  • Trends in needing help with such activities as housework or shopping may be due to changes in the physical abilities of the older population, but they may also be related to the availability of help in the house, either familial or paid, the availability of appliances, and the accessibility of transportation (1, 12). However, causes of trends in IADL functioning have not been apportioned to reasons residing in the person and reasons outside the person. The trends in what is termed ADL disability have not been nearly as consistent as those in IADL disability (31).

  • The numerical stability of the Levinson-Durbin algorithm for solving the Yule-Walker equations with a positive-definite symmetric Toeplitz matrix is studied. Arguments based on the analytic results of an error analysis for fixed-point and floating-point arithmetics show that the algorithm is stable and in fact comparable to the Cholesky algorithm. Conflicting evidence on the accuracy performance of the algorithm is explained by demonstrating that the underlying Toeplitz matrix is typically ill-conditioned in most applications....

  • The available evidence suggests that they are not. Every five years, the Census Bureau conducts its nationwide Survey of Business Owners.

The figure for men-owned firms was 6.3 percent In public perception, the $1 million threshold has become a sort of magic number.

  • Throughout the late-1940s and 1950s, the top marginal tax rate was typically above 90%; today it is 35%. Additionally, the top capital gains tax rate was 25% in the 1950s and 1960s, 35% in the 1970s; today it is 15%. The real GDP growth rate averaged 4.2% and real per capita GDP increased annually by 2.4% in the 1950s. In the 2000s, the average real GDP growth rate was 1.7% and real per capita GDP increased annually by less than 1%. This analysis finds no conclusive evidence, however, to substantiate a clear relationship between the 65-year reduction in the top...

  • Social capital refers to relationships of trust and mutuality that can be mobilized to achieve instrumental ends. Social capital is the relationship glue through which individuals, families and social networks navigate economic opportunity, social conflict and various institutions. While social capital is not just built through place-based networks, locality plays a role, particularly in many economically disadvantaged areas.

  • I have accepted no statement of fact, however generally made, until I was fully persuaded from my own personal investigation that what I heard was really a fact and not a rumour. Wherever I have ventured upon conclusions, I claim for them neither infallibility nor originality. They are offered frankly as my own latest and clearest thoughts upon the various subjects discussed. If any man can give me better evidence for the error of my conclusions than I have for the truth of them I am prepared to go with him, and gladly, as far as he can prove his way. And I have offered...

  • Progress towards gender equality is a critical issue for us. …..First we will adopt measures to restore those rights to our women and girls that they were denied because of the segregationist policies of the Taliban and the threat to their personal security during periods of conflict. To support this, we will need to create women's specific opportunities that will allow them to catch up with men and boys.

  • Medicine without statistics is quackery; statistics without medicine is numerology. Perhaps this is the main reason why clinicians should care about statistics. Statistics in medicine began in the early nineteenth century (it was called “the numerical method” then) and its debut involved disproving the most common and widely accepted medical treatment for millennia: bleeding. From ancient Rome until 1900, all physicians – from Galen to Avicenna to Benjamin Rush – strongly and clearly advocated bleeding as the treatment for most medical illnesses.

  • A cascade of events (signal-transduction), mainly seen in rat cardiac myocytes and renal cells, is thought to occur after ouabain interaction with a minor fraction of Na + /K + -ATPase. Ahigher intracellularNa + concentration followed sodium pump inhibition by ouabain with a subsequent gradual increase or oscillations in intracellular Ca 2+ con-centration. Whether this increase in intracellular Ca 2+ concentration is part of the cascade, a result of the cascadeor a totally independent phenomenon are conflicting interpre-tations that are discussed. ...

  • Living arrangements, particularly overcrowded conditions and a lack of privacy, have been associated with conflict within families. Although abuse can occur when the abuser and the older person suffering abuse live apart, the older person is more at risk when living with the caregiver. The early theories on the subject also sought to associate dependency with increased risk of abuse.

  • Globalization has perhaps been the notion most widely used and debated by the social sciences in the last decade of the twentieth century and in the first years of the twenty-first. Subject to diverse and sometimes conflicting interpretations, the concept has also been the target—as shown in Chap. 1—of harsh criticisms from authors who have contested its real meaningfulness and extent.

  • This paper considers the problem of policy evaluation in a modern society with heterogeneous agents and diverse groups with conflicting interests. Several different approaches to the policy evaluation problem are compared including the approach adopted in modern welfare economics, the classical representative agent approach adopted in macroecononomics and the microeconomic treatment effect approach. A new approach to the policyevaluationproblemis developed and applied that combines and extends the best features of these earlier approaches.

  • To stress the salience and urgency of the national situation as dictated by contemporary terrorism and to underscore the need for behavioral and social science understandings of that situation are to pronounce the self-evident. Terrorism, already recognized by some as the looming form of international conflict in the late twentieth century, moved dramatically to center stage on September 11, 2001, and promises to occupy national attention for decades.
