The nation's largest charter management organization is the Knowledge is Power Program (KIPP). KIPP schools are emblematic of the No Excuses approach to public education, a highly standardized and widely replicated charter model that features a long school day, an extended school year, selective teacher hiring, strict behavior norms, and emphasizes traditional reading and math skills. No Excuses charter schools are sometimes said to target relatively motivated high achievers at the expense of students who are more difficult to teach, including limited English proficiency (LEP) and special education (SPED) students, as well as students with low baseline achievement levels. We use applicant lotteries to evaluate the impact of KIPP Academy Lynn, a KIPP school in Lynn, Massachusetts that typifies the KIPP approach. Our analysis focuses on special needs students that may be underserved. The results show average achievement gains of 0.36 standard deviations in math and 0.12 standard deviations in reading for each year spent at KIPP Lynn, with the largest gains coming from the LEP, SPED, and low‐achievement groups. Average reading gains are driven almost entirely by SPED and LEP students, whose reading scores rise by roughly 0.35 standard deviations for each year spent at KIPP Lynn. 相似文献
Much of India’s corruption involves middlemen: go-betweens who bring citizens’ cases to the attention of state officials, producing results – for a price. Citizens pay bribes, often for benefits for which they already qualify, and much (but not all) of that money is passed on to officials by the middleman. On its face such arrangements would seem to benefit no one but the middleman himself, but closer examination shows that middleman corruption involves much more than a discrete material transaction. There are important intangible dimensions: officials’ status is reaffirmed, while for citizens government takes on a comprehensible human face. These dimensions of corruption become all the more important over time, for both reputational capital and expectations are built up that shape future transactions. Most important, middlemen reduce transaction costs for citizens and officials alike. Thus, while middleman corruption falls far short of the ideal sorts of market, government and personal systems of “micro-coordination” assumed in many accounts of the effects of corruption, it may well be a better way of getting things done than most of the alternatives actually available. The analysis yields a more subtle but precise view of how cultural factors – especially mediating social institutions – figure into the study of corruption, and may suggest reasons why extensive corruption and solid economic growth have coexisted in India for decades. 相似文献
There is a need to characterize Asian elephant ivory and compare with African ivory for controlling illegal trade and implementation of national and international laws. In this paper, we characterize ivory of Asian and African elephants using Schreger angle measurements, elemental analysis {X-ray fluorescence (XRF), inductively coupled plasma-atomic emission spectroscopy (ICP-AES), and inductively coupled plasma-mass spectroscopy (ICP-MS)} and isotopic analysis. We recorded Schreger angle characteristics of elephant ivory at three different zones in ivory samples of African (n=12) and Asian (n=28) elephants. The Schreger angle ranged from 32 degrees to 145 degrees and 30 degrees to 153 degrees in Asian and African ivory, respectively. Elemental analysis (for Asian and African ivory) by XRF, ICP-AES and ICP-MS provided preliminary data. We attempted to ascertain source of origin of Asian elephant ivory similarly as in African ivory based on isotopes of carbon, nitrogen and strontium. We determined isotopic ratios of carbon (n=31) and nitrogen (n=31) corresponding to diet and rainfall, respectively. Reference ivory samples from five areas within India were analyzed using collagen and powder sample and the latter was found more suitable for forensic analysis. During our preliminary analysis, the range of delta13C values (-13.6+/-0.15 per thousand and -25.6+/-0.15 per thousand) and delta15N values (10.2+/-0.15 per thousand and 3.5+/-0.15 per thousand) were noted. 相似文献
New Feminist scholarship in diverse disciplines, including the social sciences, suggests a distinctive female reality which finds itsbesr literary expression in contemporary speculative fiction by women. Feminist utopias, in particular, delineate alternative societies in which ‘female’ values predominate. In novels by Marge Piercy, Doris Lessing, Ursula Le Guin and many other women, readers may discover holistic and dynamic worlds different from both our current reality and the patriarchal tradition of utopian speculation. When women imagine the ‘good society’, dualistic divisions, often ranked hierarchically in current power structures, tend to disappear, Feminist speculative fiction heals such schisms as those between male and female, matter and spirit, public and private rights, ends and means, even technology and ecology. Although these ‘utopias’ are not perfect, nor intended to be, their depiction of more balanced and integrated societies affords a fresh perspective on traditional political and cultural problems. Ultimately, then, the newly released female imagination may provide us not only a fascinating literature but substantive directions for actual change. 相似文献
Community based livelihood interventions, which focus directly on increasing income and employment, have become an increasingly important component of large-scale poverty reduction programmes. We evaluate the impact of a participatory livelihoods intervention – the Tamil Nadu Empowerment and Poverty Reduction (Pudhu Vaazhvu) Project (PVP) using propensity score matching methods. The paper explores the impact of PVP on its core goals of empowering women and the rural poor, improving their economic welfare, and facilitating public action. We find significant effects of PVP on reducing the incidence of high cost debt and diversifying livelihoods. We also find evidence of women’s empowerment, and increased political participation. 相似文献
On 31 October 2018, Justice Dr S Muralidhar (then) at the Delhi High Court convicted 16 members of the Provincial Armed Constabulary (PAC) for, inter alia, the murder of 38 Muslim residents of Hashimpura, a neighbourhood in Meerut, Uttar Pradesh in the summer of 1987. In so doing, he described the events that unfolded in Hashimpura as the ‘targeted killing’ of ‘members of a particular minority community.’ The judicial recognition of targeted violence in contemporary Indian society forms the focus of the present article. The article contends that Muralidhar J’s reference to targeted violence paves way for the recognition of an important juridical concept that warrants further academic and legal engagement. By adopting a relational approach, I argue that the conceptual utility of the category of targeted violence lies in its ability to unmask the social relations that it implicates. Targeted violence is not aimed at individual actors, but social relations between perpetrators, individual victims and those who share the victims’ minority identity. Committed to the legal recognition of social experiences, I demonstrate how the category of targeted violence accurately reflects the experiences of and relations between different social actors. I further build a case for why and how legal and judicial responses to targeted violence ought to be informed and shaped by a recognition of its relational harms.
Suicide is a leading cause of death among adolescents in many industrialized countries. We report evidence from a mediation
model linking greater youth activity engagement, spanning behavioral and psychological components, with lower suicide risk
through five hypothesized intrapersonal and interpersonal mediating factors. Self-report survey data (15% French, 85% English)
were gathered from a community sample of 5,015 Canadian adolescents participating in a mental health promotion program. Youth
(Mage = 15.77, SD = 1.42, 50% female) were from two urban centers in southern Ontario, Canada. Youth engagement (youth’s most important
type of activity, frequency of involvement, and psychological engagement), suicide risk predictive factors (self-esteem, current
concerns, depressive symptoms, coping ability, and connections with others), and suicide risk (ideation and attempts) were
assessed. Consistent with the hypothesized mediation model, enjoyment and stress in youth’s most important activity and various
activity types were associated with the various hypothesized suicide risk predictive factors, which in turn were related to
suicide risk. Implications for conceptualizations of youth engagement as a multidimensional construct and for suicide risk
prevention efforts are discussed. 相似文献
