Addiction in Action

As human action, drinking alcohol or smoking cigarettes, for instance, are phenomena that are familiar to most people. We recognise when people use drugs or gamble whether that happens in the television or around us. Sometimes we call these actions addictions. Addictive actions are actions that puzzle us. This puzzlement has raised different kinds of views on addiction that describe the phenomenon in different ways. The proponents of the views pick features that they consider to be sufficient in capturing the phenomenon. The disease view emphasises that addicted individuals are not in control over their own actions, whereas the choice view highlights addicted individuals’ capacity to act according to their own preferences. Some see addiction as a defect of will and addictive action is a manifestation of that. Sometimes they all insist on referring to the same group of people and describing the same actions with seemingly contradictory terms. What happens when an addicted individual acts in accordance with his addiction? This thesis also tries to answer this question and make this kind of action and agency understandable. By showing that these three common views fall short of capturing the phenomenon, I will provide characteristics that jointly suffice for something to be labelled addiction, but which are not, however, individually necessary (or sufficient) for addiction. Those characteristics are strong desire, myopia, biased decision-making, and weakness of will. Furthermore, they should be understood in the framework of diachronic, active agency. They contribute to a view on addictive action that consists of different kinds of actions. Acknowledging the variety of nuanced human action, the understanding of addictive action is increased and this may also be utilised in addiction-related policies and treatment. The emphasis of my study lies specifically on understanding addiction as action by the means of analytical philosophy.

Action of gibberellic acid (GA3) on dormancy and activity of alpha-amylase in rice seeds

To evaluate the effectiveness of gibberellic acid (GA3) in breaking rice seed dormancy and the use of alpha-amylase enzyme activity as an indicator of the dormancy level, seed from the intensively dormant irrigated cultivar Urucuia were used. The seeds were submitted to a pre-drying process in a forced air circulation chamber under 40ºC during 7 days and submersed in 30 mL of GA3 solution under 0, 10, 30 and 60 mg/L H2O concentrations, during 2, 24 and 36 hours. After the treatments, the alpha-amylase activity was determined by using the polyacrilamide electrophoresis and spectrophotometry. At the same time, the germination test was made. The results indicated a gain in germination and in alpha-amylase activity in higher concentrations and soaking time of seeds in GA3. These observations support the conclusion that soaking seed in 60 mg GA3/L during 36 hours can be used as a quick and efficient treatment in breaking rice seed dormancy and is equivalent to the forced air circulation chamber at 40ºC during 7 days. The alpha-amylase enzyme activity proved to be as an efficient marker of the seeds dormancy level.

A framework to understand human action

This paper consists in an analysis of two explanatory models of human behaviour which play a prominent role in the contemporary literature on human action. The first model - the causalist - aims at explaining action in terms of causes and general laws. The second model - the intentionalist - explains human action in terms of intentions and practical syllogism. The difficulties of both models are presented and in the last part of the essay we propose one alternative model, based on the notion of retroduction.
