There is a large literature suggesting that “WIC works” to improve birth outcomes. However, methodological limitations related to selection into the Women, Infants, and Children (WIC) program have left room for doubt about this conclusion. This article uses birth records from New York City to address some limitations of the previous literature. We estimate models with mother fixed effects to control for fixed characteristics of mothers and we directly investigate the way that time‐varying characteristics of mothers affect selection into the WIC program. We find that WIC is associated with reductions in low birth weight, even among full‐term infants, and with reductions in the probability that a child is “small for dates.” These improvements are associated with a reduction in the probability that the mother gained too little weight during pregnancy. Improvements tend to be largest for first born children. We also find that women on WIC are more likely to be diagnosed with chronic conditions, and receive more intensive medical services, a finding that may reflect improved access to medical care.

Since the early 1950s, the National Heart, Lung, and Blood Institute (NHBLI) has conducted a long series of influential randomized clinical trials in heart, lung, and blood diseases. The biostatisticians at the Institute have been central to the design, conduct, monitoring, and final analyses of these trials. The uniquely favorable deck of cards the group of biostatisticians at the Institute has been dealt over the six and half decades of the group's life has led to contributions that have had a major impact on the fields of biostatistics and clinical trials. The leaders of the NHLBI and its several Divisions have valued the independence, creativity, and collaborative interactions of statisticians within the Institute. The medical problems the Institute faced impelled the statisticians to develop methodology that would address questions of great public importance. Perhaps most importantly, the individual members of the group had a collective vision passed from member to member over time that new methodology must fit the questions being asked. The group has always had the technical ability to develop new methods and the conviction that they were responsible for ensuring that they could explain their methods to the clinicians with whom they worked. 相似文献

Over the last 20+ years, globalization has made international trade and investment more efficient and productive. In the absence of coordinated global regulatory regimes, it has also made multinational corporations (MNCs) impervious to social concerns in the countries where they operate. There is considerable debate in the academic, political, and business arena as to the causes of the apparently inequitable distribution of benefits between labor and capital. Notwithstanding, the relative merits of this debate, and facing tremendous societal pressure, companies have adopted voluntary codes of conduct to ensure that workers making products for them in poor and developing countries are protected from hazardous working conditions and receive wages that meet local laws and market conditions. These codes, however, suffer from a lack of credibility and proof of substantive compliance. A new type of nongovernmental organization (NGO) has emerged that monitors a company's compliance with prespecified standards and provides assurance to the external stakeholders that the company has fulfilled its voluntary obligations. From an historical perspective, this has been an innovative phenomenon where the monitoring organization purports to act as an honest broker to ensure all concerned that the company/industry has fulfilled its obligations. In this article, we undertake a thorough examination of two such organizations, that is, Fair Labor Association, and Social Accountability International, that have played a pioneering role in bridging the gap between societal expectations and corporate performance. We examine their governance structures, operating procedures, monitoring standards, and public disclosure of findings, and above all, their success in improving the level of corporate compliance with their self‐created codes or standards. Unfortunately, our findings and conclusions are disappointing. In our view, the two groups have mostly failed to meet their avowed goals. Rather than using their NGO status to help companies improve their code compliance, they have suffered from managerial capture and have been reduced to corporate apologists. 相似文献

Infant phonetic perception reorganizes in accordance with the native language by 10 months of age. One mechanism that may underlie this perceptual change is distributional learning, a statistical analysis of the distributional frequency of speech sounds. Previous distributional learning studies have tested infants of 6–8 months, an age at which native phonetic categories have not yet developed. Here, three experiments test infants of 10 months to help illuminate perceptual ability following perceptual reorganization. English‐learning infants did not change discrimination in response to nonnative speech sound distributions from either a voicing distinction (Experiment 1) or a place‐of‐articulation distinction (Experiment 2). In Experiment 3, familiarization to the place‐of‐articulation distinction was doubled to increase the amount of exposure, and in this case infants began discriminating the sounds. These results extend the processes of distributional learning to a new phonetic contrast, and reveal that at 10 months of age, distributional phonetic learning remains effective, but is more difficult than before perceptual reorganization. 相似文献

This article examines current debates about gender equality, work‐life balance and flexible working. We contrast policymakers’ and organizational discourses of flexible working and work–life balance with managers’ and employees’ talk about these issues within their organizations. We show how, despite the increasingly gender‐neutral language of the official discourses, in the data studied participants consistently reformulate the debates around gendered explanations and assumptions. For example, a ‘generic female parent’ is constructed in relation to work–life balance and flexible working yet participants routinely maintain that gender makes no difference within their organization. We consider the effects of these accounts; specifically the effect on those who take up flexible working, and the perceived backlash against policies viewed as favouring women or parents. We argue that the location of work–life balance and flexibility debates within a gender‐neutral context can in practice result in maintaining or encouraging gendered practices within organizations. Implications of this for organizations, for policymakers and for feminist researchers are discussed. 相似文献

Neal, Sirgy and Uysal (1999) developed a model and a measure to capture the effect of tourism services on travelers quality of life (QOL). They hypothesized that travelers overall life satisfaction is derived from satisfaction with the primary life domains (e.g., family, job, health). Specifically, overall life satisfaction is derived from two sources of satisfaction, namely satisfaction with non-leisure life domains and satisfaction with leisure life. Satisfaction with leisure life is derived from satisfaction with leisure experiences that take place at home and satisfaction with travel/tourism experiences. Satisfaction with travel/tourism experiences results from satisfaction with trip reflections of the traveler (e.g., what the traveler remembers regarding perceived freedomfrom control, perceived freedom from work, involvement, arousal, mastery, and spontaneity experienced during the trip) and satisfaction with travel/tourism services. Satisfaction with travel/tourism services was hypothesized further to be derived from satisfaction with the service aspects of travel/tourism phases – pre-trip services, en-route services, destination services, and return-trip services. The model was tested using a study of university faculty and staff. The original model was extended by hypothesizing the moderation effect of length of stay. Specifically, we hypothesized that the relationshipsin the model are likely to be more evident in relation to travelers who have more time to experience the tourism services than those who do not. A survey of 815 consumers of travel/tourism services who reside in Southwest Virginia was conducted. As predicted, the data confirmed hypotheses as established in the original model. Satisfaction with tourism services affects travelers QOL through the mediating effects of satisfaction with travel/tourism experiences, and satisfaction with leisure life. Furthermore, the moderating effect of length of stay was confirmed by the data. In sum, this replication and extension study provided additional validational support of the original tourism services satisfaction measure in relation to QOL-related measures. 相似文献

The politics of private woman and public man 总被引:1,自引:0,他引:1
Summary Four themes run throughout this article. First, the tendency within male-stream analyses of political activity to exaggerate the extent of differences between women and men, and the recovery through feminist analysis of an unacknowledged political dimension underlying distinctive elements of women's experience.Second, the need to interrogate more rigorously the theoretical terrain on which the feminist engagement with the standard writings has taken place, particularly the unreflected emphasis upon the opposition between private woman and public man. Mapping political/ apolitical and male/ female onto the public/private divide encourages silence on boundaries of the political within the public sphere. It fails to address the political nature of the private, and implies that women are defined exclusively by the private sphere and men not at all.Third, the importance of re-examining men's political capacity, and distorted concepts and criteria of the political developed without sensitivity to gender. Male-stream writings misrepresent male political capacity by failing to recognize the parameters of men's political response - its parochialism and partiality, as well as the extent to which it is, like women's, reflective of private experience. Whether in political analysis or practical politics, it will not do to treat men's concerns, or policies formulated largely through traditionally male institutions, as the stuff of which politics is made.Fourth, the recognition that myopic visions of the political underlying misrepresentations of women's and men's political capacity are reproduced in many accounts of the relation between the private and the public, the personal and the political. Against such short-sighted views of politics, it is crucial to assert that the boundary between private and public arenas does not mark the limits of the political, and indeed is itself constructed through political process. 相似文献

The public availability of detailed data from the 2001 Research Assessment Exercise in the UK allows an analysis of the publications cited in submissions to the Business and Management panel. Eighty per cent of the 9,942 publications submitted were journal articles. Submissions to the RAE can be scored in terms of the number of citations they make to journals that appear on various lists, such as the Financial Times list. The concentration of articles in a minority of journals, with 50% of all citations to just 126 journals, means that a core list of business and management journals can be compiled. The core list presented contains 562 journals out of the 1582 journal titles that were cited in Business and Management submissions. It includes all journals with more than two citations overall at least one citation in a 5* , 5 or 4 rated submission. It also includes all journals cited in the RAE from Starbuck's ranked lists of journals and the Financial Times list. 相似文献
