Over the last few decades several countries have turned to inflation targeting as a policy choice for instilling stability into their economies. Prior studies have shown that inflation targeting has reduced inflation in those countries without significantly impacting GDP. This study seeks to improve upon these results by identifying the impact of timing on the policy decision as well as its impact as related to specific regions of the world. The focus is on developing countries across six regions. We find significant regional variation in developing countries in our sample in terms of the direction of changes in inflation following a switch to the inflation targeting policy. Moreover, although the impact of inflation targeting on real GDP is minimal overall, there is a statistically significant increase in real GDP among developing countries in certain regions only, namely, Europe, Latin America, and the Middle East. 相似文献

Process capability (PC) indices measure the ability of a process of interest to meet the desired specifications under certain restrictions. There are a variety of capability indices available in literature for different interest variables such as weights, lengths, thickness, and the life time of items among many others. The goal of this article is to study the generalized capability indices from the Bayesian view point under different symmetric and asymmetric loss functions for the simple and mixture of generalized lifetime models. For our study purposes, we have covered a simple and two component mixture of Maxwell distribution as a special case of the generalized class of models. A comparative discussion of the PC with the mixture models under Laplace and inverse Rayleigh are also included. Bayesian point estimation of maintenance performance of the system is also part of the study (considering the Maxwell failure lifetime model and the repair time model). A real-life example is also included to illustrate the procedural details of the proposed method. 相似文献

Many procedures exist for testing equality of means or medians to compare several independent distributions. However, the mean or median do not determine the entire distribution. In this article, we propose a new small-sample modification of the likelihood ratio test for testing the equality of the quantiles of several normal distributions. The merits of the proposed test are numerically compared with the existing tests—a generalized p-value method and likelihood ratio test—with respect to their sizes and powers. The simulation results demonstrate that proposed method is satisfactory; its actual size is very close to the nominal level. We illustrate these approaches using two real examples. 相似文献

A Bayesian elastic net approach is presented for variable selection and coefficient estimation in linear regression models. A simple Gibbs sampling algorithm was developed for posterior inference using a location-scale mixture representation of the Bayesian elastic net prior for the regression coefficients. The penalty parameters are chosen through an empirical method that maximizes the data marginal likelihood. Both simulated and real data examples show that the proposed method performs well in comparison to the other approaches. 相似文献

Moderators of the Relationship Between Physical Activity and Alcohol Consumption in College Students

Abstract Objective: Among college students, several studies have found a positive relationship between physical activity and alcohol use. The current study tested gender, Greek status, and ethnicity as potential moderators of the physical activity-alcohol use relationship. Participants: Participants were college freshmen (n = 310) endorsing alcohol/drug use. Methods: Students completed questionnaires assessing a number of health behaviors. Results: Results indicated that gender and Greek status were significant moderators of the relationship between physical activity and alcohol consumption. There was a positive relationship between physical activity and alcohol use for men and Greeks, but not for females and non-Greeks. Conclusions: These findings suggest that exercise does not serve as a protective factor for any of the subgroups of college students studied and is positively associated with drinking among college students who are men and/or involved with the Greek system. 相似文献

Major sociospatial transformation processes are taking place, and so concepts such as tradition, distinctiveness, and identity have become fundamental but delicate factors in the context of the social environment. Consequently, identity has become not only a term, but rather a comprehensive theme and concept, in making new places and built environments. In this context of argument, this article elucidates the implication of identity at different scales. It emphasizes the importance and hybridity of urban identities and how they may become entities or even mechanisms to overcome globalization issues. This article looks at global examples to exemplify various manifestations of urban identities. This theoretical article aspires to promote debates that can benefit current research programs in the context of globalization, urban identity, and sociocultural diversity. Finally, the aim here for specifying different levels of urban identities is not necessarily toward categorizing them, but rather to identify their roles and propositions in various scales that are related to humans and their social environments. 相似文献

This study examined how Muslims living in the West were represented in English language textbooks in Ontario, Canada. The review showed that Muslims were consistently placed in inferior and dependent positions in relation to ‘white folks’ by focusing on their origins in violent and backward societies, their cultural deficits, social ineptitudes, conflicted identities, and low-status jobs. It is suggested that textbooks should encourage critical literacy by including a wider, more accurate range of depictions of Muslims in western societies to combat stereotyping. 相似文献

The EU/European political community’s reaction to irregular migrants is ambivalent. On the one hand, migrants are produced as people to be pitied, rescued, and saved. On the other hand, they are feared, despised, and left to die. The article explores this ambivalence from a gender perspective and asks how sovereign masculinities are produced through emotional performances in the politics of migration control and management. It will be argued that emotions such as fear, disgust, and compassion are performed in the biopolitical security governance of irregular migration by producing a “socially abject” life as its object. This is a life that is to be killed, despised, and saved. Encounters between the irregular migrant and a European border security actor constitute a neo-colonial masculinity. During the moment of the encounter with the other’s life, sovereignty is produced through emotional performances of border security actors. The discussion concludes with illustrations of how racialized bodies and lives are produced as objects of fear, disgust, and compassion through European neo-colonial masculinity. The article speaks to the debates in the literature on masculinities in global politics, emotions and politics, and critical border studies. 相似文献
