Conflict, food insecurity, and globalization:

"We explore how globalization, broadly conceived to include international humanrights norms, humanitarianism, and alternative trade, might influence peaceful and foodsecure outlooks and outcomes. The paper draws on our previous work on conflict as a cause and effect of hunger and also looks at agricultural exports as war commodities. We review studies on the relationships between (1) conflict and food insecurity, (2) conflict and globalization, and (3) globalization and food insecurity. Next, we analyze countrylevel, historical contexts where export crops, such as coffee and cotton, have been implicated in triggering and perpetuating conflict. These cases suggest that it is not export cropping per se, but production and trade structures and food and financial policy contexts that determine peaceful or belligerent outcomes. Export cropping appears to contribute to conflict when fluctuating prices destabilize household and national incomes and when revenues fund hostilities. Also, in these scenarios, governments have not taken steps to progressively realize the right to adequate food or to reduce hunger and poverty. We conclude by exploring implications for agricultural development, trade, and human rights policies."

The human right to food as a U.S. nutrition concern, 1976-2006:

"For 30 years, U.S. food and nutrition scientists and policymakers concerned with food and nutrition have explored the possibility of making the human right to food (HRF) the moral and legal cornerstone of U.S. domestic and international initiatives in this area. The U.S. government has consistently opposed formal right-to-food legislation, labeling it as overly burdensome and inconsistent with constitutional law. In contrast, anti-hunger advocates have favored a rights-based framework as a way to hold government accountable for improving the nutritional situation of its poorest citizens and for saving lives and preventing malnutrition in developing countries. The U.S. government has continually expanded food and nutrition assistance at home and abroad, but not within a human rights framework. What might a human rights perspective add, and what are the continuing rationales of the opposition? Using as touchstones U.S. government and nongovernmental organization (NGO) testimonies from the 1976 Right to Food Resolution congressional debate and the 1996 World Food Summit, which featured U.S. opposition to HRF language, the U.S. government and NGO HRF positions are traced from 1976 to 2006. Qualitative analyses of historical policy position papers, testimonies, research reports, and the popular nutrition literature are used to evaluate how human rights and the HRF—as framing and rhetoric—have influenced nutrition policy, public and official understanding, and outreach. In this documentation process, we also integrate information from the wider “human rights” positions of the food-and-nutrition advocacy community, including Food First, Bread for the World, the Food Research and Action Center, the community food security movement, and charitable food assistance agencies, to demonstrate where these different advocacy agents, organizations, and agendas fit in this process of advancing a HRF sensibility." from Authors' AbstractFood policy, Human rights, Right to food, malnutrition, Social welfare,

Conflict, food insecurity, and globalization:

"For more than two centuries, proponents and critics of an open global economy have debated whether the free flows of goods, services, and capital make the world more peaceful and food secure or instead exacerbate inequalities and hardships, fanning interclass or interethnic violence motivated by grievance and greed. Food security and pri-mary agricultural commodities have been largely left out of these discussions; the authors begin to fill these gaps... the paper recommends four agendas for further food policy consideration: first, more attention to equitable outcomes in food distribution and food production and trade programs, so that such food security programs do not further contribute to ethnic divisions favoring violence-prone grievance and greed. Second, more careful scrutiny of national marketing and financial policies that influence farmer and middlemen income, and who benefits from agricultural export crops. Third, the design of some type of compensation fund for sudden or certain “losers” in globalization, who face loss of livelihood and recruitment to violence when cash crops like coffee fail to deliver expected livelihoods. Fourth, and in sum, more systematic use of livelihood-security and rights-based frameworks that address local-level food security in the context of national food policy planning " from TextHunger, Conflict, war, Globalization, Crops, exports, coffee, Cotton, Human rights, Right to food, Fair trade,

Breaking the links between conflict and hunger in Africa

"Armed conflicts frequently lead to the destruction of food systems. Often, warring parties manipulate starvation as a deliberate tactic, using their control over access to food to attract and reward friends and humble and punish enemies. Such conflicts are “food wars,” not only because hunger is used as a weapon but also because food insecurity is both an effect and cause of conflict....National governments in Africa, together with global investors, whether private or public (aid donors), must include conflict-prevention considerations in the planning, implementation, and evaluation of development programs and projects.They should calculate savings from conflict avoidance as part of the returns to development spending. Such an approach can help break the links between conflict and food insecurity. " from TextConflict ,Access to food ,Hunger ,Conflict prevention ,development projects ,Food markets ,

Food from peace: breaking the links between conflict and hunger

"In this paper, Ellen Messer, Marc J. Cohen, and Jashinta D'Costa show how hunger is often a direct result of violence ... [and] how hunger can reciprocally cause conflict. ... The authors call for including conflict prevention in food security and development efforts, as well as new linkages between food security and development on the one hand, and emergency relief on the other" Foreword.Social conflict., Hunger., Conflict management.,

Contextual Detection of Anomalies in Hyperspectral Images

The majority of anomaly detectors in Hyperspectral Imaging use only the statistical aspects of the spectral readings in the image. These detectors fail to use the spatial context that is contained in the images. The use of this information can yield detectors that out perform their spatially myopic counterparts. To demonstrate this, we will use an independent component analysis based detector, autonomous global anomaly detector (AutoGAD), developed at AFIT augmented to account for the spatial context of the detected anomalies. Through the use of segmentation algorithms, the anomalies identified are formed into regions. The size and shape of these regions are then used to decide if the region is anomalous or not. A Bayesian Belief Network structure is used to update a posterior probability of the region being anomalous

Do children use different forms of verbal rehearsal in serial picture recall tasks? A multi-method study

Use of verbal rehearsal is a key issue in memory development. However, we still lack detailed and triangulated information about the early development and the circumstances in which different forms of rehearsal are used. To further understand significant factors that affect children’s use of various forms of rehearsal, the present study involving 108 primary school children adopted a multi-method approach. It combined a carefully chosen word length effect method with a self-paced presentation time method to obtain behavioural indicators of verbal rehearsal. In addition, subsequent trial-by-trial self-reports were gathered. Word length effects in recall suggested that phonological recoding (converting images to names - a necessary precursor for rehearsal) took place, with evidence of more rehearsal among children with higher performance levels. According to self-paced presentation times, cumulative rehearsal was the dominant form of rehearsal only for children with higher spans on difficult trials. The combined results of self-paced times and word length effects in recall suggest that ‘naming’ as simple form of rehearsal was dominant for most children. Self-reports were in line with these conclusions. Additionally, children used a mixture of strategies with considerable intra-individual variability, yet strategy use was nevertheless linked to age as well as performance levels
