During the last two decades the role of quantitative genetics in evolutionary theory has expanded considerably. Quantitative genetic-based models addressing long term phenotypic evolution, evolution in multiple environments (phenotypic plasticity) and evolution of ontogenies (developmental trajectories) have been proposed. Yet, the mathematical foundations of quantitative genetics were laid with a very different set of problems in mind (mostly the prediction of short term responses to artificial selection), and at a time in which any details of the genetic machinery were virtually (...) unknown. In this paper we discuss what a model is in population biology, and what kind of model we need in order to address the complexities of phenotypic evolution. We review the assumptions of quantitative genetics and its most recent accomplishments, together with the limitations that such assumptions impose on the modelling of some aspects of phenotypic evolution. We also discuss three alternative appr oaches to the theoretical description of evolutionary trajectories (nonlinear dynamics, complexity theory and optimization theory), and their respective advantages and limitations. We conclude by calling for a new theoretical synthesis, including quantitative genetics and not necessarily limited to the other approaches here discussed. (shrink)

American agricultural history, literature, and thought reveal historical circumstances that have often been unfavorable to the development of a sustainable agriculture in the United States. Further critical examination of these historical and cultural roots reveals that sustainable agriculture is an evolving concept that can be traced to the tradition of agrarian idealism, scientific and organic agriculture, and the recent history of ecological ideas, beginning with the “Dust Bowl” and extending to the present.

Collection of essays on the connection between medicine and literature and how novelists and physicians are both, in a sense, diagnosticians; the book focuses, in particular, on Walker Percy, a writer who had trained as a pathologist.

An exploration of the nexus between ecology, evolutionary biology and molecular biology, via the concept of phenotypic plasticity.

Pregnant people are often listed among groups that have been excluded from research on the basis of perceived vulnerability, to the detriment of the entire class. Lack of research among pregnant pe...

Job motivation remains an area of concern among researchers due to the rising issues of poor or lack of motivation among workers. This refers to one’s personal will or drives to perform a task at work. Meanwhile, job satisfaction refers to an employee’s sense of fulfillment with his or her work experience. Therefore, the current study utilized the descriptive- correlational research design to investigate the impact of job motivation on the job satisfaction of accountants. To gather essential data and achieve (...) the objectives of the study, Multidimensional Work Motivational Scale (MWMS) and Minnesota Satisfaction Questionnaire (MSQ) were administered to the target respondents. The collected data were then analyzed using a Multiple Regression Analysis; findings revealed that job motivation has a significant impact on the job satisfaction of accountants. Additionally, the results of this study were carefully evaluated and discussed, and recommendations were made to benefit the stakeholders of the study and contribute to the existing body of knowledge.

In our recent article, together with more than 60 of our colleagues, we outlined a proposal for drug policy reform consisting of four specific yet interrelated strategies: (1) de jure decriminalization of all psychoactive substances currently deemed illicit for personal use or possession (so-called “recreational” drugs), accompanied by harm reduction policies and initiatives akin to the Portugal model; (2) expunging criminal convictions for nonviolent offenses pertaining to the use or possession of small quantities of such drugs (and releasing those serving (...) time for these offenses), while delivering retroactive ameliorative relief; (3) the ultimate legalization and careful regulation of currently illicit drugs; and (4) the delivery of a new “Marshall Plan” focused on community-building initiatives, expanded harm reduction programs, and social and health care support efforts (Earp et al. 2021). We were gratified to see so many thoughtful commentaries on our proposal, and we respond to them in part in this reply. (shrink)

L'A. étudie le récit d'Eunapius concernant le règne d'Arcadius à partir de la mort de Théodose en 395 jusqu'en 404.

_Black Intellectual Thought in Education_ celebrates the exceptional academic contributions of African-American education scholars Anna Julia Cooper, Carter G. Woodson, and Alain Leroy Locke to the causes of social science, education, and democracy in America. By focusing on the lives and projects of these three figures specifically, it offers a powerful counter-narrative to the dominant, established discourse in education and critical social theory--helping to better serve the population that critical theory seeks to advocate. Rather than attempting to "rescue" a few (...) African American scholars from obscurity or marginalization, this powerful volume instead highlights ideas that must be probed and critically examined in order to deal with prevailing contemporary educational issues. Cooper, Woodson, and Locke’s history of engagement with race, democracy, education, gender and life is a dynamic, demanding, and authentic narrative for those engaged with these important issues.
