Balance sheets are potentially important when monitoring the economic situation of agriculture. As conventionally drawn up, they relate to fictional statistical units and require arbitrary decisions about what constitutes agricultural assets and liabilities. This artificiality undermines their validity. The implications of basing balance sheets on real institutional units are discussed. 相似文献
We construct new measures of fund style, performance and activity from linear combinations of off‐the‐shelf stock‐market indices. A fund's benchmark portfolio is a linear combination of two or more reference portfolios that in a least‐squares sense most closely approximates the fund's portfolio. The resulting linear combination scalar is itself a measure of fund style and the distance between a fund and its benchmark is a measure of fund activity. Our approach has a number of advantages over existing characteristic‐matching methods. We illustrate our approach using a data set of US institutional funds. 相似文献
The results of an experimental study of retail investors' use of eXtensible Business Reporting Language tagged (interactive) data and PDF format for making investment decisions are reported. The main finding is that data format made no difference to participants' ability to locate and integrate information from statement footnotes to improve investment decisions. Interactive data were perceived by participants as quick and ‘accurate’, but it failed to facilitate the identification of the adjustment needed to make the ratios accurate for comparison. An important implication is that regulators and software designers should work to reduce user reliance on the comparability of ratios generated automatically using interactive data. 相似文献
Little empirical research has been conducted on perceptions of the types of sustainability information dealt with by different managers in internal company processes. In this study the roles of different managers are distinguished based on contingency theory and using the categorisation in the sustainability balanced scorecard concept. Expected sustainability information types are identified for these roles and hypotheses are derived and tested about perceptions of the types of sustainability information in different management roles. Interviews identified 116 roles involved with sustainability information in a set of leading German and UK sustainability reporting companies. Results from analysing sustainability information types contingent upon different management roles contribute to the understanding of sustainability accounting systems and practices and how companies can best support different management roles with appropriate sustainability information. 相似文献
Merchants and manufacturers are rapidly adopting electronic decision aids to help sell a variety of merchandise. These systems provide product information or recommendations based on input from the consumer and affect the way consumers process information. A conceptual framework, based on information processing theory and three strategic consumer difference variables — goal orientation, autonomy, and expertise — is presented. Based on these differences, propositions are derived to guide design of effective electronic decision aids.
Zusammenfassung
Elektronische Entscheidungshilfen: Die Miteinbeziehung der Perspektive des Verbrauchers Händler un Hersteller verwenden in wachsendem Ma\e elektronische Entscheidungshilfen beim Verkauf einer Vielzahl von Waren. Solche Hilfen stellen Produktinformation bereit und liefern Empfehlungen auch aufgrund solcher Dateneingaben, die von der Verbraucherseite kommen, und sie beeinflussen die Art und Weise, wie die Konsumenten Information verarbeiten. Der Beitrag liefert einen begrifflichen Rahmen, der auf der Theorie der Informationsverarbeitung und auf drei Konsumentenvariablen — Zielorientierung, Autonomie und Kompetenz — aufbaut. Auf dieser Grundlage werden Vorschläge für die Gestaltung wirksamer elektronischer Entscheidungshilfen abgeleitet.
The European Child Safety Alliance is an initiative of the European Consumer Safety Association with a network of child injury prevention organizations within 25 Member States in Europe. The Alliance, launched in 2001, focuses on strategies that assist in the reduction of injury related deaths and disability amongst children 0 to 18 years of age in the European Union Members States. The Alliance work is done in partnership with stakeholders from various disciplines involved in child injury prevention in order to promote a coordinated and consistent approach across Europe. 相似文献
Evaluate the cost-effectiveness of primary vs secondary prophylaxis (PP vs SP) with pegfilgrastim to reduce the risk of febrile neutropenia (FN) in Non-Hodgkin’s Lymphoma (NHL) patients receiving myelosuppressive chemotherapy from a US payer perspective.
Methods:
A Markov model was used to compare PP vs SP with pegfilgrastim in a cohort of patients receiving six cycles of cyclophosphamide, vincristine, doxorubicin, and prednisone (CHOP) or CHOP plus rituximab (CHOP-R) chemotherapy. Model inputs, including efficacy of pegfilgrastim in reducing risk of FN and costs, were estimated from publicly available sources and peer-reviewed publications. Incremental cost-effectiveness was evaluated in terms of net cost per life-year saved (LYS), per quality-adjusted life-year (QALY) gained, and per FN event avoided over a lifetime horizon. Deterministic and probabilistic analyses were performed to assess sensitivity and robustness of results.
Results:
Lifetime costs for PP were $5000 greater than for SP; however, PP was associated with fewer FN events and more LYs and QALYs gained vs SP. Incremental cost-effectiveness ratios (ICERs) for PP vs SP for CHOP were $13,400 per FN event avoided, $29,500 per QALY gained, and $25,800 per LYS. CHOP-R results were similar ($15,000 per FN event avoided, $33,000 per QALY gained, and $28,900 per LYS). Results were most sensitive to baseline FN risk, cost per FN episode, and odds ratio for reduced relative dose intensity due to prior FN event. PP was cost-effective vs SP in 85% of simulations at a $50,000 per QALY threshold.
Limitations:
In the absence of NHL-specific data, estimates for pegfilgrastim efficacy and relative risk reduction of FN were based on available data for neoadjuvant TAC in patients with breast cancer. Baseline risks of FN for CHOP and CHOP-R were assumed to be equivalent.
Conclusions:
PP with pegfilgrastim is cost-effective compared to SP with pegfilgrastim in NHL patients receiving CHOP or CHOP-R. 相似文献
As high unemployment rates linger following the latest recession, job opportunities can be sparse, especially for older workers. This might prompt older Americans to seek out opportunities in self-employment. Alternatively, recession-related decreases in economic activity might make self-employment less attractive. Using the Health and Retirement Study, we find that unemployed respondents are more likely to enter self-employment and that these decisions are clearly affected by recessions, although the effects differ by recession and gender. Unlike men, women’s self-employment decisions are very sensitive to other sources of household income, and women are less likely to become self-employed the deeper the recession. 相似文献
Building understanding of overconfident executives is central to a growing literature that spans a number of disciplines. Much of this research has utilized unobtrusive, or indirect, measures to assess executive overconfidence from secondary data sources. We analyze the convergent and content validity of seven extant unobtrusive measures of executive overconfidence. The results of our analyses indicate that these measures do not exhibit adequate convergence, suggesting that existing measures are not measuring the same construct. Further, we administer a sort task to academic colleagues to assess whether scholars believe that the seven measures are adequately assessing the intended construct. The results of our sort task indicate that scholars did not categorize any of the seven measures as sufficient for measuring overconfidence. We conclude with suggestions for future research to address the inadequate convergent and content validity found in our assessment of extant measures of executive overconfidence. 相似文献
