This paper tackles the practical application of statistical tools. Chemical development is a rich area for collaboration between statisticians and chemists, but most statisticians encounter difficulties in promoting the tools to this client group. This paper, presented from a chemist's perspective, is intended to help bridge the gap between the two professions. The paper explores differences in uptake and attitudes towards adopting these techniques and suggests what has hindered or helped the process of effective application of experimental design.

In the sociology of science, the historical analysis of the rise of seventeenth-century experimental science has been dominated by the research of Robert Merton, who argued that Protestant asceticism paved the way for scientific world-views. Merton was criticized by L.S. Feuer who claimed that science was in fact the outcome of hedonism not asceticism. This article supports the Merton thesis on the basis of a note on the historical development of anatomical dissections with special reference to public dissections in Holland m the seventeenth century. The principal difficulty for both Merton and Feuer is that scientific medicine in pre-modern societies was not differentiated from either religion or law. The anatomy lesson was in fact a juridical and moral drama.  相似文献

Recognition of ‘Farmer's Rights’ is an attempt by developing countries to evolve a counterclaim to breeders' Intellectual Property Rights (IPRs) promoted under the TRIPs Agreement of the WTO. India is one of the first countries to have granted rights to both breeders and farmers under the Protection of Plant Varieties and Farmers' Rights Act, 2001. This multiple rights system aims to distribute rights equitably, but may pose the threat of an ‘anticommons tragedy’ i.e. too many parties independently possessing the right to exclude others from utilising a resource. If under‐utilisation of plant genetic resources results, the Act will have negative consequences for sustaining crop productivity and for the welfare of the very farming communities it seeks to compensate.  相似文献

Suggestions for enhancements to socio-technical systems (STS) theory are offered based on a multiyear development process. First, researchers engaged in an iterative process of working with socio-technical systems (STS) and non-STS practitioners of organizational design to operationalize STS theory. Second, the operationalized theory was validated using an 86-company survey. Third, the operationalized theory was field-tested to discover its usability for practitioners addressing real-world organizational design problems.  相似文献

Plant genetic resources constitute the biological basis for plant breeding and future agricultural development. Their transfer from developing to developed countries over centuries has sometimes been viewed as an example of exploitation, if not ‘biopiracy’. Modern gene flows are different in character and magnitude from historic exchanges, however. This article examines current patterns and finds that developing countries are major net recipients of germplasm samples from CGIAR centres, particularly if ‘improved materials’ are considered. Potentially problematic, intellectual property rights do not currently present major barriers to the availability and use of genetic resources by developing countries. Proposals to restrict flows and redress perceived injustices may reduce the benefits accruing at present to developing countries from germplasm exchanges.  相似文献

Abstract

The recent deaths of Michael Brown, Trayvon Martin, and other Black males have generated new civil rights urgencies in Black communities and spirited academic discourses in higher education regarding the educational and social plight of Black males in America. Connecting the deaths of Black males to our lived experiences in the academy, we use a text messaging performative writing style to demonstrate how Black males are not only gunned down in the streets of America by police but also are metaphorically gunned down in the academy. That is to say, white colleagues and students attempt to use what we call the bullet of rejection, the bullet of silencing, and the bullet of disrespect to destroy us and our academic agenda. We conclude with a call to action for teacher education programs as a way to deepen their understanding of the racialized experiences of Black males in the academy and Black males in America.  相似文献

Coverage and response rate challenges facing telephone and internet surveys have encouraged scientists to reconsider mail data collection methods. Although response rates to telephone surveys have declined sharply in the last 20 years, it is unclear how response rates to mail have fared during this time. This study analyzes 179 mail-back surveys of visitors to US National Parks from 1988 to 2007, which used virtually the same administration procedures throughout the period. Results show that response rates, based on only those who initially agreed to return a questionnaire, have remained at a high level with a 76% average while the number of questions and pages steadily increased. Despite this rise in response burden, rates have declined only moderately from about 80% in the late 1980s to about 70% more recently. The roles of additional contacts and survey salience in maintaining high response rates are examined. Results suggest that mail-back surveys for obtaining information from quasi-general public populations remain an effective data collection procedure.  相似文献

Designing a professional development system for parent educators requires weaving together multiple pieces from within the network of organizations providing parenting education. North Carolina examined how to build a system using the influence of evidence-based programs as well as professional credentialing for parenting educators. A system built with professionals who understand sound parenting practices and networked together to use best practices with parents is critical to support families and prevent child abuse.  相似文献
