Asset-based social welfare programs focus on helping low- to moderate-income citizens to accumulate wealth in the form of homeownership, savings, small businesses, and higher education. Individual development accounts, savings accounts in which account holders’ deposits are matched, are a vehicle often used in these programs. In a national demonstration of individual development accounts for children (children's savings accounts), low-income youth were interviewed to learn what helped them to save and what made it difficult to save. We describe the young people's perceptions of these factors, and conclude with implications for policy and program design. 相似文献

The motivation for this paper is to consider whether changes in conformity over time are likely to depend critically on agent behavior. To get some insight on this we use the framework of Chamley [Chamley, C., 1999. Coordinating regime switches. The Quarterly Journal of Economics 114, 869–905] and compare the dynamic of conformity in a setting where agents are rational to one where they are adaptive (or backward looking). This is followed by a more general discussion on the issue. 相似文献

This article examines the tendencies of LGBT intergenerational theater projects. By engaging with ideas of queer time, temporal drag, and the pervasive heteronormative imagery of heritability and inheritance, this article explores the possibility that LGBT intergenerational projects may generate some of the problems they aim to challenge. Through the lens of queer time, the article describes the normativity generated in LGBT intergenerational theater projects as a form of restrictive interpellation. The article explores the temporal complexities at play in such theater productions as The Front Room, a specific LGBT intergenerational theater project performed in the United Kingdom in 2011. The article concludes by noting some ways in which intergenerational theater projects might seek to work through the embodiment of the historical quotidian as a mode of resistance to normativity’s recirculation. 相似文献

This paper presents a tractable set of integer programming models for the days-off scheduling of a mix of full- and part-time employees working α to β days/week (cycle) in a multiple-objective, multiple-location environment. Previous models were formulated to specifically schedule part-time employees working either two or three days per week. These models were intractable because they required complete employee schedule information. The new models are deemed implicit optimal since they are required to supply only essential information. While the number of variables in previous models is an exponential increasing function of β-α, the size of three of the new models is independent of α and β. The first three models developed here (as in [18]) deal with the trade-offs between idle time, the number of employees required to work at multiple “locations,” and the size of the total labor pool. The inherent flexibility of the implicit modeling approach is illustrated by the presentation of various modifications of the basic models. These modifications permit the use of preference weights on the number of employee work days/week (cycle) or the minimization of payroll costs where differential pay rates exist. These latter models may also be formulated such that idle time is ignored, constrained or minimized. The execution time for the implicit models (on a CDC CYBER 730 computer with commercially available software) averaged well under five seconds on 1200 trial problems for the type of application considered in [18]. A solution was obtained in less than 46 seconds of CPU time for a trial problem which would have required over 1.4 million integer variables with previous models. The availability of optimal solutions was invaluable in the development of two heuristics designed to deal with the trade-offs of [16]. In an experimental analysis a previous heuristic produced results which averaged from 74 to 508 percent above optimum across six experimental conditions. The comparable new heuristic produced results which averaged from 3 to 8 percent above optimum for the same experimental conditions. The paper concludes by developing a framework to integrate the results of this research with the tour scheduling problem and by identifying several other areas for related research. 相似文献

ABSTRACTWith reference to the 2014 Umbrella Movement and Hong Kong’s uncertain fate come 2047, I ask how one un-imagines the cultural future of inhabiting the locality. As people take prompts from the present predicament to cope with real possibilities about the future, they realize that a strong embodiment of local consciousness permeates the sociocultural space. I discuss how such engagement takes place through cinematic experience, and examine tactics of the spectator’s critique centring around the erosion of hope at the core of everyday, intellectual and affective imagination. I trace the ways in which postcolonial subjects engage with hope and with the shock of hopelessness in a lived social imaginary. Examining in detail three differently representative recent films, namely, The Midnight After (2014. Dir. Fruit Chan, The Midnight After Film and One Ninety Films), Overheard 3 (2014. Dir. Alex Mak and Felix Chong, Sil-Metropole, Bona Film and Pop Movies) and Ten Years (2015. Dir. K. L. Ng (‘Local Egg’, Boon-deh dan), J. Au (‘Dialect’, Fong-yin), K. Chow (‘Self-Immolator’, Jee-fun jeh), F. P. Wong (‘Season of the End’, Dong sim), and Z. Kwok (‘Extras’, Fau gua), Ten Years Studio), I depict the modes in popular imagination that invoke people’s engagement with the ‘local’, albeit in its affective state. Accordingly, in the context of ‘externalized’ social realities, I identify three interlocking modes of cultural engagement, which I characterize as figurative, performative and prefigurative, respectively. In their ‘future’ imaginary, I look for ordinary people’s ways to face the absurdity of the status quo and the performativity of local struggles with the self. 相似文献

This study evaluated the effectiveness of the 2nd and 3rd editions of the Children First parent education programs for parents experiencing divorce or separation. Participants were 678 parents experiencing separation or divorce in 2 Midwestern counties. Changes from pretest to posttest on participants’ knowledge, attitudes, and likelihood of adaptive coparenting were assessed. Both editions of the program had a significant positive effect on all 3 measures of adaptive coparenting. The effect sizes from pretest to posttest for the 2nd edition were small, whereas the effect sizes for the 3rd edition of the program were nearly twice as large. Superiority of the 3rd edition might be due to an increased focus on explicit training on adaptive coparenting behaviors. 相似文献

Green roofs are emerging engineered ecosystems that provide multiple benefits, but many are constructed with nutrient-rich substrate and have been found to leach out high levels of phosphorus (P) in runoff. It is unclear, however, how long green roofs act as sources of P or what mechanisms are responsible for these net losses. We measured P concentrations in runoff water over 4 years from a 1–5 year old extensive green roof in Cincinnati, OH, USA, produced a model to predict runoff P levels into the future, and validated predictions using runoff from 2 nearby extensive green roofs. P concentrations in runoff from the focal green roof were on par with heavily fertilized agroecosystems and displayed strong seasonal dynamics and a rapid decline over the 4-year study. Runoff measurements and changes in substrate P content over a 2-year period were used to estimate a mass balance for green roof P. P loss from the substrate was substantial (4.55 ± 2.3 g P/m2/yr), but only a small portion of the loss was attributable to leaching of P in runoff (0.19–0.65 g P/m2/yr). Missing P may be attributed to a combination of plant uptake and altered P form and binding strength, but further research is needed to precisely identify the mechanisms of P depletion. Our results also suggest that these and similar extensive green roofs are likely to act as environmentally significant sources of P for 10 or more years following roof installation, highlighting the need for reductions in initial substrate P content. 相似文献

Food insecurity is a common social issue and households look to assistance from food pantries, which often have difficulty supplying fresh or nutritious food. A substantial amount of produce is left in the fields, which can be collected through gleaning. In a focus group with volunteer gleaners at a faith-based nonprofit organization that attempts to fill the gaps of food insecurity, the motivations, challenges, and benefits of volunteering were examined. Volunteering in gleaning generated a sense of collective purpose and community; it addressed deeply held religious and spiritual impulses; and it puts volunteers directly in contact with nature. 相似文献
