Abstract: Intracranial hematomas, whatever its causes, represent an important disabling, and dreaded adult’s lesion. This brain’s condition has not well been studied in developing countries. The aim of our study is to overview the management of intracaranial hematomas in Abidjan. It is a retrospective analytical and descriptive study, involving patients who had been admitted and monitored by neurosurgeons for intracranial hematomas, documented in brain CT scan and had been operated on from 1 January 2007 to December 31, 2009 in Abidjan. These 30 patients were 23 men and 7 women. The average age was 58.6 years old. 90% of the patients were admitted with wakefulness issues. Half had a Glasgow score of less than 8. The brain scanner allowed identification of an intraparenchymal hematoma associated or not with a cerebral ventricle contamination in 28 patients. There were 18 external ventricle derivations with or without decompressive craniectomy and 12 independent decompressive craniectomy. The evolution was marked by 20 deaths. 10 patients (33.3%) survived. Among the survivors, the first attack and arterial hypertension were the only illness before the attack. None had blood in the membranes and all had Glasgow scores greater than or equal to 9 at admission. Around 7 out of 10 patients were operated on during the first 48 hours. The operative indications of intracranial hematomas are still the subject of controversy. By basing itself on criteria and rigorous clinical and neuroimaging selection, surgery could eventually contribute to the management of this pathology which has become very frequent in Africa.

Food and Nutrition Sciences (FNS) , 2013, DOI: 10.4236/fns.2013.49A2009
Abstract:

This study aims to develop infant flours fortified with iron and vitamin A, taken from local products such as powder from dried Moringa oleifera leaves and pulps of Parkia biglobosa to improve the nutritional status of children aged 6 to 24 months. Chemical analyses show that, for 100 g of local flours destined for children, there are adequate protein levels (between 7.00 ± 0.44 and 12.69 ± 0.44 g) and fat content (between 7.52 ± 0.35 and 16.26 ± 0.84 g), but that there are low levels of b-carotene and certain micronutrients Zn (0.67 ± 0.01 to 2.51 ± 0.19 mg), Fe (7.11 ± 0.90 to 12.70 ± 0.56 mg), Ca (0.67 ± 0.01 to 2.51 ± 0.19 mg), Mg (6.79 ± 0.19 to 24.99 ± 1.75 mg). Analyses of minerals and vitamins showed that Moringa oleifera leaf-powder (per 100 g) is rich in calcium (1443.90 ± 11.03 mg), magnesium (176.72 ± 0.73 mg), iron (53.75 ± 5.07 mg), zinc (17.58 ± 0.89 mg) and b-carotene (624.40 ± 0.41 μg ER). 100 g of Parkia biglobosa’s pulps is rich in magnesium (73.00 ± 1.14 mg), iron (14.82 ± 2.49 mg), zinc (7.79 ± 0.44 mg) and vitamin C (75.29 ± 0.00 mg). In conclusion, we believe that these two ingredients can be effectively used to fortify local infant flours in vitamin A and iron and contribute to eradicating malnutrition due to micronutrients deficiencies.

The End of Voters in Europe? Electoral Turnout in Europe since WWII  [PDF]
Pascal Delwit
Open Journal of Political Science (OJPS) , 2013, DOI: 10.4236/ojps.2013.31007
Abstract:

Over the past twenty years, the scientific community and politicians in consolidated democracies have been regularly alarmed by political and electoral participation, portrayed as undergoing a brutal and linear decline. Each election is now scrutinized in terms not only of its results but also of its level of electoral turnout. This paper deals with two important issues—the reality of changes in electoral turnout in Europe and the impact of the institutional constraint of compulsory voting in voter turnout levels—through an analysis of 402 elections held in thirty-five States from 1944 until December, the 31st 2009. We do observe a contemporary erosion of voter turnout but at this stage voters are not so impossible to find as some claim they are. Furthermore, the assumption that interest in, and the importance of, compulsory voting as an institutional constraint encouraging voter turnout is confirmed.

 

The Catastrophe Map of a Two Period Production Model with Uncertainty  [PDF]
Pascal Stiefenhofer
Applied Mathematics (AM) , 2013, DOI: 10.4236/am.2013.48A016
Abstract:

This paper shows existence and efficiency of equilibria of a two period production model with uncertainty as a consequence of the catastrophe map being smooth and proper. Its inverse mapping defines a finite covering implying finiteness of equilibria. Beyond the extraction of local equilibrium information of the model, the catastrophe map renders itself well for a global study of the equilibrium set. It is shown that the equilibrium set has the structure of a smooth submanifold of the Euclidean space which is diffeomorphic to the sphere implying connectedness, simple connectedness, and contractibility.

Applied Mathematics (AM) , 2014, DOI: 10.4236/am.2014.517259
Abstract: This paper shows existence and efficiency of equilibria of a production model with uncertainty, where production is modeled in the demand function of the consumer. Existence and efficiency of equilibria are a direct consequence of the catastrophe map being smooth and proper. Topological properties of the equilibrium set are studied. It is shown that the equilibrium set has the structure of a smooth submanifold of the Euclidean space which is diffeomorphic to the sphere implying connectedness, simple connectedness, and contractibility. The set of economies with discontinuous price systems is shown to be of Lebesgue measure zero.
A New Interpretation of the Hubble Law  [PDF]
Pascal Churoux
Journal of Modern Physics (JMP) , 2015, DOI: 10.4236/jmp.2015.69127
Abstract: We propose a new interpretation of Hubble law. Waves are observed in the observer space-time. It defines the observer proper time T. Space-time is composed of three spatial dimensions and three temporal parameters: proper-time s of the observed object, proper time T of the observer and integration time t (currently considered as relative time). Time origin is the birth of the universe. So, universe is stable; it can be seen as the comobile space of expansion theory. When changing space-time from the source to the observer, waves are seen cooling; this explains the redshift effect. The distance is defined as the product of the delay time with the local speed of light of the observer. The mistake between t and T can explain why universe is viewed as not only in expansion but also in acceleration whereas we think it is stable.
Belgian Communism in the Light of Its Vanishing (1976-1994)  [PDF]
Pascal Delwit
Open Journal of Political Science (OJPS) , 2018, DOI: 10.4236/ojps.2018.83023
Abstract: In the 1987 national elections, the Communist Party of Belgium (PCB-KPB) lost all parliamentary representation for the first time since 1925. This failure reflects the accelerated collapse of Belgian Communism in just a decade. The events of 1989 and 1991 in Central and Eastern Europe and in the USSR will then confirm the de facto disappearance of the PCB-KPB. The article goes back to the roots of the decline of a medium-size Communist Party, but showed political and social relevance from 1925 to 1985. The decline is due to the industrial and socio-demographic dramatic changes. The paper also tackles the political choices made in the seventies and eighties to understand it. In particular, it embraces the internal paralysis of the party faced with the challenges posed to all the European Communist Parties at this time, and its inability to deal with them.
Conspicuous Ethical Consumption  [PDF]
Pascal Stiefenhofer
Theoretical Economics Letters (TEL) , 2019, DOI: 10.4236/tel.2019.91001
Abstract:

This paper considers a group of consumers who have preferences over how a good is produced and distributed, rather its traits alone. Moreover, it is hypothesized that ethical preferences also depend on prices, and that prices inform consumers about the way goods are produced and distributed. The concept of conspicuous ethics is introduced in order to motivate the consumption of ethically produced goods. The paper states the assumptions and conditions representing the consumption behavior of the ethical consumer. It is shown that a price-dependent direct utility function provides the necessary structure in the characterization of the consumption behavior of the ethical consumer.

The power of the interviewer: A qualitative perspective on African survey data collection
Sara Randall,Ernestina Coast,Natacha Compaore,Philippe Antoine
Demographic Research , 2013,
Abstract: BACKGROUND African censuses and surveys remain dependent on interviewers for data collection. Data quality is assured through training and supervision. Many survey concepts are difficult to translate into African languages and some, such as "household", may have multiple criteria which are not fulfilled by everyone, leading interviewers to prioritise different criteria. Some questions introduce unfamiliar ideas which require considerable negotiation by interviewers to obtain acceptable answers. OBJECTIVE To identify key stages in the data collection process and domains where interviewer judgement and interviewer-respondent social dynamics play a substantial role in determining who is included in household surveys, and in shaping responses to questions. METHODS We analyse published definitions, enumerator manuals and qualitative interview data with households, interviewers, supervisors, trainers, survey organisers and analysts along the chain of data production and use in Tanzania, Uganda, Senegal and Burkina Faso. RESULTS Despite comprehensive training manuals and definitions, interviewers influence who is included in, and excluded from surveys. Interviewer versatility needs to include both persuasive social skills and an ability to follow precise wording. In Africa, where survey concepts are often different from local concepts and where interviewers are socio-economically distant from respondents, these persuasive social skills are required throughout the interview process with unknown impact on the data produced. Language diversity is a major barrier to harmonisation. CONCLUSIONS To improve survey data validity more effort should be made to understand the influence of interviewers on data in low-income settings. COMMENTS This submission covers important issues for demographers undertaking secondary analysis of African surveys, especially those without fieldwork experience.
Enzyme Inhibition Effect and Polyphenolic Content of Medicinal Plant Extracts from Burkina Faso
Mindiediba Jean Bangou,Martin Kiendrebeogo,Moussa Compaore,Ahmed Yacouba Coulibaly
Journal of Biological Sciences , 2011,
Abstract: In the present study, 36 plant extracts, belonging to 6 families from Burkina Faso were used to evaluate their glutathione-S-transferase (GST), acetylcholinesterase (AChE), carboxylesterase (CES) and xanthine oxidase (XO) inhibitory activities and their phenolic, tannin and flavonoids contents by using spectrophotometrical methods. At 100 μg mL-1, Lippia chevalieri, Eclipta prostrata, Lantana camara and Indigofera pulchra extracts showed the best percentage of inhibition by regulating GST, AChE, CES and XO activities, respectively. The phytochemical investigations showed that all plant extracts were rich in biological compounds, namely phenolic, tannin and flavonoids. Particularly Cassia mimosoides extract presented the best phenolic, tannin and flavonoid contents. This result indicated that phenolic from Ceasalpiniaceae, flavonoids from Combretaceae and tannin from Verbenaceae contribute significantly to the inactivation of CES, AchE and GST, respectively. However, no significant correlation was found between polyphenolic compounds content and XO inhibitory activity. Present findings could partially justify the traditional uses of these plants in the treatment of mental disorders, gout, painful inflammations and cardiovascular diseases.
