Understanding the vehicle behaviour in the tire saturation region, close to the grip limit, is really important when the safety during vehicle motion is concerned. In case of autonomous vehicle research, usually the so called \"safety-margin\" is defined to describe this limit behaviour. For this, often a simulation environment is used. These environments can over-simplify suspension parameters that leads to inaccurate results, in such conditions. This paper investigates the effect of these parameters, in a given simulation software, to understand if parameter changes, eg.: roll center height, creates the expected changes in vehicle behaviour. This way it is possible to validate, if the chosen environment is \"good enough\" for our safety-margin research in the future.

Development agencies and sympathetic scholars have placed much credence in the view that multiparty systems will produce better economic policies in Africa. In particular, the empowerment of rural majorities that multiparty systems are expected to bring should increase efforts to reverse urban-rural terms of trade. While not disputing the claim that multiparty systems may produce greater accountability of politicians to the interests of farmers where smallholders make up most of the population, this article questions whether there is either a clear or continuous relationship between increasing scope for choice at the ballot box and improving the policy environment for agriculture.

In his novels and essays and most recently in the pages of The New York Times, Nigerian author Chinua Achebe has repeatedly claimed that the “trouble with Nigeria” lies with its leaders (1982, 1993)—and few of those who followed the pronouncements of General Babangida would say that the actions of the Nigerian head of state were without import for the political future of the country. Achebe finds an intellectual ally in social scientist Giuseppe de Palma (1992), who argues that the actions of decision makers at critical junctures in the process of political opening shape the range of choices and the kinds of risks they and their successors face subsequently. Although the conditions that make democratic consolidation more or less difficult may be a function of levels of socioeconomic development, the presence or absence of a civic culture, or the existence of a middle class, the decisions of leaders matter. Democracies are crafted, not born whole. This essay tries to identify the sources of difference in leadership style during a period of political reform. It proceeds from two observations. First, tactical and strategic choices of leaders are partly a function of the incentive structures political and economic institutions offer. Electoral rules, the amount of central control over important electoral resources such as the media, participation in regional monetary agreements—all of these institutions shape the options available for building coalitions.

Finding stable African governments, not simply governments that support a western agenda, is a problems for The West. European colonialism brought upheavals which destroyed the traditional states. In many places, western-style governments did not work and chaos followed. Sometimes, filling the vacuum would be the parallel rule of 'warlords', and local chiefs, vying for authority. Arms availability helped to back them up. The emergence of pressure groups in the US after the Civil War which brought about fundamental changes is contrasted with African dynamics. The pressure groups are in African but lack such springboards as a strong press and free universities.

The central nucleus of the amygdala (CeA) is a critical regulator of nociception, and its role in pain modulation depends on factors such as hemispheric location, neuropeptide release, and experimental model. Calcitonin gene-related peptide (CGRP) is a potent neuropeptide modulator within the CeA. Previous research has demonstrated its CeA nociceptive role in migraine, visceral, arthritic, and inflammatory pain murine models. The contribution of CeA CGRP to neuropathic pain is unclear. This study examined the effects of CGRP and its receptor antagonist, CGRP 8-37, in the CeA on mechanical and cold sensitivity in two mouse models of neuropathic pain: chemotherapy-induced peripheral neuropathy (CIPN) mediated by paclitaxel (PTX) and injury-induced neuropathy through the spared nerve injury (SNI) model. Mechanical and cold sensitivity were measured using the hindpaw von Frey and topical acetone drop assays, respectively. Neither CGRP nor CGRP 8-37 in the CeA had any significant effect on mechanical sensitivity in either neuropathic pain model. In the SNI-treated mice, CGRP infusion into either the left or right CeA reduced cold sensitivity in the left and right SNI-treated hindpaw, while CGRP 8-37 infusion into the left or right CeA increased cold sensitivity in the right SNI-treated hindpaw only. In PTX-treated mice, CGRP infusion into the left or right CeA decreased cold sensitivity of the contralateral paw only. These results suggest that CGRP in the CeA influences pain modulation in a complex manner that depends not only on the hemisphere and injury site, but also on the underlying cause of the neuropathic condition. This article presents the anti-nociceptive properties of calcitonin gene-related peptide (CGRP) signaling within the central nucleus of the amygdala during neuropathic pain-like conditions in mice. This dataset can serve to guide novel drug development for treating chronic neuropathic pain conditions.

Paraphrasing Félix Houphouët-Boigny, Ivoirian politician Camille Aliali once said, “Democracy is a system of government for virtuous people. It seldom works even in mature countries. We must be realistic. Our people are ignorant of the problems we face. They cannot be left to choose the solutions,...” In 1990, the president and his close associates changed their minds. On May 3, 1990, the president of Côte d’Ivoire announced the legalization of opposition parties and the intent to hold multi-party elections. On October 28, Ivoirians voted in their first multi-candidate presidential election, which pitted the eighty-five year old Houphouët against long-standing critic and candidate of the “democratic left” coalition, Laurent Gbagbo.

There is a more limited degree of 'urban bias' in Côte d'Ivoire than in most other African countries. Different explanations for relatively high producer price shares, reliable extension services, etc. are required for the periods 1960-70 and 1970-86. The arguments offered focus on the composition of the income portfolios of senior political elites and on the rise of special kinds of urban, informal associations that have acted as lobbying organisations on behalf of rural household members. The article seeks to dispel the notion that differences in opportunities for political participation alone can account for the variations in the outcomes observed in the African cases.

At the end of 1991, Kenya joined the growing number of sub-Saharan African countries with multiparty systems. However, Pres Daniel arap Moi's decision to permit registration of opposition parties does not represent a true multiparty system but merely a return to a set of rules that tolerates single-party dominance.
