The discourse of drug use in Egypt: an interdisciplinary exploratory study

This thesis sets out to better understand how Egyptian society constructs and labels the ‘deviant’ behavior of drug use. However, it is not about drugs per se, it is about scrutinizing the complex process through which Egyptian society encounters, experiences, and regulates behavior. Through an interdisciplinary approach, it builds an alternative and critical understanding of a stigmatized group of individuals by describing how they shape or are shaped by the dynamic system in which they exist. Thus, it creates a conversation between the structures of power that regulate the moral economy of society on the one hand and individuals practicing a role with their substance use on the other. It explores the structural power that disciplinary mechanisms have over ‘deviant behavior’, while simultaneously illustrating that ‘deviant drug users’ are judged according to a variety of unique circumstances and spectrum of acceptability. While some are successfully stigmatized for violating norms, others are able to retain their autonomy and shape their own rules and value systems outside the judgment of mainstream society. So, by using drug use as a lens to examine society, this thesis analyzes the fluidity of power within society in this context and also the ambiguity of behavior within different times and spaces. Ultimately, this thesis shows that deviant behavior like drug use is essential to any society that designates boundaries and rules. For how do individuals know what roles, interactions, behavior, value systems, are legitimate if society doesn’t create a ‘deviant other’ whose transgressions teach right from wrong, lawful from unlawful, and the acceptable from the unacceptable

El Movimiento del Material Granulado y sus Aplicaciones

Muchos procesos industriales tienen incorporado el movimiento de material granulado como mecanismo y factor fundamental de su desempeño, por ejemplo, en la industria del plástico, la materia prima esta conformada por pelets (pequeñas esferas de color); en la fabricación de detergentes el producto tiene la forma de pequeñas gránulos; en el almacenamiento de granos tales como maíz, arroz, legumbres, son considerados como pequeñas partículas de forma conocida; otras aplicaciones tales como: chancadores, molinos, industria farmacéutica, movimiento de tierras, transporte de material, clasificadores, etc. Son ejemplos donde determinar el comportamiento del material granulado es fundamental por sus incidencias económicas. El presente trabajo muestra los avances que un grupo de investigadores han realizado desde hace cuatro años en dicha materia, esta ha consistido en desarrollar nuevos algoritmos e implementados en programas computacionales hechos ad-doc, para capturar el comportamiento del material granulado, especial desarrollo se ha logrado en la evaluación del movimiento de carga en molinos de la minería, así como en clasificadores de partículas y movimiento de material al interior de tolvas de almacenamiento y chutes de traspaso, también en la misma área. En la actualidad se cuenta con una plataforma computacional que permite abordar una variedad de problemas de acuerdo a las solicitudes del medio productivo, a la fecha se han prestado servicios a las empresas Aceros Chile, Compañía Minera Los Pelambres, CODELCO NORTE, Compañía Minera Doña Inés de Collahuasi, CODELCO ANDINA, ELECMETAL, entre otras

Photometric scaling relations of antitruncated stellar discs in S0-Scd galaxies

It has been recently found that the characteristic photometric parameters of antitruncated discs in S0 galaxies follow tight scaling relations. We investigate if similar scaling relations are satisfied by galaxies of other morphological types. We have analysed the trends in several photometric planes relating the characteristic surface brightness and scalelengths of the breaks and the inner and outer discs of local antitruncated S0-Scd galaxies, using published data and fits performed to the surface brightness profiles of two samples of Type-III galaxies in the R and Spitzer 3.6 microns bands. We have performed linear fits to the correlations followed by different galaxy types in each plane, as well as several statistical tests to determine their significance. We have found that: 1) the antitruncated discs of all galaxy types from Sa to Scd obey tight scaling relations both in R and 3.6 microns, as observed in S0s; 2) the majority of these correlations are significant accounting for the numbers of the available data samples; 3) the trends are clearly linear when the characteristic scalelengths are plotted on a logarithmic scale; and 4) the correlations relating the characteristic surface brightnesses of the inner and outer discs and the breaks with the various characteristic scalelengths significantly improve when the latter are normalized to the optical radius of the galaxy. The results suggest that the scaling relations of Type-III discs are independent of the morphological type and the presence (or absence) of bars within the observational uncertainties of the available datasets, although larger and deeper samples are required to confirm this. The tight structural coupling implied by these scaling relations impose strong constraints on the mechanisms proposed for explaining the formation of antitruncated stellar discs in the galaxies across the whole Hubble Sequence (Abridged).Comment: Accepted for publication in Astronomy & Astrophysics, 18 pages, 12 figures, 7 table

The Social Structure of Golfo Dulce Bottlenose Dolphins (\u3ci\u3eTursiops truncatus\u3c/i\u3e) and the Influence of Behavioural State

Ecological factors such as habitat and food availability affect the social structure of bottlenose dolphins (Tursiops spp.). Here, we describe the social structure of bottlenose dolphins (T. truncatus) in Golfo Dulce, Costa Rica, a semi-enclosed, fjord-like tropical embayment resembling a pelagic system. We also examine behaviour-linked social strategies by comparing social structure relative to behavioural state: feeding versus non-feeding. We analysed 333 sightings over 210 days from boat-based surveys. Despite the uniqueness of the area, the 47 analysed adults had a social structure similar to other populations: a well-differentiated fission-fusion society with sex-specific patterns of associations and aggression. These results indicate that differences in social structure relative to other populations were a matter of degree. Association strength of dyads was highly correlated across behavioural states, indicating constraints on social fluidity. Males displayed a marked difference in lagged association rate and females displayed a small difference in association homogeneity between states. We suggest this difference in population-wide social connections between behavioural states, particularly for males, was due to mating strategies, a pressure which is strongest during non-feeding behaviour and relaxed during feeding. This finding highlights the importance of considering behavioural state when examining individual bonds and the behavioural plasticity for which the bottlenose dolphin is well known

Chile’s enduring educational segregation: a trend unchanged by different cycles of reform

Socioeconomic segregation continues to be a central issue for education systems in which market-driven reforms have been implemented. This study analyses trends of socioeconomic segregation in Chile (1999–2018), considering a period with an absence of policies aimed at reducing segregation (1999–2007) and a later stage (2008–2015) when measures were implemented with the potential to affect the socioeconomic composition of schools. Results show that the segregation of both disadvantaged and wealthy students increased to extremely high levels during the first period, and has not shown signs of any significant decrease since then. The slight reduction observed in the second period is associated with changes regarding school fees in the private subsidised education sector rather than the selectivity status of the schools. The challenges faced in fostering greater socioeconomic integration within a market-driven educational system are discussed in this article

Educational video games to improve the learning process

The pandemic has made us quickly migrate to virtual environments, for this reason, we must look for quality education mechanisms, thus continuing with the same level of traditional teaching. This research aims to determine the influence of an educational video game in improving the learning process, for which a study was carried out on first-cycle university students. The level of the research is explanatory, of the applied type, with a quantitative approach and quasi-experimental design. We worked with two groups already formed in which 65 students participated. The following results were obtained: an increase in the grade of motivation of 12.9%, an improvement in the acquired knowledge indicator of 46.34%, and an improvement in the obtained qualification indicator of 12.77%. Therefore, it is concluded that an educational video game influences the motivation, acquisition, and application of learning
