Convex Phillips Curve Explaining Openness and Inflation Nexus  [PDF]
S. Ali Shah Syed, Helène Syed Zwick
Theoretical Economics Letters (TEL) , 2015, DOI: 10.4236/tel.2015.56086
Abstract: We study the theoretical nexus between inflation and trade openness in the presence of a non-linear Phillips curve. Phillips curve explains the inverse relationship between unemployment and inflation; however, the open economy macroeconomic models usually propose that the slope of the trade-off should be related to the extent of trade openness. The role of openness as a check on inflation has recently attracted attention of many [1]. The parallelism between the recent globalization wave and the fall in inflation has led to a perception that the determinants of the slowdown in inflation were not only the domestic ones but could partly be due to increased trade openness. This study describes this relationship considering a non-linear Phillips curve. Using the conventional Phillips curve approximated by Cobb-Douglas model we confirm the earlier observations regarding the existence of a significant impact of openness on inflation. The interesting contribution of this study is not only to establish the trade-openness and inflation nexus but also to identify the relevant channels through which openness impacts inflation. Our model predicts that in the current scenario of increased openness a non-linear symmetric loss function may still prevail, but for the policy purposes it necessitates to consider domestic and foreign propensities to import and the exchange rate sensitivity to inflation. In addition, the integration of the international markets would result into an even more important role of exchange rate dynamics as a response to the rising international trade. We find that in the presence of a convex Phillips curve any upward variation in the foreigners’ propensity to import would place a downward pressure on domestic inflation, provided that the current and the lagged rate of unemployment are less than minimum unemployment rate. Our model, while assessing the short run dynamics, also suggests that increased openness results into a complex divide among different economies, due to their sizes and structures. Investigating such a relationship as an extension of this study for different economic groups could reveal further interesting facts.
Oil Price Shocks and the US Stock Market: Slope Heterogeneity Analysis  [PDF]
Sarfaraz Ali Shah Syed, Hélène Syed Zwick
Theoretical Economics Letters (TEL) , 2016, DOI: 10.4236/tel.2016.63055
Abstract: This study investigates the oil and stock prices nexus in the US economy over the period 1980-2016. Using breakpoint regression technique, our findings are twofold: 1) we confirm the existence of the nexus as established in the existing literature on the subject; 2) while the relationship between the oil and stock prices remains intact, the slope changes over time, thus identifying a non-linear relationship.
Conference of the Liber Groupe des Cartothecaires, Paris 29th August-2nd September 2006
Helène Richard
Liber Quarterly : The Journal of European Research Libraries , 2007,
Abstract: Following on from Copenhagen (2000), Helsinki (2002) and Cambridge (2004), the meeting of the "Groupe des Cartothécaires" took place in Paris from the 29th of August to the 2nd of September 2006. It was hosted by the Bibliothèque nationale de France ( BnF), with the support of Institut Géographique National ( IGN), Service Historique de la Défense ( SHD), Archives nationales and the Library of the Chateau de Chantilly. The Conference was organised by the Comité Fran ais de Cartographie (CFC). A committee was set up within the CFC, which organised the scientific program and participated in the general organisation.
Aksumstelen. Et monuments skiftende betydninger
Helène Whittaker
Nordlit : Tidsskrift i litteratur og kultur , 2005,
Abstract: This article deals with the various meanings associated with the Aksum stela which was taken from Ethiopia to Rome in 1937 and returned in 2005. It discusses its original meaning as a burial monument, its role in Mussolini’s propaganda, and the new meaning it has acquired after having been returned to Ethiopia and Aksum.

Game-Boards and Gaming-Pieces in Funerary Contexts in the Northern European Iron Age
Helène Whittaker
Nordlit : Tidsskrift i litteratur og kultur , 2006,
Abstract: Gaming-pieces, dice, and game-boards are found in connection with burials at various times and places from an early date. For instance, in Egypt there was a clear association between the game known as Senet and burials from the time of the Old Kingdom (Pusch 1979; Piccione 1984). Dice are not uncommonly found in Greek, Etruscan, and Roman tombs (Vermeule 1979, 80; Pallottino 1955, fig. 95; Egidi 1983). It can reasonably be assumed that the playing of board games was seen as a pleasurable pastime which one could hopefully continue to pursue in the Afterlife. However, it can in some cases be argued that gaming equipment in burial contexts was related to the social status of the deceased or to religious beliefs and therefore had a more complex significance. In this article I will look at the occurrence of gaming-pieces, dice, and game-boards in burials in the northern European Iron Age.

Durability of concrete mixed with fine recycled aggregates
Salomon Levy,Paulo Helène
Exacta , 2007,
Abstract: In this paper, an analysis was conducted on the influence of the use of 20%, 50% and 100% contents of two types of fine recycled aggregates (from demolish concrete and from old masonry) on the following properties of concrete: water absorption by immersion, pore volume, carbonation and resistivity. This analysis was not restricted to compare mixtures from a table of results. All the analysis was based on concrete family behavior. The Mix Design Nomograms (MDN) was made for concrete families: one as reference and six others with different recycled contents to replace the natural fine aggregate. The MDN obtained for the properties studied permitted compare class 20MPa, 30MPa and 40MPa concretes. The results obtained indicate that the carbonation depth reached a minimum and the resistivity reached a maximum when 50% contents of fine recycled masonry aggregates were used. However, this tendency was not repeated for pore volume and water absorption. Thus, it should conclude that the durability like a carbonation and resistivity are physical-chemical phenomena that, in this case, were inversely related to water absorption and volume of pores.
The impact of teachers' limited english proficiency on english second language learners in South African schools
Norma Nel,Heléne Müller
South African Journal of Education , 2010,
Abstract: The importance of the role of language in teacher education programmes and in children's learning is crucial. This study focuses on the use of English as the language of learning and teaching and its impact on the language development of English second language (ESL) student teachers and ESL learners. Against the background of major theories in second language (L2) acquisition and learning, this topic is contextualized within the South African education system. An empirical inquiry was carried out in which portfolios (evidence of practical teaching including lesson plans and learners' work) submitted by final year student teachers enrolled at a large distance teaching university for the Advanced Certificate in Education: Inclusive Education were scrutinised. A comparison of teacher and learner written errors was made. Based on the findings, a questionnaire was designed to determine the extent of the impact of teachers' limited English proficiency on learners' English proficiency. The findings of the questionnaire responses are presented. Recommendations are made on how student teachers can improve their teaching practice to ensure quality ESL teacher input and ESL learner performance.
