Sociologia ed epistemologia delle frontiere disciplinari: un percorso fra Bourdieu e Passeron
No full textBourdieu and Passeron are strictly linked with the French epistemological tradition named Historical Epistemology. In this paper, the author reconstructs the application of epistemological regionalism in sociology. The concept/theory of epistemological regionalism was formulated first by Bachelard and then developed by Canguilhem. It was then employed by Bourdieu and Passeron in order to describe the characteristics of sociological rationalism. After the separation from Bourdieu, Passeron developed the notion of style of reasoning (inspired by Hacking and Crombie theories). A specific focus in the article/paper is devoted to the topic of disciplinary boundaries in social science and humanities. The aim is to give a coherent reconstruction of the epistemological and sociological assumption of Bourdieu and Passeron about the disciplinary divisions on the field of social sciences and humanities
Capillary Drop Penetration Method to Characterize the Liquid Wetting of Powders
No full textWe present a method to characterize the wettability of powders, based on the penetration dynamics of a sessile drop deposited on a slightly compressed powder bed. First, we show that a direct comparison of the wetting properties of different liquids is possible without having to solve the three-dimensional liquid penetration problem, by considering the appropriate dimensionless variables. We show that the contact area between the sessile drop and the powder bed remains constant during the penetration process and demonstrate that, as a result, the evolution of the dimensionless penetration volume is given by a universal function of the dimensionless time, with no dimensionless parameters. Then, using a reference liquid that completely wets the powder it is possible to obtain an effective contact angle for a test liquid of interest, independent of other properties of the powder bed, such as permeability and characteristic pore size. We apply the proposed method to estimate the contact angle of water with different powder blends, by using silicone oil as the reference liquid. Finally, to highlight the potential of the proposed method to characterize pharmaceutical powders we consider a blend of Lactose, Acetaminophen and a small amount of lubricant (Magnesium Stearate). The proposed method adequately captures a large increase in hydrophobicity that results from exposing the blend to excessive mixing, a well known effect in pharmaceutical industry.Peer reviewe

Toward predicting tensile strength of pharmaceutical tablets by ultrasound measurement in continuous manufacturing
No full textAn ultrasound measurement system was employed as a non-destructive method to evaluate its reliability in predicting the tensile strength of tablets and investigate the benefits of incorporating it in a continuous line, manufacturing solid dosage forms. Tablets containing lactose, acetaminophen, and magnesium stearate were manufactured continuously and in batches. The effect of two processing parameters, compaction force and level of shear strain were examined. Young's modulus and tensile strength of tablets were obtained by ultrasound and diametrical mechanical testing, respectively. It was found that as the blend was exposed to increasing levels of shear strain, the speed of sound in the tablets decreased and the tablets became both softer and mechanically weaker. Moreover, the results indicate that two separate tablet material properties (e.g., relative density and Young's modulus) are necessary in order to predict tensile strength. A strategy for hardness prediction is proposed that uses the existing models for Young's modulus and tensile strength of porous materials. Ultrasound testing was found to be very sensitive in differentiating tablets with similar formulation but produced under different processing conditions (e.g., different level of shear strain), thus, providing a fast, and non-destructive method for hardness prediction that could be incorporated to a continuous manufacturing process.Peer reviewe
Labeling Theory
No full textLabeling theory is a sociological and criminological approach to study deviance that focuses on the process of social construction of crime. Labeling theorists attribute a major role to the social definition of the crime, to the process of labelling and stigmatization affecting deviant behavior: by assigning the label of criminal to an offender, a process is engaged that transforms the author of a single offense – or an occasional transgression – into a chronic offender. The core of deviant processes is clearly traceable to the rules that define a given conduct as right or wrong. No behavior is deviant in itself, it becomes so as soon as it is defined as such. The labeling approach therefore calls for serious thought on the power of groups within a company to define a certain behavior as deviant
