We present a review of the historical evolution of software engineering, intertwining it with the history of knowledge engineering because “those who cannot remember the past are condemned to repeat it.” This retrospective represents a further step forward to understanding the current state of both types of engineerings; history has also positive experiences; some of them we would like to remember and to repeat. Two types of engineerings had parallel and divergent evolutions but following a similar pattern. We also define a set of milestones that represent a convergence or divergence of the software development methodologies. These milestones do not appear at the same time in software engineering and knowledge engineering, so lessons learned in one discipline can help in the evolution of the other one.

Denna tvärvetenskapliga studie kontextualiserar den skönlitterära framställningen av hungersnöden i Irland i mitten av 1800-talet i förhållande till tre olika faser av irländsk historieskrivning ‒ den nationalistiska, den revisionistiska, och den postrevisionistiska ‒ med syfte att granska i vilken mån prosafiktionen antingen återspeglar eller motsäger historikernas tolkningar. År 1845 drabbades landet av en dittills okänd potatispest som förstörde skörden helt eller delvis under de följande fem åren. Missväxten ledde till utbredd svält och epidemiska sjukdomar som dödade åtminstone en miljon människor, medan ytterligare en och en halv miljon flydde, huvudsakligen till Förenta Staterna, England, och Kanada. I sina försök att hitta en rationell förklaring till hur potatispesten kunde utvecklas till den värsta svältkatastrofen i Europa under modern tid, har historiker påvisat ett antal bidragande faktorer, till exempel överbefolkning, de fattigaste jordlösa småbrukarnas och lantarbetarnas beroende av potatisen som sitt baslivsmedel, underutveckling inom jordbruket, det rådande jordegendomssystemet, och den dåvarande brittiska regeringens misslyckande att tillhandahålla effektiv och tillräcklig nödhjälp. Historiska förklaringar är naturligtvis nödvändiga för att vi skall kunna bilda oss en uppfattning om hungersnödens orsaker och konsekvenser, men svårigheten med att skildra offrens situation i en historiografisk analys baserad på fakta är uppenbar då deras egna vittnesmål till största delen saknas i källmaterialet. Följaktligen finns det en risk att historieskrivningen förmörkar det som onekligen var centrala realiteter för de värst drabbade, nämligen svält, vräkning, sjukdom och död. Här kan skönlitteraturen bidra till att komplettera historien. Genom att fokusera på ett specifikt (fiktivt) samhälle och dess (fiktiva) individer, kan skönlitterära verk ge en inblick i hur hungersnöden inverkade på olika samhällsskikt, vad människorna gjorde för att överleva, hur nöden och fasorna påverkade deras psyke, och vad eller vem de höll ansvariga för katastrofen. Å andra sidan kan denna fokusering innebära att författaren misslyckas med att ge en helhetsbild av hungersnödens enorma omfattning och att redogöra för alla faktorer som orsakade och förlängde den. Paul Ricoeurs teori om samspelet mellan historia och fiktion (the interweaving of history and fiction) är därför ett nyckelbegrepp för att bättre förstå denna traumatiska period i Irlands historia. Avhandlingen omfattar en textanalytisk, komparativ kritik av ett antal historiska och skönlitterära verk. Genom närläsning av dessa texter granskar jag vilka aspekter av hungersnöden (politiska, ekonomiska, sociala) de olika författarna valt att behandla, och på vilket sätt, samt hur deras synvinklar har format tolkningarna i sin helhet. I detta sammanhang tar jag också upp skillnaderna mella fakta och fiktion, och speciellt de etiska problem som är förknippade med skildringen av traumatiska händelser och mänskligt lidande. Samtidigt undersöker jag, med hänvisning till Roger D. Sells kommunikationsteori, huruvida vissa författare anslår en påstridig ton i sina verk och hur detta påverkar dialogen mellan författare och läsare. Med utgångspunkt i Ricoeurs teori argumenterar jag för att historia och fiktion inte bör ses som ömsesidigt antitetiska diskurser i skildringen och tolkningen av det förflutna, och att skönlitteraturen genom fokuseringen på offren, som ofta tenderar att reduceras till statistik i historieskrivningen, kan förmedla en bättre förståelse och en djupare känsla för den mänskliga dimensionen av den tragedi som utspelades under hungeråren.

Dehram group includes Faraghan, Dalan and Kangan formations. Kangan formation ages lower terias. That is one of the important reservoir rocks of southern Iran and Persian Gulf. In this research Kangan formation is studied in two A and B wells. Based on 75 studies on thin section, four carbonate litho acies association A, B, C, D with 12 subfacies are identified. A lithofacies association includes 4 subfacies: A1, A2, A3 and A4. B lithofacies association consists of 3 subfacies: B1, B2 and B3. C lithofacies association consists of 3 subfacies: C1, C2, C3 and D lithofacies association includes 2 subfacies: D1 and D2. On the base of studies lithofacies association of Kangan formations are formed in 3 environments of: Tidal Flat, Lagoon and Barrier Shore Complex in a Carbonated Platform Ramp type. Diagenetic processes have effected this formation. The most important Diagenetic processes are: Cementation, Anhydritization, Micrization, Neomorphism, Bioturbation, Dissolution, Compaction, Dolomitization and Porosity. Sequence staratigraphy studies were performed base on the vertical and horizontal relationship of lithofacies association and well logging in gamma ray and sonic type that causes the identification of two sedimentary sequences: First sedimentary sequence includes: Transgressive System Tract (TST) and High Stand System Tract (HST). The lower boundary of this sequence is in Sequence Boundary 1 (SB1) which shows unconformities of Dalan and Kangan that are Permian-terias unconformities. The upper boundary is in Sequence Boundary 2 (SB2) type that is identified by carbonate facies associated by anhydrite nodular. Second sedimentary sequence includes: TST and HST. Lower and upper boundaries of these sequences are both in SB2 type. The lower and upper boundary is made of carbonate facies with anhydrite nodular.

Since the beginning of the Haitian theatrical tradition there has been an ineluctable dedication to the representation of Haitian history on stage. Given the rich theatrical archive about Haiti throughout the world, this study considers operas and plays written solely by Haitian playwrights. By delving into the works of Juste Chanlatte, Massillon Coicou, and Vendenesse Ducasse this study proposes a re-reading of Haitian theater that considers the stage as an innovative site for contesting negative and clichéd representations of the Haitian Revolution and its revolutionary leadership. A genre long mired in accusations of mimicking European literary forms, this study proposes a reevaluation of Haitian theater and its literary origins.

This thesis investigates how the strong verb system inherited from Old English evolved in the regional dialects of Middle English (ca. 1100-1500). Old English texts preserve a relatively complex system of strong verbs, in which traditionally seven different ablaut classes are distinguished. This system becomes seriously disrupted from the Late Old English and Early Middle English periods onwards. As a result, many strong verbs die out, or have their ablaut patterns affected by sound change and morphological analogy, or transfer to the weak conjugation. In my thesis, I study the beginnings of two of these developments in two strong verb classes to find out what the evidence from Middle English regional dialects can tell us about their origins and diffusion. Chapter 2 concentrates on the strong-to-weak shift in Class III verbs, and investigates to what extent strong, mixed and weak past tense and participle forms vary in Middle English dialects, and whether the variation is more pronounced in the paradigms of specific verbs or sub-classes. Chapter 3 analyses the regional distribution of ablaut levelling in strong Class IV verbs throughout the Middle English period. The Class III and IV data for the Early Middle English period are drawn from A Linguistic Atlas of Early Middle English, and the data for the Late Middle English period from a sub-corpus of files from The Penn-Helsinki Parsed Corpus of Middle English and The Middle English Grammar Corpus. Furthermore, The English Dialect Dictionary and Grammar are consulted as an additional reference point to find out to what extent the Middle English developments are reflected in Late Modern English dialects. Finally, referring to modern insights into language variation and change and linguistic interference, Chapter 4 discusses to what extent intra- and extra-linguistc factors, such as token and type frequency, stem structure and language contact, might correlate with the strong-to-weak shift and ablaut levelling in Class III and IV verbs in the Middle English period. The thesis is accompanied by six appendices that contain further information about my distinction of Middle English dialect areas (Appendix A), historical Class III and IV verbs (B and C) and the text samples and linguistic data from the Middle English text corpora (D, E and F).

Morocco was the last North African country in which a Pasteur institute was created, nearly two decades later than in Tunisia and Algeria. In fact, two institutes were opened, the first in Tangier in 1913 and the second in Casablanca in 1932. This duplication, far from being a measure of success, was the material expression of the troubles Pastorians had experienced in getting a solid foothold in the country since the late 19th century. These problems partly derived from the pre-existence of a modest Spanish-Moroccan bacteriological tradition, developed since the late 1880s within the framework of the Sanitary Council and Hygiene Commission of Tangier, and partly from the uncoordinated nature of the initiatives launched from Paris and Algiers. Although a Pasteur Institute was finally established, with Paul Remlinger as director, the failure of France to impose its colonial rule over the whole country, symbolized by the establishment of an international regime in Tangier, resulted in the creation of a second centre in Casablanca. While elucidating many hitherto unclear facts about the entangled origins of both institutes, the author points to the solidity of the previously independent Moroccan state as a major factor behind the troubled translation of Pastorianism to Morocco. Systematically dismissed or downplayed by colonial and postcolonial historiography, this solidity disrupted the French takeover of the country and therefore Pastorian expectations.

Question: How can the coexistence of savanna and forest in Amazonian areas with relatively uniform climates be explained? Location: Eastern Marajo Island, northeast Amazonia, Brazil. Methods: The study integrated floristic analysis, terrain morphology, sedimentology and delta(13)C of soil organic matter. Floristic analysis involved rapid ecological assessment of 33 sites, determination of occurrence, specific richness, hierarchical distribution and matrix of floristic similarity between paired vegetation types. Terrain characterization was based on analysis of Landsat images using 4(R), 5(G) and 7(B) composition and digital elevation model (DEM). Sedimentology involved field descriptions of surface and core sediments. Finally, radiocarbon dating and analysis of delta(13)C of soil profile organic matter and natural ecotone forest-savanna was undertaken. Results: Slight tectonic subsidence in eastern Marajo Island favours seasonal flooding, making it unsuitable for forest growth. However, this area displays slightly convex-up, sinuous morphologies related to paleochannels, covered by forest. Terra-firme lowland forests are expanding from west to east, preferentially occupying paleochannels and replacing savanna. Slack, running water during channel abandonment leads to disappearance of varzea/gallery forest at channel margins. Long-abandoned channels sustain continuous terra-firme forests, because of longer times for more species to establish. Recently abandoned channels have had less time to become sites for widespread tree development, and are either not vegetated or covered by savanna. Conclusion: Landforms in eastern Marajo Island reflect changes in the physical environment due to reactivation of tectonic faults during the latest Quaternary. This promoted a dynamic history of channel abandonment, which controlled a set of interrelated parameters (soil type, topography, hydrology) that determined species location. Inclusion of a geological perspective for paleoenvironmental reconstruction can increase understanding of plant distribution in Amazonia.

This article intends to contribute to the reflection on the Educational Statistics as being source for the researches on History of Education. The main concern was to reveal the way Educational Statistics related to the period from 1871 to 1931 were produced, in central government. Official reports - from the General Statistics Directory - and Statistics yearbooks released by that department were analyzed and, on this analysis, recommendations and definitions to perform the works were sought. By rending problematic to the documental issues on Educational Statistics and their usual interpretations, the intention was to reduce the ignorance about the origin of the school numbers, which are occasionally used in current researches without the convenient critical exam.

Science education is under revision. Recent changes in society require changes in education to respond to new demands. Scientific literacy can be considered a new goal of science education and the epistemological gap between natural sciences and literacy disciplines must be overcome. The history of science is a possible bridge to link these `two cultures` and to foster an interdisciplinary approach in the classroom. This paper acknowledges Darwin`s legacy and proposes the use of cartoons and narrative expositions to put this interesting chapter of science into its historical context. A five-lesson didactic sequence was developed to tell part of the story of Darwin`s expedition through South America for students from 10 to 12 years of age. Beyond geological and biological perspectives, the inclusion of historical, social and geographical facts demonstrated the beauty and complexity of the findings that Darwin employed to propose the theory of evolution.

The objective of this article is to examine the presence of cinema in World Fairs between the 1893 World`s Columbian Exposition in Chicago and 1939 (the New York World`s Fair). As an integral part of a visual culture constructed by these spaces to celebrate capitalism, the trajectory of cinema is identified with these world fairs due to its ability to entertain and, at the same time, to educate. Cinema was established as a means of mass communication during the First World War and afterwards would participate more actively in the symbolic disputes of a world about to enter the second global conflict. It would reach a broader public, becoming the main `showcase` in which nations projected virtues to be celebrated. The new striking visual spectacle assumed, within this context, greater emphasis through films idealized as true cinematographic monuments.

This article explores human rights and education based on an intervention experience conducted in three schools located in Sao Paulo City, which had as its main goal a substantial reduction in violence (2004-2005). The guideline was that education should be considered a basic human right, taking into consideration the power and authority relations that exist within this institution. What are the problems that we face, nowadays, to consider education as a human right, in the difficult Brazilian history? Is it possible to think about some kind of democratic authority within the school, when our vision of authority is linked to despotic leaders, or even when there is no space for any authority? How does this discussion associate with the violence in our daily life in school? These are some of the questions included in the debate proposed by this article.

Clifford Geertz was best known for his pioneering excursions into symbolic or interpretive anthropology, especially in relation to Indonesia. Less well recognised are his stimulating explorations of the modern economic history of Indonesia. His thinking on the interplay of economics and culture was most fully and vigorously expounded in Agricultural Involution. That book deployed a succinctly packaged past in order to solve a pressing contemporary puzzle, Java's enduring rural poverty and apparent social immobility. Initially greeted with acclaim, later and ironically the book stimulated the deep and multi-layered research that in fact led to the eventual rejection of Geertz's central contentions. But the veracity or otherwise of Geertz's inventive characterisation of Indonesian economic development now seems irrelevant; what is profoundly important is the extraordinary stimulus he gave to a generation of scholars to explore Indonesia's modern economic history with a depth and intensity previously unimaginable.
