Conflict, Peace and Security in Africa: an Assessment and New Questions After 50 Years of African Independence

Since the independence processes in the African continent, armed conflicts, peace and security have raised concern and attention both at the domestic level and at the international scale. In recent years, all aspects have undergone significant changes which have given rise to intense debate. The end of some historical conflicts has taken place in a context of slight decrease in the number of armed conflicts and the consolidation of post-conflict reconstruction processes. Moreover, African regional organizations have staged an increasingly more active internal shift in matters related to peace and security, encouraged by the idea of promoting “African solutions to African problems”. This new scenario, has been accompanied by new uncertainties at the security level and major challenges at the operational level, especially for the African Union. This article aims to ascertain the state of affairs on all these issues and raise some key questions to consider.

Globalization and wage inequality in South and East Asia, and Latin America: A gender approach

In this paper we analyse the reasons behind the evolution of the gender gap and wage inequality in South and East Asian and Latin American countries. Health human capital improvements, the exposure to free market openness and equal treatment enforcement laws seem to be the main exogenous variables affecting women s economic condition. During the second globalization era (in the years 1975-2000) different combinations of these variables in South East Asian and Latin American countries have had as a result the diminution of the gender gap. The main exception to this rule according to our data is China where economic reforms have been simultaneous to the increase of gender differences and inequality between men and women.This result has further normative consequences for the measure of economic inequality. Theimprovement of women s condition has as a result the diminution of the dispersion of wages.Therefore in most of the countries analysed the consequence of the diminution of the gender gapduring the second global era is the decrease of wage inequality both measured with Gini and Theil indexes.

Location of multiple server common service centers or public facilities for minimizing general congestion and travel cost functions

We propose a model and solution methods, for locating a fixed number ofmultiple-server, congestible common service centers or congestible publicfacilities. Locations are chosen so to minimize consumers congestion (orqueuing) and travel costs, considering that all the demand must be served.Customers choose the facilities to which they travel in order to receiveservice at minimum travel and congestion cost. As a proxy for thiscriterion, total travel and waiting costs are minimized. The travel costis a general function of the origin and destination of the demand, whilethe congestion cost is a general function of the number of customers inqueue at the facilities.

Present day distribution and historical biogeography of the tribu Ophidiini (Ophidiformes, Ophidiidae, Ophidiinae) from the East Tropical Atlantic (CLOFETA area) and North-East Atlantic and Mediterranean (CLOFNAM area)

The present day geographic distribution of the Ophidiini tribe (Ophidiidae, Ophidiinae) in the Clofnam (North- Eastern Atlantic and Mediterranean) and Clofeta (Eastern Tropical Atlantic) areas is revised in this paper. Results show that Parohidion vassali is not a Mediterranean endemic species, and the presence of Ophidion barbatum in the Atlantic is confirmed. Moreover, the paper tries to analyse the historical events which could have caused the present situation of two genera, Ophidion and Parophidion, both in the Atlantic and in the Mediterranean. Although first fossil records of Ophidion and Parophidion date from the Pliocene, when considering all the historical events occurred from the existence of the Tethys Sea to the opening of the Atlantic and the Mediterranean formation, a much earlier origin of these genera seems to be more likely. The situation of Ophidion barbatum and O. rochei in the Mediterranean and Black Sea is also discussed

Pakistan, una realitat desdibuixada

Ja feia anys que ens ballava pel cap d'anar a Pakistan per fer la ruta del Karakorum, la carretera més alta del món, vorejada per pics imponents i rius de gran cabal. Un trajecte que connecta el Pakistan amb la Xina i ressegueix una part de la famosa ruta de la seda. Tot un seguit de fets inesperats afavoriren que el viatgeinicialment previst ampliés el seu centre d'atenció amb la visita al poble de Kalash, l'últim reducte animista del país, i els camps de refugiats afganesos de Peshawar. La nostraarribada al Pakistan és, en termes tant metafòrics com reals, tempestuosa. L'endarrerimenten l'enllaç Barcelona-Londres ens impedeix d'agafar l'avió que ens havia de portar cap aIslamabad i ens obliga a quedar-nos durant un dia a la capital britànica

Mongòlia: un paradís inhòspit?

Aquest article l'escrivim des del record. Des d'unrecord llunyà, l'estiu de 1994, un referent constant cada vegada que mencionem lessocietats tradicionals i de manera especial els pobles nómades. De fet, el motiu principaldel viatge va ser precisament el de conviure amb homes i dones que viuen en un marc social, polític i econòmic molt diferent al nostre: el marc de les societats preindustrials, el qual configura i configurarà per molt temps Mongólia. El punt de partida d'aquest viatge és Beijin (Pequín), des d'on iniciem un periple incert però que finalment ens deixa un bon gusc de boca. El mitjà per arribar a la capital de Mongòlia, Ulaan Bator, és el tren -el transmongolià que va des de la capital de Xina fins a Moscou i que actualment és utilitzat per molts xinesos que hi van a fer petits negocis

Learning to live together: an exploration and analysis of managing cultural diversity in ten early childhood development centres in South Africa

This study explores how South African Early Childhood Development (ECD) Practitioners and families meet the needs of the increasing number of children from diverse cultural backgrounds in their care. Research participants were identified through ten ECD centres located in two urban communities in the Eastern and Western Cape Provinces of South Africa. The values and attitudes held by Practitioners and families vis-à-vis cultural diversity was investigated, along with the knowledge and strategies they employ to manage cultural diversity in ECD programmes. The intercultural education model provides the necessary tools to address the challenges identified.

Impact of quality and environmental investment on business competitiveness and profitability: The case of travel agencies

Few studies have examined the combined effect of implementing quality and environmental management within the service sector. This void is more evident if we focus on segments in which small businesses predominate and even more so if we look for highly competitive sectors that are very variable and that have high business mortality. After analysing 198 surveys of Spanish travel agency managers using structural equations, it can be concluded that practices of quality management have a significant direct impact on business competitiveness but not on this business's financial results, at least directly. However, there is a significant relationship between environmental management practices and economic benefits. This article suggests that commitment to quality and the environment can allow small businesses in the service sector to have a competitive advantage that will separate surviving and ceased operations, particularly in sectors that are rapidly evolving and highly competitive.

African signatures of recent positive selection in human FOXI1

Background: The human FOXI1 gene codes for a transcription factor involved in the physiology of the inner ear, testis, and kidney. Using three interspecies comparisons, it has been suggested that this may be a gene underhuman-specific selection. We sought to confirm this finding by using an extended set of orthologous sequences.Additionally, we explored for signals of natural selection within humans by sequencing the gene in 20 Europeans,20 East Asians and 20 Yorubas and by analysing SNP variation in a 2 Mb region centered on FOXI1 in 39worldwide human populations from the HGDP-CEPH diversity panel.Results: The genome sequences recently available from other primate and non-primate species showed that FOXI1divergence patterns are compatible with neutral evolution. Sequence-based neutrality tests were not significant inEuropeans, East Asians or Yorubas. However, the Long Range Haplotype (LRH) test, as well as the iHS and XP-Rsbstatistics revealed significantly extended tracks of homozygosity around FOXI1 in Africa, suggesting a recentepisode of positive selection acting on this gene. A functionally relevant SNP, as well as several SNPs either on theputatively selected core haplotypes or with significant iHS or XP-Rsb values, displayed allele frequencies stronglycorrelated with the absolute geographical latitude of the populations sampled.Conclusions: We present evidence for recent positive selection in the FOXI1 gene region in Africa. Climate mightbe related to this recent adaptive event in humans. Of the multiple functions of FOXI1, its role in kidney-mediatedwater-electrolyte homeostasis is the most obvious candidate for explaining a climate-related adaptation.
