Abstract

Argues that strong social analysis can make a large contribution to understanding and fighting HIV/AIDS plus other infective diseases. Contends a global perspective is necessary to rethink our approach to infections as, globally, the virus seems to be strengthening, generally. Describes, through case studies, the transition of HIV outbreaks in South Africa, Eastern Europe, Russia, and Indonesia. Makes the case that HIV/AIDS is deeply tied up in fundamental structure and processes.

Abstract

Describes how HIV and AIDS are carried and spread, particularly for high‐risk groups, but adds that it is not only behavioural but also those behaviours in conjunction with others. Employs figures and tables for added explanation and emphasis. Chronicles some individual case studies showing different “risk” behaviours and types of “unsafe” practices. Makes clear that the use of varied types of education are of major importance in the fight against ignorance and nonchalance in the battle against AIDS.

Abstract

Analyses how HIV/AIDS has affected African Americans, who are acknowledged as a vulnerable racialized group, along with Puerto Ricans. Defines the term of racialized social system as a society where part of the stratification system is designed to reank people based on their racial classification. Sheds light on AIDS and ethnicity through copious use of figures and tables. Summarizes that there is little control over tehir own community economics for African Americans, legitimately, as HIV runs riot. Urges a race‐conscious approach to the HIV/AIDS epidemic.

Abstract

After a clarification of definitions important in methodological discussions, a brief history of early methodological thought in economics and political economy is presented. The development of “orthodox” methodology is traced, and the fundamental assumptions underlying neoclassical economic methodology are enumerated. Philosophical positions – both critical of and sympathetic to the orthodox assumptions – are presented. In addition, the advantages and disadvantages of various heterodox positions are surveyed. Throughout the paper, methodological justifications for the emphasis on primarily deductive, complex mathematical models in contemporary economics as practiced in the USA – especially in light of the relevance and importance of primarily verbal, interpretive methodologies in the realm of applied and policy‐oriented economics – are examined.

Abstract

Purpose

The purpose of this paper is to evaluate the fire resistance of an innovative carbon-reinforced PEKK composite for aeronautical applications. To this end, thermal degradation analysis under inert and oxidative atmosphere is carried out. Moreover, a linear model fitting approach is compared to a generally used isoconversional method to validate its reliability for kinetic triplet estimation.

Design/methodology/approach

Thermogravimetric analysis carried out under inert and oxidative atmospheres, between 25 and 1000°C for three different heating rates (5, 15, 25°C/min), followed by a qualitative SEM observation of the samples before and after thermal treatment. After the reaction identification by TG/DTG curves, an isoconversional analysis is carried out to estimate the activation energy as a function of the reaction conversion rate. For the identified reactions, the kinetic triplet is estimated by different methods and the results are compared to evaluate their reliability.

Findings

In inert case, one global reaction, observed between 500-700°C, seems able to describe the degradation of carbon-PEKK resin. Under oxidative atmosphere, three main reactions are identified, besides the resin degradation, the other two are attributed to char and fiber oxidation. Good agreement achieved between isoconversional and linear model fitting methods in activation energy calculation. The achieved results demonstrate the high thermal resistance of PEKK associated with the ether and ketone bonds between the three aromatic groups of its monomer.

Originality/value

This paper provides a possible degradation model useful for numerical implementation in CFD calculations for aircraft components design, when exposed to high temperatures and fire conditions.

Abstract

This paper is an initial attempt to discuss the American institutionalist movement as it changed and developed after 1945. Institutionalism in the inter-war period was a relatively coherent movement held together by a set of general methodological, theoretical, and ideological commitments (Rutherford, 2011). Although institutionalism always had its critics, it came under increased attack in the 1940s, and faced challenges from Keynesian economics, a revived neoclassicism, econometrics, and from new methodological approaches derived from various versions of positivism. The institutionalist response to these criticisms, and particularly the criticism that institutionalism “lacked theory,” is to be found in a variety of attempts to redefine institutionalism in new theoretical or methodological terms. Perhaps the most important of these is to be found in Clarence Ayres’ The Theory of Economic Progress (1944), although there were many others. These developments were accompanied by a significant amount of debate, disagreement, and uncertainty over future directions. Some of this is reflected in the early history of The Association for Evolutionary Economics.
