This article analyses European Union (EU) policy-making on the rights of third-country nationals (TCN) against the backdrop of theoretical literature on the transformation of citizenship. The aim is to evaluate why and to which extent EU policy expands citizenship rights to TCNs, thus redefining the criteria for membership in the European polity. The research emphasises the role of norms and frames in policy-making and is based on secondary sources, primary documents and semi-structured interviews. The analysis reveals how the combination of a principled conflict over citizenship and a strategic conflict over competence led to a legal framework characterised by ‘restrictive rights’ and ‘politics of categorisation’. ‘Restrictive rights’ means that membership rights are granted to TCN in principle, but subject to very restrictive conditions. ‘The politics of categorisation’ refers to the political construction of migrant categories that are subject to different rights-regimes. Both phenomena have the ambiguous effect of enabling the expansion of rights to non-citizens while at the same time creating new lines of division and mechanisms of exclusion. 相似文献

邹衍是战国时期阴阳学派的代表之一。纵观思想史或哲学史著作,邹衍及其思想常鲜少提及。从五德终始说、天道论和天地广大说三个方面,对邹衍思想进行探究。邹衍在史墨五行相胜说的基础上,结合思孟学派的五行学说,形成了自己的五德终始说;他的天道论即四时教令思想;天地广大说在一定程度上开阔了人们的视野,打破了人们狭隘的地域观念。 相似文献

This article proposes a CV chart by using the variable sample size and sampling interval (VSSI) feature to improve the performance of the basic CV chart, for detecting small and moderate shifts in the CV. The proposed VSSI CV chart is designed by allowing the sample size and the sampling interval to vary. The VSSI CV chart's statistical performance is measured by using the average time to signal (ATS) and expected average time to signal (EATS) criteria and is compared with that of existing CV charts. The Markov chain approach is employed in the design of the chart. 相似文献

Measuring the accuracy of diagnostic tests is crucial in many application areas including medicine, machine learning, and credit scoring. The receiver operating characteristic (ROC) surface is a useful tool to assess the ability of a diagnostic test to discriminate among three-ordered classes or groups. In this article, nonparametric predictive inference (NPI) for three-group ROC analysis for ordinal outcomes is presented. NPI is a frequentist statistical method that is explicitly aimed at using few modeling assumptions, enabled through the use of lower and upper probabilities to quantify uncertainty. This article also includes results on the volumes under the ROC surfaces and consideration of the choice of decision thresholds for the diagnosis. Two examples are provided to illustrate our method. 相似文献

This article, written by survivor artists, practitioners and academics (each moving between these different identities and associated voices), will explore a creative arts approach to social work (SW) education within the context of service user and carer involvement. In addition to building upon a developing literature base, the writers will draw upon their own experience and the experience of other service user and carer contributors as well as student and practitioner feedback. In doing so, this article will seek to analyse some of the ways the creative arts can be harnessed as a tool for a more radical, creative and critical approach to professional education and how this in turn can help develop more empathic, critically self-reflective and creative (in the broadest sense of the word) practitioners. In critiquing the more traditional service user and carer involvement approach, this article will attempt to show how the more innovative approach of the Survivor Arts Project can move us beyond an arguably more limiting ‘expertise through experience’ model. In outlining an emancipatory model which recognises the relevance of lived experience and places this within the context of survivor movements, focusing also on the skills and insights survivors bring to SW education, this article will detail the ways we can work towards developing a more vibrant and dynamic learning environment which values our life stories and recognises our strengths as well as the many different and overlapping identities which place us along a continuum that connects our lives and informs our practice. 相似文献

Smart manufacturing systems (SMSs) are envisioned to contain highly automated and IT-driven production systems. To address the complexity that arises in such systems, a standard and holistic model for describing its activities and their interrelationships is needed. This paper introduces a factory design and improvement (FDI) activity model and illustrates a case study of FDI in an electromechanical component factory. In essence, FDI is a reference activity model that encompasses a range of manufacturing system activities for designing and improving a factory during its initial development and also its operational phases. The FDI model shows not only the dependency between activities and manufacturing control levels but also the pieces of information and software functions each activity relies on. We envision that the availability of these pieces of information in digital form to integrate across the software functions will increase the agility of factory design and improvement projects. Therefore, our future work lies in contributing to standards for exchanging such information. 相似文献

Acrylamide forms primarily from a reaction between reducing sugars (e.g., glucose and fructose) and an amino acid (asparagine, Asn) formed naturally in foods, including potatoes. This reaction occurs when carbohydrate‐rich foods are heated at temperatures above 120 °C. Multiple potato varieties were transformed with potato genomic DNA that results in down‐regulation of the expression of the asparagine synthetase‐1 gene (Asn1), significantly reducing synthesis of free Asn, and consequently lowering the potential to form acrylamide during cooking. These potatoes with low acrylamide potential (LAP) were tested in agronomic trials, and processed into French fries and potato chips. Decreased levels of acrylamide were measured in these cooked food products when derived from LAP potatoes compared with those derived from conventional potatoes. These reductions can be directly attributed to reduction in Asn levels in the LAP potatoes. The corresponding average reduction in exposure to acrylamide from French fry and potato chip consumption is estimated to be 65%, which would amount to approximately a 25% reduction in overall dietary exposure. Considering that children consume nearly three times more acrylamide than adults on a per kg body weight basis, they would experience the most impact from the reduced acrylamide associated with LAP potatoes. The potential public health impacts, in context of dietary acrylamide exposure reduction, are discussed in this study. 相似文献

Although most traditional Muslim scholars condemn same-sex desires and acts, revisionist Muslim scholars have offered a more tolerant approach on this issue over the last two decades. Building on an essentialist approach to same-sex desires and acts, these scholars have argued that Islam accepts difference and diversity, including sexual diversity, as part of God’s creation. Homosexuality, which in their view is an innate disposition to the same sex, is an alternative sexuality and, thus, accepted by the Qur’an and Islam. This article argues that an essentialist approach is not suitable to defend all manifestations of same-sex desires and acts, not only because it is narrow (as it excludes both bisexual Muslims and homosexual Muslims who believe that their sexual orientation is socially constructed), but also because it cannot even argue the case for the view of homosexuality as inborn. This article proposes to open up the debate beyond essentialism and constructivism, which both have their limitations, to accommodate a more inclusive and tolerant Islamic approach to same-sex desires and acts. 相似文献

摘要:压力是气井和气藏生产动态分析的灵魂,很多动态分析方法都与压力有着直接的联系。然而,由于致密低渗透气藏产量低、压力下降快、关井压力恢复缓慢等生产特征,以及生产方式的限制,在生产过程中很难获得气井或气藏地层压力资料。压降法、产量不稳定分析法和产量递减曲线分析方法是气藏常用的气井生产动态分析方法,但由于地层压力资料缺乏,压降法和产量不稳定分析法也都受到了很大的限制,在衰减递减曲线分析方法的基础上对其进行修正,摆脱了压力资料的限制,通过和压降法对比分析,验证了修正衰减曲线分析方法在生产动态分析中的可靠性。 相似文献
