The Index of Function Suitability (IFS): A new tool for assessing the capacity of landscapes to provide amenity functions

Integrating social demands into landscape management has been proven difficult because of a lack of suitable measures. In order to address this issue this article describes the development of the Index of Function Suitability (IFS). This offers an integrated conceptual tool for incorporating social demands into landscape management. The IFS links preferences to land cover spatial patterns as it uses quantitative indicators for gauging differences between the preferred landscape patterns by users, for a certain activity related to an amenity function (e.g. hunting), and the land cover patterns of a given rural area (either at the present or from scenarios developed for the future). Introducing the measurement of the difference between the preferred spatial patterns and the landscape patterns occurring in a given landscape is a fundamental conceptual development represented in the IFS. By using the same set of indicators to quantify different land cover patterns, the IFS gauges quantitatively the differences between their spatial patterns, thus providing landscape managers with an indication of the suitability of changing land covers to support the selected amenity functions. In this paper, the conceptual aspects, as well as the methodological steps of the IFS were explained and further applied to one empirical case study in the Alentejo region of Portugal. This paper also examines both the strengths and weaknesses of the IFS approach along with a discussion for improvement.

Estimating Capital Inputs for Productivity Measurement: An Overview of U.S. Concepts and Methods

The U.S. Bureau of Labor Statistics (BLS) publishes measures of multifactor productivity, which are patterned after the Solow residual. Inputs of capital must be aggregated with inputs of labor. The theory requires a measure of the capital service flow, a rather abstract notion which is rarely observable. The BLS procedures for capital measurement are summarized, and the rationale for these procedures is explored. Implicit measures of capital services are derived from data on property income and data on historical investments which are detailed as to type of asset.     

Exploring radio frequency identification technology's application in international distribution centers and adoption rate forecasting

Radio Frequency Identification Technology's (RFID) application in the global supply chain has seen increased attention, and international distribution centers (IDC) are now playing a more crucial role in the global supply chain operation. This paper adopts structure equation modeling (SEM) to investigate the impact of three factors mainly based on the technology acceptance model (TAM): perceived usefulness, perceived ease of use, and the social norm on the use intention of an IDC. Empirical results indicate that a revised TAM could explain the RFID acceptance behavior. Perceived ease of use, perceived usefulness, and the social norm are demonstrated to have an effect on RFID acceptance intention. The choice of RFID adoption is also impacted by the supply chain's stakeholders. Factors that affect the adoption intention of an IDC thus include customers and partners' request, government policy, and competitors that have already adopted RFID. Furthermore, the study adopts the binary Logit model based on the stated preference method's data to predict the possible adoption rate of the RFID system in the adoption intention of an IDC. This empirical study shows that significant statistical determinants influencing RFID acceptance are: system purchasing fixed cost, variable cost, and perceived usefulness. Our model also predicts that the penetration of RFID application in Taiwan's international distribution centers could hit the 25% adoption rate. The study provides several managerial implications and suggests future research directions.

Developing Official Stochastic Population Forecasts at the US Census Bureau

The U.S. Census Bureau is approaching a critical decision regarding a major facet of its methodology for forecasting the United States population. In the past, it has relied on alternative scenarios, low, medium, and high, to reflect varying interpretations of current trends in fertility, mortality, and international migration to forecast population. This approach has limitations that have been noted in the recent literature on population forecasting. Census Bureau researchers are embarking on an attempt to incorporate probabilistic reasoning to forecast prediction intervals around point forecasts to future dates. The current literature offers a choice of approaches to this problem. We are opting to employ formal time series modeling of parameters of fertility, mortality, and international migration, with stochastic renewal processes. The endeavor is complicated by the administrative necessity to produce a large amount of racial and Hispanic origin detail in the population, as well as the ubiquitous cross-categories of age and sex. As official population forecasts must meet user demand, we are faced with the added challenge of presenting and supporting the resulting product in a way that is comprehensible to users, many of whom have little or no comprehension of the technical forecasting literature, and are accustomed to simple, deterministic answers. We may well find a need to modify our strategy, depending on the realities that may emerge from the limitations of data, the administrative requirements of the product, and the diverse needs of our user community.     

网络教育培训用户采纳意愿实证研究

随着网络技术和信息技术的迅猛发展,教育培训在社会生活中显得越来越重要,中国的教育培训市场也正在快速发展,据报告显示中国培训业规模正以每年30%的速度递增.在当今需要高水平、高知识层次人才的社会环境下,网络教育培训事业随之蓬勃发展.本研究基于技术接受模型,实证研究个体对网络教育培训服务的采纳行为.第一,基于技术接受模型和信任、网络外部性、感知费用、预期绩效等因素提出研究模型.第二,通过对问卷数据进行信效度和路径分析检验,验证影响因素间的假设,同时采用性别因素对个体使用网络教育培训服务的调节效应进行分析.研究结果显示,信任与网络外部性对感知有用性有直接影响,信任与感知有用性对使用意愿有直接影响,使用意愿对绩效预期有直接影响,而性别对个体使用网络教育培训服务的调节效应并不显著.最后对研究结果和不足进行讨论.
