City rankings that aim to measure the environmental sustainability of European cities may contribute to the evaluation and development of environmental policy of European cities. The objective of this study is to identify and evaluate the methodological characteristics of these city rankings. First, a methodology was developed to systematically identify methodological characteristics of city rankings within different steps of the ranking development process. Second, six city rankings (European Energy Award, European Green Capital Award, European Green City Index, European Soot-free City Ranking, RES Champions League, Urban Ecosystem Europe) were examined. Official websites and any methodological documents found on those websites were content analyzed using the developed methodology. Interviews with representatives of the city rankings were conducted to acquire any additional information. Results showed that the city rankings varied greatly with respect to their methodological characteristics and that all city rankings had methodological weaknesses. Developers of city rankings are advised to use the methodology developed in this study to find methodological weaknesses and improve their ranking. In addition, developers ought to be more transparent about the methodological characteristics of their city rankings. End-users of city rankings are advised to use the developed methodology to identify and evaluate the methodological characteristics of city rankings before deciding to act on ranking results. 相似文献

Abstract The recent ‘mobilities turn’ in the social sciences suggests that research always fixes mobility somehow in time and space, in order to understand it. Migration, being a form of mobility, has to be fixed on certain times and spaces in order to make it possible to define and research it. Being a geographer, I build on this insight in the first part of the article to re-read the critiques on post-war methodological nationalism. Reflecting on my own past research practice, I argue in the second part that leaving behind the methodological nationalism paradigm does not mean leaving behind the necessity to fix migration in time and space, on either the ontological or the practical methodological level. New ways of fixing are chosen and, out of recurring ontological and methodological choices, new migration stereotypes are developing such as what might be called ‘methodological ruralism’ in the case of Romanian migration. 相似文献

Abstract Building on the transnational approach to migration, this introduction outlines some elements of the programme of an emergent methodological transnationalism. This effort aims to de-naturalize the concept of the national within migration studies. First, the analysis identifies methodological challenges of migration studies, such as contextualization, the ethnic lens and the essentializing view on ethnicity. Second, it indicates the relevant conceptual elements which deal with these methodological challenges, such as the critique of methodological nationalism, cosmopolitanism and the relational concept of space. Third, it addresses the relevant methods, such as multi-sited ethnography, the mobile methods approach, as well as researchers' positionality and strategies of de-ethnicization, all of which correspond to the new epistemology of migration studies. Finally, it highlights the common characteristics of the contributions to this special issue, which go beyond the normative view of cross-border migration. 相似文献

The purpose of this paper is methodological. I begin by showing the methodological frailties of both the heart and brain approach to the criteria of death used in connection with organ transplantation. I then clarify what a definition is. Finally, I propose to abandon the definition of death, and suggest a pragmatic definition of ‘explantability window’. 相似文献

We have evaluated the methodological quality of the Rémic (microbiology guidelines — bacteriology and mycology) of the Société Française de Microbiologie 2007, using to AGREE criteria, which are consensual at an international level, in particular at the the WHO (World Health Organisation) and at the European Union. The methodological quality of the Rémic is sub-optimal. These shortcomings in quality are mainly observed in AGREE domain no 5 (applicability), in AGREE item no 5 (patients’ opinions were not considered), and in AGREE item no 23 (conflicts of interest were not declared). The users of the Rémic must be aware of these few methodological shortcomings in order for them to be careful before they put its recommendation in practice. In conclusion, we advise the editors of the Rémic to insert at least a methodological chapter in their next édition. 相似文献

Background
Quality indicators (QIs) are used in many healthcare settings to measure, compare, and improve quality of care. For the efficient development of high-quality QIs, rigorous, approved, and evidence-based development methods are needed. Clinical practice guidelines are a suitable source to derive QIs from, but no gold standard for guideline-based QI development exists. This review aims to identify, describe, and compare methodological approaches to guideline-based QI development.Methods
We systematically searched medical literature databases (Medline, EMBASE, and CINAHL) and grey literature. Two researchers selected publications reporting methodological approaches to guideline-based QI development. In order to describe and compare methodological approaches used in these publications, we extracted detailed information on common steps of guideline-based QI development (topic selection, guideline selection, extraction of recommendations, QI selection, practice test, and implementation) to predesigned extraction tables.Results
From 8,697 hits in the database search and several grey literature documents, we selected 48 relevant references. The studies were of heterogeneous type and quality. We found no randomized controlled trial or other studies comparing the ability of different methodological approaches to guideline-based development to generate high-quality QIs. The relevant publications featured a wide variety of methodological approaches to guideline-based QI development, especially regarding guideline selection and extraction of recommendations. Only a few studies reported patient involvement.Conclusions
Further research is needed to determine which elements of the methodological approaches identified, described, and compared in this review are best suited to constitute a gold standard for guideline-based QI development. For this research, we provide a comprehensive groundwork. 相似文献7.

Climate change is shifting species’ distribution and phenology. Ecological traits, such as mobility or reproductive mode, explain variation in observed rates of shift for some taxa. However, estimates of relationships between traits and climate responses could be influenced by how responses are measured. We compiled a global data set of 651 published marine species’ responses to climate change, from 47 papers on distribution shifts and 32 papers on phenology change. We assessed the relative importance of two classes of predictors of the rate of change, ecological traits of the responding taxa and methodological approaches for quantifying biological responses. Methodological differences explained 22% of the variation in range shifts, more than the 7.8% of the variation explained by ecological traits. For phenology change, methodological approaches accounted for 4% of the variation in measurements, whereas 8% of the variation was explained by ecological traits. Our ability to predict responses from traits was hindered by poor representation of species from the tropics, where temperature isotherms are moving most rapidly. Thus, the mean rate of distribution change may be underestimated by this and other global syntheses. Our analyses indicate that methodological approaches should be explicitly considered when designing, analysing and comparing results among studies. To improve climate impact studies, we recommend that (1) reanalyses of existing time series state how the existing data sets may limit the inferences about possible climate responses; (2) qualitative comparisons of species’ responses across different studies be limited to studies with similar methodological approaches; (3) meta‐analyses of climate responses include methodological attributes as covariates; and (4) that new time series be designed to include the detection of early warnings of change or ecologically relevant change. Greater consideration of methodological attributes will improve the accuracy of analyses that seek to quantify the role of climate change in species’ distribution and phenology changes. 相似文献

One of the main reasons for the insufficient realisation of nature conservation objectives, especially in competition with land use and development, is the lack of methodological standards. Existing standards are not widely accepted by the users, who often apply very different schemes and techniques for evaluation and monitoring, to work on the same kind of problems. In the complex social context of modern communities, that increasingly rely on standardised regulations, a loss of reliability and public acceptance of results can consequently occur.The demand for methodological standards in nature conservation increased rapidly during the past years, due to a more comprehensive overall concept including used or anthropogeneous ecosystems and landscapes and general globalisation trends, including nature conservation strategies and laws. In Europe the recent development within the European Union, especially the conservation concept of Natura 2000, requires harmonisation of planning, management and monitoring methods.Regardless of this, methodological standardisation is not yet a major topic in nature conservation sciences. Many disadvantages and obstacles of such standards are discussed, such as the fact that the complexity and individuality of nature forbids standardisation in general. However such arguments merge methodological and thematic standardisation. In a 3-year developmental study, the challenges and limits of standardisation in nature conservation were analysed, thematically focusing on conservation-related items of landscape planning in Germany. A board of experts, comprising outstanding conservationists from universities, research institutions and private enterprises produced draft papers for standardisation (called yellow prints). Further representative scientists and conservationists were involved in the stepwise definition of standards. Such drafts are now available for 5 methodological fields of landscape planning (fauna, vegetation, biotopes, evaluation schemes, landscape visions). They represent best practice in German landscape planning in these methodological fields.The developed procedures of standard-setting are applicable to other fields of nature conservation on regional and international levels as well. 相似文献

Biomedical innovation and translation are increasingly emphasizing research using “big data.” The hope is that big data methods will both speed up research and make its results more applicable to “real-world” patients and health services. While big data research has been embraced by scientists, politicians, industry, and the public, numerous ethical, organizational, and technical/methodological concerns have also been raised. With respect to technical and methodological concerns, there is a view that these will be resolved through sophisticated information technologies, predictive algorithms, and data analysis techniques. While such advances will likely go some way towards resolving technical and methodological issues, we believe that the epistemological issues raised by big data research have important ethical implications and raise questions about the very possibility of big data research achieving its goals. 相似文献

Aquatic environments harbour large and diverse microbial populations that ensure their functioning and sustainability. In the current context of global change, characterizing microbial diversity has become crucial, and new tools have been developed to overcome the methodological challenges posed by working with microbes in nature. The advent of Sanger sequencing and now next-generation sequencing technologies has enabled the resolution of microbial communities to an unprecedented degree of precision. However, to correctly interpret microbial diversity and its patterns this revolution must also consider conceptual and methodological matters. This review presents advances, gaps and caveats of these recent approaches when considering microorganisms in aquatic ecosystems. We also discuss potentials and limitations of the available methodologies, from water sampling to sequence analysis, and suggest alternative ways to incorporate results in a conceptual and methodological framework. Together, these methods will allow us to gain an unprecedented understanding of microbial diversity in aquatic ecosystems. 相似文献

The current guidelines of evidence-based medicine (EBM) presuppose that clinical research and clinical practice should advance from rigorous scientific tests as they generate reliable, value-free knowledge. Under this presupposition, hypotheses postulated by doctors and patients in the process of their decision making are preferably tested in randomized clinical trials (RCTs), and in systematic reviews and meta-analyses summarizing outcomes from multiple RCTs. Since testing under this scheme is predominantly focused on the criteria of generality and precision achieved through methodological rigor, at the cost of the criterion of realism, translating test results to clinical practice is often problematic. Choices concerning which methodological criteria should have priority are inevitable, however, as clinical trials, and scientific research in general, cannot meet all relevant criteria at the same time. Since these choices may be informed by considerations external to science, we must acknowledge that science cannot be value-free in a strict sense, and this invites a more prominent role for value-laden considerations in evaluating clinical research. The urgency for this becomes even more apparent when we consider the important yet implicit role of scientific theories in EBM, which may also be subjected to methodological evaluation and for which selectiveness in methodological focus is likewise inevitable. 相似文献

Assessment of systematic effects of methodological characteristics on candidate genetic associations
Badr Aljasir John P. A. Ioannidis Alex Yurkiewich David Moher Julian P. T. Higgins Paul Arora Julian Little 《Human genetics》2013,132(2):167-178
Candidate genetic association studies have been found to have a low replication rate in the past. Here, we aimed to assess whether aspects of reported methodological characteristics in genetic association studies may be related to the magnitude of effects observed. An observational, literature-based investigation of 511 case–control studies of genetic association studies indexed in 2007, was undertaken. Meta-regression analyses were used to assess the relationship between 23 reported methodological characteristics and the magnitude of genetic associations. The 511 studies had been conducted in 52 countries and were published in 220 journals (median impact factor 5.1). The multivariate meta-regression model of methodological characteristics plus disease category accounted for 17.2 % of the between-study variance in the magnitude of the reported genetic associations. Our findings are consistent with the view that better conducted and better reported genetic association research may lead to less inflated results. 相似文献

Since the earliest periods of primatology study, researchers have been aware of animals’ consistent individual differences
in behavior or personality. Many papers have been published on this subject, but they lacked a common theoretical and methodological
background. The present work is an attempt to provide such theoretical and methodological foundations to this field of biological
science. In the theoretical formulation section, “biological study of personality” is first derived as an extension of the
ethology paradigm, and non-human primate personality research is subsequently characterized as its strategic component. In
the methodology section, brief reviews and discussions are presented on subjective and objective personality assessment methods
with non-human primates with a reference to the reliability and validity concepts in human psychometrics. The work provides
a theoretical framework and methodological suggestions for non-human primate personality research. 相似文献

Predicting antibiotic resistance 总被引:2,自引:0,他引:2
The treatment of bacterial infections is increasingly complicated because microorganisms can develop resistance to antimicrobial agents. This article discusses the information that is required to predict when antibiotic resistance is likely to emerge in a bacterial population. Indeed, the development of the conceptual and methodological tools required for this type of prediction represents an important goal for microbiological research. To this end, we propose the establishment of methodological guidelines that will allow researchers to predict the emergence of resistance to a new antibiotic before its clinical introduction. 相似文献

Traditionally, researchers interested in understanding father involvement in the lives of young children have relied on mothers as proxy respondents for fathers, yet recent research has made noteworthy strides in collecting data from fathers themselves yielding an unprecedented wealth of data on fathers' involvement in their children's lives. Despite this progress, there remain many methodological challenges in conducting studies with fathers and their children. Therefore, this article highlights several methodological challenges, including the identification of fathers, recruitment of fathers as participants, and retention of participants in small-scale studies with longitudinal designs, and discusses the advantages and disadvantages of several strategies our research team and others have used to collect data from fathers. The paper concludes with a set of suggestions for improving methodological approaches in fatherhood research, as well as remaining challenges in this area of study. 相似文献

Morphometric analysis of the sciatic nerve and its principal branches in the pigeon (Columba livia)]

The methodological approach used in this study is to characterize the number, the density and the diameter distribution of myelinated fibers (MFs) and unmyelinated fibers (UMFs) in sciatic nerve and its main branches of pigeon. The results have shown that the fiber composition is quite variable because in pigeon there are relatively MF with thin myelin sheaths and MF with thicker sheaths. Our data suggest that morphometric analysis could represent a helpful methodological approach to better characterize these systems. 相似文献
