如何有效利用建筑技术经济指标进行施工图设计优化——以某商务办公楼为例

随着城市化建设的不断发展,建设节奏也随之加快,项目建设的周期较之过去也正不断地被压缩。这种现状使得设计者在施工图设计时,对施工图设计的周密性降低,往往对建设成本和施工难易度等方面的考虑不足。这样设计的优化的过程就显得更为重要了,笔者通过多年的实践,以实际的项目为例,从利用建筑经济技术指标的角度探讨施工图设计的优化。     

Writing Ourselves at Risk: Using Self-narrative in Working for Social Justice

I have recently been thinking of how to be “virtuous” as I engage in doing qualitative research for social justice. In this essay, I explore the complexities and risks involved in representing the researcher-self amidst competing (and perhaps false) dichotomies of the personal/professional life and the scholar/activist. To do so, I deconstruct places in my scholarship where I was willing (consciously and unconsciously) to take risks, where I took risks but was socialized to conform, where I am still unwilling to take the risk and where I am currently writing the risky. The goal is to create a dialogue about the perplexities that surround representing the “researcher self” with goals for social justice.     

Outdoor recreation expenditures and the effects of spatial structure

Abstract

Visitor expenditure models have been the focus of substantial attention in outdoor recreation research because of their significance in estimating local economic impacts. At the disaggregate level models have usually included simple measures of distance decay and variables representing the attributes of households and supply features. Scholars have ignored the differential effects that the spatial structure of opportunities might have upon expenditures. This paper presents an analysis of the effects of spatial structure upon visitor expenditures for outdoor recreation in Oklahoma. Analyses are presented which identify and differentiate the relative effects of spatial structure upon visitor expenditures and the alternative forms of spatial diversification behavior consistent with such expenditure patterns.     

Measuring Women's Quality of Life: A Discussion of Alternative Approaches

This paper reports our experiences with the application of a number of alternative approaches to a study of women's economic circumstances and quality of life in a typical western city. The important work of, especially, Martha Nussbaum on the capabilities approach to evaluations of “quality of life” has highlighted pitfalls associated with the use of a narrow informational base in studies of women's lives and has emphasized the value of qualitative methods in these evaluations. However, to date, most discussions of the relevance of plural approaches to studies of women's lives have been conducted in the context of developing countries. This paper contributes a practical, current example of the relevance of such approaches to assessments of the lives of women in western countries as well. The research findings reported in the paper also cast further light on the importance of several, related themes in the literature on the capabilities approach, namely the importance of understanding how women's aspirations and expectations change with their economic and social experiences; and the importance of appreciating the social uses of language and how this affects the way in which women describe their lives.     

公允价值会计的反思

公允价值与历史成本之间的孰优孰劣一直就伴随着争议。我们不应该忽视公允价值固有的内涵缺陷及其与财务会计概念框架的冲突,以及在金融危机中的顺周期效应。文章将从会计决策有用目标和会计信息质量以及准则的经济后果角度重新反思公允价值会计。     

Managing Competing Institutional Logics in Public–Private Joint Ventures

Abstract

Cross-sector inter-organizational partnerships, alliances and networks have become extremely popular. Yet, we may expect competing societal-level institutional logics to play an important role in cross-sector alliances, hence making their management central to alliance success. This article responds to the general research question: How do participants of public–private joint ventures manage competing institutional logics? Based on in-depth interviews we empirically characterize two competing logics in a cross-sector collaborative and identify two practices used to cope with them.     

The out-of-sample forecasting performance of nonlinear models of regional housing prices in the US

This article provides out-of-sample forecasts of linear and nonlinear models of US and four Census subregions’ housing prices. The forecasts include the traditional point forecasts, but also include interval and density forecasts, of the housing price distributions. The nonlinear smooth-transition autoregressive model outperforms the linear autoregressive model in point forecasts at longer horizons, but the linear autoregressive and nonlinear smooth-transition autoregressive models perform equally at short horizons. In addition, we generally do not find major differences in performance for the interval and density forecasts between the linear and nonlinear models. Finally, in a dynamic 25-step ex-ante and interval forecasting design, we, once again, do not find major differences between the linear and nonlinear models. In sum, we conclude that when forecasting regional housing prices in the United States, generally the additional costs associated with nonlinear forecasts outweigh the benefits for forecasts only a few months into the future.     

Greenways: a sustainable leisure experience concept for both communities and tourists

This paper reviews the development of greenways/car-free trails as an alternative environmentally friendly communication system and assesses their strengths and weaknesses. It gives the results of a questionnaire survey of 1261 users along a 106-km greenway in Spain linking the Pyrenees with the Mediterranean Sea. Unlike previous studies, sampling was random and unequal probabilities of selection were properly accounted for. The results show a complex range of user profiles, tourist and non-tourist, their perceptions of the trail and some of the direct and indirect impacts of the greenway on the communities through which it passes. Management recommendations flowing from the survey are presented with the aim of increasing the use of accommodation services and businesses in the towns and villages near the greenway and helping create a more sustainable tourism system. The paper illustrates the potential importance of greenways in a future low-carbon tourism strategy adapting to climate change.     

Towards an understanding of social networks among organizational self-initiated expatriates: a qualitative case study of a professional services firm

Drawing on a qualitative case study of 51 organizational self-initiated expatriates (OSIEs) in a professional services firm, this article investigates the role of networks during expatriation and, specifically, in the development of learning that is beneficial to both the individual expatriate and the global operations of the firm. First, we investigate the extent to which individual motivations to engage in OSIE impact on the development of networks. Second, we investigate individual's experiences of network development. Third, we investigate individual perceptions of the benefits of networks for both organizations and individual actors. The paper will report that professionals initiating their own expatriation develop continually expanding and composite networks such that mobility and networks evolve in a seemingly symbiotic relationship. In doing so, it contributes to our understanding of the role of agency in network development and extends our understanding of organizational self-initiated expatriation as a relatively under-researched phenomenon.
