Birth Death

Sufficient conditions are presented for the limiting normality of sequences of discrete random variables possessing unimodal distributions. The conditions are applied to obtain normal approximations directly for the hypergeometric distribution and the stationary distribution of a special birth-death process.

The article focuses on examining the influence of fluctuations in annual precipitation amount on the quality of surface waters. Water quality was estimated with data on BOD, COD and phosphate–ion concentration within five selected regions of Ukraine. Analysis of the precipitation data (1991 – 2010) showed different regional trends. Using the statistics, determination of the interconnection between precipitation amount and water resources quality were done. The obtained regularities and associated uncertainties can be used for prediction of changes in water resource quality and as a guide for future adaptation to possible climate change.

The Difference

Experiencing high fertility and declining mortality levels, the developing countries are today faced with the problem of relatively high rates of natural increase in their populations. This pace of growth in population, influenced by high fertility levels, impedes the overall development planning. As pointed out in a document prepared by the Planning Commission of Pakistan, 'A vicious circle is set in motion in which high fertility and socio-economic stagnation breed upon each other' [5]. In the developing countries, development programmes including birth control programmes are in operation. The sustained high fertility levels, therefore, call for more insights into the mechanisms operating in the society and influencing fertility. Studies of fertility behaviour are conducted at both micro and macro levels. The difference between micro and macro is a matter of emphasis rather than one of kind, and both approaches are concerned with each level of social aggregation. Macrolevel studies describe the level and pattern of change resulting from the ongoing socio-econornic development in the society as a whole and do not explain variations in fertility at the household level [12]. However, development programmes, which are implemented at aggregate levels defined by geographical boundaries, influence the population in terms of socio-economic status and fertility behaviour. There are many factors which affect human fertility individually or collectively. Attempts have been made to identify these factors, and conceptual frameworks have been developed to explain the causal hypotheses. In this context mention may be made of the demographic transition theory, which is often applied to study fertility behaviour.

Film Comedy

This is a book about the intersection of humor, history, and culture. It explores how film comedy, one of the world’s most popular movie genres, reflects the values and beliefs of those who enjoy its many forms, its most enduring characters and stories, its most entertaining routines and funniest jokes. What people laugh at in Europe, Africa, or the Far East reveals important truths about their differences and common bonds. By investigating their traditions of humor, by paying close attention to the kinds of comedy that cross national boundaries and what gets lost in translation, this study leads us to a deeper understanding of each other and ourselves. Section One begins with a survey of the theories and research that best explain how humor works. It clarifies the varieties of comic forms and styles, identifies the world’s most archetypal figures of fun, and traces the history of mirth from earliest times to today. It also examines the techniques and aesthetics of film comedy: how movies use the world’s rich repertoire of amusing stories, gags, and wit to make us laugh and think. Section Two offers a close look at national and regional trends. It applies the concepts set forth earlier to specific films across a broad spectrum of sub-genres, historical eras, and cultural contexts, providing an insightful comparative study of the world’s great traditions of film comedy.

Abstract Background A persistent research finding in Finland and elsewhere has been variation in medical practices both between and within countries. Variation seems to exist especially if medical decision making involves discretion and the best treatment cannot be identified unambiguously. This is true for hysterectomy when performed for benign causes. The aim of the current study was to investigate regional trends in hysterectomy in Finland and the potential convergence of rates over time. Methods We used hospital discharge register data on hysterectomies performed, diagnoses, age, and region of residence to examine hospital discharges for women undergoing hysterectomy in 2001–2018 among total female population aged 25 years or older in Finland. We examined hysterectomy rates among biannual cohorts by indication, calculated age-standardised rates and used multilevel models to analyse potential convergence over time. Results Altogether 131,695 hysterectomies were performed in Finland 2001–2018. We found a decreasing trend, with the age-adjusted overall hysterectomy rate decreasing from 553/100,000 person years in 2001–2002 to 289/100,000 py in 2017–2018. Large but converging regional differences were found. The correlations between hospital district intercepts and slopes in time ranged from − 0.71 to − 0.97 (p < 0.001) suggesting diminishing variation. Conclusions Our findings demonstrate that change in hysterectomy practices and more uniformity across regions are achievable goals. Regional variation still exists suggesting differences in medical practices.
