The fundamental purpose of the decennial Census is an enumeration of the U.S. population at a particular “Census moment” for the purpose of apportionment. The “Census moment” for the 2010 Census occurred at 11:59 p.m. on April 1, 2010. This means that, ideally, all persons alive and living in the United States at that moment are included in the Census count, while any person not alive at that moment is excluded. In reality, this goal is challenging to achieve. Since the actual date of data collection often varies widely, it is possible that individuals are included, or excluded, in the count due to this discrepancy between the Census Day and the date of data collection. In this paper, I explore how the Census Bureau addresses this issue specifically when dates of birth after Census Day are encountered. First, I describe the three methods of data collection (Self-administered questionnaires, enumerator-administered questionnaires, and Telephone Questionnaire Assistance/Coverage Follow-Up operator-administered questionnaires), and how dates of birth after Census Day are addressed in each of these methods. Next, I explore related findings from the 2010 Census, including how many dates of birth after Census Day were found in the 2010 Census data, how they were processed according to data collection method, and how this impacted the final Census count. Finally, I discuss the performance of the new procedures related to dates of birth after Census Day that were implemented in the 2010 Census, along with implications for moving forward into future Censuses. 相似文献

There is a debate in the literature about the arguments of utility in expected utility theory. Some implicitly assume utility is defined on final wealth whereas others argue it may be defined on initial wealth and income separately. I argue that making income and wealth separate arguments of utility has important implications that may not be widely recognized. A framework is presented that allows the unified treatment of expected utility models and anomalies. I show that expected utility of income models can predict framing induced preference reversals, a willingness to pay-willingness to accept gap for lotteries, and choice-value preference reversals. The main contribution is a theorem. It is proved that for all utility functions where initial wealth and income enter separately, either there will be preference reversals or preferences can be represented by a utility function defined on final wealth alone. 相似文献

Life on Earth is driven by energy. Autotrophs take it from solar radiation and heterotrophs take it from autotrophs. Energy captured slowly by photosynthesis is stored up, and as denser reservoirs of energy have come into being over the course of Earth's history, heterotrophs that could use more energy evolved to exploit them.Homo sapiens is such a heterotroph; indeed, the ability to use energy extra-somatically (outside the body) enables human beings to use far more energy than any other heterotroph that has ever evolved. The control of fire and the exploitation of fossil fuels have made it possible forHomo sapiens to release, in a short time, vast amounts of energy that accumulated long before the species appeared.By using extrasomatic energy to modify more and more of its environment to suit human needs, the human population effectively expanded its resource base so that for long periods it has exceeded contemporary requirements. This allowed an expansion of population similar to that of species introduced into extremely propitious new habitats, such as rabbits in Australia or Japanese beetles in the United States. The world's present population of over 5.5 billion is sustained and continues to grow through the use of extrasomatic energy.But the exhaustion of fossil fuels, which supply three quarters of this energy, is not far off, and no other energy source is abundant and cheap enough to take their place. A collapse of the earth's human population cannot be more than a few years away. If there are survivors, they will not be able to carry on the cultural traditions of civilization, which require abundant, cheap energy. It is unlikely, however, that the species itself can long persist without the energy whose exploitation is so much a part of itsmodus vivendi.The human species may be seen as having evolved in the service of entropy, and it cannot be expected to outlast the dense accumulations of energy that have helped define its niche. Human beings like to believe they are in control of their destiny, but when the history of life on Earth is seen in perspective, the evolution ofHomo sapiens is merely a transient episode that acts to redress the planet's energy balance. 相似文献

This article explores the importance of new forms of governance in active labour market policies (activation) in two countries: Denmark and the Netherlands. Drawing on research with key stakeholders in these countries, we analyse how new governance, and particularly processes of contracting-out and localization, have found expression in recent reforms to activation. We conclude that localization and contracting-out may have a future role to play in the development of more locally responsive and individually focused services. But both countries have encountered problems in promoting joined-up services through local jobcentres, while contracting-out has not always led to the tailored, individually focused services envisaged by policy-makers. In both countries, there are also concerns that the restriction of the Public Employment Service to a 'gatekeeping and signposting' role will lead to inconsistencies in the quality of services, exposing the most disadvantaged to greater social risk. 相似文献

Research has established that exposure to a combination of diagnostic (i.e., relevant) and nondiagnostic (i.e., irrelevant) information results in predictions that are more regressive than predictions based on diagnostic information (Hackenbrack, 1992; Hoffman and Patton, 1997). This phenomenon has been labeled the dilution effect (e.g., Tetlock and Boettger, 1989) and has been documented when individuals make predictions. This study tests for the dilution effect when small groups make predictions, and examines the effect of using a procedure designed to reduce the dilution effect. Results indicate that group predictions are influenced by nondiagnostic information in the same manner as are individual predictions, and allowing participants to rate the diagnosticity of information prior to making predictions does not reduce the dilution effect. 相似文献

AbstractLean is endorsed as policy in practice in the UK but the challenges and complexities affecting Lean in healthcare are still to be adequately assessed. Through a qualitative single case study of an NHS organisation implementing Lean, 43 interviews with multi-disciplinary team members involved in Lean were conducted. The progress of Lean is found to be inhibited as medical professionals have failed to engage or provide clinical leadership in supporting the trajectory of Lean. This resulted in limited outcomes, sustainability implications, and failed projects. Lean is challenged by complexity and this is evident in conflicts between professional identity, corresponding status and clinical/managerial relationships. Medical professionals as a group have received a limited focus in papers assessing the progress of Lean in Healthcare from an operational perspective. Going forward, strategies for mitigating the negative impact of this can be developed to support operational managers in the healthcare domain. 相似文献
