The Evolution of Feminism: Comparison of Adaptation and By-Product Concepts

The aspiration of an ideal social structure includes the ambition of construction of a society that does not discriminate on the basis of gender. The development of feminist thought is an endeavor for evolutionary changes within the prevailing patriarchal society. This article exemplifies the development and changes in the feminist movement due to internal pressures, external politics, and ideological changes, by highlighting the oppression of women and the movement's chief accomplishments, and strives to explain this evolution from the standpoint of two alternative justifications, an adaptationist and by-product influence. It elucidates underlying aspects of the movement and the prerequisites for it to flourish and become a multifaceted, global phenomenon.     

The propagation of lean thinking in SMEs

Abstract

Small and Medium-sized Enterprises (SMEs) play a pivotal role in economic growth, industrial output, and employment creation. However, SMEs are often ignored by researchers as far as the adoption of lean is concerned in comparison to Large Enterprises (LEs). Therefore, the literature regarding lean implementation in SMEs is not conspicuous, and many SMEs have only a limited understanding and awareness of lean. This paper offers a comprehensive literature review with a focus on the implementation of lean in SMEs and explores the applicability of lean thinking in such environments. An attempt is made to provide an analysis of lean practices that have been applied in SMEs and critical success factors for lean transformation in SMEs. It also contributes to the field of lean implementation research by proposing a framework for lean in SMEs and identifies the scope of future research.     

垄断竞争和最优的产品多样化

比较分析在垄断力量存在时市场均衡及最优资源分配的各种情形就会发现,垄断力量和市场扭曲的方向并没有显著的关系,在弹性不变的效用函数情形下,市场解能达到有约束的帕累托最优,而与弹性数值无关。对于可变弹性,市场解对最优的偏离是不确定的。具有非对称的需求和非对称的成本的条件下,市场偏离无弹性和高成本的商品。     

On Modes of Economic Governance

I consider transactions involving asymmetric prisoners’ dilemmas between pairs of players randomly selected from two large populations. Games are played repeatedly, but information about cheating is not adequate to sustain cooperation, and there is no official legal system of contract enforcement. I examine how profit–maximizing private intermediation can supply the information and enforcement. I obtain conditions under which private governance can improve upon no governance, and examine why it fails to achieve social optimality.     

On the adoption of lean manufacturing principles in process industries

Traditionally, the lean paradigm has been applied to discrete manufacturing of items that can be easily put together and taken apart. The process industry, on the other hand, transforms raw materials into cohesive units that are basically blended into a final product with parts that cannot be disassembled and then reassembled. The current lean literature provides numerous commendable examples of theory and practices of lean principles in discrete manufacturing. However, its application in process industry is limited. Furthermore, there is no systematic accounting of the lean literature in this sector, which may have contributed to lesser awareness in the industry. This paper provides a state-of-the-art review of lean manufacturing literature with respect to its applications in process industry. It contributes to the classification of literature in a manner which helps to identify strategies suitable for the adoption of lean concepts in process industry. The paper seeks to synthesise the literature with an emphasis on identifying the scope for lean in process industry and associated benefits. The review also presents an analysis of the lean tools and techniques that have been applied or have potential application in the process industry and the challenges to implement lean. We believe that such a comprehensive review will not only facilitate the adoption of lean in process industry but will also provide agenda for further research by exposing voids in the knowledge base.     

Impact of Road Traffic Deaths on Expected Years of Life Lost and Reduction in Life Expectancy in Brazil

The road traffic crash burden is significant in Brazil; calculating years of life lost and life expectancy reduction quantifies the burden of road traffic deaths to enable prioritization of this issue. Years of life lost and reduction in life expectancy were calculated using 2008 population/crash data from Brazil’s ministries of health and transport. The potential for reduction in crash mortality was calculated for hypothetical scenarios reducing death rates to those of the best-performing region and age category. In Brazil, road traffic deaths reduce the at-birth life expectancy by 0.8 years for males and by 0.2 years for females. Many years of life lost for men and woman could be averted—270,733 and 123,986, respectively—if all rates matched those of the lowest-risk region and age category. This study further characterizes the burden of motor vehicle deaths in Brazil and quantifies the potential health benefits of policies/interventions that reduce road traffic death rates to those of the best-performing subpopulations.
