Patients decide on where to consume hospital services in Germany. Thus, the understanding of the exact hospital selection criteria and their weights is important. This research reviews the antecedents of hospital selection utilizing the conjoint methodology with regard to six questions. (1) Which are the relevant choice criteria, and (2) what are their weights? (3) Which criteria receive an increased importance in the absence of experience? (4) Do differences between compulsory and privately insured patients, (5) between hospitals with regard to their size, and (6) between female and male patients exist? The relevance and importance of nine pre-selected criteria are determined through two conjoint analyses. Experience is found to be most important followed by referral by general practitioner, certified quality management system, positive press coverage, recommendation by relatives and acquaintances and distance to the hospital. Reception area design and the personnel's friendliness, the website quality and the published quality report are less relevant. Without experience, reception area design, personnel's friendliness and distance to the hospital receive an increased importance. In addition, for some criteria notable discrepancies between female and male patients and between patients with different insurance policies are found. 相似文献

Jason Scott Smith's ambitious, some might say overly-ambitious,goal is to "construct a new narrative" of the New Deal's significanceby using the lens of political economy to examine and explainhow the policies initiated during that historical phase "revolutionizedthe priorities of the American state, radically transformingthe physical landscape, political system, and economy of theUnited States" (p. 1). Smith most certainly does not see NewDeal policies as failures that were incapable of getting theU.S. 相似文献

Chewing gum was foremost an American invention, Michael Redclifttells us in Chewing Gum: The Fortunes of Taste, a brief yetserious and engaging book that details how chewing gum cameto occupy a distinct place in the rise of American consumerism.Perhaps nothing signified the triviality of consumerism as chewinggum. It possessed what Redclift calls an "ephemeral quality,"it was an easily replicable mass product, and provided instantgratification. This ephemerality was complicated by 相似文献

Richard Abel argues that in the period from 1910, when the motionpicture "revolution" succeeded and the American film marketwas emancipated from French domination, to 1914, when foreignfilms were nearly eliminated from the U.S. market, the Americanfilm industry was characterized by widespread experimentationand innovation, especially in the areas of promotion practices,distribution strategies, content refinement, and audience development.Six chapters of Abel's Americanizing the Movies bring to theforeground the battle of 相似文献

This research estimates fiscal impacts of Wal-Mart in Ohio from 1985 through 2003. Using a panel of counties, and accounting
for spatial autocorrelation in an instrumental variable model I estimate impact of Wal-Mart and Super-Centers on selected
revenues and transfer payments. Among the findings is that the presence of a Wal-Mart increases local commercial property
tax assessments resulting in collection increases of between $350,000 and $1.3 million. There is also an 18–43% reduction
in per capita EITC claims in a county. However, Medicaid expenditures experience growth which amount to roughly 16 additional
cases attributable to a single Wal-Mart. The magnitude and statistical certainty of these findings, suggests that local fiscal
intervention, either through incentives or a “Wal-Mart Tax” is unwarranted.

Basel II consists of supervisory guidelines negotiated by representatives of central banks and national regulatory commissions
that were members of the Basel committee on Banking Supervision (BCBS). The BCBS is itself a regulatory response to globalization,
which is connecting national safety nets in market-driven ways. A country’s financial safety net is a social contract established
by short-lived agents for principals in long-lived economic sectors. Restraints placed on the authority of the BCBS members
to contract for their principals by domestic politics explains: why Basel II authorizes individual countries to implement
the agreement in markedly different ways; why US implementation of Basel II ran into so much doubt, controversy, and delay;
and how the implementation debate set small and large banks and the Federal Reserve and other federal regulators against one
another.

Falls from publicly owned climbing equipment are often cited as the major cause of injury on children's outdoor playgrounds and have been the focus of substantial interventions in the UK since the early 1980s. Analysis of national data on falls from climbing frames for 1988 to 2002 shows that the main discernible trend during this period is an increase in the occurrence of injuries to the lower arm. Whether this is attributable to a behavioural response to some of the interventions, or to some other factor, is unknown. 相似文献

Priorities for prevention activities and planning for services depend on comprehensive knowledge of the distribution of the injury-related burden in the community. The aim of this systematic review was to quantify the effect of being injured, compared with not being injured, on long-term mortality in working age adults. Cohort studies were selected that were population-based, measured mortality post-discharge from inpatient treatment, included a non-injured comparison group and related to working-age adults. Data synthesis was in tabular and text form with a meta-analysis not being possible because of the heterogeneity between studies. Eleven studies met the inclusion criteria. All studies found an overall positive association between injury and increased mortality. While the greatest excess mortality was evident during the initial period post-injury, increased mortality was shown in some studies to persist for up to 40 years after injury. Due to the limited number of injury types studied and heterogeneity between studies, there is insufficient published evidence on which to calculate population estimates of long-term mortality, where injury is a component cause. The review does suggest there is considerable excess mortality following injury that is not accounted for in current methods of quantifying injury burden, and is not used to assess quality and effectiveness of trauma care. 相似文献

The objective and aim of the study was to compile empirical data to quantify the underestimation of the true burden of drowning and to compare drowning rates using commonly reported codes compared with those revealed by use of the full range of drowning codes in ICD version 10. The authors reviewed mortality data (1999-2002) from Australia and the USA and compiled data to compare the burden of 'unintentional drowning' with that of 'all drowning'. In both Australia and the USA, drowning mortality is more than 35% higher when a full range of codes is examined. A more comprehensive representation of the drowning problem is needed to assist in strengthening prevention activities. 相似文献

Investors have always been interested in reducing inflation risk in their portfolios. However, investors face different types of inflation than those measured by the Consumer Price Index (CPI). Moreover, different asset classes can be used to hedge portfolio inflation. In this paper, we show how individual equities can be used to construct equity portfolios sensitive to customized inflation targets. We illustrate portfolios for three types of inflation: US headline CPI, Forbes Cost of Living Extremely Well Index, and the US Medical Care Price Index. We also show how alternative weighting schemes, such as minimum volatility and maximum inflation beta, can be used to construct inflation‐hedged portfolios. 相似文献
