Desirable system performance in the face of threats has been characterized by various management concepts. Through semistructured interviews with editors of journals in the fields of emergency response and systems management, a literature review, and professional judgment, we identified nine related and often interchangeably used system performance concepts: adaptability, agility, reliability, resilience, resistance, robustness, safety, security, and sustainability. A better understanding of these concepts will allow system planners to pursue management strategies best suited to their unique system dynamics and specific objectives of good performance. We analyze expert responses and review the linguistic definitions and mathematical framing of these concepts to understand their applications. We find a lack of consensus on their usage between interview subjects, but by using the mathematical framing to enrich the linguistic definitions, we formulate comparative visualizations and propose distinct definitions for the nine concepts. We present a conceptual framing to relate the concepts for management purposes. 相似文献

Disordered gambling is best conceptualized as a continuum of severity. Previous research has demonstrated the utility of studying individuals at all points of this spectrum. The sequence of the development of gambling problems and change in gambling involvement along this continuum of severity is not well understood. The present study examined the interplay between cognitive distortions and gambling involvement in a population sample recruited in Alberta, Canada. Data from 1372 participants over 4 assessment waves (5 years) were used to generate a 2-factor latent structure using gambling fallacies and gambling involvement measurements. Structural equation modelling showed that cognitive distortions more strongly predicted future gambling involvement than the reverse relationship, using the comparative fit index (CFI) and the root mean square error of approximation (RMSEA) to assess the models. In addition, cognitive distortions declined over time, whereas gambling involvement remained stable. The results of the study suggest that focusing primarily on cognitive mechanisms in public health initiatives for gambling disorders may be a more effective strategy than focusing on behavioural solutions. 相似文献

The article discusses the nature of the tangled interaction between the ex-Soviet Central Asian republics and the outside
great powers – Russia, the United States and China. Although the so-called Great Game model is often used to explain the geopolitical
rivalry in the region, the current pattern of relations between various international actors is much more complex than a traditional
tug-of-war between the old colonial empires. While Russia's strategic role in Central Asia appears to be on the rise, the
capacity of the West to influence political developments in the region has diminished. However, the overall situation in Central
Asia remains volatile and its geopolitical landscape is far from being settled. 相似文献

The level of immigrant welfare dependency is the subject of heated debate in the majority of developed countries, which have experienced a significant increase in immigration in recent years. In both Europe and the US, the problem of potential excessive use of social transfers is beginning to bring real policy consequences. This article addresses this issue by presenting a quantitative assessment of welfare receipt in 17 European countries, as well as Yun decomposition of its differences between natives and immigrants. It adds to existing literature by comparing the levels of welfare dependence among EU and non-EU migrants for individual benefits including and excluding pensions, using recent data from EU-SILC. Results suggest that immigrants rely on welfare less often than natives, and receive lower benefits when they do. Those conclusions are reversed, however, when old-age benefits are not considered – especially in the case of non-EU migrants. 相似文献

The purpose of this research was to analyze the development of self‐concept during adolescence. Participants included 484 teenagers (226 boys and 258 girls) from middle‐class families in the Basque Country region of Spain (Mage = 14.99, SD = 1.81 in Time 1 and Mage = 15.64, SD = 1.80 in Time 2). Longitudinal analysis found differences in the general school dimension. Six dimensions (math, verbal, general school, physical abilities, parent relationships and same‐sex relationships) reported a linear trend with a decreasing monotonic pattern; self‐esteem fit a cubic trend and physical appearance a quadratic trend line. Males showed higher means in self‐esteem, math, physical abilities, physical appearance, emotional stability and parent relationships; and females had higher values in verbal and general school. 相似文献

The article focuses on the application of the Bayesian networks (BN) technique to problems of personalized medicine. The simple (intuitive) algorithm of BN optimization with respect to the number of nodes using naive network topology is developed. This algorithm allows to increase the BN prediction quality and to identify the most important variables of the network. The parallel program implementing the algorithm has demonstrated good scalability with an increase in the computational cores number, and it can be applied to the large patients database containing thousands of variables. This program is applied for the prediction for the unfavorable outcome of coronary artery disease (CAD) for patients who survived the acute coronary syndrome (ACS). As a result, the quality of the predictions of the investigated networks was significantly improved and the most important risk factors were detected. The significance of the tumor necrosis factor-alpha gene polymorphism for the prediction of the unfavorable outcome of CAD for patients survived after ACS was revealed for the first time. 相似文献

With the historical change of the socio-economic system in ex-communist European countries quality of life of the population changed dramaticaly, improving in some components and within certain social strata and deteriorationg in others. These changes are analysed within the framework of authentic development and quality of life components: economic, social, political, environmental, cultural and human. The major aspect of the changes is the enlargement of human choices in all of the components, and to different extents in different countries in transition. The future of the whole transition process lies in its sustainablity and ability to draw on its past experience as well as on the experience of the Western world. 相似文献
