ABSTRACT

There is continuous pressure on public managers to adopt information and communication technologies (ICTs) to transform the way cities work. E-government research provides insights on the institutional, organisational, and individual factors that shape technology adoption and use. Yet most studies on small and medium sized cities use cross-sectional data or rely on small samples. We lack a systematic understanding of how technology use in smaller cities has changed over time and where these cities are lagging. Drawing from a multi-year, multi-method national study of city government technology use, we describe advancements and gaps in the enactment of a range of technologies, from social media to open data portals, and explore variation across city population, department type, and manager age. Our findings show that smaller cities still lag in the adoption of key features while local government managers are more inclined to adopt and positively perceive social media than traditional ICTs.  相似文献

Abstract

Over the past three decades, Russia has developed a set of institutions for the management of ethno-linguistic diversity based on the principle of ‘national cultural autonomy’. This article examines the positioning of these institutions within Russian society, arguing that while state-endorsed discourses locate them within the culture sphere—treated as distinct from political processes—there is in fact an interpenetration of ‘politics’ and ‘culture’. The article identifies why these institutions position themselves within the ‘cultural sphere’ while also supporting the country’s meta-narratives on inter-ethnic tolerance and, effectively, the political status quo. Soviet legacies of inter-ethnic relations continue to be socially embedded, yet within this framework some dissenting voices are also discerned.  相似文献

Headspace solid-phase microextraction (HS-SPME) is assessed as an alternative to liquid-liquid extraction (LLE) currently used for 3,4-methylenedioxymethampethamine (MDMA) profiling. Both methods were compared evaluating their performance in discriminating and classifying samples. For this purpose 62 different seizures were analysed using both extraction techniques followed by gas chromatography-mass spectroscopy (GC-MS). A previously validated method provided data for HS-SPME, whereas LLE data were collected applying a harmonized methodology developed and used in the European project CHAMP. After suitable pre-treatment, similarities between sample pairs were studied using the Pearson correlation. Both methods enable to distinguish between samples coming from the same pre-tabletting batches and samples coming from different pre-tabletting batches. This finding emphasizes the use of HS-SPME as an effective alternative to LLE, with additional advantages such as sample preparation and a solvent-free process.  相似文献

The paper sketches out an account of ambiguous and agonistic love by drawing on the work of Simone de Beauvoir, Axel Honneth and Hannah Arendt. To begin with, I reconstruct the ambiguity of love within the conceptual framework of a paradigm of recognition. I argue further that the social relation of love, understood as an intertwine between dependence and independence, entails a power dynamic. Insofar as the dynamic actualises as “power in concert” or “power with”, namely as mutual empowerment, love unfolds as free love. Finally, I show how agonistic love is damaged by turning into violent domination.  相似文献

University spinoffs, an important subset of high-tech start-up companies, operate in a context characterized by marked information asymmetries that limit their chances of obtaining financing. Given the uncertainty and imperfect information that characterize these investment opportunities, signals about their potential value deserve further attention. We investigate the relationship between the main stakeholders involved in the process of creating a university spinoff—that is, the academic founders, the university technology-transfer office, and private investors—focusing on the role of public grants as effective signals that attract private venture capital (VC) funding. Using the database of all spinoff companies established to exploit inventions assigned to the University of Michigan from 1999 to 2010, we determine how the funds provided through the university technology-transfer office influence VC follow-on funding and consequent spinoff growth, controlling for the spinoff’s technology, the founders’ human capital, and the network’s resources. The empirical results support a signaling effect of the commercialization funds provided by the university and suggest an indirect impact on the growth of the spinoff’s sales through the mediating effect of VC financing.  相似文献

Pulmonary polymethylmethacrylate (PMMA) cement embolism after kyphoplasty (KP) surgery is a quite frequent event as well as the pulmonary embolization of central venous catheter fragment. This report shows the case of a subject who, after KP, developed pulmonary embolism and who underwent thoracic surgery. After hospital discharge, the subject advanced a claim for damages toward the hospital where he was operated, complaining sensation of tenderness at the chest surgical scar and esthetic damage. To understand the nature of the embolism (either central venous catheter fragment or cement), chemical investigations were then ordered. Spectrometry identified the PMMA cement used for KP. When doubts rise about the origin of the embolized material, chemical investigations may reveal important data not only for clinical but also for forensic purposes.  相似文献

This paper examines legislative variations in LGBT identities, addressing the question: why and how do two largely Catholic states—Italy and Spain—endow different legal treatment to LGBT identities? Italy and Spain present important similarities in their legal, social and historical backgrounds. The legal cultures of both of these states have legal frameworks decriminalizing homosexuality. Nevertheless, they have approached same-sex unions in quite different ways. Spain has introduced same-sex marriage. Italy has hindered, consequently legal recognition remains fiercely contested and unrealized. Overall, it is argued that it is in the area of same-sex unions that some of the most significant changes have taken place in family law over the past decade in a number of jurisdictions. The paper argues that legal reforms in family law must be understood in terms of relation between society and law and must draw upon the concept of “culture”. The two jurisdictions appear to support the theoretical perspective that reforms and lack of reforms in family law are inspired by a number of contexts such as religious values, ideas of political morality and State interests.  相似文献

Duffy and ABO blood group genetic polymorphisms were studied by minisequencing analysis of single-nucleotide polymorphisms (SNPs) at nucleotide positions--33, 125, 265, and 298 of the Duffy gene and at nucleotide positions-261, 297, 467, 646, and 703 of the ABO gene. In an Italian population sample, we found four alleles and seven genotypes for the Duffy and six alleles and 16 genotypes for the ABO systems. The lower limit for reproducible results was 200 pg DNA, with a range of up to 10 ng and an optimum at 1 ng. All of the 16 analyzed inclusive paternity tests were also consistent with parentage and two out of four inconsistencies with parentage cases were excluded by one or more SNPs. Although Duffy and ABO SNP typing show lower informativeness than most current forensic tests, their robustness, the limited population distribution of FY* Fy type, and the sensitivity of the minisequencing technology suggest that these markers can be useful in selected forensic applications.  相似文献

Single-nucleotide polymorphisms of Y chromosome (Y-SNPs) are a class of markers of interest in forensic investigations, because many of them show regional specificity, providing useful information about the geographic origin of a subject or evidence under investigation. A first multiplex with 7 SNPs (M35, M89, M9, M170, M172, M45, M173), which occur in the basal branches of the phylogenetic tree and are able to assign a subject to known most frequent European haplogroups, was designed. SNP genotyping was accomplished by hot-start PCR with primers amplifying fragments between 96 and 136 nucleotides, minisequencing, and capillary electrophoresis of extension products. Ninety seven subjects of known geographic provenance were studied, of which 68 from Europe. Of these, 57 had mutations found more frequently in European haplogroups and 11 more frequent in Asian populations. Subjects from non-European countries were also examined and had haplogroups common in their regions of provenance. Experiments with low molecular weight DNA gave positive amplification from 1 ng of DNA for all seven SNPs.  相似文献
