When Hurricane Katrina made landfall on the Mississippi Gulf Coast in August 2005, it immediately overwhelmed the abilities of local and state emergency management officials to respond to the ensuing disaster. Although the U.S. Coast Guard and some military units were on scene shortly after the passage of the storm, there seemed to be interminable delays before the military forces began to arrive in numbers to both provide humanitarian relief and secure the affected areas. This article analyzes the response of the National Guard, active-duty military, and Coast Guard forces through the lens of coordination. We find evidence of the successful use of both traditional hierarchical and network-based coordination; we also find support for Donald Kettl's idea of "contingent coordination."  相似文献

This paper reports on a number of Eurobarometer surveys undertaken by the European Commission as a way of reflecting on Brexit and the challenges it poses to European identity. Our work with the surveys has been undertaken in the context of developing an educational game (RU EU?) which will explore European identity. European citizenship and identity have been strongly promoted by the EU but, while they appear to have been accepted at an elite level, the EU—and the UK in particular—have so far not constructed a narrative which has been supported by ‘ordinary’ citizens. Brexit has therefore exposed the failings of European elites in this regard. That said, there is some evidence that the complexities of Brexit have led to a strengthening of European identity in the other EU 27 countries.  相似文献

Food security, or lack thereof, is a global issue, affecting millions of people worldwide. Although it has been determined that there is enough food on the planet to feed everyone, nearly one‐third suffer from some form of malnutrition. The purpose of this paper is to bring awareness to this global crisis. The introduction defines food security and food deserts, supported by global and U.S. statistics. Next, the paper discusses the federal and regional initiatives within the U.S. to eliminate food insecurity, including federal laws and individual state laws. The paper highlights the “Right to Farm” initiative promulgated by New York state, as well as the Farmers' Market of Troy, New York, as attempts to combat food insecurity. The paper then discusses another large metropolitan area in the U.S., Seattle, Washington, and its response to food insecurity: Seattle's “Farm‐To‐Table Initiative” and “Fresh Bucks” program. Next, the discussion turns to advancing technology and its ability to bridge gaps in food accessibility. For example, Sweden has implemented an unstaffed twenty‐four‐hour grocery store using technology to complete the transactions. Smiliar solutions are being tested in communities in China. Furthermore, Amazon GO, launched in 2016 in Seattle, Washington, is one of the most recent innovations, allowing shoppers to use an Amazon account to track their purchases. The paper concludes by calling on the more economically influential countries to prioritize food security in their respective nations.  相似文献

Maternal intimate partner violence (IPV) exposure has been linked to negative parenting outcomes. Studies suggest that parenting stress is an intermediary between IPV exposure and parenting, though past work has relied on small, clinically- referred samples. Moreover, it is unclear if parenting is differentially affected by a mother’s recent versus past history of IPV exposure, or whether a mother’s childhood abuse history moderates the associations of IPV with parenting stress and parenting behaviors. The current study examines whether recent IPV, versus past IPV, has stronger associations with parenting stress and parenting behaviors and tests whether maternal abuse history moderates these associations. Using structural equation modeling, we tested relations between IPV (frequency and recency), parenting stress, and parenting behaviors cross-sectionally and longitudinally in a large community sample of IPV-exposed low-income Hispanic and African American mothers of children aged 0–14 years (N?=?1159). We found that mothers who reported IPV exposure in the past year reported higher negative and lower positive parenting behaviors than mothers who reported less recent exposure. Further, we found that the frequency and timing of IPV exposure affected parenting indirectly through increased parenting stress. However, a childhood history of abuse did not appear to sensitize women to these effects. These findings suggest that psychological interventions aimed at reducing the subjective experience of parenting stress, as well as increased access to resources that reduce objective childcare burden, are important for promoting resilience among families exposed to violence.

Smallholdings in the rural areas of northwest Syria are a result of land fragmentation that is due to inheritance. Because of rapid population growth combined with land fragmentation, these smallholdings are increasing and cannot sustain the rural households whose sizes and needs are also increasing rapidly This situation has led to increasing numbers of males migrating to urban areas in Syria and to neighbouring countries looking for work opportunities. In addition, recent agricultural intensification trends seem to have led to the emergence of a waged labour force which, in the absence of male workers owing to significant rates of migration, is now predominantly female. Agricultural labour use depends upon household characteristics and resources (type of labour used, gender of labour waged/exchanged/familial). The article attempts to present a comprehensive analysis of household labour use in distinctive farming systems in one region of Syria that has undergone great change in recent decades, and examines the changes in the composition of the agricultural labour force. Secondary information, rapid ural appraisals and formal farm surveys were used to gather information on the households in a study area where different farming systems coexist. The results show that the decrease in landholding size, the resulting male migration, and land intensification have resulted in the expansion offemale labour in agriculturalproduction, which has been termed in this research a 'feminization of agricultural labour'. This suggests that agricultural research and extension services will have to work more with women farmers and farm workers, seek their wisdom and involve them in technology and transfer. This is not easy in conservative societies but requires research and extension institutions to take this reality into consideration in their programmes.  相似文献
