CONTROL: the extractive ecology of corn monoculture

This article tells the history of the industrial and biotechnological development of large-scale corn agriculture, from a new materialist perspective. Addressing the large-scale economy of industrial food production as a form of more-than-human configuration, it demonstrates how corn has been made into a quintessential commodity and factor of production for a consumption-based economy. Set within discourses around the climate crisis, this account critically assesses the Anthropocene and its advocacy for human accountability in regards to the exploitation of nonhuman matters. I ask: who is the Anthropos? How does it/he/she meet with its domesticated subjects, or rather makes them into domesticable materials? Telling the history of corn monoculture from a new materialist standpoint exposes this industry’s distribution of agency, power and control across a diversity of human and nonhuman actors. This is at the centre of this article’s three sections: (1) an argument for inscribing extractivism within new materialist literature, (2) an account of the industrialization of corn monoculture, exposing the industry’s main mechanisms and economic endeavours, as well as its ramifications with a biopolitics of invasion and (3) the biotechnological development of the industry and its shifts from a biopolitics of vegetal matter to an informational extractivism and a necropolitics of killable life. Thus I argue that if the industry of corn monoculture belongs to a broader network of detrimental industries characteristic of the Anthropocene, the geological Anthropos is not to be understood as synonymous with the human species, but as a very restrictive ecology of humans and nonhumans, including corporate, industrial, technoscientific and extractive actors. As such, the article emphasizes the moral necessity of rupturing with the narrative of the Anthropocene, a discourse better suited for supporting existing mechanisms of domination and exploitation constitutive of the economy of climate change.     

Open spaces for dialogue promoting mental health as a social work education methodology

ABSTRACT

The authors discuss service user involvement as a key approach regarding training of social workers. In many European Union countries this is a stable practice with a lengthy tradition in research and application. However, in Poland it is almost entirely absent and marginalized. This article presents the results of a participatory action research project conducted at the Institute of Sociology of the Jagiellonian University in Krakow, the objective of which was to identify and critically analyze the key substantive and formal aspects of training of social workers with the participation of individuals with experience of mental illness. This research project adopted an open approach to cognizing reality based on qualitative co-participatory methods. In the conclusion, the authors emphasize that the fundamental criterion for the success of this particular form of training is voluntary and differentiated participation of students—both in the role of people sharing their own experience and as learners—as well as shaping a culture of open dialogue, educational alliances of recognition and recovery, the foundation of which is axiological experience.     

On concurrence of several linear regressions and applications to problems of enzyme kinetics

In comparing several regressions E(y_ij) =α_i + β_ix_ij i = 1, 2, ..., k, j = 1,2, ..., n_i, researchers are generally interested in the following five problems: whether they have (1) equal slope, (2) equal intercept, (3) coincidence, (4) common intersection on X-axis, and (5) common intersection on (X,Y) - plane. Problems (1) - (3) can be put into the framework of the general linear hypothesis and the F-test can be used. However, problems (4) and (5) cannot be put into the general linear hypothesis because they are ratios of parameters. Hence, in this paper we consider the generalized likelihood ratio test for hypothesis testing. An application to an enzyme kinetics problem in Aniline Metabolism is demonstrated     

Sample size determinations when two binomial proportions are very small

Sample size determination for testing the hypothesis of equality of proportions with a specified type I and type I1 error probabilitiesis of ten based on normal approximation to the binomial distribution. When the proportionsinvolved are very small, the exact distribution of the test statistic may not follow the assumed distribution. Consequently, the sample size determined by the test statistic may not result in the sespecifiederror probabilities. In this paper the author proposes a square root formula and compares it with several existing sample size approximation methods. It is found that with small proportion (p≦.01) the squar eroot formula provides the closest approximation to the exact sample sizes which attain a specified type I and type II error probabilities. Thes quare root formula is simple inform and has the advantage that equal differencesare equally detectable.
