Seventy percent of the rural population in sub-Saharan Africa does not use adequate sanitation facilities. In rural Benin, as much as 95% of the population does not use improved sanitation. By analyzing a representative sample of 2000 rural households, this paper explores why households remain without latrines. Our results show that wealth and latrine prices play the most decisive role for sanitation demand and ownership. At current income levels, sanitation coverage will only increase to 50% if costs for construction are reduced from currently $190 USD to $50 USD per latrine. Our analysis also suggests that previous sanitation campaigns, which were based on prestige and the allure of a modern lifestyle as motives for latrine construction, have had no success in increasing sanitation coverage. Moreover, improved public health, which is the objective of public policies promoting sanitation, will not be effective at low sanitation coverage rates. Fear at night, especially of animals, and personal harassment, are stated as the most important motivational factors for latrine ownership and the intention to build one. We therefore suggest changing the message of sanitation projects and introduce new low-cost technologies into rural markets; otherwise, marketing strategies will continue to fail in increasing sanitation demand.

Terms of use: Documents in AbstractPublic funding of water supply infrastructure in developing countries is often justified by the expectation that the time spent on water collection significantly decreases, leading to increased labor force participation of women. In this study we empirically test this hypothesis by applying a difference-in-difference analysis to a sample of 2000 households in rural Benin where improved water supply was phased in over time. Time savings per day are rather modest at 35 minutes: even though walking distances are considerably reduced, women still spend a lot of time waiting at the water source. Moreover, a reduction in time to collect one water container induces women to collect a higher number of containers per day. Our results indicate that time savings are rarely followed by increased labor supply of women: men are the first to be freed from water fetching activities.JEL classification: I38, J22, J16
The glycoprotein osteopontin is highly upregulated in central nervous system (CNS) disorders such as ischemic stroke. Osteopontin regulates cell growth, cell adhesion, homeostasis, migration, and survival of various cell types. Accordingly, osteopontin is considered an essential regulator of regeneration and repair in the ischemic milieu. Astrocytes are the most abundant cells in the CNS and play significant roles in health and disease. Astrocytes are involved in homeostasis, promote neuroprotection, and regulate synaptic plasticity. Upon activation, astrocytes may adopt different phenotypes, termed A1 and A2. The direct effects of osteopontin on astrocytes, especially in distinct activation states, are yet unknown. The current study aimed to elucidate the impact of osteopontin on resting and active astrocytes. We established an inflammatory in vitro model of activated (A1) primary astrocytes derived from neonatal wistar rats by exposure to a distinct combination of proinflammatory cytokines. To model ischemic stroke in vitro, astrocytes were subjected to oxygen and glucose deprivation (OGD) in the presence or absence of osteopontin. Osteopontin modulated the activation phenotype by attenuating A1‐ and restoring A2‐marker expression without compromising the active astrocytes’ immunocompetence. Osteopontin promoted the proliferation of active and the migration of resting astrocytes. Following transient OGD, osteopontin mitigated the delayed ongoing death of primary astrocytes, promoting their survival. Data suggest that osteopontin differentially regulates essential functions of resting and active astrocytes and confirm a significant regulatory role of osteopontin in an in vitro ischemia model. Furthermore, the data suggest that osteopontin constitutes a promising target for experimental therapies modulating neuroregeneration and repair.
The stigma of migraine, despite an impressive body of data on the epidemiological of migraine and the associated disability, burden and cost of migraine to patients, has not been fully evaluated as an important factor in the chronicization of the disease and social isolation of the patient. In this commentary, we present three points of view. From the point of view of a European advocacy body active in the field of migraine medicine, actions to improve the perception of migraine within the community regarding the stigma for people with migraine are presented at the personal, relational and occupational levels. From the point of view of a clinician who is an expert on migraine, proposals are made for treatment and rehabilitation paths specifically dedicated to the reintegration of these individuals into social contexts.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
