Are Household Production Decisions Cooperative? Evidence on Pastoral Migration and Milk Sales from Northern Kenya
Market-based development efforts frequently create opportunities to generate income from goods previously produced and consumed within the household. Production within the household is often characterized by a gender and age division of labor. Market development efforts to improve well being may lead to unanticipated outcomes if household production decisions are non-cooperative. We develop and test models of household decision-making to investigate intra-household decision making in a nomadic pastoral setting from Kenya. Our results suggest that household decisions are contested, with husbands using migration decisions to resist wives' ability to market milk.Intrahousehold decision-making, household production, Kenya
Milk Money and Intra-Household Bargaining: Evidence on Pastoral Migration and Milk Sales from Northern Kenya
In this study, we investigate the impact of new market opportunities on Gabra nomadic pastoralists living in an arid climate in northern Kenya. The Gabra have recently experienced growth of milk marketing opportunities, and this change has caused a renegotiation of intrahousehold arrangements that affect households' location and migration decisions. We model three different outcomes of the household bargaining processes and test them empirically. Our results are consistent with a contested model of the household in which husbands locate households farther from towns in order to limit milk marketing opportunities.Livestock Production/Industries,
Perceptions of Risk within Pastoralist Households in Northern Kenya and Southern Ethiopia
Perceptions of risk may vary within households as well as across households and communities. In this paper, we take advantage of panel survey data collected quarterly over a period of 2 ½ years to see how perceptions of risk vary across individuals over time. The surveyed households are in pastoralist communities in Northern Kenya and Southern Ethiopia and the survey period coincides with a severe drought in this region and the beginning of the recovery. We identify the structural heterogeneity of the perceptions of risk of these individuals. Because of the nature of panel data, we can also test how the perceptions of risk are affected by shocks in previous periods. In particular, we ask how an individual's risk perceptions change when shocks happen to him or herself, to other members of his or her, family, or to members of his or her community. This allows us to ask how expectations adapt based on the things that are happening to others and allows us to look at issues of social networks and learning.Risk and Uncertainty,

Oral Cancer Awareness and its Determinants among a Selected Malaysian Population
Objective: To assess oral cancer awareness, its associated factors and related sources of information among a selected group of Malaysians. Methods: A cross-sectional survey was conducted on all Malaysian ethnic groups aged >= 15 years old at eight strategically chosen shopping malls within a two week time period. Data were analysed using chi-square tests and multiple logistic regression. Significance level was set at alpha<0.05. Results: Most (84.2%) respondents had heard of oral cancer. Smoking was the most (92.4%) recognized high risk habit. Similar levels of awareness were seen for unhealed ulcers (57.3%) and red/white patches (58.0%) as signs of oral cancer. Age, gender, ethnicity, marital status, education, occupation and income were significantly associated with oral cancer awareness (p<0.05). Conclusions: There was a general lack of awareness regarding the risk habits, early signs and symptoms, and the benefits of detecting this disease at an early stage. Mass media and health campaigns were the main sources of information about oral cancer. In our Malaysian population, gender and age were significantly associated with the awareness of early signs and symptoms and prevention of oral cancer, respectively.Article Link:

Educational Investments in a Dual Economy
This paper presents a simple two-period, dual economy model in which migration options may affect the informal financing of educational investments. When credit contracts are universally available and perfectly enforceable, spatially varied returns to human capital have no effect on educational investment patterns. But when financial markets are incomplete and informal mechanisms subject to imperfect contract enforcement must fill the breach, spatial inequality in infrastructure or other attributes that affect the returns to education create spatial differentiation in educational lending and consequently, in educational attainment. Although migration options can increase the returns to education, they can also choke off the informal finance on which poorer rural households depend for long-term, lumpy investments like children\u27s education
Perspectives on Development in Arid and Semi-Arid East Africa: Results of a Ranking Exercise
This study investigates perspectives on development held by individuals living in arid and semi-arid areas of northern Kenya and southern Ethiopia. Overall, we find that interventions to meet basic human needs (access to water, health care and education) are the most highly desired. Projects supporting pastoral livelihoods (livestock health and marketing-oriented, restocking and conflict resolution) are second most important, followed by those that support alternatives to pastoralism (cropping, other income generating activities). Econometric analysis indicates that variation in rankings is mostly driven by variation across communities rather than across households within communities, lending support to community-based approaches to priority setting
Mixed-mode oscillations and interspike interval statistics in the stochastic FitzHugh-Nagumo model
We study the stochastic FitzHugh-Nagumo equations, modelling the dynamics of
neuronal action potentials, in parameter regimes characterised by mixed-mode
oscillations. The interspike time interval is related to the random number of
small-amplitude oscillations separating consecutive spikes. We prove that this
number has an asymptotically geometric distribution, whose parameter is related
to the principal eigenvalue of a substochastic Markov chain. We provide
rigorous bounds on this eigenvalue in the small-noise regime, and derive an
approximation of its dependence on the system's parameters for a large range of
noise intensities. This yields a precise description of the probability
distribution of observed mixed-mode patterns and interspike intervals.Comment: 36 page
