中国产业集群的发展往往与一个或者多个专业批发市场相联系。中国的流通体制改革是中国专业化市场出现的重要原因。专业化市场对产业集群发展所起的作用可以说是中国特有的现象。先前的研究很少对中国这个特有现象给予重视。在产业集群和专业化市场的相互作用中,这些和产业集群有着密切联系的市场演变出不同的类型。专业化市场可以服务单个产业集群也可以服务多个产业集群。专业化市场可以细分为:房地产式,集群衍生式,中枢式和孵化器式。  相似文献

Damage models for natural hazards are used for decision making on reducing and transferring risk. The damage estimates from these models depend on many variables and their complex sometimes nonlinear relationships with the damage. In recent years, data‐driven modeling techniques have been used to capture those relationships. The available data to build such models are often limited. Therefore, in practice it is usually necessary to transfer models to a different context. In this article, we show that this implies the samples used to build the model are often not fully representative for the situation where they need to be applied on, which leads to a “sample selection bias.” In this article, we enhance data‐driven damage models by applying methods, not previously applied to damage modeling, to correct for this bias before the machine learning (ML) models are trained. We demonstrate this with case studies on flooding in Europe, and typhoon wind damage in the Philippines. Two sample selection bias correction methods from the ML literature are applied and one of these methods is also adjusted to our problem. These three methods are combined with stochastic generation of synthetic damage data. We demonstrate that for both case studies, the sample selection bias correction techniques reduce model errors, especially for the mean bias error this reduction can be larger than 30%. The novel combination with stochastic data generation seems to enhance these techniques. This shows that sample selection bias correction methods are beneficial for damage model transfer.  相似文献

This paper replicates an earlier study of faculty status and tolerance of political dissent by Abramson and Wences. The data support the hypothesis that length of residence on a university campus is inversely related to faculty tolerance of student dissent. The expected relationship between academic rank and tolerance was eliminated by controlling for longevity, but the predicted relationship between academic field and tolerance was unaffected. The effect of longevity appears to be independent of political orientations, and the data suggest that peer group influence is operative among faculty members.  相似文献

Summary.  Road safety has recently become a major concern in most modern societies. The identification of sites that are more dangerous than others (black spots) can help in better scheduling road safety policies. This paper proposes a methodology for ranking sites according to their level of hazard. The model is innovative in at least two respects. Firstly, it makes use of all relevant information per accident location, including the total number of accidents and the number of fatalities, as well as the number of slight and serious injuries. Secondly, the model includes the use of a cost function to rank the sites with respect to their total expected cost to society. Bayesian estimation for the model via a Markov chain Monte Carlo approach is proposed. Accident data from 519 intersections in Leuven (Belgium) are used to illustrate the methodology proposed. Furthermore, different cost functions are used to show the effect of the proposed method on the use of different costs per type of injury.  相似文献

Developing skilled and delicate approaches and interventions aimed at assisting families (or systems) to solve entrenched problems has been an exciting and stimulating aspect of family therapy over its relatively short existence. Recently, more and more authors have re-emphasised the need for respect and mutuality in dealing with clients, the need for the therapist to be aware of the clients' frames of reference and idiosyncratic solutions, some arguing that it is preferable to take less of the expert, interventionist stance. The necessity for empathy underlined in many earlier approaches to therapy is mentioned, though generally ‘in the small print’, in the reports of the processes being investigated and developed. This article re-considers empathy, always known to be at the heart of the counselling/therapy1 process, but perhaps too easily assumed at present. It contends that empathy remains essential, that it can be understood more fully, and thereby used more effectively. Some of the traditional understandings of empathy, mostly from writings on individual therapy, are considered. Working with families and systems demands a broader understanding and different applications. The therapist must be capable of empathy with the context and the relationships as well as with individuals. While asserting that human beings are generally capable of empathy, the article examines some particular aspects of its use in therapy, particularly with families; it contends further that a fuller understanding of empathy can enrich the whole process of therapy. The article argues that empathy remains an indispensable guide to intervention with the family, the system or the person, whatever form the intervention (or non-intervention) may take.  相似文献

ABSTRACT

This article narrows in on the mundane yet extraordinary events surrounding migrant farm workers’ decisions to leave their state-approved employment and to seek a better life in Canada outside of state-managed circulatory labour migration. In so doing, this research contributes to conceptualisations of precarity, and of precarious status in particular, that are beginning to recognise its effects not only on workers’ economic survival, but also the more ordinary daily conditions surrounding workers’ sense belonging and personal autonomy. In their refusal to accept the terms of their contractual circulatory labour migration agreements through what is conceptualised here as an act of ‘escape’, workers claim a space of belonging that contradicts the precarity of their formal citizenship status. In carving out a space in which they may perform autonomy and self-determination in daily life, however, this rejection of contingent citizenship status intensifies the precarious material conditions governing workers’ relationship to the state.  相似文献

This study compares attitudes toward business legitimacy in three countries. Positive attitudes toward business legitimacy exist when there is a congruence between organizational activities and societal expectations. Businesses are concerned about the extent to which negative attitudes toward business legitimacy will lead to increased government regulation. The results suggest that business students in all three countries are similar in their attitudes toward business legitimacy; however, blacks have more negative attitudes toward business legitimacy than do whites. This study resulted in the validation of a scale that can be used to measure attitudes toward business legitimacy on a cross-cultural basis. Business legitimacy is a major concern in South Africa as the predominately white business community seeks to give the emerging black majority a stake in the existing economic system. This revised version was published online in August 2006 with corrections to the Cover Date.  相似文献

Disruptive behavior in adolescents is burdensome and may continue into adulthood if left unidentified. The strengths and difficulties questionnaire (SDQ) can screen for disruptive behavior, but its psychometric properties in high-risk samples and ability to predict delinquency warrant further investigation. In 1022 adolescents, we investigated the predictive validity (on average 1.9 years after screening) of the self-reported SDQ on disruptive behavior disorders and delinquency, measured with multi-informant questionnaires and structured interviews. We compared three scoring methods: total, subscale, and dysregulation profile scoring. In this high-risk sample, SDQ subscale scores predicted disruptive behavior outcomes best. Predictive values for the specific types of delinquency were small. Concluding, the SDQ can be used in high-risk settings for early identification of youth with disruptive behavior.  相似文献
