Estimation for the Parameters of the Pareto Distribution Under Progressive Censoring

In this article, progressive Type-II right censored sample from Pareto distribution is considered. Exact confidence region is derived for the parameters of the corresponding distribution under progressive censoring. Simulation study is performed to investigate the coverage probabilities of the proposed confidence region. Illustrative example is also given.     

Quality of College Life (QCL) of Students in Turkey: Students’ Life Satisfaction and Identification

Understanding the complexities of a students’ quality of life has become essential in order for universities to plan their spending most efficiently. This study tests a model which was used to judge the satisfaction of college life and evaluates the overall impact of quality of college life (social, academic, and service satisfaction), life satisfaction, and identification. Secondly, the study assesses the impact of a university’s academic program, social life, facilities, and services on the students’ college life quality in this sample in relation to similar studies from Turkey and other countries. The survey included 1,260 students attending a public university in northwestern Turkey. Measurement tools included the quality of college life scale (QCL), Satisfaction with college life scale, identification scale satisfaction with life scale and personal information form. The results show social satisfaction has the strongest positive impact on QCL. This study found that life satisfaction and university identification had a positive impact on a university student’s satisfaction with college life. According to survey results it is also suggested that University administrators can primarily focus on improving the social satisfaction of the students then improve facilities and services, in order to raise academic satisfaction levels.     

The Impact of Deviations from Desired Hours of Work on the Life Satisfaction of Employees

We estimate an ordinal logistic multilevel model to examine the determinants of the life satisfaction of employees in Europe. Data drawn from the European social survey reveals that deviations from desired hours of work (measured as the absolute difference between the actual and preferred weekly number of hours) reduce overall life satisfaction, but the effect is smaller in countries with higher unemployment rates. We interpret this finding as evidence that in environments where anxieties about job security are high, having a job brings about a certain level of life satisfaction regardless of the gap between the actual and preferred time spent in the labor market. We also find no statistically significant difference between male and female employees with regard to the impact of the work hours mismatch. This finding suggests that the gender differences which would have been expected in this context are already incorporated in the respondents’ subjectively determined desired hours of work. In fact, further examinations confirm that ‘desired hours’ are associated with both socio-demographic characteristics (in particular, gender) and preferences for labor market work.     

Towards a ‘Harmonious Society’? a brief case study of the post-Liberation settlement in Beijing of Uyghur intellectuals and their relations with the majority society

Currently, the construction of a ‘Harmonious Society’ is an important yet challenging official project in the People's Republic of China. Under Chinese Communist Party supervision, the government has undertaken some measures to achieve this goal. In the country's capital, Beijing, the majority society (‘social majority’) is composed of peoples considered to be Han Chinese (), but the population there also includes representatives from 55 recognised minority society groups (). Many such latter groups, especially Uyghurs and Tibetans, have long maintained distinctive cultural traditions, practices, languages, and ‘memories’ from those of the majority society – and are ‘different’ in physical appearance, customary dress and other features. Officially, however, all are ‘Chinese citizens’ (). Recently, some negative and disharmonious trends have appeared in majority-minority relations. Based on academic fieldwork research, this essay focuses on ‘Uyghur intellectuals’ in Beijing, analytically discussing their relationships with the majority society there, identifying issues and problems in those relationships, and offering informed, constructive suggestions to achieve a more ‘Harmonious Society’ in China.     

Effects of Etiological Agent and Bather Shedding of Pathogens on Interpretation of Epidemiological Data Used to Establish Recreational Water Quality Standards

The overall goal of the study reported herein was to use techniques in the field of risk assessment (specifically a state-space population dynamic model of disease transmission within recreational waters) to explore the relative significance of (1) active shedding of microorganisms from bathers themselves, and (2) the type and concentration of etiological agent on the observed heterogeneity of the incidence of illness in epidemiological studies that have been used to develop ambient water quality criteria. The etiological agent and corresponding dose ingested during recreational contact was found to significantly impact the observed incidence of illness in an epidemiological study conducted in recreational water. In addition, the observed incidence of illness was found not to necessarily reflect background concentrations of indicator organisms, but rather microorganisms shed during recreational contact. Future revisions to ambient water quality criteria should address the etiological agent, dose, and the significance of microbial shedding relative to background concentrations of pathogens and indicator organisms in addition to the incidence of illness and concentration of indicator organisms. Without a quantitative assessment of these additional variables, study findings may potentially be site specific and not representative of the health risks associated with specific indicator concentrations in all recreational waters.     

Impact of Induced Abortion on Fertility in Romania

The topic of induced abortion as a method of birth control in the formersocialist European countries has been a subject of broad debate. Legal or illegal abortion, depending on legislation restrictions, was widely used in periods when people had reduced control over their reproductive life. Romania, a former socialist country, is an interesting case to study because of the very dramatic swings in its abortion policies coupled with important changes in available contraceptive methods associated with the fall of the Soviet Empire. The study investigates the impact of induced abortion on the risks of first-, second- and third-order births in Romania during the last 35 years, using data from the Reproductive Health Survey, Romania, 2004. The legalization of abortion in 1990, after two decades of total prohibition, had an immediate effect on second- and third-order births, but it contributed less to the decrease of primo-fertility. Investigations regarding the “first and second demographic transition” that initially involved women desiring fewer children and then women modifying the timing of those births show changes in the use of abortion to achieve birth plans. The effect of abortion on fertility has decreased over time.     

Reinventing the international approaches to globalization: The Helsinki Process

Abstract

In the last ten years we have been witnessing an essential change within what we might call the ‘international approaches towards globalization’. This change is not to be considered only as being incremental but rather fundamental as it consists not merely in a strategy-oriented shift but in one of principle. From the ‘worst enemy of the poor’, globalization turned into a ‘phenomenon that we all have to take profit of’. This essay will analyze the turning point in the anti-globalization attitudes by using the study of one of the most recent and important international programmes on globalization, the Helsinki Process on Globalization and Democracy, under the aspects of the historical reform of the international approaches towards globalization.     

Partial groups ranked set sampling and mean estimation

Ranked set sampling (RSS) is an advanced sampling method which is very effective for estimating mean of the population when exact measurement of observation is difficult and/or expensive. Balanced Groups RSS (BGRSS) is one of the modification of RSS where only the lowest, the median and the largest ranked units are taken into account. Although BGRSS is advantageous and useful for some specific cases, it has strict restrictions regarding the set size which could be problematic for sampling plans. In this study, we make an improvement on BGRSS and propose a new design called Partial Groups RSS which offers a more flexible sampling plan providing the independence of the set size and sample size. Partial Groups RSS also has a cost advantage over BGRSS. We construct a Monte Carlo simulation study comparing the performance of the mean estimators of the proposed sampling design and BGRSS according to their sampling costs and mean squared errors for various type of distributions. In addition, we give a biometric data application for investigating the efficiency of Partial Groups RSS in real life applications.     

Traces of the Second Demographic Transition in Four Selected Countries in Central and Eastern Europe: Union Formation as a Demographic Manifestation

Using data from the first round of the national Gender and Generations Surveys of Russia, Romania, and Bulgaria, and from a similar survey of Hungary, which were all collected in recent years, we study rates of entry into marital and non-marital unions. We have used elements from the narrative of the Second Demographic Transition (SDT) as a vehicle to give our analysis of the data from the four countries some coherence, and find what can be traces of the SDT in these countries. The details vary by country; in particular, latter-day developments in union formation patterns did not start at the same time in all the countries, but in our assessment it began everywhere before communism fell, that is, before the societal transition to a market economy got underway in 1990.
