A rebuttal to Ahiakpor's criticisms and a reflection on the historical craft

I want to thank Professor Ahiakpor for engaging with my work. A historian rarely experiences the “subjects” of his research talking back to him because we mainly deal with the archival traces that they left. Whereas my first book, The Ideological Scramble for Africa, focused on the 1950s and 1960s, my article in the previous issue of the Southern Journal for Contemporary History is my first foray into the 1970s and 1980s. As a result, I now have the opportunity to enter into a dialogue with Professor Ahiakpor, who claims my article, “contains several misrepresentations and false claims”. He disagrees with my interpretation of people’s motivations as well as my thesis that many classical economists in Ghana supported the “anticolonial capitalism” project: the embrace of the market to further the political project of liberation in the 1970s and 1980s

A practical application of text mining to literature on cognitive rehabilitation and enhancement through neurostimulation

The exponential growth in publications represents a major challenge for researchers. Many scientific domains, including neuroscience, are not yet fully engaged in exploiting large bodies of publications. In this paper, we promote the idea to partially automate the processing of scientific documents, specifically using text mining (TM), to efficiently review big corpora of publications. The “cognitive advantage” given by TM is mainly related to the automatic extraction of relevant trends from corpora of literature, otherwise impossible to analyze in short periods of time. Specifically, the benefits of TM are increased speed, quality and reproducibility of text processing, boosted by rapid updates of the results. First, we selected a set of TM-tools that allow user-friendly approaches of the scientific literature, and which could serve as a guide for researchers willing to incorporate TM in their work. Second, we used these TM-tools to obtain basic insights into the relevant literature on cognitive rehabilitation (CR) and cognitive enhancement (CE) using transcranial magnetic stimulation (TMS). TM readily extracted the diversity of TMS applications in CR and CE from vast corpora of publications, automatically retrieving trends already described in published reviews. TMS emerged as one of the important non-invasive tools that can both improve cognitive and motor functions in numerous neurological diseases and induce modulations/enhancements of many fundamental brain functions. TM also revealed trends in big corpora of publications by extracting occurrence frequency and relationships of particular subtopics. Moreover, we showed that CR and CE share research topics, both aiming to increase the brain's capacity to process information, thus supporting their integration in a larger perspective. Methodologically, despite limitations of a simple user-friendly approach, TM served well the reviewing process

Fan texture of the compound Ba3Co2Fe244O41 pre-aligned in a magnetic field

Samples of the ferrimagnetic material Ba3Co2Fe24O41, pre-aligned in a magnetic field and sintered at various temps., have been examd. for preferred orientation. Schulz's reflection technique and the standardizing method of Holland were used to det. quant. pole figures of several lattice planes. The texture bears a close resemblance to a \"fan texture Degs in which the crystallites have their basal planes parallel to a preferred direction. The sharpness of the texture increases with increasing sintering temp. At 1320 Deg an exaggerated grain growth takes place. Inhomogeneity of the magnetic field throughout the sample results in local differences in orientation. [on SciFinder (R)

Entropy and Correlations in Lattice Gas Automata without Detailed Balance

We consider lattice gas automata where the lack of semi-detailed balance results from node occupation redistribution ruled by distant configurations; such models with nonlocal interactions are interesting because they exhibit non-ideal gas properties and can undergo phase transitions. For this class of automata, mean-field theory provides a correct evaluation of properties such as compressibility and viscosity (away from the phase transition), despite the fact that no H-theorem strictly holds. We introduce the notion of locality - necessary to define quantities accessible to measurements - by treating the coupling between nonlocal bits as a perturbation. Then if we define operationally ``local'' states of the automaton - whether the system is in a homogeneous or in an inhomogeneous state - we can compute an estimator of the entropy and measure the local channel occupation correlations. These considerations are applied to a simple model with nonlocal interactions.Comment: 13 pages, LaTeX, 5 PostScript figures, uses psfig. Submitted to Int. J. Mod. Phys.

Transgenic mice expressing constitutive active MAPKAPK5 display gender-dependent differences in exploration and activity

<p>Abstract</p> <p>Background</p> <p>The mitogen-activated protein kinases, MAPKs for short, constitute cascades of signalling pathways involved in the regulation of several cellular processes that include cell proliferation, differentiation and motility. They also intervene in neurological processes like fear conditioning and memory. Since little remains known about the MAPK-Activated Protein Kinase, MAPKAPK5, we constructed the first MAPKAPK knockin mouse model, using a constitutive active variant of MAPKAPK5 and analyzed the resulting mice for changes in anxiety-related behaviour.</p> <p>Methods</p> <p>We performed primary SHIRPA observations during background breeding into the C57BL/6 background and assessed the behaviour of the background-bred animals on the elevated plus maze and in the light-dark test. Our results were analyzed using Chi-square tests and homo- and heteroscedatic T-tests.</p> <p>Results</p> <p>Female transgenic mice displayed increased amounts of head dips and open arm time on the maze, compared to littermate controls. In addition, they also explored further into the open arm on the elevated plus maze and were less active in the closed arm compared to littermate controls. Male transgenic mice displayed no differences in anxiety, but their locomotor activity increased compared to non-transgenic littermates.</p> <p>Conclusion</p> <p>Our results revealed anxiety-related traits and locomotor differences between transgenic mice expressing constitutive active MAPKAPK5 and control littermates.</p

Anticolonial Capitalism: How Ghana came to embrace Market-Led Development Theory (the 1970s-1990s)

The shift from the Keynesian welfare state to the neoliberal market society is understood to have taken place in the Global North between, the 1970s and the 1990s while the Global South was forced to accept the economic liberalization and austerity, as devised by the World Bank and the International Monetary Fund (IMF). This article redresses this imbalance by studying how African economists, sociologists and politicians in Ghana co-wrote neoliberal development theory, co-created an anticolonial definition of capitalism and shaped Ghanaian diplomacy which sought to create a different kind of economic order. When Jerry Rawlings staged his final coup in 1981, he transformed from someone with vague socialist sympathies into a leader who spearheaded market reform and applied for loans from the World Bank and the IMF. Rather than a cynical move to retain power, this article argues he and his advisers were part of a broader intellectual shift in which African Socialism, dependency theory and Marxism were rejected as ineffective. Instead, the market came to be wielded as a new weapon for anticolonial liberation in the 1970s and 1980s. Principal thinkers with a connection to Rawlings were Jonathan H. Frimpong-Ansah, Kwesi Botchwey and James C.W. Ahiakpor. They are analysed in this article which explores the intellectual foundation of a political regime that fundamentally changed Ghana in the 1980s
