At the Edge of the Modern?: Diplomacy, Public Relations, and Media Practices During Houphouët-Boigny\u27s 1962 Visit to the United States

Toward the end of the first decade after the decolonization of most African countries, there emerged a scholarly polemic about the weight of bureaucratic politics in the making of foreign policy in the Third World. A mirror of the reigning modernization paradigm that informed most postwar area studies and social sciences, the discussion unintentionally indexed the narcissism of a hegemonic discourse on political development and statecraft. Graham Allison and Morton Halperin—the original proponents of the bureaucratic model—implied in their largely U.S.-centric model that such a paradigm was not applicable to non-industrialized countries since the newly decolonized countries, for the most part, lacked the institutional/organizational base and political tradition needed to conduct a modern foreign policy. Félix Houphouët- Boigny—leader of the newly independent Ivory Coast—was hardly mentioned in the scholarly debates on the bureaucratic model. Yet one can use the conjuncture of his visit to the United States in May 1962 to explore the arguments developed by the protagonists in the polemic that ensued the publication of the Allison-Halperin theory

An Unconventional Challenge to Apartheid: The Ivorian Dialogue Diplomacy with South Africa, 1960-1978

This article focuses on the dialogue diplomacy that Ivorian President Félix Houphouët-Boigny initiated in the late 1960s to engage apartheid South Africa. Although contemporary observers and subsequent scholars (have) derided the scheme as an act of acquiescence and even betrayal, I argue that Ivory Coast\u27s dialogue diplomacy was neither accommodationist nor dependent on the prodding of neocolonial powers such as France. A Pan-Africanist extension of the home-grown neotraditional practice of Dialogue ivoirienne, the diplomatic initiative never got the backing of other African states. A close analysis of the Ivory Coast\u27s maneuvers in the context of an increasing radicalization of the anti-apartheid movement sheds a new light on the complexity of the transnational politics to defeat apartheid

Featured Piece

This year the General Editors continued the tradition started last year by creating a feature piece to show our appreciation for the History Department. We selected four professors from the faculty to answer a question about history: what figure/event/idea inspires your interest in history? Reading their responses helped give us insight into the thoughts of these brilliant minds and further help us understand their passion for the subject we all share a common love and interest in. We hope that you enjoy reading their responses as much as we did. The four members of the faculty we spoke with are Dr. Abou Bamba, Dr. William Bowman, Dr. David Hadley, and Magdalena Sánchez

Axially magnetized Dark Energy cosmological model

We investigate the behaviour of the skewness parameters for an anisotropic universe in the framework of General Relativity. Non interacting dark energy is considered in presence of electromagnetic field. A time varying deceleration parameter simulated by a hybrid scale factor is considered. The dynamics of the universe is investigated in presence and absence of magnetic field. The equation of state parameter of dark energy evolves within the range predicted by the observations. Magnetic field is observed to have a substantial effect on the cosmic dynamics and the skewness parameters. The models discussed here end in a big rip and become isotropic at finite time.Comment: 9 pages, 13 figures, Version accepted for publication in Mod. Phys. Lett.

Property of the spectrum of large-scale magnetic fields from inflation

The property of the spectrum of large-scale magnetic fields generated due to the breaking of the conformal invariance of the Maxwell theory through some mechanism in inflationary cosmology is studied. It is shown that the spectrum of the generated magnetic fields should not be perfectly scale-invariant but be slightly red so that the amplitude of large-scale magnetic fields can be stronger than $\sim 10^{-12}$G at the present time. This analysis is performed by assuming the absence of amplification due to the late-time action of some dynamo (or similar) mechanism.Comment: 8 pages, no figure; references correcte

Thermal and Non-thermal X-Rays from the LMC Super Bubble 30 Dor C

We report on the discovery of thermal and non-thermal X-rays from the shells of the super bubble (SB) 30 Dor C in the Large Magellanic Cloud (LMC). The X-ray morphology is a nearly circular shell with a radius of about 40 pc, which is bright on the northern and western sides. The spectra of the shells are different from region to region. The southern shell shows clear emission lines, and is well fitted with a model of a thin-thermal plasma (kT = 0.21keV) in non-equilibrium ionization (NEI) plus a power-law component. This thermal plasma is located inside of the H alpha emission, which is the outer edge of the shell of the SB. The northern and western sides of the SB are dim in H alpha emission, but are bright in non-thermal (power-law) X-rays with a photon index of 2.1-2.9. The non-thermal X-ray shell traces the outer boundary of the radio shell. These features of thin-thermal and non-thermal X-rays are similar to those of SN 1006, a prototype of synchrotron X-ray shell, but the non-thermal component of 30 Dor C is about ten-times brighter than that of SN 1006. 30 Dor C is the first candidate of an extragalactic SB, in which energetic electrons are accelerating in the shell. The age is much older than that of SN 1006, and hence the particle acceleration time in this SB may be longer than those in normal shell-like SNRs. We found point-like sources associated with some of tight star clusters. The X-ray luminosity and spectrum are consistent with those of young clusters of massive stars. Point-like sources with non-thermal spectra are also found in the SB. These may be background objects (AGNs) or stellar remnants (neutron stars or black holes).Comment: 11 pages, 6 figures, Accepted for publication in ApJ, the paper with full resolution images in http://www-cr.scphys.kyoto-u.ac.jp/member/bamba/Paper/30DorC.pd

Baryon asymmetry from hypermagnetic helicity in dilaton hypercharge electromagnetism

The generation of the baryon asymmetry of the Universe (BAU) from the hypermagnetic helicity, the physical interpretation of which is given in terms of hypermagnetic knots, is studied in inflationary cosmology, taking into account the breaking of the conformal invariance of hypercharge electromagnetic fields through both a coupling with the dilaton and that with a pseudoscalar field. It is shown that if the electroweak phase transition (EWPT) is strongly first order and the present amplitude of the generated magnetic fields on the horizon scale is sufficiently large, a baryon asymmetry with a sufficient magnitude to account for the observed baryon to entropy ratio can be generated.Comment: 16 pages, 2 figures, a reference added, typos correcte

G\"odel-type universes in f(T) gravity

The issue of causality in $f(T)$ gravity is investigated by examining the possibility of existence of the closed timelike curves in the G\"{o}del-type metric. By assuming a perfect fluid as the matter source, we find that the fluid must have an equation of state parameter greater than minus one in order to allow the G\"{o}del solutions to exist, and furthermore the critical radius $r_c$, beyond which the causality is broken down, is finite and it depends on both matter and gravity. Remarkably, for certain $f(T)$ models, the perfect fluid that allows the G\"{o}del-type solutions can even be normal matter, such as pressureless matter or radiation. However, if the matter source is a special scalar field rather than a perfect fluid, then $r_c\rightarrow\infty$ and the causality violation is thus avoided.Comment: 18 pages, introduction revised, reference adde
