suhteen on huomioitava ero virallisten säännösten ja provinsseissa noudatettujen käytäntöjen välillä. Kaiken kaikkaan Petra näyttää kuitenkin olleen kiinteä osa Bysantin valtakuntaa, jonka lakeja ainakin pääpiirteissään noudatettiin. Kaikkien termien käytötavat eivät tosin ole johdettavissa suoraan virallisiin lakikorpuksiin, mutta ne eivät myöskään sodi niitä vastaan. Roomalaisen oikeuden tuntemus näyttää olleen Petrassa jopa parempaa kuin esimerkiksi Egyptissä. Mitä tulee papyruksessa puheena oleviin konkreettisiin asianhaaroihin, termien merkityksen ymmärtäminen selventää joidenkin aspektien pääpiirteitä, kun taas yksityskohdat jäävät tekstin fragmentaarisuuden takia useimmiten epäselviksi.

Bysanttilaisten ja Akhaian ruhtinaskunnan väliset sotatoimet vuosina 1259-83 : Tapaustutkimus myöhäis-bysanttilaisesta sodankäynnistä

In my master thesis I analyse Byzantine warfare in the late period of the empire. I use military operations between Byzantines and crusader Principality of Achaia (1259–83) as a case study. Byzantine strategy was based (in “oriental manner”) on using ambushes, diplomacy, surprise attacks, deception etc. Open field battles that were risky in comparison with their benefits were usually avoided, but the Byzantines were sometimes forced to seek open encounter because their limited ability to keep strong armies in field for long periods of time. Foreign mercenaries had important place in Byzantine armies and they could simply change sides if their paymasters ran out of resources. The use of mercenaries with short contracts made it possible that the composition of an army was flexible but on the other hand heterogeneous – in result Byzantine armies were sometimes ineffective and prone to confusion. In open field battles Byzantines used formation that was made out from several lines placed one after another. This formation was especially suitable for cavalry battles. Byzantines might have also used other kinds of formations. The Byzantines were not considered equal to Latins in close combat. West-Europeans saw mainly horse archers and Latin mercenaries on Byzantine service as threats to themselves in battle. The legitimacy of rulers surrounding the Aegean sea was weak and in many cases political intrigues and personal relationships can have resolved the battles. Especially in sieges the loyalty of population was decisive. In sieges the Byzantines used plenty of siege machines and archers. This made fast conquests possible, but it was expensive. The Byzantines protected their frontiers by building castles. Military operations against the Principality of Achaia were mostly small scale raids following an intensive beginning. Byzantine raids were mostly made by privateers and mountaineers. This does not fit to the traditional picture that warfare belonged to the imperial professional army. It’s unlikely that military operations in war against the Principality of Achaia caused great demographic or economic catastrophe and some regions in the warzone might even have flourished. On the other hand people started to concentrate into villages which (with growing risks for trade) probably caused disturbance in economic development and in result birth rates might have decreased. Both sides of war sought to exchange their prisoners of war. These were treated according to conventional manners that were accepted by both sides. It was possible to sell prisoners, especially women and children, to slavery, but the scale of this trade does not seem to be great in military operations treated in this theses.
