Geopolitiche africane e dinamiche giuridiche

2020

Africa is an immense continent, rich in resources and problems. The law has been and is useful, in various ways, as an instrument of hegemony and economic influence for the powers that play their geopolitical games there. The crisis of the traditional state, the competition of alternative subjects to it and bearers of their own regulatory systems in the global context, the cultural reshuffles originating from migratory phenomena and a growing cosmopolitanism are elements capable of influencing the speed and outcomes of the changes taking place.

National, regional, and global trends in systolic blood pressure since 1980: systematic analysis of health examination surveys and epidemiological st…

2011

Summary Background Data for trends in blood pressure are needed to understand the effects of its dietary, lifestyle, and pharmacological determinants; set intervention priorities; and evaluate national programmes. However, few worldwide analyses of trends in blood pressure have been done. We estimated worldwide trends in population mean systolic blood pressure (SBP). Methods We estimated trends and their uncertainties in mean SBP for adults 25 years and older in 199 countries and territories. We obtained data from published and unpublished health examination surveys and epidemiological studies (786 country-years and 5·4 million participants). For each sex, we used a Bayesian hierarchical mo…

Multimorbidity and perceived stress: a population-based cross-sectional study among older adults across six low- and middle-income countries

2018

BACKGROUND:\ud Stress in chronic conditions or multimorbidity (≥2 chronic conditions) has been reported to affect clinical outcomes but there are no studies on the association between stress and chronic conditions/multimorbidity among older adults in low- and middle-income countries (LMICs). Thus, we investigated this association among adults aged ≥50 years across six LMICs.\ud \ud METHODS:\ud A cross-sectional analysis using data from the World Health Organization's Study on Global Ageing and Adult Health (China, Ghana, India, Mexico, Russia, South Africa) was conducted. A perceived stress score [range 0 (lowest stress) -100 (highest stress)] was computed based on two questions from the Pe…

Handgrip strength and depression among 34,129 adults aged 50 years and older in six low- and middle-income countries

2019

Introduction: Handgrip strength is a simple and inexpensive marker of health and mortality risk. It presents an ideal risk-stratifying method for use in low and middle-income countries (LMICs). There are, however, no population-based studies investigating the associations between handgrip strength and depression in LMICs. We aimed to assess these associations among community-dwelling middle-aged and older adults using nationally representative data from six LMICs. Method: Cross-sectional data on individuals aged ≥ 50 years from the World Health Organization's Study on Global Ageing and Adult Health were analyzed. Depression was based on the Composite International Diagnostic Interview. Weak…

Anxiety symptoms and mild cognitive impairment among community-dwelling older adults from low- and middle-income countries.

2021

Abstract Aim Anxiety may be a risk factor for mild cognitive impairment (MCI) but there is a scarcity of data on this association especially from low- and middle-income countries (LMICs). Thus, we investigated the association between anxiety and MCI among older adults residing in six LMICs (China, Ghana, India, Mexico, Russia, South Africa), and the mediational effect of sleep problems in this association. Methods Cross-sectional, community-based, nationally representative data from the WHO Study on global AGEing and adult health (SAGE) were analyzed. The definition of MCI was based on the National Institute on Ageing-Alzheimer's Association criteria. Multivariable logistic regression analy…

La predicción de la satisfacción con la vida en personas mayores de Angola: el efecto moderador del género

2014

ResumenExiste abundante investigación que ha estudiado la satisfacción vital en personas mayores y ha encontrado evidencia empírica de sus mejores predictores. Cuando se estudia la satisfacción con la vida de las personas mayores y sus predictores se hallan diferencias en función del género incluyendo, por ejemplo, las interacciones con la viudedad. En este contexto, el presente estudio se ha centrado en los siguientes objetivos: (1) poner a prueba la invarianza en función del género de una medida de satisfacción con la vida, (2) predecir la satisfacción vital usando varias variables relacionadas con el proceso de envejecimiento y (3) poner a prueba el potencial efecto moderador del género …

Vestiges of the Mesoproterozoic Events in the Neoproterozoic Mozambique Belt: the East African Perspective in the Rodinia Puzzle

2003

Abstract Most of the geological and palaeogeographical models consider the Neoproterozoic supercontinent Gondwana (∼650-550 Ma) as the direct offspring of the disintegrated Mesoproterozoic supercontinent Rodinia (∼1300-750 Ma). One of the main classical sutures along which the dispersing Rodinia fragments were fused into a new supercontinent (Godwana) is identified as the Mozambique belt of East Africa. The calc-alkaline magmatism (∼1200-950 Ma) in northern Mozambique, southern Malawi and southern Tanzania is regarded as the sole evidence for fragmentation of Rodinia, which is traced within this Neoproterozoic orogenic belt. There are no unequivocal Mesoproterozoic (Kibaran) sediments in th…

La problématique de l'Etat de droit en Afrique de l'ouest : analyse comparée de la situation de la Côte d'Ivoire, de la Mauritanie, du Libéria et de …

2009

The question of the Rule of law arises more and more with much acuity in Africa in general and in West Africa in particular. The observable deficit of Rule of law in certain countries of this region is one of the root causes of belligerence and crisis with dramatic consequences: violation of Human rights, desinstitutionalization, refusal of democratic alternation, impunity, poverty, insecurity, etc…Côte d’Ivoire, Mauritania, Liberia, and Sierra Leone are not immune to this. These countries are characterized by particular situations in the light of the crisis they encounter and have encountered, as well as common issues in the long and difficult quest for the establishment of the Rule of Law…
