What changes must economics undergo, if it is to become a moreadequate discipline, furthering of survival and flourishing?This essay argues that a break must be made from contemporarymainstream economics at the level of ontology (i.e., about thenature of reality). Drawing on neglected traditions of pragmatistphilosophy and process metaphysics, some elements of ‘old’institutionalist economics, and late-twentieth century naturalscience, it demonstrates that ample argument exists for a viewof the world as open, evolving and permeated with value. Furthermore,feminist scholarship offers an explanation for why such a worldviewfaces an uphill battle for acceptance.  相似文献

Land-use change has a significant impact on the world’s ecosystems. Changes in the extent and composition of forests, grasslands, wetlands and other ecosystems have large impacts on the provision of ecosystem services, biodiversity conservation and returns to landowners. While the change in private returns to landowners due to land-use change can often be measured, changes in the supply and value of ecosystem services and the provision of biodiversity conservation have been harder to quantify. In this paper we use a spatially explicit integrated modeling tool (InVEST) to quantify the changes in ecosystem services, habitat for biodiversity, and returns to landowners from land-use change in Minnesota from 1992 to 2001. We evaluate the impact of actual land-use change and a suite of alternative land-use change scenarios. We find a lack of concordance in the ranking of baseline and alternative land-use scenarios in terms of generation of private returns to landowners and net social benefits (private returns plus ecosystem service value). Returns to landowners are highest in a scenario with large-scale agricultural expansion. This scenario, however, generated the lowest net social benefits across all scenarios considered because of large losses in stored carbon and negative impacts on water quality. Further, this scenario resulted in the largest decline in habitat quality for general terrestrial biodiversity and forest songbirds. Our results illustrate the importance of taking ecosystem services into account in land-use and land-management decision-making and linking such decisions to incentives that accurately reflect social returns.  相似文献

There is a broad literature linking social support to health, which includes evidence that social support from supervisors is positively associated with worker health. In addition, once workers experience a health concern, supervisors may play a key role in supporting workers, keeping them on the job despite health issues. However, there are few studies that investigate the day-to-day strategies supervisors utilize to support their workers and help them stay on the job despite health concerns. The study presented in this paper addresses this gap. Thirty-two supervisors from three companies were interviewed about their experiences supporting and accommodating skilled workers during flare-ups of a health condition. A grounded theory approach was used to analyze the text data and identify themes. Three key themes emerged from the data: 1) workplace policies provide the structure for mutual problem solving; 2) communication skills and existing relationships increase supervisor effectiveness; and 3) strategies were aimed at individual, interpersonal, and institutional supports. Supervisors regularly interact with workers to support and accommodate episodes of illness or pain. While supervisors employ novel and effective strategies, there is an opportunity to improve the range of strategies, better understand and utilize company policies, and facilitate appropriate communication about worker health concerns.  相似文献

Shopping has long been recognized as an indispensable tourist activity. Hong Kong's open-air markets, where a multitude of bargaining activities can be observed, ranked as the second most popular of the island territory's diverse range of attractions in 2008 in terms of tourist arrivals. To develop cutting-edge marketing strategies that promote tourists' enjoyment of their bargaining adventure and ultimately enhance the overall shopping experience, the study reported in this article was aimed at identifying the dimensions underlying tourists' perceptions of the importance of 18 bargaining motivators and 12 bargaining attitudes and types of bargaining behavior, respectively, and subsequently evaluating the predictability of these underlying dimensions on tourists' shopping contentment indicators (overall bargaining satisfaction, the likelihood of a subsequent visit, and the likelihood of recommending open-air markets to others). A non-probability quota sampling technique was used to survey 203 Asian and non-Asian tourists in Hong Kong. A multivariate approach encompassing factor analysis and multiple regression was employed: Factor analysis delineated four underlying dimensions of factors affecting bargaining intentions. “Value for money” was shown to be the factor rated most important to tourists' bargaining intention; similarly, two underlying dimensions of bargaining attitudes and behavior—“bargain for psychological well-being” and “bargaining intensity”—were identified. Multiple regression results indicated the statistical significance of “bargaining for psychological well-being” and “bargaining intensity” to the existence of positive relations between shopping contentment indicators.  相似文献

The tourism industry in China has undergone rapid development since 1978 and is foreseen as being the world's largest tourism market by 2020. However, no comprehensive review of literature in this context has been completed, and international academics have little understanding of China tourism research. This paper aims to provide an overview of 119 articles selected from six leading English language academic journals published from 1978 to 2008. Content analysis points to the evolving trend in Asian universities in terms of journal contributions. Consumer behavior has gained popularity as a research topic, and will likely remain as a prevalent research theme in the near future. A tendency toward multiple-authorship, rather than single authorship, and more sophisticated methodological procedures has also been found. Future analysis may focus on including other forms of publications and Chinese language journals to capture the full picture of China tourism.  相似文献

In this article, we present the results of a case study of an entrepreneur who successfully founded and grew a venture underpinned by a portfolio of strongly homophilous, dyadic ties. Building on our case, we discuss how the entrepreneur strategically constructed these ties through a form of narrative identity work, explore the shared identity narratives that he used to do so, and highlight the heterogeneous nature of the resulting tie portfolio. We go on to explore the factors that motivated the entrepreneur to purposefully construct an entrepreneurial tie portfolio in this way. Building on our findings, we discuss the nature of narrative identity work and its role in creating homophilous ties, explore the connection between the resulting shared identity narratives and trust, and discuss the central role of values in strategic homophily.  相似文献

This paper examines determinants of process innovation introductions across 115 (mostly) developing countries. Empirical research on process innovations lags behind product innovations. Accounting for firm characteristics, R&D, regulations and taxes, and corruption, results show that sole proprietors and R&D‐performing firms were more likely to introduce innovations, whereas greater prosperity made them less likely to do so. Corruption had a greasing effect, whereas firms in island nations were less likely to introduce, ceteris paribus. Effects of regulations and taxes and other firm characteristics were largely insignificant. Finally, some differences existed across manufacturing and service industries and across prevalence of innovation introductions.  相似文献

This article uses recent measures of the risk and return to investment in housing to estimate the effects of including a single family home in the investor portolio. We estimate the expected return and standard deviation of that return, as well as its correlation with other major investment classes.  相似文献

Small sample properties of t-tests are compared with those of tests based on relative goodness- of-fit in the context of the first order moving average time series model. Monte Carlo experiments reported in the paper suggest that the actual size of these t-tests greatly exceeds theoretical large sample significance levels, while conformity of goodness-of-fit statistics to the appropriate chi-square or F-distributions is much closer. The evidence presented suggests that practitioners are well advised to employ goodness-of-fit tests as a check on results of t-tests particularly when the latter indicate ‘significance’.  相似文献

The paper examines gains in efficiency from joint estimation of systems of ARMA processes where cross-correlation is due to contemporaneous correlation among disturbances. The asymptotic variance of joint estimates is derived and it involves only variances and covariances among purely AR processes corresponding to the AR and MA parts of the constituent processes. Small sample gains are evaluated by Monte Carlo methods. Application of joint estimation to two short-term interest rates is shown to result in more accurate post-sample predictions relative to both univariate models and the FMP econometric model.  相似文献
