Construction and reconstruction of racialised boundaries: discourse,institutions and methods

Considerable research has been published on the divisions between the various groups of Israeli citizens. Researchers have mostly studied the socio‐economic and political ‘gaps’ as well as the cultural differences that exist between the various groups. However, very little (if any) research has examined the constructed boundaries themselves, and the conceptual frameworks on the basis of which they were instituted. This article aims to look at one of these boundaries, the one that has been constructed between Jews and Palestinians. In addition to the examination of its formative stages and the changes in its articulation as a result of historical and demographic factors, this article analyses its implications in various spheres of life. Furthermore, it dwells on the social reality that the constructed boundaries were meant to obscure.     

Data Gap Analysis,Indicator Selection and Index Development: A Case for Developing Economies

Sustainable Development Goals (SDG) and its measurement is a key policy focus across the globe. Despite existence of several indices and reporting agencies, it is a challenging task to identify progress, specifically in the case of developing economies. These economies are predominantly in Asia and Africa and have a great bearing on global performance. These countries have diverse geographical and cultural elements with an active sub-national institutional framework. Data gap coupled with poor data quality and limited financial support does not help their case. Without appropriate indicator selection and index measurement it is not possible to judge the actual current situation or compare the SDG situation around the world. This paper attempts a practical and simpler approach to overcome the constraints, provide direction and facilitate measurement of SDG position in such countries using the case of India. This is done by identifying gaps, suggesting a tailored approach to indicator selection and measurement and further, developing a suitable index for SDG measurement at the sub-national level. The results and findings should be of great interest for policy making and implementing agencies.

     

The use of selective estrogen receptor modulators on bone health in men

Selective estrogen receptor modulators (SERMs) represent a class of drugs that act as agonist or antagonist for estrogen receptor in a tissue-specific manner. The SERMs drugs are initially used for the prevention and treatment of osteoporosis in postmenopausal women. Bone health in prostate cancer patients has become a significant concern, whereby patients undergo androgen deprivation therapy is often associated with deleterious effects on bone. Previous preclinical and epidemiological findings showed that estrogens play a dominant role in improving bone health as compared to testosterone in men. Therefore, this evidence-based review aims to assess the available evidence derived from animal and human studies on the effects of SERMs on the male skeletal system. The effects of SERMs on bone mineral density (BMD)/content (BMC), bone histomorphometry, bone turnover, bone strength and fracture risk have been summarized in this review.     

A 14th Century Critique of Greek Philosophy: The Case of Ibn Khaldun

This article discusses the critique of Greek philosophy by a Muslim scholar of the middle age Ibn Khaldun (1332–1406 CE). It begins with a brief introductory background of Ibn Khaldun, followed by a trace of the elements of Greek philosophy in his writings. The main purpose is to track the line of argument Ibn Khaldun used in his criticism and the basic premises he used in his attempt to position himself in his critiques. This article ends with concluding remarks on Ibn Khaldun's real attitude and how he drew a balance between rejection of certain philosophic notions and the acceptance of reasons and logics as crafts practiced in human civilization.     

A control chart for multivariate Poisson distribution using repetitive sampling

Control charts using repetitive group sampling have attracted a great deal of attention during the last few years. In the present article, we attempt to develop a control chart for the multivariate Poisson distribution using the repetitive group sampling scheme. In the proposed control chart, the monitoring statistic from the multivariate Poisson distribution has been used for the quick detection of the deteriorated process to avoid losses. The control coefficients have been estimated using the specified in-control average run lengths. The procedure of the proposed control chart has been explained by using the real-world example and a simulated data set. It has been observed that the proposed control chart is an efficient development for the quick detection of the nonrandom change in the manufacturing process.     

Estimating the Health Impacts of Tobacco Harm Reduction Policies: A Simulation Modeling Approach

With adult smoking prevalence rates declining too slowly to reach national objectives, opinion leaders are considering policies to improve tobacco-related outcomes by regulating the composition of cigarettes to be (1) less harmful and/or (2) less addictive. Because harm reduction efforts may actually encourage higher cigarette consumption by promoting a safer image, and addictiveness reduction may increase the harmfulness of cigarettes by encouraging compensatory smoking behaviors, policymakers must consider the tradeoffs between these two approaches when proposing legislation to control cigarette content. To estimate health impacts, we developed a dynamic computer model simulating changes in the age- and gender-specific smoking behaviors of the U.S. population over time. Secondary data for model parameters were obtained from publicly available sources. Population health impacts were measured as change in smoking prevalence and the change in cumulative quality-adjusted life-years (QALYs) in the U.S. population over 75 years. According to the risk-use threshold matrix generated by the simulation, modifying cigarettes to reduce their harmfulness and/or addictiveness could result in important gains to the nation's health. Addictiveness reduction efforts producing a 60% improvement in smoking behavior change probabilities would produce a net gain in population health at every plausible level of increase of smoking-related harm that was modeled. A 40% reduction in smoking-related harm would produce a net QALY gain at every level of behavior change considered. This research should prove useful to policymakers as they contemplate giving the FDA the authority to regulate the composition of cigarettes.     

Tests for high-dimensional covariance matrices using the theory of U-statistics

Test statistics for sphericity and identity of the covariance matrix are presented, when the data are multivariate normal and the dimension, p, can exceed the sample size, n. Under certain mild conditions mainly on the traces of the unknown covariance matrix, and using the asymptotic theory of U-statistics, the test statistics are shown to follow an approximate normal distribution for large p, also when p?n. The accuracy of the statistics is shown through simulation results, particularly emphasizing the case when p can be much larger than n. A real data set is used to illustrate the application of the proposed test statistics.     

Asymptotic joint distribution of sample quantiles and sample mean with applications

Based on a sample from an absolutely continuous distribution F with density f, and with the aid of the Bahadur (Ann. Math. Statist. 37( 1966 ), 577-580) representation of sample quantiles, the asymptotic joint distribution of three statistics, the sample p^th and q^th quantiles (0 < p < q < l) and the sample mean, is obtained. Using the Cramer-Wold device, asymptotic distributions of functions of the three statistics can be derived. In particular, the asymptotic joint distribution of the ratio of sample p^th quantile to sample mean and the ratio of sample q^th quantile to sample mean is presented. Finally, consistent estimators are proposed for the variances and covariances of these limiting distributions.
