Our study investigates the relationship between technology innovation and human development in technologically advanced countries using data from quarterly observations from the last decade of the twentieth century to the first two decades of the twenty-first century. This objective of this study is to implement Quantile-on-Quantile regression (QQ) technique that as formulated by Sim and Zhou (J Bank Finance 55:1–8, 2015) and the renowned Granger-causality in quantiles as proposed by Troster (Econom Rev 37(8):850–866, 2018) examine the basic relationship between the given quantiles of technology innovation and their effects on the quantiles of human development. Therefore, the outcomes of this study explain the overall interdependence of technology innovation and affect the overall human development index. It is enumerated that the empirical results indicate that a significant positive relationship exists between technology innovation and human development in all selected technologically advanced countries, predominantly in both low and high tails. Moreover, the outcomes of Granger causality quantiles indicate a bi-directional fundamental relationship between these two variables in the dataset of all countries. The outcomes of the observations are extended to the recent findings on these two variables’ nexus and imply a differential impact on the technologically advanced countries. This causality guides us to offer some specific policy recommendations to each group of countries.

In this study, the antioxidant enzyme activities such as (SOD, GSH, and CAT) and malondialdehyde (MDA) level which is the end product of lipid peroxidation, were determined from the serum samples taken from patients diagnosed with prostate cancer Van Yuzuncu Y?l University Medical Faculty of Educational Research and Training Hospital and ?stanbul Bagcilar Education Research Hospital. The SOD, GSH, and CAT activity of patient groups was found significantly lower than the healthy control group in patients with prostate cancer (p?相似文献

In this article I show how Bosniak (Bosnian Muslim) refugees reproduce, contest and construct their ethnic and religious identities. Using ‘ritual’ in a broad sense to refer to everyday routinized activities and practices that characterize family hierarchies and gender relations, as well as more easily identifiable religious rituals, I show that rituals assert belonging to a community and an identity, but are also, in the process of construction and contestation, selectively evoked and ignored. ‘The Other’ constructed through certain rituals is not merely the non–Muslim Bosnian (Serbs and Croats), but also, for refugees, other Bosnian Muslims who stayed behind. Moreover, engagement in secular and religious rituals, and the wider issue of identity constructions cannot be understood fully without exploring the dynamics between refugees and people who have remained in Bosnia. Competing constituencies claiming ‘Bosnianness’ and ‘Muslimness’ can be found across national boundaries and complicate the attempt to construct a community of believers or nationals, or both.  相似文献

This article explores how the significance of ethnic identity can vary within a stable population, using caste among Muslims in Hyderabad, India as a case study. While some Hyderabadi Muslims are still embedded in ethnic networks, most now experience ethnicity as elective and do not rely on a corporate caste group for their social connections. This reflects a decline in the value of caste identities, which no longer provide economic or political resources. Increasingly, Muslims seek status through education, profession, or income. Thus, most Muslims in Hyderabad experience caste membership, identity, and networks in a weakened or attenuated way.  相似文献

Projecting losses associated with hurricanes is a complex and difficult undertaking that is wrought with uncertainties. Hurricane Charley, which struck southwest Florida on August 13, 2004, illustrates the uncertainty of forecasting damages from these storms. Due to shifts in the track and the rapid intensification of the storm, real-time estimates grew from 2 to 3 billion dollars in losses late on August 12 to a peak of 50 billion dollars for a brief time as the storm appeared to be headed for the Tampa Bay area. The storm hit the resort areas of Charlotte Harbor near Punta Gorda and then went on to Orlando in the central part of the state, with early poststorm estimates converging on a damage estimate in the 28 to 31 billion dollars range. Comparable damage to central Florida had not been seen since Hurricane Donna in 1960. The Florida Commission on Hurricane Loss Projection Methodology (FCHLPM) has recognized the role of computer models in projecting losses from hurricanes. The FCHLPM established a professional team to perform onsite (confidential) audits of computer models developed by several different companies in the United States that seek to have their models approved for use in insurance rate filings in Florida. The team's members represent the fields of actuarial science, computer science, meteorology, statistics, and wind and structural engineering. An important part of the auditing process requires uncertainty and sensitivity analyses to be performed with the applicant's proprietary model. To influence future such analyses, an uncertainty and sensitivity analysis has been completed for loss projections arising from use of a Holland B parameter hurricane wind field model. Uncertainty analysis quantifies the expected percentage reduction in the uncertainty of wind speed and loss that is attributable to each of the input variables.  相似文献

The authors present an overview of the discussion and presentations that took place concerning techniques and assessment in educational and vocational guidance at the recent symposium International Perspectives on Career Development. Two topics were examined. The 1st focused on the theoretical foundations of and psychometric issues in career assessment. The 2nd focused on the practice of career assessment and the use of career measures, particularly in cultural contexts for which the measures were not originally developed.  相似文献

Une perspective de la construction sociale sert de cadre a l'analyse des controverses sur la gestion des risques qui ont été provoquées à la suite d'un incendie majeur dans une usine de recyclage de matières plastiques à Hamilton, en Ontario. En mettant l'accent sur les processus de réclamation au c?ur de l'interaction entre les représen‐tants du gouvernement, les acteurs environnementaux, les experts techniques et les résidants, il a été révélé qu'un accent trop limité aux questions d'ordre technique avait mené a l'exclusion des préoccupations fondées sur la rationalité culturelle ayant ainsi entraine un cadre d'interaction très litigieux divisant profondément. Les conséquences des conclusions empiriques de la thése de la société des risques ainsi que de la théorie sur la communication des risques sont explorées. A social construction perspective is applied in the analysis of the risk management controversies that arose in response to a large toxic fire that occurred at a Hamilton, Ontario plastics recycling facility. By focussing on the claimsmaking processes involved in the interaction of government officials, environmental movement actors, technical experts, and residents, it was found that an overly narrow focus on technical matters led to the exclusion of lay concerns based on cultural rationality, thereby resulting in a very contentious and divisive setting for interaction. Implications of the empirical findings for the risk society thesis and risk communication theory are explored.  相似文献

Foot and mouth disease (FMD) is considered by many as the most important animal disease in the world. FMD is highly contagious and outbreaks incur significant costs as affected countries are severely limited in their ability to trade. A number of trade commodities may be contaminated with FMD virus (FMDV) including animal products, for example, meat. As a member of the European Union, Great Britain (GB) has put in place a number of regulations to prevent the importation of pathogens in imported meat products. However, the illegal importation of meat provides a route by which safety controls may be circumvented and meat from FMD affected areas may be imported. This study assesses the FMD infection risk posed to the livestock population of GB from the illegal importation of meat, and estimates the major contributors to this overall risk, through the development of a quantitative risk assessment model. From model results, the total amount of illegal meat entering GB each year is estimated on average to be 11,875 tonnes. with 90% certainty that this is between 4,398 and 28,626 tonnes per year; of which between 64.5 and 565 kg are contaminated with FMDV. This flow of illegal meat results in an estimate of a frequency of FMD infection in GB livestock of 0.015 cases of infected animals per year, with 90% certainty it is between 0.0017 and 0.053. Imports from the region Near and Middle East account for 47% of this risk, and 68% of the risk is attributed to bone-in and dried de-boned products.  相似文献

Ten days after the Symbionese Liberation Army's shoot out in Los Angeles in 1974, the Cedars-Sinai Medical Center, Department of Family Child Psychiatry, Thalians Community Mental Health Center, sent a crisis team of three psychotherapists to a school in the black community. The psychotherapists used an art therapy approach with a third grade classroom of 21 black children. The team's procedure helped the children ventilate their reactions to a frightening event which occurred in their neighborhood. This paper describes the art therapy techniques which were utilized, the children's vivid pictorial and verbal expressions accompanied by the psychological aspects of their responses.  相似文献
