Design Guide for Concrete-filled Double Skin Steel Tubular Structures

Design Guide for Concrete-filled Double Skin Steel Tubular Structures

This is the first design guide on concrete filled double skin steel tubular (CFDST) structures. It addresses in particular CFDST structures with plain concrete sandwiched between circular hollow sections and provides the relevant calculation methods and construction provisions for CFDST structures. These inherit the advantages of conventional concrete-filled steel tubular (CFST) structures including high strength good ductility and durability high fire resistance and favourable constructability. Moreover because of their unique sectional configuration CFDST structures have been proved to possess lighter weight higher bending stiffness and better cyclic performance than conventional CFST. Consequently CFDST can offer reduced concrete consumption and construction costs. This design guide is for engineers designing electrical grid infrastructures wind power towers bridge piers and other structures requiring light self-weight high bending stiffness and high bearing capacity.

Stereotyping as Inductive Hypothesis Testing

Stereotyping as Inductive Hypothesis Testing

Traditional social hypotheses have a built-in tendency to verify themselves and so involuntarily resist attempts at stereotype change or correction. This is the insight demonstrated and discussed as the start point for an alternative approach to the problem of stereotyping and hypothesis testing. Stereotyping as Inductive Hypothesis Testing explicates the proposition that many stereotypes originate not so much in individual brains but in the stimulus environment that interacts with and constitutes the social individual. This cognitive-ecological approach is then used to analyse the different aspects of language sign systems and communication that can implicitly govern hypothesis testing procedures and lead to circular or reinforcing outcomes. The authors describe factors in tests such as judgment memory and expectation and go on to suggest viable ecological learning approaches to them. An original research project based on a classroom situation is used to demonstrate and verify findings. The cognitive-ecological approach is then contextualised in relation to both the traditional approaches it can replace and the contemporary statistical sampling practices it can improve. Written with a profound understanding of the link between theoretical rigour and good empirical research practice this monograph will be invaluable to anyone with an interest in stereotyping or who wishes to enhance the reliability and self-awareness of their research methods.

The Theory of Economic Development

The Theory of Economic Development

Joseph Schumpeter (1883–1950) is one of the most fascinating and influential economists of the twentieth century renowned for his brilliant and unorthodox insights into the nature of capitalism. His students include leading economists such as Paul Samuelson Robert Solow and the former chairman of the Federal Reserve Alan Greenspan. The Theory of Economic Development is one of Schumpeter's most important books and the one that made him famous. He poses a fundamental question: why does economic development proceed cyclically rather than evenly? Turning prevailing economic theory which approached economics as equilibrium on its head Schumpeter argues it is because economics is constantly transformed by its own internal forces. These forces are the 'circular flow' of economic life; economic development characterised by disruption and innovation; and finally the levers that push and pull capitalism including credit profit and interest. These are all manifested in the ‘business cycle’ one of Schumpeter's major contributions to understanding economics and now a perennial feature of virtually all economics and business curricula. He is also the first economist to place the entrepreneur at the heart of capitalism anticipating subsequent fascination with entrepreneurship in popular business and management writing. Schumpeter also lays the groundwork for his subsequent highly influential idea of the 'creative destruction' characteristic of radical and rapid economic change. The Theory of Economic Development remains a vital magisterial account of economics and the nature of capitalism whose many insights remain highly relevant today. This Routledge Classics edition includes a new Introduction by Richard Swedberg.

Immigrants and Social WorkThinking Beyond the Borders of the United States

Immigrants and Social WorkThinking Beyond the Borders of the United States

Explore an understudied but vital aspect of the immigration experience!Until now the American social work literature on immigration has emphasized one part of the migration process—the experiences of immigrants in this country. Country-of-origin experiences that lead to emigration have received limited attention. Immigrants and Social Work: Thinking Beyond the Borders of the United States expands the focus of the literature drawing clear connections between immigrants’ situations in their countries of origin and how they adapt to their new country.This book presents a two (or more)country perspective on immigration looking at migration as a process that requires an understanding of phenomena that occur in immigrants’ country of origin and that impact their lives in the United States. It also looks at immigrants’ back-and-forth movements between their home and new countries and examines the immigration process when it involves movement to a third or fourth country—or as in the case of the Armenian diaspora a return to the home country after years of settlement in a new land.To provide immigrants with effective social services it is essential to understand the situations that prompted them to uproot their lives and start over in a new country. Immigrants and Social Work: Thinking Beyond the Borders of the United States provides an unflinching look at many of these country-of-origin issues examining: mental health issues that result from the traumatic experiences of undocumented Mexican immigrants the essential link between international social work and social work with immigrants and refugees in the United States cross-national collaboration between educators in the United States and Armenia that is helping to provide vital services to Armenian refugees the phenomenon of return migration the migration experiences of women living in towns along the United States/Mexico border culturally competent mental health service delivery for Chinese immigrants circular migration between Puerto Rico and the United States the challenges facing impoverished Dominican immigrants to the United States—and a look at the relationship between the two countries’ policies regarding migrationImmigrants and Social Work: Thinking Beyond the Borders of the United States is important reading for social work professionals who serve immigrant populations. It is also an ideal ancillary text for courses in international social work family policy social work with immigrants and refugees child welfare and social work practice with families as well as any social work course that covers Chinese Mexican Armenian Puerto Rican or Dominican immigrant populations.
